Published: April 2020

L’hétérogénéité durable de la fécondité moderne constitue un défi pour la modélisation démographique en imposant d’étudier les variations entre les nombreuses sous-populations qui constituent la société. Elle impose aussi que les groupes élémentaires soient conçus comme existant à différents niveaux d’organisation sociale (strates socioéconomiques, ethnies, secteurs d’activité, réseaux de parenté et réseaux familiaux…), et que soient spécifiés les modes de relation et les effets de superposition entre ces sous-populations. Les processus réticulaires qui sous-tendent la population et sa structuration sociale aggravent la difficulté car, dans leur fonctionnement normal, ce ne sont pas des groupes de population délimités comme ceux auxquels a d’habitude recours l’analyse quantitative formelle. Ils nécessitent de renouveler l’analyse des compositions démographiques. Les données provenant d’une étude multisite et longitudinale de communautés indonésiennes offrent l’occasion d’explorer comment construire des modèles de variation de la fécondité sur la durée. Le caractère ouvert et mobile des réseaux locaux est décrit à partir de trois types d’apparentement qui se recoupent. L’étude ethnographique et des enquêtes sur échantillons aléatoires permettent, conjointement, d’établir et d’interpréter un modèle de niveaux socioéconomiques qui tienne compte de la flexibilité des réseaux. Ce modèle sert en particulier à identifier certains défauts importants dans plusieurs modèles et indicateurs démographiques usuels. La constatation de différences entre réseaux et entre niveaux montre la diversité sur le temps long de la transition de fécondité en Indonésie et la nécessité de ne pas prendre pour acquise la poursuite des déclins observés.
Spatial diffusion of fertility decline in northern Sweden, 1850-1950
Authors: Junkka Johan
Published: April 2020

Cet article étudie les relations entre les pratiques de fécondité de couples mariés résidant dans un voisinage immédiat, dans le nord de la Suède de 1850 à 1950. Pour cela, il s’appuie sur deux échelles géographiques complémentaires en comparant la fécondité entre des zones géographiques voisines et entre couples voisins à l’intérieur d’une même zone. L’article montre que les couples qui habitent dans des zones géographiques voisines ont une fécondité comparable au début de la transition démographique comme au cours de celle-ci, par contre ce n’est pas le cas avant ou après la transition. L’évolution de la fécondité à long terme est similaire dans des zones géographiques voisines mais c’est l’inverse pour les variations de court terme. Ces résultats suggèrent que la fécondité est affectée par des mécanismes d’interaction sociale à l’intérieur de réseaux de voisinage avec un effet plus important durant la transition démographique.

Published: April 2020

Tout à la fois témoins, acteurs et victimes de la guerre du Liban (1975-1990), les diplomates constituent une catégorie à part entière du conflit. S’appuyant sur des archives diplomatiques françaises inédites récemment ouvertes aux chercheurs, cet article s’intéresse aux ambassadeurs de France à Beyrouth. Il cherche à montrer comment la guerre a pu entraîner pendant près de seize ans une adaptation des pratiques et usages diplomatiques sur le champ de bataille libanais.
Opportunités et défis de la justice transitionnelle au Liban : la centralité de la question des disparus ou Chronique d’une guerre inachevée
Authors: Hassoun Abou Jaoudé Carmen
Published: April 2020

Près de trente années après la fin officielle de la guerre du Liban (1975-1990), et environ quinze ans après le retrait des forces syriennes du Liban (1990-2005), cet article se propose de revenir sur la « sortie de guerre » problématique et inachevée. Dans une perspective de justice transitionnelle, l’étude souligne la centralité de la question des disparus de la guerre dans le traitement des violences politiques au Liban. Elle remet en question les tentatives de réconciliation entre leaders politiques et soutient la nécessité d’un travail de vérité et de mémoire qui inclurait toutes les strates de la société libanaise. Mais les défis qui lui font face sont énormes, notamment la réticence des anciens chefs de guerre à s’engager dans un processus qui pourrait remettre en question leur autorité et leur pouvoir.
A physical mechanism of sensitivity enhancement of organic X-ray detectors with tungsten nanoparticles
Authors: Poškus Andrius , Dobužinskas Rokas , Viliūnas Mindaugas , Arlauskas Kęstutis
Published: April 2020

A simple theoretical model explaining the increase of X-ray sensitivity caused by adding tungsten nanoparticles into thin layers of organic materials is proposed. The mentioned increase of sensitivity is caused by quenched electron multiplication due to secondary electron emission from tungsten particles. After some simplifying assumptions, an expression of the electron multiplication factorKis derived for the case when tungsten atoms are uniformly mixed with the matrix material. The main assumption of the model is the existence of a threshold energyEminof the order of 0.1 eV, below which the recombination of charge carriers prevents them from being accelerated by the electric field to energies sufficient for impact ionization. It is shown that this assumption makes the increase ofKand photocurrent with increasing electric field much slower than the exponential increase commonly associated with an electron avalanche, andKmay even start to decrease when the electric field strength exceeds a certain value. Another factor, which has an adverse effect on the X-ray sensitivity, is the ionization energy loss of photoelectrons inside metallic nanoparticles. The results of Monte Carlo simulations show that in the case of spherical tungsten particles with 0.8 μm diameter, the latter phenomenon may cause an additional decrease of the sensitivity by as much as 75%. In order to reduce this effect, the size of nanoparticles should be reduced, or, alternatively, most of the photoelectrons should be generated in the organic matrix rather than inside the nanoparticles.
Quantum paraelectricity and induced ferroelectricity by germanium doping of (PbySn1–y)2P2S(Se)6 single crystals
Authors: Zamaraitė Ilona , Džiaugys Andrius , Vysochanskii Yulian , Banys Jūras
Published: April 2020

In this paper we report a dielectric study on four single crystals Pb2P2S6, (Pb0.98Ge0.02)2P2S6, (Pb0.7Sn0.3)2P2S6 + 5% Ge and (Pb0.7Sn0.3)2P2Se6 + 5% Ge down to 20 K. A new quantum paraelectric state was reported in the Ge-doped samples at low temperatures. In all of these materials the non-classical T2 temperature dependences of inverse dielectric permittivity were observed. The dielectric constants of Pb2P2S6-based single crystals were measured between 20 and 300 K. The temperature dependences of dielectric permittivity were analysed on the basis of Barrett’s model as a signature of quantum paraelectricity.
Les capitales des cités gauloises, simulacra Romae ?
Authors: Reddé Michel
Published: April 2020

La conception classique de la ville méditerranéenne, modèle urbanistique des nouvelles capitales de cités fondées par Rome dans les provinces après la conquête, répond-elle à une réalité archéologique ou à un « Idealtyp » ? L’enquête archéologique qui est ici présentée montre qu’en Gaule Chevelue tout au moins, l’émergence des nouveaux chefs-lieux ne répond pas à un phénomène univoque et que plusieurs facteurs ont joué un rôle déterminant dans ce processus : l’héritage protohistorique, qu’il convient de réévaluer fortement par rapport à notre vision traditionnelle, la dynamique propre au développement urbain antérieur à la conquête, la place des grands sanctuaires laténiens, l’implantation du nouveau réseau viaire, qui a modifié les équilibres géographiques et économiques antérieurs, l’implication des élites locales, leur degré d’insertion dans les nouveaux cadres politiques romains et leur richesse qui conditionne leur capacité d’évergétisme. Bien entendu, les différences régionales peuvent être très marquées et la fondation ex nihilo d’une capitale provinciale conçue dès l’origine comme telle (Cologne) ne saurait être comparée à celle d’une cité pérégrine comme Le Mans. Le processus chronologique semble lui-même assez lent et progressif, même dans le cas de villes nouvelles comme Amiens ou Autun, passant souvent par plusieurs étapes successives. Sauf exception notable, la majorité des capitales de la Gaule Chevelue ne semble guère apparaître ou connaître de transformations substantielles avant la dernière décennie antérieure à l’ère chrétienne, parfois sensiblement plus tard, et le processus d’urbanisation dure souvent jusqu’au milieu du i er s. apr. J.-C. au moins, parfois jusqu’à l’époque flavienne.
Angers/Iuliomagus, cité des Andécaves, et Le Mans/Vindinum, cité des Cénomans : deux capitales, deux modes de déploiement urbain
Authors: Chevet Pierre , Pithon Martin
Published: April 2020

Iuliomagus et Vindinum, capitales de cités voisines, connaissent un développement urbain qui se différencie au premier chef dans ses dynamiques de mise en œuvre, mettant ainsi en évidence des modalités d’aménagement distinctes. Alors que la première connaît, dès les années 20 apr. J.-C., une restructuration urbaine d’ampleur inscrite au sein d’une trame viaire orthogonale de 90 ha, mise en place en 10 ans et totalement affranchie des contraintes topographiques, la seconde montre un déploiement plus lent, avec une mise en place des rues étalée entre 30 et 60-70 apr. J.-C., une adaptation à la topographie et des programmes de remodelage du relief qui perdurent durant tout le ier s. au moins. Ces modes d’évolution opposés engendrent des paysages urbains très différents. Le site angevin, qui procède d’un plan global, anticipé et rapidement mis en œuvre, présente un urbanisme de façade, en apparence rigide et uniforme, mais qui conserve, en cœur d’îlots et en périphérie, les lignes des organisations anciennes. En revanche, Le Mans, qui semble s’étendre et évoluer sans stratégie d’ensemble, connaît une transformation plus progressive qui semble s’exercer en profondeur et effacer toute trace du paysage urbain antérieur.La question des causes qui ont pu déterminer des développements urbains si divergents reste ouverte. À titre d’hypothèse, c’est un soutien affiché ou une pression appuyée de l’administration romaine centrale, qui aurait pu favoriser ou imposer une telle restructuration à Angers. Quelles qu’en aient été les motivations militaires ou politiques, de telles raisons n’ont vraisemblablement pas eu cours au Mans, où des nécessités plus locales, démographiques et économiques, ont sans doute prévalu.

Les fouilles réalisées à Chartres ces dix dernières années, systématiquement mises en séquences et datées par l’étude de la céramique, fournissent un corpus de sites de référence pour l’établissement des grandes phases marquant l’évolution de la ville durant le ier s. apr. J.-C. Parmi ceux-ci, deux nécropoles précèdent l’installation de la ville romaine. Son réseau viaire et les bâtiments qui le bordent constituent un bon marqueur des rythmes de son développement. Les constructions publiques sont probablement édifiées à partir du milieu du ier s. apr. J.-C. La datation du creusement du grand fossé à talus a longtemps posé question. Il semble devoir être rattaché au ier s. apr. J.-C.
Metz/Divodurum, cité des Médiomatriques : apport de deux fouilles récentes (place de la République et rue Paille-Maille) à la question des origines
Authors: Brkojewitsch Gaël , Dreier Christian , Marquié Sandrine
Published: April 2020

L’objectif de cet article est de donner un état des connaissances sur les origines de la ville romaine de Metz/Divodurum. Pour y parvenir, les sources littéraires et le résultat des fouilles archéologiques urbaines sont employés. Les principales recherches dans le noyau urbain seront décrites en suivant une logique chronologique et topographique (colline du Haut de Sainte-Croix, colline de la Citadelle, secteur Outre-Seille, Pontiffroy). Le postulat étant que la ville romaine se développe à l’emplacement de l’oppidum (colline du Haut de Sainte-Croix) quasiment sans interruption depuis l’occupation laténienne, l’attention a été portée sur deux quartiers qui ont fait l’objet de fouilles récentes (place de la République, fouillée en 2009 sur la colline de la Citadelle et rue Paille-Maille, fouillée en 2012 dans le quartier du Pontiffroy) afin d’offrir des éléments de comparaison. Les données recueillies permettent d’illustrer les formes de l’habitat et d’évoquer le développement urbain et les limites de ville après la Conquête.
Anthropologie et diplomatie
Authors: Vienne Emmanuel de , Nahum-Claudel Chloé
Published: April 2020

Secouée par les populismes, le bouleversement des équilibres entre les grandes puissances, la révolution numérique, la crise planétaire et la défiance envers des institutions de gouvernance mondiale conçues dans une période moins désespérée, la diplomatie traverse une crise profonde. Loin d’apporter une solution idéaliste de plus, cette introduction esquisse une théorisation ancrée dans la comparaison de cas empiriques qui sortent de la définition classique de la diplomatie centrée sur les rapports entre États. En privilégiant une approche pragmatique et interactionniste, et en étant attentive aux inventions des vaincus, elle entend identifier quelques traits constitutifs de la situation diplomatique : un rapport particulier à la violence (qui n’est pas toujours d’exclusion), l’invention de rituels qui sont autant de modélisations du monde, l’imitation de l’autre au risque de la confusion.

A competência motora (CM) é um atributo associado a comportamentos positivos de saúde; fatores contextuais, parecem desempenhar um papel importante para CM de crianças. O objetivo deste estudo foi comparar a CM de pré-escolares em dois diferentes anos e identificar o efeito de fatores contextuais (tipo de escola e renda). Duas amostras representativas de crianças (3 a 5 anos) da cidade do Recife foram avaliadas em dois momentos: no ano de 2010 (282 crianças; 151 meninos) e 2012 (270 crianças; 148 meninos). A avaliação da CM foi realizada com o Test of Gross Motor Development – 2. A análise dos dados utilizou a Anova Two-Way e a Ancova ajustada por tipo de escola (pública e particular) e renda familiar, foi adotado um p<0.05. Foi identificada uma superioridade nas habilidades locomotoras, de controle de objetos e no quociente motor geral para as crianças analisadas em 2010 e o tipo de escola e renda aumentaram o tamanho do efeito das diferenças nas habilidades de controle de objetos e no quociente motor geral. Podemos concluir que houve uma diminuição na CM da população pré-escolar após dois anos e que as variáveis contextuais tipo de escola e renda são importantes para o desenvolvimento da CM.
Characteristics of learning and training of elite athletics in Brazil: the perspective of experienced coaches
Authors: Caregnato André Felipe , Ordonhes Mayara Torres , Silva Marcelo Moraes , Cavichiolli Fernando Renato
Published: April 2020

The present study sought to verify the perspective of the coaches regarding the teaching, learning and training process in Brazilian Athletics. Semi-structured interviews were applied to six Brazilian athletics coaches with participation in the Olympic Games. From the interviews, two categories were defined: formation and development of athletes; talent and long-term training. About the age indicated to start in athletics, the coaches reported that the ideal (f = 56.90%) is that the athlete starts in the sport in the youth. However, they chose not to stipulate a single age group to start in the sport. Characteristics that induce the organization of a work model in athletics (f= 26.14%) were frequent in the speeches. There was a lack of specific parameters on how the profession of coaching should be exercised - in this case athletics - it is necessary to have structures that enable the development of the coach’s career.

Published: April 2020

This study aimed to evaluate the implementation of an intervention program to promote active and healthy lifestyle in students. This was a evaluation study performed during the intervention, which included the school community (students, teachers, coordinators and parents), through interview or external observation. The evaluation matrix was constructed and validated with 32 measures in eight indicators: teacher training, modification in Physical Education classes, modification in regular classes, distribution of pamphlets, distribution of material, gymnastics in the school, visibility of the program and knowledge and distribution of material. Descriptive (quantitative) or content (qualitative) analysis was used. Health issues in the classroom were addressed by 94% of teachers during the intervention. Half of the students reported that they participated in at least one gym class and used the games during the intervention, but difficulties in storage of sports equipments and organization of places were reported. Knowledge about the program was frequent among teachers, managers and students, but not between parents. In conclusion, most of the program actions had an implementation as planned, however, difficulties were reported and should be considered in future proposals of a school environment that aims to promote physical activity and health.

Published: April 2020

The objective of this study was to verify the association of psychological factors and body practices with the academic performance of high school students. A sample of 330 students participated, made up of 167 girls and 163 boys. Likert scale instruments were used for collecting information on self-concept, and on general and academic self-efficacy. Time spent on moderate to vigorous physical activity was recorded, and so was participation in several types of body practices, such as sports, dances, martial arts, performing arts, and systematic physical exercises. Academic achievement was referred to from the students' grades on regular subjects. Linear regression analysis was used for verifying the association of independent variables with academic performance. The adjusted regression model explains between 7% and 36% of academic performance variance, whereas Self-Concept explains academic performance on six of the twelve subjects, and the mean of the grades, with Beta values between 0.13 (p = 0.02) for Sociology and 0.28 (p <0.01) for Mathematics. Academic self-efficacy explained performance on eleven subjects and the mean of the grades, with Beta values between 0.21 (p <0.01) for Physical Education and Philosophy, and 0.44 (p <0.01) for Biology. Participation in extracurricular activities involving body practices explained academic performance on six subjects and the mean of the grades, with Beta values between 0.14 (p = 0.02) for Sociology and 0.31 (p <0.01) for Arts. The studied psychological variables and participation in projects concerning body practices during extracurricular activities correlated with academic achievement as to several school subjects, and with the mean of the grades.

O objetivo desta pesquisa foi analisar o gerenciamento dos Resíduos Sólidos de Serviço de Saúde (RSS) gerados em domicílio e encaminhados a estabelecimentos públicos de saúde do município de Umuarama – PR. A coleta de dados foi dada por meio de um formulário em entrevista com os responsáveis das unidades que detém o maior conhecimento no gerenciamento dos RSS. Os resultados revelaram que os pacientes encaminharam às unidades pesquisadas RSS do grupo A (gazes, sondas, luvas, tiras reagentes), B (medicamentos) e E (agulhas com seringas acopladas, lancetas e ampolas). Os medicamentos e perfurocortantes foram os RSS que obtiveram uma maior frequência de descarte. Quanto aos recipientes utilizados como acondicionamento, verificou-se a presença de diversos tipos como: sacos plásticos, garrafas PET, potes de sorvete, caixas de sapato, frascos de azeitona/maionese/álcool, e caixas de isopor. Notou-se a ausência de postos e recipientes de coletas, profissionais específicos no manejo, recipientes de transporte interno e local para o armazenamento externo dos resíduos. Os resultados obtidos neste estudo permitem concluir que muitos pacientes possuem a consciência de descartar corretamente os RSS que geram em domicílio. Portanto, cabe aos estabelecimentos de saúde estarem equipados para receber os RSS domiciliares e garantir que estes materiais tenham um manejo adequado, seguro e uma disposição final correta conforme preconizado pela legislação vigente.

Nas análises de cinzas, proteínas e lipídeos seus valores não sofreram alteração em relação o tempo de armazenamento, apresentando pequenas variações durante o tempo e estocagem que podem ser devido a reações químicas. Os cookies apresentaram durante o período de 60 dias condições físicas e físico-químicas desejáveis, assim, pode-se afirmar que a embalagem laminada, tanto para os cookies com gergelim quanto para com amendoim, se destacou.
CONCRETO AUTOADENSÁVEL COM BAIXO CONSUMO DE CIMENTO COM ADIÇÃO DE RESÍDUO DE POLIDORA CERÂMICA
Authors: Da Silva Barboza Lucas , Freitas André , Freitas Andrey , Rodrigues Danilo
Published: April 2020

O Concreto Autoadensável (CAA) deve apresentar alta fluidez, resistência à segregação e habilidade de passagem. Entretanto, para se atingir tais características é necessário maior consumo de aglomerante e adições, gerando um custo maior na fabricação do concreto. Na tentativa de contribuir com a redução do custo de fabricação, utilização de recursos naturais e diminuir os impactos ambientais, o presente trabalho tem como objetivo analisar as propriedades no estado fresco e endurecido do Concreto Autoadensável com Baixo Consumo de Cimento (CAABCC) com adição de resíduo de polidora de cerâmica. Para os métodos de ensaio, foram analisados 3 tipos de dosagens, sendo elas de 32%, 33% e 40% do volume de pasta, respectivamente. Os concretos estudados apresentam consumo de cimento entre 434 e 347 kg/m³, apresentando uma redução de até 25% do consumo de cimento em relação ao concreto de referência. As propriedades mecânicas analisadas foram: resistência à compressão axial, resistência à tração por compressão diametral e módulo de elasticidade dinâmico nas idades de 3, 7, 28 e 91 dias. Para os ensaios no estado fresco, foram realizados os ensaios: slump-flow test, funil-V e caixa L, em que apresentou resultados que atentem a ABNT NBR 15823:2017. Constatou-se que, independentemente das porcentagens de resíduo de polidora cerâmica incorporada, houve uma melhoria nas propriedades mecânicas do concreto, mesmo com a redução do consumo de cimento. Tendo em vista que o CAABCC com adição de resíduo de polidora cerâmica apresentou resultados satisfatórios e reduzido consumo de cimento, conclui-se que o CAA é mais vantajoso, pois reduz o custo e os impactos ambientais sem comprometer as suas propriedades.
Evaluation of the Effect of Cooling Conditions and Heat Transfer Coefficients on Solidification of Al-Cu Binary Alloy in Static Casting Process
Authors: Egole Chijioke Peter , Mgbemere Henry E. , Sobamowo Gbeminiyi M. , Lawal Ganiyu I.
Published: April 2020

Source-based method for modelling solidification problems have been modified and presented in the current work. It coupled the effect of thermal radiation to macro-transport codes and was solved using finite volume method. The problem was formulated based on the classic continuum energy conservation equation for transient conduction controlled solidification system. Radiation heat transfer and latent heat evolution were added as source terms and solved with appropriate numerical treatments to obtain a system of linearized source terms. This circumvented the need for the application of any analytical solution to the intricate heat transfer regimes included in the model. The effect of cooling was carried out under various cooling conditions imposed on different surfaces of the mould for the solidifying metal. The resultant influence of cooling on the solid fraction evolution during static casting was then evaluated. The simulated cooling curves show that thermal radiation have no influence on the rate of heat extraction and the results show that the predicted cooling curves and solid fraction updates are similar to the results of previous models. The predicted curves at the top section of the open mould however show a little deviation due to effect of surface tension gradient forces. It was further revealed that heat transfer coefficients has more effect cooling curves and temperature contours at the lateral mould surfaces than the interior of the casting which is in agreement with theory of Newtonian cooling.
Structural Design of an Auto Panel Die Component Based on the Contact Pressure Using Topology Optimization
Authors: Koşar Fatih , Yaman Kemal
Published: April 2020

The main motivation in stamping die industry and academia is panel quality and formability issues rather than the weight and cost of the die. A product should be designed according to the loads that it can be faced in service condition. But somehow this rule is not valid for stamping die design since the minimum distance between the ribs is based on the standards and location and pattern of the ribs which are depending primarily on the company experience. In this work, an auto panel drawing die design is investigated numerically whether it is overdesigned or not. The loads on the die surfaces are calculated by numerical methods. When a panel is drawn between upper and lower die, the contact pressure (CP) occurs on the interface surfaces due to this interaction. Since CP is a vital parameter and it is almost impossible to measure it by experimental methods, it is validated by two different numerical codes. The CP values obtained from Autoform® quasi-static solution are compared with Abaqus® transient forming analysis solution. Topology optimization is applied on the lower die by using the estimated CP loads. Von-Mises stress, elastic deformation and volume are compared between current and optimized die geometry. Panel thickness variation is also investigated in longitudinal and transverse directions.

The Real Winners in Aid for Trade: An Economic Analysis
Authors: Barham Timothy Wolf
Published: April 2020

Over the past two decades, hundreds of billions of dollars have been spent on official development assistance programs to assist developing countries around the world through the Aid for Trade (AfT) initiative. Although the goal of the AfT initiative is to reduce global poverty levels, there is limited evidence that AfT actually reduces poverty. While positive economic growth linked to AfT programs can be seen in both developed and developing countries, developed countries do not experience the same downfalls of international trade as the least developed countries. This article reviews existing research on the AfT initiative, the winners and losers of such agreements, and the potential policy vehicles that can be used by participating governments and organizations to mitigate the unintended effects of AfT.
An Analysis of the Early and Periodic Screening, Diagnostic, and Treatment Benefit: Implications for the Healthcare of Children in Foster Care
Authors: Ferdinand Jae-Marie
Published: April 2020

The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit mandates full coverage of healthcare for children enrolled in Medicaid. The EPSDT benefit provides the access, framework, resources, and financing for healthcare for children with complex healthcare needs. When fully implemented, the EPSDT benefit leads to improved health outcomes. This paper examines the EPSDT benefit as an essential healthcare resource for vulnerable children, notably children in foster care. The majority of children in foster care receive Medicaid healthcare coverage and have complex healthcare needs. According to the most recent research, many children in foster care are not receiving this mandated benefit. Improved implementation of the EPSDT benefit is key to improving health outcomes. This policy analysis reviews the EPSDT benefit, evidence for its effectiveness, issues challenging full implementation for children in foster care, examples of successful implementation, and provides recommendations for improved implementation. Specific recommendations include coordination of healthcare and child welfare services (e.g. with health services coordinators), increased accountability for implementers, and adequate numbers of qualified, trauma-informed providers.

Sarcoidosis is a systemic disease of unknown origin. We describe a case of sputum smear-and culture-negative tuberculosis that was diagnosed with histological examination of a surgical lung biopsy, as other entities such as sarcoidosis could not be excluded after extended investigation. Even a typical lambda sign on gallium scintigraphy proved to be misleading

Poly-ether-ether-ketone (PEEK) cages have lower modulus of elasticity when compared with Titanium (TTN) cages. This suggests that PEEK-cages could show a lower rate of subsidence after anterior cervical discectomy-fusion (ACDF) and might lead to a lower loss of correction. We investigated the one to five year-results of standalone PEEK-TTN-porous coated cages in a patient cohort from 2014 to 2017. The patients underwent single-level ACDF for disc herniation and degenerative discopathy. Clinical and radiological outcome were assessed in 50 eligible patients after a mean of 27 months. Results: Solid arthrodesis was found in 84%. Neck disability index (NDI), and visual analogue scale (VAS) of neck and arm show comparable results to the literature. Conclusions: Clinical and radiological outcomes of ACDF with PEEK-body-cages with a porous coated surface show good bony integration. The modulus of elasticity, design, shape, size, cage surface architecture, as well as bone density, endplate preparation, radical microdiscectomy and distraction during surgery should be considered as important factors influencing the clinical results. One main advantage, over titanium cages, is the absence of MRI artifacts, allowing an excellent postoperative follow-up.

Published: April 2020

The main objective of this study was to evaluate the difference in pain levels during postoperative physical therapy pathways in patients who underwent a cement less total hip replacement either through a muscle sparing direct anterior approach (DAA), or the classic trans-gluteal lateral approach (LA). One hundred and twelve (112) patients were randomized into two equal groups. Baseline values of myoglobin levels were acquired prior to surgery and repeated at 6 hours postoperatively as a biomarker for muscle damage. Pain levels during the first passive and consecutive 3 active physical therapy sessions were noted using a visual analogue-numeric scale (VAS). Pain levels were also acquired at 6 weeks, 3 months, 6 months and 1 year, following a 20-meter (65.6 feet) walking test. Postoperative myoglobin (ng/mL) levels were significantly higher (p< 0.05) in the LA group (335.05±83.54) then the DAA group (237.71±57.54). Pain levels were significantly lower (p<0.001) in the DAA group for both passive (2.5±1.45 vs. 4.28±2.19) and active physical therapy sessions and there was a positive correlation between postoperative myoglobin levels and pain levels until 6 postoperative weeks. There was no significant difference in demographics between the two groups except for gender distribution. The direct anterior approach’s main advantage of being a minimally invasive muscle sparing technique is showing a better rehabilitation experience with lower pain levels during passive and active physical therapy when compared to the classic trans-gluteal lateral approach.

Published: April 2020

Surgery of the foot constitutes a substantial portion of orthopedic procedures, performed by both orthopedic surgeons and doctors of podiatric medicine. Little research exists on the medicolegal implications of foot surgery amongst these specialties. This study seeks to investigate the different medical and legal factors associated with foot surgery-based malpractice litigation. Malpractice data between 2004 and 2017 was collected using the VerdictSearch legal database. Cases involving foot surgery were identified, and case information including physician specialty, procedure, medical outcome, verdict, and payment amount were obtained. A total of 72 cases were analyzed. A majority of lawsuits involved podiatrists (76.4%), with orthopedic surgeons accounting for 15.3%. Lawsuits against podiatrists primarily occurred over elective procedures (94.5%) and most frequently involved plaintiff complaints of persistent pain (41.8%) or deformation (27.3%). Podiatrist cases most often involved allegations of failure to treat (45.5%) or inappropriate surgical procedure (27.3%). Orthopedic surgeons saw higher rates of urgent cases (45.5%), with surgical complications (27.3%) occurring at higher rates than podiatrists. Despite different trends in case types, similar rates of plaintiff victories, and mean payments were seen between podiatrists (25.5%, $911,884 ± 1,145,345) and orthopedic surgeons (27.3%, $975,555 ± 448,795). This investigation is the first to analyze malpractice trends amongst podiatrists and orthopedic surgeons. Differing factors related to medical and legal outcomes can suggest quality improvement targets for both specialties. This data may assist in reducing malpractice risk and refining patient care, particularly with regards to outlining risks, benefits, and alternatives during pre-operative counselling.

Published: April 2020

Hematopoietic stem cell transplantation (HSCT) is now an established treatment modality with definitive indications for many hematological disorders. However, this line of treatment requires tremendous resources, and it becomes increasingly difficult for transplanters  practicing in the developing world to reconcile the difference between what is possible and what is available. On the basis of 30 years of experience and more than 4250 transplants , this article will focus on the challenges faced our HSCT program and how they were solved. The HSCT program in Egypt started in 1989 on a narrow scale and since that time we faced many challenges.In 1997, the transplant rate increased dramatically with the opening of  many HSCT units distributed allover Egypt. Our team is registered in the Center for International Blood and Marrow Transplant Research ,and the number of transplants performed till December 2019 exceeded 4000 cases (60% allogeneic and 40% autologous).

We report the results of a stream sediment and water study that was carried out as part of the GEM2 Western Arctic Region Project's HALIP activity in Canada's Arctic Islands. The survey was complementary to bedrock mapping in three areas of central Axel Heiberg
Island, Nunavut. The objective of the study was to use regional drainage sediment and water to evaluate the mineral potential in these areas. This activity was part of a larger project, undertaken to evaluate mineral potential of the High Arctic Large Igneous Province (HALIP). It also expanded the
drainage coverage from the original study conducted in 2013 in the East Fiord area of western Axel Heiberg Island that provided promising results.
Stream silt and water samples were collected from 72 sites. At 32 of these sites, bulk sediment samples were collected for the heavy mineral concentrate (HMC) component in the <2 mm fraction. Silt and water samples were analysed by ICP-MS and ICP-ES as well as for carbon content. Water
samples were also submitted for alkalinity, anions by ion-chromatography and in situ physico-chemical measurements. Bulk sediment samples were processed and the resulting HMC samples were picked for indicator minerals of various deposit types. Sampling and analytical techniques followed established
NGR methodologies, ensuring data compatibility with the NGR database. Although limited in scope, the study yielded a second drainage dataset for the northernmost part of Nunavut.
Stream sediment surveys carried out in the Lightfoot River and Geodetic Hills areas of Axel Heiberg Island do not show any clear evidence of mineralization. The most promising geochemical and mineral data resulted from a survey in the Expedition Fiord area. We highlight some of the results in a
pilot mineralogical study of the Heavy Mineral Concentrates (HMC) using the MLA-SEM technique. A comparison of data for the East Fiord (2013) and Expedition Fiord (2015) areas highlights the presence of sulphides in the HMCs as well as other similarities in the geological setting. Notable
differences in water, silt and HMC composition between the two areas are not well understood, and require further research on (1) the age, composition and volume of mafic intrusions in the two areas; (2) the extent of mechanical mixing between igneous and evaporite rocks in proximity to diapirs; (3)
compositional variations in streams with distance from glaciers; and (4) the role of conduits for fluid flow in the wall-and-basin evaporite structures in the Strand Fiord-Expedition Fiord area.

Erythema multiforme in two horses
Authors: Marshall Claire
Published: April 2020

Erythema multiforme is reported for the first time in 2 South African horses. Both horses displayed a sudden, fulminant outbreak of raised, non-alopecic and non-pruritic plaques over the dorsolateral aspects of the neck and trunk. In both cases the distribution of the lesions was bilaterally symmetrical. Histopathological findings included hydropic degeneration of basal epidermal cells, eosinophilic necrosis of individual or groups of keratinocytes, intra-epidermal and sub-epidermal cleft formation and mixed, dermal, perivascular infiltrates. An initiating cause could not be identified in either case, Both horses underwent gradual spontaneous remission within 3 months.
A Neuro Fuzzy Classifier with Linguistic Hedges for Speech Recognition
Authors: H Y Vani , M A Anusuya
Published: April 2020

Fuzzy classification is the task of partitioning a feature space into fuzzy classes. A Neuro fuzzy classifier with linguistic hedges is proposed for noisy and clean speech classification. The linguistic Hedges are used to improve the meaning of fuzzy rules up to secondary level. Fuzzy entropy is applied to select optimal features of MFCC for framing the rules for designing the fuzzy inference system. Results obtained from the proposed classifier is compared over conventional and Neuro Fuzzy Classifier. The classification rates of the proposed model is better than other traditional and conventional fuzzy classifiers. 0.22 to 5% improved classification accuracy is observed for the FSDD dataset. And 5% to 11% of improved classification accuracy is observed for Kannada dataset. From this study it is identified that LH plays a major role in classifying the overlapped classes of data.
Impact of Pharmacist Interventions in an Ambulatory Geriatric Care Clinic: The IMPACC Study
Authors: Nguyen Patrick Viet-Quoc , Martínez Andrea Vázquez
Published: April 2020

OBJECTIVE: To compare the impact of a pharmacist's presence for the detection of drug-related problems (DRP) in an interdisciplinary geriatric-ambulatory clinic with a control group without a pharmacist.
 DESIGN: Retrospective quasi-experimental study.
 SETTING:
A geriatric ambulatory-care clinic of a 772-bed tertiary-care teaching hospital in Montreal, Canada.
 PARTICIPANTS: A total of 227 ambulatory patients 65 years of age and older presenting to their appointment at the geriatric ambulatory clinic between May 1, 2018, and April 30, 2019.

MAIN OUTCOME MEASURE(S): DRP detected by the interdisciplinary team during the patient evaluation process. Data were collected from clinical notes written by the health care professionals in the electronic medical chart.
 RESULTS: The mean age was 80.8 years, and 60.8% of the population
were female. Patients were prescribed a mean of 11.3 medications at home. Overall, 636 DRP were detected in the study population. In the adjusted analysis, the difference between the two groups was 2.7 (95% confidence interval 2.0-3.3) DRP detected favoring the group with a pharmacist.

CONCLUSION: The inclusion of a pharmacist in an interdisciplinary team in an ambulatory geriatric-care clinic was associated to a positive impact on care by substantially increasing the number of DRP detected in older patients.
