La perfección de Eça de Queiroz
Authors: Ayala Kristhian 
Published: August 2019

En la sección Otra voz, se publica la traducción del relato mitológico “La perfección” de Eça de Queiroz. Este célebre escritor portugués es uno de los más notables novelistas de fines del XIX; aunque destacó en el naturalismo imperante de la época, en sus relatos cortos aprovechó las vetas y oportunidades que le ofrecía la ficción fantástica y mitológica. En este caso, "La perfección" es un relato que recrea el viaje azaroso de Ulises a Ítaca y su encuentro con la divina Calipso.
Literatura y cine
Authors: Bastazin Vera 
Published: August 2019

La literatura, como fenómeno de lenguaje, dialoga con otros códigos de calidad artística que, así como ella, también se expresan por medio de un discurso abierto a la perspectiva plurisignificativa e incluso multicultural. En este trabajo, la autora muestra cómo la literatura suscita la constitución de la imagen poética y está en consonancia con el cine en el acto de reflexionar sobre su propia potencialidad como narrativa de ficción.

Published: August 2019

Introducción: la frecuencia del trauma cardiaco se ha incrementado en los últimos años, se desconoce el mecanismo de remodelación miocárdica en estos pacientes.
Objetivos: evaluar la remodelación cardiaca en pacientes con herida penetrante de corazón comparando dos grupos, con y sin infarto de miocardio traumático asociado. Metodología: estudio observacional, tipo cohorte y prospectivo. La cohorte expuesta fueron pacientes mayores de 12 años con herida de corazón e infarto traumático y los no expuestos no tuvieron infarto. En el periodo posoperatorio y seis meses después se realizó una evaluación clínica, ecocardiográfica y funcional.
Resultados: se incluyeron 31 pacientes de sexo masculino y dos de sexo femenino, con edad promedio de 31 años. Más de 90% de las heridas fueron por arma cortopunzante. La fracción de eyección y la fracción de acortamiento al inicio fueron significativamente menores en los pacientes con infarto traumático. La única variable con diferencia significativa entre los dos grupos fue la fracción de acortamiento (30.18 Vs. 34.72, p < 0.05). Seis meses después ambos grupos mejoraron la capacidad funcional, el grosor relativo de la pared disminuyó. Los pacientes con infarto tuvieron más probabilidad de desarrollar hipertrofia excéntrica (RR: 2.67 IC = 0.72-9.89). Las demás variables ecocardiográficas fueron similares al inicio y a los seis meses en ambos grupos.
Conclusión: los pacientes con infarto traumático desarrollaron hipertrofia excéntrica. A pesar de la demostración de un patrón claro de remodelación ventricular, las diferencias son pequeñas debido al número de pacientes y al corto tiempo de seguimiento
The Tayler Instability in the Anelastic Approximation
Authors: Goldstein J. , Townsend R. H. D. , Zweibel E. G. 
Published: August 2019

Abstract
The Tayler instability (TI) is a non-axisymmetric linear instability of an axisymmetric toroidal magnetic field in magnetohydrostatic equilibrium (MHSE). In a differentially rotating radiative region of a star, the TI could drive the Tayler–Spruit dynamo, which generates magnetic fields that can significantly impact stellar structure and evolution. Heuristic prescriptions disagree on the efficacy of the dynamo, and numerical simulations have yet to definitively agree upon its existence. The criteria for the TI to develop were derived using fully compressible magnetohydrodynamics, while numerical simulations of dynamical processes in stars frequently use an anelastic approximation. This motivates us to derive new anelastic Tayler instability criteria. We find that some MHSE configurations are unstable in the fully compressible case but become stable in the anelastic case. We find and characterize the unstable modes of a simple family of cylindrical MHSE configurations using numerical calculations, and we discuss the implications for fully nonlinear anelastic simulations.

Abstract
We use Atacama Large Millimeter Array observations of the host galaxy of the quasar ULAS J1342+0928 at z = 7.54, to study the dust continuum and far-infrared lines emitted from its interstellar medium (ISM). The Rayleigh–Jeans tail of the dust continuum is well sampled with eight different spectral setups, and from a modified blackbody fit we obtain an emissivity coefficient of β = 1.85 ± 0.3. Assuming a standard dust temperature of 47 K we derive a dust mass of M
dust = 0.35 × 108
M
☉ and a star formation rate of

. We have >4σ detections of the

,

, and

atomic fine structure lines and limits on the

, and

emission. We also report multiple limits of CO rotational lines with J
up ≥ 7, as well as a tentative 3.3σ detection of the stack of four CO lines (J
up = 11, 10, 8, and 7). We find line deficits that are in agreement with local ultra-luminous infrared galaxies. Comparison of the

and

lines indicates that the

emission arises predominantly from the neutral medium, and we estimate that the photodisassociation regions in J1342+0928 have densities ≲5 × 104 cm−3. The data suggest that ∼16% of hydrogen is in ionized form and that the H ii regions have high electron densities of n

e
> 180 cm−3. Our observations favor a low gas-to-dust ratio of <100, and a metallicity of the ISM comparable to the solar value. All the measurements presented here suggest that the host galaxy of J1342+0928 is highly enriched in metal and dust, despite being observed just 680 Myr after the big bang.

Abstract
We have been conducting the Giant Metrewave Radio Telescope High Resolution Southern Sky (GHRSS) survey for the last four years and have discovered 18 pulsars to date. The GHRSS survey is an off-Galactic-plane survey at 322 MHz in a region of the sky (decl. range −40° to −54°) complementary to other ongoing low-frequency surveys. In this paper we report the discovery of three pulsars (PSRs), J1239−48, J1516−43, and J1726−52. We also present timing solutions for three pulsars previously discovered with the GHRSS survey: PSR J2144−5237, a millisecond pulsar with a period P = 5 ms in a 10 days orbit around a ≤0.18 M⊙ companion; PSR J1516−43, a mildly recycled P = 36 ms pulsar in a 228 days orbit with a companion of mass ∼0.4 M
⊙; and the P = 320 ms PSR J0514−4408, which we show is a source of pulsed γ-ray emission. We also report radio polarimetric observations of three of the GHRSS discoveries, PSRs J0418−4154, J0514−4408, and J2144−5237.

Following identification of an image artefact on a newly commissioned mammography system, the grid was initially not suspected as the cause as grid artefacts are generally associated with lines. A reference phantom image was taken at an accredited centre was used to resolve the problem. It is therefore felt to be essential for instructions not subject to peer evaluation to use phantoms.
Tropical Forest: A Potential Resource for Climate Change Mitigation in Ghana
Authors: Amankwah Emmanuel 
Published: August 2019

Climate variability and change has become a global phenomenon with many countries including Ghana working hard to mitigate the effect or develop strategies for adaptation. However, tropical forest has been identified to have the capacity to mitigate the impact of climate change and improve the general environment. The forest plays a critical role in the climate system, hydrology and the carbon cycle, and provide livelihood for over 2.5 billion rural dwellers in developing countries. This article therefore highlights the importance of tropical forest as a potential resource for climate change mitigation and the need for policy makers, stakeholders and the general public to seriously adopt positive approach to the management of forest resources. The article was carried out through extensive review of literature, official reports and policy documents. The paper outlines the threat of climate change, the state of Ghana’s forest and climate, and the role of the forest to mitigate climate change. It also highlights the socio-economic benefits of the forest in mitigating the changing climate. The documents reviewed showed that the state of Ghana’s forest has dwindled over the years through anthropogenic activities and the climate is also changing. It was also established that trees can remove substantial amount of CO2 from the atmosphere for storage. The paper concludes with recommendations for the preservation and regeneration of the tropical forest for the purpose of mitigating the effect of climate change in Ghana.
Nitrogen Fertilization and Inoculation of Seeds with Rhizobium tropici on the Agronomic Performance of Common Beans
Authors: Capelesso Darlan , Costa Antonio Carlos Torres da , Júnior José Barbosa Duarte 
Published: August 2019

Aims: This study aimed to evaluate the influence of nitrogen fertilization and inoculation of seeds with Rhizobium tropici on the agronomic performance of common bean (Phaseolus vulgaris L.).
Study Design: The experimental design consisted of a randomized block in a 4x2 factorial layout, with 4 replicates, the first factor referring to inoculant doses (0, 50, 100 and 200 mL for each 25 kg of seed), while the second refers to nitrogen fertilization (0 and 40 kg ha of N).
Place and Duration of Study: The study was conducted to the field in a no-till system area, in the southwestern region of Paraná, Brazil. The soil is classified as a Purple Latosol, with a clayey texture.
Methodology: The adopted spacing was 0.45 m between rows, and the seeding density used was 12 seeds per furrow meter. The inoculants NITRO 1000 Rhizobium tropici SEMIA 4077 and SEMIA 4088 were applied, varied according to the treatments. The cultivar used was IPR – Tangará.
Results: As for grain yield, it was observed that nitrogen fertilization did not contribute to the increase in grain yield, and higher productivity was obtained in the absence of N. This was probably due to the high content of organic matter present in the soil.
Conclusion: Nitrogen fertilization at sowing and seed inoculation with Rhizobium tropici did not influence the plant population and the 1000-grain mass. In the absence of nitrogen fertilization at sowing, pods with a longer length and higher grain yield were obtained. Inoculation of the seeds with Rhizobium tropici exerts a positive influence on plant height, number of nodes of the main stem, number of pods per plant, and number of beans per pod, the dose recommended by the manufacturer (100 mL) being efficient, with the possibility of applying a dose of 50 mL, to satisfactory results.

Published: August 2019

This paper presents the evaluation of propagation losses due to rain attenuated signal on terrestrial radio link. Rain rate data were measured using Davis weather station for the months of July, August and October 2017 at (9.9565° N, 8.8583° E; 1258 meters) Jos Plateau state of Nigeria. The data were analyzed using Microsoft Excel application package. Results were calculated based ITU-Recommendation. The result for the month of July shows that rain attenuated signals become more severe from rain rate of 90 mm/hr at 0.014% to 160 mm/hr at 0.002% with attenuation of 31.215dB and 105.951dB respectively. Also, the month of August shows that rain attenuated signals become more severe from rain rate of 70mm/hr at 0.017% to 200mm/hr at 0.002% with attenuation of 69.509dB and 108.324dB respectively. Furthermore, the month of October shows that rain attenuated signals become more severe from rain rate of 70mm/hr at 0.014% to 160 mm/hr at 0.004 with attenuation of 50.301dB and 135.336dB respectively. Therefore, results from this study revealed that rain attenuated signals on terrestrial radio links in Jos-Nigeria is more severe at higher rainfall rate (above 60 mm/hr) and lower exceeded frequency percentage of time (0.01% to 0.001%).

Abstract
This study describes antibiotic use by small-scale freshwater aquaculture farmers in the upper Mekong Delta in southwestern Vietnam and the knowledge and practices surrounding the cause and prevention of aquaculture disease in that region. Forty five farmers were included in the study, of which 19 (42%) cultivated tilapia Oreochromis spp., 13 (29%) Striped Catfish Pangasianodon hypophthalmus and 13 (29%) giant river prawns Macrobrachium rosenbergii. Antibiotics were used by farmers of tilapia and Striped Catfish (84% and 69% of farmers, respectively), but not by any of the prawn farmers. Most farmers (72%) used antibiotics for around 3 d when treating diseases, depending on the farmers' economic means and whether the fish recovered, as judged by the farmer. If farmers perceived that the antibiotic treatment had failed, the most common response was to change to another type of antibiotic. Some farmers also used antibiotics in the absence of clinical symptoms as a preventive measure. In the absence of rapid, cost-effective diagnostics, the likelihood for the incorrect use of antibiotics is high, which has implications for antibiotic resistance. Moreover, the sequential use of different antibiotics following therapeutic failure is a risk factor for the emergence of resistance. All farmers that were surveyed were aware of the risks associated with antibiotic use. This may lead to successful intervention toward reduced antibiotic use in freshwater fish farming in Vietnam.

AbstractPolymorphs of organic semiconductors are of great interest as they shed light to structure‐property relationships. The full X‐ray thin film structure analysis of two polymorphs (B, G) of an important n‐type semiconducting dicyano‐distyrylbenzene based small molecule (CN‐TFPA) is reported. Drastically different structures of the monotropic phases are revealed, that is an uncommon 2D crossed π‐stacked arrangement for the B‐phase versus a 1D slipped π‐stack for G. Both phases exhibit a layered structure in the (100) plane with high structural integrity, driven by the hydrophobic contacts of the terminal CF3 groups; as (100) coincides with the film surface, this allows for exfoliation by scotch tape. An in‐depth time‐dependent density functional theory (TD‐DFT) based quantum mechanics/molecular mechanics (QM/MM) study reveals all subsequent significantly differing optical and electronic responses which result from the different arrangements: the B film shows little excitonic interaction with strong blue fluorescence, amplified spontaneous emission (ASE), and good 2D n‐type transport. The G film forms H‐aggregates with strong green fluorescence, no ASE, and 1D n‐type charge transport. The established structure‐property relationships are seen as a crucial step for computer‐aided device analysis.

Published: August 2019

AbstractA nickel(II)/diamine‐catalyzed diastereo‐ and enantioselective Michael/hemiacetalization cascade reaction of α‐ketoesters with 2‐(2‐nitrovinyl)phenols has been established, thus providing a range of structurally diverse polysubstituted chromanes in good yields and excellent stereoselectivities (up to 89% yield, >20:1 dr, >99% ee). Moreover, the gram‐scale experiment was performed with only 0.5 mol% of catalyst, and tricyclic furanobenzodihydropyran compound was gained by the derivatization of product, which showed the great synthetic potential of this strategy.magnified image
Adverse effects of antipsychotic medication in patients with 22q11.2 deletion syndrome: A systematic review
Authors: de Boer Janna , Boot Erik , van Gils Lissa , van Amelsvoort Therese , Zinkstok Janneke 
Published: August 2019

AbstractThe 22q11.2 deletion syndrome (22q11.2DS) is a multisystem condition and the most prevalent microdeletion syndrome in humans. Approximately 25% of individuals with 22q11.2DS receive antipsychotic treatment. To assess whether patients with 22q11.2DS are vulnerable to adverse effects of antipsychotic medication, we carried out a literature review. A systematic search strategy was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Publications describing adverse effects of antipsychotic medication in patients with 22q11.2DS were included in the review and assessed for their methodological quality. A total of 11 publications reporting on eight trials, cross‐sectional or cohort studies, and 30 case reports were included. The most commonly reported adverse effects can be classified into the following categories: movement disorders, weight gain, seizures, cardiac side effects, and cytopenias. Many of these symptoms are manifestations of 22q11.2DS, also in the absence of antipsychotic medication. Based on the reviewed literature, a causal relation between antipsychotic medication and the reported adverse effects could not be established in the majority of cases. Randomized clinical trials are needed to make firm conclusions regarding risk of adverse effects of antipsychotics in patients with 22q11.2DS.

Published: August 2019

AbstractCoacervate microdroplets produced by liquid–liquid phase separation have been used as synthetic protocells that mimic the dynamical organization of membrane‐free organelles in living systems. Achieving spatiotemporal control over droplet condensation and disassembly remains challenging. Herein, we describe the formation and photoswitchable behavior of light‐responsive coacervate droplets prepared from mixtures of double‐stranded DNA and an azobenzene cation. The droplets disassemble and reassemble under UV and blue light, respectively, due to azobenzene trans/cis photoisomerisation. Sequestration and release of captured oligonucleotides follow the dynamics of phase separation such that light‐activated transfer, mixing, hybridization, and trafficking of the oligonucleotides can be controlled in binary populations of the droplets. Our results open perspectives for the spatiotemporal control of DNA coacervates and provide a step towards the dynamic regulation of synthetic protocells.
