“Una puerta se abrió”. Videntes, elegidas y médiums en los escenarios de la religiosidad contemporánea (Salto, Uruguay y Girona, España)
Authors: Vigna Sibila
Published: March 2022

Espíritus de difuntos, seres de luz, entidades malignas y mensajes celestiales no han perdido vigencia en ámbitos contemporáneos de creencias, en los que ciertas experiencias de los sentidos se interpretan como contactos con lo sobrenatural y lo extraordinario. Las personas protagonistas de este artículo describen persistencia y continuidad en la percepción de esta clase de estímulos a lo largo de la vida, asociados con itinerarios espirituales que les identifican como videntes, elegidas o médiums con mandatos particulares de origen divino. En diálogo con aportaciones teóricas y etnografías de referencia sobre patrones y contextos de visiones y mediumnidad, el presente artículo explora la integración de la experiencia extraordinaria en la vida cotidiana, las ideas culturales relacionadas, y sus articulaciones con entornos sociales y escenarios religiosos, a partir del trabajo de campo realizado en Salto (Uruguay) y en Girona (España). Los modelos explorados se corresponderían con una categoría de praxis creyente, fundamentada en la comunicación sin intermediarios con entidades espirituales, el lugar del cuerpo en la vivencia de lo sagrado, los conocimientos esotéricos y las configuraciones de discursos religiosos a medida.
Diversidad religiosa, políticas públicas y gentrificación en París y Barcelona
Authors: Albert Blanco Víctor
Published: March 2022

Este artículo analiza la interrelación entre la regulación de las manifestaciones religiosas y las transformaciones urbanas en las ciudades europeas contemporáneas. Concretamente, pone el foco en dos barrios de París y Barcelona que han experimentado, a lo largo de los últimos años, reformas urbanas importantes y un ingente proceso de gentrificación. A partir del trabajo de campo cualitativo llevado a cabo en esos dos barrios, el artículo detalla unos actores y unas estrategias de regulación de las expresiones religiosas que son coherentes con estas transformaciones, participando así en la formulación de proyectos morales sobre un espacio público concebido como diverso y multicultural a la vez que ordenado y pacificado. El artículo contribuye y complementa la literatura sobre la gobernanza de la diversidad religiosa en Europa, al mismo tiempo que señala la relevancia de los contextos urbanos particulares y de los procesos de cambio y disputa que los atraviesan
Proyectos morales y nuevas subjetividades religiosas en el espacio público. A modo de presentación
Authors: Cornejo-Valle Monica , Griera Mar
Published: March 2022

Este texto presenta el número monográfico “Proyectos morales y nuevas subjetividades religiosas en el espacio público”. En este monográfico queremos abordar la exploración de las nuevas subjetividades religiosas en el espacio público, enmarcándolo especialmente en lo que el sociólogo José Casanova identificó como el proceso de desprivatización de la religión. La visibilidad actual de viejas y nuevas subjetividades religiosas socava la apariencia secularidad y favorece, también, el crecimiento de formas de expresión, performativas, de la religión en el espacio urbano. No es un fenómeno uniforme ni homogéneo. Nos referimos a casos como los siguientes: la organización de procesiones sij o hindús por parte de las diásporas en la mayoría de ciudades del mundo, la organización de marchas católicas anti-aborto en fechas señaladas, la organización de meditaciones públicas para la paz de forma simultánea en distintas ciudades, también las iniciativas públicas para apostatar, la organización de grandes eventos evangélicos en espacios públicos o la celebración de encuentros multitudinarios a raíz de la visita de líderes religiosos como el Papa de Roma o el Dalai Lama en determinadas ciudades. Tras el texto de Judit Bokster Liwerant en la sección Fundamentales, el número cuenta con las contribuciones de Víctor Albert Blanco, Mónica Cornejo-Valle y Maribel Blázquez-Rodríguez, Joseba García Martín, Carolina Esteso y Borja Martín-Andino, Miquel Fernández González, y Sibila Vigna. A esto se suman, en la sección Papeles Críticos, los trabajos de José Barrera Blanco, Rosa Martínez-Cuadros, y Josep Roca Guerrero.
Célula K0-UFBA, uma proposta para obtenção do parâmetro K0 em laboratório
Authors: Baptista Jorge da Silva João Carlos
Published: March 2022

O presente trabalho apresenta a célula K0-UFBa, onde é mostrado um dispositivo eficiente para a determinação do coeficiente de empuxo no repouso de solos a partir de amostras indeformadas. A célula K0-UFBa foi desenvolvida e licenciada no LabGeo da Escola Politécnica da Universidade Federal da Bahia (UFBa), Brasil. Seus principais componentes e detalhes de montagem são mostrados. O desenvolvimento do equipamento baseou-se nos ensaios de odômetro, porém com confinamento lateral de água, que por ser incompressível, não permite deformação neste sentido, mantendo a condição de K0. A fim de avaliar os resultados da célula K0 em amostras indeformadas obtidas de dois poços escavados em solo residual, esses resultados foram comparados com os ensaios DMT, que foram feitos próximo aos poços. Os resultados mostraram comportamento semelhante ao longo da profundidade em ambas às áreas de ensaio quando comparados com os resultados da célula K0 e ensaios de campo (DMT). A pequena variação dos valores deve-se principalmente à heterogeneidade do solo residual, associada a fatores como erosão superficial, cimentação devido à presença de óxidos e histórico de tensões originadas da rocha mãe.

A systematic review on urolithiasis in small ruminants according to nutrition-dependent prevalence and outcome after surgery
Authors: Sickinger Marlene , Windhorst Anita
Published: March 2022

Background and Aim: Obstructive urolithiasis is a common disease in small ruminants with fatal outcomes if left untreated. Many methods have been established; however, long-term success rates remain unsatisfactory. Four bibliographic databases (PubMed, HeBis, Medline (OvidSP), and Web of Science) were searched to evaluate the prevalence of urolithiasis in small ruminants and long-term outcomes after surgery using a systematic review. The study aimed to give evidence-based data concerning prevalence and success rates after surgery.

Materials and Methods: The analysis included 24 (total 239) peer-reviewed journal articles dealing with the prevalence of urolithiasis and 16 (total 39) concerning long-term outcomes after surgery. Literature was included if it referred to species, language, availability, and relevant statements to the specific questions, including the presence of control groups. Heterogeneity tests included χ2, Ι2, and τ2, respectively. A 95% confidence interval was determined, and effects were estimated using the fixed effect model. Due to a feeding-associated bias, prevalence analysis was conducted for a sorghum-based and a corn-based feeding resulting in a weighted prevalence of 62% and 17%, respectively. Analysis of long-term outcomes after surgical interventions revealed long-term success rates of 15-77% after ultrasonographic tube cystotomy and marsupialization of the urinary bladder, respectively.

Results: The prevalence of urolithiasis is strongly associated with feeding and may be calculated as 17% in corn-based rations and 62% in sorghum-based rations. Surgical interventions result in guarded to moderate long-term success rates of 15-66%. Urethral stoma and marsupialization of the bladder provide acceptable long-term success rates with 71-77% but are rather salvage techniques than accepted surgical methods, especially when used in companion animals.

Conclusion: The development of urolithiasis is mainly influenced by nutrition. Effective prophylaxis of this disease should, therefore, always include advisory service for the owners. Existing surgical techniques should be critically re-evaluated concerning their long-term success rates.

Published: March 2022

Objective: A post hoc subgroup analysis of prospectively collected data from a randomized controlled trial was conducted to identify risk factors related to poor outcomes in patients who underwent minimally invasive discectomy.Methods: Patients were divided into satisfied and dissatisfied subgroups based on Oswestry Disability Index (ODI), visual analogue scale (VAS) back pain score (VAS-back) and leg pain score (VAS-leg) at short-term and midterm follow-up according to the patient acceptable symptom state threshold. Demographic characteristics, radiographic parameters, and clinical outcomes between the satisfied and dissatisfied subgroups were compared using univariate and multivariate analysis.Results: A total of 222 patients (92.1%) completed 2-year follow-up, and the postoperative ODI, VAS-back, and VAS-leg were significantly improved after surgery as compared to preoperatively. Multivariate analysis indicated older age (p = 0.026), lateral recess stenosis (p = 0.046), and lower baseline ODI (p = 0.027) were related to poor short-term functional improvement. Higher baseline VAS-back (p = 0.048) was associated with poor short-term relief of back pain, while absence of decreased sensation (p = 0.019) and far-lateral disc herniation (p = 0.004) were associated with poorer short-term relief of leg pain. Lumbar facet joint osteoarthritis was identified as a risk factor for poor functional improvement (p = 0.003) and relief of back pain (p = 0.031). Disc protrusion (p = 0.036) predicted poorer relief of back pain at midterm follow-up.Conclusion: In this study, several factors were identified to be predictive of poor surgical outcomes following minimally invasive discectomy.

Objective: Spinal cord tumors constitute a small part of spinal surgery owing to their rarity. This retrospective study describes their current management.Methods: Forty-eight patients were treated for an intramedullary tumor between 2014 and 2020 at a single institution. Patients’ files were retrospectively studied. We detailed clinical status according to neurological deficit and ambulatory ability using the modified McCormick Scale, radiological features like number of levels, associated syringomyelia, surgical technique with or without intraoperative electrophysiological monitoring, pathological findings, and postoperative outcome.Results: The median age of this population was 43 years, including 5 patients under 18 years. The median delay before first neurosurgical contact was 3 months after the first clinical complaint. Treatment was gross total resection in 43.8%, subtotal resection in 50.0%, and biopsy in 6.2%. A laminectomy was performed for all the patients except 2 operated using the laminoplasty technique. Pathological findings were ependymoma in 43.8%, hemangioblastoma in 20.8%, and pilocytic astrocytoma in 10.4%. Six patients were reoperated for a tumor recurrence less than 2 years after the first surgical resection. One patient was reoperated for a postoperative cervical kyphosis.Conclusion: Intramedullary tumors are still a challenging disease and they are treated by various surgical techniques. They must be managed in a specialized center including a trained surgical, radiological, electrophysiological, and pathological team. Arthrodesis must be discussed before performing extensive laminectomy to avoid postoperative kyphosis.

Bleeding in spine surgery is a common occurrence but when bleeding is uncontrolled the consequences can be severe due to the potential for spinal cord compression and damage to the central nervous system. There are many factors that influence bleeding during spine surgery including patient factors and those related to the type of surgery and the surgical approach to bleeding. There are a range of methods that can be employed to both reduce the risk of bleeding and achieve hemostasis, one of which is the adjunct use of hemostatic agents. Hemostatic agents are available in a variety of forms and materials and with considerable variation in cost, but specific evidence to support their use in spine surgery is sparse. A literature review was conducted to identify the pre-, peri-, and postsurgical considerations around bleeding in spine surgery. The review generated a set of recommendations that were discussed and ratified by a wider expert group of spine surgeons. The results are intended to provide a practical guide to the selection of hemostats for specific bleeding situations that may be encountered in spine surgery.

INTRODUCTION:

To determine whether percutaneous tibial nerve stimulation (PTNS) is superior to sham stimulation for the treatment of fecal incontinence (FI) in women refractory to first-line treatments.

METHODS:

Women aged 18 years or older with ≥3 months of moderate-to-severe FI that persisted after a 4-week run-in phase were randomized 2:1 (PTNS:sham stimulation) to 12 weekly 30-minute sessions in this multicenter, single-masked, controlled superiority trial. The primary outcome was change from baseline FI severity measured by St. Mark score after 12 weeks of treatment (range 0–24; minimal important difference, 3–5 points). The secondary outcomes included electronic bowel diary events and quality of life. The groups were compared using an adjusted general linear mixed model.

RESULTS:

Of 199 women who entered the run-in period, 166 (of 170 eligible) were randomized, (111 in PTNS group and 55 in sham group); the mean (SD) age was 63.6 (11.6) years; baseline St. Mark score was 17.4 (2.7); and recording was 6.6 (5.5) FI episodes per week. There was no difference in improvement from baseline in St. Mark scores in the PTNS group when compared with the sham group (−5.3 vs −3.9 points, adjusted difference [95% confidence interval] −1.3 [−2.8 to 0.2]). The groups did not differ in reduction in weekly FI episodes (−2.1 vs −1.9 episodes, adjusted difference [95% confidence interval] −0.26 [−1.85 to 1.33]). Condition-specific quality of life measures did not indicate a benefit of PTNS over sham stimulation. Serious adverse events occurred in 4% of each group.

DISCUSSION:

Although symptom reduction after 12 weeks of PTNS met a threshold of clinical importance, it did not differ from sham stimulation. These data do not support the use of PTNS as conducted for the treatment of FI in women.

INTRODUCTION:

There is currently little knowledge on factors associated with the relapse of Crohn's disease (CD) in children. The aims of this study were to describe the risk factors associated with relapse in pediatric CD and the changes in the relapse rate over the past decade.

METHODS:

Patients younger than 18 years and diagnosed between 2009 and 2019 were included in this retrospective cohort study. Clinical, endoscopic, histological, and laboratory data, as well as induction and maintenance treatments, were collected from the medical records. Survival analyses and Cox regression models were used to assess the impact of these risk factors on relapse.

RESULTS:

Six hundred thirty-nine patients were included. There was a decrease in the clinical relapse rate over the past decade: 70.9% of the patients diagnosed between 2009 and 2014 relapsed as compared with 49.1% of the patients diagnosed between 2015 and 2019 (P < 0.0001). The following variables were associated with clinical relapse: female sex (adjusted hazard ratio [aHR] = 1.52, P = 0.0007), exposure to oral 5-ASA (aHR = 1.44, P = 0.04), use of immunomodulatory agents compared with tumor necrosis factor-alpha inhibitors (methotrexate aHR = 1.73, P = 0.003; thiopurines aHR = 1.63, P = 0.002), presence of granulomas (aHR = 1.34, P = 0.02) and increased eosinophils on intestinal biopsies (aHR = 1.36, P = 0.02), high levels of C-reactive protein (aHR = 1.01, P < 0.0001) and fecal calprotectin (aHR = 1.08, P < 0.0001), and low serum infliximab levels (aHR = 2.32, P = 0.001).

DISCUSSION:

Relapse of pediatric CD has decreased in the past decade. The risk of relapse is significantly associated with clinical, endoscopic, histological, and laboratory variables and treatment strategies.

Effective Communication Strategies and Tools for Improving Treatment Outcomes in Patients With Chronic Idiopathic Constipation and Irritable Bowel Syndrome With Constipation
Authors: Kassebaum-Ladewski Amy , Poppers David M. , Brenner Darren M.
Published: March 2022

Patients with chronic idiopathic constipation and irritable bowel syndrome with constipation experience an array of gastrointestinal symptoms. Given the subjective nature of these disorders, patient self-reporting is critical to diagnosis and monitoring response to therapy. Unfortunately, many patients are reluctant to discuss bowel symptoms with their healthcare providers. Differences in sex, health literacy, and age can influence symptom reporting. Negative patient–physician relationships and dissatisfaction with care lead patients to seek alternative treatments, switch healthcare providers, or discontinue care. Thus, adopting a patient-centered communication style can help create a shared understanding of patients' symptoms, achieve accurate symptom reporting, expedite diagnosis, and facilitate appropriate treatment plans. Currently, there are multiple symptom and quality-of-life scales available to assist healthcare providers in this endeavor. These scales also allow for the monitoring of constipation-related symptoms and symptom severity. When using patient self-assessments to measure treatment responses, scale selection may depend on the number of symptoms being assessed, the duration and frequency of assessments, and patients' comprehension and language skills.
Real-World Treatment Strategies to Improve Outcomes in Patients With Chronic Idiopathic Constipation and Irritable Bowel Syndrome With Constipation

Published: March 2022

Chronic idiopathic constipation and irritable bowel syndrome with constipation are complex, overlapping conditions. Although multiple guidelines have informed healthcare providers on appropriate treatment options for patients with chronic idiopathic constipation and irritable bowel syndrome with constipation, little direction is offered on treatment selection. First-line treatment options usually include fiber and over-the-counter osmotic laxatives; however, these are insufficient for many individuals. When these options fail, prescription secretagogues (plecanatide, linaclotide, lubiprostone, and tenapanor [pending commercial availability]), or serotonergic agents (prucalopride and tegaserod) are generally preferred. Individuals experiencing concurrent abdominal pain and/or bloating may experience greater overall improvements from prescription therapies because these agents have been proven to reduce concurrent abdominal and bowel symptoms. Should initial prescription treatments fail, retrying past treatment options (if not adequately trialed initially), combining agents from alternative classes, or use of adjunctive therapies may be considered. Given the broad spectrum of available agents, therapy should be tailored by mutual decision-making between the patient and practitioner. Overall, patients need to be actively monitored and managed to maximize clinical outcomes.

Asymmetric Effects of Private Debt on Income Growth
Authors: Liaqat Zara , Ahmed Muhammad Farid
Published: March 2022

This paper uses a panel vector autoregressive model to study the differential effects of components of private debt on income growth for a large panel of countries. While household debt growth in a given period generally has a positive impact on income, this effect is much stronger for countries with relatively lower levels of income and household debt-to-GDP ratios. On the other hand, the responsiveness of income growth to an increase in corporate debt varies across countries, with a consistently negative impact in richer and/or more heavily indebted countries. A simple extension of our framework suggests the roles of investment and consumption spending in explaining the varying effects of household and corporate debt on growth. We carry out several exercises to illustrate the robustness of our results.

Published: March 2022

The photodynamic treatment for antimicrobial applications or anticancer therapy relies on reactive oxygen species generated by photosensitizing molecules after absorption of visible or near-infrared light. If the photosensitizing molecule is in close vicinity of the microorganism or the malignant cell, a photocytotoxic action is exerted. Therefore, the effectiveness of photosensitizing compounds strongly depends on their capability to target microbial or cancer-specific proteins. In this study, we report on the preparation and preliminary characterization of human recombinant myoglobin fused to the vasoactive intestinal peptide to target vasoactive intestinal peptide receptor (VPAC) receptors. Fe-protoporphyrin IX was replaced by the photosensitizing compound Zn-protoporphyrin IX. Taking advantage of the fluorescence emission by Zn-protoporphyrin IX, we show that the construct can bind prostate cancer cells where the VPAC receptors are expressed.
Tribological properties and characterization of borided Co–Mg alloys
Authors: Yıldız Ismail
Published: March 2022

In this study, tribological properties and characterization of borided Co–Mg alloys were investigated. Cobalt–magnesium (CM) alloys with 97% Co–3% Mg composition were borided at temperatures of 850–900°C and for 1.5–4.5 h with solid boriding. The properties of the resulting boride layers were measured and determined by microhardness, scanning electron microscopy (SEM), X-ray diffraction (XRD), density, and surface roughness testers. XRD analysis results after boriding found CoB, Co2B, and Co phases. Depending on the boriding time and temperature, the thickness of the boride layer for the CM alloy varied from 51 to 138 µm. The boride layer had a hardness varying between 1,674 and 1,956 HV0.05 for the CM alloy, while the Vickers hardness value of untreated Cobalt was 52 HV0.05. The wear tests were carried out in a ball-disc arrangement under a dry friction condition at room temperature with an applied load of 10 N and with a sliding speed of 0.3 m/s at a sliding distance of 250 m. It was observed that the wear rate of borided and unborided CM alloy ranged from 25.89 × 10−5 to 94.95 × 10−5 mm3/N m. As a consequence of the findings, the author reported that boriding CM alloys in the given conditions can make a difference for different application areas.

Published: March 2022

In order to understand the corrosion behavior of high-velocity oxygen-fuel (HVOF) TiAlNb coatings in molten Zn-0.2 wt.% Al, the different kinds of TiAlNb coating were deposited on 316L stainless steel substrate and the corrosion tests in molten zinc were carried out. The coating morphologies, phase composition, and characteristics of HVOF TiAlNb coatings at different stages of immersion time were studied by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectrometry (EDX). The results indicated that the HVOF sprayed TiAlNb intermetallic compound coatings have excellent corrosion resistance to molten zinc. The corrosion type of the HVOF TiAlNb coatings in molten Zn-0.2 wt.% Al is pitting corrosion and crack corrosion. In the whole corrosion stage of molten Zn-0.2 wt.% Al, the corrosion time has no effect on the phase compositions of the HVOF TiAlNb coatings.

Published: March 2022

We provide qualitative bounds on the area and topology of separating constant mean curvature (CMC) surfaces of bounded (Morse) index. We also develop a suitable bubble-compactness theory for embedded CMC hypersurfaces with bounded index and area inside closed Riemannian manifolds in low dimensions. In particular, we show that convergence always occurs with multiplicity one, which implies that the minimal blow-ups (bubbles) are all catenoids.

Published: March 2022

2-Pyridone is considered as one of the most famous efficient pharmaceutical compounds. Many approaches were discovered to synthesize 2-pyridone. In this present research, chloroacetylation of benzylamine at simple conditions, EtONa/EtCOONa produced N-benzyl-2-chloroacetamide 2. Compound 2 was allowed to react with different reagents. These reagents are acetylacetone, ethyl cyanoacetate, ethyl acetoacetate, and diethyl malonate, creating 2-pyridone derivatives with a good yield. The structures of the prepared compounds were elucidated by spectral data (IR, 1HNMR, and 13CNMR). The synthesized compound was tested for its antimicrobial activity against the Gram-positive (Staphylococcus aureus) and the Gram-negative (Escherichia coli) bacteria. In addition, the antifungal activities of the compounds were tested against two fungi (Candida albicans and Aspergillus flavus). Molecular docking studies were applied using the Autodock vina method. Theoretical methods prove all the experimental results by using molecular docking using Autodock vina and by ADEMT studies. The docking results represent that compound 20 had the best docking free energy, and it is the effective compound toward the selected bacterial and fungal proteins. ADME studies showed that the only compound 18 could cross the blood–brain barrier, and compound 15 was predicted to be soluble.

Objectives

Diet is the major modifiable risk factor for the onset of insulin resistance and its progression into diabetes. In the present study the effect of various dietary fats on inflammatory homeostasis and glucose tolerance is investigated in high fat and high fructose fed mice model.

Methods

C57/BL6J mice were divided into four groups and fed a casein-based diet containing high fructose (45%) and high fat (24%) (clarified butter oil [CBO]; safflower oil [SFFO] and lard oil [LO]) for 120 days; oral glucose tolerance (OGTT), plasma lipid profile and plasma & adipose tissue cytokines levels were compared with the control diet (10% groundnut oil and 59.5% starch) fed animals.

Results

The total cholesterol and triglycerides were higher in CBO and LO fed animals with glucose intolerance and increased body weights; liver and white adipose tissue weights were higher in CBO and LO fed animals respectively. CBO feeding increased the plasma (IFN-γ) and adipose tissue cytokines (IFN-γ, IL-10, IL-6 & TNF-α). LO feeding increased plasma IFN-γ, TNF-α and IL-1β and adipose tissue IL-6. SFFO feeding decreased body weight and tissue cytokines and increased plasma IFN-γ levels without causing impairment in the glucose tolerance.

Conclusions

Consumption of a high fructose and high fat diet which mimic the present-day dietary pattern resulted in altered inflammatory homeostasis and impairment in glucose tolerance in 24% CBO and LO fed animals. The deleterious effects of high fructose feeding were reversed in SFFO fed mice possibly due to the presence of oleic and linoleic acids.

Objectives

The cut off values for serum high sensitivity C-reactive protein (hsCRP), ferritin, interleukin 6 (IL-6) and plasma D-dimer could be of profound help in detecting COVID-19 patients at risk of adverse outcomes. Therefore, the aim of the present study is to determine the cut off values of the serum hsCRP, ferritin, IL-6 and plasma D-dimer in predicting mortality in COVID-19 patients.

Methods

Four hundred RT-PCR confirmed cases of COVID-19 were sub divided into two groups based on their outcome during hospitalisation. Group I consisted of survivors and Group II consisted of non-survivors. The survivors were further divided into three sub-groups: mild, moderate and severe based on the severity of infection. The laboratory data of serum hsCRP, ferritin, IL-6 and plasma D-dimer for all these patients was retrieved from the Medical Record Section of the Hospital.

Results

Mean serum hsCRP, ferritin, IL-6 and plasma D-dimer levels were significantly higher in non-survivors as compared to survivors of COVID-19. The levels of these biomarkers correlated with the severity of COVID-19 illness. ROC curve analysis revealed that plasma D-dimer is having a better predictive value as compared to other parameters in predicting mortality in COVID-19.

Conclusions

The serum hsCRP, ferritin, IL-6 and plasma D-dimer levels could be used in risk stratification of COVID-19 patients. The optimum cut off given by the current study could be considered in predicting adverse outcome in these patients. Amongst the many studied biomarkers, plasma D-dimer might be the best early biomarker to predict mortality in COVID-19 patients.

Frequent repetition of vocabulary is essential for effective language learning. To increase exposure to learning content, this work explores the integration of vocabulary tasks into the smartphone authentication process. We present the design and initial user experience evaluation of twelve prototypes, which explored three learning tasks and four common authentication types. In a three-week within-subject field study, we compared the most promising concept as mobile language learning (MLL) applications to two baselines: We designed a novel (1)UnlockAppthat presents a vocabulary task with each authentication event, nudging users towards short frequent learning session. We compare it with a (2)NotificationAppthat displays vocabulary tasks in a push notification in the status bar, which is always visible but learning needs to be user-initiated, and a (3)StandardAppthat requires users to start in-app learning actively. Our study is the first to directly compare these embedding concepts for MLL, showing that integrating vocabulary learning into everyday smartphone interactions viaUnlockAppandNotificationAppincreases the number of answers. However, users show individual subjective preferences. Based on our results, we discuss the trade-off between higher content exposure and disturbance, and the related challenges and opportunities of embedding learning seamlessly into everyday mobile interactions.

Hololingo! is a social virtual reality app for real-time immersive distance learning of German as a Foreign Language (GFL). The acquisition of discoursive oral language skills for applied authentic contexts is challenging for group-based classroom settings and is often outsourced to autonomous analogue tandem learning. We operationalise a Digital Game-Based Language Learning (DGBLL) approach for distance learning, which relieves tandems from overstraining autonomy and self-guidance. Hololingo! supports tandems in their learning activities by providing entertaining communicative, collaborative, and didactically designed team tasks. These are embedded in a narrative adventure, target linguistic phenomena, and support the holistic acquisition of oral discourse competencies and fluency. The combination of the tandem principle, immersive Social VR gamification, barrier-free access to a global pool of expert/native speakers, and a curricular connection through task selection facilitates language learning and provides transcultural contacts. App development follows a Design-Based-Research cycle of conception, implementation, and evaluation. The results of a qualitative discourse analysis of the learning interaction are discussed with regard to tandem role behaviour, the relation between task design and communication as well as affective and creative behaviour.

Writing is an essential cultural technique, and the resulting artefacts are an important part of cultural heritage. The Cluster of Excellence ‘Understanding Written Artefacts’ is an interdisciplinary and cross-cultural long-term project dedicated to studying so-called ‘written artefacts (WA)’. Our work introduces immersive technologies such as virtual, augmented, and mixed reality to the research cluster for the first time.

In this paper, we outline the scope of our research project and present our current implementations of immersive applications based on two scenarios involving inscribed spaces. So far, immersive technologies have not been used in academia to create research focused applications for exploring, analysing, and understanding WA within their inscribed space, including providing access to appropriate spatial and temporal contexts. Thus, we collaborate closely with researchers from the humanities to create interactive and immersive applications for the novel field of WA research.

The results of our preliminary user study show high ratings in the sense of presence in the virtual environments and indicate that immersive spatial context could add new perspectives for understanding WA. We hope to provide valuable insights on the design of immersive applications to support future research in novel fields.
Wandel durch Austausch – Gespräch mit Bettina Wilhelm über den Sinologen Richard Wilhelm und das I Ging
Authors: Qi Jiafu , Wilhelm Bettina , Sun Lixin , Huang Yirong
Published: March 2022

Der Sinologe und Theologe Richard Wilhelm leistete durch seine Übersetzungen klassischer chinesischer philosophischer Werke und durch seine bahnbrechende Erforschung der chinesischen Kultur einen großen Beitrag zur Überlieferung der klassischen chinesischen Philosophie im Westen ebenso wie zum Kulturaustausch zwischen China und Deutschland. In einem Dokumentarfilm unter der Regie seiner Enkelin Bettina Wilhelm führt sie einen Dialog mit ihrem Großvater, indem sie seine Spuren in China und Deutschland nachzeichnet. Ein Gespräch zwischen Bettina Wilhelm und Forschern, Lehrern und Schülern über diesen Film offenbart die tief reichende Bedeutung des Buches I Ging, nämlich „Wandlungen“, dessen Philosophie Richard Wilhelm in den Bann zog. Aufgeschlossenheit gegenüber Wandel (die Begegnung mit einer anderen Kultur bedeutet ebenfalls Wandel) wird als ein geeigneter Weg angesehen, um mit Veränderungen umzugehen und im Strom des Lebens mit zu schwimmen.
Improvement and metallurgy of current-related heating problem of circuit breakers made of AgSnO2 and AgCdO
Authors: Kalkanli Ahmet , Güven Şengül
Published: March 2022

Recent developments in technology increase the application area of electronic systems used in cars and commercial vehicles day by day. Along with the increase in the features expected from the vehicles, the battery capacities required to meet the desired features also increase. Especially in commercial vehicles, high-capacity battery systems are used depending on the function of the vehicle. Circuit breaker systems providing high voltage and current are used to intervene in the event of a possible problem from the batteries. During the operation of the vehicle, heat is generated due to the high current passing through the circuit breakers. In this study, different materials and surface contact forms were examined to solve the heating problem of circuit breakers operating at high voltage and current values. AgSnO2 and AgCdO coating materials were used for surface coatings of rivets used in circuit breakers. Moreover, rivet groups with various surface contact geometries such as flat–flat and curved–flat were used for each material. After applying 24 V–250 A values to the different materials and rivets of different surface shape geometries, thermal and metallographic analyses were performed. The experimental study showed that the best thermal results under resistive load are formed by the curved–flat contact geometry of the AgSnO2 coating material.

The Iraqi GNSS network was installed in 2005 with help from the USA and UK. The network consists of seven GNSS stations distributed across Iraq. The network GNSS data have been comprehensively analyzed in this study; this, in turn, allowed us to assess the impact of various geophysical phenomena (e. g., tectonic plate motion and Earthquakes) on its positional accuracy, stability, and validity over time. We processed daily GPS data, spanning over more than five years. The Earth Parameter and Orbit System software (EPOS.P8), developed by the German Geoscience Research Center (GFZ), was used for data processing by adopting the Precise Point Positioning (PPP) strategy. The stacked time series of stations coordinates was analyzed after estimating all modeled parameters of deterministic and stochastic parts using the least-squares technique. The study confirmed a slight impact of the recent M 7.3 Earthquake on the Iraqi GNSS stations and concluded that the stations are stable over the study period (2013 up to 2018) and that the GNSS stations represent the movement of the Arabian plate.
