During the course of research, the extractability of various phenolic compounds were analysed in ‘Blaufraenkisch’ berry skins and wines produced by six types of vine load. A sample of the berry skin was detached from the harvested crop and following the extraction with hydrochloric acid-methanol the composition of the extractive and the wines prepared by microvinification was analysed. During the course of the tests, the total polyphenolic-, anthocyanin-, leucoanthocyanin- and catechin content of the samples were measured by the application of the spectrophotometric method. Based on the measured data, the extraction coefficients (EC %) were calculated for each vine load, and then through the application of statistical methods, the data of three vintages were evaluated. The results revealed that extractability does not necessarily depend on the method of cultivation or the vine load. No significant differences were found pertaining to either the extractability of the total polyphenolic-, leucoanthocyanin- or catechin content. However, the extraction coefficient of the anthocyanins in crops produced by cluster selection and cane-based cultivation was significantly lower than in the cluster-selected crops of vine-stocks with less bud load.

Abstract

Nowadays the facades of newly built buildings have significant glazed surfaces. The solar gains in these buildings can produce discomfort caused by direct solar radiation on the one hand and by the higher indoor air temperature on the other hand. The amplitude of the indoor air temperature variation depends on the glazed area, orientation of the facade and heat storage capacity of the building. This paper presents the results of a simulation, which were made in the Passol Laboratory of University of Debrecen in order to define the internal temperature variation. The simulation proved that the highest amplitudes of the internal temperature are obtained for East orientation of the facade. The upper acceptable limit of the internal air temperature is exceeded for each analyzed orientation: North, South, East, West. Comparing different building structures, according to the obtained results, in case of the heavy structure more cooling hours are obtained, but the energy consumption for cooling is lower.
