Application of a TLC chemical method to detection of cyclotides in plants
Iodine, Dragendorff’s reagent, ninhydrin and Coomassie brilliant blue G-250 reagents were used to detect cyclotides from proteins, cyclopeptides, linear-peptides and amino acids in the thin layer chromatograph...

Numerical comparison of two boundary element methods for plane harmonic functions
A direct boundary element method (BEM) has been studied in the paper based on a set of sufficient and necessary boundary integral equations (BIE) for the plane harmonic functions. The new sufficient and necess...

Transition elements matching the near crack-tip strain field
New transition elements used with the collapsed triangular singular elements are constructed by using the improved isoparametric transformations. Without 1/r singular terms, the new transition elements' strain fi...
