The motivation for this research arises from recent interest in actuators made from \smart mate-rials" such as shape memory alloys and piezoceram-ics. One common characteristic among these new materials is that they exhibit complex hysteresis non-linearities. The input-output nature of the Preisach model of hysteresis results in a simple model for which identiication strategies are known, and i...

There is a wide variety of dental alloys, ranging from nearly pure gold and conventional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1). The types of dental alloys have increased significantly since 1980s in order to change the market price of gold and palladium. Although gold alloys are the mate‐ rials of choice in this a...

L s he role of plasma aldosterone concentration (PAC) in the athogenesis of hypertension took an interesting turn a few ears ago when several clinical trials claimed a higher revalence of primary hyperaldosteronism in patients hought to have primary or essential hypertension, particuarly those with resistant hypertension (1). A few clinical rials demonstrated that, on the basis of these data, t...

in the present health care environment, cost-benefit analysis is extremely important. in this screening program, the minimal cost of screening dipstick urinalysis in 1601 asymptomatic school children was determined. the process of screening was similar to all the studies. the minimal cost utilizing 3 general physicians was calculated. costs were determined by using current charge for supplies o...

Background: Thalassemia is a series of hemoglobinopathies in which the production of perfect hemoglobin is completely or partially suppressed. Using injectable iron chelators have been dominating treatment for the iron overload caused by recurrent blood transfusions in thalassemic patients, however, a new oral iron chelating drug (Exjade) have been recently introduced and might be cost effec...

This study aims to give data concrning phantom material made in Iran i'rom a natural rubber which is used for obtaining calibration data for patient dose measurements in nuclear medicine applications of radionuclides for therapy and diagnosis. Is showed to be a tissue equivalent material cheap (25000 Rials the material itself and 35000 Rials the process of casting and moulding etc.), easi...
