description: We have successfully synthesized a new BiS2-based superconductor NdOBiS2 with F-doping. This compound is composed of superconducting BiS2 layers and blocking NdO layers, which indicates that the BiS2 layer is the one of the common superconducting layers like the CuO2 layer of cuprates or Fe-As layer of Fe-based superconductors. We can obtain NdO1-xFxBiS2 with bulk superconductivity by a solid-state reaction under ambient pressure. Therefore, NdO1-xFxBiS2 should be the suitable material to elucidate the mechanism of superconductivity in the BiS2-layer.

Isotope study of the nonlinear pressure shifts of $^{85}$Rb and $^{87}$Rb hyperfine resonances in Ar, Kr, and Xe buffer gases

description: Measurements of the 0--0 hyperfine resonant frequencies of ground-state $^{85}$Rb atoms show a nonlinear dependence on the pressure of the buffer gases Ar, Kr, and Xe. The nonlinearities are similar to those previously observed with $^{87}$Rb and $^{133}$Cs and presumed to come from alkali-metal--noble-gas van der Waals molecules. However, the shape of the nonlinearity observed for Xe conflicts with previous theory, and the nonlinearities for Ar and Kr disagree with the expected isotopic scaling of previous $^{87}$Rb results. Improving the modeling alleviates most of these discrepancies by treating rotation quantum mechanically and considering additional spin interactions in the molecules. Including the dipolar-hyperfine interaction allows simultaneous fitting of the linear and nonlinear shifts of both $^{85}$Rb and $^{87}$Rb in either Ar, Kr, or Xe buffer gases with a minimal set of shared, isotope-independent parameters. To the limit of experimental accuracy, the shifts in He and N$_2$ were linear with pressure. The results are of practical interest to vapor-cell atomic clocks and related devices.

description: Pericytes at the blood–brain barrier (BBB) are located between the tight endothelial cell layer of the blood vessels and astrocytic endfeet. They contribute to central nervous system (CNS) homeostasis by regulating BBB development and maintenance. Loss of pericytes results in increased numbers of infiltrating immune cells in the CNS in experimental autoimmune encephalomyelitis (EAE), the mouse model for multiple sclerosis (MS). However, little is known about their competence to modulate immune cell activation or function in CNS autoimmunity. To evaluate the capacity of pericytes to directly interact with T cells in an antigen-specific fashion and potentially (re)shape their function, we depleted major histocompatibility complex (MHC) class II from pericytes in a cell type-specific fashion and performed T cell-pericyte cocultures and EAE experiments. We found that pericytes present antigen in vitro to induce T cell activation and proliferation. In an adoptive transfer EAE experiment, pericyte-specific MHC II KO resulted in locally enhanced T cell infiltration in the CNS; even though, overall disease course of mice was not affected. Thus, pericytes may serve as non-professional antigen-presenting cells affecting states of T cell activation, thereby locally shaping lesion formation in CNS inflammation but without modulating disease severity.

description: Higgs boson may serve as a portal to new physics beyond the standard model (BSM) which is implied by theoretical naturalness or experimental anomalies. In this note we briefly survey some Higgs-related BSM physics models, including the low energy SUSY (focusing on the minimal SUSY model), the little Higgs models, the two-Higgs-doublet models and the simplest singlet extensions of the Higgs sector. For each illustrated BSM model, we emphatically elucidate its phenomenological power in explaining current measurements of the muon g-2, the W-boson mass and the dark matter. For the singlet extensions like the xSM and 2HDM+S, we discuss the induced cosmic phase transition and the dark matter relic density as well as the vacuum stability. Finally, we give an outlook.

description: Using a particular form of the quantum K-essence scalar field, we show that in the quantum formalism, a fractional differential equation in the scalar field variable, for some epochs in the Friedmann-Lemaître-Robertson-Walker (FLRW) model (radiation and inflation-like epochs, for example), appears naturally. In the classical analysis, the kinetic energy of scalar fields can falsify the standard matter in the sense that we obtain the time behavior for the scale factor in all scenarios of our Universe by using the Hamiltonian formalism, where the results are analogous to those obtained by an algebraic procedure in the Einstein field equations with standard matter. In the case of the quantum Wheeler-DeWitt (WDW) equation for the scalar field $ϕ$, a fractional differential equation of order $β=\frac{2α}{2α-1}$ is obtained. This fractional equation belongs to different intervals, depending on the value of the barotropic parameter; that is to say, when $ ω_X \in [0,1]$, the order belongs to the interval $1\leq β\leq 2$, and when $ ω_X \in [-1,0)$, the order belongs to the interval $0< β\leq 1$. The corresponding quantum solutions are also given.

description: Following the reemergence of Russia as an aggressive power to the east and the invasion of Ukraine and annexation of Crimea, Sweden and Finland have decided to join the North Atlantic Treaty Organization (NATO). With the additions of Sweden and Finland, the security dynamic of the Baltic will change. The United States (US) has been the backbone of NATO since the Soviet Union, fell and as such, NATO has continued to be a major part of US foreign policy (USFP). If Finland and Sweden join NATO, then one of three scenarios will occur within USFP: (1) USFP in the Baltic becomes less involved because of the cohesive military presence created by NATO in the Baltic Sea becoming a sufficient deterrent to outside aggression; (2) USFP in the Baltic becomes more involved because NATO, while supplemented by Finnish and Swedish forces, is still not a strong enough deterrent to outside aggression; (3) the security dynamic remains the same, and the level of US involvement in the Baltic does not change as outside actors still pose a general threat to the border nations. This research outlines and evaluates these three scenarios through the use of alliance theory, current and past events, and comparative analysis. With the use of five variables based in alliance theory, this research ascertains that scenario (1) is the direction USFP will go as Finland and Sweden aid in crafting a cohesive deterring force allowing USFP resources to be focused elsewhere while still providing the Article 5 security guarantee.

description: Direct physical interaction with robots is becoming increasingly important in flexible production scenarios, but robots without protective fences also pose a greater risk to the operator. In order to keep the risk potential low, relatively simple measures are prescribed for operation, such as stopping the robot if there is physical contact or if a safety distance is violated. Although human injuries can be largely avoided in this way, all such solutions have in common that real cooperation between humans and robots is hardly possible and therefore the advantages of working with such systems cannot develop its full potential. In human-robot collaboration scenarios, more sophisticated solutions are required that make it possible to adapt the robot's behavior to the operator and/or the current situation. Most importantly, during free robot movement, physical contact must be allowed for meaningful interaction and not recognized as a collision. However, here lies a key challenge for future systems: detecting human contact by using robot proprioception and machine learning algorithms. This work uses the Deep Metric Learning (DML) approach to distinguish between non-contact robot movement, intentional contact aimed at physical human-robot interaction, and collision situations. The achieved results are promising and show show that DML achieves 98.6\% accuracy, which is 4\% higher than the existing standards (i.e. a deep learning network trained without DML). It also indicates a promising generalization capability for easy portability to other robots (target robots) by detecting contact (distinguishing between contactless and intentional or accidental contact) without having to retrain the model with target robot data.

We exemplify the efficiency of the analytical method on the orbits of test particles.

description: Cardiorespiratory fitness (CRF) and the subendocardial viability ratio (SEVR) decline with age and predict future cardiovascular disease (CVD) events in a sex-dependent manner. However, the relation between CRF and SEVR in apparently healthy males and females across the age span is largely unknown. We hypothesized higher CRF is associated with greater SEVR in older females, but not males. Two hundred and sixty-two (126M/136F, age range 20-84 yr) participants underwent measures of CRF (maximal O2 consumption [VO2max]) and SEVR (pulse wave analysis, PWA). A 2-way analysis of variance (ANOVA) was used to examine differences in baseline characteristics between younger (<45 y) and middle-aged and older (MA/O, ≥45 y) males and females. Bivariate correlations assessed the relation between CRF, SEVR, and age in males and females. Partial correlations adjusted for CVD risk factors and medications. MA/O females had the lowest CRF and SEVR compared to all other groups (p<0.05, both). SEVR was negatively correlated with age (r=-0.29) and positively correlated with CRF (r=0.53) in females (p<0.05, both) which persisted after controlling for CVD risk factors and medications (p<0.05, all). SEVR was correlated with CRF in males only after adjusting for CVD risk factors and medications (r=0.26, p<0.05). These findings collectively demonstrate higher CRF is associated with greater SEVR in males and females after adjusting for CVD risk factors and medications, therefore highlighting subtle sex-specific nuances which warrant further investigation.

A comprehensive model of morphologically realistic Cosmic Dust particles: an application to mimic the unusual Polarization properties of the interstellar Comet 2I/Borisov

description: The cosmic dust particles found in space are mainly porous aggregates of smaller grains. Theoretically, these aggregates are replicated using fractal geometry, assuming a cluster of spheres. Although, the light scattering response of cosmic dust aggregates has been thoroughly studied using clusters of spherical grains in the past few decades, yet, the effect of irregularities on the surface of each grain in an entire aggregate has mostly been neglected. We, for the first time, introduce a visually realistic cosmic dust model which incorporates a mixture of rough fractal aggregates (RFA) and agglomerated debris (Solids) to replicate the unusual polarization-phase curve observed in case of the interstellar comet 2I/Borisov at multiple wavelengths. The authenticity of the RFA structures has been verified by replicating light scattering results of circumstellar dust analogues from the Granada Amsterdam Light Scattering Database. We demonstrate that the light scattering response from the RFA structures has a very close resemblance with the experimental values. Finally, we model the observed polarization-phase curve of the interstellar comet 2I/Borisov using a mixture of RFA and solid particles. The best-fit data indicates presence of higher percentage of porous RFA structures 80% owing to the fact that the comet carries higher percentage of small and highly porous pristine cosmic dust particles. Further, the model indicates that the unusually steeper polarimetric slope and the high dust-to-gas ratio in relatively newer comets is mainly due to higher porous-to-compact ratio.

title: Adaptive proton radiation therapy via fast Monte Carlo dose calculation to correct for inter- and intra-fraction motion and geometry changes
Creators: name: Botas Sanmartin, Pablo
Publisher: name: Heidelberg University Library
Year: 2019

description: Intensity modulated proton therapy (IMPT) plans precisely balance thousands of proton beamlets, giving high dose to the tumor while trying to spare healthy tissues. However, plan quality is affected by factors including: 1) dose calculation inaccuracies, 2) underestimation of the biological effect of the dose in sensitive areas and geometrical changes like 3) patient movement or 4) changes in posture and anatomy. All these factors are addressed in the projects here presented.

Project 1, in collaboration, introduces an upgraded version of a Monte Carlo package for graphics processing units (GPU-MC) to provide fast and accurate dose calculations. This package is extended to serve as the unique dose calculation engine in the following projects.
Project 2, in collaboration, presents a prioritized optimization method to reduce the potential biological effect of the radiation in organs at risk near the tumor.

Project 3 compares computationally efficient strategies to take into account the patient respiratory motion by defining planning target volumes based on a 4DCT of the patient. Density overwrites considering water-equivalent-path-length to voxels across the 4DCT
targets works best.

Project 4 demonstrates an online algorithm that maintains IMPT plan quality through treatment, adapting it to the daily patient posture and anatomy using GPU-MC calculations.

description: Exponential, de Vaucouleurs, and Sérsic profiles are simple and successful models for fitting two-dimensional images of galaxies. One numerical issue encountered in this kind of fitting is the pixel rendering and convolution (or correlation) of the models with the telescope point-spread function (PSF); these operations are slow, and easy to get slightly wrong at small radii. Here we exploit the realization that these models can be approximated to arbitrary accuracy with a mixture (linear superposition) of two-dimensional Gaussians (MoGs). MoGs are fast to render and fast to affine-transform. Most importantly, if you have a MoG model for the pixel-convolved PSF, the PSF-convolved, affine-transformed galaxy models are themselves MoGs and therefore very fast to compute, integrate, and render precisely. We present worked examples that can be directly used in image fitting; we are using them ourselves. The MoG profiles we provide can be swapped in to replace the standard models in any image-fitting code; they sped up model fitting in our projects by an order of magnitude; they ought to make any code faster at essentially no cost in precision.

description: Sea ice is crucial in many natural processes and human activities. Understanding the dynamical couplings between the inception, growth and equilibrium of sea ice and the rich fluid mechanical processes occurring at its interface and interior is of relevance in many domains ranging from geophysics to marine engineering. Here we experimentally investigate the complete freezing process of water with dissolved salt in a standard natural convection system, i.e., the prototypical Rayleigh-Bénard cell. Due to the presence of a mushy phase, the studied system is considerably more complex than the freezing of freshwater in the same conditions (Wang et al. 2021c). We measure the ice thickness and porosity at the dynamical equilibrium state for different initial salinities of the solution and temperature gaps across the cell. These observables are non-trivially related to the controlling parameters of the system as they depend on the heat transport mode across the cell. We identify in the experiments 5 out of the 6 possible modes of heat transport. We highlight the occurrence of brine convection through the mushy ice and of penetrative convection in stably stratified liquid underlying the ice. A one-dimensional multi-layer heat flux model built on the known scaling relations of global heat transport in natural convection systems in liquids and porous media is proposed. It allows, given the measured porosity of the ice, to predict the corresponding ice thickness, in a unified framework.

description: The importance of the physical environment in the evolution of newly formed low-mass stars remains an open question. In particular, radiation from nearby more massive stars may affect both the physical and chemical structure of these kinds of young stars. Aims: To constrain the physical characteristics of a group of embedded low-mass protostars in Corona Australis in the vicinity of the young luminous Herbig Be star R CrA. Methods: Millimetre wavelength maps of molecular line and continuum emission towards the low-mass star forming region IRS7 near R CrA from the SMA and APEX are presented. The maps show the distribution of 18 lines from 7 species (H2CO, CH3OH, HC3N, c-C3H2, HCN, CN and SiO) on scales from 3" to 60" (400-8000 AU). Using a set of H2CO lines, we estimate the temperatures and column densities in the region using LTE and non-LTE methods. The results are compared with 1-D radiative transfer modelling of the protostellar cores. These models constrain which properties of the central source, envelope, and environment can give rise to the observed line and continuum emission. Results: Most of the H2CO emission from the regions emerges from two elongated narrow ridges dominating the emission picked up in both interferometric and single-dish measurements. The temperatures inferred from the H2CO lines are no less than ~30 K and more likely 50-60 K, and the line emission peaks are offset by ~2500 AU from the location of the embedded protostars. The temperatures can not be explained by the heating from the young stellar objects themselves. Irradiation by the nearby Herbig Be star R CrA could, however, explain the high temperatures. The elevated temperatures can in turn impact the physical and chemical characteristics of protostars and lead to enhanced abundances of typical tracers of photon dominated regions seen in single-dish line surveys of embedded protostars in the region.

description: This seminar targets both non-technical and technical researchers. ODAKTR is a bottom-up national initiative that aims to leverage METU and ODTÜ-GÜNAM’s participation in a cluster of 7 accepted, on-going, or completed Concentrated Solar Thermal (CST) EU projects to accelerate Turkey’s Clean Energy Transition (CET). A conceptual overview of CST technologies and applications is presented. The strategic role CST plays in Europe’s CET and Green Deal that is motivating Europe’s large investments in CST Research and Innovation (R&I), and the potential for CST to contribute to Turkey’s CET and Green Deal Action Plan are discussed. All of METU and ODTÜ-GÜNAM’s EU CST projects are strongly aligned with EUSOLARIS, which is one of 41 European Research Infrastructure Consortium (ERICs) Landmarks on the European Strategy Forum on Research Infrastructures (ESFRI) 2021 Roadmap. The potential to use ERIC’s as cost-efficient pathways to Turkish scientific excellence and to a secure, sustainable, and prosperous Turkey are defined. The current state of and future prospects for Turkey’s affiliation with EU-SOLARIS and other strategic ERICs are discussed.

description: The discovery of a SM-like Higgs boson near 125 GeV and the flavor texture of the Standard Model motivate the investigation of supersymmetric quiver-like BSM extensions. We study the properties of such a minimal class of models which deals naturally with the SM parameters. Considering experimental bounds as well as constraints from flavor physics and Electro-Weak Precision Data, we find the following. In a self-contained minimal model - including the full dynamics of the Higgs sector - top squarks below a TeV are in tension with b->sγ constraints. Relaxing the assumption concerning the mass generation of the heavy Higgses, we find that a stop not far from half a TeV is allowed. The models have some unique properties, e.g. an enhancement of the h-> b\bar{b},τ\bar{τ} decays relative to the h->γγ one, a gluino about 3 times heavier than the stop, an inverted hierarchy of about 3-20 between the squarks of the first two generations and the stop, relatively light Higgsino neutralino or stau NLSP, as well as heavy Higgses and a W' which may be within reach of the LHC.

description: Ion orbit loss has been used to model the formation of a strong negative radial electric field $E_r$ in the tokamak edge, as well as edge momentum transport and toroidal rotation. To quantitatively measure ion orbit loss, an orbit-flux formulation has been developed and numerically applied to the gyrokinetic particle-in-cell code XGC. We study collisional ion orbit loss in an axisymmetric DIII-D L-mode plasma using gyrokinetic ions and drift-kinetic electrons. Numerical simulations, where the plasma density and temperature profiles are maintained through neutral ionization and heating, show the formation of a quasisteady negative $E_r$ in the edge. We have measured a radially outgoing ion gyrocenter flux due to collisional scattering of ions into the loss orbits, which is balanced by the radially incoming ion gyrocenter flux from confined orbits on the collisional time scale. This suggests that collisional ion orbit loss can shift $E_r$ in the negative direction compared to that in plasmas without orbit loss. It is also found that collisional ion orbit loss can contribute to a radially outgoing (counter-current) toroidal-angular-momentum flux, which is not balanced by the toroidal-angular-momentum flux carried by ions on the confined orbits. Therefore, the edge toroidal rotation shifts in the co-current direction on the collisional time scale.

Li nas redes sociais que o Ministério Público teria solicitado judicialmente o "fim da declaração de óbito" para bebês abortados.
Notem. Se se trata de óbito qual seria o documento? Um atestado de eliminação? Quem sabe uma "elegia à supressão da vida"? Estranho? Uma "borracha dos acontecimentos"?
Não, não é estranho, e eu tentarei demonstrar.

description: We report the low-temperature electronic and magnetic properties of the alkali metal-organic solvent intercalated iron selenide superconductor Lix(C5H5N)yFe2-zSe using muon-spin-spectroscopy measurements. The zero-field \muSR results indicate that nearly half of the sample is magnetically ordered and there is a spatial phase separation between the superconducting and the magnetic fraction. The transverse-field \muSR results show that the temperature dependence of the penetration depth λ(T) in the mixed state of Lix(C5H5N)yFe2-zSe can be explained using a two-gap s+s-wave model with gap values of 6.82(92) and 0.93(7) meV. This implies that the symmetry of the superconducting gap in this system remains unaltered to the parent compound FeSe even after the intercalation with the molecular spacer layer. We obtain λ(0) = 485(21) nm at T = 0 K.

description: In the early stage of ultrarelativistic heavy-ion collisions chiral symmetry is restored temporarily. During this so-called chiral phase transition, the quark masses change from their constituent to their bare values. This mass shift leads to the spontaneous non-perturbative creation of quark-antiquark pairs, which effectively contributes to the formation of the quark-gluon plasma. We investigate the photon production induced by this creation process. We provide an approach that eliminates possible unphysical contributions from the vacuum polarization and renders the resulting photon spectra integrable inthe ultraviolet domain. The off-equilibrium photon numbers are of quadratic order in the perturbative coupling constants while a thermal production is only of quartic order. Quantitatively, we find, however, that for the most physical mass-shift scenarios and for photon momenta larger than 1 GeV the off-equilibrium processes contribute less photons than the thermal processes.

This allows us to probe the stability of the Bose-metal phase proposed in Varney et al (2011 Phys. Rev. Lett. 107 077201), against various changes in the originally studied Hamiltonian.

Evaluating the ability of desert locusts (Schistocerca gregaria) to grow when feeding on tomato leaves (Solanum lycopersicum) versus wheatgrass (Triticum aestivum)

description: The desert locust (Schistocerca gregaria) is a notorious swarm-forming agricultural pest widely collected for its use as food and feed. Its ability to grow on tomato leaf waste as a sole nutritional source was investigated given its ability to consume a wide range of plants. The growth and nutrient composition of desert locusts and their generated frass were compared in nymphs reared on tomato leaves versus wheatgrass. The desert locusts demonstrated higher growth on wheatgrass diet, but they also thrived on tomato leaves without observed mortalities. An average production of 14.38 g desert locust biomass consumed 375.8 g of fresh tomato leaves. Desert locusts fed with tomato leaves had higher crude protein content (61% compared to 58% in wheatgrass-fed desert locusts) and lower fat content (8% compared to 14% in wheatgrass-fed desert locusts). The diet also influenced the levels of Ca, Cu, Mn, S, and Zn in the desert locust biomass. Furthermore, the analysis of the generated frass revealed significant differences in the levels of B, Ca, Cu, K, Mg, Mo, Na, P, S, Zn, and N, depending on the plant material provided. The findings suggest that the desert locust can be reared efficiently on tomato leaves, transforming this waste stream into a protein-rich insect biomass and frass.

description: We consider p-branes with one or more circular directions fibered over the transverse space. The fibration, in conjunction with the transverse space having a blown-up cycle, enables these p-brane solutions to be completely regular. Some such circularly-wrapped D3-brane solutions describe flows from SU(N)^3 N=2 theory, F_0 theory, as well as an infinite family of superconformal quiver gauge theories, down to three-dimensional field theories. We discuss the operators that are turned on away from the UV fixed points. Similarly, there are wrapped M2-brane solutions which describe smooth flows from known three-dimensional supersymmetric Chern-Simons matter theories, such as ABJM theory. We also consider p-brane solutions on gravitational instantons, and discuss various ways in which U-duality can be applied to yield other non-singular solutions.

description: Flax fibres are valuable reinforcements for tomorrow's composites. However, defects called kink-bands, which mainly appear on fibres during the extraction and transformation phases, might affect their mechanical properties. Defects induced pores, within the kink-band are investigated in this work. They were morphologically explored using synchrotron phase-contrast X-ray microtomography, a technique that displays a sharp 3D representation of the pores. The study highlights the link between kink-bands and secondary cell wall ultrastructure. Pores are organised concentrically around the lumen, and their low thickness suggest that they are located at the interface between cellulose layers within S2 (G) layer. Moreover, the pores inclination with reference to the lumen axis follows the typical microfibrillar angle changes observed in the literature in the kink-band region. The volumes of the pores were measured, and a local increase in porosity was revealed in zones where defects are most severe along the fibre.

description: Let G be a finite group of Lie type, defined over a field k of characteristic p > 0. We find explicit bounds for the dimension of the first cohomology group for G with coefficients in a simple kG-module. We proceed by bounding the number of composition factors of Weyl modules for simple algebraic groups independently of p and using this to deduce bounds for the 1-cohomology of simple algebraic groups. Finally, we use this to obtain estimations for the growth rate of the maximum dimension {γ_l} of these 1-cohomology groups over all groups of Lie type of rank l. We find that log γ_l is O(l^3 log l) (or if the Lusztig conjecture holds, O(l^2 log l)).

description: Our knowledge of binding energies of neutron-rich nuclei has experienced a major revision during the last five years due to the introduction of Penning-trap based mass measurements. New mass values for nearly 300 nuclides produced in fission with uncertainties of 10 keV or less have become available. The data produced at three Penning trap facilities at Jyvaskyla, CERN-ISOLDE and Argonne cover all isotopic chains from Ni to Pr, except iodine. In this talk some of this data is reviewed and applied using the mass differentials such as two-neutron binding energy and odd-even staggering to probe their sensitivity on changes in nuclear structure and on the strength of the N=82 shell gap and associated pairing effects.

description: Zweck – Dieser Vortrag untersucht die sozialen Auswirkungen von Flugzeugen oder Flugzeugprojekten mit einem Lebenszyklusansatz am Beispiel des Programms Airbus A380.

Methodik – Soziale Auswirkungen werden analysiert, indem eine Social Life Cycle Assessment (S-LCA) basierend auf den "Guidelines for Social Life Cycle Assessment for Products" des Umweltprogramms der Vereinten Nationen (UNEP) und der Society of Environmental Toxicology and Chemistry (SETAC) durchgeführt wird. Stakeholder und Unterkategorien werden ausgewählt und Daten werden mit qualitativen Interviews und Webrecherchen gesammelt. Eine Folgenabschätzung wird mit der Subcategory Assessment Method (SAM) durchgeführt. Die Ergebnisse werden interpretiert und verallgemeinert.

Ergebnisse – Während seiner Lebensdauer hat ein Flugzeug oder Flugzeugprogramm Auswirkungen auf verschiedene Interessensgruppen. Die Lebenszyklusphase "Rohstoffgewinnung" könnte zu Menschenrechtsverletzungen führen, aber auch lokale Gemeinschaften in der Nähe der wichtigsten Produktionsstätten sind mit sozialen Auswirkungen konfrontiert, sowohl positiv als auch negativ. Die wirtschaftliche Bedeutung des Luftfahrtsektors beeinflusst die Gesellschaft, politische Entscheidungsträger, lokale Gemeinschaften und Arbeitnehmer. All dies zeigte sich auch im A380-Programm.

Grenzen der Anwendbarkeit – Die Datenverfügbarkeit schränkte die Untersuchung teilweise ein. Das Projekt deckt nicht alle Lebenszyklusphasen und Interessensgruppen ab. Stattdessen liegt der Fokus auf ausgewählten Phasen und Gruppen.

Bedeutung in der Praxis – Die Studie kann Entscheidungsträgern in der Luftfahrt helfen, ein Produkt bereitzustellen, das das Wohlergehen seiner Interessensgruppen verbessert.

Soziale Bedeutung – Die Durchführung einer S-LCA in der Luftfahrt rückt die sozialen Implikationen des Flugzeugprogramms in den Fokus und bietet eine Grundlage für eine allgemeine Diskussion über seine soziale Nachhaltigkeit.

Originalität – Dies scheint die erste Arbeit zum Thema S-LCA eines Flugzeugs oder Flugzeugprogramms zu sein.
