Trial of liquidation cementation of boreholes at Carpathians oil and gas deposits

open access: yesBudownictwo i Architektura, 2015
Complex geological structure as well as long-term intensive operation of oil and gas deposits in Borislav-Pokutska zone of Carpathians leads to changes in thermo-dynamical parameters of pools, rock deformation and, as a result, to crippling of the ...

Post-cementation sensitivity of bridges cemented with different adhesive resin cements

open access: yesJournal of Clinical and Experimental Dentistry
Post-cementation sensitivity remains a common clinical concern in fixed partial dentures (FPDs), with variations in adhesive resin cement formulations influencing patient discomfort and long-term success. This study aimed to compare post-cementation sensitivity in FPDs cemented with three different resin cements: self-adhesive resin cements, resin ...

Bone cement [PDF]

open access: yesJournal of Clinical Orthopaedics and Trauma, 2013
The knowledge about the bone cement is of paramount importance to all Orthopaedic surgeons. Although the bone cement had been the gold standard in the field of joint replacement surgery, its use has somewhat decreased because of the advent of press-fit implants which encourages bone in growth.
