Rahman, Adnan JusohProblem statement: Sungai Mas, Kedah, Malaysia and OC-EO, Vietnam, was two of the Indo-Pacific beads making centre’s in Southeast Asia. The drawn monochrome glass beads or Indo-Pacific beads industry begun in Arikamedu, India since 200BC was identified by Ptolemy as Poduca Emporium, with the presence of a small colony of Roman merchants. Arikamedu was abandoned by the 3rd century and … …Journal of Social Sciences, Vol. 8, Issue 1 · 28 Oct 2011 · 8,491 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntagonistic Effects of Fertilizer on Photochemical Efficiency of Hibiscus cannabinus L. (Kenaf) Planted on Beach Ridges Interspersed with Swales SoilMohd-Hazimy Yusoff, Hazandy Abdul-Hamid, Arifin Abdu et al.Problem statement: Hibiscus cannabinus L. or Kenaf is a highly productive, warmseasonal C3 annual crop and is one of the potential candidates to substitute kenaf fiber as raw product for pulp and paper production. It survives well on less fertile soils including those of Beach Ridges Interspersed with Swales (BRIS) soil. Approach: The objective of this study was to determine … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 19 Sep 2011 · 8,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrology and Origin of Ultramfic Xenoliths from North Eastern Jordan VolcanoesHassan Al-Fugha, Mazen AL-AmairehThe distribution of major, minor and trace elements in the Cenozoic alkali basalt from north-eastern Jordan indicates a homogeneous lava flow from a mantle source. These basaltic rocks contain abundant upper mantle xenoliths (spinal lherzolite, harzburgile and olivine- websterite). Theses xenoliths contain olivine, orthopyroxne, clinoporoxene and a few amounts of spinal. Their mineral assemblages, chemistry, texture and major elements abundances … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,013 accessesView PDFCite
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 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Sintering Mechanisms for Additive Manufacturing of Conductive TracesJasmine McKenzie, Salil DesaiAdditive Manufacturing (AM) processes enable the fabrication of miniaturized and flexible devices on complex geometries. This paper explores a hybrid additive manufacturing technology that integrates micro-extrusion and PICO-jetting methods. Conductive slurries and colloidal inks were optimized for their rheological properties to aid their precise deposition. A variety of conductive materials which include carbon, silver, nano-particle silver and nickel were deposited … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 5 May 2018 · 8,669 accessesView PDFCite
InvestigationOpen accessIn the abstractEffect of Chelating Compounds of Microelements for Iodine Enrichment of Cow MilkElena Vladimirovna Bykova, Sergey Petrovich Voronin, Aleksandr Petrovich Korobov et al.This article discusses the problem of iodine deficiency and proposes a solution to this problem by enriching milk with iodine due to the use of organic compounds of microelements in diets of cows. The article presents the results of comparative study of inorganic and organic micromineral additives’ influence on the content of iodine in milk and activity of thyroid hormones … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 12 Apr 2018 · 7,813 accessesView PDFCite
Review ArticleOpen accessIn the abstractThere is Life on Mars?Relly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.If you can live on Mars, or if there was life on this planet, it's a natural question. The population of our planet has far outstripped the boundaries from which the planet begins to overcrow. Global resources are decreasing, while their consumption is rising more and more. The world's population is growing, it needs housing, food, water, air, clothes, transport, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 23 Dec 2017 · 8,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnaerobic Transformation of Biodegradable Waste; Simultaneous Production of Energy and FertilizerAmirhossein Malakahmad, Syazana Nasrudin, Noor Ezlin Ahmad Basri, Shahrom Md ZainAlmost 40% of the total waste produced in developing countries is made of biodegradable waste. Typically the waste including the biodegradable portion is transported to the so-called landfills without any segregation process, treatment and utilization in advance. Although mitigation practices such as source reduction, reuse and recycle are essential and required to be practiced in any integrated waste management plan, … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 10 Mar 2013 · 7,376 accessesView PDFCite
