Pharmacognostic study and establishment of quality parameters of Jatropha gossypiifolia L

Objectives: Today complicated modern research tools for evaluation of the plant drugs are available but microscopic method is one of the simplest and cheapest methods to start with for establishing the correct identity of the source materials. Material and Methods: Pharmacognostic investigation of leaf and stem of Jatropha gossypiifolia Linn. was carried out to determine its macro and microscopic characters. Physicochemical analysis which included parameter like loss on drying, total ash, water soluble ash, acid insoluble ash, sulphated ash, extractive values in different solvents like (petroleum ether, toluene, ethyl acetate, methanol and water) was done. Qualitative phytochemcial analysis and fluorescence analysis was also done. Results: The leaves possessed a cordate base, sariated glandular margine, sub-acute apex and both surfaces were very rough with rigid hairs on surface. Internally, it showed presence of anomocytic stomata, epidermis, parenchymatous tissue, secretary glands, cluster crystals of calcium oxalate, simple starch grains, glandular and simple covering trichomes scattered as such throughout or attached with the cells of the epidermis. Majority of the glandular trichomes were with 4 to 5 celled uniseriate stalk from petiole region. Phytochemical analysis of the powder revealed the presence of different phytoconstituents like alkaloids, tannins, saponins, phlobatanins, triterpenes and flavonoids; phlobatanins and triterpenes were present in maximum amount. In physicochemical analysis, all the parameters were present within the limits. Maximum extractive value was in polar solvent methanol and water. Conclusion: The pharmacognostic characters laid down in the present study will work as a tool for identification and standardization parameters of the drug in the crude form and also distinguish the drug from its adulterants.
Doubly penalized kernel method for heteroscedastic autoregressive datay

We also present the model selection method which employs the cross validation techniques for choosing the hyper-parameters which aect the performance of proposed method. Simulated examples are provided to indicate the usefulness of proposed method for the estimation of mean and variance functions.
Epifluorescent imaging study of the effect of anti-diabetic drug metformin on colorectal cancer cell lines in vitro

Metformin, a widely used anti-diabetic drug, has recently been associated with inhibition of cell proliferation in multiple cancers. However, it is not clear if the reduction in proliferation on treatment with metformin is a result of cell death or slowdown in the rate of growth of cancer cells, because cell viability assays measure only the number of cells at the beginning and end of the experiment. The aim of this study is to utilize a fluorescent imaging technique to directly follow cell death overtime in order to investigate the effect of metformin on colorectal cancer cells HCT116 and SW480. Epifluorescent imaging analysis carried out using ImageXpress Micro XLS High-Content Imaging System show that there is no significant change in cell death observed in the cancer cell lines, as compared to the control, over multiple closely spaced time points, suggesting that metformin in pharmacological doses may not be an effective inducer of cell death in these colon cancer cell lines.
Works Title Persistent Hemispheric Differences in the Perceptual Selection of Spatial Frequencies Permalink

■ Previous research has shown that the right hemisphere processes low spatial frequencies more efficiently than the left hemisphere, which preferentially processes high spatial frequencies. These studies have typically measured RTs to single, briefly flashed gratings and/or have directed observers to attend to a particular spatial frequency immediately before making a judgment about a subsequently presented stimulus. Thus, it is unclear whether the hemispheres differ in perceptual selection from multiple spatial frequencies that are simultaneously present in the environment, without bias from selective attention. Moreover, the time course of hemispheric asymmetry in spatial frequency processing is unknown. We addressed both of these questions with binocular rivalry, a measure of perceptual selection from competing alternatives over time. Participants viewed a pair of rivalrous orthogonal gratings with different spatial frequencies, presented either to the left or right of central fixation, and continuously reported which grating they perceived. At the beginning of a trial, the low spatial frequency grating was perceptually selected more often when presented in the left hemifield (right hemisphere) than in the right hemifield (left hemisphere), whereas the high spatial frequency grating showed the opposite pattern of results. This hemispheric asymmetry in perceptual selection persisted for the entire 30-sec stimulus presentation, continuing long after stimulus onset. These results indicate stable differences in the resolution of ambiguity across spatial locations and demonstrate the importance of considering sustained differences in perceptual selection across space when characterizing conscious representations of complex scenes. ■
Species distribution in the hill dipterocarp forest in Peninsular Malaysia as affected by soil nutrients.

Introduction Shorea cunisii (Seraya) is the major timber species in Peninsular Malaysia and is also the indicator tree species in the hill dipterocarp forest. The latter forest is the major resource base for the wood-based industry with sawn logs placed third behind petroleum and oil palm in the 1998 export of primary c? mmodities. Post-harvest regeneration in the fragile hill dipterocarp forest stand is increasingly of concern in its management. Knowledge on Seraya's response to the influence ~f s.oiInutrients, as reflected in its topographic distribution, is limited. Such information should be useful in assisting its regeneration since a major portion of disturbance in the post-F hill dipterocarp forest stand concerns the mineral soil. In this study Seraya's responses to soil nutrients were compared with that of S. leprosula (Ternbaga) which represents the normative lowland dipterocarp timber species. Both species have overlapping distribution at the lower elevation of the hill forest.
R&D Races and Spillovers between the EU and the US: Some Causal Evidence

This paper examines the relationships between the R&D sector activities of the EU and the US using multivariate Granger-causality tests. The multivariate framework employed also allows us to make causal inferences about the effects of R&D activity on labour productivity in the home and foreign country. As a novelty, we employ the subset transfer function methodology to account for the possibility of "dry holes" in the effects of R&D efforts on economic activity. Our estimation results indicate that R&D activity in the EU is a direct Granger-cause of both R&D and labour productivity in the US, and the effects are negative. On the other hand, the EU reacts positively to increases in R&D productivity in the US. These findings are largely in line with the actual developments in the productivity differentials between the EU and the US and the patterns in their relative shares in the world market for high tech exports.
Empirical Analysis of the Financial Behavior of Investors with Brand Approach (Case Study: Tehran Stock Exchange)

Abstract Behavioral science in the field of finance and investment is among new topics raised in recent years. The relationship between financial sciences and other fields of social sciences such as financial psychology has caused researchers to do many researches regarding the behavior of investors in the financial markets and their reactions to different situations. Based on the theories of financial behavior, shareholders' decision to buy and sell stocks is under the influence of internal and external psychological factors. Through designing and experimental testing of the model of investors' financial behavior in the Tehran Stock Exchange with an emphasis on brand, this study was an attempt to investigate the influence of these factors. To this end, financial, psychological and social factors were considered as the most important external factors influencing the behavior of investors and, considering the mediating role of brand awareness, their impact on perceived risk and perceived return as well as investment intention was tested. The research population consisted of all individual investors in the Tehran Stock Exchange. In order to determine the sample size, considering unlimited population, Cochran formula was used and hence the sample size was determined to be 145. For data collection, standard questionnaire was used. Confirmatory factor analysis was used to test the reliability of the questionnaire and the research hypotheses were tested using path analysis. The results showed that psychological factors have a positive impact on perceived risk and returns. Financial factors had a positive impact on perceived risk but no impact on perceived return. The impact of social factors on perceived risk and perceived return was not confirmed. Moreover, the results showed that brand awareness has a moderating role in the relationship between social factors and perceived risk and return. However, its moderating role was not confirmed in the relationship between the psychological and financial factors and perceived risk and return. Perceived risk had a positive effect on attitude toward the brand. However, the impact of perceived return on attitude toward the brand was not significant. Finally, the attitude toward the brand had a positive effect on shareholders' investment intention.

Large Eddy Simulation of the water flow around a cylindrical pier mounted in a flat and fixed bed

In the present work, a numerical model based upon the Large Eddy Simulation approach has been set up for predicting the three-dimensional flow around a cylindrical pier, mounted on a flat and fixed bed, a generic case that is relevant for the study of flow and scour around bridge piers. This turbulent flow configuration was studied experimentally by Nogueira et al. (2008) with Particle Image Velocimetry (PIV). The main goal of this paper is a first validation of the numerical model, based upon the available data. The numerical tool is capable to qualitatively reproduce the characteristic flow features around the pier, like e.g. the horseshoe vortex system and the vortex shedding in the wake. The predicted extent of the initial scour hole, based upon the bed shear stress magnitudes, agrees well with the observations at the onset of the souring process during the lab experiments. Further quantitative validation of the numerical model will benefit from additional measurement efforts in the experiments.
Technology Di ff erences and Capital Flows ∗

The one-to-one mapping between cross-country differences in capital returns and the direction of international capital flows is broken in a multi-sector world where international factor price differences are driven by technology differences. A technology-backward or low-return-to-capital country will face capital inflows or outflows after financial integration depending on whether no-tradable demand is boosted or not.
Design of Forward Adaptive Piecewise Uniform Scalar Quantizer with Optimized Reproduction Level Distribution per Segments

The problem we address in this paper is the design of nearly optimal scalar quantizer in a wide variance range of the Laplacian input signals, using the piecewise uniform quantizers while restricting the class of quantizers to be forward adaptive. Particularly, the design procedure of the piecewise uniform quantizer with an equidistant support region partion and the optimized reproduction level distribution per segments is presented along with the design procedure of its forward adaptive version. Reproduction level optimization is performed by optimizing the granular distortion of the proposed quantizer using the method of the Lagrange multipliers. For the proposed model we study the influence of the segment number on the SQNR, as well as the SQNR robustness in a wide variance range. Since the results obtained for the assumed Laplacian distribution indicate the SQNR improvement over the G.711 standard, one can expect that the proposed quantizer will be effective in the quantization of signals having the same distribution and the time varying characteristics.

It was found that both psychological distress and maladaptive perfectionism were found at medium level, whereas trait emotional intelligence was found at the high level, Moreover it was found that trait emotional intelligence as a mediator affects the psychological distress- maladaptive perfectionism relationship.
Shelf‐Life Extension of American Fresh Ginseng by Controlled Atmosphere Storage and Modified Atmosphere Packaging

American ginseng roots were treated with an antimicrobial agent, and stored under various CA (2, 5, and 8% CO 2 ) or MA conditions to extend the shelf-life. Changes in respiration rates during CA storage, gas composition in packages, saponin and free sugar content, and other quality factors were monitored during storage. The respiration rate of ginseng increased rapidly during the first month of high CO 2 CA storage and then slowly decreased to stable levels after 3 mo storage. In MA studies, the equilibrium CO 2 concentration was attained after 20 days. There were no noticeable changes In appearance, saponin content and free sugars after 3 mo CA (5% CO 2) storage and MA packages.
Thidiazuron Induces High Frequency Direct Somatic Embryogenesis Growth from Cotyledon Culture of Eurycoma longifolia (Tidiazuron Merangsang Pertumbuhan Somatik Embriogenesis daripada Kultur Kotiledon Eurycoma longifolia)

Eurycoma longifolia is one of the well-known herbal plants in Southeast Asian region due to its remarkable properties, especially the root part that can be used as aphrodisiac, anti-cancer, anti-malaria and anti-ulcer agent. Uncontrolled harvesting of this plant has reduced its population. Thus, an efficient protocol involving the induction of direct somatic embryogenesis from cotyledon culture of E. longifolia has been developed. 15% explants forming embryos were achieved on Modified Murashige and Skoog’s ( MMS) medium supplemented with 0.1 mg/L zeatin plus 0.2 mg/L indole-3-butyric acid (IBA). However, the addition of 0.12 mg/L thidiazuron (TDZ) has increased the percentage up to 22.0%. The maturation phase occurred in the same medium, thus decreased the frequency of subculture and the genetic instability of the embryos. Secondary somatic embryogenesis growth of 20%, which was the highest percentage of growth, was achieved from the primary embryos that were cultured in the MMS medium with the treatment of 2.0 mg/L IBA plus 0.075 mg/L TDZ. The results indicated that the direct somatic embryogenesis obtained can be further used to develop a protocol for plantlet regeneration of E. longifolia.

Isogeometric Implementation of the High-Order Microplane Model for Softening and Localization

In this study, a recently developed higher order microplane (HOM) model for softening and localization, is numerically implemented within a finite element framework based on isogeometric analysis. The HOM model was derived directly from a three dimensional discrete particle model and it was shown to be associated with a high order continuum characterized by independent rotation and displacement fields. Furthermore HOM model was demonstrated to possess two characteristic lengths: the first associated with the spacing of flaws in the material internal structure and related to the gradient character of the continuum; and the second associated with the size of these flaws and related to the micropolar character of the continuum. The displacement-based finite element implementation of this type of continua requires C-continuity both within the elements and at the element boundaries. This motivated the implementation of the concept of isogeometric analysis which ensures a higher degree of smoothness and continuity. NURBS based isogeometric elements were implemented in a 3D setting and with both displacement and rotational degrees of freedom at each control point. The performed numerical analyses demonstrate the effectiveness of the proposed HOM model implementation to ensure optimal convergence in both elastic and softening regime. Particularly, the proposed approach prevents strain localization and spurious mesh sensitivity known to be pathological issues for typical local strain-softening constitutive equations.

A preliminary study on the potential use of an alternative bait for demersal longline fishery; Sepietta sp.

Abstract: : This study was carried out between September 2007 and April 2008 in the Aegean Sea with an experimental longline. Traditional baits such as Sardina pilchardus and Solen vagina were used with Sepietta sp. which is a discarded species from Aegean Sea demersal trawl fishery. 438 individuals belonging to 6 families were obtained and they totally weighed 43.1 kg. It was determined that almost half of the specimens were captured by Sepietta sp. Furthermore individuals caught by this alternative bait composed 45% of the total catch in terms of weight. Results showed that Sepietta sp. was the most efficient bait among all baits used in the study. The use of this species as a bait in longline fishery has also another importance from the perspective of evaluating a trawl discarded species. Keywords: Longline, bait, Sepietta sp. , small scale fishery
Photon-assisted entanglement creation by minimum-error generalized quantum measurements in the strong-coupling regime

We explore the possibilities of entangling two distant material qubits with the help of an optical radiation field in the regime of strong quantum electrodynamical couplingwith almost resonant interaction. For this purpose the optimum generalized field measurements are determined which are capable of preparing a two-qubit Bell state by postselection with minimum error. It is demonstrated that in the strong-coupling regime some of the recently found limitations of the nonresonant weak-coupling regime can be circumvented successfully due to characteristic quantum electrodynamical quantum interference effects. In particular, in the absence of photon loss it is possible to postselect two-qubit Bell states with fidelities close to unity by a proper choice of the relevant interaction time. Even in the presence of photon loss this strong-coupling regime offers interesting perspectives for creating spatially well-separated Bell pairs with high fidelities, high success probabilities, and high repetition rates which are relevant for future realizations of quantum repeaters.
Computer modeling of electrical performance of detonators

An empirical model of detonator electrical performance which describes the resistance of the exploding bridgewire (EBW) or exploding foil initiator (EFI or slapper) as a function of energy, deposition will be described. This model features many parameters that can be adjusted to obtain a close fit to experimental data. This has been demonstrated using recent experimental data taken with the cable discharge system located at Sandia National Laboratories. This paper will be a continuation of the paper entitled ``Cable Discharge System for Fundamental Detonator Studies`` presented at the 2nd NASA/DOD/DOE Pyrotechnic Workshop.
