This paper discusses the relevance of using physical situations to introduce the concept of angles at elementary school. We compare the effectiveness of two geometry teaching sequences. In the first one (physical sequence), the pupils learned the angle concept by experimenting on the playground (i.e. mesospace) and then modelling the situation. In the second one (paper-and-pencil sequence), the pupils worked solely in the space of a sheet of paper (i.e. microspace). In both sequences, pupils compared areas of space delineated by an angle between two directions. Pupils in two Grade 3 classes were exposed to one of the two teaching sequences. The unfolding of these sequences was videotaped and analyzed, and the pupils were tested individually, before and after teaching, to measure each sequence's effectiveness. Results showed that both sequences are effective to grasp the angle concept: Most pupils overcame the common erroneous conception of comparing angles' sides' lengths instead of angle openness. The comparison of areas of space delineated by an angle between two infinite directions, which is the two sequences' common core, seems to be the key factor underlying angle conceptualization. This paper ends with a discussion of these results' teaching implications and the merits of each sequence.

Schools are ideal settings to promote adolescent physical activity (PA), yet school-based interventions have shown limited long-term impact. This position paper presents key issues surrounding school-based PA interventions. Collaborative conceptual thinking drawing on multi-author expertise and available evidence advanced our understanding and opinion. Key arguments: 1) the adoption of a systems approach, which maximizes partnership action and leverages policy, is crucial for understanding the complexities of implementing whole-school programs; 2) a reorientation to an assets perspective optimizes existing strengths and resources allowing greater emphasis on the full range of physical, cognitive, emotional and social benefits that PA provides, and 3) a move beyond traditional positivist research designs to advance our knowledge of what works better, for whom and in what context is needed for greater progress We provide suggestions, specifically advocating for systems approaches, as a realistic way to improve how we support PA in schools in the future.

Introduction: Military operations are no longer limited to the application of counterterrorism and counterinsurgency strategies; they are now characterized by hybrid, irregular, and unconventional features. While some authors have indicated the need for medical support to adapt to these new modes of military operations, they have focused mainly on the tactical level of care on the battlefield. As Sun Tzu states, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat," further proposals are still needed on the application of both medical tactics and medical strategies in irregular warfare., Methods: Medical experts from the French Special Operations Forces (SOF) Medical Command have identified specific medical challenges that special operations face in the context of the current transformation of armed confrontations into irregular warfare., Results: This position paper presents original tactical medical proposals for improving medical support in irregular warfare, ranging from the definition of a Primary-Alternate-Contingency-Emergency medical plan to the promotion of telemedical support. Original strategic medical proposals have highlighted the importance of recognizing medical issues in irregular warfare, including the medical actions carried out through and with local partners and the multiple approaches to countering medical threats., Conclusion: The SOF medical community must be closely involved with and facilitate the responses to the shift to irregular warfare. International collaboration and interoperability are more necessary than ever, as they will enable a more effective combination of good medicine with both good tactics and good strategies. These perspectives can also be extended to improve medical care in the conventional armed forces and austere civilian settings., Level of Evidence: Therapeutic/Care Management; Level V., (Copyright © 2024 The Author(s).

Low-density lipoprotein cholesterol has been established as a powerful cardiovascular risk factor; its reduction provides a clinical benefit in primary cardiovascular prevention, irrespective of the characteristics of the patients treated. It is useful to tailor low-density lipoprotein cholesterol targets according to the magnitude of cardiovascular risk (low, high or very high) in order to reduce the cardiovascular risk as fully as possible. In order to provide a uniform approach, it is necessary to propose recommendations for good practice, defining strategies for reducing low-density lipoprotein cholesterol. It is also necessary to know their merits, to analyse their practical limits and to propose adaptations, taking into account limitations and national specifics. This position paper aims to analyse the contribution and limits, as well as the adaptation to French practice, of 2019 and 2021 European Society of Cardiology recommendations for the management of lipid variables and cardiovascular prevention., (Copyright © 2024 Elsevier Masson SAS.

Introduction: We report an investigation on collaboration practices in research papers published in the most prestigious English-medium astrophysics journals. Method: We propose an evaluation method based on three numerical indicators to study and compare, in absolute terms, three different types of collaboration (international, national and local) and authors' mobility on the basis of co-authorship. Analysis: We analysed 300 randomly selected research papers in three different time periods and used the student's t-test to determine whether the paired two-sample differences observed were statistically significant or not. Results: International collaboration is more common than national and local collaboration. International, national and local authors' mobility and intra-national collaboration do not seriously affect the indicators of the principal levels of collaboration. International collaboration and authors' mobility are more relevant for authors publishing in European journals, whereas national and intra-national collaboration and national mobility are more important for authors publishing in US journals. Conclusions: We explain the observed differences and patterns in terms of the specific scope of each journal and the socio-economic and political situation in both geographic contexts (Europe and the USA). Our study provides a global picture of collaboration practices in astrophysics and its possible application to many other sciences and fields would undoubtedly help bring into focus the really big issues for overall research management and policy.

With the exception of the renowned Marquis de Lafayette and, to a lesser extent, General Rochambeau and Admiral de Grasse, French soldiers and officers have historically received little attention in the literary of the American War for Independence. This is due to a number of factors, including restricted or closed access to private archival collections in France. This essay will demonstrate that it is possible, under certain conditions, to study personal, unpublished source material of "forgotten" French officers who participated in the American Revolutionary War, thereby providing new opportunities for research into early American history. To demonstrate the historical significance of such materials, this paper will concentrate on the (mainly) unpublished papers of François-Jean de Chastellux (1734-1788), an influential major general who served directly under Rochambeau. The Chastellux family has preserved his private papers for more than 240 years in their Château de Chastellux. This article details the contents of this private archive as well as the history of its creation and preservation. Additionally, the existence of Chastellux's archive raises questions about the possible existence of similar unpublished French archival collections, which may also offer new perspectives on the American Revolutionary War. Furthermore, in the contemporary digital era, families that choose to preserve their records in private archives may now make them digitally accessible to the academic community. This introduces new circumstances and opportunities for the access and translation of previously inaccessible information. [ABSTRACT FROM AUTHOR]

Bisphenol A (BPA) is a high-production-volume chemical with endocrine disrupting properties commonly used as color developer in thermal paper. Concerns about the potential hazards of human BPA exposure have led to the increasing utilization of alternatives such as bisphenol S (BPS) and bisphenol F (BPF). This study was designed to assess: (i) BPA, BPS, and BPF concentrations in 112 thermal paper receipts from Brazil, France, and Spain by liquid chromatography coupled to mass spectrometry (LC-MS); and (ii) hormone-like activities of these receipts using two receptor-specific bioassays, the E-Screen for (anti-)estrogenicity and PALM luciferase assay for (anti-)androgenicity. BPA was present in 95.3% of receipts from Spain, 90.9% of those from Brazil, and 51.1% of those from France at concentrations up to 20.27 mg/g of paper. Only two samples from Brazil, two from Spain, and ten from France had a BPS concentration ranging from 6.46 to 13.29 mg/g; no BPA or BPS was detected in 27.7% of French samples. No BPF was detected in any receipt. Estrogenic activity was observed in all samples from Brazil and Spain and in 74.5% of those from France. Anti-androgenic activity was observed in > 90% of samples from Brazil and Spain and in 53.2% of those from France. Only 25.5% of French samples were negative for both estrogenic and anti-androgenic activity. Estrogenic and anti-androgenic activities per gram of paper were up to 1.411 µM estradiol (E 2 ) equivalent units (E 2 eq) and up to 359.5 mM procymidone equivalent units (Proceq), respectively. BPA but not BPS concentrations were positively correlated with both estrogenic and anti-androgenic activities. BPA still dominates the thermal paper market in Brazil and Spain, and BPS appears to be one of the main alternatives in France. There is an urgent need to evaluate the safety of alternatives proposed to replace BPA as developer in thermal printing. The large proportion of samples with hormonal activity calls for the adoption of preventive measures., (Copyright © 2018 Elsevier Inc. All rights reserved.)

This paper discusses key themes of the 15th biennial conference of the Association for Language Awareness (2020), with a focus on increasing digital engagement in language education. The COVID-19 pandemic occasioned an abrupt transition to emergency remote language teaching and learning (ERLTL) worldwide. The ALA 2020 conference was also affected by this transition; originally planned as a located conference in Geelong, Australia, it was eventually held online, a first in ALA's conference history. The current paper engages with contemporary debates of language teaching and learning in two ways. Firstly, it traces recent discussions by presenting key findings from five papers given at the conference, and secondly, via a scoping review of literature focusing on critical lessons from the pandemic regarding language teaching and learning. The review captures recent research from the Australasian region. Key debates identified in the literature include the needs of teachers and learners during the transition to online learning, and how student engagement was affected. The literatures highlight that both educators and students have been developing new practices in teaching and learning resulting from the shift to online and blended modes, which may continue to shape language education and new pedagogies in the future.

A growing number of schools are embracing new mobile technologies, such as iPads, with little (or no) prior empirical proof of their usability. We investigated whether iPads, which allow children to write and draw with their fingers without the need of a pen, are relevant devices for drawing activities at elementary school. A within-participants design was used to compare routine drawings produced by 46 elementary schoolchildren with pen on paper (standard condition) and fingertip on screen (iPad condition). Results revealed a significant effect of drawing condition on graphic scores, with lower scores in the iPad condition than in the standard condition. The finding that finger drawings were slightly poorer than pen drawings can be ascribed to the shift from distal to more proximal control of the drawing movements.

We analyze the role of institutional founding conditions and institutional legacy for universities' self-representation in terms of diversity. Based on 374 universities located in the Czech Republic, France, Germany, Hungary, Italy, and Poland, we can differentiate between a more idealistic understanding (logic of inclusion and equality) and a more market-oriented understanding (market logic) of diversity. Our findings show that the founding phase has no significant effect on the likelihood of a university focusing on a market-oriented understanding of diversity--however, we observe an imprinting effect with respect to the adoption of a diversity statement in general and an equity-oriented statement. Moreover, our findings show that there is a socialistic heritage for universities in Central and Eastern European (CEE) countries that is at work and still influences universities' understandings of diversity today.

The paper provides empirical results on the part of grey literature in the French national open repository HAL. The results are based on a quantitative analysis of 973,968 deposits from 1,272 research laboratories affiliated the ten most important research universities in France (IDEX program). 35% of all deposits (documents and records) are grey literature. The main types of these items are conference papers (71%), PhD theses (11%) and preprints and working papers (8%). Their overall accessibility (degree of openness) is 37%, which is higher than commercial publications. Differences between document types, disciplines and institution are described. Further research is needed for a better understanding of how research laboratories are handling grey literature (licensing ...). A follow-up study in 2021 will provide this insight.

(1) Background: The main basis for the public recognition of the merits of scientists has always been the system of scientific publications and citations. Our goal is to identify and analyze the most cited articles in the Public, Environmental & Occupational Health category. (2) Methods: We searched the Web of Science for all articles published in the "Public, Environmental & Occupational Health" category up to March 2022 and selected the 100 most cited articles. We recorded the number of citations, the journal, the year of publication, quartile, impact factor, institution, country, authors, topic, type of publication and collaborations. (3) Results: 926,665 documents were analyzed. The top 100 had 401,620 citations. The journal with the most articles was the Journal of Clinical Epidemiology and the one with the highest number of citations was Medical Care. The year with the highest number of articles in the top 100 was 1998. The country with the highest percentage of publications was the USA and the most productive institution was Harvard. The most frequent keywords were bias, quality, and extension. The largest collaboration node was between the USA, Canada, Germany, Spain, Australia, France, and Sweden. (4) Conclusions: This bibliometric study on Public, Environmental & Occupational Health provides valuable information not only to identify topics of interest in the analyzed category, but also to identify the differences in the topics they study.

Background: The objective was to describe a possible cancer mortality risk in relation with the occupational exposure within an International study co-ordinated by the International Agency for Research on Cancer., Methods: An epidemiological cohort study was set up to assess the mortality in four French pulp and paper companies. The four cohorts were followed up from January 1st 1968 to December 31st 1992. The causes of death were ascertained by matching with the national file of causes of death., Results: The full cohort consisted in 5,529 men and 876 women. The total numbers of subjects deceased between 1968 and 1992 were respectively 708 and 34. Causes of death could be traced for 98%. The observed mortality was significantly lower than the expected for all causes of deaths (SMR = 0.86) as well for all deaths by cancer (SMR = 0.87). The analysis by departments showed an excess mortality by cancer of the pancreas in the wood preparation department (SMR = 3.14) as well as in the paper production department (SMR = 2.04)., Conclusions: In absence of any prior hypothesis, it is difficult to assign an occupational origin to these observed excesses. The future results of the international study will enable us to interpret these results more precisely.

The article presents information on the restoration technique through paper splitting in reconstructing historical prints. The restoration technique has been published by Michel Hennin in 1856, in Paris France. The method of paper splitting technique is the splitting of one sheet of paper into two thinner sheets of the same dimension. Several artists have performed the paper slitting method in restoration of the old portraits including William A. Baldwin, restorer of the engraved portrait of Henri IV; Alfred Bonnardot, and the infamous German restorer, Max Schweidler.

With first cases noted towards the end of 2019 in China, COVID-19 infection was rapidly become a devastating pandemic. Even if most patients present with a mild to moderate form of the disease, the estimated prevalence of COVID-19-related severe acute respiratory failure (ARF) is 15-20% and 2-12% needed intubation and mechanical ventilation. In addition to mechanical ventilation some other techniques of respiratory support could be used in some forms of COVID-19 related ARF. This position paper of the Respiratory Support and Chronic Care Group of the French Society of Respiratory Diseases is intended to help respiratory clinicians involved in care of COVID-19 pandemic in the rational use of non-invasive techniques such as oxygen therapy, CPAP, non-invasive ventilation and high flow oxygen therapy in managing patients outside intensive care unit (ICU). The aims are: (1) to focus both on the place of each technique and in describing practical tips (types of devices and circuit assemblies) aimed to limit the risk of caregivers when using those techniques at high risk spreading of viral particles; (2) to propose a step-by-step strategy to manage ARF outside ICU., (Copyright © 2020 SPLF and Elsevier Masson SAS.

The philosopher David Hume is renowned in international monetary economics for his 1752 analysis of the specie-flow mechanism of international adjustment. He has been viewed in the literature as an abstract theorist, writing without direct practical experience of public policy or monetary affairs. This paper shows Hume in the unfamiliar role of a British diplomat negotiating the settlement of the outstanding paper money of New France after the British conquest of Canada.

Physical activity is important in heart failure to improve functional capacity, quality of life and prognosis, and is a class IA recommendation in the European Society of Cardiology guidelines (Ponikowski et al., 2016). The benefits of exercise training are widely recognized. Cardiac rehabilitation centres offer tailored exercise training to patients with heart failure, as part of specialized multidisciplinary care, alongside pharmacological treatment optimization and patient education. After cardiac rehabilitation, maintenance of regular physical activity long term is essential, as the benefits of exercise training vanish within a few weeks. Unfortunately, only 10% of patients benefit from a cardiac rehabilitation programme after hospitalization for acute heart failure, and the majority of patients do not pursue long-term physical activity. In this paper, two Working Groups of the French Society of Cardiology (the heart failure group [Groupe Insuffisance Cardiaque et Cardiomyopathies; GICC] and the cardiac rehabilitation group [Groupe Exercice Réadaptation Sport et Prévention; GERS-P]) discuss the obstacles to broader access to cardiac rehabilitation centres, and propose ways to improve the diffusion of cardiac rehabilitation programmes and encourage long-term adherence to physical activity., (Copyright © 2019 The Authors.

The objective of this article was to evaluate the evidence currently available about the clinical value of artificial intelligence (AI) in breast imaging. Nine experts from the disciplines involved in breast disease management - including physicists and radiologists - convened a meeting on June 3, 2019 to discuss the evidence for the use of this technology in plenary and focused sessions. Prior to the meeting, the group performed a literature review on predefined topics. This paper presents the consensus reached by this working group on recommendations for the future use of AI in breast screening and related research topics., (Copyright © 2019 Société française de radiologie.

Entered into force in 2011, the Protocol on Integrated Coastal Zone Management (ICZM) in the Mediterranean is a major innovation in that it is the first supra-State legal instrument aimed at coastal zone management. However, the nature and magnitude of change it is actually generating, or is likely to generate, in domestic coastal zones management systems, are highly uncertain. Investigating such prospects for change in contrasted contexts around the Mediterranean, and therefore providing a critical view of the Protocol as a game-changer, is the aim of this article. Results call for vigilance: the risk is real that the Protocol will not change much and that it will become a paper-protocol only. Ratifying it is – relatively – easy. Avoiding “ratifications of convenience” is more demanding. For various reasons the Protocol is likely to have mostly limited impacts on domestic coastal law development. It probably has more potential in terms of influencing changes in governance processes and increasing the social demand for ICZM. But this potential may only be translated into facts under stringent conditions on political will and good faith from Parties to adopt an ambitious understanding of the Protocol, and on appropriation by civil societies around the Mediterranean.

The present study is a scientometrics evaluation of refereed publications on bacterial mastitis in sheep; the objectives were the evaluation of the relevant papers and the presentation of quantitative characteristics regarding their scientific content and bibliometric details. The Web of Science platform was used with search terms: [mastitis OR *mammary infection*] AND [sheep OR ewe* OR ovine] for papers from 1970 tο 2019; only 'articles', 'reviews', 'proceedings papers', or 'data papers' were evaluated, whilst documents related solely to contagious agalactia, mammary aspects of lentiviral infections, or infections of the teats and the udder skin were excluded. Finally, 580 papers were considered in detail. The number of published papers increased from 8 during the 1970s to 273 during the 2010s. These papers originated from 43 countries (most from Greece or Spain, n = 87 from each) and 240 institutions (145 universities and 95 other establishments), of which 35 produced ≥ 5 papers each. Most papers present original studies (n = 539) with a few reviews (n = 41). The original papers refer to dairy (n = 428), meat (n = 113), or wool (n = 1) production systems and present field (n = 329), laboratory (n = 163), or experimental (n = 67) work; the papers report aetiology (n = 146), risk factors (n = 100), pathogenesis (n = 92), diagnosis (n = 88), effects (n = 66), treatment (n = 50), control (n = 36), or descriptive epidemiology (n = 32) of the disease. Papers related to dairy production present more field and fewer experimental work than papers related to meat production; also, in papers describing work performed in dairy sheep, studies about aetiology, risk factors, and diagnosis of the disease predominate, whilst in papers performed in meat sheep, studies about aetiology, pathogenesis, and effects/diagnosis are reported more often. The papers were published in 175 scientific journals (most in Small Ruminant Research, n = 90, or Journal of Dairy Science, n = 54). On average, the papers received 16.8 total citations and 1.6 yearly citations (h-index = 47). Most papers were published in Scimago classification Q1 (n = 240) or Q2 (n = 230) journals and received 23.4 or 15.4 total citations, respectively. Reviews received more citations than original papers; among the latter, papers with work referring to dairy production received more yearly citations than papers referring to meat production; no differences in citations were seen according to type of work or mastitis aspect covered. Most citations were received by papers from France. Papers published in Journal of Dairy Science or Small Ruminant Research received the most citations. In total, there were 1558 individual authors of the papers, with 24 authors having co-authored > 10 papers each (max: 73 papers); on average, there were 5.2 co-authors per paper (min–max: 1–25). Average number of co-authors progressively increased from 2.1 in the 1970s to 6.3 in the 2010s, with original papers having a higher number of co-authors than reviews: 5.3 and 3.7, respectively. Papers from France had highers number of co-authors (7.9). The findings of this first ever scientometrics study into ovine mastitis indicate that the disease has not been studied as other sheep diseases and that future studies in it should be directed to its control.

Rivers used for drinking water production might be subject to anthropogenic pollution discharge upstream of the intake point. This problem was investigated in the case of the Moselle River, used for water production in Nancy (350,000 inhabitants) and which might be impacted by industrial activities 60 km upstream. The arsenic flux of a pulp and paper mill discharging in the Moselle River at this location has been more specifically investigated. The main sources of arsenic in that mill seemed to be the recovered papers and the gravel pit water used as feed water. The arsenic input related to wood and bark was limited. The main arsenic outputs from the plant were the paper produced on site and the deinking sludge. The arsenic concentration in the effluent of the wastewater treatment plant (WWTP) was not correlated to the one in the gravel pit water, but may depend on the operating conditions of the WWTP or the changes in processes of the mill. The impact of this anthropogenic source of arsenic on the Moselle River was slightly larger in summer, when the flowrate was lower. Globally the impact of the paper mill on the Moselle River water quality was limited in terms of arsenic.

In France and Germany, significant networks of local initiatives have developed around energy issues. This article brings practitioners' viewpoints into discussion. It presents the way in which two of these networks – the CLER-network for the energy transition (France) and the 100% – Regions network (Germany) – each identifies itself, describes its action and build-up process in relation to government action, and conceives of justice issues in the field of climate energy policy. The analysis shows that these two networks share a lot, including political ends (localisation of energy production, empowerment of rural territories), but practice quite differently as intermediaries for local initiatives. This suggests overcoming the transition management vs grassroots divide present in the literature and paying more attention to hybrids. It also brings emphasis on a type of intermediary's work, which has not been covered by the academic literature, namely that of tinkering with multiple supports and embedding action in local-national-supranational networking in order to maintain continuity. In discussing justice dimensions, we emphasize that motives or ends of action are only reflectively related to ideas of justice: justice issues seem bound up with a politics of assembling, either as a marker of federative action (all fighting for justice) or as a potentially divisive issue.

The introduction of catheter ablation techniques has vastly improved the treatment of cardiac arrhythmias. However, as complex ablations are technically demanding and can cause various complications, they require a high level of expertise to maximize success rates and minimize complication rates. As French recommendations regarding the required technical competence and equipment are not yet available, this position paper has been compiled by the Working Group of Pacing and Electrophysiology of the French Society of Cardiology, detailing the required features of an interventional cardiac electrophysiological centre for complex ablation procedures: (1) sufficient institutional volume; (2) physician training, qualifications and experience; (3) paramedical staff training and attendance; and (4) institutional facilities and technical equipment. The importance of being able to diagnose, monitor and manage complications associated with complex ablations is highlighted. Supplemental hospital-based resources are also discussed, such as anaesthesia, surgical back-up, intensive care, haemodynamic assistance and imaging. Further, the ideal features of an interventional cardiac electrophysiology training centre are considered. Lastly, the need for quality evaluations and national registries for complex ablations is discussed., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

Aortic stenosis is a frequent disease in the elderly. Its prevalence is 0.4% with a sharp increase after the age of 65, and its outcome is very poor when the patient becomes symptomatic. The interventional procedure known as TAVI (trans-catheter aortic valve implantation), which was developed in France and carried out for the first time in Rouen by Prof. Alain Cribier and his team in 2002, has proven to be a valid alternative to surgical aortic valve replacement. At first, this technique was shown to be efficient in patients with contra-indications to surgical treatment or deemed to be at high surgical risk. Given the very promising outcomes achieved as a result of close heart team collaboration, appropriate patient selection, simplified procedures and reduced complication rates, transfemoral (TF) TAVI is now preferred in symptomatic intermediate risk patients>75 years old according to the latest ESC guidelines. In 2017, in France, TAVI is currently performed in 50 centers with on-site cardiac surgery. The 2016 TAVI outcomes recorded in the French national TAVI registry (France TAVI) are very encouraging and show that for 7133 patients treated (age 83.4±7 years, logistic Euroscore 14%), 87% of whom via the TF approach, cross-over to surgery was very low (0.5%) with a 3.0% in-hospital mortality rate. The substantial increase in TAVI indications and the improvement of its outcomes may in the near future call for a reconsideration of the number of high volume centers authorized to carry out this technique., (Copyright © 2018.

The occurrence of filamentous bacteria was investigated in 15 French pulp and paper activated sludge wastewater treatment plant (WWTP). Large filamentous populations were present in most of the plants. Identification carried out with conventional methods based on morphological features and staining techniques showed that the four main filamentous bacteria encountered in these industrial WWTP and responsible for bulking belong to the genera Thiothrix sp., Type 021 N, Haliscomenobacter hydrossis and Type 0092. During two years a specific survey was performed for three of these WWTP showing recurrent bulking phenomena. Data from WWTP performance, chemical data and filaments characterization were compared to correlate the presence of specific filaments with process operating conditions.

The Remaining Useful Life of a machine is very useful statistical information for the operator and manufacturer. It provides a very clear perspective to the user how long the machine can be operated and if any faults are detected how can they be prevented and ultimately increase the Remaining Useful Life. If the operators are aware of the forthcoming issues of the machine the downtime caused in the inspection, part delivery and eventually replacing parts is significantly reduced. The paper presents a study on the remaining useful life of machinery as it is an emerging technique, starting from the year 2010 to the current year of 2021. The bibliometric research is carried out using the Scopus database and software such as the VOS Viewer and GPS Visualizer. The study tells that the maximum publications are from articles and conference papers affiliated to remaining useful life, Chinese lead the publication followed by the United States and then France.

To translate EV-based therapeutic to clinic, the challenge is to demonstrate quality, safety, and efficacy, as required for any medicinal product. EV research translation into medicinal products is an exciting and challenging perspective. Recent papers, provide important guidance on regulatory aspects of pharmaceutical development, defining EVs for therapeutic applications and critical considerations for the development of potency tests. In addition, the ISEV Task Force on Regulatory Affairs and Clinical Use of EV-based Therapeutics as well as the Exosomes Committee from the ISCT are expected to contribute in an active way to the development of EV-based medicinal products by providing update on the scientific progress in EVs field, information to patients and expert resource network for regulatory bodies. The contribution of our work group "Extracellular Vesicle translatiOn to clinicaL perspectiVEs – EVOLVE France", created in 2020, can be positioned in complement to all these important initiatives. Based on complementary scientific, technical, and medical expertise, we provide EV-specific recommendations for manufacturing, quality control, analytics, non-clinical development, and clinical trials, according to current European legislation. We especially focus on early phase clinical trials concerning immediate needs in the field. The main contents of the investigational medicinal product dossier, marketing authorization applications, and critical guideline information are outlined for the transition from research to clinical development and ultimate market authorization.

The article analyzes the relation between slavery and the structures and practices of law with reference to a story of a woman named Rosalie who, in the late 18th century, was deported as a slave to the French colony of Saint-Domingue (modern day Haïti). Efforts made by Rosalie in regaining her liberty are highlighted. Role of law and judicial processes in upholding and challenging the structures of caste and white supremacy that emerged after the end of slavery is discussed.
