Gopal Chandra Bhattacharya
Gopal Chandra Bhattacharya (1 August 1895 – 8 April 1981) was an Indian entomologist and naturalist who spent most of his career at Bose Institute, Kolkata. He had no formal college degree. In 1981, the University of Calcutta awarded him an honorary Doctor of Science degree months before he died. He was awarded the Ananda Puraskar for Bengali literature in 1968, and the highest award for Bengali literature, the Rabindra Puraskar, in 1975. He published his first research papers in 1932, on life events in the body of plants. Subsequently, he also published work on bioluminescence and other botany topics, but gradually his interests shifted to entomology. He became an expert photographer, and photographed many varieties of ants, spiders, small bats and tadpoles. In total, he published 22 papers in English, including in journals such as the Natural History of the American Museum of Natural History. Science popularization In 1948 he worked with Satyendra Nath Bose (of Bose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabindra Puraskar
The Rabindra Puraskar (also Rabindra Smriti Puraskar) is the highest honorary literary award given in the Indian state of West Bengal. This award is named after the famous Indian poet Rabindranath Tagore and is administered by the Government of West Bengal under the aegis of the Paschimbanga Bangla Academy (Bengali Academy of West Bengal), Kolkata.The award is given for creative literature, non-fiction and books about Bengal in Bengali as well as other languages. From 1950 to 1982 this award was conferred on one or more writers for a particular outstanding work of him. From 1983 to 2003 this award was conferred to one or more writers as a recognition of their lifetime achievement. In 2004 and 2005, again this award was conferred on one or more writers for a particular outstanding work. Since 2006 this award again is being conferred to one or more writers as a recognition of their lifetime achievement. Sisir Kumar Das is missing from the list. He got the award twice, in 1976 and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bose–Einstein Statistics
In quantum statistics, Bose–Einstein statistics (B–E statistics) describes one of two possible ways in which a collection of non-interacting, indistinguishable particles may occupy a set of available discrete energy states at thermodynamic equilibrium. The aggregation of particles in the same state, which is a characteristic of particles obeying Bose–Einstein statistics, accounts for the cohesive streaming of laser light and the frictionless creeping of superfluid helium. The theory of this behaviour was developed (1924–25) by Satyendra Nath Bose, who recognized that a collection of identical and indistinguishable particles can be distributed in this way. The idea was later adopted and extended by Albert Einstein in collaboration with Bose. The Bose–Einstein statistics applies only to the particles not limited to single occupancy of the same state – that is, particles that do not obey the Pauli exclusion principle restrictions. Such particles have integer values of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oecophylla Smaragdina
''Oecophylla smaragdina'' ( common names include Asian weaver ant, weaver ant, green ant, green tree ant, semut rangrang, semut kerangga, and orange gaster) is a species of arboreal ant found in tropical Asia and Australia. These ants form colonies with multiple nests in trees, each nest being made of leaves stitched together using the silk produced by the ant larvae: hence the name 'oecophylla' reek for 'leaf-house' Description Workers and major workers are mostly coloured orange. Workers are long; they look after larvae and farm scale bugs for honeydew. Major workers are long, with long strong legs and large mandibles. They forage, assemble and expand the nest. Queens are typically long, and normally greenish-brown, giving the species its name ''smaragdina'' (Latin: emerald). Distribution and habitat ''Oecophylla smaragdina'' has a widespread distribution in tropical Asia and Australia, its range extending from India through Indonesia and the Philippines to Northern Ter ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Royal Jelly
Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens. It is secreted from the glands in the hypopharynx of nurse bees, and fed to all larvae in the colony, regardless of sex or caste.Graham, J. (ed.) (1992) ''The Hive and the Honey Bee'' (Revised Edition). Dadant & Sons. During the process of creating new queens, the workers construct special queen cells. The larvae in these cells are fed with copious amounts of royal jelly. This type of feeding triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. Royal jelly is sometimes used in alternative medicine under the category apitherapy. It is often sold as a dietary supplement for humans, but the European Food Safety Authority has concluded that current evidence does not support the claim that consuming royal jelly offers health benefits to humans. In the United States, the Food and Drug Administration has taken legal action against companies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worker Bee
A worker bee is any female (eusocial) bee that lacks the full reproductive capacity of the colony's queen bee; under most circumstances, this is correlated to an increase in certain non-reproductive activities relative to a queen. While worker bees occur in all eusocial bee species, the term is rarely used (outside of scientific literature) for any bees other than honey bees. Honey bee workers gather pollen into the pollen baskets on their back legs and carry it back to the hive where it is used as food for the developing brood. Pollen carried on their bodies may be carried to another flower where a small portion can rub off onto the pistil, resulting in cross pollination. A significant amount of the world's food supply, particularly fruit, depends greatly on crop pollination by honey bees. Nectar is sucked up through the proboscis, mixed with enzymes in the stomach, and carried back to the hive, where it is stored in wax cells and evaporated into honey. Life cycle Although the ...
