Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions

The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. Femtosecond laser spectroscopy has been employed as t

Numerical and Experimental Studies on the Effects of Flow on Drop Formation in Cross-flow Membrane Emulsification

Membrane emulsification is a gentle process that produces emulsions with a narrow drop size distribution, which increases the stability of the emulsion. The dispersed phase is forced through the pores in a membrane and drops are formed at the other side of the membrane where a continuous phase, flowing along the membrane surface, sweeps away the forming drops. The growth and detachment of drops is

Abstract in DanishIt is the aim of this article to show how some cancer patients get caught in the so called welfare system of Denmark, simply because they have become too physically and/or mentally ill to meet the legal requirements of employment. Based on sociological analysis of a number of interviews, three cases are constructed. The analyses only take a user perspective. They show how, depend

Prohibition:negative imperatives and the parametric typology of negation

A number of researchers have offered hypotheses about the syntactic relationship between Tense and Negation. Zanuttini 1996, for example, has argued that the head NEG may only occur in the presence of Tense. This paper examines data on negation in 15 languages which has been collected in an ongoing typological research project, PARATYP. The study focuses on the difference between prohibitive and n
