Purpose. To identify the peculiarities of landscape complexes regional park (RLP) «Murafa». Methods: theoretical generalization, systematization facts, finding empirical relationships, analytical and cartographic analysis, cartographic, logic, field. Results. Forest-steppe upland landscapes are widespread on territory RLP Murafa. Within them sloping, floodplain, floodplain-terrace, watercourse ...

As they descend, the autorotating seeds of maples and some other trees generate unexpectedly high lift, but how they attain this elevated performance is unknown. To elucidate the mechanisms responsible, we measured the three-dimensional flow around dynamically scaled models of maple and hornbeam seeds. Our results indicate that these seeds attain high lift by generating a stable leading-edge vo...

The contents of the colon of the Tyrolean Iceman who lived ca. 5300 years ago include muscle fibres, cereal remains, a diversity of pollen, and most notably that of the hop hornbeam (Ostrya carpinifolia) retaining cellular contents, as well as a moss leaf (Neckera complanata) and eggs of the parasitic whipworm (Trichuris trichiura). Based almost solely on stable isotope analyses and ignoring th...

In this research, hornbeam chips were cooked under chemimechanical pulp (CMP) conditions, and the pulps were prepared at a yield level of 85%. The CMP pulps were separately bleached with hydrogen peroxide and sodium dithionite with and without treatment with DTPA. Then 60 gr/m 2 handsheets were made. The goal was to determine whether complementary bleaching with sodium dithionite improves optic...

in this study, hydrophilic extractives of beech, maple, alder and hornbeam knots were isolated and characterized by means of gas chromatography - mass spectrometry (gc / ms). also, antioxidant activity of the extracts extractives was studied. hydrophilic compounds of the extractives were isolated by soaking the wood flour in the solvent. isolation was made using a hexane pretreatment for removi...
