We describe the floor used as the skin of the playful interactive space Ada, which was part of the Swiss National Exhibition Expo.02. The floor consisted of 360 hexagonal tiles, each of which comprised an aluminum frame, a glass top, a microcontroller, analog load sensors, and dimmable red, green, and blue neon lamps. A factory automation bus sensed and controlled the tiles. We developed softwa...
background: inhalation of radon and its short-lived decay products is one of the most significant sources of exposure to natural radiation. radon is the second cause of lung cancer in the populations. the present study was carried out under the projects of national radon, with the aim of determining the concentration of indoor in the city of qom located in the central semi-arid region of ir...
UNLABELLED We characterized the prevalence of cockroach allergen exposure in a nationally representative sample of U.S. homes and assessed risk factors for elevated concentrations. DESIGN We used data from the National Survey of Lead and Allergens in Housing, a population-based cross-sectional survey. PARTICIPANTS Participants were residents of 831 U.S. homes in the survey. EVALUATIONS/ME...
Falls precipitated by slipping are listed among the leading causes of injuries. The biomechanical analysis of such events is a necessary component of the slips/falls prevention research. One of the challenges of biomechanical studies is reproducing the unexpected nature of real-life slipping accidents. Thus, the goal of this study was to quantify changes in gait biomechanics when subjects antic...
Necrotizing fasciitis (NF) is a rare but life-threatening medical and surgical emergency. It is characterized by necrosis of the soft tissue leaving the overlying tissue unaffected, which delays the diagnosis and treatment. Delay in recognition of the severity of necrotizing fasciitis might lead to serious morbidity and mortality. Diagnosis of NF relies on strong clinical judgment, predictable ...
Research suggests that abattoir holding pens pose significant Salmonella enterica risk to swine immediately preharvest. The goal of this study was to evaluate those factors related to holding that increased the prevalence of S. enterica in swine at slaughter. To accomplish this goal, we focused on holding time and flooring. Our objectives were to (1) compare Salmonella enterica prevalence among...
Dust layers on the bottom of mine tunnels, on fac toy floors, or on the floors of gruin elevator passages are the most frequent cause of highly destructive dust explosions. Typically, such layered dust explosions involve a high velocity, acceleruting, turbulent flame which is fed by the dust layer and results in high clestructivt' static and dynamic pressures. In some cases transition to detona...
