Qatar
Qatar (, ; ar, قطر, Qaṭar ; local vernacular pronunciation: ), officially the State of Qatar,) is a country in Western Asia. It occupies the Qatar Peninsula on the northeastern coast of the Arabian Peninsula in the Middle East; it shares its sole land border with Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. The Gulf of Bahrain, an inlet of the Persian Gulf, separates Qatar from nearby Bahrain. The capital is Doha, home to over 80% of the country's inhabitants, and the land area is mostly made up of flat, low-lying desert. Qatar has been ruled as a hereditary monarchy by the House of Thani since Mohammed bin Thani signed a treaty with the British in 1868 that recognised its separate status. Following Ottoman rule, Qatar became a British protectorate in 1916, and gained independence in 1971. The current emir is Tamim bin Hamad Al Thani, who holds nearly all executive and legislative authority under the Constitution of Qat ...

Qualitative Inorganic Analysis
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds. It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods. The solution is then treated with various reagents to test for reactions characteristic of certain ions, which may cause color change, precipitation and other visible changes. Qualitative inorganic analysis is that branch or method of analytical chemistry which seeks to establish the elemental composition of inorganic compounds through various reagents. Physical appearance of inorganic salts Detecting cations According to their properties, cations are usually classified into six groups. Each group has a common reagent which can be used to separate them from the solution. To obtain meaningful results, the separation must be done in the sequence specified below, as some ...

Qa (Cyrillic)
Qa (Ԛ ԛ; italics: ) is a letter of the Cyrillic script. Its form is based on the Latin letter Q (Q q). Depending on the font, the uppercase form can look like a reversed Cyrillic letter Р. Qa is used in the alphabet of the Kurdish language and in the old alphabet of the Abkhaz language. In both it represents the voiceless uvular plosive .http://unicode.org/L2/L2007/07003-n3194-cyrillic.pdf It was also used in the old alphabet of the Ossetian language. This character appeared in newspapers and articles such as 1955's ''Кӧрдо''. The letter was also used in the scrapped version of the Azerbaijani alphabet, it was however eliminated and replaced by Ҝ in Dagestan.

Qa (cuneiform)
The cuneiform sign qa, is a common-use sign of the Amarna letters, the ''Epic of Gilgamesh,'' and other cuneiform texts (for example Hittite texts). It has a secondary sub-use in the Amarna letters for ka4. Linguistically, it has the alphabetical usage in texts for ''q'', ''a'', or ''qa'', and also a replacement for ''"q"'', by ''k'', or ''g''. ''Epic of Gilgamesh'' usage The ''qa'' sign usage in the ''Epic of Gilgamesh'' is as follows: ''qa''-(109 times). References * Moran, William L. 1987, 1992. ''The Amarna Letters.''

Question Answering
Question answering (QA) is a computer science discipline within the fields of information retrieval and natural language processing (NLP), which is concerned with building systems that automatically answer questions posed by humans in a natural language. Overview A question answering implementation, usually a computer program, may construct its answers by querying a structured database of knowledge or information, usually a knowledge base. More commonly, question answering systems can pull answers from an unstructured collection of natural language documents. Some examples of natural language document collections used for question answering systems include: * a local collection of reference texts * internal organization documents and web pages * compiled newswire reports * a set of Wikipedia pages * a subset of World Wide Web pages Types of question answering Question answering research attempts to deal with a wide range of question types including: fact, list, definition, ''H ...

Quantitative Analysis (chemistry)
In analytical chemistry, quantitative analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample. Methods Once the presence of certain substances in a sample is known, the study of their absolute or relative abundance could help in determining specific properties. Knowing the composition of a sample is very important, and several ways have been developed to make it possible, like gravimetric and volumetric analysis. Gravimetric analysis yields more accurate data about the composition of a sample than volumetric analysis but also takes more time to perform in the laboratory. Volumetric analysis, on the other hand, doesn't take that much time and can produce satisfactory results. Volumetric analysis can be simply a titration based in a neutralization reaction but it can also be a precipitation or a complex forming reaction as well as a titration based in a redox reactio ...

Quality Assurance
Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design, reliability, and maintainability expectations of that customer. The core purpose of Quality Assurance is to prevent mistakes and defects in the development and production of both manufactured products, such as automobiles and shoes, and delivered services, such as automotive repair and athletic shoe design. Assuring quality and therefore avoiding problems and delays when delivering products or services to customers is what ISO 9000 defines as that "part of quality management focused on providing confidence that quality requirements will be fulfilled". This defect prevention aspect of quality assurance differs from the defect detection aspect of quality control and has been referred to as a ''shift left'' since it focuses on quality effor ...
