Unique field study program Exact today in 2 weeks, there will be a
worldwide study organized upon the behavior of cattle exposed to low frequency magnetic field from power overhead lines. The Ministry of Education, Youth and Sport of the Czech Republic http://web.mvcr.cz/archiv2008/english/index.html <http://web.mvcr.cz/archiv2008/english/index.html> and the university of Duisburg–Essen (http://www.uni-duisburg-essen.de/ <http://www.uni-duisburg-essen.de/> ) have invited specialists in EM worldwide to participate in an cattle observation program. They have asked the EM-community to use their networks to address suitable specialists having access to vector field strength measurement equipment. Due to variations in the earth magnetic field versus time, these observations need to take place at exactly 12:00 GMT. (sorry you guys in the US, you will be late for dinner or worse, but you are better off than the Chinese having to stay up all night). The observation program consist of observing any power overhead exposed cattle field and recording the actual nose-tail orientation in grads towards magnetic north of the cattle at that time. Best mean to do that is using a photo camera at considerable height. At the time of observation an indication of the local field strength should be recorded also for each animal recorded individually. For this value to actually represent the field situation a vector measurement need to be made exactly at the position of each specimen. The organizing committee has decided to standardize the exact location to be at the tail of the animal, to prevent the risks of the cow biting the observer.

Some Australians proved that pigeons home using magnetite particles. They exposed the pigeons in a ceramic enclosure with a special cover of organic material to a temperature above the Curie temperature and showed that they lost all sense of direction. However, they tasted delicious. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better. But that's not the only option.
