Electrical burns are among the most devastating trauma inflicted on the human body. These burns have a higher morbidity, length of stay and a much higher risk of amputation than any other type of burn. Electrical burns affect mostly young, working males because they are more frequently the result of a work accident. However, possibly due to the worldwide economic crisis, we are experiencing a new phenomenon: the theft of high-voltage copper wiring.

Spring grassland fires are common in boreal areas as a consequence of slash and burn agriculture used to remove dry grass to increase soil nutrient properties and crop production. However, few works have investigated fire impacts on these grassland ecosystems, especially in the immediate period after the fire. The objective of this work was to study the short-term impacts of a spring grassland fire in Lithuania. Four days after the fire we established a 400m(2) sampling grid within the burned area and in an adjacent unburned area with the same topographical, hydrological and pedological characteristics...

Contact with high- or low-voltage electricity can cause injury. Low-voltage damage is more common and widespread, although there is little information on it in the literature. Exposure to an electrical current can effect every organ system in the body. The degree of damage is related to many factors, including the duration of exposure, type of current, and nature of the affected tissue. An unusual low-voltage electrical injury with a serious pulmonary lesion is presented, including the clinical intervention and imaging findings...

Large lead-acid batteries are predominantly used throughout the mining industry to power haulage, utility, and personnel-carrier vehicles. Without proper operation and maintenance, the use of these batteries can introduce mechanical and electrical hazards, particularly in the confined, and potentially dangerous, environment of an underground coal mine. A review of the Mine Safety and Health Administration accident/illness/injury database reveals that a significant number of injuries occur during the maintenance and repair of lead-acid batteries...

In this paper, we attempt to understand the physico-chemical changes that occur in devices during device "burn-in". We discuss the use of low frequency dielectric spectroscopy to detect, characterize and monitor changes in electrical defects present in the dielectrics of through silicon vias (TSV) for three dimensional (3D) interconnected integrated circuit devices, as the devices are subjected to fluctuating thermal loads. The observed changes in the electrical characteristics of the interconnects were traceable to changes in the chemistry of the isolation dielectric used in the TSV construction...

Micro unmanned underwater vehicles (UUVs) need to house propulsion mechanisms that are small in size but sufficiently powerful to deliver on-demand acceleration for tight radius turns, burst-driven docking maneuvers, and low-speed course corrections. Recently, small-scale hydrogen peroxide (H2O2) propulsion mechanisms have shown great promise in delivering pulsatile thrust for such acceleration needs. However, the need for robust, high surface area nanocatalysts that can be manufactured on a large scale for integration into micro UUV reaction chambers is still needed...
