Authors: Wang Jie , Ye Jiang , Chen Sixuan , Zhang Qinyong
Published: April 2024

The crystal phase, alongside the composition, morphology, architecture, facet, size, and dimensionality, has been recognized as a critical factor influencing the properties of noble metal nanomaterials in various applications. In particular, unconventional crystal phases can potentially enable fascinating properties in noble metal nanomaterials. Recent years have witnessed notable advances in the phase engineering of nanomaterials (PEN). Within the accessible strategies for phase engineering, the effect of strain cannot be ignored because strain can act not only as the driving force of phase transition but also as the origin of the diverse physicochemical properties of the unconventional crystal phase. In this review, we highlight the development of unconventional crystal-phase noble metal nanomaterials within strain engineering. We begin with a short introduction of the unconventional crystal phase and strain effect in noble metal nanomaterials. Next, the correlations of the structure and performance of strain-engineered unconventional crystal-phase noble metal nanomaterials in electrocatalysis are highlighted, as well as the phase transitions of noble metal nanomaterials induced by the strain effect. Lastly, the challenges and opportunities within this rapidly developing field (i.e., the strain engineering of unconventional crystal-phase noble metal nanocatalysts) are discussed.

Published: April 2024

Taraxacum kok-saghyz (TKS), a rubber-producing plant with excellent potential, emerges as a viable substitute for rubber tree (Hevea brasiliensis). While natural rubber is a desirable material, conventional techniques for assessing rubber content have faced challenges in meeting practical production requirements. To address this issue, we have developed a pyrolysis–mass spectrometry (PY-MS) instrument for the quantitative evaluation of natural rubber (NR) content in rubber-producing plants. The derived standard curve equation, established for the detection of TKS dry weight through external standard calibration, demonstrates a correlation coefficient (R2) surpassing 0.99. The method exhibits commendable recovery rates (93.27–107.83%), relative standard deviations (RSD ≤ 3.93%), and a swift analysis time of merely 10 min per sample, thereby enabling accurate and efficient quantification of NR dry weight. Additionally, the PY-MS system we designed can be modified for vehicular use, enabling on-site, in situ analysis, and it provides substantial support for TKS breeding and propagation efforts. This approach possesses significant potential for extensive utilization in the assessment of rubber content in rubber-producing plants other than TKS. The integration of pyrolysis–mass spectrometry for the identification of polymers with high molecular weight offers a valuable pathway for the examination of diverse polymers.

Published: April 2024

The current exceeding of six out of nine planetary boundaries requires a significant transition of human societies towards absolute sustainability. Industrial manufacturing systems were and still are an important motor for socio-economic development but at the cost of a significant negative impact on the biosphere. Current concepts in absolute sustainability and sustainable manufacturing provide solutions for sustainability transitions in industry, but various methodological, technical and procedural challenges arise during their adaptation in industrial practice. The development and operationalization of a “zero impact factory” strategy by Volkswagen Group has identified various implementational challenges, which are discussed in this article. First, an overview of motivations for “zero impact” transformations in industry are pointed out. Second, relevant aspects for the strategic management of sustainability transitions in manufacturing companies are highlighted based on a literature analysis. Third, the strategy development process is explained based on a systematic structure, which includes design-thinking principles for sustainability transitions of large technical systems such as factories in global manufacturing systems. Fourth, the developed strategy content is presented, including (1) the strategy vision, (2) the defined quantified “zero impact” goals, (3) a system model and a prototype of a zero impact factory, (4) the developed “Impact Points” and the “Site Checklist” methods (for evaluating the environmental transformation of a factory) and (5) the definition of processes for strategic management during strategy operationalization. Finally, various organizational challenges and opportunities are pointed out, which are considered novel insights from industrial practice and relevant for the science-based strategic management within automotive companies and other global industrial manufacturing organizations, as well for advancing sustainability concepts in applied industrial science.

Due to their significant environmental impact, there has been a gradual restriction of the production and utilization of legacy per- and polyfluoroalkyl substances (PFAS), leading to continuous development and adoption of novel alternatives. To effectively identify the potential environmental risks from crop consumption, the levels of 25 PFAS, including fourteen perfluoroalkyl acids (PFAAs), two precursor substances and nine novel alternatives, in agricultural soils and edible parts of various crops around a fluoride industrial park (FIP) in Changshu city, China, were measured. The concentration of ΣPFAS in the edible parts of all crops ranged from 11.64 to 299.5 ng/g, with perfluorobutanoic acid (PFBA) being the dominant compound, accounting for an average of 71% of ΣPFAS. The precursor substance, N-methylperfluoro-octanesulfonamidoacetic acid (N-MeFOSAA), was detected in all crop samples. Different types of crops showed distinguishing accumulation profiles for the PFAS. Solanaceae and leafy vegetables showed higher levels of PFAS contamination, with the highest ΣPFAS concentrations reaching 190.91 and 175.29 ng/g, respectively. The highest ΣAlternative was detected in leafy vegetables at 15.21 ng/g. The levels of human exposure to PFAS through crop consumption for various aged groups were also evaluated. The maximum exposure to PFOA for urban toddlers reached 109.8% of the standard value set by the European Food Safety Authority (EFSA). In addition, short-chained PFAAs and novel alternatives may pose potential risks to human health via crop consumption.

Nous montrons comment une méthodologie basée sur un principe d’optimisation logique des unités de correspondances lettres-sons dans un large corpus (un lexique déformés canoniques du français, Le 60 000, et les références phonétiques du Petit Robert,), permet de faire émerger une classification linguistique des phénomènes de phonétisation.

Une grammaire substrat primitive, constituant le noyau de la phonétisation, a été étendue en adoptant une méthodologie de bootstrapping. Cette description est donnée en langage formel TOPH, qui permet d’intégrer règles et lexiques au sein d’une même logique de phonétisation. Une unité minimale de correspondance, le graphone, permet de reconstituer les variations du graphème. Des sous-systèmes, décrivant des sous-lexiques, sont clairement isolés comme des transferts phonologiques de langues-source vers le français.
Variants/invariants linguistiques dans les « enfantines » du folklore des écoliers
Authors: Chauvin Carole
Published: April 2024

L’intérêt des spécialistes pour le folklore enfantin a débuté vers les années 1930-1940. Cet intérêt relativement tardif est sans doute lié à ce que Brian Sutton-Smith (Sutton-Smith, 1970 : 1-8) a appelé « the triviality barrier ». Étudier les coutumes apparemment simples et triviales des enfants semblait relever d’une activité elle-même triviale. Pourtant, le folklore enfantin est particulièrement riche quant aux traditions langagières, musicales et gestuelles qui perdurent, se transmettent et évoluent.

Dans le cadre de nos recherches, nous nous sommes intéressée à l’étude du folklore des écoliers (constituant une partie du folklore enfantin), le milieu scolaire/récréatif nous apparaissant comme l’un des plus favorables à l’observation et à l’analyse des pratiques ludiques enfantines.

Nous décrirons ici les phénomènes de variabilité et/ou de stabilité linguistique concernant le lexique et la structure formelle de l’énoncé.

Neural Correlates of Motor/Tactile Imagery and Tactile Sensation in a BCI paradigm: A High-Density EEG Source Imaging Study
Authors: Wen Huan , Zhong Yucun , Yao Lin , Wang Yueming
Published: April 2024

Complementary to brain–computer interface (BCI) based on motor imagery (MI) task, sensory imagery (SI) task provides a way for BCI construction using brain activity from somatosensory cortex. The underlying neurophysiological correlation between SI and MI was unclear and difficult to measure through behavior recording. In this study, we investigated the underlying neurodynamic of motor/tactile imagery and tactile sensation tasks through a high-density electroencephalogram (EEG) recording, and EEG source imaging was used to systematically explore the cortical activation differences and correlations between the tasks. In the experiment, participants were instructed to perform the left and right hand tasks in MI paradigm, sensory stimulation (SS) paradigm and SI paradigm. The statistical results demonstrated that the imagined MI and SI tasks differed from each other within ipsilateral sensorimotor scouts, frontal and right temporal areas in α bands, whereas real SS and imagined SI showed a similar activation pattern. The similarity between SS and SI may provide a way to train the BCI system, while the difference between MI and SI may provide a way to integrate the discriminative information between them to enhance BCI performance. The combination of the tasks and its underlying neurodynamic would provide a new approach for BCI designation for a wider application. BCI studies concentrate on the hybrid decoding method combining MI or SI with SS, but the underlining neurophysiological correlates between them were unclear. MI and SI differed from each other within the ipsilateral sensorimotor cortex in alpha bands. This is a first study to investigate the neurophysiological relationship between MI and SI through an EEG source imaging approach from high-density EEG recording.

Authors: Zhang Jiawei , Bai Chengchao , Yue C. Patrick , Guo Jifeng
Published: April 2024

Space manipulators play an important role in the on-orbit services and planetary surface operation. In the extreme environment of space, space manipulators are susceptible to a variety of unknown disturbances. How to have a resilient guarantee in failure or disturbance is the core capability of its future development. Compared with traditional motion planning, learning-based motion planning has gradually become a hot spot in current research. However, no matter what kind of research ideas, the single robotic manipulator is studied as an independent agent, making it unable to provide sufficient flexibility under conditions such as external force disturbance, observation noise, and mechanical failure. Therefore, this paper puts forward the idea of “discretization of the traditional single manipulator”. Different discretization forms are given through the analysis of the multi-degree-of-freedom single-manipulator joint relationship, and a single-manipulator representation composed of multiple new subagents is obtained. Simultaneously, to verify the ability of the new multiagent representation to deal with interference, we adopted a centralized multiagent reinforcement learning framework. The influence of the number of agents and communication distances on learning-based planning results is analyzed in detail. In addition, by imposing joint locking failures on the manipulator and introducing observation and action interference, it is verified that the “multiagent robotic manipulator” obtained after discretization has stronger antidisturbance resilient capability than the traditional single manipulator.

Challenges and Prospects for Women Entrepreneurs in Tunisia
Authors: Mtibaa Nizar , Boudabbous Sami
Published: April 2024

Women who do not have a salaried employment contract have the opportunity to work on a self-employed basis to generate an income. Under self-employed status, these women take on, alone or perhaps in partnership, all the financial, administrative and social risks involved in developing their activities.
In this approach, we will focus on the reality of these women who are self-employed. The aim of this research is to understand the entrepreneurial process of women, by distinguishing three different realities: women entrepreneurs, women in the professions and women involved in cooperatives. This shows how complex and diverse the notion of female entrepreneurship is. Through this research, we defend the idea that we need to approach the situation of these women entrepreneurs from a systemic angle, since their daily lives are the result of an interaction between their professional lives and their family lives. Their choices are guided by their positions in society and by the infrastructure that society makes available to them.
Finally, understanding these women entrepreneurs, and what motivates and guides their choice, cannot be done without a diversion through the reality of the labour market, and without cross-referencing other variables such as level of qualification, age or origin. Thus, we will mobilize their individual and family variables, the specific features linked to the characteristics of their companies and the sector of activity, and the socio-economic, cultural, political and legal characteristics of Tunisia.

Сенсоневральная тугоухость различной степени выраженности и эпилепсия могут сосуществовать при различных клинических синдромах, в том числе в рамках орфанных генетических заболеваний. В статье представлен клинический случай электроакустической коррекции слуха у пациента с синдромом эпилепсии, потери слуха и умственной отсталости, ассоциированным с мутациями в гене SPATA5. Электроакустическая стимуляция у пациентов с эпилепсией и снижением слуха теоретически сопряжена с риском возникновения эпилептических эпизодов, поскольку у этих пациентов имеются структурные или метаболические нарушения ЦНС, связанные с повышенным риском развития судорог. Слухоречевая реабилитация пациента проводилась посредством бинаурального слухопротезирования вначале и далее, в связи с неэффективностью слуховых аппаратов, проведения кохлеарной имплантации и последующей бимодальной стимуляции. В процессе динамического наблюдения за данным пациентом при использовании слуховых аппаратов, речевого процессора кохлеарного импланта, а также при дальнейшей бимодальной стимуляции увеличения эпиактивности на ЭЭГ не отмечалось. Электроакустическая коррекция слуха позволила расширить слуховые возможности данного пациента и улучшить качество его жизни.

Sensorineural hearing loss, of varying severity, and epilepsy can coexist in various clinical syndromes, including orphan genetic diseases. The article presents a clinical case of electroacoustic hearing correction in a patient with the syndrome of epilepsy, hearing loss and mental retardation associated with mutations in the SPATA5 gene. Electroacoustic stimulation in patients with epilepsy and hearing loss is theoretically associated with the risk of epileptic episodes, since these patients have structural or metabolic disorders of the CNS associated with an increased risk of seizures. Hearing-speech rehabilitation of the patient was carried out by means of binaural hearing aids at the beginning and later, due to the ineffectiveness of hearing aids, cochlear implantation and subsequent bimodal stimulation. In the process of dynamic monitoring of this patient with the use of hearing aids, the speech processor of the cochlear implant, as well as with further bimodal stimulation, no increase in EEG epiactivity was noted. Electroacoustic hearing correction allowed to expand the auditory capabilities of this patient and improve his quality of life.

Study of the adsorption-desorption of Cr (III) on green silica obtained from sodium silicate
Authors: Salazar-Hernández Carmen
Published: April 2024

Mesoporous silica (MS) is nowadays one of the most
widely used materials for the removal of contaminants in
water; however, its main disadvantage is its production
cost, since it is obtained by the sol-gel process using
tetraethyl orthosilicate (TEOS) as silica former, which is
not an economical reagent. In this article, we propose the
synthesis route of SM from industrial sodium silicate;
Na2SiO3 by passing it through an ion exchange column
(DOWEX-50WX8-100) to obtain silicic acid (Si(OH)4).
The acid fraction is collected from the ion exchange
column at pH 1–3 and allowed to age for 24 h. The SM
silicate is formed from the gelation of the aged silicic acid
and was characterized by infrared spectroscopy. The
porosity was determined by N2 desorption adsorption
isotherms and scanning electron microscopy. The Cr(3+)
removal capacity was evaluated by the effect of the initial
Cr(3+) concentration. Obtaining that the maximum
removal capacity was 108.7 mg/g for a Cr3+ solution of
2794 ppm

Design of an adjustable prop made of Polymeric material
Authors: Pérez-Pérez Arnulfo
Published: April 2024

In this work, an adjustable prop made of polymeric
material was designed. To do this, standards that refer
to this element were consulted and which specify that
the load that the prop must support is 6000 N including
live loads and dead loads. Consequently, the selection
of the appropriate polymer for this application was
carried out through a comparison of the mechanical
properties of these materials, with acetal proving to be
better. With this information, a buckling analysis was
carried out using the analytical method considering an
adjustable prop length of 3 m. In addition, supported by
the Solidworks® software, a simulation of the critical
load and contact stress was also carried out, resulting in
the fixed part of the adjustable prop being a tube with
an internal diameter of 80 mm and an external diameter
of 95 mm. The adjustable part must be solid with a
diameter of 80 mm

Introduction: Vitamin D is a fat-soluble vitamin used by the body for bone development and maintenance through the increased absorption of calcium, magnesium, and phosphate. Vitamin D deficiency, or insufficiency, has been identified as a global problem that affects at least one billion people worldwide. The presence of muscle weakness, falls, and fractures associated with vitamin D deficiency is frequent in the elderly; however, its impact on young people is little known. 
Clinical Case: We present the case of a 34-year-old male with no sun exposure and a history of consuming alcoholic beverages, presenting with progressive muscle weakness and a non-traumatic bilateral humeral fracture associated with vitamin D deficiency. We also describe the diagnostic-therapeutic approach as well as review the literature and its current importance. 
Conclusions: Vitamin D deficiency is common and often unrecognized, yet it can play an important role in exacerbating underlying pathologies, especially in vulnerable populations. Proximal humerus fractures are common among elderly patients, but not in young people, and less in the absence of trauma. In low-energy fractures without obvious traumatic mechanisms, greater prevalence has been observed in patients with low vitamin levels.
Plantas para tus riñones: una revisión narrativa sobre la dieta basada en plantas y la enfermedad renal crónica

La enfermedad renal crónica (ERC) es una afección prevalente que afecta a millones de personas en todo el mundo. Los tratamientos convencionales a menudo no proporcionan recuperación renal, lo que lleva a un creciente interés en intervenciones dietéticas alternativas. Las dietas basadas en plantas han ganado atención debido a su potencial para aliviar las complicaciones relacionadas con esta patología y promover la salud en general. Este artículo examina la literatura sobre dietas basadas en plantas en el manejo de la ERC en tratamiento conservador, y destaca sus beneficios potenciales en el control de la presión arterial, la reducción de la inflamación, la mitigación del estrés oxidativo y la mejora del perfil lipídico. También discute los desafíos y las consideraciones asociados con la adopción de este tipo de regímenes alimentarios, incluidas las posibles deficiencias de nutrientes y los ajustes de medicamentos. El artículo enfatiza la importancia de los enfoques dietéticos individualizados considerando factores como la etapa de la ERC, las comorbilidades y los requisitos nutricionales. También destaca el papel de los profesionales nutricionistas en la educación y orientación de estos pacientes hacia patrones dietéticos apropiados basados en plantas. Se necesita investigación adicional para dilucidar la composición óptima y la viabilidad de las dietas basadas en plantas en el tratamiento de individuos que padecen ERC en manejo conservador.
Estudio epidemiológico de la respuesta inmune en pacientes con enfermedad de Chagas Mazza
Authors:   , Delaplace Laura Andrea
Published: April 2024

La enfermedad de Chagas-Mazza, es una infección ocasionada por el protozoo Trypanosoma cruzi. Es endémica en América Latina y afecta a unos 18 millones de personas, siendo la causa de unas 50. 000 muertes cada año. En nuestro país se calculan actualmente en 1.700.000 los infectados, con 6.900.000 habitantes en riesgo de contraer la infección. La aparición desautonomía chagásica es una de las manifestaciones más tempranas de la enfermedad. Esta progresa en virtud de una respuesta inflamatoria y autoinmune del organismo a la presencia del parásito con aumento progresivo de desautonomía que a su vez provoca diversas respuestas compensatorias en el organismo y particularmente en el corazón conduciendo a la aparición de trastornos eléctricos (arritmias) y remodelamiento ventricular o miocardiopatía chagásica. La enfermedad sigue este curso en aproximadamente entre el 30 y el 40% de las personas infectadas. El tratamiento medicamentoso de la enfermedad se basa en la administración de antiparasitarios y asegura la cura con negativización de la serología en individuos hasta los 15 años. En adultos crónicos no se observa negativización de la serología y por lo tanto no existe un indicador aceptado de cura. El objetivo del trabajo es evaluar la presencia de anticuerpos antimuscarínicos en sangre periférica, en pacientes diagnosticados con Chagas en todos los estadios de la enfermedad, en función de la edad, el sexo y la etapa evolutiva de la enfermedad. El estudio realizado es de naturaleza transversal, observacional, descriptivo y prospectivo. Los datos fueron colectados en campañas de detección y estratificación de Chagas organizadas por diversas Instituciones. La población fue escogida al azar de un total de 424 personas con sospecha alta de infección temprana. Evaluamos la presencia de anticuerpos anti-M2 como posible marcador de progresión de la enfermedad. Encontramos diferencias significativas entre sexos. Mientras que, en el sexo masculino, la positividad indica un progreso más rápido hacia formas más graves de la enfermedad no ocurre lo mismo entre las mujeres. Esto podría indicar que las mujeres progresan más lentamente en virtud de efectos protectores a nivel cardíaco; o bien que las mujeres progresan desarrollando sintomatología no considerada hasta ahora para estratificar el progreso de la enfermedad. Estas diferencias pueden explicar las dificultades para establecer este indicador como marcador de progreso de la enfermedad. Una evolución de la enfermedad diferenciada por sexo nos lleva a pensar en la necesidad de criterios de clasificación y medidas de protección también diferenciadas por sexo.
La transe afro-brésilienne, un travail sur le corps pour communiquer avec les dieux
Authors: Guméry Claude
Published: April 2024

Dans les religions afro-brésiliennes, le contact avec les divinités s’établit par le biais de la transe. L’article, qui se fonde sur les travaux de Roger Bastide et Pierre Verger, identifie qui sont les personnes aptes à entrer en transe pour communiquer avec les dieux. On étudie ensuite comment elles préparent leur corps à recevoir leur dieu, et comment elles l’entretiennent de façon à ce que la transe puisse se répéter au cours de la vie religieuse d’une communauté. Ces personnes jouissent d’un statut social particulier au sein de la communauté, car d’une part elles ont commerce avec les dieux, et d’autre part ce commerce leur donne pouvoir à orienter la vie de la communauté. Il y a donc interaction entre le corps de l’individu et le corps social qui l’entoure et qui adhère à la croyance. L’anthropologie moderne a redonné un statut à la fois aux « possédés » et aux cultes afro-brésiliens, alors que les premiers scientifiques qui les ont étudiés ne voyaient en la transe que la manifestation d’une folie.
Analyse d’une chanson de tradition orale : articulation entre poétique et imaginaire
Authors: Charnier Brigitte
Published: April 2024

Analyser une chanson de tradition orale française dans le cadre d’une thèse de littérature et dans une perspective mythique nécessite une démarche atypique d’autant que cette complainte se décline en plus d’une vingtaine de versions. Ce sujet étant peu traité, il a fallu tout d’abord définir l’objet « chanson de tradition orale », ce qui a eu comme mérite de mettre en relief les différents acteurs ayant présidé à la création de cette notion : folkloristes et médiévistes ont montré les pistes à suivre et jalonné les investigations menées dans le cadre de cette thèse. Grâce à leurs analyses, il a été possible de rendre visibles des critères poétiques spécifiques à la tradition orale et de constituer un corpus représentatif de l’oralité. Il est rapidement apparu qu’une analyse formelle était indissociable d’une quête du sens, de même que croiser les disciplines et pratiquer l’art du comparatisme afin de débusquer à travers contes, légendes et tradition orale un éventuel scénario mythique originel. Face à l’originalité de la complainte, celui‑ci est vite apparu comme réducteur et ce n’est qu’à travers l’étymologie, l’hagiographie et l’onomastique qu’il a été possible d’affiner les analyses et de proposer une interprétation herméneutique.
Carte d’identité linguistique des odeurs
Authors: Kleiber Georges
Published: April 2024

Nous ne nous intéresserons ici qu’au problème bien connu de l’identification des odeurs. Nous exposerons d’abord, dans une première partie, quelle est la situation dénominative à laquelle donnent lieu les noms d’odeurs, en examinant le statut des noms généralement reconnus comme tels. Nous montrerons qu’il ne s’agit pas de véritables odoronymes, mais qu’ils se divisent en deux catégories, les noms « généraux », qui fonctionnent au même niveau qu’odeur, et les faux noms d’odeurs qui sont uniquement des spécifieurs d’odeurs. Notre seconde partie analysera la construction odeur de N à laquelle on recourt habituellement pour identifier les odeurs particulières. Nous essaierons de dégager, à partir de ses caractéristiques, les raisons de son succès.
L’Analyse de scènes audio‑visuelles : un paradigme venu de la Gestalt, en plein essor pour l’étude de la multimodalité du langage
Authors: Troille Émilie
Published: April 2024

Dans cet article nous déclinerons langage et images, en parole et visage, en mouvements anticipés, imaginés et en illusions du son par l’image. Ce sera l’occasion pour nous de revisiter la notion de Gestalt dont on a pu dire, depuis le structuralisme, qu’elle était définitivement dépassée. En ce qui concerne Les Structures anthropologiques de l’imaginaire de Gilbert Durand, on rappellera que la Gestalt n’est — même pas implicitement — une approche exclusivement statique de la cognition. Bien au contraire, nous montrerons que c’est à partir des mouvements qu’émergent les formes et que se stabilisent en mémoire la morphologie des gestes audibles et visibles de la bouche, saisis au vol dans le décours d’un flux de quelque quatre à six syllabes à la seconde, via la perception des coordinations motrices qu’il est nécessaire de maîtriser pour l’expression courante du langage entre humains. Nous appliquerons ici, pour les flux perceptifs du langage, l’Analyse de scènes, héritière de la Gestalt, y compris pour l’expression gestuelle du visage et de la main chez les sourds qui pratiquent la Langue française Parlée Complétée (LPC), adaptée du Cued Speech du Dr Richard Cornett (1967).
