A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence Pete Maravich Jersey , phosphorescence, and other forms of luminescence, in which a material emits light.

For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light Paul Millsap Jersey , while some eventually blacken.

You don’t just find pigments for paint, but also for coloring ink, plastic, fabric, cosmetics, food Mike Muscala Jersey , and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. This powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.

Pigments appear the colors they are because they selectively reflect and absorb certain wavelengths of visible light. White light is a roughly equal mixture of the entire spectrum of visible light with a wavelength in a range from about 375 or 400 nanometers to about 760 or 780 nm. When this light encounters a pigment, parts of the spectrum are absorbed by the molecules or ions of the pigment. In organic pigments such as diazo or phthalocyanine compounds the light is absorbed by the conjugated systems of double bonds in the molecule.

The appearance of pigment for coating is intimately connected to the color of the source light. Sunlight has a high color temperature, and a fairly uniform spectrum, and is considered a standard for white light. Artificial light sources tend to have great peaks in some parts of their spectrum Mike Dunleavy Jersey , and deep valleys in others. Viewed under these conditions, pigments will appear different colors.

Naturally occurring pigments such as ochres and iron oxides have been used as colorants since prehistoric times. Archaeologists have uncovered evidence that early humans used paint for aesthetic purposes such as body decoration.

Before the development of synthetic pigments, and the refinement of techniques for extracting mineral pigments, batches of color were often inconsistent. With the development of a modern color industry, manufacturers and professionals have cooperated to create international standards for identifying, producing Mike Bibby Jersey , measuring, and testing colors.

Selection of a pigment for a particular application is determined by cost, and by the physical properties and attributes of the pigment itself. For example, a pigment that is used to color glass must have very high heat stability in order to survive the manufacturing process; but, suspended in the glass vehicle, its resistance to alkali or acidic materials is not an issue. In artistic paint Kirk Hinrich Jersey , heat stability is less important, while lightfastness and toxicity are greater concerns.
Gambling has become one of the largest sources of revenue in the world. There are people all over the world that put money into different types of gambling. While casinos and some other forms of betting are very popular, one of the most popular forms of gambling in recent years has been sports betting.

Countries all over the world have different scenes and laws surrounding gambling and sports betting in general. Morocco is one of the largest scenes for gambling in general in the continent of Africa.

Sports betting is popular because people do not only have the opportunity to put their money on the line, but it helps them to become even more invested in the sports that they are watching. Some people might say that this is a great way to increase the support of fans in sports, but others would say that it is damaging to society.

This is particularly true in Morocco. Morocco is a country that harbors a vast majority of people that are of the Islamic faith. In traditional Islamic practices, to gamble with not be in compliance with their faith. Because of this Kent Bazemore Jersey , it is somewhat of a surprise that the country has allowed gambling to take place within its borders.

There is no doubt that there are many people that are against the fact that gambling takes place within the country, but the fact of the matter is that some of these Muslim countries feel that they need money to continue running. Gambling is a great way to do this. Because of this, there have been many countries in the areas of the globe that are generally Islamic that have implemented sports betting into their system. Among these countries are Egypt, Tunis and Lebanon. Since implementing gambling into the countries there has been revenue going to the country. This shows that there is definitely a market for gambling, even in religious countries.

One of the most popular sports in the country is of course soccer. Soccer is popular all over the world and represents a large part of the sports interest within the country. It is a sport that people follow all over the country and is a great sport for betting because so many people are not only interested in the sport, but they are informed about it. The soccer played in Morocco is between teams within the country and they also play games against teams from other countries.

The country has certainly found a source of revenue in gambling. There are many counties that have legalized betting on sports because it is already taking place within their borders. There are millions and even billions of dollars being passed around illegally. Many countries Josh Smith Jersey , like Morocco, have decided that if people are going to do it regardless of the legality of the actions, that they might as well make it legal and find a way to make revenue off of the actions of their citizens. The gambling scene within the country is as good as any in the North African region and will only continue to.
