Gold Usage

Gold dissolves in mercury, forming amalgam alloys, but does not react with it. Gold is insoluble in nitric acid, which will dissolve silver and base metals, and this is the basis of the gold refining technique known as inquartation and parting. Nitric acid used to confirm the presence of gold in items, and this is the origin of the colloquial term acid test, referring to a gold standard test for genuine value.

Gambling Disorders Studies

The beliefs of a society about a health condition can have a huge impact on the people who suffer from the disorder. Public opinion can influence public health policy, public and private harm minimization efforts, research funds and treatment support. At the individual level, negative public views of a disease and the stigma it creates can strongly discourage individuals from admitting that he or she has the problem and seeking treatment for the condition. There is little data available on public opinion of gambling disorders; however, a new study published in the Journal of Gambling Studies fills this void with a systematic examination of public opinion on gambling disorders.

Researchers conducted telephone surveys with 8,467 adults in the Toronto area and questioned people about their opinions of how to best understand gambling disorders. Researchers asked if gambling disorders should be treated as a disease or illness, a wrongdoing, a habit, not disease or an addiction similar to drug addiction. Researchers also inquired if people with gambling disorders can get well on their own or must seek treatment to improve and polled adults on whether people with gambling disorders can reduce their gambling to that of a social gambler or if they need to quit altogether. The survey also gathered information on the gambling behavior and demographics of the respondents.

The researchers found that most people viewed gambling disorders as an addiction similar to drug addiction, with one-third seeing gambling as a habit and 17 percent viewing gambling as a form of wrongdoing. Responses to whether gamblers needed treatment to recover showed a split jury, and three out of four thought that abstinence from gambling activities must happen for recovery. Examining the demographics, the researchers found that being female, married, younger and without gambling problems paralleled believing that treatment and abstinence were necessary. In addition, people who viewed gambling problems as a disease or addiction also believed that treatment and abstinence for recovery are necessary.

The researchers noted that public perceptions reported in their study mimic the results of a 2003 study that examined the views of the public on alcohol use, with 71 percent of respondents saying that abstinence must occur for recovery. This popularly held belief is also the view of much of the scientific community as reflected by the upcoming changes the American Psychiatric Association is making.

Finally, researchers concluded that people with gambling disorders were less likely to think that treatment and abstinence were necessary for recovery. This may be because many people who meet the clinical guidelines for a gambling disorder do not think they have a problem and even those who believe they do have a problem are unlikely to seek treatment.

Online casinos, also known as virtual casinos or Internet casinos are online versions of traditional brick and mortar casinos. Online casinos enable gamblers to play and wager on casino games through the Internet.

Online casinos generally offer odds and payback percentages that are comparable to land-based casinos. Some online casinos claim higher payback percentages for slot machine games, and some publish payout percentage audits on their websites. Assuming that the online casino is using an appropriately programmed random number generator, table games like blackjack have an established house edge. The payout percentage for these games is established by the rules of the game.

Online casinos can be divided into two groups based on their interface: web-based and download-only casinos. Some casinos offer both interfaces.

Some casinos offer 'Live gaming', either exclusively, or as part of a wider online casino offering. In live online casinos, popular casino games such as roulette and blackjack are dealt by real dealers in casino studios, in an attempt to convey more of the atmosphere of a physical casino. Player actions including chat such as 'hit' in the game of blackjack may be transmitted to the dealer; in some online casinos more than one player may 'sit' at a particular 'seat' on the table, and in this case there is no interactivity between player and dealer. The question of which player s requested the extra card that the dealer dealt and which chose to 'stand' will be handled by the software. It is usual for players to be able to observe a video feed of the action, and equally common for players to opt to turn it off, if they lack the bandwidth - as the cards are read by OCR and other technology, the video feed is only ever a visual cue.

Web-based online casinos

Web-based online casinos are websites where users may play casino games without downloading software to the local computer. Games are mainly represented in the browser plug-ins Macromedia Flash, Macromedia Shockwave, or Java and require browser support for these plug-in. In addition, bandwidth is needed since all graphics, sounds and animations are loaded through the web via the plug-in. Some online casinos also allow game play through a plain HTML interface. Apple devices such as IPod, IPad and IPhone cannot play Flash games as the technology is not supported.

Download-based online casinos

Download-based online casinos require the download of the software client in order to play and wager on the casino games offered. The online casino software connects to the casino service provider and handles contact without browser support. Download-based online casinos generally run faster than web-based online casinos since the graphics and sound programs are located within the software client, rather than having to be loaded from the Internet. On the other hand, the initial download and installation of a download-based online casino client does take time. As with any download from the Internet, the risk of the program containing malware does exist. Still the graphics and sounds at download-based online casinos are most of the time much better than those at web-based online casinos.

Bastra

Bastra, the Greek deformation of the Arabic word Basra, which is also a similar game played in Egypt, Lebanon and other Middle-Eastern countries, is a popular fishing card game similar to Cassino very popular in Cyprus.

The game was probably introduced to the Cypriots through the Turks during the Ottoman occupation. There are also variations of the game played in Greece, such as Diloti and Kseri. The game has been exported by both the Cypriot and Turkish diasporas and is played in Cypriot communities in Australia, Canada, England and the United States, usually passed on by the first generation of immigrants to their children and grandchildren. Despite this, the game is virtually unknown in these countries outside of the Cypriot and Greek communities. In Turkey the game is still very popular.

The game is played with a 52 card deck and can involve two, three or four players, although the game is most interesting in the two or four player versions. In the four player version, the players can play for themselves or in two player teams. The first team or player to score 100 points is the winner.
The play

The dealer starts by dealing 1 card to each player, starting with the player on the dealer's left, until each player has 4 cards. The dealer then places 4 cards in the middle of the table, called the board. If 1 or more of the 4 cards is a jack, the dealer returns the jacks to the bottom of the deck and replaces it or them with the next cards from the top of the deck. The play begins with the player to the dealer’s left until all cards are played out. The players either collect fish cards from the board or add a card to the board if they cannot fish any cards. After the cards are exhausted, the dealer then deals each player 4 more cards from the remaining deck. The dealer, however, does not deal 4 cards onto the board as done for the opening hand. The hands are played out until there are no remaining cards to be dealt.

In the two player version, each round has six hands, in the three player version, each round has four hands, and in the four player version, each round consists of three hands.
Scoring

The scoring is as follows:

    The aces, which have a numeral value of 1, are worth 1 point each.
    The jacks are worth 1 point each.
    The two of clubs is worth 2 points.
    The ten of diamonds is worth 3 points.
    The player or team that collects the most cards in a given hand receives 3 points. In the event of a tie, each player or team receives 3 points.
    The player or team that collects all the cards in play without benefit of a jack receives 10 points, or a bastra.

Collecting cards

The object of the game is to collect total cards and cards that are worth various points. Cards are collected as follows:

    Pairing: Any card may be used to take another card or cards of the same denomination, i.e. a 7 takes a 7, a king takes a king, a 6 takes two 6s, etc.
    Combining: Multiple cards may be collected through adding the numeral value of the cards together. For example, the board shows 2, an ace, 5 and 4. A player with a 3 could take 2 and the ace 2+1=3, or a player holding a 9 could take 5 and 4 5+4=9, or a player holding a 7 could take 2, the ace and 4 2+1+4=7.
        A player may also collect combinations of the same sum. For example, if the board shows 5, 4, 2 and 7, a 9 would take all 4 cards, i.e. 5+4 and 2+7=9.
    Pairing and combining: Taking cards through pairing and combining can occur on the same play. For example, if the board showed 3 6 5 4 and 9, a 9 would take all the cards, i.e. 3+6 and 5+4=9, plus the 9 would be paired with the 9.

On the last hand, there are often uncollected cards left on the board. These cards are awarded to the last player or team to collect a card.
Jack

The jack is the most powerful card because it can collect all the cards on the board. However, if a jack is played onto an empty board, it is lost and remains in play until one of the players can collect it, usually with another jack.

The bastra is the most important scoring play of the game since it is worth 10 points. A bastra occurs when a player succeeds in clearing the board without benefit of a jack. For example, if the board shows just a 7 and a player collects it with another 7, that player or team receives 10 points. In another scenario, if the board shows 3 and 2 and a player collects them with a 5, that player or team also receives 10 points. In the rare event that a jack takes a solitary jack, a 50 point bastra is awarded.

The players place the collected cards close to their position at the table. To record bastras, the player places the bastra card face up, sticking out of the player's pile of collected cards. The dealer should be careful to place his or her collected cards away from the deck, so as to avoid confusion. Players are not allowed to look at their collected cards until the end of the hand. At the end of the hand, the players count their total cards and points.

The game ends when one player or team reaches 100 points. In the rare event of a tie 2 players or teams finish even beyond the 100 point mark there are various tie-breaking options, determined by the players by mutual consent. The game can be declared a draw, or an extra hand or hands can be played until the tie is broken. Or the players can extend the game to a fixed number of points 20, 30 or 50.
