Sequestration of CO2 into deep, unminable coal seams is an attractive option to reduce atmospheric emissions. However, coal seams commonly have low initial permeability, and CO2 adsorption causes the coal matrix to swell, which further reduces the permeability and may result in inefficient injection. We investigate numerically the impacts of coal swelling on coal permeability and, thus, CO2 injection efficiency with constraints determined by experimental adsorption-associated volumetric strain measurements on three western Canadian coals. Our results show that injecting pure CO2 markedly reduces permeability through time to the extent that it is not a feasible sequestration technology for almost all coals. (more…)

BackgroundThe compliance review (CR) is a federal program monitoring motor carrier safety performance and regulatory compliance. This study sought to assess the impact of CRs on reviewed trucking companies in reducing truck crashes.MethodsData was from the Motor Carrier Management Information System. Study subjects were trucking companies established during 1990–1995, had at least one truck, and remained active until April 2004. (more…)

IntroductionThoracic trauma secondary to motor vehicle crashes (MVC) continues to be a major cause of morbidity and mortality. Specific vehicle features may increase the risk of severe thoracic injury when striking the occupant. (more…)

OBJECTIVE: Interpersonal psychotherapy (IPT) for depression is a brief, well researched treatment for acute major depression. This article describes the implementation of IPT as an evidence-based treatment for depression in a psychiatry residency program. (more…)

BACKGROUND: Carcinoma metastatic to the pituitary gland is infrequent and hasbeen reportedly detected in approximately 1% of pituitary surgical cases. It may masquerade as apituitary adenoma both clinically and radiologically. (more…)

OBJECTIVE: Recent studies have validated the use of cytologic materials todetermine HER-2/neu status. Good concordance has been shown between results obtained byimmunocytochemistry (more…)

OBJECTIVE: To investigate the impact of keratin on the accuracy of internal and external anal brush sampling of known lesions. STUDY DESIGN: A group of 46 human immunodeficiency virus (HIV)-seropositive patients underwent external and internal anal brush sampling before biopsy of known lesions. RESULTS; (more…)
