Research ArticleOpen accessIn the abstractThe Characterization of Bacillus thuringiensis from soil habitat of Auky Island, Padaido District in Biak Numfor Regency and Its Toxicity against Mosquito Larva of Anopheles spLantang Daniel, Rampa Ester, Lunga NellyBacillus thuringiensis (Bt) is bacteria that produce protein crystals as an insecticidal against various vector diseases in plants and animals including humans. The purpose of this research is to discover the local isolate toxicity of B. thuringiensis from Auky Island Padaido District in Biak Numfor Regency against mosquito larva Anopheles sp., as well as to discover the local isolate of … …American Journal of Infectious Diseases, Vol. 14, Issue 2 · 4 Sep 2018 · 9,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEURAL CASCADED WITH FUZZY SCHEME FOR CONTROL OF A HYDROELECTRIC POWER PLANTA. Selwin Mich Priyadharson, T. Ramesh Kumar, M. S. Saravanan et al.A novel design for flow and level control in a hydroelectric power plant using Programmable Logic Controller (PLC)-Human Machine Interface (HMI) and neural cascaded with fuzzy scheme is proposed. This project will focus on design and development of flow and level controller for small scale hydro generating units by implementing gate control based on PLC-HMI with the proposed scheme. The … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMBINATION OF CONVENTIONAL AND IN-SILICO APPROACH FOR IDENTIFYING AN INDUSTRIALLY IMPORTANT ISOLATE OF AEROMONASThungri Ghoshal, Sourav Ghosh, Amrita Saha et al.Ammonia is required for various commercial applications while its production by standard process is immensely energy intense. Dairy industry on the other hand produces huge volume of effluent needing treatment before discharge. This study aims at developing an eco-friendly microbial approach for conversion of dairy industry effluent into ammonia under atmospheric pressure and 37°C temperature at laboratory scale. Thus the … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 26 Feb 2014 · 7,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Supercritical Fluid Extraction and BioprocessingOwen Catchpole, Stephen Tallon, Peter Dyer et al.Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO2 is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,488 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariability of Hydraulic Conductivity Due to Multiple FactorsSanjit K. Deb, Manoj K. ShuklaSoil properties are greatly influenced by intrinsic factors of soil formation as well as extrinsic factors associated with land use and management and vary both in time and space. Intrinsic variability is caused by the pedogenesis and usually takes place at large time scales. The variability caused by extrinsic factors could take effect relatively quickly and could not be treated … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 13 Aug 2012 · 10,219 accessesView PDFCite
