Experiments in extrusion, Part 1 - review of the theories of extrusion.

open access: yes, 1964
The theories of extrusion are examined; considerable limitations exist in the analysis of extrusion conditions using either the semi-empirical approach, which is based on the assumption of homogeneous straining, or the slip-line approach.

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 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.

MultiRec: Effects of multiple extrusion in cast and blown film applications

open access: yes
The MultiRec project investigates the degradation of physicochemical and mechanical properties in linear low-density polyethylene granulate subjected to multiple reprocessing cycles without intermediate additivation. This reprocessed granulate is incorporated into stretch films for automatic wrapping.

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly
