Energy captured in a potential well is unable to convert to another type of energy (kinetic energy in the case of a gravitational potential well) because it is capt ...

Solitary Confinement
Solitary confinement is a form of imprisonment in which the inmate lives in a single cell with little or no meaningful contact with other people. A prison may enforce stricter measures to control contraband on a solitary prisoner and use additional security equipment in comparison to the general population. Solitary confinement is a punitive tool within the prison system to discipline or separate disruptive prison inmates who are security risks to other inmates, the prison staff, or the prison itself. However, solitary confinement is also used to protect inmates whose safety is threatened by other inmates by separating them from the general population. In a 2017 review, "a robust scientific literature has established the negative psychological effects of solitary confinement", leading to "an emerging consensus among correctional as well as professional, mental health, legal, and human rights organizations to drastically limit the use of solitary confinement." The United Nations ...

Color Confinement
In quantum chromodynamics (QCD), color confinement, often simply called confinement, is the phenomenon that color-charged particles (such as quarks and gluons) cannot be isolated, and therefore cannot be directly observed in normal conditions below the Hagedorn temperature of approximately 2 terakelvin (corresponding to energies of approximately 130–140 MeV per particle). Quarks and gluons must clump together to form hadrons. The two main types of hadron are the mesons (one quark, one antiquark) and the baryons (three quarks). In addition, colorless glueballs formed only of gluons are also consistent with confinement, though difficult to identify experimentally. Quarks and gluons cannot be separated from their parent hadron without producing new hadrons. Origin There is not yet an analytic proof of color confinement in any non-abelian gauge theory. The phenomenon can be understood qualitatively by noting that the force-carrying gluons of QCD have color charge, unlike the p ...

Childbirth
Childbirth, also known as labour and delivery, is the ending of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. In 2019, there were about 140.11 million births globally. In the developed countries, most deliveries occur in hospitals, while in the developing countries most are home births. The most common childbirth method worldwide is vaginal delivery. It involves four stages of labour: the shortening and opening of the cervix during the first stage, descent and birth of the baby during the second, the delivery of the placenta during the third, and the recovery of the mother and infant during the fourth stage, which is referred to as the postpartum. The first stage is characterized by abdominal cramping or back pain that typically lasts half a minute and occurs every 10 to 30 minutes. Contractions gradually becomes stronger and closer together. Since the pain of childbirth correlates with contractions ...

Postpartum Confinement
Postpartum confinement is a traditional practice following childbirth. Those who follow these customs typically begin immediately after the birth, and the seclusion or special treatment lasts for a culturally variable length: typically for one month or 30 days, up to 40 days, two months, or 100 days. This postnatal recuperation can include care practices in regards of "traditional health beliefs, taboos, rituals, and proscriptions." The practice used to be known as "lying-in", which, as the term suggests, centres around bed rest. In some cultures it may be connected to taboos concerning impurity after childbirth. Overview Postpartum confinement refers both to the mother and the baby. Human newborns are so underdeveloped that pediatricians such as Harvey Karp refer to the first three months as the "fourth trimester". The weeks of rest while the mother heals also protect the infant as it adjusts to the world, and both learn the skills of breastfeeding. Almost all countries have ...

Thermonuclear Fusion
Thermonuclear fusion is the process of atomic nuclei combining or “fusing” using high temperatures to drive them close enough together for this to become possible. There are two forms of thermonuclear fusion: ''uncontrolled'', in which the resulting energy is released in an uncontrolled manner, as it is in thermonuclear weapons ("hydrogen bombs") and in most stars; and ''controlled'', where the fusion reactions take place in an environment allowing some or all of the energy released to be harnessed for constructive purposes. Temperature requirements Temperature is a measure of the average kinetic energy of particles, so by heating the material it will gain energy. After reaching sufficient temperature, given by the Lawson criterion, the energy of accidental collisions within the plasma is high enough to overcome the Coulomb barrier and the particles may fuse together. In a deuterium–tritium fusion reaction, for example, the energy necessary to overcome the Coulomb barrie ...

Confined Liquid
In condensed matter physics, a confined liquid is a liquid that is subject to geometric constraints on a nanoscopic scale so that most molecules are close enough to an interface to sense some difference from standard bulk liquid conditions. Typical examples are liquids in porous media, gels, or bound in solvation shells. Confinement regularly prevents crystallization, which enables liquids to be supercooled below their homeogenous nucleation temperature even if this is impossible in the bulk state. This holds in particular for water Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a ..., which is by far the most studied confined liquid. Liquids under sub-millimeter confinement (e.g. in the gap between rigid walls) exhibit a nearly solid-like mechanical response and possess a surprisin ...

Civil Confinement
Some jurisdictions may commit certain types of dangerous sex offenders to state-run detention facilities following the completion of their sentence if that person has a "mental abnormality" or personality disorder that makes the person likely to engage in sexual offenses if not confined in a secure facility. In the United States, twenty states, the federal government, and the District of Columbia have a version of these commitment laws, which are referred to as "Sexually Violent Predator" (SVP) or "Sexually Dangerous Persons" laws. Generally speaking, SVP laws have three elements: (1) That the person has been convicted of a sexually violent offense (a term that is defined applicable statutes) (2) That the person suffers from a mental abnormality and/or personality disorder, which causes him/her serious difficulty controlling his/her sexually violent behavior. (3) That this mental abnormality and/or personality disorder makes the person likely to engage in predatory acts of sexua ...

Home Care
Homecare (also spelled as home care) is health care or supportive care provided by a professional caregiver in the individual home where the patient or client is living, as opposed to care provided in group accommodations like clinics or nursing home. Homecare is also known as domiciliary care, social care or in-home care. It comprises a range of activities, especially paramedical aid by nurses and assistance in daily living for ill, disabled or elderly people. Clients receiving home health care may incur lower costs, receive equal to better care, and have increased satisfaction in contrast to other settings. Occasionally, palliative and end-of-life care can be provided through home health nursing. Home health nurses may assist patients with activities of daily living (ADLs) such as bathing, toileting, and feeding, or they direct and supervise the aide in providing ADL care. Nurses keep track of vital signs, carry out physician orders, draw blood, document the tasks they perform ...
