Prospects for development of graphic training of students of technical universities
Authors:   Urals State Transport University, Nazarova Zh. A.
Published: June 2023

This article discusses the possibility of developing graphic training for students of technical specialties in the field of information modeling (building information modeling). Currently, building information modeling are an integral part of the construction industry all over the world, and the process of implementation in the Russian Federation is underway to maintain the competitiveness of developers both in the domestic market and in construction abroad. In parallel with the introduction in the construction sector, there are attempts to adapt information modeling in other industries. Against this background, the demand for specialists in the field of information modeling has increased, employees have to retrain not only to work with new software, but also to move away from individual creativity of individual employees or departments to collective work on one project simultaneously by all employees from their workplaces (perhaps even from different cities and countries). In parallel with this, various software being created in the field of information modeling, both in Russia and abroad, most of them are initially aimed at construction, but there are also adaptation options for other fields of activity. In this regard, the issue of actual graphic training of modern specialists has arisen: now it is not enough to teach students to create drawings using CAD and read design documentation, but it is necessary to immediately prepare students for collective creativity, responsibility to the team for the changes made to the project, and most importantly — to show the principles of work in a software product for information modeling.

Authors:   Military Innovative Technopolis «ERA», Yakovleva Yu. S. , Biryukov A. N. ,   Military Academy of Logistics named after General of Army A. V. Khrulev
Published: June 2023

The article discusses the results of studies of the physical characteristics of heataccumulating building materials. Modern trends in the production and use of materials determine the need to develop new scientific and methodological devices for assessing the physical characteristics of energy-saving building materials, which will significantly improve the properties of materials, reduce their cost and improve the quality and reliability of structures and products. As such a device, the authors propose the use of a mathematical model, the statistical description of experimental data of which is linear regression. The initial substances for the formation of a microcapsulated heat-accumulating material are selected as input parameters of the system, and the output characteristics are dependent variables (specific heat of the phase transition, compressive strength). Based on the results of experimental studies and using the DataFit program.
C. McGinn. A Religion of Hate / trans. from Engl. V. A. Sergeeva
Authors:   Tyumen State University, Sergeeva V. A.
Published: June 2023

The essay examines universal hate as an alternative foundation to Christianity. According to McGinn, we should hate everyone, even those we love. It is that will enable us to avoid prejudice against individuals and groups who are not part of the inner circle of people for whom we have some sympathy. Hate is justified, natural to human and egalitarian. McGinn does not exclude love from the religion of hate. Emerging love in the background of basic universal hate becomes a more meaningful and valued feeling.

Published: June 2023

Eric Olson’s animalist view relies on the premise that person is not a fit candidate to be a substance concept, in Wiggins’s terminology. Instead, he claims, animal is what best serves as the answer to what we most fundamentally are and what determines our persistence conditions. Pro-posing a thought experiment concerning inorganic replacement, I aim to show that Olson’s animalist view cannot accommodate our very strong intuitions about such cases. My claim is then that animalism either fails on its own grounds or requires some tuning regarding what exactly an organism is and its persistence conditions. I will examine Matthew Liao’s attempt to accommodate such intuitions within an animalist view. I will also describe the basics about Olson’s animalist view but let us first look at the rough outline of my thought experiment. The essentials are as follows, the rest I will provide later, as we go along.

Decreased SIRT1 protein may promote HMGB1 translocation in the keratinocytes of patients with cutaneous lupus erythematosus
Authors: Zhou Xingyu , Qiu Yueqi , Mu Kui , Li Yaping
Published: June 2023

Background

Ultraviolet radiation causes DNA damage in keratinocytes, aggravating cutaneous lupus erythematosus (CLE). High mobility group box 1 (HMGB1) participates in nucleotide excision and may transfer from the nucleus to the cytoplasm in immune active cells and the translocation of HMGB1 may result in DNA repair defects. HMGB1 was observed to transfer from the nucleus to the cytoplasm in the keratinocytes of CLE patients. As a class III histone deacetylases (HDACs), sirtuin-1 (SIRT1) can induce HMGB1 deacetylation. Epigenetic modification of HMGB1 may lead to HMGB1 translocation.

Aims

We aimed to evaluate the expressions of SIRT1 and HMGB1 in the epidermis of CLE patients and whether decreased SIRT1 leads to HMGB1 translocation through HMGB1 acetylation in keratinocytes.

Methods

We measured the messenger RNA (mRNA) and protein expressions of SIRT1 and HMGB1 in CLE patients using real-time reverse transcription polymerase chain reaction (RT-qPCR) and western blotting. Keratinocytes were treated with SIRT1 activator resveratrol (Res) and irradiated with ultraviolet B (UVB). We detected the localization expression of HMGB1 by immunofluorescence. The apoptosis level and the cell cycle proportions were measured by flow cytometry. The acetyl-HMGB1 level was detected by immunoprecipitation.

Results

Compared to healthy controls, the mRNA and protein expressions of SIRT1 in the epidermis of CLE patients were significantly decreased and there was translocation of HMGB1 from the nucleus to the cytoplasm. In keratinocytes, UVB irradiation led to HMGB1 translocation from the nucleus to the cytoplasm. Res treatment inhibited HMGB1 translocation, attenuated the cell apoptosis induced by UVB and decreased the acetyl-HMGB1 level.

Limitations

We only treated keratinocytes with the SIRT1 activator but did not perform the relevant experiments in keratinocytes with SIRT1 knockdown or overexpression. In addition, the lysine residue site of action of SIRT1 deacetylation of HMGB1 is unclear. The specific mechanism of action of SIRT1 deacetylation of HMGB1 needs to be further investigated.

Conclusion

SIRT1 may inhibit HMGB1 translocation by HMGB1 deacetylation which inhibited the apoptosis of keratinocytes induced by UVB. Decreased SIRT1 may promote HMGB1 translocation in the keratinocytes of patients with CLE.
Limitation of fenestrated clips during clipping of middle cerebral artery aneurysm: Technical note
Authors: Degollado-García Javier , Rodríguez-Rubio Héctor A. , Bonilla-Suastegui Alfredo , Serrano-Rubio Alejandro , Nicolas-Cruz Carlos F. , Nathal Edgar
Published: June 2023

Background:

The middle cerebral artery (MCA) is a common site of cerebral aneurysms and 82.6% occur at the bifurcation. When surgery is selected as a therapeutic option, it intends to clip the neck completely because if some remnant occurs, there exists the possibility of regrowth and bleeding in the short- or long-term.

Methods:

We analyzed one drawback of the fenestrated clips of Yasargil and Sugita types to occlude the neck totally at a specific point formed by the union of the fenestra with the blades, creating a triangular space where the aneurysm can protrude, giving place to a remnant that can lead to a future recurrence and rebleeding. We show two cases of ruptured MCA aneurysms in which a cross-clipping technique occluded a broad base and dysmorphic aneurysm using straight fenestrated clips.

Results:

In both cases (one using a Yasargil clip and the other with a Sugita clip), a small remnant was visualized when fluorescein videoangiography (FL-VAG) was used. In both cases, the small remnant was clipped with a 3 mm straight miniclip.

Conclusion:

We should be aware of this drawback when clipping aneurysms using fenestrated clips to ensure a complete obliteration of the aneurysm’s neck.
Epiduritis related to IgG4 disease: A very rare cause for spinal cord compression
Authors: Gader Ghassen , Atig Fatma Ben , Jemel Nesrine , Bourgou Malek , Slimane Abdelhafidh , Ghedira Khalil , Badri Mohamed , Zammel Ihsèn
Published: June 2023

Background:

Inflammatory pseudotumors are rare, and those attributed to immunoglobulin G4 (IgG4) diseases are even less frequently encountered. Here, we reviewed 41 cases from the literature of spinal inflammatory pseudotumors due to IgG4 and have added our single new case.

Case Presentation:

A 25-year-old male presented with progressive back pain, bilateral paraparesis, and sphincter dysfunction. His deficit was attributed to MR-documented posterolateral lesion between the T5 and T10 levels for which he levels underwent a T1–T1010 laminectomy. The pathology revealed an immunoglobulin G4-related inflammatory pseudotumor. Postoperatively, the patient additionally required systemic and epidural administration of glucocorticoids.

Conclusion:

IgG4-related disease is an emerging clinical condition that rarely involves the central nervous system. Spinal inflammatory pseudotumors, including IgG4 disease, should be more commonly considered among the potential differential diagnoses of lesions compressing the spinal cord.
Descriptive surgical epidemiology of pituitary adenomas for a Hispanic population in Puerto Rico
Authors: De Jesus Orlando
Published: June 2023

Background:

Demographics and socioeconomic variables for patients with pituitary adenomas have been reported in the past. However, these studies included operated and nonoperated patients, in addition to microprolactinomas frequently diagnosed in women, revealing an elevated incidence among females. This study aimed to analyze the surgical incidence of pituitary adenomas for an adult Hispanic population in Puerto Rico over 6 years.

Methods:

A retrospective and descriptive study was performed to investigate pituitary adenoma surgical incidence (per 100,000 people) among surgically treated pituitary adenomas in an adult (18 years or more) Puerto Rico Hispanic population. All new patients diagnosed with pituitary adenomas who underwent surgery at the Puerto Rico Medical Center between 2017 and 2022 were scrutinized. Inclusion criteria required a histopathological diagnosis of pituitary adenoma. Previously operated cases and non-Hispanic patients were excluded from the study. Patient characteristics were collected, along with the type of surgical treatment, tumor size, and secretory status.

Results:

The analysis included 143 patients operated on for pituitary adenomas. Of these, 75 (52%) patients were male, and 68 (48%) were female. The median age of the patients was 56 years (range: 18–85). The average annual surgical incidence of adult Hispanic patients with pituitary adenomas was 0.73 surgeries/100,000 people. About 79% of the patients had non-functioning pituitary adenomas. About 94% of the patients were operated on using transsphenoidal surgery.

Conclusion:

There was no sex predominance for surgical-treated pituitary adenomas in Puerto Rico. The surgical incidence for adult pituitary adenoma remained stable between 2017 and 2022.

Published: June 2023

Арктическая зона Российской Федерации (АЗ РФ) характеризуется низкой плотностью населения, высоким индексом бюджетных расходов и богатой минерально-сырьевой базой. С учетом значительного наличия разрабатываемых месторождений полезных ископаемых в арктических регионах вырисовывается большой потенциал конвертации налогового потенциала бюджетов регионов в проекты, направленные в целом на сглаживание пространственной поляризации в социально-экономической сфере арктических регионов. Цель настоящего исследования состоит в оценке влияния доходного потенциала арктических регионов на динамику уровня бедности населения. Выполнены сравнительный анализ поступлений ключевых, бюджетообразующих видов налогов в бюджеты арктических регионов за период 2018‒2022 гг. Установлено, что в Чукотском, Ямало-Ненецком и Ненецком автономных округах, лидирующих по размеру доходов бюджета на душу населения, уровень бедности населения ниже среднероссийского значения. В ходе исследования рассмотрена взаимосвязь прироста доходов бюджета на душу населения и динамики уровня бедности населения в группе арктических регионов. Показано влияние промышленного освоения Арктики на показатели доходов бюджетов регионов. В фокусе внимания государственной политики в АЗРФ должно быть снижение уровня бедности в арктических регионах.

The Arctic zone of the Russian Federation (AZ RF) is characterized by a low population density, a high index of budget expenditures, and a rich mineral resource base. Taking into account the significant presence of mineral deposits being developed in the Arctic regions, there is a great potential for converting the tax potential of regional budgets into projects aimed at smoothing spatial polarization in the socio-economic sphere of the Arctic regions in general. The purpose of this study is to assess the impact of the income potential in the Arctic regions on the dynamics of the poverty rate of the population. A comparative analysis of receiving the key budget-forming types of taxes to the budgets of the Arctic regions for the period 2018-2022 was carried out. It is established that in Chukotka, Yamal-Nenets and Nenets Autonomous Okrugs, which are leading in terms of budget revenues per capita, the poverty rates of the population were below the national average. The study examines the relationship between the increase in budget revenues per capita and the dynamics of the poverty rate of the population in the group of Arctic regions. The influence of industrial development of the Arctic on the indicators of regional budget revenues is shown. The focus of state policy in the Russian Arctic should be on reducing the poverty rate in the Arctic regions.

Published: June 2023

This study aims to synthesize and characterize silver particles using Porang leaf extract (Amorphophallus muelleri Blume) and determine the selectivity of silver particles as mercury metal ion detectors. The study employed Porang leaf extract as a bioreductor and stabilizer, 0.01M AgNO3 solution as a precursor, and HgCl2 salt solution and PbCl2 salt solution as standard salt solutions to be tested for selectivity. The 2 g of Porang leaves used were cleaned, cut into pieces, allowed to stand at room temperature for three days, and mashed. Porang leaf powder was added with 50 mL of demineralized water and then heated for 15 minutes at a solution temperature of 80°C. The reaction of silver particle formation was carried out by adding Porang leaf extract and AgNO3 0.01M in variations of 1:3, 1:4, 1:5, 1:6, and 1:7, then irradiating under indirect sunlight for 15 minutes. The reaction results of a mixture of colloidal extract and AgNO3 solution showed a change in color to brownish-yellow. The color change indicated the formation of silver particles. The silver particles were then characterized with a UV-Vis spectrophotometer after 15 minutes of heating, 1 hour, and 5 hours at room temperature. The results obtained with colloidal silver particles can be synthesized with a bioreductor of Porang leaf extract (Amorphophallus muelleri Blume) with optimum variations of 1:3 and 1:4. The PSa results obtained in the mixture of silver particles formed were micro-nano-sized silver particles. The results of silver particles tested against metal ions showed that silver particles selectively detect Hg (II) metal ions in HgCl2 solutions compared to Pb (II) metal ions in PbCl2 solutions.

Authors: Milenia Cinthia Junita , Lestari Lestari , Pebriano Valentinus
Published: June 2023

Most human activities are carried out in an indoors space. The room as an activity support facility must be able to provide a sense of comfort and safety and provide the health impacts needed by its occupants. Unhealthy working conditions can cause SBS (Sick Building Syndrome). SBS is a health problem and discomfort during activities in the room, which gradually disappears when the room user leaves the building. SBS causes a decrease in room user’s health, comfort, and productivity. To prevent this, identification of indoor health and comfort or IHC based on Greenship Interior Space is required. The object of this research is the Tanjungpura University Library, which has fulfiled the green construction criteria in terms of previous research. The study used an evaluative method by measuring the assessment referring to the Greenship Interior Space version 1 standard with field observations, simulations, manual calculations, and evaluation interviews. The results of analysis shows that the building achieves a score of 14 out of the maximum score of 28 with a value of 50%. The building successfully fulfilled prerequisite criteria, CO2 levels, chemical pollutants, biological pollutants, visual comfort, views from the outside and sunlight, and user comfort. It is hoped that the research results can be proposed as the right strategy to improve indoor health and comfort conditions at the Tanjungpura University Library building.

The city of Mempawah, also known as the earth of galaherang, has lots of tourist destinations.  This is because the it has regional characteristics in the form of land and coastal islands with seas. There is a potential beach tourism destination in there which has mangrove ecosystem in it, namely Tanjung Burung Beach.  However, the current condition of it is still not optimal due to a lack of supporting facilities as an ecotourism area, which causes activities in it to become monotonous and less attractive. In an effort to maximize the potential of areas that have characteristics in the form of sandy and muddy soils, outbound tourism areas can be designed with attractive activities and can be carried out in all types of environmental conditions.  The design of the Mempawah City Tanjung Bird Beach aims to create a playground for visitors that is formed based on the potential and problems of each by adjusting the playings that can be applied to take advantage of the surrounding natural conditions.  The design of this outbound tourism area focuses on the Tanjung Burung Beach area using the glass box design method which is carried out sequentially to produce an attractive outbound tourism design concept by applying ecotourism principles to outbound play spaces to minimize damage and preserve the surrounding environment to make it a sustainable tourist area.
DARI REALITA MENJADI WACANA: REPRESENTASI PANOPTISISME PADA PERENCANAAN KOTA PROBOLINGGO
Authors: Shabri Sayyidah , Kusdiwanggo Susilo , Yusran Yusfan Adeputera
Published: June 2023

Kota Probolinggo merupakan salah satu kota peninggalan zaman penjajahan Belanda. Menurut Hidayat & Widriyakara (2018), Kota Probolinggo menerapkan bentuk pengawasan panoptikon. Namun definisi panopticon tersebut tidak sepenuhnya terepresentasikan secara fisik pada tata Kota Probolinggo. Penelitian ini bertujuan untuk mengungkapkan bahwa Kota Probolinggo tidak hanya merupakan bentuk kota yang menerapkan pengawasan fisik tetapi juga menggambarkan panoptisisme. Dengan menggunakan analisis deskriptif sinkronis-diakronis, penelitian ini mendeskripsikan sejarah perkembangan Kota Probolinggo sebelum tahun 1743, 1743-1850, 1850-1880an, dan 1880an-1940 untuk menggambarkan bentuk kekuasaan dan kendali panoptisisme pada masa itu dan kaitannya dengan morfologi Kota Probolinggo saat ini.FROM REALITY TO DISCOURSE: REPRESENTATION OF PANOPTICISM IN PROBOLINGGO CITY’S PLANNING Probolinggo City is one of the heritage cities of the Dutch colonial era. According to Hidayat & Widriyakara (2018), the City of Probolinggo represents a form of panopticon surveillance. However, the definition of the panopticon only partially means physically in the form of Probolinggo City. This research aims to reveal that the City of Probolinggo is not only a form of city that applied physical surveillance but also portrays panopticism. Using synchronic-diachronic descriptive analysis, this study describes the history of the development of Probolinggo City before 1743, 1743-1850, 1850-the 1880s, and 1880s-1940 to describe the form of power and control of panopticism at that time and its relation to the morphology of Probolinggo City today.
Formation of carbon-induced nitrogen-centered radicals on titanium dioxide under illumination

Published: June 2023

Titanium dioxide is the most studied photocatalytic material and has been reported to be active for a wide range of reactions including oxidation of hydrocarbons and reduction of nitrogen. However, the molecular-scale interactions between the titania photocatalyst and dinitrogen are still debated, particularly in the presence of hydrocarbons. Here, we used several spectroscopic and computational techniques to identify interactions between nitrogen, methanol, and titania under illumination. Electron paramagnetic resonance spectroscopy (EPR) allowed us to observe the formation of carbon radicals upon exposure to ultraviolet radiation. These carbon radicals are observed to transform into diazo- and nitrogen-centered radicals (e.g., CHxN2* and CHxNHy*) during photocatalysis in nitrogen. In situ infrared (IR) spectroscopy under the same conditions revealed C-N stretching on titania. Furthermore, density functional theory (DFT) calculations reveal that nitrogen adsorption and the thermodynamic barrier to photocatalytic nitrogen fixation are significantly more favorable in the presence of methanol or surface carbon. These results provide compelling evidence that carbon radicals formed from the oxidation of hydrocarbons interact with dinitrogen, and suggest that the role of carbon-based ``hole scavengers'' and the inertness of nitrogen atmospheres should be reevaluated in the field of photocatalysis.
Biocatalytic approach to the chemoselective acylation of sesquiterpene lactones from chicory: a pathway to novel ester derivatives
Authors: RODRIGUEZ MOSHEIM Juan , Ruggieri Francesca , Humeau Catherine , Hance Philippe , Willand Nicolas , Hilbert Jean-Louis , Heuson Egon , Froidevaux Rénato
Published: June 2023

In this study, we explore the use of the immobilized lipase Novozym 435 in the selective acylation of chicory sesquiterpene lactones (STLs) - lactucin (Lc), 11β,13-dihydrolactucin (DHLc), lactucopicrin (Lp), and 11β,13-dihydrolactucopicrin (DHLp) - using aliphatic vinyl esters as acyl donors. Despite the scarcity of these STLs due to their challenging extraction process and high cost, our results demonstrate the broad applicability and very high efficiency of this method. Furthermore, this methodology enables the selective acylation of the primary alcohol without transesterifying the existing ester in the substrates (Lp and DHLp). We also describe the enzyme-substrate binding modes in the acylation reactions with STLs, as well as the nature of their interactions with crucial amino acid residues at the active site, providing further insight into the potential of this approach. This study forms a foundation for the tailored functionalization of STLs, offering possibilities for the synthesis of STL derivatives with significant potential applications as pharmaceuticals or biocontrol agents.

The article presents one of the topics generated by a thematic analysis of data collected through a focus group process within the scientific research project LGBT (In)Visibility in School: The Educators’ Perspective, which focused on the taboo position of sexual and gender diversity within the education system. In four focus groups conducted with secondary school educators in Zagreb, the participants identified certain key factors in perpetuating such a position: the understanding of the child/student as an innocent being whose sexual education should begin at a time that educators themselves are unable to determine, the perception of parents as barriers to the inclusion of topics of sexual and gender diversity in the curriculum, and the absence of a systematic, LGBT-inclusive approach to teaching about sexuality. The concluding part of the article discusses the limitations of the research conducted and makes recommendations for future empirical and practical coverage of this topic.
Success in Education by Defying Great Odds: A Positive Deviance Analysis of Educational Policies
Authors: Ponte Eva
Published: June 2023

EEducation is seen as a resource at a global level but is currently considered to be in crisis in many parts of the world. This constitutes a significant drawback in terms of humanity’s prosperity and well-being since education is the key not only to an educated workforce but also to humane, collaborative, and caring societies. Even within this dim landscape, there are certain educational systems that defy the odds and perform significantly higher than their otherwise comparable systems. This paper proposes using an unusual lens for educational policy comparative studies, that of positive deviance, to aid us in progressing towards a more stable educational state of affairs. Using a positive deviance methodology, which focuses on learning what is working well in systems that defy and overcome substantial challenges, this study investigates the patterns, attitudes, and actions of three selected cases: Massachusetts as a positive deviant in the US, Estonia as a positive deviant in Europe, and Castile-Leon as a positive deviant in Spain. The purpose is, by analysing educational policies, laws, and other related documents, to find commonalities that explain why these systems outperform others. The results of the comparative analysis pinpoint areas and strategies informative to those leading struggling educational systems, such as a strong commitment to equity and justice, placing teachers at the centre of reforms, using assessment as a tool for process monitoring and summative inquiry, and making preschool education accessible to all.
Chronotypes, Disruptive Behaviour, and Schedules in Classrooms: ‘Morningness’ and Psychomotor Agitation
Authors: Figueiredo Sandra
Published: June 2023

This empirical cross-sectional study explored the effect of chronotypes on classroom behaviour. One hundred and forty young Portuguese children, from 1st to 4th grades, were examined regarding their chronotype and disruptive behaviours occurring in the classroom. Three groups of chronotypes (i.e., morning, intermediate and evening) were identified. The Chronotype Questionnaire for Children evaluated the chronotype of children, and the Conners Scale - reduced version for teachers (self-report) identified the frequency of the following behaviours in the classroom: psychomotor agitation, inattention, and opposition. Multivariate analysis of variance and analysis of regression parameters showed that morning children are more agitated and impulsive compared to evening peers. Concerning academic achievement, students did not differ in the subjects Portuguese and Mathematics for both semesters when considering chronotype and controlling for covariates such as age and gender. Parental qualifications appeared as an influential covariate for the chronotype effect in disruptive behaviour. This evidence addresses the contributions of school policies and family supervision regarding young children: children have earlier evening chronotypes; chronotypes impact specific disruptive behaviours in the classroom; parents’ education influences the sleep habits and behaviours of children in school; parents and schools need more support and evidence to correctly identify children’ chronotypes, to understand how chronotype and sleep habits affect behaviours in the classroom, and to recognise that more studies should be replicated attending to the contextual factors of health outbreaks and war conflict. With reliable data, this study highlights concerns and novelties for education and psychology.

Published: June 2023

The aim of this article, based on an analysis of the political system of Bosnia and Herzegovina and the overall political situation in the country, is to assess the results of the general elections held there on October 2, 2022. These elections were probably the most watched elections of 2022, mainly because of the expected accession negotiations and the granting of the status of a European Union candidate country. The general election results were supposed to indicate whether Bosnia and Herzegovina is ready to join the ranks of developed democratic countries and whether it has finally become a functioning multi ethnic state. The methods of analysis, synthesis, deduction, induction, and generalization were used to achieve the set goal. In the end, we will point out the impact of the election results on the current political situation, which, however, does not foresee any changes compared to the current situation in Bosnia and Herzegovina.

Distribution tasks represent a group of optimization problems, the goal of which is usually to minimize the total cost of transporting goods or people within various complex logistics processes. In the field of general evacuation, transport tasks appear to be a suitable tool for planning the optimal way of transporting evacuees from boarding points to evacuation centres. The aim of the paper is to demonstrate the possibilities of optimization procedures for distribution problems with a focus on planning and managing the transport planning in the area evacuation process, in which the HaZZ units can also be deployed as an assistance element, but rather the DHZ or DHZO units. The paper contains a proposal for the transportation of residents of a micro-region threatened by a flood during their evacuation to designated evacuation centres, supported by optimization calculations.
Stanovenie únavovej pevnosti zvarových spojov ocele S960MC zváraných laserovým lúčom
Authors:   University of Žilina, Frátrik Martin , Mičian Miloš
Published: June 2023

The work deals with determining the fatigue strength of butt-welded joints of S960MC steel. The fatigue strength of two versions of laser beam welded joints as well as the base material was assessed. To reduce the notch effect of the weld beam, the assessed weld joints were produced in a variety of methods utilizing filler material and additional dressing of the weld beam. The measurements determined variations in each type. The value of the fatigue strength decreased by 50 % to 67 % with respect to the base material, indicating that the notch effect of the weld joint had an impact on the value of the fatigue limit. Despite having relatively low fatigue strengths, both values meet normative standards and can be used in practical circumstances.

The article is the next step in the ongoing research regarding the incorporation of the proposed bulk material turnstile assembly into an existing production line serving the food industry for bagging powdered milk. The main goal of this contribution is the presentation of the structural design and related technical calculations of the screw manipulator as part of the turnstile for loose materials. The proposed mechanism will enable precise manipulation of the turnstile, especially when it is necessary to clean the pipe connected to the turnstile. Such handling is relevant nowadays due to increasing the safety of maintenance of machines and equipment and due to reducing the physical load of maintenance workers. The results prove the appropriateness of the use of the given structural design and are the basis for further research in the given area. The results will be implemented in the form of boundary conditions for the numerical analyses of the connecting elements of the frame carrying the entire carriage with the turnstile (the frame forms a path for the carriage) and also for numerical calculations of the frame itself. The goal is to achieve a state where the entire structure is safe for the operator during maintenance and also for its surroundings during normal operation.
