Forensic Arts
Forensic art is any art used in law enforcement or legal proceedings. Forensic art is used to assist law enforcement with the visual aspects of a case, often using witness descriptions and video footage. It is a highly specialized field that covers a wide range of artistic skills, such as composite drawing, crime scene sketching, image modification and identification, courtroom drawings, demonstrative evidence, and postmortem and facial approximation aids. It is rare for a forensic artist to specialize in more than one of these skills. Many forensic artists do the job as a collateral duty to their "regular" job in law enforcement, such as police officer, crime scene tech, etc. Such forensic artists perform their work while on a fixed salary and are not additionally compensated for artistic duties. There are few full-time forensic artist jobs available. Most full-time artists work in large cities, or in state or federal agencies. "Freelancing" in forensic art is a difficult career path, as ties to law enforcement are a necessary part of the job, and agencies have limited budgets to pay outside contractors. The skill of facial approximation is closely associated and related to forensic anthropology in that an artist specializes in the reconstruction of the remains of a human body. Generally this discipline focuses on the human face for identification purposes. The forensic artist can create a facial approximation in a number of ways to include 2D (drawings), 3D (sculptures) and other methods using new computer technology. Forensic artists generally can add greater character and make their subjects come back to "life".

Profession (Religious)
The term religious profession is used in many western-rite Christian denominations (including those of Roman Catholic, Anglican, Lutheran, and other traditions) to refer to the solemn admission of men or women into a religious order by means of public vows. The term is defined in the 1983 Code of Canon Law of the Roman Catholic Church in relation to members of religious institutes as follows: Canon Law also recognizes public profession of the three evangelical counsels on the part of Christians who live the "eremitic or anchoritic life" without being members of a religious institute: The three evangelical counsels, which are considered in greater depth in the article about them, are those of chastity, poverty and obedience. The Benedictine religious profession of "stability, conversion of manners and obedience", though historically preceding the profession of the evangelical counsels by several centuries, includes the three evangelical counsels implicitly. Some orders add to the three evangelical counsels special vows inspired by the purpose of their own founder (see in particular the fourth vow unique to the Society of Jesus). Religious profession is often associated with the granting of a religious habit, which the newly professed receives, with or without ceremony, from the superior of the institute or from the bishop. Acceptance of the habit implies acceptance of the obligation of membership of the religious institute, including the vows of chastity, poverty and obedience. Religious profession can be temporary or perpetual: "Temporary profession is to be made for the period defined by the institute's own law. This period may not be less than three years nor longer than six years." "When the period of time for which the profession was made has been completed, a religious who freely asks, and is judged suitable, is to be admitted to a renewal of profession or to perpetual profession; otherwise, the religious is to leave." Conditions for making a temporary religious profession are a minimum age of 18 years, completion of a regular novitiate, freedom of choice on the part of the person making the profession, and acceptance by the superior after a vote by the superior's council. Additional conditions for making perpetual profession are a minimum age of 21 years and the completion of at least three years of temporary profession. The traditional distinction between simple and solemn vows is no longer taken into account for canonical effects.

Satellite System
A satellite system is a set of gravitationally bound objects in orbit around a planetary mass object (incl. sub-brown dwarfs and rogue planets) or minor planet, or its barycenter. Generally speaking, it is a set of natural satellites (moons), although such systems may also consist of bodies such as circumplanetary disks, ring systems, moonlets, minor-planet moons and artificial satellites any of which may themselves have satellite systems of their own (see Subsatellites). Some bodies also possess quasi-satellites that have orbits gravitationally influenced by their primary, but are generally not considered to be part of a satellite system. Satellite systems can have complex interactions including magnetic, tidal, atmospheric and orbital interactions such as orbital resonances and libration. Individually major satellite objects are designated in Roman numerals. Satellite systems are referred to either by the possessive adjectives of their primary (e.g. "Jovian system"), or less commonly by the name of their primary (e.g. "Jupiter system"). Where only one satellite is known, or it is a binary with a common centre of gravity, it may be referred to using the hyphenated names of the primary and major satellite (e.g. the "Earth-Moon system"). Many Solar System objects are known to possess satellite systems, though their origin is still unclear. Notable examples include the largest satellite system, the Jovian system, with 80 known moons (including the large Galilean moons) and the Saturnian System with 83 known moons (and the most visible ring system in the Solar System). Both satellite systems are large and diverse. In fact all of the giant planets of the Solar System possess large satellite systems as well as planetary rings, and it is inferred that this is a general pattern. Several objects farther from the Sun also have satellite systems consisting of multiple moons, including the complex Plutonian system where multiple objects orbit a common center of mass, as well as many asteroids and plutinos. Apart from the Earth-Moon system and Mars' system of two tiny natural satellites, the other terrestrial planets are generally not considered satellite systems, although some have been orbited by artificial satellites originating from Earth. Little is known of satellite systems beyond the Solar System, although it is inferred that natural satellites are common. J1407b is an example of an extrasolar satellite system. It is also theorised that Rogue planets ejected from their planetary system could retain a system of satellites.

Luxembourg Leaks
Luxembourg Leaks (sometimes shortened to Lux Leaks or LuxLeaks) is the name of a financial scandal revealed in November 2014 by a journalistic investigation conducted by the International Consortium of Investigative Journalists. It is based on confidential information about Luxembourg's tax rulings set up by PricewaterhouseCoopers from 2002 to 2010 to the benefits of its clients. This investigation resulted in making available to the public tax rulings for over three hundred multinational companies based in Luxembourg. The LuxLeaks' disclosures attracted international attention and comment about tax avoidance schemes in Luxembourg and elsewhere. This scandal contributed to the implementation of measures aiming at reducing tax dumping and regulating tax avoidance schemes beneficial to multinational companies. The judicial aspects of this case concern the persons charged by Luxembourg justice for participating in the revelations. No multinational company was charged. The LuxLeaks trial took place in spring 2016 and led to the condemnation of the two whistleblowers. The appeal trial's judgment was delivered in March 2017, upholding monetary fines and reducing the suspended jail sentence for Deltour.

More Hall Annex
The More Hall Annex, formerly the Nuclear Reactor Building, was a building on the campus of the University of Washington (UW) in Seattle, Washington, United States, that once housed a functional nuclear research reactor. It was inaugurated in 1961 and shut down in 1988, operating at a peak of 100 kilowatts thermal (kWt), and was officially decommissioned in 2007. The reactor was housed in a reinforced concrete building designed in the Brutalist architectural style by UW faculty members. They designed the reactor room with large windows that allowed observation from the outside, in an attempt to demonstrate the safety of nuclear energy. The Nuclear Reactor Building was added to the National Register of Historic Places in 2009, after a campaign led by an architecture student in response to the proposed demolition of the building. A later demolition plan prompted a lawsuit from preservation groups, which ended with a court ruling exempting the building from the city's landmarks-preservation ordinance. While this decision was eventually overturned, the university demolished the building in July 2016 and replaced it with a new computer science building that opened in February 2019.

Epson HX-20
The Epson HX-20 (also known as the HC-20) was the first "true" laptop computer. It was invented in July 1980 by Yukio Yokozawa, who worked for Suwa Seikosha, a branch of Japanese company Seiko (now Seiko Epson), receiving a patent for the invention. It was announced in 1981 as the HC-20 in Japan, and was introduced by Epson in North America as the HX-20 at the 1981 COMDEX computer show in Las Vegas, where it drew significant attention for its portability. It had a mass-market release in July 1982, as the HC-20 in Japan and as the Epson HX-20 in North America. The size of an A4 notebook and weighing 1.6 kg, it was hailed by BusinessWeek magazine as the "fourth revolution in personal computing".
