In this study is to examine the effect of industrial heat treatment application on dimensional stability and dynamic wettability properties ash (Fraxinus excelsior) wood. Ash samples that were treated for 120 minutes at 210 degrees according ThermoWood process used. study, a total 30 samples, including 15 with dimensions 20x20x30 mm, unheat cut examined. The results obtained in showed property ...

A sustainable, fast, feasible, and controlled approach is reported for the synthesis of silver nanoparticle (AgNP). The extract from natural ash plant (Fraxinus excelsior) flower was used as bio-based reducing stabilizing agent to synthesize AgNPs AgNO3 precursor. quantitative analysis AgNP performed by X-ray fluorescence (XRF) inductively coupled plasma optical emission spectroscopy (iCP-OES) ...

Abstract Hymenoscyphus fraxineus, causal agent of Ash Dieback, has posed a threat to Fraxinus excelsior (common ash) in Europe since the 1990s. In south-western Europe, optimal climatic conditions for H. fraxineus become scattered and host density decreases, reducing disease spread rates . To date, Dieback not been reported from southern most central Italy, where native F. is present as small f...

Prociphilus fraxinifolii (woolly ash aphid) is a pest of trees (Fraxinus spp.). This species, which native to North America, was first recorded in Europe 2003, Budapest, and then began spread quickly. In 2019–2021, we detected P. Belarus (Brest) eight regions European Russia, namely Astrakhan, Nizhny Novgorod, Samara, Saratov, Smolensk, Tambov, Volgograd Voronezh regions. By 2021, has over vast...

У насадженнях Містківського лісництва ДП «Сватівське ЛМГ» Луганського ОУЛМГ досліджували динаміку вильоту жуків ясенової смарагдової вузькотілої златки (ЯСВЗ) з модельних дерев ясена звичайного (Fraxinus excelsior) та зеленого (F. pennsylvanica), зокрема звичайного, відібраних у сухому свіжому груді. Перші льотні отвори виявлено 14 червня, а останні – 4 липня на деревах обох видів ясена. Динамі...

specific features of the structure of the ground litter invertebrate community in forest belt ecosystems in the ukrainian steppe zone have been considered. for 14 years invertebrate fauna of the litter of 176 forest belt sites with different composition has been studied with the aid of soil traps. the main characteristics of litter invertebrate communities (total population, a number of species...
