The CO2-brine dissolution homogenizes the distribution of residual CO2 and reduces the leakage risk in the saline aquifer. As a key parameter to immobilize the free CO2, the dissolution rate of CO2-brine could be accelerated through mechanisms like diffusion and dispersion, which are affected by the subsurface condition, pore structure, and background hydrological flow. This study contributed t...

Same-sex adoptive couples are increasingly visible, yet few studies have addressed relationship stability and dissolution among these couples. In this study, using a theoretical framework based on Investment Models and Vulnerability-Stress-Adaptation Theory, factors associated with dissolution and post-dissolution adjustment among 27 lesbian adoptive couples were examined across two points. At ...

The dissolution characteristics of melt granulations of paracetamol in capsule and tablet dosage form were compared to determine whether the dissolution characteristics of the granules can be actualized by formulating them as rapidly disintegrating tablets. The term melt granulation refers here to the wax-matrix granules that were formed by triturating the drug powder (paracetamol) with a melte...

OBJECTIVE We explore the impact of antiretroviral therapy (ART) on partnership acquisition and dissolution rates and changes in sexual behaviours among HIV-infected adults. DESIGN Using detailed longitudinal data from a prospective cohort of HIV-infected adults with CD4 cell count below 200 cells/μl (ART-eligible) or CD4 cell count above 500 cells/μl (pre-ART) conducted in rural KwaZulu-Natal...

It was proposed that parental divorce does not have a uniform effect on young adults’ romantic relationships and that differential outcomes depend on how young adults perceive their parents’ divorce. Using a sample of 571 young adults, structural equation modeling suggested that, compared with those from intact families, young adults whose parents divorced held a more favorable attitude toward ...

A quantitative understanding of the mechanism of human dental enamel dissolution in buffers is important because it should lead to a clear description of the causative factors in caries formation, and it can be profitably employed in the design of meaningful screening methods for potential anti-decay agents. Gray' has reported studies on enamel dissolution, concluding that the rates of dissolut...

solid solutions of ag-cu were prepared via ball milling process, for about 5-30 h. the cu-20at%ag and cu-3.64at%ag composition were investigated by x-ray diffraction technique. it was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. in addition, shifts in peak positions of silver and copper were observed with milling time. the ...

Aims The X-ray micro-tomography (micro-CT) technique has been used to visualize the microstructure of pharmaceutical granules produced by high shear wet granulation and the dynamic evolution of porosity during granule dissolution. The combination of time-resolved micro-CT imaging with UV/VIS detection of the quantity dissolved made it possible to evaluate the effective diffusion coefficient of ...

Little work has examined relationship dissolution or divorce in adoptive parents or same-sex parent couples. The current study examined predictors of relationship dissolution across the first 5 years of parenthood among a sample of heterosexual, lesbian, and gay male adoptive couples. Of the 190 couples in the study, 15 (7.9%) dissolved their relationships during the first 5 years of adoptive p...
