Declaration on the Common Language (Deklaracija o zajedničkom jeziku, 2017): Anti-nationalist Provocation, or a Reflection of Objective Reality?
Authors: Krejčí Pavel
Published: June 2024

The language policy of the states in which Serbo-Croatian was the official language at the time has not always been the same either in the historical plan or in the present. From the first half of the 19th century until the establishment of the Yugoslav state (1918), a part of the Serbian and Croatian elites was characterized by a search for ways to find a mutually acceptable standard for their common written language. This process then continued under changed political conditions after 1918, but without romantic notions, especially on the part of the Croatian political and professional community. The rejection of the sociolinguistic project of a common written language with the Serbs manifested itself first during the Second World War (1941–45), then in the period 1967–71, and finally in the new Croatian Constitution of 1990. Linguistic issues related to the specifics of the language of Montenegro and Bosnia and Herzegovina began to emerge in the late 1960s, but only came into full force after the break-up of the SFR Yugoslavia (1992). The four national communities using Serbo-Croatian (and then in a separate form Serbian, Croatian, Bosnian and Montenegrin) during the Yugoslav era generated a total of seven declaratory texts with different scope, content, accents and conclusions between 1967 and 2007. All of them, however, were united by their linguistic nationalism – from moderate and rather defensive to radical and offensive. The eighth was the Declaration on a Common Language (2017), another decade later, the nature of which contradicts many of the postulates proclaimed in previous declaratory texts. This approach has been described by many critics as a marginal effort to return to Serbo-Croatian or even as a provocation that contradicts the relevant constitutional articles and that threatens national independence. The authors of the Declaration, however, point out that their declaration does not mandate anything, does not oblige anyone, does not discriminate against anyone, but tries to point out the obvious shortcomings of the existing language policy in the post-Serbo-Croatian space, which lead to linguistic segregation in schools and other unusual and even defective manifestations caused by the alleged otherness of the four written languages mentioned above. At the same time, they offer a relatively simple and appropriate model of how to understand and interpret the linguistic situation in the territory of the former Serbo-Croatian language, e.g. in the university teaching of Slavic studies.
Stories of our Grandmothers: How Modern Ukrainian Women's Literature Deconstructs the Soviet Myth about the Great Patriotic War
Authors: Zhygun Snizhana
Published: June 2024

The article analyses how contemporary women’s literature deconstructs the Soviet myth of the Great Patriotic War under the influence of contemporary Russian aggression. This myth defined the narrative of World War II as a heroic sacrifice of the Soviet people. As a result, the diversity of experiences was suppressed and the memory of them was not formed. Since independence, Ukrainian culture has been restoring the gaps in history and memory, which has become especially important in the context of the ongoing war. Women’s literature participates in this process by focusing on women’s experiences, which are usually marginalized in the national-focused narrative. This study aims to identify the contribution of women’s literature to the process of decolonization. The object of the study is such women’s novels as The Museum of Abandoned Secrets by Oksana Zabuzhko (as a precursor to the modern treatment of the topic), Amadoka by Sofia Andruhovych, Because it Hurts by Yevgenia Senik, Eva’s Apples by Khrystyna Kotsira and Faride by Iren Rozdobudko. The study found that women’s literature most often addresses the topics of women combatants, deportations, and the Holocaust. In this way, the authors contribute to the process of returning to national history. At the same time, the study demonstrates the complex interaction of nationality and gender in contemporary women’s literature. As women’s literature also contradicts the traditional nationally oriented discourse, emphasizing female agency and appealing to multinational experience (except Ukrainian, Jewish, and Crimean Tatar). This understanding of the theme of the Second World War by contemporary Ukrainian women’s literature creates a context for the perception of the specifically female experience of the current war and resists attempts at ideological manipulation around women’s roles.
THE USE OF BORIC ACID AND ANTIMONY OXIDE AS AUXILIARY MINERALS WITH HUNTITE HYDROMAGNESITE TO IMPROVE FLAME RETARDANT PROPERTIES OF WOODDUST COMPOSITES
Authors: ATAY GÜL YILMAZ , BILGIÇ NURŞAH , JAAFAR MARIATTI
Published: June 2024

Boric acid, antimony oxide minerals and huntite hydromagnesite minerals were used as auxiliary minerals in wood composites to change their flammability features. Composite samples were prepared by using different ratios of sawdust, huntite, hydromagnesite, antimony and boric acid combinations. The obtained samples were characterized by scanning electron microscopy (SEM) analysis to determine the structural and morphological properties of the composites. Thermal behavior of the composites was determined by differential thermal analysis-thermogravimetry (DTA-TG). Tensile and three-point bending tests were performed to understand the mechanical properties. Finally, the flame retardant performance of the samples was observed according to UL94 vertical flammability tests. It was concluded that wood composites containing inorganic minerals gained resistance against fire, a good synergistic effect was obtained in different additive types
Biosynthesized Carbon-derived Nanomaterials as a Photocatalytic Solution for Sustainable Water Pollution Control
Authors: Kumar Ravi , Kaushal Shweta , Thakur Naveen , Kumar Kuldeep
Published: June 2024

Carbon nanomaterials are one of the most widely investigated nano-materials for the degradation of organic and inorganic pollutants like dyes and insecticides in an environmentally benign and that too in sustainable manner. The problems associated with the existing catalysts are related to their high band gap values and large particle sizes. In this review, the photocatalytic degradation of pollutants from industrial wastewater by using negligible amounts of carbon nanocatalysts has been covered as a solution to such types of problems. The photocatalytic activity of the carbon nanocomposites was reported to be affected by factors like particle size, nature of crystallinity, band gap, morphology and total surface area of the nanomaterials per unit mass. Despite various required optimizations, the carbon-containing nanomaterials such as carbon nanotubes, graphene, and metal oxide nanocomposites synthesized by using different methods have shown better photocatalytic activity as compared to others. This review article may open a new avenue to control water pollution efficiently and cost-effectively.

Turbulent Gas-rich Disks at High Redshift: Bars and Bulges in a Radial Shear Flow
Authors: Bland-Hawthorn Joss , Tepper-Garcia Thor , Agertz Oscar , Federrath Christoph
Published: June 2024

Recent observations of high-redshift galaxies (z ≲ 7) reveal that a substantial fraction have turbulent, gas-rich disks with well-ordered rotation and elevated levels of star formation. In some instances, disks show evidence of spiral arms, with bar-like structures. These remarkable observations have encouraged us to explore a new class of dynamically self-consistent models using our agama/Ramses hydrodynamic N-body simulation framework that mimic a plausible progenitor of the Milky Way at high redshift. We explore disk gas fractions of f
gas = 0%, 20%, 40%, 60%, 80%, and 100% and track the creation of stars and metals. The high gas surface densities encourage vigorous star formation, which in turn couples with the gas to drive turbulence. We explore three distinct histories: (i) there is no ongoing accretion and the gas is used up by the star formation, (ii) the star-forming gas is replenished by cooling in the hot halo gas, and (iii) in a companion paper, we revisit these models in the presence of a strong perturbing force. At low f
disk (≲0.3), where f
disk is the baryon mass fraction of the disk relative to dark matter within 2.2 R
disk, a bar does not form in a stellar disk; this remains true even when gas dominates the inner disk potential. For a dominant baryon disk (f
disk ≳ 0.5) at all gas fractions, the turbulent gas forms a strong radial shear flow that leads to an intermittent star-forming bar within about 500 Myr; turbulent gas speeds up the formation of bars compared to gas-free models. For f
gas ≲ 60%, all bars survive, but for higher gas fractions, the bar devolves into a central bulge after 1 Gyr. The star-forming bars are reminiscent of recent discoveries in high-redshift Atacama Large Millimeter/submillimeter Array observations of gaseous disks.
Comparison of Solar Wind Interaction with Mars and Earth: Energy Transfer
Authors: Zhang H. X. , Lu J. Y. , Wang M. , Zhou Y.
Published: June 2024

Using a global magnetohydrodynamics numerical simulation, this work compares the interaction of the solar wind with Mars and Earth from the perspective of energy transfer under north–south interplanetary magnetic fields (IMFs). Mars lacks a global dipole magnetic field like Earth’s and instead has a small-scale crustal magnetic field near highlands in the southern hemisphere. Unlike Earth’s magnetopause reconnection (at the subsolar point or tail under a southward IMF, or behind the cusp under a northward IMF), the reconnection of the Martian magnetic pileup boundary (MPB) occurs near solar zenith angle (SZA) ≈ 45° (SZA ≈ 30° and 60°) for a southward (northward) IMF, resulting in asymmetric energy transfer between the northern and southern hemispheres. The Martian outflow of mechanical energy appears near SZA ≈ 45° (SZA ≈ 30° and 60°) under a southward (northward) IMF, accompanied by an inflow due to the process of “solar wind pickup.” For energy transfer across the MPB, whether the IMF is northward or southward, the input of electromagnetic energy is twice as large as the input of mechanical energy, which is similar to Earth’s magnetopause for a southward IMF, but opposite to it for a northward IMF. The energy transfer rate of the MPB is slightly higher in a northward IMF than in a southward one, whereas the energy transfer rate of Earth’s magnetopause is far higher in a southward IMF than in a northward one.
Variation of the stable isotope niches of native amphibians in ponds invaded by the red swamp crayfish
Authors: Belouard Nadège , Petit Eric J. , Cucherousset Julien , Paillisson Jean-Marc
Published: June 2024

Relationships between native and invasive species can modify trophic interactions in food webs and the diet of native species, leading to substantial changes in their trophic niches. We quantified the stable isotope niche of native amphibians (two species of tadpoles and two species of newts) and the invasive red swamp crayfish (Procambarus clarkii) in 18 ponds of an area invaded for more than 30 years. We tested whether crayfish presence and abundance explained variation in the size and position of the amphibians’ stable isotope niches compared with proxies of pond resource availability and competition levels. Agile frog tadpoles (Rana dalmatina) had consistently low trophic positions, while tree frog tadpoles’ niches (Hyla arborea) showed signs of an opportunistic diet. Newts (palmate newt (Lissotriton helveticus) and marbled newt (Triturus marmoratus)) had high trophic positions consistent with a predatory diet. Crayfish showed a high level of trophic variability, but their trophic niche never overlapped with the trophic niche of amphibians. Amphibian niche size and position were associated with amphibian density and pond canopy cover rather than with crayfish presence or abundance. This study suggests limited changes in amphibian diets in the presence of red swamp crayfish in ponds compared with results from experimental studies, suggesting that complex environmental conditions and the long time since invasion might limit trophic interactions between these native and invasive species.

Background/Aims: There is limited knowledge regarding the management of duodenal subepithelial lesions (SELs) owing to a lack of understanding of their natural course. This study aimed to assess the natural course of asymptomatic duodenal SELs and provide management recommendations.Methods: Patients diagnosed with duodenal SELs and followed up for a minimum of 6 months were retrospectively investigated.Results: Among the 443,533 patients who underwent esophagogastroduodenoscopy between 2008 and 2020, duodenal SELs were identified in 0.39% (1,713 patients). Among them, 396 duodenal SELs were monitored for a median period of 72.5 months (interquartile range, 37.7–111.3 mo). Of them, 16 SELs (4.0%) showed substantial changes in size or morphology at a median follow-up of 35.1 months (interquartile range, 21.7–51.4 mo). Of these SELs with substantial changes, tissues of two SELs were acquired using endoscopic ultrasound-guided fine needle aspiration biopsy: one was a lipoma and the other was non-diagnostic. Three SELs were surgically or endoscopically removed; two were diagnosed as gastrointestinal stromal tumors, and one was a lipoma. An initial size of 20 mm or larger was associated with substantial changes during follow-up (p = 0.016).Conclusions: While the majority of duodenal SELs may not exhibit substantial interval changes, regular follow-up with endoscopy may be necessary for cases with an initial size of 20 mm or larger, considering a possibility of malignancy.
The Contingent Nursing Workforce during COVID-19: Implications for Policy and Administration
Authors: Longyear Robert , Puente James
Published: June 2024

COVID-19 exposed significant supply issues and operating challenges in hospital labor markets. Travel contingent workers, both local and out-of-state, are utilized by healthcare facilities to fill gaps in full-time staffing during periods of increased patient demand or labor shortages. Registered nurses (RNs), or travel nurses, are an essential component of this group. The increase in patient demand for nursing services related to COVID-19 has exacerbated existing RN labor challenges among full-time RN staff leading to an exponential increase in the national demand for contingent RN labor. Existing workplace issues and burnout have also contributed to increased attrition from hospital roles and from the nursing profession altogether leading to additional increased demand for labor from the contingent RN labor force over and above COVID-19 driven demand. Analyzing data from a major digital travel nursing job marketplace illustrates the significant increase in travel nursing pay rates and their relationship with COVID-19 infection rates. Median ICU travel nurse hourly pay increased 55.4% from 2019 to 2023 leading to unsustainable financial strain on hospitals. As health system leaders aim to re-build their nursing workforce following COVID-19, it is It is essential for public health professionals and policymakers to understand the labor market dynamics at play in these two distinct, but intertwined labor markets to implement evidence-based policy and administrative solutions.
Registered Nurses Leaving the Profession in the First Two Years
Authors: Tate Stephanie
Published: June 2024

Registered nurses are leaving the profession within the first two years of practice at rates as high as 33%. It has been suggested that nurses leave due to factors such as bullying by coworkers, inadequate educational preparation and/or orientation as a new hire, and more recently, the impact of the COVID-19 pandemic. Retention and work dissatisfaction remain key areas of study within nursing research. However, most studies consider intent to leave, versus studying those nurses who have actually left the profession. The purpose of this qualitative study was to identify the reasons that novice nurses have left their positions within this timeframe. The study included interviews with 17 registered nurses to examine reasons why they left the nursing profession and how they might have been retained. Themes that emerged from this study included Overworked, Family Obligations, Management, Not Completely Gone, and Additional Findings. The discussion of study findings describes potential interventions that may be helpful to retain nurses, such as self-scheduling with manager training and buy-in, and implications for future research.
Gouvernementalités de et par l’attente de la diaspora syrienne
Authors: Klaus Enrique
Published: June 2024

Fondé sur un travail d’enquête ethnographique, cet article porte sur l’administration consulaire syrienne à Istanbul. Il est plus précisément consacré à l’analyse du lien produit par le consulat et qui subsiste par-delà l’exil entre les Syriens exilés de guerre et le régime qui les a acculés au départ. À travers l’analyse des espaces de la rencontre administrative et des multiples régimes de temporalité dans lesquels elle s’insère, l’article interroge la politique du régime assadien en direction des exilés en explorant une hypothèse double. D’une part, le pouvoir du régime s’exercerait par l’emprise de ce dernier sur le temps des administrés au travers d’une politique de l’attente. D’autre part, l’État syrien mettrait en œuvre une politique par l’attente, destinée à assujettir ces mêmes administrés.

Glasbeno in plesno delovanje žensk s priseljenskim ozadjem v Sloveniji
Authors: Bejtullahu Alma
Published: June 2024

While many people have a formed opinion of them, few really know the musical and dance creativity of women shaped by the immigrant experience. Alma Bejtullahu's book (' Musical And Dance Practices Of Women With Immigrant Background') sheds light on part of their rich cultural and artistic activities within the cultural societiens, namely the diverse approaches to music and dance practices through which women express their immigrant and ethnic backgrounds in the Western Balkan countries. Women of different ages are involved in this amateur and socially engaged activity, which is rooted in a variety of personal circumstances and experiences. In the societies, they often learn the standardised performance practices that they use to recreate the musical traditions of their countries of origin. In addition to the above, the book also examines the musical practices of women artists who work as individuals, outside the confines of cultural societies, and who are predominantly professional musicians. Their distinctive feature is an individualised creative attitude towards the music of the Western Balkans, which they interpret in their own unique ways, often collaborating with musicians of other ethnicities. In all these processes of re-creation, women play a key role, not only as performers, but also as organizers, which enables them to decide about their practices and thus change the levers of power in their communities and in the society at large.

Ne pas réveiller un serpent qui dort : une campagne d’éducation anti-xénophobie dans les townships du Cap (Afrique du Sud)
Authors: Fortaillier Léo
Published: June 2024

Depuis la fin de l’apartheid en 1994, l’Afrique du Sud attire de nombreux exilés africains qui fuient les conflits ou la pauvreté. Souvent désignés comme boucs émissaires dans un pays où persistent de fortes inégalités, ils sont régulièrement la cible d’attaques dans les townships. Celles-ci prennent une forme particulièrement violente en 2008, ce qui pousse des ONG « de service » pour migrants à organiser des actions de sensibilisation aux questions migratoires à l’attention des habitants des townships.Pour comprendre leur approche, cet article se focalise sur un document de travail – une feuille de route – utilisée par l’Agency for Refugee Education, Skills Training and Advocacy (ARESTA) dans le cadre de sa campagne d’éducation anti-xénophobe. L’analyse se concentre sur la vision institutionnelle que cette feuille de route véhicule, autrement dit le regard que portent ARESTA et son principal bailleur, le Haut-Commissariat aux réfugiés (HCR), sur la migration et la xénophobie. L’article revient également sur l’interprétation particulière que fait un employé d’ARESTA de ce document et de cette vision lorsqu’il intervient dans des écoles pour s’adresser à un public adolescent. Pour cet employé, il faut pouvoir parler de migration et de xénophobie sans « réveiller un serpent qui dort », c’est-à-dire sans susciter le sentiment xénophobe qu’ARESTA veut combattre. S’il doit parfois bricoler le « discours politique dépolitisé » (selon l’expression de Bourdieu) du HCR et d’ARESTA pour l’adapter à cet objectif et à son audience, il évite les questions sensibles et contourne les difficultés en dépolitisant le sujet. Les arguments universels qu’il mobilise, qui visent à être consensuels à tout prix, empêchent la construction d’un « nous » qui remettrait en cause la distinction citoyens/étrangers au fondement de la xénophobie.
Vestígios da solidariedade nos centros de treino dos movimentos de libertação em Angola
Authors: Pearce Justin
Published: June 2024

Desde meados dos anos 1970 até finais dos 1980, Angola acolheu guerrilheiros que lutavam pela libertação de outros estados da África Austral, com a participação de conselheiros cubanos e soviéticos. Os estudos sobre as lutas de libertação na era da Guerra Fria passaram de narrativas centradas na nação a perspectivas globais e locais. Nesta transformação, os encontros internacionais que tiveram lugar no âmbito dessas lutas atraíram a atenção dos historiadores. Em particular, o campo de treino militar passou a ser visto como um ambiente que alimentava relações sociais e políticas específicas, mas pouca evidência física desses campos permanece. Este artigo é baseado em fotografias tiradas em Camalundu e Caculama, dois locais na província de Malanje, em Angola, onde os restos desses campos ainda são visíveis. Em Camalundu, a arquitectura colonial portuguesa aponta para a função original do local, enquanto slogans em inglês e espanhol, referenciando a história sul-africana e movimentos revolucionários globais, falam da presença de cubanos e sul-africanos e fornecem indicações de como estes viram seu próprio papel no contexto da política internacional da época. Em Caculama a natureza isolada e defensiva do local e das suas instalações evidencia o papel sul-africano em relação ao pensamento estratégico angolano. As fotografias complementam as memórias e testemunhos orais existentes sobre a política do exílio e sobre a vida nos campos, fornecendo evidências de diferentes tipos sobre a presença dos combatentes da libertação e suas relações com o mundo em geral. Também servem para preservar um registo histórico visual e tangível que, na ausência de medidas de preservação, está em perigo de decadência e de ficar irreconhecível.
Passeur d’images : regards d’un photographe amateur sur la société marocaine, la collection de Désiré Sic, 1912-1934
Authors: Américi Laurence , Dusserre Aurélia
Published: June 2024

Cet article présente un fonds photographique amateur, dont une grande partie porte sur le Maroc colonial, de 1912 aux années 1930. Pour constituer ces photographies en sources, la démarche consiste tout d’abord à chercher à faire l’histoire de la collection de ces quatre mille photographies : comment un tel ensemble de plaques de verre parvient-il jusqu’aux historiens ? Quelles sont la part et l’intention de l’auteur des images ? Quel statut celles-ci reçoivent-elles au fil des décennies ? Nous tentons de restituer la démarche de ce sous-officier de l’armée française qui photographie le Maroc pendant deux décennies et s’emploie ensuite à conserver ces images pendant tout le reste de son existence, au sein de l’intimité familiale. Il s’agit dès lors d’étudier la production, la circulation et la conservation de ces photographies produites par un acteur modeste, en dehors de toute célébrité, de toute reconnaissance culturelle, politique ou sociale. Source discrète, longtemps ignorée, oubliée, ces images ont fait l’objet d’une archéologie familiale, qui détermine l’accès des chercheurs.Que voyons-nous par ces photographies réalisées sans objectif affiché de documentation ? Comment peut-on inscrire un tel fonds dans l’imagerie coloniale ? Le parcours du photographe amateur se construit au long sa carrière de sous-officier puis d’officier du génie dans l’armée française, pendant ses séjours au Maroc, de part et d’autre de la Grande Guerre. La temporalité des prises de vues et celle de la constitution de la collection sont à interroger, afin de cerner le contexte des photographies parvenues jusqu’à nous. La démarche de recherche tente alors de s’attacher aux indices qui témoignent de l’intentionnalité dans la constitution de ce fonds, postulant que, même si elle relève de l’intime et n’est jamais formulée, la démarche de conservation n’est en rien laissée au hasard.Aussi, le fonds des photographies de Désiré Sic, qu’elles soient prises au Maroc ou en France, peut-il s’inscrire dans l’histoire de la pratique amateur des débuts du xxe siècle et permet d’interroger la nature de cette pratique : simple usage d’un outil technique banalisé ou production culturelle à valeur originale, de la part d’un autodidacte ?Ce sont alors les indices de la culture visuelle de cet acteur modeste qu’il convient de rassembler. Comment s’approprie-t-il le répertoire orientaliste ? Comment use-t-il des règles communes aux photographes excursionnistes ? Cette approche conduit à interroger les spécificités du regard orientaliste et colonial, en les confrontant aux autres motifs récurrents qui imprègnent ces photographies d’amateur.Ainsi, est-il possible d’approcher la dimension documentaire de ces fonds quant aux instantanés de la colonisation, la question du pouvoir étant récurrente malgré la position modeste de l’auteur dans la hiérarchie militaire et dans la société. C’est au croisement des regards, que ce fonds invite, sans isoler l’expérience coloniale d’une culture transnationale.
Physiological and biomechanical analyses of a 200 m all-out front crawl
Authors: Franken Marcos , Jesus Kelly de , Miranda Vitória , Jesus Karla de
Published: June 2024

This study aimed to analyze the effort effects of laps on general stroke kinematics and associate the peak oxygen uptake (V̇O2peak) with all-out 200-m front crawl time. Fourteen regional-level swimmers (age 16.14 ± 2.68 years; height 1.65 ± 0.08 m; body mass 58.17 ± 7.76 kg) performed an all-out 200 m front crawl. Oxygen consumption (V̇O2) was measured post-all-out 200 m trial to assess physiological variables and stroke mechanics was assessed based on the time to perform 10 m and time to perform three complete arm stroke cycles. The 1st lap had a higher stroke rate (SR) than the 3rd lap (44.73 vs. 40.82 cycles⋅min-1; p = 0.04). The 1st lap showed a higher mean swimming speed (SS) than the following laps (1.45 ± 0.10 vs. 1.35 ± 0.11 vs. 1.30 ± 0.11 vs. 1.28 ± 0.13 m⋅s-1; p < 0.01) and the 2nd was greater than the 4th lap (p < 0.05). The swimming index (SI) was smaller and greater in the 3rd lap compared to the 1st and 4th laps (2.60 ± 0.65 vs. 2.97 ± 0.71 vs. 2.43 ± 0.50 m2⋅s-1⋅cycles-1), respectively. There was moderate and inverse coefficient of correlation between the V̇O2peak and 200-m time (rho = -0.653; p < 0.05). Our findings suggest that V̇O2peak values should be assessed in post 200-m all-out effort due to the strong shared variance with performance and a pacing strategy should be adopted during the race to avoid detrimental effects of fatigue.

Published: June 2024

This study assessed the influence of different insertion angles and depths on the stress distribution in implants and prosthetic components subjected to axial and oblique loading. The study followed the Checklist for Reporting In-vitro Studies (CRIS) recommendations. The implant was placed in the region of element 36, according to the following models: M1 (0 mm / 0°); M2 (0 mm / 17°); M3 (0 mm / 30°); M4 (2 mm / 0°); M5 (2 mm / 17°); M6 (2 mm / 30°). All models were subjected to axial and oblique loading with an intensity of 100 N. Stress was assessed according to the Rankine and Von Mises criteria and analyzed qualitatively and quantitatively. There were minimal differences between the implants placed at bone crest height and 2 mm below it. In the external portion of the intermediates, the models angled at 30° presented higher stress concentrations under both loads. The internal part of the intermediates and the crown screw showed higher peaks as the implant angles increased. The models with inclined implants positioned below the bone crest were slightly compromised. As for the other models, the results were far from the yield point of the analyzed materials, indicating a long service life of implants and their prosthetic components in the assessed conditions.
Cold chain logistics: the pathways of vaccines and thermolabile medicines to patients in municipal primary care
Authors: Ferman Patricia Maria Flores , Gonçalves Regina Aparecida Correia , Oliveira Arildo José Braz de
Published: June 2024

For the quality assurance of thermolabile medicines and vaccines, it is imperative that all stages of the cold chain are satisfied. The aim of this study was to analyze the temperature of boxes containing medications and vaccines on routes between the Regional Health Facility of Apucarana, Paraná State, to the cities it serves, using the parameters of the Cold Network Manual. The temperature within the boxes remained within the recommended range (2 to 8°C) for 44.44% of the routes that were tracked, of which 30.55% had boxes assembled with medications and 13.88% had boxes containing vaccines. Therefore, for most of the routes (55.55%), the internal temperature of the boxes was outside the recommended range, i.e., below 2°C or above 8°C. It was concluded that the transport of thermolabile drugs and vaccines between the Regional and Municipal levels do not meet the technical specifications provided for in the Cold Network Manual. As the temperature within the boxes exceeded the recommended temperature range for more than half of the routes followed, it can be inferred that the processes related to the transport of these products are not being followed with the necessary rigor. Municipal managers should be aware of these needs including the modernization of measurement instruments and equipment and the investments in continued education for the team that operates the cold chain network.
Characterization of the homeless people affected by tuberculosis in Brazil, 2015 to 2021
Authors: Pavinati Gabriel , Lima Lucas Vinícius de , Magnabosco Gabriela Tavares
Published: June 2024

To describe the sociodemographic and clinical-epidemiological profile of homeless people affected by tuberculosis in Brazil, from 2015 to 2021. This is a descriptive, population-based epidemiological study, carried out from the tuberculosis notification records in the Brazilian homeless people, available in the Notifiable Diseases Information System. There was a predominance of male people, of mixed race/color, aged between 30 and 49 years, with (in) complete elementary education and who did not receive social benefits. Regarding the clinical-epidemiological aspects, the type of entry as a new case predominated, with the pulmonary form of the disease, directly observed treatment not performed, with loss of follow-up. The prevalence of alcohol and illicit drug use stands out, in addition to the large number of people who used tobacco. This scenario represents a great challenge, since the presence of tuberculosis prevails in this population, especially as a result of numerous risk factors and situations of vulnerability arising from being homeless. Thus, it is necessary to plan and improve actions that consider the specificities of the group, through inter- and intra-sectoral strategies, focusing on the articulation between public health services and social assistance.

To analyze the influence pattern of the defining variables that compose the Golden time developed by the Brazilian Mobile Emergency Care Service [Serviço de Atendimento Móvel de Urgência] (SAMU-192) in a municipality in Piauí. This is a documentary, descriptive study with a quantitative approach. A total of 337 medical records referring to the year 2018 were verified; data were collected at SAMU’s decentralized base. A sphericity test was performed to verify the possibility of generating a linear model through Mauchly’s test. Initially, an alpha below 0.46 was obtained, but the variables were negatively interfering in the model. After two more verifications, it was concluded that removing the variable did not influence the parsimony of the model. The generalized linear model showed statistical significance as to its fit (p-value<0.001) for the intercept and (p-value = 0.042) for the outcome variable – Golden time. It was possible to understand that SAMU is a viable action for first-aid efficiency and promptness, as well as for patient transport to appropriate reference services.

Published: June 2024

Zosteriform cutaneous metastasis (CM) is an infrequent form of skin metastasis and has a high chance of being misdiagnosed as herpes zoster. Here, we report a 55-year-old woman who had undergone modified radical mastectomy with adjuvant chemotherapy and radiotherapy for carcinoma left breast with painful lesions over the left side of her chest and upper back in a zosteriform distribution. She was misdiagnosed and treated for herpes zoster elsewhere. On grounds of clinical suspicion, we did a skin biopsy and confirmed the diagnosis of zosteriform CM from invasive ductal carcinoma of the breast. This case highlights the importance of considering CM in a patient with lesions of zosteriform distribution, as early diagnosis aids in preventing the delay in treatment of underlying malignancies.

Authors: Brar Gursimrat K. , Sodhi S. P. S.
Published: June 2024

ABSTRACT

The primary challenge associated with peripheral neurectomy is the occurrence of spontaneous nerve regeneration. This study focused on addressing this issue by employing a novel approach involving the use of sticky (steaky) bone to obliterate the foramina post-peripheral neurectomy. The study involved 56 patients diagnosed with trigeminal neuralgia, divided into two groups. In group I, the proximal nerve stump in the foramina was chemically cauterized after peripheral neurectomy, while in group II, sticky bone was used to obliterate the foramina. After a 2-year follow-up period, group II exhibited a significant improvement in the mean Visual Analogue Scale scores. Additionally, cone-beam computed tomography analysis revealed a noteworthy reduction in the size of the foramina in group II at 2 years post-operatively.

ABSTRACT

Background:

“Root canal treatment (RCT)” is essential in preserving natural dentition by eliminating infection within the root canal system. Irrigation solutions play a crucial role in achieving successful RCT outcomes by facilitating disinfection and debris removal.

Methods:

An in vitro experimental design was employed to evaluate the irrigation solutions. Antimicrobial efficacy was assessed using agar diffusion assays against Enterococcus faecalis and Candida albicans. Tissue dissolution ability was evaluated by measuring the weight loss of dentin specimens. Cytotoxicity was assessed using cell viability assays with human periodontal ligament fibroblasts.

Results:

NaOCl demonstrated the highest antimicrobial efficacy, while EDTA exhibited superior tissue dissolution ability. CHX and QMix displayed lower cytotoxicity compared to NaOCl and EDTA.

Conclusion:

The choice of irrigation solution in RCT should consider factors such as antimicrobial efficacy, tissue dissolution ability, and cytotoxicity. NaOCl remains effective but has high cytotoxicity, whereas CHX and QMix offer alternatives with lower cytotoxicity. EDTA is effective in tissue dissolution but should be used cautiously due to cytotoxic potential. Clinicians should weigh the benefits and limitations of each solution for optimal treatment outcomes.

Published: June 2024

ABSTRACT

Objectives:

The purpose of this study is to look at how often premalignant oral diseases are among patients who visit a tertiary care center, as well as how often these problems progress to become mouth malignancies.

Methods:

Between 2017 and 2022, 200 patients at a tertiary care facility who were identified with premalignant oral lesions had their medical records retrospectively examined. Information on lesion features, histological results, and demographics was gathered. Statistical analysis was used to determine the prevalence of premalignant oral lesions and the rate at which these lesions turned into oral malignancies, with a significance threshold of P < 0.05.

Findings:

The research population’s mean age was 55 years (SD ± 10), with a 65% male preponderance. The most prevalent premalignant lesions were leukoplakia (45%), erythroplakia (30%), and oral submucous fibrosis (25%). Remarkably, during follow-up, 40% of patients showed development of premalignant lesions into mouth malignancies. Based on statistical analysis, there were significant correlations (P < 0.05) between dysplastic alterations, age, tobacco use, and the development of oral malignancies from premalignant lesions.

Conclusion:

In conclusion, this study highlights the need of early diagnosis and focused therapies in tertiary care settings by offering important insights into the occurrence and evolution of premalignant oral lesions. The results provide important information that may be used to create screening programs and preventive measures that will lessen the incidence of oral cancer.

Published: June 2024

ABSTRACT

Background:

One potential long-term side effect of surgery in the oral and maxillofacial region is neurosensory impairment. Due to their physical proximity to the surgical location, the lingual nerve (LN) and inferior alveolar nerve (IAN), two sensory segments of the trigeminal nerve, are always susceptible to damage during third molar extraction.

Aim:

Assessment of the impact of different surgical techniques on nerve function and sensation after maxillofacial surgery.

Methods and Materials:

There was retrieval of information from medical records of study participants regarding the presence of symptoms like paresthesia, numbness, loss of sensation in lower lip, difficulty in movement of tongue, and all other findings observed after 7 days of surgical procedures. Clinically neurosensory examinations were utilized to assess nerve damage. Pinprick testing and the two-point discrimination test were used.

Results:

Seven male patients were found to have damage to LN while nine males suffered damage to trigeminal nerve. 12 female patients were found to have damage to LN while 16 females suffered damage to trigeminal nerve. In total 19 patients suffered damage to LN while 25 patients suffered damage to trigeminal nerve.

Conclusion:

The incidence of LN damage was 9.5%, and the incidence of trigeminal nerve damage was 12.5%.

Dirac points for twisted bilayer graphene with in-plane magnetic field
Authors: Becker Simon , Zworski Maciej
Published: June 2024

We study Dirac points of the chiral model of twisted bilayer graphene (TBG) with constant in-plane magnetic field. The striking feature of the chiral model is the presence of perfectly flat bands at
magic angles
of twisting. The Dirac points for zero magnetic field and non-magic angles of twisting are fixed at high symmetry points

K

and

K'

in the Brillouin zone, with

\Gamma

denoting the remaining high symmetry point. For a fixed small constant in-plane magnetic field, we show that as the angle of twisting varies between magic angles, the Dirac points move between

K

,

K'

points and the

\Gamma

point. In particular, near magic angles, the Dirac points are located near the

\Gamma

point. For special directions of the magnetic field, we show that the Dirac points move, as the twisting angle varies, along straight lines and bifurcate orthogonally at distinguished points. At the bifurcation points, the linear dispersion relation of the merging Dirac points disappears and exhibit a quadratic band crossing point (QBCP). The results are illustrated by links to animations suggesting interesting additional structure.
