Research ArticleOpen accessIn the abstractIn Vitro Antagonistic Antifungal-Activity of Streptomyces Isolate 339 Against Magnaporthe oryzaeM. Ebrahimi Zarandi, G. H. Shahidi Bonjar, F. Padasht DehkaeiBiological control offers an environmentally friendly alternative to the use of antimicrobials for controlling plant diseases. A collection of about 100 Actinomycete strains was screened for the ability to produce metabolites that inhibit Magnaporthe oryzae growth in vitro. The Streptomyces isolate 339 showed strong in vitro antagonistic activity against M. oryzae in Agar disc and Well-diffusion methods by producing extracellular … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 8,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Energy-Efficient, Secure and Reliable Wireless Sensor Networks Routing Protocol Based on Data Aggregation and User AuthenticationA. Gopi Saminathan, S. KarthikData aggregation protocols are required in Wireless Sensor Networks (WSNs) to improve the data accuracy and extend the network lifetime by reducing the energy consumption. The existing Data Aggregation-Optimal LEACH (DAO-LEACH) protocol for WSN is enhanced in terms of security and fault-tolerance based on Gracefully Degraded Data Aggregation (GDDA) to ensure the integrity of the aggregated data and Hybrid Layer … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIOCHEMICAL, NUTRIENT AND INHIBITORY CHARACTERISTICS OF STREPTOMYCES CULTURED FROM A HYPERSALINE ESTUARY, THE LAGUNA MADRE (TEXAS)Luis E. Espinoza, Anita L. Davelos Baines, Kristine L. LoweStreptomyces are common soil bacteria that produce secondary metabolites, including several antibiotics; however, the characteristics of marine Streptomyces are largely unknown. Sediment samples were taken from 3 sites in the Laguna Madre to isolate marine Streptomyces. Sediment was diluted, spread onto synthetic seawater media to estimate the total bacterial density of the samples and spread onto starch casein agar to … …OnLine Journal of Biological Sciences, Vol. 13, Issue 1 · 7 Feb 2013 · 7,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractReligion and Schools in a Liquid WorldFrank PetersThis study is an exploration of the changing contexts within which schools are required to function. As global borders have become more porous schools are challenged to deal with students from increasingly diverse cultural, linguistic and religious backgrounds, frequently in a political context that is explicitly secular or nondenominational. This perspective may not be perceived by all to be as … …Journal of Social Sciences, Vol. 8, Issue 3 · 10 Aug 2012 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimizing Interference in Wireless Mesh Networks Based Telemedicine SystemMohammad Siraj, Kamalrulnizam Abu BakarProblem statement: It has been always a challenging task for the researchers to incorporate information technology advancements in the medical profession. In order to guarantee a reliable network infrastructure that supports the employment of wireless technology and mobile devices, a hybrid infrastructure that integrates wireless networks with the traditional wired Local Area Networks (LANs) is needed. The wired network will … …Journal of Computer Science, Vol. 8, Issue 8 · 14 Jul 2012 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Biological Treatment of Low Level Pesticide WastewaterAbdel E. Ghaly, Deepika DavePesticides are chemical substances intended to protect food crops and livestock from pests in order to pro-mote agricultural productivity and protect public health. Contamination of soil, air and water and threat to human and animal health are the major constraints in the use of pesticides. Treatment of pesticide contaminated water is, therefore, paramount. Biological treatment provides the most economical option … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 4 Jul 2012 · 8,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Cluster Based Routing Technique with Multiple Sinks for Wireless Sensor NetworksS. V. Manisekaran, R. VenkatesanProblem Statement: In order to reduce or minimize energy consumption and to improve bandwidth utilization in Wireless Sensor Networks (WSN), it was essential to consider its architecture in the network topology, power consumption, data rate and fault tolerance. Our objective is to formulate an effective cluster formation of nodes with multiple sinks to reduce power consumption and minimize the data … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Resource Allocation Architecture for Mobile GridS. Thenmozhi, A. Tamilarasi, P. T. VanathiProblem statement: In order to achieve high level of reliability and availability, the grid infrastructure should be fault tolerant. Since the failure of resources affects job execution fatally, fault tolerance service is essential to satisfy QoS requirement in grid computing with respect to mobile nodes. Approach: We propose a fault tolerant technique for improving reliability in mobile grid environment considering … …Journal of Computer Science, Vol. 8, Issue 6 · 7 Apr 2012 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cyanobacterium Synechocystis sp. PCC 6803 Glutaredoxin Gene (slr1562) Protects Escherichia coli against Abiotic StressesAhmed Gaber, Salah El-Din El-AssalProblem statement: Glutaredoxins (GRXs) are ubiquitous small heat stable glutathione-dependent oxidoreductase enzymes that play a crucial role in plant development and response to oxidative stress. Approach: Cyanobacterium Synechocystis strain PCC 6803 contains two genes (slr1562 and ssr2061) encoding glutaredoxins. In the present investigation the slr1562 gene (grxC) was isolated and characterized. Results: The results revealed that the amino acid sequence … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrenatal Exposure to Chronic Ethanol on N Methyl D Aspartate Receptor DistributionM. Taherianfard, B. Geramizadeh, E. Evazi, M. SharifiProblem statement: Effect of chronic exposure to ethanol on NR1 subunit of the NMDA receptor distribution in chick embryo brain chronic ethanol intake leads to the development of dependence on and tolerance to ethanol in both human and animals. The glutamate system plays a major role in mediating ethanol effects on brain and behavior.
