In the spectral region from λ7870 to λ8000 of HD 137613, a hydrogen-deficient carbon star, some lines of the 3ν1+2ν3, 4ν3, and ν2+4ν3-ν2 Sequences of HCN were identified without any blending effects. These observational results seem to be in agreement with the theoretical work by Jørgensen.
Volatilization and mass fractionation of boron during evaporation of the hydrofluoric and hydrochloric acid solutions were investigated with varying mannitol/boron ratios. The degree of volatilization and mass fractionation decreases with increasing mannitol/boron mol ratio and the boron volatilization is completely suppressed when the ratio is more than unity. These results indicate that the final stable compound of boron-mannitol complex is an equimolar complex of boron and mannitol. The formation of this complex allows the use of hydrofluoric and hydrochloric acids for the dissolution of silicate rock samples and for separation of boron from the samples adopting anion exchange chromatography in F- form.
Dystrophin, the product of Duchenne muscular dystrophy (DMD) gene, was purified to 70-80% homogeneity from rabbit skeletal muscle myofibrils by hydroxylapatite, wheat germ agglutinin-agarose, and DE 52 column chromatography. Rotary shadowed image of dystrophin molecules was dumpbell-shaped dimer, 100-120nm long. There were frequently linear aggregates of the dumpbell dimer.
