EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,468 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicological Consequences of Di-N-Butyl-Phthalate (DBP) on Health of Nile Tilapia FingerlingsEhsan H. Abu Zeid, Al Shimaa A. KhalilPhthalic Acid Esters (PAEs) are mainly used in the plastics industry as adhesives and plasticizers. Di-n-Butyl Phthalate (DBP) is one of the important members in the family of PAEs was listed as environmental priority pollutants by the US Environmental Protection Agency. The objective of this study was to evaluate the toxicological consequences in Nile Tilapia Oreochromis niloticus L. fingerlings, exposed … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 24 Dec 2014 · 8,469 accessesView PDFCite

Research ArticleOpen accessIn the abstractBIODEGRADABILITY AND MECHANICAL BEHAVIOUR OF SUGAR PALM STARCH BASED BIOPOLYMERJ. Sahari, S. M. Sapuan, E. S. Zainudin, M. A. MalequeA new Sugar Palm Starch (SPS) based biopolymer was successfully developed using glycerol as plasticizer. The effect of glycerol concentration (viz., 15, 20, 30 and 40 by weight percent) to the mechanical properties of plasticized SPS biopolymer was investigated. From this investigation, it was found that the 30% glycerol concentrated biopolymer showed the highest flexural strength and impact with the … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 10 Nov 2014 · 7,710 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 · 6,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption from Aqueous Solution Onto Natural and Acid Activated BentoniteLaila Al-Khatib, Feras Fraige, Mohammad Al-Hwaiti, Omar Al-KhashmanDyes have long been used in dyeing, paper and pulp, textiles, plastics, leather, paint, cosmetics and food industries. Nowadays, more than 100,000 commercial dyes are available with a total production of 700,000 tones manufactured all over the world annually. About 10-15% of dyes are being disposed off as a waste into the environment after dyeing process. This poses certain hazards … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 28 Aug 2012 · 8,423 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectroanalytical Determination of Doripenem using a Screen-Printed ElectrodeNora H. Al-ShaalanProblem statement: The performance characteristics of Sensitive Screen-Printed (SPE) and Carbon Paste (CPE) electrodes were investigated for the Determination of Doripenem (DP) in pure, pharmaceutical preparations and biological fluids. Approach: The proposed electrodes is characterized in terms of plasticizer type, response time, pH and temperature. Results: The two electrodes showed nearly Nernstian behaviours over the concentration range of 2×10−4-5×10−2 mol/l … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 1 · 21 Feb 2012 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Symbolic Threshold: A Dynamic form of the Mind as an Expression of Radiant ThinkingFelice Corona, Francesco Perrotta, Emilia Tartaglia Polcini, Carla CozzarelliProblem statement: The definition of "symbolic species" used by Terrence W. Deacon means more complete the process of monitoring the encounter between semiotics and cognitive sciences neurosemiotics better defined. Approach: The mechanism of the symbolic threshold means that it is put in place an approach to reality no longer seen as a representative of simple association, but under a restructuring … …Neuroscience International, Vol. 1, Issue 2 · 31 Dec 2010 · 16,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractTartaric Acid Modified Rice Hull as a Sorbent for Methylene Blue RemovalSiew-Teng Ong, Pei-Sin Keng, Ai-Wen Chong et al.Problem statement: Improper dye discharge from various industries such as textile, paper, cosmetic and plastics into receiving streams can be one of the sources towards water pollution. The release of these effluents not only causes various disruptions in the ecosystems, but also poses hazard effect as most of the dyes are highly toxic, mutagenic and carcinogenic in nature. Approach: To … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation.
