Research ArticleOpen accessIn the abstractAn Effective Passive Solar Dryer for Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldAnimal and poultry manures have been recognized for centuries as organic fertilizers providing essential nutrients to crops and improving soil structure due to their large input of organic matter. Increasing demand for poultry and egg products has led to intensification of the poultry rearing process, resulting in large amounts of poultry manure. Drying can be used to reduce the environmental … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Aug 2012 · 10,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Properties of Wheat Straw Varieties Cultivated Under Different Climatic and Soil Conditions in Three ContinentsYaning Zhang, A. E. Ghaly, Bingxi LiOver 500 million tonnes of wheat straw are produced annually worldwide, the majority of which are burnt in the field causing significant environmental and health problems as well as serious traffic accidents in addition to loss of a valuable resource. Wheat straw is abundantly available and renewable and can be used as an energy source in gasification and combustion systems. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 26 Jun 2012 · 21,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 9,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferences in Soil Physical and Chemical Properties of Rehabilitated and Secondary ForestsM. H. Akbar, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The soil properties of tropical rain forest in Southeast Asia have been characterized by several researchers; however empirical data on soil characteristics under rehabilitation program are still limited or even lacking. This research is important to determine the soil physical and chemical properties of a rehabilitated degraded forest land 19 years after planting with various indigenous species in … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 12,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Converting Secondary Tropical Peat Swamp Forest into Oil Palm Plantation on Selected Peat Soil Physical PropertiesMohd Suffian Firdaus, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: The conversion of forest land into oil palm plantation is considered to be one of the causes of soil degradation and loss of tropical land forest in Southeast Asia. The objective of this study was to compare selected peat soil physical properties of secondary tropical peat swamp forest and oil palm plantation to determine the effect of forest … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil-moisture Retention Characteristics of Earth Materials in the Weathering Profile over a Porphyritic Biotite GraniteJohn Kuna RajProblem statement: Three broad morphological zones and several sub-zones were differentiated within the weathering profile based on variations in earth materials and the degree of preservation of original bedrock minerals, textures and structures. Approach: The topmost Zone I (Grade 6) is some 12 m thick and comprises completely weathered bedrock materials (mainly a stiff, clayey sand) with indistinct relict bedrock … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 9,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Novel Disk-type Furrow Opener Used in No-Tillage System on Micro Environment of SeedE. Seidi, S.H. Abdollahpour, A. Javadi, M. MoghaddamProblem Statement: Offset Double-Disk Opener (DDO) is a popular furrow opener in conservation tillage. It has some limitations such as negative suction to penetrate in the soil, hair pinning and mixing seed and fertilizer in the slot. Because of importance of separation of seed and fertilizer in the slot, by adding two horizontal mini disks to DDO a modified opener … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,155 accessesView PDFCite
