Ans. Uranium, They are owned by Uranium Corporation of India, Ltd. (UCIL).
Jharkhand mines and minerals seem to be synonymous with the territory of Jharkhand. Jharkhand possesses a large reserve of mineral wealth within the territory: coal, iron ore, copper ore, bauxite, mica, graphite, kyanite, sillimanite, limestone, etc. form an integral part of mining industry in Jharkhand.
An estimate of the major mines and minerals of Jharkhand are as follows:
| District | Important Minerals in Jharkhand | Other Minerals |
|---|---|---|
| Deoghar, Dhanbad. | Coal | Fire Clay,Silver. |

Current Status Of Radars Network in IMD
l Radar Network of India Meteorological Department, at present, has 14 S-band and 25 X-band radar and radars including 5 DWRs.
l Out of 14 S-band radars, 11 are installed at Kolkata, Paradip, Visakhapatnam , Machilipatnam, Chennai, Sriharikota, Karaikal, Kochi , Mumbai, Goa and Bhuj and are used for cyclone detection. 5 installed at Chennai, Kolkata, Visakhapatnam Visakhapatnam Kochi , Goa , Mumbai, Bhuj and. Paradip are analogue type. 2 S-band radars at Sriganganagar & Jaisalmer are used for storm detection and one radar at HQ is used for training & testing purpose.
l Out of 25 X-band radars, 9 installed at Kolkata, Chennai, Guwahati, Ranchi , Delhi , Lucknow , Mumbai, Nagpur
l X-band radar installed at Srinagar
l S-band radar at Karaikal has been upgraded by NASA , USA
l It is also planned to replace the remaining existing old conventional CDRs by the state of art S – Band Doppler Weather Radar in a phased manner. Doppler Weather Radars provide vital information on radial velocity within a tropical cyclone which is not available in conventional radar.
l Conventional radar provides information only on reflectivity whereas Doppler Weather Radars provide information on velocity and spectral width in addition to reflectivity.
l Various Meteorological, Hydrological and Aviation products derived from Doppler Weather Radar data using a variety of software algorithms are very useful for forecasters in estimating the storm’s center, its intensity, fixing its position and predicting its future path and safe navigation of aircrafts and ships.
l India Meteorological Department is modernising its observational network. Modernisation program includes replacement of all the radars with Doppler Weather Radars in phased manner. Doppler Weather Radars will also be installed at some new locations to fill data gaps.
l Under 1st phase of modernization, 12 old and obsolete radars at Delhi, Patiala, Lucknow, Patna, Mohanbari, Agartala, Paradip, Bhopal, Nagpur, Goa, Karaikal and Hyderabad will be replaced by DWRs procured from M/s Beijing Metstar Radar Company Ltd Beijing, China. 2 indigenous DWRs manufactured by M/s BEL, Bangalore will be installed at Mumbai and Kochi
l One Doppler Weather Radar procured from M/s Beijing Metstar Radar Company Ltd Beijing , China Hyderabad
l Out of two Doppler Weather Radars manufactured by M/S BEL, Bangalore
l Old and obsolete conventional radars installed at Delhi , Mumbai, Goa , Bhuj, Mohanbari have been decommissioned and dismantled to give way for building construction and installation of Doppler Weather Radars.
l Two C-Band Radars are also under procurement. These will be installed at Delhi (HQ) and Jaipur. These are expected to be installed / commissioned before Oct, 2010 under 1st phase of modernisation.
l 34 more Doppler Weather Radars, having dual polarization capability will be in 2nd and 3rd phase of modernisation. Some of them will replace old and obsolete conventional radars.
l India Meteorological Department has also plans to establish of National Weather Radar Operation Centre (NWROC) which will be responsible for maintenance of India Meteorological Department’s radar network, archival and dissemination of data, development of algorithms for new products, network planning and Research and Development.
l The existing digital Doppler Weather Radars have been networked through VPN connectivity together and to a server located at India Meteorological Department HQ, New Delhi
l The data is being received at the server and processed by SIGMET IRIS software installed on it for generating composite image . The software also converts format of the raw data to NetCDF, HDF5, UF and BUFR Oper for assimilating into NWP models and for ingesting in SYNERGY system supplied by MFI.
Recently we read in the newspapers that Indian Meteorological Department is modernizing its observational network by replacing its old and conventional radar by the state of art S-band Doppler Weather Radar (DWR) in a phased manner at different locations all over the country. A Doppler Weather Radar (DWR) would provide short-range accurate weather prediction in a radius of __500kms_____

Nepanagar
Nepanagar is a city and a municipality in Burhanpur district in the Indian state of Madhya Pradesh. Nepanagar is famous for its newspaper paper mill, Nepa Mills Limited (earlier known as The National News Print Ltd). It is also notable for its small railway station on the central railway between Burhanpur and Khandwa.
आगरा
Agra (English pronunciation: /ˈɑːɡrə/; Hindi: आगरा, Urdu: آ گرہ) is a city on the banks of the Yamuna River in the northern state of Uttar Pradesh, India. It finds mention in the epic Mahābhārata where it was called Agrevaṇa (अग्रेवण), or 'the border of the forest'.[1] Legend ascribes the founding of the city to Rājā Badal Singh (around 1475), whose fort, Badalgarh, stood on or near the site of the present Fort. However, the 11th century Persian poet Mas'ūd Sa'd Salmān writes of a desperate assault on the fortress of Agra, then held by the Shāhī King Jayapala, by Sultan Mahmud of Ghazni.[2] Sultan Sikandar Lodī was the first to move his capital from Delhi to Agra in the year 1506; he died in 1517 and his son Ibrāhīm Lodī remained in power there for nine more years, finally being defeated at the Battle of Panipat in 1526.[3] It achieved fame as the capital of the Mughal emperors from 1526 to 1658 and remains a major tourist destination because of its many splendid Mughal-era buildings, most notably the Tāj Mahal, Agra Fort and Fatehpūr Sikrī, all three of which are UNESCO World Heritage Sites.
सिक्किम
Sikkim (Nepali: 
सिक्किम (help·info), Tibetan: འབྲས་ལྗོངས་,'bras ljongs;Denzong[1]) is a landlocked Indian state nestled in the Himalayas. It is the least populous state in India and the second-smallest in area after Goa. The thumb-shaped state borders Nepal in the west, the Tibet Autonomous Region of China to the north and the east and Bhutan in the southeast. The Indian state of West Bengal borders Sikkim to its south.[3] Despite its small area of 7,096 square kilometers (2,740 sq mi), Sikkim is geographically diverse due to its location in the Himalayas. The climate ranges from subtropical to high alpine. Kangchenjunga, the world's third-highest peak, is located on the border of Sikkim with Nepal.[4] Sikkim is a popular tourist destination owing to its culture, scenic beauty and biodiversity.
