Measurements have been carried out on bulk zinc and brass between room temperature and 1.2°K. The susceptibility values of Zn agree with those of other authors. The diamagnetic brass becomes paramagnetic at low temperatures. This paramagnetism does not obey a Curie or Curie-Weiss law. At low temperatures saturation appears.
A quantitative 1H and 11B NMR study of the redistribution equilibria between the NMe2 group and the Cl, SMe,OMe and F substituents on the mono and difunctional boron centers (R2B- and RB<) is reported. The preferential affinity of the amino Buy Chi Hair Straightener
group towards dialkylated boron centers is shown by the examination of the “intersystem” constant sets. A relative affinity scale is proposed.
A patient experienced recurrent postural headache, transient visual obscurations, and papilledema. The patient initially presented with papilledema Replica Ghd Hair Straighteners China
without cerebral venous sinus thrombosis (pseudotumor cerebri, idiopathic intracranial hypertension). One year later she had the similar symptoms and a recurrence of papilledema but now had obvious venous sinus thrombosis.
