undesired radiation exposure to caregivers is an important problem in radioiodine therapy in thyroid carcinoma patients, especially when patient is non-ambulatory. special precautions are needed to keep the exposure to caregivers low when higher dose of radioiodine is necessary. here we present a case-report of a 74-year old male patient with papillary thyroid carcinoma with local invasion and ...

The development and design of servo valve spools with high performance requirements require accurately calculating the impacts on spool. During operation valve, most significant impact spool is exerted by flow force, which determined rate liquid angle deflection jet. Existing methods for magnitude force do not take into account actual shape sleeve collars, negatively affects accuracy calculatio...

Controlling spatial positioning of cattle through use of electronic collars could provide new ways to farm under extensive conditions. This study examined the potential for bulls to be controlled during mating using mild electric shocks delivered through radio-controlled collars. Eighteen Belmont Red bulls were fitted with collars containing the Global Positioning System and that were able to e...

Provably correct algorithms for meshing difficult domains in three dimensions have been recently developed in the literature. These algorithms handle the problem of sharp angles (< π/2) between segments and between facets by constructing protective collars around these regions. The collars are approximately sized according to the local feature size of the input. With the eventual goal of develo...

The objective of this study was to perform a dynamic biomechanical analysis of neck collars in order to determine their effect on head and neck loading. A total of 48 tests were performed comparing the Cowboy Collar, Bullock Collar, and Kerr Collar. A control and each collar were tested at two speeds (5 m/s and 7 m/s), three impact locations (front, top, and side of the helmet), and two shoulde...

This study investigated the efficacy of two collars for the treatment and prevention of flea infestations. Additionally the effect of these collars on the incidence of Leishmania infantum infection as compared with a group of vaccinated dogs was evaluated. A total of 224 young dogs from private animal shelters were enrolled in April/May into four groups: G1, 55 dogs treated with 10% imidaclopri...
