The transport of chemicals in semen

Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2005
AbstractThree mechanisms have been proposed for exposure of the conceptus to chemicals in semen: access of chemicals to the maternal circulation after absorption from the vagina, direct chemical exposure of the conceptus following transport from the vagina to the uterine cavity, and delivery to the egg and subsequent conceptus of chemical bound to the ...

Chemical fluid transport (CFT)

Geochemistry, 2013
Abstract Gas phase transport according to chemical fluid transport (CFT) in Earth's crust as well as in the solar nebula is characterized by very high transport efficiency. Systematic investigations of mobilization, transport and deposition of gaseous MeX (Me = metal, X = F or Cl) compounds by solid gas equilibrium reactions are suitable to explain ...

Chemical enhancers for transdermal drug transport

European Journal of Drug Metabolism and Pharmacokinetics, 2001
In its first part, this review paper discusses skin morphology and barrier function of the stratum corneum for drug permeation after its transdermal administration or topical application. Further, the paper presents the main methods for overcoming the skin permeation barrier, which plays an important role for transdermal drug administration.

Charge Transport in Chemically Doped 2D Graphene

Physical Review Letters, 2008
We report on a numerical study of electronic transport in chemically doped 2D graphene materials. By using ab initio calculations, a self-consistent scattering potential is derived for boron and nitrogen substitutions, and a fully quantum-mechanical Kubo-Greenwood approach is used to evaluate the resulting charge mobilities and conductivities of ...

Chemical Transport Modelling

2011
A model in the here discussed form is first of all a description of complex processes in nature. This starts with a description by words or graphics (conceptual model) and goes up to complex mathematical or numerical simulation models that run on supercomputers. The complexity of a model is determined by several factors.

Chemical Vapor Transport Reactions

2012
This comprehensive handbook covers the diverse aspects of chemical vapor transport reactions from basic research to important practical applications. The book begins with an overview of models for chemical vapor transport reactions and then proceeds to treat the specific chemical transport reactions for the elements, halides, oxides, sulfides ...

CHEMICAL Transportation & Distribution

Chemical & Engineering News Archive, 1993
The U.S. chemical industry contends that it has a fairly good track record for safe distribution and transport of its products. But it also recognizes that it is not perfect. One major accident, albeit rare, can be of such devastating and press-worthy proportions, that the entire industry is tarnished. "We have to find a way to prevent accidents of any

Transport-driven chemical oscillations: a review

Physical Chemistry Chemical Physics
We review possible routes that can lead to periodic compositional changes in chemical systems due to transport-driven instabilities, and related impacts on fundamental and applied problems.

Transport Phenomena in Chemical Flooding

SPE Advanced Technology Series, 1996
Abstract A chemical flood simulator of a three-component, two phase system has been extended to include concentration dependent functions: phase behavior, relative permeabilities, capillary pressure, interfacial tension, residual saturations, phase viscosities, wettability, etc..
