Research ArticleOpen accessIn the abstractDevelopment and Testing of an Ammonia Removal Unit from the Exhaust Gas of a Manure Drying SystemA. E. Ghaly, K. N. MacDonaldThe storage and handling of animal wastes is one of the main sources of ammonia gas emissions. Ammonia gas has a distinct, unpleasant odor and can become detrimental to the health of humans and animals at high concentrations. Ammonia emissions are of particular concern in manure drying systems, where large losses of nitrogen, in the form of ammonia can cause … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 16 Feb 2013 · 7,415 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Low Temperature on the Fabrication of Microring Resonator by Wet EtchingHazura Haroon, Sahbudin Shaari, P. Susthitha Menon et al.Research related to semiconductor devices often relies on wafer fabrication. The fabrication of Silicon (Si) based devices by anisotropic wet etching can be affected by many etching parameters such as etching temperature, crystal orientation and percent of composition. Most of the anisotropic wet etchings by KOH solution done before were conducted at temperature over 70°C. We found that the temperatures … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 7,126 accessesView PDFCite
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 abstractDrying of Poultry Manure for Use as Animal FeedA. 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 have become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Jul 2012 · 12,085 accessesView PDFCite

Research ArticleOpen accessIn the abstractSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Parameters Relationship to Backcutting Phenomena During High Speed End Milling of AISI H13Erry Yulian T. Adesta, Afifah Mohd Ali, Delvis Agusman et al.Problem statement: In die and mold industries, surface roughness of the dies and molds produced will determine the end product quality. Therefore, the desired finish surface was specified and the appropriate processes were selected to reach the required quality. Among many contributors to surface quality problem, backcutting is one of the factors influencing the surface roughness. Approach: The aim for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociated Health Effects among Residences Near Jeleeb Al-Shuyoukh LandfillK. Schrapp, N. Al-MutairiProblem statement: There is growing concern about landfill adverse health effects from exposure to landfill emissions. Approach: Airborne dust samples from houses near Jeleeb Al-Shuyoukh landfill and control residences were analyzed for molds and bacteria and Volatile Organic Compounds (VOCs) each month for one year. Results: The number of mold species was greater in the residences close to Jeleeb Al-Shuyoukh … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 16 Jun 2010 · 7,619 accessesView PDFCite

Approach: Data were collected from documents and field study in … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Botrytis allii Munn the Causal Agent of Neck Rot, the Post Harvest Disease in Onion, by use of a New Iranian Isolate of StreptomycesM. Jorjandi, G.H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: Soil actinomycetes particularly Streptomyces spp. have showed antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. Onion neck rot or gray mold caused by Botrytis allii have imposed economic post harvest damages to onion bulbs and decreased its storage durability and market value. Approach: To investigate for … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,935 accessesView PDFCite
