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 norm...

Remote area electrification is a major concern for government of any developing nation. India also working it but despite continuous efforts towards remote electrification, several thousand households in are un-electrified. Several schemes have been launched by Government such areas through grid extension still many not covered under the proposed due to economic, environmental and geographical ...

In order to search for economically and environmentally optimized fusion reactors, physics properties, engineering designs and the cost of electricity (COE) are evaluated by the PEC (Physics-Engineering-Cost) system code for several magnetic confinement fusion reactors including tokamak (TR), helical (HR) and spherical tokamak (ST) reactors. The life-cycle CO2 emission amounts are also evaluate...

he transition from high- to lower-carbon production systems increasingly creates regulatory and market risks for high-emitting firms. We test what extent equity investors demand a premium compensate such thus might raise firms' cost of capital (CoE). Using data 1,897 firms spanning 50 countries over the years 2008–2016, we find distinct robust positive impact carbon intensity (carbon emissions ...

This paper reports on a hydro backed-up (HPBU) hybrid renewable energy system (HRES) for rural off-grid community in Kwara State Nigeria with an average demand load of 550.9 kWh (90.7 kW peak) per day. By using HOMER Pro software, the formulation and identification best reliable architecture attaining technical economic viability while nearby existing RE sources such as hydro, wind solar are ap...

1-year hourly wind speed data from two Burundian stations, namely Bujumbura and Muyinga, have been processed in this work to bring an efficient help for the planning installation of energy conversion systems (WECS) at those localities. Mean seasonal diurnal variations direction shear exponent derived. Two-parameter Weibull probability density functions (PDFs) fitting observed monthly annual rel...

The objective of the paper is to empirically test relation between carbon emissions, environmental disclosures, assurance sustainability reports and firms’ Cost Equity (COE) measured by an Ex-Ante proxy model. methodological approach uses Generalized Method Moments (GMM) required control endogeneity problems using a sample 929 firms that are included in Morgan Stanley Emerging Market Index. dat...

the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...
