Tie (engineering)

A tie, strap, tie rod, eyebar, guy-wire, suspension cables, or wire ropes, are an examples of linear structural components designed to resist tension. It is the opposite of a strut or column, which is designed to resist compression. Ties may be made of any tension resisting material.

Application in wood construction

In wood frame construction they are generally made of galvanized steel. Wood framing ties generally have holes allowing them to be fastened to the wood structure by nails or screws. The number and type of nails are specific to the tie and its use. The manufacturer generally specifies information as to the connection method for each of their products. Among the most common wood framing ties used is the hurricane tie or seismic tie used in the framing of wooden structures where wind uplift or seismic overturning is a concern.

Hurricane tie

A hurricane tie is used to help make a structure (specifically wooden structures) more resistant to high winds (such as in hurricanes), resisting uplift, racking, overturning, and sliding. Each of the crucial connections in a structure, that would otherwise fail under the pressures of high winds, have a corresponding type of tie, generally made of galvanized or stainless steel, and intended to resist hurricane-force and other strong winds.

Angiopoietin receptor

The angiopoietin receptors are receptors that bind angiopoietin.

TIE-1 and TIE-2 comprise the cell-surface receptors that bind and are activated by the angiopoietins, (Ang1, Ang2, Ang3, Ang4). The angiopoietins are protein growth factors required for the formation of blood vessels (angiogenesis).

Angiopoietins

The angiopoietins are protein growth factors that promote angiogenesis, the formation of blood vessels. There are now four identified angiopoietins: Ang1, Ang2, Ang3, Ang4. Ang1 and Ang4 function as agonistic or activating ligands for Tie2, whereas Ang2 and Ang3 behave as competitive antagonists. They function by binding their physiologic receptors, Tie-1 and Tie-2. These are receptor tyrosine kinases, so named because they mediate cell signals by inducing the phosphorylation of key tyrosines, thus initiating cell signalling. It is somewhat controversial which of the Tie receptors mediate functional signals downstream of Ang stimulation. But it is clear that at least Tie-2 is capable of physiologic activation as a result of binding the angiopoietins.

Vladimir Leontyevich Komarov

Vladimir Leontyevich Komarov (Russian: Влади́мир Лео́нтьевич Комаро́в; 1869–1945) was a Russian botanist.

Until his death in 1945, he was senior editor of the Flora SSSR (Flora of the U.S.S.R.), in full comprising 30 volumes published between 1934–1960. He was elected a corresponding member of the Russian Academy of Sciences in 1914 and its full member in 1920. He served as President of the Academy of Sciences of the USSR in 1936-1945.

The Komarov Botanical Institute and its associated Komarov Botanical Garden in Saint Petersburg are named after him.

Dan (newspaper)

Dan (Serbian Cyrillic: Дан, pronounced [dâːn]; English: The Day) is a daily newspaper published in Montenegro. It took its name from the old day Cetinje monthly newspaper that was published in the old Montenegrin state at the beginning of the 20th century. As of 2009 it held the second place after Vijesti with a share of an estimated 31,6% of the country's total readers.

History and profile

The first issue of Dan appeared on 31 December 1999. Right from its start, Dan was one of the harshest critics of Milo Đukanović's regime in Montenegro. In May 2001, as Croatian magazine Nacional) began a series of articles and insider interviews on state-sponsored cigarette smuggling in Montenegro under Djukanovic's regime, Dan was the only media outlet in the country to bring the details of the 'Nacional affair' to the Montenegrin public.

On 27 May 2004 Dan founder and editor-in-chief Duško Jovanović was assassinated on a Podgorica street in front of the paper's offices. Even though a prolonged police investigation produced a couple of arrests, along with an immediate assassin-suspect currently on trial, the individuals behind the murder have still not been identified. It is alleged that the DPS-controlled government both sponsored and covered up the event.

Dan, Israel

Dan (Hebrew: דָּן) is a kibbutz in the northern part of the Hula Valley, at the foot of Mt. Hermon, in the Upper Galilee, Israel.

History

Kibbutz Dan was founded in 1939 by Jewish farmers from Transylvania. It is affiliated with the Hashomer Hatzair movement. In 1947, the population was 340.Dan was one of two villages established in honour of Menachem Ussishkin. It was named after the Israelite town of "Dan" mentioned in 1 Kings 12:29, 1 Samuel 3:20 and Genesis 14:14, and which has been identified with nearby Tel Dan. Kibbutz Dan is located in the territory of the Israelite tribe of Dan (Joshua 19:47). It suffered heavy losses during the 1948 Arab-Israel war, bearing the brunt of the Syrian invasion.

Economy

One of the first economic branches was a cooperative trout-breeding venture with nearby Kibbutz Dafna.

The Caviar Galilee Company, which exports caviar under the brand name "Karat Caviar," is based on the kibbutz. According to Eric Ripert, chef and proprietor of Le Bernadin, considered the leading seafood restaurant in New York, and Jean Francois Bruel, chef of Daniel, a Michelin 3-star rated restaurant in Manhattan's Upper East Side, the best caviar on the market today is produced by Kibbutz Dan. The kibbutz exports caviar to the United States, Europe, Russia, Japan, Singapore and Canada. In 2011, the company produced 3,000 kilograms. It has plans to increase production gradually to 8,000 kilograms a year.
