Stripping extraction of positive ions from a cyclotron
(Physical Review Special Topics - Accelerators and Beams, 2001)
In a multipurpose cyclotron, it is convenient to use stripping extraction to extract selected positive ions in addition to the usual extraction by stripping of negative ions. The ions are specified as positive or negative ...
Phase-transformation kinetics in triphasic cordierite gel
(Journal of Materials Research, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Electrodeposition and characterization of Zn-Ni alloys as sublayers for epoxy coating deposition
(Journal of Applied Electrochemistry, 2001)
The chemical composition and phase structure of Zn-Ni alloys obtained by electrodeposition under various conditions were investigated. The influence of the deposition solution and deposition current density on the composition, ...
Detection of transforming growth factor-beta 1 in human plasma - A pilot study on breast cancer patients
(Jugoslovenska Medicinska Biohemija, 2001)
There has been much controversy concerning the detection of plasma TGF-beta (1) levels in breast cancer patients. The present study provides preliminary evidence on underestimated plasma TGF-beta (1) levels due to ex vivo ...
Thermodynamics of cadmium halide complex formation in acetamide-calcium nitrate tetrahydrate melt
(Magyar Kemiai Folyoirat, 2001)
The complex formation between cadmium(II) ions and chloride and bromide ions in the melt of 0.8CH(3)CONH(2)-0.2Ca(NO3)(2). 4H(2)O has been studied at six temperatures between 30 and 80 degreesC. The formation constants of ...
Kinetics of thyroxine (T-4) and triiodothyronine (T-3) transport in the isolated rat heart
(Experimental Physiology, 2001)
The dynamics and kinetics of thyroid hormone transport in the isolated rat heart were examined using the modified unidirectional paired tracer dilution method. The uptake of I-125-thyroxine (I-115-T-4) and I-125-triiodothyronine ...
Glucocorticoid receptors in lymphocytes and stability of kidney graft function
(Clinical and Experimental Medicine, 2001)
The glucocorticoid receptors in lymphocytes of patients treated with glucocorticoids after kidney transplantation have been studied in order to determine whether abnormalities in corticosteroid binding and trans-activation ...
Ceramics in the Si3N4-ZrO2-CeO2 system: Phase composition changes and properties
(Zeitschrift fur Metallkunde, 2001)
Silicon nitride-based compositions containing zirconia and ceria additives were prepared by hot pressing in argon atmosphere. The compositions studied can be divided into two groups: (a) with a constant total amount of ...
Step-heating method of measuring thermal diffusivity using parameter estimation
(High Temperatures: High Pressures, 2001)
A variant of the monotonic heating method has been developed for measuring the thermal diffusivity of different types of solid materials, by step-heating with small temperature increments. In analysing the experimental ...
Dosimetric characteristics of tissue equivalent thermoluminescent solid TL detectors based on lithium borate
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2001)
This paper presents the main dosimetric characteristics of newly prepared, complete tissue-equivalent thermoluminescent dosimeters Li2B4O7:Cu,In, and Li2B4O7:Cu, in the form of sintered pellets. The dosimetric characteristics ...
