Influence of Culture Medium on Cementation of Coarse Grains Based on Microbially Induced Carbonate Precipitation

open access: yesCrystals, 2022
A main challenge in the large-scale application of the microbially induced carbonate precipitation (MICP) technique includes the low efficiency of the cementation of coarse grains.

Analysis of effective parameters on cadmium cementation reaction from the perspective of diffusion [PDF]

open access: yesJournal of Particle Science and Technology, 2021
Cadmium is one of the impurities to be removed from the electrolyte solution before zinc electrowinning. Removal of cadmium by cementation with zinc powder is diffusion-controlled.

Hemiarthroplasty: To Cement or not to Cement? A Preliminary Report

open access: yesHIP 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

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]

open access: yes, 2004
The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

A New Method for Calculating the Cementation Exponent of Triple-Porosity Media Reservoirs

open access: yesGeofluids, 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]

open access: yesHIP 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

Charnley femoral cemented stem with a permeable and resorbable cement restrictor and low-viscosity cement

open access: yesSICOT-J, 2019
Introduction: In 1979, in his first book dealing with low-friction arthroplasty (LFA), Charnley highlighted the use of a cement restrictor. Breusch and Malchau described in 2005 the “second-generation cementing technique.” The main objective of this ...

Investigating electrical response to water saturation of Agbada sandstone in an x-field Niger delta, Nigeria [PDF]

open access: yes, 2019
In an attempt to characterize a reservoir in a field, importance is given to living models as it serves critical function in estimating if the reservoir under study is economically viable. Having a good knowledge of electrical response to reservoir rocks
