Evaluation of Antinociceptive and Anti-inflammatory Activity of Leaves of Cassia grandis Linn .

The aim of the present study was to evaluate the antinociceptive and anti-inflammatory activity of the methanolic extract of leaves of Cassia grandis (MECG). The analgesic activity of the extract was evaluated for its central and peripheral pharmacological actions using Eddy's hotplate method and acetic acid-induced writhing respectively. The antiinflammatory activity was evaluated by using Digital plethysmometer (UGO Basil, Italy 7140). The study was carried out using dose of 100 mg/kg p.o. The pharmacological screening of the extract showed significant analgesic activity with good anti-inflammatory profile.
An Approach to Extract Feature using MFCC

Speech is the most natural and efficient way of communication between humans. Lots of efforts have been made to develop a human computer interface so that one can easily interact and communicate in an unskilled way. Speech recognition systems find their applications in our daily lives and have huge benefits for those who are suffering from some kind of disabilities. This paper presents an approach to extract features from speech signal of spoken words using the Mel-Scale Frequency Cepstral Coefficients . It is a nonparametric frequency domain approach which is based on human auditory perception system. Firstly, all the voice samples of isolated words are taken as the input and by using praat tool denoise all these samples. Then coefficients are extracted by using MFCC as these coefficients collectively represent the short term power spectrum of sound. All this implementation is build in Matlab.

Learning about compact binary merger: The Interplay between numerical relativity and gravitational-wave astronomy

Activities in data analysis and numerical simulation of gravitational waves have to date largely proceeded independently. In this work we study how waveforms obtained from numerical simulations could be effectively used within the data analysis effort to search for gravitational waves from black hole binaries. To this end we analyze the cross-correlation between different numerical waveforms weighted by the detector's noise. This allow us to propose measures to quantify the accuracy of numerical waveforms for the purpose of data analysis, study how sensitive the analysis is to errors in the waveforms, and propose a way to efficiently encode the waveform's information for its use as a member of the template bank. We estimate that {approx}100 templates (and {approx}10 simulations with different mass ratios) are needed to detect waves from nonspinning binary black holes with total masses in the range 100M{sub {center_dot}}{<=}M{<=}400M{sub {center_dot}} using initial LIGO. Of course, many more simulation runs will be needed to confirm that the correct physics is captured in the numerical evolutions. From this perspective, we also discuss sources of systematic errors in numerical waveform extraction and provide order of magnitude estimates for the computational cost of simulations that could be used to estimate the costmore » of parameter space surveys. Finally, we discuss what information from near-future numerical simulations of compact binary systems would be most useful for enhancing the detectability of such events with contemporary gravitational-wave detectors and emphasize the role of numerical simulations for the interpretation of eventual gravitational-wave observations. « less

Effect of Oxidative Stress on Secretory Function in Salivary Gland Cells

Reactive oxygen species (ROS) such as superoxide radical anion, singlet oxygen, hydrogen peroxide and hydroxyl radical are products of oxidative metabolism (Kourie, 1998). Low levels of ROS contribute to important signaling pathways to regulate key biological responses, including cell migration, mitosis and apoptosis (Goldschmidt-Clermont & Moldovan, 1999). For instance, endogenous oxidants protected the vasculature by inhibiting endothelial exocytosis that would otherwise lead to vascular inflammation and thrombosis, because endogenous hydrogen peroxide inhibited thrombin-induced exocytosis of granules from endothelial cells (Matsushita et al., 2005). In rat aortic smooth muscle cells, reduction in the intracellular concentration of hydrogen peroxide by the overexpression of catalase within cellular peroxisomes resulted in suppression of DNA synthesis and cell proliferation, and induction of apoptotic cell death (Brown et al., 1999). On the other hand, ROS are known to be pathogenic factors that induce cellular alterations in different cell types. For example, ROS are considered to be involved in the pathogenesis of postischemic endothelial dysfunction, because hydrogen peroxide induces Ca2+ oscillations in human aortic endothelial cells (Hu et al., 1998). In pancreatic ┚ cells, hydrogen peroxide interferences glucose metabolism, which leads to the inhibition of insulin secretion (Krippeit-Drews et al., 1999). In mesangial cells, hydrogen peroxide disturbs Ca2+ mobilization, which is considered to be involved in renal injury (Meyer et al., 1996). In neurons, hydrogen peroxide induces apoptotic cell death (Whittemore et al., 1995).
Gender and the Social Rights of Citizenship: The Comparative Analysis of Gender Relations and Welfare States

State social provision affects women's material situations, shapes gender relationships, structures political conflict and participation, and contributes to the formation and mobilization of identities and interests. Mainstream comparative research has neglected gender, while most feminist research on the welfare state has not been systematically comparative. I develop a conceptual framework for analyzing the gender content of social provision that draws on feminist and mainstream work. Three dimensions of qualitative variation suggested by power resources analysts are reconstructed to incorporate gender: (1) the state-market relations dimension is extended to consider the ways countries organize the provision of welfare through families as well as through states and markets; it is then termed the state-market-family relations dimension; (2) the stratification dimension is expanded to consider the effects of social provision by the state on gender relations, especially the treatment of paid and unpaid labor; (3) the social citizenship rights/decommodification dimension is criticizedfor implicit assumptions about the sexual division of caring and domestic labor and for ignoring the differential effects on men and women of benefits that decommodify labor Two additional dimensions are proposed to capture the effects of state social provision on gender relations: access to paid work and capacity to form and maintain an autonomous household.

© 2018 CEUR-WS. All Rights Reserved. We consider the transformation of propositional linear time temporal logic formulae into a clause normal form, called Separated Normal Form, suitable for resolution calculi. In particular, we investigate the effect of applying various pre-processing techniques on characteristics of the normal form and determine the best combination of techniques on a large collection of benchmark formulae.
Large volume injection in capillary GC using PTV injectors: Comparison of inertness of packing materials

Programmed temperature vaporizing injectors (PTV) have been shown to be eminently suited for large volume sample introduction in capillary gas chromatography [ 1-31. Large volume injection can be applied in trace analysis to improve analyte detectability. Very often it can replace an off-line evaporation step carried out to concentrate a diluted sample extract. In a recent paper we demonstrated that, for sample volumes up to 150 pl, the procedure for large volume injection is very simple when using PTV injectors equipped with liners with internal diameters larger than ca 2.5 mm [4]. With the split valve open and at a liner temperature below the solvent boiling point the sample can be rapidly injected, either manually or with an autosampler equipped with a large volume syringe. The solvent is vented via the split exit while the analytes are retained in the liner. After the solvent elimination step the analytes are transferred to the column in the splitless mode.
Exact Kohn-Sham Density Functional Theory on a Lattice

We formulate a set of equations that facilitate an exact numerical solution of the Kohn-Sham potential for a finite Hubbard chain with nearest neighbour hopping and arbitrary site potentials. The approach relies on a mapping of the non-interacting Kohn-Sham ground state wave function onto the exact interacting system wavefunction and two interconnected self-consistent cycles. The self-consistent cycles are performed within the framework of the Kohn-Sham non-interacting system without any direct reference to the interacting system. The first self-consistent cycle updates the mapping of the non-interacting wavefunction onto the interacting wavefunction based on a trial input density, while the second self-consistent cycle updates the Kohn-Sham potential to yield the trial density. At the solution point, the exact density, the exact Kohn-Sham potential, the density functional correlation energy and the exact interacting system ground state energy are available.
The effect of occupant posture on the risk of fracture in the human tibia under dynamic impact loading

Vehicle floor intrusion is a common cause of injury to the lower leg in automotive collisions. For the most part, experimental investigations into the fracture tolerance of the leg in these collisions have assumed that a vehicle occupant is seated in an idealized neutral posture, with force directed along the long axis of the leg (producing pure compression). This neglects the non-standard postures an occupant may actually assume during a crash, which result in bending in addition to compression. A new injury criterion that accounts for these non-standard postures and the associated combined loading is needed in order to better assess risk and evaluate protective measures in collision scenarios. A custom-built apparatus was used to deliver impulses representative of automotive collisions to eight isolated human tibiae (four pairs, female, aged 48-73). Impacts were delivered at an average velocity of 6 m/s and over an average duration of 23 ms, in order to represent realistic conditions of a frontal collision. The mass of the impacting projectile (and correspondingly impact energy) was increased until fracture was achieved. One specimen from each pair was held at a posture of 15° from pure axial loading and the contralateral at 30°. Forces, moments, and impulse were collected from the tests and analyzed after fracture to determine the effect of posture on injury risk. It was found that specimens held at the smaller angle tended to withstand higher resultant forces applied to the bone before fracture, and that the Revised Tibia Index (RTI) in its current formulation was not reliably able to predict fracture. This work to quantify the effects of leg posture on injury risk will lead to the development of more comprehensive design criteria for vehicle occupant protection measures.
A PRELIMINARY STUDY ON DEVELOPING COLLAGEN SHEET AS BIOMATERIAL USING ACID SOLUBLE COLLAGEN EXTRACTED FROM CHICKEN SKIN

Collagen a fibrous structural protein can be resorbed into the body, a non-toxic and biocompatible, generates only minimal immune response (low antigenicity), and was excellent source for attachment, biological interaction with cells (biocompatibility) and proteolytic degradation pathway (Pati et al., 2012). Collagen has been extracted from by-products of food animals such as cattle, pig as well as marine sources which have been widely used in food, pharmaceuticals and cosmetic industries.In India, large amount of chicken skin are generated as by-product during poultry meat processing. Avian collagen is considered as alternative source for various skin care and medical application instead of conventional bovine and porcine and aquatic collagen (Lin et al., 2013). The present day consumers are more health conscious most of them started avoiding consuming fatty foods and so in our country there is increase in market for skin less chicken meat which results in generated more chicken skin as a by-product. Hence, this study was conducted with the objectives of extraction and characterization of collagen from chicken skin and to develop collagen sheet for biomaterial application.
Swallowing of Casson fluid in oesophagus under the influence of peristaltic waves of varying amplitude

The experimentally verified fact that there is a high pressure zone in the lower part of the oesophagus has established that the earlier models fall short of representing the realistic swallowing process in the oesophagus. Since the high pressure is created by gradually increasing amplitudes of peristaltic waves, swallowing of Casson fluid in oesophagus is mathematically remodeled. It is revealed that in the case of exponentially increasing amplitude, pressure is non-uniformly distributed for different cycles. Pressure increases along the entire length of the oesophagus; and finally toward the end of the oesophageal flow, it increases quite significantly, probably to ensure delivery into the stomach. This is a similar observation for Newtonian as well as non-Newtonian fluids but Casson fluids need more pressure; and hence more efforts are required by the oesophagus to transport the fluid forward. When wave amplitude is small, flow rates are small. In such a case, Casson fluid requires higher flow rates fo.
Discrimination of Bacillus sphaericus strains by filtrate protein profiles

are compared both in vegetative and sporulated stages according to their filtrate protein profiles obtained by Native-PAGE and SDS-PAGE. When the strains are compared in the sporulated stage, filtrate protein profiles obtained by Native-PAGE differentiated the strains according to their phage and serogroups. On the other hand, the typing according to filtrate protein profiles is correlated with serotyping and phage typing. The discrimination of
ETFs, Arbitrage, and Shock Propagation

We study whether exchange traded funds (ETFs)—an asset of increasing importance—can amplify the exposure of the securities in their baskets to liquidity shocks. As a preliminary step, we show that ETFs are catalysts for high turnover investors who are, arguably, an important source of liquidity shocks. Then we show that arbitrage trades propagate the liquidity shocks from ETF prices to the underlying securities. Supporting the claim that ETFs add a layer of shocks to their basket securities, the presence of ETFs is associated with an increase in the volatility of the stocks they hold. Finally, as a case study in shock propagation through ETF arbitrage, we provide results suggesting that ETFs facilitated shock transmission between the futures market and the equity market during the Flash Crash of May 6, 2010. Overall, our results highlight the role of financial innovation in increasing non-fundamental volatility and in propagating shocks across markets, especially in association with high frequency trading.
Recurrence of Thalassia testudinum seagrass die-off in Florida Bay, USA: initial observations

Widespread mortality of Thalassia testudinum was first documented in Florida Bay, USA, during the summer of 1987. This unprecedented event spanned 3 yr, affected 40 km2 of seagrass and resulted in more than a decade of ecological disturbances. Initial putative causes for seagrass die-off ranged from climatic anomalies and watershed changes to wasting disease and eutrophication. Subsequent experimental research suggested that hypoxic plant tissue, caused by low water column oxygen content or reduced photosynthesis, allowed intrusion of sulfide leading to plant death. Contributing factors included high temperatures, salinities and T. testudinum biomass, together causing lower oxygen water solubility, higher community respiration rates and elevated nighttime oxygen demand. The Fisheries Habitat Assessment Program (FHAP) has tracked the system’s slow recovery since 1995. Recent FHAP data (2012) indicated that T. testudinum had returned to pre-die-off densities in even the most severely affected locations. During the summer of 2015, following several months of drought, National Park Service researchers reported hypersaline conditions and a recurrence of seagrass die-off in north-central Florida Bay. An interagency effort is presently underway to document the duration, extent, impacts and possible factors responsible for the current mortality. Initial field surveys indicate that there is high spatial coincidence between the current and the 1987−1990 events and that hypersalinity, water column stratification and bottom-water anoxia might have once again resulted in mass mortality of T. testudinum in Florida Bay. The goal of this report is to alert the scientific community to the recurrence of this important ecological event.
Removal of nitrate ions from aqueous solution using chitin as natural adsorbent

ions concentration, temperature and pH were studied. The experimental data were analyzed using Freundlich, Langmuir and Temkin isotherm models to determine the mechanistic parameters related to the adsorption process. It was found out that Langmuir and Freundlich models fitted well. The results also show that the amount of NO3 - ions adsorbed by chitin increased rapidly to reach the equilibrium threshold in a few minutes. The results generally shows that chitin adsorbent can be successfully used to remove NO3 - ions from aqueous
System Safety Property-Oriented Test Sequences Generating Method Based on Model Checking

This paper on a system safety property-oriented test sequence is from the proceedings of the 12th International Conference on Computer System Design and Operation in Railways and Other Transit Systems, held in Beijing, China, in 2010. The authors report on a study in which model checking is used to generate a suite of test sequences to validate whether the System Under Test (SUT) satisfies the defined safety properties. A Colored Petri Net (CPN) model is first abstracted and derived from the system requirement specification of the SUT with a hierarchical modeling approach. A state space analysis is used to verify the model with respect to a set of correctness criteria, including the absence of deadlocks and livelocks. Next, some system safety properties defined by the experts are described with a non-standard query and extended computation tree logic. Finally, the negation of safety properties can be checked by analyzing the occurrence graph and the strongly connected components graph of the model. If the model does not satisfy the specified property, the process of model checking returns some counterexamples. From these counterexamples, the nodes and directed arcs that include the interface information are picked out as the interface messages, which are used to construct a test sequence. The authors present a case study of using this method on a railway control system, where the CPN Tools is used to model and generate test sequences. All reachable states are analyzed to detect violations and generate the safety related test sequences, which include the required data to be executed on the SUT. The authors conclude that this method is time-saving, labor-saving and can guarantee agreement between the SUT and the safety properties.
Media Façades in the Wild: Some Lessons

— Media displays in public areas are becoming increasingly pervasive—they are used in many settings, come in different sizes, serve different purposes, and have varied degrees of interactivity. In this paper, we aim to provide a survey of how these displays, often named media façades, are used in the wild in a city in China which is undergoing a rapid growth. This survey is intended to raise greater awareness and discussion about the use and effect of these displays in public areas. Through this survey, we have been able to distill some lessons of what is good, bad, and ugly about some current examples of media displays used in a city that is transitioning into becoming a modern one and one that is located in one of the fastest growing areas in Asia. With this research, we hope that we can provide technology designers and architects with some general principles that can help them integrate these types of technologies into their architectural creations.
