Authors: Alam Nafisa , Maria Kazi Hanium , Rahman Mohammad Jellur , Sultana Parvin , Mieno Tetsu 
Published: September 2020

MWCNT/starch composites were prepared by simple solution casting method by incorporating upto 1.0 wt. % of multi-walled carbon nanotubes (MWCNTs) as reinforcing fillers in the starch matrix. Gelatin was used as dispersing agent to disperse the MWCNTs into aqueous solution and glycerol was used as plasticizer to form composites. SEM images of the MWCNT/starch composite show the homogenous surface of the composite where CNTs are embedded into the starch matrices. XRD spectra of the composite show no characteristic peaks of CNTs in the starch matrix. FTIR spectra show peaks at around 3435 and 2927 cm-1 indicating that the covalent bonds between –OH groups and C-H groups of soluble starch and CNT were formed in the composite. Electrical conductivity of the composite was enhanced from 2.85×10-9to 5.28× 10-8 S/m due to the addition of CNTs at room temperature and decreased with the increase of temperature. UV visible spectra showed increasing absorption with increasing CNTs content in the composite. TGA analysis demonstrated the stability of the MWCNT/starch composite.

Authors: Haider AFMY , Khan Zulfiqar Hasan 
Published: September 2020

Laser-induced breakdown spectroscopy (LIBS), which is a powerful technique for the detection of minor and trace elements in a sample, has been used to analyze the enriched zircon mineral collected from the beach sands of southern Bangladesh. In addition to zirconium, a large number of rare earth elements viz. cerium, lanthanum, praseodymium, neodymium, ytterbium, gadolinium, dysprosium, erbium, samarium, europium, holmium and yttrium and other associated elements like hafnium, niobium, tantalum, magnesium, calcium, sodium, titanium and iron along with non-metals like phosphorus and silicon were detected in the enriched zircon samples by the LIBS technique. To the best of our knowledge, this is the first time that multiple rare earth elements have been identified in natural zircon by LIBS.

Published: September 2020

O presente trabalho teve por objetivo avaliar a influência do glifosato na cultura da soja RR mediante uso de doses de glifosato em diferentes estádios fenológicos. Assim, montou-se
um experimento em delineamento em blocos casualizados, em esquema fatorial 4x4, com os tratamentos constituídos pela combinação de quatro doses de glifosato (0; 2; 4; 6 L/ha), aplicadas em quatro estádios fenológicos (V2, V4, V6 e V8), vegetativos da soja, com 4 repetições. A cultivar utilizada foi a DM 66I68 RSF IPRO. As variáveis analisadas foram altura da planta e de inserção da primeira vagem, diâmetro do caule, número de vagens por planta, número de grãos por vagem, massa de 1000 grãos e produtividade de grãos. Os dados para as doses de glifosato foram submetidos a análise de regressão e os dados para estádios fenológicos foram submetidos a teste Tukey ao nível de 5% de significância. Independente do estádio fenológico da cultura da soja, o uso de glifosato não interfere negativamente na altura de inserção da primeira vagem, diâmetro do colmo e massa de 1000 grãos. Recomenda-se a aplicação de glifosato até o estádio fenológico V4 da cultura da soja. Após este estádio, o herbicida interfere negativamente no número de grãos por vagem e a produtividade de grãos.

Welding techniques have been used extensively in the construction field because welding techniques are a simpler method in the process of connecting steel than using bolts or rivets. Factors that influence the quality of welding results include distance of the seam. The seam distance can affect the increase in heat input value because the wider the seam distance the more filler metal will be used. The purpose of this study was to determine how the effect of variations in the distance of the seam to the mechanical properties of SS400 steel welding material using the GMAW method. SS400 steel welding welding position 2G with variations in the root gap distance of 0 mm, 2 mm and 4 mm using the GMAW method with a type of protective gas 82% Ar + 18% CO2 and ESAB ER70S-6 type welding wire.

Background
Patients on dialysis with frequent comorbidities, advanced age, and frailty, who visit treatment facilities frequently, are perhaps more prone to SARS-CoV-2 infection and related death—the risk factors and dynamics of which are unknown. The aim of this study was to investigate the hospital outcomes in patients on dialysis infected with SARS-CoV-2.

Methods
Data on 224 patients on hemodialysis between February 29, 2020 and May 15, 2020 with confirmed SARS-CoV-2 were analyzed for outcomes and potential risk factors for death, using a competing risk-regression model assessed by subdistribution hazards ratio (SHR).

Results
Crude data analyses suggest an overall case-fatality ratio of 23% (95% CI, 17% to 28%) overall, but that varies across age groups from 11% (95% CI, 0.9% to 9.2%) in patients ≤50 years old and 32% (95% CI, 17% to 48%) in patients >80 years; with 60% of deaths occurring in the first 15 days and 80% within 21 days, indicating a rapid deterioration toward death after admission. Almost 90% of surviving patients were discharged within 28 days. Death was more likely than hospital discharge in patients who were more frail (WHO performance status, 3–4; SHR, 2.16 [95% CI, 1.25 to 3.74]; P=0.006), had ischemic heart disease (SHR, 2.28 [95% CI, 1.32 to 3.94]; P=0.003), cerebrovascular disease (SHR, 2.11 [95% CI, 1.20 to 3.72]; P=0.01), smoking history (SHR, 2.69 [95% CI, 1.33 to 5.45]; P=0.006), patients who were hospitalized (SHR, 10.26 [95% CI, 3.10 to 33.94]; P<0.001), and patients with high CRP (SHR, 1.35 [95% CI, 1.10 to 1.67]) and a high neutrophil:lymphocyte ratio (SHR, 1.03 [95% CI, 1.01 to 1.04], P<0.001). Our data did not support differences in the risk of death associated with sex, ethnicity, dialysis vintage, or other comorbidities. However, comparison with the entire dialysis population attending these hospitals, in which 13% were affected, revealed that patients who were non-White (62% versus 52% in all patients, P=0.001) and those with diabetes (54% versus 22%, P<0.001) were disproportionately affected.

Conclusions
This report discusses the outcomes of a large cohort of patients on dialysis. We found SARS-CoV-2 infection affected more patients with diabetes and those who were non-White, with a high case-fatality ratio, which increased significantly with age, frailty, smoking, increasing CRP, and neutrophil:lymphocyte ratio at presentation.
Movilización rural y liderazgos. Salta en las Guerras de Independencia
Authors: Mata Sara E. 
Published: September 2020

La insurrección que tuvo lugar en la provincia de Salta en el contexto de la guerra de independencia movilizó a amplios sectores de la población rural. Esta insurrección adquirió, sin embargo, diferencias sustanciales según se tratara del valle de Lerma, el valle Calchaquí o la Frontera. En esta oportunidad nos proponemos señalar algunas de estas diferencias, destacando la importancia que la movilización tuvo en el valle de Lerma, dónde los conflictos en torno a la tierra y al ganado a fines de la colonia brindaron las condiciones propicias para que la militarización expresara reivindicaciones sociales y políticas. Para ello es también preciso prestar atención a los liderazgos surgidos en el proceso insurreccional ya que los mismos permiten comprender los alcances y los límites del mismo.

Abstract
Recent surveys uncovered new young massive clusters (YMCs) that host dozens of red supergiants (RSGs) in the inner Milky Way. These clusters are ideal for studying the most recent and violent star formation events in the inner Galaxy. However, due to the high extinction that affects the Galactic plane, they need to be studied through infrared (IR) spectroscopy. IR spectra of RSGs have proven to be powerful tools for obtaining chemical abundances. We present the first [Fe/H] measurement (−0.07 ± 0.02) for the YMC VdBH 222 through analysis of its RSGs using Very Large Telescope/X-shooter spectra. We find no evidence for multiple stellar populations in this YMC, contrary to what is routinely observed in older massive clusters.
On Measuring Divergence for Magnetic Field Modeling
Authors: Gilchrist S. A. , Leka K. D. , Barnes G. , Wheatland M. S. , DeRosa M. L. 
Published: September 2020

Abstract
A physical magnetic field has a divergence of zero. Numerical error in constructing a model field and computing the divergence, however, introduces a finite divergence into these calculations. A popular metric for measuring divergence is the average fractional flux

. We show that

scales with the size of the computational mesh, and may be a poor measure of divergence because it becomes arbitrarily small for increasing mesh resolution, without the divergence actually decreasing. We define a modified version of this metric that does not scale with mesh size. We apply the new metric to the results of DeRosa et al., who measured

for a series of nonlinear force-free field models of the coronal magnetic field based on solar boundary data binned at different spatial resolutions. We compute a number of divergence metrics for the DeRosa et al. data and analyze the effect of spatial resolution on these metrics using a nonparametric method. We find that some of the trends reported by DeRosa et al. are due to the intrinsic scaling of

. We also find that different metrics give different results for the same data set and therefore there is value in measuring divergence via several metrics.
Du manuscrit de poème aux germes du roman : graines, pistes et restes
Authors: Vassevière Maryse 
Published: September 2020

Après avoir étudié par le passé plusieurs des dossiers génétiques des romans d’Aragon, je tenterai encore une fois la démonstration de l’utilité d’étudier ses manuscrits légués au CNRS en 1977 et maintenant conservés à la BnF par une nouvelle étude de cas : le poème « On dormait encore en ce temps-là » du recueil de la poésie de la Résistance La Diane française (1944) dont on décrira le matériau génétique avant d’en donner une transcription diplomatique. Le deuxième temps de l’étude consistera à analyser le mouvement perpétuel de la genèse en dégageant quelques règles de l’avancée de l’écriture. Pour finir par mettre en évidence dans les graines de cet avant-texte poétique quelques restes, rejetés, inaboutis, inexplorés, et qui vingt ans plus tard vont permettre le passage de la poésie au roman et alimenter l’écriture romanesque ultime du dernier Aragon. Centré sur un des rares manuscrits de travail de la poésie de la Résistance, cet article pourrait être une nuance apportée à l’image d’un Aragon Jupiter de sa propre genèse.
