The thermodynamics of ammonium scheelites IV. Heat capacity of ammonium metaperiodate NH4IO4 from 8 to 324 K
(Elsevier, 1987-07)
The heat capacity of the scheelite salt ammonium metaperiodate, NH4IO4, was measured from 8 to 324 K using adiabatic calorimetry. The heat capacity against temperature curve shows an excess with a maximum around 200 K as ...
Determination of an empirical energy function for protein conformational analysis by energy embedding
(John Wiley & Sons, Inc., 1987-10)
It is quite easy to propose an empirical potential for conformational analysis such that given crystal structures lie near local minima. What is much more difficult, is to devise a function such that the native structure ...
The thermodynamics of ammonium scheelites V. Heat capacity of deuterated ammonium metaperiodate ND4IO4 from 8 to 329 K
(Elsevier, 1987-10)
The heat capacity of the scheelite salt: deuterated ammonium metaperiodate, ND4IO4, was measured from 8 to 329 K using adiabatic calorimetry. The heat capacity against temperature curve shows a broad maximum with a peak ...
Identification of gastrin molecular variants in gastrinoma syndrome
(Elsevier, 1987-02)
The molecular species of gastrin in the circulation and in tumor extracts were studied in two groups of patients: (1) with benign gastrinoma and (2) with gastrinoma with liver metastases. Radioimmunoassays (RIAs) and ...
Thermodynamics of copper sulfides III. Heat capacities and thermodynamic properties of Cu1.75S, Cu1.80S, and Cu1.85S from 5 to about 700 K
(Elsevier, 1987-12)
The heat capacities of Cu1.75S, Cu1.80S, and Cu1.85S have been measured by adiabatic-shield calorimetry from 5 to about 700 K. The heat-capacity curves show transitions near 312, 337, and 355 K in Cu1.75S and Cu1.80S and ...
The influence of a plane boundary on the thermophoretic force in the knudsen regime
(Elsevier, 1987-05)
The effect of a plane diffusely reflecting wall on the thermophoretic force acting on a particle in the Knudsen regime is investigated. A general expression for the force on a particle in a nonuniform gas is given and then ...
Low-temperature heat capacity and thermodynamic functions of IrO2
(Elsevier, 1987-11)
The heat capacity from 5 to 350 K of IrO2 has been measured by quasi-adiabatic equilibrium calorimetry. The values for the thermodynamic properties at 298.15 K have been calculated as Cp, m(T)/R = 6.687, [Delta]0TSmo/R = ...
Isolation and characterization of an oxygen-evolving Photosystem II reaction center core preparation and a 28 kDa Chl-a-binding protein
(Elsevier, 1987-03-25)
An oxygen-evolving Photosystem II reaction center complex was characterized by using both biophysical and biochemical techniques. A low-temperature EPR study of this preparation has revealed that cytochrome b-559 has been ...
Immobilization and assay of low-molecular-weight phosphomannosyl receptor in multiwell plates
(Elsevier, 1987-10)
A novel sensitive binding assay for quantitation of a low-molecular-weight phosphomannosyl receptor (41-46 K) was devised. The receptor was immobilized by immunochemical means in the wells of polystyrene multiwell plates. ...
[D-Ala2,(F5)Phe4]-dynorphin1-13-NH2 (DAFPHEDYN): A potent analog of dynorphin 1-13
(Elsevier, 1987)
Intracerebroventricular administration of the dynorphin analog, [D-Ala2,(F5)Phe4]-dynorphin1-13-NH2 (DAFPHEDYN) in rats produced diuresis and profound analgesia. Both effects were antagonized by central administration of ...
