Assessment of the appropriate cut-off point in glucose challenge test based on the risk of gestational diabetes in pregnant women

Abstract: Introduction: Determination of the appropriate basis in glucose challenge test is considered as the most important problems discussed in screening for Gestational Diabetes Mellitus. Therefore, this study was conducted with aim to assess the appropriate cut-off point in glucose challenge test in pregnant women. Methods: In this study, data of Iranian pregnant women without diabetes referring to Rafsanjan gynecology clinics for assessment of gestational diabetes were collected. GCT was performed for the women in 24 to 28 weeks of pregnancy. Oral Glucose Tolerance Test was performed for women who their test result was â�¥135 mg/dl and â�¤200 mg/dl. The OGTT results were interpreted by Carpenter and Coustan criteria. Finally, the appropriate cut-off point of GCT was calculated by SPSS software (version 22) and the ROC curve. Results: The results of GCT showed that the maximum and minimum values of GCT were 93 and 199 mg/dl respectively, with meanÂ±SD of 161.99Â±15.83 mg/dl. 235 cases of pregnant women had positive GTT test. According to the ROC curves for all study population, GTT cut-off point was 140 mg/dl with 97 sensitivity, in low-risk group for gestational diabetes was 147 mg/dl with 96 sensitivity and for high risk group was 135 mg/dl with 100 sensitivity and had the most predictive value. Conclusion: Suitable cut-off point in GCT for gestational diabetes is different in low and high risk pregnant women. Depending on the presence or absence of risk factors in mothers, we can reduce or increase the cut-off point of the GCT.

Understanding Collapse: Ancient History and Modern Myths

Abstract: Understanding Collapse explores the collapse of ancient civilisations, such as the Roman Empire, the Maya, and Easter Island. In this lively survey, Guy D. Middleton critically examines our ideas about collapse - how we explain it and how we have constructed potentially misleading myths around collapses - showing how and why collapse of societies was a much more complex phenomenon than is often admitted. Rather than positing a single explanatory model of collapse - economic, social, or environmental - Middleton gives full consideration to the overlooked resilience in communities of ancient peoples and the choices that they made. He offers a fresh interpretation of collapse that will be accessible to both students and scholars. The book is an engaging, introductory-level survey of collapse in the archaeology/history literature, which will be ideal for use in courses on the collapse of civilizations, sustainability, and climate change. It includes up-to-date case studies of famous and less well-known examples of collapses, and is illustrated with 25 black and white illustrations, 3 line drawings, 16 tables and 18 maps.

Biological activities of a garlic–Cirsium setidens Nakai blend fermented with Leuconostoc mesenteroides

Abstract: In this study, we investigated the antioxidant‐ and immune‐stimulating activities of various garlic–Cirsium setidens Nakai blends (fermented and unfermented). The levels of S‐allyl cysteine increased by 2.5 times while pectolinarigenin (an anti‐inflammatory compound) increased about six times (from 1.1 ± 0.04 mg/g to 6.70 ± 0.12 mg/g) after the garlic–Cirsium setidens Nakai (80:20%, respectively) blend (S4) was fermented with Leuconostoc mesenteroides KCTC 13302. The ferric reducing ability and DPPH radical scavenging activities of all the samples increased significantly after fermentation. Ethanolic extracts of the fermented samples significantly enhanced RAW 264.7 macrophage proliferation in a dose‐dependent manner and induced nitric oxide production. Among the samples, S6 and S8 stimulated the highest levels of nitric oxide (NO) production. S6 significantly induced proinflammatory cytokines TNF‐α and IL‐1β as well as an anti‐inflammatory cytokine IL‐10 relative to control. Since the resolution of an infection would require a harmonized interplay of proinflammatory factors and anti‐inflammatory cytokines, consumption of S6 could be helpful in promoting health.

Impact of n-3 docosapentaenoic acid (DPA) supplementation on n-3 fatty acid composition of tissues in rats

Abstract: Objectives and study ::: The role of Polyunsaturated Fatty Acids (PUFA) n-3 on lipid metabolism is well known. However, most research focuses on docosahexaenoic acid (DHA, C22:6 n-3) and eicosapentaenoic acid (EPA, C20:5 n-3). Few studies concern docosapentaenoic acid n-3 (DPA n-3, C22:5 n-3), which is not commercially available in sufficient amount for in vivo studies. This fatty acid is an intermediate between EPA and DHA in the n-3 PUFA conversion pathway from α-linolenic acid (ALA, C18:3 n-3). It could be of interest both for DPA ability to be converted to EPA or DHA, mostly in the liver; and for its potential specific physiological effects. To our knowledge, no studies have been able to observe globally the specific enrichment of this fatty acid in the tissues when it was supplemented in vivo. ::: The objective of this study is therefore to examine the effect of DPA supplementation at a physiological dose on the PUFA composition of the main tissues in rats in order to guide future studies towards the search for physiological effects. ::: Methods ::: DPA was purified by preparative liquid chromatography. Two groups of Sprague Dawley male rats (n= 8 / group) were fed for 3 weeks from weaning with a 10% weight lipid diet supplemented or not with 0.5% DPA of total fatty acids (TFA) and containing ALA (2.3% of TFA, ratio n-6/n-3= 5). The TFA composition of 20 tissues was investigated by gas chromatography coupled to a mass spectrometer. The two groups were compared by Student's t-test (p< 0.05). ::: Results ::: When supplemented, the proportion of DPA is significantly increased in the heart (x2.1), lung (x1.8), spleen (x1.6), bone marrow (x1.5) and kidney (X1.3). Its proportion tends to increase in the red blood cells (x1.4) and the pancreas (x1.2) but remains stable in the liver, plasma, brain and retina that are known to be impacted with diets supplemented with EPA or with DHA. ::: DHA status was significantly increased in the spleen (x1.2), lung (x1.2) and tends to increase in the bone marrow (x1.6). DPA supplementation would therefore increase the conversion to DHA. ::: The proportions of EPA were significantly increased in the liver (x2.0), plasma (x2.0), spleen (x1.5), lung (x1.3) and bone marrow (x1.1). This would confirm direct or indirect retroconversion through DHA from DPA to EPA. ::: Concerning the n-6 series PUFAs in competition with the enzymes of the n-3 conversion pathway, the proportions of DPA n-6 (C22:5 n-6) and arachidonic acid (C20:4 n- 6) decreased in some tissues specifically (red blood cells, heart, kidney, spleen, lung). ::: Conclusion ::: DPA supplementation at 0.5% of TFA results in enrichment of n-3 PUFA and depletion of n-6 PUFAs targeted in some tissues. This suggests a potential and specific action of this fatty acid. Future studies are now scheduled to determine the potential physiological effects of DPA in these organs as compared to DHA and EPA.

George Hore's gallipoli experience: A light horseman's record of the gallipoli campaign - the 'ANZAC panorama' and its background

Abstract: Many of those who served in the ill-fated Gallipoli campaign in 1915 sought to record their experiences, usually in letters and diaries, occasionally in graphic form, though few had the skills or materials to do this. Leslie Fraser Standish Hore, known as George, one of the few surviving officers of the 8th Light Horse Regiment, whose Gallipoli experience culminated in the disaster of the attack at The Nek on 7 August, left a memorable record of that experience in three forms: firstly, in a series of observant coloured sketches; secondly in a letter to his wife which gave an account of the harrowing event; and thirdly and perhaps most significantly, he produced what he called the 'Anzac Panorama'. Informed by his pictures and by six smaller panoramas he had sketched during the campaign, it was completed from memory after the Gallipoli campaign was over. Hore then had it printed in Cairo, probably early in 1916. The panorama gives an interesting representation of Australian positions on 7 August, the day of the assault on Turkish positions at The Nek by the 8th and 10th Australian Light Horse Regiments. This article outlines Hore's background, and goes on to discuss all three aspects of his Gallipoli experience: his sketches, his account of the attack, in which he was wounded, and finally the 'Anzac Panorama', which brought together all that had gone before. While it is but one part of a considerable corpus of sketching and painting, he clearly intended it to be the most significant part. He was well fitted to achieve this.


Introduction to Structure and Motion Factorization

Abstract: The chapter reviews some popular algorithms for structure and motion factorization. We first introduce the problem of structure and motion recovery. Then, present the main idea of the following factorization algorithms for different kinds of scenarios under different projection models. (i) Structure and motion factorization of rigid objects under affine assumption and its extension to perspective camera model; (ii) Nonrigid factorization under both affine and perspective projection model; (iii) Structure factorization of multiple and articulated objects.


Effect of a magnetic field on massive star winds I: mass-loss and velocity for a dipole field

Abstract: We generalize the Rigid-Field Hydrodynamic equations to accommodate arbitrary magnetic field topologies, resulting in a new Arbitrary Rigid-Field hydrodynamic (ARFHD) formalism. We undertake a critical point calculation of the steady-state ARFHD equations with a CAK-type radiative acceleration and determine the effects of a dipole magnetic field on the usual CAK mass-loss rate and velocity structure. Enforcing the proper optically-thin limit for the radiative line-acceleration is found to decrease both the mass-loss and wind acceleration, while rotation boosts both properties. We define optically-thin-correction and rotation parameters to quantify these effects on the global mass-loss rate and develop scaling laws for the surface mass-flux as a function of surface colatitude. These scaling laws are found to agree with previous laws derived from magnetohydrodynamic simulations of magnetospheres. The dipole magnetosphere velocity structure is found to differ from a global beta-velocity law, which contradicts a central assumption of the previously-developed XADM model of X-ray emission from magnetospheres.

Testing the Gaussianity and Statistical Isotropy of the Universe

Abstract: The last few years have seen a surge in excitement about measurements of statistics of the primordial fluctuations beyond the power spectrum. New ideas for precision tests of Gaussianity and statistical isotropy in the data are developing simultaneously with proposals for a wide range of new theoretical possibilities. From both the observations and theory, it has become clear that there is a huge discovery potential from upcoming measurements. The twin principles of statistical isotropy and homogeneity are a crucial ingredient in obtaining most important results in modern cosmology. For example, with these assumptions temperature and density fluctuations in different directions on the sky can be averaged out, leading to accurate constraints on cosmological parameters that we have today. Nevertheless, there is no fundamental reason why these must be obeyed by our universe. Statistical isotropy and homogeneity are starting to be sharply tested using the Cosmic Microwave Background (CMB) and large-scale structure data. Recently, there has been particular activity in these areas, given Wilkinson Microwave Anisotropy Probe’s remarkable maps, combined with claims of large-angle ’anomalies’ indicating departures from statistical isotropy as predicted by standard inflationary models. The statement that primordial curvature fluctuations are nearly Gaussian on scales measured by the CMB is remarkably precise, but doesn’t reveal much about their source. Current constraints on the amplitude of the three-point correlation function of fluctuations are nearly four orders of magnitude above predictions from single field slow-roll inflation models and at least an order of magnitude above what is expected just from non-linearities that develop after the primordial spectrum is laid down. There is a wide spectrum of interesting models that can be ruled out by tightening this constraint; conversely, a detection of non-Gaussianity would rule out single field slow-roll inflation. While current observations of the CMB fluctuations provide reasonably strong evidence for a primordial source of fluctuations from inflaton, only measurements of higher order statistics can truly shed light on the physics of inflation. Departures from statistical isotropy and Gaussianity involve a rich set of observable quantities, with diverse signatures that can be measured in the CMB or in large-scale structure using sophisticated statistical methods. These signatures, which carry information about

電離層F2 層臨界頻率（foF2）之自動判讀改進與正確性判別

Abstract: The topic of this thesis is to improve the ionograms scaling results of the critical frequency of F2 layer (foF2). Comparing the foF2 scaling results between the automatic scaling program by using a fuzzy segmentation and a connectedness algorithm and by human eyes, the absolute values of differences between two scaling results less than 1 MHz are less than 60% for the chosen 2304 ionograms. The improved automatic scaling program filters the echo not belonging to the F layer, and then using the F layer echoes to determine the foF2. The absolute values of differences between two scaling results less than 1 MHz are more than 85%, better than the previous program. This thesis also discusses the accuracy of the scaling results. The 2304 ionograms were obtained by the Dynasonde that was established at Dong-Hwa University in Hualien, Taiwan since 2010.

Energy scaling law for nanostructured materials

Abstract: The equilibrium binding energy is an important factor in the design of materials and devices. However, it presents great computational challenges for materials built up from nanostructures. Here we investigate the binding-energy scaling law from first-principles calculations. We show that the equilibrium binding energy per atom between identical nanostructures can scale up or down with nanostructure size. From the energy scaling law, we predict finite large-size limits of binding energy per atom. We find that there are two competing factors in the determination of the binding energy: Nonadditivities of van der Waals coefficients and center-to-center distance between nanostructures. To uncode the detail, the nonadditivity of the static multipole polarizability is investigated. We find that the higher-order multipole polarizability displays ultra-strong intrinsic nonadditivity, no matter if the dipole polarizability is additive or not.

Quark-Gluon Plasma

Abstract: An elementary introduction to the physics of quark-gluon plasma is given. We start with a sketchy presentation of the Quantum Chromodynamics which is the fundamental theory of strong interactions. The structure of hadrons built up of quarks and gluons is briefly discussed with a special emphasis on the confinement hypothesis. Then, we explain what is the quark-gluon plasma and consider why and when the hadrons can dissolve liberating the quarks and gluons. The heavy-ion collisions at high-energies, which provide a unique opportunity to get a droplet of the quark-gluon plasma in the terrestrial conditions, are described. We also consider the most promising experimental signatures of the quark-gluon plasma produced in nucleus-nucleus collisions. At the end, the perspectives of the quark-gluon plasma studies at the future accelerators are mentioned.

A Study on the Mixed Model Approach and Symbol Probability Weighting Function for Maximization of Inter-Speaker Variation

Abstract: Recently, most of the speaker verification systems are based on the pattern recognition approach method. And performance of the pattern-classifier depends on how to classify a variety of speakers' feature parameters. In order to classify feature parameters efficiently and effectively, it is of great importance to enlarge variations between speakers and effectively measure distances between feature parameters. Therefore, this paper would suggest the positively mixed model scheme that can enlarge inter-speaker variation by searching the individual model with world model at the same time. During decision procedure, we can maximize inter-speaker variation by using the proposed mixed model scheme. We also make use of a symbol probability weighting function in this system so as to reduce vector quantization errors by measuring symbol probability derived from the distance rate of between the world codebook and individual codebook. As the result of our experiment using this method, we could halve the Detection Cost Function (DCF) of the system from .

The Effect of General Relativistic Precession on Tidal Disruption Events from Eccentric Nuclear Disks

Abstract: An eccentric nuclear disk consists of stars moving on apsidally-aligned orbits around a central black hole. The secular gravitational torques that dynamically stabilize these disks can also produce tidal disruption events (TDEs) at very high rates in Newtonian gravity. General relativity, however, is known to quench secular torques via rapid apsidal precession. ::: Here we show that for a disk to black hole mass ratio $\gtrsim 10^{-3}$, the system is in the full loss cone regime. The magnitude of the torque per orbital period acting on a stellar orbit means that general relativistic precession does not have a major effect on the dynamics. Thus we find that TDE rates from eccentric nuclear disks are not affected by general relativistic precession. Furthermore, we show that orbital elements between successive TDEs from eccentric nuclear disks are correlated, potentially resulting in unique observational signatures.

Commutation relations for the electromagnetic field in the presence of dielectrics and conductors

Abstract: Motivated by recent investigations on the Casimir effect, we work out in detail the commutation relations satisfied by the quantized electromagnetic field in the presence of one or two dielectric slabs, with arbitrary dispersive and dissipative properties. In agreement with results derived by previous authors, we explicitly show that at all points in the empty region between the slabs, including their surfaces, the electromagnetic fields always satisfy free-field canonical equal-time commutation relations. This result is a consequence of general analyticity and detailed fall-off properties at large frequencies satisfied by the reflection coefficients of all real materials. It is also shown that this result is not obtained in the case of conductors, if the latter are modelled as perfect mirrors. In such a case, the free-field form of the commutation relations is recovered only at large distances from the mirrors. Failure of perfect-mirror boundary conditions to reproduce the correct form of the commutation relations near the surfaces of the conductors suggests that caution should be used when these idealized boundary conditions are used in investigations of proximity phenomena originating from the quantized electromagnetic field, like the Casimir effect.

A k-deformed Model of Growing Complex Networks with Fitness

Abstract: The Barab\'asi-Bianconi (BB) fitness model can be solved by a mapping between the original network growth model to an idealized bosonic gas. The well-known transition to Bose-Einstein condensation in the latter then corresponds to the emergence of"super-hubs"in the network model. Motivated by the preservation of the scale-free property, thermodynamic stability and self-duality, we generalize the original extensive mapping of the BB fitness model by using the nonextensive Kaniadakis k-distribution. Through numerical simulation and mean-field calculations we show that deviations from extensivity do not compromise qualitative features of the phase transition. Analysis of the critical temperature yields a monotonically decreasing dependence on the nonextensive parameter k.

Cosmic Ray Removal in Fiber Spectroscopic Image

Abstract: Single-exposure spectra in large spectral surveys are valuable for time domain studies such as stellar variability, but there is no available method to eliminate cosmic rays for single-exposure, multi-fiber spectral images. In this paper, we describe a new method to detect and remove cosmic rays in multi-fiber spectroscopic single exposures. Through the use of two-dimensional profile fitting and a noise model that considers the position-dependent errors, we successfully detect as many as 80% of the cosmic rays and correct the cosmic ray polluted pixels to an average accuracy of 97.8%. Multiple tests and comparisons with both simulated data and real LAMOST data show that the method works properly in detection rate, false detection rate, and validity of cosmic ray correction.

Exceptional points in the thermoacoustic spectrum

Abstract: Exceptional points are found in the spectrum of a prototypical thermoacoustic system as the parameters of the flame transfer function are varied. At these points, two eigenvalues and the associated eigenfunctions coalesce. The system's sensitivity to changes in the parameters becomes infinite. Two eigenvalue branches collide at the exceptional point as the interaction index is increased. One branch originates from a purely acoustic mode, whereas the other branch originates from an intrinsic thermoacoustic mode. The existence of exceptional points in thermoacoustic systems has implications for physical understanding, computing, modeling and control.

Spin polarization effects in a two dimensional mesoscopic electronic structure with Rashba spin-orbit and lateral confinement

Abstract: Because of the peculiar coupling of spatial and spin degrees of freedom effected by the Rashba spin-orbit interaction, lateral confinement of a two dimensional electronic system leads to a finite transverse spin polarization near the longitudinal edges of a current carrying quantum wire. The sign of this component of the polarization is opposite at the two edges and can be reversed upon inversion of the current. Interestingly for small spin orbit coupling this is the largest contribution to the total polarization, its magnitude being of second order in the coupling constant. As a consequence this phenomenon cannot be revealed in lowest order perturbative approaches. An in plane spin polarization component is also present that is perpendicular to the current. Within the same model this component would be also present in the bulk. On the other hand while in the latter case its magnitude is linear in the coupling constant, we find that it only represents a third order effect in the wire geometry. Our results are consistent with a general rigorous argument on the parity of the components of the spin polarization with respect to the sign of the spin orbit coupling constant.


Do we need a new family of optical-NIR extinction laws?

Abstract: I consider whether we can significantly improve the Cardelli et al. (1989) family of extinction laws using new data and techniques. There are six different aspects that need to be treated: The use of monochromatic quantities, the three different wavelength regimes (NIR, optical and UV), the sample, and the photometric calibration. Excluding the behavior in the NIR and UV, I discuss the other four aspects and propose a new family of extinction laws derived from VLT/FLAMES and HST/WFC3 data.


Gamma rays and cosmic rays in supernova remnants with radiative cooling

Abstract: The evolution of supernova remnants (SRN's) is followed numerically taking into account the non-linear effects of particle acceleration in shock waves. These high energy particles produce neutral pions by collisions with the thermal plasma and these π 0 's decay into the observable γ-rays. The cosmic rays are treated as a fluid and the time variation of the adiabatic index during the remnant evolution of the cosmic rays as well as of the mean diffusion coefficient are estimated dynamically by a simplified theory. Several SNR models with different efficiencies for the conversion of the supernova explosion energy into cosmic rays depending on physical parameter are analyzed.


Non-thermal emission from stellar bow shocks

Abstract: Since the detection of non-thermal radio emission from the bow shock of the massive runaway star BD +43$^{\circ}$3654 simple models have predicted high-energy emission, at X and gamma-rays, from these Galactic sources. Observational searches for this emission so far give no conclusive evidence but a few candidates at gamma rays. In this work we aim at developing a more sophisticated model for the non-thermal emission from massive runaway star bow shocks. The main goal is to establish whether these systems are efficient non-thermal emitters, even if they are not strong enough to be yet detected. For modeling the collision between the stellar wind and the interstellar medium we use 2D hydrodynamic simulations. We then adopt the flow profile of the wind and the ambient medium obtained with the simulation as the plasma state for solving the transport of energetic particles injected in the system, and the non-thermal emission they produce. For this purpose we solve a 3D (2 spatial + energy) advection-diffusion equation in the test-particle approximation. We find that a massive runaway star with a powerful wind converts 0.16-0.4% of the power injected in electrons into non-thermal emission, mostly produced by inverse Compton scattering of dust-emitted photons by relativistic electrons, and secondly by synchrotron radiation. This represents a fraction of $\sim$ $10^{-5}-10^{-4}$ of the wind kinetic power. Given the better sensibility of current instruments at radio wavelengths theses systems are more prone to be detected at radio through the synchrotron emission they produce rather than at gamma energies.


A WISE Survey of Circumstellar Disks in Taurus

Abstract: We have compiled photometry at 3.4, 4.6, 12 and 22 $\mu$m from the all-sky survey performed by the Wide-field Infrared Survey Explorer (WISE) for all known members of the Taurus complex of dark clouds. Using these data and photometry from the Spitzer Space Telescope, we have identified members with infrared excess emission from circumstellar disks and have estimated the evolutionary stages of the detected disks, which include 31 new full disks and 16 new candidate transitional, evolved, evolved transitional, and debris disks. We have also used the WISE All-Sky Source Catalog to search for new disk-bearing members of Taurus based on their red infrared colors. Through optical and near-infrared spectroscopy, we have confirmed 26 new members with spectral types of M1 - M7. The census of disk-bearing stars in Taurus should now be largely complete for spectral types earlier than $\sim$M8 ($M \gtrsim 0.03$ $M_\odot$).


The Diffuse Light of the Universe

Abstract: In 1965, the discovery of a new type of uniform radiation, located between radiowaves and infrared light, was accidental. Known today as Cosmic Microwave background (CMB), this diffuse radiation is commonly interpreted as a fossil light released in an early hot and dense universe and constitutes today the main 'pilar' of the big bang cosmology. Considerable efforts have been devoted to derive fundamental cosmological parameters from the characteristics of this radiation that led to a surprising universe that is shaped by at least three major unknown components: inflation, dark matter and dark energy. This is an important weakness of the present consensus cosmological model that justifies raising several questions on the CMB interpretation. Can we consider its cosmological nature as undisputable? Do other possible interpretations exist in the context of other cosmological theories or simply as a result of other physical mechanisms that could account for it? In an effort to questioning the validity of scientific hypotheses and the under-determination of theories compared to observations, we examine here the difficulties that still exist on the interpretation of this diffuse radiation and explore other proposed tracks to explain its origin. We discuss previous historical concepts of diffuse radiation before and after the CMB discovery and underline the limit of our present understanding.


Bandgap engineering of monolayer MoS2 under strain: A DFT study

Abstract: In this paper, density functional theory calculations are used to investigate the monolayer MoS2 in terms of the strain by analyzing the structure parameters: the bandgap, the density of states (DOS) and the Milliken charges. The calculations indicate that an increasing external stain tends to depress the ripple structure with a shorter S-S interlayer spacing and to enlarge the length of the Mo-S bond. Tensile strain dramatically alteres the bandgap; however, compressive strain almost does not. The change in the bandgap is explained by an analysis of the DOS, the partial density of states (PDOS), the structure parameters and the Mulliken charge distribution. The effects of strain on the Mulliken charge and the length of the Mo-S band cause bandgap differences under tensile and compressive strain.

Abstract: In the design process of complex systems, the designer is solving an optimization problem, which involves different disciplines and where all design criteria have to be optimized simultaneously. Mathematically this problem can be reduced to a vector optimization problem. The solution of this problem is not unique and is represented by a Pareto surface in the space of the objective functions. Once a Pareto solution is obtained, it may be very useful for the decision-maker to be able to perform a quick local approximation in the vicinity of this Pareto solution in order to explore its sensitivity. In this paper, a method for obtaining linear and quadratic local approximations of the Pareto surface is derived. A few examples are considered. 2008 American Institute of Physics

The Motion of Interplanetary Dust Particles

Abstract: Radial velocity measurements on the solar MgI 5183.618A Fraunhofer absorption line in the Zodiacal Light spectrum have been made with a microprocessor-controlled servo-stabilised Fabry-Perot interferometer. Observations were made at 5 and 10 degree intervals in the ecliptic plane between morning and evening elongations of 25 degrees. These new data are of much greater precision and coverage than any previously obtained. Obtained over a two year period, the observations show a consistent evening/morning asymmetry in the radial velocity curve with the Gegenschein receding from the Earth at 4 Km/sec. These data do not support the hypothesis that the majority of interplanetary dust grains are in hyperbolic trajectories.

Effect of Plasma Irradiation on $Cd I_2$ films

Abstract: The effect of plasma irradiation is studied systematically on a 4H polytype (002) oriented ${\rm CdI_2}$ stoichiometric film having compressive residual stress. Plasma irradiation was found to change the orientation to (110) of the film at certain moderate irradiation distances. A linear decrease in grain size and residual stress was observed with decreasing irradiation distance (or increasing ion energy) consistent with both structural and morphological observations. The direct optical energy gap ${\rm E_g}$ was found to increase linearly at the rate ${\rm 15\mu eV/atm}$ with the compressive stress. The combined data of present compressive stress and from earlier reported tensile stress show a consistent trend of ${\rm E_g}$ change with stress. The iodine-iodine distance in the unit cell could be responsible for the observed change in ${\rm E_g}$ with stress.

The semi-constrained NMSSM in light of muon g-2, LHC, and dark matter constraints

Abstract: The semi-constrained NMSSM (scNMSSM) extends the MSSM by a singlet field, and requires unification of the soft SUSY breaking terms in the squark and slepton sectors, while it allows that in the Higgs sector to be different. We try to interpret the muon g-2 in the scNMSSM, under the constraints of 125 GeV Higgs data, B physics, searches for low and high mass resonances, searches for SUSY particles at the LHC, dark matter relic density by WMAP/Planck, and direct searches for dark matter by LUX, XENON1T, and PandaX-II. We find that under the above constraints, the scNMSSM can still (i) satisfy muon g-2 at 1$\sigma$ level, with a light muon sneutrino and light chargino; (ii) predict a highly-singlet-dominated 95~GeV Higgs, with a diphoton rate as hinted at by CMS data, because of a light higgsino-like chargino and moderate $\lambda$; (iii) get low fine tuning from the GUT scale with small $\mu_{\rm eff},\, M_0,\, M_{1/2},\, {\rm and}\, A_0$, with a lighter stop mass which can be as low as about 500 GeV, which can be further checked in future studies with search results from the 13~TeV LHC; (iv) have the lightest neutralino be singlino-dominated or higgsino-dominated, while the bino and wino are heavier because of high gluino bounds at the LHC and universal gaugino conditions at the GUT scale; (v) satisfy all the above constraints, although it is not easy for the lightest neutralino, as the only dark matter candidate, to get enough relic density. Several ways to increase relic density are discussed.


Stochastic Orders Generated by Generalized Convex Functions

Abstract: We give a survey of the use of concepts of generalized convex functions in the theory of stochastic order relations. We describe the use of (a, b)-concavity, antistarshapedness, and t-quasi-unimodality in the theory of individual decisions under risk. In the case of multivariate distributions, we show how supermodularity and directional convexity arise naturally in the context of dependence orderings. Moreover, we state some new results and some open problems connected with increasing quasiconcave ordering and linear convex ordering.

Resonance Stark effect in OH and H$sub 2$O interstellar masers


Near field scattered by subsurface particles

Abstract: A volume integral method is developped in order to study the scattering of a plane wave by a small particle placed below a metallic surface. The scattering patterns produced in the near field are analysed. For p-polarization, a plasmon is excited producing interferences along the surface. It is shown that this interference pattern might be used to measure the dielectric constant of the metal. The scattered field has a pronounced maxima for p-polarization if the particle is close to the interface. This effect is due to a resonant interaction between the surface and the dipole already identified in the context of SERS as an image enhancement effect. Finally, the resolution of a near field detection of a subsurface scatterer is discussed on the basis of the transverse extension of the scattered field.

Atmospheric Neutrino Mixing and b → s Transitions: Testing Lopsided SO(10) Flavor Structure in B physics

Abstract: We point out that the correlation between the large atmospheric neutrino mixing and the b! s transition, if exists, comes from the lopsided flavor structure in SO(10) grand unification theory. We suggest testing the correlation by studying the deviation of SKS and S�'KS from the standard model predictions along with the constraints fromMBS and b! s in a realistic SO(10) model with lopsided flavor structure. We find a specific correlation between SKS and S�'KS that is intrinsic to the lopsided structure and discuss how to confirm or rule out this flavor pattern by the more accurate measurements of these CP violation quantities in B decay. The standard model (SM), although has passed many precision experimental tests, still has a number of out- standing problems which beg for a more fundamental the- ory. In terms of phenomenology, there are many places to test the more fundamental theory and, quite often, it is not one piece of phenomenology but a specific pattern of many pieces of phenomenology that fulfils this job. Neutrino oscillation clearly indicates the beyond SM physics in that it violates the accidental symmetry Le,µ,� of SM lepton flavor. Moreover, the tiny neutrino masses can be most naturally explained by the seesaw mech- anism (1), indicating the Majorana nature of neutrinos that leads to violation of another accidental symmetry B − L of SM at a very high scale close to the grand unification theory (GUT) scale. For this reason, study- ing neutrino oscillation in the GUT framework becomes particularly interesting. In SO(10) GUT, quarks and leptons are unified into a single 16 multiplet, yet experimental data shows that the 2-3 (generation) mixing is dramatically different in the quark and lepton sectors. While the quark mixing an- gle θ CKM is around 0.04, the lepton mixing angle θ PMNS (atmospheric mixing angle) is quite large and could be a maximum of π/4. This difference can be rather naturally explained by the lopsidedness in the 2-3 sector of mass matrices of down-type quarks and charged leptons:


Real Photon Physics Experiments At JLAB Using The Hall B Photon Tagger

Abstract: Data on real-photon induced reactions have been taken using the Tagged Photon Facility (TPF) and the Continuous Electron Beam Accelerator Facility (CEBAF) at the Thomas Jefferson National Accelerator Facility (JLab) during the first year of running in Hall B. These data have been taken for the purpose of investigating the electromagnetic structure of mesons, nucleons, and nuclei. This report summarizes the status of these experiments.


Nature and GRBs

Abstract: Nature has published a third of the highest cited GRB papers, as tracked by ADS in May 2008, and those papers are amongst the highest cited astronomy papers in the journal. In the early days after the discovery of counterparts, almost any new observations were interesting. But as the GRB field has matured we are looking to cut back on the numbers of GRB papers published, seeking only the truly novel and groundbreaking ones. The days of groups of papers about a single burst are over ?we now encourage groups to combine their data and submit a single comprehensive paper. As always, I encourage authors to contact me in advance of submission to allow me to assess suitability and advise on presentation.

Hypergeometric Forms for Ising-Class Integrals - eScholarship

Abstract: We apply experimental-mathematical principles to analyze certain integrals relevant to the Ising theory of solid-state physics. We find representations of the these integrals in terms of Meijer G-functions and nested-Barnes integrals. Our investigations began by computing 500-digit numerical values of Cn,k, namely a 2-D array of Ising integrals for all integers n, k where n is in [2,12] and k is in [0,25]. We found that some Cn,k enjoy exact evaluations involving Dirichlet L-functions or the Riemann zeta function. In theprocess of analyzing hypergeometric representations, we found -- experimentally and strikingly -- that the Cn,k almost certainly satisfy certain inter-indicial relations including discrete k-recursions. Using generating functions, differential theory, complex analysis, and Wilf-Zeilberger algorithms we are able to prove some central cases of these relations.

A revision of root locus method with applications

Abstract: Abstract The paper investigates applications of the root-locus (RL) method to analysis and design of closed loop systems with arbitrary loop transfer functions. Novel analytic sketching rules have been derived first. These rules are applicable to a wide range of transfer functions: rational, fractional and non-rational ones in general, those with time-delays incorporated at various locations, as well as transfer functions describing distributed-parameter systems. An original, straightforward numerical procedure for plotting the root locus has been proposed next. By means of the derived techniques, a generalization of the pole-placement method, which is applicable to control design of both rational and non-rational processes has been proposed also. Finally, it has been shown that RL technique can be very effectively used to investigate the influence of open loop dead-time variations to closed loop poles. It is of particular interest to stress that the techniques proposed and analyzed in this work are exact, in the sense that no rational approximations of infinite-dimensional systems have been utilized. All results have been thoroughly illustrated by numerical examples.

Inhärente Kontrollprädikate im Deutschen

Abstract: This paper adds a new dimension to the study of obligatory control: the distinction of inherent vs. non-inherent control predicates. Inherent control predicates are clause-embedding predicates that invariantly require identification of one of its individual arguments with an argument of the embedded predicate, irrespective of the type of clausal complement. The paper thus identifies instances of control in German finite verb-final and V2 complements and in nominalized clausal arguments, thereby adding data to the discussion of finite control. The lexical property of inherent control results from various factors: one major factor is event coherence -the respective predicates and their clausal complements denote a coherent event, which disallows incompatible local and temporal modifiers in matrix clause and embedded clause (e.g. with implicative verbs such as wagen 'dare'). As a consequence, matrix predicate and embedded predicate have to share at least one participant. In addition, there are various subgroups of inherent control predicates that do not exhibit event coherence. Here, the inherence of the control relation results a) from the sincerity conditions of the matrix predicates (with directive and commissive predicates), b) the fact that the clausal argument is integrated as "direct predication" of the matrix predicate's internal argument (e.g. vorwerfen 'reproach'), or c) semantic specialization of the matrix predicate in contrast to semantically similar predicates, which involves self-related attitudes or speech acts (e.g. bereuen 'regret/repent').

Solar flare telescope and 10-cm new coronagraph

Abstract: Two new telescopes were built at the National Astronomical Observatory of Japan, i.e. the Solar Flare Telescope and the 10-cm New Coronagraph. The Solar Flare Telescope was constructed at Mitaka to make observations of photospheric velocity fields, vector magnetic fields, and Hα and continuum images of active regions simultaneously. The whole system will be completed in 1991. The 10-cm new coronagraph, which was developed to make precise measurements of the coronal intensity in several wavelengths, has already been in operation for one year at the Norikura Solar Observatory. At present the accuracy of about 10-6 of the solar disk intensity is achieved in continuum light, but further improvement in the photometric accuracy remains to be done.


Implementing Diffie-Hellman key exchange using quantum EPR pairs

Abstract: This paper implements the concepts of perfect forward secrecy and the Diffie-Hellman key exchange using EPR pairs to establish and share a secret key between two non-authenticated parties and transfer messages between them without the risk of compromise. Current implementations of quantum cryptography are based on the BB84 protocol, which is susceptible to siphoning attacks on the multiple photons emitted by practical laser sources. This makes BB84-based quantum cryptography protocol unsuitable for network computing environments. Diffie-Hellman does not require the two parties to be mutually authenticated to each other, yet it can provide a basis for a number of authenticated protocols, most notably the concept of perfect forward secrecy. The work proposed in this paper provides a new direction in utilizing quantum EPR pairs in quantum key exchange. Although, classical cryptography boasts of efficient and robust protocols like the Diffie-Hellman key exchange, in the current times, with the advent of quantum computing they are very much vulnerable to eavesdropping and cryptanalytic attacks. Using quantum cryptographic principles, however, these classical encryption algorithms show more promise and a more robust and secure structure for applications. The unique properties of quantum EPR pairs also, on the other hand, go a long way in removing attacks like eavesdropping by their inherent nature of one particle of the pair losing its state if a measurement occurs on the other. The concept of perfect forward secrecy is revisited in this paper to attribute tighter security to the proposed protocol.

The Q2 dependence of dijet cross sections in γp interactions at HERA

Abstract: The dependence of the photon structure on the photon virtuality, Q(2), is studied by measuring the reaction e(+) p --> e(+) + jet + jet + X at photon-proton centre-of-mass energies 134 5.5 GeV in Ihe Final state. The dijet cross section has been measured as a Function of the fractional momentum of the photon participating in the hard process, x(gamma)(OBS). The ratio of the dijet cross section with x(gamma)(OBS) 0.75 decreases as Q(2) increases. The data are compared with the predictions of NLO pQCD and leading-order Monte Carlo programs using various parton distribution functions of the photon. The measurements can be interpreted in terms of a resolved photon component that falls with Q(2) but remains present at values of Q(2) up to 4.5 GeV2. However, none of the models considered gives a good description of the data. (C) 2000 Elsevier Science B.V. All rights reserved.


Numerical Buckling Analysis of Plate Assemblies

Abstract: Determination of the critical stress parameters for local buckling of a plate assembly, such as a cold-formed structural profile or a folded plate structure, involves the solution of an eigenvalue problem of a family of linear partical differential equations. Excepting a few classical cases, numerical methods are required for solution. For the common practical case that the properties are constant in one direction of the plate, a separation of variables method is given which reduces the problem to a one-dimensional iteration and quadratures. Proof of convergence is given. A modification of Newmark's method for buckling analysis is indicated. Examples show rapid convergence, good accuracy, and suitability for manual computation. /Author/

Abstract: One and two magnons Raman scattering was observed in NaNiF3:the results, which include experiments with an applied magnetic field, allow the determination of most of the coefficients describing the magnetic properties: isotropic exchange, antisymmetric exchange, symmetric anisotropic exchange, single ion anisotropy. Temperature dependence is also discussed.


マイクロフィン付き水平管内凝縮の修正理論モデル(熱工学, 内燃機関, 動力など)

Abstract: The previously proposed theoretical models of film condentation in helically grooved, horizontal microfin tubes have been modified to describe the characteristics of condensing two-phase flow more accurately. The stratified flow regime and the annular flow regime were considered. For the stratified flow regime, the previously proposed theoretical model was modified to take account of the curvature of vapor-liquid interface due to the surface tension force. For the annular flow regime, a more accurate expression for the interfacial shear stress was incorporated in the previously proposed theoretical model. Generally, the modified theoretical models predicted a lower circumferential average heat transfer coefficient than the previously proposed ones. Comparison of the theoretical predictions of the circumferential average heat transfer coefficient with available experimental data for six tubes and five refrigerants revealed that a good agreement (r.m.s. error of less than 21.1%) was obtained for all cases when the higher of the two theoretical predictions were adopted as the calculated value.

Estimate of some destabilizing factors influencing a controlled transparency made of yttrium orthoferrite

Abstract: An estimate was obtained of the influence of laser radiation and large-amplitude (1.5 A) current pulses in the presence of a load resistance of the order of 1 Ω on the increase in the temperature of the working medium of a controlled transparency made of yttrium orthoferrite. It was found that when this transparency was operated under normal conditions, the influence of the laser radiation and strong current pulses altered the temperature by 1–2°K. This change in temperature had no significant influence on the magnetooptic characteristics of the working medium of the transparency.


Polarization Effects in Drell-Yan Type Processes h_1+h_2 ->(W,Z,\gamma*,J/psi)+X

Abstract: The measurement of the angular distribution of leptons from the decay of a $W$, $Z$, $\gamma^{\ast}$, or $\Jpsi$ produced at high transverse momentum in hadronic collisions provides a detailed test of the production and decay mechanism of the spin one state. In the absence of cuts on the final state leptons, the lepton angular distribution in the lepton pair rest frame is determined by the polarization of the spin one state. At leading order in perturbative QCD the general structure of the decay lepton distribution arising from a $W,Z [\gamma^{\ast},\Jpsi]$ is controlled by six [four] invariant structure functions. In the presence of cuts, the lepton angular distributions are dominated by kinematic effects rather than polarization effects. We present Monte Carlo studies for Tevatron energies and discuss how polarization effects can be highlighted in the presence of cuts.

Solar Modulation Effects in Terrestrial Production of Carbon-14

Abstract: This paper is concerned with the expected deviations in the production ::: rate of natural 14C on the earth due to changes in solar activity. We review the ::: published estimates of the global production rates of 14C due to galactic and solar cosmic ray particles, and present new estimates of the expected secular variations in 14C production, taking into account the latest information available on galactic ::: cosmic ray modulation and long-term variations in solar activity. Estimated secular variations are related to data on atmospheric 14Cf 12C ratios based ::: on tree rings. It is concluded that the observed higher frequency wiggles in atmospheric 14C/12C ratios occurring with time scales of about two hundred years and of 1 to 2 percent in magnitude (de Vries, 1958; Suess, 1970a,b; 1979; Damon, Lerman, and Long, 1978), are largely due to solar activity dependent modulation of the galactic cosmic ray flux by solar plasma. These variations override a slowly varying sinusoidal ::: change of about 10 percent in magnitude during the last approximately 8000 years, which is believed to be primarily due to changes in the geomagnetic field. The high ::: frequency modulation effect in 14C production is substantial, about 20 percent, which, considering the response function of the atmosphere (cf Houtermans, Suess, and ::: Oeschger, 1973), is adequate to explain the observed 14C wiggles (also named Suess wiggles or de Vries oscillations) if in the past, periods of large modulation effects and also periods of weak modulation persisted, ie, the sun remained both active and inactive over long periods of time, of the order of several decades to centuries. The ::: pioneering investigations of Eddy (1976; 1977) of the ancient records of solar activity make it plausible that the 14C wiggles in the ancient 14C/12C ratios are primarily due to modulation of galactic cosmic ray flux by a varying sun. Thus, the 14C wiggles are good indicators of solar activity in the past. ::: We also present revised estimates of the production rates of 14C on the earth ::: due to solar flare accelerated cosmic rays and limits of direct accretion of 14C on the earth.


Stretched exponential relaxation arising from a continuous sum of exponential decays

Abstract: Stretched exponential relaxation of a quantity n versus time t according to n = n_0 exp[-(lambda* t)^beta] is ubiquitous in many research fields, where lambda* is a characteristic relaxation rate and the stretching exponent beta is in the range 0 < beta < 1. Here we consider systems in which the stretched exponential relaxation arises from the global relaxation of a system containing independently exponentially relaxing species with a probability distribution P(lambda/lambda*,beta) of relaxation rates lambda. We study the properties of P(lambda/lambda*,beta) and their dependence on beta. Physical interpretations of lambda* and beta, derived from consideration of P(lambda/lambda*,beta) and its moments, are discussed.


Metabolic regulation of end product distribution in lactobacilli: Causes and consequences

Abstract: This review examines the regulation of end product distribution in Lactobacillus plantarum and other lactobacilli, the factors that influence this distribution, and the bioenergetic consequences of end product distribution. Similarities to and differences from other genera in the lactic acid bacteria are described. Lactobacilli use many different transport systems to obtain nutrients. Carbohydrates and organic acids are transported in cells by specific phosphoenolpyruvate phosphotransferases (PEP—PTS) or permeases. The carbohydrates are then metabolized to different end products through a common key intermediate, pyruvate. The ability of lactobacilli to produce various end products depends on species, strains, genetic capacity, expression of enzyme activity, sugar structure, and environmental conditions. The regeneration of the NAD+ required for continued glycolysis is a key regulatory factor of end product distribution. The excretion of protons with acidic end products can directly generate a proton motive force and it also contributes to intracellular pH homeostasis. Anionic precursor—product exchange systems can also generate a proton motive force if the exchange is not electroneutral.


Terpenoid indole alkaloid biosynthesis and enzyme activities in two cell lines of Tabernaemontana divaricata

Abstract: Abstract The possible limitation of the rate of biosynthesis of terpenoid indole alkaloids by low enzyme levels was investigated in two cell lines of Tabernaemontana divaricata with different terpenoid indole alkaloid biosynthetic capacities. The activities of tryptophan decarboxylase (TDC), strictosidine synthase (SSS), strictosidine glucosidase (SG), isopentenyl pyrophosphate isomerase (IPP isomerase) and geraniol 10-hydroxylase (G10H) of both cell lines were compared. The activities of TDC, SSS and IPP isomerase did not show a direct relationship with the biosynthetic capacity but SG and G10H might be limiting. In order to test whether the availability of the terpenoid precursor limits the biosynthesis of the terpenoid indole alkaloids, loganin was fed to the cultures. Loganin-feeding did not influence any of the measured enzyme activities but increased the terpenoid indole alkaloid accumulation of both cell lines to similar levels. A five-fold increase was observed for the accumulating line and a more than 100-fold increase for the low-accumulating one. Strictosidine accumulated mainly in the low-accumulating cell line which has high TDC and low SG activity; the amounts and types of the other terpenoid indole alkaloids which accumulated were similar in both lines. From this it can be concluded that the biosynthesis of terpenoid indole alkaloids in both cultures is limited by the availability of terpenoid precursors; this pathway is not saturated with substrates under normal culture conditions.

High frequency of unusual high molecular weight glutenin alleles in 232 tetraploid durum wheat accessions (Triticum turgidumL. ssp.durumDesf)

Abstract: A total of 232 accessions of tetraploid species, durum wheat (Triticum turgidum L. ssp. durum Desf., 2n=4x=28, AABB) with a widespread origin of various countries were used in this study. Their high molecular weight glutenin subunit (HMW-GS) composition was identified by Matrix-assisted laser desorption/ionization time-of-flight Mass Spectrometry (MALDI-TOF-MS). Among all accessions analyzed, 194 were homogeneous for HMW-GS, 38 were heterogeneous, and 62 possessed unusual or new subunits. The results revealed a total of 43 alleles, including 5 at Glu-A1 and 38 at Glu-B1, resulting in 60 different allele combinations. The Glu-B1 locus displayed higher variation compared with Glu-A1. Glu-A1c (55.2%) and Glu-B1aj (17.7%) were the most frequent alleles at Glu-A1 and Glu-B1, respectively. Two allele types (“null” and 1) at the Glu-A1 locus and three allele types (7OE + 8, 14+15, 8) at the Glu-B1 locus appeared to be the common types in the 232 accessions. A total of 23 new alleles represented by unusual subunits were detected at the Glu-A1 and the Glu-B1 locus.

Abundance and population dynamics of Cacopsylla pyri (Hemiptera: Psyllidae) and its potential natural enemies in pear orchards in southern Spain

Abstract: Abstract The abundance and population dynamics of the pear psyllid Cacopsylla pyri L. and its potential natural enemies were followed in pear orchards in southern Spain. The fieldwork was carried out from 2007 to 2010 in two chemically-treated and two non-treated orchards. The abundance of C. pyri gradually decreased through the years in both treated and non-treated orchards, but it reached lower levels in the former than in the latter. In the fourth year of the study the abundance of C. pyri was low in both orchards and the incidence of russet acceptable. Ants, spiders and the mirid Pilophorus gallicus Remane were the most abundant potential natural enemies interacting with C. pyri . The population of these predators progressively increased through the years in treated and non-treated orchards, although, the abundance of natural enemies was higher in the latter. P . gallicus reached high numbers at the same time as C. pyri and was probably responsible for controlling the psyllid outbreak in spring. Ants were abundant and may prey on C. pyri but also protect pear psyllid nymphs in exchange for honeydew. The increase in the number of spiders in summer was associated with a decrease in the number of ants and P. gallicus . Spiders could keep C. pyri at low levels during summer and autumn, which might reduce the number of overwintering adults and subsequent population growth in spring. The overall parasitism rates of C. pyri nymphs were low; Trechnites insidiosus (Crawford) was the only species of parasitoid found, together with the hyperparasitoid Aphidencyrtus mamitus Walker.

Attributes of the seed bank after a century of primary succession on islands in Lake Hjälmaren, Sweden

Abstract: 1 A large number of islands was created when the water table of Lake Hjalmaren, south central Sweden, was lowered between 1882 and 1886. We have complete lists of vascular plant species for 40 of these islands from 1886, 1892, 1903–04, 1927–28 and 1984–85. ::: ::: ::: ::: 2 We have investigated the seed bank on nine of these islands and compared species composition at different soil depths with the species lists from the islands in 1886–1985, and with the present vegetation in the area of seed bank sampling. We have also investigated the distribution in the soil of seeds from species with different ecological attributes, including seed longevity, successional status, seed weight, seed form and species longevity. ::: ::: ::: ::: 3 Seeds in soil samples were allowed to germinate over the course of two summers with an intermediate cold storage. We found 1944 seeds representing 65 taxa. The mean seed density was 84 seeds dm–2. ::: ::: ::: ::: 4 The similarity between the surface soil (0–3 cm) seed bank and the vegetation at the different vegetation analyses increased from 1886 to 1993. The similarity between the present vegetation and the seed bank decreased with increasing soil depth, and the soil at 12–15 cm had no species in common with the present vegetation. Several species now absent from the vegetation were found in the seed bank. ::: ::: ::: ::: 5 Deeply buried seeds came from early successional, annual species with long-term persistent and low-weight seeds, as expected from seed bank theories, but were slightly elongated, which was in contrast to theories. Spherical seeds were associated with the surface soil, as were short-lived and high-weight seeds from late successional, perennial species.

A 96‐well plate assay for the study of calmodulin‐activated Ca2+‐pumping ATPase from red‐cell membranes

Abstract: A simple multi-well assay is described which can be used to assess the activity of the plasma membrane Ca2+ pump in human erythrocytes. The effect on activity of Ca2+, calmodulin, and the two reagents in combination can be quantified through the detection of inorganic phosphate released from ATP. The malachite green assay and a microplate reader are used to measure the concentration of released inorganic phosphate. The experiment can be completed by tertiary level biochemistry students in under 90 min and can stimulate a range of tutorial discussion topics including Ca2+ homeostasis in cells, enzyme structure and kinetics, the role of allosteric effectors and their mechanism of action, protein purification, and data analysis.


New or Rare Mosses of Alabama from the Piedmont and Gulf Coastal Plain

Abstract: Fourteen mosses are added to the flora ofAlabama and 19 are reported for the second time or are otherwise of interest. The reports for mosses from the Piedmont and Gulf Coastal Plain are best found in Mohr (190 1), Reese (1984), and Wilkes (1965). The region was defined by using a physiographic map of Alabama (Sapp & Emplaincourt 1975). The counties best col- lected appear to be: Mobile (Mohr's home), Lee (Auburn University), Pike and Dale (Wilkes' home area), and Tuscaloosa (The University of Alabama). Tuscaloosa county is only partially in the Coastal Plain. The county with the highest number of taxa reported is Mobile with 106 and the least is Wilcox with one. The average number of taxa reported per county is 27. The senior author has examined the mosses deposited at AUA, LAF, UNA, and the Uni- versity of South Alabama. The taxa presented below are from recent collections mainly by the authors or from records of the above herbaria. For a similar


Preliminary investigation of the antibacterial activity of Acalypha hispida leaf extracts against local bacterial isolates from skin infections

Abstract: Acalypha hispida leaf extracts are used locally for the treatment of skin infections. We sought to obtain laboratory-based evidence for this practice by evaluating the antibacterial activity of this extract against local isolates of bacteria obtained from skin lesions and wounds. Aqueous and ethanolic extracts were evaluated using the agar well diffusion method against Staphylococcus aureus , Pseudomonas aeruginosa , Streptococcus pyogenes , Escherichia coli , Klebsiella species, and Salmonella typhimurium . S. aureus (ATCC standard and local) and Ps. Aeruginosa isolates were sensitive to all the extracts but one. E. coli (ATCC standard and local), S. enterica serovar typhimurium and Klebsiella species were only sensitive to the soxhlet leaf extracts while S. pyogenes was sensitive to only the ethanolic soxhlet extract. Though there was no statistically significant difference in the antibacterial activity of the 5-days and 14-days neat extracts obtained by soaking in water (p = 0.13) and ethanol (p = 0.08), their antibacterial activity decreased with longer soaking periods. Likewise, there was no significant difference in the antibacterial activity of the neat water and ethanolic soxhlet extracts (p = 0.48). The results show that A. hispida leaf extracts showed some in vitro antibacterial activity and that aqueous extraction using heat would be the preferred option.

The Effect of Potassium Deficiency on Stomatal and Cuticular Resistance in Tea (Camellia sinensis)

Abstract: The effect of potassium deficiency on cuticular resistance and diurnal variation in stomatal diffusive resistance was studied in tea (Camellia sinensis). The plants were grown in sand and potassium deficiency induced by withholding the supply of potassium. ::: ::: ::: ::: The results showed that during the day potassium-deficient leaves had a higher stomatal diffusive resistance than control leaves. However when solar radiation was reduced by clouds the stomatal diffusive resistance in both control and potassium-deficient leaves was not significantly different. Night opening of stomata was observed in both control and potassium-deficient leaves, but noticeably lower in the latter. Potassium-deficient leaves had a lower cuticular resistance than control leaves.


Gas exchange rate and yield response of strawberry to carbon dioxide enrichment

Abstract: Short-term carbon dioxide (CO2) enrichment (1000 μl 1−1 for 10 days), starting 2 weeks after initial bloom, enhanced the leaf CO2 exchange rate (CER) in rockwool-cultured strawberry (Fragaria × ananassa). CO2 enrichment throughout the fruiting period stimulated canopy CER, decreased chlorophyll and leaf protein loss, and enhanced fruit set and consequent fruit production.


Pectin: A new perspective from the biorefinery standpoint

Abstract: Pectin is a natural product of central importance in the emerging biorefi nery that uses fruit waste as a raw material. Generally obtained from lemon peel or from apple pomace, pectin is mainly used as a thickener and a stabilizer in the food industry. Due to its unique chemical properties and biochemical activity, however, its use is growing in many other sectors. Providing a unifi ed view of the main research and utilization trends, this study identifi es open opportunities toward larger scale production of a valued biopolymer that, we argue, will shortly emerge as a central product of the biorefi nery, and of the citrus-based biorefi nery in particular. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd


Comparison of radiation effects on weight of rabbits after consumption of fresh and thermoxidized palm oil diets

Abstract: This study, investigated the effects of radiation on weight change in rabbit following consumption of diets mixed with fresh and thermoxidised palm oil, common diets among the people in the tropics. Two groups of rabbits each were fed with normal diets (Control group 1), Fresh palm oil diets (FPOD) and thermoxidised palm oil diets (TPOD), respectively, while one batch of each group (Control group 2R, FPOD 2R and TPOD 2R, respectively) were subjected to X-irradiation. Weights of the experimental animals were taken over 12 weeks of feeding, followed by another ten weeks after a break of seven weeks to allow for recovery of the animals. Results showed that FPOD diets produced a weight enhancement effect on the animals, with 14.86% weight increase in 12 weeks of feeding against 13.05% for the control group 1 animals. This reduced after X-irradiation to a weight gain of 8.85% for the control group 2R and 7.08% for the FPOD 2R group. TPOD groups showed poorer weight response at -3.75% for the group 1 and -3.32% for the irradiated group 2R. Repeating the experiments after the rest period showed the same pattern of results but at slightly lower values. The results are statistically significant at P Global Journal of Mathematical Sciences Vol. 6 (1) 2007: pp. 29-34

The Effects of Different Hormones and their doses on Rooting of Stem Cuttings in Anatolian Sage (Salvia Fruticosa Mill.)

Abstract: In this research, three different hormones and five different hormone dosages were applied on cuttings were taken from Anatolian sage plants (Salvia fruticosa Mill.) before flowering period. NAA, IBA (0, 60, 120, 180, 240 ppm) and IAA hormones (0, 100, 200, 300, 400 ppm) were prepared by dissolving in distilled water. Stem cuttings were kept in hormone solution for 24 hours and they were planted in perlit medium under greenhouse conditions. After a month, the number of rooted stem cutting, the number of root per stem cuttings, root length and root weight were determined on stem cuttings. Rooting was observed in all of the cuttings for both samples to which hormone was applied and to which hormone was not applied. According to the result of the variance analysis, the effects of the hormones and hormone doses on the examined characters were found significant as statistically. According to the results obtained, IAA application increased root number considerably. While high hormone dose applications caused the notable increase in root weight and root number in all of three hormones, low hormone applications did not affect root length.

Low-fat Frankfurters with Elevated Levels of Water and Oleic Acid

Abstract: The effects of simultaneous incorporation of maximum allowable levels of water and high-oleic sunflower oil (HOSO) on frankfurter properties were investigated. The formulation changes generally had little effect on processing yield. Frankfurters formulated with HOSO were 180-241% higher in the ratio of total monounsaturated fatty acids to total saturated fatty acids when compared to control products with similar total fat levels. Consumer-panel sensory data and instrumental texture profile data indicated that low-fat (14-16%), high-water, HOSO frankfurters- were as acceptable as control frankfurters with 28% fat (all-animal fat) and did not have the texture problems observed previously with low-fat, HOSO frankfurters without extra added water.

Uniformisation of phytoplankton chlorophyll a and macrophyte biomass to characterise the potential trophic state of shallow lakes

Abstract: Abstract Phytoplankton and macrophytes are the main primary producers in shallow lakes, and lake eutrophication can induce excessive increases in producer productivity and biomass. To create an ecological index, the equivalent chlorophyll a (EC-a) content of phytoplankton and macrophytes was calculated with an uniformisation model of the phytoplankton chlorophyll a and macrophyte biomass, which is very important to analyse the potential trophic state of the ecosystem in shallow lakes. There was competitive balance between phytoplankton and macrophytes in some shallow lakes of Jiangsu province, China. The EC-a did not significantly correlate with trophic state indicators such as the transparency, total phosphorus, total nitrogen and chemical oxygen demand in the studied lakes. No significant correlation appeared between the EC-a and TSI in the three lake groups investigated. The traditional assessment of the trophic state only utilised the biomass of phytoplankton and excluded the biomass of macrophytes in the water column. Thus, the EC-a index is better suited to characterise the potential trophic state of shallow lakes considering the potential impact of macrophytes.

A short hatchery history: does it make a difference to aggressiveness in European grayling?

Abstract: The level of aggressive behaviour in three populations of grayling Thymallus thymallus was lower in the hatchery strains than in the wild strains at the age of 0+ years. Due to similar rearing conditions, genetic divergence of the strains was most likely. As the hatchery fish used were second generation hatchery fish, this suggested that genetic changes in the hatchery can be very rapid. Therefore, it would be beneficial to use the progeny of wild fish for re-introductions. Differences in aggressiveness between the strains still existed at the age of 1+ years, when the strains had been reared under common hatchery conditions for a year. A relatively short period in the hatchery may maintain the original behavioural characteristics of the fish and thus give the best possible basis for survival in the natural environment.


Effect of transient high-energy diets just after ovulation on ovarian performance and metabolic status in cyclic ewes

Abstract: Abstract The aim of this study was to investigate the influence of short-term treatment of high-energy diet after ovulation on ovarian function and metabolic status in ewe. Cycling ewes Ossimi were divided into treatment group (TG; n = 6) and control group (CG; n = 6). After ultrasonographic detection of ovulation (day 0), a high-energy diet (12.55 MJ DE/kg diet; 125% of maintenance) was fed to TG from day 1 to day 4 after ovulation (4 days). The high-energy diet consisted of 850 g concentrate mixture and 150 g alfalfa hay, plus ad libitum access to wheat straw. The CG was offered as maintenance diet (10 MJ DE/kg diet) throughout the experiment. Follicular development was observed ultrasonographically every other day while blood samples were collected daily throughout the experiment for the analysis of glucose, total cholesterol, urea, triglycerides, total proteins, aspartate aminotransferase (AST), alanine transaminase (ALT) and glutamate oxaloacetate transaminase (GOT). Transient feeding of high-energy ration during early luteal phase of estrous cycle significantly influenced the concentration of glucose and some metabolic profiles. Total proteins were greater at first, third and fourth day after ovulation (ovulation is day 0) in TG when compared to CG ewes. Blood glucose concentration was greater in TG than that of CG at days 1, 2, 3 and 4 postovulation. The average number of small follicles (2–2.9 mm) of the first follicular wave after ovulation was greater in TG ewes (23.3 follicles) than that of CG (2.2). There was no difference in the number of medium (3–5 mm) and large sized follicles (>5 mm) between CG and TG ewes. Moreover, the maximum size of large follicles did not differ between CG (5.6 mm) and TG ewes (5.9 mm). In conclusion, high-energy diet may improve number of small follicles and alter energy metabolite during early luteal phase in cycling ewes.


Studies of the post-Glacial History of British vegetation VII. Lake sediments: Pollen diagrams from the bottom deposits of the North Basin of Windermere

Abstract: Eight pollen diagrams from cores lying approximately on an east to west transect across the North Basin of Windermere and macroscopic plant remains identified from these cores are described and figured. The marginal cores show a well-developed late-glacial succession of two layers of barren laminated glacial clay, separated by a detritus silt containing plant remains which indicate a cold-temperate birchwood flora; it is suggested that this succession may be correlated with the Upper and Lower Dryas clays separated by the cold-temperate Allcrod layer of Continental authors. The post-glacial deposits, which are most completely represented in the deep-water cores, show similar phases of forest history to those already recognized in England and Wales, but the apparent over-representation of Pinus in deep-water deposits and the absence of Fagus and Carpinus introduce complications into any attempt to apply to these deposits the zonation scheme worked out for the East Anglian fenland.

PERIDINIUM GREGARIUM, A NEW SPECIES OF DINOFLAGELLATE2

Abstract: SUMMARY ::: ::: A dinoflagellate has been found in tidepools on the coast of the Palos Verdes Peninsula in southern California. It is described as a new species, Peridinium gregarium. In the tidepool habitat, great numbers of the organism form cloud-like masses held together by a mucous matrix. The gregarious cloud formation seems to be shared by only one other species of dinoflagellate, Peridinium sociale (Henneguy ex Labbe) Biecheler, 1935.

A REVISION OF LACK'S BROOD REDUCTION HYPOTHESIS

Abstract: A recent review by T. Amundsen and J. N. Stokland showed that, when food was plentiful, last-hatched nestlings of asynchronously hatched broods died more frequently than their nestmates or nestlings in synchronously hatched broods. They argued that if last-hatched nestlings die as a consequence of hatching asynchrony, then brood reduction must be maladaptive. I construct a model similar to a model by D. M. Temme and E. Charnov. In my model, asynchronously hatched broods experience reduced survival rates of the last-hatched nestling during good food years, and synchronously hatched broods experience entire brood starvation during bad food years. I compare the reproductive performance of parents raising an asynchronously hatched brood to parents raising a synchronously hatched brood. I show that hatching asynchrony is favored over synchronous hatching when good food years are not very frequent, when the survival rate of last-hatched nestlings during good food years is high, when the survival rate of nestlin...

Reproduction in sympatric lizards: comparison of two species of Ctenotus (Scincidae) in south-eastern Australia

Abstract: The scincid lizards Ctenotus robustus and C. taeniolatus occur sympatrically in regenerating, sand-mined areas in the Port Stephens–Myall Lakes region, coastal New South Wales, Australia. They are absent from the unmined open forest of the area. The reproductive characteristics of these two species were compared. Males reached sexual maturity at a smaller snout–vent length (SVL) than females in C. robustus (72 mm v. 78 mm) and C. taeniolatus (49 mm v. 52 mm). Males were reproductive from August to December and maximum testis volume in both species occurred in early spring; minimum testis volume was recorded in early autumn. Females of both species contained yolking follicles or eggs from October to January (spring–summer). Clutch size in C. robustus (4–9) did not differ significantly from that in C. taeniolatus (2–7) when SVL was accounted for. Both species laid eggs in nests dug 4–5 cm deep in open sandy areas with sparse vegetation, and nesting requirements might explain their absence from open forest. At hatching, C. robustus averaged 35.9 mm SVL and C. taeniolatus averaged 29.9 mm SVL. Hatchlings of both species were at field sites from mid-January to early April. Overall, reproductive characteristics of C. robustus and C. taeniolatus were generally similar.


Forward creep grazing of lambs to increase liveweight gain and post‐weaning resistance to endoparasites

Abstract: Abstract An experiment was conducted in New Zealand to assess the effect of creep grazing of lambs on their liveweight and resistance to endoparasites. Comparisons included creep versus non‐creep grazing at two herbage allowances and regular an‐thelmintic drenching. Treatments commenced with 6‐week‐old twin reared lambs, and ceased when they were weaned at 13 weeks, with the exception of the drench treatment which continued post‐weaning. Pastures used contained sheep endoparasites. At 8 weeks post‐weaning one lamb from each twin set was slaughtered, remaining lambs were then drenched, and 8 and 9 days later were orally dosed with 180 Trichostrongylus colubriformis L3/kg liveweight each day (averaging 12 650/lamb). Three weeks later these lambs were also slaughtered. Measurements included liveweight, faecal worm egg count (FEC) and adult endoparasite numbers. Neither herbage allowance nor creep grazing affected FEC or adult endoparasite numbers. Fortnightly drenching of creep grazed lambs on the high allow...

Urinary α-l-fucosidase in cystic fibrosis

Abstract: Abstract The binding of the urinary lysosomal enzyme α- l -fucosidase to free- and Sepharose 4B-bound concanavalin A has been compared in cystic fibrosis (CF) patients and normal controls. The concentration of methyl-α- d -mannoside necessary to prevent 50% of total α- l -fucosidase activity to bind to free and bound concanavalin A (Ki,50%) was similar for CF (0.68 ± 0.20 and 1.3 ± 0.3 mmol/1, respectively) and normal controls (0.53 ±0.18 and 1.9 ± 0.5 mmol/1, respectively). The CF and normal urinary α- l -fucosidase also showed similar pH optima (4.8), Km,app (0.071 and 0.074 mmol/1, respectively) and thermodenaturation curves at 44° C (t 1 2 = 108 min). We report that the kinetic and the concanavalin A-binding affinity of α- l -fucosidase are similar from urine of cystic fibrosis patients and controls.


Factors affecting γ-linolenic acid content in fermented glutinous rice brewed by Rhizopus sp.

Abstract: Abstract Fermented glutinous rice is a popular oriental food brewed by Rhizopus sp. in China. Although Rhizopus sp. Q303 can produce γ -linolenic acid (GLA), GLA content in fermented glutinous rice brewed by Xiaoqu of Rhizopus sp. Q303 greatly varied in terms of brewing temperature, from zero to 1.4±1.1% in total fatty acids, and less than that in mycelia of Rhizopus sp. Q303. This means apart from brewing temperature some other factors must be affecting GLA content in fermented glutinous rice. Further studies showed that fermented glutinous rice inoculated with spores of Rhizopus sp. Q303 contained about double the GLA than those with mycelia (4.3±1.6% compared to 2.2±0.9%). The optimal amount of inoculum was 4.90×10 6 spores/100 g cooked rice. The higher GLA content in the fermented glutinous rice was obtained when using spores as an inoculum from fresh culture before inoculation than that from culture preserved for 8 months in a refrigerator (4.3±1.6% compared to 1.4±0.7%). The optimal temperature for brewing was about 26°C. When the brewing temperature was 11°C, GLA content was no longer detected in fermented glutinous rice. GLA content plateaued between 36 and 60 h during brewing of fermented glutinous rice. Under optimal brewing conditions, GLA content in fermented glutinous rice was over 3 times that of the traditional Xiaoqu brewing process.


Patterns of zonation of assemblages of the Lutjanidae, Lethrinidae and Serranidae (Epinephelinae) within and among mid-shelf and outer-shelf reefs in the central Great Barrier Reef

Abstract: Visual censuses were used to quantify the distribution and abundance of the Lutjanidae, Lethrinidae and Serranidae in three reef zones (windward reef slope, lagoon, back reef) of three reefs on the mid shelf and three reefs on the outer continental shelf in the central region of the Great Barrier Reef. Significant spatial variability was identified in the abundances of many species between locations (outer-shelf and mid-shelf communities), between reefs (high-abundance v. low-abundance reefs), and within reefs (characteristic communities within zones on individual reefs). Species of the Lutjanidae, Lethrinidae and Serranidae were found to occur in assemblages that were characteristic of major zones (windward reef slopes, lagoons and leeward back reefs), this pattern being consistent within and among shelf locations. Care will need to be taken in determining the appropriate spatial scales of sampling in any future experiments (e.g. manipulations of fishing pressure) to ensure that the effects of smaller-scale spatial differences are not confounded when larger-scale comparisons are made.
