Abstract: In the present work, we make confrontation of our theoretical calculations using quantum molecular dynamics model with the experimental data for the reactions of $^{40}Ar$ +$^{45}$Sc, $^{197}Au$ +$^{197}$Au and $^{129}Xe$ +$^{119}$Sn at different incident energies. In these reactions, we display the charge distribution and energy dependence of fragments multiplicity. Our results indicate good agreement with the experimental data for all the reactions.
Multifunction Filter Employing Current Differencing Buffered Amplifier  [PDF]
Tajinder Singh Arora, Udit Rana
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.75046
Abstract: This paper proposes a new filter biquad circuit, which utilizes three Current Differencing Buffered Amplifiers (CDBA), two capacitors and five resistors, and operates in the trans-resistance mode. This multi-input and single-output multifunction filter uses only grounded capacitors. All the employed resistors are either grounded or virtually grounded, which is an important parameter for its implementation as an integrated circuit. The circuit enjoys independent tunability of angular frequency and bandwidth. The 0.5 μm technology process parameters have been utilized to test and verify the performance characteristics of the circuit using PSPICE. The non-ideal analysis and sensitivity analysis, transient response, Monte-Carlo analysis and calculations of total harmonic distortion have also been shown.

Abstract: ngiotensin (1-7)/Mas receptor axis activation ameliorates the changes in fatty acid composition in diabetic rats with nephropathy Original Research (3014) Total Article Views Authors: Kulwinder Singh, Tajinder Singh, PL Sharma Published Date November 2010 Volume 2010:2 Pages 163 - 168 DOI: http://dx.doi.org/10.2147/JEP.S14342 Kulwinder Singh*, Tajinder Singh*, PL Sharma Department of Pharmacology, ISF College of Pharmacy, Moga India; *These authors contributed equally to this work Abstract: Diabetes mellitus is often associated with altered fatty acids composition. This study was designed to investigate the role of angiotensin (Ang) (1-7)/Mas receptor in improving fatty acids composition in streptozotocin (STZ)-induced diabetic nephropathy (DN) in rats. Rats treated with STZ (50 mg/kg, i.p. once) developed DN after 8 weeks. Fatty acid composition was estimated in renal cortical tissue by gas chromatography. Treatment with Ang (1-7), A-779, and Ang (1-7) plus A-779 was given from week 4 to week 8. Diabetic rats exhibited a significant increase in levels of saturated fatty acids and a significant decrease in levels of polyunsaturated fatty acids (PUFAs). Treatment with Ang (1-7) significantly attenuated these diabetes-induced changes. In diabetic rats, prior administration of A-779 significantly attenuated the increase in PUFAs produced by Ang (1-7); however, for saturated fatty acids, A-779 significantly blocked the decrease in palmitic acid only. Our study, for the first time, documented that endogenous Ang (1-7) modulates fatty acid composition in rats. Further, treatment with Ang (1-7) significantly attenuated diabetes-induced changes in fatty acids composition. This may be an additional mechanism implying the renoprotective role of Ang (1-7) in diabetic rats.

International Journal of Green Pharmacy , 2010,
Abstract: Anisomeles malabarica (AM) R.Br. (Lamiaceae) is an aromatic perennial herb, the leaves of which are traditionally used to treat convulsions in southern India. The present study has been designed to investigate the anticonvulsant potential of chloroform, ethyl acetate and methanol extracts of leaves of AM against pentylenetetrazole (PTZ) and maximal electroshock (MES) induced convulsions. All the three extracts were administered (i.e. 100, 200, 400 mg/kg, p.o.) for 7 days and at the end of the treatment convulsions were induced experimentally. Diazepam and phenytoin (1 mg/kg, i.p. and 25 mg/kg, i.p., respectively) were used as reference anticonvulsant drugs against experimentally induced convulsions. High doses (400 mg/kg, p.o.) of chloroform and ethyl acetate extracts both significantly decreased the extent of MES- and PTZ-induced convulsions. On the other hand, ethyl acetate extract at lowest and medium selected doses (i.e. 100 mg/kg, p.o. and 200 mg/kg, p.o., respectively, for 7 days) had also significantly attenuated PTZ-induced convulsions. However, methanol extract at any of the doses used (i.e. 100, 200 and 400 mg/kg, p.o.) did not show any significant effect on PTZ- and MES-induced convulsions. None of the extracts at doses used in the present study have altered locomotor activity and motor coordination. Hence, it may be concluded that chloroform and ethyl acetate extracts of AM leaves are effective against PTZ- and MES induced-convulsions in rats.

Abstract: Privacy Security of data in Cloud Storage is one of the main issues. Many Frameworks and Technologies are used to preserve data security in cloud storage. [1] Proposes a framework which includes the design of data organization structure, the generation and management of keys, the treatment of change of user's access right and dynamic operations of data, and the interaction between participants. It also design an interactive protocol and an extirpation-based key derivation algorithm, which are combined with lazy revocation, it uses multi-tree structure and symmetric encryption to form a privacy-preserving, efficient framework for cloud storage. [2] Proposes a framework which design a privacy-preserving cloud storage framework in which he designed an interaction protocol among participants, use key derivation algorithm to generate and manage keys, use both symmetric and asymmetric encryption to hide the sensitive data of users, and apply Bloom filter for cipher text retrieval. A system based on this framework is realized. This paper analyzes both the frameworks in terms of the feasibility of the frameworks, running overhead of the system and the privacy security of the frameworks.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0096939
Abstract: Utilization of “hidden genes” from wild species has emerged as a novel option for enrichment of genetic diversity for productivity traits. In rice we have generated more than 2000 lines having introgression from ‘A’ genome-donor wild species of rice in the genetic background of popular varieties PR114 and Pusa44 were developed. Out of these, based on agronomic acceptability, 318 lines were used for developing rice hybrids to assess the effect of introgressions in heterozygous state. These introgression lines and their recurrent parents, possessing fertility restoration ability for wild abortive (WA) cytoplasm, were crossed with cytoplasmic male sterile (CMS) line PMS17A to develop hybrids. Hybrids developed from recurrent parents were used as checks to compare the performance of 318 hybrids developed by hybridizing alien introgression lines with PMS17A. Seventeen hybrids expressed a significant increase in yield and its component traits over check hybrids. These 17 hybrids were re-evaluated in large-size replicated plots. Of these, four hybrids, viz., ILH299, ILH326, ILH867 and ILH901, having introgressions from O. rufipogon and two hybrids (ILH921 and ILH951) having introgressions from O. nivara showed significant heterosis over parental introgression line, recurrent parents and check hybrids for grain yield-related traits. Alien introgressions were detected in the lines taken as male parents for developing six superior hybrids, using a set of 100 polymorphic simple sequence repeat (SSR) markers. Percent introgression showed a range of 2.24 from in O. nivara to 7.66 from O. rufipogon. The introgressed regions and their putative association with yield components in hybrids is reported and discussed.

Abstract: TBI was induced by controlled cortical impact (CCI) in adult male rats. GSNO or 3-Morpholino-sydnonimine (SIN-1) (50 μg/kg body weight) was administered orally two hours following CCI. The same dose was repeated daily until endpoints. GSNO-treated (GSNO group) or SIN-1-treated (SIN-1 group) injured animals were compared with vehicle-treated injured animals (TBI group) and vehicle-treated sham-operated animals (Sham group) in terms of peroxynitrite, NO, glutathione (GSH), lipid peroxidation, blood brain barrier (BBB) leakage, edema, inflammation, tissue structure, axon/myelin integrity, and neurotrophic factors.SIN-1 treatment of TBI increased whereas GSNO treatment decreased peroxynitrite, lipid peroxides/aldehydes, BBB leakage, inflammation and edema in a short-term treatment (4-48 hours). GSNO also reduced brain infarctions and enhanced the levels of NO and GSH. In a long-term treatment (14 days), GSNO protected axonal integrity, maintained myelin levels, promoted synaptic plasticity, and enhanced the expression of neurotrophic factors.Our findings indicate the participation of peroxynitrite in the pathobiology of TBI. GSNO treatment of TBI not only reduces peroxynitrite but also protects the integrity of the neurovascular unit, indicating that GSNO blunts the deleterious effects of peroxynitrite. A long-term treatment of TBI with the same low dose of GSNO promotes synaptic plasticity and enhances the expression of neurotrophic factors. These results support that GSNO reduces the levels of oxidative metabolites, protects the neurovascular unit, and promotes neurorepair mechanisms in TBI.Neurobehavioral dysfunctions associated with traumatic brain injury (TBI) are the consequences of oxidative injury in the neurovascular unit that results in a damaging progression. These pathological events include continuous production of reactive oxidizing species and inflammation leading to disruption of the blood brain barrier (BBB), altered tissue homeostasis, axon/myelin loss
Simulation and Analysis of AODV routing protocol in VANETs
Tajinder Kaur,A. K. Verma
International Journal of Soft Computing & Engineering , 2012,
Abstract: Vehicular Ad Hoc Network (VANET) is a form of Mobile Ad Hoc Networks (MANET). The field of VANETs started gaining attention in 1980s and has now been an active field of research and development. VANETs provide us with the infrastructure for developing new systems to enhance drivers’ and passengers’ safety and comfort. There are many routing protocols that have been proposed and assessed to improve the efficiency of VANET. Simulator tool has been preferred over outdoor experiment because it is simple, easy and cheap. In this paper, simulation of one of the routing protocols i.e. AODV is done on simulators which allow users to generate real world mobility models for VANET simulations. The tools used for this purpose are SUMO, MOVE and NS2. MOVE tool is built on top of SUMO which is an open source micro-traffic simulator. Output of MOVE is a real world mobility model and can be used by network simulator NS-2. Then graphs were plotted using Tracegraph for evaluation. Based on the simulation results obtained, the performance of AODV is analyzed and compared in three different node density i.e. 4, 10 and 25 nodes with respect to various parameters like Throughput, Packet size, Packet drops, End to End delay etc.
