Indirect determination of thallium by differential-pulse polarography
(Elsevier, 1985-06)
The method is based on the separation ofTl(I) as Tl2HPMo12O40, stripping of the molybdate, and measurement of the peak current in differential-pulse polarography of the molybdenum. The calibration graph is linear over the ...
Free-jet spectra and structure of o-, m- and p-dihydroxybenzenes
(Elsevier, 1985-11-15)
Analysis of the free-jet spectra of hydroquinone (para), catechol (ortho) and resorcinol (meta) shows the presence of multiple origins in each molecular spectrum which are interpreted as belonging to separate structural isomers.
Design of a real-time inspection system for NDE of reactor vessels and piping components
(Elsevier, 1985)
Progress in the development of a special-purpose system for use in a real-time in-service inspection system for reactor vessels and piping components is described in this report. An analysis of the synthetic aperture ...
Evidence for two cyclic photophosphorylation reactions concurrent with ferredoxin-catalyzed non-cyclic electron transport
(Elsevier, 1985-06-26)
Addition of ferredoxin to isolated spinach chloroplast thylakoid membranes reconstitutes phosphorylating electron transfer characterized by elevated P/O ratios (1.6). When oxygen is the terminal electron acceptor for reduced ...
Thermodynamics of uranium intermetallic compounds I. Heat capacities of URu3 and URh3 from 5 to 850 K
(Elsevier, 1985-11)
Heat capacities of carefully characterized samples of URu3 and URh3 were measured by adiabatic calorimetry from 5 to 350 K by adiabatic calorimetry and from 300 to 850 K by enthalpy-increment drop calorimetry. Values for ...
Prediction and measurement of initial flocculation rates in quiescent media
(Elsevier, 1985-12)
Initial flocculation rate experiments were carried out with a dilute suspension of bidisperse polystyrene spheres (0.166 and 0.255 [mu]m in radius) under normal gravity conditions and, using a centrifuge, under conditions ...
Fischer-tropsch synthesis on charcoal-supported molybdenum: The effect of preparation conditions and potassium promotion on activity and selectivity
(Elsevier, 1985)
High dispersion and high activity charcoal-supported molybdenum catalysts were prepared using incipient wetness and equilibrium adsorption methods. Activities and selectivities of these catalysts were tested after reducing ...
Comparison of the 5' regions of human and mouse carbonic anhydrase II genes and identification of possible regulatory elements
(Elsevier, 1985-12-18)
The nucleotide sequence of the 5' region of the human carbonic anhydrase II gene has been determined. This sequence begins 643 base pairs upstream from the ATG start site and continues through exon 1, intron 1, exon 2 and ...
Effect of dietary cholesterol on erythrocyte peroxidant stress in vitro and in vivo
(Elsevier, 1985-07-31)
The effect of dietary variation of plasma cholesterol concentrations on the susceptibility of erythrocytes to in vitro and in vivo peroxidant stress was studied in rats. Malonyldialdehyde, produced in vivo (endogenous ...
