The pea chloroplastic outer envelope protein OEP24 can function as a general solute channel. OEP24 is present in chloroplasts, etioplasts, and non-green root plastids. The heterologously expressed protein forms a voltage-dependent, high-conductance (Lambda = 1.3 nS in 1 M KCl), and slightly cation-selective ion channel in reconstituted proteoliposomes. The… (More)
A relevant part of the quantum algebra of observables for the closed bosonic strings moving in 1 + 3–dimensional Minkowski space is presented in the form of generating relations involving still one, as yet undetermined, real free parameter.
We examine and implement the concept of non-additive composition laws in the quantum theory of closed bosonic strings moving in (3 + 1)-dimensional Minkowski space. Such laws supply exact selection rules for the merging and splitting of closed strings.
The purpose of the present paper is the communication of some results and observations which shed new light on the algebraic structure of the algebra of string observables both in the classical and in the quantum theory. A suitable introduction to the construction and investigation of the algebra of observables of the Nambu-Goto string in D-dimensional… (More)
The study presents the effects that different rearing methods of commercial pheasantries have on pheasants. The techniques applied by 17 commercial pheasantries in Northern Germany are specified. These techniques were exemplarily simulated on pheasants reared under defined conditions in special aviaries. The results illustrate the impact of the different… (More)
