Colorfulness
Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are not clearly distinguished. The precise meanings of the terms vary by what other functions they are dependent on. * Colorfulness is the "attribute of a visual perception according to which the perceived color of an area appears to be more or less chromatic (Any color that is absent of white, grey, or black)"., page 87. The colorfulness evoked by an object depends not only on its spectral reflectance but also on the strength of the illumination, and increases with the latter unless the brightness is very high (Hunt effect (color), Hunt effect). * Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarl ...

Nine (purity)
Nines are an informal logarithmic notation for proportions very near to one or, equivalently, percentages very near 100%. Put simply, "nines" are the number of consecutive nines in a percentage such as 99% (two nines) or a decimal fraction such as 0.999 (three nines). Their common uses include grading the purity of materialsespecially precious metals and industrial gasesor measuring the availability of a service. Nomenclature The ''nines'' are a count of the leftmost digits 9 that appear in a proportion. For example, 90% would be described as "one nine"; 99% as "two nines"; 99.9% as "three nines"; and so forth. However, there are different conventions for representing inexact multiples of 9. For example, a percentage of 99.5% could be expressed as "two nines five" (2N5, or N2.5) or as 2.3 nines, following from the logarithm definition. A percentage of 100% would, in theory, have an infinite number of nines – though, in the context of purity of materials, 100% is virtually ...

Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of ''fine metal'' therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% gold and 24 karat gold is considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pure Substance
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure. Chemical substances can exist in several different physical states or phases (e.g. solids, liquids, gases, or plasma) without changing their chemical composition. Substances transition between these phases of matter in response to changes in temperature or pressure. Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Purity
In chemistry, chemical purity is the measurement of the amount of impurities found in a sample. Several grades of purity are used by the scientific, pharmaceutical, and industrial communities. Some of the commonly used grades of purity include: * ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the '' Reagent Chemicals'' publication, issued by the ACS. It is suitable for food and laboratory uses. * Reagent grade is almost as stringent as the ACS grade. * USP grade meets the purity levels set by the United States Pharmacopeia The ''United States Pharmacopeia'' (''USP'') is a pharmacopeia (compendium of drug information) for the United States published annually by the over 200-year old United States Pharmacopeial Convention (usually also called the USP), a nonprofi ...

Contaminant
Contamination is the presence of a constituent, impurity, or some other undesirable element that renders something unsuitable, unfit or harmful for the physical body, natural environment, wiktionary:Workplace, workplace, etc. Types of contamination Within the sciences, the word "contamination" can take on a variety of subtle differences in meaning, whether the contaminant is a solid or a liquid, as well as the variance of environment the contaminant is found to be in. A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. The following represent examples of different types of contamination based on these and other variances. Chemical contamination In chemistry, the term "contamination" usually describes a single constituent, but in specialized fields the term can also mean chemical mixtures, even up to the level of cellular materials. All chemicals contain some level of impurity. Contamination may be recognized or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impurity
In chemistry and materials science, impurities are chemical substances inside a confined amount of liquid, gas, or solid. They differ from the chemical composition of the material or compound. Firstly, a pure chemical should appear in at least one Phase (matter), chemical phase and can also be characterized by its phase diagram. Secondly, a pure chemical should prove to be homogeneous (i.e., a uniform substance that has the same composition throughout the material). The perfect pure chemical will pass all attempts to separate and purify it further. Thirdly, and here we focus on the common chemical definition, it should not contain any trace of any other kind of chemical species. In reality, there are no absolutely 100% pure chemical compounds, as there is always some small amount of contamination. The levels of impurities in a material are generally defined in relative terms. standardization, Standards have been established by various organizations that attempt to define the permi ...

Ritual Purity In Islam
Purity () is an essential aspect of Islam. It is the opposite of ''najāsa'', the state of being ritually impure. It is achieved by first removing physical impurities (for example, urine) from the body, and then removing ritual impurity through ''wudu'' (usually) or ''ghusl''. In the Quran The Quran says: and there is one verse which concerned with ''taharah'' or purity, and impurity of humans: Shia views Ayatollah Ali al-Sistani does not believe in the impurity of People of the Book (Jews, Christians, and Zoroastrians). Some scholars such as Mohsen Fayz Kashani (d. 1680) and Sulayman ibn Abdullah Mahuzi (d. 1708) did not believe in the impurity of non-believers, and particularly non-People of the Book. Kashani believes that the impurity of kuffar is spiritual and internal, so there is no need to wash after touching them. This group believes in the purity of non-Muslims and of all humans.

Purity In Buddhism
Purity (Pali: ''Vissudhi'') is an important concept within much of Theravada and Mahayana Buddhism, although the implications of the resultant moral purification may be viewed differently in the varying traditions. The aim is to purify the personality of the Buddhist practitioner so that all moral and character defilements and defects ('' kleśas'' such as anger, ignorance and lust) are wiped away and nirvana can be obtained. Theravada Theravada Buddhism regards the path of self-purification as absolutely vital for reaching Nibbana. The main task of the Theravada Buddhist monk is to eradicate flaws in morality and character through meditation and moral cultivation, in alliance with the cultivation of insight or wisdom ( Paññā), so that the purity of Nibbana can be achieved. So important is this notion of purity in Theravada Buddhism that the famed Buddhist monk and commentator Buddhaghosa composed a central thesis on ''dhamma'' called ''The Path of Purification'' (''Visu ...

Ritual Purification
Ritual purification is a ritual prescribed by a religion through which a person is considered to be freed of ''uncleanliness'', especially prior to the worship of a deity, and ritual purity is a state of ritual cleanliness. Ritual purification may also apply to objects and places. Ritual uncleanliness is not identical with ordinary physical impurity, such as dirt stains; nevertheless, body fluids are generally considered ritually unclean. Most of these rituals existed long before the germ theory of disease, and figure prominently from the earliest known Ancient Near Eastern religion, religious systems of the Ancient Near East. Some writers connect the rituals to taboos. Some have seen benefits of these practices as a point of health and preventing infections especially in areas where humans come in close contact with each other. While these practices came before the idea of the germ theory was public in areas that use daily cleaning, the destruction of infectious agents seems t ...
