Research ArticleOpen accessIn the abstractOptical Characterization of Lead-Bismuth Phosphate GlassesH. A.A. Sidek, M. Hamezan, A. W. Zaidan et al.Systematic series of lead-bismuth phosphate glasses, where PbO, Bi2O3 and P2O5 content change for every series based on their weight percentage have been prepared. The optical properties were measured and their amorphous nature was confirmed by X-ray diffraction technique. Both experiments were conducted at room temperature. The fundamental absorption edge for all the glasses was analyzed. The values of refractive … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,434 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Evaluation of Aqueous and Freeze Dried Antigen for Sero-diagnosis of VL and PKDL Cases by DATSanjiva Bimal, Shubhankar K. Singh, P. K. Sinha et al.The efficacy of aqueous and freeze dried (FD) antigen was evaluated by direct agglutination test (DAT) for sero-diagnosis of visceral leishmaniasis. A total of 16 samples collected from 5 confirmed Kala-azar (KA) cases, 6 cases 2 each of filariasis, malaria, leprosy and 5 non-endemic healthy subjects were used in determination of cut off titre of both the antigens in DAT. … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,834 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,586 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of the Ozonation Pre-treatment for Biodegradation of Aqueous Solutions of Methyltert-Butyl EtherM. Sadeghi, A. Mesdaghinia, A. Badkoubi et al.The effectiveness of ozone treatment for improving the biodegradability of recalcitrant pollutants has been proved by investigating the ozonation reaction of Methyl tert-butyl ether (MTBE) a bioresistant gasoline oxygenate. Laboratory scale experiments have been carried out, at room temperature, by bubbling, for 120 min, ozonated air (3.4 ppm min-1 ) into 3 liter of an alkaline (pH=11.5) aqueous solution (100 … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,463 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDesign IoT Based Smart Electricity Power Saving University: Analysis from a Lecture HallShanmuganathan Vasanthapriyan, Viduni RandimaManaging and controlling the electricity consumption in a productive manner is a red hot topic in today’s world. Many countries have considered this problem and they have suggested automate systems to overcome this problem. Since, Sri Lankan has not used such kind of automated system to control the electricity power consumption, our system will be a suitable solution for that. … …Journal of Computer Science, Vol. 15, Issue 8 · 8 Aug 2019 · 8,478 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,934 accessesView PDF Cite
