In this study, the behavior of tannin-modified and pre-heat treated wooden beams in different climatic conditions were determined. For purpose; Samples prepared according to TS EN 386 standards from Scots pine (Pinus sylvestris L.), oak (Quercus petraea L.) chestnut (Castanea sativa Mill.) woods impregnated with acorn tannin pre-heated for 2 hours at 150°C 160°C.

Scotch pine. input parameters were duration and concentration monoethanolamine solution. experimental data processed using STATGRAPHICS® Centurion software package. It has been established that maximum extractive substances occurs when is 5 hours with a 5%.
The age of the Universe depends on both the present-day Hubble Constant and on the history of cosmic expansion. For decelerating cosmologies such as Ω m = 1, the dimensionless product H 0 t 0 < 1 and modestly high values of the Hubble constant H 0 > 70 would be inconsistent with a cosmic age t 0 larger than 12 Gyr. But if Ω Λ > 0, then H 0 t 0 can take on a range of values. Evidence from the Hu...
