Oil vanadylporphyrin complexes were obtained by extraction in the presence of N-N-dimethylformamide. In the chromatographic separation of vanadylporphyrin complexes, four main fractions were obtained from the oils of the oil field “North Buzachi” , where all types of known oil porphyrin structures were identified, dominated by deoxophylloerythroethioporphyrin – types with two absorption maxima of 534 Nm and 573 nm. It was found that the total concentration of vanadylporphyrin complexes registered in the absorption zone of 534 nm and 573 nm is 11 times higher than the concentration of nickelporphyrin complexes characteristic of the absorption zone of 550 nm. The ratio of vanadylporphirins of the etio - and deoxo-phylloerythroethioporphyrin (DPEP) type was 0.11. The results of the research allow us to conclude that the oil of the “North Buzachi” oil and gas district is a promising raw material for obtaining vanadylporphyrin complexes.

Development of the oil industry in Kazakhstan at the current stage is characterized by a decrease in the quality of the raw material base. In the total balance of fields under development, the fields that have entered the late stage of development prevail and, consequently, there is a significant deterioration in their structure, an increase in the share of hard-to-recover oil reserves, watering of beds and well production.One of the main challenges during the development of the field is the deposition of inorganic salts in the oilfield equipment. This article describes the main reasons for the formation of solid inorganic deposits in oil fields, methods of scale inhibitors, as well as the classification of scale inhibitors. Presents the physical and chemical characteristics of the objects under study: the properties of oils and watersof Uzen and Zhetybai oil fields and the chemical reagents – inhibitors of scale formations. Based on the results of laboratory studies, scale inhibitors were selected, which showed high efficiency (90 - 100 %) to prevent the precipitation of CaCO3, CaSO4 and BaSO4 under the conditions of Uzen and Zhetybai oil fields. The study was conducted in the center of scientific and laboratory research branch of KMG Engineering LLP "KazNIPImunaygas".

This article provides information about the method of obtaining potassium humate obtained from brown coal of the Lenger deposit, and also describes the elemental and mineralogical composition of potassium humate determined with SEM (JSM-6490l V, Jeol). Kinetic data on the decomposition of brown coal with solutions of potassium hydroxide are presented. The area of chemical reactions and the activation energy are determined. The benefits of the obtained potassium humate are that they are environmentally safe and have high bioactivity. They are also characterized by a high content of humic substances that are involved in the structure formation of the soil, accelerate biochemical processes, and increase the physical and chemical characteristics in the soil. Under the influence of humate-containing substances, the function of microflora elements in the soil is activated, and the number of beneficial microorganisms increases.

By the method of heat treatment, a mixture of graphite and salts was obtained from the foam graphite and the conditions for its effective production were determined. The composition of natural graphite of the GL-1 grade of the Russian deposit was determined. The study shows that the main element in graphite is a mixture of carbon and other elements. The analysis of energy dispersions showed the content of other elements in graphite. The content of Zn in the penografite obtained by elemental analysis was determined. In addition, the physicochemical properties of heat-treated graphite were investigated. Using IR spectroscopy, it was found that there are different groups on the surface of the penografite. Analysis of the CS-spectra of penografite allowed us to determine the structure of graphite and penografite. The conducted studies have shown that penografite differs depending on the forms of the spectrum, a set of spectral characteristics that allow us to quantify the degree of maturity of the crystal lattice and identify various defects. Raman spectroscopy for a full understanding of the results of the analysis, studies were carried out scanning electron microscopy (SEM) on a layered structure of penografia. The result of microanalysis and heat treatment shows that natural graphite has changed its composition and structure. It is established that the high-temperature thermal effect significantly changes the quantitative composition of the mixture and the content of various elements depends on the temperature of the thermal cover. The EDAX spectra of heat-treated graphite are shown.

The aim of this study was to evaluate the anti-helminthic effect of a commercial formulation Bioverm® (Duddingtonia flagrans) in 28 sheep naturally infected with gastrointestinal nematodes. Animals were classified into two groups: G1 (n=14) treated with nematophagous fungi and G2 (n=14) untreated control. The efficacy of the anti-helminthic drug was assessed based on the egg count per gram of feces (EPG) of strongyles, larval culture, hemogram, leukogram, plasma protein levels, mucosal coloration using the FAMACHA© method, animals body weight, and evaluating the ocular mucosa for the FAMACHA© anemia guide were performed at days 0, 30, 60, 90, 120, 150, and 180. Additionally, the nematode larvae were quantified in the dry matter of the pastures of both groups. Results showed that the EPG was significantly decreased in animals receiving nematophagous fungi from D30 until the experiment end. The most common nematode genus was Haemonchus (63%), followed by Cooperia (23%) and Trichostrongylus (15%). Based on the fecal egg count reduction test (FECRT), treated animals showed a reduction of fecal egg count of 58.9%, 8.6, 92.8%, 96.4%, and 96.2%, at D30, D60, D90, D120, and D180, respectively. The absolute values of red blood cells and leukocytes were significantly increased at D60 and D90, respectively, in the treated animals. A significant weight gain was observed in the treated ewes at the end of the experiment; however, there was no correlation between the EPGs values and hematocrit with the FAMACHA© degrees of animals in both experimental groups. The mean EPG of both groups and the number of infectious larvae in the pastures were not directly proportional. In conclusion, nematophagous fungi contributed to decreased parasitic load in sheep, and consequently, improve animal performance; they can be a suitable alternative to reduce problems associated with nematode infections.

Published: July 2021

Introduction

Alcohol intoxication affects aquaporins in the glial cells of brain resulting in oedema. Nux vomica, a homeopathic drug of plant origin, is known to counteract alcohol effect. The objective of this present study is to find out the level of free water molecules in the brain of a teleost fish under ethanol intoxication. The second objective is to determine whether Nux vomica could restore the level of free water in the alcohol treated fish.

Materials and methods

One group of fish was exposed to 456 mM ethanol for 30 min, another exposed first to a solution of Nux vomica 200c for 20 min and then to 456 mM ethanol for 30 min. The third group served as an untreated control. The mid brain of each fish was kept in an aluminium sample pan and its free water level was assessed by differential scanning calorimetry (DSC).

Results

All alcohol treated fish showed significant reduction in the level of free water molecules as compared to the untreated control. Treatment with Nux vomica increased the level of free water in the brain significantly as compared to the untreated alcoholic group.

Conclusion

Alcohol intoxication reduces free water molecules in the fish brain. Nux vom might have acted on aquaporins in the glial cells thereby increasing the level of free water in the brain.

Introduction: The aim of the present study was to describe different biological aspects of Ehrlich tumor in mice, such as body weight evolution, tumor growth rate, histological organization and systemic immune response after treatment with high-diluted thymulin (10-9 M, named 5CH). Methods: Tumor assessment was focused on macro- and microscopic aspects; parameters included occurrence of necrosis, embolism and tumor development, in addition to quantitative analysis of apoptosis (caspase-3), cell proliferation (Ki-67) and angiogenesis (vascular endothelial growth factor - VEGF) by means of specific immunohistochemistry markers. Spleen cell populations were evaluated by flow cytometry analysis. Results: Mice treated with thymulin 5CH exhibited changes in the tumor microenvironment, such as reduced micro-embolism incidence and cytokeratin expression, with increased caspase-3 expression in the tumor cells. These findings indicate some apoptotic activity by the tumor cells induced by the treatment, even though no reduction of the macroscopic tumor mass occurred. No changes in the systemic immune response were detected, as the balance among spleen cell populations remained unchanged. Conclusions: The results indicate that treatment of mice bearing Ehrlich tumor with thymulin 5CH induces some specific changes in the tumor environment. However, it did not influence systemic immunity parameters. Adjuvant use of thymulin 5CH in oncological clinical practice is still a matter of discussion.
Secondary Organic Aerosol Formation from Camphene Oxidation: Measurements and Modeling
Authors: Li Qi , Jiang Jia , Afreh Isaac , Barsanti Kelley C. , Cocker III David R.
Published: July 2021

Abstract. While camphene is one of the dominant monoterpenes measured in biogenic and biomass burning emission samples, oxidation of camphene has not been well-studied in environmental chambers and very little is known about its potential to form secondary organic aerosol (SOA). The lack of chamber-derived SOA data for camphene may lead to significant uncertainties in predictions of SOA from oxidation of monoterpenes using existing parameterizations when camphene is a significant contributor to total monoterpenes. Therefore, to advance the understanding of camphene oxidation and SOA formation, and to improve representation of camphene in air quality models, a series of experiments were performed in the University of California Riverside environmental chamber to explore camphene SOA yields and properties across a range of chemical conditions at atmospherically relevant OH concentrations. The experimental results were compared with modeling simulations obtained using two chemically detailed box models, Statewide Air Pollution Research Center (SAPRC) and Generator for Explicit Chemistry and Kinetics of Organics in the Atmosphere (GECKO-A). SOA parameterizations were derived from the chamber data using both the two-product and volatility basis set (VBS) approaches. Experiments performed with added nitrogen oxides (NOx) resulted in higher SOA yields (up to 64 %) than experiments performed without added NOx (up to 28 %). In addition, camphene SOA yields increased with SOA mass (Mo) at lower mass loadings, but a threshold was reached at higher mass loadings in which the SOA yields no longer increased with Mo. SAPRC modeling of the chamber studies suggested that the higher SOA yields at higher initial NOx levels were primarily due to higher production of peroxy radicals (RO2) and the generation of highly oxygenated organic molecules (HOMs) formed through unimolecular RO2 reactions. SAPRC predicted that in the presence of NOx, camphene RO2 reacts with NO and the resultant RO2 undergo hydrogen (H)-shift isomerization reactions; as has been documented previously, such reactions rapidly add oxygen and lead to products with very low volatility (i.e., HOMs). The end products formed in the presence of NOx have significantly lower volatilities, and higher O : C ratios, than those formed by initial camphene RO2 reacting with hydroperoxyl radicals (HO2) or other RO2. Moreover, particle densities were found to decrease from 1.47 to 1.30 g cm−3 as [HC]0/[NOx]0 increased and O : C decreased. The observed differences in SOA yields were largely explained by the gas-phase RO2 chemistry and the competition between RO2 + HO2, RO2 + NO, RO2 + RO2, and RO2 unimolecular reactions.

Abstract. The concept that geospace storms are comprised of synergistically coupled magnetic storms, ionospheric storms, atmospheric storms, and storms in the electric field originating in the magnetosphere, the ionosphere, and the atmosphere (i.e., electrical storms) was validated a few decades ago. Geospace storm studies require the employment of multiple-method approaches to the Sun–interplanetary medium–magnetosphere–ionosphere–atmosphere–Earth
system. This study provides general analysis of the 30 August–2 September 2019 geospace storm, the analysis of disturbances in the geomagnetic field and in the ionosphere, as well as the influence of the ionospheric storm on the characteristics of high frequency (HF) radio waves over the People's Republic of China. The main results of the study are as follows. The energy and power of the geospace storm have been estimated to be 1.5×1015 J and 1.5×1010 W, and thus, this storm is weak. The energy and power of the magnetic storm have been estimated to be 1.5×1015 J and 9×109 W, i.e., this storm is moderate, and a characteristic feature of this storm is the duration of the main phase of up to 2 d. The recovery phase also was lengthy and was no less than 2 d. On 31 August and 1 September 2019, the variations in the H and D components attained 60–70 nT, while the Z-component variations did not exceed 20 nT. On 31 August and 1 September 2019, the level of fluctuations in the geomagnetic field in the 100–1000 s period range
increased from 0.2–0.3 to 2–4 nT, while the energy of the oscillations
showed a maximum in the 300–400 to 700–900 s period range. During the
geospace storm, a moderately to strongly negative ionospheric storm manifested itself by the reduction in the ionospheric F-region electron
density by a factor of 1.4 to 2.4 times on 31 August and 1 September 2019, compared to the its values on the reference day. Appreciable
disturbances were also observed to occur in the ionospheric E region and
possibly in the Es layer. In the course of the ionospheric storm, the altitude of reflection of radio waves could sharply increase from ∼150 to ∼300–310 km. The atmospheric gravity waves generated within the geospace storm modulated the ionospheric electron density; for the ∼30 min period oscillation, the amplitude of the electron density disturbances could attain ∼40 %, while it did not exceed 6 % for the ∼15 min period. At the same time, the height of reflection of the radio waves varied quasi-periodically with a 20–30 km amplitude. The results obtained have made a contribution to the understanding of the geospace storm physics, to developing theoretical and empirical models of geospace storms, to the acquisition of detailed understanding of the adverse effects that geospace storms have on radio wave propagation, and to applying that knowledge to effective forecasting of these adverse influences.

Published: July 2021

Abstract. This study uses interferometric SAR techniques to identify landslides and lands prone to landslides, detect fringes and changes in areas struck by earthquakes. The pilot study investigates the Mila region (Algeria) which suffered significant landslides and structural damages (earthquake: Mw 5, 2020-08-07): the study checks ground deformations and tracks earthquake-induced landslides. DInSAR analysis shows normal interferograms, with atmospheric contribution, and slight fringes. However, it identifies many landslides, the most important (2.5 m displacement) being located in Kherba neighborhood, causing severe damages to dwellings. In addition, SAR images and optical images (Sentinel-2) confirm site investigations. Although in Grarem City, optical images could not detect any disorder, the DInSAR analysis detected some coherence decays and small fringes (3.94 km2 area). These unnoticed ground disorders were confirmed during fields inspection. Such results have key importance since they can serve as an alert to monitor the zone at the proper time. Furthermore, Displacement time series analysis of many interferograms (April 2015 to September 2020) using LiCSBAS were performed to investigate the pre-event conditions and precursors of the slopes instabilities., LiCSBAS detects a line-of-sight subsidence velocity of −110 mm/y in the back hillside of Kherba, and high displacement velocity at specific points in Grarem region.
Invited perspectives: The ECMWF strategy 2021–2030 challenges in the area of natural hazards
Authors: Pappenberger Florian , Rabier Florence , Venuti Fabio
Published: July 2021

Abstract. The European Centre for Medium-Range Weather Forecasts (ECMWF) mission is to deliver
high-quality global medium-range numerical weather predictions and monitoring
of the Earth system to its member states. The modelling and forecasting of
natural hazards are an important part of this mission. Challenges in this
area include the integration of innovative observations into the Earth system;
realistic representations of water, energy and carbon cycles; coupling and
initialisation of all Earth system components; adequate representation of
uncertainties; supporting the development of user-specific products to enable
optimal decision-making under uncertainties; and advances in software
engineering. The new ECMWF strategy identified three pillars to sustain its future
development (ECMWF, 2021a): science and technology (world-leading weather and
Earth system science, cutting-edge technology and computational science),
impact (high-quality products fit for purpose, efficient and easy access to
products), and people (inspiring and hiring the best experts). Progress in all
these areas will need enhanced collaboration with member states and partners
across Europe and beyond.
Oil spill model uncertainty quantification using an atmospheric ensemble

Published: July 2021

Abstract. We investigate the impact of atmospheric forcing uncertainties on
the prediction of the dispersion of pollutants in the marine environment.
Ensemble simulations consisting of 50 members were carried out using the
ECMWF ensemble prediction system and the oil spill model MEDSLIK-II in the
Aegean Sea. A deterministic control run using the unperturbed wind of the
ECMWF high-resolution system served as reference for the oil spill
prediction. We considered the oil spill rates and duration to be similar to major
accidents of the past (e.g., the Prestige case) and we performed simulations
for different seasons and oil spill types. Oil spill performance metrics and
indices were introduced in the context of probabilistic hazard assessment.
Results suggest that oil spill model uncertainties were sensitive to the
atmospheric forcing uncertainties, especially to phase differences in the
intensity and direction of the wind among members. An oil spill ensemble
prediction system based on model uncertainty of the atmospheric forcing,
shows great potential for predicting pathways of oil spill transport
alongside a deterministic simulation, increasing the reliability of the
model prediction and providing important information for the control and
mitigation strategies in the event of an oil spill accident.

The anniversary: a screenplay based on an historical crime
Authors: Brien Donna Lee
Published: July 2021

This screenplay is a fictionalised version of the events in Sydney, Australia, in 1894, that

led to the criminal sensation that was known as ‘The Dean Case’. When, on the date of

George Dean’s first wedding anniversary, he was arrested for attempting to murder Mary,

his 20-year-old wife and mother of his 10-week-old baby girl, this case aroused intense

public interest. This screenplay dramatises those events, suggesting both a range of

motivations for George Dean’s crime as well as emphasising Mary Dean’s vulnerability

and bravery in the face of the prolonged domestic abuse she suffered. This screenplay is

a result of sustained enquiry into the following research question: What forms of

biographically-informed writing can express the lives of women who are not well

represented in the documentary archive?

Humanidades Digitales y traducción literaria: inclusividad y transdisciplinaridad en el caso de la traducción de la literatura china al español
Authors: Lei Heyun
Published: July 2021

Desde una perspectiva transdisciplinaria este texto analiza las ventajas que las Humanidades Digitales ofrecen a los traductores literarios, específicamente en el caso de la literatura china y su traducción al español, puesto que lo digital se impone hoy más que nunca como una herramienta imprescindible para la diversificación cultural y el aprendizaje de otras lenguas. Culturas aparentemente lejanas, puestas en contacto, encuentran aspectos comunes que generan aceptación e inclusividad, gracias a la existencia de numerosos recursos digitales que abaratan costos y reproducen la información a gran escala, con alcances espaciales cada vez mayores. Esto último ha generado no solo un creciente interés por las literaturas foráneas que no forman parte del canon occidental sino también ha establecido nuevas metodologías para la traducción literaria.
Iniciativa agencial o espejismo en 'El lago en las pupilas', de Luis Goytisolo
Authors: García Carlos Javier
Published: July 2021

Una pregunta persistente en los estudios literarios y culturales contemporáneos es la relativa a la capacidad de pensar y actuar de modo deliberado. Las páginas que siguen analizan la capacidad agencial de iniciativa en El lago en las pupilas, de Luis Goytisolo. La novela presenta situaciones en las que las emociones, creencias e ilusiones prevalecen sobre hechos constatables a partir de los datos aportados. Llevados por su preocupación de llevar a cabo actos deliberados, los personajes a veces consideran irrelevantes determinadas circunstancias que, si se atiende al texto en su conjunto, cuestionarían su capacidad agencial. De ahí la importancia que tiene estudiar cómo diferentes formas de escritura generan espacios de conocimiento que a la vez crean puntos ciegos y espejismos sobre la propia capacidad de iniciativa.
'Cántico': más allá del aire

El artículo propone una lectura lacaniana de la poesía de Jorge Guillén, ejemplificada en algunos poemas de Cántico. El análisis aboga por una interpretación de la poética guilleniana como expresión del deseo del autor de perseguir la palabra exacta en cada momento creativo. Se materializa así el balance (casi imposible) que la voz poética consigue entre la concepción del ser desde el estadio imaginario, su plasmación literaria a través del orden simbólico, y en busca siempre de la Nada en sus éxtasis del orden real.
La formación de periodistas para la democracia: el papel de la prensa no diaria en España (1975-1982)
Authors: Perales-García Cristina , Luís Rita
Published: July 2021

El ejercicio del periodismo experimentó una profunda y continua renovación en la prensa no diaria española durante los años de la transición política a la democracia. En este artículo se presentan las interpretaciones de esos cambios a partir de la visión de los profesionales que producían los proyectos editoriales. Los resultados han sido obtenidos a partir de grupos focales de discusión con profesionales de la comunicación en activo en publicaciones no diarias de la época (1975-1982). Los focus groups permiten concluir que la formación, muchas veces autodidacta, de los profesionales influye en las consideraciones deontológicas que supone la indistinción entre periodista y militante, característica del periodo de la dictadura y de cambio político. Como consecuencia de ese estilo de periodismo, la prensa no diaria se disputa la hegemonía de los medios del movimiento en la formación de la opinión pública. Sin embargo, según estos testimonios, la mayoría de los proyectos editoriales no diarios con objetivos políticos no sobreviven a la llegada de una prensa diaria profesionalizadora después de 1976, ejercida mayormente por profesionales formados en escuelas y universidades de Periodismo.
Cívico, profesional y amateur: perfil ético del periodismo ciudadano en perspectiva interdisciplinar

Como alternativa al enfoque instrumental con el que ha sido abordado en la literatura académica, desde la perspectiva del estudio la aportación del periodismo ciudadano es el desarrollo de una ética propia producto de la apropiación de prácticas con origen en el periodismo que migran a la vida cotidiana; dicha ética no es estrictamente profesional sino un sistema híbrido de conceptos y valores ciudadanos. Con una perspectiva interdisciplinar y diseño mixto de tipo descriptivo, el artículo plantea una aproximación al perfil del periodismo ciudadano en la frontera noroeste de México, a través del análisis de su ejercicio ético-profesional y la diferenciación en la esfera pública. En los resultados, el análisis de conglomerados y el uso de la Teoría Fundamentada arrojan la combinación de rasgos cívicos, profesionales y amateur. En ambos casos los perfiles se acercan a los sectores vulnerables y mantienen distancia del interés económico y el gobierno.
La ausencia de perspectiva de género en los procesos de búsqueda y selección de las fuentes expertas que comparecen en televisión
Authors: Campos Rueda Marcela , Herrera Damas Susana
Published: July 2021

El presente trabajo explora los procesos de búsqueda y selección de fuentes expertas en los programas informativos de televisión en España desde una perspectiva de género. Se abordan por tanto dos temas de gran relevancia presentes tanto en la agenda académica como política: la paridad de género y el rol de las fuentes expertas en un contexto informativo de creciente complejidad. Comprender las rutinas profesionales y cómo impactan en la selección de fuentes expertas es un primer paso para abordar un tema que no ha sido suficientemente estudiado. La investigación se informa a partir de una encuesta (n=125) y entrevistas en profundidad (n=6) con productores y productoras de programas informativos. Los resultados nos llevan a concluir que los procesos de búsqueda y selección de expertos no se hacen desde una perspectiva de género y que la paridad entre fuentes no se contempla como un indicador de la calidad de la información.
La sección “Tendencias” en YouTube en España durante las primeras semanas de la pandemia de Covid-19: visibilidad de las industrias culturales frente a los youtubers
Authors: Pérez Rufí José Patricio , Castro-Higueras Antonio
Published: July 2021

Este trabajo analiza la sección “Tendencias” en la plataforma VoD YouTube en España durante las dos semanas posteriores inmediatas a la declaración del estado de alarma por el gobierno español. Los objetivos son identificar las modificaciones en los contenidos de “Tendencias” para adecuarse al estado de alarma y reconocer la mayor o menor visibilidad de contenidos generados por industrias culturales o usuarios. Aplicamos un análisis descriptivo y cuantitativo sobre una muestra de 84 vídeos (condicionada por el acceso a la información). Los resultados permiten identificar una adaptación del algoritmo de “Tendencias”: los vídeos de carácter informativo creados por usuarios acerca del coronavirus o sobre cuestiones adyacentes son progresivamente ocultados para dar prioridad a los vídeos producidos por medios de comunicación. YouTube apuesta preferentemente por dar mayor visibilidad a los contenidos de entretenimiento producidos por las industrias culturales. YouTube interviene en la visibilidad de contenidos desde su responsabilidad social.
Análisis de las revistas mejor indexadas en comunicación en España. Mapa de la difusión de los artículos vinculados a proyectos I+D+i en revistas españolas desde 2007 hasta 2018

Published: July 2021

Se evalúan las revistas españolas mejor indexadas en comunicación de la década 2007-2018 como difusoras de la investigación de los proyectos I+D y se constata la regionalización variable, es decir, la difusividad de las fuentes investigadoras en cada una de ellas. Este trabajo adelanta algunos resultados del estudio MapCom: evalúa hasta qué punto la proporción de la presencia de estos artículos derivados de la investigación puede relacionarse con la posición que ocupan las revistas que los publican entre las mejor indexadas en Comunicación y observa, en segundo lugar, la geografía variable de la investigación que se configura en relación con las distintas revistas en las que se difunden sus resultados. Se concluye que existe una convergencia entre la publicación de artículos I+D y la mejora en la indexación de las revistas y, por otra parte que, a la hora de difundir la investigación en Comunicación, se regionaliza la publicación de artículos según cuáles sean las revistas anfitrionas.
Plataformas y política audiovisual: Netflix en España
Authors: García Leiva María Trinidad , Hernández Prieto Marina
Published: July 2021

El objetivo de este artículo es reflexionar, en el ámbito de las políticas audiovisuales y en clave de diversidad, sobre el impacto de las plataformas trasnacionales que ofrecen audiovisual de pago bajo demanda en España. Para ello se describen y analizan las reacciones que las mismas han generado desde su desembarco, prestando especial atención a la empresa Netflix. Partiendo de un análisis documental y bibliográfico crítico, tales reacciones se estudian a partir del posicionamiento adoptado por los principales agentes interpelados y/o afectados. Los resultados revelan una falta generalizada de reflexión y acción por parte de la clase política y la Administración pública; una actitud inicialmente defensiva de los operadores de servicios audiovisuales existentes; un posicionamiento desigual y fragmentado desde el ámbito profesional; y una actitud garantista por parte de las entidades de gestión de derechos del sector, así como de las pocas iniciativas provenientes de la sociedad civil.

This study aimed to characterize the prevalence, mean abundance, and mean intensity of potential fish-borne zoonotic nematode larvae infecting the predator fish Hoplias aff. malabaricus from the Tapajós River, in the municipality of Santarém, in the Brazilian Amazon. After capture, the specimens of H. aff. malabaricus were analyzed for infection by Contracaecum sp. and Eustrongylides sp. third-stage larvae, and the prevalence, mean abundance, and mean intensity were calculated. A literature search was carried out to clarify the relationship between these indicators and eventual human cases of infection in the Amazon region. Third-stage larvae of nematodes of the Contracaecum and Eustrongylides genera were found in the specimens of H. aff. malabaricus sampled from the Tapajós River. The prevalence of Contracaecum larvae was 100%, while its mean abundance and mean intensity were both 54.8 larvae/fish. The prevalence of Eustrongylides larvae was 62.9%, and its mean abundance and mean intensity were 1.8 and 2.8 larvae/fish, respectively. Despite the high prevalence and intensity values, there are no cases of human infection by these nematode larvae in the Brazilian Amazon reported. The absence of human infections by these nematode larvae in the Brazilian Amazon despite the high prevalence/intensity of Contracaecum and Eustrongylides larvae and the high consumption of fish in the region, is most probably due to the fact that the local populations do not eat raw or undercooked fish. However, it is noteworthy that the absence of zoonotic cases in the region is based only on the examination of the available published papers. A better knowledge of the situation would require surveying hospitals and clinics, and data from the region’s medical treatment facilities. However, the authors consider that cases of human infection, if any, are extremely rare, mainly due to the eating habits of the local population.

A poesia prismática de Manuel Bandeira
Authors: Donizeti Pires Antônio
Published: July 2021

Manuel Bandeira (1886-1968) é dos mais destacados e amados poetas líricos do Brasil, cujas atividades em prol da nova estética modernista incluem vários campos da arte, da cultura e do ensino. Estreou em 1917 com A cinza das horas, vincado por ressaibos parnaso-simbolistas, mas logo se tornou um dos ícones do Modernismo, bastante respeitado pelos artistas da Semana de Arte Moderna de São Paulo (1922). Ao fim de uma produtiva carreira poética, constata-se que a melhor herança de Bandeira é a universalidade, pois transitou pelas formas e técnicas tradicionais e vanguardistas e explorou temas que abarcam a tradição lírica e aqueles que ressaltam o cotidiano e o desconcerto do homem moderno na grande cidade.
The Reversal of Impairments of PPE: A Test of Fair Value Accounting
Authors: Campa Domenico , Cao TongYu , Donnelly Ray
Published: July 2021

This study examines if the reversal of impairments allowed by IAS 36 as undertaken by UK-quoted companies can be justified as unbiased adjustments to reflect the fair value of the property, plant and equipment assets to which they pertain. We test if the reversals are reflected in the change in stock market prices in an indirect test. We also employ a direct test to establish if the reversals are positively related to changes in subsequent operating performance. Our results suggest that the reversals of impairments are positively related to changes in future performance. Only those reversals that are undertaken when the pre-reversal net income is not negative are reflected in stock market returns. This is somewhat justified by the finding of a differential relation between the ability of the reversals to predict future operating performance and whether the firm is profitable pre-reversal or not. We argue that the results based on the direct test are more convincing and that our results support the decision of the IASB to allow the reversal of impairments.

Background: Chronic kidney disease (CKD) is characterized by structural and functional disorder of the kidney with irreversible and gradual characteristics with one of the modalities of renal replacement therapy such as hemodialysis (HD). The role of inflammation in HD patients by uremic toxin and dialysis can be assessed by the marker of High Sensitive C Reactive Protein (HsCRP). Several studies have examined the relationship between HsCRP and red cell distribution width (RDW) in regular HD patients which leads to increase patient morbidity and mortality, but until now, there has been no study in Indonesia regarding the correlation between HsCRP and RDW in regular HD patients. This study aims to determine the correlation HsCRP as a marker of inflammation and RDW values in regular HD patients.
Methods: This is a cross-sectional study in Regular HD patients at Dialysis Unit-H. Adam Malik General Hospital. A total of 20 subjects were included. Bivariate and multivariate analysis was conducted to analyze the relationship of HsCRP, ureum, creatinin, hemoglobin, and eGFR to RDW.
Results: There were 20 Regular HD patients analyzed. The proportion of patients with increased RDW was 80%. In pearson correlation test, there is a strong correlation between HsCRP and RDW (r= 0.667, p<0.001).
Discussion: Majority of regular HD patients at H. Adam Malik General Hospital were assessed with increased RDW. Pearson correlation analysis revealed HsCRP was significantly associated with RDW.
Conclusion: Increased RDW was found in 80% of regular HD patients at H. Adam malik General Hospital. From pearson correlation analysis, we found HsCRP was significantly associated with RDW.

Keywords: inflammation, high sensitive c reactive protein, red blood cell distribution width, regular hemodialysis.

Authors: Fernando Arnaldi , Gatot Dairion , Sitepu Yan Indra Fajar
Published: July 2021

Introduction: Breast cancer is formed from breast cells, either lobule or duct epithelium, which undergoes uncontrolled growth and development. The therapy of breast cancer to reduce mortality and morbidity can be done by way of surgery, chemotherapy, and radiotherapy. Doxorubicin chemotherapy is a therapeutic option to kill cells directly or by stopping the cell division based on the tumor pathogenesis.
Method: This research is a paired numerical comparative analytical study using a retrospective cohort approach. This study was conducted on 56 breast cancer patients to see the differences in myelosuppression before and after doxorubicin chemotherapy at H. Adam Malik General Hospital Medan from January-December 2019. The data were obtained through recording the routine blood laboratory results listed in the patient's medical record and were analyzed with dependent t-test by using SPSS. The difference is significant if p <0.05.
Result: The results showed that the average age of the research subjects was 40.79 years, 28 patients (50%) graduated from high school, 38 patients (67.9%) did not work and 53 patients (94.6%) had marital status. In a significant myelosuppression difference, anemia occured with chemotherapy Hb levels of 8.48 ± 1.09, the Hb difference in Hb prior to and after doxorubicin chemotherapy obtained a mean of 1.28 with p value <0.001.
Conclusion: Based on the demographic characteristics of patients with breast cancer, it was found that the mean age of patients with breast cancer in women was 46.79 years; most of the subject’s education level was highschool, unemployed and married status. There was a very significant difference between the subject's Hb level and breast cancer before and after doxorubicin chemotherapy.
