Cymbopogon Pendulus
''Cymbopogon'', also known as lemongrass, barbed wire grass, silky heads, Cochin grass, Malabar grass, oily heads, citronella grass or fever grass, is a genus of Asian, African, Australian, and tropical island plants in the grass family. Some species (particularly ''Cymbopogon citratus'') are commonly cultivated as culinary and medicinal herbs because of their scent, resembling that of lemons (''Citrus limon''). The name cymbopogon derives from the Greek words (, 'boat') and (, 'beard') "which mean hatin most species, the hairy spikelets project from boat-shaped spathes." Lemongrass and its oil are believed to possess therapeutic properties. Uses Citronella grass ('' Cymbopogon nardus'' and '' Cymbopogon winterianus'') grow to about and have magenta-colored base stems. These species are used for the production of citronella oil, which is used in soaps, as an insect repellent (especially mosquitoes and houseflies) in insect sprays and candles, and aromatherapy.

Cymbopogon Citratus
''Cymbopogon citratus'', commonly known as West Indian lemon grass or simply lemon grass, is a tropical plant native to Maritime Southeast Asia and introduced to many tropical regions. ''Cymbopogon citratus'' is often sold in stem form. While it can be grown in warmer temperate regions, such as the UK, it is not hardy to frost. Morphology ''Cymbopogon citratus'' is part of the grass family, Poaceae. They contain simple, bluish-green leaves with entire margins and are linear in shape. The blades tend to be 18–36 inches long. Like other grasses, the leaves also have parallel venation. Distribution ''Cymbopogon citratus'' is native to Island Southeast Asia (Malesia). It has been introduced extensively to South Asia since precolonial times. After the World War I, lemongrass was introduced to Madagascar, South America, and Central America. It has now been naturalized throughout the tropics and subtropics worldwide. In its native range, ''Cymbopogon citratus'' is known as ''se ...

Beekeeping
Beekeeping (or apiculture) is the maintenance of bee colonies, commonly in man-made beehives. Honey bees in the genus '' Apis'' are the most-commonly-kept species but other honey-producing bees such as ''Melipona'' stingless bees are also kept. Beekeepers (or apiarists) keep bees to collect honey and other products of the hive: beeswax, propolis, bee pollen, and royal jelly. Pollination of crops, raising queens, and production of package bees for sale are other sources of beekeeping income. Bee hives are kept in an apiary or "bee yard". The keeping of bees by humans, primarily for honey production, began around 10,000 years ago. Georgia is known as the "cradle of beekeeping" and the oldest honey ever found comes from that country. The 5,500-year-old honey was unearthed from the grave of a noblewoman during archaeological excavations in 2003 near the town Borjomi. Ceramic jars found in the grave contained several types of honey, including linden and flower honey. Domestication of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van Van Oil
A van is a type of road vehicle used for transporting goods or people. Depending on the type of van, it can be bigger or smaller than a pickup truck and SUV, and bigger than a common car. There is some varying in the scope of the word across the different English-speaking countries. The smallest vans, microvans, are used for transporting either goods or people in tiny quantities. Mini MPVs, compact MPVs, and MPVs are all small vans usually used for transporting people in small quantities. Larger vans with passenger seats are used for institutional purposes, such as transporting students. Larger vans with only front seats are often used for business purposes, to carry goods and equipment. Specially-equipped vans are used by television stations as mobile studios. Postal services and courier companies use large step vans to deliver packages. Word origin and usage Van meaning a type of vehicle arose as a contraction of the word caravan.

Hoodoo (folk Magic)
Hoodoo is a set of spiritual practices, traditions, and beliefs created and concealed from slaveholders by enslaved Africans in North America. Hoodoo evolved from various traditional African religions, practices, and in the American South incorporated with various elements of indigenous botanical knowledge. Hoodoo is an African Diaspora tradition created during the time of slavery in the United States and is an esoteric system of African-American occultism. Many of the practices are similar to other African Diaspora traditions as the practices come from the Bakongo people in Central Africa. Over the first century of the trans-Atlantic slave trade, an estimated 52% of all kidnapped Africans (over 900,000 people) came from Central African countries like Cameroon, Congo, Angola, Central African Republic and Gabon. By the end of the colonial period, enslaved Africans were taken from Angola (40 percent), Senegambia (19.5 percent), the Windward Coast (16.3 percent), and the Gold Coa ...

Erythropoiesis
Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. It is stimulated by decreased O2 in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin.Sherwood, L, Klansman, H, Yancey, P: ''Animal Physiology'', Brooks/Cole, Cengage Learning, 2005. This hormone stimulates proliferation and differentiation of red cell precursors, which activates increased erythropoiesis in the hemopoietic tissues, ultimately producing red blood cells (erythrocytes). In postnatal birds and mammals (including humans), this usually occurs within the red bone marrow. In the early fetus, erythropoiesis takes place in the mesodermal cells of the yolk sac. By the third or fourth month, erythropoiesis moves to the liver. After seven months, erythropoiesis occurs in the bone marrow. Increased levels of physical ac ...

Contact Dermatitis
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable. Contact dermatitis results from either exposure to allergens (allergic contact dermatitis), or irritants (irritant contact dermatitis). Allergic contact dermatitis involves a delayed type of hypersensitivity and previous exposure to an allergen to produce a reaction. Irritant contact dermatitis is the most common type and represents 80% of all cases. It is caused by prolonged exposure to irritants, leading to direct injury of the epidermal cells of the skin, which activates an immune response, resulting in an inflammatory cutaneous reaction. Phototoxic dermatitis occurs when the allergen or irritant is activated by sunlight. Diagnosis of allergic contact dermatitis can o ...

Maritime Southeast Asia
Maritime Southeast Asia comprises the countries of Brunei, Indonesia, Malaysia, the Philippines, Singapore, and East Timor. Maritime Southeast Asia is sometimes also referred to as Island Southeast Asia, Insular Southeast Asia or Oceanic Southeast Asia. The 16th-century term "East Indies" and the later 19th-century term " Malay Archipelago" are also used to refer to Maritime Southeast Asia. In Indonesia, the Old Javanese term "Nusantara" is also used as a synonym for Maritime Southeast Asia. The term, however, is nationalistic and has shifting boundaries. It usually only encompasses Peninsular Malaysia, the Sunda Islands, Maluku, and often Western New Guinea and excludes the Philippines. Stretching for several thousand kilometres, the area features a very large number of islands and boasts some of the richest marine, flora and fauna biodiversity on Earth. The main demographic difference that sets Maritime Southeast Asia apart from modern Mainland Southeast Asia is that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million.

European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burma
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: mjænmɑː, ˈbɜːmə So the pronunciation of the last syllable of Myanmar as ɑːror of Burma as ɜːrməby some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would be pronounced at the end by all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
