Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

peltier technology opens new opportunities for specialapplications. in the current project, this technology was appliedto design and fabricate a portable thermoelectric beveragecooler and thermoelectric cup. the simulation and results of theexperiment showed that the common beverage cooler is not asuitable design for ignoring the effect of natural convection incooling. in our thermoelectric cup...

PURPOSE To use novel confocal scanning ophthalmoscopy technology to test hypothesis that HIV-seropositive patients without history of retinitis with a history of a low CD4 count are more likely to have damage to their retinal nerve fiber layer (RNFL) when compared to patients with high CD4 count. In addition, we compared optic disc morphologic changes with glaucoma. DESIGN Cross-sectional stu...

PROFESSOR John Scarborough in a recent article in this journal has discussed the relationship between doctors and the Roman army, but his methods and his conclusion, which may seem to some to compel assent, demand a cautious and thorough examination before being accepted.' As Sigerist saw, it is necessary to exclude modern preconceptions and to avoid the obfuscation of an account by the introdu...

A military surgeon is a physician who works in a standard clinical field, but who also has to learn to adapt his skills to exceptional circumstances and must cope with special challenges due to his deployment in crisis regions, a fact that is one of the major factors influencing military medical strategy planning. The only certainty is that these special circumstances differ fundamentally from ...

In this paper, we present the Smart Dice Cup, a novel interaction device aimed at gaming applications in smart home environments. The Smart Dice Cup is used in a similar way as a traditional leather dice cup to generate random numbers. Integrated accelerometers relate the shaking of the device to the resulting rolls of the dice. In addition to an autonomous stand-alone mode, where the Smart Dic...
