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 ...

A retrospective analysis of 98 patients, less than 15 years of age, treated for caustic ingestion during 1976-1990 was performed to evaluate the modern consequences of caustic ingestion in children and to set indications for esophagoscopies and radiographic and laboratory examinations. Dishwasher detergents were ingested by 56 children. There were no lye ingestions, since lye has not been freel...

BACKGROUND/AIMS Sex hormones may influence the activity of enzymes which are involved in the synthesis of long-chain polyunsaturated fatty acids. The objective of this review was to assess the role of gender in determining the fatty acid composition of human samples, like plasma and erythrocyte membrane lipids, and adipose tissue. METHODS The method included a structured search strategy on ME...

BACKGROUND Randomized trials have largely failed to support an effect of antioxidant vitamins on the risk of cardiovascular disease (CVD). Few trials have examined interactions among antioxidants, and, to our knowledge, no previous trial has examined the individual effect of ascorbic acid (vitamin C) on CVD. METHODS The Women's Antioxidant Cardiovascular Study tested the effects of ascorbic a...

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...

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

Periodic acid-Schiff staining, acid phosphatase localization, and yellow autofluorescence have been correlated with the PAS-body of Gonyaulax polyedra for the first time. PAS- staining and acid phosphatase activity are both correlated with the PAS-body of Gonyaulax tamarensis. These results that the PAS-body of these marine dinoflagellate algae functions in subcellular digestion.

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 ...
