Atmospheric chemistry The first scientific studies of atmospheric composition began in the 18th century, as chemists such as Joseph Priestley, Antoine Lavoisier and Henry Cavendish made the first measurements of the composition of the atmosphere. In the late 19th and early 20th centuries interest shifted towards trace ...

Bioavailability Where "AUC" refers to the concentration of the drug in the blood over time "t" = 0 to "t" = ∞, "C" refers to the maximum concentration of the drug in the blood. When "T" is given, it refers to the time it takes for a drug to reach "C". While the mechanisms by which a formulation affects bioavailability ...

Bioavailability Other factors may include, but are not limited to: Each of these factors may vary from patient to patient (inter-individual variation), and indeed in the same patient over time (intra-individual variation). In clinical trials, inter-individual variation is a critical measurement used to assess the bioav...

Bioavailability This failure leaves open the question of whether or not an individual in a group is likely to experience the benefits described by the mean-difference comparisons. Further, even if this issue were discussed, it would be difficult to communicate meaning of these inter-subject variances to consumers and/o...

Miguel Itzigsohn (1908–1978) was an Argentine astronomer and observer of comets, credited by the Minor Planet Center with the discovery of 15 asteroids between 1948 and 1954. The outer main-belt asteroid 1596 Itzigsohn, which he discovered himself, was named in his memory on 1 August 1980 (). Itzigsohn was a professor ...

Shallow donor A shallow donor refers to a donor that contributes an electron that exhibits energy states equivalent to atomic hydrogen with an altered expected mass i.e. the long range coulomb potential of the ion-cores determines the energy levels. Essentially the electron orbits the donor ion within the semiconductor...

Physics of computation The study of the physics of computation relates to understanding the fundamental physical limits of computers. This field has led to the investigation of how thermodynamics limits information processing, the understanding of chaos and dynamical systems, and a rapidly growing effort to invent new ...
