Public
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the ''Öffentlichkeit'' or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, and suffered more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder. Etymology and definitions The name "public" originates with the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inorganic Chemistry
Inorganic chemistry deals with synthesis and behavior of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture. Key concepts Many inorganic compounds are ionic compounds, consisting of cations and anions joined by ionic bonding. Examples of salts (which are ionic compounds) are magnesium chloride MgCl2, which consists of magnesium cations Mg2+ and chloride anions Cl−; or sodium oxide Na2O, which consists of sodium cations Na+ and oxide anions O2−. In any salt, the proportions of the ions are such that the electric charges cancel out, so that the bulk compound is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sisal, Yucatán
Sisal () is a seaport town in Hunucmá Municipality in the state of Yucatán, Mexico. It was the principal port of Yucatán during the henequen boom, later overshadowed when the more modern port of Progreso was built to the east. It lent its name to the agave-derived sisal fiber which was shipped through this port. The town is about 53 km north north-west of Mérida, the state capital. By law when the Yucatán was part of New Spain, all commerce went through the port of Campeche. The residents of Mérida petititioned for a port closer to the capital, and this was granted by Spanish royal decree on 13 February 1810. The new port of Sisal was founded in 1811, and has a late colonial era fortress, the "Fuerte de Santiago", and an old lighthouse. After Yucatán's independence from Spain commerce in the port grew rapidly, and by 1845 was shipping cargos with twice the value that had previously gone through Campeche. After the development of Progreso, Sisal's importance decline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sisal Foreign Station
Sisal (, ) (''Agave sisalana'') is a species of flowering plant native to southern Mexico, but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making rope and various other products. The term sisal may refer either to the plant's common name or the fibre, depending on the context. The sisal fibre is traditionally used for rope and twine, and has many other uses, including paper, cloth, footwear, hats, bags, carpets, geotextiles, and dartboards. It is also used as fibre reinforcements for composite fibreglass, rubber, and concrete products. Taxonomy The native origin of ''Agave sisalana'' is uncertain. Traditionally, it was deemed to be a native of the Yucatán Peninsula, but no records exist of botanical collections from there. They were originally shipped from the Spanish colonial port of Sisal in Yucatán (thus the name). The Yucatán plantations now cultivate henequen (''Agave fourcroydes''). H.S. Gentry hypothesized a Chia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conjunto Externo De Tacuba
The term ''conjunto'' (, literally 'group', 'ensemble') refers to several types of small musical ensembles present in different Latin American musical traditions, mainly in Mexico and Cuba. While Mexican conjuntos play styles such as '' norteño'' and ''tejano'', Cuban ''conjuntos'' specialize in the ''son'', as well as its derivations such as ''salsa''. Mexican Mexican conjunto music, also known as ''conjunto tejano'', was born in south Texas at the end of the 19th century, after German settlers introduced the button accordion. The ''bajo sexto'' has come to accompany the button accordion and is integral to the ''conjunto'' sound. Many ''conjuntos'' are concentrated in the Southwestern portion of the United States, primarily in Texas and California. In Mexico, the term ''conjunto'' is associated with '' norteño'' and ''tejano'' music. Since ''tejano'' was bred out of ''norteño'' music originally, this association is not entirely false. However, due to various cultural and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Food Chemistry
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavors, and colors. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with microorganisms that convert lactose to lactic acid; an example of preventing a process would be stopping the browning on the surface of freshly cut apples using lemon juice or other acidulated water. History of food chemistry The scientific approach to food and nutrition arose with attention to agricultural chemistry in ...

Medicinal Chemistry
Medicinal or pharmaceutical chemistry is a scientific discipline at the intersection of chemistry and pharmacy involved with designing and developing pharmaceutical drugs. Medicinal chemistry involves the identification, synthesis and development of new chemical entities suitable for therapeutic use. It also includes the study of existing drugs, their biological properties, and their quantitative structure-activity relationships (QSAR). Medicinal chemistry is a highly interdisciplinary science combining organic chemistry with biochemistry, computational chemistry, pharmacology, molecular biology, statistics, and physical chemistry. Compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules (e.g., atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine), the latter of which are most often medicinal preparations of proteins (natural and recombinant ant ...
