Set between the events of Half-Life and Half-Life 2, Alyx Vance and her father Eli mount an early resistance to the Combine's brutal occupation of Earth. The loss of the Seven-Hour War is still fresh. In the shadow of a rising Combine fortress known as the Citadel, residents of City 17 learn to live under the rule of their invaders.

143. Half life: 1.17 m 3. E(level): 2- If Th234 decays on a more excited state of the Pa234, like the Pa234 [166.3], this one decays on the Pa234 [73.920U] and from this it decays on the Pa234. The first decay way is right but the second one is not, because from the 79.92 level it should decay directly on U234. Letrozole, sold under the brand name Femara among others, is an aromatase inhibitor which is used in the treatment of hormonally-responsive breast cancer after surgery. It was patented in 1986 and approved for medical use in 1996. Over the years, procedures to determine the half-life of proteins in cultured eukaryotic cells have been well-established.

SE 78. Nearly all naturally occurring protactinium is 231 Pa with a half-life of 32,700 years. It is an alpha emitter and is formed by the decay of uranium-235, whereas the beta radiating protactinium-234 with a half-life of 6.74 hours is produced as a result of uranium-238 decay. Protactinium-234m is a member of the uranium series with a half-life of 1.17 minutes. It was discovered in 1913 by Kazimierz Fajans and Oswald Helmuth Göhring, who named it brevium for its short half-life. About 99.8% of decays of 234 Th produce this isomer instead of the ground state (t 1/2 = 6.70 hours).
