Portuguese Inventions
The Portuguese inventions are the inventions created by the people born in Portugal (continent or overseas), or whose nationality is Portuguese. These inventions were created mainly during the age of Portuguese discoveries, and during modernity. Relying on trade secret explains, in part, the difficulty often experienced by researchers in documenting Portuguese inventions, as many are not described in patent documents, or other technical documents. On the other hand, there are cases, like some types of swords, where the inventions themselves or the underlying documents were lost, having been destroyed, for example, during the French invasions. There are as well documentation and objects of Portuguese origin in private collections or museums outside of Portugal. Discoveries The creation of new inventions in Portugal was at its peak during the Age of Discovery. These inventions consisted mainly in the improvement of devices and techniques of ocean navigation and coastal cartogra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carracks Black Sword
The Carracks black sword, sometimes called a crab sword, is a type of sword invented in Portugal, during the 15th century. It was used by Portuguese soldiers and sailors in ships and caravels in the Age of Discovery. Names *''Espada preta de bordo'' ("naval black sword") *''Espada carangueja'' or ''espada de caranguejo'' ("crab sword") Characteristics It is characterized by having a guard with two protective rings, with the guard terminals in the form of two flat drops pointing toward the tip of the blade, and forming large round plates sharpened sufficiently to be used as extra blades convenient in close combat. The protective rings, in addition to their function to guard the fingers, can also serve to trap an opponent's blade. These swords were painted black to prevent reflected light from betraying their presence on ships, as well as to mitigate corrosion caused by salt water. History This type of sword would have appeared between 1460 and 1480 in Portugal, culturally related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonius (device)
Nonius is a measuring tool used in navigation and astronomy named in honour of its inventor, Pedro Nunes (Latin: Petrus Nonius), a Portuguese author, mathematician and navigator. The nonius was created in 1542 as a system for taking finer measurements on circular instruments such as the astrolabe. The system was eventually adapted into the Vernier scale in 1631 by the French mathematician Pierre Vernier. Technical features The nonius was used to improve the astrolabe's accuracy. This consisted of a number of concentric circles traced on an instrument and dividing each successive one with one fewer divisions than the adjacent outer circle. On a standard scale of 90 degrees, there are an additional 44–45 concentric circles, with each divided into a specific unit size such that a scale unit on position n had an arc of 90/n degrees. Thus, the outermost quadrant would comprise 90° in 90 equal divisions, the next inner would have 89 divisions, the next 88 and so on. When an a ...

Square-rigged Caravel
The square-rigged caravel (), was a sailing ship created by the Portuguese in the second half of the fifteenth century. A much larger version of the caravel, its use was most notorious beginning in the end of that century. The square-rigged caravel held a notable role in the Portuguese expansion during the Age of Discovery, especially in the first half of the sixteenth century, for its exceptional maneuverability and combat capabilities. This ship was also sometimes adopted by other European powers. Its hull resembled the shape of the later galleon and some scholars have claimed that this vessel is a forerunner of the fighting galleon, by the name of . History The Portuguese square-rigged caravel or round caravel appeared more frequently in the end of the fifteenth century and the beginning of the sixteenth century. Traditionally considered a particular type of caravel but also a new and different type of ship due to its significant structural differences, it was the result of ...

Galleon
Galleons were large, multi-decked sailing ships developed in Spain and Portugal. They were first used as armed cargo carriers by Europe, Europeans from the 16th to 18th centuries during the Age of Sail, and they were the principal vessels drafted for use as Warship, warships until the Anglo-Dutch Wars of the mid-17th century. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were Carvel (boat building), carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and Mast (sailing), main-masts. Such ships played a major role in commerce in the sixteenth and seventeenth centuries and were often drafted into use as auxiliary naval war vessels—indeed, they were the mainstay of contending fleets through most of the 150 years of the Age of Exploration—before the Anglo-Dutch wars made purpose-built warships dominant at sea during the remainder of the Age of Sail.

Carrack
A carrack (; ; ) is a three- or four- masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe, most notably in Portugal and Spain. Evolving from the single-masted cog, the carrack was first used for European trade from the Mediterranean to the Baltic and quickly found use with the newly found wealth of the trade between Europe and Africa and then the trans-Atlantic trade with the Americas. In their most advanced forms, they were used by the Portuguese and Spaniards for trade between Europe, Africa and Asia starting in the late 15th century, before being gradually superseded in the late 16th and early 17th centuries by the galleon. In its most developed form, the carrack was a carvel-built ocean-going ship: large enough to be stable in heavy seas, and capacious enough to carry a large cargo and the provisions needed for very long voyages. The later carracks were square-rigged on the foremast and mainmast and lateen- rigged on the mizzenma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Commission
The European Commission (EC) is the primary Executive (government), executive arm of the European Union (EU). It operates as a cabinet government, with a number of European Commissioner, members of the Commission (directorial system, informally known as "commissioners") corresponding to two thirds of the number of Member state of the European Union, member states, unless the European Council, acting unanimously, decides to alter this number. The current number of commissioners is 27, including the president. It includes an administrative body of about 32,000 European civil servants. The commission is divided into departments known as Directorate-General, Directorates-General (DGs) that can be likened to departments or Ministry (government department), ministries each headed by a director-general who is responsible to a commissioner. Currently, there is one member per European Union member state, member state, but members are bound by their oath of office to represent the genera ...

Zebinix
Eslicarbazepine acetate (ESL), sold under the brand names Aptiom and Zebinix among others, is an anticonvulsant medication approved for use in Europe and the United States as monotherapy or as additional therapy for partial-onset seizures epilepsy. Similarly to oxcarbazepine, ESL behaves as a prodrug to (''S'')-(+)- licarbazepine. As such, their mechanisms of action are identical. Contraindications Eslicarbazepine acetate is contraindicated in people with second- or third-degree atrioventricular block, a type of heart block, in the Austria-Codex. However heart block is not mentioned as a contraindication by the US FDA. It is contraindicated for people who are hypersensitive to eslicarbazepine, oxcarbazepine or carbamazepine. Adverse effects Adverse effects are similar to oxcarbazepine. The most common ones (more than 10% of patients) are tiredness and dizziness. Other fairly common side effects (1 to 10%) include impaired coordination, gastrointestinal disorders such as diarrho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilepsy
Epilepsy is a group of Non-communicable disease, non-communicable Neurological disorder, neurological disorders characterized by a tendency for recurrent, unprovoked Seizure, seizures. A seizure is a sudden burst of abnormal electrical activity in the brain that can cause a variety of symptoms, ranging from brief lapses of awareness or muscle jerks to prolonged convulsions. These episodes can result in physical injuries, either directly, such as broken bones, or through causing accidents. The diagnosis of epilepsy typically requires at least two unprovoked seizures occurring more than 24 hours apart. In some cases, however, it may be diagnosed after a single unprovoked seizure if clinical evidence suggests a high risk of recurrence. Isolated seizures that occur without recurrence risk or are provoked by identifiable causes are not considered indicative of epilepsy. The underlying cause is often unknown, but epilepsy can result from brain injury, stroke, infections, Brain tumor, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Teller Machine
An automated teller machine (ATM) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance inquiries or account information inquiries, at any time and without the need for direct interaction with bank staff. ATMs are known by a variety of other names, including automatic teller machines (ATMs) in the United States (sometimes RAS syndrome, redundantly as "ATM machine"). In Canada, the term automated banking machine (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM rather than ABM. In British English, the terms cashpoint, cash machine and hole in the wall are also used. ATMs that are Independent ATM deployer, not operated by a financial institution are known as "White-label ABMs, white-label" ATMs. Using an ATM, customers can access their bank deposit or credit accounts in order to make ...
