A horse is best mounted using a mounting block because it is easier for the rider to mount the horse, it puts less strain on the stirrup leathers when mounting and it decreases the chances of the saddle slipping to one side when mounting, thereby reducing the chances of a fall and possible injury to the rider. A horse or pony is mounted from ...
The Hopi Native Americans of Arizona use quartz crystals to assist in diagnosing illnesses. [14] Both Pliny the Elder and Galen claimed that certain crystals had medicinal properties. In Europe, the belief in the healing powers of crystals (and in particular crystal amulets) persisted into the Middle Ages .
Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). [2]
The scientists calculated that a huge reflector, made of metallic sodium and with an area of 9 square kilometres (900 ha; 3.5 sq mi), could produce enough focused heat to make an ocean boil or burn a city. [1] After being questioned by American officers, the Germans claimed that the sun gun could be completed within 50 or 100 years.

[3] An alternative technique used a similar scheme to the above except that the connections of two of the lamps were swapped either at the generator terminals or the system terminals. In this scheme, when the generator was in synchronism with the system, one lamp would be dark, but the two with the swapped connections would be of equal brightness.
Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. [1] ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. [2]
In 2010, the United States Navy tested a BAE Systems-designed compact-sized railgun for ship emplacement that accelerated a 3.2 kg (7 pound) projectile to hypersonic velocities of approximately 3,390 m/s (7,600 mph; 12,200 km/h; 11,100 ft/s), or about Mach 10, with 18.4 MJ of kinetic energy. It was the first time in history that such levels of ...
