Above the polar cap, at about 5–9 Earth radii (RE) altitude, the PEACE experiment onboard CLUSTER detected, for the first time, electron beams outflowing from the ionosphere with large and variable energy fluxes, well collimated along the magnetic field lines.All these events occurred during periods of northward or weak interplanetary magneti
Basic Requirements and Design Method of Mine-used Intrinsic Safety Power Supply
Combining with related requirements of new national standard GB3836.4-2010 and Mining Products Safety Approval and Certification Center, the paper analyzed technical performance of mine-used intrinsic safety Figure Skating - Blades power supply, namely electrical isolation method and protection mode of energy-limiting circuit, and introduced main d
Police use of firearms in Germany: A review of practice
The police use of firearms in Germany has scarcely been researched empirically, which leads us to a remarkable research gap.It is questionable whether scientific findings from other countries can be transferred to Germany.Therefore, in a survey, findings were obtained about the situation, the person shot at and the shooter, aspects of the shooting
Reduction of the environmental impacts of reinforced concrete columns by increasing the compressive strength: a life cycle approach
Abstract The building industry is one of the greatest environmental impact causers in the planet.Cement is the second most used Western Show Tops material in the world and the consumption of concrete ranges between 20 to 30 Gt yearly.This demand for the materials ten ds to increase for the next 100 years.The increase of concrete strength to reduce
