Behaviour of a Harbour Seal (Phoca vitulina) Mother and Pups in a Zoo Setting [PDF]

open access: yesAnimals
Although harbour seals have often bred successfully in captivity, there is little information on the behaviour and welfare of captive mothers and their pups. This study used video of a mother with her newborn pup (P1) during the first 16 days post-partum

To seal or not to seal

open access: yesBritish Dental Journal, 2019
When an object impacts the free surface of a liquid, it ejects a splash curtain upwards and creates an air cavity below the free surface. As the object descends into the liquid, the air cavity eventually closes under the action of hydrostatic pressure (deep seal).

Mo content-depended competition between Cr2O3 enrichment and selective dissolution of CoCrFeNiMo x high entropy alloys

open access: yesnpj Materials Degradation, 2022
The corrosion and passivation behavior of the as-cast CoCrFeNiMo x (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0) high entropy alloys (HEAs) are investigated. With the addition of Mo, increasing Mo and Cr riched σ phase precipitates from the primary FCC phase. The
