Sophia (Gnosticism)
Sophia (Koinē Greek: Σοφíα "Wisdom", Coptic: ⲧⲥⲟⲫⲓⲁ "the Sophia") is a major theme, along with Knowledge (γνῶσις gnosis, Coptic sooun), among many of the early Christian knowledge-theologies grouped by the heresiologist Irenaeus as gnostikoi (γνωστικοί), ‘knowing’ or ‘men that claimed to have deeper wisdom’. Gnosticism is a 17th-century term expanding the definition of Irenaeus' groups to include other syncretic and mystery religions. In Gnosticism, Sophia is a feminine figure, analogous to the human soul but also simultaneously one of the feminine aspects of God. Gnostics held that she was the syzygy (female twin divine Aeon) of Jesus (i.e. the Bride of Christ), and Holy Spirit of the Trinity. She is occasionally referred to by the Hebrew equivalent of Achamōth (Ἀχαμώθ, Hebrew: חכמה‎ chokhmah) and as Prunikos (Προύνικος). In the Nag Hammadi texts, Sophia is the lowest Aeon, or anthropic expression of the emanation of the light of God. She is considered to have fallen from grace in some way, in so doing creating or helping to create the material world.

North–South Divide (England)
In England, the term North–South divide refers to the cultural, economic, and social differences between: The status of the Midlands is often disputed, however counties in the higher midlands, such as West Midlands County (Walsall Metropolitan Borough and Wolverhampton are seen as north too due to their proximity to Staffordshire and Shropshire), Shropshire, Derbyshire, Nottinghamshire, Lincolnshire, Leicestershire, and Staffordshire, are culturally very Northern. A grouping of Central England based on UK EU parliamentary constituency boundaries combines the Midlands and East Anglia. In political terms, the South, and particularly the South-East (outside Greater London) and East Anglia, is largely centre-right, and supportive of the Conservative Party, while Northern England (particularly the towns and cities) is generally more supportive of the Labour Party. An article in The Economist (15–21 September 2012) argued that the gap between the north and south in life expectancy, political inclinations and economics trends was growing to the extent that they were almost separate countries.

DeLorean DMC-12
The DeLorean DMC-12 (commonly referred to simply as "the DeLorean", as it was the only model ever produced by the company) is a sports car originally manufactured by John DeLorean's DeLorean Motor Company for the American market from 1981 to 1983. The car features gull-wing doors and an innovative fiberglass body structure with a steel backbone chassis, along with external brushed stainless-steel body panels. It became widely known and iconic for its appearance, and because a modified DMC-12 was immortalized as the DeLorean time machine in the Back to the Future media franchise. The first prototype appeared in October 1976. Production officially began in 1981 in Dunmurry, a suburb of southwest Belfast, Northern Ireland, where the first DMC-12 rolled off the production line on January 21. Over the course of production, several features of the car were changed, such as the hood style, wheels, and interior. About 9,000 DMC-12s were made before production halted in early 1983. The DMC-12 was the only model produced by the company, which was later liquidated as the US car market went through its largest slump since the 1930s. In 2007, about 6,500 DeLorean Motor cars were thought to still exist. In 1995, Stephen Wynne, a British entrepreneur from Liverpool, created a separate company based in Texas using the "DeLorean Motor Company" name. Wynne acquired the trademark on the stylized "DMC" logo shortly thereafter, along with the remaining parts inventory of the original DeLorean Motor Company. The company builds new cars at its suburban Humble, Texas location from new old stock (NOS) parts, original equipment manufacturer (OEM), and reproduction parts on a "made to order" basis using existing vehicle identification number (VIN) plates. On January 27, 2016, DMC in Texas announced that it planned to build about 300–325 replica 1982 DMC-12 cars, each projected to cost just under US$100,000.

Plasma technology water purification
Plasma technology water purification is a new water treatment technology developed according to the trend of industrial water use in the 21st century. It is effective, efficient, scalable, versatile and customizable. These technologies must be able to adapt to new contaminants, reduce energy consumption, maintain or improve the proportionality between power and flow, demonstrate various flow capacities, minimize the transformation of existing infrastructure, prepare for imminent regulations, and tailor chemistry to site-specific requirements. New methods of water treatment by plasma must have all the above-mentioned properties and pose the least risk to public health. NTAPPs and their chemical reactions release energy and reactive chemical species that can kill bacteria and microorganisms, resulting in the disinfection of water. The advantage of this technique is that it can be performed in ambient air under atmospheric pressure without a vacuum system. Furthermore, NTAPP does not involve chemical products such as Cl. NTAPP can be used for water treatment in three ways: via direct, indirect, and bubbling methods.

Levirate Marriage
Levirate marriage is a type of marriage in which the brother of a deceased man is obliged to marry his brother's widow. The term levirate is itself a derivative of the Latin word levir meaning "husband's brother". Levirate marriage has been practiced by societies with a strong clan structure in which exogamous marriage (i.e. marriage outside the clan) was forbidden. It has been known in many societies around the world.

Physical and Chemical Aspects of Fog Water
Fog water have been rapidly increasing due to its negative impacts on different environmental processes. However, fog water harvesting has become beneficial in various countries to overcome water scarcity. Accurate fog forecasting remains a challenging issue due to its spatio-temporal variability and uncertainties despite the development and efforts made to understand its chemistry and microphysics. The literature proved that the decrease in fog frequency over time in most countries is mainly attributed to the improvement in air quality or the change in regional climatic conditions.

400 kV Double-Circuit Transmission Lines
A high-voltage AC double-circuit 400 kV overhead power transmission line runs from the city of Elk (Poland) to the city of Alytus (Lithuania). This international 400 kV power transmission line is potentially one of the strongest magnetic field-generating sources in the area. This 400 kV voltage double-circuit overhead transmission line and its surroundings were analyzed using the mathematical analytical methods of superposition and reflections. This research paper includes the calculation of the numerical values of the magnetic field and its distribution. The research showed that the values of the magnetic field strength near the international 400 kV power transmission line exceed the threshold values permitted by relevant standards. This overhead power line is connected to the general (50 Hz) power system and generates a highly intense magnetic field. It is suggested that experimental trials should be undertaken in order to determine the maximum values of the magnetic field strength. For the purpose of mitigating these values, it is suggested that the height of the support bars should be increased or that any individual and commercial activities near the object under investigation should be restricted.

Cruise Tourism
Cruise tourism is one of the leading industries suffering from covid-19 recently. Cruise tourism uses cruise ships with elegant services and various entertainment facilities as a means of transportation for scenic coastal tourist destinations. In particular, in accordance with the recent trend of increasing the size of ships, cruise lines have expanded the size and facilities of ships, and have continued to increase the maximum number of boarding ships. The cruise travel process and intensive entertainment system turned out to be a tourism structure vulnerable to the covid-19 pandemic. Will cruise tourism be extinguished? Should we prepare for the post-Pandermic cruise tourism era?

Monochromatic X-rays
Monochromatic X-ray has a single energy level in contrast to white X-rays used in conventional radiation therapy. Irradiation of high Z elements such as gadolinium, gold and silver with a monochromatic X-ray can result in photoelectric effects that includes the release of the Auger electrons that have strong cell killing effect. To apply this principle to cancer therapy, various nanoparticles loaded with high Z elements have been developed that enabled high Z elements to be delivered to tumor. The recent addition is gadolinium-loaded mesoporous silica nanoparticle (Gd-MSN). Tumor spheroids have been used as a convenient tumor model to demonstrate that monochromatic X-rays with energy level at or higher than the K-edge energy of gadolinium can destruct tumor mass that has Gd-MSN distributed throughout tumor spheroids.

Linguistic Universal
A linguistic universal is a statement that is true for all natural languages. For example, All languages have nouns and verbs, or All spoken languages have consonants and vowels. Research in this area of linguistics is closely tied to linguistic typology, and intends to reveal information about how the human brain processes language. The field was largely pioneered by the linguist Joseph Greenberg, who from a set of some thirty languages derived a set of basic universals, mostly dealing with syntax.

Atonement in Christianity
In Christian theology, atonement describes how human beings can be reconciled to God through Christ's sacrificial suffering and death. Atonement refers to the forgiving or pardoning of sin in general and original sin in particular through the suffering, death and resurrection of Jesus, enabling the reconciliation between God and his creation. Within Christianity there are, historically, three or four main theories for how such atonement might work: Other theories include recapitulation theory, the "shared atonement" theory and scapegoat theory. The English word 'atonement' originally meant "at-one-ment", i.e. being "at one", in harmony, with someone. It is used to describe the saving work that God did through Christ to reconcile the world to himself, and also of the state of a person having been reconciled to God. Throughout the centuries, Christians have used different metaphors and given differing explanations of the atonement to express how the atonement might work. Churches and denominations may vary in which metaphor or explanation they consider most accurately fits into their theological perspective; however all Christians emphasize that Jesus is the Saviour of the world and through his death the sins of humanity have been forgiven.

Cyclic Quadrilateral
In Euclidean geometry, a cyclic quadrilateral or inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. The center of the circle and its radius are called the circumcenter and the circumradius respectively. Other names for these quadrilaterals are concyclic quadrilateral and chordal quadrilateral, the latter since the sides of the quadrilateral are chords of the circumcircle. Usually the quadrilateral is assumed to be convex, but there are also crossed cyclic quadrilaterals. The formulas and properties given below are valid in the convex case. The word cyclic is from the Ancient Greek κύκλος (kuklos) which means "circle" or "wheel". All triangles have a circumcircle, but not all quadrilaterals do. An example of a quadrilateral that cannot be cyclic is a non-square rhombus. The section characterizations below states what necessary and sufficient conditions a quadrilateral must satisfy to have a circumcircle.

Non-Governmental Organisations and Sustainable Community Development
Alternative healthcare, community development, social justice, and education are all areas where non-governmental organisations (NGOs) are increasingly being recognised or promoted, but these efforts are hampered by government inefficiency and resource constraints. However, the statement of non-profit organisations is more complicated than simply comparing them to the government, as they may also suffer from a lack of resources and ineffective management, just like the government. Meanwhile, NGOs are generally defined by four characteristics: they are voluntary, non-partisan, non-profit, and non-criminal. According to Salamon and Anheier, seven distinct characteristics were used to categorise and differentiate NGOs. The seven characteristics are as follows: (1) formal (officially registered and governed); (2) private (having a separate organisation from the government); (3) non-profit distributing (different from the objectives of establishing a business organisation); (4) self-governing (privately managed); (5) voluntary (worked voluntarily); (6) non-religious (not motivated by preaching); and (7) non-political (not involved in promoting candidates in elections). These characteristics are particularly useful for identifying and differentiating NGOs from other organisations.
