Gene expression microarrays allow the quantification of transcript accumulation for many or all genes in a genome. This technology has been utilized for a range of investigations, from assessments of gene regulation in response to genetic or environmental fluctuation to global expression QTL (eQTL) analyses of natural variation. Current analysis techniques(More)
The q-deformed commutation relation aa ? qa a = 1 1 for the harmonic os-cillator is considered with q 2 ?1; 1]. An explicit representation generalizing the Bargmann representation of analytic functions on the complex plane is constructed. In this representation the distribution of a + a in the vacuum state is explicitly calculated. This distribution is to(More)
Plant genomes contain numerous genes (R-genes) that play a role in initiating defence measures against their particular pathogens. Defence mechanisms controlled by R-genes have been the focus of extensive research over the past several years. The majority of the R-genes described so far belong to a super-family of genes (150–600 members) that encode(More)
A bacterial artificial chromosome (BAC) library from the dihaploid melon line `PIT92' was constructed with a 6 times coverage of the haploid melon genome. A contig of four BACs around the MRGH63 resistance gene homologue fragment was created. The complete sequence of a 117-kb BAC clone allowed to determine two clearly defined regions, the first one(More)

Within the frame of the project GeoBIRD (ESA contract 12950/98/NL/GD entitled "Retrieval of geoand bio-physical information from remote sensing data") an attempt was made to derive soil moisture by combining the microwave remote sensing model CLOUD and the land surface process model PROMET-V (PROcess oriented Modular Environment and Vegetation model.

Public concerns about offensive odor from livestock operations are on the rise, bringing up an increasing demand on odor treatment. In this work, a bench-scale standard gases generation and UV treatment system was built up, where standard gas mixtures including sulfuric compounds (H2S, methylmercaptan, ethylmercaptan, DMS and butylmercaptan), volatile fatty(More)
