Trends in pig product processing at British Neolithic Grooved Ware sites traced through organic residues in potsherds

open access: yesJournal of Archaeological Science, 2008
Abstract Gas chromatography (GC), GC-mass spectrometry (GC-MS) and GC-combustion-isotope ratio MS (GC-C-IRMS) analyses of absorbed and surface lipid residues preserved in potsherds were used to explore the extent of pig product processing exploitation in the later British Neolithic Grooved Ware tradition.

Antler Mace Heads from Zvejnieki (Latvia) and the Changing World of Hunter-Fisher-Gatherers in the 4th Millennium BCE

open access: yesActa Academiae Artium Vilnensis
The starting point of this article is three so-called grooved mace heads, made of elk antler beams and found in burial 221 at the Zvejnieki cemetery in Latvia. Their best counterpart – a mace head crafted from a white quartzite pebble – was recovered

Fire and memory: transforming place using fire at henge monuments [PDF]

open access: yes, 2017
Henges — Late Neolithic to Early Bronze Age earthwork monuments — often have long life-histories of reuse and rebuilding over generations. At some sites, fire-lighting and the deposition of fire-altered materials played a significant role in certain ...

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
