Acetylation of European hornbeam (Carpinus betulus L.) wood for outdoor applications

, 2023
Many European wood species have low natural durability which makes them unable to be used for exterior applications without additional protection. In this work, European hornbeam wood (Carpinus betulus L.) was industrially acetylated in order to improve its properties and widen its usage.

Influence of Grit Size and Wood Species on the Granularity of Dust Particles during Sanding

Applied Sciences, 2020
Wood dust poses a threat to the health of employees and the risk of explosion and fire, accelerates the wear of machines, worsens the quality of processing, and requires large financial outlays for its removal.

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Hardness of thermally modified beech wood and hornbeam wood

Šumarski list, 2019
There is increasing number of products made of termally modified wood (mainly floor coverings) in wood market. Thermal modification at temperatures above 160 °C in oxygen free environment is known to alter the physical and mechanical properties of wood, among others.

Tvrdoća toplinski modificirane bukovine i grabovine

Šumarski list, 2019
Na tržištu se pojavljuje velik broj proizvoda (uglavnom podnih obloga) od toplinski modificiranog drva. Poznato je da se drvu mijenjaju fizička i mehanička svojstva djelovanjem temperatura viših od 160 °C u okolišu siromašnome kisikom. U prikazanom radu istraživana je promjena tvrdoće po Brinell-u toplinski modificirane bukovine i grabovine u odnosu na

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

CHANGES IN THE CHEMICAL STRUCTURE OF THERMALLY TREATED WOOD

BioResources, 2010
Changes in the chemical structure of hornbeam and uludag fir woods during thermal treatment were investigated at three temperatures (170, 190, and 210 oC) and three durations (4, 8, and 12 hours).

Investigation on the effect of wooden dowel diameter, penetration depth and species on the bending moment resistance under diagonal tensile load of corner joints in case-type furniture [PDF]

تحقیقات علوم چوب و کاغذ ایران, 2013
The bending moment resistance under diagonal tensile load of doweled joint in plywood members was investigated. Joint members were cut from 11-ply hardwood plywood (Beech, Hornbeam and Alder) at the nominal thickness of19 mm.
