Research ArticleOpen accessIn the abstractEvaluating Toxicity of Extracted Destruxin from Metarhizium Anisopliae Against Citrus Leafminer, Phyllocnistis citrellaM. Mohammadi Sharif, A. R. Hadizadeh, M.A. Tajick GhanbaryProblem statement: The fungus, Metarhizium anisopliae (Metschnikoff) Sorokin produces some cyclic peptide toxins, destruxins, which exhibit a variety of insecticidal actions. Citrus leafminer, Phyllocnistis citrella Stainton, is a major pest of young citrus trees; therefore its effective and safe control is a important issue. Approach: Five isolates of M. anisopliae were inoculated in Potato Dextrose Broth (PDB) mediums. Destruxin was … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,251 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinite Element Modeling of Transient Temperatures in a Small-Caliber ProjectileM. Brian Thomas, Leon DozierProblem statement: Future generations of intelligent munitions will use Microelectromechanical Systems (MEMS) for guidance, fuzing logic and assessment of the battlefield environment. The temperatures fund in a gun system, however, are sufficient to damage some materials used in the fabrication of MEMS. The motivation of this study is to model the dynamic temperature distribution in a typical small-caliber projectile. Approach: … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,045 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Proteomics Analysis of Drought Stress-Responsive Proteins as Biomarker for Drought-Tolerant Sugarcane CultivarsNisachon Jangpromma, Supansa Kitthaisong, Khomsorn Lomthaisong et al.Problem statement: The prime objective in breeding selection process of drought-tolerant sugarcane is to identify the correlating marker, which could lead to rapid screening for drought-tolerant cultivars. In this study, we have reported an unknown 18-kDa protein (p18) along with other stress-inducible proteins to be highly expressed in sugarcane leaves under drought stress condition. Approach: The 2D-PAGE patterns of proteins … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 9,814 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFreshwater Situation in Kuwait-Remote Sensing Inputs on Possibility of Artificial RechargeM. Al-Murad, S. Uddin, A. Al-DousariProblem statement: Kuwait is an arid country having per capita freshwater consumption of 485 l day-1. Almost the entire freshwater requirements are met through desalination. The water tariffs in the country are very low consequent to 60% subsidy provided by the government. The use of tertiary treated wastewater is restricted to irrigation and forestation; this leaves huge surplus that can … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,409 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of the Activity of Plant Extracts in Boer GoatsM. Worku, R. Franco, J. H. MillerProblem statement: The effect of extracts from Neem (Azadirachta indica), Wormwood (Artemisia absinthium) and Tobacco (Nicotiana tabacum) with added copper sulfate, on female Boer goats infected with gastrointestinal parasites (GIN) was evaluated. Approach: Following initial screening for infection, animals were artificially infected with a mix containing approximately 80% Haemonchus contortus and 20% Trichostrongylus spp. After 21 days, fecal samples were … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 21 Dec 2009 · 8,471 accessesView PDF Cite
