Published: May 2024

The theoretical research is devoted to the improvement of the existing structures of shock absorbers, which ensure the recovery of mechanical energy into electrical energy with further useful use. First of all, an analysis of the use of different shock absorbers by drive type was performed. The advantages and disadvantages of each of them are established according to the criterion parameters of reliability, manufacturability and operation.

A refined classification of shock absorbers by type of kinematic connection and structural design is proposed. According to the proposed classification, the rational type of drive for creating new models of recuperative shock absorbers is determined to be hydraulic. According to the developed recommendations for choosing the shock absorber drive type, you can choose the drive type depending on the desired prevailing technical indicator.

The paper presents the results of a theoretical study of existing designs of recuperative damping systems. It has been established that, in addition to energy recovery, such damping systems provide improved damping and damping performance and allow the user to choose the desired mode of operation of the suspension. Analysis of existing designs of regenerative shock absorbers indicates better efficiency of systems with feedback. This type of communication is provided in most cases by using electronic measuring systems with a control unit, which greatly complicates and increases the cost of the design.

Based on the results of the theoretical analysis of the existing designs of recuperative shock absorbers of world manufacturers and developers, technical and technological requirements for new designs of recuperative shock absorbers were formed, which, in our opinion, are aimed at rationalization and optimization of the latter.

According to the developed technical and technological requirements, a basic design scheme of a recuperative damping system with hydrovalves for improving quality parameters was developed. The principle of operation of the quality valve with a profiled spool window is described
Väistyvien perillisten elämänkulku ja lounaissuomalaisten maatilojen perinnönjakostrategia 1700–1900
Authors: Laine Kirsi
Published: May 2024

Lounais-Suomen peltoviljelyalueella käytetty perinnönjakostrategia pyrki säilyttämään maatilat jakamattomina ja suosi vanhinta poikaa maatilan jatkajaksi. Perinnönjako kohteli perillisiä epätasa-arvoisesti, ja jatkajan sisaruksia uhkasi aleneva säätykierto. Tämä artikkeli käsittelee perinnönjakostrategian sosiaalisia seurauksia väistyvien perillisten kannalta. Jatkajien sisarusten elämänkulkuja seurataan Huittisissa ja Loimaalla 1700- ja 1800-luvuilla. Elämänkulkujen avulla esitetään, minkälaisia mahdollisuuksia ja vaihtoehtoja oli niillä maatilojen lapsilla, jotka eivät jatkaneet kotitilansa emäntänä tai isäntänä. Yli puolet väistyvistä perillisistä päätyi tilallisiksi eli samaan asemaan kuin vanhempansa. Väestönkasvua seurannut taloudellisen ja sosiaalisen eriarvoisuuden lisääntyminen tutkitulla ajalla vaikeutti tilallisasemaan pääsemistä, ja muutos vaikutti erityisesti poikien mahdollisuuksiin. Lisäksi väistyvien perillisten elämään vaikutti kotitilan kameraalinen koko. Suurten tilojen lapsilla oli parhaat mahdollisuudet sosiaalisen aseman säilyttämiseen. Tilan jakaminen perillisten kesken mahdollisti lyhyellä tähtäimellä usealle perilliselle aseman tilallisena, mutta heikensi tilojen talouden perustaa ja siten myös seuraavan sukupolven mahdollisuuksia sijoittua sosiaalisesti hyvään asemaan. 1800-luvulla perinnönjakokäytäntö tuki maanomistuksen keskittymistä, mikä entisestään kiihdytti maaseutuväestön eriarvoistumisen kierrettä.
The article focuses on the inheritance practice of peasant farms and its social consequences in Southwest Finland. Holdings were kept undivided and the eldest son had priority in order of succession of the farm. The possibilities and options of other children are studied by following the life course of successor’s siblings in Huittinen and Loimaa in the 18th and 19th centuries. More than a half of the non-succeeding siblings managed to become farmers in some other way. Population growth increased economic and social inequality during the period and made it more difficult to maintain the social position, especially for sons. In addition to gender, social success was influenced by the economic features of the home farm. Children from large farms maintained social position most likely. The partitioning of the farm between two or more heirs weakened the economy of the farms and the possibilities of the next generation to reach a socially desirable position. Instead, the possibilities of the offspring were improved by acquiring several holdings, so that the concentration of land ownership accelerated the cycle of inequality.
Subgroup detection in linear growth curve models with generalized linear mixed model (GLMM) trees
Authors: Fokkema Marjolein , Zeileis Achim
Published: May 2024

Growth curve models are popular tools for studying the development of a response variable within subjects over time. Heterogeneity between subjects is common in such models, and researchers are typically interested in explaining or predicting this heterogeneity. We show how generalized linear mixed-effects model (GLMM) trees can be used to identify subgroups with different trajectories in linear growth curve models. Originally developed for clustered cross-sectional data, GLMM trees are extended here to longitudinal data. The resulting extended GLMM trees are directly applicable to growth curve models as an important special case. In simulated and real-world data, we assess performance of the extensions and compare against other partitioning methods for growth curve models. Extended GLMM trees perform more accurately than the original algorithm and LongCART, and similarly accurate compared to structural equation model (SEM) trees. In addition, GLMM trees allow for modeling both discrete and continuous time series, are less sensitive to (mis-)specification of the random-effects structure and are much faster to compute.
Estimating the proportions and latencies of reaction time outliers: A pooling method and case study of lexical decision tasks
Authors: Miller Jeff
Published: May 2024

A methodological problem in most reaction time (RT) studies is that some measured RTs may be outliers—that is, they may be very fast or very slow for reasons unconnected to the task-related processing of interest. Numerous ad hoc methods have been suggested to discriminate between such outliers and the valid RTs of interest, but it is extremely difficult to determine how well these methods work in practice because virtually nothing is known about the actual characteristics of outliers in real RT datasets. This article proposes a new method of pooling cumulative distribution function values for examining empirical RT distributions to assess both the proportions of outliers and their latencies relative to those of the valid RTs. As the method is developed, its strengths and weaknesses are examined using simulations based on previously suggested ad hoc models for RT outliers with particular assumed proportions and distributions of valid RTs and outliers. The method is then applied to several large RT datasets from lexical decision tasks, and the results provide the first empirically based description of outlier RTs. For these datasets, fewer than 1% of the RTs seem to be outliers, and the median outlier latency appears to be approximately 4–6 standard deviations of RT above the mean of the valid RT distribution.

Comparative analysis of the ultrastructure and adhesive secretion pathways of different smooth attachment pads of the stick insect Medauroidea extradentata (Phasmatodea)
Authors: Thomas Julian , Gorb Stanislav N , Büscher Thies H
Published: May 2024

The mechanism by which insects achieve attachment and locomotion across diverse substrates has long intrigued scientists, prompting extensive research on the functional morphology of attachment pads. In stick insects, attachment and locomotion are facilitated by two distinct types of smooth cuticular attachment pads: the primary adhesion force-generating arolium and the friction force-generating euplantulae. They are both supported by an adhesive secretion delivered into the interspace between the attachment pads and the substrate. In this study, we analysed and compared internal morphology, material composition and ultrastructure, as well as the transportation pathways in both adhesive organs in the stick insect Medauroidea extradentata using scanning electron microscopy, micro-computed tomography, light microscopy, and confocal laser scanning microscopy. Our observations revealed structural differences between both attachment pads, reflecting their distinct functionality. Furthermore, our results delineate a potential pathway for adhesive secretions, originating from exocrine epidermal cells and traversing various layers before reaching the surface. Within the attachment pad, the fluid may influence the viscoelastic properties of the pad and control the attachment/detachment process. Understanding the material composition of attachment pads and the distribution process of the adhesive secretion can potentially aid in the development of more effective artificial attachment systems.

Published: May 2024

Withania somnifera also known as Ashwagandha used as rasayana (tonic) in Ayurvedic system of medicine. It is widely considered as Indian Ginseng and possesses medicinal properties like adaptogenic, antistress, anxiolytic, anti-arthritic, anti-inflammatory etc. There is long history of microbes having stable symbiotic relationship with plants aiding them in growth and survival. This endophytic relationship is also been observed in medicinal plants. This study is an attempt to observe the biodiversity of endophytic fungal community in Withania somnifera and to understand their colonization. The study was aimed to isolate endophytes from different organs of Withania somnifera with seasonal variations. A total of 131 endophytic fungi were isolated from 450 explants from different organs like leaves, stems and roots of W. somnifera. The overall colonization rate of endophytes in winter, summer and monsoon were 42.67%, 7.33% and 37.33% respectively. Among the identified isolates, most abundant and frequently isolated genera were Alternaria, Fusarium and Chaetomium sps. The dominant species isolated in winter were the Fusarium moniliformae and Chaetomium globosum from leaves with 17.24% and 13.79% dominant frequency, respectively. While Alternaria raphani and Chaetomium globosum were most dominant species in summer from leaves with 40% dominant density. In the monsoon, Microsporum ferruginem was the most dominant species isolated from leaves and stem with 61.29% and 42.86%, respectively. The most recurring endophytic species of Ascomycetes group were Alternaria alternata and Chaetomium globosum seen in all seasons.

Published: May 2024

This article develops MacEachren’s summary of contemporary approaches to cartography as communication as a one-way flow of map information. The Hong Kong experience shows that large-scale government survey maps can be used by non-specialists to (re)discover and identify, for conservation planning purposes, very small Second World War defence structures not annotated on those maps. By accumulating information and field studies, non-specialists can produce specialist maps as a contribution to conservation planning. The issues of a market for military heritage buildings and the actual role the government cartographer played in conservation mapping are discussed.

Katachi (形): Decoding the Imprints of Past Star Formation on Present-day Morphology in Galaxies with Interpretable CNNs*

Published: May 2024

The physical processes responsible for shaping how galaxies form and quench over time leave imprints on both the spatial (galaxy morphology) and temporal (star formation history; SFH) tracers that we use to study galaxies. While the morphology–SFR connection is well studied, the correlation with past star formation activity is not as well understood. To quantify this, we present Katachi (形), an interpretable convolutional neural network framework that learns the connection between the factors regulating star formation in galaxies on different spatial and temporal scales. Katachi is trained on 9904 galaxies at 0.02 < z < 0.1 in the SDSS-IV MaNGA DR17 sample to predict stellar mass (M
*; root mean square error (RSME) 0.22 dex), current star formation rate (SFR; RMSE 0.31 dex), and half-mass time (t
50; RMSE 0.23 dex). This information allows us to reconstruct nonparametric SFHs for each galaxy from gri imaging alone. To quantify the morphological features informing the SFH predictions, we use SHAP (SHapley Additive exPlanations). We recover the expected trends of M
* governed by the growth of galaxy bulges, as well as those of SFR correlating with spiral arms and other star-forming regions. We also find that the SHAP maps of D4000 are more complex than those of M
* and SFR, and that morphology is correlated with t
50 even at fixed mass and SFR. Katachi serves as a scalable public framework to predict galaxy properties from large imaging surveys including Rubin, Roman, and Euclid, with large data sets of high signal-to-noise ratio imaging across limited photometric bands.
Relation between the Local Width and Linear Halo Mass Density of Cosmic Filaments
Authors: Zhu Weishan , Wang Tian-Rui , Zhang Fupeng , Zheng Yi , Feng Long-Long
Published: May 2024

Large-scale cosmic filaments may have played an important role in shaping the properties of galaxies. Meanwhile, cosmic filaments are believed to harbor a substantial portion of the missing baryons at redshift z < 2. To inspect the role of filaments in these issues, many properties of filaments need to be examined, including their lengths, thicknesses, and density profiles. However, measuring some of these properties poses challenges. This study concentrates on estimating filament width/thickness, investigating potential correlations between the local width of filaments and the properties of dark matter halos within filaments. We find that the local width of filaments generally increases with the mass of dark matter halos embedded in filaments per unit length, roughly following a second-order polynomial, although with notable scatter. We probe and discuss means that may refine our findings. After further verification and improvements, this relation could be applied to filament samples constructed from the observed galaxy distribution, aiding in understanding the roles of cosmic filaments in galaxy evolution and uncovering the missing baryons.
Strong Fractionation of Deuterium and Helium in Sub-Neptune Atmospheres along the Radius Valley
Authors: Cherubim Collin , Wordsworth Robin , Hu Renyu , Shkolnik Evgenya
Published: May 2024

We simulate atmospheric fractionation in escaping planetary atmospheres using IsoFATE, a new open-source numerical model. We expand the parameter space studied previously to planets with tenuous atmospheres that exhibit the greatest helium and deuterium enhancement. We simulate the effects of extreme-ultraviolet-driven photoevaporation and core-powered mass loss on deuterium–hydrogen and helium–hydrogen fractionation of sub-Neptune atmospheres around G, K, and M stars. Our simulations predict prominent populations of deuterium- and helium-enhanced planets along the upper edge of the radius valley with mean equilibrium temperatures of ≈370 K and as low as 150 K across stellar types. We find that fractionation is mechanism dependent, so constraining He/H and D/H abundances in sub-Neptune atmospheres offers a unique strategy to investigate the origin of the radius valley around low-mass stars. Fractionation is also strongly dependent on retained atmospheric mass, offering a proxy for planetary surface pressure as well as a way to distinguish between desiccated enveloped terrestrials and water worlds. Deuterium-enhanced planets tend to be helium dominated and CH4 depleted, providing a promising strategy to observe HDO in the 3.7 μm window. We present a list of promising targets for observational follow-up.

Published: May 2024

We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using Wide-field Infrared Survey Explorer/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 projects (hereafter BYW). This sample represents an ∼60% increase in the number of known M + T systems, and allows us to probe the most extreme products of binary/planetary system formation, a discovery space made available by the CatWISE2020 catalog and the BYW effort. Highlights among the sample are WISEP J075108.79-763449.6, a previously known T9 thought to be old due to its spectral energy distribution, which was found by Zhang et al. (2021b) to be part of a common proper motion pair with L34-26 A, a well-studied young M3 V star within 10 pc of the Sun; CWISE J054129.32-745021.5 B and 2MASS J05581644-4501559 B, two T8 dwarfs possibly associated with the very fast-rotating M4 V stars CWISE J054129.32745021.5 A and 2MASS J05581644-4501559 A; and UCAC3 52-1038 B, which is among the widest late-T companions to main-sequence stars, with a projected separation of ∼7100 au. The new benchmarks presented here are prime JWST targets, and can help us place strong constraints on the formation and evolution theory of substellar objects as well as on atmospheric models for these cold exoplanet analogs.
Modified Temperature–Redshift Relation and Ultra-high-energy Cosmic Ray Propagation
Authors: Meinert Janning , Morejón Leonel , Sandrock Alexander , Eichmann Björn , Kreidelmeyer Jonas , Kampert Karl-Heinz
Published: May 2024

We reexamine the interactions of ultra-high-energy cosmic rays (UHECRs) with photons from the cosmic microwave background (CMB) under a changed, locally nonlinear temperature–redshift relation T(z). This changed temperature–redshift relation has recently been suggested by the postulate of subjecting thermalized and isotropic photon gases such as the CMB to an SU(2) rather than a U(1) gauge group. This modification of ΛCDM is called SU(2)CMB, and some cosmological parameters obtained by SU(2)CMB seem to be in better agreement with local measurements of the same quantities, in particular H
0 and S8. In this work, we apply the reduced CMB photon density under SU(2)CMB to the propagation of UHECRs. This leads to a higher UHECR flux just below the ankle in the cosmic ray spectrum and slightly more cosmogenic neutrinos under otherwise equal conditions for emission and propagation. Most prominently, the proton flux is significantly increased below the ankle (5 × 1018 eV) for hard injection spectra and without considering the effects of magnetic fields. The reduction in CMB photon density also favors a decreased cosmic ray source evolution than the best fit using ΛCDM. In consequence, it seems that SU(2)CMB favors sources that evolve like the star formation rate, such as starburst galaxies and gamma-ray bursts, over active galactic nuclei as origins of UHECRs. We conclude that the question about the nature of primary sources of UHECRs is directly affected by the assumed temperature–redshift relation of the CMB.
Skeletal Kinetics Reduction for Astrophysical Reaction Networks
Authors: Nouri A. G. , Liu Y. , Givi P. , Babaee H. , Livescu D.
Published: May 2024

A novel methodology is developed to extract accurate skeletal reaction models for nuclear combustion. Local sensitivities of isotope mass fractions with respect to reaction rates are modeled based on the forced optimally time-dependent (f-OTD) scheme. These sensitivities are then analyzed temporally to generate skeletal models. The methodology is demonstrated by conducting skeletal reduction of constant density and temperature burning of carbon and oxygen relevant to Type Ia supernovae (SNe Ia). The 495-isotopes Torch model is chosen as the detailed reaction network. A map of maximum production of 56Ni in SNe Ia is produced for different temperatures, densities, and proton-to-neutron ratios. The f-OTD simulations and the sensitivity analyses are then performed with initial conditions from this map. A series of skeletal models are derived and their performances are assessed by comparison against currently existing skeletal models. Previous models have been constructed intuitively by assuming the dominance of α-chain reactions. The comparison of the newly generated skeletal models against previous models is based on the predicted energy release and 44Ti and 56Ni abundances by each model. The consequences of y

The Evolution of Stellar X-Ray Activity and Angular Momentum as Seen by eROSITA, TESS, and Gaia
Authors: Stassun Keivan G. , Kounkel Marina
Published: May 2024

We have assembled a sample of ∼8200 stars with spectral types F5V–M5V, all having directly measured X-ray luminosities from eROSITA and rotation periods from TESS and having empirically estimated ages via their membership in stellar clusters and groups identified in Gaia astrometry (ages 3–500 Myr). This is the largest such study sample yet assembled for the purpose of empirically constraining the evolution of rotationally driven stellar X-ray activity. We observe rotation–age–activity correlations that are qualitatively as expected: stars of a given spectral type spin down with age, and they become less X-ray active as they do so. We provide simple functional representations of these empirical relationships that predict X-ray luminosity from basic observables to within 0.3 dex. Interestingly, we find that the rotation–activity relationship is far simpler and more monotonic in form when expressed in terms of stellar angular momentum instead of rotation period. We discuss how this finding may relate to the long-established idea that rotation–activity relationships are mediated by stellar structure (e.g., convective turnover time, surface area). Finally, we provide an empirical relation that predicts stellar angular momentum from basic observables, without requiring a direct measurement of stellar rotation, to within 0.5 dex.
Cannibals in PARADISE: The Effect of Merging Interplanetary Shocks on Solar Energetic Particle Events

Gradual solar energetic particle (SEP) events are associated with shocks driven by coronal mass ejections (CMEs). The merging of two CMEs (so-called cannibalistic CMEs) and the interaction of their associated shocks has been linked to some of the most powerful solar storms ever recorded. Multiple studies have focused on the observational aspects of these SEP events, yet only a handful have focused on modeling similar CME–CME interactions in the heliosphere using advanced magnetohydrodynamic (MHD) models. This work presents, to our knowledge, the first modeling results of a fully time-dependent 3D simulation that captures both the interaction of two CMEs and its effect on the acceleration and transport of SEPs. This is achieved by using an MHD model for the solar wind and CME propagation together with an integrated SEP model. We perform different simulations and compare the behavior of the energetic protons in three different solar wind environments, where a combination of two SEP-accelerating CMEs are modeled. We find that particle acceleration is significantly affected by the presence of both CMEs in the simulation. Initially, less efficient acceleration results in lower-energy particles. However, as the CMEs converge and their shocks eventually merge, particle acceleration is significantly enhanced through multiple acceleration processes between CME-driven shocks, resulting in higher particle intensities and energy levels.
Nanopore duplex sequencing as an alternative to Illumina MiSeq sequencing for eDNA-based biomonitoring of coastal aquaculture impacts

Oxford Nanopore Technologies has recently launched a duplex sequencing strategy and announced an improved error rate which is in a similar order of magnitude as Illumina sequencing. We therefore conducted a pilot study to assess whether Nanopore duplex sequencing has potential to be used as a technology in eDNA-based marine biomonitoring. Specifically, we investigated bacterial communities of sediment samples collected from Atlantic salmon (Salmo salar) aquaculture installations and compared the ecological trends obtained from short Illumina (V3-V4 region of the 16S rRNA gene) and long Nanopore (full length 16S rRNA gene) sequence reads. The obtained duplex rate of Nanopore amplicon reads with a Phred score ≥ 30 was 36%, notably higher compared to previous reports from bacterial genome sequencing. When inferring alpha- and beta-diversity from Illumina ASVs and Nanopore OTUs, we found highly congruent ecological patterns. Only when collating ASVs and OTUs across taxonomic ranks, beta-diversity analyses of Illumina-data slightly changed, due to the difficulties to assign a taxonomy to short sequence reads. While on family rank, both sequence datasets had good agreement, genus-assignments of Illumina data were critical, resulting in higher disagreement between the two protocols. Our data provide evidence that eDNA-based monitoring of aquaculture-related environmental impacts could equally well be conducted with the improved Nanopore duplex sequencing. We discuss to what extent eDNA-based biomonitoring could benefit from long-read information.

Tea plant is one of the most important commercial crops worldwide. The Didymellaceae fungi can cause leaf blight disease of tea plant. In this study, 240 isolates were isolated from tea plant leaves of 10 provinces in China. Combined with multi-locus (ITS, LSU, RPB2 and TUB2) phylogenetic analysis and morphological characteristics, these isolates were identified as 25 species of six genera in Didymellaceae, including 19 known species Didymella coffeae-arabicae, D. pomorum, D. segeticola, D. sinensis, Epicoccum catenisporum, E. dendrobii, E. draconis, E. italicum, E. latusicollum, E. mackenziei, E. oryzae, E. poaceicola, E. rosae, E. sorghinum, E. tobaicum, Neoascochyta mortariensis, Paraboeremia litseae, Remotididymella anemophila and Stagonosporopsis caricae, of which 15 species were new record species and six novel species, named D. yunnanensis, E. anhuiense, E. jingdongense, E. puerense, N. yunnanensis and N. zhejiangensis. Amongst all isolates, D. segeticola was the most dominant species. Pathogenicity tests on tea plant leaves showed that E. anhuiense had the strongest virulence, while E. puerense had the weakest virulence. Besides, D. pomorum, D. yunnanensis, E. dendrobii, E. italicum, E. jingdongense, E. mackenziei, E. oryzae, E. rosae, E. tobaicum, N. mortariensis, N. yunnanensis, N. zhejiangensis and R. anemophila were non-pathogenic to the tea plant.
Suicide et carrière de l’homme disqualifié : une appréhension dynamique du « déficit d’intégration » durkheimien à partir de cas d’agriculteurs
Authors: Deffontaines Nicolas
Published: May 2024

Les représentations communes associées aux suicides d’agriculteurs consacrent la figure de l’homme seul face aux difficultés économiques. Les agriculteurs seraient ainsi un cas d’étude privilégié pour penser le suicide égoïste, défini par Durkheim comme étant lié à un « déficit d’intégration ». Cette notion est cependant considérée comme difficilement opératoire parce qu’elle serait appréhendée de façon trop statique du fait de la pauvreté des données en matière de suicide. À partir d’une enquête qualitative construisant des trajectoires d’agriculteurs suicidés, cet article montre que le suicide égoïste peut être pensé comme le point ultime d’une carrière par laquelle l’individu se trouve disqualifié de l’ensemble des scènes sociales dans lesquelles il s’inscrivait.
Rester insensible au suicide de victimes de cybersexisme ? Analyse des répercussions du travail réputationnel posthume à travers deux cas marquants des années 2010
Authors: Déage Margot
Published: May 2024

La relation entre le cybersexisme et le suicide est souvent perçue comme inéluctable, malgré sa rareté statistique. L’analyse de deux cas de suicide de jeunes femmes, médiatisés au début de la prévention contre le harcèlement en France, révèle que le travail réputationnel entrepris par l’entourage oriente la perception des violences dénoncées. Dans le premier cas, la famille invoque des troubles mentaux chez la victime pour la décrédibiliser. Dans le second, la mère recourt à l’émotion du deuil pour réhabiliter la mémoire de sa fille et en faire un symbole de la lutte contre le harcèlement. Ces exemples ouvrent une réflexion sur la notion de suicide fataliste de Durkheim à la lumière du genre.

Le projet néolibéral, qui cherche à faire prévaloir le calcul d’intérêt sur la solidarité, informe aussi le management des entreprises. Réduisant l’activité du salarié à sa fonction instrumentale, il méconnaît l’appartenance à un collectif et le souci du travail bien fait.
Le sacrifice de l’ homo œconomicus
Authors: Marzolf Hedwig
Published: May 2024

Le néolibéralisme a pris un virage sacrificiel suite à la crise de 2008 : alors qu’il promouvait le calcul d’intérêt, il prône désormais une forme éthico-religieuse de désintérêt, transformant les individus en soldats au service de l’économie. On peut lui opposer le droit humain à l’indépendance économique.
