It is well known that the shielding against out-of-field scattered radiation is not very effective on whole body PET scanners operated with their slice-defining septa retracted. Additional shielding can be employed during neurological studies since the diameter of the head is much less than the field of view required for imaging the human torso. We have designed, built and tested (on the CTI HR...

Ionizing radiation management is among the most important safety issues in interventional cardiology. Multiple radiation protection measures allow the minimization of x-ray exposure during interventional procedures. Our purpose was to assess the utilization and effectiveness of radiation protection and optimization techniques among interventional cardiologists in Lithuania. Interventional cardi...

Several papers [1, 2, 3) 2 and Handbooks [4, 5] have been published during the past 20 years dealing with barrier req uirements for shielding against gamma radiation from radium. These publications have usually suggested lead for the barriers because a large proportion of the applications required restricted space and ready transportabi lity of the barrier and gamma-ray source. For h igh-energy...

Present day cotton garments are mostly given chemical treatments like Softening, Easy care (Wrinkle free), Antimicrobial etc. Human sweat contains chemicals and some times affects the appearances of the garments. Effect of perspiration on wrinkle free treated cotton fabric on acidic and alkaline condition has been studied during this research work. It has been observed that there is no negative...

This paper investigates an analytical derivation of the distribution of the number of neutrons and photons emitted by a multiplying sample. The relationship between the statistics of the generated and detected neutrons and photons is also described. The analytical model described in this paper accounts for absorption, thus extending the model presented in previous studies. By using this new, im...

PURPOSE Compression garments have been commonly used in a medical setting as a method to promote blood flow. Increases in blood flow during exercise may aid in the delivery of oxygen to the exercising muscles and, subsequently, enhance performance. The aim of the current study was to investigate the effect of wearing lower body compression garments during a cycling test. METHODS Twelve highly...

Background:In diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. Lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiology range.Objective: Although lead aprons have good radiation protection properties, in recent years, researchers have been looking for altern...

the aim of this research was to investigate the satisfaction and loyalty of female bodybuilders towards domestic and foreign sport garments considering garments characteristics. in other words, this research attempted to answer this question that which characteristics rise female athletes' satisfaction from sport garments with special brands and consequently their loyalty so that the obtai...
