Research ArticleOpen accessIn the abstractOccupational Exposure of Pesticides on Activities of Alanine aminotransferase and γ-Glutamyltranspeptidase in Blood among Vegetables FarmersShamsul Bahari Shamsudin, T. Hang YapProblem statement: Most vegetable farmers are using agricultural chemicals on their farms. Many of these chemicals are used to control pests and are known as pesticides. Pesticides can be considered according to their chemical basis. Most of the more toxic pesticides fall into chemical groups of organophosphates, carbamates and bipyridyls. Approach: The general objective to study the level of liver … …Current Research in Medicine, Vol. 2, Issue 2 · 4 Oct 2011 · 7,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractTermite Damage to Buildings: Nature of Attacks and Preventive Construction MethodsAbdel Ghaly, Skai EdwardsProblem statement: Termites are an essential member of the soil ecosystem and are found throughout the world. In their natural environment, they improve soil pH, organic carbon content, water content and porosity by cycling dead organics. However, they can negatively impact human welfare by causing damage to unprotected timber structures, underground cables, earthen dams, irrigation ditches and farming equipment. Globally, … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 26,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Extractants on the Yields and Selected Chemical Characteristics of Humic Acids Isolated from Tropical Saprists PeatLee Jia Huey, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Humic acids are beneficial to soil aggregation, binding of heavy metal, plant growth and many more. However, the isolation of Humic Acids (HA) from its origin is not only time-consuming, but the isolation is also affected by factors such as temperature and the types of extractants and their concentrations. Different concentrations of extractant are said to alter the … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffective Factors in Achieving Sustainable AgricultureTahereh Sharghi, Hassan Sedighi, Abdolreza Roknoddin EftekhariProblem statement: The indiscriminate use of chemical inputs led to severe degradation of resources in Iran. Therefore, considering the increasing population and growing demand of agricultural products, it seems necessary to achieve a sustainable agriculture. In this study, sustainable agriculture refers to a kind of agriculture which is ecologically appropriate, economically justifiable, and socially desirable. Approach: There were two objectives … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Optimization of Fermentation Conditions for Cellulase Production from Palm Oil Mill EffluentJamal I. Daoud, Md. Zahangir AlamProblem statement: Palm oil mill effluent discharged by the oil palm industries is considered as the mixed of high polluted effluent which is abundant (about 20 million tonnes year-1) and its effect contributes to the serious environmental problems through the pollution of water bodies. Approach: The aim of this study was to identify the potential of low cost substrate such … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactor Analysis, Target Factor Testing and Model Designing of Aromatic Solvent Effect of the Formyl Proton Nuclear Magnetic Resonance Chemical Shift in Para substituted BenzaldehydesGhazwan F. FadhilProblem statement: The variations of formyl proton Chemical Shifts (CS) of p-substituted benzaldehydes in aromatic solvents were investigated. The validity of several physical solvent and empirical solvent scales was examined. Also, to predict dipolarity-polarizability (π*) solvent scale for some aromatic solvents. Model designing was also achieved to rationalize the aromatic solvent effect on the formyl proton CS. Approach: The previously … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetabolic Fingerprinting of Three Malaysian Ginger (Zingiber officinale Roscoe) Using Gas Chromatography-Mass SpectromertryH.J. Mahdi, R. Andayani, IshakProblem statement: There is a chemical variation among different ginger cultivars detected by previous studies including the volatile and non-volatile oleo-resins. In this study we try to determine whether these variations are related to a genetic factor rather than environmental or intrinsic factors. Approach: A comprehensive metabolic fingerprinting from the leaves of three micro-propagated ginger cultivars Bukit Tinggi, Tanjung Sepat … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Effect of Three Nitrate Fertilizers on Nitrate Leaching under the Root Zone in Clay Loam SoilThamer Ahmed Mohammed, M. Nooshin, Megat Johari Megat Mohd. Noor, A. LiaghatProblem statements: Nitrogen fertilizer is recognized as an important factor in crop’s yield level, however more application of N fertilizers in the soil have some adverse effects on environment and especially on groundwater contamination. Perception and recognition the factors influencing nitrate transport through soil profile is helpful for fertilizer management to minimize adverse impacts on environment and nitrate leaching below … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractLumbricus rubellus Protein Fraction DLBS1033N Increases Nerve Growth Factor Expression via Tyrosine Kinase ActivationAgung Heru Karsono, Raymond Rubianto Tjandrawinata, Maggy Thenawidjaja SuhartonoNerve injury occurred due to mechanical, thermal, chemical, or ischemic factors. Nerve regeneration is needed for recovery. Schwann cell proliferation and differentiation are important factors in the nerve regeneration process. Schwann cells release neurotrophins in the nerve regeneration process. In this study, Lumbricus rubellus protein fraction DLBS1033N was used as therapeutic protein candidate for nerve regeneration treatments. DLBS1033N treatments promoted … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 7 Feb 2018 · 9,407 accessesView PDFCite
