Research ArticleOpen accessIn the keywordsImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,636 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Autistic Phenotype Exhibits a Remarkably Localized Modification of Brain Protein by Products of Free Radical-Induced Lipid OxidationTeresa A. Evans, Sandra L. Siedlak, Liang Lu et al.Oxidative damage has been documented in the peripheral tissues of autism patients. In this study, we sought evidence of oxidative injury in autistic brain. Carboxyethyl pyrrole (CEP) and iso[4]levuglandin (iso[4]LG)E2-protein adducts, that are uniquely generated through peroxidation of docosahexaenoate and arachidonate-containing lipids respectively, and heme oxygenase-1 were detected immunocytochemically in cortical brain tissues and by ELISA in blood plasma. Significant … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 8,727 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalyzing Temperature-Dependent Thermal Properties of Biomaterials Using Machine Learning MethodsArmaghan Shalbaftabar, Kristen Rhinehardt, Dhananjay KumarThis research utilizes machine learning models ANN, Random Forest, and Decision Tree to predict material properties of Ti-based biomaterials, including Young’s modulus, density, thermal conductivity, and specific heat at various temperatures. Data was sourced using web scraping and Plot Digitizer, validated against literature, and analyzed in Excel. The ANN model achieved strong performance, with R² = 0.980874 for TiAl and … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 12 Sep 2025 · 4,640 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,552 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Treatment of the Mathematical Models for Water PollutionF. B. Agusto, O. M. BamigbolaTo evaluate the environmental impact of pollution, mathematical models play a major role in predicting the pollution level in the regions under consideration. This paper examines the various mathematical models involving water pollutant. We also give the implicit central difference scheme in space, and a forward difference method in time for the evaluation of the generalized transport equation. …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,386 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBIOTRANSFORMATION OF TEXTILE DYES: A BIOREMEDIAL ASPECT OF MARINE ENVIRONMENTR. S. Shertate, Prakash ThoratPresence of huge amount of salts in the wastewater of textile dyeing industry is one of the major limiting factors in the development of an effective biotreatment system for the removal of dyes from textile effluents. Large number of textile industries are located on the coastal areas due to ease of transport to the various places in world and help … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 7,385 accessesView PDFCite

Forty two adult male rats were assigned to seven groups, six animals each. The first group served as control and the second, third and fourth groups were … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 7 Dec 2013 · 6,748 accessesView PDFCite
Research ArticleOpen accessIn the keywordsScreening of Bacteria for Lactic Acid Production from Whey WaterVethakanraj Helen Shiphrah, Sayanti Sahu, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriLactobacilli have the property of converting lactose and other sugars to lactic acid through fermentation. So whey water, the greenish translucent liquid rich in lactose, vitamins, proteins and mineral salts, obtained as a by-product after the precipitation of cheese can be used as a substrate for Lactobacilli for lactic acid production which otherwise is a serious environmental pollutant when disposed … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 9,342 accessesView PDFCite
Research ArticleOpen accessIn the keywordsASSESSMENT OF SURFACE WATER QUALITY IN AN ARSENIC CONTAMINATED VILLAGEKumud C. Saikia, Susmita GuptaArsenic contamination of ground water has occurred in various parts of the world, becoming a menace in the Ganga-Meghna-Brahmaputra basin (West Bengal and Assam in India and Bangladesh). Recently arsenic has been detected in Cachar and Karimganj districts of barak valley, Assam, bordering Bangladesh. In this area coli form contamination comprises the major constraint towards utilization of its otherwise ample … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 31 Aug 2012 · 7,518 accessesView PDFCite
