Research ArticleOpen accessIn the abstractGeochemistry of Siloam and Tshipise Geothermal Springs, Limpopo Province, South AfricaOlatunde Samod Durowoju, John Ogony Odiyo, Georges-Ivo Ekosse EkosseGeothermal springs are natural geological phenomena that occur throughout the world, and South Africa (SA) is endowed with several springs of this nature. Most of the geothermal springs in SA (31%) are found in Limpopo Province. Assessment of geochemistry of Siloam and Tshipise geothermal springs were undertaken during 2014 winter (May – July) and summer (October – December) seasons. Water … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Mar 2018 · 8,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Temperature and Precipitation on Global Mangrove Rhizophora Species DistributionAroloye O. Numbere, Gerardo R. CamiloClimate change influences the distribution of mangroves towards tropical or temperate regions of the world. We hypothesized that Rhizophora species organized along complex spatial and temporal temperature and precipitation gradient. To determine the affinity of different mangroves with climatic parameters, the response of eight Rhizophora species to seven climatic parameters (i.e., annual mean temperature, annual precipitation, maximum temperature of warmest … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 5 Oct 2017 · 8,259 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 abstractBroken Character Image Restoration Using Genetic Snake Algorithm: Deep Concavity ProblemQusay Omran Mosa, Mohammad Faidzul NasrudinActive contours also known as snakes became a familiar and widely used in the field of image segmentation and restoration of historical documents in last few decades. Gradient Vector Flow (GVF) snake successes in overcome of converge to boundary concavities which represents the drawback of traditional snakes. Deep concavity problem it has become Obstacle faced GVF snake when restoring broken … …Journal of Computer Science, Vol. 12, Issue 2 · 22 Mar 2016 · 7,350 accessesView PDFCite
Review ArticleOpen accessIn the abstractEffects of Intermittent Artificial Circulation in Summer Months on Chlorophyll a Concentration in a Small Eutrophic ImpoundmentAnusha Balangoda, Shafiqur Rahman, G. PadmanabhanImpact of artificial circulation on total algal biomass (as chlorophyll a integrated over depth) in a small eutrophic impoundment in the Northern Great Plains, was monitored over three consecutive summers. Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and non-aerated conditions at four sampling locations. Aeration destratified the water column, which resulted in … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 14 Nov 2015 · 7,303 accessesView PDFCite
Case ReportOpen accessIn the abstractSteady State Groundwater Flow Modeling of an Ex-Landfill Site in Kuala Lumpur, MalaysiaMustapha Atta, Wan Zuhairi Wan Yaacob, Othman Bin JaafarEffective and rational management of groundwater resources require adequate information on the groundwater flow interactions with surface water and chemical species in the flow regime. The hydrologic conditions beneath the unlined ex- landfill site in Jinjang Kuala Lumpur were investigated to understand the groundwater flow and geochemical setting in which contaminants transport in the groundwater may occur in the ex-landfill. … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 30 Oct 2015 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreliminary Evaluation of a Permeable Reactive Barrier for Reducing Groundwater Nitrate Transport from a Large Onsite Wastewater SystemCharles Humphrey, Sushama Pradhan, Eban Bean et al.A permeable reactive barrier was installed between a large Onsite Wastewater System (OWS) and a monitoring well located down-gradient from the OWS. Groundwater samples from the well had shown elevated and increasing concentrations of NO3--N (>20 mg L-1 for 2 years). The barrier was constructed using woodchips from various tree species that were placed in a trench excavated to approximately … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 25 Aug 2015 · 7,372 accessesView PDFCite
HypothesisOpen accessIn the abstractReal-Time Automatic Inspection System for the Classification of PCB Flux DefectsAng Teoh Ong, Aouache Mustapha, Zulkifilie Bin Ibrahim et al.Automatic inspection based on a real-time machine vision system may serve as substitute for the manual human visual inspection of flux defects in Printed Circuit Boards (PCBs), which often cause damage on the board in the form of corrosions that harm the assembly. The concept of automatic inspection contributes to the improvement of the manufacturing quality of PCBs and facilitates … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 25 Aug 2015 · 8,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractFUSION OF COLOR AND MODIFIED WEBER’S LAW DESCRIPTOR BASED HUMAN SKIN DETECTIONC. Prema, D. ManimegalaiSkin detection in images or videos plays a vital role in a wide range of image processing applications like face detection, face tracking, gesture analysis, human-computer interaction etc. Due to its high processing speed and invariant against rotation, it has received significant interest in pattern recognition and computer vision. The robustness of skin detection using color information depends on real … …Journal of Computer Science, Vol. 10, Issue 9 · 19 Apr 2014 · 6,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractRnai Induced Wing Modification in Leon Mutant Drosophila: A Developmental AnalysisSandeep Satapathy, Cheng Ting ChienThe precision of growth of an animal is meticulously regulated by extrinsic and intrinsic factors, with focus on maintenance of organismal homeostasis. The clue to change in physiology or metabolism of an organism, at times can be derived from the changes in phenotypes. In the Drosophila melanogaster model system, GAL 4-overexpressed RNAi driver males (Mini-White Marker), targeted against specific genes, … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 6,717 accessesView PDFCite
