objective(s): the aim of the present study was to evaluate the effect of quercus brantii galls extract on the rat skin burn wound healing. materials and methods: ethanol extract of the galls of q. brantii was used to treat the induced burn wounds on the back of 32 wistar rats divided into 4 groups. the groups were treated by placebo, 1%, 2% and 4% concentration gall extract gels for 14 days and...

I discuss QCD sum rules determinations of the form factors governing the decay B → π(ρ)lν. For some of these form factors the computed dependence on the momentum transferred does not agree with the expectation from the nearest pole dominance hypothesis. Relations are observed among the form factors, that seem to be compatible with equations recently derived by B.Stech. The measurement of a numb...

BACKGROUND Most sedentary behavior measures focus on occupational or leisure-time sitting. Our aim was to develop a comprehensive measure of adult sedentary behavior and establish its measurement properties. METHOD The SIT-Q was developed through expert review (n = 7), cognitive interviewing (n = 11) and pilot testing (n = 34). A convenience sample of 82 adults from Calgary, Alberta, Canada, ...

In the measurement of a continuous observable Q, the pure components of the reduced state do, in general, depend on the initial state. For measurements which attempt to localize the measured system in a certain region R, the localized wave functions are proportional to the original wave function outside of R. This “quantum memory” effect shows that it is not possible to perfectly localize a qua...
