AbduliProblem statement: The quality of drinking water is a crucial factor for human health. The objective of this study was the assessment of physical, chemical and bacteriological quality of the drinking water in the city of Tetova and several surrounding villages in the Republic of Macedonia for the period May 2007-2008. The sampling and analysis are conducted in accordance with … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 19 Mar 2012 · 7,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Quality Assessment of Three Zonal Regions in the Sunyani MunicipalityKwabena Antwi Kusi, Samuel Wiafe, Patrick Akaribila NsoniniThis project aimed at assessing the variation of ground water quality (physical, chemical and bacteriological parameters) in relation to the WHO standards from fifteen (15) randomly selected ground water sources in three (3) zones namely Abesim, Baakoniaba/Berlin-Top and New-Dormaa in the Sunyani Municipality. Groundwater samples were collected from five sampling points in each zone to determine the quality of the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 11 Jan 2020 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Bitumen Addition on Sabkha Soil Shear Strength Characteristics under Dry and Soaked ConditionsFahad A. Alotaibi, Humoud Melfi AldaihaniHigh salt content in sabkha soils means they are significantly affected by changes in water content. Dissolution of salts within sabkha soil mass decreases their shear strength upon inundation with water, resulting from the destruction of cementation bonds between soil particles. Therefore, successful improvement for these soils must be based on reducing the dissolution of sabkha salts to minimize their … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 13 Nov 2018 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremedial Potential of Tagetes Erecta Under Mycorrhizal Inoculation in Heavy Metal Polluted SoilI.O. Aina, F.L. Amusa, A.D. Olasupo et al.Investigation of the growth of Tagetes erecta under different levels of contamination of Copper (Cu) and Lead (Pb) in the soil and effects of mycorrhizal species (Glomus mosseae) on Cu and Pb to identify hyperaccumulator plants in tropical environment that could be used in remediation of heavy metal from contaminated soils. It was a greenhouse experiment consisted of factorial combination … …American Journal of Environmental Sciences, Vol. 15, Issue 5 · 28 Oct 2019 · 7,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Usage of Biologically Active Raw Materials in Confectionery Products TechnologyAlfiya Chernenkova, Svetlana Leonova, Tamara Nikiforova et al.Increased man-caused impact, imbalance in diets lead to diseases, premature aging and life shortening. To overcome this imbalance, there is an active search for raw materials containing the physiologically functional ingredients necessary for human health or the raw materials containing biologically active substances, vitamins, mineral substances. To enrich traditional recipes with these components and to give functional purpose to products … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 7 Mar 2019 · 8,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,957 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
