In this thesis, I study optical pumping as a powerful cooling tool for trapped ultra-cold atoms in a highly collisional regime. First application of optical pumping is a continuous loading scheme used to transfer atoms from a guided beam into a hybrid trap. Further, I introduce a Sisyphus cooling scheme based on radio-frequency transitions and optical pumping, operating simultaneously to the ac...

Although systemic cooling had recently been reported as effective in improving the neurological outcome after traumatic brain injury, several problems are associated with whole-body cooling. The present study was conducted to test the effectiveness of brain cooling without interference with the core temperature in rats after fluid percussion traumatic brain injury (TBI). Brain dialysates ischem...

This paper introduces a new global analytical model of the heat dissipation process that occurs in passively-cooled embedded systems, and explicits under what circumstances the folklore assumption that exponential cooling laws apply in such context is valid. Since the power consumption and reliability of microprocessors are highly dependent on temperature, both designers and, later on, run-time...

peri-implantitis is one of the most common reasons for implant failure. decontamination of infected implant surfaces can be achieved effectively by laser irradiation; although the associated thermal rise may cause irreversible bone damage and lead to implant loss. temperature increments of over 10ºc during laser application may suffice for irreversible bone damage.the purpose of this study was ...

Ionization cooling of muon beams is a crucial component of the proposed muon collider and neutrino factory. Current studies of cooling channels predominantly use simulations which track single particles, an often time consuming procedure. These simulation efforts are discussed and compared with analytic studies using equations for the beam moments in a linear channel. These dynamic equations, w...

Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...
