Hyderabad's lakes and the sloping terrain of its low-lying hills provide habitat for an assortment of flora and fauna. The forest region in and around the city encompasses areas of ecological and biological importance, which are preserved in the form of national parks, zoos, mini-zoos and a wildlife sanctuary. Nehru Zoological Park, the city's one large zoo, is the first in India to have a lion and tiger safari park. Hyderabad has three national parks (Mrugavani National Park, Mahavir Harina Vanasthali National Park and Kasu Brahmananda Reddy National Park), and the Manjira Wildlife Sanctuary is about 50 km (31 mi) from the city. Hyderabad's other environmental reserves are: Kotla Vijayabhaskara Reddy Botanical Gardens, Shamirpet Lake, Hussain Sagar, Fox Sagar Lake, Mir Alam Tank and Patancheru Lake, which is home to regional birds and attracts seasonal migratory birds from different parts of the world. Organisations engaged in environmental and wildlife preservation include the Telangana Forest Department, Indian Council of Forestry Research and Education, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Animal Welfare Board of India, the Blue Cross of Hyderabad and the University of Hyderabad.

What is the name of the largest zoo in Hyderabad?

A maakond (county) is the biggest administrative subdivision. The county government (Maavalitsus) of each county is led by a county governor (Maavanem), who represents the national government at the regional level. Governors are appointed by the Government of Estonia for a term of five years. Several changes were made to the borders of counties after Estonia became independent, most notably the formation of Valga County (from parts of Voru, Tartu and Viljandi counties) and Petseri County (area acquired from Russia with the 1920 Tartu Peace Treaty).

A Maavanem holds what position in Estonia?
Answer: county governor

White LEDs can also be made by coating near-ultraviolet (NUV) LEDs with a mixture of high-efficiency europium-based phosphors that emit red and blue, plus copper and aluminium-doped zinc sulfide (ZnS:Cu, Al) that emits green. This is a method analogous to the way fluorescent lamps work. This method is less efficient than blue LEDs with YAG:Ce phosphor, as the Stokes shift is larger, so more energy is converted to heat, but yields light with better spectral characteristics, which render color better. Due to the higher radiative output of the ultraviolet LEDs than of the blue ones, both methods offer comparable brightness. A concern is that UV light may leak from a malfunctioning light source and cause harm to human eyes or skin.

The method of coating NUVs less efficient than what other LEDs?
Answer:
blue
