Research ArticleOpen accessIn the abstractThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,001 accessesView PDF Cite

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 · 7,630 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural Evidences of Hepatitis B Infection in Human Liver Biopsies Disclose Complex Assembly and Morphogenesis Pathways for Hepatitis B VirusViviana Falcon, Ivon Menéndez, Nelson Acosta-Rivero et al.Despite of recent advances on acknowledge of hepatitis B virus (HBV) structure and biology, little is known about the morphogenesis and release of virions. In this study, the ultrastructural analysis of HBV components in liver biopsies from chronically HBV-infected patients disclosed complex assembly and morphogenesis pathways for HBV. HBV core (HBcAg) and surface (HBsAg) antigens were specifically identified in all … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,094 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,909 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMorphological and Structural Reaction of Avena sativa Seedlings to the Effects of Nano and Microparticles of ZincArailym Serikbai, Aidar Aitkulov, Anna Stanco et al.Kazakhstan has a well-developed mining and metallurgical industry, which produces macroand nanoparticles of heavy metals, including zinc emitted to the environment. The nanoscale particles have a different biological activity, which requires some additional research. The effects of various concentrations of zinc macroparticles and nanoparticles on the anatomical structure of oat seedlings (Avena sativa L.) and their accumulation in vegetative organs … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 9 Jul 2024 · 4,410 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparison of Anatomical Characteristics and Phytochemical Components Between Two Species of Hedysarum (Fabaceae)Adil Kusmangazinov, Meruyert Sakenovna Kurmanbayeva, Irina Zharkova et al.Hedysarum L. is one of the large genus of the Fabaceae Lindl. family, consisting of 200 species. Species in the genus Hedysarum are valuable forage and medicinal resources. In this study, we studied Hedysarum theinum Krasnob and Hedysarum neglectum Ledeb growing in the western Altai of Eastern Kazakhstan. H. theinum is a perennial, herbaceous, valuable medicinal plant, a rare species, … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 14 Jun 2023 · 5,837 accessesView PDF Cite
