On the well-posedness of nonlocal boundary value problems for a class of systems of linear generalized differential equations with singularities
Authors: Akhalaia Shota , Ashordia Malkhaz , Talakhadze Mzia 
Published: October 2022

Abstract
The well-posed problem for a nonlocal boundary value problem is considered for a singular system of linear generalized ordinary differential equations. The considered system is analogous to the system corresponding to the n-order ordinary differential equation. Along with the standard well-posed question, there is considered the so-called conditionally well-posed one. The effective sufficient conditions are established for both problems.

Published: October 2022

Abstract
Complex uncertain variables are measurable functions from an uncertain space to the set of complex numbers and are used to model complex uncertain quantities. In this paper, we introduce the deferred-statistically convergence concepts of complex uncertain sequences, deferred-statistically convergence almost surely, deferred-statistically convergence in measure, deferred-statistically convergence in mean and some relationship among them are discussed.
Three-dimensional finite element analysis and research of leakage magnetic field of flake, pit, through-hole defect in petroleum pipelines
Authors: Zhou Feng , Chen Yu , Zhao Han , Hu Heng 
Published: October 2022

AbstractFlake, pit and through-hole defects are the three common types of defects in oil pipelines. In practical testing applications, it is necessary to clarify the magnetic leakage characteristics of different defects and set reasonable detection points to distinguish different types of defects accurately and quantify the degree of each defect precisely. In this paper, the leakage magnetic field of flaky, pitted and through-hole tube wall defect is analyzed. Using three-dimensional finite element simulation, the spatial stereo model of leakage magnetic field is inverted by extracting the data of characteristic nodes. The distribution of the leakage magnetic field in space, for the radial and circumferential components is obtained. On this basis, the effect on the main components of magnetic leakage field at different locations in space is determined, and the best of placing a potential sensor for detecting three kinds of defects in space are derived. This provides a basis for determining sensor locations in magnetic leakage detection devices, inverting defect models from multi-sensor data and accurately quantifying the degree of defects.

Published: October 2022

Abstract
Die hohe Leistungsdichte eines elektrischen Antriebs wird in der Regel über eine hohe maximale Rotordrehzahl erreicht. Dies erfordert nicht lösbare Fügeverbindungen sowie thermisch unterstützte Montageprozesse. Der Einsatz einer Rotorwelle, Wuchtscheibe und Magnetfixierung mit federndem Verhalten ermöglicht den Entfall thermischer Prozesse sowie die Demontage treibhausgasintensiver Magnete. Potenziale sowie Herausforderungen dieser neuen Rotorkomponenten werden in diesem Beitrag vorgestellt.

Abstract
In industriellen Montage- und Logistikprozessen führen repetitives Tragen schwerer Lasten, Überkopfarbeiten oder Zwangshaltungen zu starken körperlichen Belastungen, die hohe Personalausfallquoten und geringe Arbeitsattraktivität zur Folge haben. Dieser Beitrag orientiert sich am Operator-5.0-Gedanken und stellt ein neuartiges Konzept für den kombinierten Einsatz von sensorischen Exoskeletten und fahrerlosen Transportfahrzeugen mit dem Ziel verbesserter Arbeitsergonomie und -produktivität vor. Aufbauend auf den funktionalen und prozessualen Anforderungen werden eine Systemarchitektur und Steuerungssoftware sowie intelligente Methoden zur Mensch-Technik-Interaktion vorgestellt. Dabei werden zum einen eine automatisierte, prozess- und mitarbeiterspezifische Materialbereitstellung und zum anderen eine informatorische und physische Verbesserung der Arbeitsergonomie verfolgt. Das entwickelte Konzept wird im Beitrag durch exemplarische Anwendung auf Lager- und Montageprozesse im Automobilumschlag validiert.

Abstract
In der Diskussion um die Folgen von Industrie 4.0 auf die Gestaltung von Arbeit und des demografischen Wandels auf das Erwerbspersonenpotenzial ist häufig die Rede von Assistenzsystemen. Mit ihrem Einsatz werden verschiedene Hoffnungen und Befürchtungen verbunden. Aktuelle Assistenzsysteme fokussieren meist auf die Unterstützung zur korrekten Ausführung einer Tätigkeit. Das Nachahmen von Arbeitsschritten ist wenig nachhaltig. Vielmehr sollten Lernprozesse bei den Beschäftigten initiiert werden. Welche Gestaltungsdimensionen für eine lernförderliche Entwicklung eines digitalen Assistenzsystems zum Tragen kommen sollten, ist Thema des folgenden Beitrags.
Entwicklung eines Condition-Monitoring-Systems für Niederspannungsmotoren
Authors: Reuter Thomas , Schmidt Jens , Grundmann Andreas 
Published: October 2022

AbstractDer Verbrauch von elektrischen Antrieben in der Industrie und dem verarbeitenden Gewerbe beträgt in Deutschland fast zwei Fünftel des gesamten Stromes. Somit werden den Elektromotoren eine Schlüsselrolle bei der Energieeinsparung zugeschrieben. Besonders hoch liegt die Energieeinsparung im Leistungsbereich zwischen 0,75 kW und 40 kW, da hier die meisten Betriebsstunden im Jahr anfallen. Gleichzeitig spielt neben der Energieeinsparung auch die Instandhaltung von elektrischen Antrieben eine entscheidende Rolle, da bei plötzlichen Ausfällen hohe Kosten durch Produktionsausfälle oder Reparaturen entstehen können. Um beiden Kriterien gerecht zu werden, wurde ein universell einsetzbares Condition-Monitoring-System entwickelt. Unter Anwendung der integrierten Schwingungsmessung konnten aus unterschiedlichen Belastungs- und Schadensfällen und den daraus ermittelten Kennwerten Vorhersagemodelle und Trendanalysen abgeleitet werden.

Introducción: El diagnóstico rápido y definitivo con identificación del patógeno es fundamental cuando hay una infección periprotésica. La secuenciación de próxima generación permite identificar el ADN en un germen determinado en poco tiempo. Hasta donde sabemos, no hay reportes sobre su empleo para el manejo de la infección periprotésica en Sudamérica. Nuestro objetivo fue demostrar la viabilidad diagnóstica de las muestras obtenidas de una serie de pacientes operados en Buenos Aires, Argentina, y analizadas con la técnica de secuenciación de próxima generación.
Materiales y Métodos: Se analizó a una serie prospectiva de 20 pacientes sometidos a cirugía de revisión séptica y aséptica de cadera desde diciembre de 2019 hasta marzo de 2020. Se obtuvieron muestras intraoperatorias de líquido sinovial, tejido profundo y canal endomedular, que fueron enviadas para su análisis al laboratorio NexGen Microgen.
Resultados: Se seleccionaron 17 pacientes, porque tenían una muestra apta para analizar. Los resultados se recibieron dentro de las 72 h de la cirugía. En un caso, el resultado de la secuenciación de próxima generación informó un germen distinto del identificado en los cultivos posoperatorios de partes blandas, esto permitió corregir la antibioticoterapia. En otro, esta técnica identificó Parabacteroides gordonii en una revisión aséptica, en otro, Morganella morganii, a partir de cultivos negativos en una revisión en un tiempo.
Conclusión: Se demostró la viabilidad diagnóstica con la secuenciación de próxima generación, se pueden obtener resultados de microorganismos patógenos dentro de las 72 h posteriores a la cirugía en pacientes con infección periprotésica y cultivos negativos.

AbstractBackground and aimsMental disorders with high levels of impulsivity such as bulimic spectrum eating disorders (BSED) and gambling disorder (GD) are associated with high risk of suicidal behavior. The aim of the present study was to identify the common and differential vulnerability factors behind suicide attempts in a sample of patients with BSED compared to patients with GD.MethodsA total of 6,077 adults who sought treatment and met criteria either for BSED (n = 2,391) or GD (n = 3,686) were assessed at a specialized hospital unit. Personality traits, psychopathological symptomatology, lifetime history of suicide attempts and socio-demographic variables were evaluated.ResultsThe prevalence of suicide attempts was higher for BSED patients (26.2%) compared to GD patients (7.1%) being anorexia nervosa (Binge/Purge type) and bulimia nervosa the most affected subtypes. In the predictive model, the transdiagnostic vulnerability factors with the highest contribution to the risk of suicidal behavior both in BSED and GD were unemployment, early age of onset of the disorder, worse psychopathological state, and self-transcendence personality trait. However, specific risk factors for suicidal acts were identified in each disorder: longer duration of the disorder, lower education levels and reward dependence were exclusively associated with BSED while female gender, older age, and higher harm avoidance were associated with GD.DiscussionPatients with GD and BSED share certain vulnerability factors although certain factors are exclusive to each disorder.ConclusionsInterventions need to pay special attention to both common and specific vulnerability factors to mitigate the risk of suicidal acts in these disorders.

Published: October 2022

In this study, titanium dioxide (TiO2) and titanium dioxide – activated carbon composite (TiO2–AC) were prepared by sol-gel method for photoelectrochemical (PEC) applications. Characterization of the materials was performed by scanning electron microscope, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and diffuse reflectance spectroscopy. The results show that TiO2 was successfully loaded on activated carbon (AC), producing TiO2–AC with 2.61 eV of bandgap energy, lower than that of TiO2 (3.15 eV). Photoanodes based on TiO2 and TiO2–AC were fabricated and applied to PEC experiments for phenol degradation. In comparison with the TiO2 photoanode, the TiO2–AC one exhibited superior photocatalytic activity, which was indicated by a high current density and effective phenol removal. A mechanism of phenol PEC degradation on the TiO2–AC photoanode was proposed, which includes interaction between protonated phenol and active sites bearing oxygen on the photoanode surface. A kinetic model according to this mechanism was also established and fitted to experimental findings, resulting in rate constants of elementary reactions.

Структура непосредственно обусловленной алкоголем смертности в России в 2011-2021 гг.
Authors: Замятнина Елена Сергеевна 
Published: October 2022

Целями данной работы являются анализ структуры смертности от причин, непосредственно обусловленных алкоголем (т. е. тех причин смерти, в наименовании которых фигурирует слово «алкоголь»), и расчеты потерь ожидаемой продолжительности жизни в России в 2011-2021 гг.
Несмотря на общую тенденцию к снижению непосредственно обусловленной алкоголем смертности, на изученном временном интервале дважды наблюдалось ее повышение. В 2014-2015 гг. оно происходило предположительно вследствие ослабления мер антиалкогольной политики; в 2020 г., вероятно, в связи с социальной напряженностью, вызванной пандемией Covid-19.
Более 70% непосредственно обусловленной алкоголем смертности в 2020-2021 гг. приходилось на трудоспособные возраста. Наиболее высокие показатели непосредственно обусловленной алкоголем смертности в 2011-2021 гг. наблюдались в возрастах 40-65 лет, при этом наибольшее снижение также происходило в этом возрастном интервале.
Структура непосредственно обусловленной алкоголем смертности по причинам смерти на изученном периоде менялась незначительно. Наибольшая доля стабильно приходится на алкогольную кардиомиопатию, которая является ведущей в структуре данных причин и составляет примерно треть от всей непосредственно обусловленной алкоголем смертности. Далее следуют алкогольные отравления и алкогольная болезнь печени. В сумме эти 3 причины смерти составляют более 80% непосредственно обусловленной алкоголем смертности. В структуре женской смертности по сравнению с мужчинами выше доля алкогольной болезни печени, а в структуре мужской по сравнению с женщинами – алкогольных отравлений.
Потери ожидаемой продолжительности в жизни результате непосредственно обусловленной алкоголем смертности составили в 2011-2021 гг. в среднем 0,58 года в год. Важно учитывать, что непосредственно обусловленная алкоголем смертность составляет лишь небольшую часть от всей обусловленной алкоголем смертности.

Authors: Marini Anna , Fuchs Michael 
Published: October 2022

ABSTRACTOn April 2, 2020, extreme metal band Cattle Decapitation released a video for their song “Bring Back the Plague” (2019), whose lyrics invoke a pandemic that wipes out humanity as a means to counter the anthropogenic devastation of Earth. This article explores these lyrics vis‐à‐vis the music video, which tackles the spatiotemporal disruption caused by stay‐at‐home orders at the onset of the COVID‐19 pandemic, condemning anomic behavior and appealing to solidarity and social responsibility.
“See Ya Real Soon”: Destaging Fantasy in COVID‐Era Disney World
Authors: Lantz Vicky Pettersen 
Published: October 2022

ABSTRACTDisney Realism is generally effective at erasing present consciousness, but the specific nature and implications of Covid prevent WDW from discouraging guest awareness of it. The interjection of present real‐world problems/solutions ruptures fantasy. These barriers came in the form of distance, emptiness, and opacity. The social distancing guide markings on the ground, the shielding, the closed spaces, and the open backstage areas all created visible invisible barriers to the Disney park promise of the spectacular, the immersive, and the nostalgic.

Published: October 2022

Background and Objectives: Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. Pe- ripheral blood monocytes cells (PBMCs) may have altered function to some extent in women with endometriosis. Lactoba- cillus acidophilus is a probiotic bacterium within the human bodywith the ability of alleviating many inflammatory diseases. Here, we examined the effect of L. acidophilus on PBMCs of endometriosis patients.
Materials and Methods: In this study, peripheral blood samples were obtained from endometriosis patients (n=11) and non-endometriosis individuals (n=11). After isolation of peripheral blood mononuclear cells with Ficoll, cells were cultured in the presence and absence ofphytohemagglutinin. Also, these cells were co-cultured with 1×106 CFU/ ml of L. acidophilus. IL-6 and IL-1 cytokines were measured by ELISA methodand the two groups were evaluated and compared.
Results: The results showed that in endometriosis patients, the production of pro-inflammatory cytokines, including IL-1 and IL-6, by PBMC was increasedcompared to non-endometriosis subjects, and stimuli such as PHA intensified this elevation. Also, L. acidophilus increased the levels of pro-inflammatorycytokines including IL-1 and IL-6. However, the production of these cytokines decreased due to the modulatory properties of bacterial cells after 48 h.
Conclusion: According to the results of the current study, IL-1 and IL-6 production was significantly increased in PMBCs of endometriosis patientscompared to that of the healthy controls. Also, Lactobacillus acidophilus was considered as an antigenic compound and induced IL-1 and IL-6 production.According to these results, probiotics can be further used for the treatment of endometriosis patients and more investigations are needed to confirm these results.

Background and Objectives: Hepatitis E Virus (HEV) account for acute hepatitis, fulminant liver failure and chronic hep- atitis worldwide. Several high riskgroups including hemodialysis (HD) patients are at risk of HEV infection. Based on con- sequences of HEV infection it is important to determine the serologicaland molecular epidemiology of HEV in HD patients. The aim of this study was to evaluate the frequency of HEV antibodies and HEV RNA in HD patients.
Materials and Methods: The sera of 84 HD patients were collected and tested for anti- HEV IgG and anti IgM antibodies using enzyme-linkedimmunosorbent assay (ELISA) at Golestan hospital in Ahvaz city during October 2014 and November 2014. HEV RNA was tested in HD patients using RT PCR. The prevalence of anti- HEV IgG was evaluated in the age group (52/84) > 50 and (31/84) < 50 years.
Results: Out of 84 patients, 52 (61.9%) were males and 32 (38.1%) females. The mean age of participants was 52 ± 1.57 years. 43/84 (51.19%) casesincluding 26/52 (50%) males and 17/32 (53.1%) females were positive for anti-HEV IgG (p=0.95). Among the 43 cases positive anti-HEV IgG 8 cases including 5 (9.61%) males and 3 (9.37%) females tested posi- tive for anti-HEV IgM (p=0.729) while the HEV RNA was negative in HD patients. Thedistribution of anti- HEV IgG was 62.75% and 33.33% among the age group >50 and <50 respectively (p=0.015).
Conclusion: This study showed high prevalence of anti-HEV IgG antibodies (51.19%) were observed among the HD pa- tients while the HEV RNA testednegative in HD patients. The rate of HEV IgG is significantly higher with increased age. Further investigation require to identify the factors account for high seroprevalence of HEV in Ahvaz HD units.
