Ganapathi Thanikaimoni
Ganapathi Thanikaimoni (1 January 1938 – 5 September 1986), often referred to as Thanikaimoni was an Indian palynologist. Early life and education Born on New Year's Day, 1938 in Madras, India, Thani received the Master of Science degree in botany in 1962 at the Presidency College, Madras under the direction of the plant morphologist, Professor B.G.L. Swamy. At the same time Thani was awarded the Fyson Prize in Natural Science, which is reserved for outstanding Indian naturalists. In 1970 Thani was granted a doctorate degree by the university of Montpellier. His thesis was on the pollen morphology, classification and phylogeny of 800 species of extant Palmae (Arecaceae). Scientific career Thani took a position of scientist in the newly founded (1960) Palynology Laboratory of the French Institute of Pondicherry (french: Institut Français de Pondichéry) under the direction of Dr. Prof. Guinet. In a few years Thani's scientific and administrative abilities were reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thani
The House of Thani ( ar, الثاني , translit=Al Thani) is the ruling family of Qatar, with origins tracing back to the Banu Tamim tribal confederation. History and structure The Al Thanis can be traced back to Mudar bin Nizar. The tribe were settled at Gebrin oasis in southern Najd (present-day Saudi Arabia) before they moved to Qatar. Around the 17th century, the tribe lived in Ushayqir, a settlement north-east of Riyadh. They settled in Qatar around the 1720s. Their first settlement in Qatar was in the southern town of Sikak, and from there they moved north-west to Zubarah and Al Ruwais. They settled in Doha in the 19th century under their leader Mohammed bin Thani. The group was named after the father of Mohammad, Thani bin Mohammad. The family is made of four main factions: Bani Qassim, Bani Ahmed, Bani Jaber, and Bani Thamer. As of the early 1990s, the number of the family members was estimated to be about 20,000. The leadership transitions in 1913, 1949, 1960, and 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puducherry (union Territory)
Puducherry (), also known as Pondicherry () or Pondichéry, is a union territory of India, consisting of four small geographically unconnected districts. It was formed out of four territories of former French India, namely Pondichéry (Pondicherry; now Puducherry), Karikal (Karaikal), Mahé and Yanaon (now Yanam), excluding Chandannagar (Chandernagore), and it is named after the largest district, Puducherry, which was also the capital of French India. Historically known as Pondicherry (), the territory changed its official name to Puducherry on 20 September 2006. The Union Territory of Puducherry lies in the southern part of the Indian Peninsula. The areas of Puducherry district and Karaikal district are bound by the state of Tamil Nadu, while Yanam district and Mahé district are enclosed by the states of Andhra Pradesh and Kerala, respectively. Puducherry is the 29th most populous of the 36 states and union territories of India, and the third most densely populated ...

Mangroves
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of water ...

Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiosperm
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Pondicherry (city)
Pondicherry (), now known as Puducherry ( French: Pondichéry ʊdʊˈtʃɛɹi(listen), on-dicherry, is the capital and the most populous city of the Union Territory of Puducherry in India. The city is in the Puducherry district on the southeast coast of India and is surrounded by Bay of Bengal to the east and the state of Tamil Nadu, with which it shares most of its culture, heritage, and language. History Puducherry, formerly known as Pondicherry, gained its significance as “The French Riviera of the East” after the advent of the French colonialization in India. Puducherry is the Tamil interpretation of “new town” and mainly derived from “Poduke”, the name of the marketplace as the “Port town” for Roman trading in 1st century as mentioned in ‘The Periplus of the Erythraean Sea’. The settlement was once an abode of many learned scholars as evidently versed in the Vedas, hence also known as Vedapuri. The history of Puducherry can broadly be classified ...

École Française D'Extrême-Orient
The French School of the Far East (french: École française d'Extrême-Orient, ), abbreviated EFEO, is an associated college of PSL University dedicated to the study of Asian societies. It was founded in 1900 with headquarters in Hanoi in what was then French Indochina. After the independence of Vietnam, its headquarters were transferred to Phnom Penh in 1957 and subsequently to Paris in 1975. Its main fields of research are archaeology, philology and the study of modern Asian societies. Since 1907, the EFEO has been in charge of conservation work at the archeological site of Angkor. EFEO romanization system A romanization system for Mandarin was developed by the EFEO. It shares a few similarities with Wade-Giles and Hanyu Pinyin. In modern times, it has been superseded by Hanyu Pinyin. The differences between the three romanization systems are shown in the following table: Directors *1900: Louis Finot *1905: Alfred Foucher *1908: Claude-Eugène Maitre *1920: Louis ...

Borobudur
Borobudur, also transcribed Barabudur ( id, Candi Borobudur, jv, ꦕꦤ꧀ꦝꦶꦧꦫꦧꦸꦝꦸꦂ, Candhi Barabudhur) is a 9th-century Mahayana Buddhist temple in Magelang Regency, not far from the town of Muntilan, in Central Java, Indonesia. It is the world's largest Buddhist temple. The temple consists of nine stacked platforms, six square and three circular, topped by a central dome. It is decorated with 2,672 relief panels and originally 504 Buddha statues. The central dome is surrounded by 72 Buddha statues, each seated inside a perforated stupa. Built in the 9th century during the reign of the Sailendra Dynasty, the temple design follows Javanese Buddhist architecture, which blends the Indonesian indigenous tradition of ancestor worship and the Buddhist concept of attaining nirvāṇa. The temple demonstrates the influences of Gupta art that reflects India's influence on the region, yet there are enough indigenous scenes and elements incorporated to make Boro ...
