A number of analyses, meta-analyses, and assessments, including those performed by the Intergovernmental Panel on Climate Change, the National Oceanic and Atmospheric Administration, the National Renewable Energy Laboratory, and the International Energy Agency, have concluded that deployment of a diverse portfolio of clean energy technologies makes a transition to a low-carbon-emission energy s...
Abstract The purpose of this work is to design an energy scavenging system. system scavenges ambient from indoor Wi-Fi routers. It makes use low cost, environment-friendly and widely available corrugated cardboard substrate. circuit realized on metallic layers made low-cost copper tape. A Villard rectifier used convert the RF into dc. measured scavenged power at density 10 μ W cm −2 −15.76 dBm ...
In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
in this paper, the optimal location and characteristics of tadas dampers in moment resisting steel structures, considering the application of minimum number of tadas dampers in a building as an objective function and the restriction for destruction of main members is studied. genetic algorithm in first generation randomly produces different chromosomes representing unique tadas dampers distribu...
Objective(s): There are controversial results regarding the effect of the interaction of CETP polymorphisms with dietary fats on the lipid profiles. The aim of this study was to examine the effect of CETP polymorphisms (rs5882 and rs3764261) and macronutrient intakes interaction in relation to metabolic syndrome (MetS) or its components.Materials and Methods: In this nested case-control study, ...
Consumers’ increased awareness of social and environmental issues encourages airlines to implement corporate responsibility (CSR); however, the effectiveness CSR according airline type remains unclear. This study examines roles service quality in enhancing passengers’ brand love industry explores moderating role on CSR–brand quality–brand relationships. To test theoretical model, we conducted a...
