Authors:   University of Illinois at Urbana-Champaign, Qamhia Issam , Tutumluer Erol ,   University of Illinois at Urbana-Champaign
Published: May 2021

This report presents findings on the evaluation of foundation layers under concrete pavements in the state of Illinois. It also provides recommendations and scenarios where unbound granular layers can be safely used under concrete pavements as economical and well-performing subbase layers. The current practice and mechanistic design methods for constructing concrete pavements in Illinois was first evaluated, including historical studies that led to the current design procedures and policies. The performance of concrete pavements with unbound granular layers in Illinois were then evaluated, and several case studies of well-performing concrete pavements with granular subbases, high traffic levels, and low distress levels and severity were realized. Next, the practices of surrounding states were evaluated, and several Midwest states, i.e., Wisconsin, Minnesota, Iowa, and Michigan, were found to regularly use unbound granular layers under concrete pavements with no issues. A literature review on the most recent requirements and recommendations for designing granular subbases under concrete pavements was then presented. It is concluded that subbase layers under concrete pavements are mainly used to provide uniform support and prevent pumping. Based on the case study evaluations and literature, a stable, drainable, and durable daylighted granular subbase design is recommended for traffic factors up to 10.0. Stability is ensured by limiting the ratio of gravel-to-sand fractions in the aggregate mix between 1.3 and 1.9. Drainability requirements can be met by limiting the percentage of fines passing the No. 200 sieve (0.075 mm) to 4% and by checking the quality of drainage is at least fair based on the time required to drain 50% of the water. Lastly, a geotextile fabric is recommended for use below the granular subbase for separation to ensure drainability throughout design life.

Brandschutz für stationäre Lithium-Ionen-Batterie-Energiespeichersysteme
Authors: Meißner Carsten
Published: May 2021

Die aktuellen Normen & Richtlinien wie beispielsweise die Betriebssicherheitsverordnung (BetrSichV), Niederspannungsrichtlinie 2014/35/EU sowie die EMV-Richtlinie für elektromagnetische Verträglichkeit (EMV-Richtlinie 2004/108/EG) bilden ein gutes Grundgerüst, zeigen aber zeitgleich auf, dass es für stationäre Lithium-Ionen-Energiespeichersysteme noch nicht die Richtlinien für ein umfassendes Brandschutzkonzept gibt. Aus brandschutztechnischer Sicht stellen diese Container hohe und komplexe Anforderungen dar. Ein VdS-anerkanntes, von Siemens entwickeltes Schutzkonzept erfüllt über die aktuellen Richtlinien hinaus spezifische Anforderungen für Lithium-Ionen Speicher durch die Kombination leistungsfähiger Detektions- und Löschtechnik.

The landscape below the Tinglev outwash plain: a reconstruction
Authors: Friborg Rud
Published: May 2021

The Tinglev outwash plain is situated in the southemmost part of Jutland, Denmark, and continues southwards across the Danish-German border. Traditionally
the melt water deposits between ground surface and the uppermost till are referred to the Weichselian. This paper shows that the melt water sediments can be
separated into two outwash plains. The upper one being deposited in the Weichselian, the lower one in the Saalian. To the west the outwash plains are separated
by marine Eemian sediments. Further eastwards the units may be distinguished
by lirnnic Eemian deposits as well as Eemian weathering horizons. The paper
presents contour maps showing the surface of the uppermost till, a map showing
the extension of the marine Eemian in situ, isopach maps of the two outwash
plains and a map showing the extension of the Saalian outwash plain.

Component Contribution to the Total Reliability of the WAMS Network
Authors: Uspensky M.I.
Published: May 2021

Nowadays, the control of power systems relies on wide-area monitoring and control system (WAMS), which continuously measures and registers state vector values and is synchronized by signals from the uniform time system. A significant part of this system is the local information network, whose reliability largely determines the proper functioning of WAMS. One can assess the said reliability by dividing it into components. These are hardware or technical reliability associated with failure (destruction) of transmission channel elements or the integrity of communication lines, traffic reliability determined by time loss or data distortion without failure of a transmission channel element, software reliability related to errors in the development of exchange execution programs, and resilience against an external deliberate impact on the transmitted information. This paper addresses the assessment of the first three reliability components of the information network, shows its total value, and estimates the contribution of each component. The last component (resistance to an external deliberate action) is described in a huge number of works, which is why it is not considered in this paper.

An Empirical Proxy for the Second Integral of Motion in Rotating Barred or Tri-axial Potentials
Authors: Qin Yu-Jing , Shen Juntai
Published: May 2021

We identify an effective proxy for the analytically unknown second integral of motion (I
2) for rotating barred or tri-axial potentials. Planar orbits of a given energy follow a tight sequence in the space of the time-averaged angular momentum and its amplitude of fluctuation. The sequence monotonically traces the main orbital families in the Poincaré map, even in the presence of resonant and chaotic orbits. This behavior allows us to define the calibrated angular momentum, the average angular momentum (

) normalized by the amplitude of its fluctuation (

), as a numerical proxy for I
2. It also implies that the amplitude of fluctuation in L

z
, previously underappreciated, contains valuable information. This new proxy allows one to classify orbital families easily and accurately, even for real orbits in N-body simulations of barred galaxies. It is a good diagnostic tool of dynamical systems, and may facilitate the construction of equilibrium models.
Mobile, Open and Social Language Learning Designs and Architectures
Authors: Kukulska-Hulme Agnes , Arus-Hota Jorge , Garcia Laborda Jesus
Published: May 2021

The emerging paradigm of mobile open social learning for languages (MOSL4L) integrates the three elements of mobile, open and social, and in so doing it creates the idea of a conceptually different language learning space. It is a space full of opportunity and challenge, relevant to a post-pandemic world in which we are looking for ways to build back better. The paper discusses tensions between formal and informal language learning and the nature of learning outcomes in MOSL4L. It focuses on the needs of individuals while also considering the characteristics of the virtual spaces in which they participate. It highlights the potential of micro experiences and learning moments as structures that are well aligned with MOSL4L. It suggests developments in language curricula to take account of communication challenges being identified in the contemporary world. Many more new learning designs and software architectures will have to be developed to match the possibilities generated by the MOSL4L space.

Pragmatisme, positivisme et vérification : Peirce critique de Comte
Authors: Girel Mathias
Published: May 2021

L’article étudie la relation de Peirce à Comte, en partant des critiques formulées dans ses écrits de jeunesse. Son enjeu est double : il relève d’abord d’une question d’histoire de la philosophie étonnamment peu traitée, alors même que Peirce lit, commente et critique Comte. Le second enjeu est épistémologique et métaphysique : Peirce voit dans la théorie comtienne des hypothèses une position proche du pragmatisme qu’il développe, mais grevée de présupposés nominalistes qui la rendent finalement intenable, à moins que l’on n’en adopte une lecture « charitable ». La confrontation avec Comte semble alors être l’occasion privilégiée d’une explicitation de son propre pragmatisme.
Chrysippe, les possibles et l’éternel retour
Authors: D’Jeranian Olivier
Published: May 2021

Chrysippe a élaboré une stratégie contre l’argument Dominateur de Diodore afin d’éviter le nécessitarisme impliqué par le rejet des possibilités contrefactuelles. Alexandre d’Aphrodise lui oppose sa doctrine du retour périodique (Sur les Premiers Analytiques d’Aristote 180, 28 – 181, 34). Son objection repose sur une conception numérique de l’identité des individus à travers les cycles. Chrysippe n’admettant que leur ressemblance sinon leur stricte identité qualitative, sa doctrine du retour autorise les possibilités contrefactuelles.

Les arts énergétiques dans le dialogue des paradigmes scientifiques : bilan d’étape des bénéfices des disciplines corps-esprit (Yoga, Tai-chi, Qi-gong)
Authors: Guyon Alice , Ravenet Jérôme , Midol Nancy
Published: May 2021

La définition des pratiques des arts énergétiques indiens ou chinois se heurte à un double problème, taxinomique et axiologique. Elle est au cœur d’un dialogue des cultures scientifiques d’Orient et d’Occident qui permet de dépasser le « choc » des civilisations. Dans cet article, nous proposons un bilan d’étape sur les bienfaits de ces pratiques du point de vue des neurosciences et des sciences cognitives, qui pourrait contribuer à réconcilier le mécanisme et le vitalisme, aider à dépasser le dualisme de la matière et de l’esprit, l’opposition qualité/quantité, holisme/réductionnisme... Bref, à marier les paradigmes de la science occidentale et de la science orientale pour s’inscrire dans une perspective de sport durable.

Vacances adaptées : allier liberté et sécurité
Authors: Mortreuil Christian
Published: May 2021

L’association Handi-Loisirs organise depuis 1986 des séjours de vacances pour des adultes handicapés vivant pour la plupart en établissements spécialisés. Les animateurs (souvent des éducateurs en cours de formation) qui encadrent ces séjours proposent aux vacanciers des sorties et activités. Ils doivent être vigilants à ce que les relations qui peuvent s’établir entre les vacanciers, qu’ils arrivent ou non en couple, soient librement consenties. Les rapports de domination sont peu fréquents, les handicapés étant moins influencés par les stéréotypes du masculin et du féminin.
La souffrance des enseignants, reflet d’une société en perte de repères
Authors: Gallard Béatrice
Published: May 2021

Ils sont de plus en plus nombreux à tirer la sonnette d’alarme et à crier leur mal-être. Les enseignants en souffrance constatent avec impuissance l’infiltration des valeurs économiques du néo--libéralisme dans le corporatisme enseignant. Leurs mécanismes de défense sont des tentatives de réponse à cette souffrance qui les épuise. L’accompagnement psychologique devient dès lors indispensable, alors que nous devrions nous interroger au préalable sur ce qui, de l’organisation du travail, devrait être modifié.

Nobody Wants to Talk About Dying: Facilitating End-of-Life Discussions
Authors: Barra Maryanne
Published: May 2021

Background:

This educational study investigated the association between nursing staff and end-of-life discussions in an assisted living facility. Although mandated, these conversations often are deficient due to health care providers' limited knowledge on advance care documents.

Method:

All staff underwent end-of-life training to identify their own reservations that prevent involvement with advance directive completion, develop advance directive competency, recognize the ramifications when advance directives are not documented, and role-play to experience different character viewpoints.

Results:

The group discussions and interview data were summarized into four main themes: not qualified to broach the end-of-life documents; reluctance to get involved; right place, right time, and right words; and who wants to think about death? Eleven subthemes that detailed descriptions from each category also were identified.

Conclusion:

Staff acknowledged the value of in-service education to alleviate their uncertainty on the subject matter, gaining confidence, proficiency, and perspectives with end-of-life planning.

L’Adaptation du Colomba de Prosper Mérimée par Germaine Dulac
Authors: Bonnot-Gallucci Valécien
Published: May 2021

En 1938 Germaine Dulac, directrice des actualités Gaumont, entreprend, avec Marie-Anne Malleville, d’adapter Colomba, une nouvelle de Prosper Mérimée située en Corse. Ce projet mené jusqu’à la veille du tournage ne verra pas le jour. Cet article exploite le fonds Dulac de la Cinémathèque française, où se trouve une continuité dialoguée, un découpage technique et des synopsis dans un dossier intitulé « Rimbecco » (qui signifie l’appel à la vengeance), afin d’examiner la nature de ce projet qui, comme la Carmen de Feyder pour l’Andalousie, convoque un document littéraire afin d’évoquer l’actualité de la Corse. Le récit envisagé est, en effet, situé en 1938 : il s’agit de créer un scénario « moderne » adapté aux « mœurs actuelles de la Corse », trouver dans ses paysages et ses coutumes matière à narration. Ainsi la transcription des voix populaires, l’enregistrement des chants, des sons, des lieux de tournage sont-ils privilégiés dans une approche de nature documentaire. Par ailleurs, à l’encontre de la représentation misogyne de la femme fatale de Mérimée, Dulac réinvente une « Colomba 38 » (un des titres envisagés) qui est une figure féministe.
L’art populaire au Brésil et le musée Casa do Pontal
Authors: Mascelani Angela
Published: May 2021

En examinant comment la notion d’art populaire a pris forme au Brésil, cet article permet de constater que les figurines, et sculptures réalisées par des personnes appartenant aux classes populaires peuvent être vues comme des productions artistiques. En parallèle, il met en lumière les efforts déployés par le Museu Casa do Pontal, depuis sa création par Jacques Van de Beuque en 1976, et, après lui, au cours de ces vingt dernières années. Il montre notamment comment l’institution a contribué à une plus grande appréciation de cette production et a œuvré pour la reconnaissance du rôle des artistes et la diffusion qualifiée de leurs créations, tout en insistant sur l’attribution de leurs autorités respectives.
Un peu de Brésil à Newmarket : notes sur la circulation internationale des travailleurs de la filière équine
Authors: Adelman Miriam
Published: May 2021

Cet article examine un contexte particulier de travail avec les chevaux permettant la conversion du « capital équin » issu de la culture rurale brésilienne en un ensemble de compétences réutilisables à l’étranger. Il rejoint d’autres études sur la mobilité de certains travailleurs contemporains, notamment dans le domaine du sport mondial. Les trajectoires singulières de personnes qui, grâce au cheval, cherchent à se stabiliser et à se réaliser apparaissent pertinentes pour les débats en cours sur la mondialisation de la vie sociale.

NF-κB plays a crucial role in regulating cell proliferation, inflammation, apoptosis, and immune responses. HSV type 2 (HSV-2) is one of the most predominant sexually transmitted pathogens worldwide, and its infection increases the risk of HIV type 1 (HIV-1) acquisition and transmission. HSV-2 glycoprotein D (gD), highly homologous to HSV-1 gD, is essential for viral adhesion, fusion, entry, and spread. It is known that HSV-1 gD can bind herpesvirus entry mediator (HVEM) to trigger NF-κB activation and thereby facilitate viral replication at the early stage of infection. In this study, we found that purified HSV-2 gD triggered NF-κB activation at the early stage of infection, whereas ectopic expression of HSV-2 gD significantly downregulated TNF-α–induced NF-κB activity as well as TNF-α–induced IL-6 and IL-8 expression. Mechanistically, HSV-2 gD inhibited NF-κB, but not IFN-regulatory factor 3 (IRF3), activation and suppressed NF-κB activation mediated by overexpression of TNFR-associated factor 2 (TRAF2), IκB kinase α (IKKα), IKKβ, or p65. Coimmunoprecipitation and binding kinetic analyses demonstrated that HSV-2 gD directly bound to the NF-κB subunit p65 and abolished the nuclear translocation of p65 upon TNF-α stimulation. Mutational analyses further revealed that HSV-2 gD interacted with the region spanning aa 19–187 of p65. Findings in this study together demonstrate that HSV-2 gD interacts with p65 to regulate p65 subcellular localization and thereby prevents NF-κB–dependent gene expression, which may contribute to HSV-2 immune evasion and pathogenesis.

Protective immunity against COVID-19 likely depends on the production of SARS-CoV-2–specific plasma cells and memory B cells postinfection or postvaccination. Previous work has found that germinal center reactions are disrupted in severe COVID-19. This may adversely affect long-term immunity against reinfection. Consistent with an extrafollicular B cell response, patients with severe COVID-19 have elevated frequencies of clonally expanded, class-switched, unmutated plasmablasts. However, it is unclear whether B cell populations in individuals with mild COVID-19 are similarly skewed. In this study, we use single-cell RNA sequencing of B cells to show that in contrast to patients with severe COVID-19, subjects with mildly symptomatic COVID-19 have B cell repertoires enriched for clonally diverse, somatically hypermutated memory B cells ∼30 d after the onset of symptoms. This provides evidence that B cell responses are less disrupted in mild COVID-19 and result in the production of memory B cells.

Published: May 2021

Background:

Chronic kidney disease (CKD) impacts hugely on cardiovascular morbidity and mortality. Nigerian data on patterns and predictors of left ventricular hypertrophy (LVH) in persons living with CKD are scarce. The objective of the study is to describe the patterns and predictors of LVH in Nigerians with CKD.

Methods:

Recruitment and clinical assessment of adult Nigerians with CKD were done using standard procedures. Statistical analysis was done using appropriate statistical software.

Results:

Fifty-seven participants were involved in this study. Concentric and eccentric LVH occurred in 50% and 25% of the predialysis CKD patients, respectively, while 24% and 36% of the maintenance dialysis CKD patients had concentric and eccentric LVH, respectively. LVH patterns in dialysis-naive individuals were not significantly different from LVH patterns in persons on dialysis. The significant predictors of LVH in study participants were proteinuria, anemia, hypoalbuminemia, estimated glomerular filtration rate <30 mL/1.73 m2/min, and hypertensive nephrosclerosis. High calcium-phosphate product was a significant predictor of LVH in only participants on dialysis.

Conclusion:

This study showed no significant difference in LVH patterns among predialysis and maintenance dialysis CKD patients. Indices of deteriorating renal function were significant predictors of LVH in both categories of CKD patients. Early screening and treatment of significant risk factors of LVH are required in reducing CVD burden among CKD patients.
Role of Interictal Arterial Spin Labeling Magnetic Resonance Perfusion in Mesial Temporal Lobe Epilepsy
Authors: Mittal Ashima , Singh Dhanota Devinder Pal , Saggar Kavita , Singh Gagandeep , Ahluwalia Archana
Published: May 2021

Context:

Electrophysiological and hemodynamic data can be integrated to accurately identify the generators of abnormal electrical activity in drug-resistant focal epilepsy. Arterial Spin Labeling (ASL), a magnetic resonance imaging (MRI) technique for quantitative noninvasive measurement of cerebral blood flow (CBF), can provide a direct measure of variations in cerebral perfusion associated with the epileptogenic zone.

Aims:

1. To evaluate usefulness of ASL for detecting interictal temporal hypoperfusion to localize the epileptogenic zone in patients of drug resistant mesial temporal lobe epilepsy (MTLE). 2. Correlation of localization of epileptogenic zone on ASL MR perfusion with structural MRI and EEG.

Methods and Materials:

30 patients with MTLE and10 age and gender matched normal controls were studied. All patients underwent ictal video EEG monitoring non-invasively, MR imaging with epilepsy protocol and pseudocontinuous ASL (PCASL) perfusion study. Relative CBF (rCBF) values in bilateral mesial temporal lobes were measured utilizing quantitative analysis of perfusion images. A perfusion asymmetry index (AI) was calculated for each region.

Results:

In patients, ipsilateral mesial temporal rCBF was significantly decreased compared with contralateral mesial temporal rCBF (p = 0.021). Mesial temporal blood flow was more asymmetric in patients than in normal control participants (p = 0.000). Clear perfusion asymmetry on PCASL-MRI was identified despite normal structural-MRI in 5 cases, agreeing with EEG laterality.

Conclusions:

Pseudo-continuous ASL offers a promising approach to detect interictal hypoperfusion in TLE and as a clinical alternative to SPECT and PET due to non-invasiveness and easy accessibility. Incorporation of ASL into routine pre-surgical evaluation protocols can help to localize epileptogenic zone in surgical candidates.
Filippov trajectories and clustering in the Kuramoto model with singular couplings
Authors: Park Jinyeong , Poyato David , Soler Juan
Published: May 2021

We study the synchronization of a generalized Kuramoto system in which the coupling weights are determined by the phase differences between oscillators. We employ the fast-learning regime in a Hebbian-like plasticity rule so that the interaction between oscillators is enhanced by the approach of phases. First, we study the well-posedness problem for the singular weighted Kuramoto systems in which the Lipschitz continuity fails to hold. We present the dynamics of the system equipped with singular weights in all the subcritical, critical and supercritical regimes of the singularity. A key fact is that solutions in the most singular cases must be considered in Filippov’s sense. We characterize sticking of phases in the subcritical and critical case and we exhibit a continuation criterion for classical solutions after any collision state in the supercritical regime. Second, we prove that strong solutions to these systems of differential inclusions can be recovered as singular limits of regular weights.We also study the emergence of synchronous dynamics for the singular and regular weighted Kuramoto models.

Published: May 2021

Background: The information currently available concerning carbon nanotubes toxicity is disturbing and conflicting. Moreover, little is known about their effect on the nasal cavities, which are the first target for nanoparticles. Material and method: We investigated the cytotoxicity (50 to 0.5 microg/mL) of double-walled carbon nanotube with two independent tests (MTT, Wst-1) on normal human nasal epithelial cells after 12-day exposure (control untreated nasal cells and A549). Nasal cell differentiation function, oxidative stress, the morphological features of cells in contact with DWCNTs and the localizations of the latter were also investigated. Results: Exposure revealed a dose-dependent decrease in cell metabolic activity and cell growth. In nearly all conditions, normal human nasal epithelial cells were more sensitive than malignant ones. Even with both tests, the cytotoxic threshold dose could not be accurately determined because of dye adsorption by DWCNTs. Nasal cells showed stronger cytokeratin 7 and persistent UEA-I immunostaining. Cytokeratin 19 production was increased at 25 microg/mL and mucus production was stimulated from 0.5 microg/mL. A significant increase in Reactive Oxygen Species was observed from 25 microg/mL. The cell plasma membrane showed several holes and DWCNTs were present in the cytoplasm. Conclusion: DWCNTs seem to have a deleterious effect on nasal cells after 12-day exposure.
