Thirty-five patients with typical Prinzmetal's variant angina were studied by coronary cineangiography. There was no demonstrable stenosis of the major coronary arteries in 19 patients. Nine patients with single coronary stenosis underwent aortocoronary bypass and had recurrence of the symptoms postoperatively. Administration of nifedipine effected complete cessation of the symptoms among patie...

This paper presents a study of dynamic characteristics of spring loaded relief valve and the turbulent flow of water through it by using CFD in 2-Dimensions. Mesh deformation due to the fluid-solid interaction between the valve disc and the surrounding fluid and CEL expressions determined by solving a dynamics equation of forces acting on the valve disc, are used to account for the motion of th...

Pain is an experience that powerfully influences the way we interact with our environment. What is less clear is the influence that pain has on the way we perceive our environment. We investigated the effect that the anticipation of experimental pain (THREAT) and its relief (RELIEF) has on the visual perception of space. Eighteen (11F) healthy volunteers estimated the distance to alternating TH...

Farabloc is a product promoted for the relief (not cure) of intermittent phantom limb pain. It is a linen fabric with ultrathin steel threads to be worn over the stump and claimed to shield nerve endings from external electrical and magnetic fields. In a double blind, cross-over design, 34 subjects reported their pain relief level on a Visual Analogue Scale during a pretreatment period, Farablo...

Humor can improve a performance of creative problem solving; this phenomenon was repeatedly demonstrated in various studies. However, mechanisms underlying this phenomenon are still unclear. We analyze the possible mechanisms of how humor facilitates creative problem solving. The experiment demonstrates that preliminary humor production facilitates insight problem solving. There is no such an e...

Stock prepositioning is one of the most important issues in preparedness stage of emergency logistics response. In a previous research, a stock prepositioning model to support an emergency disaster relief response in the event of earthquake has been proposed. Since the results contained zero proportion of some type of item, which is not allowed in a real system, an improvement of the model is n...
