Research ArticleOpen accessIn the abstractA Prescriptive Specialized Learning Management System for Academic Feedback towards Improved LearningAnnette van der Merwe, Tiny du Toit, Hennie KrugerThe dynamic nature of technological advances is causing changes in many fields and especially in tertiary education. Student numbers are increasing annually and institutions need to maintain education quality whilst ensuring student retention. A specialized learning management system (SLMS) was developed in this study that provides students with comprehensive feedback which will enable them to better manage their academic performance. … …Journal of Computer Science, Vol. 14, Issue 10 · 24 Oct 2018 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Oxidative Stress during Pregnancy on Obstetric Pathology Development in High-Yielding Dairy CowsInna Ventsova, Vladimir SafonovThe study aimed to examine the processes of oxidative stress and their intensity depending on the state of the antioxidant system in dairy cows. The study was conducted in 2018-2019 on the territory of the Druzhba breeding factory (Voronezh region, Russia) and involved 154 cows divided into 4 groups. Group 1 consisted of healthy animals (n = 83). Group 2 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 19 Jan 2021 · 6,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Probiotics on Coccidia, H. Contortus and Markers of Infection in GoatsKwaku Barima Gyenai, Mulumebet Worku, Mehrdad Tajkarimi, Salam IbrahimImmunostimulants can induce nonspecific resistance against parasites. The use of probiotics to control development of animal gastrointestinal parasites could help reduce the risks of infestation. In this study, we investigated the effects of probiotics administration on gastrointestinal parasites coccidia, H. contortus and markers of infection. A cocktail of probiotics mix including Bifidobacterium longum, Bifidobacterium breve, Lactobacillus acidophilus, Lactobacillus reuteri and … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 3 · 29 Jul 2016 · 9,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransformation or Transgression? Institutional Habitus andWorking Class Student IdentityTina Byrom, Nic LightfootProblem statement: Whilst evidence continues to highlight disparity in Higher Education (HE) participation rates across social groups, there continues to be small numbers of young people from social groups 4-7 choosing to go to university. However, university experience varies across the different social groups and differing social positions appear to influence the higher education institution students apply to and secure … …Journal of Social Sciences, Vol. 8, Issue 2 · 18 Feb 2012 · 9,615 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Diurnally Cyclic Temperature on the Performance of a Continuous Mix Anaerobic DigesterAbdel E. Ghaly, Mariam T. Al HattabProblem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 19 Jan 2012 · 9,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopmental Design of Anaerobic Wetland System for Mining Waste Water TreatmentMuhammad Aqeel Ashraf, Mohd. Jamil Maah, Ismail YusoffProblem statement: Tin mining is one of the oldest industries in Malaysia that have started since 1820s. These mining activities have resulted in about 13,700 hectors of tin tailings throughout the peninsula. These tailings have created numerous environmental problems such as threat to natural reserves due to landscape changes, damage to natural drainage, pollution and destruction of natural habitats. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 10 Oct 2011 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Dietary Curcumin on Rumen Fermentation, Macronutrient Digestion and Nitrogen Balance in Beef CattleT. Vorlaphim, M. Phonvisay, J. Khotsakdee et al.Abstract: Problem statement: Previous studies have shown that curcumin has antibacterial activity. It was hypothesized that the feeding of curcumin to ruminants may disturb rumen function and affect macronutrient digestibility and nitrogen utilization. Approach: In an experiment with Latin-square design, beef cattle were fed rations consisting of urea-treated rice straw and concentrates without or with 0.1 or 0.2% added curcumin. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 9,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteractive Effects of the Feeding of Leucaena Leaves and Curcumin on Macronutrient Digestion and Nitrogen Balance in Beef CattleC. Yuangklang, J. Khotsakdee, K. Vasupen et al.Abstract: Problem statement: The feeding of curcumin to beef cattle has been shown to increase nitrogen retention and decrease the apparent digestibility of acid detergent fiber in beef cattle. It was suggested that there could be interactions between the effects of curcumin and the composition of the ration. Approach: In this study with beef cattle, concentrates without or with curcumin … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractRenal Actions of Neutral Endopeptidase Inhibition in Rats with Chronic Heart FailureAmr M. Abbas, Ayman Z. Elsamanoudy, Adel ZalataProblem statement: We aim to evaluate the effects of acute and chronic inhibition of Neutral EndoPeptidase (NEP), by ONO-9902, on plasma and renal NEP gene expression, hemodynamic and renal parameters in rats with Chronic Heart Failure (CHF) following left Coronary Artery Ligation (CAL). Approach: Forty eight male Sprague-Dawley rats (220-240 g) were divided into sham and CAL groups.

Research ArticleOpen accessIn the abstractReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDFCite
