Research ArticleOpen accessIn the abstractA Review of the Mechanisms of Faecal Coliform Removal from Algal and Duckweed Waste Stabilization Pond SystemsE. D.O. Ansa, E. Awuah, A. Andoh et al.The use of eco-technologies for wastewater treatment such as algal and duckweed-based pond systems is becoming popular in developing countries owing to its affordability and efficiency of pathogen removal in warm climates. The pathogen removal mechanisms of these treatment systems however is still not clearly understood and existing knowledge is also scattered in journals and books of different disciplines. The … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 5 Apr 2015 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat Transfer Numerical Analysis of a Thermochemical Solar ReactorA. Vázquez-Rodríguez, J. R. Varela-Ham, R. Avalos-Zuñiga et al.In this study a 2D transient temperature distribution in a one-dimensional thermochemical solar reactor of gas-particles is presented. The gas-particles medium is contained in a reactor where an endothermic chemical reaction of some oxide-metal at high temperature is expected to be occurred. The reactor receives the concentrated solar power on the reactor walls, or directly to the gas-particles medium. As … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 6,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF PUERPERAL METRITIS ON HOLSTEIN COWS PRODUCTIVE, REPRODUCTIVE VARIABLES AND CULLING RATESA. Dawod, Byeng R. MinThe objective of the study was to determine the effect of puerperal metritis prevalence in high yielding Holstein cows on productive (305 days, actual milk yields), reproductive (days to first estrus, days open and services per conception) variables and culling rates. Throughout the study, 2885 dairy records were collected from high yielding private Holstein dairy farm (average milk yield was … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 12 Nov 2014 · 6,950 accessesView PDFCite
EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of the Thermal Comfort of Different Building Materials in Sana’aMousa Ahmed Alhaddad, Zhou Tie JunThis study describes the impact of alternative building material envelope systems on the overall thermal performance of four selected materials used in Sana’a, Yemen. These systems included adobe, brick, stone and concrete block. After thorough on-site investigation and data collection, the information, along with regional weather data were input into the Ecotect energy simulation software for thermal performance evaluation. The … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 25 Jan 2013 · 8,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Splay Leg Syndrome in Piglets: A ReviewVassilis G. PapatsirosProblem statement: The splay leg syndrome is the major congenital cause of lameness in suckling piglets. It is characterized by a temporarily impaired functionality of the hind leg muscles immediately after birth, resulting in an ability to stand and walk. Etiology and pathogenesis is complex and remain still poorly understood. Approach: The aim of the present study is to perform … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 19 Jul 2012 · 10,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoreless Winter Characteristics Observed with Global Positioning System Receivers over Antarctic and Arctic RegionsWayan Suparta, Faizatul Noor Abu Bakar, Mardina AbdullahProblem statement: The most recent warming trends occurred during the winter in Polar Regions had been attracted many researchers to study its impacts, which might affect the sensitivity of climate prediction in both regions, as well as on a global basis. Approach: The aims of this study were to observe the characteristics of coreless winter events using the GPS meteorology … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 22 Jun 2012 · 7,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalynological Studies of Sediments from North Chioma-3 Well, Niger Delta and its Palaeoenvironmental InterpretationsOlugbenga Ebenezer Ige, Kalyani Datta, Kanak Sahai, Krishna Kumar RawatProblem statement: The Niger Delta Nigeria stands among the world's best-studies delta complexes but its superficial deposits are among the poorest known publicity. In spite of continuous oil prospecting production in the area, there is still a paucity of published information and data on the palynology of the Niger Delta. This study aimed at reconstructing the palaeoenvironments of the Niger … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,884 accessesView PDFCite
