Tropical Storm Zeta

Tropical Storm Zeta was a late-developing tropical storm over the central Atlantic that formed after the 2005 Atlantic hurricane season had officially ended (on November 30) and continued into January 2006. Becoming a tropical depression at approximately midnight on December 30 (UTC), it became the record-breaking thirtieth tropical cyclone of the 2005 Atlantic hurricane season and after intensifying into Tropical Storm Zeta six hours later, it become the season's twenty-seventh named storm. Zeta was one of only two Atlantic tropical cyclones to span two calendar years (the other being Hurricane Alice in 1954–55).

Zeta originated from an area of low pressure on December 29, which previously developed within an upper-level trough. After becoming a tropical storm, the National Hurricane Center continually predicted it would weaken rapidly. Like the previous tropical cyclone, Hurricane Epsilon, Zeta defied these predictions. The storm reached its peak strength on January 2, 2006 before finally dissipating on January 6. As Zeta never approached land there was no impact from the storm other than minor shipping problems. Several ships encountered the storm, and several crews in the 2005 Atlantic Rowing Race were affected by rough seas and high winds.

Zeta (wasp)

Zeta is a small neotropical genus of potter wasps currently containing 4 species. Three of them have restricted distributions: Zeta confusum is found only in Cuba; Zeta abdominalis is spread through several caribbean islands (Jamaica, Hispaniola, Puerto Rico, Virgin Islands and Antigua, with three presently recognized subspecies) and Zeta mendozanum is restricted to the Monte and Patagonia regions of Argentina. Zeta argillaceum, on the other hand, is a very common, widespread and variable species found in the continental Americas from the southern United States (where it was probably introduced) to central Argentina. The wide range of color variation of this species has led to the recognition of a number of subspecies and varieties currently treated as simple synonyms.

YWHAZ

14-3-3 protein zeta/delta (14-3-3ζ) is a protein that in humans is encoded by the YWHAZ gene on chromosome 8. The protein encoded by this gene is a member of the 14-3-3 protein family and a central hub protein for many signal transduction pathways. 14-3-3ζ is a major regulator of apoptotic pathways critical to cell survival and plays a key role in a number of cancers and neurodegenerative diseases.

Structure

14-3-3 proteins generally form ~30 kDa-long homo- or heterodimers. Each of the monomers are composed of 9 antiparallel alpha helices. Four alpha-helices (αC, αE, αG, and αI) form an amphipathic groove that serves as the ligand binding site, which can recognize three types of consensus binding motifs: RXX(pS/pT)XP, RXXX(pS/pT)XP, and (pS/pT)X1-2-COOH (where pS/pT represents phosphorylated serine/threonine). In addition to these primary interactions, the target protein can also bind outside the groove via secondary interactions. In particular, the crystallized structure of 14-3-3ζ forms a cup-shaped dimer when complexed with CBY. The YWHAZ gene encodes two transcript variants which differ in the 5' UTR but produce the same protein.

Chain (unit)

A chain (ch) is a unit of length. It measures 66 feet, or 22 yards, or 100 links, or 4 rods (20.1168 m). There are 10 chains in a furlong, and 80 chains in one statute mile. An acre is the area of 10 square chains (that is, an area of one chain by one furlong). The chain has been used for several centuries in Britain and in some other countries influenced by British practice.

By extension, chainage (running distance) is the distance along a curved or straight survey line from a fixed commencing point, as given by an odometer.

Origin

The chain was commonly used with the mile to indicate land distances and in particular in surveying land for legal and commercial purposes. Starting in the 19th centary, the chain was used as a sub division with the mile to show distances between railway stations, tunnels and bridges. In medieval times, local measures were commonly used, and many units were adopted that gave manageable units; for example the distance from London to York could be quoted in inches, but the resulting huge number would be unmemorable. The locally used units were often inconsistent from place to place.

Chain (Paul Haig album)

Chain was Edinburgh musician Paul Haig's third album and was released in May 1989 on Circa Records, a subsidiary of Virgin Records. Chain, which Haig financed himself, was recorded and completed in 1988, but it sat on the shelf after the normally accommodating Les Disques Du Crepuscule decided not to take up the option of releasing it. The album was co-produced by long-time Haig cohort, Alan Rankine, instrumentalist with celebrated Dundee band, The Associates. There was another Associates connection on the album - the track "Chained" was written by Haig's good friend, Billy Mackenzie. Haig returned the favour and gave Mackenzie the track "Reach The Top" for his album The Glamour Chase, which after many years in limbo was finally released in 2002.

One single, "Something Good", was taken from the album, but much to Circa's disappointment, neither the single nor the album sold in great numbers.

Chain (caste)

The Chain, sometimes also pronounced as Chai, are cultivating and fishing caste found in eastern Uttar Pradesh in India. They are a sub-group within the larger Kewat communinity of North India.

Origin

The Chai according to some traditions, were a community of Vaishyas, who lost caste, when they took to fishing. Other traditions make them out to be a branch of the Bind caste, and the two communities intermarry, with suggests a common origin. They are now recognized as a sub-group within the Kewat community, and they intermarry with other Kewat clans such as the Banaphar and Dhivar. The majority of the Chai are now cultivators, with a small number still employed as boatmen on the Ganges. They are Hindu, and have customs similar to other Kewat groups.

The Chai are found mainly in southern and eastern Uttar Pradesh, with concentrations in Mirzapur, Ghazipur, Varanasi, Gorakhpur, Basti and Faizabad. They speak Awadhi, although most also understand Hindi.
