Research ArticleOpen accessIn the keywordsPre-Feasibility Study of Hybrid Hydrogen Based Energy Systems for Coastal Residential ApplicationsMohd Zamri Ibrahim, Roziah Zailan, Marzuki Ismail, Abdul Majeed MuzathikProblem statement: The purpose of this study is to design a renewable energy hydrogen based power system to provide electricity to a coastal residential area in east coast area (Kuala Terengganu) of Malaysia. Approach: The selected case study represents a power demand of 20 kWh day-1. The autonomous system used in this study is diesel generator, wind and photovoltaic hybrid … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,828 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Hydroponic Production of Vegetables and Ornamental Pot-Plants in a Heated Greenhouse in Western Macedonia, GreeceIoannis I. Papadopoulos, Fotis Chatzitheodoridis, Christos Papadopoulos et al.In this research an evaluation-in terms of investments-of hydroponics greenhouses is carried out, as well as the possibility of the development of greenhouse crops cultivations, such as vegetables and flowers, in them is explored in Western Macedonia. The survey was realized between the years 2002-2006, in a model greenhouse, which was installed by the Public Power Corporation S.A., in soils … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,188 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimal Planning and Design of an Environmentally Friendly Hybrid Energy System for Rural Electrification in IraqAli Saleh Aziz, Sara Ahmed KhudhierCurrent power systems create environmental effects because of the using of fossil fuels, specially coal, since CO2 is released to the atmosphere. Contrary to conventional energy sources, renewable energy sources produce a clean energy which is in general free of pollution, environmentally sustainable and technologically efficient. There is an increased interest in solar energy that can generate electricity with no … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,807 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRal-Binding Protein is Required for the Maturation and Function of Dendritic CellsJozef Borvak, Mukesh Sahu, Varun Joy et al.Problem statement: Dendritic Cells (DCs) integrate responses of innate and adaptive immune system via transmitting pro-inflammatory and regulatory signals to naïve cells within draining lymph nodes. DCs have high capacity for endocytosis, both Clathrin-Dependent (CDE) and Caveolin-Dependent (CvDE). Approach: We have recently shown that ATP-hydrolysis by the multifunctional transporter protein RLIP76 is the primary determinant of the rate of CDE. … …American Journal of Immunology, Vol. 6, Issue 3 · 13 Sep 2010 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImplementation of &#34Learning from Success&#34 Model on Learning Disabilities StudentsZeev Greenberg, Ayala CohenProblem statement: Students who have difficulties with studies lack study skills, demonstrate inconsistent achievements and are generally assigned to low-level study groups. In light of this situation, they tend to develop a poor self-image and low self-esteem. Therefore it is important to identify the coping skills that lead to success, which can serve as a model for the work of … …Journal of Social Sciences, Vol. 8, Issue 3 · 28 Aug 2012 · 7,871 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Linear Model for Moving Measurements Estimation in Urban Climate StudiesClaudia Cotrim Pezzuto, Lucila Chebel Labaki, Lia Toledo Moreira Mota, Alexandre Alexandre de Assis MotaProblem statement: Several methods can be adopted to study the variations in urban climate. The mobile measurement method is one of them, involving information provided by moving measurements of air temperature, that are taken in points defined along pre-established routes and also data from fixed-point temperature recording stations. Because moving measurements are made in different times along the measurement process, … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Biogas Plants by the Application of an Internal Rate of Return and Debt Service Coverage ApproachGiuseppe Bonazzi, Mattia IottiEnergy production using renewable energy has an effect on environmental sustainability and on public expenditure. In fact, this industry is heavily assisted by public support from the European Union and the Italian State. Developing and applying a method to evaluate the return on investment for companies operating in the field of renewable energy allows them to quantify their efficient use … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 6 Apr 2015 · 7,637 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInterplay of Cytokines and Chemokines in the Pathogenesis of Systemic Lupus ErythematosusDilip Shah, Ajay Wanchu, Archana BhatnagarProblem statement: Dysbalance of T-helper-cell (Th) cytokines and chemokines was suggested to contribute to the pathogenesis of Systemic Lupus Erythematosus (SLE). Recent reports suggest the involvement of cytokines and chemokines in the pathogenesis of SLE, but their relationship with each other and particularly in the severity of disease, was not yet understood. We analyzed the interaction between cytokines and chemokines … …American Journal of Immunology, Vol. 7, Issue 3 · 21 Dec 2011 · 8,164 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstablishing an Adaptive Production-Procurement System with Markov Chain Approach Associated with 3C TheoryChun-Ta LinProblem statement: In this study, we classify the imperfect situations that the unreliability of production and the defective products might be incurred from production process into eight independently recurrent categories. Approach: With the property of recurrence of Markov chain, the limiting probability of each imperfect production category can be calculated through the transition probabilities matrix generated from these imperfect production … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,357 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDividend Maximization in the Cramer-Lundberg Model using Homotopy Analysis MethodJuma Kasozi, Fred Mayambala, Charles Wilson MaheraProblem statement: We used the Homotopy Analysis Method (HAM) to numerically compute the value function of the dividend payment in the basic insurance process. Approach: The process is a constant income stream from premiums which is subtracted a claim process of the Poisson type. Further, an allowance for payment of dividends to share holders was incorporated. Results: The case when … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,024 accessesView PDFCite
