Research ArticleOpen accessIn the abstractDensity Functional Theory Based Quantitative Structure Activity Relationship Study of 2,5-Bis(1-Aziridinyl)-p-Benzoquinones with Lymphoid LeukemiaBahjat A. Saeed, Rita S. EliasProblem statement: QSAR techniques increase the probability of success and reduce time and coast in drug discovery process. The study presented QSAR investigation on 32 bioactive aziridinylbenzoquinones that have activity against lymphoid leukemia. Approach: Molecular descriptors, molecular weight, total energy, hardness, chemical potential, electrophilicity index, HOMO and LUMO energies were calculated. Initial geometry optimizations were carried out with the AM1 … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Specific Index for Measuring the Association between Periodontal Conditions and Coronary Artery DiseaseNavabi Nader, Farzaneh MehdizadehProblem statement: There is increasing evidence that periodontal disease could play a role in the Progression of coronary heart disease although there are conflicting results about this association in the literature and the difference of used periodontal scoring systems among the studies might be a reason. The purpose of this study was to evaluate a specific scoring system Periodontal Index … …Current Research in Dentistry, Vol. 1, Issue 1 · 30 Jun 2010 · 8,019 accessesView PDFCite

Approach: All of the randomly selected 337 wives who suffered from level of psychological aggression were included in this study. Straus questionnaire (CTS) is the method used to measure psychological aggression. It shows a negative relationship … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 8,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Critical Knowledge Characteristics on Degree of Inter-Firm Technology TransferA. W. Sazali, A. Haslinda, U. Jegak, C. R. RaduanProblem statement: The current issue on inter-firm technology transfer in the developing countries is centered on the efficiency and effectiveness of the transfer process by the Multinationals (MNCs). Thus, organizations in the developing countries are striving hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs) as an efficient mean … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Absorptive Capacity and Recipient Collaborativeness as Technology Recipient Characteristics on Degree of Inter-Firm Technology TransferA. W. Sazali, C. R. Raduan, U. Jegak, A. HaslindaProblem statement: As an efficient means to increase global competitiveness, technological capabilities and potential for local innovation, organizations in the developing countries are working hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs). Technology recipient characteristics, as one of the important actors/facilitators of inter-firm technology transfer, have increasingly become … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Characteristics Affecting Agricultural Extension Workers' Job Satisfaction LevelAli Asadi, Fereshteh Fadakar, Zahra Khoshnodifar et al.Problem Statement: One of the closely associated concepts with performance of an organization is job satisfaction. The purpose of this study was to investigate the relationship between personal characteristics and job satisfaction. Approach: A survey of 52 extension workers was conducted in Fars Province, southern Iran.

Research ArticleOpen accessIn the abstractEstimation of C*-Integral for Radial Cracks in Annular Discs under Constant Angular Velocity and Internal PressureA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral for single and double-edge cracks in eight annular rotating discs under constant angular velocity with and without internal pressure. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power law creeping finite element analyses have been performed and the results are … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,721 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of C*-Integral in Thin T-Sections Subjected to Projection and Remote Loading Base on Elastic Stress Concentration FactorA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral of flat T-section bar subjected to loaded projection and remote loading with a crack or crack-like flaw introduced in the fillet (i.e., high stress) region of the component. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power low creeping finite … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDFCite
