A "woobie" is a piece of field gear originating in the United States military that can be attached to a standard issue poncho to provide additional warmth, as well as being usable as a blanket, sleeping bag or protective cover. It consists of quilted nylon with a polyester filling. It is attached to the poncho by means of integral lengths of material which are looped through the poncho's eyelets.
Poncho liners were first used by the U.S. military in the Vietnam War. They gained the nickname "woobie" later; that term may be derived from the name for a child's security blanket in the 1983 movie Mr. Mom.
Poncho liners. I wish I still had mine. :-)

A surplus store or disposals store is a business that sells items and goods that are used, purchased but unused, or past their use by date, and are no longer needed due to excess supply, decommissioning, or obsolescence. The surplus sold is often military, government, or industrial goods; in the case of the former two, the business is usually called a military surplus store, government surplus store, war surplus store, or army-navy store.

The Spanish dollar, also known as the piece of eight (Spanish: real de a ocho, dólar, peso duro, peso fuerte or peso), is a silver coin of approximately 38 mm (1.5 in) diameter worth eight Spanish reales. It was minted in the Spanish Empire following a monetary reform in 1497 with content 25.563 g (0.8219 ozt) fine silver. It was widely used as the first international currency because of its uniformity in standard and milling characteristics. Some countries countermarked the Spanish dollar so it could be used as their local currency.
Because the Spanish dollar was widely used in Europe, America, and the Far East, it became the first world currency by the 16th century.
The Spanish dollar was the coin upon which the original United States dollar was based (at 0.7735 troy ounces or 24.06 grams), and it remained legal tender in the United States until the Coinage Act of 1857. Many other currencies around the world, such as the Japanese yen and the Chinese yuan, were initially based on the Spanish dollar and other 8-real coins.[5] Most theories trace the origin of the "$" symbol, which originally had two vertical bars, to the pillars of Hercules wrapped in ribbons that appear on the reverse side of the Spanish dollar.
The term peso was used in Spanish to refer to this denomination, and it became the basis for many of the currencies in the former Spanish colonies, including the Argentine, Bolivian, Chilean, Colombian, Costa Rican, Cuban, Dominican, Ecuadorian, Guatemalan, Honduran, Mexican, Nicaraguan, Paraguayan, Philippine, Puerto Rican, Peruvian, Salvadoran, Uruguayan, and Venezuelan pesos. Of these, "peso" remains the name of the official currency in the Philippines, Mexico, Cuba, the Dominican Republic, Colombia, Chile, Argentina, and Uruguay.

A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. The location of a leak can be visually identified more easily if the water contains a colorant. Strength is usually tested by measuring permanent deformation of the container.
Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard. In some cases where a hydrostatic test is not practicable a pneumatic pressure test may be an acceptable alternative.
Testing of pressure vessels for transport and storage of gases is very important because such containers can explode if they fail under pressure.
Prarie dogs do the waveMany other aspects of prairie dog communication remain encoded—at least for now. One mysterious communique popular with several species is the “jump-yip,” a gesture-vocalization combo frequently compared to a stadium wave, in which many prairie dogs in a row cry aloud while tossing their arms (and sometimes their full bodies) into the air. An entire colony can get swept up in a jump-yip.

Thermophoresis (also thermomigration, thermodiffusion, the Soret effect, or the Ludwig–Soret effect) is a phenomenon observed in mixtures of mobile particles where the different particle types exhibit different responses to the force of a temperature gradient. This phenomenon tends to move light molecules to hot regions and heavy molecules to cold regions. The term thermophoresis most often applies to aerosol mixtures whose mean free path is comparable to its characteristic length scale L but may also commonly refer to the phenomenon in all phases of matter. The term Soret effect normally applies to liquid mixtures, which behave according to different, less well-understood mechanisms than gaseous mixtures. Thermophoresis may not apply to thermomigration in solids, especially multi-phase alloys.

The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.
In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system designated the AISI/SAE steel grades. In 1995 the AISI turned over future maintenance of the system to SAE because the AISI never wrote any of the specifications.
Today steel quotes and certifications commonly make reference to both SAE and AISI, not always with precise differentiation. For example, in the alloy/grade field, a certificate might refer to "4140", "AISI 4140", or "SAE 4140", and in most light-industrial applications any of the above is accepted as adequate, and considered equivalent, for the job at hand, as long as the specific specification called out by the designer (for example, "4140 bar per ASTM-A108" or "4140 bar per AMS 6349") is certified to on the certificate. The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard.
The SAE steel grade system's correspondence to other alloy numbering systems, such as the ASTM-SAE unified numbering system (UNS), can be seen in cross-referencing tables (including the ones given below).
The AISI system uses a letter prefix to denote the steelmaking process. The prefix "C" denotes open-hearth furnace, electric arc furnace or basic oxygen furnace steels, while "E" specifies only electric arc furnace steel.[2][3] A letter "L" within the grade name indicates lead as an added ingredient; for example, 12L14 is a common grade that is 1214 with lead added for machinability.
Suffixes may be added to the steel grade which specify the forming process used to create a part. These may include cold working (CDS), hot working (HR), quenching and tempering (Q&T), and other methods.

"The Way We Were" is a song by American singer Barbra Streisand from her fifteenth studio album of the same name. It was released as the album's lead single on September 27, 1973, through Columbia Records. The 7" single was distributed in two different formats, with the standard edition featuring B-side track "What Are You Doing the Rest of Your Life?"; the Mexico release instead included an instrumental B-side. The song was written by Alan Bergman, Marilyn Bergman, and Marvin Hamlisch, while production was solely handled by Marty Paich. "The Way We Were" was specifically produced for the record, in addition to three other tracks, including her then-upcoming single "All in Love Is Fair" (1974).
Its lyrics detail the melancholic relationship between the two main characters in the 1973 film of the same name. Its appeal was noted by several music critics, who felt its impact helped revive Streisand's career. The song also won two Academy Awards, which were credited to the songwriters of the track. The single was also a commercial success, topping the charts in both Canada and the United States, while peaking in the top 40 in Australia and the United Kingdom. Additionally, "The Way We Were" was 1974's most successful recording in the United States, where it was placed at number one on the Billboard Year-End Hot 100 singles list. It has since been certified Platinum by the RIAA for sales of over one million units. Streisand has also included "The Way We Were" on various compilation albums, with it most recently appearing on 2010's Barbra: The Ultimate Collection.
Several renditions and versions of the single exist, including one by American singer Andy Williams, who sang it for his thirty-second studio album of the same name in 1974. American band Gladys Knight & the Pips also recorded a cover for I Feel a Song (1974), which was commercially successful; it reached number four in the United Kingdom and number 11 in the United States.

The complaint tablet to Ea-nāṣir is a clay tablet that was sent to the ancient city-state Ur, written c. 1750 B.C. It is a complaint to a merchant named Ea-nāṣir from a customer named Nanni. Written in Akkadian cuneiform, it may be the oldest known written customer complaint. Discovered in the early 20th century by British archeologist Sir Charles Leonard Woolley, it is currently kept in the British Museum.
The tablet details that Ea-nāṣir traveled to Dilmun to buy copper and returned to sell it in Mesopotamia. On one particular occasion, he had agreed to sell copper ingots to Nanni. Nanni sent his servant with the money to complete the transaction. The copper was considered by Nanni to be sub-standard and was not accepted.
In response, Nanni created the cuneiform letter for delivery to Ea-nāṣir. Inscribed on it is a complaint to Ea-nāṣir about a copper delivery of the incorrect grade and issues with another delivery; Nanni also complained that his servant (who handled the transaction) had been treated rudely. He stated that, at the time of writing, he had not accepted the copper, but had paid for it.
In 2015, the tablet's content and Ea-nāṣir in particular gained popularity as an online meme.
When you came, you said to me as follows: "I will give Gimil-Sin (when he comes) fine quality copper ingots." You left then but you did not do what you promised me. You put ingots which were not good before my messenger (Sit-Sin) and said: "If you want to take them, take them; if you do not want to take them, go away!"
What do you take me for, that you treat somebody like me with such contempt? I have sent as messengers gentlemen like ourselves to collect the bag with my money (deposited with you) but you have treated me with contempt by sending them back to me empty-handed several times, and that through enemy territory. Is there anyone among the merchants who trade with Telmun who has treated me in this way? You alone treat my messenger with contempt! On account of that one (trifling) mina of silver which I owe(?) you, you feel free to speak in such a way, while I have given to the palace on your behalf 1,080 pounds of copper, and Umi-Abum has likewise given 1,080 pounds of copper, apart from what we both have had written on a sealed tablet to be kept in the temple of Šamaš.
How have you treated me for that copper? You have withheld my money bag from me in enemy territory; it is now up to you to restore (my money) to me in full.
Take cognizance that (from now on) I will not accept here any copper from you that is not of fine quality. I shall (from now on) select and take the ingots individually in my own yard, and I shall exercise against you my right of rejection because you have treated me with contempt.

David Wayne Hooks Memorial Airport (IATA: DWH, ICAO: KDWH, FAA LID: DWH) is a public-use airport located near the city of Tomball in unincorporated Harris County, Texas. It is 23 miles (37 km) northwest of the central business district of Houston. It is the busiest general aviation airport in Texas and one of the busiest general aviation airports in the United States. The airport is privately owned by Northwest Airport Management, LP.
The airport is notable because it is one of only a few privately owned airports with a Federal Aviation Administration control tower; the airport is owned by Northwest Airport Management, LP and managed by Amy Mounger and Alex Membreno.
On June 27, 2007, The Texas State Legislature approved Tomball's request to annex Hooks Airport even though the airport does not border the Tomball city limits. Since the airport is in the city of Houston's extraterritorial jurisdiction, the city of Tomball must get permission from Houston to annex the airport. As of summer of 2010, the annex still has not been finalized.

James Doohan of Star Trek first saw combat in WWII, landing in the 2nd Wave in a Recce Party at Juno Beach on D-Day. The 13th Field Regiment was interspersed with the Regina Rifle Regiment landing at "Nan" Sector of Juno Beach. After shooting two snipers, Doohan led his men to higher ground through a field of anti-tank mines, where they took defensive positions for the night. Crossing between command posts at 23:30 that night, Doohan was hit by six rounds fired from a Bren gun by a nervous Canadian sentry: four in his leg, one in the chest, and one through his right middle finger. The bullet to his chest was stopped by a silver cigarette case given to him by his brother. His right middle finger had to be amputated, something he would conceal on-screen during most of his career as an actor, sometimes with a flesh-colored glove with a "faux finger."

Gil Kane (born Eli Katz, Latvian: Elija Kacs; April 6, 1926 – January 31, 2000) was a Latvian-born American comics artist whose career spanned the 1940s to the 1990s and virtually every major comics company and character.
Kane co-created the modern-day versions of the superheroes Green Lantern and the Atom for DC Comics, and co-created Iron Fist and Adam Warlock with Roy Thomas for Marvel Comics. He was involved in the anti-drug storyline in The Amazing Spider-Man #96–98, which, at the behest of the U.S. Department of Health, Education, and Welfare, bucked the then-prevalent Comics Code Authority to depict drug abuse, and ultimately spurred an update of the Code. Kane additionally pioneered an early graphic novel prototype, His Name Is... Savage, in 1968, and a seminal graphic novel, Blackmark, in 1971.
In 1997, he was inducted into both the Will Eisner Comic Book Hall of Fame and the Harvey Award Jack Kirby Hall of Fame.

Helicopter Underwater Egress Training (also known as Helicopter Underwater Escape Training); often abbreviated as HUET, pronounced hue-wet, hue-way or you-way) is training provided to helicopter flight crews, offshore oil and gas industry, law enforcement personnel, and military personnel who are regularly transported by helicopters over water. As the name implies, the purpose of this training is to prepare passengers and crew for an emergency evacuation or egress in the event of a crash landing on water.
Helicopter Underwater Egress Training (also known as Helicopter Underwater Escape Training).
I did hear about that from some lifeguards. One of the people going for basic training couldn't swim and needed to learn to swim and then take that.

The Mie–Grüneisen equation of state is an equation of state that relates the pressure and volume of a solid at a given temperature.[1][2] It is used to determine the pressure in a shock-compressed solid. The Mie–Grüneisen relation is a special form of the Grüneisen model which describes the effect that changing the volume of a crystal lattice has on its vibrational properties. Several variations of the Mie–Grüneisen equation of state are in use.
Gustav Mie, in 1903, developed an intermolecular potential for deriving high-temperature equations of state of solids. In 1912, Eduard Grüneisen extended Mie's model to temperatures below the Debye temperature at which quantum effects become important. Grüneisen's form of the equations is more convenient and has become the usual starting point for deriving Mie–Grüneisen equations of state.

Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars (though being phased out as of 2005) and on a wide variety of piping connections, valves etc. FBE coatings are thermoset polymer coatings. They come under the category of protective coatings in paints and coating nomenclature. The name fusion-bond epoxy is due to resigning cross-link and the application method, which is different from a conventional paint. In 2020 the market size was quoted at 12 billion dollars.
The resin and hardener components in the dry powder FBE stock remain unreacted at normal storage conditions. At typical coating application temperatures, usually in the range of 180 to 250 °C (356 to 482 °F), the contents of the powder melt and transform to a liquid form. The liquid FBE film wets and flows onto the steel surface on which it is applied, and soon becomes a solid coating by chemical cross-linking, assisted by heat. This process is known as “fusion bonding”. The chemical cross-linking reaction taking place in this case is irreversible. Once the curing takes place, the coating cannot be returned to its original form by any means. Application of further heating will not “melt” the coating and thus it is known as a “thermoset” coating.

A pipeline bridge is a bridge for running a pipeline over a river or another obstacle. Pipeline bridges for liquids and gases are, as a rule, only built when it is not possible to run the pipeline on a conventional bridge or under the river. However, as it is more common to run pipelines for centralized heating systems overhead, for this application even small pipeline bridges are common.
Pipeline bridges may be made of steel, fiber reinforced polymer, reinforced concrete or similar materials. They may vary in size and style depending on the size of the pipeline being run. As there is normally a steady flow in pipelines, they can be designed as suspension bridges. They may also be added to an existing bridge. A pipeline bridge may be equipped with a walkway for maintenance purposes, but for safety and security reasons, the walkway is usually not open to the public.
One of the world's longest pipeline bridges, built in 1970, is 1,040 meters long and crosses the Fuji River in Shizuoka Prefecture of Japan. The highest at 393 m is Hegigio Gorge Pipeline Bridge in Papua New Guinea.

The Marquess of Queensberry Rules, also known as Queensbury Rules, are a code of generally accepted rules in the sport of boxing. Drafted in London in 1865 and published in 1867, they were named so as the 9th Marquess of Queensberry publicly endorsed the code, although they were written by a Welsh sportsman named John Graham Chambers from Llanelli, Carmarthenshire. The code of rules on which modern boxing is based, the Queensberry rules were the first to mandate the use of gloves in boxing.
The Queensberry Rules eventually superseded the London Prize Ring Rules (revised in 1853) and are intended for use in both professional and amateur boxing matches, thus separating it from the less-popular American Fair Play Rules, which were strictly intended for amateur matches. In colloquial use the term is sometimes used to refer to a sense of sportsmanship and fair play.

A mass flow meter, also known as an inertial flow meter, is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time.
The mass flow meter does not measure the volume per unit time (e.g. cubic meters per second) passing through the device; it measures the mass per unit time (e.g. kilograms per second) flowing through the device. Volumetric flow rate is the mass flow rate divided by the fluid density. If the density is constant, then the relationship is simple. If the fluid has varying density, then the relationship is not simple. For example, the density of the fluid may change with temperature, pressure, or composition. The fluid may also be a combination of phases such as a fluid with entrained bubbles. Actual density can be determined due to dependency of sound velocity on the controlled liquid concentration.

The idiom "the straw that broke the camel's back" describes a minor or routine action that causes an unpredictably large and sudden reaction due to the cumulative effect of previous small actions. It alludes to the proverb "it is the last straw that breaks the camel's back".
This gives rise to the phrase "the last straw", or "the final straw", meaning that the last one in a line of unacceptable occurrences causes a seemingly sudden and strong reaction.
The earliest known version of the expression comes in a theological debate on causality by Thomas Hobbes and John Bramhall in 1654–1684:
The last Dictate of the Judgement, concerning the Good or Bad, that may follow on any Action, is not properly the whole Cause, but the last Part of it, and yet may be said to produce the Effect necessarily, in such Manner as the last Feather may be said to break a Horses Back, when there were so many laid on before as there want but that one to do it.

Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current.
Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and steel storage tanks such as home water heaters; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; offshore wind farm foundations and metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust.
Cathodic protection can, in some cases, prevent stress corrosion cracking.
