DETERMINATION OF KINEMATIC CHARACTERISTICS OF METAL PLASTIC FLOW UNDER CONDITIONS OF AXIAL SYMMETRY OF THE DEFORMATION PROCESS
Authors: Sivak Roman , Ostrovsky Anatoliy , Zalizniak Roman
Published: June 2022

With axisymmetric deformation, the deformable body and the load have a common axis of symmetry. Such deformation occurs in numerous technological operations. About 70% of parts obtained by cold extrusion are deformed under conditions of axial symmetry.

The plane problem of the theory of plasticity is reduced to a solution in the framework of a two-dimensional statement, when the motion of points in the section of a workpiece is analyzed. Each point can move only in the section plane, and its velocity can be decomposed into two mutually perpendicular directions along the coordinate axes. For plane deformation, it is assumed that the velocity in the direction of the third coordinate axis is equal to zero.

The presence of axial symmetry allows us to confine ourselves to studying the behavior of points located on the plane of the meridional section of the workpiece. In this case, each point can move only in the section plane and its velocity can be decomposed into two orthogonal directions: along the axis and along the radius. The component of the velocity vector in the circumferential direction is equal to zero, so only four of the six independent components of the strain rate tensor remain. In this regard, axisymmetric problems of the theory of plasticity are of considerable interest from the point of view of solving applied problems.

The article discusses the possibility of using mixed Euler and Lagrange coordinates to determine the components of the strain rate tensor in plastic deformation processes characterized by the axisymmetric nature of metal plastic flow. The vector field of displacements at each point in space reflects the transformation of the initial (non-deformed) configuration into the current one, and therefore determines the configuration of the deformed body in space in a certain frame of reference. The deformation process is first considered in a single Cartesian coordinate system, and then in a cylindrical coordinate system, the use of which is more appropriate for axisymmetric deformation. It is assumed that the functions of the Euler coordinates from the Lagrange coordinates are obtained by approximating the experimental data.

Soft Power Phenomenon in Azerbaijan Foreign Policy: A Study on the Tourism Sector
Authors: Mammadov Agil
Published: June 2022

The concept of power, which is one of the most common discussion topics in the discipline of international relations, has been examined with many different dimensions, and the soft power dimension has become an important discussion and study area, especially since the Cold War. Physically, power is the efficiency achieved by using available forces. By a behavioral definition, power is the ability to change the behavior of others to achieve desired results. When we pay attention to the last centuries in the Caucasus, it is possible to say that the situation in the region has been shaped more by the axis of hard policy formation. Azerbaijan has aimed to produce foreign policy strategies by keeping the peaceful aspects in the foreground in the foreign policy formation process from its independence to the present day. While doing this, tourism emerges as a soft power element in foreign policy. One of the main problems of Azerbaijan’s foreign policy after independence has been the Karabakh problem. Azerbaijan’s gaining sovereignty after the 44-day war with Armenia in 2020 has led to the emergence of new opportunities. The natural beauties, historical artifacts, and cultural riches, which were liberated from the occupation after the 44-day war in the autumn of 2020, reveal the importance of tourism in Azerbaijan. Another important problem of the Azerbaijani economy is the country’s dependence on oil. Tourism can play the role of an alternative economy for diversifying the economy. Considering these factors, the present study aims to reveal the soft power tendency in Azerbaijan’s foreign policy-making process. In the process of scientific creation of the study, research was made based on the official data of the State Statistical Committee of Azerbaijan.

Kartoittavan katsauksen kirjallisuushauissa kuntoutuksen koulutuksesta Suomessa löytyi yhteensä 50 tutkimusta, selvitystä ja raporttia. Ajallisesti tarkasteltuna tutkimusten määrässä oli nouseva trendi. Katsauksessa kuntoutuksen ammattilaisten joukkoa oli rajattu ja koulutusasteista tutkimuskohteina esiintyivät enemmistönä ammattikorkeakoulut. Vähiten tutkittu osa-alue oli moniammatillisuuden toteutuminen kuntoutuksen koulutuksissa. Kuntoutuksen koulutuksen kehittämisessä tulisi erityisesti kiinnittää huomiota teknologiaan ja digitalisaatioon, työelämäyhteistyöhön sekä moniammatilliseen ja monialaiseen yhteistyöhön. Moniammatillisuuden edistämiseksi kuntoutuksen ammattilaisilla tulisi olla yhteinen tietoperusta ja teoreettisten käsitteiden käyttö. Tämän vuoksi kuntoutusalojen koulutuksissa tulisi olla yhteisiä opintoja ja pedagogisia ratkaisuja.
Fertigteile aus Recyclingbeton – Ergebnisse des Forschungsprojektes SeRaMCo/Precast Elements with Recycled Concrete – Results of the research project SeRaMCo
Authors: Glock Christian , Hondl Timo
Published: June 2022

Der Beton- und Stahlbetonbau nutzt heute in Deutschland überwiegend natürliche Ausgangsstoffe aus endlichen Primärressourcen, obwohl der Bausektor aufgrund seines hohen Abfallaufkommens von in Deutschland jährlich 3,7 t pro Einwohner (2018) [1] für geschlossene Stoffkreisläufe geeignet wäre. Um die Kreislaufwirtschaft im Beton- und Stahlbetonbau zu fördern, wurde im Rahmen des internationalen EU-Verbundforschungsprojektes „Secondary Raw Materials for Precast Concrete Construction“ (kurz SeRaMCo) in den Jahren 2017 bis 2021 die Umsetzung der Kreislaufwirtschaft für die Anwendung im Betonfertigteilbau mit hohem Praxisbezug entlang der gesamten Wertschöpfungskette untersucht. Forschungsschwerpunkte der beteiligten europäischen Vertreter aus Wissenschaft, Wirtschaft und öffentlicher Hand waren dabei die Aufbereitung von Bauschutt, die Herstellung von Zement aus Brechsanden sowie die Produktion von Betonfertigteilen aus rezykliertem Splitt und Zement. Zur Demonstration der industriellen Umsetzbarkeit wurden zahlreiche Produkte unter Einbeziehung der gesamten Wertschöpfungskette hergestellt und abschließend mit dem Bau von Pilotbauwerken im öffentlichen Raum auch baulich umgesetzt.
Einflüsse von Außentemperaturen auf die Produktivität von Bauausführenden/Effects of temperatures on the productivity of construction workers
Authors: Kynast Luisa , Schwerdtner Patrick
Published: June 2022

Den Schwerpunkt des Beitrags bildet die Untersuchung des Einflusses hoher Lufttemperaturen auf die Produktivität bei der Bauausführung unter besonderer Berücksichtigung des „Faktors Mensch“. In der Literatur dominiert die Untersuchung der Auswirkungen von winterlichen Witterungsbedingungen auf die Bauausführung (Winterbau). Vor dem Hintergrund des Klimawandels ist jedoch zukünftig mit milden Wintern und heißen Sommern zu rechnen. Dies führt einerseits dazu, dass zwar im Winter uneingeschränkt(er) gebaut werden kann, anderseits ziehen Hitzewellen im Sommer Beeinträchtigungen bei der Bauausführung nach sich, die häufig keinerlei vertragliche beziehungsweise kalkulatorische Berücksichtigung durch die Vertragsparteien erfahren. Die vorliegende Untersuchung setzt an dieser Forschungslücke an und soll somit einen Beitrag zur Berücksichtigung von Effekten hoher Lufttemperaturen auf die Bauausführung und Bauausführende (Faktor Mensch) leisten.

Authors: Brunner Adrian , Markiewicz Roman , Pistrol Johannes , Adam Dietmar
Published: June 2022

Vier der im Zuge der U-Bahn-Erweiterung der Linie U2 in Wien im Jahr 2008 neu eröffneten Stationen decken einen Großteil ihres Heiz- und Kühlbedarfs seit beinahe eineinhalb Jahrzehnten aus geothermischer Energie, welche durch Massivabsorber in Form von Energieschlitzwänden, Energiepfählen und Energiebodenplatten der Stationsgebäude gewonnen wird. Da es sich zum Zeitpunkt der Errichtung weltweit um das erste Infrastrukturbauwerk dieser Art und Dimension handelte, wurde ein Schlitzwandelement der Station Taborstraße mit zahlreichen Messsensoren ausgestattet, um Datensätze des thermo-mechanischen Langzeitverhaltens dieser Bauteile zu generieren. Kontinuierliche Messungen mit automatischer Datenaufzeichnung erfolgten zunächst von April 2008 bis Mai 2011. Im Oktober 2020 wurden die Messungen mit der bestehenden Sensorik wieder aufgenommen, wobei die Messungen manuell im Monatsrhythmus erfolgen, um einen langfristigen Vergleich der Messdaten zu ermöglichen sowie eine Beurteilungsgrundlage von Auswirkungen des geothermischen Betriebs auf die konstruktiven Bauteile zu schaffen.

 

Der vorliegende Beitrag gibt einen Überblick über die Station Taborstraße mit Fokus auf die thermisch aktivierten Bauteile und deren Instrumentierung. Ein Vergleich der messtechnisch erfassten genutzten Energie mit dem prognostizierten Wärme- und Kältebedarf wird im Zusammenhang mit den Energiedaten diskutiert. Darüber hinaus wird das Temperatur- und Dehnungsverhalten der beobachteten Energieschlitzwand anhand der über einen Zeitraum von rund 14 Betriebsjahren erhobenen Messdaten beschrieben.

Lubricants minimise friction and wear in rubbing contacts by reducing metal–metal contact, removing wear debris, and carrying away frictional heat. They may also prevent rusting and with liquid lubricants remove heat. Lubricants may be solid, such as graphite, molybdenum disulphide, polytetrafluoroethylene and talc; or gaseous, commonly air; but the principal lubricants are liquids such as mineral oil, or the semi-solid greases formed from liquids by the use of thickening agents.

Published: June 2022

This article is dedicated to women writers of the 1980s, who are an integral and important part of Chinese literature. In the works created in the mid-80s, the writers not only described the horrors of the recent past of the people, but also tried to analyze and observe the flaws that still persist in the society that hinders the development of the country. As a result, journalism has developed rapidly, and the direction of "search for roots" has emerged. In the literature, the development of this direction was a peculiar necessity, because after the Cultural Revolution, many writers realized the poverty and backwardness of existing literature and actively sought to take literature to a new level.

Complementarity of solution and solid state mechanochemical reaction conditions demonstrated by 1,2-debromination of tricyclic imides
Authors: Štrbac Petar , Margetić Davor
Published: June 2022

The solution phase 1,2-debromination of polycyclic imides using the Zn/Ag couple was successfully transferred to solid state mechanochemical conditions. The Zn/Ag couple was replaced by the Zn/Cu couple which was prepared without any metal activation by in situ ball milling of zinc and copper dusts. The advantage of the ball milling process is that the whole procedure is operationally very simplified. The reactive alkene generated was trapped in situ by several dienes and the respective Diels−Alder cycloadducts were obtained. It was demonstrated that mechanochemical milling offers complementary conditions to solution (thermal) reaction by allowing chemical transformations to proceed which were not possible in solution and vice versa.

Semiparametric Estimation of Average Treatment Effect on the Treated: Application of Anti-Graft Act
Authors:   The Korean Data Analysis Society, Song Hosin
Published: June 2022

In this study, Abadie(2005)’s semiparametric difference-in-difference(DID) and propensity score matching DID methods are implemented to estimate the average treatment effect on the treated(ATET) of the Anti-Graft Act on the expenditure on congratulations and condolences(ECC). Both approaches are semiparametric since they do not require a specific functional form specification of the outcome variable. By following Abadie(2005), the ATET can be estimated by using observed outcomes at before and after policy intervention, treatment indicator and propensity score of all observations. On the other hand, the propensity score matching DID is a very intuitive method to estimate ATET since it can find a counterfactual control for each treated unit. Abadie’s semiparametric DID estimate is -0.06 while the propensity score matching estimate is -0.12. However, the statistical significance is found only in the latter estimation result. It implies that the treatment group are expected to reduce the expenditure on congratulations and condolences by 12.8 percent less than the control group if the control group would be exposed to the treatment.

Published: June 2022

Big data is being collected across all sectors of society, and the education sector is no exception. The generalization of big data can lead to educational policy decisions based on information derived from big data and enhance the effectiveness of education. Big data in the education field can be roughly divided into three types according to its depth and utilization: macro-level data that includes student (including parents) level, teacher level, and school level data generated and collected by educational institutions; meso-level data for text such as students’ forum discussions, postings, and essay; and small-scale data (such as clickstream) for recording learning activities. In this study, a part of the data from the Korea Education Employment Panel Wave II was fitted to the deep learning model as an example of the spread of the use of big data in education. Using a neural network model including two hidden layers with 140 variables of various student levels such as learning, leisure, and family life as the input layer, the level of student career maturity was predicted and the prediction performance was compared with the multinomial logistic regression model. Discussions related to education big data analysis using deep learning models are presented along with the analysis results.

Dinamika Eksistensi Perempuan dan Kritik Sosial dalam Sastra (Analisis Struktural Trilogi Novel Ronggng Dukuh Paruk karya Ahmad Tohari)
Authors: Permatasari Delmarrich Bilga Ayu
Published: June 2022

Trilogi Ronggeng Dukuh Paruk karya Ahmad Tohari mampu meluruhkan hegemoni patriarki yang biasanya tidak diangkat oleh sastrawan laki-laki sekaligus dapat menyuarakan problematika politik. Dengan menggunakan pendekatan struktural, didapatkan beberapa topik pengangkatan kritik sosial dalam trilogi ini. Dari penganalisisan novel pertama hingga terakhir, secara runtut didapatkan dinamika kritik sosial. Awal pengisahan dalam novel yang pertama, kritik sosial kebangsaan dihadirkan sekali yaitu berupa animisme dan kemiskinan. Selanjutnya, kritik sosial feminis ditonjolkan dengan hadirnya kritikan terhadap Indonesia yang berupa: pengadaan prostitusi tersamar pada lembaga tari daerah, praktik jual-beli tubuh perempuan, penistaan hak asasi perempuan, dan penyimpangan norma dan perilaku seksual. Kekisruhan politik dan kekerasan rezim orde baru menyelingi kritik feminis yang berupa perdagangan perempuan pasca konflik reformasi. Hingga akhirnya kritik sosial diakhiri dengan pengaruh problematika terhadap individualitas bangsa. Pada akhirnya melalui penelitian ini, dapat disimpulkan bahwa Ahmad Tohari mengusung gerakan feminis dalam trilogi Ronggeng Dukuh Paruk dengan cara yang dinamik. Hal ini dapat dijelaskan dengan hadirnya lima dari sembilan topik kritik sosial yang mengandung problematika perempuan di Indonesia yang diselipi problematika kebangsaan. Meski mengusung hegemoni patriarki sebagai tolakan dasar pengisahan, ia tetap menghadirkan problematika kebangsaan yang terjadi di ranah Nusantara. Pernyataan ini diperkuat dengan hadirnya kritik sosial berupa: animisme dan kemiskinan, kekisruhan politik, kekerasan rezim orde baru, dan pengaruh problematika bangsa terhadap individualitas.
Lecturers’ Reflections on Emergency Remote Teaching and Learning at a University in South Africa During COVID-19 Lockdown
Authors: Legg-Jack Dagogo William , Ndebele Clever
Published: June 2022

The outbreak of the COVID-19 pandemic came with a lot of disruptions which saw so many organisations and institutions shut down. Part of the changes brought about by the pandemic was the closure of educational institutions globally, thereby forcing the migration to emergency remote teaching and learning. Whilst some nations grappled with the challenges associated with this shift in the mode of teaching and learning, others tapped into the opportunities inherent in it. This study located in the interpretive paradigm employed a qualitative case study design that explored lecturers’ reflections on emergency remote teaching and learning at a university in South Africa during the intense stages of the COVID-19 pandemic. The Technology Acceptance Model was employed as a lens to make meaning of how lecturers perceive emergency remote teaching and learning in the science and technology cluster. The sample for the study consisted of nine participants, recruited from Science and Technology cluster, representing Biological/Life Sciences, Natural Sciences, Physical Sciences and Technology Education faculties. The sample was selected through purposive and convenience sampling. Findings from the study revealed both challenges and opportunities for emergency remote teaching and learning. The challenges identified included, lecturers’ lack of readiness, students’ internet-related issues, and inability to execute practical tasks online. The positive aspect included improved skills in the use of ICT and diverse online platforms for both lecturers and students. Based on the findings, the study recommends that students, especially those from disadvantaged backgrounds be provided with the necessary ICT infrastructure to ensure their effective participation in online learning.

GENGA. II. GPU Planetary N-body Simulations with Non-Newtonian Forces and High Number of Particles
Authors: Grimm Simon L. , Stadel Joachim G. , Brasser Ramon , Meier Matthias M. M. , Mordasini Christoph
Published: June 2022

We present recent updates and improvements of the graphical processing unit (GPU) N-body code GENGA. Modern state-of-the-art simulations of planet formation require the use of a very high number of particles to accurately resolve planetary growth and to quantify the effect of dynamical friction. At present the practical upper limit is in the range of 30,000–60,000 fully interactive particles; possibly a little more on the latest GPU devices. While the original hybrid symplectic integration method has difficulties to scale up to these numbers, we have improved the integration method by (i) introducing higher level changeover functions and (ii) code improvements to better use the most recent GPU hardware efficiently for such large simulations. We added treatments of non-Newtonian forces such as general relativity, tidal interaction, rotational deformation, the Yarkovsky effect, and Poynting–Robertson drag, as well as a new model to treat virtual collisions of small bodies in the solar system. We added new tools to GENGA, such as semi-active test particles that feel more massive bodies but not each other, a more accurate collision handling and a real-time openGL visualization. We present example simulations, including a 1.5 billion year terrestrial planet formation simulation that initially started with 65,536 particles, a 3.5 billion year simulation without gas giants starting with 32,768 particles, the evolution of asteroid fragments in the solar system, and the planetesimal accretion of a growing Jupiter simulation. GENGA runs on modern NVIDIA and AMD GPUs.
Formation and Abundance of Late-forming Primordial Black Holes as Dark Matter
Authors: Chakraborty Amlan , Chanda Prolay K , Pandey Kanhaiya Lal , Das Subinoy
Published: June 2022

We propose a novel mechanism where primordial black hole (PBH) dark matter is formed much later in the history of the universe, between the epochs of Big Bang nucleosynthesis and cosmic microwave background photon decoupling. In our setup, one does not need to modify the scale-invariant inflationary power spectra; instead, a late-phase transition in a strongly interacting fermion–scalar fluid (which occurs naturally around redshift 106 ≤ z

T
≤ 108) creates an instability in the density perturbation as the sound speed turns imaginary. As a result, the dark matter perturbation grows exponentially in sub-Compton scales. This follows the immediate formation of an early dense dark matter halo, which finally evolves into PBHs due to cooling through scalar radiation. We calculate the variance of the density perturbations and the PBH fractional abundances f(M) by using a nonmonochromatic mass function. We find that the peak of our PBH mass function lies between 10−16 and 10−14 solar mass for z

T
≃ 106, and thus that it can constitute the entire dark matter of the universe. In PBH formation, one would expect a temporary phase where an attractive scalar balances the Fermi pressure. We numerically confirm that such a state indeed exists, and we find the radius and density profile of the temporary static structure of the dark matter halo, which finally evolves into PBHs due to cooling through scalar radiation.

HESS J1843–033 is a very high energy gamma-ray source whose origin remains unidentified. This work presents, for the first time, the energy spectrum of gamma rays beyond 100 TeV from the HESS J1843–033 region using the data recorded by the Tibet air shower array and its underground muon detector array. A gamma-ray source with an extension of 0.°34 ± 0.°12 is successfully detected above 25 TeV at (α, δ) = (281.°09 ± 0.°10, −3.°76 ± 0.°09) near HESS J1843–033 with a statistical significance of 6.2σ, and the source is named TASG J1844–038. The position of TASG J1844–038 is consistent with those of HESS J1843–033, eHWC J1842–035, and LHAASO J1843–0338. The measured gamma-ray energy spectrum in 25 TeV < E < 130 TeV is described with

Associations of TASG J1844–038 with SNR G28.6–0.1 and PSR J1844–0346 are also discussed in detail for the first time.
Model-independent Reconstruction of Dark Energy Density from Current Observations
Authors: Mehrabi Ahmad , Vazirnia Maryam
Published: June 2022

The evolution of the dark energy (DE) density is a crucial quantity for understanding the nature of DE. Often, the quantity is described by the so-called equation of state; that is, the ratio of the DE pressure to its density. In this scenario, the DE density is always positive throughout cosmic history, and a negative value is not allowed. Assuming a homogeneous and isotropic universe, we reconstruct the DE density directly from observational data and investigate its evolution throughout cosmic history. We consider the latest Type Ia supernova, baryon acoustic oscillation, and cosmic chronometer data, and reconstruct the DE density in both flat and nonflat universes up to redshift z ∼ 3. The results are well in agreement with ΛCDM up to redshift z ∼ 1.5, but we see a weak sign of negative DE density at high redshifts.

By comparing available experimental wavelengths with the MCDHF results, the previous line identifications for the n = 5, 4, 3 → n = 2 transitions of Na vi in the X-ray and EUV wavelength range are revised. For several previous identifications discrepancies are found, and tentative new (or revised) identifications are proposed. A consistent atomic data set including both energy and transition data with spectroscopic accuracy is provided for the lowest hundreds of states for C-like ions from O iii to Mg vii.
Exploring γ-Ray Flares in the Long-term Light Curves of CTA 102 at GeV Energies

Blazar CTA 102 experienced an intense multiwavelength activity phase from 2015 to 2018; in particular, an unprecedented outburst was observed from 2016 October to 2017 February. In this work, we extract a 7 day binned γ-ray light curve from 2008 August to 2018 March in the energy range 0.1–300 GeV and identify three main outbursts. We study in detail the short-timescale variability of these three outbursts via an exponential function with parameterized rise and decay timescales. The obtained shortest rise and decay timescales are 0.70 ± 0.05 hr and 0.79 ± 0.27 hr, respectively. Based on these variability timescales, the physical parameters of the flaring region (e.g., the minimum Doppler factor and the emission region size) are constrained. The short-timescale flares exhibit a symmetric temporal profile within the error bars, implying that the rise and decay timescales are dominated by the light-crossing timescale or by disturbances caused by dense plasma blobs passing through the standing shock front in the jet region. We also find that the best-fitting form of the γ-ray spectra during the flare period is a power law with an exponential cutoff. The derived jet parameters from the spectral behavior and the temporal characteristics of the individual flares suggest that the γ-ray emission region is located upstream of the radio core. The extreme γ-ray flare of CTA 102 is likely to have been caused by magnetic reconnection.
