Abstract
Improving the technical capabilities of manufacturing processes and creating new parts that surpass existing quality benchmarks is a need of modern engineering. Polymer Composite Materials (PCM) are commonly used in the manufacturing of advanced aerospace components. The aim of this work is to study the process of Electrical Discharge Machining (EDM) of PCM VKU-29. To study the process performance, three different types of Electrode Tools (ET) of different materials were used. EDM was performed on three modes viz. maximum, medium, and minimum. The influence of process parameters and the electrode type on the formation of spark gap was investigated. The visual and the microscopic inspection revealed the absence of hairiness and traces of fiber rupture in case of composite ET. Thus, it can be concluded that the combination of smallest value of spark gap and the composite ET leads to the best quality of surface amongst all the other combinations. Moreover, while processing the PCM VKU-29 using composite ET, it is advisable to maintain a spark gap of 0.14 mm for the best results.

Authors: Biryukov V P , Petrovsky V N , Panov D V , Ushakov D V 
Published: February 2020

Abstract
The paper presents the results of metallographic and tribological studies of laser hardening zones of steel samples. A full factorial experiment on laser hardening with a change in the distance from the focal plane, radiation power and processing speed was carried out. The regularities of changes in the depth and width of the quenching zones are obtained from the regression equations. With low-frequency transverse scanning of the laser beam up to 100 Hz, the hardening zones with a width of 20 mm and a depth of 1.4-2.0 mm in one pass were obtained. The wear resistance of the hardened zones is 3.68 times higher than the base material.

Published: February 2020

Abstract
Influence of the gap between the welded edges when sealing the case of electronic devices on the magnitude of the electron emission sensor signal in the process of electron beam welding (EBW) is studied. The impact of electron beam current variation at a constant value of the focusing system current on the penetration depth with the increasing gap between the welded edges is determined. The dependence of the length of the weld at different electron beam currents on samples with an increasing gap between the welded edges is studied. The possibility of controlling the process of electron beam welding by electronic emission from the weld pool is presented. A sensor for electronic emission registration is proposed, which includes an electron collector and an electron current data record system as a part of the EBW installation. The efficiency of the electronic emission sensor directly in the process of sealing under precision welding modes is shown.

Published: February 2020

Abstract
The share of application of laser processing of materials in technological processes of mechanical engineering has increased over the past few years. In this regard, there is a need for reliable control of the technological parameters of the laser welding process. In deep penetration laser welding, part of the beam power is absorbed by the plasma cloud. As a result, a significant decrease in the penetration depth is observed. Using amplitude-time pulse of current in the plasma in the zone of impact of the laser beam on the metal is one of the directions of the work necessary for the control of the processes in the melting channel. The study of the processes of secondary emission in the plasma in the zone of impact of the laser beam on the metal allowed carrying out numerical simulation of the processes during laser welding. The models took into account the dependence on the focusing of the laser beam and other technological parameters of laser welding. The registration of the secondary emission current was also carried out in order to control the geometric parameters of penetration during laser welding. This technique can be used to build methods for the operational control of the welding process.

Abstract
In order to improve the organization and performance of equipment maintenance, innovative proposals were developed and implemented. The explanations were taken into account when determining the methods for evaluating the maintenance performed for the joint approval of a unified methodology of applying the concept of a standard hour. The planning of performing equipment maintenance by day during the whole month was revised, which, in turn, allowed minimizing significant fluctuations in the scope of work and eliminating peak loads. The works on the maintenance of the mechanical and energy components of a single assembly were revised and combined as much as possible, which ensured the more efficient use of working time. Work has been organized on updating the composition of the operations to be performed, since the scope of maintenance work in the assignment forms is not always representative of the complex of necessary operations. Preventive work with subordinate personnel is organized in the field of improving the industrial standards in the workplace.

The application of relational interactive logic in control operation problems by the example of monitoring the server equipment of transport systems
Authors: Zakharov D V , Kuzmin O V 
Published: February 2020

Abstract
The article demonstrates the use of relational interactive logic in solving the problem of monitoring the server equipment of the transport control system. An example of such a problem is the problem of analyzing log records of monitoring server hardware. The server is considered as a special case of the physical control system. The conditions for the correctness of the current state of the equipment are defined in the form of systems of logical equations and inequalities. Solving a system of logical equations by executing a SQL query on a set of tables describing the elementary control systems in the server allows us to judge the deviation of the hardware parameters of the equipment. Recording the correctness conditions in the form of systems of logical equations provides the ability to take into account both the peculiarities of the functioning of the server hardware and some external context within which the server operates. The considered solution demonstrates the applicability of relational interactive logic in solving the problem of controlling individual classes of control systems within the scope of the system analysis discipline.

Published: February 2020

AbstractThe CRISPR/Cas system has recently emerged as a powerful tool to engineer the genome of an organism. The system is adopted from bacteria where it confers immunity against invading foreign DNA. This work reports the first successful use of the CRISPR/Cas system in Caenorhabditis briggsae (a cousin of the well-known nematode C. elegans), to generate mutations via non-homologous end joining. We recovered deletion alleles of several conserved genes by microinjecting plasmids that express Cas9 endonuclease and an engineered CRISPR RNA corresponding to the DNA sequence to be cleaved. Evidence for somatic mutations and off-target mutations are also reported. Our approach allows for the generation of loss-of-function mutations in C. briggsae genes thereby facilitating a comparative study of gene function.

Abstract

Background
Cranial radiotherapy may damage the cerebral vasculature. The aim of this study was to understand the prevalence and risk factors of cerebrovascular disease (CVD) and white matter hyperintensities (WMHs) in childhood brain tumors (CBT) survivors treated with radiotherapy.

Methods
Seventy CBT survivors who received radiotherapy were enrolled in a cross-sectional study at a median 20 years after radiotherapy cessation. The prevalence of and risk factors for CVD were investigated using MRI, MRA, and laboratory testing. Tumors, their treatment, and stroke-related data were retrieved from patients’ files.

Results
Forty-four individuals (63%) had CVD at a median age of 27 years (range, 16-43 years). The prevalence rates at 20 years for CVD, small-vessel disease, and large-vessel disease were 52%, 38%, and 16%, respectively. Ischemic infarcts were diagnosed in 6 survivors, and cerebral hemorrhage in 2. Lacunar infarcts were present in 7, periventricular or deep WMHs in 34 (49%), and mineralizing microangiopathy in 21 (30%) survivors. Multiple pathologies were detected in 44% of the participants, and most lesions were located in a high-dose radiation area. Higher blood pressure was associated with CVD and a presence of WMHs. Higher cholesterol levels increased the risk of ischemic infarcts and WMHs, and lower levels of high-density lipoprotein and higher waist circumference increased the risk of lacunar infarcts.

Conclusions
Treating CBTs with radiotherapy increases the risk of early CVD and WMHs in young adult survivors. These results suggest an urgent need for investigating CVD prevention in CBT patients.
Appeals to Authority in Political Rhetoric: Machiavelli in the Italian Parliament 1945–1994
Authors: Casiraghi Matteo Cesare Mario , Testini Francesco 
Published: February 2020

AbstractScholarship in rhetorical political analysis and parliamentary studies devoted little attention to study how politicians employ intellectuals’ authority and theories in their discourses. We offer methodological directions to navigate this territory, combining quantitative and qualitative analyses to investigate the employment of Machiavelli’s figure in the Italian Parliament. We show that Machiavelli is regarded as a contested authority and that appeals to his arguments can perform different rhetorical functions, which are countered with different rhetorical tactics. In particular, we show that the right appropriates the realist Machiavelli, especially in foreign policy, both as a national symbol and as a legitimate source of insights on political affairs, while the left and the centre resist these claims with alternative rhetorical tactics. Finally, we provide an original dataset and a new theoretical framework for future explorations of intellectuals and other authoritative figures’ rhetorical influence on politics.
