Effect of the chemical compounds of soil on the stability of excavation wall: A case study [PDF]
International Journal of Mining and Geo-Engineering, 2022 Chemical compounds of soils can remarkably affect the stability of the excavation wall. This is highlighted in soils with fine grain materials. Inter-particle chemical cementation (IPCC) increases soil cohesion and, in turn, provides more stable ...

Hemiarthroplasty: To Cement or not to Cement? A Preliminary Report
HIP International, 2004 Two hundred hemiarthroplasties were studied to compare uncemented Austin Moore and cemented Thompson's prostheses. The following variables were compared: pre-operative mobility, ASA grade, Abbreviated Mental test scores, surgeon grade, peri-operative mortality, infection rate, operation time, intra-operative fractures, dislocation rate, thigh pain and

A New Method for Calculating the Cementation Exponent of Triple-Porosity Media Reservoirs
Geofluids, 2022 The value of a cementation exponent, usually obtained by rock and electricity experiments, significantly affects the calculation of water saturation, thickness of the hydrocarbon reservoir, and recovery rate. The determination of the cementation exponent

Cement Brand and Preparation Effects Cement-in-Cement Mantle Shear Strength [PDF]
HIP International, 2014 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
