Research ArticleOpen accessIn the abstractPreventive Effect of Marsileacrenata Leaves and Stalks Juices Against Urolithiasis Showed by Improving of Kidney FunctionSri MurwaniNowadays urolithiasisis still as a major problem in pet animals, particularly for dogs and cats. Urolithiasisis caused by formation of crystals in the urinary tract that inhibit the process of urination. It is frequently as an impact of dry food given regularly, keeping animals in a place so that the movement of the animal becomes restricted, lack of water intake, … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 10 Feb 2016 · 9,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractRaman Spectroscopy of Protein Crystal Nucleation and GrowthPechkova Eugenia, Maksimov, Georgy et al.Using Raman spectroscopy and the lysozyme as model system, we investigate the differences in protein conformation before and after Langmuir-Blodgett nanotemplate-induced crystal nucleation and growth. It was found, that the main difference in lysozyme conformation is associated to the higher amount of S-S bonds in lysozyme of LB crystals, probably in C-end of protein, resulting in the higher stiffness of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 8 Dec 2014 · 8,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Evaluation of Coulomb Lattice Sums of Charge SystemsV. Ilyin, A. Brandt, I. SuwanProblem statement: Due to the long range nature of interactions of the N-body systems, direct computation of the Coulomb potential energy involves O(N2) operations. To decrease such complexity, a simple Multilevel Summation method has been developed. Approach: In the frame of the Multilevel Summation method, the two-body interaction is decomposed into two parts: a local part and a smooth part. … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 11 Sep 2012 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractNanocrystalline Zn0.9Mn0.1S Thin Film: Case StudiesMohammad Syuhaimi Ab-Rahman, Noor Azie Azura Mohd Arif, Abang Anuar Ehsan, Sahbudin ShaariProblem statement: The high quality of ZnS:Mn nanocrystals is important in nanotechnology industries. The perfect chemical procedure is significant to produce the best of nanocrystals. Hence, this research is concern on the good chemical method in processing manganese doped zinc sulphide nanocrystals. Approach: For the first step, Mn doped ZnS nanocrystals were synthesized by using sol gel spin coating method. … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractScale Formation Due to Water Injection in Malaysian Sandstone CoresAmer Badr Bin Merdhah, Abu Azam Mohd YassinProblem statement: Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Approach: This study was conducted to investigate the permeability reduction caused by deposition of calcium, strontium and barium sulphates in sandstone cores from mixing of injected Malaysian sea waters (Angsi and Barton) and formation water … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Al3Fe5O12 Cubic Structure by Extremely Low Sintering Temperature of Sol Gel TechniqueNoorhana Yahya, Ramadan A.H. Masoud, Hanita Daud et al.Problem statement: Fabrication of nano materials particularly nano inductors at low sintering temperature remains a challenge. This study was carried out as our initial response to obtain a nano-size inductors, which is aluminium iron garnet using low sintering temperature. Approach: The aluminum iron garnet (Al3Fe5O12) nano crystals were prepared by sol-gel technique. The starting solution is a mixture of iron … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetoxification of Heavy Metal Contaminated SoilsFloarea Damian, Gheorghe DamianThe concentration of the heavy metals in the soils from the strong affected zones because of the mining and metallurgical industry, Baia Mare and Zlatna (Romania), is significant due to the high values of the contents and association of the four metals Pb, Cu, Zn, Cd. The efficacy of the natural zeolites in heavy metals immobilization from the studied soils … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,233 accessesView PDFCite
