objective: the aim of this study was to measure and compare the transverse strength and deflection of two acrylic resins. method and materials: a total of 30 samples, with dimensions of 2.5×10×65mm, were prepared with acropars and meliodent acrylic resins according to ada specification no. 12. the specimens were divided into two groups of 15 samples each. a three-point bending test was carried ...

We show how macroscopic manifestations of P (and T ) symmetry breaking can arise in a simple system subject to Aharonov-Bohm interactions. Specifically, we study the conductivity of a gas of charged particles moving through a dilute array of flux tubes. The interaction of the electrons with the flux tubes is taken to be of a purely Aharonov-Bohm type. We find that the system exhibits a non-zero...

BACKGROUND The cardiac myocyte t-tubular system ensures rapid, uniform cell activation and several experimental lines of evidence suggest changes in the t-tubular system and associated excitation-contraction coupling proteins may occur in heart failure. METHODS AND RESULTS The organization of t-tubules, L-type calcium channels (DHPRs), ryanodine receptors (RyRs) and contractile machinery were...

Unintegrated partons to describe the P T distributions of electroweak bosons at hadron colliders Abstract We describe the use of unintegrated parton distributions in hadron-hadron collisions, using the (z, k t)-factorisation prescription where the transverse momentum of the incoming parton is generated in the last evolution step. We apply this formalism to calculate the transverse momentum (P T...

AIMS Ca(2+)-induced Ca(2+) release (CICR) is critical for contraction in cardiomyocytes. The transverse (t)-tubule system guarantees the proximity of the triggers for Ca(2+) release [L-type Ca(2+) channel, dihydropyridine receptors (DHPRs)] and the sarcoplasmic reticulum Ca(2+) release channels [ryanodine receptors (RyRs)]. Transverse tubule disruption occurs early in heart failure (HF). Clinic...

We analyze xF dependence of the Drell-Yan transverse momentum broadening in hadron-nucleus collisions. In terms of generalized factorization theorem, we show that the xF dependence of the transverse momentum broadening, ∆〈q2 T 〉(xF ), can be calculated in perturbative QCD. We demonstrate that ∆〈q2 T 〉(xF ) is a good observable for studying the effects of initial-state multiple scattering and ex...
