At first sight, “TRIANGLE” appears to be just another piece of learning software but it is much more than this, it is an experimental test-bed for examining motivational factors in computer based training. Such a multi-media application derives its power of attraction from the quality of the interface design and the multi-medial content. Used as a trial on a defined target group of K12-students...

An isolate of Aeromonas caviae 035 carried a 55.5 kb self-transferable plasmid. Transfer of the plasmid to Escherichia coli K12 resulted in the expression of a TEM-like beta-lactamase that was not expressed in parental A. caviae. The bla gene sequence was detectable by DNA hybridization and PCR amplification of the plasmid when extracted from parental A. caviae or from E. coli K12 transconjugan...

INTRODUCTION Osteosarcoma (OS) is the most common primary malignancy of bone. One-third of OS patients succumb to overwhelming pulmonary metastatic disease that is refractory to chemotherapy and surgery. Recent research suggests that bone morphogenetic protein (BMP) expression correlates positively with the incidence of OS pulmonary metastases and negatively with disease-free survival. Other re...

Treatment of Escherichia coli K12 C600 with colicin K or E1, but not E3, caused changes in the protein composition of the bacterial cytoplasmic membrane and an impairment of the membrane-associated ATP-linked transhydrogenase activity. The major compositional changes were loss and/or reduction in the levels of protein bands 4, 8, 9, 10, 13, and 18 with approximate molecular weights of 122,000, ...

⎯In this paper we investigate the capability of the genetic programming approach for producing hierarchical, rule-based, classification trees. These trees can be seen as an extension to the machine learning decision trees concept, where the predicates here can be complex expressions rather than just simple attribute-value comparisons. In order to improve the search ability and to produce meanin...
