Biological Half-life of Bromide in the Rat Depends Primarily on the Magnitude of Sodium Intake

Summary The parallel course of the excretion rates of bromide and sodium ions was demonstrated in adult male and female rats administered simultaneously with potassium 82 Br-bromide and 24 Na-sodium chloride. The animals were exposed to various intakes of sodium ions accompanied with five different anions: Br -, Cl -, HCO 3 -, ClO 4 -, and SCN -. Regardless of the anion accompanying the sodium ion, the excretion rates of 82 Br -and 24 Na + ions were proportional to the magnitude of sodium intake in the animals. Hence, we have proved our hypothesis that the biological half-life of bromide depends on the magnitude of sodium intake rather than on the intake of chloride

The Destruction Mechanism in GCTs

This paper focuses on the causes that lead to the final destruction in standard gate-commutated thyristor (GCT) devices. A new 3-D model approach has been used for simulating the GCT which provides a deep insight into the operation of the GCT in extreme conditions. This allows drawing some conclusions on the complex mechanisms that drive these devices to destruction, previously impossible to explain using 2-D models. © 1963-2012 IEEE
