Abstract: The effect of the alcoholic extract of Saccharum spontaneum (Poaceae) against glycolic acid induced urolithiasis urolithiasis in albino rats is summarized in this study. Lithiasis was induced in rats by fed with a calculi-producing diet (CPD: commercial diet mixed with 3% glycolic acid) for 28 days and was manifested by high urinary calcium, phosphate, oxalate, protein, and low urinary magnesium content. Therapeutic treatment with plant extract (200 and 300mg/kg b.wt.dose-1 day-1oral-1) has significantly ameliorated to near normalcy in the curative group. It also increased the urine volume, thereby reducing the tendency for crystallization. These results of the present study concluded that S.spontaneum can play an important role in the prevention of disorders associated with kidney stone formation.

International Journal of Pharmaceutical and Phytopharmacological Research , 2012,
Abstract: The present investigation was intended to evaluate the toxicity of the ethanolic root extract of a traditionally used plant Saccharum spontaneum Linn (S.spontaneum). The acute toxicity studies was done on male wistar albino rats which showed no clinical signs, no mortality of the rats even under higher dosages levels (50, 150, 300, 500, 1000, 2000mg/kg b.wt) indicating the high margin of safety of the plant extract. The sub acute toxicity study was done to find out the effective dosage of the plant in rats. The varying doses (100,200,300,400, and 500mg/kg b.wt) of the plant extract were administered orally to different groups of male wistar strain of albino rats on daily basis and sacrificed after 28 days of administration. There was no change in the body weight and no mortality was found in the experimental animals during the study period. The record of biochemical parameters like calcium, oxalate, phosphorus, magnesium protein, urea, uric acid, creatinine, sodium, potassium and chloride in treatment groups of rats were non significant in comparison with control group of rats. The parameters remained within the normal range. The results of study have suggested there was no obvious toxicity observed with the treatment of S.spontaneum It was found to be safe alternative for various severe infections.

Abstract: The ethanolic extract of roots of Saccharum spontaneum Linn. was evaluated for its antilithiatic activity in rats. Lithiasis was induced by oral administration of ethylene glycolated water (0.75%) in adult male wistar albino rats for 28 days. The ionic chemistry of urine was altered by ethylene glycol (EG), which elevated the urinary concentration of crucial ions, viz. calcium, phosphorus and protein thereby contributing to renal stone formation. However treatment with ethanolic root extract of S.spontaneum (200 and 300 mg / kg bodyweight) in group III and IV significantly (p<0.05) reduced the elevated level of these ions in urine. The levels of serum urea, uric acid and creatinine were significantly increased (p < 0.05) in urolithiatic rats. Treatment with plant extract restored the levels and it brought back the values to near normal range in urolithiatic rats. All these observations revealed that ethanolic root extract of S.spontaneum has curative effect on stone formation induced by ethylene glycol.

Abstract: Aim: The present study involves in the investigation of various extracts of Cucumis trigonus Roxb. for its phytochemical constituents and also the cytotoxic potential of the Cucumis trigonus Roxb. ethanolic fruit extract. Methods: The phytochemical screening with methanol, ethanol, petroleum ether, chloroform and aqueous extracts of Cucumis trigonus Roxb. was done by modern method of Peach and Tracey (1955) Cytotoxicity is estimated by staining technique using Trypan blue after the addition of drug, the dead cells are stained blue with Trypan blue. Confirmation studies were done by additional metabolic intervention experiments like (3-(4, 5-dimethyl thiazol-2yl)-2, 5-diphenyl tetrazolium bromide) MTT assays. Results: Qualitative phytochemical analysis of the plant extracts were done and it was found that the presence of phytochemicals were maximum in the ethanolic extract when compared to other extracts. So the ethanolic extract of C. trigonus fruit was used for further investigations. In the cytotoxic study the ethanolic fruit extract concentration at 1.25 mg / ml was found to be the effective dose because at this concentration, it exhibited 50% cytotoxicity against Hep2 cells. Conclusion: These results conclude that the ethanolic fruit extract of Cucumis trigonus possess a good phytochemical strength and also an effective cytotoxic potential.

Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.78170
Abstract: In recent years, renewable energy resources are utilized to meet the growing energy demand. The integration of renewable energy resources with the grid incorporates power electronic converters for conversion of energy. These power electronic converters introduce power quality issues such as a harmonics, voltage regulation etc. Hence, to improve the power quality issues, this work proposes a new control strategy for a grid interconnected solar system. In this proposed work, a maximum power point tracking (MPPT) scheme has been used to obtain maximum power from the solar system and DC/DC converter is implemented to maintain a constant DC voltage. An active filtering method is utilized to improve the power quality of the grid connected solar system. The proposed system is validated through dynamic simulation using MATLAB/Simulink Power system toolbox and results are delivered to validate the effectiveness of the work.

Memory Constrained ANT Colony System for Task Scheduling in GRID Computing
T.Kokilavani,D.I. George Amalarethinam
International Journal of Grid Computing & Applications , 2012,
Abstract: Grid computing solves the increasing need of scientific, engineering and research problems. It combinesthe geographically distributed resources to solve a computation intensive problem which cannot be solvedusing a single resource. Resource sharing requires more optimized algorithmic structure, otherwise theresponse time is increased and the resource utilization is reduced. In order to avoid such reduction in theperformance of the grid system, an optimal resource sharing algorithm is required. The ACO solves manyengineering problems and provides optimal result which includes Travelling Salesman Problem, NetworkRouting, and Scheduling. This paper proposes Load Shared Ant Colony Optimization (LSACO) whichshares the load among the available resources. The proposed method considers memory requirement as aparameter to distribute the load among Grid resources. LSACO reduces the overall response time andincreases the resource utilization and number of tasks scheduled. The proposed method has been tested fordifferent types of tasks and resources.

Journal of Artificial Intelligence , 2012,
Abstract: Digital audio has become very popular in the last two decades with the growth of multimedia systems and the World Wide Web. So, audio processing techniques such as filtering, equalization, noise suppression, compression, addition of sound effects and synthesis become necessary in the field of sound engineering. This study has presented some of the audio enhancement techniques using adaptive Least Mean Square (LMS) filters with the Field Programmable Gate Array (FPGA) Architectures which are developed using Xilinx System Generator (XSG). Verilog descriptions from XSG are synthesized to the target FPGA device-a Virtex4 xc4vsx55-12ff1148 and the resource utilization summary for the various alternate LMS architectures is obtained along with the Signal-to-Noise Ratio (SNR) calculations. Results show that Delayed LMS architectures provide a better SNR improvement at the cost of more resource utilizations.

R. Prema, R. Rangarajan
Wireless Sensor Network (WSN) , 2012, DOI: 10.4236/wsn.2012.45019
Abstract: Several wireless sensor network applications ought to decide the intrinsic variance between energy efficient communication and the requirement to attain preferred quality of service (QoS) such as packet delivery ratio, delay and to reduce the power consumption of wireless sensor nodes. In order to address this challenge, we propose the Power Aware Routing Protocol (PARP), which attains application-specified communication delays at low energy cost by dynamically adapting transmission power and routing decisions. Extensive simulation results prove that the proposed PARP attains better QoS and reduced power consumption.
