TeachMe: a web-based teaching system for annotating abdominal lymph nodes.

The detection and characterization of lymph nodes through interpreting abdominal medical images are significant for diagnosing and treating colorectal cancer recurrence. However, interpreting abdominal medical images manually is labor-intensive and time-consuming. The related radiology education has many limitations as well.

[Study on quantitative analysis of cross linked copolymer by IR].

Cross linked copolymer silicon oil-Co-lactide (Si-co-LA) was analyzed quantitatively by IR. Potassium sulfocyanate (KSCN) was chosen as an inside mark material, because it has only one strong absorption peak at 2 100 cm(-1) and the peak was chosen as its quantitative peak. The peak at 1750 cm(-1) is the characteristic absorption of carbonyl and was chosen as thequantitative peak of lactide (LA).
