A SERIES of fluorescent pteridines may be revealed and separated by paper chromatography (Hadorn & Mitchell, 1951) from various organs of Drosophila in which they appear in high concentrations. Striking differences in the quantities and in the developmental patterns of these compounds are produced by a variety of gene mutations. While the chemical analysis of the fluorescent substances is rapid...

Working memory capacity (WMC) is a cognitive characteristic that affects students’ learning behaviors to perform complex cognitive tasks. However, WMC is very limited and can be easily overloaded in learning activities. Considering students’WMC through personalized learning materials and activities helps in avoiding cognitive overload and therefore positively affects students’ learning. However...

BACKGROUND The risk factors for developmental dysplasia of the hip (DDH) in infants from unifetal pregnancies are commonly known. Many of these factors also apply to multiple pregnancies. The aim of this paper was to evaluate the influence of selected, widely recognized DDH risk factors in unifetal pregnancy on the development of hip joints in infants from multiple pregnancies. The following ri...
