Sources Acetylene is a hot-burning fuel used in welding torches.. Cicutoxin is a toxin found in water hemlock flowers. The simplest of the  alkyne  series, it is commonly called acetyline. It is often used as a fuel for welding torches sinces it produces a large amount of heat upon combustion. Oxyacetylene welding uses compressed acetylene and compressed oxygen for mixing in the torch flame . An exhaustive list would be hard to make, but if you put calcium carbide in water, the gas that comes off is an alkyne (ethyne, more commonly called acetylene) C2H2

Alkynes in nature and medicine According to Ferdinand Bohlmann, the first naturally occurring acetylenic compound, dehydromatricaria ester, was isolated from an Artemisia  species in 1826 . Polyynes, a subset of this class of natural products, have been isolated from a wide variety of plant species, cultures of higher fungi, bacteria, marine sponges, and corals.  Some acids like  tariric acid  contains an alkyne group. Diynes and triynes, species with the linkage RC ≡ C-C ≡ CR' and RC ≡ C-C ≡ C-C ≡ CR' respectively, occur in certain plants ( Ichthyothere , Chrysanthemum ,  Cicuta ,  Oenanthe  and other members of the  Asteraceae  and  Apiaceae  families).  Some examples are  cicutoxin , oenanthotoxin ,  falcarinol  and  carotatoxin . These compounds are highly bioactive, e.g. as  nematocides .  1-Phenylhepta-1,3,5-triyne is illustrative of a naturally occurring triyne. Alkynes occur in some pharmaceuticals, including the contraceptive  norethynodrel .  A car

In 1843, Dorothea Dix submitted a Memorial to the Legislature of Massachusetts, describing the abusive treatment and horrible conditions received by the mentally ill patients in jails, cages, and almshouses. She revealed in her Memorial: “I proceed, gentlemen, briefly to call your attention to the present state of insane persons confined within this Commonwealth, in cages, closets, cellars, stalls, pens! Chained, naked, beaten with rods, and lashed into obedience. . . .” Many asylums were built in that period, with high fences or walls separating the patients from other community members and strict rules regarding the entrance and exit. In those asylums, traditional treatments were well implemented: drugs were not used as a cure for a disease, but a way to reset equilibrium in a person’s body, along with other essential elements such as healthy diets, fresh air, middle class culture, and the visits by their neighboring residents. In 1866, a recommendation came to the New York State L

Therapies Activity therapies Activity therapies, also called recreation therapy and occupational therapy, promote healing through active engagement. Making crafts can be a part of occupational therapy. Walks can be a part of recreation therapy. Expressive therapies Expressive therapies are a form of psychotherapy that involves the arts or art-making. These therapies include music therapy, art therapy, dance therapy, drama therapy, and poetry therapy. Alternative therapies Alternative therapy is a branch of alternative medicine, which includes a large number of therapies imported from other cultures. It also includes a number of new medicines that have not yet passed through the process of scientific review. Alternative therapies include traditional medicine, prayer, yoga, traditional Chinese medicine, Ayurvedic medicine, homeopathy, hypnotherapy, and more. Group therapy Group therapy involves any type of therapy that takes place in a setting involving multiple people. I

Evidence from the World Health Organization suggests that nearly half the world's population are affected by mental illness with an impact on their self-esteem, relationships and ability to function in everyday life.An individual's emotional health can also impact physical health and poor mental health can lead to problems such as substance abuse.Maintaining good mental health is crucial to living a long and healthy life. Good mental health can enhance one’s life, while poor mental health can prevent someone from living an enriching life. According to Richards, Campania, & Muse-Burke (2010) “There is growing evidence that is showing emotional abilities are associated with prosocial behaviors such as stress management and physical health” (2010). It was also concluded in their research that people who lack emotional expression are inclined to anti-social behaviors. These behaviors are a direct reflection of their mental health. Self-destructive acts may take place to suppr

In the mid-19th century, William Sweetzer was the first to clearly define the term "mental hygiene", which can be seen as the precursor to contemporary approaches to work on promoting positive mental health. Isaac Ray, one of thirteen founders of the American Psychiatric Association, further defined mental hygiene as an art to preserve the mind against incidents and influences which would inhibit or destroy its energy, quality or development. An important figure to "mental hygiene", would be Dorothea Dix (1802–1887), a school teacher, who had campaigned her whole life in order to help those suffering of a mental illness, and to bring to light the deplorable conditions into which they were put. This was known as the "mental hygiene movement".Before this movement, it was not uncommon that people affected by mental illness in the 19th century would be considerably neglected, often left alone in deplorable conditions, barely even having sufficient clothing

Mental health  Describes a level of psychological well-being, or an absence of a mental disorder. From the perspective of 'positive psychology' or 'holism', mental health may include an individual's ability to enjoy life, and create a balance between life activities and efforts to achieve psychological resilience. Mental health can also be defined as an expression of emotions, and as signifying a successful adaptation to a range of demands. The World Health Organization defines mental health as "a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community". It was previously stated that there was no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. There
