But it’s really a first step.” In this study, Kerth and his team analyzed hundreds of thousands of erythrocytes from hibernating bats ( Nyctalus noctula ) and non-hibernating bats ( Rousettus ...
NHibernate is a port of the Hibernate object–relational mapping (ORM) tool for the Microsoft .NET platform.
