Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of the Ozonation Pre-treatment for Biodegradation of Aqueous Solutions of Methyltert-Butyl EtherM. Sadeghi, A. Mesdaghinia, A. Badkoubi et al.The effectiveness of ozone treatment for improving the biodegradability of recalcitrant pollutants has been proved by investigating the ozonation reaction of Methyl tert-butyl ether (MTBE) a bioresistant gasoline oxygenate. Laboratory scale experiments have been carried out, at room temperature, by bubbling, for 120 min, ozonated air (3.4 ppm min-1 ) into 3 liter of an alkaline (pH=11.5) aqueous solution (100 … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractFerulic Acid in Chinese Herbal Medicine: Regulating Autophagy for Oxidative Damage ReductionZhiyuan Lv, Qiaozhen Zhao, Shanbin Chen et al.Ferulic Acid (FA) is the primary functional component in herbal plants and traditional fermented foods. To comprehend the mechanism of action of ferulic acid, in terms of its regulation of autophagy, antioxidants and the inhibition of inflammatory pathways, the study was conducted. Oxidatively damaged human-derived hepatocytes were treated with FA and the processing concentration of FA is from 50-800 μm. … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 1 Jun 2024 · 5,486 accessesView PDFCite
Review ArticleOpen accessIn the abstractStudy of Different Types of Enzymes for Biological, Agro-Food Processing and Industrial Wastewater Treatment: An OverviewABM Sharif Hossain, Musamma M UddinThe objective of the review study was carried out from different research data to find out the innovative latest information on the waste water treatment in agro, industrial and municipal areas. From the review study, it has been noted that cellulase, peroxidage, lignage, tyrosinase, pactinase and amylase have been widely used for waste water treatment. Besides, microbial enzymes such as … …American Journal of Environmental Sciences, Vol. 17, Issue 4 · 7 Sep 2021 · 6,695 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanically Stimulated Osteoblast Cells GrowthRaffaella Aversa, Antonio Apicella, Francesco Tamburrino, Florian Ion Tiberiu PetrescuThe bones need to be built and then permanently restored to keep them functioning properly. Considering the multiple bone functions, their vitality is essential both to maintain the body and move it and to maintain its health and vigor. When most bones begin to age and have no vital function, the man also begins to age, lose water, minerals, electrolytes, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractOvicide and Larvicide Activities of the Essential Oils Extracted from Polyalthia longifolia and Clausena anisata on Sitotroga cerealellaGuy Alain Alitonou, Jean Pierre Noudogbessi, Philippe Sessou et al.This work has objectives to study the chemical composition of volatile extracts obtained from leaves of Polyalthia longifolia and Clausena anisata and to evaluate their ovicide and larvicide effects by fumigation against Sitotroga cerealella, as alternative to the pesticides of synthesis. The analyses of the extracts by GC-MS showed that the essential oil of P. longifolia contains 57 compounds representing … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 19 Jul 2017 · 7,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractReconstruction of the Depositional Setting of Tortonian Sediments in the Yowi Field, Shallow Offshore Niger Delta, Using Wireline LogsPrince Suka Momta, Minapuye Isaac OdigiWell logs and ditch-cuttings information was used to study the subsurface of the Yowi oilfields, shallow offshore, in the eastern Niger Delta sedimentary basin. The essence of the study was to determine the gross depositional environments of selected and-bodies. Electrofacies trends from gamma ray log and mineral composition of ditch-cutting samples were used to reconstruct the depositional environments in the … …Current Research in Geoscience, Vol. 6, Issue 1 · 8 Feb 2016 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of the Mechanisms of Faecal Coliform Removal from Algal and Duckweed Waste Stabilization Pond SystemsE. D.O. Ansa, E. Awuah, A. Andoh et al.The use of eco-technologies for wastewater treatment such as algal and duckweed-based pond systems is becoming popular in developing countries owing to its affordability and efficiency of pathogen removal in warm climates. The pathogen removal mechanisms of these treatment systems however is still not clearly understood and existing knowledge is also scattered in journals and books of different disciplines.

Research ArticleOpen accessIn the abstractOptical Properties of the SiO2-Na2O-CaO-Nd2O3 GlassesP. Chimalawong, J. Kaewkhao, T. Kittiauchawal et al.Problem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x) SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygens (NBOs) in glass matrix. Approach: … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,953 accessesView PDFCite
