Authors: Rajaram Shireen S. , Sayles Harlan R. , Morris Emily , Medcalf Sharon , Sethi Sahil , Keeler Heidi
Published: November 2023

Background:

Human trafficking (HT) is a serious public health issue. Survivors of HT seek medical care. Health care professionals may be inadequately trained to identify and support survivors. This study evaluated improvements in nurses' knowledge after a professional development workshop on HT.

Method:

Pre- and postevaluation surveys assessed nurses' self-reported changes in perceived knowledge of HT and its vulnerability factors, the health impact of HT, strategies for identification and assessment of HT, and response to and follow-up of HT.

Results:

After the workshop, participants showed significant improvement in perceived knowledge of all measures, regardless of hours of previous training and years of practice.

Conclusion:

Perceived knowledge of HT identification and response can be improved through training of nurses, regardless of hours of previous training and years of practice.

Iatrogenic Excessive Clavicle Resection as a Complication of Arthroscopic Distal Clavicle Excision
Authors: Meshram Prashant , Saggar Rachit , Lukasiewicz Piotr , Bervell Joel A. , Weber Stephen C. , McFarland Edward G.
Published: November 2023

Arthroscopic distal clavicle excision (DCE) is a reliable procedure to treat acromioclavicular joint arthritis. Typically, only 1 to 2 cm of distal clavicle should be removed. Resection of too much bone can lead to instability of the joint or lack of support to the shoulder. We describe 2 patients who had excessive clavicular bone removed arthroscopically, leading to irreparable clavicular pain and dysfunction. The 2 female patients, ages 56 and 60 years, presented to our clinic with continued pain after DCE. Both had pain intractable with nonoperative treatment and loss of range of motion of the shoulder. Radiographs revealed a distal clavicle defect of 7.5 cm in 1 patient. The second patient had a 2-cm distal clavicular defect with an adjacent 2-cm clavicle bone fragment between the defect and residual clavicle shaft. Both underwent surgery with subtotal claviculectomy for pain control. During surgery, 1 patient had a subclavian vein requiring vascular repair. After 1 year of follow-up, both patients had reduced but residual pain and restricted range of motion. Only 1 patient could rejoin her preinjury occupation. Neither patient could continue with preinjury recreational sports. Excessive removal of the distal clavicle during DCE can result in continued pain and disability of the shoulder. Methods to visualize the anatomy of the distal clavicle and its articulation to the acromion should be considered when performing this operation arthroscopically. Reoperation to remove subtotal clavicle has good clinical outcomes but may lead to serious complications due to the proximity to major neurovascular structures. [

Published: November 2023

We describe a 36-year-old man with a long-standing diagnosis of ulnar fibrous dysplasia with associated fracture of the ulna. He presented with a growing and increasingly tender forearm mass and was diagnosed with adamantinoma of the ulna, for which he underwent wide resection of the ulnar diaphysis followed by reconstruction with a vascularized fibula autograft. This case serves to emphasize the importance of performing a stepwise workup for the diagnosis of osseous neoplasms even in cases with long-standing diagnoses. [

Authors: Kim Byung-Sung , Jung Ki Jin , Nho Jae-Hwi , Cha Joo Young
Published: November 2023

This study compared the results of endoscopic cubital tunnel release (eCuTR) with those of open cubital tunnel release (oCuTR) for the management of cubital tunnel syndrome (CuTS). In this retrospective study, 35 patients underwent eCuTR or oCuTR. Group I and group II consisted of 16 patients undergoing eCuTR and 19 patients undergoing oCuTR, respectively. Patients were asked to report paresthesia and pain, and electromyography was performed. The Dellon and Bishop classifications were used. The Disabilities of the Arm, Shoulder and Hand (DASH) and visual analog scale (VAS) pain scores were recorded, as well as the key pinch strength and two-point discrimination. The incision length and operation duration were noted. The mean follow-up was 39 months. The mean operating time was longer in the endoscopy group (43 vs 22 minutes). Overall, 34.3% (n=12) of the cases were classified as Dellon grade II and 65.7% (n=23) were classified as Dellon grade III. According to the Bishop score, excellent or good results were obtained for 75% of the patients in the eCuTR group and 78.9% of the patients in the oCuTR group. In the eCuTR and oCuTR groups, all outcome measures improved after surgery: DASH score (preoperative, 37.7 vs 30.7; postoperative, 15.4 vs 20), VAS score (preoperative, 7.8 vs 7.3; postoperative, 4.3 vs 4.1), pinch strength (preoperative, 74 vs 66; postoperative, 93 vs 84), and two-point discrimination (preoperative, 5.6 vs 6.6; postoperative, 4.9 vs 4.5). No significant difference was apparent between the two techniques in outcomes. However, the endoscopic release had a higher reoperation rate and took twice as long to perform despite having a shorter incision. [

Distance measures of picture fuzzy sets and interval-valued picture fuzzy sets with their applications
Authors: Zhu Sijia , Liu Zhe
Published: November 2023

Picture fuzzy sets (PFSs) are a versatile generalization of fuzzy sets and intuitionistic fuzzy sets (IFSs), providing a robust framework for modeling imprecise, uncertain, and inconsistent information across various fields. As an advanced extension of PFSs, interval-valued picture fuzzy sets (IvPFSs) offer superior capabilities for handling incomplete and indeterminate information in various practical applications. Distance measures have always been an important topic in fuzzy sets and their variants. Some existing distance measures for PFSs have shown limitations and may yield counterintuitive results under certain conditions. Furthermore, there are currently few studies on distance measures for IvPFSs. To solve these problems, in this paper we devised a series of novel distance measures between PFSs and IvPFSs inspired by the Hellinger distance. Specifically, all the distance measures were divided into two parts: One considered the positive membership degree, neutral membership degree and negative membership degree, and the other added the refusal membership degree. Moreover, the proposed distance measures met some important properties, including boundedness, non-degeneracy, symmetry, and consistency, but also showed superiority compared to the existing measures, as confirmed through numerical comparisons. Finally, the proposed distance measures were validated in pattern recognition and medical diagnosis applications, indicating that the proposed distance measures can deliver credible, reasonable results, particularly in similar cases.
A cross-modal conditional mechanism based on attention for text-video retrieval
Authors: Du Wanru , Jing Xiaochuan , Zhu Quan , Wang Xiaoyin , Liu Xuan
Published: November 2023

Current research in cross-modal retrieval has primarily focused on aligning the global features of videos and sentences. However, video conveys a much more comprehensive range of information than text. Thus, text-video matching should focus on the similarities between frames containing critical information and text semantics. This paper proposes a cross-modal conditional feature aggregation model based on the attention mechanism. It includes two innovative modules: (1) A cross-modal attentional feature aggregation module, which uses the semantic text features as conditional projections to extract the most relevant features from the video frames. It aggregates these frame features to form global video features. (2) A global-local similarity calculation module calculates similarities at two granularities (video-sentence and frame-word features) to consider both the topic and detail features in the text-video matching process. Our experiments on the four widely used MSR-VTT, LSMDC, MSVD and DiDeMo datasets demonstrate the effectiveness of our model and its superiority over state-of-the-art methods. The results show that the cross-modal attention aggregation approach can effectively capture the primary semantic information of the video. At the same time, the global-local similarity calculation model can accurately match text and video based on topic and detail features.
Origin of Fine-Grained Carbonate Clasts in Cave Sediments
Authors: Zupan Hajna Nadja
Published: November 2023

V vzorcih jamskih klastičnih sedimentov se velikokrat nahajajo velike količine drobnih karbonatnih zrn. Ugotovila sem, da je njihov izvor v mehkih belih conah preperele karbonatne kamnine s sten jamskih rovov. Preperele cone apnenca in dolomita nastajajo na jamskih stenah, kadar nanje deluje selektivna korozija. Nepopolno raztapljanje pripravi karbonatno kamnino na mehansko erozijo in transport njenih trdnih delcev. Kjer je preperela karbonatna kamnina v stiku z vodo, tekočo ali kapljajočo, ta lahko trga njene, s selektivnim raztapljanjem izpostavljene delce. Voda jih odnaša naprej po rovih, ko transportna moč vode pade, se delci usedajo v obliki drobnozrnatega karbonatnega sedimenta velikostnega reda gline, melja in drobnega peska.In many samples of cave clastic sediments the high amount of carbonate clasts is significant. It was found out that their origin is usually in soft white zones of weathered carbonate rock on cave walls. Weathered zones of limestone or dolomite form on the cave walls when the selective corrosive is going on. Incomplete dissolution prepares the carbonate rock for the mechanical erosion and transport of its particles. Where the weathered carbonate rock is in contact with water, both flowing and dripping, it may tear off the particles resulting from selective corrosion. Water carries them along cave passages and when its transporting power decreases, particles accumulate in the form of a fine-grained autochthonous carbonate deposit, in size of clay, silt or fine sand.
Anthron Society (Postojna 1889 - 1911), the Beginning of Organised Speleology in Slovenia
Authors: Kranjc Andrej
Published: November 2023

Sredi 19. stol. sta bila jamarstvo in speleologija na Kranjskem že dobro razvita. Od 1878 se je za naš kras pričel zanimati F. Kraus. 1879 je ustanovil “Verein für Höhlenkunde”, leto kasneje pa “Karst Comité”. Kmalu zatem je želel ustanoviti tudi podružnico tega društva v Postojni. V Planini je bilo že 50 bodočih članov. Poleti 1889 sta domačina z Velikega Otoka pri Postojni odkrila vhod v Otoško jamo, del postojnskega jamskega sistema. Nastal je spor za lastništvo Postojnske jame in kako naj bi delili dohodek. Takoj za tem je bilo ustanovljeno društvo Anthron - odziv na odkritje Otoške jame. Anthron je bilo ekskluzivno društvo z omejenim številom članom, ki so morali živeti v Postojni - večina jih je bila članov postojnske Jamske komisije. »lani Anthrona so odkrili pomembne del Postojnskega jamskega sistema, raziskovali jame v okolici in pomagali takratnim najvidnejšim speleologom Krausu, Martelu, Perku in Puticku. Ko je bilo v Ljubljani ustanovljeno Društvo za raziskavanje podzemskih jam in je Perko objavil namen ustanoviti speleološki inštitut v Postojni, je bilo društvo Anthron ukinjeno. Tako je mogoče dokumentirano podpreti trditev, da se je organizirana speleološka dejavnost v Sloveniji pričela 1889.In the middle of the 19th century caving and speleological activities were well developed in Kranjska (Carniola) already. F. Kraus took an interest in our karst by 1878. In 1879 he founded ˝Verein für Höhlenkunde˝ and a year later ˝Karst Comité˝. Soon afterwards he wanted to set up a branch of ˝Verein˝ at Postojna. In Planina he had 50 future members already. In summer of 1889 some villagers of Veliki Otok near Postojna discovered the entrance to so-called Otoška jama, making a part of Postojnska jama system. The dispute about the ownership and how to share the income of Postojnska jama aroused. And soon afterwards in Postojna the club Anthron was founded - a reaction to this discovery. Anthron was an exclusive club with limited number of members who must live in Postojna - and majority were members of Postojnska jama Cave (Managing) Commission. The Anthron members discovered an important part of Postojnska jama system, explored caves nearby and helped the best known speleologists of that time such as Kraus, Martel, Perko and Putick. When Speleological club was set up in Ljubljana and Perko announced the foundation of Speleological Institute at Postojna, the club Anthron was dismissed. Thus the documents prove that continuous organised speleological activity started in Slovenia in 1889.
Effect of fiber section shape and volume fraction on the mechanical properties of steel-fiber reinforced concretes
Authors: He Wei , Wu Shoujun , Zhang Bo , Liu Yanyu , Luo Yiming , Fu Guo
Published: November 2023

This study presents the preparation of steel-fiber reinforced concretes (SFRCs) using straight navicular fibers with annular-sector-shaped sections and corrugated fiber with rectangular-shaped sections, respectively. The flexural and splitting tensile strengths of both the respective SFRCs increase with increasing fiber volume fraction, whereas their compressive strengths initially increase, then decrease, and then increase again. For the same fiber volume fraction, the mechanical properties of the navicular fiber-reinforced concrete are superior to those of the corrugated fiber-reinforced concretes. The introduction of steel fiber changes the failure mode of the plain concrete during bending from a typical brittle mode to a bimodal ductile failure mode. As compared to the corrugated fiber, the navicular fiber has stronger interface bonding to concrete and a higher friction resistance to fiber sliding and subsequent pullout. Furthermore, navicular fiber has a higher load-bearing capacity, which makes it more favorable for improving the mechanical properties of plain concrete.
A low carbon cement (LC3) as a sustainable material in high strength concrete: green concrete
Authors: Sirangi Bhavani , Prasad M.L.V.
Published: November 2023

Limestone Calcined Clay Cement (LC3) Technology is a low carbon cement that combines limestone, calcined clay, and clinker, aiming to reduce CO2 emissions by 40%-50% during production. In this study, large-scale investigations were conducted to explore LC3 as a potential substitute for conventional cement (CC). Mechanical and durability tests were performed on LC3, comparing results with CC and Pozzolana Cement (PC) concretes. The findings revealed that LC3 concrete exhibited promising early-stage strength similar to CC concrete. However, at 90 days, LC3 showcased a 10% higher strength compared to CC concrete. Additionally, LC3 displayed a remarkable 45% increase in resistance to moisture ingress, indicating improved durability over CC concrete. These results highlight the efficacy of low carbon cement in developing ternary blended cements that offer early strength and enhanced durability, making it a viable eco-friendly alternative in the construction industry.

La fripisation de la Hafsia : une contre-histoire d’un projet de rénovation urbaine à Tunis
Authors: Grüneisl Katharina
Published: November 2023

Le commerce de la fripe est aujourd’hui omniprésent dans le paysage marchand de Tunis. Suite à la révolution tunisienne de 2011, une expansion rapide des marchés aux fripes a ressuscité un discours sur la « fripisation » de la ville, un terme vernaculaire qui souligne le rôle majeur de ce commerce dans les changements de l’espace urbain. Malgré son importance, le commerce de la fripe est souvent considéré comme illégitime par les pouvoirs publics, car sa présence est associée à des appropriations spontanées de l’espace public et à des migrants ruraux pauvres qui restent exclus du marché du travail formel dans la capitale. Partant de ce positionnement contesté du commerce de la fripe à Tunis, cet article étudie les processus d’auto-construction qui ont consolidé le premier espace marchand permanent pour la fripe lors de la réalisation d’un grand projet de rénovation urbaine dans le quartier de la Hafsia, au cœur de la médina de Tunis. Il s’agit ici de dévoiler une « contre-histoire » par rapport aux récits dominants sur la rénovation urbaine en confrontant le discours officiel sur ce grand projet urbain aux récits de vie de migrants ruraux devenus commerçants de la fripe. Une enquête empirique fine des négociations, compromis et coalitions entre commerçants-migrants, autorités urbaines et autres acteurs de la rénovation urbaine éclaire la façon dont le commerce de la fripe a acquis un rôle clé dans la transformation d’un quartier résidentiel en district commercial spécialisé. Cette analyse de la fripisation de la Hafsia décentre ainsi le regard habituel sur les acteurs et processus de la fabrique de la ville, mettant l’accent sur les mécanismes de co-production de l’espace qui ont mené à l’achèvement d’un grand projet urbain, mais qui l’ont profondément remanié, et ce de manière imprévue.
Émergence des nouvelles centralités à Oran en Algérie entre métropolisation et circulation marchande mondialisée
Authors: Otmane Tayeb , Maachou Hadj Mohammed , Yousfi Badreddine
Published: November 2023

Cet article appréhende le phénomène d’émergence des centralités commerciales secondaires dans les villes algériennes à travers l’exemple d’Oran, la seconde ville d’Algérie au rôle métropolitain qui a vu une partie de sa population redéployer vers les nouveaux espaces urbanisés générant une redistribution des activités tertiaires. Celle-ci a fait émerger des lieux d’écoulement du commerce transnational et de consommation globalisée. Cette dynamique commerciale, impulsée par l’orientation du pays vers l’économie de marché et portée par des acteurs privés, transforme les quartiers résidentiels et impose une hiérarchie commerciale qui met le centre-ville, devenu excessivement cher et difficilement accessible, sous concurrence.

Chronic Mania: A Case Series
Authors: Hooda Priyanka , Khobragade Bhupendra , Mahapatra Ananya , Singh Shipra
Published: November 2023

Chronic mania is a known but underexplored entity and still lacks nosological status. Earlier reports of chronic mania have found distinct symptomatology, course, outcome, and treatment challenges. Three cases of chronic mania are presented with challenges in treatment, variable response to drugs and different outcomes along with a synopsis of review of literature in this context. There is a need for longitudinal follow-up studies of patients with diagnosis suggestive of chronic mania for better understanding of treatment response and outcome.

Authors: Singh Shweta , Datta Manjistha , Gupta Pawan Kumar , Batra Saakshi , Gupta Bandna , Garaya Amandeep Singh
Published: November 2023

Background:

The COVID-19 pandemic has posed a unique challenge for all, where numerous coping strategies are being used to adapt to the unprecedented stress. Among them, substance use is one of the most challenging for the youth in a developing country like India.

Aims:

The present study aimed to (1) compare among adolescents, young adults, and middle-aged adults comprehensive coping strategies and substance use, and (2) study various coping strategies as predictors of substance use amid the pandemic.

Methodology:

The sample comprised 1027 participants between 13–60 years of age, further categorized as adolescents (13–18 years), young adults (19–39 years), and middle-aged adults (39–60 years). The assessment was done on the Perceived Stress Scale, Brief COPE Inventory by Carver, and DSM-5 Level 1 Cross-Cutting Symptom Measure. The groups were compared using Kruskal–Wallis and Chi-square. Correlations were calculated using Person’s coefficient, and multiple linear regressions were analyzed.

Results:

The young adults used more substance use; adolescents used more self-blaming, self-distraction, instrumental support, and positive reframing. The male participants resorted to “substance use” while females were more involved with “seeking social support” and “religion.” Perceived stress, coping, age, and gender formed a significant predictor model with substance use, denial, positive reframing, and significant independent predictors of problematic substance use.

Conclusions:

Our study found significant age and gender-related differences in using various coping strategies and substance use. Our study explained substance use through the lens of coping where perceived stress, substance use as coping, denial, and positive reframing were significant independent predictors. Results will help to plan interventions to promote adaptive coping strategies and implement focused interventions in the vulnerable groups.
Prevalence of Depression and Anxiety in Patients with Diabetes Mellitus at a Secondary Level Government Health-Care Facility in Northern India
Authors: Singh Manpreet , Shergill Gagandeep Singh , Bhatt Garima , Gill Zoya
Published: November 2023

Background:

Diabetes is one of the largest global health emergencies of the 21st century. As per the International Diabetes Federation (IDF) in 2020, 463 million people have diabetes in the world and 88 million people in the Southeast Asia region. Seventy-seven million out of 88 million belong to India. The prevalence of diabetes in the population is 8.9%, according to the IDF. There exists a bidirectional association between diabetes and depression/anxiety, with both worsening each other’s prognosis. The prevalence rates of depression could be up to three times higher in patients with type 1 diabetes and twice as high in people with type 2 diabetes, while anxiety disorders are seen in 40% of the patients with type 1 or 2 diabetes mellitus. Although no single cause has been identified for the positive correlation between diabetes and depression and anxiety, it is widely accepted that hypothalamic–pituitary–adrenal dysfunction, pro-inflammatory cytokines, and a host of other epigenetic factors are responsible for the increased prevalence. This study was undertaken to check the prevalence of anxiety and depression in patients with diabetes mellitus attending the outdoor clinics of internal medicine department at a district hospital, Fatehgarh Sahib, Punjab.

Materials and Methods:

Four hundred patients were included in our study. A semi-structured pro forma was used to collect demographic details, and anxiety and depression were screened using the Hamilton Anxiety and Depression Rating Scales, respectively. Data collected were subjected to statistical analysis.

Results:

Fifty-eight percent of the sample population had depression and 27% had anxiety, with a vast majority having mild symptoms. Gender and duration of diabetes were statistically significant variables affecting prevalence and severity, with females having a higher mean scores of depression and anxiety than males and higher scores with greater duration of the illness.

Conclusions:

This study implies need for routine screening of depression and anxiety symptoms in patients with diabetes mellitus and treating them at the earliest.
Prevalence of test anxiety and their related coping strategies in medical students – A cross-sectional study
Authors: Tata Ramya Spandana , Ramya Bommanaboina , Mopidevi Vijayagopal
Published: November 2023

Introduction:

Exam anxiety is characterized by a combination of bodily symptoms, such as overarousal, tension, and somatic symptoms; mental symptoms, such as concern, dread, and fear of failing; and physical symptoms, similar to catastrophizing. According to recent research, test anxiety affects anywhere between 25% and 40% of students. Self-distraction, denial, substance use, behavioral disengagement, emotional support, venting, humor, acceptance, self-blame, religion, active coping, the use of instrumental support, positive reframing, and planning have all been claimed to be successful coping mechanisms.

Aim and Objectives:

This study aimed to assess the test anxiety levels and related coping strategies in medical students.

Materials and Methods:

A total of 106 medical students of a tertiary care teaching hospital were included between September 2022 and January 2023. The students who consented to participate in the study were asked to complete the self-administered questionnaire consisting of parts on sociodemographic profile, Westside Test Anxiety Scale, and Brief Coping Orientation to Problems Experienced Scale.

Results:

Males had 38.1%, 35.7%, and 26.7% of average, moderate, and high levels of test anxiety and females reported of 43.8%, 34.4%, and 21.9%, respectively.

Conclusion:

Academic factors are greater perceived cause of anxiety in medical students. Interventions must be developed and implemented to target particular stressors to reduce the burden and anxiety on students from the 1st year itself. Early screening and interventions of test anxiety among medical students were warranted.
Renal Function Improvement after Aortic Valve Replacement in a Patient with Chronic Kidney Disease – A Case Report
Authors: Kumar Sathish , Sayyed Azhar Salimahmed , Roy Kiranmoy , Parvathy Gauri
Published: November 2023

Inadequate peripheral perfusion due to cardiac diseases can worsen renal function in patients with chronic kidney disease (CKD). Due to the nature of the simultaneous cardiac and renal disease, it is often difficult to determine which is the primary cause, and hence many surgeons hesitate to operate on patients with end-stage kidney disease. However, when the primary cause is cardiac related, renal function can improve after successful cardiac surgery. Here, we describe a 55-year-old female patient with CKD Stage 5 who was on maintenance hemodialysis with severe aortic stenosis (AS) and underwent surgical aortic valve replacement and recovered from dialysis-dependent kidney disease. Drastic improvement in renal function after cardiac surgery can occur even in patients with CKD due to improved renal perfusion, especially in cases of AS. Therefore, diagnosing the primary cause of renal dysfunction is essential.
Empirical Study on Influencing Factors of Rural Environmental Behavior in Informatization
Authors: Cai Jianming , Ling Hong , Yang Chao , Gu Jianfeng
Published: November 2023

INTRODUCTION: With the advent of the information technology era, rural areas face new environmental protection challenges and opportunities. The rapid development of information technology provides new possibilities for changes in rural ecological behavior. However, understanding the influencing factors of rural environmental behavior in the context of information technology remains an important research topic.
OBJECTIVES: This study aims to reveal the influencing factors of rural environmental behavior in the context of information technology to help governments and policymakers develop effective environmental protection strategies. Specifically, the researchers will focus on the extent to which factors such as education level, ecological awareness, economic status, and social participation influence the environmental behavior of rural residents.
METHODS: A questionnaire survey was used in this study, and residents of a particular rural area were selected as the research subjects. A questionnaire containing questions on education level, environmental awareness, economic status, social participation, and environmental behavior was designed, and a large amount of data was collected through random sampling. Statistical analysis methods, such as regression and correlation analyses, were used to process and interpret the data.
RESULTS: The study's results showed that the education level significantly affected the environmental behavior of rural residents. Residents with higher levels of education were more inclined to take positive ecological protection actions such as waste separation and energy conservation. In addition, environmental awareness was also found to be closely related to environmental behavior, with residents with higher ecological awareness being more concerned about environmental protection and taking action accordingly. Economic status and social participation affected rural residents' environmental behavior to a certain extent but to a lesser extent than education level and ecological awareness.
CONCLUSION: Rural environmental behavior in the context of informatization is affected by a combination of factors. To promote rural ecological protection, the government should strengthen investment in education and improve rural residents' education level and environmental awareness. In addition, social organizations and public participation should also be supported to encourage rural residents to actively participate in environmental protection actions. These measures will help to promote a change in ecological behavior in rural areas and achieve the goal of sustainable development.
Arf invariants of codimension one in a Wall group of the dihedral group
Authors: Akhmet'ev Petr Mikhailovich , Muranov Yury Vladimirovich
Published: November 2023

An element $x$ is specified in the Wall group $L_3(D_3)$ of the dihedral group of order $8$ with trivial orientation character, such that $x$ is an element of the third type in the sense of Kharshiladze with respect to any system of one-sided submanifolds of codimension $1$ for which the splitting obstruction group along the first submanifold is isomorphic to $LN_1(\mathbb Z/2\oplus \mathbb Z/2\to D_3)$. The element $x$ is not realisable as an obstruction to surgery on a closed $\mathrm{PL}$-manifold. It is also proved that the unique nontrivial element of the group $LN_3(\mathbb Z/2\oplus \mathbb Z/2\to D_3^-)$ can be detected using the Hasse-Witt $Wh_2$-torsion.

Published: November 2023

Questions relating to theorems of Levinson-Sjöberg-Wolf type in complex and harmonic analysis are explored. The well-known Dyn'kin problem of effective estimation of the growth majorant of an analytic function in a neighbourhood of its set of singularities is discussed, together with the problem, dual to it in certain sense, on the rate of convergence to zero of the extremal function in a nonquasianalytic Carleman class in a neighbourhood of a point at which all the derivatives of functions in this class vanish.
The first problem was solved by Matsaev and Sodin. Here the second Dyn'kin problem, going back to Bang, is fully solved. As an application, a sharp asymptotic estimate is given for the distance between the imaginary exponentials and the algebraic polynomials in a weighted space of continuous functions on the real line.

О линейных уравнениях динамики
Authors: Kozlov Valery Vasil'evich
Published: November 2023

Рассматриваются линейные автономные системы дифференциальных уравнений второго порядка, не содержащие первых производных независимых переменных. Такие системы часто встречаются в классической механике. Особый интерес представляют случаи, когда внешние силы не потенциальны. Важный частный случай - уравнения неголономной механики, линеаризованные в окрестности положений равновесия второго рода. Показано, что линейные системы такого вида всегда можно представить в виде уравнений Лагранжа и Гамильтона, причем эти уравнения вполне интегрируемы: они допускают полные наборы независимых инволютивных интегралов, которые квадратичны или линейны по скоростям. Линейные интегралы являются нeтеровыми: их наличие связано с нетривиальными группами симметрий.
Нелинейные эффекты и заплеск береговых волн, порожденных бильярдами с полужесткими стенками, в рамках теории мелкой воды

Под береговыми волнами понимаются периодические или близкие к периодическим по времени гравитационные волны на воде в бассейне глубины $D(x)$, $x=(x_1,x_2)$, локализованные в окрестности береговой линии $\Gamma ^0=\{D(x)=0\}$. В работе для двух конкретных примеров строятся отвечающие береговым волнам асимптотические решения системы нелинейных уравнений мелкой воды в виде параметрически заданных функций, соответствующих асимптотическим решениям линеаризованной системы, которые, в свою очередь, связаны с асимптотическими собственными функциями оператора $-\nabla \cdot (gD(x)\nabla )$, порождаемыми "бильярдами с полужесткими стенками".

Исследуются автомодельные решения задачи Римана в области неединственности для слабо анизотропных упругих сред с отрицательным параметром нелинейности. Показано, что все разрывы, входящие в состав решений в области неединственности, обладают стационарной структурой. Показано, что в области неединственности возможно построение двух типов автомодельных решений.
Волновые структуры в течениях идеального газа с внешним источником энергии
Authors: Chesnokov Aleksandr Aleksandrovich
Published: November 2023

Рассматривается распространение плоских волн в идеальном газе при наличии внешних источников притока и диссипации энергии. С использованием критерия Уизема получены условия, при которых малые возмущения постоянного решения трансформируются в нелинейные квазипериодические волновые пакеты конечной амплитуды, движущиеся в противоположных направлениях. Показано, что эти волновые пакеты аналогичны по структуре катящимся волнам в открытых наклонных каналах. Выполнены численные расчеты развития автоколебаний и нелинейного взаимодействия волн. Установлено, что при малом гармоническом возмущении начального состояния равновесия могут развиться два вида волновых структур: катящиеся волны и периодические двухпиковые стоячие волны.

Published: November 2023

Уравнения жидкости второго порядка описывают движения релаксирующих жидкостей, таких как водные растворы полимеров. Вопросы существования и единственности решений начально-краевых задач для этих уравнений изучались в работах Д. Чоранеску и В. Жиро, К. Ле Ру и А. Тани, Дж.П. Галди и других. Эти публикации не содержат информации о качественных свойствах решений указанных уравнений. Такую информацию можно получить, анализируя их точные решения, чему и посвящена данная работа. В ней изучены слоистые течения, модельная задача со свободной границей, построен аналог решения Т. Кармана, которое описывает стационарное движение жидкости второго порядка в полупространстве, индуцированное вращением ограничивающей ее плоскости, приведено обобщение решения В.А. Стеклова задачи о нестационарных винтовых течениях ньютоновской жидкости на случай жидкости второго порядка.

Статья содержит обзор численных исследований специального класса ловушек для удержания плазмы магнитным полем, в которых токонесущие проводники погружены в плазменный объем. Следуя А.И. Морозову, эти ловушки называют галатеями. Исследования изложены на примере цилиндра с двумя параллельными оси проводниками - распрямленного аналога тороидальной ловушки "Галатея-пояс". Математическая модель равновесия основана на краевой задаче с двумерным эллиптическим уравнением Грэда-Шафранова, которая решается численно. Основной интерес представляют различные подходы к исследованию устойчивости магнитоплазменных конфигураций в ловушке и ее зависимость от геометрии и параметров задачи. Рассмотрена устойчивость в линейном приближении одномерных конфигураций, окружающих один проводник, и двумерных конфигураций в ловушке "Галатея-пояс". Основным результатом расчетов в различных постановках задач является ограничение сверху отношения характерных значений газового и магнитного давлений, обеспечивающего устойчивость. В статье кратко изложены опубликованные в последние годы основные результаты и приведены новые результаты, полученные в настоящее время.
Линейное и нелинейное развитие изгибных возмущений в трубе с переменными упругими свойствами с протекающей внутри жидкостью
Authors: Abdul'manov Kirill Eduardovich , Vedeneev Vasily Vladimirovich
Published: November 2023

Рассматриваются изгибные колебания трубы, заполненной движущейся жидкостью, лежащей на упругом основании с неоднородным коэффициентом упругости. Ранее А.Г. Куликовским было аналитически показано, что возможно такое распределение параметров упругости, при котором в каждой точке система будет либо локально устойчивой, либо неустойчивой конвективно. При этом, несмотря на отсутствие локальной абсолютной неустойчивости, существует глобальная растущая мода, образование которой связано с наличием точек внутреннего отражения волн. В настоящей работе проводится численное моделирование развития начального возмущения в такой системе. В линейной постановке продемонстрировано, как происходит преобразование возмущения в растущую собственную моду после серии отражений и прохождений через участок локальной неустойчивости. В нелинейной постановке, где учитывается нелинейное натяжение трубы в рамках модели Кармана, показано, что рост возмущения ограничен, при этом колебания приобретают квазихаотический характер, но не покидают зоны, ограниченной точками внутреннего отражения, определяемыми линеаризованной задачей.
Тополого-аналитический метод доказательства теорем об усреднении на бесконечном интервале времени в вырожденном случае
Authors: Polekhin Ivan Yur'evich
Published: November 2023

Приводится тополого-аналитический метод доказательства некоторых утверждений из классического метода усреднения Н.Н. Боголюбова на бесконечном интервале времени. Суть метода заключается в комбинировании топологических методов доказательства существования периодических решений, примененных к усредненной системе, с теоремой Боголюбова об усреднении на конечном интервале времени. Предлагаемый подход позволяет отказаться от условия невырожденности матрицы Якоби из классических теорем метода усреднения.
Аналитические свойства решений уравнения внутренних гравитационных волн с течениями для критических режимов волновой генерации
Authors: Bulatov Vitalii Vasil'evich
Published: November 2023

Рассмотрены вопросы, связанные с постановкой задач описания динамики линейных внутренних гравитационных волн в стратифицированных средах с горизонтальными сдвиговыми течениями при критических режимах волновой генерации. В плоской постановке обсуждены модельные физические постановки задач, в которых могут возникать критические уровни. Изучены аналитические свойства решений вблизи критических уровней. Рассмотрена постановка задачи о потоке стратифицированной среды, набегающем на препятствие, за которым могут возникать уходящие волны, при этом особенность на критическом уровне формируется вдали от препятствия. Построены асимптотики решений вблизи критического уровня, которые выражаются через неполную гамма-функцию.
The Professional Status of Adult Educators
Authors: Piliri Andri , Gravani Maria N.
Published: November 2023

The paper reports findings from a research study carried out with adult education professionals working in Adult Education Centres (AECs) in Cyprus. It aims to explore how they experience their professional status in the programme as well as identify barriers that hinder their professionalisation and particular barriers caused in the course of the COVID-19 pandemic. The study harnesses qualitative methodology and adopts a bottom-up approach as it gives voice to adult educators and makes meaning out of their working experiences. It makes suggestions for the improvement of their professional status based on the idea of humanisation, a multifaceted process in which both the state and adult educators themselves should become communions.

Published: November 2023

There are restricted movements in Katigraha mainly occurring at L4 – L5 Lumbar vertebra. Restricted movements
along with pain are a common complaint of Katigraha patient attending in OPD. It is mainly due to improper postural habits, unhealthy dietary patterns and improper daily routine. It is neither a serious disorder nor a life threatening one but at the same time can be crippling by grossly disturbing the individual’s day-to-day lifestyle. In matra basti, medicated oil is inserted to the rectum (Pakwashaya) from anus with the help of rubber catheter (Enema
pot). A total of 30 patients were selected complaining of pain, stiffness, restricted movements in the lumbar region. Matra basti with Swadamshtradi taila in dose of 60 ml for 7 days were given to the selected patients. It was
observed that Swadamshtradi taila matra basti was highly significant for reducing pain, restricted movements and
stiffness of Katigraha patients.
