Seals protect brain, conserve oxygen by turning off shivering response on icy dives
Seals shiver when exposed to cold air but not when diving in chilly water, a finding that researchers believe allows the diving seal to conserve oxygen and minimize brain damage that could result from long dives. The researchers presented the study at The American Physiological Society's conference "Comparative Physiology 2006: Integrating Diversity," in Virginia Beach, Va., October 8-11....Female Antarctic seals give cold shoulder to local males
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males. These findings, published in this week's Nature, suggest that female choice may be more widespread in nature than previously believed and that such strategies enable species to maintain genetic diversity. Scientists from the...Crimp Seals with PTFE/Rubber Septa from Sigma-Aldrich
Description:11 mm seal diam....F40 Piston Seals, 2 from Bio-Rad
Description:F40 piston seals are supplied as 2 seals with a seal tool to service one F40 pump of a BioLogic DuoFlow workstation....Penguins Altered Diet When Humans Began Hunting Whales and Seals
Adlie penguins living in Antarctica switched from eating fish to krill (shrimp-like marine invertebrate animals) around the time that humans began hunting seals and whales, ancient eggshell fragments reveal. According to Steven Emslie of the University of North Carolina in Wilmington, and William Patterson of the University of Saskatchewan in Saskatoon, it suggests that when human...VERSASEAL™ Plus Single Use Seals
Description:The single-use seal system contains an internal seal to prevent gas leakage when instruments are inserted or withdrawn, without loss of pneumoperitoneum. The 5 mm PLUS system includes an adjusting seal, accommodating instruments ranging from 5 mm - 12 mm as appropriate and is designed to reduce the size of the diameter of the trocar to allow insertion of smaller sized instruments without loss of...
