The deadline to order seeds is March 1. Seed packages can be picked up on March 19 during the Seedy Saturday seed exchange at Ester’s Hartung Hall. Those interested in participating in the CRANS-MONTANA, Switzerland (AP) — Czech skier Ester Ledecka shrugged off her Olympic disappointment Saturday by winning the first women’s World Cup downhill after the Beijing Games. Ledecka had an attacking run down the Mont Lachaux course in perfect sunny conditions to earn her third career win and second in downhill, more than two years after her maiden triumph in Lake Louise, Alberta.

Their advantages promoted the use of EOs mostly in medium voltage trans- formers (generally below 35 kV)(Bertrand, 2012). Their use in high voltage.

At higher voltage levels (>66 kV), it is not always possible to use a mineral oil designed transformer with an ester fluid, some. with natural ester fluid rather than mineral oil. In addition, the transformer had to demonstrate robust cold start capability. A supplemental.
