Distribution of selected substances in blue varieties of table grapes

This study contains data of seven blue cultivars of table grape (Vitis vinifera L. and Vitis labrusca L.): Attika, Early Cardinal, Eszter, Chasselas rosé, Königliche Esther, Muscat bleu, and Nero. The following were determined in intact berries: malic, tartaric, and titratable acids, pH values, sugar content, and antioxidant capacity. Concentrations of the following compounds were determined in the pulp of a analysed berries: phenolic acids and catechins. The last analysis focused on skins; in addition to the same phenolic acids and catechins, excluding epicatechin, analysed from pulp; ferulic acid and stilbenes were also studied. Higher contents of procyanidin B2 and gallic acid were found in the pulp as compared to those found in skins. Studies during the ripening stage showed that the higher ratio of procyanidin B2 and gallic acid concentrations in the pulp vs. skins relates to late-ripening cultivars, while for early-ripening cultivars a lower ratio was observed. Contents of phenolic acids, catechin, stilbenes, and anthocyanins were studied by means of LC-DAD; other compounds were measured by FTIR

Methodology of the Principles of Rehabilitation of Cultural Heritage Buildings

The aim of the presented methodology is to summarize the rehabilitation principles that can be applied in the context of the repair of historic buildings. The methodology defines the fundamental influences that affect the approach to rehabilitation and also specifies the individual steps that are part of the actual implementation. Attention is paid to three basic areas of rehabilitation measures. These are addressing moisture and related problems, modifying the indoor microclimate, and restoring or strengthening the structural function of the building. Concerning conservation aspects, the principles presented are directed predominantly towards conserving and prolonging the life of the existing structural elements, taking into account future use and operation. The preservation of the original forms and functions of the individual structures is pursued as far as possible. The target group of users of this methodology is conservation officers, designers, owners, and managers of historic buildings. The methodology provides these users with the basic information for initiating the restoration of monuments
