When culturing the pileitrama of young fruit bodies of the two mycoparasitic agarics, Asterophora lycoperdoides (Bull.: Fr.) Ditmar and A. parasitica (Bull.: Fr.) Singer, two tremelloid yeasts were detected (Laaser et al., 1988, 1989; Prillinger, 1987a). The term tremelloid was suggested by Oberwinkler (Laaser et al., 1988; Oberwinkler pers. comm.) for budding yeasts having a cup-shaped parenth...

In these notes we discuss a paper of Gupta, Roughgarden, and Seshadhri, “Decompositions of Triangle-Dense Graphs” [1]. The motivation of the paper is to develop a theory of algorithms for social networks, like the graphs derived from Facebook or Twitter data mentioned in the first lecture. That is, the goal is to develop graph algorithms that work well on social networks, if not on worst-case g...

Cryptosporidium and Giardia are 2 protozoan parasites responsible for waterborne diseases outbreaks worldwide. In order to assess the prevalence of these protozoans in drinking water samples in the northern part of Portugal and the risk of human infection, we have established a long term program aiming at pinpointing the sources of surface water, drinking water, and environmental contamination,...

In this study T helper cells that recognize idiotypes as carriers for a hapten-specific B cell response were analyzed under limiting dilution conditions. T helper cells, induced by phosphorylcholine-hemocyanin (PC-Hy) priming, recognize trinitrophenylated TEPC-15 and MOPC-167 (TNP-T15, TNP-167) equally well. Limiting dilution analysis indicates identical frequencies of helper cells for TNP-T15 ...
