Published: April 2023

La Cueva de la Orquídea es uno de los atractivos turísticos en Xalapa. Se ubica en un parque público con el mismo nombre en medio de la ciudad. Sin embargo, esta “cueva” en realidad es parte de un sistema de túneles de lava que se forman cuando lava poco viscosa (comúnmente basáltica) se enfría en el contacto con el subsuelo y la atmósfera, pero sigue fluyendo en su interior. La mayor parte del centro de Xalapa está construido por encima de estas lavas basálticas que subyacen el cono de escoria del Macuiltépetl. Se desconoce la ubicación de los túneles subterráneos de lava; solo en ocasiones se reportan hundimientos en la zona urbana, debido al colapso de algunas oquedades subterráneas, así como se descubren al excavar antes de iniciar una construcción. En este estudio, se emplean dos técnicas geofísicas no-invasivas dentro del área del Parque, así como en calles no pavimentadas en la cercanía del mismo. Los resultados del estudio de gravimetría y georadar no solamente hacen visibles las cámaras grandes (3 conectadas) previamente conocidas, sino revelan su continuidad hacia el Este, justo por debajo de las viviendas aledañas al parque. Se considera importante de seguir con los estudios para ubicar las oquedades más cercanos a la superficie y/o más voluminosas para identificar zonas potencialmente en peligro de colapsarse, adaptar planes de construcciones, entre otras medidas de mitigación.
 
Geophysical study of underground cavities near the Cueva de la Orquídea Park, Xalapa, Veracruz, Mexico
Abstract: The Cueva de la Orquida (Orchid cave) is one of the tourist attractions in Xalapa. It is located in a public park with the same name in the middle of the city. However, this "cave" is actually part of a system of lava tunnels that are formed when low-viscosity lava (commonly basaltic) cools on contact with the underground and the atmosphere, but continues to flow inside. Most of the center of Xalapa is built on top of these basaltic lavas that underlie the Macuiltépetl cinder cone. The location of the underground lava tunnels is unknown; only occasionally collapses are reported in the urban area, due to the collapse of some underground cavities, as well as being discovered when digging before starting construction. In this study, two non-invasive geophysical techniques are used within the Park area, as well as on unpaved streets in the vicinity of the Park. The results of the gravimetry and georadar study not only make the previously known large cameras (3 connected) visible, but also reveal their continuity to the East, just below the houses surrounding the park. It is considered important to continue with the studies to locate the cavities closer to the surface and/or more voluminous to identify areas potentially in danger of collapsing, adapt construction plans, among other mitigation measures.
KARL POPPER: REFLEXÕES SOBRE A LÓGICA DA PESQUISA CIENTÍFICA E AS SUAS CONTRIBUIÇÕES PARA O ENSINO DE CIÊNCIAS
Authors: Santos Diego Marlon
Published: April 2023

O presente estudo nos mostra uma revisão bibliográfica fundamentada na obra A Lógica da Pesquisa Científica de Karl Popper, destacando suas contribuições para o Ensino de Ciências. Portanto, foi possível perceber alguns aspectos principais na obra deste autor e a colocação de alguns problemas fundamentais, como: o problema da indução, a prova dedutiva de teorias, o problema da demarcação, a falseabilidade e o problema da base empírica, que consistem em instigações para encontrar critérios que possam reconhecer a importância das teorias empíricas científicas Neste contexto, foram analisados artigos científicos e livros relacionados na qual os autores abordam esta temática. Nessa perspectiva, constatamos que as teorias podem ser falseadas, onde a partir da dedução das previsões empíricas pelos pressupostos é possível realizar a comparação com o que é observado, podendo também testar por meio de experimentos. Diante disto, Karl Popper destaca um Ensino de Ciências, em que o professor antes de tudo precisa esquematizar os conhecimentos preexistentes dos alunos, como uma estratégia didática possível de ser utilizada em sala de aula. Assim, as contribuições das ideias de Karl Popper vão além do esclarecimento das teorias científicas, pois ajuda-nos a entender que o conhecimento científico não é duradouro, mas de fato temporário.
UNIVERSIDADE E ESCOLA EM PRISÕES: DIÁLOGOS E REFLEXÕES DA FORMAÇÃO EM SERVIÇO DE DOCENTES
Authors: Saraiva Emerson Sandro Silva , Mattos Maria Almerinda de Souza , Andreatta Elaine Pereira
Published: April 2023

O projeto de pesquisa e extensão de Formação em Serviço para docentes das unidades prisionais de Manaus compreende a discussão sobre a formação docente e a composição da cidadania por meio da ação reflexiva do docente na sociedade complexa. A formação em serviço e as atividades de extensão realizadas pela Universidade do Estado do Amazonas junto aos professores das unidades prisionais de Manaus fundamentaram-se na ideia de que cada sujeito presente na escola em prisões faz parte da apreciação das complexidades do real. Nesse sentido, partimos do princípio da dialógica e sua dimensão em reunir diferentes pessoas, verificar os vínculos e as relações complexas entre os sujeitos e as instituições para analisar a importância e parte dos resultados alcançados no processo de formação continuada realizado pela universidade junto aos professores da escola em prisões em Manaus- AM. Para tanto, foram realizados diálogos com Barbier (2004), Lucena, Saraiva e Almeida (2016), Norbert (2018), Borges (2019), Tardif (2014), entre outros, para compreender a conceitos relativos à formação, à escuta pedagógica, além da natureza da formação e da identidade docente. A metodologia dialógica baseou-se na reflexão, compreensão e ação em um ato que envolveu o cognitivo, o experiencial, o relacional, o investigativo e o diferente, possibilitando problematizar os ditos e os não ditos na formação docente, além de desnaturalizar as ideias impostas de uma educação determinada. Os resultados apontam que a formação em serviço é essencial para o fortalecimento da identidade docente, do saber plural dos professores, do saber heterogêneo que envolveu sujeitos, suas histórias, escutas, necessidades e conhecimentos. O trabalho aponta ainda que a Pesquisa e a Extensão provocaram movimentos dialógicos para que se examinasse a realidade por vários ângulos, interpretando suas relações, provocando reflexões, recursos de memória, registros, leituras de estudos científicos e recuperação de identidades para realizar releituras críticas e de caráter multiperspectival.

Published: April 2023

O presente texto expõe as contribuições da Modelagem Matemática em uma perspectiva da Educação Matemática, a partir das concepções de Burak (2004; 2010), relacionada a uma prática desenvolvida em uma turma de Sala de Apoio à Aprendizagem vinculada ao Colégio Estadual Antônio Xavier da Silveira- E. F.M.N localizado em Irati-PR. Essa prática foi fruto de uma parceria entre escola, universidade e pesquisadora do IFPR-Irati-PR. As práticas de Modelagem Matemática têm como etapa inicial a escolha de um tema de interesse dos estudantes, que nesse caso foram os esportes. Assim, partindo do relato detalhado da prática realizada em 2018, apresentamos uma investigação qualitativa baseada nas observações das professoras pesquisadoras, tendo por objetivo evidenciar as potencialidades da Modelagem Matemática para o aprendizado dos estudantes e para a formação inicial e continuada. Percebemos que a Modelagem Matemática se constitui em uma ferramenta que vem para inovar as aulas e contribuir para o aprendizado dos estudantes colocando-os como centro das atividades e o professor como mediador. Além disso, propicia reflexões importantes sobre as relações em sala de aula e os contextos dos conteúdos matemáticos, colocando os professores em movimento de formação permanente.
PRECEDENTE, IGUALDADE E SEGURANÇA JURÍDICA: O FUNDAMENTO DA PRESTAÇÃO JURISDICIONAL E DA EFETIVIDADE DA JUSTIÇA
Authors: Moreira Daniel Scaramella , Pagani Lucas Augusto Gaioski , Dias Bruno Smolarek
Published: April 2023

Os precedentes nasceram na tradição do Common Law, primeiramente como mecanismo de ilustração e, posteriormente, persuasão, para, ao final, culminarem como vinculação. Na busca por segurança jurídica, e em um ambiente de americanização e hibridização das tradições do Common Law e Civil Law, aterrissaram no Direito brasileiro cercado de dúvidas e expectativas. As expectativas residiam na possibilidade de correção de um velho problema cultural de patrimonialismo judicial, que influenciava, ainda que em pequena parte, decisões jurisdicionais, e estabelecia um ambiente de descumprimento de julgados anteriores. As dúvidas ainda encontram eco na forma de sua aplicação e na natureza jurídica de sua existência. Não obstante esses fatores pretende-se demonstrar, aqui, que os precedentes — ou um modelo de padrões decisórios por eles influenciado — é, ao mesmo tempo, instrumento que encontra justificação no princípio constitucional da igualdade e que pode auxiliar o Estado de Direito, pela via judicial, na concretização desse direito em seu aspecto material ou substancial.

Published: April 2023

SYNOPSIS:

Researchers often assign a label (such as a risk factor or predictor) to a characteristic that is statistically associated with an outcome (such as future injury). Labeling signifies that the characteristic has an established clinical value. More often than not, these labels are assigned prematurely and haphazardly. The rampant practice conflates research goals, the ultimate clinical value of the findings, and many risk factors/predictors that may not warrant the label. To address these issues and improve injury prevention research, we (1) outline the problem; (2) clarify the key differences between the research goals of description, causation, and prediction/prognosis (along with labeling conventions); (3) differentiate the clinical implications for each label; and (4) frame an appropriate scientific process to follow before applying a label.

Objetivo: Descrever os aprendizados e as experiências de um estágio em uma Clínica de Nefrologia, além do contato com o paciente portador de doença renal crônica. Relato de experiência: Embasado em uma visita em uma Clínica de Hemodiálise, realizada por 15 discentes do curso de Medicina e supervisionada por um médico Nefrologista durante estágio prático promovido pela Liga de Nefrologia, com o objetivo de sedimentar o conhecimento teórico acerca da especialidade clínica em questão e de compreender a dinâmica do procedimento de diálise. Considerações finais: O diagnóstico de doença renal crônica implica em alterações de hábitos não só do paciente, mas também da família, uma vez que o tratamento promove limitações físicas, funcionais, dietéticas e sociais. Essas limitações são ainda mais sérias em pacientes idosos, já que esses costumam possuir alguma morbidade associada. Por isso, uma abordagem mais humanizada, ética e empática por parte da equipe de saúde é fundamental para amenizar o impacto do tratamento; justificando, assim, o contato do estudante, desde a graduação, com as Clínicas de Nefrologia e hemodiálise.

Improvements in Resolution of 1H NMR of solids
Authors: Simões de Almeida Bruno , Emsley Lyndon
Published: April 2023

Magic angle spinning (MAS) in 1H NMR has allowed progress from featureless spectra in static samples to linewidths of a few hundreds of Hertz for powdered solids at the fastest spinning rates available today (100-150 kHz). While this is a remarkable improvement, this level of resolution is still limiting to the widespread use of 1H NMR for complex systems. This review will discuss two recent alternative strategies that have significantly improved 1H resolution, when combined with fast MAS. The first is based on anti-z-COSY, a 2D experiment originally used for J decoupling in liquids, which removes residual broadening due to splittings caused by imperfect coherent averaging of MAS. The second strategy is to obtain pure isotropic proton (PIP) spectra in solids, by parametrically mapping any residual broadening due to imperfect averaging into a second dimension of a multidimensional correlation spectrum.

Исследована сорбция поверхностно-активного вещества (ПАВ) олеата натрия в водном растворе на поверхности радела фаз вода-воздух. Измерена поверхностная активность ПАВ в зависимости от концентрации и температуры, рассчитана адсорбция олеат-иона, по значению которой определены параметры адсорбционных слоев и их зависимость от температуры. По экспериментальным зависимостям определены основные энергетические параметры сорбции: энергия Гиббса, энтальпия и энтропия образования поверхностного слоя олеата натрия. Процесс вывода олеат-ионов на поверхность раздела фаз является самопроизвольным, эндотермическим и характеризуется положительным значением энтропии, в силу отсутствия ограничения движения ионов на межфазной поверхности. Рассчитанные значения поверхностного слоя соизмеримы с линейными размерами олеат-ионов, что в области низких концентраций ПАВ характеризует поверхностную пленку как мономолекулярную.

The sorption of sodium oleate surfactant in aqueous solution on the surface of water-air phase division has been studied. Surfactant surface activity was measured as a function of concentration and temperature. Adsorption of oleate-ion was calculated; parameters of adsorption layers and their dependence on temperature were determined. The main energy parameters of sorption: Gibbs energy, enthalpy and entropy of formation of sodium oleate surface layer have been determined from experimental dependencies. The process of oleate ions withdrawal to the interface is spontaneous, endothermic and is characterized by the positive value of entropy due to the lack of restriction of ions movement on the interphase surface. The calculated values of the surface layer are commensurate with the linear size of the oleate ions, which in the area of low surfactant concentrations characterizes the surface film as monomolecular.

UNSTEADY AIR FLOW AS A FACTOR AFFECTING THE MECHANICAL PROPERTIES OF AVIATION MATERIALS
Authors: Иванов Д.А.
Published: April 2023

В данной статье рассматривается нестационарный воздушный поток в качестве значимого эксплуатационного фактора, оказывающего воздействие на структуру материалов элементов конструкции авиационной техники и, тем самым, на их механические и эксплуатационные свойства. В процессе эксплуатации воздушного судна продолжительное воздействие нестационарных дозвуковых газовых потоков может приводить к снижению конструктивной прочности элементов конструкции. Вместе с тем, использование обработки пульсирующим дозвуковым газовым потоком (газоимпульсной обработки) малой продолжительности в процессе технического обслуживания обеспечивает повышение механических свойств материалов авиационных деталей.

In In this article, the non-stationary air flow is considered as a significant operational factor affecting the structure of materials of structural elements of aviation equipment and, thereby, their mechanical and operational properties. During the operation of an aircraft, prolonged exposure to unsteady subsonic gas flows can lead to a decrease in the structural strength of structural elements. At the same time, the use of pulsating subsonic gas flow treatment (gas pulse treatment) of short duration during maintenance provides an increase in the mechanical properties of aircraft parts materials.
Questioning one-size-fits-all dialysis prescription: balancing dialysis prescription and residual kidney function
Authors: Fernandes João , Soares Rodrigues Anabela
Published: April 2023

Recent awareness of the viability and benefits of incremental hemodialysis is an opportunity to review clinical practices and improve the process of dialysis induction. Incremental dialysis is a standard approach in peritoneal dialysis prescription, with a focus on the quality parameter of nephroprotection. The same should apply in hemodialysis, with individualization of the prescribed extracorporeal technique: frequency, duration and intensity, in either home or center hemodialysis, are prescription variables to adjust according to the patient’s residual renal function, medical condition and psycho-social priorities. Considering that fluid balance and smooth ultrafiltration critically impact patient survival, incremental dialysis schedules need to be carefully tailored and grounded in routine residual kidney function measurement. This paper raises concerns about both the benefits of incremental dialysis and its putative detrimental effects, these being mainly dependent on the quality of the hemodialysis prescription and external economic constraints. As a comparator, incremental peritoneal dialysis is a scientifically based model to pursue, whichever the modality, based on updated concepts of patient-centered prescription and adequacy in dialytic renal replacement therapies.

Résumé
Les complications infectieuses représentent la deuxième cause de mortalité chez l’insuffisant rénal chronique notamment la tuberculose (Tb) qui reste plus fréquente chez les dialysés.Le but de notre travail est de déterminer la prévalence de la Tb chez nos patients en dialyse péritonéale (DP) et d’analyser le profil clinique, paraclinique et évolutif de cette infection.Il s’agit d’une étude transversale rétrospective, incluant les patients en DP avec diagnostic de la Tb. Nous avons analysé leur profil clinique et paraclinique, le diagnostic et la localisation de Tb, ainsi que l’évolution sous traitement.Nous avons retenu 12 cas de Tb parmi les 228 patients suivis en DP (5.26%) de 2006 à 2022, avec un sex-ratio H/F à 0.7 et un âge moyen de 52.7 ± 10 ans. Le délai médian entre le début de la DP et le diagnostic de la Tb était à 21 mois.Le diagnostic de Tb était retenu avec certitude dans 7 cas, en se basant sur des preuves bactériologiques et/ou histologiques. Le diagnostic était présomptif dans 5 cas sur un faisceau d’arguments cliniques et paracliniques. La localisation de Tb est pulmonaire dans 4 cas et extra-pulmonaire dans 8 cas dont 3 cas de péritonite tuberculeuse.Le traitement anti-bacillaire est débuté après un délai médian de 20 jours après le début des symptômes. Ce traitement s’est compliqué de 2 cas d’hépatite médicamenteuse et 1 cas de polynévrite.L’évolution est marquée par la guérison chez 11 patients. Concernant la péritonite tuberculeuse, le cathéter a été retiré chez un patient et maintenu dans les deux autres cas avec évolution favorable.En DP, le diagnostic de Tb est souvent difficile et les atteintes extra-pulmonaires sont plus fréquentes.

Allergic rhinitis (AR) is increasing at an alarming rate in Ukraine. The clinical picture of AR in modern conditions is changing towards more severe and mixed forms. Allergic rhinitis, especially moderate to-severe, has a negative impact on patient quality of life, productivity, direct, and indirect costs. Achieving adequate symptom control is essential for successful AR management, and relies mostly on pharmacotherapy. Most patients use multiple medications to control symptoms faster and better, but symptoms may persist. With the advent of new combination therapies, such as the intranasal formulation of azelastine hydrochloride and fluticasone propionate in a single device (MP-AzeFlu) like Dymista®, most AR symptoms can be treated effectively. MP-AzeFlu acts synergistically and blocks two important pathophysiological pathways involved in the early- and late-phase reactions of the disease, providing rapid relief from all AR-associated symptoms. A total of 13 experts from Ukraine, Germany, and India participated in the development of this consensus statement. The lead author drafted the questions pertaining to diagnosis, management, treatment adherence, and real-life evidence of AR in Ukraine, and was agreed with the co-authors and expert panel. This consensus is obtained through guiding statements and recommendations based on literature evidences (recent research outcomes, randomized, and comparative studies), clinical practices and personal experience of using MP-AzeFlu in AR by allergist/ immunologists/ otolaryngologists from Ukraine. This consensus statement aimed to assist practitioners in selecting the appropriate treatment strategies, facilitate optimum use of MP-AzeFlu and provide symptomatic relief for patients with AR in the in Ukraine

The aim of this study was to investigate the physical demands, physiological demands, and movement profiles of different positions across four quarters in professional men’s field hockey games. Eighteen professional male field hockey players participated in the study, and data were collected in eleven official matches. Players wore global positioning system units and heart rate monitors to collect physical, physiological, and movement profile data. Defenders had significantly higher absolute total distance covered, player load, acceleration and deceleration count, and forward-backward initial movement analysis (IMA) count, but lower high speed running distance, compared with midfielders and forwards (p<.05). However, when using relative metrics (normalised by playing time), defenders had the lowest physical and physiological outputs, and forwards were the highest (p<.05). Total distance covered per minute, high-speed running distance per minute, player load per minute, acceleration and deceleration count per minute, and repeated high-intensity efforts per minute were all significantly higher in quarter 1 than in other three quarters (p<.05). The percentages of linear running and non-linear dynamic movement duration decreased quarter by quarter. Modified training impulse per minute reached its peak in quarter 2 (p<.05). It was concluded that defenders had the highest volume in terms of the game demands due to their high playing minutes; however, they had the lowest relative volume compared with other two positions. Forwards had the highest linear running intensity, while midfielders were required to perform more multi-directional, non-linear movements. Quarter 1 was the most active quarter and players became fatigued in quarter 2. IMA counts were not sensitive to fatigue compared to movement profile and modified training impulse variables.

Although previous studies have indicated the importance of a core strength and muscular endurance training in preadolescents and adolescents, there is a lack of evidence regarding effects of a long-term core training in unstable conditions. The purpose of this study was to compare the effects of core training in stable versus unstable body positions on core and upper body strength and muscular endurance in non-trained children aged 11-14 years. Participants were randomly assigned to either stable (SC, N=569) or unstable (UC, N=633) core-exercise group and assessed at baseline, four, and eight months for sit-ups, dynamic trunk extension, static trunk extension, and push-ups. Repeated measures ANOVA, with time as a within factor, and exercise group, age, and gender as between factors, was employed for data analysis. Post-hoc comparisons showed greater absolute improvements after the eight-month training in UC compared to SC for all measures, age groups, and both genders (p≤.01), and greater relative improvements (differences in Cohen’s d between UC and SC ranged from 0.08 to 1.58), except for static trunk extension in 11- and 12-year-old participants. However, the differences between SC and UC in four-month effects were inconsistent. These results point out that core exercises in unstable compared to stable conditions have a greater capacity for long-term improvement of core and upper body strength and muscular endurance in non-trained preadolescents and adolescents.
21st Century Learners: Changing Conceptions of Knowledge, Learning and the Child
Authors: Hirschman Kate , Wood Bronwyn
Published: April 2023

The term ‘21st century learner’ emerged at the turn of the millennium and evoked a certain type of certain type of digitally‐agile and self‐driven learner. These ideas about 21st century learners have been widely and uncritically adopted in New Zealand policies and practices in recent years. This paper examines the origins and substance of this term against the backdrop of globalisation and Knowledge Economy discourses and emerging ideas of ‘digital natives’. It considers the implications of these ideas on conceptualisations of the child, the development of deep learning, the impact on relationships between adults/teachers and students and on social equity. It concludes by suggesting that the term 21st century learner needs onâ€going critique if we want critical, informed citizens in our democracy.

Objective: To explore the application effect of virtual simulation experiment combined with picture archiving and communication system (PACS) in medical imaging practical teaching. Methods: 97 students from the medical imaging class of 2022 were divided into two groups; the control group (n = 48) was taught by the traditional teaching method, whereas the research group was taught by virtual simulation experiment combined with PACS (n = 49). The teaching achievements and teaching effects of the two groups were compared to define the advantages of the two teaching modes. Results: Initially, there were no significant differences in the basic theory, image analysis, report writing, and differential diagnosis scores between the two groups of students (P > 0.05); however, after 16 weeks of teaching, the scores of the research group were better than those of the control group (P < 0.05); the pass rate of students in the study group (93.88%) was higher than that in the control group (81.25%); the scores of students in the research group in terms of clinical inquiry skills, X-ray/computed tomography/magnetic resonance imaging (X-ray/CT/MRI) operation skills, and doctor-patient communication skills were significantly higher than those in the control group (P < 0.05). Conclusion: In medical imaging practical teaching, the application of virtual simulation experiment combined with PACS can effectively address several problems in the traditional teaching mode, including the single teaching method, the single teaching content, and the lack of innovation, and, at the same time, improve students’ basic theoretical knowledge, X-ray/CT/MRI operation skills, consultation skills, and doctor-patient communication skills, thereby effectively improving the teaching quality and learning effect.

Background: Asthma is a common chronic noncommunicable disease which can impair the health-related quality-of-life (HRQOL) of patients. Aims: To investigate treatment-related experiences and HRQOL of asthma patients in Egypt during the COVID-19 pandemic. Methods: A multicentre cross-sectional study was conducted from 21 July to 17 December 2020 in 3 teaching hospitals in Egypt among a convenience sample of asthma patients. We used socioeconomic and clinical variables, perceived threat level of COVID-19, experiences before and during COVID-19, the Asthma Control Questionnaire (ACQ), and the mini Asthma Quality of Life Questionnaire (mini-AQLQ) to collect data. Results: Among the 200 respondents (66.0% male; mean age 40.2 years), 80.0% had uncontrolled asthma. The greatest impairment to HRQOL was due to limitation of activity. Females reported a higher level of perceived threat from COVID-19 (Chi squared = –2.33, P = 0.02). Before the pandemic, more patients visited the clinician when they had symptoms but did so more regularly during the pandemic. Over 75% could not differentiate between asthma and COVID-19 symptoms. Perceived uncontrolled asthma and poor compliance with treatment were significantly associated with impairment of HRQOL (P < 0.05) before COVID-19. Conclusion: The COVID-19 pandemic improved some asthma-related health behaviours, but limitations in HRQOL were still evident. Uncontrolled asthma is a key factor for HRQOL and should remain a focus for all patients.

A captive crested porcupine (Hystrix cristata) adult male was imaged due to reduced food intake, anorexia, fever, nasal discharge, changes in fecal quantity and size, and respiratory difficulties. Advanced imaging diagnostic techniques such as computed tomography and magnetic resonance imaging were performed to evaluate the animal. These techniques were very helpful to delineate the dental abscess, as well as the extension of the process to other locations such as the nasal cavity and the tympanic bulla. This is the first description of rhinosinusitis secondary to a dental abscess in a crested porcupine.
UPORABA RAČUNALNIŠKE TOMOGRAFIJE IN MAGNETNE RESONANCE ZA SLIKANJE RINOSINUZITISA, NASTALEGA ZARADI ZOBNEGA ABSCESA PRI AFRIŠKEM JEŽEVCU (Hystrix cristata)
Izvleček: Odraslega samca afriškega ježevca (Hystrix cristata) v ujetništvu smo slikali zaradi zmanjšanega vnosa hrane, anoreksije, nosnega izcedka, sprememb v količini in velikosti iztrebkov ter težav z dihanjem. Uporabili smo napredne tehnike slikovne diagnostike, kot sta računalniška tomografija in magnetna resonanca. Te tehnike so bile zelo koristne pri opredelitvi zobnega abscesa in razširitve procesa na druga mesta, kot sta nosna votlina in timpanični del temporalne kosti. To je prvi opis rinosinuzitisa, ki je posledica zobnega abscesa pri afriškem ježevcu.

VETERINARY ILLUSTRATION: SCIENCE AND ART TELLING A STORY TOGETHER
Authors: Kubale Valentina
Published: April 2023

At first glance, Science and Art seem to be very different, as Science is supposed to be objective and guided by data, while Art is subjective and strongly influenced by feelings and opinions. While the results of Science and Art are quite different, both processes have undeniable similarities. Both put ideas about the world into a form that allows the viewer to connect with the idea. Observing a cell, a snake, or human nature is what natural sciences and art depend on, albeit for different purposes. Veterinary and medical illustrations capture visual representations of the animal or human body or individual parts for documentation purposes, for teaching, or for veterinary/medical practice. They are closely related to historical, social, and technological developments that have influenced and have been influenced by the content of illustrations, the artists themselves, and the techniques used to produce, reproduce, and disseminate them from prehistoric and historical times to the present...
ILUSTRACIJA V VETERINI: ZNANOST IN UMETNOST SKUPAJ PRIPOVEDUJETA ZGODBO
Na prvi pogled se zdi, da sta si znanost in umetnost zelo raznoliki, saj naj bi bila Znanost objektivne narave ter podprta z pridobljenimi rezultati, medtem ko naj bi bila Umetnost bolj subjektivne narave ter močno pod vplivom občutkov in mnenj. Medtem, ko so rezultati, ki jih prinašata znanost in umetnost precej različni, sta hkrati po drugi strani obe zelo podobni, saj predstavita svoje ideje na način, da se opazovalec z njimi poveže. Znanost in umetnost temeljita na opazovanju bodisi celice, kače ali človeške narave, pa čeprav z različnim namenom. Veterinarske in medicinske ilustracije so bistvenega pomena za vizualno predstavljane zgradbe živalskega ter človeškega telesa oz. njegovih posameznih delov za namene dokumentiranja, poučevanja ali za namene veterinarske medicine / medicine v praksi. Tesno so povezane z zgodovinskim, družbenim in tehnološkim razvojem, na katerega je vplivala vsebina ilustracij, umetniki sami in tehnike, ki so jih uporabili za njihovo izdelavo, reprodukcijo in širjenje od prazgodovine do danes...
A flor de piel: esencialismos, sexilios, transfobias y experiencias lúdicas trans
Authors: Arriaga Ortiz Raúl , Escobedo Martínez Juan Francisco
Published: April 2023

El presente dossier de la revista LiminaR resulta particularmente interesante, ya que presenta por primera vez al lector, una serie de investigaciones en torno a las implicaciones corporalesde distintos sujetos que transgreden totalmente los discursos que dictan, de manera inequívoca y monolítica, los mandatos hegemónicos sobre el deber ser genérico. Los artículos aquí reunidos confluyen en la necesidad de recuperar distintas miradas cualitativas construidas desde la historia, la sociología y la etnografía para presentarnos las experiencias, prácticas y expresiones de las personas travestis, transgénero y/o transexuales, mismas que la heteronormatividad imperante considera liminales, marginales y abyectas, pero que sus practicantes ponen en marcha a pesar de las muchas adversidades a las que se enfrentan, aun a costa de diversas agresiones y la exclusión social.
