Constraining the Coronal Heights and Readjustment Velocities Based on the Detection of a Few Hundred Seconds Delays in the Z Source GX 17+2
Authors: Sriram K. , Malu S. , Choi C. S.
Published: September 2019

Neutron star Z-type sources provide a unique platform in order to understand the structure of accretion disk–corona geometry emitting close to the Eddington luminosity. Using RXTE and Nuclear Spectroscopic Telescope Array Mission (NuSTAR) satellite data, we performed crosscorrelation function (CCF) studies in GX 17+2 in order to constrain the size of the corona responsible for hard X-rays. From the RXTE data, we found that during horizontal and normal branches, the CCFs show anticorrelated hard (16–30 keV) and soft (2–5 keV) X-ray delays of the order of a few tens to hundred seconds with a mean correlation coefficient of 0.42 ± 0.11. Few observations shows correlated lags and, on one occasion, coincident with radio emission. We also report an anticorrelated hard X-ray delay of 113 ± 51 s using the NuSTAR data of GX 17+2. Based on RXTE data, we find that soft and hard X-ray fluxes are varying, indicating the changes in the disk–corona structure during delays. We bridle the size of the corona using relativistic precession, transition layer models, and boundary layer models. Assuming the delays to be a readjustment timescale of the disk–corona structure, the height of the corona was estimated to be ∼17–100 km. Assuming that the inner region of the truncated disk is occupied by the corona, we constrain the coronal readjustment velocities (v
corona = βv
disk, where v
disk is the radial velocity component of the disk) of the order of β = 0.06–0.12. This study indicates that the observed delays are primarily dependent on the varying coronal readjustment velocities.

We present the first results from the Small Magellanic Cloud portion of a new Australia Telescope Compact Array H i absorption survey of both of the Magellanic Clouds, comprising over 800 hr of observations. Our new H i absorption line data allow us to measure the temperature and fraction of cold neutral gas in a low-metallicity environment. We observed 22 separate fields, targeting a total of 55 continuum sources, against 37 of which we detected H i absorption; from this we measure a column-density-weighted mean average spin temperature of

 = 150 K. Splitting the spectra into individual absorption line features, we estimate the temperatures of different gas components and find an average cold gas temperature of ∼30 K for this sample, lower than the average of ∼40 K in the Milky Way. The H i appears to be evenly distributed throughout the SMC, and we detect absorption in 67% of the lines of sight in our sample, including some outside the main body of the galaxy (N
H i

cm−2). The optical depth and temperature of the cold neutral atomic gas show no strong trend with location spatially or in velocity. Despite the low-metallicity environment, we find an average cold gas fraction of ∼20%, not dissimilar from that of the Milky Way.
Myth in 300 Strokes
Mit v 300 taktih

Authors: Pobežin Gregor , Grdina Igor
Published: September 2019

This paper aims to explore the phenomenon of the opera minute which emerged from the avant-garde experimentalism after WWI; its beginner and one of the foremost masters, the French composer Darius Milhaud put three short, eight-minute operas on stage in 1927. Others soon followed, among them the Slovenian composer Slavko Osterc who composed the opera-minute “Medea” in 1932. This paper is the first to transcribe in length the manuscript of Osterc’s “Medea”, comparing it to Euripides’ original. Furthermore, the article aims to establish the fine similarities and distinctions between the approach regular opera took towards myth and that of the avant-garde opera-minute.
Bilan en 1977 des recherches archéologiques à Tegdaoust et Koumbi Saleh (Mauritanie)
Authors: Robert-Chaleix Denise , Robert Serge , Saison Bernard
Published: September 2019

Les auteurs, qui ont organisé et conduit les missions de recherche archéologique sur les sites de Tegdaoust, Koumbi Saleh et Azougui présentent ici, dans un article écrit en 1977, une vision d’ensemble –fondée sur la pratique de terrain– de la recherche sur les sites médiévaux à cette époque. Ce texte, antérieur à la soutenance des nombreuses thèses sur Tegdaoust et à celle sur Koumbi Saleh, reste au plus près des données immédiates du terrain apportées par des chantiers qui fonctionnaient de manière synchrone. Cette vision « horizontale » nous place ainsi au cœur de la construction du savoir propre à chaque site, transcrit les pistes de recherches suggérées par la fouille, l’effort d’harmonisation, de corrélation entre les zones fouillées, propre à chacun des grands sites. Elle évite ausssi le biais personnel apporté par les thèses –qui ont « naturellement » tendance à survaloriser l’objet même de la thèse– qui lui ont succédé. Des données archéologiques précises sur la grande mosquée de Koumbi Saleh et sur ses rapports avec le quartier environnant sont, pour la première fois, rendues publiques.
Deubiquitinating Enzyme UCH-L1 Promotes Dendritic Cell Antigen Cross-Presentation by Favoring Recycling of MHC Class I Molecules

The deubiquitinating enzyme ubiquitin C-terminal hydrolase-L1 (UCH-L1) is required for the maintenance of axonal integrity in neurons and is thought to regulate the intracellular pool of ubiquitin in the brain. In this study, we show that UCH-L1 has an immunological function in dendritic cell (DC) Ag cross-presentation. UCH-L1 is expressed in mouse kidney, spleen, and bone marrow–derived DCs, and its expression and activity are regulated by the immune stimuli LPS and IFN-γ. UCH-L1–deficient mice have significantly reduced ability to cross-prime CD8 T cells in vivo and in vitro because of a reduced ability of DCs to generate MHC class I (MHC I) peptide complexes for cross-presented Ags. Mechanistically, Ag uptake by phagocytosis and receptor-mediated endocytosis as well as phagosome maturation are unaffected by loss of UCH-L1 in DCs. Rather, MHC I recycling is reduced by loss of UCH-L1, which affects the colocalization of intracellular MHC I with late endosomal/lysosomal compartments necessary for cross-presentation of Ag. These results demonstrate a hitherto unrecognized role of the deubiquitinating enzyme UCH-L1 in DC Ag processing.
LSD1 Cooperates with Noncanonical NF-κB Signaling to Regulate Marginal Zone B Cell Development
Authors: Haines Robert R. , Scharer Christopher D. , Lobby Jenna L. , Boss Jeremy M.
Published: September 2019

Marginal zone B cells (MZB) are a mature B cell subset that rapidly respond to blood-borne pathogens. Although the transcriptional changes that occur throughout MZB development are known, the corresponding epigenetic changes and epigenetic modifying proteins that facilitate these changes are poorly understood. The histone demethylase LSD1 is an epigenetic modifier that promotes plasmablast formation, but its role in B cell development has not been explored. In this study, a role for LSD1 in the development of B cell subsets was examined. B cell–conditional deletion of LSD1 in mice resulted in a decrease in MZB whereas follicular B cells and bone marrow B cell populations were minimally affected. LSD1 repressed genes in MZB that were normally upregulated in the myeloid and follicular B cell lineages. Correspondingly, LSD1 regulated chromatin accessibility at the motifs of transcription factors known to regulate splenic B cell development, including NF-κB motifs. The importance of NF-κB signaling was examined through an ex vivo MZB development assay, which showed that both LSD1-deficient and NF-κB–inhibited transitional B cells failed to undergo full MZB development. Gene expression and chromatin accessibility analyses of in vivo– and ex vivo–generated LSD1-deficient MZB indicated that LSD1 regulated the downstream target genes of noncanonical NF-κB signaling. Additionally LSD1 was found to interact with the noncanonical NF-κB transcription factor p52. Together, these data reveal that the epigenetic modulation of the noncanonical NF-κB signaling pathway by LSD1 is an essential process during the development of MZB.

Four dimensional topological quantum field theories from $G$-crossed braided categories
Authors: Cui Shawn X.
Published: September 2019

We construct a state-sum type invariant of smooth closed oriented 4-manifolds out of a

G

-crossed braided spherical fusion category (

G

-BSFC) for

G

a finite group. The construction can be extended to obtain a

(3+1)

-dimensional topological quantum field theory (TQFT). The invariant of 4-manifolds generalizes several known invariants in literature such as the Crane–Yetter invariant from a ribbon fusion category and Yetter's invariant from homotopy 2-types. If the

G

-BSFC is concentrated only at the sector indexed by the trivial group element, a cohomology class in

H^4(G,U(1))

can be introduced to produce a different invariant, which reduces to the twisted Dijkgraaf–Witten theory in a special case. Although not proven, it is believed that our invariants are strictly different from other known invariants. It remains to be seen if the invariants are sensitive to smooth structures. It is expected that the most general input to the state-sum type construction of

(3+1)

-TQFTs is a spherical fusion 2-category. We show that a

G

-BSFC corresponds to a monoidal 2-category with certain extra structure, but that structure does not satisfy all the axioms of a spherical fusion 2-category given by M. Mackaay. Thus the question of what axioms properly define a spherical fusion 2-category is open.

Toward an open access to high-frequency lake modeling and statistics data for scientists and practitioners – the case of Swiss lakes using Simstrat v2.1
Authors: Gaudard Adrien , Råman Vinnå Love , Bärenbold Fabian , Schmid Martin , Bouffard Damien
Published: September 2019

Abstract. One-dimensional hydrodynamic models are nowadays widely recognized as key
tools for lake studies. They offer the possibility to analyze processes at
high frequency, here referring to hourly timescales, to investigate
scenarios and test hypotheses. Yet, simulation outputs are mainly used by
the modellers themselves and often not easily reachable for the outside
community. We have developed an open-access web-based platform for
visualization and promotion of easy access to lake model output data updated
in near-real time (http://simstrat.eawag.ch, last access: 29 August 2019). This platform was developed for 54
lakes in Switzerland with potential for adaptation to other regions or at
global scale using appropriate forcing input data. The benefit of this data
platform is practically illustrated with two examples. First, we show that
the output data allows for assessing the long-term effects of past climate
change on the thermal structure of a lake. The study confirms the need to
not only evaluate changes in all atmospheric forcing but also changes in the
watershed or throughflow heat energy and changes in light penetration to
assess the lake thermal structure. Then, we show how the data platform can
be used to study and compare the role of episodic strong wind events for
different lakes on a regional scale and especially how their thermal
structure is temporarily destabilized. With this open-access data platform,
we demonstrate a new path forward for scientists and practitioners promoting
a cross exchange of expertise through openly sharing in situ and model
data.
Recurrent Idiopathic Subglottic Stenosis in Multiple Pregnancies: A Case Report
Authors: Shao Fei Fei
Published: September 2019

Introduction: Idiopathic subglottic stenosis (ISS) is a type of central airway obstruction primarily affecting adult Caucasian females. Its rarity and similar clinical presentation to asthma contribute to its frequent misdiagnosis. Timely treatment of ISS is crucial for pregnant patients who are at risk for emergent surgeries necessitating ventilation and intubation.

Case: A 29-year-old, previously healthy female reported new onset dyspnea on exertion and a dry, non-productive cough to her family physician. Clinical exam was unremarkable; however, pulmonary function testing revealed a moderate, fixed airway obstruction. Endoscopy visualized subglottic stenosis 1.7 cmdistal to her vocal cords and surgical intervention using CO2 laser dilatation was scheduled with Otolaryngology. However, the patient received a positive pregnancy test prior to her elective surgery dateand after consideration of risks and benefits to mother and fetus, the surgery was postponed to her second trimester. Unfortunately, the patient miscarried her fetus and was scheduled for an emergent dilatation and curettage (D&C). She was successfully bag-mask ventilated during the D&C and subsequently underwent surgery for ISS with full resolution of her symptoms. In subsequent follow-up, the patient reported a return of dyspnea coinciding with another positive pregnancy test. ISS recurrence was diagnosed; however, as symptoms were mild, a repeat surgery was postponed until the patient safely delivered her child.

Discussion: This case illustrates the difficulties in the diagnosis and management of ISS in pregnant patients during their childbearing years as surgical intervention will impact both the mother and fetus.
Work Related Open Globe Injury
Authors: Kamala Lakshmi
Published: September 2019

Traumatic open globe injuries are a leading cause of blindness/visual impairment in the world. A significant number of reported open globe injuries occur at the workplace and have been historically associated with non-compliance with workplace safety guidelines and not wearing eye related personal protective equipment (PPE). In this case report, we describe a 27-year-old man’s workplace related open globe injury despite wearing PPE. We explore the prognostic factors in determining final visual acuity and do a literature review of case reports with good outcomes despite poor initial prognostication in severe open globe injuries. The option of enucleation and its common indications are discussed. We also examine the factors determining patient satisfaction with ocular prosthesis along with an assessment of the role of PPEs in workplace related ocular trauma.

Published: September 2019

O objetivo do estudo é caracterizar os modos como os corpos com deficiência e as questões de diversidade e inclusão se apresentam nas narrativas das HQs de Maurício de Sousa. Adota-se a análise semiótica como perspectiva metodológica para abordar criticamente as questões sobre deficiência nas HQs. Verifica-se que os personagens com deficiência foram inseridos nas narrativas e interagiram com os demais personagens, sendo incluídos no meio social. As deficiências são tratadas a partir de uma abordagem social, com ênfase para questões da acessibilidade e preconceitos, em detrimento de um olhar para suas limitações para a vivência da infância. O respeito às diferenças e o reforço às qualidades dos colegas com deficiência foram valores recorrentes nos discursos analisados nas HQs.
From Stage to Live Broadcasts and Streaming: O'Neill's Theatre Guild Model in the Digital Age
Authors: McGovern Dan
Published: September 2019

In 1929 Eugene O'Neill expressed the hope that something like the Theatre Guild would emerge for the new “talkies.” This article traces the history of efforts to realize that dream, that is, to present film adaptations of stage plays in curated series for discerning audiences. First, the Theatre Guild's own efforts to present adaptations of stage plays for radio and television audiences are chronicled, next the ambitious but short-lived American Film Theatre subscription series, and finally plays filmed for broadcasting by National Theatre Live and streaming by BroadwayHD. In particular, the article focuses on artistic and commercial challenges the Geffen Playhouse in Los Angeles faced when in 2017 it partnered with BroadwayHD to film and livestream its production of O'Neill's Long Day's Journey Into Night. The common aesthetic objections to filmed plays are considered as is the concern that they may undercut the audience for live theatre.
Microparameters and language variation
Authors: Li Yen-hui Audrey , Wei Wei Haley
Published: September 2019

Due to issues with macroparameters, much work has turned to identifying microparameters (generally feature specifications in the Lexicon). This line of research often focuses on the comparison of dialects or comparison among the varieties of closely related language families. Baker (2008) questions the sufficiency of focusing on such microparametric syntax. This paper shows that even within the varieties of a single language family (Chinese), the reliance on lexical feature specifications (microparameter) could miss opportunities for discovering more fundamental and principled factors underlying cross-linguistic differences. Indeed, some of such differences analyzed in terms of microparameters should be re-considered from the prosodic perspective. Our focus will be on a number of microparameters proposed by Huang (2014) as converging to an analyticity vs. syntheticity macroparameter, building on differences among diachronic and synchronic varieties in the Chinese language family. This paper shows that the relevant empirical claims are not confirmed when a broader range of data is investigated. Importantly, the analyses proposed in terms of microparameters mask more adequate accounts for the differences, with prosodic variation playing a role.
La participación social en la escuela en México: ¿un problema de democracia y cultura política?
Authors: Flores-Crespo Pedro
Published: September 2019

Este artículo cuestiona la tesis culturalista para explicar porqué la participación social no ha podido surgir enel sector educativo de México. Basado en un trabajo empírico con escuelas secundarias de tres estados: Chiapas, Ciudad de México y Durango (n=27), este trabajo muestra que los individuos sí muestran predisposición a intervenir de manera crítica y razonada en sus centros escolares, no obstante, no existen las estructuras de oportunidad para ampliar competencias ciudadanas, esos mismos actores no parecen verse como iguales y hay entendimiento superficial del mundo juvenil por parte de los maestros que impiden que la participación del ciudadano se despliegue, pese al régimen autoritario construido por el sistema de partido único (1920-2000).
La competencia extraterritorial de las municipalidades: el caso CARES

Según la doctrina clásica, los municipios solo pueden actuar válidamente dentro de su territorio. Sin embargo, la Contraloría General de la República ha resuelto la validez de actuaciones en comunas distintas. El autor argumenta que existen tres tipos de actuaciones validadas: cuando existiere normativa especial, cuando las actuaciones no impliquen el desempeño de funciones de otras municipalidades u otros órganos del Estado, y cuando cumpla funciones municipales como la promoción del desarrollo comunitario. Uno de estos casos es revisado minuciosamente, sobre la instalación y administración de hogares estudiantiles fuera de la extensión de la comuna, en que el autor fuere su asesor legal.
Publicidad de votos, concurrencias y disidencias en las sentencias del Tribunal Constitucional chileno: un análisis crítico
Authors: Orellana Ramos Edison Patricio
Published: September 2019

La regulación sobre el modo en que el Tribunal Constitucional chileno toma sus decisiones, es decir, las reglas jurídicas acerca de cómo las sentencias deben ser producidas, implica que los miembros de dicho tribunal están obligados a votar acerca de la parte resolutiva de la sentencia y de sus fundamentos; que sus votos, disidencias y concurrencias deben expresarse en las sentencias, y que dichas disidencias y concurrencias deben expresarse nominalmente, indicando los nombres de quiénes concurren a la opinión mayoritaria y minoritaria. A partir de un concepto de legitimidad de los tribunales constitucionales basado en la independencia y neutralidad de los mismos en el contexto de una democracia constitucional, se ofrece un análisis crítico de los efectos que estas tres reglas combinadas producen, en cuanto afectan la legitimidad del Tribunal Constitucional chileno a través de la creación de incentivos hacia una excesiva personalización de sus decisiones y la defensa de posiciones extremas por parte de sus miembros.
Inovação no ensino do Direito. Se resume às TIC?
Authors: Cicero Nidia Karina
Published: September 2019

O ensino jurídico é convocado à reforma. E esta necessidade imperiosa de renovação refere-se não apenas aos conteúdos curriculares que devem ser atualizados constantemente e periodicamente, mas também, e principalmente, às formas de ensinar e aprender as ciências jurídicas. Algumas experiências em sala de aula que foram colocadas em prática e relacionadas neste ensaio refletem plenamente que as TICs são ideais para gerar inovação educacional, mas também defendo que esta última não se desenvolve pela mera incorporação das TIC às práticas de ensino. Neste artigo concluo que é necessário repensar as abordagens metodológicas das ciências jurídicas, a fim de aproximá-las do novo perfil dos estudantes e dos profissionais da área jurídica requeridos pela sociedade da informação em que vivemos.

El tema de investigación se centra en las condiciones de vida y estrategias familiares de trabajo de los cortadores de café en Yalí (2016-2017). El método utilizado para la recopilación de la información durante el proceso de investigación fue la etnografía. Se analizaron y se describieron con detalle todos y cada uno de los componentes de la vida cotidiana de los cortadores de café. El periodo de cosecha se da una vez por año, con una duración entre dos a tres meses, tiempo en que familias enteras se involucran en las labores de corte de café porque es su principal fuente de ingreso al año. El caso de los cortadores de café se ve reflejado como una realidad compleja, vinculada primeramente con los indicadores macroeconómicos, y posteriormente se realiza una aproximación al estudio de sus condiciones de vida en el trabajo durante las temporadas de corte de café. La condición socioeconómica de los cortadores tiene como punto de partida el ingreso que oscila entre 6,000 a 7,000 córdobas mensuales, estos deben ajustarse a los períodos de cese del corte de café. En cuanto a la situación alimentaria, la ingesta está en basada en dos tipos de alimentos: frijoles y maíz. Por otro lado, la vivienda está construida con materiales perecederos, y en los períodos de corte de café viven en los campamentos de las fincas. Además, el nivel educativo está entre primaria incompleta y completa. Finalmente, la estrategia familiar consiste en involucrar a toda la familia para la reproducción social de la misma.

EFEITOS DA MUDANÇA DO USO DA TERRA SOBRE A VAZÃO MÁXIMA NO CÓRREGO MATILDE-CUÊ, MARECHAL CÂNDIDO RONDON, PARANÁ
Authors: Quinonez Fernandez Oscar Vicente
Published: September 2019

O objetivo do trabalho é estudar a variação temporal da vazão máxima no córrego Matilde-cuê que drena a área urbana de Marechal Cândido Rondon, Oeste do Paraná. O método empregado é o Ven Te Chow – Soil Conservation Service (SCS), um modelo hidrológico de transformação de chuvas em vazões. As vazões máximas foram simuladas para condições normais de umidade (NII) em dois cenários: período pré-colonização (1950 com floresta nativa ainda intacta) e período recente (2013 com retirada total da floresta nativa e predomínio da agricultura e urbanização). As vazões foram estimadas para diversos tempo de duração da chuva e tempo de retorno da precipitação de 2, 5, 10 e 20 anos. A área de drenagem da bacia é de 6,165 km2 e em 2013, a área urbanizada alcançou de 64,3%, áreas agrícolas 24,5%, pastagens 2,2% e a vegetação 9%. Os resultados mostram expressivo aumento da vazão máxima nos dois períodos analisados: s vazões máximas para precipitações com Tr=2 anos aumentou 103% e para Tr=20 anos cresceu 66,8%. As precipitações curtas e frequentes geraram maior aumento porcentual da vazão máxima do que chuvas prolongadas e infrequentes.

Effects of the Coating Mixture on the Penetration of Liquids into Paper
Authors: Leks-Stępień Janina
Published: September 2019

The pigment coating of paper is usually performed to enhance the physical properties of paper and its printability. The coating generally makes paper whiter, brighter and more opaque. The properties of the coated paper depend, among others, on the porous structure of the coating developed, which is determined by the pigments, binders and their reactions. The influence of the type and quantity of coating components and ink absorption into the coating layer was studied in this work. Printing ink penetration was measured using a Penetration Dynamic Analyser with an HVL module (High Viscous Liquid). The evenness of liquid penetration into paper was measured using a Penetration Dynamic Analyser with a PEA module (Print Evenness Analyser). Results obtained indicate that all three variables – coating pigment type, latex dose and ink type – may have an equally strong influence on liquid and ink penetration,and thus on print quality.

Educational Technology: Relevance to a Fijian Classroom
Authors: Gani Reginald , Devi Sharika , Goundar Sam , Reddy Emmenual , Saber Fatemeh
Published: September 2019

Educational technology has emerged as a necessary tool for classrooms in the developing world. Educational technology is the considered implementation of appropriate tools, techniques, or processes that facilitate the application of senses, memory, and cognition to enhance teaching practices and improve learning outcomes. It is defined as “the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources.” This research intends to identify educational technologies that are popular around the world and elaborate upon them. The research project further used a case study to sample schools in Fiji to determine their use of educational technologies in the Fijian classroom. Various uses, benefits, implementations, and challenges were identified together with the limitations of how educational technologies’ relevance to the Fijian classroom could be affected. The findings indicate that the Fijian classroom is not quite ready to completely embrace educational technologies into their operations given the challenges are few but immense. Questions suggesting future activities were also identified.
„Das ubersinnliche Substrat aller seiner Vermogen“
Authors: Bunte Martin ,   Editions Rodopi
Published: September 2019

This paper examines the underdetermined relation between the absolute and absolute knowledge. Fichte not only claimed that he provided the correct reading of Kant’s critical philosophy but also that his Wissenschaftslehre constructively addressed and resolved its systematic problems. By discussing Kant’s notion of a “transcendental substrate” and its relation to the “thing-in-itself” it will be shown that this claim has to be taken seriously even from a Kantian standpoint. Moreover, it will be shown that Fichte's critical assessment of Kant's philosophy at the beginning of his second private lecture on the Wissenschaftslehre given in Berlin in 1804 and his philosophical reflection of the highest principle of all knowing and its relation to the absolute can be understood as a solution to problems that historically originated with Kant and were left unsettled by him.
„ Der Freiheit ergiebt sich die Wahrheit “
Authors: Adler Anthony Curtis ,   Editions Rodopi
Published: September 2019

The inquiry into the nature of truth plays an important role in Fichte's thought, especially following his departure from Jena, and indeed in the WL-1804-ii the doctrine of truth emerges as the centerpiece of the WL. The following paper argues that the conception of truth evolves significantly after the WL-1804-ii, and that, in such texts as the Erlanger Metaphysik, the Spekulation zu Koppenhagen, and the 1812 WL, Fichte, building on the account of the hiatus in the WL-1804-ii while moving away from its notion of absolute truth, seeks to understand truth in terms of freedom, or indeed, as what »yields to freedom«, wherein freedom, through the negativity of the concept, produces an emptiness, a clearing, that is »fulfilled« with truth. Anticipating the phenomenological account of truth yet without abandoning a strong sense of normativity, Fichte’s alethology remains a compelling alternative to contemporary positions.

“Gay Is Good”: Digital collections in LGBTQ U.S. History
Authors: Johnston Lisa N.
Published: September 2019

June 28, 2019, was the 50th anniversary of the first day of the Stonewall Uprising. In the early morning hours, a series of spontaneous protests began at the Stonewall Inn following a police raid. Just over one year later, on July 1, 1970, librarian Israel Fishman organized the first meeting of the ALA Task Force on Gay Liberation at the ALA Annual Conference in Detroit. A few months later, activist Barbara Gittings, created the organization’s first “Gay Bibliography,” complete with the “Gay Is Good” slogan she adopted from her friend, Washington, D.C. activist, Franklin Kameny. She distributed 3,000 copies at the ALA Annual Conference in 1971. Gittings knew from experience the challenges of researching the history of sexual minorities.

Análise da vegetação secundária em unidades de conservação: o uso de recursos florestais por comunidades tradicionais
Authors: Gonçalves Danielly Caroline Miléo , Corrêa Jéssica Ariana de Jesus , Gama João Ricardo Vasconcellos , Oliveira Júnior Raimundo Cosme de
Published: September 2019

A florestas secundárias são fonte de recursos florestais para as populações tradicionais. Portanto, o objetivo do estudo é analisar a distribuição espacial da vegetação secundária na APA de Aramanaí e na comunidade de Maguari, na FLONA Tapajós, avaliando o potencial dessas áreas em fornecer espécies uteis, com destaque, a utilização de sementes florestais, para confecção de bijuterias pelos comunitários de Maguari. Foram realizadas entrevistas com os artesãos em Maguari, sobre a utilização de espécies florestais e posteriormente foi analisado a distribuição espacial dessa vegetação através do mapeamento do TerraClass, de uso e cobertura da terra dessas UCs. As principais espécies vegetais apontadas nas entrevistas foram o morototó (Schefflera morototoni (Aubl.) Maguire, Steyerm. & Frodin), o tento vermelho (Ormosia arborea L. /Adenanthera pavonina L.), tento amarelo (Ormosia excelsa Beth), saboneteira (Sapindus saponaria L.), jutaí (Hymenaea courbaril L.), tucumã (Astrocaryum aculeatum G.F.W Meyer) e o caracaxá ou jupati (Raphia taedigera Mart.), destacando o morototó como a semente mais utilizadas por todos os entrevistados. Foi apontado, através do estudo de distribuição espacial, o agrupamento da população do morototó em áreas de vegetação secundárias, que corresponde cerca de 17% das duas UCs, demonstrando que a população da região utiliza as espécies uteis de áreas de vegetação secundária. A vegetação secundária se tornou uma fonte de recursos florestais paras as comunidades inseridas em UCs. Dessarte, é importante para economia das comunidades e ao mesmo tempo, promove a preservação da vegetação primária do desmatamento, sendo uma forma de conservar a floresta e o estoque de recursos para as gerações futuras.

Published: September 2019

Aim. Preparation of aseptic seedlings Salvia hispanica L., callus initiation in vitro and establishment of primary explants suitable for the callus production. Methods. Seeds are sprouted on our own modification of conventional methods. The non-hormonal Murashige-Skoog agarized nutrient medium was used as basic medium for the experiments. Parts of one-month seedlings (roots, hypocotyl, cotyledon leaves) were used as explants for the use of the colza. We added growth regulators (BAP, 2,4-D) in different concentration combinations into the nutrient medium for callus initiation. Statistical processing was performed in Microsoft Office Excel. Results. Aseptic S. hispanica seedlings have been obtained. The callus growth was initiated on all types of explants, the dependence of the callus intensity on the type of explants and the growth regulators content in the nutrient medium was established. Morphogenic callus and root-regenerants have been obtained. Conclusions. Hypocotyl was the most suitable primary explant for callus growth. Seedlings, leaves and roots showed low morphogenetic capacity. The nutrient medium with an elevated 2,4-D content was the most effective for initiation of callus genesis and proliferation of non-morphogenous callus. A high concentration of 2,4-D in the medium improves S. hispanica callus growth but suppresses its morphogenic ability.Keywords: Salvia hispanica (Chia), in vitro culture, callus.

Regulation of Eag1 gating by its intracellular domains
Authors: Whicher Jonathan R , MacKinnon Roderick
Published: September 2019

Voltage-gated potassium channels (Kvs) are gated by transmembrane voltage sensors (VS) that move in response to changes in membrane voltage. Kv10.1 or Eag1 also has three intracellular domains: PAS, C-linker, and CNBHD. We demonstrate that the Eag1 intracellular domains are not required for voltage-dependent gating but likely interact with the VS to modulate gating. We identified specific interactions between the PAS, CNBHD, and VS that modulate voltage-dependent gating and provide evidence that VS movement destabilizes these interactions to promote channel opening. Additionally, mutation of these interactions renders Eag1 insensitive to calmodulin inhibition. The structure of the calmodulin insensitive mutant in a pre-open conformation suggests that channel opening may occur through a rotation of the intracellular domains and calmodulin may prevent this rotation by stabilizing interactions between the VS and intracellular domains. Intracellular domains likely play a similar modulatory role in voltage-dependent gating of the related Kv11-12 channels.
A common Salmonella Enteritidis sequence type from poultry and human gastroenteritis in Ibagué, Colombia
Authors: Fandiño Luz Clemencia , Verjan Noel
Published: September 2019

Introducción. Salmonella Enteritidis es una de las mayores causas de salmonelosis en el mundo, siendo los huevos contaminados y la carne de pollo cruda sus principales fuentes de infección. En Ibagué, Colombia, se identificaron los principales serovares circulando en granjas, superficies de huevos y canales de pollo, sin embargo, se desconoce si esos serovares son responsables de gastroenteritis.

Objetivo. Evaluar la relación genética entre aislamientos de Salmonella Enteritidis de aves de corral y humanos con gastroenteritis mediante multilocus sequence typing (MLST).

Materiales y métodos. Se aisló Salmonella spp., de casos clínicos de gastroenteritis (n=110). Se realizó test de sensibilidad antibiótica, seguido de serotipificación y tipificación por medio de MLST y se comparó S. Enteritidis de humanos frente a S. Enteritidis de granjas ponedoras y de huevo comercializado (n=6).

Resultados. Se aislaron 10 cepas de Salmonella spp., a partir de heces de humanos con gastroenteritis. Se obtuvo una prevalencia de Salmonella spp. de 9.09%, siendo S. Enteritidis (n=4), S. Typhymurium (n=2), S. Newport (n=1), S. Grupensis (n=1), S. Uganda (n=1) y S. Braenderup (n=1) los serotipos presentes en pacientes con gastroenteritis. El MLST indico que un tipo de secuencia común (ST11) de S. Enteritidis estuvo presente en todas las tres fuentes y mostraron el mismo patrón de resistencia antibiótica.

Conclusión. S. Enteritidis ST11 constituye un vínculo entre el consumo/manipulación de huevos contaminados y gastroenteritis humana en Ibagué. Son necesarios estudios complementarios para conocer si otros serovares de Salmonella aislados de carne de pollo cruda también se asocian con la gastroenteritis humana.
