Water Mills
The reuse of built agricultural/industrial heritage has been a common practice worldwide. These structures represent excellent symbols of the great agricultural/industrial past. These agricultural/hydro-technologies also serve as monuments of socio-cultural identities, especially in rural areas and on small farms. One example of a successful application of agricultural technologies for small farms is the water mill. By harnessing the water energy, they were used for traditional flour and other goods production (e.g., olive oil) and works requiring energy, with the main role in the evolution of the traditional/cultural landscape. Water mills have been used to drive a mechanical process of milling, hammering, and rolling and are a portion of the agricultural, cultural, and industrial heritage.

History of Telecommunication
The history of telecommunication began with the use of smoke signals and drums in Africa, the Americas and parts of Asia. In the 1790s, the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication.

Malthusianism
Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe (also known as a Malthusian trap, population trap, Malthusian check, Malthusian crisis, Malthusian spectre, or Malthusian crunch) occurs when population growth outpaces agricultural production, causing famine or war, resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population (quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks) to "correct" back to a lower, more easily sustainable level. Malthusianism has been linked to a variety of political and social movements, but almost always refers to advocates of population control. These concepts derive from the political and economic thought of the Reverend Thomas Robert Malthus, as laid out in his 1798 writings, An Essay on the Principle of Population. Malthus suggested that while technological advances could increase a society's supply of resources, such as food, and thereby improve the standard of living, the resource abundance would enable population growth, which would eventually bring the per capita supply of resources back to its original level. Some economists contend that since the industrial revolution, mankind has broken out of the trap. Others argue that the continuation of extreme poverty indicates that the Malthusian trap continues to operate. Others further argue that due to lack of food availability coupled with excessive pollution, developing countries show more evidence of the trap. A similar, more modern concept, is that of human overpopulation. Neo-Malthusianism is the advocacy of human population planning to ensure resources and environmental integrities for current and future human populations as well as for other species. In Britain the term 'Malthusian' can also refer more specifically to arguments made in favour of preventive birth control, hence organizations such as the Malthusian League. Neo-Malthusians differ from Malthus's theories mainly in their support for the use of contraception. Malthus, a devout Christian, believed that "self-control" (i.e., abstinence) was preferable to artificial birth control. He also worried that the effect of contraceptive use would be too powerful in curbing growth, conflicting with the common 18th century perspective (to which Malthus himself adhered) that a steadily growing population remained a necessary factor in the continuing "progress of society", generally. Modern neo-Malthusians are generally more concerned than Malthus with environmental degradation and catastrophic famine than with poverty. Malthusianism has attracted criticism from diverse schools of thought, including Marxists and socialists, libertarians and free market enthusiasts, feminists and human rights advocates, characterising it as excessively pessimistic, misanthropic or inhuman. Many critics believe Malthusianism has been discredited since the publication of Principle of Population, often citing advances in agricultural techniques and modern reductions in human fertility. Many modern proponents believe that the basic concept of population growth eventually outstripping resources is still fundamentally valid, and that positive checks are still likely to occur in humanity's future if no action is taken to intentionally curb population growth. In spite of the variety of criticisms against it, the Malthusian argument remains a major discourse based on which national and international environmental regulations are promoted.

TCP-based Congestion Control Algorithms
In today’s data networks, the main protocol used to ensure reliable communications is the transmission control protocol (TCP). The TCP performance is largely determined by the used congestion control (CC) algorithm, which main purpose is to avoid the congestion of the network that can be caused by a large burst of data traffic. TCP CC algorithms have evolved over the past three decades and a large number of CC algorithm variations have been developed to accommodate various communication network environments. Considering the importance of CC in communication networks, the fundamentals of the TCP as the main transport layer protocol and CC process have been explained in detail. Also, an encyclopedic overview of the most popular single-flow and multi-flow TCP CC algorithms with corresponding alternatives has been present. Future directions in the possible improvement of CC algorithms for implementation in complex heterogeneous networks composed of wired and wireless elements are lastly discussed in this encyclopedic work.

Solaris (Operating System)
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. It superseded the company's earlier SunOS in 1993. In 2010, after the Sun acquisition by Oracle, it was renamed Oracle Solaris. Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris is registered as compliant with the Single UNIX Specification. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. With OpenSolaris, Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. In August 2010, Oracle discontinued providing public updates to the source code of the Solaris kernel, effectively turning Solaris 11 back into a closed source proprietary operating system. Following that, OpenSolaris was forked as illumos and is alive through several illumos distributions. In 2011, the Solaris 11 kernel source code leaked to BitTorrent. However, through the Oracle Technology Network (OTN), industry partners can still gain access to the in-development Solaris source code. Solaris is developed under a proprietary development model, and only the source for open-source components of Solaris 11 is available for download from Oracle.

Housewife
A housewife (also known as a homemaker) is a woman whose work is running or managing her family's home—caring for her children; buying, cooking, and storing food for the family; buying goods that the family needs for everyday life; housekeeping, cleaning and maintaining the home; and making, buying and/or mending clothes for the family—and who is not employed outside the home (a career woman). A housewife who has children may be called a stay-at-home mother or mom. Webster's Dictionary defines a housewife as a married woman who is in charge of her household. The British Chambers's Twentieth Century Dictionary (1901) defines a housewife as "the mistress of a household; a female domestic manager; a pocket sewing kit". (A small sewing kit is sometimes called a housewife or hussif.)

Shaft Mining
Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft. Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called Raises. A shaft may be either vertical or inclined (between 45 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts. Shaft sinking is one of the most difficult of all development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Historically mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada , Germany and South Africa .

Power (Social and Political)
In social science and politics, power is the capacity of an individual to influence the actions, beliefs, or conduct (behaviour) of others. The term "authority" is often used for power that is perceived as legitimate by the social structure. Power can be seen as evil or unjust. However, power can also be seen as good and as something inherited or given for exercising humanistic objectives that will help, move, and empower others as well. In general, it is derived by the factors of interdependence between two entities and the environment. In business, the ethical instrumentality of power is achievement, and as such it is a zero-sum game. In simple terms it can be expressed as being "upward" or "downward". With downward power, a company's superior influences subordinates for attaining organizational goals. When a company exerts upward power, it is the subordinates who influence the decisions of their leader or leaders. The use of power need not involve force or the threat of force (coercion). An example of using power without oppression is the concept "soft power," as compared to hard power. Much of the recent sociological debate about power revolves around the issue of its means to enable – in other words, power as a means to make social actions possible as much as it may constrain or prevent them.

Gender Fair Language
Gender fair language (GFL) is language used with the intention of reducing gender bias in one's mental representation, or mental understanding of an idea. Gender fair language includes gender-neutral (English singular they) and gender-inclusive language (English he or she). Feminization strategies of gender fair language use gender-inclusive language. Neutralization strategies of gender fair language use gender-neutral language. Some languages however are genderless rendering such strategies superfluous. Gender fair language focuses on grammatical gender, where gender is marked grammatically in the language. Gender fair language does not interact with gender noun classes, in which some languages categorize nouns. Gender fair language concerns grammatical gender marking on nouns that reference humans, where the gender marking is in accordance with the gender of the human. Gender marking occurs the most in gendered languages, like German, Spanish, and French, where all nouns are grammatically gendered. In these languages, gender fair language generally applies to nouns, pronouns, role nouns (e.g. German der Lehrer "teacher; m."), and possessive pronouns. Grammatical gender is also marked to a lesser extent in natural gender languages, like English and Swedish, in which animate referents are grammatically gendered according to their intrinsic gender. In these languages, gender fair language generally applies only to pronouns and possessive pronouns. Every language has its own method for grammatical gender marking, and thus gender fair language applies differently to each language to match its need.

Polarization (Politics)
Template:Globalize/US In politics, polarization (or polarisation) can refer to the divergence of political attitudes to ideological extremes. Almost all discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. When polarization occurs in a two-party system, like the United States , moderate voices often lose power and influence.

Uncompetitive Inhibitor
Uncompetitive inhibition, also known as anti-competitive inhibition, takes place when an enzyme inhibitor binds only to the complex formed between the enzyme and the substrate (the E-S complex). Uncompetitive inhibition typically occurs in reactions with two or more substrates or products. While uncompetitive inhibition requires that an enzyme-substrate complex must be formed, non-competitive inhibition can occur with or without the substrate present. Uncompetitive inhibition is distinguished from competitive inhibition by two observations: first uncompetitive inhibition cannot be reversed by increasing [S] and second, as shown, the Lineweaver–Burk plot yields parallel rather than intersecting lines. This behavior is found in the inhibition of acetylcholinesterase by tertiary amines (R3N). Such compounds bind to the enzyme in its various forms, but the acyl-intermediate-amine complex cannot break down into enzyme plus product.

Digitalisation of organisations and COVID-19
The COVID-19 pandemic caused profound shifts in the functioning of organisations, with the increased mobilisation of the implementation of digitalisation processes in the activities of the members of these coordinated collective units. In this perspective, based on our academic experience and recent literature, this paper offers some dimensions that seem to us relevant to ponder with special urgency, and that will shape both organisations in the near future and an organisational culture that is, in many cases, renewed.

Folk Dance
A folk dance is a dance developed by people that reflect the life of the people of a certain country or region. Not all ethnic dances are folk dances. For example, ritual dances or dances of ritual origin are not considered to be folk dances. Ritual dances are usually called "Religious dances" because of their purpose. The terms "ethnic" and "traditional" are used when it is required to emphasize the cultural roots of the dance. In this sense, nearly all folk dances are ethnic ones. If some dances, such as polka, cross ethnic boundaries and even cross the boundary between "folk" and "ballroom dance", ethnic differences are often considerable enough to mention.
