Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 ( PO 4) 6 (OH,F,Cl) 2, and the crystal unit cell formulae of the individual ...
About one gram of both TLW and TSW were used in the pyrolysis tests. During these analysis tests, CO 2 and N 2 were used as atmospheres inside of a tubular reactor that was built using quartz tubing. For both CO 2 and N 2 atmospheres the flow rate was 100 mL min −1. [81] External heating was created via a tubular furnace.
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another. ( Cohesion refers to the tendency of similar or identical particles and surfaces to cling to one another.) The forces that cause adhesion and cohesion can be divided into several types.
AP Chemistry is a course geared toward students with interests in chemical biologies, as well as any of the biological sciences. The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year.

The utilized amounts of the various inputs determine the quantity of output according to the relationship called the production function. There are four basic resources or factors of production: land, labour, capital and entrepreneur (or enterprise). [ 1] The factors are also frequently labeled " producer goods or services " to distinguish them ...
The price elasticity of supply ( PES or Es) is a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price. Price elasticity of supply, in application, is the percentage change of the quantity supplied resulting from a 1% change in price.
Production–possibility frontier. In microeconomics, a production–possibility frontier ( PPF ), production possibility curve ( PPC ), or production possibility boundary ( PPB) is a graphical representation showing all the possible options of output for two goods that can be produced using all factors of production, where the given resources ...
