Temperature Dependence of the Viscoelastic Properties of a Natural Gastropod Mucus by Brillouin Light Scattering Spectroscopy [PDF]
, 2023 Brillouin spectroscopy was used to probe the viscoelastic properties of a natural gastropod mucus at GHz frequencies over the range -11 $^\circ$C $\leq T \leq$ 52 $^\circ$C. Anomalies in the temperature dependence of mucus longitudinal acoustic mode peak parameters and associated viscoelastic properties at $T = -2.5^\circ$C, together with the ...

Boreas, Volume 51, Issue 2, Page 385-401, April 2022., 2022 Large parts of the upper Midwest, USA were impacted by permafrost during the Last Glacial Maximum (LGM). Even though permafrost persisted as the Laurentide Ice Sheet began to recede, direct age control of this interval is largely lacking. To better temporally constrain the permafrost interval in western Wisconsin, we identified two sites, outside the ...

Multiscale mechanical study of the Turritella terebra and Turritellinella tricarinata seashells [PDF]
J. R. Soc., Interface 20 (205 ), 20230321 (2023 ), 2023 Marine shells are designed by nature to ensure mechanical protection from predators and shelter for mollusks living inside them. A large amount of work has been done to study the multiscale mechanical properties of their complex microstructure and to draw inspiration for the design of impact-resistant biomimetic materials.

Aquaculture Research, Volume 53, Issue 3, Page 782-798, February 2022., 2022 Abstract The ferruginous limpet is one of the most threatened invertebrate species in the Mediterranean Sea. Its controlled reproduction has been considered one of the potentially most effective strategies for the production of juveniles for population restocking or for recolonization of areas where the species was brought to extinction by human ...

Intracapsular embryogenesis and larval development of Chicoreus ramosus (Linnaeus, 1758) and Dendropoma platypus (Mörch, 1861) (Gastropoda, Prosobranchia) under normal and treated conditions [PDF]
, 2020 Samples of C. ramosus and D. platypus were collected from Hurgada, the Red Sea during June-August 2018. Samples were transported to the lab at the University of Alexandria, Egypt. This study aims to describe the embryogenesis of C.

Sedimentology, Volume 69, Issue 1, Page 345-371, January 2022., 2022 Abstract This paper regards the lower Pleistocene temperate‐water carbonate deposits disconformably overlying an escarpment made up of faulted Cretaceous to Miocene limestones of the Apulia Foreland (southern Italy). Study deposits discontinuously crop out along the present‐day eastern Salento sea cliff, and form isolated fan‐shaped bodies, up to 1 km ...

Biosurface and Biotribology, Volume 7, Issue 4, Page 233-238, December 2021., 2021 Abstract The purpose of this study is to achieve better understanding of associated mechanisms and to recommend and identify new strategies to develop new rock breaking technology for Tunnel Boring Machines (TBMs). Tunnel Boring Machine tunnelling mainly depends upon the rock breakage caused by cutters moving on a rock surface in a rolling and sliding ...

Journal of Quaternary Science, Volume 36, Issue 5, Page 805-832, July 2021., 2021 ABSTRACT Understanding the pace and drivers of marine‐based ice‐sheet retreat relies upon the integration of numerical ice‐sheet models with observations from contemporary polar ice sheets and well‐constrained palaeo‐glaciological reconstructions. This paper provides a reconstruction of the retreat of the last British–Irish Ice Sheet (BIIS) from the ...

Journal of Quaternary Science, Volume 36, Issue 5, Page 871-933, July 2021., 2021 Abstract Predicting the future response of ice sheets to climate warming and rising global sea level is important but difficult. This is especially so when fast‐flowing glaciers or ice streams, buffered by ice shelves, are grounded on beds below sea level. What happens when these ice shelves are removed?

Papers in Palaeontology, Volume 7, Issue 1, Page 521-564, February 2021., 2021 Abstract A diverse group of molluscs from the Cambrian Series 2, Stages 3–4 Xinji Formation of the North China Block (NCB) is described, based on more than 4500 specimens from three well‐studied sections in Shaanxi and Henan provinces, along the southern and southwestern margin of the NCB. Twenty molluscan species are identified, including one bivalve,
