Research ArticleOpen accessIn the abstractSeasonal Distribution of Organic Carbon in the Surface Sediments of the Terengganu Nearshore Coastal AreaS. Hasrizal, B. Y. Kamaruzzaman, I. Sakri et al.Problem statement: The distribution of organic carbon in the surface sediment is a crucial indicator for current productivity in the ocean especially in the nearshore area. The difference of organic carbon in the surface sediment reflects the influence of current movement on the bottom sediment. Approach: This study was carried out to oversee the difference of organic carbon distribution during … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractFarmers' Use of Integrated Soil Fertility and Nutrient Management Practices for Sustainable Crop Production: A Field-level Study in BangladeshM. Golam Farouque, Hiroyuki TekeyaProblem statement: The most pressing problem for Bangladesh agriculture is the current state of gradual decreasing of soil fertility, stagnating crop yields and declining productivity in a range of food crops. According to crop production scientists, Integrated Soil Fertility (ISF) and Nutrient Management (NM) is an advanced approach that can serve as a remedy to improve crop yields and to … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Mathematics Web-Based Learning in SchoolsMansoor Al-A’aliTeaching Mathematics to intermediate school boys is a challenging process which can greatly benefit from software technology and web-based learning. In this research we study the difficulties and opportunities of using this technology in teaching Mathematics to 13 year old boys studying Mathematics at school. For students' we identify the basic requirements at home, e.g., Mathematics computer software packages, availability … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,268 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Classification Scheme for Efficient Retrieval of ComponentsC. V.G. Rao, P. NiranjanReuse is the key paradigm for increasing productivity and quality in software development. To be able to reuse software components, whether it is code or designs, it is necessary to locate the component that can be reused. Locating components, or even realizing they exist, can be quite difficult in a large collection of components. These components need to be suitably … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Thermostable α-Amylase Producing Natural Variant of Bacillus spp. Isolated From Soil in IranIraj Rasooli, Shakiba D. A. Astaneh, Hojjat Borna, Kamal A. BarchiniThermophilic processes appear more stable, rapid and less expensive and facilitate reactant activity and product recovery. Amylases have a quarter of the world enzyme market and thermostable a-amylases possess extensive commercial applications. Since little work has been done on strain isolation, growth and enzyme yield optimization, the level of thermophilic enzyme production remains relatively low. Therefore, large scale exploitation of … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,907 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Infrastructure Development on Income Generation: A Study on Jamuna Bridge Project in BangladeshShaikh MoniruzzamanThis research is an attempt to examine the impact of infrastructure development on income generation in the north eastern region of Bangladesh which enjoyed a wide range of amenities after the construction of Jamuna Bridge in 1998. The application of 'difference in difference estimator' using the pooled household level income data of the treatment and control area in the pre … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Persistence Framework-Based Rapid Application Development Toolkit for Web Application DevelopmentChoon H. Choo, Sai P. LeeSoftware systems must be delivered quickly in order to respond to today's rapid changing business environments. Persistence framework was introduced to overcome the problem of object-relational impedance mismatch, occurred in most enterprise applications that need access to a relational database. However, most of these persistence frameworks are difficult to configure and use, thus do not really contribute much to the … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrace Metal Effect on Hydrogen Production Using C.acetobutylicumHisham Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffThis study was carried out to study the effect of trace metal addition for hydrogen production The results show that this bacterial need a selected nutrient with selected concentration. The optimum parameters for cultivation were at initial pH of 7.0 and temperature of 30°C. Trace metal addition to the new medium showed that only iron enhanced the H2 yield.
