List of Most Successful U-boat Commanders
The list of most successful U-boat commanders contains the top-scoring German U-boat commanders in the two World Wars based on their total tonnage sunk. The tonnage figures (and sometimes the number of ships sunk) is still being debated among historians. This is often due to convoy battles at night when an attacking "wolfpack" fired torpedoes into the convoy and two (sometimes more) commanders claimed the same ship. Although post-war research has clarified most of those claims, some are still in question.

Business Engineering
Business engineering (BE) is the development and implementation of business solutions, from business model to business processes and organizational structure to information systems and information technology (cf.). Business engineering focuses on developing innovative business solutions that take a sociotechnical systems (STS) approach. The STS approach addresses an enterprise as a total system in the same manner as an airplane system or an industrial facility, since they possess a similar level of complexity. Business engineering combines knowledge in the fields of business administration, Industrial Engineering, as well as information technology and connects it to all aspects of transformation, from means of presentation to process models to cultural and political considerations (cf. Baumöl/Jung).A person is referred to as a Business Engineer when the person is a hybrid between an entrepreneur and an engineer. They must poses the understanding of how the business world operates at both macro and micro levels and be in a position to come up with solutions based on various key elements.

List of Asteroids in Astrology
Asteroids are relatively new to astrology, having only been discovered in the 19th century. However, some of them (especially the largest of them), are believed by some astrologers to influence human affairs. Still though, they are often ignored within mainstream systems of astrology, especially in more traditional astrology systems like Vedic astrology or Hellenistic astrology. Their use has become significant to a few Western astrologers yet still only a minority of astrologers use the asteroids in chart interpretation.

German Question
"The German Question" was a debate in the 19th century, especially during the Revolutions of 1848, over the best way to achieve a unification of all or most lands inhabited by Germans. From 1815 to 1866, about 37 independent German-speaking states existed within the German Confederation. The Großdeutsche Lösung ("Greater German solution") favored unifying all German-speaking peoples under one state, and was promoted by the Austrian Empire and its supporters. The Kleindeutsche Lösung ("Little German solution") sought only to unify the northern German states and did not include any part of Austria (either its German-inhabited areas or its areas dominated by other ethnic groups); this proposal was favored by the Kingdom of Prussia. The solutions are also referred to by the names of the states they proposed to create, Kleindeutschland and Großdeutschland ("Little Germany" and "Greater Germany"). Both movements were part of a growing German nationalism. They also drew upon similar contemporary efforts to create a unified nation state of people who shared a common ethnicity and language, such as the unification of Italy by the House of Savoy and the Serbian Revolution. During the Cold War, the term also referred to the matters pertaining to the division, and re-unification, of Germany.

Bell Peppers (Capsicum annum L.)
The bell pepper is highly consumed worldwide due to its exotic colors (green, red, yellow, orange, and purple), flavor, and nutritional value. However, after processing bell pepper products, waste remains (seeds, peel, stem, and leaves), representing desirable raw material to obtain phytochemical compounds. They contain diverse bioactive compounds with interesting biological activities (in vivo and in vitro) and applications.

WikiLeaks
WikiLeaks (/ˈwɪkiliːks/) is an international non-profit organisation that publishes news leaks and classified media provided by anonymous sources. Its website, initiated in 2006 in Iceland by the organisation Sunshine Press, stated in 2015 that it had released online 10 million documents in its first 10 years. Julian Assange, an Australian Internet activist, is generally described as its founder and director. Since September 2018, Kristinn Hrafnsson has served as its editor-in-chief. WikiLeaks has variously described itself as an organization of journalists, political activists, mathematicians, and start-up company technologists, an intermediary between sources and journalists, an advocacy group for sources, and a public intelligence agency. The group has released a number of prominent document caches that exposed serious violations of human rights and civil liberties to the US and international public. Early releases included documentation of equipment expenditures and holdings in the Afghanistan war, a report about a corruption investigation in Kenya, and an operating procedures manual for the U.S. prison at Guantanamo Bay, Cuba. In April 2010, WikiLeaks released the Collateral Murder footage from the 12 July 2007 Baghdad airstrike in which Iraqi Reuters journalists were among several civilians killed. Other releases in 2010 included the Afghan War Diary and the "Iraq War Logs". The latter release allowed the mapping of 109,032 deaths in "significant" attacks by insurgents in Iraq that had been reported to Multi-National Force – Iraq, including about 15,000 that had not been previously published. In 2010, WikiLeaks also released classified diplomatic cables that had been sent to the US State Department. In April 2011, WikiLeaks began publishing 779 secret files relating to prisoners detained in the Guantanamo Bay detention camp. In 2012, WikiLeaks released the "Syria Files," over two million emails sent by Syrian politicians, corporations and government ministries. In 2015, WikiLeaks published Saudi Arabian diplomatic cables, documents detailing spying by the U.S. National Security Agency on successive French presidents, and the intellectual property chapter of the Trans-Pacific Partnership, a controversial international trade agreement which had been negotiated in secret. During the 2016 U.S. presidential election campaign, WikiLeaks released emails and other documents from the Democratic National Committee and from Hillary Clinton's campaign manager, John Podesta, showing that the party's national committee favoured Clinton over her rival Bernie Sanders in the primaries, leading to the resignation of DNC chairwoman Debbie Wasserman Schultz and an apology to Sanders from the DNC. These releases caused significant harm to the Clinton campaign, and have been attributed as a potential contributing factor to her loss in the general election against Donald Trump. The U.S. intelligence community expressed "high confidence" that the leaked emails had been hacked by Russia and supplied to WikiLeaks. WikiLeaks said that the source of the documents was not Russia or any other state. During the campaign, WikiLeaks promoted conspiracy theories about Hillary Clinton and the Democratic Party. In 2016, WikiLeaks released nearly 300,000 emails it described as coming from Turkey's ruling Justice and Development Party, later found to be taken from public mailing archives, and rereleased over 50,000 emails from the Turkish Minister of Energy and Natural Resources. In 2017, WikiLeaks published internal CIA documents describing tools used by the agency to hack devices including mobile phones and routers. In 2019, WikiLeaks published over 30,000 files as part of the Fishrot Files, exposing corruption at Samherji, a multinational fishing company based in Iceland. In October 2021, WikiLeaks' secure chat stopped working and in February 2022 their submission system and email server went offline. The organisation has been criticised for inadequately curating its content and violating the personal privacy of individuals. WikiLeaks has, for instance, revealed Social Security numbers, medical information, credit card numbers and details of suicide attempts.

ICO (File Format)
The ICO file format is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately. In Windows, all executables that display an icon to the user, on the desktop, in the Start Menu, or in Windows Explorer, must carry the icon in ICO format. The CUR file format is an almost identical image file format for non-animated cursors in Microsoft Windows. The only differences between these two file formats are the bytes used to identify them and the addition of a hotspot in the CUR format header; the hotspot is defined as the pixel offset (in x,y coordinates) from the top-left corner of the cursor image where the user is actually pointing the mouse.

Islam in Albania (1913–1944)
Islam in Albania (1913–1944) was characterised by an increasing secularisation of Albanian society which had begun with Albanian Independence in 1912 carrying on influences from the Albanian National Awakening. During the interwar period, new local Muslim institutions such as the Muslim Community of Albania arose that severed ties with the Ottoman Caliphate and placed a focus on localising Islam in Albania. The Albanian state also played a significant role in that process through state interference and pressuring the uptake of reforms by those institutions and wider Muslim society. Measures that were adopted were banning the veil and others which were interpreted as modernising Albania. These events caused tensions within parts of Muslim society between conservatives and those who viewed themselves as progressives which caused discussions and reflections about the future role of Islam in Albania and Albanian identity. The interwar era also saw Sufi Islam expand in Albania with various orders gaining new adherents with the largest, the Bektashi Order moving its world headquarters to Albania.

Home Economics
Home economics, or family and consumer sciences, is a subject concerning human development, personal and family finances, consumer issues, housing and interior design, nutrition and food preparation, as well as textiles and apparel. Home economics courses are offered around the world and across multiple educational levels. Internationally, it is coordinated by the International Federation for Home Economics. Historically, the purpose of these courses was to professionalize housework, to provide intellectual fulfillment for women, and to emphasize the value of "women's work" in society and to prepare them for the traditional roles of sexes. However, it has since evolved into family and consumer sciences to cover additional subject matter outside of just home life and wellness. Family and consumer sciences are taught as an elective or required course in secondary education, as a continuing education course in institutions, and at the primary level.   Beginning as home economics in the United States, the course was a key part of the education system for teaching one the art of taking care of a household. In the 19th and early 20th century, it was a woman-dominated course, teaching women to be homemakers and efficient household managers. The American Association of Family and Consumer Sciences was created as an answer to more Americans desiring youth to learn vocational skills. Politics played a role in home economics education, and it wasn’t until later in the century that the course shifted from being woman-dominated to now required for both sexes.   Now family and consumer science have been included in the broader subject of Career Technical Education, a program that teaches skilled trades, applied sciences, modern technologies, and career preparation. Despite the subjects over the past century, there has been a major decline in home economics courses offered by educational institutions.

Maternal Night-Time Eating During Pregnancy
This narrative review focuses on the contributing factors and health implications of night eating during pregnancy, based on evidence from cross-sectional studies and longitudinal cohorts. The modern lifestyle and presence of pregnancy symptoms contribute to night eating during pregnancy, which is likely to coexist and interact with multiple undesirable lifestyle behaviors. Unfavorable nutritional characteristics associated with night eating have the potential to induce aberrant circadian rhythms in pregnant women, resulting in adverse metabolic and pregnancy outcomes.

Transfersomes
Transfersomes are elastic in nature, which can deform and squeeze themselves as an intact vesicle through narrow pores that are significantly smaller than its size. Encapsulating the drugs in transfersomes are one of the potential approaches to overcome the barrier function of the skin’s outermost layer. They have a bilayered structure that facilitates the encapsulation of lipophilic and hydrophilic, as well as amphiphilic, drug with higher permeation efficiencies compared to conventional liposomes.

Cannabis sativa L.
Hemp (Cannabis sativa L.) is an ancient, widespread, multipurpose crop cultivated all over the world, all parts of which can be potentially usable for the production of many different commodities with industrial interest. It is one of the oldest cultivated crops and until the first half of the 1900s, it was widely grown essentially as a fibre crop. Declining the demand for natural fibre consequential to the upper hand of synthetic fibre, and competition from other plant fibre sources led to reduce the demand for hemp. In addition, the use of some narcotic strains containing high and unhealthy level (>0.3%) of the only one psychoactive substance, namely the cannabinoid delta-9 tetrahydrocannabinol (THC), led to the crop's prohibition during much of the 20th century. The clarification of the genetics and the biosynthetic pathway of the cannabinoids has been essential to identify three main different genotypes and the related chemical phenotypes of hemp plants, differing in the content of the two main hemp cannabinoids, THC and cannabidiol (CBD). Among these, the chemical phenotype commonly named "industrial hemp" includes hemp varieties which contain <0.3% or 0.2% of THC level that makes them unsuitable for narcotic purposes, but very useful for many other industrial applications. Therefore, from a legislative point of view, the main western countries such as United States, Canada, and European Union after a prohibition period, from the last decade of 1900s, have reintroduced and restored the industrial hemp cultivation.

Pentium FDIV Bug
The Pentium FDIV bug is a hardware bug affecting the floating point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor might return incorrect binary floating point results when dividing a number. The bug was discovered in 1994 by Professor Thomas R. Nicely at Lynchburg College. Intel attributed the error to missing entries in the lookup table used by the floating-point division circuitry. The severity of the FDIV bug is debated. Though rarely encountered by most users (Byte magazine estimated that 1 in 9 billion floating point divides with random parameters would produce inaccurate results), both the flaw and Intel's initial handling of the matter were heavily criticized by the tech community. In December 1994, Intel recalled the defective processors. In January 1995, Intel announced "a pre-tax charge of $475 million against earnings, ostensibly the total cost associated with replacement of the flawed processors."

Mass Transfer in Packed-Bed Columns
This review provides a thorough analysis of the most famous mass transfer models for random and structured packed-bed columns used in absorption/stripping and distillation processes, providing an overview of the equations to calculate the mass transfer parameters, i.e.: gas-side coefficient per unit surface ky [kmol·m-2·s-1], liquid-side coefficient per unit surface kx [kmol·m-2·s-1], interfacial packing area ae [m2·m-3], which constitute the ingredients to assess the mass transfer rate of packed-bed columns. This work also provides the ranges of model validity and applicability together with their main pros and cons and the criticalities behind these models, which mostly rely on the assessment of fluid-dynamics parameters such as liquid film thickness, liquid hold-up and interfacial area, or the real liquid paths or any mal-distributions flow.

Mediterranean Climate
A Mediterranean climate /ˌmɛdɪtəˈreɪniən/ or dry summer climate is characterized by dry summers and mild, wet winters. The climate receives its name from the Mediterranean Basin, where this climate type is most common. Mediterranean climate zones are typically located along the western sides of continents, between roughly 30 and 45 degrees north and south of the equator. The main cause of Mediterranean, or dry summer climate, is the subtropical ridge which extends northwards during the summer and migrates south during the winter due to increasing north-south temperature differences. The resulting vegetation of Mediterranean climates are the garrigue or maquis in the Mediterranean Basin, the chaparral in California, the fynbos in South Africa, the mallee in Australia, and the matorral in Chile. Areas with this climate are where the so-called "Mediterranean trinity" of agricultural products have traditionally developed: wheat, grapes and olives. Most historic cities of the Mediterranean basin lie within Mediterranean climatic zones, including Algiers, Athens, Barcelona, Beirut, İzmir, Jerusalem, Marseille, Naples, Rome, Tunis, Valencia, and Valletta. Major cities with Mediterranean climates outside of the Mediterranean basin include Adelaide, Cape Town, Casablanca, Dushanbe, Lisbon, Los Angeles , Perth, Porto, Sacramento, San Diego, San Francisco , San Jose, CA, Santiago, Tashkent and Victoria.

Democratic Socialism
Democratic socialism is a political philosophy that supports political democracy and some form of a socially owned economy,({{{1}}}, {{{2}}}) with a particular emphasis on economic democracy, workplace democracy, and workers' self-management within a market socialist economy, or an alternative form of decentralised planned socialist economy. Democratic socialists argue that capitalism is inherently incompatible with the values of freedom, equality, and solidarity and that these ideals can only be achieved through the realisation of a socialist society. Although most democratic socialists seek a gradual transition to socialism,({{{1}}}, {{{2}}}) democratic socialism can support either revolutionary or reformist politics as means to establish socialism.({{{1}}}, {{{2}}}) Democratic socialism was popularized by socialists who were opposed to the backsliding towards a one-party state in the Soviet Union and other nations during the 20th century.({{{1}}}, {{{2}}}) The history of democratic socialism can be traced back to 19th-century socialist thinkers across Europe and the Chartist movement in Britain, which somewhat differed in their goals but shared a common demand of democratic decision making and public ownership of the means of production, and viewed these as fundamental characteristics of the society they advocated for. In the late 19th to the early 20th century, democratic socialism was also heavily influenced by the gradualist form of socialism promoted by the British Fabian Society and Eduard Bernstein's evolutionary socialism in Germany.({{{1}}}, {{{2}}}) Democratic socialism is what most socialists understand by the concept of socialism;({{{1}}}, {{{2}}}) it may be a very broad (socialists who reject a one-party Marxist–Leninist state)({{{1}}}, {{{2}}}) or more limited concept (post-war social democracy).({{{1}}}, {{{2}}}) As a broad movement, it includes forms of libertarian socialism,({{{1}}}, {{{2}}}) market socialism,({{{1}}}, {{{2}}}) reformist socialism, and revolutionary socialism,({{{1}}}, {{{2}}}) as well as ethical socialism,({{{1}}}, {{{2}}}) liberal socialism,({{{1}}}, {{{2}}}) social democracy,({{{1}}}, {{{2}}}) and some forms of state socialism and utopian socialism, all of which share commitment to democracy.({{{1}}}, {{{2}}}) Democratic socialism is contrasted with Marxism–Leninism, which opponents often perceive as being authoritarian and undemocratic in practice.({{{1}}}, {{{2}}}) Democratic socialists oppose the Stalinist political system and the Soviet-type economic planning system, rejecting as their form of governance the administrative-command system that formed in the Soviet Union and other Marxist–Leninist states during the 20th century. Democratic socialism is also distinguished from Third Way social democracy[nb 1] on the basis that democratic socialists are committed to systemic transformation of the economy from capitalism to socialism.[nb 2] While having socialism as a long-term goal,({{{1}}}, {{{2}}}) some moderate democratic socialists are more concerned about curbing capitalism's excesses, and are supportive of progressive reforms to humanise it in the present day,({{{1}}}, {{{2}}}) while other democratic socialists believe that economic interventionism and similar policy reforms aimed at addressing social inequalities and suppressing the economic contradictions of capitalism would only exacerbate the contradictions,({{{1}}}, {{{2}}}) causing them to emerge elsewhere under a different guise.({{{1}}}, {{{2}}}) Those democratic socialists believe that the fundamental issues with capitalism are systemic in nature, and can only be resolved by replacing the capitalist mode of production with the socialist mode of production through the replacement of private ownership with collective ownership of the means of production, and extending democracy to the economic sphere in the form of industrial democracy.({{{1}}}, {{{2}}}) The main criticism of democratic socialism is focused on the compatibility of democracy and socialism. Several academics and political commentators tend to distinguish between authoritarian socialism and democratic socialism as a political ideology, with the first representing the Soviet Bloc, and the latter representing the democratic socialist parties in the Western Bloc countries that have been democratically elected in countries such as Britain, France, and Sweden, among others.({{{1}}}, {{{2}}}) However, following the end of the Cold War, many of these countries have moved away from socialism as a neoliberal consensus replaced the social democratic consensus in the advanced capitalist world.
