Modulation of osmotic adjustment and enzymatic antioxidant profiling in Apera intermedia exposed to salt stress

The effects of salinity on growth, osmotic adjustment, and antioxidative responses were evaluated in Apera intermedia. For this purpose, 30-day-old plants were irrigated every other day with Hoagland nutrient solution containing 0, 150, 300, or 600 mM NaCl for 7 and 14 days. The results showed inhibition of growth, relative growth rate, relative water content, and osmotic potential with increasing NaCl concentration. Increased Na + , Clˉ, and Na + /K + ratio and decreased K + and Ca 2+ were determined with increasing NaCl concentrations. The activities of superoxide dismutase and ascorbate peroxidase were conspicuously enhanced at 150 mM NaCl, but activities of catalase, peroxidase, and NADPH oxidase were reduced in a concentration/time-dependent manner. The highest proline, choline, and glycine betaine accumulation assisted higher osmotic adjustment and maintenance of water status at 150 mM. However, the destructive effects of 300-600 mM were more severe in comparison to lower salinity, depending on the increase of hydrogen peroxide and thiobarbituric acid reactive substances for 14 days. After exposure to 300 and 600 mM, only ascorbate peroxidase and glutathione reductase were induced, but they were not sufficient to scavenge H 2 O 2 .
Geometry-specific scaling of detonation parameters from front curvature

It has previously been asserted that classical detonation curvature theory predicts that the critical diameter and the diameter-effect curve of a cylindrical high-explosive charge should scale with twice the thickness of an analogous two-dimensional explosive slab. The varied agreement of experimental results with this expectation have led some to question the ability of curvature-based concepts to predict detonation propagation in non-ideal explosives. This study addresses such claims by showing that the expected scaling relationship (hereafter referred to d = 2w) is not consistent with curvature-based Detonation Shock Dynamics (DSD) theory.
Observation: Cattle diets on excellent and good condition Chihuahuan desert rangelands

Information is limited on the influence of range condition on cattle diets in the Chihuahuan desert. Botanical composition of cattle diets on Chihuahuan desert ranges in excellent and good condition was studied by microhistological analysis. Cattle feces were analyzed seasonally from fall 1991 through fall 1992. Excellent condition and good condition ranges supported 86% and 72% of the climax vegetation, respectively. Key species in cattle diets on the excellent condition range were black grama (Bouteloua eripoda Torr.) and threeawns (Aristida spp.). On the good condition range the key species were dropseeds (Sporobolus spp.), threeawns and black grama. Total grass and black grama content of cattle diets were greater on the excellent condition range. Seasonal trends occurred in cattle diets on good condition but not on excellent condition range. Low availability of forbs and shrubs explained the high diets similarities among seasons on the excellent condition range. Cattle on good condition range readily used forbs and shrubs when green grass was unavailable. Nitrogen and phosphorus analyses of fecal samples indicated diets were nutritionally superior on the good compared to the excellent condition range. Our research and other studies show consumption of forbs and shrubs permits cattle to maximize their nutritional welfare when grasses are dormant. The excellent condition range in our study had a different(P<0.05) mean grass standing crop (999 kg/ha) across periods compared to on the good condition range (659 kg/ha). Based on our research and other studies excellent condition Chihuahuan desert range maximizes forage quantity for cattle but good condition range appears better from a nutritional standpoint in the spring and early summer. Our research and other studies indicate Chihuahuan desert ranges dominated by black grama are most effectively used in winter while ranges with a high dropseed component are best suited for use in summer and early fall.
On Supremum Distribution of Averaged Deviations of Random Orlicz Processes from the Class

This paper is devoted to investigation of supremum of averaged deviations over some continuous function of a stochastic process from Orlicz space of random variables specified by an Orlicz function from the class Δ. An estimate of distribution of supremum of deviations |X(t) − f(t)| is derived using method of majorizing measures. A special case of sub-Gaussian space of random variables is considered.
Numerical Optimization of Gradient Bandgap Structure for CIGS Solar Cell with ZnS Buffer Layer Using Technology Computer-Aided Design Simulation

The band structure characteristics of a copper indium gallium sulfur selenide (Cu(In 1 –x Ga x )SeS, CIGS) solar cell incorporating a cadmium-free zinc sulfide (ZnS) buffer layer were investigated using technology computer-aided design simulations. Considering the optical/electrical properties that depend on the Ga content, we numerically demonstrated that the front gradient bandgap enhanced the electron movement over the band-offset of the ZnS interface barrier, and the back gradient bandgap generated a back side field, improving electron transport in the CIGS layer; in addition, the short circuit current density ( J SC ) and open circuit voltage ( V OC ) improved. The simulation demonstrated that the conversion efficiency of a double graded bandgap cell is higher than with uniform or normal/reverse gradient cells, and V OC strongly correlated with the average bandgap in the space charge region (SCR) of CIGS. After selecting V OC from the SCR, we optimized the band structure of the CIGS cell with a Cd-free ZnS buffer by evaluating J SC and the fill factor. We demonstrated that the cell efficiency of the fabricated cell was more than 15%, which agrees well with the simulated results. Our numerical method can be used to design high-conversion efficiency CIGS cells with a gradient band structure and Cd-free buffer layer.
A Revision of the Power Approximation for Computing (s, S) Policies

A revision of the Power Approximation for computing (s, S) inventory policies is presented. The revision incorporates modifications which (1) ensure homgeneity in the units chosen to measure demand and (2) ensure the proper limiting behavior of S - s when the variance of demand is extremely small. Computational experience shows that the revision has operating characteristics that are typically within a few percent of optimal, which is nearly as accurate as the original Power Approximation.
RECENT PATENTS ON FAST DISSOLVING TABLETS - A REVIEW

Fast dissolving drug delivery system are the fast rising and highly usual drug delivery system aims to enhance safety and efficacy of drug molecule by formulate a convenient dosage form for administration and to achieve better patient compliance. Fast dissolving tablets (FDT) are those solid dosage forms which put on tongue, disintegrate or dissolve instantaneously, releasing the drug, within one minute without the need of water. These dosage forms are placed in the mouth, allowed to disperse or dissolve in the saliva. Fast dissolving tablets have number of advantages over conventional dosage forms like- ease of administration, enhanced bioavailability etc and due to these advantages the fast dissolving tablets have emerged as an alternative to conventional dosage forms. There are many techniques used in fabrication of FDT such as direct compression, tablet moulding, freeze drying, spray drying, mass extrusion, sublimation etc. Many patented technologies have been developed such as Zydis, Orasolv, Durasolv, Quicksolv, WOWTAB, FlashDose, Lyoc technology etc. The objective of present article is to describe the recent patents on fast dissolving drug delivery system.
A parametric study pf powder holdups in a packed bed under decreasing gas velocity condition

The injection of pulverised coal along with the hot air blast in an iron-making blast furnace has contributed to lower the green house emissions and improve both the stability and productivity of the furnace. However, at high injection rates, some coal in the form of powder accumulates in the lower part of the furnace and obstructs the gas and liquid flows. Therefore, there is an urgent need to understand the physics and aerodynamics of gas-powder flow in such systems to improve the flow conditions. In this article, the flow of gas and fines in a packed bed is studied under decreasing gas velocity as it represents the blast furnace aerodynamics more accurately if it is not being considered as a moving bed reactor. A two-dimensional (2-D) model was developed for this purpose. More specifically, a parametric study is performed to determine the effects of the gas blast velocity, particle size adn powder loading on the powder holdups. Results are presented in terms of fines accumulation area. This work shows the dependency of the powder holdups on the packed bed flow parameters. Keywords: Packed bed, turbulent flow, mathematical modelling, decreasing gas velocity, gas-fines flow, powder holdups.
ACEC2012- IT'S TIME TO TECHNOLOGICAL PEDAGOGICAL REASON

Information Communication and Technology (ICT) using teachers have developed special pedagogical reasoning skills for using ICT in their teaching. Shulman’s (1986, 1987) work on pedagogical reasoning is extended to include technology and the researcher proposes that this special process should be termed Technological Pedagogical Reasoning (TPR). This study has looked into the reasoning processes of ICT using teachers across the career stages as defined in the National Professional Standards (Australian Institute for Teaching and School Leadership, 2011) and attempts to answer - How do teachers technological pedagogical reason across career stages and what influences teachers in developing their technological pedagogical reasoning? This research will provide rich description of how TPR is developed and evolves over a teacher’s career. The purpose of this design is to reveal the voices of teachers to determine how they develop TPR in their lesson planning and practice. The study involved collecting data using video stimulated and thinks aloud protocols on their lesson planning and lesson delivery. This data has been analyzed using the thematic analysis with constant comparative method to identify themes. This paper outlines this research project, with a brief introduction to the preliminary results from this study. Further results will be presented at the conference.
COMPACT RADIO SOURCES WITHIN 30″ OF SGR A*: PROPER MOTIONS, STELLAR WINDS, AND THE ACCRETION RATE ONTO SGR A*

Recent broadband 34 and 44 GHz radio continuum observations of the Galactic center have revealed 41 massive stars identified with near-IR (NIR) counterparts, as well as 44 proplyd candidates within 30″ of Sgr A*. Radio observations obtained in 2011 and 2014 have been used to derive proper motions of eight young stars near Sgr A*. The accuracy of proper motion estimates based on NIR observations by Lu et al. and Paumard et al. have been investigated by using their proper motions to predict the 2014 epoch positions of NIR stars and comparing the predicted positions with those of radio counterparts in the 2014 radio observations. Predicted positions from Lu et al. show an rms scatter of 6 mas relative to the radio positions, while those from Paumard et al. show rms residuals of 20 mas. We also determine the mass-loss rates of 11 radio stars, finding rates that are on average ∼2 times smaller than those determined from model atmosphere calculations and NIR data. Clumpiness of ionized winds would reduce the mass loss rate of WR and O stars by additional factors of 3 and 10, respectively. One important implication of this is a reduction in the expected mass accretion rate onto Sgr A* from stellar winds by nearly an order of magnitude to a value of a few × 10 − 7 ? > M ⊙ ? > yr−1. Finally, we present the positions of 318 compact radio sources within 30″ of Sgr A*, 45 of which have stellar counterparts in the NIR Ks (2.18 μm) and L′ (3.8 μm) bands.
A Review of Anisotropic Polar Ice Models : from Crystal to Ice-Sheet Flow Models

The ice single crystal is one of the most anisotropic natural materials and the resulting viscous behaviour of polycrystalline ice can also be strongly anisotropic and is a function of the distribution of the crystal c-axis orientations, i.e. its fabric. Such a strong and strain-dependant anisotropy of the ice polycrystal certainly affects the general flow of polar ice. The aim of this paper is to present an exhaustive overview of most of the glaciological efforts made from more than two decades to account for polar ice anisotropy in ice flow modelling, from the crystal to the ice-sheets scale. We first recall the deformation and recrystallization processes occurring within ice-sheets and their respective effect on the polar ice textures. Then, the different models developed to describe the behaviour of the ice crystal and the polycrystal are presented, with a special emphasis on homogenization methods and fabric description. Finally, existing anisotropic ice flow models and their applications are reviewed.
Receptivity mechanisms in three-dimensional boundary-layer flows

Receptivity in three-dimensional boundary-layer flow to localized surface roughness and free-stream vorticity is studied. A boundary layer of Falkner–Skan–Cooke type with favourable pressure gradient is considered to model the flow slightly downstream of a swept-wing leading edge. In this region, stationary and travelling crossflow instability dominates over other instability types. Three scenarios are investigated: the presence of low-amplitude chordwise localized, spanwise periodic roughness elements on the plate, the impingement of a weak vortical free-stream mode on the boundary layer and the combination of both disturbance sources. Three receptivity mechanisms are identified: steady receptivity to roughness, unsteady receptivity to free-stream vorticity and unsteady receptivity to vortical modes scattered at the roughness. Both roughness and vortical modes provide efficient direct receptivity mechanisms for stationary and travelling crossflow instabilities. We find that stationary crossflow modes dominate for free-stream turbulence below a level of about 0.5%, whereas higher turbulence levels will promote the unsteady receptivity mechanism. Under the assumption of small amplitudes of the roughness and the free-stream disturbance, the unsteady receptivity process due to scattering of free-stream vorticity at the roughness has been found to give small initial disturbance amplitudes in comparison to the direct mechanism for free-stream modes. However, in many environments free-stream vorticity and roughness may excite interacting unstable stationary and travelling crossflow waves. This nonlinear process may rapidly lead to large disturbance amplitudes and promote transition to turbulence.
Compressed Sensing Prototype for Flexible Wireless System

Compressed sensing is recently developed technology which directly compresses sparse data with the sub-Nyquist rate information. It can be considered as ﬁnding a solution of an ill-posed inverse problem of the sparse data. The introduction of recent trends and achievements of compressed sensing including the stmctured compressed sensing and 1-bit compressed sensing will be given for the comprehensive understanding in this paper. Flexible wireless system is a uniﬁed wireless platform composed of ﬂexible access points and a ﬂexible signal processing unit. The goal of a ﬂexible access system is the provision of a uniﬁed wireless platform which has the capability of receiving various types of wireless signals regardless of their signal type. By transferring whole wireless signal data through a wired access line, various types of wireless signals are processed at ﬂexible access points. We implemented a prototype of ﬂexible wireless system in which compressed sensing is used as a radio wave compression method. This paper also introduces ﬂexible wireless system prototype implemented using compressed sensing technology.
EXPLICIT STAGGERED SCHEMES FOR THE COMPRESSIBLE EULER EQUATIONS

We review in this paper an explicit scheme for the numerical simulation of inviscid com- pressible flows; we analyze it for both the barotropic Euler equations and the full Euler equations for an ideal gas. In each case, we summarize the theoretical results that were recently obtained concerning the stability and consistency of the schemes and present some numerical results which confirm their good performance.
A New Communication System : Invisible Blog Attaching Blog Messages to Physical Objects

This paper describes the new communication system named “Invisible Blog System (IBS)”. IBS enables users to attach their blog messages to physical objects and/or scenic locations. Another user that visits the scenic locations to which one or more IBS messages are attached, can access the messages. The main technological issues in realizing IBS are; how to identify the scenic locations and/or objects and so embed the IBS messages and how to browse them. This paper focuses on the first point and proposes a location identification method. The method utilizes RGB scalar-quantized histograms as a feature vector. Location identification experiments are performed at 20 sites. The identification rate is over 96% on average which confirms that the proposed method is valid and effective.

International Conference on Education and Educational Psychology ( ICEEPSY 2012 ) Implementation Process of an Approach for Teaching Mathematics in Elementary School

In 1987 a teacher that work in special school in Ticino (the Italian speaking part of Switzerland) to teach his students mathematics build an approach; it has been disseminated for 20 year in most of the Ticino primary schools. The aim of this study is to explore the implementation procedures and describe the process. The diffusion and opposition to the approach, seem to be connected mainly to the communication and less to an evaluation of the costs & benefits ratio. The strong promoter personal involvement had driven other subjects to overlap promoters and innovation itself (with positive and negative
The Pursuit of Happiness? Subjective Wellbeing and Internal Migration in Great Britain

In 2011 the UK government announced future plans to use subjective wellbeing as a measure of economic success. Understanding both the individual and geographic determinants of subjective wellbeing is important for future policy makers. Internal migration has important impacts on the geographic composition of populations, and if found to impact on individual wellbeing; could have significant effects on geographical variations in wellbeing. The effect of internal migration on individuals has largely been focussed in the labour literature, assessing employment and earnings changes with migration. This paper is the first study to assess the effects of internal migration on subjective wellbeing in Great Britain. We use nationally representative data from the first eighteen waves (1991-2008) of the British Household Panel Survey. The panel structure of the data is ideal for migration analysis, and the data contains a wide range of personal, labour market, and health characteristics of respondents. Migration is measured as movements in residence of 10km or more. Wellbeing is measured as a binary indicator for poor wellbeing, ‘caseness’, using the 12-point version of the General Health Questionnaire with scores of three or more used as indicators for poor subjective wellbeing. The effects of migration on the probability of caseness are measured in the year following a move. Migrants are modelled by motive for moving, and past caseness state. The methodology controls for the potential endogeneity of the migration decision and potential correlation between unobserved heterogeneity and the covariates. The results suggest the effects of migration do not differ by motive, but do differ by past health status. Internal migration could have important impacts on geographic inequalities in wellbeing.
