Research ArticleOpen accessIn the abstractTracking Error Analysis of a Rotation-Elevation Mode HeliostatOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanFor the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically analyze the image movement and to find out the error of the parameters. In the simulation program, ray-tracing method was applied to work out the central point position … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organoclay from Sodium Montmorillonite and Fatty Hydroxamic AcidsWisam H. Hoidy, Mansor B. Ahmad, Emad A. Jaffar Al Mulla, Nor Azowa Bt IbrahimProblem statement: Sodium Montmorillonite (Na-MMT) has been modified via cation exchange reaction using Fatty Hydroxamic Acids (FHAs) synthesized from palm oil as a surfactant to produce organoclay which is used to prepare polymer nanocomposites. Approach: Basal spacing, functional groups identification and thermal stability of this Organo-Montmorillonite (OMMT) were characterized using X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy and Thermogravimetric … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 9,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractED-XRF Analysis of Total Suspended Particulates from Enamelware Manufacturing IndustryJ. A. Sonibare, F. A. Akeredolu, O. Osibanjo, I. LatinwoConcentration and elemental composition of the total suspended particulates (TSP) emitted due to manufacturing activities of an enamelware industry in Lagos, Nigeria were investigated. Gravimetric method was used in mass concentration determination and an energy dispersive x-ray fluorescence (ED-XRF) analyzer was employed in the multi-elemental analysis. The Federal Ministry of Environment (FMENV, Nigeria's environment regulating body) set limit of 250 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Receptor Activator of Nuclear Factor Kappa B (RANK) and Receptor Activator of Nuclear Factor Kappa B Ligand (RANKL) in Osteoporosis Risk: Gene Polymorphism and Soluble RANKL Level in Indonesia Post-Menopausal WomenLuluk Yunaini, Dwi Anita Suryandari, Linda Kusdhany et al.Hormonal changes in postmenopausal women may increase osteoclastogenesis that can lead to increased risk of osteoporosis. Receptor Activator of Nuclear factor Kappa B (RANK) and Receptor Activator of Nuclear factor Kappa B Ligand (RANKL) have an important role in osteoclastogenesis that involve in the regulation of bone resorption. In this study, we analyzed the Single Nucleotide Polymorphism (SNPs) within the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 27 Sep 2018 · 8,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Characterization of Chemical Constituents, Cytotoxicity, Antibacterial and Antioxidant Activity of the Compounds from Leptadenia hastata Roots Extract ByIsaac John Umaru, Hauwa A. UmaruThe aim of this work was to extract, isolate and characterise the chemical constituent from Leptadenia hastata roots. Fresh roots were washed and dried and was subjected to sequential maceration in polar and non-polar solvents. And introduced into rotary evaporator to concentrate the extract. Isolated compound was subjected to Thin Layer Chromatography and spectral analysis such as column and UV-Visible … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 24 Dec 2019 · 7,959 accessesView PDFCite
EditorialOpen accessIn the abstractProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,854 accessesView PDFCite

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 PDFCite
