Authors: Ordoñez Roberth , Gaitán Luisa Fernanda , Burbano Lina Daiana , Buesaquillo Camayo Christian Ali , Calvache España Jose Andrés
Published: April 2021

Antecedentes: El cáncer es una causa importante de morbimortalidad en el país. Los registros hospitalarios de cáncer brindan información importante sobre el comportamiento de las neoplasias malignas atendidas en una institución.Objetivo: describir las características sociodemográficas y clínicas de pacientes menores de 18 años con sospecha o diagnóstico de cáncer, atendidos en el Hospital Universitario San José de Popayán en un periodo de 4 años (2013 al 2017).Métodos: Estudio observacional basado en datos rutinarios relacionados con el diagnóstico de cáncer. Se incluyeron todos los pacientes menores de 18 años de edad, a quienes en la epicrisis hospitalaria se les registró al menos un diagnóstico de las categorías C y D (Neoplasias C00 hasta D048) del manual CIE10. Se aplicó a cada historia un instrumento que incluía variables sociodemográficas, clínicas y de seguimiento.Resultados: De 450 registros iniciales se excluyeron 359 (86%) y se seleccionaron 56 pacientes. Las neoplasias más frecuentes en esta población fueron las hematológicas con un 42% y la cefalea fue el motivo de consulta más frecuente (23%). La mayoría de los pacientes provienen del área rural (68%) y tienen el régimen subsidiado como sistema de afiliación en salud (79%). El 82% de los pacientes fue remitido a otras instituciones y la mayoría de los pacientes atendidos en el hospital, correspondió a pacientes con tumores del sistema nervioso central.Conclusiones: La población pediátrica que se atiende en el HUSJ con sospecha o diagnóstico de cáncer es escasa y, en su gran mayoría, los pacientes son remitidos a otras instituciones de salud.
Impacto oculto de la pandemia por SARS-CoV-2, un reto en pediatría
Authors: Parra García Janneth Consuelo , Roldán Tique Paola Andrea , Torres Nossa María Paula
Published: April 2021

Introducción: El impacto de la pandemia por COVID 19 se ve reflejado en la economía, los sistemas de salud, la educación, la violencia intrafamiliar y la salud mental, entre otros. Como consecuencia se afectarán las poblaciones más vulnerables, entre ellos la población pediátrica y en especial a los menores de 5 años. Objetivo: conocer algunos determinantes sociales de la salud que se veían alterados desde antes de la pandemia y como se han visto afectados por la actual situación de salud pública. Métodos: revisión bibliográfica de tipo narrativo. Se realizó una revisión de la literatura a través de PubMed y directamente en buscadores como Google y Safari donde se obtuvo información de organizaciones internacionales en el periodo 2016-2020. Resultados: se seleccionaron 31 artículos de organizaciones internacionales que evalúan el impacto que ha tenido la pandemia por COVID-19 en la población pediátrica. Conclusiones: la pandemia por COVID-19 afecta a la población pediátrica con consecuencias directas en los determinantes sociales en salud y plantea nuevos retos en pediatría más allá de la morbimortalidad de la enfermedad. Se necesita un cuidado interdisciplinario globalizado para impactar de manera positiva sobre la salud física y mental, la educación y la prevención de la violencia, contribuyendo al desarrollo integral en esta población.
La communication des consciences et les relations avec autrui
Authors: Henry Michel
Published: April 2021

Rédigées entre 1943 et 1953, ces notes inédites révèlent combien Michel Henry fut préoccupé par le problème de « l’expérience d’autrui » dès ses années de formation philosophique. Elles révèlent également l’utilisation précoce d’une jeune Henry des Ecritures comme source d’inspiration pour un certain nombre d’intuitions spécifiquement philosophiques qu’il développera dans sa trilogie de fin de vie sur la philosophie du christianisme.
La fécondité de la phénoménologie de la vie de Michel Henry pour les approches en deuxième personne.
Authors: Depraz Nathalie , Mauriac Frédéric
Published: April 2021

Les recherches de Natalie Depraz sur l’intersubjectivité rejoignent ici celles de Frédéric Mauriac, particulièrement dans les cas dits « d’urgence psychiatrique ». La question est ainsi de savoir comment poser et penser le rapport fulgurant de la force vitale à ce désir tout humain de vouloir en finir. En ces cas, quelles paroles faut-il oser et quel mode de relation convient-il d’instaurer ? La contribution entend offrir des perspectives théoriques et pratiques, essentiellement thérapeutiques, en mettant d’abord en évidence, d’une part, la situation de la phénoménologie henryenne devant la phénoménologie historique et, d’autre part, sa situation devant une praxis fondée sur la singularité de l’approche en deuxième personne.
Michel Henry lecteur de Claude Tresmontant : création, révélation, écritures.
Authors: Hernandez-Dispaux Joaquim
Published: April 2021

Joaquim Hernandez-Dispaux propose une étude qui est le fruit d’un long contact avec les notes préparatoires ayant servi à la rédaction de la trilogie sur le christianisme de Michel Henry, où il révèle l’influence latente de Cl. Tresmontant dans la compréhension henryenne du milieu johannique. Ce n’est toutefois pas tant le parangon de la « philosophie chrétienne » qui retient M. Henry, mais ses recherches autour d’un Christ hébreu, essentiellement utilisées pour fonder une sorte d’archéologie christologique permettant de remonter vers la parole la plus originaire. Par cette médiation inattendue, on voit combien M. Henry recherche à la fois la fondation transcendantale de la parole christique dans son authenticité la plus originaire, mais aussi sa radicale différence par rapport aux mondes grec et juif, celui-ci voyant passer le point de rupture par rapport à la question de l’immanence.
Archi-intelligibilité johannique dans la phénoménologie de Michel Henry
Authors: Kühn Rolf
Published: April 2021

R. Kühn rappelle dans cette étude quelques principes sur les prérequis phénoménologiques de l’analyse spécifique du Prologue de Jean, lu au prisme d’une méditation attentive de Maître Eckhart. Il est évident que M. Henry se situe parmi les grands interprètes de ce texte qui influença les plus hautes spéculations en philosophie de la religion. Dans l’étude de cette profonde affinité entre M. Henry et l’Évangile de Jean, R. Kühn met en évidence l’analyse phénoménologique de la liaison entre l’homme et Dieu, pensée dans le cadre d’une éthique et d’une théorie de la vérité affective. Si M. Henry peut ainsi préciser le geste de l’épochè de toute généalogie mondaine, en posant le premier Fils de Dieu au « commencement », et ceci en un rapport d’irréversibilité, il apparaît qu’il pense ainsi davantage la rupture du geste transcendantal que sa différence ou sa distance, puisque la naissance et la vie sont en deçà du monde et dans « l’intériorité de l’expérience transcendantale ».

Phénoménologie de l’Incarnation
Authors: Henry Michel
Published: April 2021

Cet article présente un texte inédit de Michel Henry préparatoire à son ouvrage « Incarnation ». Il donne de précieux aperçus sur la manière dont Henry concevait l’articulation – profondément nouvelle dans son œuvre – des problématiques de la chair et de l’incarnation et souligne explicitement les enjeux indissociablement éthiques et sotériologiques.
La réception ambivalente de Fichte dans L’essence de la manifestation
Authors: Hattori Yukihiro
Published: April 2021

La référence à Fichte traverse de manière discrète mais non moins fondamentale L’essence de la manifestation, où de nombreuses pages sont consacrées à l’Anweisung — texte avec lequel la pensée henryenne partage explicitement le schéma « dualiste », mais également de manière implicite une même définition de l’être. Ce schéma, qui s’exprime dans la dualité de l’être et de l’existence, de l’immédiat et du médiat, de l’absolu et du moi, de l’infini et du fini, ne manque pas de nous conduire à une difficulté de principe, reconnue en tant que telle dans la philosophie postkantienne : comment l’être se rapporte-t-il à l’existence ? Posant la question de l’être pour parvenir au sens de l’être même, Henry s’inscrit, consciemment ou non, dans une telle problématique, en considérant le chemin vers l’être comme une sortie de la finitude. Si tel est le cas et si l’être se définit comme immanence et vie, comment affronte-t-il la question de la relation entre l’immanence et la transcendance ?
« Le tiers me regarde dans les yeux d’autrui »
Authors: Kotegawa Shojiro
Published: April 2021

Pour envisager notre société, il y a deux positions majeures : le libéralisme qui affirme la liberté de l’individu comme principe politique suprême, et le communautarisme qui privilégie l’intérêt de la communauté sur celui des individus qui la composent. Chaque approche a sa légitimité, mais en même temps sa difficulté : la première, prenant la société pour la limitation ou plutôt l’expansion de la liberté de l’individu, ne peut traiter que négativement notre rapport aux faibles ; la seconde, concevant la communauté comme « donnée », risque de négliger la manière dont l’individu y adhère. Dans sa réflexion sur le « tiers », Levinas a frayé une troisième voie qui nous délivre de cette antinomie. En refusant de prendre la liberté de l’individu ou la communauté pour « données » et d’accorder à l’une ou l’autre la priorité absolue, Levinas aborde la société à partir de la relation avec autrui, laquelle « précède » la communauté ou la loi universelle mais aussi la « conditionne ».
« Auto-affection et événement »
Authors: Walton Roberto J.
Published: April 2021

Cette contribution témoigne de l’importance de la réception de la phénoménologie de langue française en Amérique Latine. En revisitant la thèse de la duplicité de l’apparaître – apparaître de la vie comme affect et comme force, apparaître du monde comme sens et distance –, Roberto J. Walton s’attache au concept fondamental de la phénoménologie de la vie, en mettant en avant des modalités dans lesquelles l’auto-affection opère sans hétéro-affection d’une manière avérée. Il précise d’emblée que cette auto-affection sans hétéro-affection est définie par deux aspects : un premier « aspect de base » – ou rapport de fondation – en vertu duquel l’auto-affection est la condition de possibilité de toute intentionnalité ou ek-stase ; et un deuxième aspect « d’intensification ou d’excédence » qui renvoie à la phénoménologie de l’événement, en ceci que l’auto-affection y apparaît dans une sorte de plus-value, c’est-à-dire dans la condition de l’acte comme accroissement créateur.
La critique de la déraison économique chez Michel Henry
Authors: Leclercq Jean
Published: April 2021

Jean Leclercq livre une étude où il pointe d’abord quelques constats qui en appellent à la nécessité de penser philosophiquement l’argent. Il met ainsi en avant ce qu’il considère les « affres de la réduction mercantile », notamment celles qui nuisent à la valeur de nos liens sociaux, tout en montrant les problèmes philosophiques soulevés par une telle situation. Il aborde ensuite la spécificité et la pertinence du traitement que M. Henry réserve à cette question pour en tirer une conclusion effective, à savoir « penser politiquement l’argent ». Son étude se termine en soulevant des champs d’action, tels que la régulation des usages, la nécessité de penser l’argent dans son rapport à la citoyenneté, les dénonciations des logiques marchandes, la réflexion radicale et renouvelée sur les politiques fiscales, et la réflexion sur la nécessité de libérer des domaines de la vie sociétale de liens d’effectivité avec l’argent, en sorte de « sanctuariser l’inévaluable ».
L' essence de l’apparaître chez Henry et Patočka
Authors: Ortega Rodríguez Iván
Published: April 2021

Iván Ortega Rodríguez livre une contribution où M. Henry est mis en confrontation avec Patočka, notamment sur la corrélation entre la vie et le monde, autrement dit sur l’« a priori de corrélation ». Comme le rappelle l’auteur de cette étude, tant Patočka que M. Henry adoptent cette corrélation a priori comme point de départ, et donc eu égard aux questions portant respectivement sur l’apparaître, sur ce qui apparaît et sur cette vie subjective qui semble devoir accompagner toute donation. Aussi Iván Ortega Rodríguez soutient-il que tout semble se jouer entre M. Henry et Patočka dans leur conception de l’apparaître. Autant la donation henryenne nous invite à nous singulariser dans notre expérience selon le pathos de la vie auto-affective, autant elle nous invite chez Patočka à sortir hors de nous-mêmes selon la priorité accordée à l’aspect de « champ » que nous trouvons dans le se-montrer, là où se place tout ce qui est donné.
Travail, mesure et temps
Authors: Touboul Hervé
Published: April 2021

Apres avoir reconnu la justesse du geste henryen, consistant à placer l’individu vivant au centre de son interprétation, c’est l’atomisation voire l’approche « nominaliste » du travail qui en découle qu’Hervé Touboul met vigoureusement en question, au fil d’une analyse approfondie de la manière dont M. Henry en viendrait à méconnaitre les dialectiques, toujours à l’œuvre dans le texte de Marx, de la quantité et de la qualité, ou de la valeur d’usage et de la valeur d’échange. L’auteur pense décisif d’interroger la posture henryenne : la conception réductrice du travail – comme qualité pure et refus de l’objectivité, au nom de la subjectivité transcendantale. D’où la difficulté à aborder la socialité du travail – les médiations dont elle est tissée, son anonymat irréductible à toute inter-personnalité – et au-delà, à dégager les conditions de sa répétition proprement politique.
Influência da orientação das ranhuras superficiais na flexão rotativa de fios de níquel-titânio
Authors: Lopes Helio Pereira , Elias Carlos Nelson , Ferreira Ligia Martins , Souza Leticia Chaves de , Lopes Weber Schmidt Pereira , Silva Emmanuel João Nogueira Leal , Vieira Victor Talarico Leal
Published: April 2021

Objetivo: Testar a hipótese nula de que a orientação das ranhuras superficiais não influencia na vida em fadiga de fios de níquel-titânio (NiTi). Material e Métodos: Segmentos de fio de NiTi (Moreli, Sorocaba/SP, Brasil) medindo 30mm e com diâmetro de 0,40mm fo- ram utilizados. As ranhuras foram criadas em relação à direção longitudinal, em 45 e 90 graus. O fio foi analisado sob microscopia eletrônica de varredura e a rugosidade, quantificada por interferometria. O número de ciclos para a fratura (NCF) foi determinado pelo teste de flexão rotativa. Resultados: A rugosidade entre os grupos de 45 e 90 graus apresentou diferenças estatisticamente significativas (p<0,05). O grupo sem ranhuras apresentou o maior NCF (p<0,05). O grupo com ranhuras em 45 graus apresentou maior NCF, em comparação ao grupo com 90 graus (p<0,05). Conclusões: A direção das ranhuras possui influência na vida em fadiga dos fios de NiTi. O NCF aumenta com a redução do ângulo das ranhuras em relação ao longo eixo do fio, indepen- dentemente da profundidade das ranhuras.
Revisão sistemática sobre ferimentos por arma de fogo em face: estado da arte e lacunas
Authors: Maia Adriane Batista Pires , Assis Simone Gonçalves , Minayo Cecília
Published: April 2021

Introdução: O tratamento de pacientes vítimas de ferimentos por arma de fogo (FAF) em face normalmente representa um dos maiores desafios para o cirurgião. Diante desse desafio, é necessário conhecer o que a literatura científica recomenda sobre o tratamento desses ferimentos. Objetivo: Sistematizar a produção bibliográfica sobre a ocorrência de ferimentos por arma de fogo em face, além de mapear, na literatura, as evidências existentes e identificar as principais fontes, as temáticas estudadas e as lacunas existentes. Método: Essa revisão utilizou o método scoping, tendo sido realizada em bases bibliográficas eletrônicas brasileiras e internacionais e literatura cinzenta (BVS, Scopus, Web of Science, Pubmed, Lilacs, SciELO, Medline, Sociological Abstract, Cochrane Library, Biblioteca Digital Brasileira de Teses e Dissertações [BTDB], Acervos de Teses Fiocruz), sem estipulação de recorte temporal ou territorial. Resultados: Foram encontrados e analisados 111 documentos, notando-se aumento crescente de publicações entre 2010 e 2019, a maioria publicada em inglês, de procedência norte-americana. Os ferimentos por arma de fogo em face são mais frequentes entre pacientes do sexo masculino, com idade entre 29 e 39 anos. Os temas mais encontrados sobre o trauma balístico facial, em ordem decrescente foram: tratamento cirúrgico, complicações, reconstruções e enxertias, perfil demográfico, tentativas de suicídio, exames complementares para diagnóstico e planejamento cirúrgico e outros temas. Conclusão: Apesar do crescente número de publicações sobre FAF em face, há uma relevante lacuna de estudos voltados para a prevenção e que avaliem repercussões funcionais e psicossociais desse tipo de morbidade.

Published: April 2021

O propósito deste trabalho foi o reconhecimento taxonômico dos fitofósseis oriundos do Membro Crato, Formação Santana da Bacia do Araripe armazenados no Laboratório de Ecologia e Geociências da UFBA, no Campus Anísio Teixeira. Os espécimes estudados totalizaram cinquenta e dois. A princípio foi feito um levantamento dos táxons de plantas fossilizadas já descritos para o Membro citado. Na sequência, o material foi fotografado e deu-se início a identificação, intentando alcançar o táxon de menor nível da classificação possível. Nesta etapa foram analisadas as morfologias dos órgãos preservados e comparadas àquelas das espécies paleobotânicas descritas em trabalhos prévios. Realizada a identificação dos espécimes estudados com suas respectivas espécies, foi feita uma descrição minuciosa de cada espécime. Apenas gimnospermas e angiospermas foram identificadas, sendo o primeiro grupo o mais representativo, especialmente pelas coníferas.
Complex geodesics in convex domains and ℂ-convexity of semitube domains

Hyperbolic torsion polynomials of pretzel knots
Authors: Morifuji Takayuki , Tran Anh T.
Published: April 2021

In this paper, we explicitly calculate the highest degree term of the hyperbolic torsion polynomial of an infinite family of pretzel knots. This gives supporting evidence for a conjecture of Dunfield, Friedl and Jackson that the hyperbolic torsion polynomial determines the genus and fiberedness of a hyperbolic knot. The verification of the genus part of the conjecture for this family of knots also follows from the work of Agol and Dunfield [1] or Porti [19].

Organic electrochemistry: Synthesis and functionalization of β-lactams in the twenty-first century
Authors: Bortolami Martina , Chiarotto Isabella , Mattiello Leonardo , Petrucci Rita , Rocco Daniele , Vetica Fabrizio , Feroci Marta
Published: April 2021

Organic electrochemistry is a technique that allows for the heterogeneous redox reactions avoiding both the use of stoichiometric amounts of redox reagents and the resulting formation of stoichiometric by-products. In fact, the redox reagent in these reactions is the electron, which is naturally eco-friendly and produces no side compounds. It is therefore quite obvious that electrochemistry can be classified as a “green” technology. The use of this methodology in the synthesis of β-lactams is not a novelty, but the growing interest in this class of biologically active compounds, due to the discovery of new fields of application (after a moment of decrease in interest due to antibiotic resistance) has been a stimulus for the search for more efficient electrochemical ways to synthesize and transform β-lactams. Thus, this review deals with the twenty-first-century applications of electroorganic technique to the chemistry of β-lactams, by analyzing first the syntheses classified by the type of reactions (cyclization, cycloaddition, etc.) and then by manipulating the β-lactam structure, using it as a synthon. Lastly, the importance of this technique is demonstrated by a study of a pilot plant scale reduction of a cephalosporanic acid derivative to a commercially important antibiotic.
New graph algorithms via polyhedral techniques
Authors: Tarnawski Jakub
Published: April 2021

This article gives a short overview of my dissertation, where new algorithms are given for two fundamental graph problems. We develop novel ways of using linear programming formulations, even exponential-sized ones, to extract structure from problem instances and to guide algorithms in making progress.

The first part of the dissertation addresses a benchmark problem in combinatorial optimization: the asymmetric traveling salesman problem (ATSP). It consists in finding the shortest tour that visits all vertices of a given edge-weighted directed graph. Aρ-approximation algorithm for ATSP is one that runs in polynomial time and always produces a tour at mostρtimes longer than the shortest tour. Finding such an algorithm with constantρhad been a long-standing open problem. Here we give such an algorithm.

The second part of the dissertation addresses the perfect matching problem. We have known since the 1980s that it has efficient parallel algorithms if the use of randomness is allowed. However, we do not know if randomness is necessary – that is, whether the matching problem is in the classNC. We show that it is in the classquasi-NC. That is, we give a deterministic parallel algorithm that runs in poly-logarithmic time on quasi-polynomially many processors.
An inverse problem of radiative potentials and initial temperatures in parabolic equations with dynamic boundary conditions
Authors: Ait Ben Hassi El Mustapha , Chorfi Salah-Eddine , Maniar Lahcen
Published: April 2021

We study an inverse problem involving the restoration of two radiative potentials, not necessarily smooth, simultaneously with initial temperatures in parabolic equations with dynamic boundary conditions. We prove a Lipschitz stability estimate for the relevant potentials using a recent Carleman estimate, and a logarithmic stability result for the initial temperatures by a logarithmic convexity method, based on observations in an arbitrary subdomain.
Ernst Cassirer’s Legacy: History of Philosophy and History of Science
Authors: Ferrari Massimo
Published: April 2021

The paper is devoted to an overview of Cassirer’s work both as historian of philosophy and historian of science. Indeed, the “intelletcual cooperation” between history of philosophy and history of science represents an essential feature of Cassirer’s style of philosophizing: while the roots of a wide exploration stretching from Renaissance thought to modern physics go back to the Neo-Kantianism of the Marburg School, the results of a similar cross-fertilization of research fields have deeply contributed to shaping new standards of inquiry. Cassirer’s relationship with the Warburg milieu in Hamburg and late in his life with the American intellectual scenario (for instance, with the “Journal of History of Ideas”) are surely worthy of closer investigation. Distinguished scholars such as Meyerson, Brunschvicg, Burtt, Koyré, Metzger, Lovejoy, Kristeller, have disussed, appreciated, critizised Cassirer’s still today fascinating studies devoted to Pico della Mirandola, Galileo, Newton, Leibniz, to mention but a few. To explore some of these aspects focusing both on affinities and differences within a cosmpolitian intellectual community can provide a better understanding of philosophy and history of science in the first half of 20th century. Cassirer’s legacy requires, therefore, a new assessment.
Long-term stress level in a small mammal species undergoing range expansion
Authors: André Adrien , Michaux Johan , Gaitan Jorge , Millien Virginie
Published: April 2021

Rapid climate change is currently altering species distribution ranges. Evaluating the long-term stress level in wild species undergoing range expansion may help better understanding how species cope with the changing environment. Here, we focused on the white-footed mouse (Peromyscus leucopus), a widespread small mammal species in North-America whose distribution range is rapidly shifting northward. We evaluated long-term stress level in several populations of P. leucopus in Quebec (Canada), from the northern edge of the species distribution to more core populations in Southern Quebec. We first tested the hypothesis that populations at the range margin are under higher stress than more established populations in the southern region of our study area. We then compared four measures of long-term stress level to evaluate the congruence between these commonly used methods. We did not detect any significant geographical trend in stress level across our study populations of P. leucopus. Most notably, we found no clear congruence between the four measures of stress level we used, and conclude that these four commonly used methods are not equivalent, thereby not comparable across studies.
Cooperative optical wavefront engineering with atomic arrays
Authors: Ballantine Kyle E. , Ruostekoski Janne
Published: April 2021

Natural materials typically interact weakly with the magnetic component of light which greatly limits their applications. This has led to the development of artificial metamaterials and metasurfaces. However, natural atoms, where only electric dipole transitions are relevant at optical frequencies, can cooperatively respond to light to form collective excitations with strong magnetic, as well as electric, interactions together with corresponding electric and magnetic mirror reflection properties. By combining the electric and magnetic collective degrees of freedom, we show that ultrathin planar arrays of atoms can be utilized as atomic lenses to focus light to subwavelength spots at the diffraction limit, to steer light at different angles allowing for optical sorting, and as converters between different angular momentum states. The method is based on coherently superposing induced electric and magnetic dipoles to engineer a quantum nanophotonic Huygens’ surface of atoms, giving full 2π phase control over the transmission, with close to zero reflection.
A simplified kinetic model for modern cooking of aspen chips
Authors: Gilbert Wesley , Allison Bruce , Radiotis Theodore , Dort Arnold
Published: April 2021

Kraft pulping kinetic models are an important component of any fundamental continuity based continuous digester model. These models can be used to further develop our understanding, or as a framework to support the development of real-world control, estimation and optimization strategies. Effective models are tailored to a specific species of wood and must be applicable for a wide range of expected cooking conditions. In this work a series of experiments were conducted on hardwood Aspen chips for 5 different cooking conditions. Each series of cooks were interrupted at different time intervals to capture the dynamic response of the cook. The key chips and liquor components were measured and reconciled at each interval.

A dynamic model was then developed based on a simplification of a continuous digester model under batch conditions. This ensures continuity between the key assumptions governing both the batch kinetics model and the expanded continuous form. A kinetic model structure was adapted from the literature that quantifies all three accepted phases of lignin and cellulose degradation, i. e. the initial, bulk and residual phases as well as the effect of modern cooking practices such as intra-cook white liquor addition on the transition between the bulk and residual phases. Additionally, modifications were made to the kinetic model structure to reduce the overall number of states and to impose a floor limit on degradation, thereby reducing the overall complexity and computational burden. The model was then fit to the data using weighted least squares and simulation optimization techniques.
A Diachronic Maltese Islandscape: Rural Ta’ Qali and ix-Xarolla
Authors: Vella Clive , Spiteri Mevrick
Published: April 2021

The archaeological study of the Maltese Islands has received considerable scholarly attention in regard to its island settings and long-term human occupation. However, emphasis on the prehistoric periods of the archipelago runs the risk of creating a biased focus with limited engagement in successive periods. In the spirit of this edited volume, the present article seeks to provide a broader chronological view of two rural areas in the larger island of Malta: Ta’ Qali and ix-Xarolla. These two areas have offered some evidence, through intermittent discoveries from recent construction activities, of three broad periods of increased landscape manipulation and transformation during the Middle-Late Bronze Age, Roman, and Early Modern periods. In seeking to provide an islandscape-based narrative, this article seeks to show that the Maltese Islands experienced periods of more intense human occupation that would have inevitably impacted the agriculturally viable areas of Ta’ Qali and ix-Xarolla. Therefore, despite the Roman period focus of this edited volume, this article takes a long-term view of two rural areas to illustrate identifiable landscape uses and changes.
Ecclesial Belonging in a World of Pure Experience: William James, W. E. B. Du Bois, and Religious Rationality in Crisis
Authors: Stepanenko Walter Scott
Published: April 2021

The global COVID-19 pandemic has spotlighted several instances of churches violating state issued and scientifically recommended guidelines designed to keep populations healthy and to prevent the further spread of the disease. While these instances are minority responses to these orders, they nonetheless raise questions about the rationality of ecclesial belonging in response to the COVID-19 pandemic. In this article, I draw on the work of William James and W. E. B. Du Bois to articulate a conception of ecclesial belonging as a social epistemological process engaging a complex, fluid multiplicity of knowers of various scales. I argue that, in this view, ecclesial rationality involves the construction of a concatenation of internal and external practices individual believers and groups can traverse so long as they consistently satisfy a plurality of desiderata. I suggest that what is irrational about religious-based defiance of COVID-19 guidelines is the church-sanctioned severance of internal from external practices. I suggest that this behavior is supported by a failure to grasp the demands of ecclesial rationality rather than embrace them, and that this conception of rationality may have been eroded by the value-neutral skepticism of secular rationality.
Voice onset time and constriction duration in Warlpiri stops (Australia)

This paper presents a first detailed analysis of the Voice Onset Time (VOT) and Constriction Duration (CD) of stops /p t ʈ c k/ and flap /ɽ/ in the Indigenous Australian language Warlpiri as spoken in Lajamanu Community, in Australia’s Northern Territory. The results show that Warlpiri stops are realised as voiceless, long-lag stops word-initially, as well as word-medially, where /p t k/ are also characterised by CDs in excess of 100 ms. This is similar to what has been reported for Kriol, and for the emerging mixed language Light Warlpiri, also spoken in the community, and by some of the participants. The results indicate that Warlpiri does not obligatorily make a word-medial distinction between stops orthographically represented by ‘rt’ and ‘rd’, which have previously been argued to be realised as /ʈ/ and /ɽ/, respectively, at least in some varieties of Warlpiri. Finally, the results also suggest that the realisation of word-initial Warlpiri flap /ɽ/ is highly variable, potentially resulting in a near-merger with /ɻ/.
Dissolving pulp production: Cellulases and xylanases for the enhancement of cellulose accessibility and reactivity
Authors: Kumar Amit
Published: April 2021

Dissolving pulps are high-grade cellulose pulps that have minimum amount of non-cellulosic impurities. Dissolving pulps are the basic source for the manufacturing of several cellulosic products such as viscose, lyocell, cellulose acetates, cellulose nitrates, carboxymethyl-cellulose, etc. Dissolving pulps are mainly manufactured by pre-hydrolysis kraft and acid sulphite pulping. A high reactivity of dissolving pulps is desirable for its eco-friendly utilization for several purposes. Several approaches including mechanical, chemical, ultrasonic, and enzymatic treatments have been employed for the improvement of pulp reactivity. This review mainly focussed on pulp reactivity improvement through enzymatic approaches. Cellulases and xylanase have been proved effective for the improvement of pulp reactivity of dissolving pulp from different sources. The different combinations of cellulase, xylanase, and mechanical refining have been tested and found more effective rather than the single one.

Objectives

There is no reliable and valid biomarker to identify Irritable bowel syndrome (IBS) and its subtypes. The aim of this study is to explore potential serum biomarkers that may be associated with IBS subtypes, particularly in the vitamin D pathway.

Methods

The study population comprised 75 IBS patients and 79 controls. Patients divided into IBS subtypes. Routine biochemical parameters, 25-OH-vitamin D, vitamin D binding protein (VDBP) and vitamin D receptor (VDR) serum levels were compared between IBS subtypes and controls. Factors related to IBS subtypes were examined by multivariate logistic regression analysis.

Results

Vitamin D levels were lower; VDBP and VDR were higher in all IBS patients than in controls (p<0.001; 0.047 and 0.029, respectively). According to logistic regression analysis, VDBP was a disease-related parameter as much as vitamin D in all IBS subtypes. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were higher especially in diarrhea-dominant IBS (IBS-D) (p=0.041; 0.046) and vitamin B12 were significantly lower in constipation-dominant IBS (IBS-C) (p=0.001).

Conclusions

Increased VDBP levels were associated with all IBS subtypes. Patients, especially in IBS-D, had higher serum levels of VDBP, CRP and ESR. Vitamin B12 deficiency, which we consider as a result of the disease, was more common in IBS-C.
On event-denoting deadjectival nominalizations
Authors: Arche María J. , Fábregas Antonio , Marín Rafael
Published: April 2021

This paper offers a principled account for the nominalizations of dispositional evaluative adjectives. On the descriptive side, the paper shows that (i) in addition to the largely studied deverbal nominalizations, certain deadjectival nominalizations can also refer to events; (ii) the types of adjectives that enable eventive denotation are of a specific sort, namely, those deriving from Dispositional Evaluative Adjectives (e.g.,imprudent). At the theoretical level, this paper argues that (i) dispositional deadjectival nominalizations introduce an event description not in a head but in a specifier position, as their subject of predication; (ii) in order for a word to have functional structure of the sort associated to verbs, an event description is not enough: functional projections must form a head-sequence with the event-descriptive heads; without this configuration, the merge of a fully-fledged verbal functional structure is blocked, which explains the limitations regarding temporal modification; (iii) The event present in the dispositional deadjectival nominalizations is a partial event description consisting of a head referring to the Process subevent.
Europaals mentales Modell in den Köpfen von Lernenden

Published: April 2021

The paper discusses concept maps as an instrument for the collection and reconstruction of lexical-semantic coded knowledge and demonstrates to what extent the elicited data can be interpreted as representations of mental models using onomosiological and framesemantic approaches. To this end, a theoretical framework is presented that discusses and legitimizes the use of concept maps due to their similarity to the ordering principles and structures of the mental lexicon. Finally, the application of thise tool, i. e. the concept maps, will be illustrated and discussed using one example from a more extensive pilot project conducted by the international EurEd research network.

Vitamin D deficiency is associated with symptoms of skeletal muscle myopathy including muscle weakness and fatigue. Recently, vitamin D-related metabolites have been linked to the maintenance of mitochondrial function within skeletal muscle. However, current evidence is limited to in vitro models and the effects of diet-induced vitamin D deficiency upon skeletal muscle mitochondrial function in vivo have received little attention. In order to examine the role of vitamin D in the maintenance of mitochondrial function in vivo, we utilised an established model of diet-induced vitamin D deficiency in C57BL/6J mice. Mice were either fed a control diet (2200 IU/kg i.e. vitamin D replete) or a vitamin D-deplete (0 IU/kg) diet for periods of 1, 2 and 3 months. Gastrocnemius muscle mitochondrial function and ADP sensitivity were assessed via high-resolution respirometry and mitochondrial protein content via immunoblotting. As a result of 3 months of diet-induced vitamin D deficiency, respiration supported via complex I + II (CI + IIP) and the electron transport chain (ETC) were 35 and 37% lower when compared to vitamin D-replete mice (P < 0.05). Despite functional alterations, citrate synthase activity, AMPK phosphorylation, mitofilin, OPA1 and ETC subunit protein content remained unchanged in response to dietary intervention (P > 0.05). In conclusion, we report that 3 months of diet-induced vitamin D deficiency reduced skeletal muscle mitochondrial respiration in C57BL/6J mice. Our data, when combined with previous in vitro observations, suggest that vitamin D-mediated regulation of mitochondrial function may underlie the exacerbated muscle fatigue and performance deficits observed during vitamin D deficiency.
Thermal influence on the mechanical properties of cardboard during an ultrasonic-assisted embossing process

Published: April 2021

During the embossing process, a fiber sandwich is compressed between embossing tools. The use of ultrasound causes a short-term increase in the material temperature in addition to causing plastic deformation. The combination of the material compression and an increase in material temperature leads to structural changes, which can be observed by the change in mechanical properties of the cardboard. This work investigated the influence of an ultrasonically induced temperature increase on the structural changes of cardboard. Using three-parameter combinations, different temperature levels were achieved with a material densification of less than 5%. Subsequently, the samples were subjected to selected physical and visual analyses to characterize the change in the fiber structure. With the increase of 124 ºC material temperature there was a decrease of about 15% in the splitting resistance and 10% in the bending stiffness.

Aim. To evaluate and compare effectivenes of sacral and posterior tibial nerve stimulation for treating fecal incontinence.Methods. Systematic literature review was performed to compare sacral and posterior tibial nerve stimulation effectiveness. Research was performed in “Medline” database, using the “PubMed” website. English or lithuanian articles, published between 2008 and 2019, were included in our study. Results were described to assess the effect of interventions in each analysed article. We included 7 articles into meta-analysis. Articles compared the effectiveness of sacral or posterior tibial nerve stimulation with control groups or other treatment methods for managing fecal incontinence. Cochrane guidelines were used to perform this meta-analysis. Results. The results of meta-analysis suggests that sacral neuromodulation is superior to posterior tibial nerve stimulation to treat fecal incontinence compared to control groups or other treatments. Literature also suggest that after comparing these methods directly, sacral neuromodulation is superior to treat fecal incontinence a. Conclusion. Sacral neuromodulation is superior posterior tibial nerve stimulation to treat temporary or chronical fecal incontinence than and can be used as an alternative for surgical interventions.

Cystic fibrosis (CF) is an autosomal dominant disease characterized by the dysfunction of exocrine secretory glands resulting from a mutation in the transmembrane regulator protein (CFTR) gene. As life expectancy increases in patients with cystic fibrosis secondary to advances in treatment, advanced age malignancies secondary to cystic fibrosis emerge. Especially, the frequency of gastrointestinal system malignancies and colon cancers increases with aging. Appendiceal tumors are a rare entity and constitute less than 1% of gastrointestinal tumors. We presented a villous adenoma encountered in an 18-year-old male patient with CF accompanied by clinical and radiological findings. Our case is the first reported appendiceal tumor that emerged in patients with cystic fibrosis.
Exploring the Meaning of Therapeutic Horticulture for Anishinabek Youth in a Brief Residential Treatment Unit: A Community Engagement CSL Case Study
Authors: Nelson Connie H. , Uvanile Michelle , Vinni Judi , Schiff Rebecca
Published: April 2021

This paper explored community-university engagement that integrated a short-term treatment facility for Indigenous youth, a social enterprise organization that focused on healing through horticulture therapy experiences and an interdisciplinary academic team. The focus was to discover whether a horticulture therapy (HT) approach held promise in terms of an appropriate way to expand community service-learning (CSL) with Indigenous peoples and to encourage more diversity of voices in community service-learning experiences. Youth participants took part in a photovoice study and further semi-structured interviews to document their perspectives on the meaning of their horticultural experiences. Findings revealed that youth valued the overall HT experience itself; being connected to the gardens and nature and the social interactions exploring spirituality and the self were significant and meaningful for them. Further, findings demonstrated that a collaborative partnership that engaged multiple service agencies to explore novel ways for engaging youth in healing activities with a university team that guided the research approach holds promise as a CSL with Indigenous youth. We conclude with recommendations on the significance of community-university engagement in delivering therapeutic horticulture programs for Indigenous youth as a community service-learning initiative.
Review of Settler City Limits: Indigenous Resurgence and Colonial Violence in the Urban Prairie West by Heather Dorries, Robert Henry, David Hugill, Tyler McCreary, and Julie Tomiak (Eds.). Winnipeg, MB: University of Manitoba Press, 2019.
Authors: Baker Jillian
Published: April 2021

Opening with the definitive (and ultimately central) assertion that “[cities] are places where Indigenous peoples have continually resisted and challenged the normalizations of settler colonial violence” (p. 1), Settler City Limits: Indigenous Resurgence and Colonial Violence in the Urban Prairie West is a well-woven collection of essays, each of which pulls at the frayed edges of colonial narratives that continually dress and address the “city” as a distinctly settler space.
