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.

Numerical Simulation on the Safety and Quality of Cementing by Using Pad Fluid in Horizontal Wells
The failure of wellbore sealing will cause leakage of greenhouse gases, such as carbon dioxide and methane, which will harm oil and gas recovery and environmental safety. Cementing is an important part of wellbore sealing.

Experimental Methods for Investigation of Drilling Fluid Displacement in Irregular Annuli
Experimental methods are still indispensable for fluid mechanics research, despite advancements in the modelling and computer simulation field. Experimental data are vital for validating simulations of complex flow systems. However, measuring the flow in

Cement-within-cement revision hip arthroplasty [PDF]
We reviewed 19 revision hip arthroplasties in which the new femoral component had been recemented into the old, intact cement mantle. The mean time from the first operation to revision was 64 months and the average follow-up was 59 months. There were 7 excellent, 11 good, and one fair result. No femoral component had been revised for loosening and all

Preparation and performance evaluation of non-foaming styrene-acrylic latex for cementing slurry
The latex used conventionally for oil-well cementing can lead to serious foaming issues in the cement slurry, which not only affects the accurate measurement of the density of the latex-containing cement slurry, but also is detrimental to cementing ...

Cement Brand and Preparation Effects Cement-in-Cement Mantle Shear Strength [PDF]
Creating bi-laminar cement mantles as part of revision hip arthroplasty is well-documented but there is a lack of data concerning the effect of cement brand on the procedure. The aim of this study was to compare the shear strength of bi-laminar cement mantles using various combinations of two leading bone cement brands. Bi-laminar cement mantles were

The production rate of a shale gas well generally declines fast, resulting in a low average recovery of the well. Refracturing of an old well with shale gas production pressure depletion can effectively enhance the ultimate recovery of the well, and ...

Displacement Efficiency of Cementing in Eccentric Annulus with Small Clearance
In the process of cementing in a small annular clearance,if the casing is eccentric seriously,drilling fluid might be detained in the narrow clearance of the annulus generally besides retention on both walls of the annulus.In order to improve the ...
