Biodegradation testing of chemicals with high Henry's constants - Separating mass and effective concentration reveals higher rate constants.
During simulation-type biodegradation tests, volatile chemicals will continuously partition between water phase and headspace. This study addressed how (1) this partitioning affects test results and (2) can be accounted for by combining equilibrium partition and dynamic biodegradation models. An aqueous mixture of 9 (semi)volatile chemicals was first generated using passive dosing and then dilu...
متن کاملEstimating rate constants in
The EM algorithm, e.g. as Baum-Welch reestimation, is an important tool for parameter estimation in discrete-time Hidden Markov Models. We present a direct reestimation of rate constants for applications in which the underlying Markov process is continuous in time. Previous estimation of discrete-time transition probabilities is not necessary.
متن کاملMass Hierarchies with Anisotropies and Running Constants
The gravitational equations of the three dimensional (3D) brane world are investigated for both off–diagonal and warped 5D metrics which can be diagonalized with respect to some anholonomic frames when the gravitational and matter fields dynamics are described by mixed sets of holonomic and anholonomic variables. We construct two new classes of exact solutions of Kaluza–Klein gravity which gene...
متن کاملMinkowski-Siegel Mass Constants
Let X denote either a vector space over the real numbers R or a module over the integers Z . A symmetric positive definite bilinear form f on X is an inner product if, for any linear form g on X, there exists a unique x ∈ X such that g(y) = f(x, y) for all y ∈ X. This nondegeneracy condition is superfluous whenX is a finite-dimensional vector space [1, 2]. The pair (X, f) is called an inner pro...
متن کاملDyes with High Dielectric Constants
Materials with high dielectric constants find wide application in electronic devices, for instance in capacitors, wave guides, and reflective materials for electromagnetic radiation. For very high dielectric constants materials with ion or dipole lattices are usually used, for example the dielectrics in tantalum capacitors. However, these materials have the disadvantage of a rather strong coupl...
