Research ArticleOpen accessIn the keywordsModeling Growth of Microalgae Dunaliella Salina under Different Nutritional ConditionsSergio Santos Jesus, Rubens Maciel FilhoProblem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,014 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Cement Kiln Dust on the Soil Electrical ResistivityHamid Ranjkesh Adarmanabadi, Arezou Rasti, Mehrdad RazaviElectrical resistivity is a non-destructive, cost-effective and sensitive method to evaluate soil's physical and chemical properties. Electrical resistivity has been used widely in surface and subsurface exploration. The electrical resistivity is directly related to the subsurface geotechnical and geothermal properties like porosity, temperature, salinity and water content. Recently uses of waste material as an additive to improve the soil engineering … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 14 Jan 2021 · 7,272 accessesView PDF Cite

Research ArticleOpen accessIn the abstractScale Formation Due to Water Injection in Malaysian Sandstone CoresAmer Badr Bin Merdhah, Abu Azam Mohd YassinProblem statement: Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Approach: This study was conducted to investigate the permeability reduction caused by deposition of calcium, strontium and barium sulphates in sandstone cores from mixing of injected Malaysian sea waters (Angsi and Barton) and formation water … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPresence and Origin of Fluoride in the Complex Terminal Water of Ouargla Basin (Northern Sahara of Algeria)Imed Eddine Nezli, Samia Achour, Mohamed Djidel, Saïd AttalahProblem statement: The underground waters in the oriental regions of the Algerian Sahara, present real chemical quality problems. Their content in fluorides always exceeds the limit of the recommended levels. That is 0.8 mg L-1, according to the maximum temperature in the region. Combined to a high salinity, it affects the health of the population living around the region. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,671 accessesView PDF Cite
