In his reports on the regional hydrogeology of the central Great Plains, in particular southeastern Colorado and southwestern and central Kansas, Darton considered the Dakota aquifer to be a classic example of an artesian system. Computer simulations of the flow system in this study, however, suggest that the Dakota is not a regional artesian aquifer in the classic sense. Sensitivity analysis o...

A Fe, Mn-oxide catalyst was obtained by impregnation of thermally activated dolomite granules with aqueous solutions Fe(III) and Mn(II) sulfates followed heat treatment. Its physicochemical properties were studied using differential thermal analysis, X-ray diffraction, low-temperature adsorption-desorption nitrogen, scanning electron microscopy. The high efficiency Fe(II) ion oxidation in media...

The objective of this study was to examine multiple risk factors and correlated malignant neoplasms of blackfoot disease (BFD), a unique peripheral vascular disease related to continuous exposure to high-arsenic artesian well water. A total of 241 BFD cases, including 169 with spontaneous or surgical amputations of affected extremities, and 759 age-sex-residence-matched healthy community contro...

The objective of this study is to elucidate the association between high-arsenic artesian well water and cancers in endemic area of blackfoot disease, a unique peripheral vascular disease related to continuous arsenic exposure. As compared with the general population in Taiwan, both the standardized mortality ratio (SMR) and cumulative mortality rate were significantly high in blackfoot disease...

A hydraulic ram is a device for moving fluid from lower place to higher place. Hydram pumps have the same function as in general. The driving energy of pump comes pressure water entering through suction pipe into pump. By using large enough flow at low place, will with less capacity. capacity flowing depends on difference between and discharge pipe. design form model used distribute sourced art...

Anoxybacillus strain BCO1, isolated from a thermophilic (50°C) microbial mat colonizing an outflow of a Great Artesian bore well of Australia, possessed a genome of ~2.8 Mb, with a G+C content of 41.7 mol%, and encoded 3,205 genes.
