António Da Silva Porto
António Francisco Ferreira da Silva Porto (24 August 1817 – 2 April 1890) was a Portuguese trader and explorer in Angola, in the Portuguese West Africa. Biography Silva Porto was born to a poor family in Porto in continental Portugal; he was the son of humble parents, but whose father distinguished himself in battles against the French during their invasion in 1810. Instead of following his father into the military, the intelligent and ambitious boy looked to economic possibilities farther afield. Brazil was an obvious possibility, owing to the success of many emigrants; at the age of twelve, with his father's blessing, he emigrated to the Brazilian capital of Rio de Janeiro on board the brig ''Rio Ave''. After working for a while for a merchant he became indignant with his remuneration and quits, taking several itinerant jobs. At 18 years of age he landed in Bahia, where he made a point of announcing to the newspaper ''Correio Mercantil'' his new name, in order to rem ...

Portuguese West Africa
Portuguese Angola refers to Angola during the historic period when it was a territory under Portuguese rule in southwestern Africa. In the same context, it was known until 1951 as Portuguese West Africa (officially the State of West Africa). Initially ruling along the coast and engaging in military conflicts with the Kingdom of Kongo, in the 18th century Portugal gradually managed to colonise the interior Highlands. However, full control of the entire territory was not achieved until the beginning of the 20th century, when agreements with other European powers during the Scramble for Africa fixed the colony's interior borders. On 11 June 1951, the status was upgraded to Overseas Province of Angola and finally in 1973, State of Angola. In 1975, Portuguese Angola became the independent People's Republic of Angola. History The history of Portuguese presence on the territory of contemporary Angola lasted from the arrival of the explorer Diogo Cão in 1484 until the decolonization ...

Captain-major
A donatary captain was a Portuguese colonial official to whom the Crown granted jurisdiction, rights, and revenues over some colonial territory. The recipients of these grants were called (donataries), because they had been given the grant as a (donation) by the king, often as a reward for service.Johnson 1972 The term also applied as the rank title of the field officer that was in charge of a captaincy (group of companies) of the , the Portuguese territorial militia that existed from the 16th to the 19th centuries. Captaincy system Due to the impossibility of exercising direct control and sovereignty over overseas territories, the captain-major was the channel by which the monarch could delegate his powers, with certain restrictions, under the responsibility of peoples he felt he could confide. The could administer, in the sovereign's name, the lands for which he was assigned, with all the regalia, rights, and obligations, with the exception of certain limits, including milita ...

Portuguese-based Creole Languages
Portuguese creoles are creole languages which have Portuguese as their substantial lexifier. The most widely-spoken creoles influenced by Portuguese are Cape Verdean Creole, Guinea-Bissau Creole and Papiamento. Origins Portuguese overseas exploration in the 15th and 16th centuries led to the establishment of a Portuguese Empire with trading posts, forts and colonies in Africa, Asia and the Americas. Contact between the Portuguese language and native languages gave rise to many Portuguese-based pidgins, used as linguas francas throughout the Portuguese sphere of influence. In time, many of these pidgins were nativized, becoming new stable creole languages. As is the rule in most creoles, the lexicon of these languages can be traced to the parent languages, usually with predominance of Portuguese; These creoles are (or were) spoken mostly by communities of descendants of Portuguese, natives, and sometimes other peoples from the Portuguese colonial empire.

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Honey
Honey is a sweet and viscous substance made by several bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, as well as during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected from wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivory
Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. Besides natural ivory, ivory can also be produced synthetically, hence (unlike natural ivory) not requiring the retrieval of the material from animals. Tagua nuts can also be carved like ivory. The trade of finished goods of ivory products has its origins in the Indus Valley. Ivory is a main product that is seen in abundance and was used for trading in Harappan civilization. Finished ivory pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosives
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Textiles
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...
