Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical study.
Organic farming, also known as organic agriculture or ecological farming or biological farming, is an agricultural system that emphasizes the use of naturally occurring, non-synthetic inputs such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation, companion planting, and mixed cropping. Biological pest control methods such as the fostering of insect predators are also encouraged. Organic agriculture can be defined as "an integrated farming system that strives for sustainability, the enhancement of soil fertility and biological diversity while, with rare exceptions, prohibiting synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones". It originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture today accounts for 70 million hectares globally, with over half of that total in Australia.
Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, with the rearing of worms for this purpose is called vermiculture.
Organic reactions are chemical reactions involving organic compounds. The basic organic chemistry reaction types are addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions, photochemical reactions and redox reactions. In organic synthesis, organic reactions are used in the construction of new organic molecules. The production of many man-made chemicals such as drugs, plastics, food additives, fabrics depend on organic reactions.
A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawn mower and used for aesthetic and recreational purposes—it is also commonly referred to as part of a garden. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color, and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, parade, pitch, field or green may be used, depending on the sport and the continent.
Vegan organicagriculture is the organic production of food and other crops with minimal animal inputs. Vegan organic agriculture is the organic form of animal-free agriculture.
The organic movement broadly refers to the organizations and individuals involved worldwide in the promotion of organic food and other organic products. It started during the first half of the 20th century, when modern large-scale agricultural practices began to appear.
A house church or home church is a label used to describe a group of Christians who regularly gather for worship in private homes. The group may be part of a larger Christian body, such as a parish, but some have been independent groups that see the house church as the primary form of Christian community.
A protein skimmer or foam fractionator is a device used to remove organic compounds such as food and waste particles from water. It is most commonly used in commercial applications like municipal water treatment facilities, public aquariums, and aquaculture facilities. Smaller protein skimmers are also used for filtration of home saltwater aquariums and even freshwater aquariums and ponds.
Seed companies produce and sell seeds for flowers, fruits and vegetables to commercial growers and amateur gardeners. The production of seed is a multibillion-dollar global business, which uses growing facilities and growing locations worldwide. While most of the seed is produced by large specialist growers, large amounts are also produced by small growers who produce only one to a few crop types. The larger companies supply seed both to commercial resellers and wholesalers. The resellers and wholesalers sell to vegetable and fruit growers, and to companies who package seed into packets and sell them on to the amateur gardener.
Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem.
In chemistry, a counterion is the ion that accompanies an ionic species in order to maintain electric neutrality. In table salt the sodium ion is the counterion for the chloride ion and vice versa.
A health food store is a type of grocery store that primarily sells healthful foods, organic foods, local produce, and often nutritional supplements. Health food stores typically offer a wider or more specialized selection of foods than conventional grocery stores for their customers, for example people with special dietary needs, such as people who are allergic to the gluten in wheat or some other substance, and for people who observe vegetarian, vegan, raw food, organic, or other alternative diets.
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. It is a practice that encompasses the art of maintaining one's own aquatic ecosystem, featuring a lot of variety with various water systems, all of which have their own unique features and requirements. Fishkeeping primarily serves as a token of appreciation and fascination for marine life and the environment that surrounds such, along with other purposes such as the piscicultural fishkeeping industry, serving as a branch of agriculture, being one of the most widespread methods of cultivating fish for commercial profit.
Major (Maj) is a military rank which is used by both the British Army and Royal Marines. The rank is superior to captain and subordinate to lieutenant colonel. The insignia for a major is a crown. The equivalent rank in the Royal Navy is lieutenant commander, and squadron leader in the Royal Air Force.
Glycine encephalopathy is a rare autosomal recessive disorder of glycine metabolism. After phenylketonuria, glycine encephalopathy is the second most common disorder of amino acid metabolism. The disease is caused by defects in the glycine cleavage system, an enzyme responsible for glycine catabolism. There are several forms of the disease, with varying severity of symptoms and time of onset. The symptoms are exclusively neurological in nature, and clinically this disorder is characterized by abnormally high levels of the amino acid glycine in bodily fluids and tissues, especially the cerebrospinal fluid.
A regimental combat team (RCT) is a provisional major infantry unit which has seen use by branches of the United States Armed Forces. It is formed by augmenting a regular infantry regiment with smaller combat, combat support and combat service support units.
Pochvennichestvo was a late 19th-century movement in Russia that tied in closely with its contemporary ideology, Slavophilia.
Organic unity is the idea that a thing is made up of interdependent parts. For example, a body is made up of its constituent organs, and a society is made up of its constituent social roles. In Aristotle's Poetics he likened drama narrative's and action to organic form, presenting it as “a complete whole, with its several incidents so closely connected that the transposal or withdrawal of any one of them will disjoin and dislocate the whole.” The main theme of organic unity relies on a free-spirited style of writing and by following any guidelines or genre-based habits, the true nature of a work becomes stifled and unreliable on an artistic plane. The concept of organic unity gained popularity through the New Critics movement. Cleanth Brooks played an integral role in modernizing the organic unity principle. In The Well Wrought Urn, Brooks used the poem "The Canonization" by John Donne as an example to relate the importance of a work’s ability to flow and maintain a theme, so that the work gains momentum from beginning to end. Organic unity is the common thread that keeps a theme from becoming broken and disjointed as a work moves forward.
The (common) bond of association or common bond is the social connection among the members of credit unions and co-operative banks. Common bonds substitute for collateral in the early stages of financial system development. Like solidarity lending, the common bond has since played an important role in facilitating the development of microfinance for poor people.
