Published: May 2022

With increased interest in renewable energy, the power capacity of wind turbines is constantly increasing, which leads to increased rotor sizes. With ever larger rotor diameters, the complex and non-linear fluid-structure interaction (FSI) effects on wind turbine aerodynamic performances become significant, which can be fully studied using hi-fidelity 2-way FSI simulation. In this study, a two-way FSI model is developed and implemented in Openfoam to investigate the FSI effects on the NREL Phase VI wind turbine. The fully structured multiblock (MB) mesh method is used for the fluid and solid domains to achieve good accuracy. A coupling method based on the ALE is developed to ensure rotation and deformation can happen simultaneously and smoothly. The simulation results show that hi-fidelity CFD (Computational Fluid Dynamics) and CSD (Computational Structural Dynamics) -based 2-way FSI simulation provides high accurate results for wind turbine simulation and multi-disciplinary design optimization (MDO).

Value-directed strategic processing involves attending to higher-value information while inhibiting lower-value information. This preferential processing is relatively preserved in cognitively normal older adults but is impaired in individuals with dementia. No studies have investigated whether value-directed strategic processing is disrupted in earlier stages of cognitive decline, namely, mild cognitive impairment (MCI). The current study examined behavioral and EEG differences in value-directed strategic processing between 18 individuals with MCI and 18 cognitively normal older controls using a value-directed list learning task. Behaviorally, individuals with MCI recalled fewer total and high-value words compared to controls, but no group differences were observed in low-value word recall. Neurally, individuals with MCI had reduced theta synchronization relative to controls between 100 and 200 ms post-stimulus. Greater alpha desynchronization was observed for high- versus low-value words between 300 and 400 ms in controls but not in the MCI group. The groups showed some processing similarities, with greater theta synchronization for low-value words between 700 and 800 ms and greater alpha desynchronization for high-value words between 500 and 1100 ms. Overall, value-directed strategic processing was compromised in individuals with MCI on both behavioral and neural measures relative to controls. These findings add to the growing body of literature on differences between typical cognitive aging and MCI.

Wild edible plants have been used since antiquity as folk medicine and as preservatives in foods. This study aimed to determine the antioxidant activities, phenolic compounds, and hormone contents of 12 species of edible wild plants belonging to 9 families, which are consumed as vegetables by the local people at Ergan Mountain in Erzincan in Turkey. Polygonum cognatum and Malva neglecta were determined to have more antioxidant enzyme activity, more phenolic compounds, and higher hormone content than the other species. The highest catalase (CAT), peroxidase (POD), glutathione reductase (GR), glutathione-s-transferase (GST) values for P. cognatum were determined as 45.12, 94.83, 36.76, and 1218.35 EU g−1, respectively. The highest superoxide dismutase (SOD) and ascorbate peroxidase (AxPOD) content for M. neglecta were determined as 97.53 EU g−1 and 81.93 EU g−1, respectively. P. cognatum is the species in which the highest levels of the hormones indolacetic acid (IAA), gibberellic acid (GA), salicylic acid (SA), cytokinin, zeatin and jasmonic acid were detected. The highest levels of caftaric acid (CA), catechin (CAE), ferulic acid (FA), malvidin-3-o-glucoside (MG), myricetin (MYR), rutin (RT), trans-coumaric acid (TPCA), tyrosol (TY), and vanilic acid (VA) compounds were found in M. neglecta. It was determined that Falcaria vulgaris species had the highest levels of ferulic acid (FA) and quercetin (QUE) phenolics. The results show that edible wild vegetables consumed and studied by the people of the region are an important source of natural antioxidants. The possibilities of using these wild plants as functional foods should be investigated.

In recent years, the importance of professionalism of convention workers has been rapidly emerging. Therefore, the purpose of this study is to establish a strategy for strengthening the professionalism of convention workers. For this, the study investigates if there are any differences in job satisfaction and job performance based on the segmented groups of professionalism perception of convention workers. The results of factor analysis showed six underlying dimensions of professionalism perception of convention workers. Cluster analysis showed that there were different segmented groups of professionalism perception: high level (cluster 1), low level (cluster 2), moderate level (cluster 3). Lastly, MANOVA showed that there were differences in job satisfaction and job performance among the segmented groups. More theoretical and practical implications are discussed in the conclusion.
Use of Online Newborn Screening Educational Resources for the Education of Expectant Parents: An Improvement in Equity
Authors: Thompson Kristen , Atkinson Shelby , Kleyn Mary
Published: May 2022

Educating parents about the newborn screening (NBS) process is critical in ensuring that families are aware of their child’s NBS, which could contribute to better outcomes for the baby and experiences for the family. Successful education efforts result in expecting parents understanding the importance of NBS, feeling comfortable with the NBS process, and being aware of their choices after NBS is complete. Educating parents prenatally is challenging for many NBS programs for a variety of reasons. The COVID-19 pandemic added additional barriers to NBS programs’ ability to educate parents prenatally about NBS. By initiating a department-wide partnership among other programs with a similar target audience, Michigan’s NBS Program was able to host a virtual baby fair. Since the inaugural event, Michigan’s NBS Program has hosted seven virtual fairs with 15 participating programs. A total of 692 participants registered for the baby fair and received a resource packet, over 157 participants joined one of the live presentations, and 211 have viewed the YouTube videos of recorded fairs. Virtual baby fairs are a cost-effective and convenient approach to education that could be implemented in any NBS program to educate parents prenatally about NBS.

Published: May 2022

Extranodal natural killer/T(NK/T)-cell lymphoma (ENKTL) is a rare subtype of non-Hodgkin lymphoma that typically presents with an isolated nasal mass, but a sizeable minority present with advanced stage disease and have a significantly poorer prognosis. Those with limited disease are standardly treated with chemotherapy and radiation while those with advanced stage disease are treated with L-asparaginase containing chemotherapy regimens. The addition of modern radiation therapy techniques and the incorporation of L-asparaginase into chemotherapy regimens have significantly improved outcomes in this disease, but relapses and death from relapsed disease remain frequent. Given the high rate of relapse, several novel therapies have been evaluated for the treatment of this disease. In this review, we explore the current standard of care for ENKTL as well as novel therapies that have been evaluated for its treatment and the biologic understanding behind these therapies.

Published: May 2022

To compare differences in postural balance, pain and depression in patients with chronic and acute low back pain, twenty patients with chronic and twenty patients with acute low back pain from the Edward Francis Small Hospital (Banjul, Gambia), as well as 20 age-matched healthy controls participated in the study. A modified Romberg test was used to assess postural balance during one minute with closed eyes. Body sway in the anteroposterior and mediolateral axes was video-recorded during test performance and further analyzed with an open source software for movement analyses (CvMob). Pain sensitivity was assessed by means of pressure pain thresholds and depression by a self-report questionnaire (PHQ-9). As results, patients with chronic low back pain displayed higher body sway in the anteroposterior and mediolateral axes, as well as faster body sway than patients with acute low back pain and healthy controls. Nevertheless, group differences disappeared when depression was introduced as a covariate, indicating a major role of depression in postural balance deficits of patients with pain disorders. As conclusions, the assessment of postural balance and depression should be implemented in the clinical routine for the design of tailored interventions in pain conditions.

Published: May 2022

(1) Background: The stethoscope is one of the main accessory tools in the diagnosis of temporomandibular joint disorders (TMD). However, the clinical auscultation of the masticatory system still lacks computer-aided support, which would decrease the time needed for each diagnosis. This can be achieved with digital signal processing and classification algorithms. The segmentation of acoustic signals is usually the first step in many sound processing methodologies. We postulate that it is possible to implement the automatic segmentation of the acoustic signals of the temporomandibular joint (TMJ), which can contribute to the development of advanced TMD classification algorithms. (2) Methods: In this paper, we compare two different methods for the segmentation of TMJ sounds which are used in diagnosis of the masticatory system. The first method is based solely on digital signal processing (DSP) and includes filtering and envelope calculation. The second method takes advantage of a deep learning approach established on a U-Net neural network, combined with long short-term memory (LSTM) architecture. (3) Results: Both developed methods were validated against our own TMJ sound database created from the signals recorded with an electronic stethoscope during a clinical diagnostic trail of TMJ. The Dice score of the DSP method was 0.86 and the sensitivity was 0.91; for the deep learning approach, Dice score was 0.85 and there was a sensitivity of 0.98. (4) Conclusions: The presented results indicate that with the use of signal processing and deep learning, it is possible to automatically segment the TMJ sounds into sections of diagnostic value. Such methods can provide representative data for the development of TMD classification algorithms.

Published: May 2022

Background: After a traumatic brain injury (TBI), the cell environment is dramatically changed, which has various influences on grafted neural stem cells (NSCs). At present, these influences on NSCs have not been fully elucidated, which hinders the finding of an optimal timepoint for NSC transplantation. Methods: Brain extracts of TBI mice were used in vitro to simulate the different phase TBI influences on the differentiation of human NSCs. Protein profiles of brain extracts were analyzed. Neuronal differentiation and the activation of autophagy and the WNT/CTNNB pathway were detected after brain extract treatment. Results: Under subacute TBI brain extract conditions, the neuronal differentiation of hNSCs was significantly higher than that under acute brain extract conditions. The autophagy flux and WNT/CTNNB pathway were activated more highly within the subacute brain extract than in the acute brain extract. Autophagy activation by rapamycin could rescue the neuronal differentiation of hNSCs within acute TBI brain extract. Conclusions: The subacute phase around 7 days after TBI in mice could be a candidate timepoint to encourage more neuronal differentiation after transplantation. The autophagy flux played a critical role in regulating neuronal differentiation of hNSCs and could serve as a potential target to improve the efficacy of transplantation in the early phase.

Published: May 2022

Magnetic resonance imaging (MRI) can be used to measure cardiac output (CO) non-invasively, which is a paramount parameter in pulmonary hypertension (PH) patients. We retrospectively compared stroke volume (SV) obtained with MRI (SVMRI) in six localisations against SV measured with thermodilution (TD) (SVTD) and against each other in 24 patients evaluated in our PH centre using Bland and Altman (BA) agreement analyses, linear correlation, and intraclass correlation (ICC). None of the six tested localisations for SVMRI reached the predetermined criteria for interchangeability with SVTD, with two standard deviations (2SD) of bias between 24.1 mL/beat and 31.1 mL/beat. The SVMRI methods yielded better agreement when compared against each other than the comparison between SVMRI and SVTD, with the best 2SD of bias being 13.8 mL/beat. The inter-observer and intra-observer ICCs for COMRI were excellent (inter-observer ICC between 0.889 and 0.983 and intra-observer ICC between 0.991 and 0.999). We could not confirm the interchangeability of SVMRI with SVTD based on the predetermined interchangeability criteria. The lack of agreement between MRI and TD might be explained because TD is less precise than previously thought. We evaluated a new method to estimate CO through the pulmonary circulation (COp) in PH patients that may be more precise than the previously tested methods.

Published: May 2022

Huntington’s disease (HD) is a rare, hereditary, and progressive neurodegenerative disease, characterized by involuntary choreatic movements with cognitive and behavioral disturbances. In order to mitigate impairments in motor function, physical exercise was integrated in HD rehabilitative interventions, showing to be a powerful tool to ameliorate the quality of life of HD-affected patients. This review aims to describe the effects of physical exercise on HD-related skeletal muscle disorders in both murine and human models. We performed a literature search using PubMed, Scopus, and Web of Science databases on the role of physical activity in mouse models of HD and human patients. Fifteen publications fulfilled the criteria and were included in the review. Studies performed on mouse models showed a controversial role played by exercise, whereas in HD-affected patients, physical activity appeared to have positive effects on gait, motor function, UHDMRS scale, cognitive function, quality of life, postural stability, total body mass, fatty acid oxidative capacity, and VO2 max. Physical activity seems to be feasible, safe, and effective for HD patients. However, further studies with longer follow-up and larger cohorts of patients will be needed to draw firm conclusions on the positive effects of exercise for HD patients.

Published: May 2022

In order to improve the trajectory tracking accuracy of an Underwater Vehicle Manipulator System (UVMS) under uncertain disturbance conditions of ocean current, a Model-free Adaptive Control (MFAC) method was used. Combined with Radial Basis Function Neural Networks (RBFNN), the RBFNN-MFAC method is proposed to improve the performance of the controller. A hydrodynamic model of UVMS was defined in the commercial software, Fluent, to calculate hydrodynamics disturbance, and the mechanism of the dynamic model of UVMS was defined in the commercial software, Adams, to simulate the motion of UVMS. The trajectory tracking performance with various control schemes, including PID (Proportional Integral Derivative), MFAC and RBFNN-MFAC, were analyzed with the Adams and Simulink joint simulation model. The results show that the position tracking accuracy and the speed tracking accuracy with the MFAC control scheme were 68.1% and 81.0% better, respectively, than those with PID control scheme. The position tracking accuracy and the speed tracking accuracy with the RBFNN-MFAC control scheme were 66.3% and 43.1% better, respectively, than those with the MFAC control scheme. The MFAC control scheme and the RBFNN-MFAC control scheme proposed in this paper exhibit good trajectory tracking performance without the precise dynamic model of UVMS, which is of great importance to applications in engineering.
Recent Developments in Botulinum Neurotoxins Detection
Authors: Rasetti-Escargueil Christine , Popoff Michel R.
Published: May 2022

Botulinum neurotoxins (BoNTs) are produced as protein complexes by bacteria of the genus Clostridium that are Gram-positive, anaerobic and spore forming (Clostridium botulinum, C. butyricum, C. baratii and C. argentinense spp.). BoNTs show a high immunological and genetic diversity. Therefore, fast, precise, and more reliable detection methods are still required to monitor outbreaks and ensure surveillance of botulism. The botulinum toxin field also comprises therapeutic uses, basic research studies and biodefense issues. This review presents currently available detection methods, and new methods offering the potential of enhanced precision and reproducibility. While the immunological methods offer a range of benefits, such as rapid analysis time, reproducibility and high sensitivity, their implementation is subject to the availability of suitable tools and reagents, such as specific antibodies. Currently, the mass spectrometry approach is the most sensitive in vitro method for a rapid detection of active or inactive forms of BoNTs. However, these methods require inter-laboratory validation before they can be more widely implemented in reference laboratories. In addition, these surrogate in vitro models also require full validation before they can be used as replacement bioassays of potency. Cell-based assays using neuronal cells in culture recapitulate all functional steps of toxin activity, but are still at various stages of development; they are not yet sufficiently robust, due to high batch-to-batch cell variability. Cell-based assays have a strong potential to replace the mouse bioassay (MBA) in terms of BoNT potency determination in pharmaceutical formulations; they can also help to identify suitable inhibitors while reducing the number of animals used. However, the development of safe countermeasures still requires the use of in vivo studies to complement in vitro immunological or cell-based approaches.

Research on the Coupling between the Double Cycle Mode and Technological Innovation Systems: Empirical Evidence from Data Envelopment Analysis and Coupled Coordination
Authors: Lv Shuang , Zhao Shaodong , Liu Hongda
Published: May 2022

China is striving to build a new dual-circulation development pattern with the aim of leading the coupling of science, technology, and innovation through the active role of financial factors, ultimately promoting the country’s optimal economic development. As a result, this paper constructs a coupled dual-circulation-STI (scientific and technological innovation) relationship model. The domestic and foreign components of the input–output relationship are used to portray the extent of the dual circulation, combined with Index DEA to measure the quality of science and technology innovation under the role of financial factors and the coupled coordination model to analyze the intrinsic correlation between the two. The study used an Index-DEA and value chain analysis model to measure each industry’s technological effectiveness and the degree of internal and external circulation, respectively. The coupled coordination model approach was used to measure the coordination relationship between the double-loop model and technological innovation. Based on the coordination assessment table, the degree of coupling and the natural state of science and technology innovation and dual cycle in each industry were assessed. The study found that the country’s dual-circulation pattern gradually strengthened from 2015–2019, with the financial element also driving an increase in STI. However, due to the twists and turns of the external environment, the coupling power of the dual-circulation STI weakened in some years. On this basis, the paper concludes that the quality of STI, driven by financial factors, has been increasing year on year, and the coupling with dual circulation has been trending upwards. Regarding policy implications, developing countries such as China should continue to invest more financially to create a healthy and sustainable innovation model. Through the innovation-dual-circulation development model, the country should eliminate the sloppy development model in construction and use the power of science and technology to lead social progress.

Published: May 2022

Chemical analysis was performed on sediment samples collected in two sampling sessions (July and October) from Podu Iloaiei Dam Lake, one of the most important water resources used for aquaculture in north-eastern Romania. The concentration of 15 trace elements (TEs), 8 refractory elements (REs), and 15 rare earth elements (REEs)—determined using inductively coupled plasma mass spectrometry—showed variability largely dependent of the sampling points and collection time. Manganese was the most abundant TE, V and Cr were the most abundant REs, while Ce was one of the most abundant REEs. The cerium negative anomaly and Gd positive anomaly were observed in the Chondrite-normalized distributions. In October, the Ce anomaly showed significant negative correlation with Mn, emphasizing the water body oxidation potential. The identified positive Gd anomaly was most likely associated with the use of Gd-chelating agents in magnetic resonance imaging in Iasi, the largest medical hub in north-eastern Romania. Principal component analysis extracted three factors explaining 96.0% of the observed variance, i.e., rock weathering, leaching from soil surface, contributions from urban stormwater and atmospheric deposition (50.9%), pedological contributions (23.7%), and mixed anthropogenic sources (e.g., traffic, waste discharge, agricultural activities; 21.4%). The evaluation of pollution indices highlighted low and moderate degrees of contamination for most of the elements and a considerable degree of contamination for Cd. Assigned Cd sources included fertilizers and pesticides used in the near agricultural areas or the high traffic road located near the lake. Since contamination of aquatic ecosystems with harmful elements is a human health concern, further monitoring of specific vectors in the food chain of the investigated dam lake will be of the utmost importance.

Blood loss in sheep can have different causes and may result in anemia. We aimed to evaluate the clinical, hematological, and biochemical alterations and the oxidative stress generated by acute blood loss. Eighteen healthy sheep underwent phlebotomy to remove 40% of the blood volume and were evaluated clinically and by laboratory tests for clinical, biochemical, and blood gas variables and to assess oxidative stress before induction (T0), 30 min (T30 min), and 6 (T6 h), 12 (T12 h), and 24 h (T24 h) after blood loss. The sheep showed tachycardia from T30 min until T24 h, reduction in the hematocrit, number of erythrocytes, and hemoglobin concentration, with lower values at T24 h and increase in the number of leukocytes from T12 h on. There was a reduction in blood pH and oxygen pressure at T30 min, increased lactate concentration and reduced blood bicarbonate at this time. There was an increase in urea concentration from T6 h until the end of the study, with no change in creatinine levels. The animals did not show changes in the concentration of malonaldehyde, and in the activity of the enzymes superoxide dismutase, glutathione peroxidase, and catalase, but there was a reduction in the concentration of reduced glutathione at T24 h. The acute loss of 40% of blood volume is capable of promoting relevant clinical, hematological, blood gas, and biochemical alterations, and contributed to the appearance of oxidative stress with reduced glutathione concentration, suggesting that this process generated free radicals in sufficient quantity to diminish the action of antioxidants.
PTLchain: Privacy and Traceability Enhanced Scheme for Logistics by using Consortium Blockchain
Authors: LIN Xiaoguo , Wang Xunbing
Published: May 2022

In digital intelligence era, the authenticity , privacy and traceability of data are key factors in building a good logistics information system. However, current logistics system does not pay attention to protecting user’s privacy information, once the user’s privacy is leaked, it will seriously damage the interests of the user. Besides, when there is a logistics dispute, the logistics system cannot ensure the credibility of the traceable process, which reduces the security and availability of the system. Compared with the traditional logistics system, the blockchain-based logistics scheme ensures the security of users’ personal privacy, the authenticity and traceability of logistics information to a certain extent. However, most of the existing blockchain-based privacy-preserving logistics schemes only propose corresponding system models, which cannot be directly applied. Therefore, to address the leaking problems of logistics information in today’s logistics system and inefficiency in tracing the logistics delivery process, we propose a privacy and traceability enhanced scheme for logistics based on consortium blockchain. The blockchain guarantees the authenticity of logistics data through tamper-resistance and traceability, it avoids logistics information and transportation process tampering and supports efficient logistics traceability. Furthermore, we utilize asymmetric encryption and attribute-based encryption to encrypt users’ privacy and logistics information, to protect the private information and realize fine-grained access control. Finally, we implement the prototype system by Hyperledger Fabric platform, and give the performance evaluation to verify the feasibility and practical significance of our scheme.

Problems on the way of digital transformation at Russian industrial enterprises
Authors: Dolzhenko R. A. , Malyshev D. S.
Published: May 2022

The economy of our country and the enterprises that make up its basis are characterized by low indicators of labor productivity. One of the ways to eliminate this problem is the widespread digitalization of processes, which allows for total fixation of all operations, optimization of processes through deep analytics, automation of basic operations, operational restructuring of the strategy for changes predicted by big data analysis systems. For a number of reasons, the processes of digitalization of production, labor relations, financial and other operations are constrained, which does not allow obtaining the necessary effect from the implementation of expensive digital transformation projects. The world of work is one of the areas of promising changes, it is in it, according to experts, that the maximum effect from the digitalization of processes and functions can be manifested, for example: personnel assessment and development, remuneration, fixation of all labor transactions. Through the analysis of constraining factors, as well as an assessment of lost profits, recommendations were formed in the work for the development of directions for the digitalization of production processes at Russian industrial enterprises.

Authors: Shmyreva A. I. , Samokhvalov S. I.
Published: May 2022

The article considers the main factors that have a positive effect on the quantity demanded for cryptocurrency, and information is the primary one. The authors separately consider the use of Bitcoin throughout 2020 as the leading cryptocurrency on the market. The position of the direct dependence of the value of other cryptocurrencies on the behavior of Bitcoin is given. The study shows that in the modern world, cryptocurrency is not only an investment tool but also a payment instrument which gathers momentum. This is evidenced by the annual expansion of the use of cryptocurrency in the market for goods, works and services. Despite the increasing demand for cryptocurrencies, the problem of infrastructure formation remains open. In modern times, cryptocurrency exchanges appear to be a key element of the infrastructure of the cryptocurrency market, their functioning cannot be stabilized in individual states, which leads to the formation of a shadow cryptocurrency market. A significant aspect of the functioning of cryptocurrencies is the difference in the key factors affecting the cryptocurrency market and the securities market. For the first market such a factor is information, for the second – financial position of the issuer of the securities. It shows investors the difference between these segments of the financial market. In the future, with the participation of all elements of the cryptocurrency market, it is possible to form a balanced system that will function steadily under the influence of external factors.

The relevance of the study is due to significant differences in performance assessments based on non-parametric (DEA) and parametric (SFA) approaches. This problem leads to the inadequacy of the interpretation of the efficiency estimates and the incorrectness of the generated management decisions. The article calculates the DEA and SFA indicators of the efficiency for enterprises in six significant sectors of the Russian economy. A comparative analysis of the DEA and SFA estimates of efficiency in the context of industries and size of enterprises is carried out. We show the possibility of their joint use for making management decisions.

Authors: Vetrova E. A.
Published: May 2022

The article considers the preferences received by all participants of financial transactions in the course of implementation of digital technologies. It identifies the opportunity to modify the general marketing banks strategy based on digitalization and, as a result, to change the entire bank system configuration towards the strengthening of corporate banking structures through the creation of digital ecosystems. It was proved that corporate reliability of digital ecosystem in the market of banking services was ensured by absolute minimization of credit and other financial risks, total elimination of bank fraud. The formation of digital ecosystem in DPR based on the institution of Central Republican Bank (CRB) was suggested. It is substantiated that creation of the CRB DPR ecosystem will secure working capital for enterprises and other business entities of this old industrial region and will increase the efficiency of local authorities in provision of social and other essential services to the public.
MATERIALS AND TECHNOLOGY FOR OBTAINING A RECYCLED NOISE PROTECTION PANEL
Authors: Nakhaev M. , Salamanova M.
Published: May 2022

There are thousands of kilometers of noise protection screens around the world along roads, railways and near airports. The use of such screens poses some issues. Barriers often lack the required level of sound absorption and have low durability. Screens can be noise-absorbing, noise-reflecting or both. Sound absorbing materials are used to suppress noise at medium and high frequencies. For sound deadening at low frequencies, resonant absorbers are used; they are Helmholtz resonators combined into a single structure. When panels reach the end of their life cycle, they must be recycled. Separating wood, metal, fiberglass or rock wool slabs wrapped in fiberglass is not easy. The production of mineral fiber requires a lot of energy. A selection of materials has been proposed and the properties of fine-grained concretes for the further manufacture of a noise-protective panel have been investigated. The perforated front and blank rear walls are made of fine-grained basalt fiber-reinforced concrete reinforced with alkali-resistant basalt fibers. The results of studies of fine-grained basalt concrete confirmed the effectiveness of the combined use of basalt fibers and superplasticizer Master Glenium 115. The physical and mechanical characteristics of basalt fiber-reinforced concrete are increased by about 70–80 % compared to traditional concrete, which will further increase the durability of imitation noise protection panels.
Les protections juridictionnelles de l’État étranger aux États-Unis : aperçu du droit et de la pratique américains suite à l’accord du 8 décembre 2014 relatif à l’indemnisation de certaines victimes de la Shoah déportées depuis la France
Authors: Fleury Thibaut Charles

À la suite de plusieurs recours visant à établir devant les juridictions américaines la responsabilité de la SNCF dans les opérations de déportation menées durant la Seconde guerre mondiale, et à en obtenir réparation, la France et les États-Unis ont conclu en 2014 un accord dont l’objet est de permettre une indemnisation amiable des victimes de ces faits tout en «protégeant l’immunité souveraine » de la France. Alors que s’achève le processus d’indemnisation qu’il gouverne, cet accord est l’occasion de revenir sur les protections juridictionnelles que le droit et la pratique américains accordent aux États étrangers et à leurs émanations, en particulier dans le contexte du «contentieux de la Shoah ».
La délimitation des frontières maritimes de la France
Authors: Dobelle Jean-François
Published: May 2022

Compte tenu de la longueur de ses côtes et du nombre de pays dont elle est voisine, la délimitation des frontières maritimes de la France est une oeuvre de longue haleine qui présente d’importants enjeux géographiques, juridiques, économiques et politiques. À l’exception d’un cas dans lequel des considérations d’opportunité ont prévalu, la France applique les règles et principes du droit international public applicables en la matière. Ce droit est principalement prétorien, et la jurisprudence en ce domaine est abondante. Après avoir fluctué entre la fin des années 1960 et le début des années 1980, elle semble s’être durablement stabilisée depuis un peu plus de deux décennies. L’équidistance n’est certes pas une règle, mais elle constitue une méthode à laquelle, sauf circonstances exceptionnelles, il convient de recourir en premier lieu, quitte à la corriger, dans une seconde étape, principalement pour des raisons d’ordre géographique, afin de parvenir à une solution équitable. Plus des trois-quarts des accords conclus par la France à ce jour retiennent d’ailleurs l’équidistance. Si la France a aujourd’hui passé 37 accords de délimitation maritime, il lui en reste encore une bonne dizaine à conclure, ce qui ne sera pas nécessairement chose aisée : en effet, la délimitation des frontières maritimes peut se heurter à toute une série d’obstacles, techniques certes, mais surtout juridiques et politiques, en particulier quand il existe un désaccord entre les parties concernées sur la teneur de la solution équitable, ou lorsque les espaces maritimes en question se situent au large d’un territoire qui fait l’objet d’une revendication. L’extension du plateau continental au-delà de deux cents milles marins constitue en quelque sorte une «nouvelle frontière » qui entraînera souvent de nouveaux exercices de délimitation.
Relaciones sociales y procesos de salud/enfermedad: las razones y los hechos
Authors: Menéndez Eduardo L.
Published: May 2022

Entre las décadas de 1940 y 1970, las más importantes corrientes teóricas en antropología social y sociología daban gran importancia a las relaciones sociales; pero a partir de mediados de 1970 y sobre todo de la década de 1980, toda una serie de tendencias recuperaron el papel del sujeto y del actor social, cuestionando las corrientes previas, y formulando aproximaciones metodológicas arelacionales. Esta polarización ha sido negativa, por lo que habría que impulsar una articulación entre el enfoque relacional y el basado en el punto de vista del actor.
