This article engages with the work of John Plotz on our experience being caught between two worlds as we read—a world fiction that partially absorbs us, and actual world, to which remain attached. Noting lack attention pays religion he writes about semi-detachment, I respond by developing a theology semidetached reading. To think through contribution offers, turn works fiction: H. G. Wells’s “T...
To understand the Hydro-Geochemistry of urban and semi urban areas of Karachi, located in an arid region of Pakistan, various physico-chemical parameters were investigated. Only continuously pumped productive deep and shallow wells and tube wells were chosen for the analysis for their best ecological functions including drinking, domestic, industrial and agricultural activities. Multivariate st...
in this paper, the results of surface and ground water quality monitoring during drilling of three deep exploratory wells in geothermal project in north west of sabalan in meshkinshahr are analyzed. the region has been investigated by various researchers to generate electricity using geothermal energy. drilling in deep geothermal projects, a variety of materials such as cement, bentonite, barit...
Background and Purpose: Nitrate is considered as a major pollutant for groundwater resource. In recent years, the concentration of nitrate in subsurface water is increasing because du to utilization of the of using excessive amount of fertilizers and disposal of wastewater in soils. This research was carried out as descriptive study, in a rural area of Paeen Khiaban Litkooh in Amol City in 20...
Hundreds of organic chemicals are used during natural gas extraction via high-volume hydraulic fracturing (HVHF). However, it is unclear whether these chemicals, injected into deep shale horizons, reach shallow groundwater aquifers and affect local water quality, either from those deep HVHF injection sites or from the surface or shallow subsurface. Here, we report detectable levels of organic c...
Seasonal variability in groundwater pumping is common in many places, but resulting effects of seasonal pumping stress on the quality of water produced by public-supply wells are not thoroughly understood. Analysis of historical water-quality samples from public-supply wells completed in deep basin-fill aquifers in Modesto, California (134 wells) and Albuquerque, New Mexico (95 wells) indicates...
The aim of the present study was to determine the prevalence of and risk factors for venous thromboembolism (VTE) in exacerbations of chronic obstructive pulmonary disease (COPD). COPD patients hospitalised with an exacerbation were included consecutively. Symptoms, signs and clinical, haematological and epidemiological parameters on admission were noted. All patients underwent computed tomogra...
