The article discusses the relevance of developing methodological approaches to the beer and soft drinks accelerated aging method in the market. The controlled indicators selection principles, mainly affecting the quality of the finished product, and the basic equation describing the dependence of changes in indicators on the main temperature factor are given. Studies of the influence of various physical factors (temperatures in the range of 50–60 °C, UV-radiation), both individually and jointly, on the physicochemical and organoleptic characteristics of packaged water for various experimental versions did not show statistically significant changes in the normalized parameters of the basic salt and microelement composition investigated water during storage. The optimal mode of accelerated «aging» of packaged water at an elevated temperature (up to 60 °C) and UV-radiation was established. In the case of soft drinks, thermostating was used when changing the temperature regimes (heat 50 ± 2 °C / cold 6 ± 2 °C) at an exposure time of 30 days, which made it possible to observe a decrease in taste and aroma compared with the control, as well as a decrease in sweetness and the appearance of a slight plastic taste for non-carbonated drink. The influence a temperature regime change on brewing products, which cannot be estimated using the existing method due to the high turbidity, is shown.

An increase in the number of removable denture constructions being produced leads to an increase in the number of complications, which, in turn, reduces the timing of the effective use of orthopedic structures. At present, the problem of treating prosthetic stomatitis and their prevention has not been resolved. Considering the current socio-economic situation, orthopedic treatment of the patients with removable dentures will be relevant for some more time.
Microbiological studies of the ability of basic materials to adhere different types of microorganisms onto their surfaces were performed. There were used 7 different types of resins manufactured according to different technologies.
Having performed a series of microbiological studies on the adhesive ability of basic materials, the following results were obtained. The control was glass, the average index of adhesion to which was 0.69±0.02. The greatest adhesive ability to various types of microorganisms was found in acrylic resins based on polymethyl methacrylate, namely auto-polymer resin Protacryl and resin Sinma. Accordingly, the smallest adhesive properties were seen in non-monomer resins, such as Polian, Nylon, Biocryl with adhesion indices of 0.75±0.04, 0.72±0.03, 0.78±0.03, respectively.

Investigation of the physical properties of carbon under high temperatures (experimental studies)
Authors: Savvatimskii A I , Onufriev S V 
Published: October 2019

Abstract

Key experimental studies (mainly pulse heating) aimed at obtaining the physical properties of the most refractory substance — graphite — in the temperature range of 2000–8000 K are discussed. The properties considered are enthalpy, input (Joule) energy, thermal expansion, specific heat, and electrical resistance, as well as their dependence on the level of applied pressure. The results obtained by pulsed current heating and laser pulse heating are compared. An abnormally high specific heat just before the melting point is recorded under fast (during microseconds) heating of graphite. These effects are presumably associated with the appearance of nonequilibrium defects. A connection between these anomalies and the explosive electron emission is noted.

Published: October 2019

Selama ini silica fume dikenal sebagai bahan campuran pembuatan beton karena dapat meningkatkan kuat tekan beton, menurunkan permeabilitas beton dan memiliki ketahanan sulfat yang tinggi. Dalam penelitian ini mencoba mengaplikasikan silica fume pada pembuatan durable cement. Silica fume dijadikan sebagai bahan pozzolan karena didalamnya mengandung silica tinggi yang bersifat reaktif agar dapat meningkatkan ketahanan terhadap sulfat. Bahan pozzolan ini dapat bereaksi dengan Ca(OH)2 pada suhu biasa untuk membentuk senyawa bersifat semen. Pada penelitian ini silica fume divariasikan mulai dari 0; 7,5; 15; 22,5; 30; 37,5%. Durable cement ini akan diuji ketahanan sulfatnya dengan menggunakan metode pengujian kuat tekan. Hasil percobaan menunjukkan terjadinya penururan nilai kuat tekan sampel pada umur 7 dan 28 hari jika dibandingkan dengan blanko. Hal ini disebabkan lambatnya reaksi pozzolan (silica fume). Namun proses peningkatan kuat tekannya akan terus berlanjut hingga setelah umur 360 hari. Jika dibandingkan dengan Standar Nasional Indonesia (15-0302-2004) semen PPC tipe IP-K, hasil sampel durable cement masih memenuhi standar untuk variabel dengan penambahan silica fume antara 7,5% sampai 22,5%.
Silica fume is known as a mixture of concrete manufacturing since it can increase the compressive strength of concrete, decrease the permeability of concrete and have a high resistance to sulfates. In this research, try applying silica fume to make durable cement. Silica fume is converted to pozzolan because it contains highly reactive silica to increase sulfate resistance. This pozzolan material can react with Ca (OH)2 at a room temperature to form a cement compound. In this study, silica fume was varied from 0; 7.5; 15; 22.5; 30; 37.5%. The durable cement will be tested for its resistance to sulfates by using a compression resistance test method. The results showed that the compressive strength of the sample was decreased at 7 and 28 days compared to the blanks. This is due to the slow reaction of pozzolan (silica fume). But the process of increasing the resistance to compression will continue until after 360 days. Compared with Indonesia cement national standard (15-0302-2004) of PPC type IP-K, the durable cement sample still meets the standard for variables with the addition of silica fume between 7.5% and 22.5%.

Background.The European Population Register EUTOS for CML includes data on adult patients (n = 2904) diagnosed with Ph-positive (Ph+) and/or BCR-ABL1-positive (BCR-ABL1+) chronic myeloid leukemia (CML) in 20 European countries during the period from 2008 to December 2012. Russia took part in this study, having contributed 6.8 % of CML patients to the total number of patients in the Register.Aim.To estimate long-term treatment outcomes in patients with newly diagnosed CML in the Russian Federation in comparison with the data obtained for a pan-European population cohort of patients.Patients and methods.The cohort under study consisted of 197 patients from 6 Russia regions, all of whom were diagnosed with a Ph+ / BCR-ABL1 + CML during the period from October, 1, 2009 to December, 31, 2012. The patients’ median age was 50 (18–82) years, with men and women being represented in approximately equal proportions.Results.In the first line, 97 % and 3 % of the patients received Imatinib and 2nd generation tyrosine kinase (TKI) inhibitors, respectively. The response dynamics was as follows: 12 months after the treatment, a complete cytogenetic response and a major molecular response were achieved in 40 % and 20 % of the patients. The overall survival (OS) and progression-free survival rates in patients in Russia following 12, 24 and 30 months were 93 %, 87 % and 84 %, and 92 %, 87 % and 87 %, respectively. In Russia, the study was prolonged. By 80 months of observation, the OS of patients in the chronic CML phase with a low and high risk of the disease progression had been 88 % and 56 %, respectively. In the acceleration phase, the 5-year overall survival rate was 39 %.Conclusion.An analysis of treatment outcomes in CML patients in a population-based non-selected sample indicates an increase in the survival of CML patients. However, problematic aspects of the therapy have been identified, along with a need for intensification of the treatment in patients with an unfavourable CML prognosis.
