Varig
VARIG (acronym for Viação Aérea RIo-Grandense, ''Rio Grandean Airways'') was the first airline founded in Brazil, in 1927. From 1965 until 1990, it was Brazil's leading airline, and virtually its only international one. In 2005, Varig went into judicial restructuring, and in 2006 it was split into two companies – Flex Linhas Aéreas, informally known as "old" Varig, heir to the original airline – now defunct, and "new" Varig, a new company, fully integrated into Gol Airlines. History Formation and Early Years (1927–1943) ''Sociedade Anônima Empresa de Viação Aérea Rio-Grandense – VARIG'' was the first national airline established in Brazil. It was founded on 7 May 1927 in Porto Alegre, by Otto Ernst Meyer-Labastille, a German aviator decorated in the World War I, who immigrated to Brazil in 1921 and noticed how necessary air transportation was for a large country like Brazil. Varig was an off-spring of the German trade company and airline Condor Syndikat, thus sh ...

Ventral Respiratory Group
The respiratory center is located in the medulla oblongata and pons, in the brainstem. The respiratory center is made up of three major respiratory groups of neurons, two in the medulla and one in the pons. In the medulla they are the dorsal respiratory group, and the ventral respiratory group. In the pons, the pontine respiratory group includes two areas known as the pneumotaxic centre and the apneustic centre. The respiratory centre is responsible for generating and maintaining the rhythm of respiration, and also of adjusting this in homeostatic response to physiological changes. The respiratory center receives input from chemoreceptors, mechanoreceptors, the cerebral cortex, and the hypothalamus in order to regulate the rate and depth of breathing. Input is stimulated by altered levels of oxygen, carbon dioxide, and blood pH, by hormonal changes relating to stress and anxiety from the hypothalamus, and also by signals from the cerebral cortex to give a conscious control of r ...

Viktor Rydberg Gymnasium
Viktor Rydberg Gymnasium (VRG) is a group of four gymnasium (upper secondary schools) in Stockholm, Sweden named after the famous Swedish author Viktor Rydberg. The four upper secondary schools are VRG Djursholm, VRG Odenplan, VRG Jarlaplan and VRG Sundbyberg, run by the Viktor Rydberg Schools Foundation. The foundation also runs three secondary schools, Viktor Rydbergs samskola Djursholm, Viktor Rydbergs skola Vasastan, and Viktor Rydbergs skola Sundbyberg. Members of its board of directors are currently Louise Ankarcrona, Louise Westerberg, Fredrik Palmstierna, Stefan Persson, Fanny Falkenberg, Nils Andersson, Thomas Hvid and Sofia Bendz.

The schools have students attending from all over the greater Stockholm region, making admission highly competitive. VRG Odenplan has some of the hig ...

Vintage Racer Group
Vintage, in winemaking, is the process of picking grapes and creating the finished product—wine (see Harvest (wine)). A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though not strictly correct, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality. Most countries allow a vintage wine to include a portion of wine that is not from the year denoted on the label. In Chile and South Africa, the requirement is 75% same-year content for vintage-dated wine. In Australia, New Zealand, and the member states of the European Union, the requirement is 85%. In the United States, the requirement is 85%, unless the wine is designated with an AVA, (e.g., Napa Valley), in which case it is 95%. Technically, the 85% r ...
