The study investigated deformations, stresses and the character of changes induced by the non-free shrinkage of beech timber specimens (Fagus sylvatica L.) in the radial direction, in the conditions of varied drying intensity. During the experiments, the program of intense drying (T=60°C, EMC=10%) and the program of moderate drying (T=40°C, EMC=15%) have been taken into consideration, and the values...
Currently, the basic way of wood moisture content decrease control during drying process is measurement of that moisture content with resistance meters on a random selection of timber items. The results of that measurements are particularly unreliable, especially at wood moisture content below fibre saturation point and, on the other hand, they are influenced by accuracy of samples choice. Research...
The drying quality of kiln dried timber was verified in Polish sawmills and furniture companies. The estimation of the quality was limited to the mean moisture content after drying. The quality classes specified in the European Drying Group Recommendation were primary used in the analysis. The obtained results showed that sawmills might presently satisfy the S quality class, while the furniture...
Capsaicin and papaverine are potent vasorelaxants with strong gastroprotective activity against damage induced by absolute ethanol. This protection was originally attributed to the increase in gastric mucosal blood flow (GBF) but the possibility that NO mediates the protective and hyperemic effects of capsaicin and papaverine has been little studied. Using N-nitro-L-arginine (L-NNA), a selective blocker...
