SOTERIOLOGI MENURUT PAULUS SEBAGAI DASAR TRADISI BAGI PELAKSANAAN PENDIDIKAN AGAMA DALAM KONTEKS PLURALISME DI INDONESIA
Authors: Nataniel Demianus
Published: January 2020

Ronald H. Cram said “the radical dialogue is an appropriate religious education model in pluralism context”. He contended that the radical dialogue consists of the hospitality principles that goes beyond tolerance. Unfortunately, his argumentations have not been based on the biblical tradition. In this paper, therefore, I would like to propose soteriology of the cross in Paul’s letters as a supporting tenet for implementing the radical dialogue in religious education, especially in Indonesian pluralism context. Based on the principles of soteriology of the cross in Paul’s letters, Christian comunity in Indonesia will be provoked to implement the radical dialogue. In order to clarify how the principles of soteriology of the cross are approprieated with the concept of the radical dialogue, I will delineate an Indonesian pluralism context succintly and an appropriate model of religious education in the context respectively.
MELIHAT KEMUNGKINAN MODUS GEREJA SEBAGAI DASAR BAGI PENYUSUNAN MUSIK UNTUK HYMN
Authors: Sema Daniel
Published: January 2020

The standard major and minor scale have been used to compose millions of congregational song. After years of listening to music based on the same old scales, there is a way to break away from convention but still keep the music interested and more fresh. A great way to start exploring interesting and new sounding melodies and harmonies is to use modes (church modes). Modes are scales that use the same pitches of the standard major scale but in new and different ways. Because of one or two discrepancies from the typical major or minor scale, a mode can sound fresh, intriguing, and grab your listener's attention as something new.

We perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence during the first two months of the TESS mission. Flares may erode exoplanets’ atmospheres and impact their habitability, but might also trigger the genesis of life around small stars. TESS provides a new sample of bright dwarf stars in our galactic neighborhood, collecting data for thousands of M dwarfs that might host habitable exoplanets. Here, we use an automated search for flares accompanied by visual inspection. Then, our public allesfitter code robustly selects the appropriate model for potentially complex flares via Bayesian evidence. We identify 1228 flaring stars, 673 of which are M dwarfs. Among 8695 flares in total, the largest superflare increased the stellar brightness by a factor of 16.1. Bolometric flare energies range from 1031.0 to 1036.9 erg, with a median of 1033.1 erg. Furthermore, we study the flare rate and energy as a function of stellar type and rotation period. We solidify past findings that fast rotating M dwarfs are the most likely to flare and that their flare amplitude is independent of the rotation period. Finally, we link our results to criteria for prebiotic chemistry, atmospheric loss through coronal mass ejections, and ozone sterilization. Four of our flaring M dwarfs host exoplanet candidates alerted on by TESS, for which we discuss how these effects can impact life. With upcoming TESS data releases, our flare analysis can be expanded to almost all bright small stars, aiding in defining criteria for exoplanet habitability.
Models of the Mass-ejection Histories of Pre-planetary Nebulae. IV. Magnetized Winds and the Origins of Jets, Bullets, and FLIERs
Authors: Balick Bruce , Frank Adam , Liu Baowei
Published: January 2020

This paper explores the influences and consequences of toroidal magnetic fields in shaping the visible lobes of pre-planetary nebulae (prePNe). To probe these influences we start with the steady, diverging, and field-free wind model of our previous papers and add weak to moderate toroidal fields to the winds in order to generate arrays of outcomes after 500 yr, after which the structures grow almost homologously. As expected, toroidal fields in the stellar winds invariably form very thin and dense axial features whose structure is best described as a thin cold jet with an ultra-dense and neutral leading knot, or bullet, at its tip. The speed of the leading knot depends only on the density contrast (the ratio of injected to ambient gas densities at the nozzle) and wind injection speed, but not on the field strength or opening angle. The lobes formed by the ram pressure of the winds take a variety of forms and sizes that depend primarily on the geometric structure of the injected gas and the density contrast. About 20% of the Hubble Space Telescope images of prePNe show unique signatures of shaping by toroidal fields. Pairs of low-ionization knots seen along the major axis of fully ionized PNe, often called FLIERs, are easily explained as the very dense, cold, and neutral remnants of magnetically formed knots.
Probing the Emission States of PSR J1107−5907

The emission from PSR J1107−5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very bright. In order to improve our understanding of these state changes, we have identified archival data sets from the Parkes radio telescope in which the bright emission is present, and find that the emission never switches from the bright state to the weak state, but instead always transitions to the “off” state. Previous work had suggested the identification of the “off” state as an extreme manifestation of the weak state. However, the connection between the “off” and bright emission reported here suggests that the emission can be interpreted as undergoing only two emission states: a “bursting” state consisting of both bright pulses and nulls, and the weak emission state.
Hubble Space Telescope Observations of Mira Variables in the SN Ia Host NGC 1559: An Alternative Candle to Measure the Hubble Constant

We present year-long, near-infrared Hubble Space Telescope (HST) WFC3 observations used to search for Mira variables in NGC 1559, the host galaxy of the Type Ia supernova (SN Ia) SN 2005df. This is the first dedicated search for Miras, highly evolved low-mass stars, in an SN Ia host, and subsequently the first calibration of the SN Ia luminosity using Miras in a role historically played by Cepheids. We identify a sample of 115 O-rich Miras with P < 400 days based on their light-curve properties. We find that the scatter in the Mira period–luminosity relation (PLR) is comparable to Cepheid PLRs seen in SN Ia host galaxies. Using a sample of O-rich Miras discovered in NGC 4258 with HSTF160W and its maser distance, we measure a distance modulus for NGC 1559 of

(statistical)

(systematic) mag. Based on the light curve of the normal, well-observed, low-reddening SN 2005df, we obtain a measurement of the fiducial SN Ia absolute magnitude of

mag. With the Hubble diagram of SNe Ia we find

km s−1 Mpc−1. Combining the calibration from the NGC 4258 megamaser and the Large Magellanic Cloud detached eclipsing binaries gives a best value of

km s−1 Mpc−1. This result is within 1σ of the Hubble constant derived using Cepheids and multiple calibrating SNe Ia. This is the first of four expected calibrations of the SN Ia luminosity from Miras that should reduce the error in H
0 via Miras to ∼3%. In light of the present Hubble tension and JWST, Miras have utility in the extragalactic distance scale to check Cepheid distances or calibrate nearby SNe in early-type host galaxies that would be unlikely targets for Cepheid searches.
Deep Hubble Space Telescope Imaging on the Extended Lyα Emission of a QSO at z = 2.19 with a Damped Lyman Alpha System as a Natural Coronagraph

Published: January 2020

Recent observations suggest that proximate damped Lyα (PDLA) systems can be used to study the host galaxies of quasi-stellar objects (QSOs), because the PDLAs can block the bright point-spread function from central QSOs. Using six orbits of narrowband imaging with Hubble Space Telescope (HST)/WFC3, we present the first high-resolution narrowband image of the Lyα emission in the PDLA trough of the QSO SDSS J115432.67–021537.9. We detect one major component and one minor component in the narrowband imaging. Combining the

/WFC3 imaging with deep Magellan/MagE spectra, we measure that the Lyα flux

=

, which is among the luminous (≈2.7

) Lyα emitters at

2.19. The

-based star formation rate is ∼7

. These observational results favor that the star formation from the host galaxy could be the main mechanism powering the Lyα emission. This new method sheds light on the study of the kinematic structure and the spatial distribution of the extended Lyα emitting regions around the QSO host.
Detection of a Water Tracer in Interstellar Comet 2I/Borisov

Published: January 2020

We present high spectral resolution optical spectra obtained with the ARCES instrument at Apache Point Observatory showing detection of the [O i] 6300 Å line in interstellar comet 2I/Borisov. We employ the observed flux in this line to derive an H2O production rate of (6.3 ± 1.5) × 1026 mol s−1. Comparing to previously reported observations of CN, this implies a CN/H2O ratio of ∼0.3%–0.6%. The lower end of this range is consistent with the average value in comets, while the upper end is higher than the average value for solar system comets, but still within the range of observed values. C2/H2O is depleted, with a value likely less than 0.1%. The dust-to-gas ratio is consistent with the normal value for solar system comets. Using a simple sublimation model we estimate an H2O active area of 1.7 km2, which for current estimates for the size of Borisov suggests active fractions between 1% and 150%, consistent with values measured in solar system comets. More detailed characterization of 2I/Borisov, including compositional information and properties of the nucleus, is needed to fully interpret the observed H2O production rate.
Gender studies in Communication Degrees
Authors: García-Ramos Francisco-José , Zurian Francisco-A. , Núñez-Gómez Patricia
Published: January 2020

This paper is the result of a research carried out under the umbrella of the “UNESCO UniTWIN Network on Media, Gender, and ICTs” Project, and it tries to determine the presence of subjects with a specific focus on gender in the current Communication Degrees offered at Spanish universities. The inclusion of subjects about gender equality in relation to media follows the suggestions of the IV World Conference on Women in Beijing (1995). The main objective of this research will be to investigate the presence of these subjects in Communication Degrees, identifying the elements that define them at a thematic, methodological and relevant levels within the curriculum. A mixed methodological design is proposed based on ex-post-facto research, with a descriptive orientation and the search for improvement, a qualitative analysis of study plans using ATLAS.ti and a panel of experts. The results reveal a scarce presence of this type of subjects, with a higher percentage in public universities than in private ones, and also a minimal relevance as compulsory subjects. This research study reveals the current formal training in gender studies of future generations of media professionals and serves as an endorsement for forthcoming changes of curricula in the European Higher Education Area context.

El presente trabajo es fruto de una investigación desarrollada en el marco del proyecto «UNESCO UniTWIN Network on Media, Gender, and ICTs» para determinar la presencia de asignaturas con un contenido específico en estudios de género en los actuales planes de estudio de los Grados españoles en el área de comunicación. La inclusión de asignaturas que aborden la igualdad de género en relación a los medios y procesos de comunicación obedece a lo establecido en la IV Conferencia Mundial sobre la Mujer de Beijing (1995). El objetivo principal de este trabajo será la indagación del nivel de presencia de estas asignaturas en los Grados en comunicación identificando los elementos que las definen a nivel temático, metodológico y relevancia dentro del plan de estudios. Se plantea un diseño metodológico mixto partiendo de una investigación ex-post-facto, con orientación descriptiva y de búsqueda de la mejora, un análisis cualitativo de planes de estudio mediante ATLAS.ti y un panel de expertos. Los resultados inciden en una escasa presencia de este tipo de asignaturas, con mayor porcentaje en la universidad pública respecto a la privada y una mínima relevancia como materia obligatoria. Un trabajo que vislumbra la actual formación reglada en cuestiones de género de las futuras generaciones de profesionales de los media y que sirve de apoyo para futuros cambios de planes de estudios en el Espacio Europeo de Educación Superior.
To-friend or not-to-friend with teachers on SNSs: University students' perspectives
Authors: Turan Zeynep , Durdu Levent , Goktas Yuksel
Published: January 2020

A large majority of university students use social networking sites (SNS) actively. Nevertheless, there are very limited studies examining students’ perceptions about student-teacher relationships in SNSs comprehensively. The purpose of this research was to investigate university students’ perceptions about interacting with their teachers in SNSs, and to this end an exploratory mixed-methods design was utilised. Qualitative data were collected from 21 students via interviews, and quantitative data from 1,324 students in 19 universities in Turkey via a questionnaire. Content analysis, descriptive analysis and principal component analysis methods were used to analyse the data. The content analysis contributed to the formulation of the questionnaire items. The principal component analysis yielded the following four dimensions: perceived utility, perceived barriers, perceived favourable teacher behaviours, and perceived unfavourable teacher behaviours. The most prominent finding is that the students were mostly opposed to their teachers’ sharing their political and religious views; however, they were in favour of teachers sharing information about their personal life. Despite some students displaying some hesitation, especially concerning the level of respect between them, the majority of students had a positive outlook towards teacher-student friendships. The students indicated that being friends on SNSs would increase their motivation towards the course.

Para este fin se empleó un diseño exploratorio mediante métodos mixtos. Se recopilaron datos cualitativos de 21 estudiantes por medio de entrevistas y datos cuantitativos de 1.324 sujetos en 19 universidades de Turquía mediante cuestionario. Para analizar los datos se aplicaron análisis de contenido, análisis descriptivo, y análisis de componentes principales. El primero contribuyó a la formulación de los ítems del cuestionario. El análisis del componente principal arrojó cuatro dimensiones: utilidad percibida, barreras percibidas, comportamientos docentes percibidos como favorables y desfavorables. El hallazgo más destacado fue que los estudiantes se opusieron principalmente a que sus profesores compartieran sus puntos de vista políticos y religiosos. No obstante, estaban a favor de que los docentes compartieran información sobre su vida personal. A pesar de que algunos estudiantes mostraron dudas, especialmente con respecto al nivel de respeto entre ellos, la mayoría del alumnado tenía una perspectiva positiva hacia las amistades profesor-alumno. Estos indicaron que ser amigos en las redes sociales aumentaría su motivación hacia el curso.
Domesticated voices and false participation: Anatomy of interaction on transmedia podcasting
Authors: García-Marín David , Aparici Roberto
Published: January 2020

Transmedia podcasting (transpodcast) is an example of a digital medium essentially promoted by a community of independent creators that arises from the technological advancement derived from the arrival of Web 2.0. This medium is considered to offer its users greater possibilities of participation and co-creation by abandoning the traditional communicative models based on unidirectionality. The objective of this work is to determine how audience engagement takes place in this medium, taking into consideration the analysis of its participation spaces. In order to reach this goal, a Mixed Method Research Design was used, integrating two case studies with a total sample of 2,490 units of participation generated by users on the iVoox platform, the blogs of the two selected projects, and messages on Twitter. The research was complemented with an ethnographic investigation through observational methods on the presence of the user’s voice in the podcasts of a total of 19 transpodcast projects. Despite the fact that numerous and relevant voices have defended that the new media ecosystem causes the decentralization and democratization of the agenda-setting and empowers ordinary citizens, this study shows a less optimistic and more critical perspective about the possibilities of meaningful citizen participation in online discourse.

El transpodcast (podcasting transmedia) es un ejemplo de un medio digital desarrollado esencialmente por una comunidad de creadores independientes que surge del avance tecnológico derivado de la Web 2.0. Este medio ofrece a sus usuarios mayores posibilidades de participación y cocreación al abandonar los modelos comunicativos unidireccionales basados en la lógica broadcast, propios del siglo XX. El objetivo de este trabajo es determinar cómo se lleva a cabo la interacción de los usuarios en este medio a partir del análisis de los espacios de participación que despliega el transpodcast. Para ello, se empleó una metodología mixta (Mixed Method Research Design), que integra dos estudios de caso con una muestra total de 2.490 unidades de participación generadas por los usuarios en la plataforma iVoox, blogs de los dos proyectos y mensajes en Twitter. La investigación fue complementada con un estudio etnográfico, ejecutado a través de métodos observacionales sobre la presencia del usuario en los programas en formato podcast de un total de 19 proyectos transpodcast. Aunque numerosas y relevantes voces han defendido que el nuevo ecosistema mediático ha causado la descentralización y la democratización de la agenda-setting y ha empoderado a los ciudadanos en términos comunicacionales, este estudio aporta una perspectiva menos optimista y más crítica sobre las posibilidades reales de participación ciudadana significativa en el discurso online.

Le christianisme oriental au sud du Sinaï vu au prisme des graffiti arabo-chrétiens (ixe-xie siècle)
Authors: Lagaron Anna
Published: January 2020

Cet article s’inscrit dans le domaine de la graffitologie et livre l’étude d’un corpus encore largement méconnu. Répertoriés entre 2001 et 2005 par la mission japonaise au Sinaï (Dir. M. Kawatoko), les graffiti arabes chrétiens présents en grand nombre dans le sud de la péninsule n’avaient, cependant, jamais livré leurs contenus. L’étude des sources du point de vue des formulaires, de l’onomastique et de la paléographie ainsi que la contextualisation historique et épigraphique apportent un éclairage sur l’histoire du christianisme oriental dans la région. L’exploitation des données permet en outre d’esquisser le profil de ces pèlerins chrétiens convergeant vers le Mont Sinaï et informe sur la fréquentation des routes aux époques abbassides et fatimides.
La fidélité à la tradition

Published: January 2020

Cet article étudie trois variations d’un panégyrique dédié à saint Théodore l’Oriental, un saint vénéré en Égypte par les chrétiens coptes orthodoxes égyptiens, principalement en Haute Égypte : une version manuscrite transmise à la fin de l’époque ottomane, une version imprimée dans l’entre-deux-guerres et un enregistrement contemporain. Après avoir mis en évidence les caractères du moyen arabe de la version manuscrite et évoqué la genèse du texte, nous étudions comment et pourquoi l’entreprise éditoriale est une réinvention et une bifurcation de la tradition. Quant à l’oralité, elle apparaîtra autant dans la récitation comme performance singulière, que dans la trame même des textes comme modèle imaginé et trace de performances antérieures.
L’Église melkite au ixe siècle à travers le conflit entre David de Damas et Siméon d'Antioche
Authors: Boudier Mathilde
Published: January 2020

Cet article présente un dossier inédit de documents concernant les chrétiens de Damas à la fin du ixe siècle. Conservés au moyen de leur copie dans deux manuscrits tous deux datables approximativement du xe-xie siècle, ces neuf documents rédigés en arabe ont été produits à l’occasion d’un conflit au sein de l’Église melkite de Syrie en 277/890‑891. Il ressort de l’analyse que David, évêque métropolitain de Damas, a lui-même réuni ces documents à charge contre son adversaire Siméon, patriarche d’Antioche. La plainte de David de Damas aux deux autres patriarches, Élie de Jérusalem et Michel d’Alexandrie, contre Siméon d’Antioche, est éditée et traduite en français en annexe de l’article. La plainte de l’évêque, les réponses et avis juridiques émis par les deux patriarches, la lettre des habitants d’Antioche (ahl Anṭākiya) et, enfin, un jugement antérieur du patriarche Théodose d’Antioche, apportent de précieuses informations sur la hiérarchie ecclésiastique melkite contemporaine et donnent un aperçu du fonctionnement de la justice ecclésiastique et de l’utilisation du droit canonique. Le conflit implique aussi des laïcs chrétiens et musulmans de Damas, autour de l’administration des revenus et des propriétés de l’Église, dont une boulangerie (furn al‑kanīsa). Le pouvoir toulounide figure en arrière-plan d’un conflit essentiellement géré par les autorités ecclésiastiques de l’espace syro‑égyptien.
Kāna sa-yafʿalu et kāna sa-yakūnu qad faʿala
Authors: Sartori Manuel
Published: January 2020

Cet article prolonge les résultats d’une première étude consacrée à la combinaison verbale arabe kāna sa‑yafʿaluʿala, et présente une autre combinaison, inédite celle-ci, en kāna sa‑yakūnu qad fa. Il montre notamment comment ces deux combinaisons sont à entendre comme les équivalents « logiques » (d’un point de vue linguistique) des conditionnels présents et passés de langues comme le français et l’anglais, que ce soit dans les emplois temporels du conditionnel que dans ses emplois modaux. Il permet d’assurer une fois encore que kāna sa‑yafʿalu, s’il peut avoir une lecture modale hypothétique contrefactuelle que le français rend par un conditionnel passé pour dire ce qui ne s’est pas produit, n’a pas, loin de là, que cette acception et qu’il se charge principalement, notamment dans son emploi temporel et non modal, d’une lecture en conditionnel présent de type futur des historiens. La seconde combinaison quant à elle, kāna sa‑yakūnu qad faʿala, permet alors logiquement d’exprimer le conditionnel passé, ce qui est le cas dans ses emplois modaux de même que dans son emploi temporel où elle est alors l’équivalent du futur antérieur des historiens. Surtout, ces deux combinaisons se présentent comme immédiatement repérables pour ce qu’elles sont, au contraire de formes plus classiques qui risquent souvent d’exposer à une première lecture en passé de forme ET de sens puis à une seconde pour restituer le sens conditionnel visé.
L’errance sacrée de ʿAbdallāh ibn Salām
Authors: Faü Jean‑François
Published: January 2020

Les sources musulmanes se sont intéressées à la conversion à l’islam de ʿAbdallāh ibn Salām, rabbin de Médine. Cependant, sa biographie reste limitée, et la majorité des sources s’articulent essentiellement autour de sa vie médinoise. En effet, aucun des ouvrages étudiés ne fait référence à son mausolée égyptien, si ce n’est une modeste publication en arabe mentionnant le mausolée de ʿAbdallāh ibn Salām, dans un village éponyme du delta du Nil. Cette figure émergeante du premier islam y fait toujours l’objet d’une vénération de la part de la population locale. Se pose ici la question du cheminement de la mémoire de ce premier juif converti à l’islam à Médine, en 622, après sa rencontre avec le Prophète Muḥammad, et de son errance sacrée qui mena sa mémoire cultuelle jusqu’à Timay al‑Amdīd.
Le sceau de la paix

Published: January 2020

La huitième et dernière croisade organisée par Louis IX en 669/1270 et dirigée contre Tunis se solde par la mort du roi ; elle aboutit à la conclusion d’une trêve de quinze ans entre son fils Philippe III, Charles d’Anjou et le sultan hafside al‑Mustanṣir, qui règle les conditions d’évacuation du territoire hafside. Le traité, qui nous est parvenu uniquement dans sa rédaction arabe, est muni d’un sceau exceptionnel, seul exemple connu de sceau pendant de souverain musulman. L’analyse diplomatique et codicologique du document met en évidence tout l’intérêt qu’il revêt dans l’étude des pratiques de la chancellerie hafside, et dévoile le processus de négociations, les conditions de rédaction et de ratification de l’ensemble des clauses de l’accord. Il s’agit néanmoins d’un document atypique, rédigé à la hâte dans des circonstances difficiles, par un non‑professionnel de la chancellerie, et dont les négociations ont été menées par un acteur diplomatique inattendu.

Published: January 2020

This article is an attempt to place the history of the Copts into a broader context, that of Ottoman history and shows that Coptic history is closely linked to Egyptian history. Based on two sharia court cases, we can explain not only the period of transformation in Coptic history but also the history of Egypt at the end of the 16th century, which completed at the middle of 17th century. On the other hand, the article shows how the sources of the courts can be supplemented with Coptic sources, and that to better understand the 17th century, it would be necessary to use both of these sources. The two court cases studied here are only comprehensible when Coptic sources are taken into consideration.
On Health Expenditure and Income Inequality
Authors: Torul Orhan
Published: January 2020

This study investigates the relationship between health care expenditure and income inequality empirically. Using data from a large panel of countries covering a sizeable period of time, how level and composition of health care expenditures correlate with income inequality is studied via the panel data fixed effects estimation methodology. These estimations yield several robust findings. First, there is a significant positive correlation between income inequality and reliance on private resources for health care financing. Second, there exists a significant negative correlation between health care expenditure per capita and income inequality. Third, there is a significant negative correlation between income inequality and health care expenditure as a share of GDP. Next, this study analyzes a select group of well-established democracies with developed economies to detect if health expenditure and income inequality variables correlate with public beliefs and preferences. Empirical analyses reveal that indeed belief and preferences accord well with policy choices.

Technological innovation has been a key driving force for economic growth, industrial development, and increasing welfare. Two dominant streams of theories as market-failure and system-failure oriented the domain to reach development economy objectives for countries. In this case, national innovation systems have been recognized by the rising understanding of systems of innovation. National Innovation Systems have been considered as complex and multi-faceted. Therefore, for overcoming this complexity and make it simplified analytically, in this chapter only the healthcare field has been examined by considering University Hospital cases. It is aimed to understand cognitive contribution of university hospitals to health innovation system by examining scientific publications. It is found that regional perspective should be applied to create more applicable policies.

Neutrophils are key effector cells that orchestrate inflammatory responses in the tumor microenvironment. Although neutrophil extracellular DNA traps (NETs) entrap and kill pathogens, they also contribute to chronic inflammation and cancer progression. Thyroid cancer (TC) is the most frequently occurring cancer of the endocrine system, accounting for 70% of deaths due to endocrine tumors. Although anaplastic TC (ATC) is rare among TCs, it is highly lethal. We demonstrated in a recent study that tumor-infiltrating neutrophil density correlated with TC size. Moreover, TC-derived soluble mediators modulate the human neutrophil phenotype. Our study aimed to investigate the involvement of NETs in human TC. Highly purified neutrophils from healthy donors were primed in vitro with a papillary TC or ATC cell line conditioned medium (CM) or with a normal thyroid CM as control. NET release was quantified using a High-Content Imaging System. Neutrophil viability was assessed by flow cytometry. Fluorescence microscopy, flow cytometry, and PCR were performed to determine the mitochondrial origin of ATC-induced NETs. ATC CM–primed neutrophils were cocultured with ATC cells to determine the effects exerted by NETs on cell proliferation. ATC CM induce NET release, whereas papillary TC or normal thyroid CM did not. ATC CM–induced NET production occurred in a reactive oxygen species–dependent and cell death–independent manner and was associated with mitochondrial reactive oxygen species production; the NETs contained mitochondrial DNA. ATC CM–primed neutrophils promoted ATC cell proliferation in a NET-dependent manner.
Complete androgen insensitivity syndrome with intra-abdominal seminoma in a phenotypic female

Published: January 2020

Androgen insensitivity syndrome (AIS) is a rare, X-linked recessive disorder which causes alterations in androgen receptor gene leading to hormone resistance, which may present clinically under three phenotypes: complete AIS (CAIS), partial AIS, or mild AIS. The symptoms range from phenotypically normal males with impaired spermatogenesis to phenotypically normal women with primary amenorrhea. We report a case of a 35-year-old woman who was diagnosed with CAIS and presented with malignant transformation of the undescended testis. The histopathology confirmed the presence of seminoma. In this case report, we reviewed the literature which describes the biochemical and endocrinological abnormalities leading to the syndrome. It also highlights the potential for malignant changes of the undescended testes, diagnosis, and therapeutic management.
Calvarial involvement in disseminated rhinosporidiosis – A case report and literature review
Authors: Dewangan B , Naik R , Membally R , Dewangan M
Published: January 2020

Rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi and mainly involves nasal and ocular mucosa. Bony involvement in rhinosporidiosis is very rare. A young male, previously operated for nasal rhinosporidiosis, presented with two bony swellings on the forehead and multiple subcutaneous lesions on the right lower limb. The diagnosis of disseminated cutaneous rhinosporidiosis with frontal bone involvement was made with the help of fine needle aspiration cytology (FNAC), histopathology, and computed tomography (CT) scan head. Wide excision of the bony lesion was performed. To the best of our knowledge, this is the first radiologically proven case of frontal bone involvement in disseminated rhinosporidiosis. Early diagnosis can be established with a good clinicopathological and radiological correlation. It also emphasizes the importance of CT scan for the evaluation of any subcutaneous skull lesion.

We report the clinical details, imaging findings, and management of a 74-year-old male who had recurrent episodes of massive hematemesis secondary to rupture of a cavernous internal carotid artery (ICA) aneurysm. Ruptured ICA aneurysms may present with epistaxis. However, intracranial aneurysmal rupture with hematemesis as the presenting complaint has not been described previously in the literature. In this case report we describe the pathophysiology of cerebral aneurysm as a cause of hematemesis and its management.
A cross-sectional study of alexithymia in patients with relapse remitting form of multiple sclerosis
Authors: Stojanov J , Stojanov A
Published: January 2020

Background:

Alexithymia is one's incapacity to identify, comprehend, and describe emotions. There is almost no literature data about the levels of alexithymia among patients with relapse remitting type of multiple sclerosis.

Aim:

The objective of the present study was to assess the levels of alexithymia in patients with relapse remitting type of multiple sclerosis in relation to their sociodemographic variables and clinical characteristics of the disease.

Methods:

This cross-sectional study included 106 consecutively assessed patients with relapse remitting type of multiple sclerosis. In addition to the data regarding disease duration, number of demyelinating relapses, and degree of neurological disability, assessed by the expanded disability scale score (EDSS), we used Toronto alexithymia scale (TAS), fatigue severity scale (FSS) and, Hamilton scale for the assessment of anxiety and depression and sociodemographic questionnaire.

Results:

Study included 74 female and 32 male patients, with a median age of 44 years, median disease duration 90 months, and median EDSS 4. About 29.55% of patients had alexithymia and borderline alexithymia was observed in 31.15% patients. Alexithymia correlated with anxiety and depression (P < 0.01) on all TAS subscales. Higher levels of neurological disability based on EDSS, severe fatigue based on FSS scores, and severe relapse remitting type of multiple sclerosis with more relapses and longer disease duration correlated with alexithymia (P < 0.01), depression (P < 0.01), and anxiety (P < 0.01). Higher rates of alexithymia were noticed in older, unemployed, single patients, and those having fewer children.

Conclusions:

Alexithymia was found in a relatively high percentage in patients with relapse remitting type of multiple sclerosis.
Polynomial monads and delooping of mapping spaces
Authors: Batanin Michael A. , De Leger Florian
Published: January 2020

We extend some classical results – such as Quillen’s Theorem A, the Grothendieck construction, Thomason’s theorem and the characterisation of homotopically cofinal functors – from the homotopy theory of small categories to polynomial monads and their algebras.

As an application we give a categorical proof of the Dwyer–Hess and Turchin results concerning the explicit double delooping of spaces of long knots.
Analysis of disaster resilience of urban planning facilities on urban flooding vulnerability
Authors: Park Kiyong , Oh Hoo , Won Jeong-hun
Published: January 2020

Rainfall continues to increase due to the influence of global warming and is resulting in an increase in flood damage. The purpose of this study is to propose an approach for reducing urban flood damage and improving urban resilience. Urban flooding vulnerability analysis used land use and building characteristics as evaluation indicators. Disaster resilience analysis of urban planning facilities focused on urban and spatial aspects. The results of these analyses were overlapped to analyze whether urban planning facilities were properly located in areas vulnerable to urban flooding. The result of mapping the two results showed that there are some urban planning facilities with low resilience in the Red Zone, the central commercial area of Changwon, which has the highest vulnerability. This zone should have the appropriate placement of high-resilience facilities, such as disaster prevention facilities and space facilities. This study proposes a method to minimize flood damage in urban space. This system can cope with and systematically manage flood damage by increasing disaster resilience through appropriate land use planning and site selection for urban planning facilities.
X80 Steel Corrosion Induced by Alternating Current in Water-Saturated Acidic Soil

Published: January 2020

X80 steel corrosion induced by alternating current (AC) had been investigated by surface analyses and electrochemical measurements in water-saturated acidic soils. The AC sharply increased the corrosion rate of X80 steel. Moreover, the DC potential of X80 steel shifted toward the negative direction after applying AC density, and decreased with the AC density ascending from 0 A/m2 to 200 A/m2. A power function model, CR = ain + b, was used to reflect the relation between AC density and corrosion rate. γ-FeOOH acting as an oxidizer weakened the protective ability of product film, and further accelerated the corrosion of steel.
The Unified Mechanism of Corrosion in Aqueous Weak Acids Solutions: A Review of the Recent Developments in Mechanistic Understandings of Mild Steel Corrosion in the Presence of Carboxylic Acids, Carbon Dioxide, and Hydrogen Sulfide
Authors: Kahyarian Aria , Brown Bruce , Nešić Srdjan
Published: January 2020

The recent developments in mechanistic understandings of mild steel corrosion in the presence of carboxylic acids, carbon dioxide, and hydrogen sulfide, when place side by side, reveal a simple, universal mechanism despite all the differences conventionally presumed for these corroding systems. These findings are recast into a generic mechanistic view of corrosion in aqueous weak acid solutions herein. In this mechanism, the buffering effect resulting from the chemical dissociation reaction inside the boundary layer, is highlighted as an inherent property of all weak acids. The validity of this mechanism was further examined through mathematical experimentation based on a comprehensive mechanistic model. It is shown that this mechanism is able to account for a wide range of characteristic behavior of cathodic currents, including those previously associated with the direct reduction reactions. The results are ultimately presented as a simple and generic categorization of weak acids based on their pKa values to serve as a basis to assess the detrimental effect of any weak acid on mild steel corrosion in aqueous acidic solutions.

A very high-resolution assessment and modelling of urban air quality
Authors: Wolf Tobias , Pettersson Lasse H. , Esau Igor
Published: January 2020

Abstract. Urban air quality is one of the most prominent
environmental concerns for modern city residents and authorities. Accurate
monitoring of air quality is difficult due to intrinsic urban landscape
heterogeneity and superposition of multiple polluting sources. Existing
approaches often do not provide the necessary spatial details and peak
concentrations of pollutants, especially at larger distances from monitoring
stations. A more advanced integrated approach is needed. This study presents
a very high-resolution air quality assessment with the Parallelized Large-Eddy Simulation Model (PALM), capitalising on local measurements. This fully three-dimensional
primitive-equation hydrodynamical model resolves both structural details of
the complex urban surface and turbulent eddies larger than 10 m in size. We
ran a set of 27 meteorological weather scenarios in order to assess the
dispersion of pollutants in Bergen, a middle-sized Norwegian city embedded
in a coastal valley. This set of scenarios represents typically observed
weather conditions with high air pollution from nitrogen dioxide (NO2)
and particulate matter (PM2.5). The modelling methodology helped to
identify pathways and patterns of air pollution caused by the three main
local air pollution sources in the city. These are road vehicle traffic,
domestic house heating with wood-burning fireplaces and ships docked in the
harbour area next to the city centre. The study produced vulnerability maps,
highlighting the most impacted districts for each weather and emission
scenario. Overall, the largest contribution to air pollution over inhabited
areas in Bergen was caused by road traffic emissions for NO2 and
wood-burning fireplaces for PM2.5 pollution. The effect of emission
from ships in the port was mostly restricted to the areas close to the
harbour and moderate in comparison. However, the results have contributed to
implementation of measures to reduce emissions from ships in Bergen harbour,
including provision of shore power.
