Os Lusíadas
''Os Lusíadas'' (), usually translated as ''The Lusiads'', is a Portuguese epic poem written by Luís Vaz de Camões ( – 1580) and first published in 1572. It is widely regarded as the most important work of Portuguese-language literature and is frequently compared to Virgil's ''Aeneid'' (1st c. BC). The work celebrates the discovery of a sea route to India by the Portuguese explorer Vasco da Gama (1469–1524). The ten cantos of the poem are in ottava rima and total 1,102 stanzas. Written in Homeric fashion, the poem focuses mainly on a fantastic interpretation of the Portuguese voyages of discovery during the 15th and 16th centuries. ''Os Lusíadas'' is often regarded as Portugal's national epic, much as Virgil's ''Aeneid'' was for the Ancient Romans, or Homer's ''Iliad'' and ''Odyssey'' for the Ancient Greeks. It was written when Camões was an exile in Macau and was first printed in 1572, three years after the author returned from the Indies. Internal structure The poe ...

Military Supply
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Force Academies
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Higher Education In Portugal
Higher education in Portugal is divided into two main subsystems: university and polytechnic education. It is provided in autonomous public and private universities, university institutes, polytechnic institutes and higher education institutions of other types. The higher education institutions of Portugal grant the licentiate, master's and doctoral academic degrees, with the last one being reserved to be granted only by the university institutions. Higher education in state-run educational establishments is provided on a competitive basis, a system of ''numerus clausus'' is enforced through a national database on student admissions. In addition, every higher education institution offers also a number of additional vacant places through other extraordinary admission processes for sportsmen, mature applicants (over 23 years old), international students, foreign students from the Lusosphere, degree owners from other institutions, students from other institutions (academic trans ...

Asas De Portugal
The () was a flight demonstration team created in 1977 integrated with ''Esquadra'' 103 (103 Squadron) of the Portuguese Air Force. It was Portugal's national aerobatic flying team and flew two ex-German Air Force Dassault-Breguet/Dornier Alpha Jets. History In 1977, Asas de Portugal was created by order of the Air Force Chief of Staff (CEMFA), with the objective to represent the Portuguese Air Force (PoAF) at the International Air Tattoo air festival. This was the third aerobatics team established by the PoAF, after two teams of the 1950s — the '' Dragões'' (Dragons) and the ''São Jorge'' (Saint George) teams. Asas de Portugal operated the Cessna T-37C for 13 years while integrated with the 102 Squadron ''Panchos''. The single fatal accident in the team's history occurred on 9 December 1990, when one of its T-37Cs suffered a catastrophic wing structural failure during a practice session, killing team pilot José Magalhães da Costa. The accident prompted a fleet-wide in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marquis Of Pombal
Count of Oeiras () was a Portuguese title of nobility created by a royal decree, dated July 15, 1759, by King Joseph I of Portugal, and granted to Sebastião José de Carvalho e Melo, head of the Portuguese government.

Portuguese Naval School
The Naval School ( pt, Escola Naval) is a higher education level naval academy in Alfeite, Portugal. The Naval School is located in the Lisbon Naval Base premises, located on the south bank of the Tagus river, in front of the city of Lisbon. The school offers university and polytechnical graduate programmes intended to train the future officers of the Portuguese Navy. It also offers postgraduate programmes, these being open to civilians, as well to naval and other military personnel. History The present Portuguese Naval School was created in the 18th century as the Royal Academy of the Midshipmen (''Academia Real dos Guardas-Marinhas''). In 1782, the Company of Midshipmen (''Companhia dos Guardas-Marinhas'') was created to frame and train the midshipmen (naval officer candidates) of the Portuguese Navy. The Company of Midshipmen was installed in the building of the Naval Arsenal of Lisbon. The Royal Academy of the Midshipmen was created in 1792, as a university-level naval a ...

Portuguese Armed Forces
The Portuguese Armed Forces ( pt, Forças Armadas) are the military of Portugal. They include the General Staff of the Armed Forces, the other unified bodies and the three service branches: Portuguese Navy, Portuguese Army and Portuguese Air Force. The President of the Republic is the head of the Portuguese military, with the title of " Supreme Commander of the Armed Forces" (''Comandante Supremo das Forças Armadas''). The management of the Armed Forces and the execution of the national defense policy is however done by the government (chaired by the Prime Minister) via its Minister of National Defense. The highest-ranking officer in the military is the Chief of the General Staff of the Armed Forces, which has operational control of the Armed Forces during peacetime and assumes their full control when a state of war exists. The Armed Forces are charged with protecting Portugal as well as supporting international peacekeeping efforts when mandated by the North Atlantic Treaty ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Early Warning Radar
An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as ''early'' as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate. This contrasts with systems used primarily for tracking or gun laying, which tend to offer shorter ranges but offer much higher accuracy. EW radars tend to share a number of design features that improve their performance in the role. For instance, EW radar typically operates at lower frequencies, and thus longer wavelengths, than other types. This greatly reduces their interaction with rain and snow in the air, and therefore improves their performance in the long-range role where their coverage area will often include precipitation. This also has the side-effect of lowering their optical resolution, but this is not important in this role. Likewise, EW radars often use much lower pulse repetition frequency to maximi ...

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
