What is PTC ?
Phase Transfer Catalyst
phase change, or PTC, some sort of that the transfer of reagent from one phase into another phase where reaction takes place, etc. makes it easy. phase change template special extremely heterogeneous. Reagents, Ionic, usually in an aqueous solution of soluble have, but in the absence of phase change in a phase of organic insoluble. This such as a detergent for the solubility of salts, to the organic phase act.

enjoying phase shift, etc. reactions are faster, etc. products, accessories less and transformations we have the higher also the need for solvents, expensive, or dangerous, that's all in a phase solve the other does not come. Use phase change in green chemistry much is used, because instead of using organic solvents from the water we use.

contrary to many, many more! phase change, the only special reaction water, or the water getaway, but in most reactions, liquid/gas and solid/liquid can also be used....
What is DODAG ?
Destination Oriented Directed Acyclic Graph
Graph of non-circular that briefly DODAG be reincarnated, a graph is just a root. In other words, all the directions just to a node, i.e. the root of the graph leading up. From the graph DODAG in the algorithm, routing RPL in the network such as the Internet of things is used.

The Roots on the graph (DAG) to the node are applied, that no mane, the output is not....

What is LIQ ?
In the knowledge of chemistry and ... solution or a blast, or to Persian, Tajik remedy (Solution) to the homogeneous composition of two or more substance is said to be. In solving () a substance in another substance, one of the materials soluble or (Solute), and another solvent or (Solvent) can be read. For example, candy (solute) when you eat in the saliva (solvent) solution. Or it is possible that the liquid in the other liquid dissolved or gaseous gas other combination. All soluble on the basis of interactions (interaction) between the molecules and ions of solvent and solute are classified and the result of the free energy of the molecule, the material can be. Of course, the solution of the same mixture of uniform or homogeneous....
What is AU ?
Gold or gold with chemical Au the name of a element. The gold metal is soft and dense, and malleable bright yellow and shiny, which is in the vicinity of the air and the water, does not rust and dark not to be. Chemically, gold metal mediator that is in the Group 11 of the periodic table, rather than one of reaction the most elements solid at standard conditions. So can this metal in pure form in nature, in the form of beads, or a piece in the midst of rocks, minerals, crystal and materials, the settling of the alluvial finds. Also among the minerals for combination with other elements, especially been seen, but not abundant. The symbol of this chemical element is Au from the Latin name it aurum, meaning "glow of Dawn" is taken....
What is IERS ?
International Earth Rotation and Reference Systems Service
International service of rotation of the Earth and systems of reference, which refer to the IERS and for the official international service of rotation of the Earth is called the ... responsible for determining the standards of the time and frame of reference, especially through groups, parameters of the orientation of the Earth (EOP) and the system international reference precipitation (ICRS).

What is IfSAR ?
Interferometric Synthetic Aperture Radar
Interference of survey, radar, span a combination that interferes the feasibility of the radar aperture, synthetic and abbreviated InSAR or IfSAR, also called, a method of radar in the sciences of Geodesy and remote sensing is the use of interference spectroscopy, the phase of the waves sent and received to the levels, it is possible to create a model, the next level provides....
What is ASTER ?
Advanced Spaceborne Thermal Emission and Reflection Radiometer
advanced reflection and the oncoming heat that briefly, Esther (ASTER) is called the ... sensor, and one of the five tools of remote sensing, mounted on the satellite Terra, which is in the year 1999 by NASA in the orbit of the Earth was. This sensored from February 2000 to collect data on the surface of the Earth is busy.
