Abstract. The vertical distribution of ozone plays an important role in atmospheric chemistry, climate change, air pollution, and human health. Over the 21st century, spaceborne remote-sensing methods and instrumentation have evolved to better determine this distribution. We quantify the ability of ozone retrievals to characterize this distribution through a sequential combination of thermal infrared (TIR) and ultraviolet (UV) spectral radiances, harnessing co-located TIR measurements from the Cross-track Infrared Sounder (CrIS) on board the Suomi National Polar-orbiting Partnership (NPP) and UV measurements from the TROPOspheric Monitoring Instrument (TROPOMI), which is on the Sentinel 5-Precursor (S5P) satellite. Using the MUlti-SpEctra, MUlti-SpEcies, MUlti-SEnsors (MUSES) algorithm, the sequential combination of TIR and UV measurements, which follows retrievals from each instrument separately, moderately improves the ability of satellites to characterize global ozone profiles over the use of each instrument/band individually. The CrIS retrievals enhanced by TROPOMI radiances in the Huggins band (325–335 nm) show good agreement with independent datasets both in the troposphere and in the stratosphere in spite of calibration issues in the TROPOMI UV. Improved performance is characterized in the stratosphere from CrIS-TROPOMI, firstly through a modest increase in the degrees of freedom for signal (DFS; often between 0.1–0.2) and secondly through comparisons with the Microwave Limb Sounder (MLS), where a global multi-month-long comparison shows a mean difference ∼×10 lower than either CrIS or TROPOMI individually and R2 values 3 % higher. In the troposphere, CrIS-TROPOMI and CrIS show similar degrees of freedom for signal, with about 2 globally, but these are higher in the tropics partitioned equally between the lower and upper troposphere. CrIS-TROPOMI validation with ozonesondes shows improved performance over CrIS-only validation, with a difference in the tropospheric-column bias of between 30 % and 200 % depending on the season. Cross-comparisons with satellite instruments and reanalysis datasets show similar performances in terms of correlations and biases. These results demonstrate that CrIS and CrIS-TROPOMI retrievals have the potential to improve global satellite ozone retrievals, especially with future developments. If spectral accuracy is improved in future TROPOMI calibration, the degrees of freedom for signal in the stratosphere could double when using bands 1 and 2 of TROPOMI (270–330 nm), while tropospheric degrees of freedom for signal could increase by 25 %.

Abstract. The study of rock chemistry is a milestone in understanding fluid–rock interactions and fluid migration in subduction zones. When combined with thermodynamic models, it can provide direct insight into fluid composition, metasomatic reactions, and pressure–temperature (P–T) conditions, as well as their role in rock deformation. Here, a shear zone – located in the Mont Avic area of the Zermatt-Saas zone (Western Alps) – is analyzed. This shear zone consists of several blocks of different lithotypes, including a Ca-rich metasomatite block embedded in a serpentinite mylonitic matrix, and structurally underlies a coherent eclogitic mafic unit. This work aims to estimate the pressure–temperature conditions of the Ca-rich metasomatism and the amount of fluid involved. The brecciation exhibits mosaic breccia textures with clasts comprising ∼80 vol % of garnet, together with omphacite, epidote, titanite, rutile, and apatite hosted in an omphacite matrix. Quantitative chemical mapping of the garnet reveals primary garnet cores with embayment and lobate edges with a chemical composition similar to unaltered reference eclogite garnet. These primary garnet cores are overlain by Ca-rich metasomatic garnet rims with oscillatory chemical zoning. The oscillatory chemical zoning, together with the morphology of the primary garnet cores, suggests repeated influxes of external Ca-rich fluid that destabilized the primary garnet cores and promoted the growth of Ca-rich rims. Mass balance calculations between precursor metabasite and Ca-metasomatite indicate multiple fluid sources involving dehydrated serpentinite, calcic metasediments, and metabasites with time-integrated fluid fluxes calculated between 11.5×103 and 5.5×104 mfluid3 mrock-2, consistent with channelized fluid flow in an open system. Thermodynamic modeling of garnet from unbrecciated and non-metasomatized metabasites – from the Savoney eclogitic mafic unit – indicates peak metamorphic conditions of 2.5±0.1 GPa and 535±40 °C, consistent with regional estimates. Pressure–temperature conditions of metasomatism were constrained using P–X and T–X phase modeling (where X represents changes in bulk CaO and Na2O composition) between 2.6–2.2 GPa and 570–500 °C, showing that Ca-rich fluid percolation occurred close to the metamorphic peak (i.e., prograde to the peak or early exhumation path).
The Measurement Error Proxy System Model: MEPSM v0.2
Authors: Fischer Matt J. 
Published: September 2024

Abstract. Proxy system models (PSMs) are an essential component of paleoclimate data assimilation and for testing climate field reconstruction methods. Generally, current statistical PSMs consider the noise in the output (proxy) variable only and ignore the noise in the input (environmental) variables. This problem is exacerbated when there are several input variables. Here we develop a new PSM, the Measurement Error Proxy System Model (MEPSM), which includes noise in all variables, including noise auto- and cross-correlation. The MEPSM is calibrated using a quasi-Bayesian solution, which leverages Gaussian conjugacy to produce a fast solution. Another advantage of MEPSM is that the prior can be used to stabilize the solution between an informative prior (e.g., with a non-zero mean) and the maximum likelihood solution. MEPSM is illustrated by calibrating a proxy model for δ18Ocoral with multiple inputs (marine temperature and salinity), including noise in all variables. MEPSM is applicable to many different climate proxies and will improve our understanding of the effects of predictor noise on PSMs, data assimilation, and climate reconstruction.
openAMUNDSEN v1.0: an open-source snow-hydrological model for mountain regions
Authors: Strasser Ulrich , Warscher Michael , Rottler Erwin , Hanzer Florian 
Published: September 2024

Abstract. openAMUNDSEN (the open source version of the Alpine MUltiscale Numerical Distributed Simulation ENgine) is a fully distributed snow-hydrological model, designed primarily for calculating the seasonal evolution of snow cover and melt rates in mountain regions. It resolves the mass and energy balance of snow-covered surfaces and layers of the snowpack, thereby including the most important processes that are relevant in complex mountain topography. The potential model applications are very versatile; typically, it is applied in areas ranging from the point scale to the regional scale (i.e., up to some thousands of square kilometers) using a spatial resolution of 10–1000 m and a temporal resolution of 1–3 h or daily. Temporal horizons may vary between single events and climate change scenarios. The openAMUNDSEN model has already been used for many applications, which are referenced herein. It features a spatial interpolation of meteorological observations, several layers of snow with different density and liquid-water contents, wind-induced lateral redistributions, snow–canopy interactions, glacier ice responses to climate, and more. The model can be configured according to each specific application case. A basic consideration for its development was to include a variety of process descriptions of different complexity to set up individual model runs which best match a compromise between physical detail, transferability, simplicity, and computational performance for a certain region in the European Alps, typically a (preferably gauged) hydrological catchment. The Python model code and example data are available as an open-source project on GitHub (https://github.com/openamundsen/openamundsen, last access: 1 June 2024).
Regionalization in global hydrological models and its impact on runoff simulations: a case study using WaterGAP3 (v 1.0.0)
Authors: Kupzig Jenny , Kupzig Nina , Flörke Martina 
Published: September 2024

Abstract. Valid simulation results from global hydrological models (GHMs), such as WaterGAP3, are essential for detecting hotspots or studying patterns in climate change impacts. However, the lack of worldwide monitoring data makes it challenging to adapt GHM parameters to enable such valid simulations globally. Therefore, regionalization is necessary to estimate parameters in ungauged basins. This study presents the results of regionalization methods for the first time applied to the GHM WaterGAP3. It aims to provide insights into (1) selecting a suitable regionalization method for a GHM and (2) evaluating its impact on runoff simulation. In this study, four new regionalization methods have been identified as appropriate for WaterGAP3. These methods span the full spectrum of methodologies, i.e., regression-based methods, physical similarity, and spatial proximity, using traditional and machine-learning-based approaches. Moreover, the methods differ in the descriptors used to achieve optimal results, although all utilize climatic and physiographic descriptors. This demonstrates (1) that different methods use descriptor sets with varying efficiency and (2) that combining climatic and physiographic descriptors is optimal for regionalizing worldwide basins. Additionally, our research indicates that regionalization leads to spatially and temporally varying uncertainty in ungauged regions. For example, regionalization highly affects southern South America, leading to high uncertainties in the flood simulation of the Río Deseado. The local impact of regionalization propagates through the water system, also affecting global estimates, as evidenced by a spread of 1500 km3 yr−1 across an ensemble of five regionalization methods in simulated global runoff to the ocean. This discrepancy is even more pronounced when using a regionalization method deemed unsuitable for WaterGAP3, resulting in a spread of 4208 km3 yr−1. This significant increase highlights the importance of carefully choosing regionalization methods. Further research is needed to enhance the predictor selection and the understanding of the robustness of the methods on a global scale.
How a volcanic arc influences back-arc extension: insight from 2D numerical models
Authors: Zhang Duo , Davies J. Huw 
Published: September 2024

Abstract. Investigating plate tectonics through the lens of back-arc extension in subduction systems, this study introduces a “hot region” onto an overriding plate (OP) in 2D thermo-mechanical models, simulating the role of an arc. The models identified two extension locations on the OP: Extension in the Hot region (mode EH) and Extension at a Far-field location (mode EF), which is about 750 km from the trench. The study also found that extension can occur at the same far-field location without a hot region when the OP is young and thin or when the subducting plate (SP) is old with a high sinking velocity. Our models suggest that the EH mode is common, occurring in many cases like the Mariana Trough and Lau Basin, while the EF mode is rare, potentially occurring in locations like the Japan Sea. The primary driving mechanism in our models is poloidal flow beneath the OP, and the extension process involves competition between basal drag, which thins the OP, and thermal healing, which thickens it, as well as competition between thermal weakening in the hot region and that at the far-field location. Increased trench retreat rates, facilitated by increased hot-region temperature and width, have encouraged this flow and have consequently promoted back-arc extension.
La conférence de Berlin et sa résonance dans le roman postcolonial africain contemporain
Authors: MAMBI MAGNACK Jules Michelet 
Published: September 2024

La présente étude nous plonge au cœur de la problématique ancienne, mais toujours pertinente, du rapport entre le roman africain et l’histoire. Les textes que nous analysons convoquent un grand événement historique, la conférence de Berlin, dont les effets modélisent le fonctionnement de la société africaine et de ses institutions actuelles. Cet événement marquant de l’histoire de l’Afrique, ainsi que ses conséquences sociales et politiques (fractures et reconfigurations des territoires et des nations, conflits ethniques et politiques...), nourrissent les trames narratives de ces textes. Nous nous investissons à montrer comment l’écriture littéraire articule l’histoire sociale et institutionnelle du continent. L’on constate que ces textes se caractérisent par un envahissement du discours romanesque par le discours historique, à travers une profusion de faits historiques réels travaillés par le pouvoir créatif des auteurs. Il s’agit pour ces derniers de décentrer le logos de l’histoire centré exclusivement sur la perception occidentale, en proposant leur propre version. Une telle étude constitue une invitation à se défaire de la hantise du passé et à se projeter résolument dans le futur, en visant une meilleure appropriation de l’histoire pour mieux construire le futur à travers l’application de choix géopolitiques judicieux et la construction des nations africaines unies dans leurs diversités.
Ensino Formal e Homeschooling: Uma análise crítica à luz do direito à educação no Brasil
Authors: Rocha Zacharias Mariana , Wrubleski Simone Aparecida 
Published: September 2024

Neste artigo discute-se o homeschooling ou educação domiciliar, refletindo sobre o direito à educação no Brasil. A pesquisa teve por objetivo, debater esta modalidade, à luz da Constituição Federal e demais legislações. Como questão problematizadora discutimos se o direito à educação, enquanto princípio constitucional, seria violado, caso este tipo de ensino fosse regulamentado. Por fim, foram levantadas hipóteses a respeito das implicações deste tipo de educação para a interação e socialização de crianças e adolescentes. A metodologia utilizada caracteriza-se como levantamento bibliográfico e análise de documentos legais, como Constituição Federal, Lei de Diretrizes e Bases da Educação Nacional e Estatuto da Criança e do Adolescente. Como base teórica, foram utilizados, principalmente, os trabalhos de Cury (2002, 2014, 2023), Barbosa (2016) e Quadros (2021). A partir desta perspectiva teórica e documental, constatou-se que o movimento do homeschooling se baseia em direitos individuais que desconsideram o direito à educação previsto na Constituição, propagando perspectivas de privatização, além de não assegurar a socialização e a pluralidade de ideias, necessárias ao desenvolvimento dos estudantes enquanto cidadãos.

From the stars to your table - plants as complex conduits for iron nutrition
Authors: Long Terri 
Published: September 2024

Iron is a ubiquitous micronutrient that plays critical roles in central metabolic processes for all living organisms. The mechanisms by which plants extract iron from soil and maintain iron homeostasis are particularly intriguing. While it is relatively abundant, in most soils iron is insoluble and therefore of limited bioavailability, however excess iron accumulation in plants can lead to cellular damage. Thus, plants must extract sufficient quantities of iron from recalcitrant soil environments, while also ensuring that iron content does not exceed a specific range. Arabidopsis and other dicots have evolved mechanisms to sense iron deficiency in the shoot, which triggers roots to solubilize, reduce and uptake iron across multiple root cell types before transport to the shoot.Using a combination of molecular and confocal microscopy analysis, cell-type specific transcriptional profiling, and mathematical modeling we have uncovered several molecular mechanisms that control how plants recognize and respond to iron deficiency stress in a root cell-specific manner. Our findings provide new evidence for how distinct alternations in the root cortex control carbon metabolism in response to iron deprivation, and how iron deficiency causes specific developmental alterations in the root vasculature and epidermis. Together, these mechanisms operate to fine-tune root growth and physiology in the face of suboptimal growth conditions, while also providing new avenues for exploring inter- and intracellular nutrient stress response in plants.

Published: September 2024

BACKGROUND
Childhood obesity has emerged in the last decades as an important public health problem worldwide. Although relationships between obesity and flatfoot have been shown, no studies have investigated the influence of obesity on arthroereisis outcomes.
AIM
To evaluate correlations between childhood overweight/obesity and clinical and radiographic outcomes after subtalar arthroereisis with self-locking implants.
METHODS
This retrospective study included one hundred and sixty-nine pediatric patients (10-14 years old) who underwent subtalar arthroereisis (PEEK PitStop® device) for severe flexible flatfoot. Exclusion criteria were additional procedures, revision of previous corrective surgeries, rigid flatfoot with severe deformity, and neurological or post-traumatic flatfoot. Preoperative/postoperative European Foot and Ankle Society (EFAS) and visual analogue scale (VAS) scores were determined; radiographic assessment was conducted on weight-bearing foot X-rays: Kite angle, first metatarsal-talus angle, Meary angle, calcaneal pitch angle and lateral talo-calcaneal angle were analyzed.
RESULTS
EFAS and VAS scores improved post-operatively in the whole population. Only seven cases with complications were reported. Radiographic assessment revealed an improvement in all angles. Statistical analysis demonstrated that the impact of obesity was significant on arthroereisis outcomes: Relationships were reported between BMI and postoperative EFAS/VAS scores, postoperative calcaneal pitch angle, Kite angle, Meary angle and talo-first metatarsal angle.
CONCLUSION
Although arthroereisis represents a very effective and valid treatment for flatfoot both in normal weight and obese children, obesity significantly influences clinical and radiographic outcomes of arthroereisis, and obese children tend to perceive more pain and discomfort.

Published: September 2024

BACKGROUND
Platelet-rich plasma (PRP) injection is used as an alternative non-operative management for de Quervain’s tenosynovitis (DQT) to regenerate tendon healing.
AIM
To assess and conclude the research-based study systematically to analyse the efficacy of PRP on DQT.
METHODS
This systematic review used the Cochrane Handbook for Systematic Reviews and the guideline of preferred reporting items for systematic review and meta-analysis. A systematic literature search was applied to 11 databases. The authors assessed the study quality and risk of bias of each included study. Results of the meta-analysis were presented using mean difference (MD)/standardized mean difference (SMD) and 95% conﬁdence interval (CI).
RESULTS
The authors evaluated 275 studies found in the literature search; 12 studies met the criteria for this review, and then the study quality and risk of bias were assessed. Pooled analysis of data from two studies involving 194 subjects with DQT showed that, compared with conservative treatment, PRP injection was associated with a greater reduction in visual analog scale pain in one month and six months after treatment (MD: -0.67, P value < 0.00001; MD: -1.16, P value < 0.00001) and the increase of Mayo’s wrist score in one month and six months after treatment (SMD: 3.72, P value < 0.00001; SMD: 4.44, P value < 0.00001).
CONCLUSION
PRP can be used as an alternative non-operative treatment for DQT due to the tissue regenerative effect of PRP.
Modern And Classic Wound Dressing Comparison In Wound Healing
Authors: Rafika Nur Siregar  
Published: September 2024

Wound care has also developed rapidly after the dissemination of the concept of TIME (Tissue, Infection, Moisture, and Wound Edge) in modern dressing (MD). The aim of this study was to compare modern dressings (MDs) and classic dressings (CDs) in terms of patient comfort, cost effectiveness and wound healing. A prospective study design with total of 25 participants. The sampling technique used was consecutive sampling. Patient comfort was assessed through the frequency of wound care and pain scale using the Visual Analogue Scale (VAS). Cost-effectiveness was assessed using direct and indirect costs. Wound healing was assessed using the Bates-Jensen Wound Assessment Tool (BWAT) score. The data was analyzed using the independent t and Mann-Whitney tests. The application of MD has the same cost-effectiveness as CD with a more satisfactory outcome for the wounds in terms of comfort and healing.
