Review ArticleOpen accessAll words, across the recordNanoplastics in the Environment and the Effects on the ZebrafishJimmy De León, María del C. Cotto, Francisco MárquezPlastic is one of the most used materials in the world, adopted in almost all activities of human life, but due to the high persistence and durability in the environment, it is causing pollution problems. Through different processes, small particles of polymers are emerging and the effects on the health are still unknown. The Danio rerio (zebrafish) is a model … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 8 Oct 2019 · 7,695 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSpiral Wound Reverse Osmosis Membranes for the Recovery of Phenol Compounds-Experimental and Parameter Estimation StudiesG. Srinivasan, S. Sundaramoorthy, D.V.R. MurthyProblem statement: Reverse osmosis is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. The removal of an organic compound, namely phenol, using a polyamide membrane was investigated in this study. Waste water containing phenol present a serious environmental problem and increasing attention is being given … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,304 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnvironmental Pollution by Heavy Metals in the Gold Mining Region of East CameroonDallou Guy Blanchard, Ngoa Engola Louis, Abdourahimi et al.The main objective of this study is to assess the level of heavy metals pollution in soil samples collected around gold mines located in Betaré Oya (BO) and Batouri (BA) in Eastern Cameroon. Elemental analysis of soil samples was carried out using Quant´X EDXRF spectrometer. Its sensitivity and accuracy were increased by using the Fundamental Parameter approach for quantification of … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 7 Nov 2018 · 9,777 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEcological Studies of Epiphytic Microalgae and Epiphytic Zooplankton on Seaweeds of the Eastern Harbor, Alexandria, EgyptN. G. Shams El-Din, N. A. Shaltout, M. Z. Nassar, A. SolimanA qualitative and quantitative study on the epiphytic microalgae and epiphytic zooplankton were conducted in order to follow up their community structures on seaweeds in relation to some physico-chemical variables in the coastal waters of the Eastern Harbor of Alexandria. Water and macroalgal samples were collected seasonally during two years successively: Winter, summer, autumn (2012) and spring (2013). The collected … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 9 Dec 2015 · 7,587 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIndoor Environmental Comfort in Malaysian Urban HousingYaik-Wah LimIn Malaysia, terraced houses have been rapidly constructed since 50 years ago and account for 44% of the existing urban housings. However, these houses have very limited use of natural ventilation and daylighting due to openings with small window-to-floor ratio. The deep plan design causes gloomy indoor spaces, low air change rate and poor indoor air quality. Studies showed that … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 22 Nov 2013 · 7,467 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUsing Worldview-2 Satellite Imagery to Support Geoscience Studies on Phlegraean AreaPasquale Maglione, Claudio Parente, Andrea VallarioWorldView-2 satellite imagery includes half-meter panchromatic resolution and 2 m multispectral resolution. Because of the reduced dimensions of pixels and articulated spectral acquisition these images supply detailed information that can be used for geoscience applications, above all to investigate areas, identify land cover, bound vegetated zones, outline transformations (change detection). The aim of this study is to remark possibilities to … …Current Research in Geoscience, Vol. 3, Issue 1 · 4 Sep 2013 · 7,939 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSeroprevalence of Toxoplasma gondii Among Schizophrenics at Hospital KajangLovetta Yatta Juanah, Juliana Jalaludin, Malina Osman, Zubaidah Jamil OsmanStudies have found a high seroprevalence of T. gondii in schizophrenia patients than controls. This case-control study was done to determine the serprevalence of Toxoplasma gondii and to identify its risk factors among schizophrenia patients at Hospital Kajang. Eighty-eight (88) schizophrenia patients and 88 non-psychiatric controls were examined for the presence of anti-Toxoplasma IgG and IgM antibodies by Enzyme Linked … …American Journal of Infectious Diseases, Vol. 9, Issue 1 · 20 Feb 2013 · 8,570 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStudies On Bioemulsifier Production by Bacillus licheniformis PTCC 1595Gholamreza D. Noudeh, Mohammad H. Moshafi, Payam Khazaeli, Farideh AkefSurfactants are amphipathic molecules which reduce surface and interfacial tensions and widely used in pharmaceutical, cosmetic, food and petroleum industries. Biosurfactants are the structurally diverse group of surface-active molecules synthesized by microorganisms. There are several advantages for biosurfactants in contrast with chemical surfactants, such as lower toxicity; higher biodegradability; better environmental compatibility; higher foaming; high selectivity and specific activity at … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,282 accessesView PDFCite
