Research ArticleOpen accessIn the abstractSimple Method of Purifying Humic Acids Isolated from Tropical Hemists (Peat Soil)Susilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopThe objectives of this study were: To investigate whether a purification period of HA isolated from Hemists peat soils could be reduced and to investigate whether distilled water could be used to purify HA isolated from Hemists peat soils. Standard procedures were used to extract and fractionate HA in a Hemists peat soil. The isolated HA was purified by suspending … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,151 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Simulation Tool to Model the Ground Level Concentrations of Green House Gases Emitted by Flaring in Petroleum Production in Kuwait OilfieldsKhaireyah Kh. AL-Hamad, V. Nassehi, A.R. KhanAir pollution and its effects on the ecosystem has been a source of concern for many environmental pollution organizations in the world. In particular climatologists who are not directly involved in petroleum industry sometimes express concerns about the environmental impacts of gas emissions from flaring at well heads. For environmental and resource conservation reasons, flaring should always be minimized as … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractNifH: Structural and Mechanistic Similarities with Proteins Involved in Diverse Biological ProcessesSurobhi Lahiri, Lakshmi Pulakat, Nara GaviniThe NifH protein is a subunit of the nitrogenase enzyme that catalyzes the reduction of atmospheric nitrogen to ammonia. This protein contains highly conserved regions including the nucleotide binding sites, metal center ligands and the Switch I and Switch II domains. A number of proteins have structural and mechanistic similarities as well as evolutionary relationships with the NifH protein, notable … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Metal Accumulator and Protease Secretor Microbes from East Calcutta WetlandSanhita Chowdhury, Madhusmita Mishra, V.K. Adarsh et al.Nine bacterial isolates were screened from different sites of East Calcutta Wetland, an ecosystem located at the eastern fringes of Calcutta. Other than being a biodiversity rich area, the important feature of this system is that it is a natural sewage treatment plant for the city of Calcutta. In addition to daily sewage including solid and soluble wastes, a considerable … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Variability of Soil Inorganic N in a Mature Oil Palm Plantation in Sabah, MalaysiaAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedThe identification and understanding of soil factors influencing yield variability of oil palm enable their efficient management. Soil samples were therefore collected from a fertilizer response trial on oil palm to study the spatial inorganic N distribution and some selected soil chemical properties as affected by long-term N fertilizer applications. The experiment was conducted on mature oil palms grown on … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,062 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Resource Synchronizer Mutual Exclusion Algorithm for Wired/Wireless Distributed SystemsAhmed Sharieh, Mariam Itriq, Wafa DbabatA mobile host has small memory, relatively slow processor, low power batteries, and communicate over low bandwidth wireless communication links. Existing mutual exclusion algorithms for distributed systems are not enough for mobile systems because of several limitations. In this study, a mutual exclusion algorithm that is more suitable for mobile computer systems is developed. The algorithm tends to minimize the … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractBridging from Cells to Cognition in Autism Pathophysiology: Biological Pathways to Defective Brain Function and PlasticityMatthew P. Anderson, Brian S. Hooker, Martha R. HerbertWe review evidence to support a model where the disease process underlying autism may begin when an in utero or early postnatal environmental, infectious, seizure, or autoimmune insult triggers an immune response that increases reactive oxygen species (ROS) production in the brain that leads to DNA damage (nuclear and mitochondrial) and metabolic enzyme blockade and that these inflammatory and oxidative … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractSugarcane Phenological Date Estimation Using Broad-Band Digital CamerasMobasheri, M. Chahardoli, J. Jokar, M. FarajzadehIn the agricultural industry, precision farming is the most important task that attracts lots of attentions. The health of the plant depends mostly on the amount of water in its access that can be estimated through vegetation indices. These indices can be extracted from satellite images through Image processing algorithms. The objective of this research was to provide an equation … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 7,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Stent Geometry on Phase Shift between Pressure and Flow Waveforms in Stented Human Coronary ArteryVahab Dehlaghi, Siamak Najarian, Mohammad Tafazzoli ShadpourShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Alterations of the phase shift between pressure and flow waveform created by a different stents were studied to compare the hemodynamic effects of stent design properties on restenosis in stented human coronary artery. Blood pressure waveforms were computed in three different sites, … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,252 accessesView PDFCite
