Liquid–Liquid Phase Separation
Liquid–liquid phase separation (LLPS) is a thermodynamically-driven, reversible phenomenon consisting in de-mixing into two distinct liquid phases, with different solute concentrations.

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.)

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.

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.

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.

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.

Fungal Urinary Tract Infection
Fungal urinary tract infections (FUTI) are mainly caused by Candida species. The urine can be an important specimen for the diagnosis of this kind of clinical condition since both the presence of fungi can be identified by urine microscopy and by uroculture and the cells that promotes the immune response against this kind of infectious agent can also be observed. This entry will focus on information related to FUTI and the urinary findings that can be detected during routine urinalysis that can contribute to the identification of this clinical condition.

Sociology and History
Sociology and History as consolidated scientific and academic projects have maintained a peculiar and paradoxical relationship. The growing disciplinary and subdisciplinary specialisation of these two sciences poses relevant epistemological and methodological challenges in order to face potential situations of isolation, fragmentation and enable the apology of an interdisciplinary perspective characterised by the historicity of social structures, actions and senses.
