The article considers the problem of defining a number of advantages and key moments for ultrasound clearing of parts in Freon-compositions. The designs of ultrasound units, used in the earlier production, are proposed. The comparative identification of cleaning mixtures in regard to their components is conducted. The…
The calculations of the electromagnetic, hydrodynamic and temperature fields crystallized melt with diameter 163 mm. Obtained full picture of the dynamics of crystallization. Calculated speed of crystallization of the different layers of the metal melt.
The progress of inorganic chemistry is syntheses of new triple phosphates Ca 9 CoM(PO 4 ) 7 (M = Li, Na, K) were synthesized by solid state method. Their crystal structures were determined by Rietveld analysis. They are related to tricalcium phosphate and crystallize into trigonal system (space group R3c) with unit-ce…

Paper presented at the 9eme edition des Journees de l'EELS, 23-26 juin 2014, Roscoff (France).
Из горячих источников п-ова Камчатка и о. Кунашир выделены анаэробные гипертермофильные археи родов Thermogladius и Desulfurococcus, способные разлагать - и -кератины. На примере двух из них штаммов 2355k и 3008g показано наличие у этих организмов высокомолекулярных связанных с клеткой эндопептидаз, активных по от…
Elevated mechanical properties up to 2 times in the samples doped with oxygen in the recovery process, which can be explained qualitatively better communication titanium and oxygen, carried out at a chemical level in the recovery process.
Keynote at the 1st International Symposium on Nanoparticles/Nanomaterials and Applications, which took place in Caparica (Portugal) during 20-22th January 2014.
The features of plasma electrolytic oxidation of aluminum alloy AL25 in the alkaline electrolyte with the addition of potassium permanganate are discussed. The influence of the electrolyte nature and electrolysis regimes on the composition, surface morphology and thickness of the oxide coatings are determined. The pos…
The process of designing the construction site should be closely linked to the assessment and analysis of the results. This will allow to achieve the goal. Such an assessment is made on a range of indicators, both quantitative and qualitative, as well as the various stages of the process. Analysis of recent achievemen…
The physiological characteristics of the skin are greatly affected not only by their races, gender, and habit but also by the climate and surrounding environments. This study aims to examine on geographical and racial differences in the characteristics of facial skin type, make-up styles, color preferences, and skin c…
Поиск альтернативных видов топлива для улучшения экологической ситуации, вызванной использованием дизельного топлива, является актуальной научной проблемой. Исследована возможность получения моноалкильных эфиров жирных кислот c использованием липазы из масляных экстрактов водорослей Cladophora sp., Spirogira sp. и Oed…
The necessity of the products manufacture made of titanium and its alloys inUkraineis shown. An integrated barshaped semi-finished welding technology of sintered titanium alloys is developed. Мicrostructural and fractographic investigations and mechanical tests of semi-finished products were conducted. On the basis of…
In the article method of the directed descriptions spherical array calculation is driven. The basis of method is possibility of electromagnetic radiation focusing at forming of multifrequency spatio-temporal signal. For that basic method of calculation correlations are got main expressions for the calculation of the f…
