Southeast Alaska

This study investigated the uncertainty assessing wind-power production in valleys of complex terrain using Juneau, Alaska as the testbed. The wind-speed data stem from evaluated WRF/Chem simulations for seven tourist seasons (May 15 to September 15). The percentage of wind speeds between cut-in and cutout speed differed up to about 11% among tourist seasons and up to 15% among the examined wind-turbine types. The wind -speed probability density varied the strongest among tourist seasons for wind speeds less than 3 m∙s−1 (6 m∙s−1) for wind turbines with hub heights of about 80m (30m).

The majority of lead contaminated sites in the Blacksmith Institute’s database are found in Africa, South America, South and Southeast Asia, but the problem of lead pollution plagues most developing countries worldwide. Its uses are varied; in Latin America it has often been utilized for ceramic glazing and in other countries leaded gasoline is still used. In the U.S. lead paint is the cause of a majority of lead exposures and such exposures can be expected in most countries since paint pigments using lead were commonly used worldwide up until a few decades ago.
