Progress in modeling heat capacity versus temperature morphology
(Elsevier, 1986-12-15)
After discussion of other models for representing heat capacities, the volumetric model used in resolution of lanthanide Schottky contributions over the cryogenic range and a more recent single-parameter formula to represent ...
Evidence for a regulatory role of CTP : Choline phosphate cytidylyltransferase in the synthesis of phosphatidylcholine in fetal lung following premature birth
(Elsevier, 1981-07-24)
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices ...
Characteristics of an aminohydrolase distinct from adenosine deaminase in cultured human lymphoblasts
(Elsevier, 1981-04-14)
An inherited deficiency of adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4) is associated with an autosomal recessive form of severe combined immunodeficiency disease. Affected patients exhibit markedly reduced ...
The effects of suspended residual solids on the rheology of coal-derived liquids
(Elsevier, 1982-05)
The rheology of the products of coal liquefaction was investigated using a Weissenberg Rheogoniometer, Model R-16, modified to allow total-normal-force measurements. Solvent extracted oils and asphaltene fractions were ...
An enzymatically inactive variant of human lactate dehydrogenase-LDHBGUA-1 Study of subunit interaction
(Elsevier, 1982-03-18)
The LDHBGUA-1 variant is an electrophoretic variant which is enzymatically inactive. It is only detectable because of its ability to form heterotetramers with A and/or active B subunits and alter the electrophoretic pattern, ...
Regulation by isoproterenol of muscarinic acetylcholine receptor numbers and sensitivity in rat submandibular, but not lacrimal, glands
(Elsevier, 1982-06-16)
Chronic administration of -isoproterenol, a [beta]-adrenergic agonist, to male Sprague-Dawley rats increased submandibular gland weights by 3 to 4-fold. This increase resulted from a combination of hyperplasia and hypertrophy ...
An investigation of Prussian Blue analogues by Mossbauer spectroscopy and magnetic susceptibility
(Elsevier, 1984)
The Mossbauer spectra and magnetic susceptibilities have been obtained for a series of Prussian Blue analogues of general formula MjA[MB(CN)6]k[middle dot]mH2O where MA and MB are transition metal ions, j and k vary with ...
Dissolution kinetics: Catalysis by salts
(Elsevier, 1981-07)
The dissolution of silicate minerals by hydrofluoric acid has been found to be catalyzed by salts such as NH4Cl, NaCl, and LiCl as well as by strong acids. This catalysis is a strong function of pH and is attributed to the ...
A pseudopotential SCF-MO study of Te 4 2+
(John Wiley & Sons, Inc., 1980)
A recently developed ab initio pseudopotential molecular orbital approach was applied to the Te 4 2+ ion, a system outside the practical reach of conventional all-electron treatments. Computations were carried out ...
