The Effects of Steel Core Imperfection, Gap Size and Friction Coefficient on the Behavior of All-Steel Buckling Restrained Braces
Authors: ÖZKILIÇ Yasin Onuralp
Published: July 2021

Buckling restrained braces (BRBs) which are generally composed of a steel core and a encasing(buckling restrainers) are utilized to resist lateral forces in high seismic regions since BRBs exhibit high energy dissipation capacity, ductility and stiffness. The steel core carries both compressive and tensile forces. During the compression, the core starts buckling and the encasing tries to prevent this buckling. However, due to the unbonding layer/gap between the encasing and steel core, the steel core eventually buckles and contacts with the encasing. Buckling phenomenon is also associated with the initial imperfection and gap size. In this study, the effects of the initial imperfectionof steel core, gap size (1-5 mm)and friction coefficient (0.01-0.5)between the encasing and steel core on the behavior of BRBs are investigated. Pursuant to this goal, numerical analyses using a finite element tool ABAQUS were conducted. A total of 19 numerical models were developed and monotonically loaded. Initial imperfection was implemented to the models using buckling mode shapes.The results revealed that increasing gap size leads to a reduction in load-carrying capacity. It is recommended to keep gap sizes between 1 and 2 mm. On the other hand, initial imperfection does not significantly affect load-carrying capacity and global behavior. However, it was also observed that the fluctuations in load increase as the amplitude of the mode shape and gap size increase. Moreover, the friction coefficient should be kept between 0.01 and 0.05; otherwise, undesired behaviors can be observed.

Authors: ÖZTÜRK Arzu
Published: July 2021

Günlük hayatta tüketilen pek çok gıda, kozmetik ve tekstil ürünü ile yapım ve üretim aşamalarında kullanılan binlerce kimyasal maddeye maruz kalınmaktadır. Bu kimyasal maddelerin çoğunluğu sağlık açısından yeterince araştırılmış ve etkileri ortaya konmuş değildir. Üreticilerin yaklaşımı “zararlı olduğu kanıtlanmadıkça kullanımı uygundur” görüşüdür ki, bu oldukça risk teşkil eden bir yaklaşımdır. İşlem gören bir üründekullanılan kimyasal maddeler, eser miktarlarda bulundukları için toksik etki göstermeyebilir. Ancak paketli ve işlenmiş gıda ürünleri, kozmetikler, giysiler gibi pek çok yoldan bu kimyasal maddelere maruz kalındığındavücuda alınan miktar artmakta ve toksik etki görülebilmektedir. Gıda üretim aşamalarında kullanılan pestisitler, hormonlar ve gübreler, işlenmiş gıdalarda yer alan boyalar, akrilamid, nitrozaminler, fitalatlar ve şeker olarak sunulan aspartam, TiO2, kozmetik ürünlerde ve giysilerin üretiminde de karşımıza çıkmaktadır. Bugün yaygın görülen alerji, otoümmin hastalıklar, kanser gibi pek çok hastalık artık bu kimyasallar ile ilişkilendirilmektedir. Bu çalışma ile gıda, kozmetik ve tekstil ürünlerinde kullanılan zararlı kimyasalların insan sağlığına etkileri değerlendirilmiştir. Bu sayede literatürde tek tek ele alınan zararlı kimyasalların etkileri holistik bir yaklaşımla ele alınmıştır.

Authors: ADIGÜZEL Koray , KRASNOKUTSKA Nataliia
Published: July 2021

Trust is the most important key element in the history of humanity and its success. We see and witness an emerging and exciting technology called Blockchain, eliminating losses caused by anti-trust and relieves pain in our social-build environment. Although the atmosphere in business, management, and society today has been heavily altered and involved, trust stays the same. This requirement leads companies in various industries to use new techniques to ensure their customer's business is in safe hands. Unfortunately, most of the current research is heavily based on the Bitcoin currency rather than its underlying technology, which focuses on revealing and improving Blockchain's limitations from managerial value perspectives. Many of the proposed solutions lack a concrete evaluation of their effectiveness. Many other Blockchain scalability related challenges, including throughput and latency, have been left unstudied. In this study, enabling functions is studied, and Blockchain's contribution to organisations' management is discussed. Besides, applicability in today's economic environment in various industries is studied. It is understood that after the development of technologies that eliminate centralised structures such as Blockchain, the business world is keen to adapt to this change. In this context, it is concluded that including new technologies such as Blockchain increased trust in various industries, and in the majority of the studies, Blockhain considered being an element to reduce costs and create a more transparent environment. It can be said that this technology contributes to the development and better understanding of the application area of the industries mentioned in the study.

Radical Intangibles: Materializing the Ephemeral
Authors: Kenderdine Sarah , Hibberd Lily , Shaw Jeffrey
Published: July 2021

New materialism considers that the world and its histories are produced by a range of material forces that extend from the physical and the biological to the psychological, social and cultural. In recognizing that heritage is not held in objects alone, new materialism discourses echo definitions of intangible cultural heritage (ICH) enshrined in the 2003 UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage. While museums understand the weight of responsibility when engaging with communities of practice, many still restrict the representation of archived ICH material to oral histories, object biographies, video and audio recordings of songs and performing arts. The technical complexities of archiving the ‘live’ perpetuate nineteenth-century museum display conventions, such as fixed-point perspectives and linear approaches to representation. To address this gap, we introduce ‘computational museology’, which brings a systems thinking approach to 'whole of environment' encoding. Such a framework unites, for instance, artificial intelligence with data curation, and ontology with visualization, as well as embodied participation through immersive and interactive interfaces. The implications of such a framework has yet to be fully theorized but it is evident that a new paradigm of materiality comprising ‘radical intangibles’ is taking shape in museums, which signals a break with both Western historiographic orthodoxies and hypothetical paradigms of tangible and intangible heritage. This article foregrounds the emergence of radical intangibles as crucial new digital materialities that are transforming reenacted and embodied practices, which we demonstrate in the discussion of two longitudinal curatorial projects based in China and Hong Kong: the first, 'Hong Kong Martial Arts Living Archive' (HKMALA) in collaboration with the International Goushou Association in Hong Kong, and the second, ‘Remaking Confucian Rites’ (RCR), undertaken in conjunction with Tsinghua University in Beijing. Both of these projects are significant for having taken up ‘technologies of corporeality’ – digital paradigms at the forefront of computer graphics, spatial and temporal modelling, and virtual reality. The powerful tools being developed across the two instances have begun to revolutionize ICH as a practice, a mode of transmission, and an object of study.
Theorizing Born Digital Objects: Museums and Contemporary Materialities
Authors: Zuanni Chiara
Published: July 2021

This paper explores the characteristics of born digital objects and how their materiality is framed and transformed in the musealization process. It draws on vibrant materialism and web archiving, framing born digital objects as assemblages and proposing a distinction between these and reborn digital objects, i.e. their collected counterparts. The paper relates this new framing of digital objects to established museological frameworks, such as analyses of the musealization process through the lenses of semiotics and research on authenticity in relation to digital reproductions, in order to unpick the ontological and epistemological transformation this contemporary form of heritage undergoes in entering the museum.
Exploration of Betrayal in Exploited Spaces: A Bakhtinian Study of The Shadow of the Crescent Moon
Authors: Ali Maryam Amjad , Dodhy Shamaila
Published: July 2021

In post 9/11 literature, the wave of terrorism and its penetration into third world countries have been a serious concern. Since then, Pakistani literature has encapsulated the impact of war on terror in multi-faceted ways – investigating its implications on social, political and cultural levels. This article strives to focus on how betrayal seeps into the exploited spaces of the tribal areas. Bakhtinian studies assess the concept of betrayal from multiple perspectives, considering the applicability of the terms in unveiling the betrayal in relationships and state level as well. By the application of the concepts of chronotope and polyphony, the enforcement and discretion of being betrayed or by betraying have been analysed via considering the aftermaths of imposed war in terms of social-political aspects. The work has also focused on the penetration of betrayal in fictional tribal areas, by the youngsters of a native town who associated themselves with violent groups, spreading anarchy and disorder. The transgression from the order of the normal life due to encounter with grotesque reality has been unveiled in the study. With fear of violence, hope also germinates in the disordered world. It elucidates the multidimensional view of betrayal due to the disparities faced by the people of the tribal area.

Authors: Mohammed K Faizan , Courtney McCracken , Kenneth Lieberman , Traci Leong , Mark R Benfield
Published: July 2021

Objective: We set up a U.S. registry to examine prescription patterns and patient outcomes of repository corticotropin injection (Acthar® Gel) for childhood nephrotic syndrome. Methods: 18 participating U.S. pediatric centers performed retrospective review and prospective observation of patients < 21 years old with nephrotic syndrome treated with Acthar Gel. We captured baseline characteristics, drug regimen and duration, and disease response following treatment. Results: 46 patients, enrolled from 2015 to 2020 were included. 27 (58.7%) were male. 18 patients (39.1%) had a diagnosis of minimal change followed by focal segmental glomerulosclerosis in 16 patients (34.7%). Median age at start of treatment was 12.5 years (IQR 8.5-17.4) compared to 5.3 years at diagnosis (IQR 2.7-10.5 years). 52% were resistant to corticosteroids. The most common Acthar Gel regimen was 80IU twice a week with a median duration of 199 days (IQR 88-365). Among 37 patients with active disease, 18 (49%) were able to achieve partial or complete remission, though all patients that had a positive response were on other immunosuppressants concomitantly. Conclusion: We report the findings of the largest registry cohort of pediatric patients in the U.S. treated with Acthar Gel for clinically challenging cases of nephrotic syndrome. Acthar Gel was successful in inducing remission in approximately half of the patients with active disease at time of treatment. No predictors of response with respect to demographic data, age at start of Acthar Gel therapy, etiology of nephrotic syndrome, presence or absence of comorbidities, or steroid responsiveness was noted.

In a treatment facility in Nigeria community meeting has been an effective strategy in substance abuse management for identifying and addressing motivation in the treatment, insight and judgment, self-esteem, psychotic symptoms, readiness for treatment etc. The components of community meeting significantly facilitate effective transition in stages of change. This research utilised information from various meetings, individual interviews and Focus Group Discussion. The study also obtained information about substance use from files of 211 participants previously admitted from 2014 – 2020, descriptive statistics using SPSS version 20 was utilized in the analysis. The analysis show that male were predominant at 91.9% with a mean of 1.08, 24.6% primary substance of abuse is alcohol and the most common substance abused at 29%. Clients admitted with psychotic symptoms were 47.9% and 29% common problematic substance is cannabis and 65% of them are within the ages of 21-30 years, while 45% of them have used other psychoactive substances like opioids and cocaine. The qualitative study reveals that all the components of community meeting significantly contributed positively in the management of clients. Consequently, community meeting gives people experiencing addiction the opportunity to self-examine, express, and adapt to techniques of living a substance free life effectively. This gathering allows all categories of clients interact freely and respectfully given way to teaching, learning and mentoring. The researchers therefore, suggest that though substance abuse problems may not vary, however, the approach to addressing this problem should be tailored in a ways that reflects the people and their culture.

Modification of the genetic algorithm for comprehensive topological optimization of the synchronous motors rotor
Authors: Petrov T. I.
Published: July 2021

Permanent magnet synchronous motors (PMSM) are widely used in various fields of application of electric drives of industrial enterprises. For each application of the electric drive, it is necessary to accept technical requirements, such as the maximum torque of the electric motor and the fulfillment of the required conditions for the strength characteristics of the rotor and stator.

PMSM has a number of advantages over other types of engines. Asynchronous motors have developed resource rational energy efficiency, while synchronous motors are more energy efficient without modifications. PMSM have smaller weight and size parameters, which allows them to be used in a wider field of application, for example, in household appliances, robots and many other drives.

TARGET. The aim is to develop a methodology for topological complex optimization of the engine design, based on a genetic algorithm.

METHODS. The genetic algorithm is more accurate than traditional analytical methods, the method used in the analysis of AC machines, takes less time than the usual trial and error design procedure based on the finite element method. The main optimization criterion is an increase in torque while maintaining the mass of the most expensive material (permanent magnets). This feature is important for the manufacture of a designed engine in production.

RESULTS. A program has been written in Python, which made it possible to carry out a comprehensive topological optimization for the engine under consideration.

CONCLUSION. Topological optimization based on the method of modifying the rotor design using a genetic algorithm with the additions necessary for correct operation with synchronous motors is presented.

Published: July 2021

THE PURPOSE. The main purpose of the work is a comprehensive study of external influences that affect the operational reliability of low-voltage asynchronous motors. Attention is focused on the evaluation of the operational reliability of electric motors, the systematization of their operating conditions, with the simultaneous impact of a group of operational factors. Among these factors that are subject to detailed analysis, we will highlight the following: the asymmetry of the stress and its duration, loading of the motor, the temperature of the environment. In this regard, it becomes obvious that the task of improving the operational reliability of low-voltage asynchronous electric motors depends on a qualitative study of the quantitative values of external influencing factors in various operating modes of electric motors. METHODS. The tool for implementing this task is a visual and effective simulation tool Simulink interactive programming environment Matlab. RESULTS. The research was performed on an asynchronous electric motor with a short-circuited rotor AIR160S8 with PH = 7,5 kW, rated speed n = 1500 rpm. The physical processes of the electric motor under study were modeled by changing the following parameters: the coefficient of stress asymmetry in the reverse sequence (K2U), the load on the motor shaft (Kz), the ambient temperature (tocr), and the duration of stress asymmetry in the reverse sequence (T). Based on the obtained simulation results, groups of planes of the studied quantities are constructed. CONCLUSION. A set of studies performed using the Matlab software package allowed us to estimate the limits of acceptable values of external factors and identify the area of acceptable operation of asynchronous motors. The analysis and discussion of the research results were carried out, and measures were proposed to improve the operational reliability of asynchronous electric motors.

Objective We aimed to determine the overall profile of patients in a psycho-oncology clinic and the differences in their characteristics according to the cancer site.Methods The charts of 740 patients aged under 81 years were reviewed. The data from 586 completed questionnaires were subjected to multiple comparison analyses using one-way analysis of variance to examine the demographic and clinical differences according to the cancer site.Results Most (n=532, 71.9%) patients were referred. Most new patients (n=426, 96.6%) received a psychiatric diagnosis; the most common diagnosis was depressive disorder (n=234, 31.6%). Likewise, depressive disorder accounted for the majority of diagnoses in all groups except for the digestive system cancer group in which sleep-wake disorder was the most prevalent. The female genital cancer group showed a higher level of anxiety symptoms than other groups, except for breast and haematolymphoid cancer groups, and psychological distress than all other groups.Conclusion There appear to be delays in the referral of cancer patients seeking psychiatric help to a psycho-oncology clinic. Along with tailoring approaches by cancer site, thorough evaluation and appropriate management of sleep-wake and anxiety symptoms are important for digestive system and female genital cancer patients, respectively.

A decisão da construção de uma cúpula de aparência metálica com estrutura em ferro, na Halle au Blé parisiense, nos primórdios do século XIX, foi uma opção muito corajosa e que em muito ajudou a apontar um caminho promissor para a História da Engenharia e da Arquitetura.1 Durante muito tempo, na edificação, a cobertura de largos vãos foi um tema candente mas que encontrava sérias condicionantes derivado a limitações tecnológicas e construtivas. Sem dúvida que as profundas alterações ocorridas durante a Revolução Industrial foram uma questão decisiva para a consagração do uso mais regular do ferro na construção de pontes ou de edifícios. Como fatores determinantes terão contribuído alguns aspetos de índole económica, mas certamente que o desenvolvimento dos meios de transportes ou a possibilidade de fabricação em série foram questões muito relevantes para que a indústria de produção e de transformação do ferro ganhasse um forte incremento da sua competitividade.

Published: July 2021

This article discusses an aspect of the most pressing problem of 2020, that of the spread of infectious diseases. The work considers a railway compartment coach as a particular object of spread of infectious diseases. The objective is to describe spread of the epidemic in a railway coach using a stochastic model. The model of the coach is represented as a network. The processes occurring on the network are considered to be Markov processes. In this paper, two methods of stochastic modelling are applied: modelling based on Kolmogorov equations and Gillespie algorithm. Kolmogorov equations are used to test applicability of Gillespie algorithm, which, in turn, is used to simulate the model of the coach. The obtained data were analysed, and based on that analysis it is possible to make a conclusion about applicability of the model to the case of a typical passenger train.
Influence of the Dista nce of Transportation of Goods on Operating Costs of a Motor Transport Enterprise

Published: July 2021

The object of research is the transportation process. The subject of research is dependence of influence of the distance of transportation of goods on the cost of transportation of goods. Since no studied literary sources have revealed reliable dependences of influence of the distance of transportation on the cost of transportation of goods in specific conditions for a single enterprise, the research task considered in the article seems to be relevant.

The objective of this article is so to study the impact of distance of transportation of construction goods by dump trucks of Volgograd motor transport enterprise on operating costs. The solution to the problem is considered at the example of transportation of bulk cargo by MAN and Mercedes-Benz dump trucks with equal mileage. Several empirical research methods were used: observation (by means of purposeful perception of an object determined by the task of activity), comparison (by establishing similarity and difference between objects and phenomena of reality), measurement (by means of actions performed using measuring instruments to find the numerical value of the measured quantity in the adopted measurement units). To calculate the cost of transportation, the methodology for determining costs for transporting goods by road transport is used. To obtain experimental data, an analysis of the work of fleet of a motor transport enterprise is carried out using waybills with confirmed data. The process of obtaining actual data is carried out by means of calculations according to the given formulas. The research tool is calculation of the cost of transportation of goods according to the data obtained as a result of activities of the enterprise.

Regression dependences of influence of the distance of transportation of goods on the cost of operation of dump trucks with different carrying capacity were obtained to determine the type of the regression equation, construct estimates of unknown parameters included in the regression equation, and test statistical hypotheses about regression. The verification of the adequacy of obtained models was performed by calculating the correlation coefficient to establish the presence of a connection between random variables.
Foreign Approac hes to the Audit of Transport System Efficiency at the Regional Level
Authors: Soldatenko I. A.
Published: July 2021

The article is devoted to consideration of foreign instruments for performance audit in the transport sector and to assessment of possibility of applying the methods and procedures of performance audit by Russian regional control and accounting bodies. The objective of the study is to comprehensively analyse the international experience of regulation and organisation of performance audit in the transport sector based on the practices of the Auditor General of Scotland (Great Britain) and the Auditor General of Manitoba (Canada).

Considering the traditionally high share of regional budget expenditures spent on development of the transport system, it is noted that assessment of the economy, productivity and efficiency of the use of public resources is important not only for regional authorities, but also for the population and business entities.

Based on the analysis of the best practices of regional government audit bodies of Great Britain and Canada in terms of performance audits in the transport sector, advanced methods and audit procedures were recorded that can be applied by Russian regional control and accounting bodies. In particular, the specifics and accuracy of recommendations to the executive authorities presented in the audit report; procedure of assessing correctness of tender procedures and effectiveness of contract execution as part of the performance audit; wide use of external experts during inspections and other features have been noted.
Indicator for Assessing Availability of Rolling Stock for Public Urban Passenger Transport

Published: July 2021

The objective of the article is to develop and to substantiate adequacy of the proposed indicator for assessing availability of rolling stock for urban mass transit or urban passenger transport (UPT). As such an indicator, it is recommended to use a calculated indicator: a conventional one-hundred-seat vehicle. The currently used indicators characterising provision of UPT with vehicles, consider only the physical number of the latter. This does not provide an assessment of carrying capacity of UPT, considering the existing operating conditions (real operating speeds on the routes of UPT, the existing level of the coefficient of the fleet being used on the routes as compared to the total number of fleet units, etc.). The proposed indicator of availability of the rolling stock considers not only the natural number of vehicles, but also their passenger capacity, the indicated significant technical and operational indicators of the vehicle fleet. The basis for assessing the carrying capacity of the rolling stock fleet is a conventional one-hundred-seat bus, which performs transportation on routes with an average operating speed. For real buses, this basic unit is adjusted in accordance with real travel speeds and the prevailing values of technical and operational indicators. A similar adjustment is performed for real trolleybuses and tram cars, which makes it possible to level the operational differences in the rolling stock of various types of UPT to compare them in terms of carrying capacity.

The methodology used in preparation of the article is based on the integrated use of scientific knowledge in the fields of applied science on operation of transport, statistics (statistical observation and accounting of the work of UPT), a comparative analysis of indicators used in various industries, in particular, in agriculture to assess the level of provision with the main production vehicles (conventional tractor), benchmarking research and development of Russian and foreign authors on the problem of improving operation of UPT.

The indicator is intended for use in development and assessment of the level of implementation of programs for development of UPT and the urban environment, analysis of the quality of transport planning and services provided to passengers, comparisons of provision with vehicles in different cities.
Control of Production Personnel when Performing Vehicle Maintenance

Published: July 2021

The objective of this article is to analyse labour discipline of production personnel when performing vehicle maintenance works. Currently, many car service enterprises practically do not control the quality of the work of the employees. These responsibilities are assigned to the lower management level – foremen, however, they are either heavily loaded with work, or are not interested in performing control functions. In addition, labour intensity of technical maintenance and repair work is set by the manufacturer at the lowest possible level, assuming that the staff is highly qualified, and the company is provided with all the necessary special tools. As a result, it is difficult or impossible for employees to meet the standards, therefore, to fulfil the plan and not lose part of the wages, they miss or do not perform part of the work paid by the client. The studies were carried out in Perm at a typical car service enterprise, which is an official dealer of a domestic car brand.

The analysis of the work of the personnel was carried out by comparing the actual work performed following the technology defined by the manufacturer. For this, video recording of all the actions of an employee was carried out. The completeness of each operation was noted, as well as the time spent. Work efficiency was assessed using Spaghetti diagrams, which indicate all movements of the performers. A methodology is presented that allows to give a final assessment of the work of locksmiths, which consists in calculating penalty points for exceeding standard time, partial execution or omission of operations. A scale for evaluating performers has been developed. The results of studies of carrying out maintenance of two identical cars are presented. The shortcomings of the production personnel are discovered and analysed. To increase labour productivity, it is possible to use the principles of lean production of the 5 «S» system. It is necessary to equip the posts with tools, issue checklists to the performers and use the movement scheme at the maintenance post, equip posts with video surveillance cameras and periodically carry out selective control of work. To motivate staff, it is necessary to revise the system of bonuses and fines, considering the results of work.
Compositional and Verbal Aspect in Greek: The Aorist Imperfect Distinction and the Article-Aspect Interplay
Authors: Dimitrova Desislava , Kabakčiev Krasimir
Published: July 2021

According to an aspectological model proposed by Kabakčiev in 1984, later developed and sophisticated, languages differ according to whether they mark aspect (perfectivity and imperfectivity) on verbs, as in the Slavic languages – among others, or through nouns/NPs featuring (non-)boundedness which is transferred onto verbs, as in the Germanic languages – among others. In this model of compositional aspect (CA), Bulgarian is a borderline case with a perfective-imperfective and an aorist-imperfect distinction and a definite article only (no indefinite), and the model is used to analyze Greek, a language exhibiting identical features. NP referents play a major role for the compositional explication of aspect. The study finds that Greek is of the same borderline/hybrid type of language as Bulgarian, featuring verbal aspect (VA) predominantly, but also peripherally CA. The aorist/imperfect distinction exists both in Greek and Bulgarian to offset the structural impact of the definite article. Analyzed are some conditions for the explication of CA in Greek and they are found similar to those in Bulgarian. However, there are specificites and differences between the two languages that must be further studied and identified. Keywords: verbal aspect, compositional aspect, definite article, article-aspect interplay, aorist-imperfect contrast
