Fracturing under ultrahigh vacuum (UHV, P less than or equal to 10(-9) Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite for studies of interactions between condensing gases and distinct regions of a surface. For the study of water condensation, a device has been developed which enables production of pure water vapor and controlled variation ...

BACKGROUND Sudden emotions may interfere with mechanisms for keeping balance among the elderly. The aim of this study is to analyse if emotional stress and specifically feelings of anger, sadness, worries, anxiety or stress, can trigger falls leading to hip or pelvic fracture among autonomous older people. METHODS The study applied the case-crossover design and was based on data gathered by f...

The catalytic subunit of cellulose synthase is shown to be associated with the putative cellulose-synthesizing complex (rosette terminal complex [TC]) in vascular plants. The catalytic subunit domain of cotton cellulose synthase was cloned using a primer based on a rice expressed sequence tag (D41261) from which a specific primer was constructed to run a polymerase chain reaction that used a cD...

BACKGROUND AND OBJECTIVES Our primary objective was to determine the percentage of recreational hockey players who do not wear face protection while playing hockey. METHODS We randomly surveyed recreational hockey players at two indoor hockey rinks in Evandale, Ohio. Data were collected on face protection, injuries, demographic variables, and attitudes about protective gear. RESULTS We surv...

PURPOSE To report a case of subcutaneous emphysema involving the orbit, mediastinum, and face after pars plana vitrectomy with fluid-gas exchange. METHODS Case report of a 55-year-old man who presented with bilateral eyelid and face edema and dysphagia in the immediate postoperative period after pars plana vitrectomy. Orbital and chest computed tomographies were performed, revealing emphysema...

The fine structure of the regular arrays of subunits seen on both plasmalemma fracture faces in resting and starved Saccharomyces cerevisiae (baker's yeast) has been compared using different freeze-fracture replication methods. Freeze-cleaving was carried out at 173 degrees, 133 degrees, and 108 degrees K under a vacuum of 2 X 10(-7) torr (2.6 X 10(- 7)mbar) or under liquid nitrogen at atmosphe...

OBJECTIVE To investigate the preferences of frail older people for individualised multidisciplinary rehabilitation to promote recovery from a hip fracture. DESIGN Discrete Choice Experiment. SETTING Acute and Rehabilitation Hospitals in Adelaide, South Australia. SUBJECTS Eighty-seven patients with recent hip fracture (16 living in residential care facilities prior to fracture). METHODS...

A numerical model is presented to describe the evolution of fracture aperture (and related permeability) mediated by the competing chemical processes of pressure solution and free-face dissolution/precipitation; pressure (dis)solution and precipitation effect net-reduction in aperture and free-face dissolution effects netincrease. These processes are incorporated to examine coupled thermo-hydro...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013202633 DESCRIPTION We report a case of a patient with a 9-day history of trismus measured at 9 mm (figure 1). The trismus occurred immediately after an alleged assault with punch injuries to the face. Note the flattening of the malar process on the left hand side of the face. X-rays ...
