A imortalidade do ser amado segundo Gabriel Marcel
Authors: De Azevedo José André , Peretti Clélia
Published: August 2023

O objetivo deste artigo é abordar, a partir do pensamento do filósofo francês Gabriel Marcel (1883-1973), a temática da morte, mas não a morte enquanto “minha”, à minha morte; aborda-se aqui a morte do ser amado. Aquele e aquela que amei, que me amaram, para onde vão após a morte? Como a partida do ser amado afeta metafisicamente aquele que a morte devastou? Abordando a morte do ser amado não como um “problema” a ser resolvido, mas como um “mistério” a ser vivenciado, Marcel aponta a fidelidade como condição imprescindível para a compreensão sobre a imortalidade de quem amamos. A fidelidade, aqui, é vislumbrada não como uma simples promessa, mas como engajamento de meu ser num “tu”. Nesse sentido, somente o amor é capaz de desvelar o ser imortal que participa de nossa vida. Apenas uma relação fundada sobre o amor e a reciprocidade conduz à “comunhão do nós”; quanto mais um ser é amado como ser, menos sua morte é ressentida como perda dolorosa de uma “posse objetiva”.
Coincidência entre Essência e Aparência: Sobre a Possibilidade de uma Ontologia Fenomenológica.
Authors: Palmier de Almeida Lucas Gonçalves
Published: August 2023

Jean-Paul Sartre foi um dos grandes nomes da filosofia francesa contemporânea que, no início do século XX, recebeu a influência da fenomenologia vinda da Alemanha nas figuras de Husserl e Heidegger. Nesse sentido, a obra sartriana mais conhecida é O Ser e o Nada: ensaio de ontologia fenomenológica. O presente trabalho busca marcar o ponto nevrálgico que possibilitou Sartre, na sua recepção da fenomenologia na Introdução de O Ser e o Nada, construir uma ontologia fenomenológica e, com isso, evidenciar como é possível uma ontologia deste tipo. Para tanto, primeiramente, faremos uma recapitulação da trajetória sartriana a fim de compreender o que o levou às investigações ontológicas. Em seguida, evidenciaremos como a fenomenologia husserliana, recebida por Sartre, produziu uma coincidência entre aparência e essência, o que será fundamental para a ontologia proposta. Por fim, a partir do problema do ser da aparição, que surgirá a partir das análises anteriores, mostraremos como a ontologia, em Sartre, será compreendida enquanto uma descrição do fenômeno de ser, tal como ele se manifesta.

Alzheimer’s disease (AD) is a progressive and neurodegenerative illness which results in alterations in cognitive development. It is characterized by loss/dysfunction of cholinergic neurons, and formation of amyloid plaques, and formation of neurofibrillary tangles, among other changes, due to hyperphosphorylation of tau-protein. Exposure to pesticides in humans occurs frequently due to contact with contaminated food, water, or particles. Organochlorines, organophosphates, carbamates, pyrethroids and neonicotinoids are associated with the most diagnosed incidents of severe cognitive impairment. The aim of this study was to determine the effects of these pesticides on the phosphorylation of tau protein, and its cognitive implications in the development of AD. It was found that exposure to pesticides increased the phosphorylation of tau protein at sites Ser198, Ser199, Ser202, Thr205, Ser396 and Ser404. Contact with these chemicals altered the enzymatic activities of cyclin-dependent kinase 5 and glycogen synthase kinase 3 beta, and protein phosphatase-2A. Moreover, it altered the expression of the microtubule associated protein tau gene, and changed levels of intracellular calcium. These changes affected tau protein phosphorylation and neuroinflammation, and also increased oxidative stress. In addition, the exposed subjects had poor level of performance in tests that involved evaluation of novelty, as test on verbal, non-verbal, spatial memory, attention, and problem-solving skills.

Re-documenting the US Invasion of Panamá amid the Contact Zone in Diciembres
Authors: Woo Stephen
Published: August 2023

abstract: Using the film Diciembres (Decembers, Enrique Castro Ríos, 2018) as its case study, this article details the historical link between the Panama Canal—from its construction to ensuing struggles for its control—and the early development of cinema. The article moreover interrogates the zoning practices that inform the logics of both the canal and cinema in general. The argument puts film theory and decolonial thought into conversation with Diciembres , which narrativizes the 1989 US invasion of Panamá, as the formal operation of this film demonstrates yet transgresses the notion of a "contact zone" within de/colonial imaginaries.
Reciprocity between Nurses and a Remote Rural Community from 1912 to 2021
Authors: Whitehead Kay
Published: August 2023

Abstract: This historical study explores the relationships between nurses and a remote rural community, namely Marree in South Australia. Since 1912, Marree's nurses, mostly working singlehandedly, have provided general, midwifery, emergency, and public health services in a community marked by ongoing inequalities between white, Afghan, and Aboriginal people. A 'cottage hospital' was built with local funds in 1916, and the comprehensive health service became the focus of inkind support and community fundraising. The article highlights the reciprocity between the nurses and residents of Marree and surrounding pastoral stations, and demonstrates that Marree's nurses and health clinic continue to be integral to the contemporary community's identity.
Virus on the March?: Military Model and Metaphor in the COVID-19 Pandemic
Authors: Anderson Warwick
Published: August 2023

Abstract: What should a medical historian say when an army general calls, asking for advice on a vaccine rollout during a pandemic? For generations, we have heard warnings of the dangers of facile resort to war metaphors in dealing with epidemic disease. But what if public health originally derived from military models, from martial modes of defence against adversaries? What if militarisation is just business as usual? Increasingly, our response to modern crises, whether bushfires, floods, or pandemics, involves calling in the military. But the military metaphors and models that guide our interventions have varied over time and place. Some have worked better than others. Some have been less coercive than others. Medical historians thus can help counsel a sensitive general in search of the lessons of public health's pasts—even as they reflect critically on how such 'lessons' might themselves frame our thinking on the pandemic.
Making the Invisible Visible: For a Climate Future
Authors: Hsu Angel
Published: August 2023

Abstract: Climate change is rapidly transforming our world in ways both visible and invisible. Greenhouse gases—invisible to the human eye—cause climate change, with widespread impacts to which we now bear witness. Devastating floods and record-breaking heat waves are some more visible effects. There are others that remain mostly unseen. Making the invisible visible is at the core of this issue of Southern Cultures : using images and words from the contemporary South to show the ubiquity of climate change and how we all experience it. The latest climate science describes in stark detail a narrowing window for meaningful climate action. Despite the science, and policymakers' attempts to negotiate a solution, we haven't yet turned a corner on climate change. While we have the solutions to reduce emissions today, we lack the requisite inspiration and will.
The Inner Banks: A Drive Home
Authors: Bergman Megan Mayhew
Published: August 2023

Abstract: The author describes a journey to her home state of North Carolina from Vermont to find a more profound connection from which to draw for her environmental and fictional writing. Thinking of a place that she can call home, she drives through the state, specifically the Inner Banks region, while considering her personal experiences with the area and intimate understanding of its idiosyncrasies. She also contemplates the difficulty of portraying these elements and their complexities in a genuine way that is free of hyperbole. A particular focus is the area's environmental context and how it contributes to and is affected by climate change, which ultimately leads the author to a realization about her lack of true understanding of the Inner Banks, and the importance of learning about it in a more personal way.

Published: August 2023

To address problems such as the lack of accuracy in acquiring depth maps for dynamic fish 3D measurements by usual binocular vision or a time-of-flight (TOF) depth camera, a TOF-assisted binocular vision depth acquisition algorithm is used to obtain high-quality depth maps. The TOF depth energy function is designed to guide the binocular stereo matching process, which improves the correct matching rate of binocular matching in low-texture regions; the TOF and binocular stereo matching confidence weighting functions are designed to achieve the fusion of the two at pixel level to improve the matching quality of fish in the occluded overlapping regions. The experimental results show that the TOF-assisted binocular vision system improves the accuracy of fish size measurement compared to single binocular vision while reducing the measurement error when the fish body has a significant inclination along the depth axis.
Computational analysis of a scalable optically homogeneous free-space interferometer
Authors: Pung Aaron J.
Published: August 2023

This study describes a scalable optically homogeneous free-space interferometer. Computationally modeled as an unbroken block of fused silica, the interferometer’s six-sided design is simple and intuitive, exploiting total internal reflection and refraction to split and recombine a collimated input beam. During propagation, one portion of the split beam remains within the substrate to act as a reference beam. The second portion of the split beam is exposed to the surrounding environment, enabling real-world environment characterization in real time. Validation of the interferometer concept is performed using numerical and analytical techniques. Based on its scalability and robustness, the proposed interferometer design is primed for applications in atmospheric sensing, passive chemical detection, and spaceborne technologies.

Published: August 2023

The ray-mapping method has been widely used for designing freeform illumination lenses. However, in non-paraxial or off-axis situations, it remains challenging to obtain an integrable ray-mapping, often requiring a complex iterative correction process for the initial mapping. To address this challenge, we propose an extended ray-mapping method that incorporates differentiable ray-tracing into the design pipeline of the ray-mapping method. This enables accurate surface construction according to ray-mapping and efficient shape correction based on irradiance distribution. The proposed method involves two optimization stages. In the first stage, the freeform surface is preliminarily optimized to closely match the optimal transport mapping. The obtained freeform surface is then further optimized in the second stage to minimize the divergence between the target and simulated irradiance distributions. Additionally, the mean curvature of the freeform surface is also constrained in the second stage to facilitate the fabrication of the final freeform surface. Non-paraxial illumination lenses and off-axis illumination lenses have been designed using the proposed method within ten minutes, and simulations demonstrate that the approach is effective and robust.

Authors: Zhang Yang , Veilleux Sylvain , Dagenais Mario
Published: August 2023

Photonic integrated circuits based on ultralow loss silicon nitride waveguides have shown significant promise for realizing high-performance optical systems in a compact and scalable form factor. For the first time, we have developed a Fabry-Perot Bragg grating nanoresonator based on silicon nitride on silicon dioxide platform with an ultra-high intrinsic quality factor of 19.3 million. By combining the introduction of tapered grating between cavity and periodic Bragg grating, increasing the width of cavity to multi-mode region and optimized annealing strategy for Si3N4 film, the propagation loss is reduced to around 0.014 dB/cm. Fabry-Perot Bragg grating nanoresonator can be easily implemented in a simple straight waveguide occupying a minimal amount of space. Therefore, it is a key component to build a high performance photonic integrated circuit for many applications.
Broadband generation of multiple high-order OAM modes in ring-core fibers using multi-pitch chirped long-period fiber gratings
Authors: Chang Wenzhe , Shi Zekun , Wang Xin , Wang Pan , Wang Zhi , Liu Yan-Ge
Published: August 2023

A multi-order broadband mode converter in a ring-core fiber (RCF) using a multi-pitch chirped long-period fiber grating (LPFG), where multiple pitches were introduced in each chirp to further increase the bandwidth, is proposed and demonstrated. The grating parameters were optimized both theoretically and experimentally to achieve broadband mode generation of OAM ± 2 and OAM ± 3 modes by increasing the number of chirps and pitches. The mode conversion efficiency is higher than 90% with a broadband of 57 nm from 1456 nm to 1513 nm and 51 nm from 1573 nm to 1624 nm, corresponding to the second-order OAM mode and third-order OAM mode, respectively. Additionally, the insertion loss is less than 0.8 dB, and the purity is over 90%. The demonstrated mode converter has successfully achieved simultaneous generation of multi-order broadband OAM modes in a RCF for the first time, which has promising potential for application in OAM mode-division multiplexing systems.
Single-shot image restoration via a model-enhanced network with unpaired supervision in an optical sparse aperture system
Authors: Tang Ju , Zhang Jiawei , Ren Zhenbo , Di Jianglei , Wu Xiaoyan , Zhao Jianlin
Published: August 2023

We propose a model-enhanced network with unpaired single-shot data for solving the imaging blur problem of an optical sparse aperture (OSA) system. With only one degraded image captured from the system and one “arbitrarily” selected unpaired clear image, the cascaded neural network is iteratively trained for denoising and restoration. With the computational image degradation model enhancement, our method is able to improve contrast, restore blur, and suppress noise of degraded images in simulation and experiment. It can achieve better restoration performance with fewer priors than other algorithms. The easy selectivity of unpaired clear images and the non-strict requirement of a custom kernel make it suitable and applicable for single-shot image restoration of any OSA system.
Stable higher-charge vortex solitons in the cubic–quintic medium with a ring potential
Authors: Dong Liangwei , Fan Mingjing , Malomed Boris A.
Published: August 2023

We put forward a model for trapping stable optical vortex solitons (VSs) with high topological charges m. The cubic–quintic nonlinear medium with an imprinted ring-shaped modulation of the refractive index is shown to support two branches of VSs, which are controlled by the radius, width, and depth of the modulation profile. While the lower-branch VSs are unstable in their nearly whole existence domain, the upper branch is completely stable. Vortex solitons with m ≤  12 obey the anti-Vakhitov–Kolokolov stability criterion. The results suggest possibilities for the creation of stable narrow optical VSs with a low power, carrying higher vorticities.
Waveform Shaping in Photonic Time-Crystals
Authors: Hwang Ruey-Bing
Published: August 2023

This paper reports on the waveform shaped by a photonic time-crystal with its permittivity and permeability periodically varying in time. A Gaussian-modulated sinusoidal pulse is incident onto this photonic time-crystal to evaluate the backward- and forward-scattering waveforms. A temporal transmission-line network representation incorporating the inverse fast Fourier transform was developed to carry out the waveform computations rigorously. Interestingly, it is found that the momentum gap with a complex effective angular frequency plays an important role in shaping the incident waveform. Specifically, the coverage of momentum gaps in the spectrum of incident pulse determines the frequencies of oscillation modes being generated.

Tanzania is undergoing an epidemiological transition for malaria transmission with some areas of the country having <10% (hypoendemic) and other areas 10% - 50% malaria prevalence (mesoendemic). It is not known whether there is a difference in the quality of malaria case management based on endemicity in Tanzania mainland. We examined the influence of endemicity on the quality of malaria case management at health facilities. We conducted a cross-sectional analysis of 1713 health facilities in Tanzania mainland, using data collected by the National Malaria Control Program through an assessment tool to evaluate quality of malaria case management. The data was gathered from September 2017 to December 2018. Using standard quality factors, mean scores from facilities in the different endemicity regions were compared by a Student’s t-test. Simple and multiple linear regression analyses were performed to determine the association between facility performance (score) and endemicity (mesoendemic vs. hypoendemic). Facilities in mesoendemic regions scored higher than those in hypoendemic regions on the overall quality of services [difference in mean scores (d¯) = 2.52; (95% Confidence Interval (CI) 1.12, 3.91)], site readiness [d¯ = 2.97; (95% CI 1.30, 4.61)], availability of malaria reference materials [d¯ = 4.91; (95% CI 2.05, 7.76)], availability of Health Management Information System tools [d¯ = 5.86; (95% CI 3.80, 7.92)] and patient satisfaction [d¯ = 6.61; (95% CI 3.75, 9.48)]. Predictors associated with lower facility scores included; being located in a hypoendemic region [β: -2.49; (95% CI -3.83, -1.15)] and urban area [β: -3.84; (95% CI -5.60, -2.08)]. These findings highlight the differences in quality of malaria case management based on endemicity, but there is still a need to target improvement efforts in underperforming facilities, regardless of endemicity.
Association of body size distortion with low body mass index in female patients with nontuberculous mycobacterial lung disease
Authors: Takayama Yumi , Yumen Yukina , Kitajima Takamasa , Honda Noritsugu , Sakane Naoki , Fukui Motonari , Nagai Narumi
Published: August 2023

Background

We have previously reported that female patients with nontuberculous mycobacterial lung disease (NTM-LD) are thinner and eat less than healthy controls. Therefore, we hypothesized that their thinness is associated with body size misperception. The aim of this study was to clarify whether patients’ body size perception (BSP) is associated with body mass index (BMI) independent of potential confounders.

Methods

In this cross-sectional study, we assessed 81 outpatients for BSP using the Japanese version of Body Image Scale, body composition, dietary intake, and biochemical markers. As a control, we used BSP and self-reported anthropometric data from 111 healthy women collected via a web survey. First, BSP and BMI were compared between the patients and the controls. Second, patient data was compared between patients who overestimated their body size (OE, n = 31) and a control who did not (Non-OE, n = 50). Multiple regression analysis was performed to clarify the association between BSP (independent variable) and BMI (dependent variable), adjusting for potential confounders, such as age, disease duration, and nutritional factors.

Results

There was a negative correlation between body size distortion and BMI in both patients and controls (p < 0.001, both). In interpatient comparisons, the OE group had significantly lower BMI and body fat percentage (p < 0.001, both), normalized energy (p = 0.037), and protein (p = 0.013) intakes, and significantly greater weight loss from age 20 (p = 0.003) than the Non-OE group. Multiple regression analysis revealed that overestimation of body size was associated with lower BMI independent of confounders, such as longer disease history, longitudinal weight loss, and nutritional factors.

Conclusion

These findings suggest that body size distortion is an etiological factor for lower BMI in female patients with NTM-LD. Thus, it may be important to understand the patient’s body image when providing dietary advice.

The objective of this research was to evaluate the effects of 22 clonal rootstocks and own-rooted scion trees (without rootstock) on leaf nutrient contents (N, P, K, Ca, Mg, Mn, Fe, Zn, Cu and B) of the ‘Jade’ scion peach growing in a no-irrigated area with Peach Tree Short Life (PTSL) history, as well as their effects on nutrient agronomic interpretation. Macronutrient (N, P, K, Ca and Mg) and micronutrient contents (B, Cu, Fe, Mn and Zn) were determined in the first and second years after tree planting, in Pelotas-RS, Brazil. We conclude that leaf contents of P, K, Ca, Mg, B, Cu, Mn and Zn are influenced by the scion/rootstock combinations and own-rooted trees tested. Treatments changed agronomic interpretation classes of all macro and micronutrients. For macronutrients, ‘Flordaguard’, De Guia, Tardio-01 rootstocks and the own-rooted trees stood out, with leaf nutrient contents similar or even higher than trees grafted on ‘Capdeboscq’ and ‘Aldrighi’. For micronutrients, trees on GxN.9, ‘Ishtara’ and ‘Santa Rosa’ plum stood out. From a nutritional point of view, own-rooted ‘Jade’ peach trees did not present any limitations.
Ice in Motion: Panoramic Perspectives and Moving Pictures
Authors: Gapp Isabelle
Published: August 2023

The Arctic panorama has often been framed by conversations of the Victorian imperial imaginary and was originally conceived to showcase anglophone exploration, heroism, and scientific discovery. This paper explores the complementary and multifaceted visual representations of Arctic glacial ice, from the Victorian spectacle of the panorama to contemporary virtual reality technology. I look at how glaciers have been depicted, documented, and presented within panoramic media over the past two centuries. I explore how ice moves through both time and space, confronting climate histories within physical and spatiotemporal ideas of movement. Alongside the materiality of ice, I consider the modes of observation involved in creating and viewing these panoramic pictures. In making Arctic exploratory history tangible and visual, I do not seek to simply revive a sublime imaginary and document ice loss but look to the panorama as a method of engaging polar exploration and scientific discovery in the study of visual culture.

Published: August 2023

In this study, a closed-form analytical solution is derived to compute the stress formulations for a thick cylindrical pressure vessel made of functionally graded material (FGM) with varying parameters, which are mechanical and thermal boundary conditions. The assumed mechanical boundary condition is the time-dependent pressure acting on the internal surface of the cylinder, while the assumed thermal boundary condition is the transient temperature distribution over the cylinder thickness. The material properties are considered to be graded exponentially in the radial direction, except Poisson’s ratio which is assumed to be constant. The stress and displacement formulations are evaluated using Mathematica software for the uncoupled thermo-mechanical analysis. The results of radial, hoop, and axial stress are plotted at various times for two FGM cylinders, the SS304-Alumina FGM cylinder and the TZM-SIC FGM cylinder, to study the impact of using different materials for the same boundary conditions on the results. The results obtained in this study are beneficial as these contribute to the design and modeling of cylinders that are exposed to time-dependent internal pressure and transient temperature profiles.
Conceptualizing Russian Food in Emigration: Foodways in Culture Maintenance and Adaptation
Authors: Protassova Ekaterina , Yelenevskaya Maria
Published: August 2023

Food preparation and consumption is an essential part of culture. Leaving their homeland and finding themselves in a society with eating habits different from theirs, migrants face a dilemma of adapting their diets to those customary in their new place of residence or trying to maintain their food habits. Relying on the ethnographic method and applying thematic and critical discourse analyses, this article explores how Russian-speaking migrants discuss changes in their foodways and what role Russian food stores play in the life of immigrant communities. Material for analyses was drawn from fieldwork conducted in Finland, Germany, Israel, and Switzerland. It includes in-depth interviews, immigrants’ essays, and group discussions. We also studied culinary discussion groups on Facebook and documented linguistic landscape related to food consumption in the diaspora. Among the salient themes in the discourse dealing with eating habits abroad are food nostalgia, trying out familiar recipes with new products, evaluating traditional dishes of the host society, and re-evaluating Russian cuisine, searching for the right food in the new country and trying to showcase the best of one’s own cooking to other people. Immigrants’ discourse about food and the labels on the food products available in “Russian” stores outside Russia reveal frequent use of paroemias and quotations and allusions to Soviet and post-Soviet popular culture. Russian-speaking immigrants’ reflections about their old and new foodways reveal that they are an integral part of search for a new hybrid self-identity.

This paper presents a posteriori error estimate for the weak Galerkin (WG) finite element method used to solve
H
(curl)-elliptic problems. Firstly, we introduce a WG method for solving
H
(curl)-elliptic problems and a corresponding residual type error estimator without a stabilization term. Secondly, we establish the reliability of the error estimator by demonstrating that the stabilization term is controlled by the error estimator. We also evaluate the efficiency of the error estimator using standard bubble functions. Finally, we present some numerical results to show the performances of the error estimator in both uniform and adaptive meshes.
Merleau-Ponty and the Intellectualist Theory of Perception
Authors: Terzi Pietro
Published: August 2023

Merleau-Ponty’s relationship with his Sorbonne professor Léon Brunschvicg is usually disregarded or mentioned by scholars as a mere anecdote. Moreover, the rare discussions of the latter’s “critical idealism” usually take at face value Merleau-Ponty’s partial and biased account. In contrast, this paper argues that in order to understand the genesis of Merleau-Ponty’s thought, it is necessary to reassess Brunschvicg’s idealism and his views on the relationship between perception and scientific knowledge. Particular attention is drawn to a specific chapter of Brunschvicg’s masterworkL’Expérience humaine et la causalité physique, entitled “Théorie intellectualiste de la perception”. Therein is articulated the theory of perception that Merleau-Ponty never ceased to contest, and of which his entire oeuvre constitutes a reversal. However, far from highlighting only the elements of opposition, the author also points out the thematic continuity that survives the generational gap between the two authors.
Intergranular Corrosion in X39CrMo17-1 – A Review
Authors: Neidel A. , Gädicke T.
Published: August 2023

The aim of this contribution is to review cases of repeated snap ring failures in large gas turbine engine service due to intergranular attack, or intergranular corrosion, IGC, and to shed some light on metallurgical aspects of the wet corrosion resistance of the subject high-alloy martensitic stainless chromium steel X39CrMo17-1, DIN 1.4122. It is important to note that only snap rings, a.k.a. retaining rings for bores or Seeger rings, were affected by those failures, namely fractures resulting from intergranular attack (IGA,Kornzerfall). It was determined that the metallurgical root cause of failure was sensitization, resulting from secondary chromium carbide precipitation at grain boundaries (GB), and the ensuing chromium depletion in narrow bands adjacent to the GB, which rendered the matrix there sensitive to selective corrosion (the chromium content in these narrow seams, measuring only a few 10 nm in width, drops below the corrosion resistance threshold of ca. 10.5 %). Snap rings, as the name suggests, require a certain “snappiness” to serve their purpose. It is because of this requirement that all snap rings that experienced failures in the field were heat treated per DIN EN 10088-2, providing for a low tempering temperature of max. 250 °C, leading to a relatively high hardness of ca. 580 HV 10, providing said “snappiness”. It turned out that the microstructure resulting from this heat treatment (H/T) is sensitized, rendering the material sensitive to IGA. To the knowledge of the authors, no other components made of this martensitic stainless chromium steel are given this H/T, but rather a high-temperature tempering of 650 °C–750 °C per DIN EN 10088-3, producing a lower hardness in the order of ca. 300 HV 10 and largely a lack of “snappiness”, the latter being not required by those non-snap ring applications. Metallurgically, it became clear that high-temperature tempering per DIN EN 10088-3 eliminates sensitization by “backfill” diffusion of chromium from the non-depleted matrix into formerly depleted regions next to GB. It was therefore decided in the authors’ organization to eliminate X39CrMo17-1 per DIN EN 10088-2 as a possible material selection. The metallurgical investigations described in this contribution corroborate and support this decision.

Durant la pandémie, l’utilisation des technologies numériques est devenue incontournable pour rejoindre les élèves. Cette recherche-action porte sur les pratiques utilisées par les personnes enseignantes en éducation physique et à la santé du 2e cycle du secondaire pour engager les élèves dans l’adoption d’un mode de vie sain et actif. Des groupes de discussion ont été réalisés afin de dégager les facilitateurs et les défis rencontrés lors de ce changement de pratiques. Les résultats constituent une première phase de la recherche et permettent de préciser les étapes conduisant à la production d’un outil en soutien à l’enseignement-apprentissage.
NLR receptors in plant immunity: making sense of the alphabet soup
Authors: Contreras Mauricio P , Lüdke Daniel , Pai Hsuan , Toghani AmirAli , Kamoun Sophien
Published: August 2023

Plants coordinately use cell‐surface and intracellular immune receptors to perceive pathogens and mount an immune response. Intracellular events of pathogen recognition are largely mediated by immune receptors of the nucleotide binding and leucine rich‐repeat (NLR) classes. Upon pathogen perception, NLRs trigger a potent broad‐spectrum immune reaction, usually accompanied by a form of programmed cell death termed the hypersensitive response. Some plant NLRs act as multifunctional singleton receptors which combine pathogen detection and immune signaling. However, NLRs can also function in higher order pairs and networks of functionally specialized interconnected receptors. In this article, we cover the basic aspects of plant NLR biology with an emphasis on NLR networks. We highlight some of the recent advances in NLR structure, function, and activation and discuss emerging topics such as modulator NLRs, pathogen suppression of NLRs, and NLR bioengineering. Multi‐disciplinary approaches are required to disentangle how these NLR immune receptor pairs and networks function and evolve. Answering these questions holds the potential to deepen our understanding of the plant immune system and unlock a new era of disease resistance breeding.

Objective: to analyze the trends of mortality from HIV/AIDS in adolescents and young adults. Methods: ecological, time series investigation of deaths by HIV/AIDS in adolescents and young adults, from 2009-2019 in Brazil, in populated areas included in records from the System of Information on Mortality. We applied correcting factors to the mortality rates and carried out analysis using polynomial regression modeling. Results: we analyzed 6,344 deaths by HIV/AIDS in adolescents and young adults. We found high mortality rates in young adults when compared to adolescents. There was a growing trend in the north of the country, in the age group from 10 to 14. Mortality rates were higher among males in all regions, with a reduction in the mean rate for white persons and an increase for black/brown persons. Conclusion: there was an increasing trend, followed by a decrease in the last few years, with relevant differences between regions. The age group from 20 to 24 and males presented the highest mean rates of deaths from this disease. Contributions to practice: most of all, our findings give support to health planning, considering the specificities of the public and the regions with the most growing trends, thus helping improve public policies.

Background: The present study aims to evaluate the effect of local vitamin C application on inflammatory response and periodontal tissue destruction in rats with experimental periodontitis.

Methods: A total of 21 animals, 7 rats in each group, were used in the study: 1- Non-ligation (NL), 2-experimental periodontitis (EP), and 3- local vitamin C (VtC) groups. Experimental periodontitis was induced in EP and VtC group rats. After 11 days, the ligature was removed. 50 mL of saline solution and vitamin C were injected locally into the vestibule sulcus of the EP and VtC group rats, respectively. After the rats were sacrificed, blood and gingival tissue samples were taken. TNF-α levels were analyzed biochemically in serum and 8-OHdG and MMP-8 were analyzed immunohistochemically in gingival tissue. The mandibular specimens were histologically evaluated for bone destruction and attachment loss.

Results: The numeric density of 8-OHdG and MMP-8 immunopositive cells were found to be statistically significantly lower in the Vtc group than in the EP group. Vitamin C administration significantly reduced attachment loss and bone loss in the VtC group as compared to the EP group. However, there was no significant difference in serum TNF-α level in the VtC group compared to the EP group.

Conclusions: Local application of vitamin C may reduce inflammation-related bone destruction by supporting the inflammatory response with the antioxidant activity of vitamin C and contributing to the resolution of inflammation with its potential immunomodulatory effect. Vitamin C may be a therapeutic agent that can be used in the treatment of periodontitis.

Authors: ŞAHİN Veli , YILDIRIM Mücahid
Published: August 2023

Amaç: Bu çalışmada iskeletsel Sınıf III maloklüzyonların tedavisinde kullanılan yüz maskesi apareyinin sonlu elamanlar analizi (FEM) ile sirkümmaksiller bölgede meydana getirdiği değişimlerinin incelenmesi amaçlanmıştır. Farklı noktalarından ve doğrultulardan uygulanan kuvvetlerin çene ve yüz bölgesine etkileri değerlendirilmiştir.

Gereç ve Yöntemler: Bilgisayarlı tomografiyle (BT) alınan kesitlerin üç boyutlu olarak sonlu sayıda elemana ayrıştırılıp, tekrar birleştirilmesi ile sanal bir model elde edilmiştir. Tüm modellerde benzer tasarıma sahip diş-doku destekli ekspansiyon apareyi aracılığı ile 1000 gram şiddetinde protraksiyon kuvveti uygulanmıştır. Birinci modelde anterior bölgeden lateral ve kanin dişler arasından, ikinci modelde posterior bölgeden birinci molar diş hizasından olacak şekilde, üçüncü modelde ise hem anterior hemde posterior bölgeden kombine edilerek kuvvet uygulama noktaları modellere tanımlanmıştır. Ayrıca her bir modele oklüzal düzleme paralel, oklüzal düzlemden aşağı olacak şekilde 20°’lik ve 40°’lik açılandırmalarla protraksiyon kuvveti uygulanmıştır. Oluşan gerilme alanları sonlu elemanlar stres analiziyle incelenmiştir.

Bulgular: Çalışma modellerinde sirkummaksiller bölge incelendiğinde genel olarak pterygomaksiller sutur, frontonasal sutur, zigomatikofrontal sutur, premaksilla, maksillar alveoler çıkıntı ve zygomatik butress bölgelerinde yoğun stres alanları oluştuğu görülmüştür. Maksillada pterygomaksiller sutur ve çevresi, frontonasal sutur bölgesi genel olarak tüm modellerde en yüksek Von Mises değerine sahip stres bölgeleri olarak bulunmuştur.

Sonuç: Çalışmamızın sonuçlarına göre; dik yön büyümesine sahip olgularda maksiller anterior rotasyonun engellenmesi için, kuvvetin uygulama noktalarının mümkün olduğunca anteriorda konumlandırılması ve kuvvetin yönünün de oklüzal düzlemden 20° den daha aşağıda açılandırılması gerekmektedir.
