BACKGROUND The target sample size for clinical trials often necessitates a multicenter (center of excellence, CoE) approach with associated added complexity, cost, and regulatory requirements. Alternative recruitment strategies need to be tested against this standard model. OBJECTIVES The aim of our study was to test whether a Web-based direct recruitment approach (patient-centric, PC) using ...

background: every year many organizations formulate a code of ethics (coe) but when it comes to implementing, it does not achieve the desired purposes. ineffectiveness of coes can stem from different factors and surely, one of them is bad formulation. this research was conducted to identify the barriers to effective formulation of coes in one of the main state universities of medical sciences i...

The main objective of this study is to discuss the economical and the environmental analysis of a net zero energy (NZE) tourist village in Alexandria, Egypt, by maximizing the renewable energy fraction and minimizing the greenhouse gases (GHG) emissions. The hybrid photovoltaics (PV)/wind/diesel/battery system is found to be the optimum hybrid renewable energy system (HRES) for the proposed tou...

To generate power and electricity for residential buildings, most countries in the world rely on fossil fuels. As a result of persistent increase fluctuations fuels costs which negatively affect individual's financial advancement, several were inclined to develop use cost-effective renewable energy systems such as photovoltaic (PV) systems. The objective this research is examine amount electric...

For the suggested site in Maldives, this research paper analyzes possibility of a hybrid renewable microgrid that is dispatch strategy-governed both off-grid and on-grid scenarios. The planned microgrid’s techno-environmental-economic-power-system responses have been assessed. Both power system response study techno-environmental-economic modelled were carried out using software platforms DIgSI...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

liberalization of energy price increases costs of agricultural inputs and costs of agricultural production. all these changes may affect the overall competitiveness of domestic products with similar foreign products. as a result of that, total cost of agricultural products are increased and profitability are decreased. in this paper, energy consumption for producing corn were calculated using c...

Abstract The fish-borne zoonotic bacteria may pose a risk to humans; nanobiotechnological techniques could serve as effective solutions for fighting them. direct phycosynthesis of metals’ nanoparticles (NPs), silver (AgNPs), and selenium (SeNPs) using Corallina officinalis extract (CoE) was achieved. construction nanocomposites (NCs) from phycosynthesized NPs nano-chitosan (NCht) also accomplis...
