Nitrox refers to any gas mixture composed of nitrogen and oxygen. This includes atmospheric air, 78% nitrogen, 21% oxygen, 1% other gases argon. In the usual application, underwater diving, nitrox is distinguished from air and handled differently; the most common use of nitrox mixtures containing oxygen in higher proportions than atmospheric air is in scuba diving, where the reduced partial pressure of nitrogen is advantageous in reducing nitrogen uptake in the body's tissues, thereby extending the practicable underwater dive time by reducing the decompression requirement, or reducing the risk of decompression sickness. Nitrox is used to a lesser extent in surface-supplied diving, as these advantages are reduced by the more complex logistical requirements for nitrox compared to the use of simple low-pressure compressors for breathing gas supply. Nitrox can be used in hyperbaric treatment of decompression illness at pressures where pure oxygen would be hazardous. Nitrox is not a safer gas than compressed air in all respects.

Though not referred to as nitrox, an oxygen-enriched air mixture is provided at normal surface ambient pressure as oxygen therapy to patients with compromised respiration and circulation. Reducing the proportion of nitrogen by increasing the proportion of oxygen reduces the risk of decompression sickness for the same dive profile, or allows extended dive times without increasing the need for decompression stops for the same risk; the significant aspect of extended no-stop time when using nitrox mixtures is reduced risk in a situation where breathing gas supply is compromised, as the diver can make a direct ascent to the surface with an acceptably low risk of decompression sickness. The exact values of the extended no-stop times vary depending on the decompression model used to derive the tables, but as an approximation, it is based on the partial pressure of nitrogen at the dive depth; this principle can be used to calculate an equivalent air depth with the same partial pressure of nitrogen as the mix to be used, this depth is less than the actual dive depth for oxygen enriched mixtures.

The equivalent air depth is used with air decompression tables to calculate decompression obligation and no-stop times. The Goldman decompression model predicts a significant risk reduction by using nitrox. Controlled tests have not shown breathing nitrox to reduce the effects of nitrogen narcosis, as oxygen seems to have narcotic properties under pressure to nitrogen. Nonetheless, there are people in the diving community who insist that they feel reduced narcotic effects at depths breathing nitrox; this may be due to a dissociation of the behavioural effects of narcosis. Although oxygen appears chemically more narcotic at the surface, relative narcotic effects at depth have never been studied in detail, but it is known that different gases produce different narcotic effects as depth increases. Helium has no narcotic effect, but results in HPNS when breathed at high pressures, which does not happen with gases that have greater narcotic potency. However, because of risks associated with oxygen toxicity, divers do not use nitrox at greater depths where more pronounced narcosis symptoms are more to occur.

For deep diving, trimix or heliox gases are used. Diving with and handling nitrox raise a number of fatal dangers due to the high partial pressure of oxygen. Nitrox is not a deep-diving gas mixture owing to the increased proportion of oxygen, which becomes toxic when breathed at high pressure. For example, the maximum operating depth of nitrox with 36% oxygen, a popular recreational diving mix, is 29 metres to ensure a maximum ppO2 of no more than 1.4 bar. The exact value of the maximum allowed ppO2 and maximum operating depth varies depending on factors such as the training agency, the type of dive, the breathing equipment and the level of surface support, with professional divers sometimes being allowed to breathe higher ppO2 than those recommended to recreational divers. To dive safely with nitrox, the diver must learn good buoyancy control, a vital part of scuba diving in its own right, a disciplined approach to preparing and executing a dive to ensure that the ppO2 is known, the maximum operating depth is not exceeded.

Many dive shops, dive operators, gas blenders require the diver to present a nitrox certification card before selling nitrox to divers. Some training agencies, such as PADI and Technical Diving International, teach the use of two depth limits to protect against oxygen toxicity; the shallower depth is called the "maximum operating depth" and is reached when the partial pressure of oxygen in the breathing gas reaches 1.4 bar. The deeper depth, called the "contingency depth", is reached when the partial pressure reaches 1.6 bar. Diving at or beyond this level exposes the diver to a greater risk of central nervous system oxygen toxicity; this can be dangerous since its onset is without warning and can lead to drowning, as the regulator may be spat out during convulsions, which occur in conjunction with sudden unconsciousness. Divers trained to use nitrox may memorise the acronym VENTID-C or sometimes ConVENTID, (which stands for Vision, Nausea, Irritability and Con

Aboriginal Housing Victoria is a not-for-profit, registered community housing agency and is the largest Aboriginal housing organisation in the Australian state of Victoria. "Our vision is that Aboriginal Victorians are able to secure appropriate, affordable housing as a pathway to better lives and stronger communities." AHV was the first Aboriginal housing agency to be registered as a housing provider in Victoria and it is the largest in Australia, serves as an Aboriginal landlord, providing personalised, culturally sensitive services for over 4000 Aboriginal people in Victoria through more than 1500 tenancies. AHV provides housing to 4,000 low income Aboriginal and Torres Strait Islander Victorians, representing at least 8% of the Victorian Aboriginal population, in 1,525 properties across metropolitan and regional Victoria; the majority of the properties are owned by the Department of Human Services. Aboriginal and Torres Strait Islander people in need of housing can make an application to AHV, they will be placed on a waiting list until a suitable home in a preferred area becomes available.

Applicants may be considered for priority housing if they are deemed to have a more urgent need than general applicants. Tenants pay subsidised rent to AHV. AHV achieves above community housing sector standard for maintaining tenancies – 89% in 2014–15. While provision of housing is core business, the organisation works with other Aboriginal service providers to support the needs of its tenants who can have unique and complex disadvantage; the organisation believes this success is rooted in the notion that Aboriginal owned and controlled organisations are best placed to provide services for Aboriginal people, without interference or patronage from non-Aboriginal organisations or bureaucracies. But AHV is a multicultural organisation and sees its strength in the diversity of its people – both Indigenous and non-Indigenous – "working together with mutual respect and co-operation and knowledge" – Jim Berg, "More Bees With Honey –A History of the Aboriginal Housing Board of Victoria.” Until the 1950s no government housing was provided for Aboriginal people in Victoria and much of what began to be provided was inadequate, delivered under an assimilation policy that saw the dislocation of Aboriginal people from traditional lands into accommodation, unfit for human habitation.

More concerted efforts from the Commonwealth in the 1970s saw a major allocation of funds for Aboriginal housing and the establishment of Aboriginal housing organisations. However the major responsibility for Aboriginal controlled housing was transferred to the states, against the wishes of the Aboriginal housing organisations; the Aboriginal men and women involved in housing identified a need for a self-managed Aboriginal housing organisation, given continuing frustration with the quality of housing and treatment of Aboriginal tenants in private and social housing. By the late 1970s, the movement for an Aboriginal controlled housing organisation in Victoria had gained momentum, at a time when Aboriginal community leaders across Australia set up their own organisations to address inadequate provision of services such as housing, childcare, community services and legal services. At the heart of this movement was the importance of gaining back control – Aboriginal owned and administered housing, not just the provision of accommodation.

"All houses transferred to the Housing Commission from the Ministry of Aboriginal Affairs should be handed over to the Aboriginal Co-operatives for the purpose of housing Aboriginal people." – Nessie Skuta, National Aboriginal Conference representative for country Victoria, 1978. It is clear that transfer of housing to Aboriginal organisations was seen by Victoria's Aboriginal community leaders as being about handing back the control, removed, about righting a previous wrong. By 1981, the Aboriginal Housing Board of Victoria was established to oversee the management of properties owned by the Victorian Government for the provision of housing to Victorian Aboriginal people. Originating as a small community organisation representing Victorian Aboriginal communities, a partnership was formed with the Victorian Government as members advocated for the allocation of accessible and appropriate housing for Aboriginal Victorians and for the better treatment of Aboriginal tenants; the establishment of the AHBV was the culmination of more than two decades of efforts from Victorian Aboriginal community leaders and a major achievement in taking back control and self-management of Aboriginal lives in Victoria.

The founding members of the board had a vision that it would one day own the properties it managed, this has been a driving force for the organisation. Today, Aboriginal Housing Victoria continues to provide culturally sensitive, Aboriginal service delivery as it works towards the goal of self-determination through Aboriginal owned title. In 2016, the Victorian Government announced it would transfer 1,522 property titles worth $500 million to AHV over a two-year period. September 2017 – In a significant step toward self-determination, the Victorian Government announces transfer of ownership of over 500 metropolitan houses to AHV, with non-metropolitan houses to be transferred in two tranches over the following two years; this realises AHV's long held aspiration to own the rental properties it manages on behalf of Government and lays the foundation for future growth.

Voices is a musical composition by the German composer Hans Werner Henze. Written between January and June 1973, it is a collection of 22 independent songs which may be performed individually, with alterations to the instrumentation. In its full version, it is written for mezzo-soprano, tenor and fifteen instrumentalists who are required to play about 70 different instruments from all over the world; the piece lasts 90 minutes. The polystylistic conception of "Voices" results from the different message of the poems. Ref></blocknote> The songs set a diverse range of words all of which are from the twentieth century, the linking theme being alienation and oppression. Henze has said: The voices of the title are those of young and old artists whose work is politically committed; these people are concerned with their fellow human beings, with the contemporary human condition within the world around them and with all the problems of race and class in which they themselves seem fated to be embroiled.: „'Stimmen' für Hans Werner Henze.

Michael David Mizrachi is an American professional poker player who won the 2010, 2012 and 2018 World Series of Poker $50,000 Players Championship. Mizrachi has two World Poker Tour titles, he finished 5th in the Main Event of the 2010 World Series of Poker. In January 2013, Mizrachi signed on as a team pro with Lock Poker. Mizrachi was born in Florida, he is the younger brother of Robert Mizrachi who has numerous World Series of Poker and World Poker Tour finishes to his own name. He has a twin brother Eric Mizrachi and a younger brother, Daniel Jay Mizrachi, a professional DJ known as DJ Mizrachi. Mizrachi is fluent in Hebrew. Growing up, Mizrachi dropped out of college to play poker full-time. Mizrachi has three children: Paul William, Julie Malka, Joseph Mizrachi, he lives in Florida. He purchased a motor home out of his poker winnings which he used to keep his family near him when he was on the road, but sold it as it was depreciating in value. In early 2010, a federal tax lien in the amount of $339,711 was filed against Mizrachi for unpaid taxes related to his earnings from 2005 to 2007.

Mizrachi had two residential properties in Florida foreclosed on including a condominium he owned with his brother, Robert. In 2016, Aidiliy Mizrachi, his wife, divorced Michael for irreconcilable differences. In 2006, Mizrachi won CardPlayer Magazine's Player of the Year Award; as of January 2020, Mizrachi's live tournament winnings exceed $17,000,000. His 64 cashes at the WSOP account for $9,169,857 of those winnings. In the 2005 World Series of Poker, Mizrachi tied the record of seven money finishes in a single year. In the 2008 World Series of Poker, he finished third in the $10,000 Pot-Limit Omaha World Championship.

Despite his strong performance at the 2010 WSOP, Frank Kassela was awarded the Player of the Year award based on the pre-existing scoring system.

This was controversial because some felt that Mizrachi's year was better, which resulted in a refinement of the scoring system. Mizrachi's success in 2010 led to ESPN poker announcer Norman Chad labelling it "The Year of The Grinder". In 2011, Mizrachi just missed winning another WSOP title when he took 2nd in the $2,500 Omaha/Stud Eight or Better event for $158,148.
