Research ArticleOpen accessIn the abstractAssessment of Soil Solution Chemicals after Tannery Effluents DisposalCélia A. Surita, Thomas Gloaguen, Célia R. Montes, Carlos T.S. DiasKnowledge about soil solution chemicals is important for assessing their mobility, availability, migration to groundwater and toxicity to plants. The objective of this study was to apply factor analysis to data obtained on soil solution chemicals during a one-year monitoring program in a controlled experiment with tannery effluents disposed on the soil surface, to extract information on their relationship and … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,772 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAttenuated Superoxide Dismutase Induction in Retinal Cells in Response to Intermittent High Versus Continuous High GlucoseMichael A. Ihnat, Ronald C. Kaltreider, Jessica E. Thorpe et al.High glucose, particularly in oscillating conditions, produces an increase in oxidative stress and has been shown to result in an increase in diabetic complications, retinopathy in particular. The hypothesis of this work was that chronic exposure to intermittent high glucose results in an attenuated induction of an antioxidant response as compared to continuous high glucose exposure in isolated retinal cells … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 7,453 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Rhizobacterial Inoculation on Growth of the Sweetpotato CultivarY. Farzana, O. RadizahSweetpotato (Ipomoea batatas L.) is the most important of local tuber crops in Malaysia. It is usually planted on marginal soils such as peat and sandy soils. Malaysian consumes a lot of sweetpotato and its production requires high fertilizer input, which can lead to increased production cost and environment problems. The use of bio-fertilizer and bioenhancer such as N2 (nitrogen) … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,869 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Dietary Inclusion of Guar Meal Supplemented by β-Mannanase on Performance of Laying Hens, Egg Quality Characteristics and Diacritical Counts of White Blood CellsMohammad Ehsani, Mehran TorkiProblem statement: Using Guar Meal (GM) in poultry diets has being limited because of having β-mannan, one of the Nonstarch Polysaccharides (NSP). In this study we try evaluating effects of enzyme supplementation of GM-included diets on productive performance of laying hens. Approach: A total number of 144 Lohmann LSL-Lite hens were divided in 24 cages (n = 6). Based on … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 8,496 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdding Medicinal Herbs Including Garlic (Allium sativum) and Thyme (Thymus vulgaris) to Diet of Laying Hens and Evaluating Productive Performance and Egg Quality CharacteristicsR. Ghasemi, M. Zarei, M. TorkiProblem statement: In trying to finding phytogenic antibiotic-substitutes this study was done and effects of adding graded levels of Medicinal Herbs (MH) including garlic (Allium sativum) and thyme (Thymus vulgaris) to laying hens’ diet on productive performance investigated. Approach: A total number of 108 Lohmann LSL-Lite hens after production peak were randomly divided in 18 cages (n = 6). Three … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 18,511 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of Treated Wastewater in Terms of Environmental StandardsSona Pazdar, Saeid Eslamian, Hossein Gholami, Kaveh Ostad-Ali-AskariThe desired use of refined wastewater has not yet found its proper place in many countries, therefore, achieving a relative equilibrium in the field of urban wastewater evacuation and re-utilizing it is a fundamental principle. And this great matter is not possible except by developing a comprehensive refinery waste management system. The set of measures that have been taken so … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 27 Sep 2019 · 7,908 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSpatial 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 PDF Cite
