A new efficient synthesis for 2-thiopteridine-4,6,7-triones (6-10, 15) has been found in the condendation of the appropriate 5,6-diaminopyrimidine (1-5, 14) with oxalic acid in DMF.Analogous condensations with dimethyl oxalate led to S-alkylation probably via an intermediate O-methylation of the DMF.8-Methyl-2- thiopteridine-4,6,7-trione kit ethos
Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour.Using biologgers, we tagged 62 post-moult Weddell seals in McMurdo Sound and vicinity between 2010 and 2012.Generalized ad
Uranium dioxied is used as a nuclear fuel.Depending on the temperature and oxygen partial pressure, it is incredibly versatile and can accept a wide variety of stoichiometry.Many methods are used to estimate the non-stoichiometric O/U ratio such as the coulometric harmoni headband titration, gravimetric and voltammetric methods.These methods have s
