Authors: Fontana Marco , Bejtka Katarzyna , Gho Cecilia , Merkens Stefan , Chuvilin Andrey , Pirri Candido Fabrizio , Chiodoni Angelica
Published: December 2023

Electrochemical Liquid Phase Transmission Electron Microscopy (EC-LPTEM) is envisioned as an invaluable tool for the investigation of structural and morphological properties of functional materials in electrochemical systems for energy transition applications, especially in aqueous-based electrolytes. However, one major issue in accessing electrochemical conditions (e.g. overpotential, current density) relevant for energy applications (e.g. heterogeneous catalysis, batteries) is the saturation of the liquid cell by gaseous products resulting both from the reaction of interest and from water decomposition at the Working electrode (WE) and Counter electrode (CE). In this work, the performance of an optimized liquid cell geometry is investigated, with the aim of fine tuning the experimental set-up and optimizing the functional activity of the active materials under investigation. Ex situ and in situ comparative flow experiments are carried out in order to understand the role of the optimized liquid flow configuration for electrochemical experiments in aqueous electrolytes. The key role of the optimized flow geometry in reducing the formation of gas bubbles at both the WE and CE is highlighted, coupled with an improvement in the removal of gaseous products at the WE/CE. Finally, the validation of the optimized microfluidic set-up, through the electrodeposition of Zn nanostructures in aqueous electrolyte, is presented as a proof-of-concept experiment showing that the optimized geometry provides access to experimental conditions which have not been available with the standard liquid cell configuration.

Authors: Beaven Anna , Marshman Zoe
Published: December 2023

Introduction
Access to dental services is a growing problem for older people in the UK. The aim of this scoping review is to identify the barriers and facilitators influencing older people’s ability to accessing oral healthcare in the UK based on the existing literature.
Methods
The scoping review followed the framework proposed by Levac and colleagues (2010). Peer-reviewed literature was retrieved in April 2023 from Web of Science, MEDLINE, PsychINFO and CINAHL for the period 1973–2023. After screening, data was extracted to identify barriers and facilitators mapped to individual, organisational and policy level factors. The themes generated were used to identify gaps in the literature and policy recommendations.
Results
Overall, 27 studies fulfilled the inclusion criteria. Most studies published were from England; there was a large representation of opinion pieces. The main barriers and facilitators related to cost of services, perceptions of dentistry, availability of services, and both the dental and social care workforce.
Conclusion
Multiple barriers exist surrounding access to dental care for older people. Various facilitators exist but not all are successful. More research needs to be carried out on older people’s access to dental services in the community, particularly for the oldest old and minority groups.

Published: December 2023

Background: Glaucoma causes persistent and increasing deterioration of visual function since it is an untreatable, irreversible condition that causes vision loss. Optic nerve protection is an important treatment for glaucoma with controlled intraocular pressure (GPCI), but to date, there is no universally accepted effective optic nerve protection agent. Acupuncture can protect the optic nerve by increasing blood flow to the eye. However, fear of pain or the limitations of treatment place and time lead to poor patient compliance. Press-needle therapy is a characteristic of traditional Chinese medicine (TCM) external treatment methods; its safety is high, the effect is fast and lasting, it is easy to operate, and it has high patient compliance. Therefore, the aim of this study protocol is to evaluate the safety and effect of press-needle therapy in patients with GPCI.
Methods: One hundred and ninety-two participants aged 18 to 75 years with GPCI will be recruited from the Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, MianYang Hospital of TCM and Mianyang Wanjiang Eye Hospital. All participants will be allocated to two treatment groups, including the experimental group or sham press-needle group, at a ratio of 1:1 and will receive press-needle and comfort needle, respectively, for the same 4-week period. The primary outcomes will include best-corrected visual acuity (BCVA), optical coherence tomography angiography (OCTA), colour Doppler flow imaging (CDFI), and visual field assessment; the secondary outcomes will include intraocular pressure (IOP) and traditional Chinese medicine (TCM) clinical symptom scales. The primary outcomes and safety assessments will be measured at baseline and 4 weeks thereafter, and the secondary outcomes will be measured at baseline and 1, 2, 3, and 4 weeks thereafter.
Discussion: The results of this research will provide substantial evidence regarding the efficacy of press-needle therapy in improving visual function and eye blood circulation in GPCI patients.

Effects of intimate partner violence and homophobic bullying on ART adherence among young Thai men who have sex with men: a causal mediation analysis
Authors: Cheung Doug H. , Reeves Alexis N. , Waratworawan Worawalan , Kongjareon Yamol , Guadamuz Thomas E.
Published: December 2023

Background: Adherence to antiretroviral therapy is crucial in determining health outcomes and secondary HIV transmission for people living with HIV/AIDS. Young men who have sex with men (YMSM) living with HIV are often challenged by the prevailing experiences of psychosocial stressors, such as intimate partner violence and homophobic bullying, which may negatively affect their HIV care engagement.
Methods: This study is the first to utilize a prospective cohort design (N= 185) involving YMSM living with HIV in Thailand. We examined the effects of intimate partner violence and homophobic bullying on ART adherence. We also tested the mediating effect of depression on the relationship between intimate partner violence and homophobic bullying on ART adherence.
Results: We found that intimate partner violence (AOR: 2.58, 95% CI: 1.13, 5.42) and homophobic bullying (AOR: 2.40, 95% CI: 1.26, 4.48) were associated with subsequent ART nonadherence. Moreover, depression partially mediated 17.4% (95% CI: 0.75%, 56%) of the effect of homophobic bullying on ART nonadherence.
Conclusions: The results suggest that tailored interventions to optimize ART adherence should address the impacts of intimate partner violence and homophobic bullying for HIV+ YMSM. The screening and subsequent treatment of depression alone may not be sufficient to address the effects of intimate partner violence, homophobic bullying, and possibly other MSM-specific psychosocial stressors on ART adherence.

Published: December 2023

Introduction The relationship between posture and temporomandibular disease (TMD) is unclear. The aim of our study was to determine the influence of manual therapy (MT) on posture in TMD patients compared with healthy subjects.
Material/Method After consideration of inclusion and exclusion criteria, 30 subjects were included. These were divided into two groups: group A comprised 15 healthy subjects and group B 15 patients with present proven TMD disease. Rasterstereographic images were taken at different times. Group A subjects were scanned twice within half a year and group B before initiation as well as after the first MT and after completion of the prescribed MT. The different posture variables were calculated using DIERS Formetric software.
Results To illustrate the differences between the two groups, 10 different postural variables were examined. Significant differences between the two groups were observed in pelvic tilt, surface rotation, and kyphotic apex. Pelvic tilt: mean = 7.581, p-value = 0.029; surface rotation: mean = 3.098, p = 0.049; and mean kyphotic apex = 11.538 and 11.946, respectively, with p-values of 0.037 and 0.029, respectively.
Conclusion MT leads to a change in posture in TMD patients. This could influence the course of TMD treatment.

Authors: Kent Monique Potvin , Bagnato Mariangela , Remedios Lauren , Guimarães Julia Soares , Gillis Grace , Soto Carolina , Hatoum Farah , Pritchard Meghan
Published: December 2023

Background
Children and adolescents are exposed to a high volume of unhealthy food marketing across digital media. No previous Canadian data has estimated child exposure to food marketing across digital media platforms. This study aimed to compare the frequency, healthfulness and power of food marketing viewed by children and adolescents across all digital platforms in Canada.
Methods
For this cross-sectional study, a quota sample of 100 youth aged 6–17 years old (50 children, 50 adolescents distributed equally by sex) were recruited online and in-person in Canada in 2022. Each participant completed the WHO screen capture protocol where they were recorded using their smartphone or tablet for 30-minutes in an online Zoom session. Research assistants identified all instances of food marketing in the captured video footage. A content analysis of each marketing instance was then completed to examine the use of marketing techniques. Nutritional data were collected on each product viewed and healthfulness was determined using Health Canada’s 2018 Nutrient Profile Model. Estimated daily and yearly exposure to food marketing was calculated using self-reported device usage data.
Results
On average, children viewed approximately 1.96 instances of food marketing in 30 minutes, while adolescents viewed an estimated 2.56 ads in the same timeframe. Both children and adolescents were most exposed on social media platforms (83%), followed by mobile games (13%). We estimated that children are exposed to 1.96 ads/child/30-minutes (4067 ads/child/year) and adolescents are exposed to 2.56 ads/adolescent/30-minutes (8301 ads/adolescent/year), on average. Both children and adolescents were most exposed to fast food promotions (22% of advertisements) compared to other food categories. Nearly 90% of all marketing instances were considered less healthy according to Health Canada’s proposed 2018 Nutrient Profile Model, and youth-appealing marketing techniques such as graphic effects and music were used frequently.
Conclusions
Using the WHO screen capture protocol, we were able to determine that child and adolescent exposure to the marketing of unhealthy foods across digital media platforms is high. Government regulation to protect these vulnerable populations from the negative effects of this marketing is warranted.
Impact of E-learning for teaching electrocardiography. A comparative study of asynchronous and synchronous groups
Authors: Mendez Juan , Gallo Sofia , Jaramillo Carlos , Ramirez Alejandra
Published: December 2023

Background
This study proposes a methodology for e-electronic teaching of electrocardiography for undergraduate medical students. A progressive sequence, assessments, and several didactic strategies were applied for both groups. This study aimed to determine the impact of synchronous and asynchronous virtual teaching of electrocardiography on two groups of final-year medical students.
Methodology
A mixed method study was conducted. The impact of teaching was quantified by comparing the results of pretests at the beginning of the course, posttest 1 at the end of the course, and posttest 2 four months later. The assessments were based on electrocardiograms of real patients. For the qualitative analysis, in-depth semistructured interviews were conducted to provide other insights into the development of competencies and significant learning during and after the course. The courses were designed based on cognitive load theory for multimedia learning and didactic transposition as the basis for implementing didactic strategies.
Results
The results indicate a positive impact on the teaching of electrocardiography, with students developing competencies for reading and interpreting electrocardiograms and significant learning. There were statistically significant differences (Student's t test; p≤0.0001) between the pre- and posttest exams for both modalities, but no differences between synchronous and asynchronous learning (p≥0.579).
Conclusion
This result suggests that both modalities positively impact the teaching of electrocardiography. Similarly, the qualitative analyses show that participants report the development of assurance and confidence, as well as the consolidation of knowledge and greater responsibility when handling the electrocardiograms of real patients. These results agree with the quantitative analyses.
Damage-caused residual curvatures in symmetric laminates
Authors: Pupurs Andrejs , Varna Janis
Published: December 2023

Thermo-mechanical response of [90n/0m]s carbon/epoxy and glass/epoxy cross-ply laminates in 4-point bending is analyzed experimentally and analytically. Intralaminar cracks in surface 90°-plies and local delaminations introduced in one of the 90°-plies at large deflections reduce the laminate bending stiffness and make the laminate asymmetric due to differences in the damage state in the layers. The latter leads to residual thermal curvature that increases with intralaminar crack density and with growing local delaminations. In the present study optical microscopy was used for crack density quantification. It was also found experimentally that small local delaminations develop in the initial stage of damage evolution and under increasing load they grow rapidly from the existing and newly created crack tips. The effect of damage on residual curvature and the bending stiffness was analyzed using an analytical method, where the concept of the effective stiffness of damaged ply is used in the classical laminate theory. Analytical results were validated with a 3-D FEM simulation of the damaged laminate in a 4-point bending test. It is shown that the analytical approach gives an accurate description of experimental results regarding two independent sets of data: the residual curvature; and the laminate bending stiffness with evolving micro-damage. It also renders a better insight in the mechanics of the phenomena and allows estimation of the extent of local delaminations that is difficult to measure in tests.

Published: December 2023

Chronic endometritis (CE) is recognized as an infectious and inflammatory disorder of the endometrium. Despite previous studies emphasizing the strong association between CE and recurrent pregnancy loss (RPL), their interaction and molecular mechanisms remain elusive. In our study, we aimed to explore the common gene signatures and potential molecular mechanism shared by CE and RPL. Utilizing GEO datasets, we identified two modules significantly correlated with CE and one module associated with RPL through weighted gene co-expression network analysis (WGCNA). The ClueGO enrichment analysis results of shared genes showed that high IFN response was a shared feature in CE and RPL, which was confirmed by the results of differential expression analysis in two datasets. The unique gene signatures were also explored for the potential molecular mechanism in CE and RPL. Moreover, the constructed miRNA-target network indicated a potential regulatory role of hsa-miR-27a on the shared IFN-induced genes. Our study firstly provides the insights into the shared gene signatures and potential molecular mechanism of CE and RPL. Furthermore, the IFN-induced genes might be related to the inflammation of endometrium and the occurrence of CE, which contributed to the identification of effective biomarkers or potential therapeutic targets for RPL patients.
Enhancing Data Security in Smart Cities with a Smart Contract-based Architecture and Hyperledger Fabric
Authors: Samanta Saikat
Published: December 2023

A smart city provides innovative services to citizens to improve their quality of life. A smart city generates vast amounts of data as Internet of Things (IoT) integration increases. However, gathering, storing, processing, and analyzing this data can pose significant challenges, particularly given its heterogeneous nature and the fact that citizens often contribute to it. A Linux Foundation project called Hyperledger includes the Hyperledger Fabric (HF), developed by IBM and contributing to Hyperledger's development. This paper suggests a smart contract-based data security network for smart cities that uses HF. Data access rules and data-sharing policies can be enforced using smart contracts. A framework is proposed for integrating multiple smart city applications and services while ensuring data privacy and security. A significant contribution to the existing literature is made by this study, which examines the usefulness of blockchain technology and smart contracts in smart cities for data security.
CT-based radiomics predicts CD38 expression: indirectly reflects clinical prognosis in epithelial ovarian cancer
Authors: Yao Yuan , Zhang Haijin , Liu Hui , Teng Chendi , Che Xuan , Bian Wei , Zhang Wenting , Wang Zhifeng
Published: December 2023

Background
Cluster of differentiation 38 (CD38) has been found to be highly expressed in various solid tumors, and its expression level may be associated with patient prognosis and survival. The study aimed to explore the prognostic value of CD38 expression for patients with epithelial ovarian cancer (EOC) and to construct two computed tomography (CT)-based radiomics models for CD38 expression prediction.
Methods
A total of 333 cases of EOC were enrolled from The Cancer Genome Atlas (TCGA) database for CD38 related bioinformatics and survival analysis. 56 intersection cases from TCGA and The Cancer Imaging Archive (TCIA) databases were selected for radiomics feature extraction and model construction. Logistic regression (LR) and support vector machine (SVM) models were constructed and internally validated using 5-fold cross-validation to assess the performance of the models for CD38 expression levels.
Results
High expression of CD38 was an independent protective factor (HR = 0.540) for overall survival (OS) in EOC patients. 5 radiomics features based on CT images were selected to build models for CD38 expression prediction. In the training set and internal validation set, for the receiver operating characteristic (ROC) Curve, the LR model reached area under the curve (AUC) of 0.739 and 0.732, while the SVM model achieved AUC values of 0.741 and 0.700, respectively. For the precision-recall (PR) Curve, the LR model and SVM model demonstrated AUC of 0.760 and 0.721. The calibration curves and decision curve analysis (DCA) provided evidence supporting the fitness and net benefit of the models.
Conclusions
High expression of CD38 can improve OS in EOC patients. CT-based radiomics models can be a new predictive tool for CD38 expression, offering possibilities for individualized survival assessment for patients with EOC.

Published: December 2023

Cutting edge chipping is a randomly-happened but critical tool failure, which could seriously affect machining quality without effectively and timely treatment especially in the automated machining process. Accurately and timely monitoring chipping is the first key step for properly handling edge chipping issues, while there are still gaps between academic research and industrial application as chipping initiation and propagation are always stochastic especially for milling complex structural parts with mass of ever-changing cutting conditions. This paper proposes a chipping monitoring method for automated milling process based on cutting vibration polar coordinate image features and residual neural network (ResNet) model, which lies on the change of cutting vibration signals that reveal just after an event of edge chipping has occurred. With the creatively proposed polar coordinate transform method, cutting vibration signals are first preprocessed for real-time chipping detection. The preprocessed signals with easily distinguished shape features of polar coordinate images, are then employed for developing a ResNet50 based classification model. And consequently, the cutting edge chipping could be monitored in almost real time. Experimental validation for real-time chipping detection has been conducted with the proposed method. The accuracy of No. 5 ~ 8 experiments are 92%, 88%, 83% and 84%, respectively. More importantly, the method is suited for edge chipping monitoring for milling complex structural parts, where effects of constantly changing cutting conditions have been eliminated.

Authors: Wang Tingrui , Wang Xingxu , Lin Zijing , Han Shanshan , Xiao Zhesi , Ming Jia
Published: December 2023

Purpose: Estrogen and Progesterone receptors(ER, PR) are essential indicators for Breast cancer(BC) therapy, but the unbalanced expression effect remains unclear. This study aimed to explore the features of HER2-negative BC with different expressions of ER and PR.
Methods: 106,742 women patients with BC in SEER from 2010 to 2015 were divided into four groups: ER-negativePR-negative (NN), ER-negativePR-positive (NP), ER-positvePR-negative (PN), ER-positivePR-positive (PP). The significant results of Cox Hazard regression were used to build the nomograms of NP and PN.
Results: Groups of ER-negative (median age<60) were younger than ER-positive. Proportions about Grade III-IV of NP and NN were significantly higher than PN and PP (III: 81.41%, 81.71%, 44.26%, 18.63%; IV: 0.73%, 0.61%, 0.29%, 0.10%). Metastasis rates in NN, NP, and PN were higher than in PP (3.45%,3.02%,3.26%, 2.07%). The survival line of NP was equal to NN (P=0.65) but lower than PP (P=0.00011); PN was lower than PP but significantly higher than NN(P<0.0001). C-index of NP and PN prediction models was 0.721 (95%CI: 0.679-0.761) and 0.750 (95%CI: 0.736-0.763).
Conclusion: HER2-negative BC with uneven expressions of ER and PR differs from those with consistent presentations. NP and NN have similar clinical features: worse grading, larger tumor diameter, and higher incidence of peripheral invasion and metastasis rates. The survival of NP and PN was worse than PP; NN was consistent with NP but lower than PN from the curve. The two nomograms were validated effectively and had a moderate ability.

Published: December 2023

Satellite technology has emerged as a key tool for effective management and assessment of natural disasters. However, the challenge of accurately estimating impacted populations and assessing building damage, often obscured from aerial views, persists. To address this, the integration of imagery and textual data from social networks offers a promising solution. This study employs Twitter and Flickr datasets, using SVM, CNN, XGBoost, Logistic Regression, and Gradient Boost to extract insights. The sentiment analysis component categorizes disaster-affected individuals' emotions as panic, neutral, or non-panic. The Logistic Regression model excels in text classification, boasting an impressive 88.99% accuracy on the test dataset and 83.45% on training. The framework introduces an Aid analysis model, which gives us an impressive accuracy of 83.16% for the classification of tweets based on the aid sought by people through tweets. Image classification employs CNN, achieving 83.29% accuracy to comprehend disaster impact visually. Given real-time social media responses, the system assists government and organisations promptly, prioritising assistance. It serves as a dependable aid resource, enabling efficient responses tailored to affected communities. Thus, this approach holds potential to significantly enhance disaster relief efficacy.
A multiobjective metaheuristic-based container consolidation model for cloud application performance improvement
Authors: Bracke Vincent , Santos José , Wauters Tim , De Turck Filip , Volckaert Bruno
Published: December 2023

This work describes an approach to enhance container orchestration platforms with an autonomous and dynamic rescheduling system that aims at improving application service time by co-locating highly interdependent containers for network delay reduction. Unreasonable container consolidation may however lead to host CPU saturation, in turn impairing the service time. The multiobjective approach proposed in this work aims to improve application service time by minimizing both inter-server network traffic and CPU throttling on overloaded servers. To this extent, the Simulated Annealing combinatorial optimization heuristic is used and compared on its relative performance towards the optimal solution obtained by Mathematical Programming. Additionally, the impact of the proposed system is validated on a Kubernetes cluster hosting three concurrent applications, and this under varying load scenarios. The proposed rescheduling system systematically i) improves the application service time (up to 27.2% from our experiments) and ii) surpasses the improvement reached by the Kubernetes descheduler.

Published: December 2023

Among adolescents and young adults, self-reported baseline psychological distress was quite high during the COVID-19 pandemic. As a vulnerable group, college students suffer from serious psychological problems such as anxiety and depression during the COVID-19 pandemic. Despite the fact that COVID-19 no longer constitutes a public health emergency of international concern and the reduction of COVID-19 pandemic restrictions in March 2023, the change of college students' mental health remains unclear. In March and June 2023, college students in Kunming, China, were investigated by the Self-Rating Anxiety Scale, Self-Rating Depression Scale, and Pittsburgh Sleep Quality Index. After the COVID-19 pandemic restrictions were reduced, the results of the scale indicated anxiety (-0.6%, 21.6%-21%), mild anxiety (+ 0.5%, 16.50%-17.0%), moderate anxiety (-0.7%, 3.94%-3.2%), and severe anxiety (-0.4%, 1.2%-0.8%). Depression (-8.1%, 37.2%-29.1%), mild depression (-5.2%, 19.4%-14.2%), moderate depression (-2.2%, 16.7%-14.5%), or severe depression (-0.7%, 1.1%-0.3%) among college students. Good sleep quality (0%, 72.3%-72.3%) and poor sleep quality (0%, 27.7%-27.7%); anxiety or depression (-6.5%, 39.7%-33.2%) among college students. The incidence of anxiety and depression in college students was reduced, after the reduction of COVID-19 pandemic restrictions.

The brightness of an emitter is ultimately described by Fermi’s golden rule, with a radiative rate proportional to its oscillator strength times the local density of photonic states (LDOS). Since the oscillator strength is an intrinsic material property, the quest for ever brighter emission has relied on LDOS engineering, via dielectric or plasmonic resonators1,2. In contrast, a much less explored avenue is to boost the oscillator strength, and hence the emission rate, via a collective behavior termed superradiance. Recently, it had been proposed3 that the latter can be realized via the giant oscillator-strength transitions of a weakly confined exciton in a quantum well when its coherent motion extends over many unit cells. Here, we demonstrate single-photon superradiance in perovskite quantum dots (QDs) with a sub-100 ps radiative decay time, almost as short as the reported exciton coherence time4. The characteristic dependence of radiative rates on QD size, composition, and temperature suggests the formation of giant transition dipoles, as confirmed by effective-mass calculations. The results aid the development of ultrabright, coherent quantum-light sources and attest that quantum effects, e.g., single-photon emission, persist in nanoparticles ten times larger than the exciton Bohr radius.

Published: December 2023

The purpose of this study is to generate non-verbal items for a visual reasoning test using templated-based automatic item generation (AIG). The fundamental research method involved following the three stages of template-based AIG. An item from the 2016 4th-grade entrance exam of the Science and Art Center (known as BİLSEM) was chosen as the parent item. A cognitive model and an item model were developed for non-verbal reasoning. Then, the items were generated using computer algorithms. For the first item model, 112 items were generated, and for the second item model, 1728 items were produced. The items were evaluated based on subject matter experts (SMEs). The SMEs indicated that the items met the criteria of one right answer, single content and behavior, not trivial content, and homogeneous choices. Additionally, SMEs' opinions determined that the items have varying item difficulty. The results obtained demonstrate the feasibility of AIG for creating an extensive item repository consisting of non-verbal visual reasoning items.

The vulnerability of People in general and farmers in particular in the flood affected state of Bihar need to be mitigated for creating resilience and sustainability of farming. This study is the estimation on the social vulnerability as perceived of area adversely affected by the flash flood of the state Bihar in the year of 2021. The interview was conducted personally with 40 people engaged in farming occupation using of pre- structured interview schedule in the flood prone area of the state Bihar. The data were analysed statistically applying tools viz descriptive statistics, correlation, regression using statistical software SPSS-23. It was found that family size (x6), vulnerable members (x9), age (x1) and perception on occupation (x4) of the flood affected farmers were negatively and significantly correlated with perception on social vulnerability of the farmers. It was also found that credit load (x16), education (x2) and social participation (x11) were positively and significantly correlated with the perception on social vulnerability of the flood affected farmers in the increasing strength of association. The independent variables such as. age (x1), education (x2), perception on occupation (x4), family size (x6), vulnerable members (x9), social participation (x11) and credit load (x16) have all together explained 82.4 per cent of the variance embedded in the social vulnerability as perceived by flood affected farmers.The study concluded that all the estimated significant socio-economic agro-economic and socio-psychological characteristics of flood affected farmers determines the perception on social vulnerability of farmers which in turn will help policy makers to undertake suitable remedial measures to improve the precarious situation in a better way not only by developing infrastructures but also with appropriate improved agricultural technologies in the form of flood tolerant varieties, crop protection measures and farm mechanization so that the farming occupation can become resilient and sustainable.

TEACHERS PER(FORMING) GENDER: CORPOREITIES, HORMONES AND THE SCIENCE/CHEMISTRY EDUCATION. The discussions on human rights, gender and race are global and urgent. Using elements of participatory research, this study aimed to analyze, understand and characterize the formative process of postgraduate student’s knowledge and reflections mobilized on the gender and sexuality in the teaching of Science/Chemistry. The results show that the students started from a counterhegemonic intentionality regarding the way in which the issue of hormones is traditionally treated in Science/Chemistry teaching. Furthermore, they recognized scientific knowledge as active in the production and reproduction of systems of oppression teacher on diversity education transgressive way of teaching the subject, beyond the binary conception of gender. The results revealed the possibility of rationalizing sexual and gender dissidences as a form of innovation, as well as the importance of formative processes to rethink dominant epistemologies for the advancement of educational and practices in and for education, to break with the cisheteromonormative perspective that erases the production and existence of people who flee from this logic in Science/Chemistry.

The recent SARS-COV-2 pandemic has sparked the adoption of wastewater-based epidemiology (WBE) as a low-cost way to monitor the health of populations. In parallel, the pandemic has encouraged researchers to openly share their data to serve the public better and accelerate science. However, environmental surveillance data are highly dependent on context and are difficult to interpret meaningfully across sites. This paper presents the second iteration of the Public Health Environmental Surveillance Open Data Model (PHES-ODM), an open-source dictionary and set of data tools to enhance the interoperability of environmental surveillance data and enable the storage of contextual (meta)data. The data model describes how to store environmental surveillance program data, metadata about measurements taken on various specimens (water, air, surfaces, sites, populations) and data about measurement protocols. The model provides software tools that support the collection and use of PHES-ODM formatted data, including performing PCR calculations and data validation, recording data into input templates, generating wide tables for analysis, and producing SQL database definitions. Fully open-source and already adopted by institutions in Canada, the European Union, and other countries, the PHES-ODM provides a path forward for creating robust, interoperable, open datasets for environmental public health surveillance for SARS-CoV-2 and beyond.

O objetivo deste artigo é realizar uma revisão de literatura sobre o processamento digital de imagens e sua aplicação no mapeamento de uso e cobertura da terra. A revisão de literatura utilizou a abordagem híbrida, bibliométrica e sistemática. Sob a perspectiva bibliométrica foi valorizada a abordagem quantitativa, por meio de métricas do Bibliometrix, através do software R. Para esta pesquisa, foi utilizada a frase Digital image processing for land use and land cover mapping. A abordagem sistemática foi realizada através de análise quali-quantitativa das variáveis tipo de sensor, se estudos realizados em área rural e urbano, o tipo de abordagem e a escala de análise. Os resultados revelaram o mapeamento de 713 publicações, dentre as quais 324 e 389 das bases Scopus e Web of Science, respectivamente, publicados de 1973 a 2022, período total cobriu 49 anos, excluídos as repetições de 88 publicações, o que resultou em 625 publicações. Todos os 625 artigos foram analisados, destaca-se pesquisas em zona rural, uso de imagens LANDSAT e classificação por meio de métodos clássicos.
Jedyność Boga jako źródło jedności Chrześcijan „W Chrystusie” (Ga3,20. 28). Przesłanki egzegetyczno-retoryczne
Authors: Sztuk Dariusz
Published: December 2023

Aby być dziedzicami obietnic złożonych przez Boga Abrahamowi, Galaci zabiegali o zapewnienie sobie jedności z Abrahamem. Upatrujący to bardziej w zewnętrznym zachowaniu Prawa Iudaizzantes twierdzili, że konieczne jest przyjęcie obrzezania. W analizowanym fragmencie widzimy, że Apostoł Paweł wykazuje, iż wiara w Chrystusa i chrzest ustanawiają tak bliskie więzi międzywierzącymi i Abrahamem, że są one silniejsze niż te wynikające z obrzezania. Już przez wiarę i chrzest chrześcijanie należą do Chrystusa. A to On właśnie jest jedynym potomkiem, którego dotyczy obietnica. Wynika więc z tego jasno, żewierzący w Chrystusa są „potomkami Abrahama i zgodnie z obietnicą – dziedzicami”. Wartością więc, w liście wyrażoną przez proste formy liczebnika unum, jest włączenie adresatów i wszystkich chrześcijan w krwiobieg Bożych planów. Znajdują one swój wyraz w wyznawaniu wiary w jedynego Boga, który nie tylko wychowuje i zbawia swój lud, ale również prowadzi do komunii życia z Jezusem Chrystusem wszystkich tych, którzy „pochodzą z wiary” (Ga 3,7). W tej perspektywie sąw szerokim znaczeniu jedynymi potomkami, którym Bóg złożył swoją obietnicę.
Relational Aspect Of Humanity In The Light Of (Selected) Athropological Asumptions Of The Theology Of The Body By John Paul II
Authors: Młynarski Stanisław
Published: December 2023

The aim of the article is to present (selected) assumptions of anthropology that underlies the theology of the body of John Paul II. The author analyzes its main assumptions and confronts them with inadequate anthropology, which underlies the sexual revolution that is considered as distorting the sense of the human body in the light of Revelation. This study focuses on the analysis of the contents of the catechisms of John Paul II referring to texts about human relativity andthe role that the body plays in this context. The analysis does not include those texts that refer to the reality of the sin of the first people. The text also aims at emphasizing the importance of the theology of the body for modern man and his spiritual development.

Interactions of Polyphenolic Gallotannins with Amyloidogenic
Polypeptides Associated with Alzheimer’s Disease: From Molecular
Insights to Physiological Significance
Authors: Khalifa Jihane , Bourgault Steve , Gaudreault Roger
Published: December 2023

Polyphenols are natural compounds abundantly found in plants. They are known for
their numerous benefits to human health, including antioxidant properties and anti-inflammatory
activities. Interestingly, many studies have revealed that polyphenols can also modulate the formation
of amyloid fibrils associated with disease states and can prevent the formation of cytotoxic oligomer
species. In this review, we underline the numerous effects of four hydrolysable gallotannins
(HGTs) with high conformational flexibility, low toxicity, and multi-targeticity, e.g., tannic
acid, pentagalloyl glucose, corilagin, and 1,3,6-tri-O-galloyl-β-D-glucose, on the aggregation of
amyloidogenic proteins associated with the Alzheimer’s Disease (AD). These HGTs have demonstrated
interesting abilities to reduce, at different levels, the formation of amyloid fibrils involved
in AD, including those assembled from the amyloid β-peptide, the tubulin-associated unit, and the
islet amyloid polypeptide. HGTs were also shown to disassemble pre-formed fibrils and to diminish
cognitive decline in mice. Finally, this manuscript highlights the importance of further investigating
these naturally occurring HGTs as promising scaffolds to design molecules that can interfere
with the formation of proteotoxic oligomers and aggregates associated with AD pathogenesis.
