Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Rotational wood welding: Mechanical properties of thermally treated oak [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2022 The paper examined the strength of rotationally welded joints between untreated beech dowels and samples of thermally modified and unmodified oak wood (used as substrates). The results were compared with the control group where beech dowels were

Investigation of Welded Joints with Linear Turned Beech Elements [PDF]
, 2010 Welding of wood is a process where chemical and physical reactions take place, heat isformed during the friction, which melts and softens the structure of wood, and a firm joint is formedby cooling of the melt.The paper discusses the present knowledge ...

Influence of Various Wood Species and Cross-Sections on Strength of a Dowel Welding Joint
Drvna Industrija, 2014 Rotation welding is a new method used in wood welding. Heat that develops due to the friction on contact surfaces softens and melts the wood structure (melt is produced).

Influence of Biological Pretreatment of Wooden Dowels on Strength of Rotary Welded Joints
BioResources, 2023 Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin.
