The influence of low-frequency electromagnetic field on the operability of gray seals
Gray seals are widely used in biotechnical systems for various purposes. In the study of the effect of an artificial electromagnetic field (EMF) with 8 Hz frequency on the performance of gray seals, the method of conditioned reflexes has been used (one ...

Oil seal surface defect detection using superpixel segmentation and circumferential difference
Surface defects affect the quality and safety of oil seals. It is a challenge to detect such defects in a vision system because of the unequal reflection property of oil seal surfaces and low contrast between the defect and the background.

Phocid seal leptin: tertiary structure and hydrophobic receptor binding site preservation during distinct leptin gene evolution [PDF]
The cytokine hormone leptin is a key signalling molecule in many pathways that control physiological functions. Although leptin demonstrates structural conservation in mammals, there is evidence of positive selection in primates, lagomorphs and ...
