Research ArticleOpen accessIn the abstractGenomic Distance between Thymidylate Synthase and Dihydrofolate Reductase Genes Does Not Correlate With Phylogenetic Evolution in BacteriaVitor Hugo MoreauProblem statement: Dihydrofolate Reductase (DHFR) and Thymidylate Synthase (TS) exist as bifunctional enzymes coded into unique polypeptide chain in protozoans. Bifunctional DHFR-TS is associated with an increase in the enzymatic activity by channeling the substrate between the active sites. In some bacteria, DHFR and TS genes are neighbors in the genome, whereas in others, they are located millions of base … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecies Composition, Ecological Parameters and Seasonal Changes of Planktonic Ciliates Population in Bukan Dam ReservoirA. Mohsenpour Azary, F. Mohebbi, A. Eimanifar et al.Problem Statement: Since there is no evidence to identify present species in the Bukan dam reservoir, therefore, this study was conducted to provide background for fisheries purposes. Approach: The abundance and species composition of ciliates were analyzed in the Bukan Dam reservoir (west Azerbaijan, Iran) from January to December 2007. Surface water samples were collected at monthly intervals at two … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Plant Species Diversity and Physiographical Factors in Natural Broad Leaf ForestSeyed Armin HashemiProblem statement: Species diversity is one of the most important specifications of biological societies. Diversity of organisms, measurement of variety and examination of those hypotheses that are about reasons of diversity are such as affairs that have been desired by the ecologists for a long time. Approach: In this research, diversity of plant species in forest region, numbers of 60 … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,613 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Web-Based Rapid Prototyping Workflow Management Information System for Computer Repair and MaintenanceA. H. El-Mousa, Z. J. Muhsin, M. A. Al-TaeeProblem statement: Response to paper-based requests for computer and peripheral repair and maintenance has become very troublesome and slow due to the large demand and expansion at the University of Jordan. The objectives of this study were to: (i) investigate the current system processes associated with the paper-based workflow system. (ii) design and implement, using a suitable workflow management approach, … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2009 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection for an Immediate Split Structure of Tree-Based EPON Architecture-Ideal Condition AnalysisMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Networks due to its simplicity, cost effective and wide spread deployment. A failure in access networks can cause serious problems, because access network transmit aggregated high speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backbone networks, but … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimodal Integration (Image and Text) Using Ontology AlignmentAhmad Adel Abu Shareha, Mandava Rajeswari, Dhanesh RamachandramProblem statement: This study proposed multimodal integration method at the concept level to investigate information from multimodalities. The multimodal data was represented as two separate lists of concepts which were extracted from images and its related text. The concepts extracted from image analysis are often ambiguous, while the concepts extracted from text processing could be sense-ambiguous. The major problems that … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Electrical Properties by Texturing Surface on GaAs Solar Cell EfficiencyH. Abdullah, A. Lennie, M. J. Saifuddin, I. AhmadProblem statement: This project discusses on the method to resolve the optical losses problem that have been hindering the totality efficiency of the photovoltaic. Solar cell simulation could be useful for time saving and cost consumption. The Silvaco software is not widely used in designing the 2D solar cell devices because there is lots of 1D, 2D and 3D-simulation beside … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Models of Life Quality Development of Isan Marginal Communities as Affected by Installation of the Solar Home SystemPongsil Simvised, Songkoon Chantachon, Sampan RittidechProblem Statement: The electricity production system by using solar home cells is regarded as a substitute for energy which the state provides for the marginal communities because the area cannot be extended for putting up pylons with electric cables, all this for the marginal communities to have better life and being. The purposes of this thesis were to examine the … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple Pulmonary and Multivesicular Interatrial Septum Hydatid Cysts in A Native Italian PatientA. Romano, S. Giordano, F. Follis et al.Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation.
