In automated control systems for technical processes, the conversion of a continuous signal into a digital code and vice versa from a digital code to a continuous (analog) value is widely used. For direct type converters often used the term ADC, the reverse - DAC. The characteristics of the converters often dramatically affect the parameters of the entire automated system. The importance of the correct choice of ADCs and DACs has especially increased recently in connection with the mass introduction of microcontrollers MC. Indeed, in addition to the ADC and DAC, it is necessary to place the processor core in the microcontroller's crystal, I/O interfaces and many other elements necessary for the functioning of the MC. The use of information converters in the construction industry imposes additional requirements on converters: for example, in building monitoring systems, precision ADCs with extremely high accuracy are often required (while performance may be low), in other applications it is necessary to provide the necessary parameters at a high level of industrial interference, etc. This article explores issues related to the rational choice of ADCs and DACs, taking into account current trends in the IT field and the specifics of work in the construction industry. Sigma-Delta converters are noted as the most promising models of direct type converters.

Space Life Support

Life support for first manned spaceflights was based on supplies of consumables. Crew life support systems based on supplies of water and oxygen, in spite of their simplicity, are extremely inefficient in orbital space missions and are unfeasible in deep space missions because of mass and volume constraints. Therefore, there are currently developed and are to be used on space stations the life support systems that are based on chemical and physical regeneration of water and oxygen extracted from human waste. In view of further advances in long-duration orbital stations, and the prospects of establishment of planetary outposts and deep space exploration, the problem of constructing an automated system for controlling a suite of regenerative LSS becomes urgent. The complexity of solving the problem of constructing an efficient control system in this case owes to the existence of a large number of effectiveness criteria. The paper proposes a system of consolidated global efficiency criteria, which allows to break up this problem into a series of sub-problems of optimization in order to solve this problem. The proposed criteria are longevity, cost, comfort. The paper presents a series of specific examples of using the proposed principles with necessary generalizations. Key words: space life support systems, atmosphere revitalization equipment, automated control system, global generalized efficiency criteria, longevity, cost, comfort.

This chapter discusses contractualist theories of justice that, although they rely explicitly on moral assumptions in the traditional understanding of morality, employ rational choice theory for the justification of principles of justice. In particular, the chapter focuses on the dispute between Rawls and Harsanyi about the correct choice of principles of justice in the original position. The chapter shows that there is no winner in the Rawls–Harsanyi dispute and, ultimately, formal methods alone cannot justify moral principles. This finding is significant for the development of the rational decision situation that serves for the derivation of the weak principle of universalization for the domain of pure instrumental morality.

Background. Most of the current models for experimental burns pose difficulties in ensuring consistency and standardization.Aim of Study. We aimed to develop an automated, reproducible technique for experimental burns using steam-based heat transfer.Methods. The system developed for steam exposure was based on a novel, integrated, computer-controlled design. Three groups of rats were exposed to steam for 1, 3, and 7 seconds. The lesions were evaluated after 20 minutes, 48 hours, and 72 hours after burn induction.Results. One-second steam application produced a superficial second-degree burn; three-second application induced deep second-degree burn; and seven-second application led to a third-degree burn.Conclusion. The high level of automation of our integrated, computer-controlled system makes the difference between our system and other models, by ensuring the control of the duration of exposure, temperature, and pressure and eliminating as many potential human generated errors as possible. The automated system can accurately reproduce specific types of burns, according to histological assessment. This model could generate the reproducible data needed in the study of burn pathology and in order to assess new treatments.

The market for design work in civil and industrial construction was one of the first to react to the crisis trends during a pandemic in the economy. Back in 2013, the volume of orders declined, and the peak of the decline was in 2014. The main reason for the difficulties is the reduction in investment programs of civil and industrial enterprises, and developers. The Ukrainian market for design works is distinguished by a high level of competition. A large number of design companies are actively working in this market niche. This fact constantly pushes market participants to take active steps to adjust the competitive strategy, positioning strategy and pricing. The primary signs of a crisis in design are also recognized through price indicators, which personify both the cost of the project or design services, and the results of the project enterprise, taking into account the factors that form the price level. In recent years, the price indicators of the construction industry have been unstable and completely dependent on external market conditions. Price as an economic characteristic is a significant regulator in the project market of Ukraine and abroad. The design market is the backbone of the construction industry with a volume of over UAH 1 billion per year and high added value. The field requires highly qualified staffing and the introduction of modern technologies. Outdated systems of training, certification of specialists and technical regulation hinder the development of the project market in Ukraine. The market is prone to underestimated cost of design work. In 2018, the share of design in the total cost of construction in Ukraine averaged 1.5-2%; in France it was 8-13%, and in Great Britain the level reached 10-17%. There is practically no system of state orders for design. Today our market is characterized by technological backwardness. The work of designers is low-paid, which, accordingly, affects the quality. High-quality architecture is more expensive than low-quality one. In Ukraine, the demand for quality design is just beginning to emerge. In this regard, it is very important to create a competitive environment that will contribute to development. The project market, like the construction industry as a whole, is extremely heterogeneous. Currently, there are thousands of various design bureaus and small workshops in Ukraine, employing no more than ten people, and the number of freelance designers cannot be statistically estimated. Prices for design, as well as the approaches used to provide services, differ dramatically in these organizations. A high price for a service does not necessarily guarantee that the quality of its delivery will be the same. Therefore, first of all, one should imagine what kind of work will be performed and what their essence is. Many investors prefer to design their facilities using the services of European specialists. What are the features and secrets of the Ukrainian project market? Are there really so few good designers in their country, and by what parameters can they still be found? The article examines the features of the functioning of the Ukrainian market for design work and the development of design in a pandemic.

Introduction: The emergence of High Level Aminoglycoside Resistance (Resistant to Gentamycin and Streptomycin) and Vancomycin Resistant Enterococci among Indoor and Intensive Care Unit admitted patient presents a serious challenge for clinicians. Objective: To determine Enterococcal burden in blood and urine specimens and to detect the prevalence of High Level Aminoglycoside Resistance and Vancomycin Resistant Enterococci. Material & Methods: One hundred ten Enterococci were isolated from blood and urine samples and processed according to standard laboratory protocol. Species identication and sensitivity was done using the VITEK 2 automated system (Biomerieux France) with the cards GPID and AST 67 respectively. Results: Out of 110 Enterococci isolates, 36 were from blood and 74 from urine were detected. Different Species isolated were Enterococcal faecium (59%), Enterococcal faecalis (34%), Enterococcal rafnosus (2.7%), Enterococcal gallinarum (1.8%), Enterococcal casseliavus (0.9%) and Enterococcal duran (0.9%).Out of 36 blood isolates, 14 (38%) were found to be both High Level Gentamycin Resistant (HLGR) & High Level Streptomycin Resistant (HLSR), 10 (27%) were only HLGR and 8 (22%) were only HLSR. 20 strain (55%) of Enterococcus species isolated in blood were VRE. All VRE strains were found to be resistant to both aminoglycosides ( HLAR).Among the 74 urinary isolates, 24 (34%) were found to be both HLGR & HLSR, only HLGR was observed in 20 (27%) and HLSR was observed in 11 (14%) isolates. 24 strains (34%) of Enterococcus species were found to be vancomycin resistant in urine. 23 strains out of 24 were resistant to high level of aminoglycosides. Conclusion: The prevalence of HLAR and VRE is very high among Enterococcus specimens from indoor/ intensive care unit patients. Early species identication and antibiotic sensitivity result can help in better clinical outcome.

The aim of the study was to investigate vancomycin and high-level aminoglycoside resistance (HLAR) in <em>Enterococcus</em> species by phenotypic and genotypic methods. A hundred <em>Enterococcus</em> strains were included in the study. Antimicrobial susceptibilities of strains were investigated by automated system, betalactamase production was investigated by nitrocefin disks, vancomycin resistance and HLAR were investigated by gradient diffusion method (GDM) and disk diffusion method, respectively. For detection of vancomycin and high-level gentamicin resistance (HLGR) genes, polymerase chain reaction was used. Teicoplanin linezolid, vancomycin, ampicillin, penicillin are the most susceptible antibiotics and strains were detected not to produce beta lactamase. Vancomycin resistance was detected in ten isolates by automated system and in only five isolates by GDM. Five isolates carrying <em>VanA</em> gene were determined. The ratio of HLGR and high-level streptomycin resistance was found 40 and 63% respectively. <em>aac (6’)-1eaph (2’’)-1a</em> gene was detected in 58% of strains. <em>E. faecium</em> strains were found more resistant to the antibiotics than the other species. Beta lactamase was detected in none of strains. The automated system detected vancomycin resistance in more strains than GDM. Therefore it is concluded that strains, which were detected to be resistant to vancomycin, should be confirmed by GDM. The ratio of <em>VanA</em> gene in strains is consistent with other studies. The HLAR ratio was found in about half of strains. The ratio of<em> aac(6’)-1e-aph(2’’)-1a</em> gene, which is the most reported gene in our country and other countries and one of the HLGR genes investigated in our study, was detected 58%.

This paper aims to review the use of various construction procurement systems and present the development of Relationship-Based Procurement (RBP) Methods currently in use within the Australian construction industry. Therefore, this paper provides the historical development of procurement briefly and then focuses on the adoption of Relationship-Based Procurement (RBP) approaches in the Australian construction industry to investigate the future direction of the collaborative project procurement arrangements. Semi-structured interviews with high-level managers in the Australian state government organizations have been conducted to answer the research question. A discussion has been presented about the potential future tendency of the industry in adopting a RBP. The findings suggest that even though relationship based procurement systems offer significant benefits; they are not popular among the public sector decision makers because of inability to demonstrate Value for Money (VfM) propositions for public projects. Other reasons which may cause a move away from using RBPs in the future include the need for managers to fully engage throughout the project, and the lack of collaborative environment within the construction industry in general.

Results of feasibility tests of application of Cold Crucible Inductive Melting (CCIM) technology to high level waste (HLW) treatment on examples of Savannah River Site, USA, and PA “Mayak”, Russia, HLW, carried out at SIA Radon, and results of design of new perspective bench-scale HLW vitrification facility are presented in this report. Full-scale low level waste (LLW) vitrification plant is under operation at Radon since 2003. Successful Radon experience aroused an interest to this technology from US DOE. Since 2001 Radon performed tests on vitrification of surrogates of various types of HLW stored at US DOE Sites. Process variables were determined and vitrified wastes were characterized in details. Since 2007 Radon was a subcontractor in the project on design and construction of a new CCIM based vitrification facility at PA “Mayak”. From preliminary tests on Mayak HLW surrogates the main technological features of CCIM process were determined and principles of the process control were formulated. Radon performed the design of the cold crucible and automated control system. On the base of analysis of previously and newly obtained data the main requirements to designing of cold crucible melters and auxiliary equipment, intended for actual HLW treatment, were worked out.
