Baseline characterization of concentrations and isotopic values of dissolved natural gases is needed to identify contamination caused by the leakage of fugitive gases from oil and gas activities. Methods to collect and analyze baseline concentration-depth profiles of dissolved CH4 and C2 H6 and δ13 C-CH4 in shales and Quaternary clayey tills were assessed at two sites in the Williston Basin, Ca...

OBJECTIVE To compare the benefits of a thermal cure and non-thermal rehabilitation in treatment of knee osteoarthritis (KOA). METHODS Randomized therapeutic trial including patients with knee osteoarthritis (American College of Rheumatology criteria). Patients were randomly divided into two groups. Spa treatment consisted of underwater shower, massage-jet showers, hydromassage, pool rehabilit...

in this study, the adsorption of hexavalent chromium and zinc ions from the solution is investigated by raw red mud and mechanical-chemical activated red mud along with the possibility of selective reclamation of these ions from the solution. the mechanical-chemical activation of red mud was done by employing high-energy milling and subsequent acid treatment with hno3. raw red mud (rrm) and mec...

Another look at the origin of the fluid mud layer in Lake Apopka, Florida Schelske (2006) questions our conclusion (Bachmann et al. 2005) that a major portion of the fluid mud layer in Lake Apopka is derived from the liquefaction of underlying consolidated sediments. In particular, he questions our interpretation of mean depth measurements that did not decrease in the period 1968 to 1996 when t...

Drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. There are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. The present work aims are study on the modified drilling mud properties by using the ...
