Patterns of Ips cembrae (Herr) infestation on trap and standing trees of European larch (Larix decidua Mill.)
(Northeast Forestry University, 2023)
The large larch beetle, Ips cembrae, is a significant pest causing the death of larch. In 2020, the attack density of I. cembrae on larch trap trees and standing trees was evaluated using sample sections placed along the ...
Urban Forest Recreation and Its Possible Role throughout the COVID-19 Pandemic
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)
Urban forests provide benefits in terms of the environment and society. Many people living in urban areas could profit from the recreational services provided by urban forests to alleviate the physical and psychological ...
Appraising the dielectric properties and the effectiveness of electromagnetic shielding of graphene reinforced silicone rubber nanocomposite
(Walter de Gruyter GmbH, 2023)
The aim of this research is to measure the dielectric properties and electromagnetic interference (EMI) shielding effectiveness (SE) of silicone rubber reinforced with graphene nanoplates. In a two-roll mill, different ...
Synthetic leathers as a possible source of chemicals and odorous substances in indoor environment
(De Gruyter Open Ltd., 2023)
This article deals with volatile organic substances (VOCs) and odours that can be released into the indoor environment from synthetic leathers that are part of upholstered furniture. The primary task of this study was to ...
Artificial Weathering Resistance and Biological Durability of Surface-Charred Beech Wood Combined with Linseed Oil Coating
(North Carolina State University, 2023)
Specimens of European beech wood (Fagus sylvatica L.) charred at 250 oC (4 min), 300 oC (2 min), and 350 oC (1 min) in combination with linseed oil coating were studied. The influence of the surface charring process and ...
Phytophthora, Nothophytophthora and Halophytophthora diversity in rivers, streams and riparian alder ecosystems of Central Europe
(Springer Heidelberg, 2023)
Waterways are ideal pathways for Phytophthora dispersal and potential introduction to terrestrial ecosystems. While many Phytophthora species from phylogenetic clades 6, 9 and 10 are predominant oomycetes in watercourses ...
Fomes fomentarius and F. inzengae-A Comparison of Their Decay Patterns on Beech Wood
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)
Wood-decaying fungi are responsible for the degradation of wood and the alteration in its material properties. Fomes fomentarius (L.) Fr. is one of the most common white-rot fungi colonising coarse wood and standing trees. ...
Development of Douglas fir merchantable stem volume model in the conditions of the Czech Republic
(Česká akademie zemědělských věd, 2023)
A precise merchantable stem volume model of Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] is missing in the Czech Republic. The aim of this study was to fit a new model through the reparametrization of volume equations ...
Properties of lightweight particleboard made with sunflower stalk particles in the core layer
(Elsevier Science BV, 2023)
In this study we assessed the efficacy of manufacturing lightweight particleboards using sunflower (Helianthus annuus L.) stalk particles. Three-layer lightweight particleboards with target densities of 350, 450 and 550 ...
Effect of different stand densities on xylem and phloem formation in Norway spruce plantations
(Brill, 2023)
Preliminary results of an investigation of the thinning effect on Norway spruce tree growth in terms of xylogenesis and phloemogenesis are presented. Three plots were selected where the stand densities were reduced by ...
