In enzymology, a beta-ureidopropionase (EC 3.5.1.6) is an enzyme that catalyzes the chemical reaction. N-carbamoyl-beta-alanine + H 2 O beta-alanine + CO 2 + NH 3. Thus, the two substrates of this enzyme are N-carbamoyl-beta-alanine and H 2 O, whereas its 3 products are beta-alanine, CO 2, and NH 3.
The enzyme trehalose-phosphatase (EC 3.1.3.12) catalyzes the reaction . α,α-trehalose 6-phosphate + H 2 O α,α-trehalose + phosphate. This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds.
In enzymology, an alpha,alpha-trehalose-phosphate synthase (UDP-forming) (EC 2.4.1.15) is an enzyme that catalyzes the chemical reaction. UDP-glucose + D-glucose 6-phosphate UDP + alpha,alpha-trehalose 6-phosphate

Protactinium-231 arises naturally from the decay of natural uranium-235, and artificially in nuclear reactors by the reaction 232 Th + n → 231 Th + 2n and the subsequent beta decay of 231 Th. It was once thought to be able to support a nuclear chain reaction, which could in principle be used to build nuclear weapons ; the physicist Walter ...
However, the 231 Pa (with a half-life of 3.27 × 10 4 years) formed via (n,2n) reactions with 232 Th (yielding 231 Th that decays to 231 Pa), while not a transuranic waste, is a major contributor to the long-term radiotoxicity of spent nuclear fuel. While 231 Pa can in principle be converted back to 232
231 Th has 141 neutrons. It is the decay product of uranium-235. It is found in very small amounts on the earth and has a half-life of 25.5 hours. [53] When it decays, it emits a beta ray and forms protactinium-231. It has a decay energy of 0.39 MeV. It has a mass of 231.0363043 u.
The University of Victoria (UVic) is a public research university located in the municipalities of Oak Bay and Saanich, British Columbia, Canada. [ 10 ] [ 11 ] [ 12 ] Established in 1903 as Victoria College , the institution was initially an affiliated college of McGill University until 1915.
