Published: November 2021

Introduction. Introduction. Low-profile effective antenna systems (AS) with maintained directional characteristics in a wide sector of scanning angles are required for satellite communication at mobile objects. This article investigates the directional characteristics of a subarray based on a Fabry–Perot cavity and an antenna array with mechanoelectrical beam steering.Aim. To investigate a Fabry–Perot based antenna array with mechanoelectrical beam steering and to estimate its gain and directivity at different scanning angles.Materials and methods. Computer simulations were carried out using the finite element method (FEM), finite difference time domain (FDTD) method and template based post-processing.Results. A subarray based on a Fabry–Perot cavity for an antenna array with mechanoelectrical beam steering was simulated. The efficiency of the subarray comprised at least 65 % in the 11.9…12.5 GHz frequency band. An antenna array based on a Fabry–Perot cavity with mechanoelectrical beam steering was developed and investigated. The calculated characteristics of the developed antenna array agreed well with those obtained experimentally. The gain degradation did not exceed 2.5 dB in the 0…70° scanning angle range. The advantages of using antenna elements based on a Fabry–Perot cavity and developing on their basis mobile satellite antenna systems with wide-angle scanning are noted.Conclusion. The use of a radiator based on a Fabry–Perot cavity and the development on it basis an antenna array with mechanoelectrical beam steering provides an antenna efficiency of no less than 0.5 with a gain degradation of no more than 2.5 dB in the scanning angle range 0…70° from 11.9 to 12.5 GHz.

Published: November 2021

Introduction. X-ray inspection plays a unique role among all nondestructive testing methods for products and materials due to sufficiently high resolution and high penetrability. The present study is designed to consider the key features of microfocus X-ray sources, their areas of application, and main technical characteristics.Aim. The paper aims to systematize information and review modern X-ray radiation sources for the implementation of microfocus radiography.Materials and methods. The main designs of microfocus X-ray tubes (soldered and demountable) were considered relying on the experience of the St Petersburg State Electrotechnical University in developing and operating such equipment, as well as the experience and open-access publications of foreign researchers and developers. Data collected by leading research teams over the last ten years were analyzed.Results. The paper presents design features for each main type of microfocus X-ray tubes – soldered and demountable. All key structural elements are considered: an anode assembly, a cathode assembly, and a focusing system. The influence of anode target material on the X-ray tube radiation spectrum is shown. An original design of a liquid-anode microfocus X-ray tube is described to demonstrate its key features and advantages. In addition, the paper gives an overview of cathodes used in microfocus X-ray tubes (tungsten cathode and lanthanum hexaboride cathode), as well as providing a detailed description of calculations performed for focusing systems. Finally, the designs of modern X-ray tubes are presented.Conclusion. Modern X-ray tubes are high-tech products that allow for high-resolution research of various objects. The main advantage of testing performed with the use of X-ray tubes consists in high resolution (micron and submicron). The X-ray images of test objects used to determine their spatial resolution are given, which clearly illustrate the vast possibilities of this technology. In addition, ways to improve microfocus X-ray tubes are briefly discussed. The considered materials can be useful in selecting a nondestructive testing tool, as well as in developing and creating X-ray systems on the basis of microfocus X-ray tubes.

This study developed a combination of Continuous Stirred Tank Reactor (CSTR) for the acid fermentation and the Anaerobic Baffled Reactor (ABR) post-denitrification through high nitrite injection. Volatile Fatty Acids (VFAs) as a substrate for the post-denitrification process were optimally produced in the acid fermentation process. The aim of this study was to obtain the estimation of biokinetic values to predict the effluent wastewater quality in ABR post-denitrification process under unsteady state. The reactor was operated for HRT 7 days at temperature 25-28 ËšC and pH 6-7,2. The influent and effluent substrate concentration were monitored continuously for 160 days. Post-denitrification biokinetic from the Contois equation resulted in the value of hydrolysis rate (Kh) of 0.077 day-1, the substrate transport rate (k) of 4.364Ã—10-6 Lmg-1day-1, maximum specific growth rate (Î¼max) of 0.559 day-1, half saturation constant (KS) of 0.209 mgL-1, microbial decay coefficient (b) of 0.0145 days-1; yield coefficient (Y) of 0.084 g-VSSg-COD-1. The validation of biokinetic parameters based on statistical analysis showed fairly precise results following the trend of experimental data to determine the substrate concentration in the effluent unit. Therefore, the biokinetic values can be applied in the design of ABR post-denitrification using primary sludge incorporation with high strength nitrate.Keywords:Â Anaerobic baffled reactor, biokinetics, Contois, hydrolysis, post-denitrification.
Xosé Filgueira Valverde e a Fundación Barrié

A Fundación Barrié naceu formalmente o 5 de novembro de 1966, día no que está datada a Escritura Pública dos seus Estatutos. O primeiro testemuño escrito conservado que documenta a relación persoal de Xosé Filgueira Valverde coa entidade procede do 29 de abril de 1968, día no que Joaquín Arias, daquela Secretario da Fundación, lle escribe unha carta para agradecerlle o traballo que realizara nas Comisións Primeira e Segunda da mesma. Este tímido vínculo inicial foi asentando pouco a pouco, converténdose Xosé Filgueira, finalmente, nunha persoa esencial para a Fundación no campo das Humanidades.
Foron moitas e moi diversas as iniciativas promovidas pola Fundación Barrié nas que colaborou Xosé Filgueira Valverde. Tiveron unha especial significación as relacionadas co Instituto Padre Sarmiento de Estudos Galegos e o Museo de Pontevedra. Neste, a imaxe e semellanza do que para ese ámbito de referencia fixera entre 1923 e 1936 o Seminario de Estudos Galegos, puxo en marcha en 1973, consolidándoa en 1979 coa firma dun convenio de cooperación coa Fundación Barrié, a Catalogación Arqueolóxica e Artística de Galicia. A ela vincularíanse proxectos de investigación e publicacións de enorme valor para o coñecemento e difusión do Patrimonio Monumental de Galicia.
A Unity of Experience: The Shared Rhythms of Only Wolves and Lions
Authors: Layton James 
Published: November 2021

‘Only wolves and lions eat alone, you should not eat, not even a snack, on your own’
These words from Epicurus are the stimulus for Unfinished Business’ Only Wolves and Lions, a participatory performance in which the audience share a meal, a conversation, a provocation. Joining others in a shared event, individual natural rhythms were consolidated as tensions inherent in the late capitalist Western world were explored.
Since its commodification, time has become an increasingly scarce resource for most people, as a pertinacious expectation of productivity in both work and leisure activities grows exponentially. Investing time in the shared activities of preparing and eating a meal in Only Wolves and Lions, a sense of solidarity was developed as participants addressed the crisis of a lost sense of community.
This article explores ways in which individual rhythms gradually became a collective, shared rhythm, and forged a unity of experience through participation. Writing from an autoethnographic perspective, I draw on Lefebvre’s rhythmanalysis and Bergson’s notion of pure duration to assert that participation in Only Wolves and Lions resulted in a sense of duration distinct from the homogenous, clock-measured time that regulates economic production as an authoritarian force in late capitalist society.
Only the Envelope: An Artistic Exercise in Data Retention
Authors: Mckenzie Vahri G. 
Published: November 2021

Only the Envelope (OTE) combines research methodologies to investigate the ways we share personal information in the public sphere, and document our practices as scholartists. In a live art installation, a “scientist” invited visitors to be involved in an “experiment”: viewing a film while wearing a wireless eye-tracking device. This surveillance technology generated data about viewing behaviour, but of more interest, the work staged encounters that dramatize the act of looking. Engaging in OTE as performance research led to unanticipated findings and the creation of new audiovisual documents when the eye-tracking device was redeployed as a head-mounted camera to reenact the visitor’s experience. These documents extend the work’s artistic outcomes, but are they “the work” or “records” of the work? OTE engages with the traditional debate in performance studies about the supposed ephemerality of performance by illustrating Schneider’s position that the live is a vehicle for recurrence such that a distinction between record and performance collapses, and that photography can mix theatricality and documentality (2011). OTE refused to keep still to submit to its documentation, just as personal data in the public sphere is endlessly generated, captured and recycled in unstable recursion.

INTERNATIONAL LEGAL FRAMEWORK FOR THE PEACEFUL EXPLORATION OF OUTER SPACE: PROBLEMATIC ASPECTS
Authors: ЕЛИЗАРОВ Михаил Владимирович 
Published: November 2021

This paper examines the efficiency of the international legal framework governing activities of States in outer space in view of the existing gaps within it allowing for space weaponization and the use of force in outer space. Purpose: the paper attempts to answer the following question – is there a clear line between peaceful exploration and militarization of outer space, and is it legally permissible to deploy anti-satellite and anti-missile systems in outer space? Methods: the study employs general scientific methods, legal interpreting and forecasting. Results: the following conclusions have resulted from the study: the 1967 Outer Space Treaty does not cover potentially harmful activities of States in outer space; there is no general agreement on the definition of «space weapon»; the line that's drawn between peaceful space exploration and militarization appears to be blurry; the emphasis in understanding the term «peaceful» has shifted towards the meaning of «non-aggressive»; non-aggressive military uses of space allow for the deployment of defensive weapon systems in space.
