Published: August 2019

El ruido ambiental, es una de las principales formas de contaminación en las ciudades y que afecta la calidad de vida de las personas. En este artículo, se presenta una metodología que utiliza un enfoque basado en la Información Geográfica Voluntaria (VGI, por sus siglas en inglés) para el monitoreo, análisis y predicción del ruido ambiental, lo cual puede resultar muy útil para plantear alternativas que mejoren la vida en una ciudad. El presente trabajo considera las fases de adquisición de los datos, análisis y procesamiento de los datos, así como la visualización de la información, considerando la temporalidad de los mismos y tomando en cuenta niveles de análisis a nivel macro y micro para la superficie de estudio. Se presentan algunos detalles del diseño y desarrollo de un sistema de información geográfica, compuesto por una aplicación web de mapas, una aplicación para dispositivos móviles denominada “NoiseMonitor”, el análisis geoespacial y los métodos de aprendizaje automático (máquinas de soporte vectorial y redes neuronales artificiales) para la predicción de ruido ambiental; utilizando información contextual; es decir, algunos datos relacionados con la ciudad. Se busca aprovechar la disposición de los ciudadanos de participar colaborativamente para monitorear su entorno y ser considerados como sensores humanos, lo cual a diferencia con los enfoques tradicionales, el costo asociado al desarrollo e implementación de este proyecto es mucho menor.

La poesía migrante andina en el Perú del siglo XX
Authors: Medina Cabrera Shéridan 
Published: August 2019

Esta investigación pretende evidenciar la presencia de una tradición poética migrante andina a lo largo del siglo XX a partir de las poéticas más resaltantes que desarrollen la retórica migrante durante este periodo. La literatura migrante, para el caso concreto, la poesía migrante andina, estaría inscrita y sería una literatura heterogénea que conformaría parte de otra de mayor heterogeneidad que es la literatura peruana en sí, entendiendo a esta última como la que alberga literaturas internas varias, todas de carácter nacional y autónomo, y que harían de su conjunto una “totalidad contradictoria”. En el presente artículo, se propone hacer un recuento de las principales poéticas migrantes que se sucedieron en el transcurso del siglo pasado evidenciando, con su linealidad y regularidad, la existencia de una literatura migrante como poética representativa de la literatura peruana del siglo XX.
Representación, estereotipo y cuerpo afrodescediente en Roque Moreno, de Teresa González de Fanning
Authors: Leonardo Loayza Richard 
Published: August 2019

Este artículo pretende analizar la novela Roque Moreno (1899, 1904) de Teresa González de Fanning. El objetivo es mostrar que la autora de esta obra representa “lo negro” como algo que, a pesar de ser sometido a una serie de tecnologías sociales, tales como la mezcla de razas, la educación o la religión, no es capaz de superar su estado original, que se define en términos de salvajismo y barbarie. Este estado, según lo propuesto por González de Fanning, se deposita en el cuerpo de los afrodescendientes, que sirve como un resto que se repite constantemente, por lo que condena a este sujeto étnico-racial a la repetición de comportamientos ancestrales que están más allá de su dominio. Para realizar dicho análisis se empleará la Teoría literaria, los Estudios de Género, los Estudios Subalternos y los Estudios Poscoloniales.
Drummond, entre la culpa social y la culpa familiar
Authors: Camilo Vagner 
Published: August 2019

El presente ensayo retoma un aspecto de un libro dedicado al giro clasicista de Nuevos Poemas (1948) y, sobre todo, Claro Enigma (1951), examinado a la luz de un contexto marcado, de un lado, por la especialización del trabajo intelectual y artístico de los años 40-50, responsable de ciertas tendencias formalistas y esteticistas en la lírica del período; de otro, por el recrudecimiento de la política zdanovista adoptada por el PCB (Partido Comunista Brasileño) en la posguerra, que —sumada a lo que ya fuera revelado por los expurgas stalinistas y los procesos de Moscú— acabó por redundar en la desilusión con la militancia y en el pesimismo dominante en esta fase de la obra de Drummond.

TOQUE DE AXÉ: UM OLHAR SOBRE AS ESPACIALIDADES UMBANDISTAS
Authors: Pereira Rogério Amaral 
Published: August 2019

As manifestações umbandistas assentadas na cidade de Rio Grande-RS são de uma riqueza ímpar. E direcionar o olhar para a devoção é transitar no mundo do sagrado e de suas linguagens espacializadas, as quais compõem as sacralidades urbanas. Refletir sobre a musicalidade religiosa leva à incidência da existencialidade humana, ou seja, de um encontro preso não só ao caráter institucional, mas ao pertencer do indivíduo praticante religioso como ser capaz na sua forma de relacionar-se com o mundo. Assim, o presente artigo objetiva a reflexão sobre a espacialidade cultural religiosa e a sua relação com a musicalidade dos praticantes religiosos. Com isto, o estudo é composto pela observação e investigação de três comunidades religiosas umbandistas rio-grandinas: o Centro Espiritualista “Reino de São Jorge”, o Centro Espiritualista “Tenda de São Jorge” e o Centro Espírita de Umbanda “Cristo Redentor”, realizadas entre os anos de 2013 e 2015, as quais compuseram o cabedal de pesquisa de campo. Neste sentido, a pesquisa consiste ainda no diálogo geográfico, pautado na exposição das falas dos praticantes umbandistas entrevistados que permitiram pressupostos para análise das lembranças devocionais e suas espacialidades, na compreensão das manifestações sociais, onde são cultivadas as devoções.

Introducción: la enfermedad renal aguda (ERA) se presenta en el postrasplante de hígado con una incidencia que varía de 12-64%, con una mortalidad intrahospitalaria asociada de 40-67%. Este estudio utiliza los criterios RIFLE para analizar el efecto del esquema inmunosupresor con inhibidores de la calcineurina en la aparición de ERA en los primeros quince días postrasplante de hígado. También evalúa el protocolo de introducción tardía y progresiva de los medicamentos inhibidores de la calcineurina (CNi) como estrategia para disminuir la incidencia de ERA postrasplante.
Métodos: estudio analítico de cohortes de 163 pacientes con trasplante de hígado.
Resultados: ciento sesenta y tres pacientes cumplieron con los criterios de inclusión del estudio con un promedio de edad de 51 (46-56) años. De éstos, sólo 11 (6.74%) presentaron ERA postrasplante. Ciclosporina fue administrada a 126 (77.3%) de los pacientes trasplantados y tacrolimus a 21 (12.88%). Inmediatamente después del trasplante los pacientes fueron clasificados en dos grupos: pacientes con riesgo alto de desarrollar ERA y pacientes sin problemas renales. A los primeros se les inició el CNi a partir del tercer día postrasplante y a los últimos entre seis y 18 horas después del trasplante, a una dosis que se aumentó gradualmente
Conclusiones: la introducción tardía y progresiva de los CNi podría ser una estrategia efectiva para disminuir la incidencia de ERA en el postrasplante de hígado
Role of ultrasound in the imaging of parotid swellings
Authors: Wang W. T. , Ahuja A. T. , Metreweli C. 
Published: August 2019

This pictorial essay details anatomy of the normal parotid as well as a spectrum of intra- and extraparotid pathology. Extraparotid lesions which mimic aparotid swelling are well characterised on ultrasound. In addition, sonographic features of intraparotid neoplasms, inflammation and infection are also illustrated. We recommend ultrasound as a useful first line approach in the evaluation of parotid disease, and also as an aid to guide biopsy of both intra- and extraparotid masses.

AbstractHigh-grade gliomas, metastases, and primary central nervous system lymphoma (PCNSL) are common high-grade brain lesions, which may have overlapping features on magnetic resonance (MR) imaging. Our objective was to assess the utility of 18-fluoride-fluoro-ethyl-tyrosine positron emission tomography (FET-PET) in reliably differentiating between these lesions, by studying their metabolic characteristics. Patients with high-grade brain lesions suspicious for glioma, with overlapping features for metastases and PCNSL were referred for FET-PET by Neuroradiologists from Multidisciplinary Neuro-Oncology Joint Clinic. Tumor-to-contralateral white mater ratio (T/Wm) at 5 and 20 min was derived and compared to histopathology. Receiver operating characteristic curve analysis was used to find the optimal T/Wm cutoff to differentiate between the tumor types. T/Wm was higher for glial tumors compared to nonglial tumors (metastases, PCNSL, tuberculoma, and anaplastic meningioma). A cutoff of 1.9 was derived to reliably diagnose a tumor of glial origin with a sensitivity and specificity of 93.8% and 91%, respectively. FET-PET can be used to diagnose glial tumors presenting as high-grade brain lesions when MR findings show overlapping features for other common high-grade lesions.

Authors: Belarbi Z. , Dominguez Olivo J.M. , Farelas F. , Singer M. , Young D. , Nešić S. 
Published: August 2019

Carbon dioxide (CO2) corrosion mitigation is a challenge in the oil and gas industry. In order to decrease the severity of CO2 corrosion of carbon steel pipelines and equipment, different mitigation practices are recommended. One such strategy is the application of surface-active chemical inhibitors. The aim of this research was to evaluate the inhibition effectiveness of decanethiol in a CO2-saturated aqueous electrolyte (1 wt% NaCl). The inhibition properties of decanethiol were evaluated by electrochemical measurements (linear polarization resistance, potentiodynamic sweeps, and electrochemical impedance spectroscopy) and the steel surface was characterized by scanning electron microscopy. The obtained data show that decanethiol can successfully prevent corrosion of carbon steels in a CO2 environment. An inhibition mechanism was also proposed based on adsorption characteristics and inhibitor film formation.
On the radiation belt location during the 23rd and 24th solar cycles
Authors: Dmitriev Alexei V. 
Published: August 2019

Abstract. Within the last two solar cycles (from 2001 to 2018), the location of the
outer radiation belt (ORB) was determined using NOAA/Polar-orbiting
Operational Environmental Satellite (POES) observations of energetic electrons with
energies above 30 keV. It was found that the ORB was shifted a little
(∼1∘) in the European and North American sectors, while
in the Siberian sector the ORB was displaced equatorward by more than 3∘. The displacements corresponded qualitatively to the change in the geomagnetic field predicted by the IGRF-12 model. However, in the Siberian sector, the model has a tendency to underestimate the equatorward shift of the ORB. The shift became prominent after 2012, which might have been related to a
geomagnetic “jerk” that occurred in 2012–2013. The displacement of the ORB to lower latitudes in the Siberian sector can contribute to an increase in the occurrence rate of midlatitude auroras observed in the Eastern Hemisphere.
Antecedent accessibility and exceptional covariation: Evidence from Norwegian Donkey Pronouns
Authors: Kush Dave , Eik Ragnhild 
Published: August 2019

It is generally assumed that interpreting a co-referential or a syntactically-bound pronoun requires retrieving a representation of its antecedent from memory. Donkey pronouns (e.g., Geach 1962) are pronouns that co-vary in interpretation with non-c-commanding indefinite QPs in apparent violation of structural constraints on QP-pronoun relations (Reinhart 1976). Recent research (Moulton &amp; Han 2018) has hypothesized that the real-time processing of donkey pronouns may not involve retrieval of the co-varying indefinite QP as an antecedent, because non-c-commanding QPs are assumed to be inaccessible to retrieval. We tested this hypothesis with a self-paced reading study that compared the processing of standard co-referential pronouns and donkey pronouns in Norwegian. Contrary to the hypothesis, our results indicate that donkey pronouns retrieve a feature-matching antecedent from memory in a manner analogous to how co-referential pronouns retrieve a referential antecedent. Our findings imply that retrieval of a feature-matching antecedent is a necessary step in the processing of all pronouns, irrespective of their ultimate interpretation. Moreover, retrieval does not uniformly ignore non-referential NPs that fail to c-command a pronoun. We briefly discuss the implications of these findings for psycholinguistic models of anaphora resolution and formal theories of donkey pronouns.
Evaluation of the socially evaluated cold-pressor group test (SECPT-G) in the general population
Authors: Becker Linda , Schade Ursula , Rohleder Nicolas 
Published: August 2019

Background
In stress research, economic instruments for introducing acute stress responses are needed. In this study, we investigated whether the socially evaluated cold-pressor group test (SECPT-G) induces salivary alpha-amylase (sAA) and/or cortisol responses in the general population and whether this is associated with anthropometric, experimental, and lifestyle factors.

Methods
A sample of 91 participants from the general population was recruited. Salivary cortisol and sAA levels were assessed prior to (t0), immediately after (t1), and 10 min after the SECPT-G (t2).

Results
A robust cortisol increase was found immediately after the SECPT-G, which further increased between t1 and t2. This was independent of most of the control variables. However, men showed a trend toward higher cortisol increases than women (p = 0.005). No sAA responses were found at all. However, sAA levels were dependent on measurement time point with highest levels between 9 pm and 9:30 pm. Participants who immersed their hands into the ice water for the maximally allowed time of 3 min showed higher sAA levels at all time points than participants who removed their hands from the water earlier.

Conclusions
We conclude that the SECPT-G is a good means of an acute stress test when cortisol—but not necessarily sAA—responses are intended.
Bridged Azobenzenes and Their Biological Applications
Authors: Warner David J. , Keane Katie S. , Saint‐Louis Carl Jacky , Blackstock Silas C. 
Published: August 2019

Abstract
Capable of rapid and reversible conformational change in response to irradiation, azobenzene (AB) derivatives have been used in chemical systems to introduce on/off switchability and allow for photoregulation of the properties of such systems. Following a brief introduction of tuning AB absorption via substitution, this chapter summarizes the selected recent reports of applications of bridged ABs in biological systems or systems having potential biomedical utility. ABs have been used to achieve photocontrol of drug‐delivery systems, molecular actuators, deoxyribonucleic acid (DNA) nanomachines, enzyme activity, peptide structure and activity, and ion channels. This chapter describes how researchers have incorporated AB into biological systems as a photoresponsive switch to afford photocontrol of the chemical activity in such systems. The various works detailed in this chapter showcase the versatility of AB for use as a light‐responsive molecular switch in the photoregulation of biological processes. Additionally, light‐responsive AB‐derived macroscopic materials are also discussed, given their biomedical potential for use as artificial muscle.

AbstractObjectsThe diffusion‐based spherical mean technique (SMT) provides a novel model to relate multi‐b‐value diffusion magnetic resonance imaging (MRI) data to features of tissue microstructure. We propose the first clinical application of SMT to image the brain of patients with multiple sclerosis (MS) and investigate clinical feasibility and translation.MethodsEighteen MS patients and nine age‐ and sex‐matched healthy controls (HCs) underwent a 3.0 Tesla scan inclusive of clinical sequences and SMT images (isotropic resolution of 2 mm). Axial diffusivity (AD), apparent axonal volume fraction (Vax), and effective neural diffusivity (Dax) parametric maps were fitted. Differences in AD, Vax, and Dax between anatomically matched regions reflecting different tissues types were estimated using generalized linear mixed models for binary outcomes.ResultsDifferences were seen in all SMT‐derived parameters between chronic black holes (cBHs) and T2‐lesions (P ≤ 0.0016), in Vax and AD between T2‐lesions and normal appearing white matter (NAWM) (P < 0.0001), but not between the NAWM and normal WM in HCs. Inverse correlations were seen between Vax and AD in cBHs (r = −0.750, P = 0.02); in T2‐lesions Dax values were associated with Vax (r = 0.824, P < 0.0001) and AD (r = 0.570, P = 0.014).InterpretationsSMT‐derived metrics are sensitive to pathological changes and hold potential for clinical application in MS patients.
ROS‐Responsive Blended Nanoparticles: Cascade‐Amplifying Synergistic Effects of Sonochemotherapy with On‐demand Boosted Drug Release During SDT Process
Authors: Wu Pengying , Dong Wei , Guo Xuyan , Qiao Xiaoyang , Guo Shifang , Zhang Lei , Wan Mingxi , Zong Yujin 
Published: August 2019

AbstractSonodynamic therapy (SDT) not only has greater tissue‐penetrating depth compared to photo‐stimulated therapies, but also can also trigger rapid drug release to achieve synergistic sonochemotherapy. Here, reactive oxygen species (ROS)‐responsive IR780/PTL‐ nanoparticles (NPs) are designed by self‐assembly, which contain ROS‐cleavable thioketal linkers (TL) to promote paclitaxel (PTX) release during SDT. Under ultrasound (US) stimulation, IR780/PTL‐NPs produce high amounts of ROS, which not only induces apoptosis in human glioma (U87) cells but also boosts PTX released by decomposing the ROS‐sensitive TL. In the U87 tumor‐bearing mouse model, the IR780/PTL‐NPs releases the drug at the target sites in a controlled manner upon US irradiation, which significantly inhibits tumor growth and induces apoptosis in the tumor tissues with no obvious toxicity. Taken together, the IR780/PTL‐NPs are a novel platform for sonochemotherapy, and can control the spatio‐temporal release of chemotherapeutic drugs during SDT.
