A General Synthesis for Mono- C -Functionalized Tetrazamacrocycles A new synthesis, under usual conditions of concentration, medium, and temperature, of a series of mono- C -functionalized tetraazamacrocycles is given. The method may easily be generalized. The new procedure allows the modification ...

Vigna benuensissp. nov. from north Cameroon is described. It is closely related toVigna ambacensisvar.pubigera, but is amphicarpic and shows slight differences in floral morphology and size. Some important morphological features are compared with those of its allied species....
This thesis does such a factorization for theoretical type systems featuring recursive types, subtyping, bounded polymorphism, and constraint polymorphism. Interestingly, soundness and normalization for strong reduction imply soundness and normalization for all usual strategies. Our observation is that a ...

These U. R. Represent a tool that leads to make ergonomics considerations during the design. Secondly, we use task models to integrate MIS interaction in the user activity, and MIS interaction models to describe their complexity.Connor, SteveBibliogr...
To explain this evolution of music, we study the emergence of sound - which has no affinities with timbre - in contemporary music (1950-60) and more precisely, in the first works of Xenakis. We begin with the fact that the traditional categories of tone, rhythm, language and form are ...
