This is stored in a character column called COOLING , which may contain the strings ' REGULATED ' if an active closed-loop cooling system is used (either thermoelectric or some other servo-controlled cooling ); 'UNREGULATED' if the tube is cooled in some way, but not regulated ; ' ICE ' if ordinary (water) ice is used as coolant; 'DRYICE' if dry ice (solid carbon dioxide) is ...

... Obviously, the size of the cavern is of the order of the Schwartzman radius. ... Thus, consideration of the inverse effect of pulsar radiation on the properties of accreting plasma makes the ejection possible even when the Schwartzman radius is smaller than the capture radius. ... If the cavern radius , the condition at its boundary can be written as . ... Apart from magnetic dipole radiation, the cavern may also contain relativistic particles (which are also reflected from the cavern boundary). ...

between bottom maps and sonar and hooks that can be trolled at any level - with a sort of airplane plus weights arrangement - and legal limits on net sizes (length and depth), it is now possible to both count salmon more efficiently and also to capture an appropriate percentage while leaving enough escapement for the next generation under ideal circumstances. ocean temp changes and more ruthless foreign fishing in russian zone and escaped farm ...
