Research ArticleOpen accessEvery word in the titleElectronegativity, Interaction Parameter and Electronicpolarizability for Bisumth Borate Metal GlassesEl-Sayed Moustafa, Farid ElkhatebProblem statement: In the present work, we applied the concept of the optical electronegativity to predict basic properties of some ternary oxide glasses. Recently Optical electronegativity of many binary oxide glasses has been evaluated on the basis of two different parameters, the linear refractive index and the energy gap, which have demonstrated remarkable correlation. Approach: In this study, the refractive … …Physics International, Vol. 2, Issue 1 · 1 Dec 2011 · 7,312 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Estimation of the Oxide Ion Polarizability for B2O3-Li2O-Mo Glass SystemEl-Sayed Moustafa, Farid ElkhatebProblem statement: Recently Optical electro negativity of many binary oxide glasses has been evaluated on the basis of two different parameters, the linear refractive index and the energy gap, which have demonstrated remarkable correlation. Approach: In the present study, an improvement method to estimate the oxide ion polarizability through the average optical electro negativity for the lithium borate metal (Mo) … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 2 Feb 2012 · 7,065 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Study of the Effects of Soil Salinity on the Growth and Development of Maize (Zea Mays L.) by using Sentinel-2 ImageryShakhislam Uzakbaevich Laiskhanov, Zhassulan Maratuly Smanov, Kulyash Duisenbaevna Kaimuldinova et al.Salinization of soil cover and the constant increase in their area have become one of the most pressing problems year after year for irrigated agriculture regions. The degradation processes caused by the salinity of soils negatively affect the growth and development of food crops. Therefore, this study focused on the effects of soil salinity in the midstream of the Syrdarya … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Aug 2022 · 6,257 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis and Biological Evaluation of 6-Hydroxy-4-Methyl-5,7-(Bis-p-ChlorophenylAzo) CoumarinDalal M. Ibrahim, Juliana Jumal, Farah Wahida Harun6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarinhas been synthesized and characterizedby CHN elemental analysis, FTIR, 1H-NMR-spectroscopy andmass-spectral data. Cytotoxic screening by MTT assay was carried out on the compoundagainst breast cancer cells. The overall results from preliminary screeningprogram revealed that the cell proliferation was highly inhibited by 6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarin with the value of 2.81%, at concentration of 30 µg mL-1 comparedwith the untreated control cells and also … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 21 Dec 2015 · 7,670 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHydrophobic, Polar and Hydrogen Bonding Based Drug-Receptor Interaction of TetrahydroimidazobenzodiazepinonesV.K. Sahu, A.K.R. Khan, R.K. Singh, P.P. SinghAnti-HIV drug discovery has been increasingly focusing on HIV-1-RT (reverse transcriptase) as a potential therapeutic target. Tetrahydroimidazobenzodiazepinone (TIBO) belongs to non-nucleoside group of reverse transcriptase inhibitors (NNRTIs). A computational chemistry study has been performed on a series of tetrahydroimidazo-benzodiazepinones as HIV-1-NNRT inhibitors. Problem statement: In order to search out new drug of desired activity from the lead compounds, there was … …American Journal of Immunology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,837 accessesView PDF Cite
