Shrink wrap

Shrink wrap, also shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.

Composition

The most commonly used shrink wrap is polyolefin. It is available in a variety of thicknesses, clarities, strengths and shrink ratios. The two primary films can be either crosslinked, or non crosslinked. Other shrink films include PVC, Polyethylene, Polypropylene, and several other compositions.

Coextrusions and laminations are available for specific mechanical and barrier properties for shrink wrapping food. For example, five layers might be configuration as EP/EVA/copolyester/EVA/EP, where EP is ethylene-propylene and EVA is ethylene-vinyl acetate copolymer.

Manufacture

A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional).

List of Dexter episodes

Dexter is an American television drama that was broadcast on the premium cable channel Showtime from October 1, 2006 to September 22, 2013. A total of 96 episodes of Dexter were broadcast over eight seasons. The series is based on characters created by Jeff Lindsay for his "Dexter" series of novels. The series follows the life of Dexter Morgan (Michael C. Hall), a Miami Metro Police Department blood pattern analyst with a double life. While investigating murders in the homicide division, Dexter hunts and kills murderers and criminals who have escaped the justice system. Although the first season is based on the events of Darkly Dreaming Dexter, the series' subsequent seasons do not follow the novels in the series. Departing from the narrative of Lindsay's second Dexter novel Dearly Devoted Dexter, the show's writer Daniel Cerone said that the writers "didn't see the opportunity in the second book" to adapt it.

The series has received generally favorable reviews from critics, while the second season received universal acclaim. The pilot episode, which aired in the USA on October 1, 2006, attracted more than a million viewers, giving Showtime its highest series ratings in nearly two years. Encouraged by its critical success and high ratings, CBS began broadcasting Dexter for free-to-air on February 17, 2008, thus making Dexter the first program in two decades to air on a national broadcast network after being shown on a premium cable channel. Eight seasons comprising twelve episodes each have been broadcast in the United States and abroad. All eight seasons have been released on DVD and on Blu-ray; box sets containing the first three seasons were released on August 18, 2009, on both DVD and Blu-ray.

OK

"OK" (/oʊkeɪ/; also spelled "okay", "ok", or "O.K.") is a word denoting approval, acceptance, agreement, assent, or acknowledgment. "OK", as an adjective, can also express acknowledgment without approval. "OK" has frequently turned up as a loanword in many other languages.

As an adjective, "OK" means "adequate", "acceptable" ("this is OK to send out"), "mediocre" often in contrast to "good" ("the food was OK"); it also functions as an adverb in this sense. As an interjection, it can denote compliance ("OK, I will do that"), or agreement ("OK, that is fine"). As a verb and noun it means "assent" ("the boss OKed the purchase" and "the boss gave his OK to the purchase"). As a versatile discourse marker (or back-channeling item), it can also be used with appropriate voice tone to show doubt or to seek confirmation ("OK?" or "Is that OK?").

Proposed etymologies

Numerous explanations for the origin of the expression have been suggested, but few have been discussed seriously by linguists. The following proposals have found mainstream recognition.

Orenstein & Koppel

Orenstein & Koppel (normally abbreviated to "O&K") was a major German engineering company specialising in railway vehicles, escalators, and heavy equipment. It was founded on April 1, 1876 in Berlin by Benno Orenstein and Arthur Koppel.

Originally a general engineering company, O&K soon started to specialise in the manufacture of railway vehicles. The company also manufactured heavy equipment and escalators. O&K pulled out of the railway business in 1981. Its escalator-manufacturing division was spun off to the company's majority shareholder at the time, Friedrich Krupp AG Hoesch-Krupp, in 1996, leaving the company to focus primarily on construction machines. The construction-equipment business was sold to New Holland Construction, at the time part of the Fiat Group, in 1999.

Founding and railway work

The Orenstein & Koppel Company was a mechanical-engineering firm that first entered the railway-construction field, building locomotives and other railroad cars.

First founded in 1892 in Schlachtensee, in the Zehlendorf district of Berlin, and known as the Märkische Lokomotivfabrik, the O&K factories expanded to supply the Imperial German Army under Kaiser Wilhelm II with field-service locomotives, or Feldbahn. O&K supplied all manner of railway equipment to the Army. Because of strained capacity at the Schlachtensee shops, work transferred in 1899 to a site in Nowawes, later Babelsberg, near Potsdam. Around 1908, O&K acquired the firm of Gerlach and König in Nordhausen, building petrol and diesel locomotives there under the trade mark "Montania".

Omar Khadr

Omar Ahmed Algredr Khadr (born September 19, 1986) is a Canadian who was convicted of murder after he allegedly threw a grenade during an armed conflict in Afghanistan that resulted in the death of an American soldier. At the time, he was 15 years old and had been brought to Afghanistan by his father, who was affiliated with an extreme religious group. During the conflict Khadr was badly wounded, and captured by the Americans. He was subsequently held at Guantanamo Bay for 10 years. After extensive torture, he pleaded guilty to murder in October 2010 to several purported war crimes prior to being tried by a United States military commission. He was the youngest prisoner and last Western citizen to be held by the United States at Guantanamo Bay. He accepted an eight-year sentence, not including time served, with the possibility of a transfer to Canada after at least one year to serve the remainder of the sentence.

During a firefight on July 27, 2002, in the village of Ayub Kheyl, Afghanistan, in which several Taliban fighters were killed, Khadr, not yet 16, was severely wounded. After being detained at Bagram, he was sent to Guantanamo Bay detention camps, in Cuba. During his detention, he was interrogated by Canadian as well as US intelligence officers.
