A small-scale comparison of Iceland scallop size distributions obtained from a camera based autonomous underwater vehicle and dredge survey. [PDF]

PLoS ONE, 2014
An approach is developed to estimate size of Iceland scallop shells from AUV photos. A small-scale camera based AUV survey of Iceland scallops was conducted at a defined site off West Iceland.

Unveiling the unknown phylogenetic position of the scallop Austrochlamys natans and its implications for marine stewardship in the Magallanes Province

Scientific Reports, 2021
Two species of scallop, Austrochlamys natans (“Ostión del Sur”) and Zygochlamys patagonica (“Ostión patagonico”) are presently exploited in the southern part of the Magallanes Province (MP).

Scallop swimming kinematics and muscle performance: modelling the effects of "within-animal" variation in temperature sensitivity [PDF]

, 2005
Escape behaviour was investigated in Queen scallops (Aequipecten opercularis) acclimated to 5, 10 or 15 degrees C and tested at their acclimation temperature.

Method for Keyhole-Free High-Aspect-Ratio Trench Refill by LPCVD

Micromachines, 2022
In micro-machined micro-electromechanical systems (MEMS), refilled high-aspect-ratio trench structures are used for different applications. However, these trenches often show keyholes, which have an impact on the performance of the devices. In this paper,

A hybrid analytical and discrete based methodology to calculate path scallop of helical toroidal cutter in five-axis milling [PDF]

FME Transactions, 2018
This paper presents a new method to calculate path scallop height of toroidal cutter during free-form surface machining in five-axis milling. The scallop height was defined as the distance between the tool intersection point and the normal point on the ...

Temperature acclimatisation of swimming performance in the European Queen Scallop [PDF]

, 2005
The phenotypic plasticity of muscle performance and locomotory physiology allows the maintenance of essential activity capacity in the face of environmental change, and has been demonstrated in a wide phylogenetic range of eurythermal vertebrates.

Development of Novel Cardiac Indices and Assessment of Factors Affecting Cardiac Activity in a Bivalve Mollusc Chlamys farreri

Frontiers in Physiology, 2019
Cardiac activity has been widely used in marine molluscs as an indicator for their physiological status in response to environmental changes, which is, however, largely less studied in scallops.

Ultradian rhythms in shell composition of photosymbiotic and non-photosymbiotic mollusks [PDF]

Biogeosciences, 2023
The chemical composition of mollusk shells is a useful tool in (paleo)climatology since it captures inter- and intra-annual variability in environmental conditions. Trace element and stable isotope analysis with improved sampling resolution now allows in
