Variation of Equilibrium Moisture Content of Heat- treated Couratari oblongifolia, Fraxinus excelsior, and Quercus rubra wood
Heat treatment may result in variation of wood equilibrium moisture content (EMC). During this study, tauari (Couratari oblongifolia), ash (Fraxinus excelsior), and oak (Quercus rubra) woods were heat-treated at 190, 200, and 210oC for 3 hours and then put into a conditioning chamber with a temperature from 30 to 75oC and a relative humidity from 50 to 90%. The isothermal moisture adsorption cu...
متن کاملGenetic Characterization of Common ash (Fraxinus excelsior L.) populations in Bosnia and Herzegovina
Background and Purpose: Common ash (Fraxinus excelsior L.) is a species with a widespread distribution in Europe. It mostly grows on mesophyll sites, mainly in karst valleys and by forest creeks, and in Herzegovina at northern expositions and higher altitudes with somewhat better types of soil. Materials and Methods: We studied 10 natural populations. We collected dormant buds with branches fro...
متن کاملApplication of ash (Fraxinus excelsior L.) roots to determine erosion rates in mountain torrents
Due to the effect of global change, the potential risk of natural hazards occurring in alpine areas is expected to increase to an even higher risklevel than has been recorded during the last century. These global changes potentially also have distinct influences on fluvial processes in torrents causing erosion on slopes and riverbanks in forested areas. Dating the time of root exposure along ri...
متن کاملGene flow of common ash (Fraxinus excelsior L.) in a fragmented landscape
Gene flow dynamics of common ash (Fraxinus excelsior L.) is affected by several human activities in Central Europe, including habitat fragmentation, agroforestry expansion, controlled and uncontrolled transfer of reproductive material, and a recently introduced emerging infectious disease, ash dieback, caused by Hymenoscyphus fraxineus. Habitat fragmentation may alter genetic connectivity and e...
متن کاملLong-Term Effect of an Aqueous Fraxinus excelsior L. Seed Extract in Spontaneously Hypertensive Rats
The effect of long-term intake of different doses (20, 40, and 60 mg/kg/day) of a Fraxinus excelsior L. seed extract (FESE) on spontaneously hypertensive rats (SHR) was evaluated. Water was used as control and captopril (50 mg/kg/day) was used as positive control. Systolic blood pressure, body weight, and food and liquid intake were registered weekly in SHR. The antioxidant and vascular relaxin...
