This study sought to compare the clinical features and outcome of a first acute myocardial infarction (AMI) with onset of symptoms during or within 30 minutes of exercise, at rest and in bed. Information collected using a standard questionnaire was used to relate activity at the onset of symptoms and in-hospital outcome in 500 consecutive patients admitted to our heart center with a first ...

Recently interest in adsorption cooling systems has increased due to their capability to utilise low grade heat sources and environmentally friendly refrigerants. Currently, most of the commercially available adsorption cooling systems utilise granular packed adsorbent beds. Enhancing the heat transfer process inside the adsorbent bed will improve the overall efficiency of the adsorption system...

A high-fidelity DEM-CFD model is newly proposed for process intensification of packed bed reactors. The discrete element method (DEM) is employed for simulating random packing under gravity with hundreds of spheres in a cylindrical tube. It is verified that the DEM is capable of constituting a packed bed whose voidage well agrees with the literature according to particle-to-tube diameter ratio....

OBJECTIVES The purpose of this study was to investigate the effects of 20 days' bed rest on the viscoelastic properties of human tendon structures in knee extensor and plantar flexor muscles in vivo. METHODS Eight healthy men (age: 24+/-4 years, height: 172+/-9 m, body mass: 69+/-13 kg) carried out a 6 degrees head-down bed rest for 20 days. Before and after bed rest, elongation (L) of the te...

BACKGROUND Insecticide-treated nets (ITNs) are an integral part of vector control recommendations for malaria elimination in China. This study investigated the extent to which bed nets were used and which factors influence bed net use among Jinuo Ethnic Minority in China-Myanmar-Laos border areas. METHODS AND FINDINGS This study combined a quantitative household questionnaire survey and quali...

Objective: Bed-sharing is associated with sudden infant death syndrome and accidental suffocation and strangulation in bed. The purpose of this study was to identify risk factors for newborn bed-sharing. Methods: Postpartum mothers from a university maternity service were contacted by phone to complete a survey. Demographic and environmental data were collected; newborn bed-sharing and sleep en...
