Hashemi PourProblem statement: The aim was to find out whether undergraduate students in Iranian dental schools were taught about and used clinically Mineral Trioxide Aggregate (MTA). Approach: Iranian senior dentistry students (487) were evaluated in this cross-sectional study. A questioner was prepared which contained personal questions in addition to theoretical and practical information about the use of MTA in senior dentistry … …Current Research in Dentistry, Vol. 1, Issue 2 · 16 Jul 2011 · 7,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Generation and Recycling: Comparison of Conventional and Industrialized Building SystemsRawshan Ara Begum, Siti Khadijah Satari, Joy Jacqueline PereiraProblem statement: In the Malaysian construction industry, there is a pressing issue of minimizing construction waste, which cause significant impacts on the environment. With the increasing demand for major infrastructure projects, commercial buildings and housing development programmers, a large amount of construction waste is being produced. Adoption of prefabrication and industrialized building systems is now a priority in the industry … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 9,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Enhancing Urea-Humic Acid Mixture with Refined Acid Sulphate SoilMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Acid Sulphate Soil (ASS) is a problem soil partly because of its high acidity. This low pH could be exploited to reduce ammonia loss from urea by reducing soil microsite pH. The use Humic Acid (HA) to control ammonia loss from urea has been reported but the cost of this material is high. This laboratory study compared the … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,282 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost-Effective Fabrication of Self-Made 1×12 Polymer Optical Fiber-Based Optical Splitters for Automotive ApplicationMohammad Syuhaimi Ab-Rahman, Hadi Guna, Mohd Hazwan Harun et al.Problem statement: Multimode fiber cables can conduct many light rays and can operate free of disruption and with a greater bandwidth than a wireless connection. However, due to a slight variation in the speed of the light rays through the multimode fiber, a signal transmitted by all of these rays becomes spread out. Consequently, the signals become broader and therefore … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractKnowledge of Chemical Hazards and Prevalence of Darkroom Diseases among Darkroom Technicians and Assistants in Southeast, NigeriaMark C. Okeji, Felicitas U. Idigo, AngelMary C. Anakwue, Uloma NwoguDarkroom technicians and assistants are exposed daily to x-ray processing chemicals. These chemicals contain known irritants which can cause some disease symptoms to its handlers. The aim of this study was to assess the knowledge of chemical hazards and prevalence of darkroom diseases among darkroom technicians and assistants in Southeast, Nigeria. The study adopted cross-sectional survey. A total of 105 … …Current Research in Medicine, Vol. 6, Issue 2 · 24 Nov 2015 · 8,128 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE ABSENCE OF ANTIMATTER FROM THE UNIVERSE, DARK MATTER, THE FINE STRUCTURE PARAMETER, THE FLUCTUATIONS OF THE COSMIC MICROWAVE BACKGROUND RADIATION AND THE TEMPERATURE DIFFERENCE BETWEEN THE NORTHERN AND SOUTHERN HEMISPHERE OF THE UNIVERSEEmmanuil ManousosThe theory of selfvariations correlates five cosmological observations considered to be unrelated by the physical theories of the previous century. The absence of antimatter from the Universe, the Dark Matter, the slight variation of the fine structure parameter, the temperature fluctuations of the cosmic microwave background radiation and the temperature difference between the northern and southern hemisphere of the Universe … …Physics International, Vol. 5, Issue 1 · 28 Nov 2014 · 8,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,939 accessesView PDFCite
