Following compounds were determined in samples from Bransfield Strait and southern part of Drake Passage (area "A"): dissolved free- and combined amino acids, dissolved mono- and polisaccharides and urea. Concentration of urea in most samples ranges from traces to 1.5 μgat Nurea-1 and total urea content in water column from 10 to 150 m lies between 19.23 and 197.4 mgat Nurea . Dissolved free amino acids concentration ranges from 0 to 0.60μg x 1-1 and total free amino acid content are found to be between 20 and 60 mmol. Concentrations of combined amino acids lay below 7 μmol x 1-11 and integrated value for combined amino acids fluctuates between traces and 450 mmol. Monosaccharides concentrations in most samples do not exceed 2.5 μmol x l-1 and their content in water column lies below 180 mmol. Polysaccharides content in water column ranges from 1.8 to 3.94 mol and concentrations vary between 8 and 32 //mol-1 1. Evident differences in the content of dissolved organic compounds between Bransfield Strait and southern part of Drake Passage were found.
The paper provides analysis of the influence of temperature on the error of weigh-in-motion (WIM) systems utilizing piezoelectric polymer load sensors. Results of tests of these sensors in a climatic chamber, as well as results of long-term tests at the WIM site, are presented. Different methods for correction of the influence of changes in temperature were assessed for their effectiveness and compared.
The architectural and archaeological research conducted in 1977 was aimed at determining the stages of the church’s spatial development, which was to be achieved through analysis of its architecture, cultural accumulations, historical sources etc. During the research, eighteen coins were discovered — three early medieval ones and fifteen late medieval. The finds from St Elisabeth Church can be dated back to the period between the second half of the 13th century and the second half of the 14th century. The condition of some of the coins prevented complete identification. The discovered coins included Czech parvus coins (four), Wrocław city hellers (three) and other small coins which were in circulation at the time in Silesia.
