The aim of this study was to determine floristic diversity, the chemical composition, nature value and energy value of selected sedge communities in view of habitat conditions in the Noteć valley. This study was based on a total of 46 relevés prepared according to Braun-Blanquet. The identified communities were represented by common plant associations, both natural or semi-natural. They comprised...
Comparative studies of ipe (Tabebuia spp.) wood photodegradation caused by treatment with acid and alkaline buffers. A study on photodegradation of ipe wood using xenon lamp and UV lamp light has been carried out. Colour of the samples was measured using a Datacolour 600 spectrophotometer prior to their soaking in acid and alkaline buffers, after soaking and successively after 1, 5, 10, 25, 50 and...
Comparative studies of ipe (Tabebuia spp.) wood photodegradation cause by treatment with outdoor and indoor UV-A light irradiation. A study on photodegradation of ipe (Tabebuia spp.) wood by UV A light has been carried out. Two types of lamps were used in the tests, i.e. a UVA-340 lamp with a wavelength of 290 - 400 nm, emitting light resembling natural light, an a UVA-351 lamp with a wavelength of...
Lignocellulosic biomass is a natural, renewable and highly versatile resource.In recent years, woody biomass produced in short rotation coppices has become increasingly popular. Hence, this research was undertaken to assess the thermophysical and chemical properties of willow, poplar and black locust stems in relation to a soil fertilization regime. The experiment was set up in the village of Samławki...
