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.

Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel and others.
The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat (heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately 42 °C (108 °F), or oils burned in cotton- or wool-wick burners. In a stricter sense, fuel oil refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha.
Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such as those in propane, naphtha, gasoline, and kerosene, have relatively low boiling points, and are removed at the start of the fractional distillation process. Heavier petroleum-derived oils like diesel fuel and lubricating oil are much less volatile and distill out more slowly.

The Villa Farnese, also known as Villa Caprarola, is a pentagonal mansion in the town of Caprarola in the province of Viterbo, Northern Lazio, Italy, approximately 50 kilometres (31 mi) north-west of Rome. This villa should not be confused with the Palazzo Farnese and the Villa Farnesina, both in Rome. A property of the Republic of Italy, Villa Farnese is run by the Polo Museale del Lazio.
The Villa Farnese is situated directly above the town of Caprarola and dominates its surroundings. It is a massive Renaissance and Mannerist construction, opening to the Monte Cimini, a range of densely wooded volcanic hills. It is built on a five-sided plan in reddish gold stone; buttresses support the upper floors. As a centerpiece of the vast Farnese holdings, Caprarola was always an expression of Farnese power, rather than a villa in the more usual agricultural or pleasure senses.

Process engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as well as the law of conservation of mass, process engineers can develop methods to synthesize and purify large quantities of desired chemical products. Process engineering focuses on the design, operation, control, optimization and intensification of chemical, physical, and biological processes. Process engineering encompasses a vast range of industries, such as agriculture, automotive, biotechnical, chemical, food, material development, mining, nuclear, petrochemical, pharmaceutical, and software development. The application of systematic computer-based methods to process engineering is "process systems engineering".
Coraline is a 2009 American stop-motion animated dark fantasy horror film written and directed by Henry Selick and based on Neil Gaiman's novella of the same name. Produced by Laika as the studio's first feature film, it features the voice talents of Dakota Fanning, Teri Hatcher, Jennifer Saunders, Dawn French, Keith David, John Hodgman, Robert Bailey Jr., and Ian McShane. The film tells the story of its titular character discovering an idealized parallel universe behind a secret door in her new home, unaware that it contains a dark and sinister secret.
Fourthly, I hope you’ll make mistakes. If you make mistakes, it means you’re out there doing something. And the mistakes in themselves can be very useful. I once misspelled Caroline in a letter, transposing the A and the O, and I thought, “Coraline looks almost like a real name.”

In materials science and engineering, the yield point is the point on an stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible and is known as plastic deformation.
The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing permanent deformation. In some materials, such as aluminium, there is a gradual onset of non-linear behavior, making the precise yield point difficult to determine. In such a case, the offset yield point (or proof stress) is taken as the stress at which 0.2% plastic deformation occurs. Yielding is a gradual failure mode which is normally not catastrophic, unlike ultimate failure.

A ball valve is a flow control device which uses a hollow, perforated and pivoting ball to control fluid flowing through it. It is open when the ball's hole is in line with the flow inlet and closed when it is pivoted 90-degrees by the valve handle, blocking the flow. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. The shut position 1/4 turn could be in either clockwise or counter-clockwise direction.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack the fine control of those alternatives, in throttling applications.
Proper time is a concept in Special Relativity that refers to the time experienced by an observer who is at rest relative to a given event or object. It is defined as the time interval measured by a clock that is co-located with the observer. Proper time is frame-dependent and is invariant under Lorentz transformations -- which describe the transformation of spacetime coordinates between different inertial frames.
In the context of spacetime diagrams, where time is plotted on the vertical axis and space on the horizontal axis, the worldline of an object at rest relative to an observer forms a vertical line with a slope of zero. This worldline represents the proper time experienced by the object, and it is a straight line.
"Down" always points to where time runs the slowest.

John Victor Romita Sr. (January 24, 1930 – June 12, 2023) was an American comic book artist best known for his work on Marvel Comics' The Amazing Spider-Man and for co-creating characters including Mary Jane Watson, the Punisher, and Wolverine. Romita was the father of John Romita Jr., also a comic book artist and husband of Virginia Romita, for many years Marvel's traffic manager.
His first comics work was in 1949 as a ghost artist for Timely Comics, the precursor to Marvel, through which Romita met editor-in-chief Stan Lee. In 1951, Romita began drawing horror, war, and romance comics for Atlas Comics (previously Timely), and also drew his first superhero work, a 1950s revival of Captain America. He began working exclusively for DC Comics from 1958–1965 and was the artist for many of their romance comics. During these years, Romita further developed his ability to draw beautiful women, which he later became well-known for.
Romita joined Marvel in 1965, initially drawing Daredevil comics. In 1966, Spider-Man artist and co-creator Steve Ditko left Marvel, and Romita was chosen by writer Lee as the new artist for The Amazing Spider-Man title. Within a year of Romita becoming the Spider-Man artist, The Amazing Spider-Man rose from Marvel's second-best-selling title to the company's top-seller. Romita brought a new romance style to Spider-Man comics that soon became the new house style for the character. In June 1973, Romita was promoted to Marvel's art director and heavily influenced the look of Marvel comics throughout the 1970s and 1980s.
He was inducted into the Will Eisner Comic Book Hall of Fame in 2002.

In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.
These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a "pig launcher" (or "launching station")—an oversized section in the pipeline, reducing to the normal diameter. The launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push the pig along the pipe until it reaches the receiving trap—the "pig catcher" (or "receiving station").

Royal Canin is a French manufacturer of cat and dog food. A subsidiary of Mars, Incorporated, the company also undertakes research into the formulation and testing of breed and symptom specific nutritional requirements of dogs and cats.
The company was established by French veterinary surgeon Jean Cathary, after he successfully treated a number of skin and coat conditions in pets by feeding them a cereal-based diet he prepared in his garage. He realized that nutrition was an important part of pets' health. After importing an extruder from the United States, a process used in this industry for the first time in 1956, the company was the first to manufacture dry pet food in France. Aimed primarily at breeders, production steadily increased and distribution extended further into the European market. Royal Canin was sold to the Guyomarc'h Group in 1972, and underwent a further period of expansion, especially in the area of research and development, before being purchased by the Paribas Bank in 1990. The company was floated on the French stock exchange but removed later after it was sold to Mars, Incorporated in 2002.

A hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure used to diagnose problems of the liver, gallbladder and bile ducts.
For a HIDA scan, also known as cholescintigraphy or hepatobiliary scintigraphy, a radioactive tracer is injected into a vein in the arm. The tracer travels through the bloodstream to the liver, where the bile-producing cells take it up. The tracer then travels with the bile into the gallbladder and through the bile ducts to the small intestine.
A nuclear medicine scanner, called a gamma camera, tracks the flow of the tracer from the liver into the gallbladder and small intestine and creates computer images.

Hawk and Dove are a superhero team appearing in American comic books published by DC Comics. Created by Steve Ditko and Steve Skeates, they appeared in Showcase #75 (June 1968) during the Silver Age of Comic Books. The duo has existed in multiple incarnations over the years across several eponymous ongoing series and miniseries, and has also appeared in a number of recurring roles and guest appearances in titles such as Teen Titans, Birds of Prey, and Brightest Day. The duo originated as teenage brothers Hank Hall as Hawk and Don Hall as Dove. Following Don's death in Crisis on Infinite Earths (1985), Dawn Granger assumed the role of Dove in Hawk & Dove #1 (October 1988). The mantle of Hawk would later be taken up by Dawn's sister Holly Granger in 2003 after Hank was killed during 1994's Zero Hour: Crisis in Time! until her death and Hank's resurrection in Blackest Night (2009). An unrelated team consisting of military cadet Sasha Martens as Hawk and rock musician Wiley Wolverman as Dove also appeared as the focus of a 1997 miniseries. The pairing of Hank and Dawn serve as the current and most commonly published incarnation of the team.

Vinicunca, or Winikunka, also called Montaña de Siete Colores (literally: Mountain of seven colors), Montaña de Colores (Mountain of colors) or Montaña Arcoíris (Rainbow Mountain), is a mountain in the Andes of Peru with an altitude of 5,200 metres (17,100 ft) above sea level. It is located on the road to the Ausangate mountain, in the Cusco region, between Cusipata District, province of Quispicanchi, and Pitumarca District, province of Canchis.
Tourist access requires a two-hour drive from Cusco and a walk of about 5 kilometers (3.1 mi), or a three-and-a-half-hour drive through Pitumarca and a one-half-kilometre (0.31 mi) steep walk (1–1.5 hours) to the hill. As of 2019, no robust methods of transportation to Vinicunca have been developed to accommodate travelers, as it requires passage through a valley.

The Tourlitis Lighthouse of Andros is located at the entrance of the port of Chora opposite the Venetian Castle. It is the only lighthouse in Europe built on a rock in the sea.
It was constructed in 1887 and operated for the first time January 1, 1897. It had a height of 7 meters, a focal height of 36 meters and was a surveying E class with a flare of 11 nautical miles. It stood out for its operation, since it is the first automatic lighthouse in Greece with technology that gave it great reliability, because it did not require constant surveillance.
During The Second World War, in September 1943, it was destroyed by german bombardments. In 1996 it was reconstructed at the expense of the Goulandris family.
The stones used for its construction came from northern Epirus. Today, the Tourlitis Lighthouse has become a stamp and is part of the series of stamps "Lighthouses of Greece" of the Greek Post Office.

In the U.S., Indiana Jones and The Temple of Doom and Gremlins (1984) led to the creation of the PG-13 rating. Many people felt both movies were too violent for a PG rating, but not violent enough for an R rating. Some believed that both films would have been rated R if Steven Spielberg's name hadn't been attached. The rating change according to the MPAA had been planned as early as 1977 but the release of this movie and also Gremlins (1984) ultimately fueled the creation of it. The Flamingo Kid (1984) was the first film to receive a PG-13 rating, but it sat on the shelves for five months before being released. Red Dawn (1984) was the first film released with a PG-13 rating.

Kim Cattrall left the set of Big Trouble in Little China at 4:30 p.m. each day, then performed in a production of Anton Chekhov's Three Sisters. Cattrall remembers having to explain to studio bosses who Chekhov was. "My film career subsidized my theater career," she said. "If I only did theater, I would have had to waitress, and I didn't want to waitress."
Five United States presidents (Ulysses S. Grant, Rutherford B. Hayes, James Garfield, Benjamin Harrison, and William McKinley) served in the US Civil War. All five were born in Ohio. McKinley is the only one of the five to have begun his career as an enlisted soldier. Hayes is one of only two US presidents to have been wounded in combat (the other being James Monroe, wounded during the American Revolution). Two of the five (Garfield and McKinley) were assassinated while serving as president.
