Bestrijding van Phoma in Sedum

In het gewas Sedum kan de schimmel Phoma telephii veel schade aanrichten. Phoma kan als een sluipmoordenaar in het gewas te gaan werken en is in staat om het gehele gewas te vernietigen als niet direct een goede bestrijding van de schimmel wordt uitgevoerd. Omdat de toelating van het middel Topsin M is ingetrokken, is gezocht naar nieuwe middelen voor de bestrijding van deze hardnekkige schimmel in de bloementeelt van Sedum

Educating "Modern Mind" in the Light of the Evolution of Western Educational Thought

My thesis is that liberal and progressive education models respectively refer to dual and unitary conceptions of intellectual development, and that these differences account for their pedagogical antagonisms. I test the validity of this argument by using it to account for the evolution of Western pedagogy and the fate of liberal and progressive education. I introduce the dualist epistemological premises of the major educational models that have followed one after the other in the history of Western education. Then, I account for the impact of classical empiricism, and later evolutionary doctrines, on the discredit of liberal education and the emergence of educational progressivism. Progressive educational conceptions are rooted in a representation of humankind developed under the influence of the Darwinian revolution. They justify an adaptive model of the mind within the framework of a functionalist psychology. According to alternative currents of modern educational thought, the use of auxiliary means of thought marks a rupture with human biological development. These currents underpin a dual conception of human reason according to which rational or theoretical understanding is a sui generis dimension of thought. They offer support for a modernized version of liberal education

Escherichia coli as a potential hydrocarbon conversion microorganism. Oxidation of aliphatic and aromatic compounds by recombinant E. coli in two-liquid phase (aqueous-organic) systems

The increased interest in the study of hydrocarbon utilizing microorganisms in recent years has been stimulated by the possibility of using their monooxygenases in the selective oxidation of aliphatic and aromatic compounds. As an example, long chain (>C16) n-alkanes are converted to dicarboxylic acids by yeast. This type of bioconversion is useful because the regioselective and stereospecific introduction of oxygen into unactivated organic substrates by classical synthetic chemistry remains very difficult.
