DMPQ: Short note on Tertiary coal field.

Tertiary coal 15 to 60 million years old. Carbon content is very low.Mainly confined to the extra-Peninsula [Jammu and Kashmir, Himachal Pradesh, Assam, Arunachal Pradesh etc.]Coal generally has low carbon and high percentage of moisture and Sulphur.It takes few hundred million years for the carbon content to improve.Important areas of Tertiary coal include parts of … Read more

DMPQ:Gondwana coal field in India

Gondwana coal makes up to 98 per cent of the total reserves and 99 per cent of the production of coal in India. Satpuras, denudation [weathering + erosion] has exposed coal bearing Gondwana strata.The carbon content in Gondwana coal [250 million years old] is less compared to the  Carboniferous coal [350 million years old][Almost Absent in India] because of its much … Read more

DMPQ: Application of nanotechnology in the field of electronics and IT application. Discuss. (SCIENCE)

  Miniaturisation of the transistor size. Smaller, faster and better transistors may mean that soon your computer’s entire memory may be stored on a single tiny chip. Using magnetic random access memory (MRAM), computers will be able to “boot” almost instantly. MRAM is enabled by nanometer‐scale magnetic tunnel junctions and can quickly and effectively save … Read more

DMPQ: . Application of nanotechnology in the field of Energy application. (SCIENCE)

  Nanotechnology is improving the efficiency of fuel production from raw petroleum materials through better catalysis. It is also enabling reduced fuel consumption in vehicles and power plants through higher-efficiency combustion and decreased friction.  carbon nanotube “scrubbers” and membranes to separate carbon dioxide from power plant exhaust. Development of wires containing nano tube that will … Read more

DMPQ:Discuss the characteristics of the Chola art and their contribution in the field of art and architecture. (Ancient Art)

Cholas were great patron of art and architecture. Brihadeshwar temple and bronze sculpture of Nataraj are testimony to that. Cholas built many temples throughout their kingdoms. For example temple at Narthamalai, kumbakonam, etc. The major features of Chola art and architecture are as follows:   Architecture: Use of local stones They followed the pallava style … Read more
