The WFPHA opens a Geneva office

WFPHA: World Federation of Public Health Associations.

The World Federation of Public Health Associations held its 44th Annual Meeting in Geneva on 16 May 2010. In his final speech to the WFPHA General Assembly, immediate Past-President, Dr Paulo Buss, reflected on 2008–2009. He discussed the Federation’s most important challenges and accomplishments during the last 2 years of his presidency: its most difficult challenges included the worldwide fin...

Structure that Opens the Gate and Opens the Door

Sometimes the best way to solve a problem is to look at it from a different perspective. That is certainly the case in ion channel research. Hodgkin and Huxley must have realized that 50 years ago when they looked at membrane currents with a voltage clamp, and Sakmann and Neher realized it 20 years ago when they measured Possible Symmetries of Tetrameric Channel single-channel currents with the...

A-shell stars in the Geneva system

Among the various kinds of A stars having a peculiar spectrum, we find the A-shell stars. Many questions are still open concerning these stars, including their evolutionary status. In the present study we have used data from the Hipparcos catalogue to examine this point. We have found that the majority of A-shell stars are well above the main sequence. No differences could be established betwee...

Testing for tunneling opens

A tunneling-open failure mode is proposed and carefully studied. A circuit with a tunneling open could pass at-speed Boolean tests but fail VLV testing or IDDQ testing. Theoretical calculations as well as Boolean and IDDQ experiments confirm the existence of tunneling opens. The Murphy experimental data show that seven out of nine VLV-only failure circuits can be explained by this failure mode....
