Solanum elaeagnifolium Cav. is one of the most invasive plant species worldwide that colonizes crops and human disturbed lands, while it appears at edge forest ecosystems. Its control still remains an unsolved problem around world. Understanding its distribution under predicted climate change, could contribute to effective management conservation ecosystems in future. This research was conducte...

results the results of the study, using the two methods, showed that all methanol extracts of leaves and fruits of the six species possessed antioxidant activity. the antioxidant activity of the samples was compared with the antioxidant activities of butylatedhydroxytoluene (bht), as a synthetic antioxidant and α-tocopherol as a natural antioxidant. methanol extractions of pinus spp. leaves and...

Red pine cone and barks combined with red pine wood particles in various proportions were used as the raw materials for one and three layered experimental particleboard manufacturing in laboratory conditions. The pine cones and barks have higher lignin, but lower holocellulose content compare to wood. For bark-based panels, the highest MOR (2.52 MPa) corresponded to the lowest thickness swellin...

The usability of lavender stems along with red pine chips was investigated as raw materials in the production of particleboard. Medium-density particleboard was manufactured using urea formaldehyde glue at three different ratios for five different mixture groups containing lavender stems and red pine chips. Some physical and mechanical properties of the boards were investigated. According to th...
