Breathing

Breathing is the process that moves air in and out of the lungs, or oxygen through other respiratory organs such as gills. For organisms with lungs, breathing is also called ventilation, which includes both inhalation and exhalation. Breathing is one part of physiological respiration required to sustain life.Aerobic organisms of birds, mammals, and reptiles—require oxygen to release energy via cellular respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one of the processes that deliver oxygen to where it is needed in the body and remove carbon dioxide. Another important process involves the movement of blood by the circulatory system.Gas exchange occurs in the pulmonary alveoli by passive diffusion of gases between the alveolar gas and the blood in lung capillaries. Once these dissolved gases are in the blood, the heart powers their flow around the body (via the circulatory system). The medical term for normal relaxed breathing is eupnea.

Breath (Breaking Benjamin song)

"Breath" is the second single and the third track from post-grunge/alternative metal band Breaking Benjamin's third album, Phobia. It was the band's fourth charted song on the U.S. Hot 100 overall, and the second from Phobia. Although "Breath" failed to capture the pop success of The Diary of Jane at #50 where "Breath" hit #84 on the Billboard Hot 100, it was more successful on the rock charts where it hit #1 on the US Mainstream Rock Tracks chart, making it Breaking Benjamin's first number-one hit staying there for seven weeks where "The Diary of Jane" hit #2 and it also hit #3 on the US Modern Rock Tracks chart tying with So Cold as their highest-charting single on the chart where "The Diary of Jane" hit #4.

A contest was held in which fans create a music video for "Breath", called the Breath Fan Video Contest, and the band and label selected 4 videos as finalists. The winning video was officially released March 30, 2008 on YouTube. The video can also be seen at the band's official site. The single was eventually certified platinum by the RIAA in 2015.

Velocity (software development)

Velocity is a capacity planning tool sometimes used in Agile software development. Velocity tracking is the act of measuring said velocity. The velocity is calculated by counting the number of units of work completed in a certain interval, the length of which is determined at the start of the project.

Principle

The main idea behind velocity is to help teams estimate how much work they can complete in a given time period based on how quickly similar work was previously completed.

Terminology

The following terminology is used in velocity tracking.

Usage

To calculate velocity, a team first has to determine how many units of work each task is worth and the length of each interval. During development, the team has to keep track of completed tasks and, at the end of the interval, count the number of units of work completed during the interval. The team then writes down the calculated velocity in a chart or on a graph.

The first week provides little value, but is essential to provide a basis for comparison. Each week after that, the velocity tracking will provide better information as the team provides better estimates and becomes more used to the methodology.

Velocity (TV channel)

Velocity (formerly HD Theater and originally Discovery HD Theater) is an American high-definition, commercial-based, cable and satellite television channel owned by Discovery Communications. The channel specializes in nonfictional programming, focusing on cars, sports related shows, and other programming targeted at men ages 18–54.

As of February 2015, approximately 62.3 million American households (53.5% of households with television) receive Velocity.

History

The channel launched nationwide in the United States on June 17, 2002, as Discovery HD Theater. The channel was rebranded to HD Theater on September 22, 2007, because Discovery Communications launched HD simulcasts of some of its other channels including Animal Planet, Discovery Channel, Science and TLC.

On April 14, 2011, Discovery Communications announced that HD Theater would be re-launched as Velocity later in the year: aimed primarily at an "upscale male" audience, the network focuses primarily on automotive-oriented programming and other shows of interest to a male audience. The re-launch took place on October 4, 2011.
