A method in which a large number of assays (from thousands to millions) are performed and assessed in a relatively short time period. Typically, these assays are carried out in microplates of at least 96 wells using automated or robotic technologies. Note the rate of at least 100,000 assays per day has been termed Ultra HTS (UHTS). 

For practitioners of in situ technologies, note that U.S. EPA has issued a policy statement that reinjection of contaminated groundwater is allowed under Resource Conservation and Recovery Act (RCRA)35 36 as long as certain conditions are met. This policy is intended to apply to remedies involving in situ bioremediation and other forms of in situ treatment. Under this policy, groundwater may be reinjected if it is treated aboveground prior to reinjection. Treatment may be by a pump-and-treat system or by the addition of amendments meant to facilitate subsurface treatment. Also, the treatment must be intended to substantially reduce hazardous constituents in the groundwater (either before or after reinjection) the cleanup must be protective of human health and the environment and the injection must be part of a response action intended to clean up the environment.37...

Performance of the unit has proven to be dependent on the level of decontamination required and on the type of coating covering the decontamination. An evaluation of the technology noted that the reliability of the equipment was low and that the system had a low production rate. Wastes recovered by this process may require additional treatment or disposal as radioactive, mixed, or hazardous wastes.

Dan Shoham from Massachusetts Institute of Technology notes that the sequences 15, 172, and 666 (and any other finite sequence) are also contained (in order) within almost all numbers, for similar reasons. John Torrey from North Carolina notes that the probability of a number having exactly one 3 is virtually zero for large enough numbers. 

Expressions (4.3)-(4.5) in which dependences for performance criteria of a chemical process on its rate characteristics are given, emphasize the important idea pronoimced by N.M. Emanuel [1] that chemical kinetics is the scientific basis of chemical technology. Note that expressions for efficiency parameters of chemical reactions frequently do not permit per se to offer specific ways to achieve the maximum output from a chemical process. Realization of this problem is one of main objectives of the value approach, the underlying principles of which are expounded in the next chapters. 

Hydroxyphenylazobenzoic acid (HABA) is another general-purpose matrix. Researchers at the Massachusetts Institute for Technology noted that the ion yield decreases rather slowly as the number of laser shots increases (the decrease in ion yield is faster for other matrices). HABA has a low threshold (for instance, it requires at least 20% less energy than 2,5-DHB). This property turned out to be very important when a poly(siloxane) was fractionated by SEC and high mass fractions with...

Three main water electrolyzer technologies can be distinguished alkaline technology, proton exchange membrane (PEM) technology and solid oxide (SO) technology. Note that these three technologies present numerous similarities respectively with the fuel cells (AFC, PEMFC and SOFC) discussed in...

As mentioned in Sect. I, even the simplest electrosorption systems are extremely complicated. This complexity means that a comprehensive theoretical description that enables predictions for phenomena on macroscopic scales of time and space is still generally impossible with present-day methods and technology. (Note that MD simulations, such as those presented in Sect. II, are only possible up to times of a few himdred nanoseconds.) Therefore, it is necessary to use a variety of analytical and computational methods and to study various simplified models of the solid-hquid interface. One such class of simpHfied models are LG models, in which chemisorbed particles (solutes or solvents) can only be located at specific adsorption sites, commensurate with the substrate s crystal structure. This can often be a very good approximation, for instance, for halides on the (100) surface of Ag, for which it can be shown that the adsorbates spend the vast majority of their time near the fourfold hollow surface sites. A LG approximation to such a continuum model, appropriate for chemisorption of small molecules or ions, ° is defined by the discrete, effective grand-canonical Hamiltonian,...
