Abstract

Fibre was extracted from stem of Dhaincha (Sesbania aculelata) by 15 days tank retting. It is harsh, coarse and shiny fibre but lacks the elasticity, which was further processed for scouring with 1 per cent KOH and bleached with 1 per cent H₂O₂. Treated fibres which were obtained after treatment with 1 per cent KOH and 1 per cent H₂O₂ had good in strength, fineness, moisture regain, elongation and whiteness index.

Abstract

A Lipoxygenase inhibitor is a drug which slows down or stops the action of the lipoxygenase enzyme. More precisely, the term is almost always used to describe an inhibitor of the arachidonate 5-lipoxygenase enzyme, which transforms EFAs into leukotrienes. Examples include-Azelastine diethylcarbamazine, nordihydroguaiaretic acid, zileuton, In this study we have investigated that the oxidation of various substrates (linoleic acid, methyl linoleate, phosphatidylcholine, isolated LDL, and human plasma) by the arachidonate 15-lipoxygenases from rabbit reticulocytes and soybeans aiming at elucidating the effects of substrate, lipoxygenase and reaction milieu on the contribution and mechanism of random oxidation and also the effect of antioxidant.The complete descriptors data set of all compounds were considered as independent variable and biological activity as dependent variable www. ncss. com software was used to generate QSAR models by step wise multiple linear regression analysis statistical measures used were n-number of compounds in regression, in correlation coefficients F-test (Fischer's value for statistical significance). SE-standard error of estimations and correlation matrix to show correlation. This is clearly predict that our proposed tetra parametric model in most appropriate model for modeling inhibition activity log1/IC₅₀, for lipoxygenase inhibitor set of 41 compounds. Finally I obtained my results, that is suggesting that proposed combination QSAR models could be useful in predicting the Lypoxygenase inhibiting activity of Arachidonate 5-Lypoxygenase enzyme.

Abstract

Mobile ad hoc networks (MANETs) are a setup of several independent nodes that are capable of transmitting any kind of data by themselves. In MANETs, the node themselves act as routers and the setup can either be single hop or multihop depending on the application. These devices have wide and varied applications; like in military deployment, for network set up in meetings, electronic classrooms etc. As the applications and use of MANETs has increased, it has also become imminent for MANETs to support multimedia transmission, high quality data transmission and also to work efficiently in a congestion scenario. To support these parameters it is necessary to have a robust routing protocol that provides good Quality of Service (QoS) parameters under different conditions. In this paper the authors simulate transmission of multimedia traffic with AODV nthBR routing protocol for a high density MANET setup. AODV nthBR routing protocol is also simulated for a congestion scenario and the results are then compared with the existing routing protocols.

Abstract

Objectives: In this paper, a backup routing solution in which routes are selected based on their energy efficiency is presented. Methods: The selection of nodes is based on energy efficiency. Nodes that are nearest to the failed node are found out and checked for their energy efficiency. Depending on whether nodes are energy efficient or not, they are classified as alive or dead. The selected node is then used for data transmission to the destination. Backup routing is done with the help of alive or energy efficient nodes. These nodes are first chosen based on how close they are from the failed node and then the energy available with them is checked. It is shown through experimental results that the obtained QoS parameters are better than the traditional routing protocols. Findings: It is found that after 6000 rounds of transmission, in a MANET of size 100 nodes, throughput obtained with energy efficient AODV BR protocol is 107800 bits. Also, PDF obtained is 0.187 and end to end delay is 0.05422 secs after 6000 rounds. Applications: MANETs find use in education purpose like e-classrooms, in war zones, in disaster affected areas or even in places where the cost of establishing a setup needs to be minimized. MANETs have diverse applications such as in warfare, earthquake or disaster stricken areas etc. and require good Quality of Service (QoS) parameters. The existing work provides QoS parameters when the link is not broken. However it is desirable to provide a system that continues to provide good QoS parameters even when the existing link fails. In this paper efforts have been made to provide for such a system that searches for an alternate link on failure of the main route based on certain energy efficiency criteria such that the network provides good QoS parameters in various applications.

Abstract

College can be a time of intellectual discovery and personal growth For students of the traditional age-those in transition from adolescence to adulthood-college offers a chance to question assumptions held over from childhood and thus to mould a new adult identity. Sometimes this questioning may lead to an identity crusty and to serious problems: abuse of alcohol or drugs, eating disorders risk taking, and even suicide. Fortunately, however, it is more often fosters healthy development.

Abstract

Pneumocystis is a genus of unicellular fungi found in the respiratory tracts of many mammals and humans. Distinct genomic variability exists between host-specific members of the genus. The patient population comprised 83 females (81.7%) and 19 males (18.3%). The mean age of the patients when they received their first biologic agent was 58.0 years (range, 14 to 86 years).The mean observation period was 16.6 months (range,2 weeks to 60 months) and 21 patients (20.1%) received TMP/SMX prophylaxis. A total of 38 patients (37.7%) had coexisting pulmonary disease, 44 patients (43.2%) received glucocorticoid therapy and the mean dose (±SD) of glucocorticoid (converted to the prednisolone (PSL) equivalent) was 4.46 mg ± 3.64 mg. A total of 78.5% of patients were given MTX, and the average dose of MTX in patients treated with MTX was 8.96 mg/wk. Nine (1.28%) of the one hundred two patients developed PCP, and none of the patients in the group treated with TMP/SMX prophylaxis developed PCP. There are 81patients, the mean age in their group was significantly older (68.9 years vs. 55.3 years); the serum level of IgG was significantly lower (1,496 mg/dl vs. 1,619 mg/dl); the dose of MTX was significantly lower (6.09 mg vs.7.28 mg); and the ratios of patients treated with glucocorticoids, PCP complicated with coexisting pulmonary disease and PCP complicated with DM were significantly higher (53.9% vs. 40.8%, 72.3% vs. 29.1% and 21.3% vs.10.5%, respectively).

Abstract

In this paper, the Mobile Ad Hoc Networks (MANETs) with integrated Primary/Secondary User (PU or SU) traffic has been considered. Nodes in the MANET are equipped with Cognitive Radio Technology (CRT). The blocking probability and dropping probability for SUs are obtained by considering a 3D Markov Chain analytical model. To provide efficient service to PUs, we offer priority of channels, higher priority and lower priority is given to PUs and SUs, respectively. The expressions for blocking probability, dropping probability, throughput and non-completion of SU are established. Sensitivity analysis is carried out to explore the effect of system parameters. It is observed that Ad Hoc network utilized the unused spectrum of the existing legacy systems in an opportunistic manner in addition to using the unlicensed spectrum. The results show an improved performance in terms of blocking probabilities, dropping probabilities of SU and over all throughput of the system.
