Research ArticleOpen accessIn the abstractGeochemistry of Siloam and Tshipise Geothermal Springs, Limpopo Province, South AfricaOlatunde Samod Durowoju, John Ogony Odiyo, Georges-Ivo Ekosse EkosseGeothermal springs are natural geological phenomena that occur throughout the world, and South Africa (SA) is endowed with several springs of this nature. Most of the geothermal springs in SA (31%) are found in Limpopo Province. Assessment of geochemistry of Siloam and Tshipise geothermal springs were undertaken during 2014 winter (May – July) and summer (October – December) seasons. Water … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Mar 2018 · 8,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Detection of Nitrite and Nitrate in Celeries and CarrotsDongwu Liu, Jinye Niu, Ling Kong, Zhiwei ChenIn this study, the anions nitrite ion (NO2-) and nitrate ion (NO3-) in celeries and carrots were detected with the technique of ion chromatography. A Dionex ICS-2000 ion chromatograph was used to detect the content of NO2- and NO3- in celeries and carrots. NO2- and NO3- were separated on a DIONEX Ionpac AS19 A-4 mm ion-exchange column and an Iopac … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 14 May 2016 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Feedlot Nutrients Runoff by Electrocoagulation ProcessArjun Thapa, Shafiqur Rahman, Md. Saidul BorhanNutrient runoff from Concentrated Animal Feeding Operations (CAFOs) may cause ground and surface water pollution. Scientists and researchers are continually searching for appropriate technologies to mitigate feedlot nutrient runoff pollution. In this study, suitability of electrocoagulation treatment process was examined under laboratory conditions to mitigate nutrient pollutants from the feedlot runoff. Feedlot runoff was treated with three different type of … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 9 Nov 2015 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical Studies of Carboxy Methycellulose-Chitosan Blend Biopolymer Doped Dodecyltrimethyl Ammonium Bromide Solid ElectrolytesNur Yasmin Abu Bakar, Nur Hafiza Mr. Muhamaruesa, Nur Ain Bashirah Aniskari, Mohd Ikmar Nizam Mohamad IsaIn this study, a polymer-blend system consist of Carboxy Methylcellulose (CMC)-Chitosan (CS) as blend biopolymer host and doped with various composition of Dodecyltrimethyl Ammonium Bromide (DTAB) were successfully prepared via solution casting techniques. The new system has been analyzed through Electrical Impedance Spectroscopy (EIS) from temperature 303 K until 393 K to determine the conductivity of biopolymer electrolytes in the … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 5 Mar 2015 · 7,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractELECTROLYSIS OF SWINE MANURE EFFLUENTS USING THREE DIFFERENT ELECTRODES Fe-Fe, Al-Al AND Fe-AlS. Rahman, M. S. BorhanSwine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 9 Oct 2014 · 9,177 accessesView PDFCite
