BACKGROUND AND PURPOSE We noticed that our instruments were often too hot to touch after preparing the femoral head for resurfacing, and questioned whether the heat generated could exceed temperatures known to cause osteonecrosis. PATIENTS AND METHODS Using an infra-red thermal imaging camera, we measured real-time femoral head temperatures during femoral head reaming in 35 patients undergoin...

abstract background: weather and climate play a significant role in human health. we are accustomed to affects the weather conditions. by increasing or decreasing the environment temperature or change of seasons, some diseases become prevalent or remove. this study investigated the role of temperature in cardiovascular disease mortality of city of mashhad in the current decade and its simulatio...

in order to evaluate cardinal temperatures and optimum thermal range of germination of three medicinal plants including ajowan, fennel and dill an experiment was conducted in a completely randomized design with three replications. temperatures considered for this study were: 5, 10, 15, 20, 25, 30 and 35 ?c. results indicated that temperature affected germination rate and percentage of these cro...

Organismal performance abilities occupy a central position in phenotypic evolution; they are determined by suites of interacting lower-level traits (e.g., morphology and physiology) and they are a primary focus of natural selection. The mechanisms by which higher levels of organismal performance are achieved during evolution are therefore fundamentally important for understanding correlated evo...

BACKGROUND The major cause of cemented Total Knee Arthroplasty (TKA) failure is aseptic loosening of the tibial component necessitating revision surgery. Recently, multiple techniques have been described to maximize cement penetration depth and density in the proximal tibia during TKA to potentially avoid early loosening. While cement polymerisation is an exothermic reaction, minimal investigat...

Abstract In 2016, the Royal Dutch Meteorological Office (KNMI) homogenized daily temperature records for Netherlands from 1901 to 1950 allow a realistic comparison of temperatures present. The homogenizations main station De Bilt were carried out using Percentile Matching Method (PMM) with one reference and 56-month period. this study, it is shown that corrections in number tropical days (maxim...
