Metallurgical Assay
A metallurgical assay is a compositional analysis of an ore, metal, or alloy, usually performed in order to test for purity or quality. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals (bullion) are assayed by an assay office. Silver is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES). Precious metal items of art or jewelry are frequently hallmarked (depending upon the requirements of the laws of either the place of manufacture or the place of import). Where required to be hallmarked, semi-finished precious metal items of art or jewelry pass through the official testing channels where they are analyzed or assayed for precious metal content. While different nations permit a variety of legally acceptable finenesses, the assayer is actually testing to determine that the fineness of the product conforms with the statement or claim of fin ...

South Dakota School Of Mines And Technology Alumni
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Sherman Antitrust Act Of 1890
The Sherman Antitrust Act of 1890 (, ) is a United States antitrust law which prescribes the rule of free competition among those engaged in commerce. It was passed by Congress and is named for Senator John Sherman, its principal author. The Sherman Act broadly prohibits 1) anticompetitive agreements and 2) unilateral conduct that monopolizes or attempts to monopolize the relevant market. The Act authorizes the Department of Justice to bring suits to enjoin (i.e. prohibit) conduct violating the Act, and additionally authorizes private parties injured by conduct violating the Act to bring suits for treble damages (i.e. three times as much money in damages as the violation cost them). Over time, the federal courts have developed a body of law under the Sherman Act making certain types of anticompetitive conduct per se illegal, and subjecting other types of conduct to case-by-case analysis regarding whether the conduct unreasonably restrains trade. The law attempts to prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-competitive Practices
Anti-competitive practices are business or government practices that prevent or reduce competition in a market. Antitrust laws differ among state and federal laws to ensure businesses do not engage in competitive practices that harm other, usually smaller, businesses or consumers. These laws are formed to promote healthy competition within a free market by limiting the abuse of monopoly power. Competition allows companies to compete in order for products and services to improve; promote innovation; and provide more choices for consumers. In order to obtain greater profits, some large enterprises take advantage of market power to hinder survival of new entrants. Anti-competitive behavior can undermine the efficiency and fairness of the market, leaving consumers with little choice to obtain a reasonable quality of service. Anti-competitive behaviour is used by business and governments to lessen competition within the markets so that monopolies and dominant firms can generate superno ...

List Of People Granted Executive Clemency By Donald Trump
During his tenure as president of the United States (January 20, 2017 – January 20, 2021), Donald Trump granted executive clemency to 237 individuals charged or convicted of federal criminal offenses, using his clemency power under Article II, Section 2 of the Constitution. Ordinarily, all requests for executive clemency for federal offenses are directed to the Office of the Pardon Attorney (OPA) in the U.S. Department of Justice for review; however, Trump frequently bypassed the OPA, and the majority of his executive clemency grants were made to well-connected convicts who did not file a petition with the OPA or meet the OPA's requirements. Overall, Trump granted less clemency than any modern president. Of the pardons and commutations that Trump did grant, the vast majority were to persons to whom Trump had a personal or political connection, or persons for whom executive clemency served a political goal.Kenneth P.

Pardon Of Zay Jeffries
A pardon is a government decision to allow a person to be relieved of some or all of the legal consequences resulting from a criminal conviction. A pardon may be granted before or after conviction for the crime, depending on the laws of the jurisdiction. Pardons can be granted in many countries when individuals are deemed to have demonstrated that they have "paid their debt to society", or are otherwise considered to be deserving of them. In some jurisdictions of some nations, accepting a pardon may ''implicitly'' constitute an admission of guilt; the offer is refused in some cases. Cases of wrongful conviction are in recent times more often dealt with by appeal rather than by pardon; however, a pardon is sometimes offered when innocence is undisputed in order to avoid the costs that are associated with a retrial. Clemency plays a critical role when capital punishment exists in a jurisdiction. Pardons are sometimes seen as a mechanism for combating corruption, allowing a parti ...
