Research ArticleOpen accessIn the abstractA BIOPHYSIOCHEMICAL ANALYSIS OF SETTLED LIVESTOCK AND POULTRY HOUSING DUSTSCarresse Gerald, Christi McPherson, Tha’Mes McDaniel et al.The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorized as confinement, semi-confinement or pasture-based. Characterization … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 16 Jan 2014 · 8,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Egyptian Smectitic Clay Deposits by Methylene Blue AdsorptionSalwa D. Abayazeed, Essam El-HinnawiProblem statement: The characterization of smectitic clays has been traditionally made using physical and chemical methods which are time-consuming and require costly equipment. Adsorption of methylene blue by these clays has been introduced as a quick and cheap method for the estimation of cation exchange capacity and surface area. Therefore, the aim of the present study was to test the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organotin(IV) N-Benzyl-N-Isopropyldithiocarbamate Compounds: Cytotoxic Assay on Human Hepatocarcinoma Cells (HepG2)Normah Awang, Ibrahim Baba, Nor Syaidatul Akmal Mohd Yousof, Nurul Farahana KamaludinProblem statement: Several studies on organotin(IV) dithiocarbamate compounds have been carried out but not on the synthesis and characterization together with cytotoxic assay of organotin(IV) N-benzyl-N-isopropyldithiocarbamate compounds. Approach: Three new organotin(IV) compounds of type N-benzyl-N-isopropyldithiocarbamate have been successfully synthesized by direct reaction between secondary amine with organotin(IV) chloride using in situ method. All the compounds were characterized using elemental analysis, … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Porcine Mitochondrial Transcription Factor a Gene: Molecular Characterization, Radiation Hybrid Mapping and Genetic Diversity among 12 Pig BreedsTanja Kunej, Xiao-Lin Wu, Jennifer J. Michal et al.Problem statement: Mitochondrial transcription factor A (TFAM) is a nucleus-encoded protein that is a key activator of mitochondrial transcription as well as a major participant in mitochondrial genome replication. Genomic characterization of the porcine TFAM gene is, therefore, necessary to determine its involvement in regulation of fat depots and meat quality traits in pigs. Approach: Genomic DNA sequence was determined … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization of Fusarium Oxysporum F. Sp. Cubense of BananaS. K. Leong, Z. Latiffah, S. BaharuddinProblem statement: Morphological characterization of Fusarium species which emphasize on microscopic and cultural characteristics are not sufficient to characterize Fusarium Oxysporum F. sp. Cubense (FOC) from banana as these characteristics could easily influence by environmental factors. As an alternative molecular methods were used to characterize and to assess genetic variation of FOC from different banana cultivars. Knowledge on the genetic … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 9,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Characterization of Novel Metal Accumulating Extracellular Protease Secreting Bacteria from Marine Coastal Region of Digha in West Bengal, IndiaSusmita Roy, Kaushal Mishra, Sanhita Chowdhury et al.Problem statement: The objective of the present piece of work was to explore the existing biodiversity of protease secreting microbes in a marine ecosystem, the site selected being the coastal region of West Bengal (Digha), India. Approach: The culture dependent method was used for isolation and characterization of novel microbes from the point of biotechnological application. The isolate obtained was … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractTunnel Static Behavior Assessed by a Probabilistic Approach to the Back-AnalysisClaudio Oggeri, Pierpaolo OresteProblem statement: The steps of the validation procedure of the project of a tunnel are briefly illustrated in this study, starting from the geological and structural surveys on the excavation walls and the measurement of the physical and mechanical parameters during the excavation works. Unfortunately, however, the knowledge of the rock mass, which is fundamental to the project, is usually … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 7,034 accessesView PDFCite
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
