Health impact assessment of air pollution using dynamic exposure profile: Implications for exposure and health impact estimates

In both ambient air pollution epidemiology and health impact assessment an accurate assessment of the population exposure is crucial. Although considerable advances have been made in assessing human exposure outdoors, the assessments often do not consider the impact of individual travel behavior on such exposures.Population-based exposures to NO2 and O3 using only home addresses were compared with models that integrate all time-activity patterns

Sharp Corporation is looking to sell solar project developer Recurrent Energy for approximately $321 million as part of a reorganization, according to reports from the Kyodo News agency. Recurrent has a solar project portfolio of 500 megawatts and a pipeline of 2.5 gigawatts, according to the firm.

When Recurrent Energy was purchased by Osaka-based Sharp in 2010, it was happy news for the solar industry and, to some extent, the venture capitalists investing in the solar space. Sharp paid $305 million for a 100 percent stake in Recurrent Energy, a solar project developer. Investors in Recurrent included Mohr Davidow Ventures and Hudson Clean Energy Partners. It was MDV

As drinking water sources become scarce, the dependence on groundwater increases. But groundwater is brackish in many places and the technologies to make salty water potable are high on energy consumption, inputs and maintenance costs. Scientists have now found a cost- effective device to desalinate water. They have taken their cue from one of the guiding principles of water purification
