Résumé

L'industrie automobile est dans une tourmente, conjoncturelle, tout d'abord, avec un marché profondément affecté par le Covid, des pénuries de matériaux et composants et des clients désorientés ;structurelle, ensuite, avec la transition â marche forcée vers l'électrification. Cette double crise est a haut risque pour l'industrie automobile, mais l'alignement de l'action de l'ensemble des parties prenantes devrait permettre â la filiere française de rester dans la course pour l'automobile du futur.

Résumé

L'industrie automobile est a la croisée des chemins, car elle est soumise a une conjonction d'externalités d'une ampleur et d'une intensité rarement vues : absorption de toutes les crises récentes, celles du Covid et des semi-conducteurs, mais aussi celle de la hausse des prix de l'énergie. C'est celui de parvenir å intégrer ces techniques afin de parvenir a réinventer l'automobile de demain, une automobile connectée, robotisée et traitant automatiquement de grands volumes de données afin de progresser en intelligence, et de mettre celle-ci au service de l'humain, pour un usage réinventé de l'automobile et pour instaurer un systéme de mobilité plus durable. Il appelle ainsi a mieux cibler l'accompagnement des fournisseurs pour faire émerger une nouvelle génération d'ETI et aussi l'apparition de grands équipementiers leaders dans le monde de l'électrique, de l'hydrogene et, plus globalement, de l'automobile de demain. Il demande aussi que l'Europe se donne du temps pour s'adapter a la transition en protégeant temporairement, a l'instar des États-Unis, son marché intérieur.

Résumé

[...]the vehicle of the future must be considered within the broader framework of the mobility of the future, taking into account the entire value chain. Transforming our future into a sustainable future: planning for the automotive transition Didier Sepulchre de Condé, Mechanical industry The automotive industry is in turmoil, firstly because of the economic situation, with a market deeply affected by Covid, shortages of materials and components and disoriented customers;and secondly because of the structural situation, with the forced transition to electrification. The four paradoxes of the ecological transition of the European car industry Alois Kirchner, Former Director of Cabinet of the Minister for Industry The energy transition in the automotive sector is essential for achieving French and European climate objectives. [...]the actions implemented come up against four paradoxes, which must be overcome if this transition is to succeed: * the regulation on the reduction of CO2 emissions from the tank to the wheel, to the exclusion of other sources which now represent the majority of emissions from new vehicles;* the steering of vehicle traffic restrictions based on Crit'air stickers, leading to the prohibition of access to certain cities for vehicles that are more virtuous than others that are still allowed to enter;* the inability to implement policies to support the production of vehicles on European soil that are sufficiently powerful to halt the fall in associated jobs;a situation that benefits production sites that are not subject to the same environmental standards;* and the rising price of "green" vehicles, leading to a slowdown in the renewal of the fleet and the maintenance of a high level of pollution and carbon emissions.

Résumé

The recovery of materials and energy from end-of-life products is increasingly a fundamental factor in the sustainable development of various countries. Recovering metals from different types of waste is not only a practice in support of the environment, but is also a profitable economic activity. For this reason, exhausted automotive catalysts can become renewable sources of critical raw materials such as Pt, Pd, and Rh. However, recovering Pt and Pd from spent catalysts through an efficient, economical, and green method remains a challenge. This article presents a new leaching process for the hydrometallurgical recovery of Pt and Pd from exhausted automotive catalysts. The leaching solution consists of an aqueous mixture of hydrochloric acid, two organic acids (citric acid and acetic acid) and hydrogen peroxide. A complete factorial plan on two levels (2k) was performed in order to evaluate the main effects of the analyzed factors and their interactions. The factors that were presumed to be the most influential on the leaching of Pt and Pd were the concentrations of the different reagents and the reaction time. The optimal circumstances for achieving the largest recovery (over 80% Pt and 100% Pd) were achieved using the following conditions: a concentration of HCl of 5 M, a concentration of H2O2 of 10% wt./vol., a concentration of C2H4O2 of 10%vol./vol., and a reaction time of 3 h.

Résumé

Stoneware is a ceramic material with low porosity and high mechanical properties, such as the modulus of rupture. It is essentially made of clay, feldspar and quartz and is sintered to create a mixture of glass and crystalline phases. With the projected growth rate of the global ceramics market size and the country's development plan for 2023–2028, it is imperative that alternative raw materials for the manufacture of ceramic products be sourced so that the importation of these materials, such as feldspar, be minimized, if not eliminated. Cinder in the Philippines is mainly used as a filling material in pavements and residential areas. In this study, this resource is utilized as partial and full replacement of feldspar in a typical ternary diagram for stoneware production. Bars were formed from different formulations by the slip casting method and were sintered at 1200 °C. Physical and mechanical properties of the bars, such as shrinkage, loss on ignition, water absorption, apparent porosity and modulus of rupture were determined. Thermo-physical analyses were also carried out on the raw materials and on formulated powders. Meeting the requirements of the various quality standards for ceramics, the partial replacement of feldspar with black cinder (LF, LFBQ and LFBH) is feasible for wall and roof applications while full replacement of feldspar with black cinder (LB) is suitable for wider use as wall, floor, vitrified, industrial and roof tiles.

Résumé

My geologic research began at Carleton College. I studied heavy minerals in some midcontinent orthoquartzites, publishing my very first paper in American Mineralogist in 1954. As a master’s candidate at the University of Minnesota, I investigated igneous differentiation in a diabase-granophyre sill of the Duluth Gabbro Complex. Later, in a Ph.D. program at Johns Hopkins University, I became Joe Boyd’s apprentice at the Geophysical Laboratory (GL), and for a time was phase-equilibrium god of the Na-amphiboles. Doctoral research earned me an offer of a UCLA assistant professorship as a mineralogist in 1960. There, I continued pursuing amphibole P-T stability relations in lab and field. My glaucophane phase equilibrium research would later be found to have instead crystallized Na-magnesiorichterite. However, amphibole research led me to map field occurrences of HP-LT (high P-low T) blueschists of the Franciscan Complex. Thus, when plate tectonics emerged in the late 1960s, I was deep in the subduction zone. My recent studies focused on the petrology and geochemistry of oceanic crustal rocks, Californian calc-alkaline arcs, and coesite ± microdiamond-bearing crustal margin rocks in various parts of Eurasia. Other works treated global mineral resources and population, mineralogy and human health, and early Earth petrotectonic evolution. I tried to work on important problems, but mainly studied topics that fired my interest. For the future, I see the existential challenge facing humanity and the biosphere as the imperative to stop our overdrafting of mineral resources. This will require reaching a dynamic equilibrium between the use and replenishment of near-surface resources (i.e., nutrients) essential for life. Earth scientists are planetary stewards, so we must lead the way forward in life-supporting mineral usage, recycling, substitution, and dematerialization. In any event, sustainable development will soon return to the Earth’s Critical Zone of life because Mother Nature—the ruling terrestrial economist—abhors long-term overdrafting of resourcesRecently, a series of profound calamities have overwhelmed the World—the coronavirus pandemic, disruption of the global economy, and near-universal condemnation of the widespread, systemic abrogation of human rights/racial justice. Comparable challenges have emerged episodically ever since the rise of civilization. Such problems have been addressed over the millennia with varying degrees of success. However, human efforts have never achieved dynamic environmental equilibrium between consumption of Earth resources and rates of recharge. Sustainable development remains our long-term, existential threat..

Résumé

The OECD has long recognized the need to better understand how to reconcile the risks and benefits of data access and sharing to help governments reap the benefits of data-driven innovation. To guide policymaking, the OECD has produced over the last decade and a half a significant body of analytical work and legal instruments setting out principles and best practices to address sector-or domain-specific challenges in the governance of data. These Recommendations include: the Recommendation concerning Access to Research Data from Public Funding(2);the Recommendation for Enhanced Access and More Effective Use of Public Sector Information®;and the Recommendation on Health Data Governance®. In what appears to be the latest strong demonstration of its commitment to the issue, the OECD Council adopted in 2021, the Recommendation on Enhancing Access to and Sharing of Data (EASD Recommendation)®. Differently from the preceding ones, the EASD Recommendation provides an overarching set of principles and policy guidance to help governments reconcile potential risks and benefits and unlock the re-use of all types of data across and within sectors, jurisdictions, organisations, and communities. The aim of this paper is to put in context this significant body of work and set out the main policy issues addressed by these OECD Recommendations.

L'usage des réseaux sociaux en santé connaÎt un essor permanent dans une société de plus en plus connectée. Ces plateformes sont devenues de véritables outils dans le parcours de vie des patients. De la recherche d'informations à la constitution de communautés, les réseaux sociaux s'imposent comme un élément permanent du « parcours de soins numérique » des patients et des parties prenantes en santé. Cette production spontanée de données de la vie réelle fait l'objet d'une multitude de recherches à des fins de santé publique. Mais à l'ère annoncée du Métavers, plusieurs questionnements éthiques et sociétaux se posent autour de l'exploitation de ces données sensibles.Alternate :The use of social networks in healthcare is constantly growing withinin an increasingly connected society.

Résumé

La révolution numérique intervenue au cours des trente dernières années est à l'origine de très nombreuses mutations au plan économique et dans notre vie quotidienne. Internet qui en est le socle s'est bâti sur l'échange de données toujours plus importantes, mais surtout sur leur valorisation dans tous les champs : scientifique, sociétal, politique, artistique, ludique... L'information et la connaissance qu'elles rendent possibles constituent un actif qu'il s'agit aujourd'hui de protéger au regard de leur valeur intrinsèque, mais aussi des conséquences que peut induire, directement ou indirectement, leur utilisation. À l'image du numérique et comme toute autre innovation, l'émergence des données n'est pas neutre, représentant tour à tour un risque ou une opportunité, un remède ou un « poison ». La cybersécurité est une pratique et un champ industriel qui peuvent permettre de mesurer et de canaliser ces différentes alternatives, mais qu'il faut aussi appréhender sur le plan politique, au niveau national comme international, pour tenter d'en réguler les équilibres.Alternate :Digital revolution has induced massive economical transformations, since the last thirty years. Data exchange, thanks to the Internet has been cornerstone to this revolution, enhanced by their valuation in all domains: science, health, society, politics, arts, entertainment... Information and knowledge they produce become actual assets, to protect for their own value, as well as for consequences they can cause, directly or indirectly. Data emergence is not neutral, like other aspects of Digital and any innovation: as much a cure as a poison, they can lead to both risks and opportunities. Cybersecurity is a practice and an industrial sector that can allow gauging and marshalling such routes. In this context, political regulation and balances are needed, at both national and international.

Improving the efficiency of trucking (TR) in the conditions of a mining enterprise by means of developing recommendations aimed at enhancing reliability of the transport process. Methodology. To determine the factors influencing the reliability of TR the Functional Resonance Analysis ethod (hereinafter - FRAM) was used, which is based on the study on the functions of freight automobile transportation process with respect to six different aspects: time, control, output, resource, prerequisites, and entrance. Findings. The transport process of TR in the conditions of a mining enterprise is represented by five main functions: preparation of TR, supply of the truck for loading, loading of cargo, transportation and unloading of cargo at the destination point. For each function of the transport process TR we determined its variability as based on the accuracy and timeliness of the transport operation;identified factors that affect the reliability of the transport process, namely driver experience, administrative control, time of the transport operation, complexity of the transport operation, workplace ergonomics, workload and stress, the level of management support that may worsen the final result of goods delivery to the point of unloading. It is determined that preparation and transportation of cargo to the destination point is the least reliable function of TR transport process. This is due to the significant changeability and variability, a large number of production tasks and high variable standards of transport work. It is proposed to strengthen the control over the psychophysiological condition of the driver in order to improve the reliability of TR in the conditions of a mining enterprise and to reduce the probability of failures during the performance of transportation work. Originality. It consists in establishing the relationship between the functions and factors of the transport process of TR in the conditions of a mining enterprise, which allows assessment of the reliability level of the task in a timely manner. Practical value. It consists in a quantitative assessment of the impact of transportation process factors on the reliability of TR in the conditions of a mining enterprise.

Résumé

Dumping is one of the main unit operations of mining. Notwithstanding a long history of using large rear dump trucks in mining, little knowledge exists on the cascading behavior of the run-of-mine material during and after dumping. In order to better investigate this behavior, a method for generating high fidelity models (HFMs) of dump profiles was devised and investigated. This method involved using unmanned aerial vehicles with mounted cameras to generate photogrammetric models of dumps. Twenty-eight dump profiles were created from twenty-three drone flights. Their characteristics were presented and summarized. Four types of dump profiles were observed to exist. Factors that influence the determination of these profiles include the location of the truck relative to the dump crest, the movement of the underlying dump material during the dumping process and the differences in the dump profile prior to dumping. The HFMs created in this study could possibly be used for calibrating computer simulations of dumps to better match reality.

Résumé

Les industries culturelles et créatives (ICCs) constituent un véritable levier pour le développement économique des pays et contribuent à promouvoir la créativité des sociétés et à offrir des opportunités pour imaginer de nouveaux futurs. Avant de donner un aperçu global des ICCs, il est important d'avoir conscience de leur hétérogénéité eu égard à leur taille, leur secteur d'activité, leur situation géographique et aux cadres de gouvernance dans lesquels elles évoluent. Les ICCs sont aujourd'hui traversées par de profondes transformations mettant à mal leur développement, voire, pour certaines, leur pérennité. La pandémie de Covid-19 a bouleversé le secteur culturel à travers les mesures sanitaires mises en place pour ralentir la propagation du coronavirus. Cette crise a également induit une accélération du poids des plateformes numériques, avec l'émergence de pratiques culturelles alternatives ébranlant de façon structurelle la chaÎne de valeur des ICCs, qui, pour certaines, n'en tirent guère profit. Face à ces défis, il est indispensable d'oeuvrer à la création d'un environnement propice à la créativité, à l'innovation artistique et à la diversité des expressions culturelles, tout en accompagnant au mieux la transition numérique du secteur et en protégeant les libertés fondamentales.Alternate :The cultural and creative industries (CCIs) constitute a real lever for the economic development of countries and contribute to promoting the creativity of societies and offering opportunities to imagine new futures.

Résumé

This article presents the findings of an unsupervised field study conducted over 31 days in Argentina and Cuba in order to explore mobile QoE. We also analyzed the correspondence between the objective observations and users’ opinions to identify contextual conditions that could have influenced the study’s results. Using their own mobile devices in everyday contexts, 95 users from Argentina and Cuba interacted with CovidInfo app, thereby recording values for eight objective metrics as well as their opinions. The total data set collected consisted of 41,144 records. Analysis of the CovidInfo application yielded positive QoE results in both countries, as 88% and 70% of the objective metrics in Argentina and Cuba, respectively, were optimal. The main difference between the two countries is the type of connection: In Argentina, WiFi networks are predominant, while the trend in Cuba is mobile data connections.

Résumé

Carbon capture is among the most sustainable strategies to limit carbon dioxide emissions, which account for a large share of human impact on climate change and ecosystem destruction. This growing threat calls for novel solutions to reduce emissions on an industrial level. Carbon capture by amorphous solids is among the most reasonable options as it requires less energy when compared to other techniques and has comparatively lower development and maintenance costs. In this respect, the method of carbon dioxide adsorption by solids can be used in the long-term and on an industrial scale. Furthermore, certain sorbents are reusable, which makes their use for carbon capture economically justified and acquisition of natural resources full and sustainable. Clay minerals, which are a universally available and versatile material, are amidst such sorbents. These materials are capable of interlayer and surface adsorption of carbon dioxide. In addition, their modification allows to improve carbon dioxide adsorption capabilities even more. The aim of the review is to discuss the prospective of the most widely available clay minerals in the Baltic States for large-scale carbon dioxide emission reduction and to suggest suitable approaches for clay modification to improve carbon dioxide adsorption capacity.

Résumé

Microplastics (MPs) are considered an important stratigraphic indicator, or ‘technofossils’, of the Anthropocene. Research on MP abundance in the environment has gained much attention but the lack of a standardized procedure has hindered the comparability of the results. The development of an effective and efficient method of MP extraction from the matrix is crucial for the proper identification and quantifying analysis of MPs in environmental samples. The procedures of density separation used currently have various limitations: high cost of reagents, limited solution density range, hazardous reagents, or a combination of the above. In this research, a procedure based on density separation with the use of potassium formate water solution (H2O/KCOOH) in controlled conditions was performed. Experimental sediment mixtures, spiked with polyethylene (PE), polystyrene (PS), polyurethane (PUR) and polyethylene terephthalate (PET) particles were prepared and an extraction procedure was tested in the context of a weight-based quantitative analysis of MPs. This article discusses the effectiveness and safety of the method. It additionally provides new information on the interactions between MP particles and the mineral matter of the sediment. Results were acquired with the use of instrumental methods, namely thermogravimetry (TG), Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron microscopy and Energy Dispersive spectrometry (SEM/EDS), as well as X-ray fluorescence (XRF) analysis.
