OBJECTIVE To compare bioresorbable plates with titanium plates for treatment of mandibular fractures. STUDY DESIGN Randomized controlled trial. PLACE AND DURATION OF STUDY Oral and Maxillofacial Surgery Department, Armed Forces Institute of Dentistry, Rawalpindi, from January to December 2010. METHODOLOGY Patients with mandibular fracture were randomly divided in to two groups. The contro...

TASAKI, I. AND A. F. BAK. Discrete threshold and repetitive responses in the squid axon under ‘voltage-claw@ By using the so-called voltage-clamp technique, records were obtained indicating the presence of undulatory or oscillatory membrane current under fixed potential difference between the internal and external electrodes. This oscillatory membrane current was observed only when rectangular ...

Oscillatory integrals over fan-shaped regions widely exist in scattering analysis, and this paper proposes a new rapid calculation routine for them. In the routine, the concerned bivariate scattering oscillatory integral is reduced to the calculation of two univariate oscillatory integrals. One is calculated with the improved Levin quadrature method, and another is transformed to a non-oscillat...

Fast evaluation of oscillatory integrals is an issue attracts much attention in many fields. In this paper, we are interested in the calculation of canonical oscillatory integrals, and the irregular oscillatory integrals are transformed into canonical ones with respect to the presences of stationary phase points or not. An improved-Levin method is proposed to calculated the canonical oscillator...

mount bidkhan stratovolcano is located in the central iranian volcanic belt. it is composed of several types of pyroclastic deposits, lava flows and intrusive bodies. textural and chemical characteristics of plagioclase phenocrysts from the eruptive products volcanic edifice, record complex magma mixing events over the lifetime of the volcano. evidences such as xenocrystic high al+ti clinopyrox...

We performed biomechanical comparison of a xenograft bone plate-screw (XBPS) system for achieving cadaveric lumbar transpedicular stabilization (TS) in dogs. Twenty dogs' cadaveric L(2-4) lumbar specimens were harvested and their muscles were removed, but the discs and ligaments were left intact. These specimens were separated to four groups: the L(2-4) intact group as control (group I, n = 5),...
