For the first time, global ocean usable wind power is evaluated for modern offshore turbine characteristics including hub height, usable portion of the wind speed distribution and siting depth. Mean wind power increases by 30%, 69% and 73% within the tropics and northern and southern hemisphere extratropics, respectively, between hub heights of 10 m and 100 m. A turbine with a cut-out speed of ...

Colchicine has been applied to young developing anthers of Triticum aestivtim at varying stages of maturity from the last premeiotic mitoses of the archesporial and tapetal cells to the second meiotic divisions of the pollen mother cells. The developmental stage of the archesporium at which colchicine took effect was determined by cytological examination of the ploidy levels of the nuclei of th...

With the progressive exhaustion of fossil energy and the enhanced awareness of environmental protection, more attention is being paid to plug in hybrid electric vehicles (PHEV). Inappropriate siting and sizing of PHEV parking lots (PL) could have negative effects on the development of PHEV, the layout of the city traffic network, and the convenience of PHEVs’ drivers as well as lead to an incre...

The first priority in designing a strategy to control nitrogen oxides is to protect human health. Human health impacts appear to be related to peak exposures to nitrogen oxides (NOx). In addition to potentially damaging human health, nitrogen oxides are precursors to ozone (O3) formation, which can harm human health and vegetation. Finally, nitrogen oxides contribute to acid deposition, which d...

This paper examines the effects of emissions trading on firms’ capacity siting choices in the electric sector, considering three programs that are different by their point-of-regulation: source-, load and first-jurisdictional-deliverer approaches. We model each program by assuming electricity sales are through bilateral contracts, and analyze the solutions properties and economic and emissions ...

Because of limited space, the siting and construction of a new SWM facility is a big challenge in Japan. An SWM facility should be socially accepted as well as environmentally and economically sound. This study aimed to investigate people's concerns about SWM facilities and their attitudes towards such facilities. A questionnaire was designed based on literature reviews and was sent to resident...
