This paper presents TrAVis (Tracking Data Analysis and Visualization Tools), a Web-based system, implemented to assist the participants in the learning process in analyzing the tracking data of ComputerMediated Communication activities. While most of the existing systems in the same genre are exclusively dedicated to the teachers and only a few are accessible by students, TrAVis is objectively ...

Hedgehog (Hh) proteins signal by inhibiting the proteolytic processing of Ci/Gli family transcription factors and by increasing Ci/Gli-specific activity. When Hh is absent, phosphorylation of Ci/Gli triggers binding to SCF ubiquitin ligase complexes and consequent proteolysis. Here we show that multiple successively phosphorylated CK1 sites on Ci create an atypical extended binding site for the...

Freshman and Sophomore classes, sex groups, and age groups. We did not attempt (as Travis2 did) to discover whether the test gave satisfactory results for individuals. For in order to gauge the intelligence of individuals it is generally agreed3 that one kind of test alone is insufficient, and that a series of different tests give better results; and in the second place, tests given to classes ...

A new chitinase inhibitor, CI-4, was isolated from the culture broth of a marine bacterium Pseudomonas sp. IZ208. The structure of CI-4 was determined to be cyclo(L-Arg-D-Pro) by spectral studies and comparison with a synthetic sample. CI-4 showed inhibitory activity against chitinase.
