A USGS investigation into the transport of contaminants to public-supply wells (PSWs) in four distinctly different aquifers demonstrates how differences in the chemistry of water produced by PSWs and nearby monitoring wells can reveal where and how contamination-susceptible water enters PSWs. This knowledge can be translated into improved monitoring strategies and protection plans. Samples were...

Social rank theory suggests that mood variation is linked to the security a person feels in his/her social domain and the extent to which they are sensitive to involuntary subordination (e.g. feeling defeated and feeling inferior). Previous studies looking at rank-related and competitive behaviour have often focused on striving for dominance, whereas social rank theory has focused on striving t...

I ntensive insulin management improves glycemic control and lowers the risks of long-term microvascular complications (1). Several new insulin analogs (2) are in use to improve glycemic control in type 1 diabetes. Glargine in particular is a “basal insulin” (3) and found to be relatively peakless. Glargine is thought to provide glucose profiles similar to insulin pumps (4). Although some clinic...

BACKGROUND Subacromial impingement syndrome (SAIS) is the most common disorder of the shoulder. The evidence for the effectiveness of treatment options is inconclusive and limited. Therefore, there is a need for more evidence in this regard, particularly for long-term outcomes. HYPOTHESIS Platelet-rich plasma (PRP) would be an effective method in treating subacromial impingement. STUDY DESI...

is paper focusses on the examination of the properties of epistemic indefinites in Sinhala, with comparison to other languages, including English and Hindi. In particular, aention is placed on the determination of the felicity conditions for the two morphologicallyand pragmatically-distinct Sinhala epistemic indefinites: WH+də and WH+hari, with a concentration on the (un)availability of ident...

Analytical studies are carried out to investigate groundwater head changes in a coastal aquifer system in response to tidal fluctuations. The system consists of an unconfined aquifer, a semi-confined aquifer and a semi-permeable confining unit between them. An exact analytical solution is derived to investigate the influences of both leakage and storage of the semi-permeable layer on the tide-i...

introduction more than 90% of drinking water in cities around the world and about 40% of the agricultural water supply from groundwater resources.,thus, groundwater quality consideration issue is inevitable . one of the most important parameter which can show the quality of drinking water is nitrate concentration. nitrate enters the groundwater and surface water through the decomposition of hum...

The aquifer thermal energy storage system (ATES) owing to growing demands for sustainable energy has become a popular technology in last few decades for long term storing of excess thermal energy. The efficiency of such a system depends entirely on the capacity of the aquifer to retain heat and hence modeling the heat transfer and transient temperature distribution in the aquifer due to hot wat...
