La Dame à la licorne, sa conservation et l’évaluation colorimétrique du nettoyage
Authors: Taburet-Delahaye Élisabeth , Déjean Raphaëlle , Reyer Dominique de , Nowik Witold
Published: March 2021

Les six tapisseries de la tenture de La Dame à la licorne forment un ensemble exceptionnel à bien des égards : une iconographie abondamment commentée, une histoire mouvementée, une qualité d’exécution remarquable. Malgré la grande vigilance déployée à leur égard, leur état nécessitait des interventions de conservation qui devaient également orienter les choix muséographiques de la salle rénovée. Des analyses colorimétriques ont permis d’apprécier l’efficacité du lavage préconisé en raison de leur état sanitaire, mais également de définir un référentiel pour le suivi futur de leur état de surface.
La restauration d’une tapisserie bruxelloise de la Renaissance par traitement enzymatique
Authors: Forestier Sylvie , Bos Agnès
Published: March 2021

Une petite tapisserie bruxelloise du xvie siècle, tissée en laine, soie, et comportant des filés métalliques, appartenant au musée du Louvre, a fait l’objet en 2009-2010 d’une restauration particulière. La pièce, tendue sur un châssis de bois, s’était déformée, les fibres étaient devenues fragiles et cassantes, offrant en outre un aspect jauni et terne. Le revers était en effet couvert d’un épais badigeon de colle qui avait imprégné profondément les fibres. Éliminer cette colle était nécessaire avant d’entreprendre une consolidation des parties fragiles et d’envisager une nouvelle présentation de la tapisserie.Des essais de traitement avec une enzyme α-amylase ont été entrepris afin d’établir la faisabilité d’un tel traitement et les paramètres appropriés. Le badigeon de colle a été éliminé par immersion de la tapisserie dans une solution tamponnée contenant l’α-amylase. La tapisserie a ensuite pu être consolidée puis doublée afin de pouvoir être de nouveau présentée.

Le musée des Archives nationales conserve un paravent (n° inv. AE/Vla/15) orné de peintures chinoises d’exportation (China Trade) qui porte l’estampille d’un ébéniste parisien de la fin du xviiie siècle. Son état préoccupant a conduit les Archives à commander, en novembre 2012, une étude technique préalable à la restauration accompagnée d’une proposition de traitement. Celle-ci a été confiée à Patricia Dal-Prà et à Janin Bechstedt et a été réalisée dans les ateliers du C2RMF dont le département Recherche a effectué les analyses scientifiques. Elle a été complétée en 2013 par une étude iconographique menée par Hélène Gascuel.

Développement d’une nouvelle méthode de désinsectisation sous vide partiel des objets du patrimoine en bois
Authors: Caillat Loïc , Chaumat Gilles , Blanc Lionel , Guiblain Thomas
Published: March 2021

ARC-Nucléart a entrepris de mettre au point un procédé original de désinsectisation sous vide partiel, efficace à la fois pour les larves et les œufs d’insectes. Le principe de ce traitement est de réaliser un vide partiel autour des objets pour dessécher les insectes (eau libre) sans dessécher le bois (eau liée). Le dispositif est principalement constitué d’une enceinte sous vide partiel (inférieur à 100 mbar) permettant de contrôler l’humidité ambiante (entre 40 et 60 % HR). Une importante campagne d’essais a été effectuée pour valider le procédé avec plus de deux mille plaquettes de différentes essences de bois moderne, avec ou sans polychromie. L’étude réalisée a permis de démontrer qu’il était possible de mettre en œuvre un traitement à basse pression (50 mbar), à température ambiante (entre 20 et 25 °C), pour désinsectiser des objets en bois rapidement (quelques jours) avec une efficacité satisfaisante. Le deuxième constat important de ces travaux est qu’un traitement à basse pression a permis de respecter les polychromies des objets lorsque l’humidité dans l’enceinte était régulée.
FAST INTERACTIVE REGIONAL PATTERN MERGING FOR GENERIC TISSUE SEGMENTATION IN HISTOPATHOLOGY IMAGES
Authors: Lor Kuo-Lung , Chen Chung-Ming
Published: March 2021

The image segmentation of histopathological tissue images has always been a challenge due to the overlapping of tissue color distributions, the complexity of extracellular texture and the large image size. In this paper, we introduce a new region-merging algorithm, namely, the Regional Pattern Merging (RPM) for interactive color image segmentation and annotation, by efficiently retrieving and applying the user’s prior knowledge of stroke-based interaction. Low-level color/texture features of each region are used to compose a regional pattern adapted to differentiating a foreground object from the background scene. This iterative region-merging is based on a modified Region Adjacency Graph (RAG) model built from initial segmented results of the mean shift to speed up the merging process. The foreground region of interest (ROI) is segmented by the reduction of the background region and discrimination of uncertain regions. We then compare our method against state-of-the-art interactive image segmentation algorithms in both natural images and histological images. Taking into account the homogeneity of both color and texture, the resulting semi-supervised classification and interactive segmentation capture histological structures more completely than other intensity or color-based methods. Experimental results show that the merging of the RAG model runs in a linear time according to the number of graph edges, which is essentially faster than both traditional graph-based and region-based methods.
Mercury methylation in oxic aquatic macro-environments: a review
Authors: Gallorini Andrea , Loizeau Jean-Luc
Published: March 2021

Mercury methylation in aquatic environments is a key process that incorporates this neurotoxin into the food chain and ultimately the human diet. Mercury methylation is considered to be essentially biotic and mainly driven by sulfate-reducing bacteria present in the bottom sediments in aquatic systems. However, in recent decades, many researchers have shown that this methylation also occurs in oxic layers in conjunction with a high content of particulate organic matter and localized depletion of dissolved oxygen. The goals of this review are to summarize our current understanding of Hg methylation in water columns of both marine and freshwater environments, as well as to highlight knowledge gaps and future research needs. Most of the literature showed that suspended particles (known as marine and lake snow) could be the microenvironment in which Hg methylation could occur across oxic water columns, because they have been recognized as a site of organic matter mineralization and as presenting oxygen gradients around and inside them. To date, the majority of these studies concern marine environments, highlighting the need for more studies in freshwater environments, particularly lacustrine systems. Investigating this new methylmercury production environment is essential for a better understanding of methylmercury incorporation into the trophic chain. In this review, we also propose a model which attempts to highlight the relative importance of a MeHg epilimnetic path over a MeHg benthic-hypolimnetic path, especially in deep lakes. We believe that this model could help to better focus future scientific efforts in limnic environments regarding the MeHg cycle.

Background

The safety of healthcare workers exposed to formaldehyde remains a great matter of concern for healthcare management units. This work aimed at describing the results of a combined monitoring approach (environmental and biological) to manage occupational exposure to formaldehyde in a hospital setting.

Design and methods

Environmental monitoring of working spaces and biological monitoring of urinary formaldehyde in 16 exposed healthcare workers of the Anatomic Pathology Unit of a University Hospital in Southern Italy was performed on a fouryear timescale (2016-2019).

Results

Values of aero-dispersed formaldehyde identified were on average low; although workers’ urinary formaldehyde levels were also minimal, the statistical analysis highlighted a slight weekly accumulation.

Conclusions

Our data confirm that both environmental and biological monitoring are important to identify risk situations, in particular when values of hazardous compounds are below the accepted occupational exposure levels.
Intermittent sympathetic stimulation
Authors: Shankar Guruprasad Hassan , Thomas Arun , Santhikrishna V. , Venkatesha Gurudutt Avati
Published: March 2021

Neurological symptoms are documented in intestinal pathologies; however pure neurological presentation in abdominal conditions are rare and presenting with intermittent autonomic disturbances are extremely rare. Here we describe two cases with intestinal obstruction and intussusception who had intermittent hypertension and tachycardia. Diagnosis in both the children were initially challenging, especially so in the first case as the child presented with only neurological symptoms. The exact pathogenesis of this sympathetic overdrive is not known and requires more studies to evaluate the cause. In both the kids, once the primary pathology was treated, the children became neurologically better and has been fine on follow up.

Published: March 2021

As the COVID-19 pandemic evolves, an increasing number of concurrent associations are being reported including several postinfectious phenomena. The role of diabetes mellitus (DM) and its implications in increased severity and mortality of adults with COVID-19 is established. COVID-19 is known to cause hyperglycemia and worsen glycemic control in adults with active infection. However, the association in pediatric population is not well established. The interplay between biological, psychosocial, and economic factors for increased association of COVID-19 with Type 1 DM and/or presentation with diabetic ketoacidosis (DKA) is not clear. We briefly describe a surge in the number of children with DKA as experienced in our center in the course of the ongoing pandemic with a brief evaluation of all the abovementioned factors.

Published: March 2021

Background:

The risks of femoral arterial line placement in young children have been incompletely defined. We hypothesized that a low complication rate would be associated with ultrasound use.

Subjects and Methods:

Infants aged 0–12 months undergoing placement of a femoral arterial line at our institution over a 3.5-year period were identified through billing data, and their records were reviewed. Events concerning each line were recorded individually. Patients were excluded if there was incomplete documentation or if the line was in place for under 24 h. Demographics, information about line placement, and complications were recorded.

Results:

Three hundred and sixty-four femoral arterial lines were included. Eighty percent of lines were placed in the operating room, with the rest placed in the cardiac intensive care unit (ICU) (11%), the cardiac catheterization lab (6%), or the pediatric ICU (3%). Femoral artery occlusion occurred with 16% of lines placed, and limb ischemia in 6%. One patient had tissue loss. Occlusion was associated with lower gestational age at birth (44 [40–57] vs. 50 [41–60], P = 0.04), lower weight (3.7 [3.1–5.7] vs. 4.3 kg [3.3–6.2], P = 0.05), left-sided lines (52% vs. 66%, P = 0.05), placement in interventional catheterization lab (odds ratio [OR]: 3.28, confidence interval [CI]: 1.24–8.67, P = 0.02), >2 attempts (27% vs. 13%, P < 0.01), and catheter diameter (OR: 2.86, CI: 1.18–6.92, P = 0.02).

Conclusion:

Femoral arterial catheter placement in infants younger than 12 months resulted in a 16% rate of arterial occlusion at our institution, which was associated with low gestational age, larger catheter size, and left-sided lines but not ultrasound use, line duration, catheter length, use of anticoagulation, physician specialty, or physician training level.

Nodal line estimates for the second Dirichlet eigenfunction
Authors: Beck Thomas , Canzani Yaiza , Marzuola Jeremy L.
Published: March 2021

We study the nodal curves of low energy Dirichlet eigenfunctions in generalized curvilinear quadrilaterals. The techniques can be seen as a generalization of the tools developed by Grieser–Jerison in a series of works on convex planar domains and rectangles with one curved edge and a large aspect ratio. Here, we study the structure of the nodal curve in greater detail, in that we find precise bounds on its curvature, with uniform estimates up to the two points where it meets the domain at right angles, and show that many of our results hold for relatively small aspect ratios of the side lengths. We also discuss applications of our results to Courant-sharp eigenfunctions and spectral partitioning.

Random Walks in Hypergraph
Authors: Bellaachia Abdelghani , Al-Dhelaan Mohammed
Published: March 2021

Random walks on graphs have been extensively used for a variety of graph-based problems such as ranking vertices, predicting links, recommendations, and clustering. However, many complex problems mandate a high-order graph representation to accurately capture the relationship structure inherent in them. Hypergraphs are particularly useful for such models due to the density of information stored in their structure. In this paper, we propose a novel extension to defining random walks on hypergraphs. Our proposed approach combines the weights of destination vertices and hyperedges in a probabilistic manner to accurately capture transition probabilities. We study and analyze our generalized form of random walks suitable for the structure of hypergraphs. We show the effectiveness of our model by conducting a text ranking experiment on a real world data set with a 9% to 33% improvement in precision and a range of 7% to 50% improvement in Bpref over other random walk approaches.

Published: March 2021

Nowadays, the exploitation of augmented reality in education is linked to a multitude of pedagogical subjects, including history, geography, natural sciences and arts. The extensive use of computers in the educational process in recent years, in addition to learners’ familiarity with the use of Internet and applications associated with its operation, have led to a search for creative methods, which will enhance interaction in the pedagogical approach. As a result, a digital learning environment has emerged in which trainees gain access to knowledge in an entertaining and interactive way by making use of innovations and gaining the ability to control their knowledge. The purpose of this paper is to feature the role of new technologies in the educational process by studying the use of augmented reality applications in teaching history. Designing such applications requires direct involvement of the teacher and, as established by the case study, the benefits are extremely important; students acquire a particular interest in the learning object and achieve higher performance, as compared to conventional forms of teaching.
The dendrometric characteristics of oak woods in rural landscapes of the East Carpathians
Authors: Dudek Tomasz , Korol Mykola , Havryliuk Serhii , Dychkevych Vasyl , Bobiec Andrzej
Published: March 2021

The dendrometric characteristics are functions of tree age and ecological growth conditions. On relatively small areas of homogeneous sites, the stand age structure and the phytosocial interaction between the trees are the major factors influencing the stand characteristics. We hypothesise that the correlation between the basic dendrometric variables and tree age can be used as a yardstick discriminating silvopastoral oak woods from silvicultural stands managed for timber. The tree age, diameter at breast height (DBH), and height (H) were determined in 14 silvopastoral oak woods in the East Carpathian region, which were compared to the respective forest inventory data of 31 silvicultural oak stands. The correlation between DBH, H and their ratio – the slenderness index (si) and age of oaks – were very weak and insignificant compared to the conspicuous age effect on the dendrometric features in the forestry-grown stands, which can be explained by a more complex development dynamics and spatial structure of silvopastoral woods. The study implies that the habitat conditions and processes related to traditional husbandry are better harmonised with the intrinsic oak ecological adaptations than modern silvicultural treatments. Therefore, we advise to promote the revival of silvopastoralism in the Carpathian region as a cost-efficient way of perpetuating the rural ‘oakscape’, an outstanding bio-cultural landscape asset.  Keywords: slenderness index, height-diameter, oak, cultural landscape, agroforestry, cattle grazing, wood-pastures
Reconstituição espaço-temporal do Alagado do Piry de Jussara, Belém-PA: evolução e impacto na urbanização
Authors: Silva Marcus Vinicius Silva da , Lima Aline Maria Meiguins de
Published: March 2021

Historicamente, a cidade de Belém tem lidado com a dinâmica hídrica, características da região amazônica. Relatos apontam que no decorrer dos séculos XVII, XVIII e XIX os que chegavam na cidade defrontavam-se com uma superabundância de águas, provenientes de uma área alagada denominada de Alagado do Piry de Jussara. Nesse sentido, o referido estudo buscou, através do geoprocessamento, reconstituir espacialmente a área e a geometria do alagado, bem como espacializar a ocupação urbana sobre o mesmo. Dessa forma, através da elaboração de mapas nos anos de 1631, 1700, 1760, 1791, 1844 e 1905 foi possível identificar que as obras de dessecamento do Piry ocorreram durante todo o século XIX, e que a área que outrora foi ocupada pelo Alagado, hoje abrange três bairros do centro de Belém, os quais sofrem com enchentes e inundações rotineiramente. Assim, ao fim do estudo, questiona-se a forma com que os gestores lidam com a superabundância de água na região, uma vez que foi possível concluir que a cidade de Belém cresceu e expandiu-se sobre as águas, e que até hoje tende a conviver com problemas relacionados ao fator hidrográfico da região.
A contribuição da política ambiental brasileira na proteção das áreas de conservação urbanas
Authors: Silva Guilherme Henrique Pereira da , Branchi Bruna Angela
Published: March 2021

Neste artigo é analisado o papel da política ambiental brasileira, em geral, e do Sistema Nacional de Unidades de Conservação, em particular, com relação à sua contribuição ao desenvolvimento sustentável. O aumento das unidades de conservação criadas no Brasil, especialmente a partir dos anos 2000, poderia ser evidência da importância dada à proteção e conservação do meio ambiente no país. A política ambiental brasileira identifica no plano de manejo um instrumento essencial para a gestão, consolidação, conservação e desenvolvimento da unidade de conservação (UC). Porém através da pesquisa documental realizada foi constatada a ausência de planos de manejo na maioria das unidades de conservação. Além disso, há planos de manejo mal elaborados ou desatualizados que deixam de cumprir seu papel. Em síntese, estes resultados mostram como a legislação brasileira oferece instrumentos para uma boa governança, promotora do desenvolvimento sustentável das UCs. Mas na realidade a legislação carece de efetividade dada a ausência de um monitoramento sistemático da implementação e avaliação do manejo das UCs.
Enemies of the People?
Authors: Rozenberg Joshua
Published: March 2021

Do judges use the power of the state for the good of the nation? Or do they create new laws in line with their personal views? When newspapers reported a court ruling on Brexit, senior judges were shocked to see themselves condemned as enemies of the people. But that did not stop them ruling that an order made by the Queen on the advice of her prime minister was just 'a blank piece of paper'. Joshua Rozenberg, Britain's best-known commentator on the law, asks how judges can maintain public confidence while making hard choices.
Modi and the Reinvention of Indian Foreign Policy
Authors: Hall Ian
Published: March 2021

Narendra Modi's energetic personal diplomacy and promise to make India a 'leading power' surprised many analysts. Most had predicted that his government would concentrate on domestic issues, on the growth and development demanded by Indian voters, and that he lacked necessary experience in international relations. Instead, Modi's first term saw a concerted attempt to reinvent Indian foreign policy by replacing inherited understandings of its place in the world with one drawn largely from Hindu nationalist ideology. Following Modi's re-election in 2019, this book explores the drivers of this reinvention, arguing it arose from a combination of elite conviction and electoral calculation, and the impact it has had on India's international relations.

This book uses up-to-date evidence to interrogate some of the controversial claims made by the 2016 Casey Review, providing an analysis of contemporary patterns of ethnic, residential and social segregation, and looking at the ways that these changing geographies interact with each other.
An EFL Coursebook Evaluation in terms of Design and Language: Private School Samples in Sinop
Authors: YAZICI Yeliz , HAYTA Pelin
Published: March 2021

This study aims to evaluate an English textbook in a private school example in Sinop. Although private schools and public schools follow the same curriculum, there are differences in the textbook preference. In this study, as an external evaluation, the English textbook was examined in terms of the design elements; and, as an internal evaluation, the book was examined in terms of the instructional elements. The research design was qualitative and the process was carried out by two different researchers. Results showed that although the textbook was found appropriate and effective based on the external evaluation: graphic design and print quality; the presentation of the four language skills in the textbook was poor. Reading skill was the most dominant skill presented, and writing skill was the least presented skill in the textbook. Therefore, the textbook needed supportive material to present other skills effectively. It is concluded that the textbook in this study is not suitable for teaching four language skills effectively and is not suitable for the purposes of the English language content as defined by the Ministry of Education.

CHARGE-SYMMETRIC DESCRIPTION OF ELECTRONS AND POSITRONS IN THE DIRAC THEORY WITHOUT NEGATIVE ENERGIES
Authors: Poluektov Yu.M.
Published: March 2021

A formulation of the Dirac theory, symmetric with respect to particles and antiparticles, in which negative energy states are excluded, is proposed. Fields of particles and antiparticles are associated with wave functions for which the Born interpretation as probability amplitudes is valid. Thus, in theory, various ”paradoxes” are eliminated, the existence of which is due to incorrect accounting of states with negative energy.
USE OF THE WHIRLIGIG PRINCIPLE FOR STABILIZING THE INITIAL STATES OF SOME CLASSIC AND QUANTUM SYSTEMS
Authors: Buts V.A.
Published: March 2021

It is shown that the whirligig principle can be used for stabilization of the initial states of some classical and quantum systems. This feature of the whirligig principle is demonstrated by simple examples. The most important result of this work is the proof of the fact that the stabilization of the excited states of quantum systems can be realized by acting not on the quantum system itself, but by acting on the states into which the system must go. Potentially, this result can be used to stabilize excited nuclear systems.

Hernias are common in children and account for most of the surgical operations performed by the Paediatric surgeons. They often present late in resource-poor countries for a variety of reasons. In these settings, surgical outreaches reduce the burden of hernias. We aim to determine the effectiveness of a tertiary hospital-based surgical outreach for hernia repair in children in a low-resource-setting. We did a prospective study conducted during a surgical outreach carried out over seven days at a tertiary center in Southeast Nigeria. Recruited subjects were physically examined to establish a diagnosis and screened for fitness before surgeries were performed. Data were collected using a structured proforma to information from the patient's case-notes. Data analysis was done using the statistical package for social sciences (SPSS) version 25. There were 77 children with 80 hernia surgeries, 71 (92.2%) males, and 6 (7.8%) females (ratio of 12:1) were involved. The majority (66.2%) were aged 2-12years and were mainly rural dwellers. Right groin hernias were present in 54.5% and 40.3% had left groin hernias. Herniotomy was the main procedure offered (93.5%). The complication rate was 9.1%. Senior registrars in surgery (Senior trainee surgeons) participated in most of the operations. The mean duration of surgery was 34.9 + 17.6 minutes. Surgical outreach in tertiary hospital for hernias in children in resource-poor settings offers the opportunity for mass repairs with good outcomes. It provides a hands-on opportunity for trainee surgeons to improve their mastery of hernia surgery.

Published: March 2021

Gelenekler, insan topluluklarını ortak bir paydada buluşturarak toplumu var eden sosyal ritüellerdir. Toplumun en küçük yapı birimi ve kültür aktarıcısı ise ailedir. Bu nedenle Türk kültüründe aile kavramına büyük değer verilmiştir. Ailenin oluşturulması da çevrede yaşan diğer insanlara kız isteme, nişan, nikâh, kına gecesi, gelin çıkma gibi pek çok ritüel ile duyurulmaktadır. Bu ritüeller tüm Türkiye’de yöresel farklılıklar göstermektedir. Düğün ritüellerinin yöresel farklılıklara rağmen en önemli ortak özelliği ise bütün toplumlarda bu ritüellere büyük değer verilmesi ve çeşitli eğlence törenleri ile kutlanmasıdır. Çankırı Kızılırmak’ta da düğün eğlenceleri; geçmişten beri toplumsal değerini kaybetmeden, zamanın şartlarına göre bazı değişiklikler göstererek, uygulanmaya devam etmektedir.
Bu çalışmada Çankırı ili Kızılırmak ilçesinde kına gecesi ve gelin alma törenindeki ritüeller, sahada yapılan derleme çalışmaları sonucunda toplanmıştır. Bu bilgileri, görüşme yaptığımız 14 kaynak kişinin yanı sıra alan çalışmasında elde ettiğimiz 4 eski kaynak video ve fotoğraflar oluşturmaktadır. Kaynak kişiler seçilirken yörede uzun süreden beri ikamet etme, yörenin düğün geleneğini iyi bilme, gelenekleri uzun yıllardan beri şahsen tecrübe etme ve böyle ailelerde yaşamış olma kriterleri esas alınmıştır.
Alan çalışmamızda, kaynak kişilerin evlerine gidilerek önceden hazırlanmış sorular bu kişilere sorulmuş ve cevapları kayda alınmıştır. Derlenen malzemeler hem ses kayıt cihazına kaydedilip hem de yazıya aktarılmıştır. Kaynak kişilerin bazıları seslerinin kaydedileceğini duyunca konuşmaya çekinmiş, seslerinin yayımlanmayacağı ve kayıtların yazıya dökülerek kullanılacağının belirtilmesi üzerine ses kaydı ile bilgi vermeyi kabul etmişlerdir. Çalışmamızın malzemelerini; alınan ses kayıtları, kaynak kişilerin evlerinde bulunan video kayıtları ve fotoğraflar oluşturmaktadır.

La fusión de realidad y ficción en las acciones promocionales no convencionales de Pixar
Authors: Selva-Ruiz David
Published: March 2021

Aunque la promoción de las películas de Pixar emplea herramientas convencionales —cartel, tráiler, etc.—, desarrolla también acciones innovadoras que buscan generar notoriedad y cooperar en la construcción de marca. Estas acciones parecen acentuar una de las metas del cine de Pixar: que los personajes, mundos y narrativas de ficción sean percibidos como reales. Este trabajo tiene como objetivo analizar el juego entre realidad y ficción en el uso de herramientas de comunicación no convencionales para la promoción de las películas de Pixar. Se concluye que su promoción engloba contenidos y acciones no  convencionales de gran originalidad y que contribuyen al universo narrativo de laspelículas y, por tanto, de la propia marca Pixar; y que estos contenidos y acciones, en su diversidad, tienen el nexo común de intentar traer la ficción de las pantallas a una esfera real o incluso física.
