Research ArticleOpen accessIn the abstractFactor Affecting Technical Efficiency of Smallholder Rubber Farming in Northeast ThailandS. Poungchompu, S. ChantanopWith the increase of rubber production, Para rubber farmers in Northeastern Thailand have faced the limited physical and socio-economic conditions that have given rise to the improvement of technical efficiency. This study investigated the technical efficiency of Para rubber farmers. A multi-stage random sampling technique was used to collect cross sectional data on 300 farmers. The data was analyzed using … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 2 · 24 Jun 2015 · 8,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractGastroprotective Effect and Safety Assessment of Zanthoxylum Zanthoxyloides (Lam) Waterm Root Bark ExtractAlex Boye, George Asumeng Koffuor, Johnson Nyarko Boampong et al.Problem statement: Gastrointestinal ulcers account significantly for morbidity and mortality in Ghana. The study therefore investigated the gastroprotective effect of an ethanolic root bark extract of Zanthoxylum zanthxyloides and its safety for us. Approach: Gastric ulceration was induced in Sprague-Dawley rats with Indomethacin (25 mg kg-1, p.o) and was treated with 150, 250, or 500 mg kg-1 of the extract, … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 2 · 7 Aug 2012 · 8,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on the Effects of Non-Normality on the Performances of Max-DEWMA Versus SS-DEWMA ChartsTeh Sin Yin, Michael Khoo Boon ChongProblem statement: The called the Sum of Squares Double Exponentially Weighted Moving Average (SS-DEWMA) chart which is effective in detecting shifts in the mean and/or variance is compared with the Max-DEWMA (called the maximum double exponentially weighted moving average) chart. The comparison is based on the assumption that the distribution of the quality characteristic of the process is normal or … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 18 Jan 2012 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractNatural Activities of 238U, 232Th and 40K in Manganese OreH. A. Abel-GhanyProblem statement: Manganese ore is widely used in much industries. Such as ore contain natural radioactive nuclides at various concentrations. If this ore contain high concentrations of natural radioactive nuclides, workers handling them might be exposed to significant levels of radiation. Therefore it is important to determine the radioactive nuclides in this ore. Approach: The natural radionuclides (238U, 232Th and … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganochlorine Pesticide Residues in Fish Samples from Lagos Lagoon, NigeriaDavid Adeyemi, Grace Ukpo, Chimezie Anyakora, JohnPaul UnyimaduThe organochlorine pesticide (OCPs) residues were measured in three species of fish Tilapia zilli (Red belly Tilapia), Ethmalosa fimbriata (Bonga Shad) and Chrysichthys nigrodigitatus (Catfish). These fish species are a significant part of the diet of residents of Lagos Nigeria. The organochlorine pesticides analyzed include DDT(pp'1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane), DDD, DDE (pp 1,1-dichloro-2, 2-bis-(4-chlorophenyl) ethylene, HCH (gamma 1,2,3,4,5,6-hexachlorocylohexane, HCB (hexachlorobenzene),Dieldrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a octahydro-1,4,5,8 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,904 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInfluence of Drought Stress on Growth and Yield of Soybean (Glycine max L.) Genotypes in Northern GhanaIsaac Kwahene Addai, Alhassan Bawa, Maganoba CharlesStudies on induced mutation were conducted and the results indicated that stable, but desirable soybean mutant genotypes with improved agronomic traits have been produced. A series of evaluations of these mutant genotypes had earlier on been carried out and high-yielding ones such as 150, 200, 250, and 300 Gy have been identified. In the present study, the above genotypes were … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 1 Jun 2023 · 6,777 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis and Characterization of Silver/Polyvinilpirrolidone (Ag/PVP) Nanoparticles Using Gamma Irradiation TechniquesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng et al.Problem statement: In this study, attempts had been made to synthesize silver (Ag)/Poly Vinylpyrolidone (PVP) nanoparticles by ionizing radiation and at the same time overcoming some of the disadvantages previously reported by other methods such as impurities, solvent toxicity, size and distribution control and difficulty in their preparation that limits their commercialization potential. Approach: The use of this alternative method … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 9,962 accessesView PDFCite
