Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bambusa Spinosa
''Bambusa'' is a large genus of clumping bamboos. Most species of ''Bambusa'' are rather large, with numerous branches emerging from the nodes, and one or two much larger than the rest. The branches can be as long as 11 m (35 ft). They are native to Southeast Asia, South Asia, China, Taiwan, the Himalayas, New Guinea, Melanesia, and the Northern Territory of Australia. They are also reportedly naturalized in other regions, e.g. Africa, Americas, and various oceanic islands.

Sulfuryl Fluoride
Sulfuryl fluoride (also spelled ''sulphuryl fluoride'') is an inorganic compound with the chemical formula, formula SO2F2. It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. It is neurotoxic and a potent greenhouse gas, but is widely used as a fumigant insecticide to control termites. Structure, preparation, reactions The molecule is tetrahedral with C2v symmetry point group, symmetry. The S-O distance is 140.5 pm, S-F is 153.0 pm. As predicted by VSEPR, the O-S-O angle is more open than the F-S-F angle, 124° and 97°, respectively. One synthesis begins with the preparation of potassium fluorosulfite: :SO2 + KF → KSO2F This salt is then chlorinated to give sulfuryl chloride fluoride: :KSO2F + Cl2 → SO2ClF + KCl Further heating at 180 °C of potassium fluorosulfite with the sulfuryl chloride fluoride gives the desired product: :SO2ClF + KSO2F → ...

Ozone Layer
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately above Earth, although its thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Measurements of the sun showed that the radiation sent out from its surface and reaching the ground on Earth is usually consistent with the spectrum of a black body with a temperature in the range of , except that there was no radiation below a wavelength of about 310 ...

Bromomethane
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It has a tetrahedral shape and it is a recognized ozone-depleting chemical. It was used extensively as a pesticide until being phased out by most countries in the early 2000s. Occurrence and manufacture Bromomethane originates from both natural and human sources. In the ocean, marine organisms are estimated to produce 56,000 tonnes annually. It is also produced in small quantities by certain terrestrial plants, such as members of the family Brassicaceae. It is manufactured for agricultural and industrial use by treating methanol with bromine in the presence of sulfur or hydrogen sulfide: :6 CH3OH + 3 Br2 + S → 6 CH3Br + 2 H2O + H2SO4 Uses In 1999, an estimated 71,500 tonnes of synthetic methyl bromide were used annually worldwide. 97% of this estimate was used for fumigation purposes, wh ...

Tectona Grandis
Teak (''Tectona grandis'') is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. ''Tectona grandis'' has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs ( perfect flowers). The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. ''Tectona grandis'' is native to south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring teak. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tectona
''Tectona'' is a genus of tropical hardwood trees in the mint family, ''Lamiaceae''.Heywood, V.H., Brummitt, R.K., Culham, A. & Seberg, O. 2007: Flowering Plant Families of the World. Royal Botanic Gardens, Kew. The three species are often collectively called teak. Description ''Tectona'' is native to south and southeast Asia, mainly India, Pakistan, Bangladesh, Myanmar, Indonesia and Thailand, and are commonly found as a component of monsoon forest vegetation. They are large trees, growing to 30–40 m (90–120 ft.) tall, deciduous in the dry season. ''Tectona grandis'' is an economically important species which is the source of most commercial teak wood products.

Spondias
''Spondias'' is a genus of flowering plants in the cashew family, Anacardiaceae. The genus consists of 17 described species, 7 of which are native to the Neotropics and about 10 are native to tropical Asia. They are commonly named hog plums, Spanish plums, libas in Bikol and in some cases golden apples for their brightly colored fruit which resemble an apple or small plum at a casual glance. They are only distantly related to apple and plum trees, however. A more unequivocal common name is mombins. A theory regarding the name of the city of Bangkok, Thailand is that the name is derived from th, -มะกอกน้ำ; 'water olive', the Thai name for the fruit of ''Spondias dulcis''. In Cambodia, ''Spondias pinnata'' is called /pɷːn siː pʰlaɛ/ (ពោនស៊ីផ្លែ) or /məkaʔ prẹj/ (ម្កាក់ព្រៃ), and ''Spondias dulcis'' simply /məkaʔ/ (ម្កាក់).

Shorea Robusta
''Shorea robusta'', the sal tree, sāla, shala, sakhua, or sarai, is a species of tree in the family Dipterocarpaceae. The tree is native to India, Bangladesh, Nepal, Tibet and across the Himalayan regions . Evolution Fossil evidence from lignite mines in the Indian states of Rajasthan and Gujarat indicate that sal trees (or at least a closely related ''Shorea'' species) have been a dominant tree species of forests of the Indian subcontinent since at least the early Eocene (roughly 49 million years ago), at a time when the region otherwise supported a very different biota from the modern day. Evidence comes from the numerous amber nodules in these rocks, which originate from the dammar resin produced by the sal trees. Description ''Shorea robusta'' can grow up to tall with a trunk diameter of . The leaves are 10–25 cm long and 5–15 cm broad. In wetter areas, sal is evergreen; in drier areas, it is dry-season deciduous, shedding most of the leaves from February t ...

Shorea
Fruit of a ''Shorea'' species ''Shorea'' is a genus of about 196 species of mainly rainforest trees in the family Dipterocarpaceae. The genus is named after Sir John Shore, the governor-general of the British East India Company, 1793–1798. The timber of trees of the genus is sold under the common names lauan, luan, lawaan, meranti, seraya, balau, bangkirai, and Philippine mahogany. Taxonomy ''Shorea'' fossils (linked with the modern sal, ''S. robusta'', which is still a dominant tree species in Indian forests) are known from as early as the Eocene of Gujarat, India. They are identifiable by the amber fossils formed by their Dammar gum, dammar resin. Other fossils include a Miocene-aged fossilized fruit from the same region; this fruit most closely resembles the extant ''Shorea macroptera, S. macroptera'' of the Malay Peninsula. Description ''Shorea'' spp. are native to Southeast Asia, from northern India to Malaysia, Indonesia, and the Philippines. In west Malesia and th ...

Pyrus Malus
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more th ...
