Source mixing

Application of integrated stable hydrogen isotope and hydrogeochemical models to the present free waters systems provides important information on their sources, mixing phenomena and underground dynamics that can be profitably used in problems of groundwater resources management, as well as in environmental protection.

Aquatic humic substances may be found in groundwater, river water, lakes, marshes, bogs, swamps, and seawater. The source of the humates may be autochthonous or allochthonous that is, the humates may be formed from phytoplankton in the water or they may be leached into the aquatic environment from terrestrial plants, leaf litter, soil, or subsurface deposits. Relatively undisturbed marine environments have humic and fulvic acids formed almost entirely from native phytoplankton inland surface waters contain major contributions from allochthonous sources. Mixing of the two types of materials may occur, as in the estuaries of rivers. 

In systems G and H, sodium sulfate was used as a sodium source mixed with kaolinite and calcium acetate. Sodium sulfate melts at approximately 884 C. Therefore, at 750 C no interaction between kaolinite and sodium sulfate was seen (systems G and H). In system G nepheline was formed at 1000 C, with none of the sulfur released from the sodium sulfate involved in the formation of any new high temperature minerals. However, in system H additional feldspathoids (i.e., gehlenite and hauyne) other than nepheline were formed. In this case, sulfur was involved in forming new high temperature minerals.

The spectra discussed above indicate the presence of the ene-dithiolate electronic buffering effect, but not its cause. Insight into this cause can be gained by comparing spectra of a compound that have been collected with different photon energies to evaluate the photoionization cross sections. From previous experimental studies and calculations of atomic photoionization cross sections,it is expected that ionizations from orbitals with significant Mo 4d contributions will increase in intensity compared to ionizations of primarily S 3p character when data collected with a Hell photon source are compared to data collected with a Hel photon source. Mixing... 

Ignition Ignition occurs when a sufficient concentration and proper form of the fuel source mixes with an oxidizing agent at the proper temperature. 

Computer-based systems are becoming common that input a variety of sources, mix, process, and store, aU within the computer environment, eliminating much of the equipment found in conventional studios.

An efficient diastereo- and enantio-selective reductive coupling of alkenylazaarenes with ketones has been developed, which provides aromatic heterocycles bearing tertiary-alcohol-containing side chains, with copper(II) acetate and Taniaphos SL-TOOl-1 as the catalytic system and phenylsilane is the hydride source." Mixed phosphorus-sulfiir ligands derived from carbohydrates are good catalyst precursors...
