Abstract
We report comprehensive multi-wavelength observations of a peculiar Type Ia-like supernova (“SN Ia-pec”) ASASSN-15pz. ASASSN-15pz is a spectroscopic “twin” of SN 2009dc, a so-called “Super-Chandrasekhar-mass” SN, throughout its evolution, but it has a peak luminosity

that is

dimmer and comparable to the SN 1991T sub-class of SNe Ia at the luminous end of the normal width-luminosity relation. The synthesized 56Ni mass of

is also substantially less than that found for several 2009dc-like SNe. Previous well-studied 2009dc-like SNe have generally suffered from large and uncertain amounts of host-galaxy extinction, which is negligible for ASASSN-15pz. Based on the color of ASASSN-15pz, we estimate a host extinction for SN 2009dc of

and confirm its high luminosity (

). The 2009dc-like SN population, which represents ∼1% of SNe Ia, exhibits a range of peak luminosities, and do not fit onto the tight width-luminosity relation. Their optical light curves also show significant diversity of late-time (≳50 days) decline rates. The nebular-phase spectra provide powerful diagnostics to identify the 2009dc-like events as a distinct class of SNe Ia. We suggest referring to these sources using the phenomenology-based “2009dc-like SN Ia-pec” instead of “Super-Chandrasekhar SN Ia,” which is based on an uncertain theoretical interpretation.
Prospects for Detecting X-Ray Polarization in Blazar Jets

Published: July 2019

Abstract
X-ray polarization should provide new probes of magnetic field geometry and acceleration physics near the base of blazar jets, but near-future missions will have limited sensitivity. We thus use existing lower energy data and X-ray variability measurements in the context of a basic synchro-Compton model to predict the X-ray polarization level and the probability of detection success for individual sources, listing the most attractive candidates for an Imaging X-ray Polarimetry Explorer campaign. We find that, as expected, several high-peak blazars such as Mrk 421 can be easily measured in 100 ks exposures. Most low-peak sources should only be accessible to triggered campaigns during bright flares. Surprisingly, a few intermediate peak sources can have anomalously high X-ray polarization and thus are attractive targets.

Abstract
The dependence of the polarization fraction p on total intensity I in polarized submillimeter emission measurements is typically parameterized as p ∝ I
−α
(α ≤ 1) and used to infer dust grain alignment efficiency in star-forming regions, with an index α = 1 indicating near-total lack of alignment of grains with the magnetic field. In this work, we demonstrate that the non-Gaussian noise characteristics of the polarization fraction may produce apparent measurements of α ∼ 1 even in data with significant signal-to-noise in Stokes Q, U, and I emission, and so with robust measurements of polarization angle. We present a simple model demonstrating this behavior and propose a criterion by which well-characterized measurements of the polarization fraction may be identified. We demonstrate that where our model is applicable, α can be recovered by fitting the p–I relationship with the mean of the Rice distribution without statistical debiasing of the polarization fraction. We apply our model to JCMT BISTRO Survey POL-2 850 μm observations of three clumps in the Ophiuchus molecular cloud, finding that in the externally illuminated Oph A region, α ≈ 0.34, while in the more isolated Oph B and C, despite their differing star formation histories, α ∼ 0.6–0.7. Our results thus suggest that dust grain alignment in dense gas is more strongly influenced by the incident interstellar radiation field than by star formation history. We further find that grains may remain aligned with the magnetic field at significantly higher gas densities than has previously been believed, thus allowing investigation of magnetic field properties within star-forming clumps and cores.

Published: July 2019

Abstract
Controlling portal vein pressure in living-donor liver transplantation has received increased attention owing to its potential importance for graft survival. Portal hypertension may lead to the activation of liver-resident APCs, including liver sinusoidal endothelial cells (LSECs), which have immunological tolerogenic capacity. We investigated the effects of portal hypertension on graft survival and the antidonor immune response using clinical data and a mouse model. We categorized patients (n = 136) according to their portal vein pressure values at the end of surgery. Using propensity score-matching analyses, we found that portal hypertension was significantly associated with a higher antidonor immune response and incidence of acute rejection. To investigate the mechanism, we performed an allogeneic coculture assay using a 70% hepatectomized (HTx) mouse model with or without a portosystemic shunt. Liver cells from HTx mice without a shunt exhibited a significantly greater anti-BALB/c B6 T cell response than those from sham-operated mice or HTx mice with a shunt. LSECs from sham-operated mice, but not from HTx mice, suppressed the B6 T cell alloresponse in a dose-dependent manner. Furthermore, LSECs from HTx mice without a shunt showed significantly downregulated MHC class I/II and programmed death-ligand 1 expression, and those from mice with a shunt showed recovered expression of these molecules. Postoperative portal hypertension enhances alloimmune responses in recipients after living-donor liver transplantation, likely due, in part, to the impaired immune-suppression capacity of LSECs.
Myeloid-Derived Suppressor Cells Confer Infectious Tolerance to Dampen Virus-Induced Tissue Immunoinflammation
Authors: Sarkar Roman , Mathew Amal , Sehrawat Sharvan 
Published: July 2019

Abstract
In this study, we investigated the response of myeloid-derived suppressor cells (MDSCs) during the pathogenesis of an immunoblinding disease of the cornea caused by HSV type 1 infection. We also measured the anti-inflammatory potential of in vitro–differentiated MDSCs in dampening herpetic stromal keratitis resulting from primary ocular HSV1 infection in mice. In the lymphoid organs and inflamed corneal tissues, MDSCs were phenotypically characterized as CD11b+Gr1lo-int cells. Sorted CD11b+Gr1lo-int cells, but not CD11b+Gr1hi cells, suppressed the proliferation and cytokine production by stimulated CD4+ T cells. In vitro–generated MDSCs inhibited the activity of stimulated CD4+ T cells in a predominantly contact-dependent manner. An adoptive transfer of in vitro–generated MDSCs before or after ocular HSV1 infection controlled herpetic stromal keratitis lesions. The transferred MDSCs were primarily recovered from the lymphoid organs of recipients. Surprisingly, MDSCs recipients expanded their endogenous Foxp3+ regulatory T cells (Tregs). We further demonstrated the MDSCs mediated stabilization of Foxp3 expression in already differentiated Tregs and their ability to cause an efficient de novo conversion of Foxp3+ Tregs from stimulated Foxp3−CD4+ T cells. These effects occurred independent of TGF-β signaling. Therefore, the therapeutic potential of MDSCs could be harnessed as a multipronged strategy to confer an infectious tolerance to the host by activating endogenous regulatory mechanisms.
Prevalance of Correlation Between Temporomandibular Dysfunction and Occupational Stress in White Collar Professionals
Authors: Gawade Krutika D. , Vardharajulu G. 
Published: July 2019

Aims:
Occupational stress (OS) is regarded as associated factor for causing temporomandibular joint temporomandibular dysfunction (TMD). However, there is little knowledge on the relationship between incremental OS and its role in causing TMD. The purpose of the study is to determine the relationship between OS and TMD. This study will help to provide the basic data to improve the conditions at the worksite and enhance the quality of life.

Materials and Methods:
A cross-sectional study was conducted among 100 white-collar professionals (WCPs) in Karad. To determine the prevalence of TMD, the scaled named Anamnestic Index by Fonseca was used. OS was assessed by the OS Index Scale. Data obtained from the outcome measures were analyzed using InStat, adopting a 5% significance level. Brief analysis was made, and the Pearson correlation test was used to find the correlation between TMD and OS.

Results:
The results obtained by OSI stated that majority of WCP experienced moderate stress (67%) highest among teachers. Fifty-three percent prevalence of TMD was noted, highest among teachers. The major correlation noted in moderate OS group (38%) majorly affecting teachers. The gender-wise findings noted females (53%) were more prone. Age-wise findings stated more prevalence among 31–40 years (56%).

Conclusion:
The results of this study show that a significant percentage of population had signs of TMDs, and there are high chances they may develop symptoms in the future. It is necessary to prevent the OS in WCP by improving working conditions, emotional stability, and frequent postural changes. Further studies are necessary for documentation of these preventive measures.
Las técnicas gráficas en los proyectos de la Universidad de Granada. Un recorrido de la ilustración a la autarquía
Authors: Vílchez Lara María del Carmen 
Published: July 2019

<p>El análisis de la documentación gráfica presentada por los arquitectos que estuvieron al frente de las obras de nueva planta o rehabilitación del patrimonio arquitectónico de la universidad granadina es inseparable, entreotros, de la formación académica que aquéllos recibieron, además de los avances técnico-científicos acontecidos en el campo de la arquitectura en el periodo de tiempo estudiado. Iniciando el recorrido con los sencillos planos trazados a plumilla por los padres o hermanos jesuitas que proyectaron el Colegio de San Pablo, convertido en sede universitaria en 1767, atravesaremos los artísticos dibujos del periodo ilustrado hasta llegar a las insípidas copias monocromáticas de los años siguientes a la Guerra Civil y detectar los dos puntos de inflexión que afectaron de manera decisiva y con desigual resultado a las técnicas gráficas utilizadas en estos proyectos: la Instrucción liberal de 1860 y la aparición de las copiadoras heliográficas en los albores del siglo xx.</p>
Los artesonados renacentistas del Palacio Ducal de Pastrana (Guadalajara): análisis geométrico
Authors: González Uriel Ana , De Miguel Sánchez Manuel , Fernández-Cabo Miguel C. 
Published: July 2019

<p>Pastrana conserva uno de los conjuntos más relevantes de artesonados renacentistas en España, trazados por Alonso de Covarrubias y ejecutados por Cristóbal de Nieva y Justo de Vega en 1549-50. Con la llegada del Renacimiento, los techos de madera habían adoptado formas al romano y tramas geométricas con teselaciones de polígonos presentes en restos de la antigüedad. Mientras en el resto de Europa estos patrones poblaban techos planos, el oficio y conocimiento geométrico de los carpinteros peninsulares, herederos de la tradición visigoda e hispanomusulmana, permitió su ejecución sobre techos poliédricos, en un desarrollo que supera la mera copia de formas importadas de Italia. El artículo analiza los diferentes trazados presentes en Pastrana y las variadas estrategias para encajar las teselaciones planas en la configuración de los paños inclinados, especialmente en el diseño de los cuartos de limas.</p>

Published: July 2019

<p>Durante los años ochenta del siglo pasado, se dieron las condiciones para reivindicar un pensamiento crítico capaz de extender el discurso de la arquitectura a la sociedad. Desde algunas escuelas de arquitectura que apostaron por una arquitectura más diversa y culturalmente accesible al gran público, se procuró el acceso a su producción gráfica mediante iniciativas de difusión que incluían publicaciones, exposiciones y otros eventos. A través de un dibujo más lúdico que había incorporado elementos de la publicidad o la cultura pop, una nueva generación de arquitectos, pretendían expresar su desacuerdo con el corsé estético impuesto por los postulados de la modernidad. En su diversidad, estas propuestas gráficas poseen una serie de elementos comunes: la transgresión de los sistemas de representación convencionales, la inclusión de elementos dinámicos mediante la incorporación de escenas al más puro estilo cinematográfico, y el deseo de introducir narraciones paralelas al discurso arquitectónico.</p>
De lo infraordinario a lo extraordinario. Trazos para una conceptualización arquitectónica
Authors: Vallespín Toro Nuria , Solana Suárez Enrique , Vega de ka Rosa Carmelo 
Published: July 2019

<p>Este artículo nace a partir de una observación asombrada de lo usual, de lo habitual, de lo ordinario, y aún más profundo: de lo infra-ordinario. En arquitectura, la apropiación e instrumentalización de lo cotidiano se ha convertido en los últimos años en una práctica recurrente. Nos proponemos examinar el tránsito de lo infraordinario hacia lo extraordinario mediante una peculiar manera de representar a través del dibujo. Trataremos de poner de relieve ciertos modos de representación de proyectos que en la última década se han caracterizado por una toma de conciencia de la escasez de recursos económicos y medioambientales, haciendo visibles acciones cotidianas en el medio urbano, arquitectónico y artístico. Lo infraordinario permite revelar el potencial subversivo de lo cotidiano, para llegar a convertirse en ocasiones en experiencias extraordinarias. En definitiva, lo infraordinario es lo extraordinario, y es en lo cotidiano donde radica el germen de lo extraordinario. </p>

Sen’s Capabilities Approach and the Measurement of Communication Outcomes
Authors: Jacobson Tom , Chang Leanne 
Published: July 2019

AbstractAmartya Sen’s capabilities approach to development defines development as an increase in freedoms citizens have to choose preferred development options. While Sen’s more recent writings are theoretical and philosophical his work was originally based in social choice theory, which comprises a tradition in quantifying and analyzing collective preferences, or choices among preferences. This article argues that such aggregation procedures can be useful in research devoted to communication for development (C4D). They can be employed in evaluating the outcomes of processes intended to facilitate participation in decision making, in both small and large-scale project settings.
L’histoire de l’Association des archivistes du Québec (AAQ)
Authors: Fortin-Dupuis Simon 
Published: July 2019

L’Association des archivistes du Québec (AAQ), en tant que regroupement de professionnels, a fortement marqué la discipline archivistique au cours de ses 50 années d’existence. Cette influence a déjà été étudiée à l’aune de la perspective disciplinaire. En s’appuyant plutôt sur l’évolution de l’organisation interne de l’Association, on découvre des dynamiques sous-jacentes à l’évolution de la perception des professions de l’archivistique qui expliquent aussi des changements disciplinaires. Une attention particulière portée aux aléas financiers et aux changements à la distribution du pouvoir au sein de l’organisation montre les facteurs qui président à la hiérarchisation progressive du champ archivistique. Cette dynamique découle à la fois d’une quête d’efficience des membres et de l’administration de l’AAQ et d’un impératif de rentabilité imposé par le contexte social québécois. Au travers des aléas de ces 50 ans d’activité, on découvre une Association qui a toujours su s’adapter au changement, malgré les grands défis qu’il représente, et maintenir l’objectif défini à sa naissance : promouvoir et défendre les intérêts des archives, des archivistes et de l’archivistique. Ce nouvel éclairage jeté sur l’histoire de l’AAQ permet finalement de rappeler certaines conditions du maintien de la cohésion de l’Association des archivistes du Québec.

Published: July 2019

Prevalensi HIV pada kelompok Penasun selalu menduduki peringkat tertinggi dibanding kelompok populasi kunci lainnya. Studi cross sectional dilakukan untuk mengetahui faktor risiko yang berhubungan dengan infeksi HIV pada populasi Penasun DKI Jakarta. Penelitian ini menggunakan data sekunder dari pelaksanaan Sero Survei HIV/Sifilis yang terintegrasi dengan Survei Cepat Perilaku di DKI Jakarta pada tahun 2013 - 2014. Populasi penelitian ini adalah Penasun di DKI Jakarta, sampel 240, pemilihan sampel menggunakan metode RDS (Responden Driven Sampling). Model akhir analisis multivariate cox regression menunjukkan bahwa variabel yang paling berkontribusi terhadap infeksi HIV di kalangan Penasun adalah sikap sharing jarum suntik PR 2,42 (95% CI = 1,33 – 4,41) dan lama menjadi Penasun PR 1,78 (95% CI = 1,23 – 2,57). Sikap sharing jarum suntik walaupun hanya dilakukan sekali berdampak kuat meningkatkan risiko infeksi HIV dan variabel lama menjadi Penasun berpengaruh terhadap melemahnya sikap konsisten untuk tidak sharing jarum suntik.

Authors: Awoyesuku P. A. , Altraide B. O. A. 
Published: July 2019

Background: Effective contraception can prevent unwanted pregnancy, unsafe abortion and ensure adequate birth spacing. The choice of a method depends on consideration of its advantages and disadvantages based on individual perception and interpretations.
Objective: To assess contraceptive choices and acceptability among new clients at the family planning clinic of a tertiary health facility in Rivers State, Nigeria.
Methodology: This was a one-year retrospective review of clinical records of new clients attending the Family Planning Unit of the Rivers State University Teaching Hospital from January 1, to December 31, 2018. Data on age, education, marital status, parity, contraceptive choice and reason for contraception were retrieved and analyzed using Epi-Info version 7.1.4.
Results: A total of 124 female clients were enrolled during the time period. The mean age of the participants was 33.8±5.1 years and the median parity was 3. The most common method of contraception accepted by the clients was implants 87 (70.2%), followed by intrauterine device 32 (25.8%), then injectable 4 (3.2%) and oral contraceptive pills 1(0.8%). Reasons proffered for use of contraceptive was mainly completed family size 69 (55.6%), pregnancy prevention 53 (42.8%) and child spacing 2 (1.6%). There was no significant difference on comparism of mean age and median parity of clients by choice of contraceptive method.
Conclusion: The implant methods were the most commonly accepted, while the oral contraceptive pill was the least preferred. Completed family size was the most common reason for contraception.
Exploration for Marble Deposit in Parts of Okpella, South-Southern Nigeria
Authors: Ozegin K. O. 
Published: July 2019

The ultimate aim of the electrical resistivity survey is to determine the resistivity distribution with depth on the basis of surface measurements of the apparent resistivity and to interpret it in terms of geology. Marble deposit was investigated with the application of electrical resistivity method using Vertical Electrical Sounding (VES) technique with the aim of characterising this deposit in parts of Okpella. Six (6) VES were acquired using the Schlumberger array for data acquisition with current electrode spacing varying from 1.0 to 150.0 m. The VES data obtained were interpreted using ipi2win Software. The results showed three layers indicating subsurface geologic sequence probed 26.4 m and beyond with clay/clayey sand (23.3 – 219.1 Ωm), sand (423 - 2040 Ωm) and marble (12661 - 404498 Ωm). The occurrence of marble deposit was revealed at VES points at 1, 2 and 5 in the studied area. This study concluded that the study area had occurrence of the marble deposits, which would be of economic importance, if exploited.
