This paper presents an efficient method of microbialinduced calcite precipitation (MICP) for cementation of sand particles. First, the influence of initial pH value of the culture medium on the growth of bacteria was discussed. Then, the compressive strength and calcium carbonate content of cemented sand columns with different sand particle sizes were measured to indie the cementation ...

· The siltstone reservoir with many small layers of pay zones is usually produced by slant holes. However, severe sand blockages take place when the siltstone reservoir is developed by slant holes. Currently, the sand blocking mechanisms and the effect of sand blocking on productivity of slant well are still challenges for engineers and scholars. In this paper, based on the existing productivity ...

This review appraises a total of 52 experimental studies that have sought to identify mechanisms and intermediate endpoints underlying epidemiological evidence of an impact of desert dust on cardiovascular and respiratory health. Toxicological studies, in main using doses that reflect or at least approach real world exposures during a dust event, have demonstrated that sand dust ...
Mechanisms of creep at elevated temperatures lead to AE and that achieve strain at short times and long times in the presence of water also are responsible for strain at long times in the dry experiments. The At all conditions tested, the quartz sand exhib microstructure observation that the degree of its transient, decelerating creep [28,29]. Volume fracturing in the dry, longterm creep ...
Reduction of trans[Pt(CN)4Cl2]2 (as a model compound for antitumoractive platinum(IV) complexes) by thiols, RSH (thioglycolic acid, lcysteine, dlpenicillamine, and glutathione), has been studied in a M aqueous perchlorate medium by use of stoppedflow spectrophotometry at 25 °C in the interval × 106 ≤ [H+] ≤ M. Timeresolved spectra show that redox takes place ...
We use the synthesized molecules and molecular materials to study complex reaction mechanisms and uncover design rules for desired reactivities. The techniques heavily utilized for all projects include NMR, electrochemistry, optical spectroscopy (steadystate and timeresolved), Xray diffraction, Xray photoelectron spectroscopy, electron microscopy, and synchrotronbased techniques. We are ...
