Research ArticleOpen accessIn the abstractAlnus subcordata C.A.M. Cambium Cells Dynamics Along Transport Corridors in Hyrcanian ForestsAidin Parsakhoo, Hamid Jalilvand, Mehdi SheikhiProblem statement: In this study, we considered transport corridors and sampling aspects to be the major indicators of ecological effects on Alder (Alnus subcordata) cambium cells dynamics. Approach: Thus, 240 cores were taken from forest-facing and road-facing trunk of Alder trees along Amre, Neka and Darab Kola transport corridors in hyrcanian Forests of Iran. Results showed that the roads corridor … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacterial Contamination and Resistance to Commonly Used Antimicrobials of Healthcare Workers' Mobile Phones in Teaching Hospitals, Kerman, IranGholamreza Sepehri, Nooshin Talebizadeh, Ali Mirzazadeh et al.Problem Statement: The contamination rates of Health Care Worker's (HCW) mobile phones and resistance to commonly used antimicrobials were evaluated in three teaching hospitals in Kerman, Iran. So, we examined 150 randomly selected HCWs in three teaching hospitals in Kerman, Iran, 2007. For each HCW a sterile swab moistened with sterile water was rotated over the surface of both sides … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of New Didactic Materials for Teaching Science and Biology: The Importance of the New Education PracticesDanon Clemes Cardoso, Maykon Passos Cristiano, Camila Orlandi ArentProblem statement: The creativity of teachers in the planning process of their classes for teaching science and biology may be an instigator to promote and stimulate learning. The science should be something that awakens curiosity in students to make learning pleasurable and increase their interest. The aim this research was to develop didactic materials for to help the teaching-learning process … …OnLine Journal of Biological Sciences, Vol. 9, Issue 1 · 31 Mar 2009 · 8,607 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 · 8,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelected Malaysian Wood CO2 -Laser Cutting Parameters And Cut QualityNukman Yusoff, Saiful Rizal Ismail, Azuddin Mamat, Aznijar Ahmad-YazidLaser has been used to cut most non-metallic materials very efficiently and successfully because these materials are highly absorptive by the CO2 laser wavelength of 10.6 10.6µm. Laser cutting process has been found to be reliable in loads of applications, with several advantages over other mechanical means in producing successful cut of even thermally sensitive materials such as wood. Various … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractRETRACTED: On the New Branch of Mathematical ScienceM. Sivasubramanian, S. KalimuthuThe origin of geometry dates back 30000(Thirty thousand years) B.C[3]. Euclid of Alexandria (2300 B.C.) complied the Elements which is the first scientific text book. Euclid assumed five postulates. There is no proof for the fifth postulate. Almost all the celebrated mathematicians tried their best to deduce this from the first four postulates. But unfortunately, nobody was successful. Saccheri and … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 7,893 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Three Dimensional RC Infilled Frame - RC Plane Frame Interactions With Slab for Seismic ResistanceSuyamburaja Arulselvan, K. SubramanianExperimental investigation was planned and conducted to study the influence of brick masonry infill and slab in a three-dimensional reinforced cement concrete frame. In this study, one-fifth scale 3D R.C frame representing single story, three bays with central bay brick infill at the sides and a long single bay without infill in the middle of the frame along loading direction … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,313 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Ethical Appraisal of Hormesis: Towards a Rational Discourse on the Acceptability of Risks and BenefitsOrtwin RennIt is ethically mandated that potential beneficial aspects of low exposure to potentially hazardous material are incorporated in the risk-benefit balancing procedure. The potential harm done by pollutants does not justify the invocation of a categorical principle. Minimisation of risk is not required if health benefits are also at stake. Society needs to find an informed consent on the threshold … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Thermal Contact using Nonlinear System Identification ModelsM.H. Shojaeefard, K. Goudarzi, A.R. Noorpoor, M. FazelpourOne interesting application of system identification method is to identify and control the heat transfer from the exhaust valve to the seat to keep away the valve from being damaged. In this study, two co-axial cylindrical specimens are used as exhaust valve and its seat. Using the measured temperatures at different locations of the specimens and with a semi-analytical method, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractGovernance and Democratic Procedures in the Information Society EraAthanasios I. BozinisThe use of Information and Communication Technology (ICT) in today’s democratic societies has always two sides: the well-intended, which is the expansion of the democratic participation, and the bad-intended, the one that causes concentration. This research analyzes the advantages and disadvantages of the use of e-democracy and claims that the integration of electronic democracy within a country will be based … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,359 accessesView PDFCite
