Review ArticleOpen accessEvery word in the titleSelected Genotoxic Impurities Profiling During WFI Qualification to Control Carcinogenesis in Large Volume ParenteralsMohabbat UllahWater For Injections (WFI) which is the main vehicle of Large Volume Parenterals (LVPs) should be free from trace amount of genotoxic impurities. This review gives emphasis on quantification of genotoxic trace metals during qualification of WFI in LVPs manufacturing unit. According to ICH guidelines, impurities related to drug substances are classified into three main categories: Organic impurities, inorganic (elemental) … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 1 · 27 May 2015 · 7,708 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLocalization of Implanted Impurities in SiliconM. Jadan, Jihad S.M. AddasiLocalization of implanted boron impurities at the nodes and interstitial of silicon depending on the implantation current density has been studied by the X-ray diffraction and astrophysical methods. A shares of the impurity at the lattice sites increases with growing current density due to the instantaneous vacancy concentration and suppression of the impurity displacement from the sites by silicon interstitial. …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,712 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePurification of Natural Gas with Impurities using Membrane Processes: Parameter EstimationN. W. Jusoh, K. K. Lau, A. M. ShariffProblem statement: Membrane processes have received a significantly high attention on natural gas separation processes since this technology provides higher operating and cost advantages as compared to other technologies. One of the major problems related to natural gas separation using membrane is the existence of feed impurities including CO2, heavy hydrocarbon and water. Approach: Hence, mathematical model that is able … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 22 May 2012 · 8,426 accessesView PDFCite
Review ArticleOpen accessIn the abstractAssessing Protein PurityShiva Siddappa, Liang-Yin Ke, Chu-Huang Chen, Gopal Kedihithlu MaratheDetermination of protein purity is crucial, as proteins are frequently used as therapeutic agents and reagents in many biochemical reactions. Additionally, purified protein is necessary for biophysical and structural studies. Assessing protein purity involves examining for impurities or demonstrating their absence. In our experience, a satisfactory answer is seldom obtained when biochemistry students are asked a common question on how … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 9 Feb 2026 · 1,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractWorking Process Analysis and Parameter Optimization of Millet Hill-Drop Seed Metering DeviceTao Chen, Shujuan Yi, Yifei LiDue to the small size, light weight, and impurities of millet, the existing seeders have poor quality when sowing millet, this study analyzed the working process of the pneumatic-mechanical combined seed metering device, established the equations of seed movement in the seed filling zone, seed cleaning up zone, seed carrying zone and seed dropping zone by dynamic theory. The theoretical … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 12 Aug 2023 · 6,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Assessment of Dust-Holding and Oxygen-Producing Productivity of Hawthorns in KazakhstanBotagoz Kentbayeva, Zhadyra Baigazakova, Mukhtar Baybatshanov et al.The research aimed to study the oxygen productionand the dynamics of the leaf blade dust-collecting ability of hawthorns growingin contrasting ecological and climatic areas. Hawthorns in urban green spacesare a fairly common tree species and play an important hygienic role inpurifying the atmospheric air from dust and harmful impurities and havesufficient oxygen productivity. Hawthorn trunks ensure 70% of all oxygenproductivity … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 9 Sep 2022 · 5,448 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Data Mining Classifiers on Sunflower Edible Oil Bleaching Process: A Comprehensive Comparative AnalysisÖmer Nedim Kenger, Eren ÖzceylanSunflower oil is widely used as edible oil. It is commonly extracted by solvent extraction method from the sunflower seed. After extraction, crude sunflower oil is obtained. Crude sunflower oil has some undesirable impurities and dark colors. These impurities and dark colors require removal. The bleaching process is applied to remove the color. The bleaching earth is used in the … …Journal of Computer Science, Vol. 17, Issue 4 · 30 Apr 2021 · 6,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Novel Thermo-Chemical Treatment on Bending Strength of Laminated GlassAjitanshu VedrtnamThe science of thermal and chemical treatment of glass is well documented. The Laminated Glass (LG) is usually not treated as either treated glass is used during production or lower melting temperature of interlayer does not allow the treatment. The present work reports the novel methods of thermo-chemical treatment of LG having annealed soda lime glass plies. Five thermo-chemical treatments … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 29 Mar 2018 · 6,973 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Genetic Purity of Parental Lines of Hybrid Rice Using DNA-Based MarkersSunil Bhavsar, Twinkle Solanki, Suchita Amin, Neeru JainAssessment of hybrid seed genetic purity is one of the most important quality control parameters in hybrid seed production. With the objective of replacing the GOT with DNA based assays, Cytoplasmic Male Sterile (CMS), restorer and hybrid lines have been screened by means of microsatellite and Sequence Tagged Site (STS) markers. Cytoplasmic Male Sterile (CMS) lines often get contaminated with … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 13 Jun 2015 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDFCite
