Vibrational structure of the B-X system of isotopic AgO molecules
(Spectroscopy Letters, 1999)
Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obtained in a low-pressure are in oxygen atmosphere, and recorded with medium dispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system ...
Phase composition and fracture toughness of Si3N4-ZrO2 with CeO2 additions
(Ceramics International, 1999)
Zirconia toughened Si3N4 was prepared with addition of CeO2 by applying hot pressing technique. Phase composition, densification, fracture toughness and hardness were investigated as a function of hot pressing temperature ...
Surface properties of metal ions modified silicas
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 1999)
The surface properties of metal (alkali and alkaline earth) modified silica beads were investigated by the inverse gas chromatography method. Silica beads, obtained from silica sol, were characterized by their specific ...
Thermodynamics of cadmium halide complex formation in acetamide - Calcium nitrate tetrahydrate melt
(Journal of Molecular Liquids, 1999)
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 degrees C. The formation constants ...
The microstructural changes of cobalt powder in consequence of cold pressing process
(Crystal Research and Technology, 1999)
The application of pressure as a technique for obtaining dense and mechanically strengthen materials has been investigated from the structural aspect by the use of X-Ray Powder Diffraction (XRPD) and Scanning Tunneling ...
Germline mutation analysis of BRCA1 and BRCA2 genes in Yugoslav breast/ovarian cancer families
(Oncology Reports, 1999)
The frequency of germline BRCA1 and BRCA2 mutations was tested in Yugoslav breast and breast/ovarian cancer families using combined heteroduplex/single-strand conformation polymorphism analysis for the entire coding region ...
Concentration measurements of Be-7 and Cs-137 in ground level air in the Belgrade city area
(Environment International, 1999)
Concentrations of Be-7 and Cs-137 in ground level air in the city area (Belgrade, central Serbia) were determined in the period from 1991-1996, The average monthly concentrations of Be-7 in ground level air were in the ...
A PC-based radiation monitor
(Instruments and Experimental Techniques, 1999)
A low-cost high-precision system for monitoring the radioactivity level has been developed on the basis of a personal computer using the modern concept of virtual instrumentation. The proposed device has certain advantages ...
Computer study of uranium extraction from phosphoric acid at various organic flow arrangements
(Hungarian Journal of Industrial Chemistry, 1999)
Simulation of the first cycle of the DEPA-TOPO process of uranium recovery from wet-process phosphoric acid with mixer-settler contactors operated in a counter-current (CTC), cross-current (CSC) and an alternative ...
Spectrophotometric and electrochemical study of protolytic equilibria of some oximes-acetylcholinesterase reactivators
(Journal of Pharmaceutical and Biomedical Analysis, 1999)
Newly synthesized oximes, mono and bis imidazole derivatives, which promise to be more effective acetylcholinesterase reactivators than standard antidotes used, were investigated by spectrophotometric and electrochemical ...
