The gold concentration in ores was determined by fire assay and AAS for samples UG1 to UG4 and by fire assay and gravimetry for samples UG5 and UG6. The silver concentration was obtained by chemical digestion and ICP-OES. Ore samples were extracted from underground locations and donated by a Colombian mining company.

It follows from this equation that the concentration probability is distributed according to the normal law in regions without infermittency. The equation enables one to calculate the intensity of concentration fluctuations at the edge of a turbulent flow for a completely turbulent fluid.

Percolation Theory - mit.edu
Let each site in a lattice be occupied at random with probability p, that is, each site is occupied (with probability p) or empty (with probability 1 p) independent of the status (empty or occupied) of any of the other sites in the lattice. We call pthe occupation probability or the concentration.

Chapter 5 Diffusion - University of Tennessee
For the vacancy diffusion mechanism the probability for any atom in a solid to move is the product of the probability of finding a vacancy in an adjacent lattice site (see Chapter 4): and the probability of thermal fluctuation needed to overcome the energy barrier for vacancy motion Diffusion – Thermally Activated Process (III)

2.7 Doped Semiconductors - University of Colorado Boulder
Statistical thermodynamics can be used to obtain the probability that the impurity is ionized. The resulting expression is similar to the Fermi-Dirac probability function except for a factor which accounts for the fact that the impurity can only give off one hole or one electron and also accounts for the degeneracy of the valence band.

Concentration parameter - Wikipedia
In probability theory and statistics, a concentration parameter is a special kind of numerical parameter of a parametric family of probability distributions. Concentration parameters occur in two kinds of distribution: In the Von Mises–Fisher distribution, and in conjunction with distributions whose domain is a probability distribution, such ...

6 EQUATIONS OF RADIOACTIVE DECAY AND GROWTH
6.1 LAW OF RADIOACTIVE DECAY The fundamental law of radioactive decay is based on the fact that the decay, i.e. the transition of a parent nucleus to a daughter nucleus is a purely statistical process. The disintegration (decay) probability is a fundamental property of an atomic nucleus and remains equal in time.

What is the geological process that produces gold veins ...
The concentration of Au (Gold) will be highest in the center of the vein and will gradually decrease towards the rim of the vein. The mineralized host rock also contains gold in disseminated form. The zone of highest concentration is called Proximal zone, that with moderate concentration is called Intermediate zone and where gold concentration ...

Earth's continental crustal gold endowment - ScienceDirect
The factors that control the concentration of gold at certain sites in the Earth's crust to deposit level as well as the ultimate source of the gold in the various deposits remain, however, topics of debate (e.g. Bierlein et al., 2006, Groves et al., 2005). Even on a scale beyond that of ore deposits, gold is distributed unevenly in Earth.

NanoHybrids - Optical density, absorbance & extinction of ...
In the case of homogenous colloidal solutions (such as Gold Nanoparticles), the optical density is a function of the solution’s concentration. Therefore, optical density can also be expressed as: [the molar absorbance coefficient (the absorbance of the solution per unit length per mole of solute) x the molar concentration of the solution x ...

2.7 Doped Semiconductors - University of Colorado Boulder
Doped semiconductors are semiconductors which contain impurities, foreign atoms which are incorporated into the crystal structure of the semiconductor. These impurities can either be unintentional due to lack of control during the growth of the semiconductor or they can be added on purpose to provide free carriers in the semiconductor.
