This study analyses how political and institutional factors affected the performance of municipalities in improving social welfare in Brazil in the period from 1990 to 2000. The model adopts a stochastic production frontier, conditioned by variables related to the provision costs of services and those that can affect municipal efficiency. The results indicated that we can not reject:1) economie...

landfill leachates and leachate sediments were investigated in order to survey the discharge of uranium (u) from municipal solid waste (msw) landfills and municipal solid waste incinerator (mswi) bottom ash landfills. concentrations of u in the leachates were as high as or higher than concentrations of cd, a metal more often discussed when considering the environmental effects of landfill leach...

BACKGROUND Access to adequate quantities of water has a protective effect on human health and well-being. Despite this, public health research and interventions are frequently focused solely on water quality, and international standards for domestic water supply minimums are often overlooked or unspecified. This trend is evident in Inuit and other Arctic communities even though numerous transmi...

Lake Mead is the largest reservoir by volume in the United States and was created by the construction of the 221-meter high Hoover Dam in 1935 at Black Canyon on the lower Colorado River between Nevada and Arizona (Figure 1). Inflows of water into the lake include three rivers, Colorado, Virgin, and Muddy; as well as Las Vegas Wash, which is now perennial because of discharges from municipal wa...

Estonia has one of the most established e-voting systems in the world. Internet voting remote e-voting using the voter’s own equipment was piloted in 2005 [12] (with the first real elections using e-voting being conducted the same year) and has been in use ever since. So far, the Estonian internet voting system has been used for the whole country in three sets of local elections, two European P...

The purpose of this study was to verify the hypothesis of feminisation of the freshwater mussel Elliptio complanata exposed for one complete reproductive cycle (1 year) to a municipal effluent plume. Mussels were harvested from a reference lake and placed in specially-designed cages adapted for long-term exposure to a suspended matter-rich river environment. After exposure, mussels were collect...
