Background: Temporomandibular disorders (TMD) are a group of conditions affecting the jaw joint and the muscles that control jaw movement, can cause pain and discomfort in the jaw, face, and neck, and affect a person's ability to speak, chew, and swallow. Aim: The present study aims to specify the prevalence of temporomandibular joint disorder among dental students of Hawler Medical University. Method: The research conducted involved a group of 120 dental students, with an equal number of males and females from Hawler Medical University. The required data were collected by developing a particular questionnaire by modifying Fonseca's questionnaire. The study was performed during a period of one month from January to February. Visual Analogue Scale (VAS) was used to determine the severity of the pain and dysfunction in the participant's muscles. Results: More than 75% of the participants had no deviation. In 65.8% of the students, class 1 occlusion was observed. Trauma was observed in just 12.5% of the participants. Bite and bruxism habits were observed in 24.2% and 10% of the students respectively. Moreover, 30% of students had disturbed sleep. Severe TMJ pain was reported in 4.2% and 0.8% of females and males respectively. Conclusions: The occurrence of TMD among males was less than among females. Most of the participants had mild TMJ pain. There was a significant association between symptoms of TMD and para-functional habits. Keywords: Temporomandibular disorder, Temporomandibular joint, Fonseca's questionnaire.
ULTRASOUND-ASSISTED EXTRACTION OF NATURAL ANTIOXIDANTS FROM THE HAZELNUT SKIN: OPTIMIZATION AND COMPARISION WITH CONVENTIONAL METHOD
Authors: Özdemir Merve , Torun Mehmet
Published: March 2024

This study focused on extracting antioxidants from hazelnut skin, an industrial food waste, using two different methods: conventional extraction (CE) and ultrasound-assisted extraction (UAE). The Response Surface Methodology (RSM) has been utilized using the total phenolic content (TPC) and antioxidant capacity (AC) results as responses in optimizing both method conditions. The independent variables and their levels for the optimal experimental design were adjusted as follows: temperature (50-90°C), time (2-62 min), and loading capacity (5-15%) for CE; and temperature (25-50°C), time (1-30 min), loading capacity (5-15%), and ultrasonic amplitude (20-50%) for UAE. The optimum conditions were determined to be 90°C for 35 min with a 5% loading capacity for CE, and 50°C for 27 min with a 5% loading capacity and 50% amplitude for UAE. The TPC of the extracts were found to be 142.62 mg GAE/g and 129.69 mg GAE/g, while the AC values were 127.02 μmol TE/g and 116.00 μmol TE/g for CE and UAE methods, respectively. In conclusion, it has been demonstrated that hazelnut skin extracts obtained by optimizing CE and UAE methods can serve as natural antioxidant alternatives in food products and may hold significant potential for further applications.
Meat politics at the dinner table
Authors: Kennedy Emily , Baumann Shyon , Johnston Josée
Published: March 2024

Few food groups are subject to the same depth and scope of critique as meat. Yet little is known about how the Canadian public feels about meat production and consumption. In other jurisdictions, meat has been a politically polarizing topic; thus, we focus our analysis on political differences (and similarities) in orientations toward meat. In this paper, we draw on survey data collected on a quota sample of Canadians (n=2328) in order to address the following questions: to what extent do Canadians across the political spectrum agree that meat is a problem? Where is there overlap, and where is there disagreement? We find that, despite small but statistically significant differences across political ideology in Canadians’ meat-related attitudes, preferences, and practices, there is widespread agreement that meat is delicious, that it poses risks to health, and that many livestock production practices violate animal welfare ethics. The majority of Canadians would prefer to source meat that is locally-produced and raised on a small farm. These patterns illustrate high levels of discomfort with large-scale animal agriculture. This study fills an important gap in Canadian food studies by interrogating public perceptions of meat and identifying areas of political convergence and divergence on meat-related attitudes, preferences, and practices.

La consommation de protéines végétales présente plusieurs bénéfices sur le plan de la santé, de l’environnement et du développement du secteur agro-alimentaire. Malgré les avantages liés à la consommation de protéines végétales, la consommation de viande demeure souvent privilégiée. Cet article présente une revue de la littérature de presse visant à répertorier les interventions de promotion de la consommation de protéines végétales mises en place au Canada et dans des pays européens francophones. L’identification des documents s’est faite à partir de la banque de données Eureka pour les articles de journaux de quotidiens francophones en provenance du Canada et d’Europe et sur le moteur de recherche Google Actualités. Les articles publiés entre le 1er janvier 2015 et le 11 mai 2020 ont été retenus. Au total, 49 articles ont été inclus dans l’étude. Six types d’intervention ont été recensés (sensibilisation, conférences, législation, formation, partenariats/programmes de reconnaissance et offre d’un repas végétarien en restauration collective). L’intervention la plus populaire était l’offre de repas végétariens en restauration collective. Les barrières à l’implantation de ces interventions étaient souvent d’ordre organisationnel (ex : manque de temps), financier, matériel et culturel. Les forces des interventions impliquaient généralement le caractère participatif et volontaire du public cible et l’inclusion de diverses parties prenantes. Cette revue de la littérature de presse peut orienter les acteur.trices œuvrant dans le domaine de la nutrition afin de favoriser la mise en place d’actions de promotion de la consommation de protéines végétales.
Is cell-based meat a climate solution for Canada?
Authors: Katz-Rosene Ryan M
Published: March 2024

Interest and technological know-how in cell-based meat production has grown tremendously in recent years. The appeal is wide ranging, but two main drivers include: i) the possibility of producing edible meat without requiring the slaughter of sentient animals; and ii) the potential to significantly reduce the environmental impact of animal agriculture. Owing to these potential benefits, proponents have called for major government investments in cell-based meat to further develop the technology and help launch the industry. This article critically examines the environmental promise of cell-based meat, focussing specifically on its potential role in climate change mitigation, and specifically within the context of Canada’s agri-food sector. The analysis is founded upon a comparison of available life cycle greenhouse gas assessments of cell-based and conventional meat, supplemented with contextual data about the Canadian agri-food sector. Cell-based meat in Canada is found to have a likely carbon footprint similar in scale to poultry meat, pork, and beef from dairy cattle, though considerably lower than meat from beef cattle. Alongside these findings and additional contextual factors pertaining to Canada’s agri-food sector, the paper argues that cell-based meat is best understood as one tool among many which could potentially support greenhouse gas emissions reductions in domestic food production if supporting conditions are met, not a silver bullet climate solution obtained by fully replacing conventional meat.
Industrial meat in Canada, growth promoters and the struggle over international food standards
Authors: Smythe Elizabeth Ann
Published: March 2024

This article focuses on differing national regulations and standards regarding how meat for human consumption is produced and what is permissible in that production process. Attempts to harmonize these regulations at the global level to facilitate international trade have proven to be challenging. Such harmonization of regulations is especially important to countries exporting meat, such as Canada. The conflict at the global level reflects a range of differing trade interests and values about what meat is and how it should be produced. One area of disagreement is over the extent to which methods of growth promotion in animals using technology, particularly drugs, is acceptable and safe in terms of human consumption. Canada has taken the position that they are acceptable and safe.   Using two case studies of regulations related to the most recent set of beta agonist  drugs, ractopamine and zilpatrol, fed to livestock  to promote growth, I  examine the underlying sources of these conflicts and the extent to which they reflect the interests of various actors and the forms of power they may employ to try to shape global standards at the Codex Alimentarius and the view of what is acceptable meat.
Review of Ultra-processed people: Why we can’t stop eating food that isn’t food
Authors: Sumner Jennifer
Published: March 2024

Given the ubiquity of UPF, this book fills a vital gap in our knowledge. Thankfully, it is easy to read, combining research and interviews with personal anecdotes and amusing glimpses of van Tulleken family life. For those of us involved in food studies, the book adds an extra layer of urgency: van Tulleken proposes that UPF destroys the meaning of food—it becomes a technical substance without cultural or historical meaning. To avoid this outcome, let alone the millions of early deaths caused by poor diets that are increasingly made up of UPF, we need to better understand ultra-processed food and work to change the food system that allows these substances to flourish.
Laser Doppler Electrophoresis Applied to Colloidal Systems
Authors:   Department of Paper Science and Engineering, SUNY College of Environmental Science and Forestry, Goff J. , Luner P. ,   Department of Paper Science and Engineering, SUNY College of Environmental Science and Forestry
Published: March 2024

LASER Doppler Electrophoresis (LDE) has appeared recently as an alternative to classical methods of electrophoresis in the study of colloid systems.⁽¹-²⁾ In microelectrophoresis, individual particles are tracked under a microscope, while in LDE the counting of particles of various mobilities is performed automatically by means of optical processes. LDE provides a less time consuming and inherently more objective method than microelectrophoresis for analysing the mobility distribution of a system of particles. LDE may also have advantages over other classical electrophoretic methods in many cases. Moving boundary electrophoresis is useful for small particles or macromolecules, whereas mass transport electrophoresis is more suited to concentrated suspensions. LDE is applicable to reasonably dilute systems of particles which range in size from molecular dimensions to micrometers. The LDE system described here is designed to study particles in the upper part of this range.

The most widely used synthetic additives to improve drainage and fines retention during the formation of the fibrous mat are cationic polymers. These polymers are also frequently used to improve paper wet strength and internal bonding.(¹) Their wide applicability is based on their preferential adsorption onto the anionic fibres and fines.

Material Losses During Defibration and Beating of High-Yield Pulps
Authors:   The Finnish Pulp and Paper Research Institute, Helsinki, Finland, Levlin J. E. , Nordman L. ,   The Finnish Pulp and Paper Research Institute, Helsinki, Finland
Published: March 2024

One of the problems arising in the utilisation of high-yield pulps in papermaking is their tendency to produce various kinds of dissolved matter during mechanical treatment. One result of this is that the amount of paper producible from a given amount of wood is less than that which is calculated from the pulping yield. Moreover, the hazard element of the effluent from the environment aspect is increased. The literature contains little discussion of this problem, although Sjbström et al. have observed the dissolution of xylan from birch pulps of both normal and high-yield. ⁽¹,²⁾ Within the framework of a project concerning the optimisation of the defibration and beating of high-yield pulps a study has been made of the material losses that occur during these process stages. The results of this study are presented in the following.

Authors:   Paper Technology Department, Swedish Forest Products Research Laboratory, Stockholm, Sweden, Htun M. , de Ruvo A. ,   Paper Technology Department, Swedish Forest Products Research Laboratory, Stockholm, Sweden
Published: March 2024

The purpose of this work is to study the relationship between the drying stresses and internal stresses and the mechanical properties of paper. An apparatus was designed to measure the drying stresses, moisture content and surface temperature during the drying of paper. The internal stresses in paper were measured using the technique described by Kubdt et al.⁽¹⁻²⁾ The internal stress was found to be equal to the drying stress, independent of the structure of the sheet. The results also show that the drying stress developed during restrained drying correlates strongly with the mechanical properties of the paper when different types of fibre are compared under the same drying conditions.

Authors:   School of Chemistry, University of Bristol, Everett D. H. , Haynes J. M. ,   School of Chemistry, University of Bristol, Miller R. J. L. ,   School of Chemistry, University of Bristol
Published: March 2024

A simple gravimetric technique for determination of the rate of capillary imbibition of wetting liquids by porous solids is described, and illustrated with results obtained with a wide variety of liquids on a range of glass-fibre filter papers. Application of the familiar Washburn equation to the results yields an ‘imbibition equivalent’ pore size. Although, in the case of fibrous materials, it may be difficult to relate this to any real geometrical property, it nevertheless provides a practically useful description of the materials’ behaviour. The effects of prewetting on subsequent imbibition are explored.
The Effect of Moisture and Moisture Gradients on the Calendering of Paper
Authors:   Swedish Forest Products Research Laboratory, Stockholm, Sweden, Lyne M. B.
Published: March 2024

Machine calendering at conventional temperatures and line pressures has been compared with calendering at elevated temperatures, and calendering with an induced z-directional gradient in web moisture content . Print uniformity and web strengths are considerably improved by the latter calendering method, while rub off, set off, and print through remain at normal levels. A moisture gradient is established by calendering the paper web before applied moisture has time to wet the paper’s surface. Study of the wetting time shows that newsprint from thermomechanical pulp wets faster than stone groundwood newsprint, that wetting time is decreased when web moisture content is increased, and that pulp drying history is particularly important-papers from bale pulps exhibiting wetting times orders of magnitude greater than those from slush pulps. The absorption of mineral oil has been measured for papers calendered under different conditions . The studies show that calendering, and moisture gradient calendering in particular, slows the rate of oil absorption-while increasing web moisture content increases the absorption rate.

The various modes in which ordinary and modified cellulose fibres and surface modified cellulose microfibrils can interact with water are reviewed. The hydrogel state of fibres can be extruded and dried to form a continuous oriented strand: ‘one dimensional paper’. A colloidal suspension of surface modified cellulose microfibrils can be converted into a paracrystalline gel which exhibits birefringent domains and responds to extrusion through a cylindrical orifice to yield a continuous fibre whose density and x-ray diagram are characteristic of cellulose: ‘reconstituted native cellulose’. The mechanical properties of these two novel materials are reported. The mechanism of wet strength development in ‘one-dimensional paper’ which had been encapsulated with nascent polyethylene was studied. The polyethylene was confined to the exterior of the substrate and while it does not prevent fibre wetting and swelling the rate of wetting is considerably slowed. As a result, disruption of interfibre bonds is incomplete.

The Fundamental Problem in Recycling
Authors:   Paper Science, UMIST, Howarth P.
Published: March 2024

From a review of the literature and our own work, it appears that the problem requiring most urgent attention is the nature of secondary fibres themselves. It is shown that the essential difference between secondary and virgin fibres is their bondability and that this depends on the papermaking process by which the secondary fibres were generated. Mention is made of some treatments which go some way towards restoring the strength of sheets containing recycled fibre.

This paper is intended to summarise and follow up the papers presented at the Spring Conference of the B.P. and B.M.A. Technical Section in London in 1973 and the Eucepa Symposium in Bratislava in 1976. In 1968 the Fibre Institute of the Netherlands Organisation for Applied Scientific Research (TNO) initiated, in close co-operation with the Research Association of the Netherlands Paper Industry, a programme to promote the use of waste paper. This programme, which is still in progress, covers: 1. An overall comparison of mills which use clean and/or mixed waste paper. 2. Pulping, deflaking, cleaning, dispersing, de-inking and bleaching. 3. Treatment of sludges. 4. An analysis of raw materials losses. The studies are based mainly on comparisons of recycling equipments installed in Dutch paper and board mills. Special trials were made using the pilot plants of paper machine manufacturers.

Verbalisation of emotions in Ukrainian online media
Authors: Kushnir Oksana , Bila Nataliya , Medynska Olesia , Synorub Halyna
Published: March 2024

The relevance of the research is determined by the tendency of modern media discourse towards emotionality, evaluativeness, the importance of emotional language means the process of perceiving a journalistic text. Undeniable today is the growing popularity of digital media, which emphasizes the need to learn the language of emotions in the online environment. The subject of studies is language techniques and means of emotional expression in the texts of national news resources "Ukrainska Pravda" and "Dzerkalo Tyzhnia". The study aims to monitor and systematize the most common verbal markers of emotionality in online publications, to highlight the dominant connotative emotional language units in the context of the analyzed topics. The research methodology includes a complex of general scientific methods: conceptual analysis, content analysis, induction, analysis and synthesis, comparison, systematization an classification. The novelty of intelligence lies in typology language means and methods of expressing the emotional spectrum in online texts. As a result of the research, it was found that an important component of the media text is the audience's emotional reaction to it. Emotions are verbalized with the help of emotives i.e. language units of different levels (lexical, morphological, syntactic, stylistic). The content analysis of the all-Ukrainian online editions "Dzerkalo Tyzhnia" and "Ukrainska Pravda" from September 2020 to March 2021 showed the dominance of emotions with a negative connotation, corresponding to the emotions and experiences of journalists and recipients regarding conflict i.e. sensitive topics (Covid-19, violation of human rights and freedoms, violence, corruption). Metaphors and epithets, foreign vocabulary, qualitatively evaluative adjectives and idioms, subjective modal syntactic constructions with evaluative semantics, colloquial and colloquial vocabulary, neologisms are most often used. Emotionally expressive means demonstrate the dominance of a pejorative construction of reality, cause a predicted emotional effect in the audience and tend to model the language picture of modern media texts in the online space.
Definitions and assessments of recovery from gambling disorder: A scoping review
Authors: Mansueto Agathe , Challet-Bouju Gaëlle , Hardouin Jean-Benoit , Grall-Bronnec Marie
Published: March 2024

Background and aims

While the concept of recovery is receiving increasing attention in the context of gambling disorder (GD), no consensus has yet been reached regarding its definition. This scoping review aims to map the literature on GD recovery, identify gaps, and provide insights for a more holistic and patient-centred perspective.

Methods

A systematic search of three databases was conducted (PubMed, PsycINFO, and ScienceDirect). Based on the method by which the results of these studies were produced, the studies included were sorted into four categories (quantitative, instrument validation, qualitative, and mixed studies) and subsequently examined using conceptual analysis.

Results

One hundred thirteen articles were included in this research after the screening process. In the quantitative and instrument validation studies, recovery was defined or operationalized in terms of abstinence, the absence of a GD diagnosis, or mild GD severity, or by reference to treatment outcomes or controlled gambling. A meta-synthesis of the results of the qualitative studies revealed four core features of recovery (insight, empowerment and commitment, wellbeing enhancement, and reconsideration of the issue of relapse).

Discussion

Discrepancies in definitions, outcomes, and variables used were evident across studies. Additionally, the quantitative and standardized approaches employed in most studies exhibited severe limitations with regard to defining recovery from the subjective and multidimensional perspectives of people recovering from GD.

Conclusions

This lack of definitional clarity emphasizes the necessity for further qualitative research. This research should encompass multiple stakeholder perspectives to develop a working definition promoting recovery from a holistic, patient-centred, and tailored approach.
Ketamine and epigenetic processes in depression, intersection between serotonergic and glutamatergic pathways
Authors: Nepton Arghavan , Farahani Hesam , Williams Monnica T. , Booij Linda , Faber Sonya C.
Published: March 2024

Background

Hypotheses surrounding the etiology of depressive disorders encompass a wide range of biological changes that can occur in a depressed individual, from gene variations to epigenetic modifications and not only serotonergic mechanisms. Once again, the therapy response of the patient to antidepressants is connected to modifications in the epigenetic regulation of genes within the serotonergic system. The persistence of depressive symptoms points to the possibility that stable molecular adaptations in the brain, particularly at the epigenetic level, may be involved.

Methods

Narrative review to first, discuss the historical evidence behind how serotonin (5-hydroxytryptamine, 5-HT) signaling and its associated actors are involved in various biological processes and second, examine the role of ketamine as one of the newer treatments for depression.

Results

There is increasing evidence that responses to psychotherapy for mood disorders are correlated with epigenetic alterations. Although therapy response appears to be associated with epigenetic changes in genes regulating the serotonergic system, there are multiple lines of research that provide additional data implicating epigenetic alterations in the glutamatergic system. Also, the epigenetic regulation of target genes along the HPA axis are becoming more intriguing in linking mood disorders with environmental stressors, and warrant a closer look. Recent research suggests that ketamine's antidepressant effects may be linked to epigenetic alterations. Considering the multiple studies linking BDNF with depression, further exploration of its relation with ketamine in the context of epigenetic signaling is warranted.

Conclusion

Understanding how and to what extent epigenetic mechanisms change gene expression and how these changes are influenced by environmental stressors may eventually allow mental health professionals to better understand the biological basis of depression as well as to gauge the efficacy, onset, durability and duration of therapies to treat mood disorders. Moreover, understanding the relation between serotonergic neurotransmission and epigenetic mechanisms of how these may be modified by ketamine should lead us to a greater knowledge of their therapeutic potential.
Influence of solvent quality on the swelling and shear modulus of polymer gels chemically cross-linked in solution
Authors: Douglas Jack F. , Horkay Ferenc
Published: March 2024

The effect of temperature (T) is studied on the swelling of model poly(vinyl acetate) (PVAc) gels in isopropyl alcohol. The theta temperature Θ of these gels, at which the second osmotic virial coefficient A2 vanishes, is close to that of the corresponding high molecular mass polymer solution without cross-links so that solvent quality may be defined in the same way as the corresponding precursor polymer solution. We quantified the swelling and deswelling of PVAc gels relative to their size at the theta temperature, and also determined the effect of T on the shear modulus of these gels. It was found that both swelling and deswelling data could be reduced to a universal scaling equation of the same general form as derived from renormalization group (RG) theory for flexible linear polymer chains in solutions.

Graphical abstract

Variaton of the volumetric swelling factor as a function of the reduced temperature for PVAc gels swollen in isopropyl alcohol.

Image Warping and Its Application for Data Augmentation when Training Deep Neural Networks
Authors: Sirota Alexander , Akimov Aleksei , Otyrba Rostislav
Published: March 2024

The paper focuses on the improvement of the quality of learning for deep neural networks for a small data set in a classification task. One of the possible approaches to improve the quality of learning is researched which is based on the use of data augmentation (artificial reproduction of the data set) by image warping. The presented mathematical model and fast algorithm for warping make it possible to transform the original image while preserving its structural basis. The proposed algorithm is used to augment image data sets containing a small number of training samples. The augmentation consists of two stages including horizontal mirroring and warping of each of the samples. The effectiveness of such augmentation is tested through the training of neural networks of various types: convolutional neural networks (CNN) of a standard architecture and deep residual networks (DRN). A specific feature of the implemented approach for the solution of the problem under consideration consists in the refusal to use pre-trained neural networks with a large number of layers as well as further transfer learning, since their application incurs costs in terms of the computational resources. The paper shows that the efficiency of image classification when implementing the proposed method of augmenting training data on small and medium-sized data sets increases to statistically significant values of the metric used.

Published: March 2024

Despite being extensively used in numerous uses, precise and effective human activity identification continues to be an interesting research issue in the area of vision for computers. Currently, a lot of investigation is being done on themes like pedestrian activity recognition and ways to recognize people's movements employing depth data, 3D skeletal data, still picture data, or strategies that utilize spatiotemporal interest points. This study aims to investigate and evaluate DL approaches for detecting human activity in video. The focus has been on multiple structures for detecting human activities that use DL as their primary strategy. Based on the application, including identifying faces, emotion identification, action identification, and anomaly identification, the human occurrence forecasts are divided into four different subcategories. The literature has been carried several research based on these recognitions for predicting human behavior and activity for video surveillance applications. The state of the art of four different applications' DL techniques is contrasted. This paper also presents the application areas, scientific issues, and potential goals in the field of DL-based human behavior and activity recognition/detection.
Dental versus zygomatic implants in the treatment of maxillectomy: a finite element analysis
Authors: Leblebicioğlu Kurtuluş İkbal , Kilic Duygu , Kilic Kerem
Published: March 2024

Purpose

This study analyzed the stress distributions on zygomatic and dental implants placed in the zygomatic bone, supporting bones, and superstructures under occlusal loads after maxillary reconstruction with obturator prostheses.

Materials and Methods

12 scenarios of three-dimensional finite element models were constructed based on computed tomography scans of a patient who had hemimaxillectomy. Two obturator prostheses were analyzed for each model. A total force of 600 N was applied from the palatal to buccal bones at an angle of 45°. The maximum and minimum principal stress values for bone and also the von Misses stress values for dental implants and prostheses were calculated.

Results

When zygomatic implants were applied to the defect area, the maximum principal stresses were similar in intensity to the other models; however, the minimum principal stress values were higher than in scenarios without zygomatic implants. In models that used zygomatic implants in the defect area, von Misses stress levels were significantly higher in zygomatic implants than in dental implants. In scenarios where the prosthesis was supported by tissue in the non-defect area, the maximum and minimum principal stress values on cortical bone were higher than in scenarios where implants were applied to both defect and non-defect areas.

Conclusions

In patients who lack an alveolar crest after maxillectomy, reduced stress on the zygomatic bone is expected if a custom bar-retained prosthesis is placed on the dental implant. The stress was higher on zygomatic implants without alveolar crest support than on dental implants.

The paper presents experimentally obtained results on the long-term stability tests of the solid electrolyte amperometric sensor output signal during the operation in the O2 + N2 gas mixtures. These data prove the stability and reproducibility of the output signal when measuring the oxygen concentration in air for 8000 hours. The output signal variation during the tests did not exceed ± 2 %. We performed four heating / cooling cycles of different durations, which did not influence either sensor integrity or operation characteristics. The structure of the solid electrolyte sensor and the solid electrolyte/electrode interfacial layer remained unchanged during the tests.

The work is aimed at studying the effect of mechanical activation on the structure and electrical conductivity of the NaClO4 – and KClO4 – basedcomposites. Based on the result of the analysis of the DSC curves of the (1–x) NaClO4 – x Al2O3 and (1–x) KClO4 – x Al2O3 composites measured while heating and cooling the samples, it was established that the enthalpy of phase transitions in them decreased with an increase in the concentration of the nanosized dopant. A complication of all active vibrational contours corresponding to internal vibrations of the molecular anion in the composites with increasing Al2O3 concentration and a shift of the band of the fully symmetric stretching vibration v1 (A) to a low-frequency region was revealed by Raman spectroscopy. Based on electrochemical impedance spectroscopy data, it was determined that for the 0.4NaClO4 – 0.6Al2O3 system subjected to mechanoactivation, the values of specific ionic conductivity increased by two orders of magnitude as compared to that of pure NaClO4, while for the 0.4KClO4 – 0.6Al2O3 system, the values of specific ionic conductivity increased by three orders of magnitude as compared to the initial salt at T = 320 °C.
Mistakes in Language Policy as a Factor in the Collapse of the Soviet Union
Authors: Juan Liu
Published: March 2024

This article analyses the evolution of language policy in the former Soviet Union with reference to documentary sources and its relationship with national policy and the Constitution. The rapid changes in the national policy of the USSR, starting with the idea of full equality of all nations and the right to self-determination, with subsequent changes towards the rapprochement of peoples, influenced the language policy, which evolved from multilingualism to bilingualism with an emphasis on the Russian language. It is important to note that the Russian language did not have a clear legal status in the USSR Constitution, unlike the national languages, which were enshrined in the constitutions and language laws of the Soviet republics. The Russian language mainly spread through administrative decrees, which led to negative consequences such as manipulation of language issues by local nationalists and the emergence of national conflicts, and influenced the process of the collapse of the Soviet Union. Compared to the modern European Union, where English dominates over other languages, the USSR represented a different version of language coexistence and a different language policy. This emphasizes the importance of finding a balance between the unity and diversity of languages and cultures of nations. The lack of a clear position on multilingualism and manipulation of the national sense of language as an indicator of identity contributed to tensions and aroused all kinds of emotions, thus provoking conflicts on cultural and national grounds.
Wikipedia y los centros educativos de enseñanza superior de Portugal

Published: March 2024

Desde su fundación, Wikipedia se ha mostrado como uno de los recursos más visitados del mundo, y ha sido analizada tanto como herramienta comunicativa como educativa. Esta investigación se centra en estudiar su contenido en referencia a los centros educativos superiores de Portugal. También busca analizar los idiomas que mejor representan a estos centros educativos en Wikipedia y comprobar si el discurso de sus artículos ha sido creado gracias al trabajo colaborativo y libre. Para ello, se creó una clasificación con todas las instituciones superiores, se buscó en Wikidata si disponían de elemento y los idiomas de Wikipedia en los que estaban presentes. Se guardaron estos datos y se programó un bot para recoger las visitas que recibían, su tamaño, cantidad de fuentes en las que se basan, las ediciones que se han grabado en ellos y por quién han sido realizadas. Se encontraron 102 instituciones superiores, de las cuales 81 estaban presentes en Wikidata. De estas, 60 tenían artículo en Wikipedia en cualquiera de las lenguas activas de la enciclopedia, siendo la versión en portugués la de mayor número de artículos creados con 56. Las universidades de Coimbra, Lisboa y Porto se mostraron como las más importantes, demostrando que el discurso de sus artículos es fruto del trabajo colaborativo de muchos editores. El resto instituciones superiores mostraron unos datos muy diversos, en ocasiones con contenidos procedentes de cuentas con propósitos particulares, sobre todo en ciertas instituciones privadas. Por ello, se puede concluir que el contenido de los artículos de Wikipedia es muy variado, dependiendo de la importancia de las instituciones y el interés particular de los editores de la comunidad. En general, las instituciones de mayor prestigio están más vigiladas, tienen más editores a su cargo y su discurso es más variado que el de los centros más pequeños.
perception of clinical professionals on the use of telemedicine by videoconference in the Portuguese private health system
Authors: Woss Joana Lucilia
Published: March 2024

This article aims to discuss the use of telemedicine in doctor-patient communication in the consultations context and aims to assess the perception of clinical professionals from Portuguese private hospitals about the use of telemedicine by videoconferencing. We used the unified theory of acceptance and use of technology 2 (UTAUT 2) to reflect on the topic and analyze the research results. We applied deepened semi-structured interviews to nine doctors, from seven different specialties, from private hospitals, which provide consultations through videoconferencing, namely Hospital da Luz and Trofa Saúde. The interviews were conducted in May and June 2022. The participants referred to telemedicine as a complementary tool to face-to-face consultations, with occurrence limitations according to the medical specialty and pathology. We concluded that the tool, along with technological developments that support it, in the future will become part of medical consultations, and the high motivation of health professionals is necessary for the successful implementation of these tools. The contribution of this study is showing the relevance of the professionals' motivation for the adoption of videoconferencing technology tools.
Responsabilidad Social Corporativa en el Real Betis y el Sevilla FC: enfoques corporativos y percepción de los aficionados
Authors: Ginesta-Portet Xavier , Lobillo-Mora Gema , Menéndez-Signorini Jésica
Published: March 2024

Este artículo analiza la RSC del Real Betis y el Sevilla FC y la percepción que tienen sus aficionados de ella. Se despliegan cinco entrevistas en profundidad a directivos de ambos clubes y una encuesta no probabilística contestada por 105 aficionados béticos y 105 de sevillistas. Los resultados de esta investigación muestran que, mientras el Betis plantea una RSC de carácter medioambiental, que se vehicula a través del programa Forever Green, en el Sevilla FC es de tipo social. Los aficionados asumen los planteamientos de los clubes, que se pueden definir como posibles “agentes de cambio” en su comunidad, aunque se detectan posibles mejoras en los procesos de comunicación.
Evolución de la comunicación audiovisual móvil informativa en España
Authors: García-Torre Manuel , Formoso-Barro María Josefa , Videla-Rodríguez José-Juan
Published: March 2024

La comunicación móvil ha sido una de las grandes revoluciones a las que se han tenido que adaptar los medios de comunicación en la era de digital. La información es uno de los contenidos que toman protagonismo en las programaciones de los canales y por lo tanto en sus apps. El presente artículo profundiza en la evolución de las aplicaciones móviles para smartphone de las televisiones generalistas españolas durante el periodo 2012-2022 concretando este acercamiento en los contenidos informativos y en la interactividad. Se ha desarrollado una metodología mixta, cuantitativa y cualitativa. Dentro de la vertiente cuantitativa se ha realizado un análisis de contenido que ha permitido observar las diferentes estrategias en cuanto al tratamiento de la información en las televisiones objeto de estudio. Por ejemplo, RTVE apuesta de forma clara por la distribución de contenidos informativos en movilidad. Por otra parte, para Atresmedia y Mediaset la información no es prioritaria ya que centran su estrategia en movilidad, a excepción de LaSexta, en los contenidos de entretenimiento. En cuanto a la apuesta por la interactividad, su evolución ha ido en descenso debido a que algunas de las televisiones analizadas, hicieron en su día una apuesta clara por ofrecer herramientas interactivas creando aplicaciones concretas que la explotaban, pero a día de hoy están descatalogadas. En la actualidad, la información es un contenido secundario para las televisiones privadas y la interactividad se reduce a compartir contenido por redes sociales y correo electrónico siendo estas posibilidades muy poco interactivas.
