Research ArticleOpen accessIn the abstractComparative Study of Volatile Compounds from Genus OcimumS. Raseetha Vani, S. F. Cheng, C. H. ChuahThere are distinct varieties of basil types in the genus Ocimum which makes them very special. Genus Ocimum is widespread over Asia, Africa and Central & Southern America. All basils are member of the Lamiaceae family. The colors of the leaves vary from bright green to purple-green and sometimes almost black. Fresh basil leaves have a strong and characteristic aroma, … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 12,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiatrizoate, Iopromide and Iotrolan Enhanced Cytotoxicity of Daunorubicin in Multidrug Resistant K562/adr Cells: Impaired the Mitochondrial and Inhibited the P-Glycoprotein FunctionNitaya Snitwongse Na Ayudhya, Samlee MankhetkornMultidrug resistance was an obstacle in cancer chemotherapy because the cells decreased their intracellular drug accumulation by energy-dependent compounds efflux pumps such as P-glycoprotein (P-gp). This study observed some iodinated radiographic contrast media, diatrizoate, iopromide and iotrolan affected the cellular energetic state and the kinetics of P-gp in drug-sensitive K562 and drug resistant K562/adr cell lines using spectrophotometer and spectrofluorometer. … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization and Wash Performance Analysis of Microbial Extracellular Enzymes from East Calcutta Wetland in IndiaRamesh Malathu, Sanhita Chowdhury, Madhusmita Mishra et al.Extracellular protease from a novel bacterial isolate showing maximum similarity of 98.22% with Microbacterium luteolum was obtained from East Calcutta Wetland, India. It showed compatibility with commercial detergents. The enzyme retains more than 60% of its activity between 6.0 to 10.5 pH. The maximum activity is at pH 7.5 with 71% activity at pH 10.0 and 10.5. The protease retained … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 8,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtility of Certain Π Acceptors for Spectrophotometric Determination of Sildenafil CitrateNora H. Al-ShaalanSildenafil citrate was determined through charge transfer complexes (CTC) formation with three electron acceptor reagents. The methods involve the reaction of Sildenafil citrate as n-donor with either Chloranil (tetrachloro 1,4-benzoquinone), tetracyanoethylene (TCNE) or 7,7,8,8-tetracyanoquinodimethane (TCNQ) as n-acceptors, to give a stable and highly colored radical anion. The colored products were quantified spectrophotometrically. The condition ranges adhering to Beer's law are … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,164 accessesView PDFCite
Research ArticleOpen accessIn the abstractValidation of Some Bridge Pier Scour Formulae Using Field and Laboratory DataThamer A. Mohamed, Megat J.M.M. Noor, Abdul H. Ghazali, Bujang B.K. HuatEstimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data. Validation of these formulae is necessary in order to ascertain which of the formulae will give a reasonable estimate of the local … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,826 accessesView PDFCite
