Ports Look Outward

Outward bound.

Peter Collins, who worked as a policy officer and historian for the Royal Society for 32 years, has written an invaluable, eye-opening account of this premier organization for science, from the Tercentenary of 1960 through to the 350th anniversary of 2010. In doing so he fills a considerable gap in the historical literature. The account is meticulously sourced, drawing on Collins’ unparalleled ...

Tsunami currents in ports.

Tsunami-induced currents present an obvious hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 a...

Ports in a Storm

In many parts of the world, shipping-related emissions have already exceeded or are expected to soon exceed those from land-based sources. Shipping emissions can be reduced substantially by using some of the same technologies being applied to land-based sources, including cleaner engines and fuels, exhaust control methods, and operational modifications. Various ports are testing the feasibility...

Transient Outward Current?

To gain insight into the molecular basis of cardiac repolarization, we have expressed K' channels cloned from ventricular myocardium in Xenopus oocytes. A recently identified human cardiac K' channel isoform (human Kvl.4) has properties similar to the 4-aminopyridine-sensitive calcium-insensitive component of the cardiac transient outward current. However, these channels recovered from inactiva...
