Nowadays, local flap coverage methods, including the C-V breast flap compose the majority of nipple reconstruction procedures [1]. As the projection of new nipple from the C-V breast flap is basically subcutaneous fat, the reconstructed nipple tends to be flattened over the long term, especially if submitted to pressure. In addition, necrosis or abrasion may result in flap failure. For this rea...

-Electromechanical wave propagation may affcet power system protective device operation. This paper discusses the testbed development to study the electromechanical wave propagation impacts on power system dynamic behavior, and consequently impacts on protective devices including overcurrent, distance, and out-of step relays. To have a better insight, a test bed to simulate electromechanical os...

The proliferation of surge-protective devices and switch-mode power supplies has radically changed the surge environment in the low-voltage AC mains. Monitoring surge voltages has lost significance and can be misleading. Instead, surge currents should be monitored. The paper describes the performance of a silicon-based surge-protective device acting as a "magnet" for impinging surges in the pre...

The case histories are presented of three adults who had severe hypercapnic acidosis despite mechanical ventilation with what were considered to be injurious tidal volumes and airway pressures. The use of a percutaneously inserted arteriovenous extracorporeal carbon dioxide removal (AV-ECCO(2)R) device facilitated a dramatic reduction in the amount of ventilatory support required, achieving a "...

background: pain adversely affects cancer patients quality of life . knowing different sources of pain helps physicians and patients to manage it. the aim of this study was investigating physical factors affecting pain in iranian cancer patients. method: this cross-sectional study randomly enrolled cancer patients who were newly admitted to the medical oncology department of cancer institute of...

mammea africana sabine (guttiferae) stembark, a common plant, traditionally used to treat various diseases and ailments was evaluated for hepatoprotective potentials against paracetamol- induced liver injury in rats. the hepatoprotective effect of the stembark extract (30-90 mg/kg) was evaluated by the assay of liver function parameters: total and direct bilirubin, serum protein and albumin, to...

It is shown that the superposed wave function of a measuring device, in each branch of which there is a definite measurement result, does not correspond to many worlds as assumed by the many-worlds interpretation, because all branches of the superposed wave function can be observed in our world by protective measurement. According to the many-worlds interpretation of quantum mechanics, each bra...

Personal Protective Equipment (PPE) is considered the last preferred solution to an Occupational Safety Health (OSH) system. Brazilian OSH legislation assumes and requires PPE usage to neutralize the possibility of pesticide contamination. This study examines the inadequacy of the PPE used in a tomato crop, particularly from the standpoint of thermal comfort. This study made observations regard...
