Mira

Mira (/ˈmaɪrə/, also known as Omicron Ceti, ο Ceti, ο Cet) is a red giant star estimated 200–400 light years away in the constellation Cetus. Mira is a binary star, consisting of the red giant Mira A along with Mira B. Mira A is also an oscillating variable star and was the first non-supernova variable star discovered, with the possible exception of Algol. Mira is the brightest periodic variable in the sky that is not visible to the naked eye for part of its cycle. Its distance is uncertain; pre-Hipparcos estimates centered on 220 light-years; while Hipparcos data from the 2007 reduction suggest a distance of 299 light-years, with a margin of error of 11%.

Observation history

Evidence that the variability of Mira was known in ancient China, Babylon or Greece is at best only circumstantial. What is certain is that the variability of Mira was recorded by the astronomer David Fabricius beginning on August 3, 1596. Observing what he thought was the planet Mercury (later identified as Jupiter), he needed a reference star for comparing positions and picked a previously unremarked third-magnitude star nearby. By August 21, however, it had increased in brightness by one magnitude, then by October had faded from view. Fabricius assumed it was a nova, but then saw it again on February 16, 1609.

Miraí

Miraí is a Brazilian municipality located in the state of Minas Gerais. The city belongs to the mesoregion of Zona da Mata and to the microregion of Muriaé.

History

Brejo was its first name. The agriculture sector is pointed as one of the most successful of the region Zona da Mata. The city territory is located in a region of easy access due to the presence of Rio-Bahia highway, also called BR-116. The first village was set up on the margins of the Muriaé River. Around 1840, attracted by land fertility, the first explorers came to Miraí's region. Finding land and good water, they spread the news and eventually other farmers arrived. At 1852, a group of farmers acquired part of the land belonging to the farm named Três Barras, in the place they built a chapel to Santo Antônio and around grew a village called Brejo. Later, the village became the District of Paz, with the name of Santo Antônio do Muriaé, belonging to Freguesia de Santa Rita de Meia Pataca. At 1883, the district was turned into Freguesia de Santo Antônio do Camapuã. The name was changed to Miraí, which means "wet land" in Tupi, by 1895. The municipality was created in 1923, separating itself from Cataguases.

Mira (film)

Mira is a 1971 Dutch-Belgian drama film directed by Fons Rademakers. It was entered into the 1971 Cannes Film Festival. The film was selected as the Dutch entry for the Best Foreign Language Film at the 44th Academy Awards, but was not accepted as a nominee.

KaiA

kaiA is a gene in the "kaiABC" gene cluster that plays a crucial role in the regulation of circadian rhythm in bacteria, such as the cyanobacterium Synechococcus elongatus. For these bacteria, regulation of kaiA expression is critical for circadian rhythm, which determines the twenty-four hour biological rhythm. In addition, KaiA functions with a negative feedback loop in relation with kaiB and KaiC. The kaiA gene makes KaiA protein that enhances phosphorylation of KaiC while KaiB inhibits activity of KaiA.

History

Discovery

Circadian rhythms have been discovered in a diversity of organisms. These rhythms control a variety of physiological activities and adapt to environmental conditions. Cyanobacteria are the most primitive organisms that demonstrate a circadian oscillation. Cyanobacteria clocks were first founded in Blue Green Algae with the oldest known fossils about 3.5 billion years old. Susan Golden, Carl Johnson and Takao Kondo were the individuals who found that the minimal cyanobacteria clock consists of 3 proteins: KaiA, KaiB, and KaiC. (Note: kai means cycle in Japanese.) The experiment performed by Kondo consisted of attaching the luciferase gene and performing mutagenesis. This was the first identification of possible genes that could reconstitute a biological clock within cyanobacteria, of which KaiA was included.

Air 1

Air1 is a contemporary hit radio (CHR) Christian radio network in the United States, playing Contemporary Christian music. It is operated by the non-profit Educational Media Foundation and is syndicated on dozens of stations across 42 states in cities including San Bernardino, San Diego, Houston, Dallas-Fort Worth, Seattle-Tacoma, Portland, Phoenix, Oklahoma City, Tulsa, Ventura, Thousand Oaks, Kansas City, Virginia Beach-Norfolk, Burlington, Jacksonville and portions of Los Angeles.

History

In 1986, KLRD began broadcasting Christian music from Yucaipa, California, and went by the on-air moniker K-LORD. In 1994, KXRD was started as a sister station to KLRD. In 1995, K-LORD changed their name to "Air 1" and began broadcasting via satellite from St. Helens, Oregon. In 1999, Air 1 joined with EMF Broadcasting (the former name of KLA1 Foundation), and finally in 2002, it moved its headquarters to Rocklin, California. Air 1 makes use of broadcast translators to spread the signal across much of the country. As of November 2011, the network lists 90 full powered radio stations and 125 translators of various power levels reaching 40 states.
