Space travel induces many deleterious effects on the flight crew due to the '0' g environment. The brain experiences a tremendous fluid shift, which is responsible for many of the detrimental changes in physical behavior seen in astronauts. It therefore indicates that the brain may undergo major changes in its protein levels in a '0' g environment to counteract the stress. Analysis of these glo...

background: the present study aimed to investigate the effects of work shifts and mental workload on chronic fatigue among female nurses in intensive care units of selected hospitals in shiraz.   methods: the participants in this cross-sectional study were 118 female nurses working in intensive care units of three hospitals in shiraz with an average age of 304.8± years. sp (samn-perelli) mental...

This research aimed at evaluating the types and frequency of category shifts in the Persian translations of English poems based on Catford’s model of shifts. To this end, three English romantic poems of A Histo- ry of English Literature, namely, Blake’s ‘The Chimney Sweeper’, Coleridge’s ‘Kubla Khan’, and Keats’ ‘To Autumn’ along with their Persian t...

‎in the following text for arbitrary $x$ with at least two elements‎, ‎nonempty countable set $gamma$‎ ‎we make a comparative study on the collection of generalized shift dynamical systems like $(x^gamma,sigma_varphi)$ where $varphi:gammatogamma$ is an arbitrary self-map‎. ‎we pay attention to sub-systems and combinations of generalized shifts with counterexamples regarding devaney‎, ‎exact dev...

This study evaluated the extent of water penetration through resin-dentin interfaces before and after being sealed with adhesives. Four adhesive resin systems (2 total-etch adhesives and 2 self-etching primer adhesives) were used in this study. Dentin disks were placed in a split-chamber device, and in situ fluid movement across dentin was measured, with and without physiological pressure, duri...

Alterations of species phenology in response to climate change are now unquestionable. Until now, most studies have reported precocious occurrence of life cycle events as a major phenological response. Desynchronizations of biotic interactions, in particular predator-prey relationships, are however assumed to strongly impact ecosystems' functioning, as formalized by the Match-Mismatch Hypothesi...
