The Desert National Park in Jaisalmer is spread over an area of 3,162 square kilometres (1,221 sq mi), is an excellent example of the ecosystem of the Thar Desert and its diverse fauna. Seashells and massive fossilised tree trunks in this park record the geological history of the desert. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrels and vultures. Short-toed eagles (Circaetus gallicus), tawny eagles (Aquila rapax), spotted eagles (Aquila clanga), laggar falcons (Falco jugger) and kestrels are the commonest of these.
What types of large fossils are found in Desert National Park?
A: massive fossilised tree trunks

Motorsport racecourses and events were banned in Switzerland following the 1955 Le Mans disaster with exception to events such as Hillclimbing. During this period, the country still produced successful racing drivers such as Clay Regazzoni, Sebastian Buemi, Jo Siffert, Dominique Aegerter, successful World Touring Car Championship driver Alain Menu, 2014 24 Hours of Le Mans winner Marcel Fässler and 2015 24 Hours Nürburgring winner Nico Müller. Switzerland also won the A1GP World Cup of Motorsport in 2007–08 with driver Neel Jani. Swiss motorcycle racer Thomas Lüthi won the 2005 MotoGP World Championship in the 125cc category. In June 2007 the Swiss National Council, one house of the Federal Assembly of Switzerland, voted to overturn the ban, however the other house, the Swiss Council of States rejected the change and the ban remains in place.
What was banned in Switzerland in 1955 after the Le Mans disaster?
A: Motorsport racecourses and events

Alloys are often made to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility, or other desired properties. Most metals and alloys can be work hardened by creating defects in their crystal structure. These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized. However, some alloys can also have their properties altered by heat treatment. Nearly all metals can be softened by annealing, which recrystallizes the alloy and repairs the defects, but not as many can be hardened by controlled heating and cooling. Many alloys of aluminium, copper, magnesium, titanium, and nickel can be strengthened to some degree by some method of heat treatment, but few respond to this to the same degree that steel does.
Softening metals can be achieved by?
A: annealing
