Title: Investigation and Characterization of MapReduce Applications for Big Data Analytics Authors: Li, Y; Lam, T B V; Do, T V Van; Chakka, R; Rotter, C Abstract: Recently, many organisations have applied Hadoop MapReduce framework for big data analytics. MapReduce applications based on the MapReduce programming model can be developed to process data of large amount. Therefore, understanding a dependency among the resource usage parameters of MapReduce applications is crucially needed from the viewpoint of cloud operators. In this paper, we analyze the inter-dependency of resource usage parameters of MapReduce applications. Autocorrelation of each resource usage parameter and correlation characteristics of each pair of resource usage parameters are investigated. Based on the analysis, we identify several groups of features that can be used to classify MapReduce applications. Page(s): 493-498

Title: Growth Performance of Cultured African Catfish (C.Gariepinus) Fingerlings in the Presence of Nano and MacroCuO Feed Supplements Authors: Onuegbu, U C; Agarwal, A; Singh, N B Abstract: Nanomaterials are having transformational effects on the world of science including animal feeds. The present study investigated the dietary effects of copper oxide nanoparticles on the growth and general health profiles of African catfish (Clarias gariepinus) fingerlings. Conventional catfish feed (initial copper content 0.83 mg Kg^-1) was supplemented with nano (n) and macro forms of CuO at levels of 0, 1, 3, 5, 7 and 10 mg Kg^-1feed respectively. Fish were fed the diets for 7 weeks., after which significant (p < 0.05) weight differences were observed in fish fed 3-10 mg nCuO Kg^-1 feed and those fed 5-10 mg CuO Kg^-1 feed respectively. Highest percent weight gains attained were 620.20% and 491.63% at the supplementation level of 10 mg (nCuO & CuO) Kg^-1 feed respectively, against 322.55±3.19% for the control, suggesting that nCuO was more effective in impacting the health of C. gariepinus than CuO.

Title: FPGA Implementation of Carrier Disposition PWM for Closed Loop Seven Level Diode Clamped Multilevel Inverter in Speed Control of Induction Motor Authors: Kuppuswamy, C L; Raghavendiran, T A Abstract: This work proposes FPGA implementation of Carrier Disposition PWM for closed loop seven level diode clamped multilevel inverter in speed control of induction motor. VLSI architecture for carrier Disposition have been introduced through which PWM signals are fed to the neutral point seven level diode clamped multilevel using which the speed of the induction motor is controlled. This proposed VLSI architecture makes the power circuit to work better with reduced stresses across the switches and a very low voltage and current total harmonic distortion (THD). The output voltages, currents, torque & speed characteristics for seven level neutral point diode clamped multilevel inverter for AC drive was studied. It has observed the proposed scheme introduces less distortion and harmonics. The results were validated using real time THD meters. Page(s): 504-509

Targeting Pro-inflammatory Cytokines and Chemokine as Potential Novel Strategy in Adjuvant Development for Anti- HCV Therapy

Title: Targeting Pro-inflammatory Cytokines and Chemokine as Potential Novel Strategy in Adjuvant Development for Anti- HCV Therapy Authors: El-Deeb, N; El-Adawi, H; Sharaf, M; Enshasy, H A El Abstract: Hepatitis C virus (HCV) is the main cause of chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC) worldwide. The risk for the development of HCC increases with the severity of liver inflammation and fibrosis. Inflammatory cytokines are critical components of the immune system and influence cellular signaling. In this study, we demonstrated that TNF-α, IL-2 & IL-8 levels were significantly elevated in PBMC– HCV in-vitro model. We tested the hypothesis whether Epicatechin (EC) and/or 6-gingerol (GING) could inhibit such elevation in those cytokines or not. We found that both compound could significantly inhibit the inflammatory cytokines and the use of combined treatment is more effective than single treatment (EC or GING), assuming a possible synergistic effect. In conclusion, the use of anti-inflammatory compounds such as EC and GING as combined treatment may offer a pharmacological approach of targeting TNF-α, Il-2 and IL-8 production, which may provide a potential novel strategy for the development of anti-HCV therapy.
