Terbium-doped garnet single crystals as X-ray-sensitive phosphors

The spectra of luminescence induced by synchrotron radiation in the fundamental absorption range were measured at 10 and 300 K for Czochralski-grown bulk Y₃Al₅O₁₂ single crystals doped with Tb³⁺ ions and for (Tb,La,Gd)₃Ga₅O₁₂ single crystal films grown by liquid phase epitaxy from a PbO-B₂O₃ based supercooled solution melt on Gd₃Ga₅O₁₂ substrates.     

Enteral feeding of patients with surgical diseases of the digestive tract using the Soviet balanced food mixture Inpitan

"Inpitan" is the first Soviet full-value balanced food mixture for tube feeding, produced under industrial conditions. It was used for enteral nutrition of 50 patients with different diseases of the upper gastro-intestinal tract. The mixture contains protein (12%), fat (30%), carbohydrates (58%), all the necessary mineral substances, and water- and fat-soluble vitamins. Depending on the clinical situation the patients received 2000-3200 ml of the mixture/day. The use of "Inpitan" with the energy density of 1 kcal/ml as the only source of nutrition during 7-75 days has demonstrated its high nutritious effectiveness. When the mixture was introduced directly into the small intestine according to the authors' schedule, no dyspeptic symptoms (eructation, nausea, vomiting, abdominal pain, meteorism, diarrhea) were recorded, dipsosis and the sense of starvation disappeared, the body weight increased, biochemical parameters returned to normal, the time of the preoperational preparation was significantly reduced, the post-operational complications were better managed.     

The ВД-12НФП Eddy-Current Flaw Detector and Methods for Processing a Measured Signal Produced by a Flaw

The field of application, the features of operation, and the main performance characteristics of a -12 eddy-current flaw detector are considered. Methods of digital data processing for improving the recognition of flaw-produced signals against the background noise are presented.     

Films based on the phases in the Si-C-N System: Part 1. Synthesis and characterization of bis(trimethylsilyl)ethylamine as a precursor

The characterization of bis(trimethylsilyl)ethylamine was carried out using a combination of IR, UV, ¹H, ¹³C, ²⁹Si, and ¹⁵N NMR spectroscopy, as well as elemental analysis. The spectral characteristics of the compound were determined. The temperature dependence of the saturated vapor pressure was established by tensimetric studies, and the thermodynamic characteristics of vaporization were calculated. Thermodynamic simulation of the chemical vapor deposition was performed and was used as a basis for predicting the composition of the deposited phase complexes depending on the type of reagent and the process conditions.     

Interference microscope-profilometer

The structure and functional capabilities of a digital optical microscope-profilometer capable of operating in two modes, those of micro- and nanomeasurements, are presented. The instrument operation principle is based on measuring the phase function of the wave front of light scattered by the measured surface. Software for the microscope-profilometer and its performance characteristics are considered.
