Large-scale vibrating coil magnetometer for the magnetic characterization of bulk superconductors.

This work presents the design and validation of a vibrating coil magnetometer for the characterization of the field dependence of the critical current density of centimeter-sized bulk superconductors as an alternative to the destructive methods typically used. The magnetometer is also shown to be capable of measuring the magnetic moment in an applied field of up to 5 T for diverse magnetic materials, such as soft and hard ferromagnets and high-temperature superconducting pellets. The vibrating coil magnetometer was first optimized using finite element simulations and calibrated using a commercial vibrating sample magnetometer.

The impact of anti-stalking training on front line service providers: using the anti-stalking training evaluation protocol (ASTEP).

The Anti-Stalking Training Evaluation Protocol (ASTEP) was developed to provide Safe Horizon, a large victim service provider, with an opportunity to evaluate and improve its anti-stalking training program. This report presents the results of this effort to measure Safe Horizon staff's knowledge and general perceptions about stalking, and to assess the impact of anti-stalking training on knowledge about the anti-stalking law, and stalking in general. Although these trainees appeared familiar with stalking issues, they were able to benefit from information about different types of stalkers and stalking, and about the legal options available to victims.

Changing clinical practice. Prospective study of the impact of continuing medical education and quality assurance programs on use of prophylaxis for venous thromboembolism.

Objective: To determine the effect of continuing medical education (CME) with and without a quality assurance component (CME+QA) on physician practices in the prevention of venous thromboembolism.

Methods: A communitywide study was performed in 15 short-stay hospitals in central Massachusetts. The study population included 3158 patients in acute-care hospitals with multiple risk factors for venous thromboembolism.

The prevalence of risk factors for venous thromboembolism among hospital patients.

Background: This study provides an estimate of the prevalence of risk factors for venous thromboembolism among hospital patients.

Methods: The presence of risk factors for venous thromboembolism was determined from a retrospective review of the medical records of 1,000 randomly selected patients in 16 acute care hospitals in central Massachusetts.

Results: The most common risk factors for venous thromboembolism were age 40 years (59%) or more, obesity (28%), and major surgery (23%).

Physician practices in the prevention of venous thromboembolism.

Objective: To determine the rate of use of prophylaxis for venous thromboembolism in high-risk hospital patients.

Design: A retrospective medical record review.

Setting: A community-wide study in 16 short-stay hospitals in central Massachusetts.

A population-based perspective of the hospital incidence and case-fatality rates of deep vein thrombosis and pulmonary embolism. The Worcester DVT Study.

A community-wide study was conducted in 16 short-stay hospitals in metropolitan Worcester, Mass, to examine the incidence and case-fatality rates of deep vein thrombosis and pulmonary embolism in patients hospitalized between July 1, 1985, and December 31, 1986. The average annual incidence of deep vein thrombosis alone was 48 per 100,000, while the incidence of pulmonary embolism with or without deep vein thrombosis was 23 per 100,000. The incidence rates of deep vein thrombosis and pulmonary embolism increased exponentially with age.

Rat intestinal microvillus membrane sucrase-isomaltase is a single high molecular weight protein and fully active enzyme in the absence of luminal factors.

Sucrase-isomaltase immunoprecipitated from brush border of an intestinal transplant lacking pancreatic proteases was found to be a single, high molecular weight protein. Elastase digestion converted this protein into two subunits which co-migrated on electrophoresis with those normally found on the microvillus membrane. The high molecular weight form had full sucrase and isomaltase activities.
