Research ArticleOpen accessIn the abstractCellulolytic Enzymes Production by Solid State Culture Using Pecan Nut Shell as Substrate and SupportMiguel A. Medina-Morales, José L. Martínez-Hernández, Heliodoro de la Garza, Cristóbal Noé AguilarProblem Statement: Great interest in the use of lignocellulosic biomass is increasing in order to diminish the accumulation of residues, such as pecan nut shells. One of the alternatives is the fungal degradation of these residues. Approach: The capacity of Trichoderma (coded as T1, T2 and T3) strains to produce cellulase and xylonite was evaluated. Results: Pecan nut shell fibers … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Edible Coatings, Storage Time and Maturity Stage on Overall Quality of Tomato FruitsJorge Esteban de Jesús Dávila-Aviña, José Villa-Rodríguez, Reynaldo Cruz-Valenzuela et al.Problem statement: Tomato (Lycopersicon esculentum Mill.) is one of the most widely consumed fresh vegetables in the world; however, its highly perishable nature limits its postharvest life. Major losses in tomato quality and quantity occur between harvest and consumption. Therefore, the application of new technologies to extend the postharvest life of this commodity is needed. The use of edible coatings … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 14 Mar 2011 · 11,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractThai Speech Coding Based On Conjugate-Structure Algebraic Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In mobile communication, speech coding aims at compressing the speech with lowest bitrate and highest quality for standard languages such as English, German and French. As for other languages with different uttering styles, the encoded speech quality is not guaranteed at the same bitrate. The appropriate evaluation should be performed to develop the speech quality by applying some … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Activity of Cephalexin against Community-Acquired Urinary Escherichia coli, Klebsiella and Proteus species IsolatesHumodi A. Saeed, Amira Saad Eldin MohammedProblem statement: Resistance among urinary tract pathogens to conventional antibiotics has been considered a health problem worldwide. The aim of this study was to evaluate the in vitro activity of cephalexin on urinary enterobacterial isolates. Approach: Patients with community-acquired urinary tract infections were microbiologically investigated. Urine specimens were collected from each patient. The specimens were cultured on bacteriological media. The … …American Journal of Infectious Diseases, Vol. 6, Issue 4 · 31 Dec 2010 · 8,182 accessesView PDFCite
