Yangın geciktirici kimyasallar, uygulanmış oldukları malzemelerin fiziksel, mekanik ve diğer bazı teknolojik özellikleri üzerinde farklı etkilere neden olmaktadır. Bu etkiler, çözeltilerin konsantrasyon miktarlarına retensiyon bağlı olarak değişim gösterebilmektedir. yüzden, yangın kimyasalların uygulandıkları malzemeleri kullanım yerlerinde istenilen özelliklere göre en az seviyede olumsuz etk...

Non-native nitrogen-fixing Acacia species have been invading riparian ecosystems worldwide, potentially threatening stream communities that strongly depend on allochthonous litter. We examined the effects of invasion native deciduous temperate forests by litter decomposition and associated fungal decomposers in streams. Litter (Alnus glutinosa Quercus robur) invasive (Acacia melanoxylon) were e...

Moisture content (MC) is one of the most important factors that can affect many physical and mechanical properties of wood and veneers. MC strongly affects the final strength and durability of joints, development of surface checks in the wood and dimensional stability of the bonded assembly. In this study, plywood panels made from Alnus glutinosa (Alder), Fagus orientalis (Beech) and Picea orie...

In Alaska, an unprecedented dieback and mortality of Alnus incana ssp. tenuifolia has occurred which stimulated an effort to determine causal agents of the disease. In Europe, similar dieback and mortality of Alnus incana and Alnus glutinosa has been attributed to root rot by a spectrum of newly emergent strains in the hybrid species Phytophthora alni. The variable hybrids of P. alni were group...

Phenological time series of flowering and bud burst of Populus tremula (L.) and Betula sp., and the flowering of Pinus sylvestris (L.), Alnus glutinosa (L.) and Alnus incana (L.) were constructed from data collected in Finland during the period 1896–1955. The resulting combined time series were examined with two aims in mind: first, to determine the phenological regularities between different s...

There are four alder species native to Europe: the common alder (Alnus glutinosa), the grey alder (A. incana), the Italian alder (A. cordata) and the green alder (A. viridis). In general, members of the genus Alnus are pioneer species, able to colonise bare, open ground rapidly and with a great ability to tolerate wet sites. The roots have specialised nodules which fix atmospheric nitrogen as a...
