Research ArticleOpen accessIn the abstractEffect of Skidding Operations on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: There is still lack of a study that compares the soil carbon storage of kuda-kuda skidding system and excavator skidding system in tropical peat swamp forests. The objective of this study was to determine whether skidding operations affects soil carbon storage of a tropical peat swamp forest. Approach: Soil sampling was conducted on two different plots (0.3 ha … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving the State Assignment Problem Using Stochastic Search Aided with Simulated AnnealingWalid M. AlyProblem statement: Solving the state assignment problem means finding the optimum assignment for each state within a sequential digital circuit. These optimum assignments will result in decreasing the hardware realization cost and increasing the reliability of the digital circuit. Unfortunately, the state assignment problem belongs to the class of nondeterministic polynomial time problems (NP complete) which requires heavy computations. Different … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 6,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Nickel Exposure and the Level of Carcinoembryonic Antigen among Welders in an Automotive PlantChiang Lee Juan, Shamsul Bahri Mohd Tamrin, Syazwan Aizat Ismail et al.Background: Study on the effect of nickel exposure in the occupational setting and its association to carcinoembryonic antigen (CEA) had been studied before. Questions were raised whether the result from previous study would also show the same pattern of the urinary nickel concentration in this study. Objective: A cross-sectional study was conducted to determine the association between urine nickel concentration … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractCommunity Participation in Watershed Management ProgramsReza Bagherian, A. S. Bahaman, A. S. Asnarulkhadi, Shamsuddin AhmadProblem statement: Several studies in other countries had shown the influence of socio demographic, knowledge, satisfaction and attitudinal factors in level of community participation in development programs. The question here is, whether these factors would also be effective on community participation in WMP in Iran? Objective: Determine the factors which are influence community participation in order to enhance their participation … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 8,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Control-Oriented Coverage Metric and its Evaluation for Hardware DesignsShireesh Verma, Kiran Ramineni, Ian G. HarrisProblem statement: Dynamic verification, the use of simulation to determine design correctness, is widely used due to its tractability for large hardware designs. A serious limitation of dynamic techniques is the difficulty in determining whether or not a test sequence is sufficient to detect all likely design errors. Coverage metrics are used to address this problem by providing a set … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhy College or University Students Hate Proofs in Mathematics?Mbaïtiga ZacharieProblem Statement: A proof is a notoriously difficult mathematical concept for students. Empirical studies have shown that students emerge from proof-oriented courses such as high-school geometry, introduction to proof, complex and abstract algebra unable to construct anything beyond very trivial proofs. Furthermore, most university students do not know what constitutes a proof and cannot determine whether a purported proof is … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of the Prostatic Fluid from the First and Third Fractions of the Ejaculates on the Cryosurvival of Poodle Dog SpermHideaki Yamashiro, Kaori Narita, Satoshi Sugimura et al.Problem statement: Two experiments were conducted to determine the effect of the prostatic fluid from the first and third fractions of the ejaculates on the freezability of poodle dog sperm. Approach: The ejaculates from 2 trained poodle dogs were collected. Effect of prostatic fluid from the first and third fractions of ejaculates on cryosurvival of dog sperm was examined. SDS-PAGE … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 7,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient Stability Assessment of a Power System Using Probabilistic Neural NetworkNoor Izzri Abdul Wahab, Azah MohamedThis study presents transient stability assessment of electrical power system using Probabilistic Neural Network (PNN) and principle component analysis. Transient stability of a power system is first determined based on the generator relative rotor angles obtained from time domain simulation outputs. Simulations were carried out on the IEEE 9-bus test system considering three phase faults on the system. The data … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,027 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Creative, Educational Drama Activities on Developing Oral Skills in Primary School ChildrenAbdulhak Halim Ula&#351A research study was carried out to determine whether native language teaching courses that utilize creative drama activities are more efficient in developing oral communication skills in primary school students than the traditionally applied native language teaching courses. In the present research, the elements of oral communication skills of primary school students were investigated in terms of pronunciation and interpretation … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 9,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractAltered Sulfur Amino Acid Metabolism In Immune Cells of Children Diagnosed With AutismJung H. Suh, William J. Walsh, Woody R. McGinnis et al.Autism Spectrum Disorder (ASD) is a behaviorally defined neurodevelopmental disorder whose etiology is poorly understood. Recent studies have shown that autistic children may be experiencing increased inflammation and oxidative stress. Altered immune regulation may be one contributing factor to inflammation and oxidative stress in autistic children. Sulfur amino acid (SAA) metabolism plays a critical role in regulating blood leukocyte functions … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 10,789 accessesView PDFCite
