Background: Bioactive glasses 58S, are silicate-based materials containing calcium and phosphate, which dissolved in body fluid and bond to the bone tissue. This type of bioactive glass is highly biocompatible and has a wide range of clinical applications. Methods: The 58S glass powders were synthesized via sol-gel methods, using tetraethyl orthosilicate, triethyl phosphate, and calcium nitrate...

The conductance and thermoelectric power (TEP) of graphene is simultaneously measured using a microfabricated heater and thermometer electrodes. The sign of the TEP changes across the charge neutrality point as the majority carrier density switches from electron to hole. The gate dependent conductance and TEP exhibit a quantitative agreement with the semiclassical Mott relation. In the quantum ...

Resistivity and thermoelectric power (TEP) measurements on CeFe2 and two of its pseudo-binaries Ce(Fe, 5% Ir)2 and Ce(Fe, 7% Ru)2 between 78K and 275K are reported. The resistivity data are analysed in terms of contributions from scattering due to phonon, magnon, spin fluctuation and lattice defects, and also from interband scattering. Attempts are made to analyze the TEP data in terms of these...

T racheoesophageal puncture (TEP) is the preferred method for voice restoration following total laryngectomy. While several techniques for secondary puncture have been described, most require general anesthesia or intravenous sedation. Techniques for in-office, unsedated secondary TEP have been developed but are limited due to patient discomfort, inability to maintain direct visualization of th...

Organosilanes bearing a phosphine imide moiety were synthesized and crystallographically characterized. Reaction of the pentacoordinated hydrodiphenylsilyl derivative with water gave [2-(diphenylphosphino)phenyl]diphenylsilanol accompanied by both reduction of the phosphine imide moiety and hydrolytic oxidation of the Si-H moiety.

Gravitational sinking of particles is a key pathway for the transport particulate organic carbon (POC) to deep ocean. Particle size and composition influence particle velocity thus play critical role in controlling flux. Canonically, that reach mesopelagic are expected be either large or ballasted by minerals. However, presence transparent exopolymer (TEP), which positively buoyant, may also ve...

A physical model of turbulent equipartition (TEP) of plasma angular momentum is developed. We show that using a simple, model insensitive ansatz of conservation of total angular momentum, a TEP pinch of angular momentum can be obtained. We note that this term corresponds to a part of the pinch velocity previously calculated using quasilinear gyrokinetic theory. We observe that the nondiffusive ...

AIM The purpose of the study was to compare the results of laparoscopic inguinal hernia repair using two different methods: transabdominal preperitoneal (TAPP) repair and the technique of totally extraperitoneal repair (TEP). METHODS In this retrospective study were included 90 cases of inguinal hernia that underwent for laparoscopic approach of inguinal hernia repair at the Emergency County ...

To examine the potential impact of fluid dynamic boundary layers on cutaneous ion exchange, we investigated how bulk flow of dilute Na+ solutions (< or = 1.0 mmol l-1) over the skin of intact frogs (Rana catesbeiana and Rana pipiens) affects cutaneous Na+ uptake (JNa(in)) and transepithelial potential (TEP). Cessation of stirring resulted in a 14-35% decrease in TEP and a 14-65% decrease in JNa...

O tromboembolismo pulmonar (TEP) é uma emergência cardiovascular comum, com apresentação clínica inespecífica e de difícil diagnóstico. A estratificação da gravidade do TEP deve ser analisada precocemente e estimada de forma individualizada, baseada no risco de morte hospitalar e a curto prazo (30 dias) com recurso a marcadores de risco. A estratificação rápida e com acuidade no TEP tem-se foca...
