Research ArticleOpen accessIn the abstractPhysico-Chemical Characteristics of Date Seed Oil Grown in SudanRehab Salih Mahmoud Abdalla, Alsheikh AlGilani Albasheer, Abdel Rahim Mohamed ELHussein, ELrasheed Ahmed GadkariemProblem statement: Studies were conducted on the physical-chemical properties of Sudanese date seed oil extracted from two date palm cultivars (Phoenix dactylifera L.) ALBarakawi and Alqundeila. The extracted oil from ALBarakawi seeds weighed 6.833% w/w oil, Alqundeila oil extracted weighed 5.064% w/w. Approach: The physical properties of ALBarakawi oil were: viscosity: 17cp, refractive Index: 1.444, density: 0.9116 g cm-3 color: … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 5 May 2012 · 9,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat-Modeling of Microwave Assisted Epoxidation of Palm Acid OilN. Saifuddin, L. Wei Zhan, K. Xin NingProblem statement: While microwave chemistry could well be the most convenient, rapid and energy-saving way to initiate a chemical reaction, the issues of thermal versus microwave specific effect remain unaddressed. Approach: A three-dimensional Finite Element Model (FEM) was developed to predict temperature profile during the enzymatic epoxidation of palm acid oil using microwave heating. Three-dimensional partial differential equations are formulated … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,676 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 abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical and Biological Warfare: Should Rapid Detection Techniques Be Researched To Dissuade Usage? A ReviewMark R. Hurst, Ebtisam WilkinsChemistry, microbiology and genetic engineering have opened new doorways for the human race to propel itself to a better future. However, there is a darker side to Bioengineering. One element of this is the manufacture and proliferation of biological and chemical weapons. It is clearly in the interest of humankind to prevent the future use of such weapons of mass … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Grain Size on Selected Physico-Chemical Properties of ClayOsumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Mixture of the right proportion of expanding and non-expanding clays to improve plasticity (moldability) of clays used in the pot industry of Malaysia is yet to be well investigated. In addition, little is known about the choice of the right clay size to eliminate or reduce the content of undesirable compounds such as Fe2O3, Al2O3 to improve the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractBio-oils from Pyrolysis of Oil Palm Empty Fruit BunchesMohamad Azri Sukiran, Chow Mee Chin, Nor Kartini Abu BakarProblem Statement: The palm oil industry generates an abundance of oil palm biomass such as the mesocarp fibre, shell, empty fruit bunch (EFB), frond, trunk and palm oil mill effluent (POME). For 80 million tonnes of fresh fruit bunch (FFB) processed last year, the amount of oil palm biomass was more than 25 million tones. The objectives of this study … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 11,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Cost Long Distance Detector for Explosives and Chemical Analysis by IEC ApplicationGeorge H. Miley, Heinrich Hora, Frederick Osman et al.A radiation source for detecting specific chemicals at several meter distances even behind walls, car doors or other barriers is the application of Million electron Volts (MeV) neutrons from nuclear fusion reactions at such low intensities to avoid any danger for human bodies. The chemical analysis consists in the neutron activation of nuclei emitting then gamma radiation of lines very … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Challenge of the Hospitals and Health Care Systems in Preparation for Biological and Chemical Terrorism AttackEldo Ermenegildo Frezza MDIn the present study a few aspects of planning for terrorism events that expose large numbers of people to contamination are discussed. Many issues were considered as an absolute requirement for implementation of NBC response: 1) policy, 2) plan and 3) emergency department response to surge capacity. Key elements of the healthcare facility response plan include prompt recognition of the … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,390 accessesView PDFCite
