Solar storms are the largest explosive release of energy in the solar system and are responsible for large variations of the Earth’s magnetic field, which are known as geomagnetic storms. Magnetic storms can induce significant electric currents at the Earth’s surface disrupting the electric power distribution system, causing situations such as the collapse of the power grid in northern Canada i...

Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint racing. This study is the first to evaluate the energy requirements of working dogs trained in odor, explo...

Explosion metal welding is high-speed angle oblique collision of two or more metal plates caused by detonation. The metal is joined – welded under high dynamic pressure creating by plastic deformation the waves on the bond interface, accompanied by local adiabatic heating 1 . The explosive metal cladding process can be divided into three stages: a) generation of explosion energy through the det...

OBJECTIVE The primary purpose of this study was to compare the effects of explosive versus slow contractions on the rate of energy expenditure during and after resistance exercise. METHODS Nine men (20 +/- 2.5 yr) performed three exercise protocols using a plate-loaded squat machine, and a no-exercise (CONTROL) session in a randomly assigned, counterbalanced order. Subjects performed squats u...

We analyze the definition of the Gibbs free energy of a nanoparticle in a reactive fluid environment, and propose an approach for predicting the size of carbon nanoparticles produced by the detonation of carbon-rich explosives that regards their condensation as a nucleation process and takes into account absolute entropy effects of the cluster population. The results are consistent with experim...

The pulsed electrical excitation of reactive metals like aluminum in water triggers a fast and highly energetic chemical reaction generating gaseous products. For applications such as fuses, safe explosives or fast gas generation, it is desirable to maximize the ratio of conductor mass to stored electrical energy while rapidly attaining a high resistive state. Various techniques have been used ...

The introduction of smart phones and other smart gadgets, which offers ubiquitous internet access and other diverse multimedia applications, has lead to the explosive growth of mobile data. However, this also increases the energy consumptions and carbon footprint of the mobile communications industry. The recent advancement in green telecommunication networks explores energy saving through dyna...
