Crease‐Encoded Soft Origami Chambers: A Unified Design‐to‐Fabrication Framework for Low‐Pressure Pneumatic Joints

Advanced Intelligent Systems, EarlyView.
Origami turns a single silicone chamber into three different soft fluidic actuators. Crease angles alone decide whether it elongates, bends, or twists, and the fully folded chambers are cast monolithically in one day. Below 15 kPa, they reach 268% axial stretch, 72° bending, and 55° twist—no strain‐limiting layers, no rigid reinforcements, no vacuum ...

Radionuclides in grey seals

Marine Pollution Bulletin, 1990
Milk from live female grey seals (Halichoerus grypus) and tissues from dead individuals were analysed for caesium isotopes and for plutonium and americium. The samples were collected at two sites, one in the North Sea and one in the north-east Atlantic.

Immobilization of Grey Seals

The Journal of Wildlife Management, 1965
To immobilize grey seals (Halichoerus grypus) for marking, the Cap-Chur gun was used with two analogues of succinylcholine-suxamethonium, the methyl derivative, and suxethonium, the ethyl derivative. A modified needle was developed to hold in the seals' hide even when the syringe struck at an angle. Experiment determined that an effective dosage of the

Longevity in the Grey Seal

Nature, 1950
HAVING had occasion recently to consult the late Major S. S. Flower's paper1 on the duration of life among mammals, I notice that data regarding the Phocidae (apart from Phoca vitulina) are extremely scanty. The only information given about the grey seal, Halichaerus grypus, is that one (sex unspecified) “is known to have lived for a very long time in ...
