Research ArticleOpen accessIn the abstractControl of Oxygen Concentration by Using a Carbonaceous SubstanceMohanad Jadan, Jihad Said AddasiThe control of oxygen concentration in gas flow may be used in chemical industry, heat power engineering, ecology, automobile construction and other industrial branches. This control is realized over a broad range of oxygen concentrations. The control of the oxygen concentration is based on passing of gas flow through a measuring cavity of radio spectrometer and measurement of a magnetic … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of (E) 10-Hydroxy-8-octadecenoic Acid with Lyophilized Microbial CellsA. Bódalo, J. Bastida, M.F. Máximo et al.Lyophilized non-proliferating microbial cells of Pseudomonas sp. 42A2 showed their ability to catalyze the bioconversion of oleic acid into (E)-10-hydroxy-8-octadecenoic acid (MHOD) and (E)- 7,10-dihydroxy-8-octadecenoic acid (DHOD). The reaction conditions were optimized in order to produce the maximum amount of MHOD. At 30°C and using phosphate buffer (0.1 M and pH=8), an initial substrate concentration of 10 mg mL-1 and … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some FluoroquinolonesHesham SalemSimple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first method was a spectrofluorimetric method in which samples of the studied drugs in 0.1 N H2SO4 showed native fluorescence at 450 nm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analytical Survey of Difficulty Faced in an Online Lecture During COVID-19 Pandemic Using CRISP-DMManmohan Singh, Vinod Patidar, Shaheen Ayyub et al.COVID-19 has greatly disturbed life in many ways and has changed the way we live. Various surveys have been conducted in different fields, and the teaching-learning process has been affected to a great extent. During this pandemic, various online tools and technologies have been available for guiding students without attending school. Many governments, corporations, and research fields have officially ordered … …Journal of Computer Science, Vol. 19, Issue 2 · 28 Jan 2023 · 6,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of two Different Culture Media on the Proliferation of Dental Pulp Stem Cells: Bovine Fetal Serum and Platelet LysateGiuseppe Cicero, Veena Nanda, Irene MartiniMesenchymal Stem Cells (MSCs) have been isolated from a variety of fetal and adult tissues and are considered an ideal source for cell-based therapy due to their unique properties such as multipotency and immunomodulatory functions. The aim of this work is to observe, analyze and investigate the morphology and proliferation of human dental pulp stem cells cultured in two different … …Current Research in Dentistry, Vol. 6, Issue 2 · 17 Sep 2015 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Shocks in Vibrationally Nonequilibrium Diatomic Gases at Various Distances from Critical Cross-Section of NozzleRydalevskaya Maria Alexandrovna, Voroshilova Yulia Nikolaevna, Uskov Vladimir NikolaevichThe high-temperature diatomic gas flows are considered in expanding nozzles under the conditions of a disturbance of the equilibrium distribution over vibrational levels of the molecules. The investigation of such flows is bound up with the problem of the inversion of the vibrational populations in the active mediums of molecular lasers. Under diverse values of the pressure overfall on coming … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractRouting Based Data Security in Mobile Ad Hoc Network Using Group Key ManagementE. Mohanraj, K. DuraiswamyProblem statement: A mobile ad-hoc network (MANET) is a self-organizing system of mobile devices followed an infrastructure less framework associated by wireless links. In MANET, there is a possibility of packet data to get lost or hacked by an attacker. So, to improve a secure communication over MANET from attackers, several techniques have been developed. The previous work developed to … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 6,697 accessesView PDFCite
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 PDFCite
