On the benefits of structured composite electrodes in solid oxide cells
Authors: Budáč Daniel , Carda Michal , Adamová Nela , Sádecká Monika , Paidar Martin , Híveš Ján 
Published: November 2023

AbstractFunctional composites of electronic and ionic conductors are the backbone of oxygen and fuel electrodes in solid oxide cells. A typical oxygen electrode is fabricated from a lanthanum strontium manganite and yttria-stabilized zirconia (LSM-YSZ) composite, while the fuel electrode is based on a Ni-YSZ cermet. While the composite materials exhibit enhanced kinetic capabilities, the electron-conductive phases, i.e., LSM and Ni, exhibit high electrical conductivity. The goal of this study was to develop an electrode layout with enhanced performance by tailoring the benefits of both, the composites and the single-phase electron conductors, within individual electrodes. The electrodes were fabricated in a two-layer layout with different thicknesses by screen-printing: composite material layer, electron-conductive material. The results suggested that the presence of YSZ is essential in the entire electrode body of a fuel electrode for enhanced performance as it increases the triple phase boundary length, as well as mechanical stability by forming a scaffold for the Ni network. Hence, for the optimal performance a thick layer of Ni-YSZ composite is required. On the contrary, the optimal oxygen electrode requires only very thin layer of the composite, otherwise the presence of YSZ is retarding the electrode’s performance.

Published: November 2023

AbstractIn Italy, rainfall represents the most common triggering factor for landslides; thus, many Italian Regional Departments of Civil Protection are setting up warning systems based on rainfall recordings. Common methods are mainly based on empirical relationships that provide the rainfall thresholds above which the occurrence of landslide phenomena is likely to be expected. In recent years, the use of machine learning approaches has gained popularity in landslide susceptibility analysis and prediction. To support the operational early warning system of Liguria Civil Protection Department for landslides hazard, we propose the implementation of a polynomial Kernel regularized least squares regression (KRLS) algorithm, for predicting the daily occurrence of shallow landslides in the five Alert Zones in Liguria (North Western Italy). The model provides an estimate of the number of landslides associated with the set of three different hydrological features, also used for the Hydrological Assessment procedure: the soil moisture, the accumulated precipitation over 12 h and the precipitation peak over 3 h. Results of the model are converted to an Alert Scenario of landslide occurrence, based on the magnitude of the expected event and identified according to the National and Regional legislation (Regional Civil Protection guidelines D.G.R. n. 1116, 23/12/2020). The performance of the predictive model (e.g. accuracy of 93%) is deemed satisfactory and the methodology is considered a valuable support to the operational early warning system of Liguria Civil Protection Department. The choice of predictive variables allows, in future development, the values obtained from historical data to be replaced by those obtained from meteorological forecast models, introducing the use of the developed model in the operational forecasting chain.
Modeling Interactions Between Multivariate Learner Characteristics and Interventions: a Person-Centered Approach

Published: November 2023

AbstractDemonstrating the differential effectiveness of instructional approaches for learners is difficult because learners differ on multiple dimensions. The present study tests a person-centered approach to investigating differential effectiveness, in this case of reading instruction. In N = 517 German third-grade students, latent profile analysis identified four subgroups that differed across multiple characteristics consistent with the simple view of reading: poor decoders, poor comprehenders, poor readers, and good readers. Over a school year, different instructional foci showed differential effectiveness for students in these different profiles. An instructional focus on vocabulary primarily benefited good readers at the expense of poor decoders and poor comprehenders, while a focus on advanced reading abilities benefitted poor comprehenders at the expense of poor decoders and good readers. These findings are in contrast to those obtained by multiple regression, which, focusing on only one learner characteristic at a time, would have suggested different and potentially misleading implications for instruction. This study provides initial evidence for the advantages of a person-centered approach to examining differential effectiveness.
An Exploratory Study of Students’ Perceptions on the Use of Animals in Medical and Veterinary Medical Undergraduate Education
Authors: Baptista Cláudia S. , Oliveira Pedro , Ribeiro Laura 
Published: November 2023

AbstractAnimals are frequently utilized as a teaching-learning tool in multiple educational settings. It is, therefore, important to understand what students think about this topic, in particular medical and veterinary students as “life caregivers” and competent people for a dynamic and responsible social intervention. In this context, this research aims to characterize and disseminate a set of issues related to animal welfare/wellbeing in higher education in the North of Portugal, particularly as regards the teaching of students of the Integrated Master in Medicine (MIM) and Veterinary Medicine (MIMV). After ethical approval, a survey was delivered on paper to 180 undergraduate MIM (n = 100) and MIMV (n = 80) students. After collecting 139 questionnaires partially or fully completed, with varying response rates for each question, it was concluded that most of the students consider that animal experimentation is ethically acceptable when the benefits balance the harms and assuming that refinement of animal procedures is warranted; they also agree to the establishment, maintenance and performance of animal procedures solely for educational purposes as a way of ensuring optimal acquisition of theoretical knowledge, attitudes and behaviors and technical skills. Nevertheless, it is the responsibility of teachers to explore and implement pedagogical methodologies thar are equally effective but more humane and compassionate towards sentient living beings.
Influence of elastic deformation of the blade on the flow field in the blade cascade
Authors: Vomáčko Václav , Šidlof Petr , Šimurda David , Pustka Martin 
Published: November 2023

AbstractFlutter of turbine and compressor blades represents a serious problem for designers of large turbomachines. In real machines, measurements of flutter conditions are hardly possible. Therefore, tests on linear blade cascades with movable blades play important role in investigations of flutter. In the current research, a simple blade cascade for controlled flutter testing was developed. The blades in this test rig undergo high-frequency oscillations which induce inertial forces. The influence of the elastic deformation of the blade on the flow field is studied in this work by means of experiments and numerical simulations. First, the computational and experimental modal analysis was done to obtain eigenfrequencies and modal damping. The deformed shape of the blade due to high-frequency oscillation was acquired by structural transient analysis. The influence of the elastic deformation on the flow field was then studied by CFD analysis for two incidence angles both for the deformed (elastic) and undeformed (idealized rigid) blade. Flow field was only very weakly distorted due to the blade elastic deformation. The total torque induced by aerodynamic and inertial forces was evaluated. The inertial loading is an order of magnitude larger than loading due to fluid flow.

Published: November 2023

Abstract
Background
Numerous observational epidemiological studies have reported a bidirectional relationship between periodontitis and urological cancers. However, the causal link between these two phenotypes remains uncertain. This study aimed to examine the bidirectional causal association between periodontitis and four types of urological tumors, specifically kidney cancer (KC), prostate cancer (PC), bladder cancer (BC), and testis cancer (TC).

Methods
Based on large-scale genome-wide association study (GWAS) data, we utilized the two-sample Mendelian randomization (MR) approach to evaluate causal relationships between periodontitis and urological cancers. Several MR methods covering various consistency assumptions were applied in this study, including contamination mixture and Robust Adjusted Profile Score to obtain robust results. Summary-level data of individuals with European ancestry were extracted from the UK Biobank, the Kaiser GERA cohorts, and the FinnGen consortium.

Results
Our findings revealed significant positive genetic correlations between periodontitis and kidney cancer (OR 1.287; 95% CI 1.04, 1.594; P = 0.020). We did not find a significant association of periodontitis on prostate cancer, bladder cancer, and testis cancer. In reverse MR, no significant results were observed supporting the effect of urologic cancers on periodontitis (all P > 0.05).

Conclusion
Our study provides the evidence of a potential causal relationship between periodontitis and kidney cancer. However, large-scale studies are warranted to confirm and elucidate the underlying mechanisms of this association.

AbstractLandfill leachate, which is a complicated organic sewage water, presents substantial dangers to human health and the environment if not properly handled. Electrochemical technology has arisen as a promising strategy for effectively mitigating contaminants in landfill leachate. In this comprehensive review, we explore various theoretical and practical aspects of methods for treating landfill leachate. This exploration includes examining their performance, mechanisms, applications, associated challenges, existing issues, and potential strategies for enhancement, particularly in terms of cost-effectiveness. In addition, this critique provides a comparative investigation between these treatment approaches and the utilization of diverse kinds of microbial fuel cells (MFCs) in terms of their effectiveness in treating landfill leachate and generating power. The examination of these technologies also extends to their use in diverse global contexts, providing insights into operational parameters and regional variations. This extensive assessment serves the primary goal of assisting researchers in understanding the optimal methods for treating landfill leachate and comparing them to different types of MFCs. It offers a valuable resource for the large-scale design and implementation of processes that ensure both the safe treatment of landfill leachate and the generation of electricity. The review not only provides an overview of the current state of landfill leachate treatment but also identifies key challenges and sets the stage for future research directions, ultimately contributing to more sustainable and effective solutions in the management of this critical environmental issue.
Drivers of divergent trends in tropospheric ozone hotspots in Spain, 2008–2019

AbstractThis study aimed to investigate the causes of contrasting ozone (O3) trends in Spanish O3 hotspots between 2008 and 2019, as documented in recent studies. The analysis involved data on key O3 precursors, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), among other species, along with meteorological parameters associated with O3. The dataset comprised ground-level and satellite observations, emissions inventory estimates, and meteorological reanalysis.The results suggest that the increasing O3 trends observed in the Madrid area were mostly due to major decreases in NOx emissions from the road transport sector in this urban VOC-limited environment, as well as variations in meteorological parameters conducive to O3 production. Conversely, the decreasing O3 trends in the Sevilla area likely resulted from a decrease in NOx emissions in a peculiar urban NOx-limited regime caused by substantial VOC contributions from a large upwind petrochemical area. Unchanged O3 concentrations in other NOx-limited hotspots may be attributed to the stagnation of emissions from sectors other than road transport, coupled with increased emissions from certain sectors, likely due to the economic recovery from the 2008 financial crisis, and the absence of meteorological variations favorable to O3 production.In this study, the parameters influencing O3 varied distinctively across the different hotspots, emphasizing the significance of adopting an independent regional/local approach for O3 mitigation planning. Overall, our findings provide valuable insights into the causes of contrasting O3 trends in different regions of Spain, which can be used as a basis for guiding future measures to mitigate O3 levels.
Towards the identification of the volatile organic compounds emitted by the coatings used in a car factory painting line

Published: November 2023

AbstractOne of the main reasons for the degradation of working conditions is the lack of air quality. It is known that indoor air contaminants pose a risk to both the human organism and the environment, which constitutes a challenge for employers and major industries. A car factory painting line is an evident example of a work location in which the employers must be especially aware and concerned with the employees' health. Since the coatings are the main VOCs-emitting source, this work studied the analytes emitted by four primers, 17 basecoats and one varnish used in a car factory of a world-renowned automotive brand, with gas chromatography-ion mobility spectrometry (GC-IMS), as a way of identifying all the coating-borne VOCs that can be emitted to the indoor air. The variability of the collected data was assessed, and the repeatability of the results proved the suitability of GC-IMS for this type of study. Among primers, inks and varnish, 45 VOCs were accurately identified using an exclusively developed database of compounds. The presence of the identified analytes in the composition of the coatings represents the potentiality of being emitted to the indoor air of the factory and, consequently, denotes their eventual toxicity for the employees of the painting line. These results represent a step forward in the assessment of the panting line work conditions, so eventual consequences to the employees’ health are theoretically discussed; nonetheless, further studies aim to examine air samples of the factory and evaluate the work conditions and actual consequences to the employees that must be developed.

Published: November 2023

AbstractSpinal cord injury (SCI) is a prevalent and significant injury to the central nervous system, resulting in severe consequences. This injury is characterized by motor, sensory, and excretory dysfunctions below the affected spinal segment. Transplantation of bone marrow mesenchymal stem cells (BMSCs) has emerged as a potential treatment for SCI. However, the low survival as well as the differentiation rates of BMSCs within the spinal cord microenvironment significantly limit their therapeutic efficiency. Tauroursodeoxycholic acid (TUDCA), an active ingredient found in bear bile, has demonstrated its neuroprotective, antioxidant, and antiapoptotic effects on SCI. Thus, the present study was aimed to study the possible benefits of combining TUDCA with BMSC transplantation using an animal model of SCI. The results showed that TUDCA significantly enhanced BMSC viability and reduced apoptosis (assessed by Annexin V-FITC, TUNEL, Bax, Bcl-2, and Caspase-3) as well as oxidative stress (assessed by ROS, GSH, SOD, and MDA) both in vitro and in vivo. Additionally, TUDCA accelerated tissue regeneration (assessed by HE, Nissl, MAP2, MBP, TUJ1, and GFAP) and improved functional recovery (assessed by BBB score) following BMSC transplantation in SCI. These effects were mediated via the Nrf-2 signaling pathway, as evidenced by the upregulation of Nrf-2, NQO-1, and HO-1 expression levels. Overall, these results indicate that TUDCA could serve as a valuable adjunct to BMSC transplantation therapy for SCI, potentially enhancing its therapeutic efficacy.
Multifaceted Roles of AFG3L2, a Mitochondrial ATPase in Relation to Neurological Disorders
Authors: Ghosh Dastidar Ranita , Banerjee Saradindu , Lal Piyush Behari , Ghosh Dastidar Somasish 
Published: November 2023

AbstractAFG3L2 is a zinc metalloprotease and an ATPase localized in an inner mitochondrial membrane involved in mitochondrial quality control of several nuclear- and mitochondrial-encoded proteins. Mutations in AFG3L2 lead to diseases like slow progressive ataxia, which is a neurological disorder. This review delineates the cellular functions of AFG3L2 and its dysfunction that leads to major clinical outcomes, which include spinocerebellar ataxia type 28, spastic ataxia type 5, and optic atrophy type 12. It summarizes all relevant AFG3L2 mutations associated with the clinical outcomes to understand the detailed mechanisms attributable to its structure-related multifaceted roles in proteostasis and quality control. We face early diagnostic challenges of ataxia and optic neuropathy due to asymptomatic parents and variable clinical manifestations due to heterozygosity/homozygosity of AFG3L2 mutations. This review intends to promote AFG3L2 as a putative prognostic or diagnostic marker.

Differentiation of self in adolescents: measurement invariance analysis across six Spanish-speaking countries
Authors: Gallego Ana , Schweer-Collins Maria L. , Osorio Alfonso , Rodríguez-González Martiño 
Published: November 2023

AbstractThis article examines the measurement equivalence of the Spanish Differentiation of Self Inventory for Adolescents (S-DSI-A) in adolescent populations across Spanish-speaking countries (N = 5,552), including Argentina, Chile, Ecuador, Mexico, Peru, and Spain. Within the Bowen family system theory, Differentiation of self is one of the most recognized constructs to systemic researchers and couple and family therapy practitioners, with implications in relationship adjustment or mental and physical health. The study uses multigroup confirmatory factor analysis (MGCFA) to test for configural, metric, and scalar invariance of the S-DSI-A across the six samples. The results indicate that the S-DSI-A demonstrates configural and metric invariance, but scalar invariance is not achieved. These findings have implications for cross-cultural research on differentiation of self and highlight the importance of considering measurement equivalence when comparing results across different populations. Specifically, our results suggest that the S-DSI-A reliably assesses the latent variables of Emotional Reactivity (ER) and Emotional Cutoff (EC) uniformly across Spanish-speaking nations, but the mean scores for the ER and EC lack cross-sample comparability.
