BACKGROUND In the last two years several cases of severe contact dermatitis related to newly acquired sofas and armchairs originating from China have been published. The responsible allergen is dimethylfumarate (DMF), an extremely potent sensitizer and irritant found in sachets inside the furniture. Recently, cases of contact dermatitis related to shoes and riding helmets have also been describ...

Introduction Excessive pronation is considered to be the cause of various overuse injuries. Thus, different mechanisms to control excessive pronation have been developed (e.g. dual density and medial support shoes). Reducing effects of shoes with extreme varus angles (VA) of 8–10° on pronation (TPR) and maximum pronation velocity (MPV) have been shown [1,2]. However, resultant GRFs, loading rat...

We introduce a new type of agent, whom we refer to as a "problem solver" (PS). The PS interacts with conventional players and wishes to respond optimally to their moves. The PS has only partial information about the moves of the other players. Unlike a regular player, the PS does not "put himself in the shoes" of other players and does not form beliefs about their moves. Rather, he treats the d...

the objective of this study was to determine the effects of different heel heights on selected gait parameters in a sample of young nigerian females. a purposive sample of eighty apparently healthy undergraduates of nnamdi azikiwe university, nnewi campus participated in the study. their mean age, height, and weight were 21.98± 1.83 years, 1.65±0.06 meters, 59.50±9.34 kilograms respectively. an...

Background Curved rocker shoes are routinely prescribed for people with diabetes in order reduce in-shoe plantar pressures. However, previous research has shown that different individuals may require different rocker outsole geometries in order to optimise pressure reduction [1,2]. This has led some researchers to suggest that every individual should try a range of possible outsole designs to i...

To calibrate our ability to predict the dynamic behavior of nuclear fireballs we have simulated the balloon detonations conducted under DNA sponsership in November of 1973. These well-instrumented shoes provide excellent data to test the reliability of hydrodynamic models for the rise and expansion of very low yield explosions. We present the results of our calculations and draw conclusions con...
