During 1983-88 Aedes aegyptiwerc collected using larval surveys and ovitraps in Tobago, W.I. The main artificial containers used by Ae. aegypti were drums (35.4%) and small miscellaneous containers (23.4%). From a total of 15,600 ovitraps exposed, 183 ovitraps (1.3%) were positive, with 25 containing Ae. aegypti eggs and 158 with Haemagogus equinus eggs. No Aedes albopict&s eggs were detected i...

We prove two extensions of the Hales-Jewett coloring theorem. The first is a polynomial version of a finitary case of Furstenberg and Katznelson’s multiparameter elaboration of a theorem, due to Carlson, about variable words. The second is an “idempotent” version of a result of Carlson and Simpson. MSC2000: Primary 05D10; Secondary 22A15. For k,N ∈ N, let W k denote the set of length-N words on...

Over the last years a number of bioinformatic software programs have been developed in the area of molecular biology. The application of these bioinformatic tools to the wealth of existing transcriptomic and proteomic data can be used to predict the structure and hierarchy of signalling pathways and gene networks. In genetically tractable model organisms such as Arabidopsis thaliana, these hyph...
