Acid Test (gold)
An acid test is any qualitative chemical or metallurgical assay which uses acid; most commonly, and historically, the use of a strong acid to distinguish gold from base metals. Figuratively, acid test is any definitive test for some attribute, e.g. of a person's character, or of the performance of product. Chemistry Testing for gold with acid focuses on the fact that gold is a noble metal which is resistant to change by corrosion, oxidation, or acid. The acid test for gold is to rub the gold-colored item on black stone, which will leave an easily visible mark. The mark is tested by applying nitric acid, which dissolves the mark of any item that is not gold. If the mark remains, it is tested by applying aqua regia (nitric acid and hydrochloric acid). If the mark is removed, then this test dissolves the gold, proving the item to be genuine gold. More accurate testing of the item for its fineness or purity can be done through the use of differing strengths of aqua regia and compara ...

Lithology
The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy. Physical characteristics include colour, texture, grain size, and composition. Lithology may refer to either a detailed description of these characteristics, or a summary of the gross physical character of a rock. Examples of lithologies in the second sense include sandstone, slate, basalt, or limestone. Lithology is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas. In certain applications, such as site investigations, lithology is described using a standard terminology such as in the European geotechnical standard Eurocode 7. Rock type The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed directly from magma, which is a mixture of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is transmitted via analogue radio in AM on medium wave 693 and 909 kHz and digitally via digital radio, television and on the BBC Sounds service. Due to rights restrictions, coverage of some events, particularly live sport, is not available online or is restricted to UK addresses. The station broadcasts from MediaCityUK in Salford in Greater Manchester and is a department of the BBC North division. According to RAJAR, the station broadcasts to a weekly audience of 4.8 million with a listening share of 2.7% as of Sep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quick Ratio
In finance, the quick ratio, also known as the acid-test ratio is a type of liquidity ratio, which measures the ability of a company to use its ''near cash'' or quick assets to extinguish or retire its current liabilities immediately. It is defined as the ratio between quickly available or liquid assets and current liabilities. Quick assets are current assets that can presumably be quickly converted to cash at close to their book values. A normal liquid ratio is considered to be 1:1. A company with a quick ratio of less than 1 cannot currently fully pay back its current liabilities. The quick ratio is similar to the current ratio, but provides a more conservative assessment of the liquidity position of firms as it excludes inventory, which it does not consider as sufficiently liquid. Formula :\text = \frac or specifically: :\text = \frac It can also be expressed as: Ratio :\text = \frac Ratios are tests of viability for business entities but do not give a complete pi ...

Acid1
Acid1, originally called the Box Acid Test, was a test page for web browsers. It was developed in October 1998 and was important in establishing baseline interoperability between early web browsers, especially for the Cascading Style Sheets 1.0 specification. As with acid tests for gold which produce a quick and obvious assessment of the quality of a piece of metal, the web acid tests were designed to produce a clear indication of a browser's compliance to web standards. History Acid1 tests many features on one page against a reference image. Acid1 was developed by Todd Fahrner, who was frustrated with the lack of stringent tests to improve browser interoperability. After looking at tests developed by Braden McDaniel that used reference renderings to clarify the intended result, Fahrner developed a comprehensive test that resulted in a quirky-looking graphic. In 1999, the test was incorporated into the CSS1 test suite. The text used in Acid1 is an allusion to T. S. Eliot's poe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid2
Acid2 is a webpage that test web browsers' functionality in displaying aspects of HTML markup, CSS 2.1 styling, PNG images, and data URIs. The test page was released on 13 April 2005 by the Web Standards Project. The Acid2 test page will be displayed correctly in any application that follows the World Wide Web Consortium and Internet Engineering Task Force specifications for these technologies. These specifications are known as web standards because they describe how technologies used on the web are expected to function. The Acid2 tests rendering flaws in web browsers and other applications that render HTML. Named after the acid test for gold, it was developed in the spirit of Acid1, a relatively narrow test of compliance with the Cascading Style Sheets 1.0 (CSS1) standard. As with Acid1, an application passes the test if the way it displays the test page matches a reference image. Acid2 was designed with Microsoft Internet Explorer particularly in mind. The creato ...

Acid3
The Acid3 test is a web test page from the Web Standards Project that checks a web browser's compliance with elements of various web standards, particularly the Document Object Model (DOM) and JavaScript. If the test is successful, the results of the Acid3 test will display a gradually increasing fraction counter below a series of colored rectangles. The number of subtests passed will indicate the percentage that will be displayed on the screen. This percentage does not represent an actual percentage of conformance as the test does not really keep track of the subtests that were actually started (100 is assumed). Moreover, the browser also has to render the page exactly as the reference page is rendered in the same browser. Like the text of the Acid2 test, the text of the Acid3 reference rendering is not a bitmap, in order to allow for certain differences in font rendering. Acid3 was in development from April 2007, and released on 3 March 2008. The main developer was Ian Hicks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ACID
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM In ...
