Ortho Pharmaceutical
Ortho Pharmaceutical was initially formed in the United States in 1931 as a subsidiary of Johnson & Johnson to market the first prescription spermicidal contraceptive jelly, ''Ortho-Gynol''. History In the 1940s, Ortho introduced the coil-spring diaphragm, and assisted in the development of the Papanicolaou smear stain to screen for cervical cancer. In 1963, Ortho introduced the second oral contraceptive available in the United States (''Ortho-Novum 10'' and ''Ortho-Novum 2'', produced by Syntex).In 1964, Ortho bought rights to and marketed the ''Gynekoil'' (Margulies Coil) and ''Lippes Loop'' inert plastic IUDs in the United States until the mid-1970s and 1985, respectively.In 1968, Ortho introduced '' RhoGAM Rho(D) immune globulin'', the first medication developed to prevent Rh hemolytic disease of the newborn. In 1973, Ortho and Syntex introduced the first progestogen only pills (mini-pills) available in the United States, ''Mirconor'' and ''Nor-QD''. In 1982, Ortho in ...

Ortho-DOT
Ortho-DOT, or 4,5-dimethoxy-2-methylthioamphetamine, is a lesser-known psychedelic drug. Ortho-DOT was first synthesized by Alexander Shulgin. In his book '' PiHKAL (Phenethylamines i Have Known And Loved)'', neither the dosage nor the duration are known. Ortho-DOT produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of Ortho-DOT.

Arene Substitution Patterns
Arene substitution patterns are part of organic chemistry IUPAC nomenclature and pinpoint the position of substituents other than hydrogen in relation to each other on an aromatic hydrocarbon. ''Ortho'', ''meta'', and ''para'' substitution * In ''ortho''-substitution, two substituents occupy positions next to each other, which may be numbered 1 and 2. In the diagram, these positions are marked R and ''ortho''. * In ''meta''-substitution the substituents occupy positions 1 and 3 (corresponding to R and ''meta'' in the diagram). * In ''para''-substitution, the substituents occupy the opposite ends (positions 1 and 4, corresponding to R and ''para'' in the diagram). The toluidines serve as an example for these three types of substitution. Synthesis Electron donating groups, for example amino, hydroxyl, alkyl, and phenyl groups tend to be ''ortho''/''para''-directors, and electron withdrawing groups such as nitro, nitrile, and ketone groups, tend to be ''meta''-directors.

Orthopraxy
In the study of religion, orthopraxy is correct conduct, both ethical and liturgical, as opposed to faith or grace. Orthopraxy is in contrast with orthodoxy, which emphasizes correct belief. The word is a neoclassical compound— () meaning 'right practice'. While orthodoxies make use of codified beliefs, in the form of creeds, and ritualism more narrowly centers on the strict adherence to prescribed rites or rituals, orthopraxy is focused on issues of family, cultural integrity, the transmission of tradition, sacrificial offerings, concerns of purity, ethical system, and the enforcement thereof. In Hinduism, orthopraxy and ritualism are often interconnected. Judaism and Christianity are also considered both religions and orthopraxies, as they guide adherents in both practice and belief. Biale, David, ''Not in the Heavens: The Tradition of Jewish Secular Thought'', Princeton University Press, 2011, p.15 Etymology The term ''orthopraxy'' comes from the Greek , meaning " ...

Orthochromatic
In chemistry, orthochromasia is the property of a dye or stain to not change color on binding to a target, as opposed to metachromatic stains, which change color. The word is derived from the Greek '' orthos'' (correct, upright), and chromatic (color). Toluidine blue is an example of a partially orthochromatic dye, as it stains nucleic acids by its orthochromatic color (blue), but stains mast cell granules in its metachromatic color (red). In spectral terms, orthochromasia refers to maintaining the position of spectral peaks, while metachromasia refers to a shift in wavelength, becoming either shorter or longer. In photography, an orthochromatic light spectrum is one devoid of red light. In biology, orthochromatic refers to the greyish staining because of acidophilic and basophilic mixture in the cell. Orthochromatic photography Orthochromatic photography refers to a photographic emulsion that is sensitive to only blue and green light, and thus can be processed with a red ...

Ortho Mode Transducer
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a ''polarisation duplexer''. ''Orthomode'' is a contraction of ''orthoganal mode''. Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. One of the paths forms the uplink, which is transmitted over the same waveguide as the received signal path, or downlink path. Such a device may be part of a very small aperture terminal (VSAT) antenna feed or a terrestrial microwave radio feed; for example, OMTs are often used with a feed horn to isolate orthogonal polarizations of a signal and to transfer transmit and receive signals to different ports. VSAT and satellite Earth station applications For VSAT modems the transmission and reception paths are at 90° to each other, or in other words, the signals are orthogonally polarized with respect to each other. This orthogonal shift between the two signal paths provides approximately an isola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotts Miracle-Gro Company
The Scotts Miracle-Gro Company is an American multinational corporation headquartered in Marysville, Ohio, where O.M. Scott began selling lawn seed in 1868. The company manufactures and sells consumer lawn, garden and pest control products, and soilless indoor gardening equipment. In the U.S., the company manufactures Scotts, Miracle-Gro and Ortho brands. The company also markets consumer Roundup. In 2021, despite billions of dollars in awards to Roundup's victims and their next-of-kin, ''Scotts Miracle-Gro'' was supportive of their marketing arrangement. History Scotts was founded in 1868 by Orlando M. Scott as a premium seed company for the U.S. agricultural industry. In the early 1900s, the company began a lawn grass seed business for homeowners, and in 1924, became the first company to ship grass seed products directly to stores. Prior to 1924, Scotts products were only available through the mail. By 1940, Scotts's sales had reached $1,000,000 and the company had 66 asso ...

Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or a ...

Lawn Care
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 lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color (e.g., by watering), 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, pitch, field or green may be used, depending on the sport and the continent. The term "lawn", referring to a managed grass space, dates to at least than the 16th century. With suburban expansion, the lawn has become culturally ingrained in some areas of the world as part of the desired household aesthetic.Robbins, PaulLawn People: How Grasses, Weeds, and Chemicals Make Us Who We Are P ...
