CONSTITUTIVE MODEL FOR TIMBER FRACTURE USED FOR FE SIMULATION OF LVL ARCH

Acta Polytechnica CTU Proceedings, 2018
Non-linear finite element simulation of four-point bending test of a small-size arch is described in this paper. The arch of 780mm span is made of Yellow Poplar (Liriodendron tulipifera) laminated veneer lumber (LVL) and it is manufactured with a through

Fungicidal Efficacy of Leaf Extracts From Khaya senegalensis (Desr.) A. Juss. Irrigated With Agricultural Drainage Water and Treated With Some Fertilizer Types

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
The extraction and analysis of K. senegalensis compounds for wood preservation. Air‐dried leaves are milled, soaked in ethanol, filtered, and concentrated into dried extracts. These extracts undergo HPLC for chemical profiling. The concentrated extract is applied to wood samples to test its antifungal activity, demonstrating its potential as a natural ...

Intra-ring compression strength of low density hardwoods

Maderas: Ciencia y Tecnología, 2014
Engineered wood composites are being crafted with increasingly smaller and smaller components, yet a search of the literature indicates a lack of intra-ring mechanical property data for almost all commercial wood types, particularly the underutilized low

Intensive arable farming calls for resilient wild bee restoration amid severe abundance fluctuations

Ecological Applications, Volume 36, Issue 6, September 2026.
Abstract Intensive arable farming threatens wild bees by reducing floral and nesting resources, increasing agrochemical exposure, and amplifying climatic stress. Ecological restoration using native wildflower mixtures is a promising intervention to recover pollinator diversity and the ecosystem service of pollination.

Spider (Araneae) Abundance and Diversity Across Land‐Use Gradients

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We sampled spider populations in economically important kiwifruit orchards that are adjacent to either low‐disturbance ecosystems (native forest) or high‐disturbance ecosystems (maize), using pitfall traps and active sampling. A total of 2710 spiders were collected from 27 families, representing 64 species and eight functional guilds.

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...

Pangenome of Streptomyces sampsonii and Relatives Highlights Horizontal Gene Transfer and Secondary Metabolism in Environmental Adaptation and Ecological Significance

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study presents a chromosome‐level genome assembly of Streptomyces sampsonii and a pangenome analysis of 95 strains, revealing a highly expansive “open” pangenome. Our results highlight that horizontal gene transfer (HGT) and accessory gene variations drive the evolution of secondary metabolism and environmental adaptation.

Analysis of Micronized Charcoal for Use in a Liquid Fuel Slurry

Energies, 2016
Yellow poplar (Liriodendron tulipifera) was chosen as the woody biomass for the production of charcoal for use in a liquid fuel slurry. Charcoal produced from this biomass resulted in a highly porous structure similar to the parent material.
