Seasonal Uptake and Partitioning of Macro- and Micronutrients in Yellow-Fleshed Kiwifruit (Actinidia chinensis var. chinensis)
Get PDFLittle information is available on the yellow-fleshed Zespri Zesy002 kiwifruit dynamic of mineral nutrient uptake and partitioning within organs. The aim of the present experiment was to find nutrient requirements and supply data for a specific nutrient management plan for Zesy002. The trial was conducted, for three years, in northern Italy, on a six-year-old kiwifruit orchard of the variety Zespri Zesy002. During the experiment organs were periodically sampled and analyzed for macro- and micronutrient concentration. A yearly nutrient uptake of 175 g N plant-1, 16 g P plant-1, 138 g K plant-1, 235 g Ca plant-1, 48 g Mg plant-1, 17 g S plant-1, 247 mg B plant-1, 673 mg Cu plant-1, 5.20 g Fe plant-1, 473 mg Mn plant-1, and 263 mg Zn plant-1 was calculated, confirming that kiwifruit is a high-nutrient-demanding species. The nutrients found in the tree organs were divided in two factions: removed (not returned into the soil) and recycled (returned into the soil during and at the end of the growing cycle). The two fractions were similar for N, P, K, S, and Mn. The fraction recycled of Ca, Mg, Cu, and Zn was higher than the fraction removed, and the reverse was observed for Fe. These data created the basis for the determination of the correct nutritional plans that take into consideration not only nutrient requirements but also the dynamics of uptake during the season
COVID-19 convalescent plasma for B-cell depleted patients: a systematic review and individual patient data meta-analysis
Get PDFCOVID-19 convalescent plasma (CCP) obtained from recently recovered people is safe and effective against SARS-CoV-2. Currently available CCP is a “hybrid” product with antibodies from individuals who had both infection and vaccination (vaccine-boosted CCP). B-cell depleted patients are at risk of not producing antibodies after either infection or vaccination, hence conceivably among those who would benefit the most from CCP. We thus conducted a systematic review and individual participant data meta-analysis to assess characteristics associated with 60-day survival in B-cell depleted patients transfused with CCP. The protocol was registered with PROSPERO (CRD42024516513) on March 1st, 2024. The last search was on April 2nd, 2024, and included all studies using CCP in B-cell depleted patients. Whenever not available, we requested individual participant data from corresponding authors of eligible studies. Risk of bias was assessed using Joanna Briggs Institute Critical Appraisal Tools. Data were analyzed using conditional logistic regression. The overall 60-day survival rate was 86.5% in our cohort of 570 patients (85 included studies). After controlling for age, sex, calendar year of infection and World Health Organization (WHO) disease severity, we found a significant association between 60-day survival and transfusion of vaccine-boosted CCP (OR = 9.49; 95% CI 2.01–44.82; p = 0.005). Overall survival in our cohort of B-cell depleted patients was consistent with prior meta-analysis of randomized controlled trials on survival of immunocompromised patient transfused with CCP (~84%). A novel finding from this analysis is that vaccine-boosted CCP is associated with a high survival benefit
Price competition, willingness to pay, and demand externalities under vertical differentiation
No full textThis paper explores how price competition is shaped by vertical differentiation, when demand externalities affecting the consumption of high-quality goods (such as a bandwagon effect) interact with income heterogeneity. To do so, we study how these externalities influence prices in a vertically differentiated duopoly, where the consumers’ willingness to pay for high-quality goods depends on market size, and the distribution of income is logconcave. We prove the existence and uniqueness of a Nash equilibrium in price strategies. Our findings reveal that stronger externalities favouring high-quality goods lower low-quality prices, but do not always raise high-quality prices: the impact on price competition depends on the income distribution, as the latter affects the co-movements of high-quality demand and its price elasticity
Probing Jupiter's Atmosphere Through Juno Radio Occultations: Methodology and Initial Observations
Get PDFThis paper presents an analysis of Juno's first radio occultation experiments. Relying on two-way radio links in the X- and Ka-bands, we processed data from NASA's Deep Space Network antennas through a ray-tracing inversion algorithm. By effectively isolating dispersive effects, we obtained measurements of the neutral atmosphere's characteristics. This enabled the derivation of pressure and temperature profiles from the recorded frequencies. These results complement prior data from Voyager occultations and CIRS observations, providing valuable contributions to our understanding of Jupiter's atmospheric dynamics
Coping, Resilience, and Post-Traumatic Growth in Shiga Izumi’s Mujō no kami ga maioriru (2017)
No full textThis contribution presents Shiga Izumi's work Mujō no kami ga maioriru (2017) as an example of a fictional account of the Tōhoku triple disaster. The study distinguishes coping skills, resilience, and posttraumatic growth, each exemplified by the protagonists' actions enacted by Shiga Izumi. This approach makes it possible to observe how the resilient qualities of the Japanese population are partly attributable to culture-specific factors, such as beliefs of a Buddhist philosophical matrix (mujō), and partly resulting from social support and mutual empathy that sees its healing power in social bonds (kizuna)
SO Emission in the Dynamically Perturbed Protoplanetary Disks around CQ Tau and MWC 758
No full textWe report the serendipitous detection of the SO JN = 65-54 (219.949 GHz) rotational transition in archival Atacama Large Millimeter/submillimeter Array observations of the spiral hosting protoplanetary disks around CQ Tau (with ≈4.9σ significance) and MWC 758 (with ≈3.4σ significance). In the former, the SO emission comes in the shape of a ring, arises from the edge of the continuum cavity, and is qualitatively consistent, at the currently available spectral resolution, with being in Keplerian rotation. In the latter, instead, while arising primarily from inside the continuum cavity, the SO emission also extends to the continuum ring(s), and its morphology and kinematics are less clear. We put these sources in the context of the other protoplanetary disks where SO detections have been previously reported in the literature and discuss the possible origins of SO in terms of (thermal) desorption or formation in the gas-phase. We argue that these processes might be fostered by dynamical perturbations caused by unseen embedded massive companions, shadows, or late-time infall, thus suggesting a possible link between perturbed dynamics and SO emission in (these) protoplanetary disks. If confirmed, our interpretation would imply that chemical evolution timescales could be significantly shorter in these systems than is commonly assumed, indicating that dynamical perturbations might influence the composition of newborn (proto)planets by altering the volatile makeup of their formation environment
TRACE-ing the Gaps: Mapping Interventions on Incomplete 3D Meshes
Get PDFThe 3D digital representations of physical objects are inevitably marked by gaps and imperfections arising from both technological
limitations and contextual acquisition constraints. These shortcomings often necessitate manual or semi-automatic interventions,
introducing elements of subjectivity into the modelling process. Despite the increasing use of 3D technologies across the Galleries,
Libraries, Archives, and Museums (GLAM) sector, a standardised methodology for classifying and documenting mesh incompleteness
is still lacking, undermining the transparency, reusability, and interoperability of such data. This paper addresses two core research
questions: (RQ1) Which acquisition conditions can be identified as the main contributing factors to the occurrence of holes in 3D
meshes? (RQ2) How can topological modifications resulting from the manual integration of holes in 3D cultural heritage models be
automatically tracked and visualised? To address these questions, we propose a classification framework grounded in five case studies
drawn from two digitisation campaigns conducted within the CHANGES project (Spoke 4). We further present a workflow for a posthoc, method-agnostic identification approach for the automatic tracing and interactive visualisation of topological edits, implemented
within a Web3D environment based on the ATON framework. Situated within a pipeline that adheres to FAIR principles, this
methodology aims to enhance the interpretability and scholarly value of digital reconstructions by embedding provenance-aware
metadata. Building on established approaches in critical architectural reconstruction, this work proposes a methodological extension
tailored to the nuanced management of holes in cultural heritage 3D models
Il caregiver come cure-giver: nuove soggettività di cura nella cronicità delle demenze
No full textPopulation ageing and the rise of dementia are shifting Italy’s long-term-care landscape from acute medicine to continuous assistance. Through 34 in-depth interviews (21 family caregiv-ers, 13 health-care professionals) conducted in Bologna, this qualitative study examines how relatives negotiate care pathways for persons with Alzheimer’s disease. Content analysis shows that caregivers perform body work, emotional labour, bureaucratic articulation and medication management, integrating domestic life with clinical requirements. These hybrid practices blur the canonical care/cure divide and generate a new subjectivity – the “cure-giver” – whose lay expertise enables continuity of treatment yet remains socially invisible and gen-dered. The article argues that acknowledging cure-givers as co-producers of health care is vital for equitable, integrated long-term-care policies and for reducing the hidden burdens currently shouldered by families
ATLAS Open Data to engage the public in Education and Research
No full textATLAS Open Data is an initiative aimed at making the data, simulations, and documentary resources of the experiment accessible to a wide audience, in accordance with the CERN Open Data policy. The project has seen the release of numerous datasets of proton-proton collisions at center-of-mass energies of 8 TeV and 13 TeV collected at the LHC during Run-1 and Run-2, allowing for the investigation of typical phenomena in high-energy physics. To facilitate their dissemination, the data are shared in accessible and commonly used formats. Additionally, they are accompanied by software and web interfaces designed for easy use, without the need for installation or coding by the user. The objective is twofold. On the one hand, the goal is to promote these activities in outreach and educational contexts, such as Summer Schools, Masterclasses, university projects, as well as various initiatives within the ATLAS Collaboration itself. On the other hand, high-energy physics research becomes accessible to an interdisciplinary audience, involving experts from other fields to benefit from their expertise, such as machine learning and computer science. This work provides an overview of the ATLAS Open Data resources, with concrete examples of how they can be used to promote scientific education and research in the field of particle physics
La Corte costituzionale 'allo specchio': Cappato II e il giudizio di costituzionalità sui propri precedenti. Quali coordinate minime?
Get PDFl presente contributo sfrutta l’occasione della sentenza n. 135/2024, quale leading case del sindacato sulle addizioni normative del Giudice delle leggi, per riflettere sul fenomeno di una “Corte costituzionale che giudica se stessa”. In particolare, il saggio sostiene che la Corte, attraverso le sue sentenze “manipolative”, possa produrre disposizioni pretorie aventi valore di legge. Pertanto, non solo tali disposizioni devono poter essere oggetto del sindacato di legittimità costituzionale ma, in questi casi, occorre che la Corte costituzionale ponga in essere, sul piano dell’interpretazione della ratio legis, un “tentativo di estraneazione” dal ruolo di autrice della disposizione, al fine di controbilanciare la carenza di alterità istituzionale che caratterizza queste situazioni.This paper takes Judgment No. 135/2024 as a leading case in the judicial review of laws created by the Constitutional Court, in order to reflect on the phenomenon of a “Constitutional Court judging itself.” I argue that, by means of its manipulative rulings, the Court may produce provisions having the force of law. Consequently, such provisions, must not only be subject to constitutional review, but the Court must also attempt an interpretive “detachment” from its role as author of the norm, in order to counterbalance the institutional lack of otherness that inherently marks this dynamic
