Thermophysics of the lanthanide trihydroxides IV. The heat capacity of Ho(OH)3 from 11 to 350 K. Lattice and Schottky contributions
(Elsevier, 1981-11)
From values of the heat capacity of microcrystalline Ho(OH)3 determined by precise adiabatic calorimetry from 11 to 350 K, the Schottky contribution associated with the Stark splitting of the ground J-manifold (5I8) was ...
Emulsion stability: Determination from turbidity
(Elsevier, 1981-01)
A novel technique for studying the stability of emulsions has been developed. Owing to the fact that emulsion turbidity is a function of particle concentration and size, the stability of emulsions can be determined by ...
Dopamine [beta]-hydroxylation in diabetes and diabetic autonomic neuropathy
(Elsevier, 1981-08)
Dopamine [beta]-hydroxylase (DBH) has been studied in healthy subjects and diabetic patients, some of whom had autonomic neuropathy. DBH was assayed by a recently described in vivo tritium release method (10,11). Dopamine ...
Characterization of five members of the actin gene family in the sea urchin
(Elsevier, 1981-12-28)
Hybridization of an actin cDNA clone (pSA38) to restriction enzyme digests of Strongylocentrotus purpuratus DNA indicates that the sea urchin genome contains at least five different actin genes. A sea urchin genomic clone ...
Excitation temperature, degree of ionization of added iron species, and electron density in an exploding thin film plasma
(Elsevier, 1981)
Time and spacially resolved spectra of a cylindrically symmetric exploding thin film plasma were obtained with a rotating mirror camera and astigmatic imaging. These spectra were decouvolved to obtain relative spectral ...
[beta]-Glucosidase activator protein from bovine spleen ("coglucosidase")
(Elsevier, 1981-04-15)
[beta]-Glucosidase-stimulating proteins ("co-[beta]-glucosidase") have been isolated from bovine spleen by acidification of homogenized spleen, heat denaturation, and chromatography with DEAE-Sephacel, Sephadex G-75, ...
Quantitation of lipids by charring on thin-layer plates and scintillation quenching: Application to ceramide determination
(Elsevier, 1981-04)
A method is described for the quantitative determination of lipids after separation by thin-layer chromatography: the lipid spots are visualized with a charring spray and the darkness of the spots is determined by measuring ...
Teteraene and pentaene leukotrienes: Selective production from murine mastocytomo cells after dietary manipulation
(Elsevier, 1981-10)
A neoplastic mast cell tumor was grown in mice which had been raised since birth on a diet enriched with eicosapentaenoic acid. Intact harvest mastocytoma cells were stimulated with calcium ionophpore A23187 to produce ...
On the origin of light-induced changes in the proton magnetic relaxation rate of chloroplast thylakoid membrane suspensions
(Elsevier, 1981-03)
The spin-lattice relaxation rate of solvent protons in suspensions of chloroplast thylakoid membranes undergoes a large transient depression following illumination in white light. This change appears to require the presence ...
