“Entre Lobo e Cão” e “Dissolução”: uma leitura Orwelliana da abertura de Claro Enigma
Authors: Almeida Cleber Ranieri Ribas de
Published: May 2023

A abertura do livro Claro Enigma (1951), de Carlos Drummond de Andrade, inicia-se com um pórtico enigmático intitulado “Entre Lobo e Cão”, seguido do poema “Dissolução”. A tese mais aceita entre os críticos é de que “Entre Lobo e Cão” seria um intertexto com os versos de um poema de Sá de Miranda, assim como “Dissolução” evocaria o pessimismo e o imobilismo do poeta. Neste artigo pretendo demonstrar que a correta interpretação do título da secção estaria numa crônica do próprio Drummond intitulada “Para Quem Goste de Cão” (1947), a qual, em geral, é literalmente lida como um panfleto em defesa dos cães. Nossa tese, contudo, é de que a crônica deve ser lida como uma alegoria política orwelliana na qual Drummond compara poetas inautênticos a cães domésticos, lobos a poetas autênticos, escritores a crianças carentes e editores a donos de cães de luxo. Os personagens teromorfos são transfigurações dos personagens que protagonizaram o Segundo Congresso da Associação Brasileira de Escritores (ABDE). Por fim, lançaremos mão de uma interpretação contextual do poema “Dissolução”.

Published: May 2023

Introduction and Aim: Vitiligo is a hypomelanotic, idiopathic disease influencing entire pigmentary system which includes stria vascularis of internal ear described by depigmented patches in the skin because of absence of melanin and functioning melanocytes in the epidermis. The aim of this study was to assess the audiological irregularities by assessing the brain stem auditory evoked potential in vitiligo patients and comparing with the healthy controls.
 
Materials and Methods: Forty clinically confirmed vitiligo patients of 20 to 40 years of both genders, with or without therapy were enlisted from the Dermatology and cosmetology outpatient clinics, Government Stanley Hospital. Forty controls with similar ages and genders were chosen. The Neuro perfect Medicaid polyrite instrument was used in recording Brainstem Evoked Reaction Audiometry (BERA) in both vitiligo individuals and controls. Inter-Peak Latencies (IPL) and Absolute Wave Latencies (AWL)were measured and analysed by using SPSS version 17. Student's independent 't' test was done for comparing the groups.
 
Results: AWL and IPL of the two ears were measured and both were compared in the study and control groups. In the left ear, AWL III of study subjects had a significant increase 3.34+0.16 than that of controls 3.27+0.19; IPL I-III also significantly increased in the study subjects 1.91+0.16 than the controls 1.77+0.17. In the right ear, AWL III of study subjects had a significant increase 3.18+0.17 than the controls 3.06+0.15; IPL I-III also significantly increased in the study subjects 1.79+0.17 than the controls 1.64+0.16.
 
Conclusion: BERA findings were abnormal in clinically asymptomatic research subjects, suggesting that this test should be included in the routine follow-up of vitiligo patients to detect audiological subclinical involvement.

Predisposition to diabetes is attributed to a large number of genes. TCF7L2 is one of the most significant candidate genes among them, and it is crucial for beta-cell activity and blood glucose regulation. According to previous research, TCF7L2 has been implicated in T2DM in various Indian tribes. Many studies have discovered a link between TCF7L2 gene variations and vulnerability to T2DM. These results suggest that changes in TCF7L2 expression are not only associated with insulin resistance but also with risk for genotypes connected to poor beta cell activity. TCF7L2 drives the conventional Wnt signalling pathway and functions as a nuclear ligand for beta catenin. Wnt signalling is necessary for intestinal endocrine L-cells to emit GLP-1 (glucagon-like peptide-1). As a result, a blockage in this route would cause less GLP-1 to be released, which might have an impact on the release of insulin after meals contributing to T2DM as a result. The molecular processes through which the TCF7L2 gene increases the susceptibility of T2DM will therefore be of significant interest, as will the identification of possible therapeutic targets that may be employed to treat and prevent the illness as a result of the gene variations.

Published: May 2023

Introduction and Aim: Hypothyroidism is an endocrine disorder with a high prevalence worldwide in the adult population. Due to the thyroid hormone’s widespread role in controlling metabolic processes to permissive action on the heart, patients with hypothyroidism suffer from a significant chance of acquiring cardiac autonomic dysfunction which further deteriorates the prognosis. Heart rate Variation analysis can be a possible way to detect this autonomic dysfunction early and may help in patient care. This study aims to assess Heart Rate Variability (HRV) parameters in untreated overt hypothyroid patients and compare the parameters of heart rate variability test with an age and sex-matched healthy control group.
 
Materials and Methods: With the permission from the institutional ethics committee, 50 untreated hypothyroid patients are collected from the endocrine outpatient department and 50 healthy age, sex, and matched individuals are taken, maintaining proper inclusion and exclusion criteria. HRV analysis data is collected in both time and frequency domains in both groups and compared using statistical tools.
 
Results: In our research, it is seen that compared to healthy control group, untreated hypothyroid patients have a significant alteration in the following parameters - SDNN (p<0.005) and RMSSD (p<0.009) in the time domain and LF (nu), LF (%), HF (%), LF/HF, HF (nu)[p<0.05] in the frequency domain.
 
Conclusion: Due to several alterations in HRV parameters indicating sympathovagal disbalance in the hypothyroid patients, it can be concluded that untreated hypothyroid patients are prone to develop cardiovascular autonomic dysfunction and HRV analysis can be a possible way to detect it early.

Published: May 2023

El cuidado otorgado a los niños tiene un lugar importante para la historia de la enfermería en México; desde la cultura azteca, se les preparaba para sus actividades futuras en el calmecac, telpuchcalli y culcalli, mientras que durante la época precortesiana la principal figura era la tlamatqui-ticitl (partera), responsable de atender a las embarazadas y a sus niños durante los primeros meses.
Posteriormente se funda el Hospital de la Inmaculada Concepción (hoy Hospital de Jesús), así como centros de protección para niños indígenas, mestizos y criollos a cargo de monjes agustinos, franciscanos, dominicos y jesuitas. Vasco de Quiroga fundó una casa cuna, motivo por el cual fue llamado “protector del niño indio de América”, y el arzobispo Francisco de Lorenzana y Butrón fundó la Casa de Niños Expósitos de la ciudad de México.
Durante el Imperio de Maximiliano de Habsburgo, la emperatriz Carlota logró el establecimiento de una “casa de maternidad e infancia”. Tiempo después se planea el primer centro de higiene infantil y se funda la Casa Cuna de Coyoacán.
El 30 de abril de 1943 se funda oficialmente el Hospital Infantil de México Federico Gómez (HIMFG) e inician los cursos de enfermería pediátrica, que con el tiempo cambian para constituir la especialidad en Enfermería infantil y dar origen a la especialidad en Neonatología y Oncología.

Abstract. The Geoengineering Model Intercomparison Project (GeoMIP) is a coordinating framework, started in 2010, that includes a series of standardized climate model experiments aimed at understanding the physical processes and projected impacts of solar geoengineering. Numerous experiments have been conducted, and numerous more have been proposed as “test-bed” experiments, spanning a variety of geoengineering techniques aimed at modifying the planetary radiation budget: stratospheric aerosol injection, marine cloud brightening, surface albedo modification, cirrus cloud thinning, and sunshade mirrors. To date, more than 100 studies have been published that used results from GeoMIP simulations. Here we provide a critical assessment of GeoMIP and its experiments. We discuss its successes and missed opportunities, for instance in terms of which experiments elicited more interest from the scientific community and which did not, and the potential reasons why that happened. We also discuss the knowledge that GeoMIP has contributed to the field of geoengineering research and climate science as a whole: what have we learned in terms of intermodel differences, robustness of the projected outcomes for specific geoengineering methods, and future areas of model development that would be necessary in the future? We also offer multiple examples of cases where GeoMIP experiments were fundamental for international assessments of climate change. Finally, we provide a series of recommendations, regarding both future experiments and more general activities, with the goal of continuously deepening our understanding of the effects of potential geoengineering approaches and reducing uncertainties in climate outcomes, important for assessing wider impacts on societies and ecosystems. In doing so, we refine the purpose of GeoMIP and outline a series of criteria whereby GeoMIP can best serve its participants, stakeholders, and the broader science community.

Abstract. The Chaos Canyon landslide, which collapsed on the afternoon of June 28th, 2022 in Rocky Mountain National Park presents an opportunity to evaluate instabilities within alpine regions faced with a warming and dynamic climate. Video documentation of the landslide was captured by several eyewitnesses and motivated a rapid field campaign. Initial estimates put the failure area at 66,630 m2, with an average elevation of 3,555 m above sea level. We undertook an investigation of previous movement of this landslide, measured the volume of material involved, evaluated the potential presence of interstitial ice/snow within the failed deposit, and examined potential climatological forcings at work in causing the collapse of the slope. Satellite radar and optical measurements were used to measure deformation of the landslide in the years leading up to collapse. From 2017 to 2019, the landslide moved ∼5 m yr-1, accelerating to 17 m yr-1 in 2019. Movement took place through both internal deformation and basal sliding. Climate analysis reveals the collapse took place during peak snowmelt, and 2022 followed 10 years of higher than average positive degree day sums. We also made use of slope stability modeling to test what factors controlled the stability of the area. Models indicate even a small increase in the water table reduces the Factor of Safety to <1, leading to failure. Material volumes were estimated using Structure from Motion (SfM) models incorporating photographs from two field expeditions on July 8th, 2022 – 10 days after the slide. Detailed mapping and SfM models indicate ∼ 1,258,000 ± 150,000 m3 of material was deposited at the slide toe and ∼1,340,000 ± 133,000 m3 of material was evacuated from the source area. Our holistic approach to the collapse of the Chaos Canyon landslide provided an opportunity to examine a landslide that may be representative of future dynamic alpine topography, wherein failures becomes more common in a warming climate.
Using multiple hydrological data sources to reduce uncertainty in soil drainage modeling
Authors: Jiang Yefang ,   Yefang Jiang
Published: May 2023

Soil drainage flux is crucial for determining agrochemical loading and groundwater recharge. Because soil drainage is difficult to measure, it is typically predicted using soil moisture models. However, different soil moisture models have been shown to produce different drainage values although they all respected the same soil measurements well, leading to a non-uniqueness problem. To address this issue, this study used groundwater level, stream flow, and tile drainage measurements along with soil moisture data to constraint soil drainage estimation through a coupled soil and groundwater modeling framework in the Cross River watershed in Prince Edward Island, Canada. A 1D Richards equation model, LEACHM, was developed to predict soil drainage and calibrated using soil moisture data. A 3D watershed-scale MODFLOW model was built and calibrated against groundwater level data. The two models were loosely coupled using the soil drainage predicted by LEACHM as recharge. Forward coupled LEACHM and MODFLOW simulations were performed until simulated daily soil moisture, groundwater level, baseflow, and tile drainage values simultaneously matched the 2011–2014 observed values within prescribed error ranges by fine tuning the hydraulic parameters in coupled models. The coupled models were then verified using 2015–2016 data. The resulting LEACHM simulations matched the soil moisture data with less than 15% error, and MODFLOW simulations matched the groundwater level and base flow data, except for a few short periods when LEACHM overestimated soil drainage under deep snow cover. Although the timing of simulated soil drainage corresponded with the occurrence of tile drainage, the simulated soil drainage was generally higher than the tile drainage, which is considered reasonable because tiles intercept only a portion of the overall soil drainage. This exercise demonstrates that the coupled modeling respected multiple hydrological data sources instead of soil moisture alone, and thus enhanced soil moisture estimation.
The wave-age dependent stress parameterization (WASP) for momentum and heat turbulent fluxes at sea in SURFEX v8.1

Published: May 2023

Abstract. A widely applicable parameterization of turbulent heat and momentum fluxes at sea has been developed for the SURFEX v8.1 surface model. This wave-age dependent stress parameterization (WASP) combines a close fit to available in situ observations at sea up to wind speed of 60 m s-1 with the possibility of activating the impact of wave growth on the wind stress. It aims in particular at representing the effect of surface processes that depend on the surface wind according to the state of the art. It can be used with the different atmospheric models coupled with the surface model SURFEX, including the CNRM-CM climate model, the operational (numerical weather prediction) systems in use at Météo-France and the research model Meso-NH. Designed to be used in coupled or forced mode with a wave model, it can also be used in atmosphere-only configuration. It has been validated in several case studies covering different surface conditions known to be sensitive to the representation of surface turbulent fluxes: i) the impact of a Sea Surface Temperature (SST) front on low-level flow by weak wind; ii) the simulation of a Mediterranean heavy precipitating event where waves are known to influence the low-level wind and displace precipitation; iii) several tropical cyclones; and iv) a climate run over 35 years. It shows skills comparable to or better than the different parameterizations in use in the SURFEX v8.1 so far.
Comparison of optimal power production and operation of unmoored floating offshore wind turbines and energy ships
Authors: Connolly Patrick , Crawford Curran
Published: May 2023

Abstract. As the need to transition from global reliance on fossil fuels grows, solutions for producing green alternative fuels are necessary.
These fuels will be especially important for hard-to-decarbonize sectors such as shipping.
Mobile offshore wind energy systems (MOWESs) have been proposed as one such solution.
These systems aim to harness the far-offshore wind resource, which is abundant and yet untapped because of installation and grid-connection limitations.
Two classes of MOWES have been proposed in the literature: unmoored floating offshore wind turbines (UFOWTs) and energy ships (ESs).
Both systems operate as autonomous power-to-X (PtX) plants, powered entirely by wind energy, and so can be used to produce synthetic green fuels such as hydrogen or ammonia, or for other energy-intensive applications such as direct air carbon capture.
The two technologies differ in form; UFOWTs are based on a conventional FOWT but include propellers in place of mooring lines for course keeping, while ESs operate like a sailing ship and generate power via hydro-turbines mounted on the underside of the hull.
Though much research and development is necessary for these systems to be feasible, the promise of harnessing strong winds far offshore, as well as the potential to avoid siting regulatory challenges, is enticing. This paper develops models of each MOWES concept to compare their power production on a consistent basis.
The performance of the technologies is examined at steady-state operating points across relative wind speeds and angles.
An optimization scheme is used to determine the values of the control variables which define the operating point for each set of environmental conditions.
Results for each model show good agreement with published results for both UFOWTs and ESs.
Model results suggest that UFOWTs can generate more power than ESs under ideal environmental conditions but are very sensitive to off-design operating conditions.
In above-rated wind speeds, the UFOWT is able to produce as much power as a conventional, moored FOWT, whereas the ES cannot, since some power is always consumed to spin the Flettner rotors.
The models developed here and their results may both be useful in future works that focus on the routing of UFOWTs or holistically designing a mobile UFOWT.
Although differences in the performance of the systems have been identified, more work is necessary to discern which is a more viable producer of green electrofuels (e-fuels).
¿Cómo planifica y revisa el alumnado de primaria? Un estudio de caso de una tarea de escritura colaborativa
Authors: López-Flamarique Maite , Aznárez-Mauleón Mónica , García-del-Real Isabel
Published: May 2023

Las tareas de producción textual colaborativa constituyen un marco adecuado para el estudio de los procesos cognitivos de escritura. Este trabajo, de tipo descriptivo y cualitativo, utiliza datos provenientes de la escritura colaborativa para averiguar el modo como el alumnado de primaria lleva a cabo los procesos de planificación y de revisión textuales, en concreto, cuándo lo hace y a qué operaciones propias de estos procesos presta atención. Para ello, se grabaron y analizaron las interacciones orales de nueve parejas de estudiantes de primaria que escribieron fábulas colaborativamente en español L1. Los resultados muestran que la planificación está fundamentalmente dirigida a la generación de ideas y que esta se produce principalmente durante la escritura. En cuanto a la revisión, se observa que el alumnado revisa diversos aspectos de la escritura durante la textualización, pero solo dos parejas realizan una revisión final, la cual se centra exclusivamente en aspectos ortográficos. Esta investigación muestra el comportamiento del alumnado durante la escritura colaborativa y puede orientar la enseñanza-aprendizaje de la escritura menos centrada en el producto y más acorde con las necesidades del alumnado.
Integración de las tecnologías digitales en las clases de Lengua y Literatura: categorización a partir de las prácticas letradas en la educación secundaria
Authors: Godoy Lucía Francisca
Published: May 2023

En el presente artículo se presenta una categorización para dar cuenta de los modos de incorporación de las tecnologías digitales en las clases de Lengua y Literatura. Desde un enfoque sobre las prácticas de literacidad, se proponen cuatro categorías que permiten encuadrar los distintos usos de las tecnologías digitales en las aulas. La categorización fue elaborada a partir de las observaciones realizadas durante un trabajo de campo de carácter etnográfico en clases de nivel secundario en el Gran Buenos Aires (Buenos Aires, Argentina). La propuesta categoriza en cuatro los modos de incorporación de las tecnologías digitales en las clases de Lengua y Literatura: (a) como medio de comunicación, entre estudiantes y docentes; (b) como soporte para el desarrollo de contenidos; (c) como herramienta para la ejercitación y la resolución de actividades; y (d) como recurso para la creación y la experimentación en la producción de materiales multimodales. En el artículo se presentan y explican cada una de estas categorías y se las ilustra con escenas auténticas recogidas durante el trabajo de campo.
Lectura literaria y canon en Educación Secundaria desde el paradigma del pensamiento del profesorado. Estado de la cuestión
Authors: López Rodríguez Rosa María
Published: May 2023

Este trabajo forma parte de una investigación más amplia realizada desde un enfoque cualitativo, de carácter etnográfico y a medio camino entre los paradigmas fenomenológico y crítico, cuyo objetivo es analizar las concepciones  del profesorado de secundaria en torno a la educación literaria, sus estrategias de aprendizaje, sus prácticas de enseñanza y su reflejo en las dinámicas de aula. En este artículo en particular se aborda el estado de una de las cuestiones que han suscitado y suscitan en la actualidad mayor debate en el ámbito de la didáctica de la literatura y entre el profesorado: qué obras constituyen el itinerario apropiado para una educación literaria que desarrolle el gusto por la lectura y lo proyecte más allá de las aulas, es decir, la composición del corpus o canon formativo de secundaria. Para ello, se ha hecho una revisión de algunos de los trabajos que se han ocupado del concepto de canon desde el último tercio del siglo XX, junto con otras investigaciones sobre las creencias del profesorado de secundaria en relación al corpus formativo de la educación literaria. Asimismo, se mencionan las principales líneas que orientan este objeto de estudio en la nueva normativa de enseñanza. Los resultados que se obtienen de esta revisión apuntan a un acuerdo generalizado para ampliar y diversificar el corpus de textos y sus formatos, actualizar los géneros desde una perspectiva multimodal, y normalizar las prácticas sociales de lectura literaria dentro de las aulas.

The relevance of the article is conditioned upon socio-cultural factors, in particular the problem of demographic ageing of the population, as a result of which there is a need for new research on the specific features of the physical and mental state of health of elderly people in order to develop an appropriate level of assistance to them based on causal relationships. The purpose of the scientific article is a theoretical analysis of personal alienation as one of the factors in the occurrence of hypochondriac disorders in the elderly. The study of the chosen problem allowed applying general research methods, namely system analysis, synthesis, generalisation and systematisation. The article provides a theoretical analysis of the problem of personal alienation as a factor in the occurrence of hypochondriac disorders in the elderly. The article reveals the specific features of experiencing personal alienation in the elderly, its socio-psychological characteristics and causes of development. It was found out that the phenomenon of alienation in older people is based on the emotional and personal aspects, as a result of which the probability of hypochondriac disorders increases. A theoretical justification of the semantic load of the concept of hypochondriac disorders is given, the attributes of their occurrence and development in old age are considered, including the types of the most common diseases, such as cardiovascular diseases, from the list of hypochondriac disorders. Among the main manifestations of hypochondria in the elderly, increased anxiety, depression, apathy, lack of trust, sentimentality, frustration, despondency, fear of the future, bad mood, etc. were found. The obtained results of the study provide an exhaustive analysis of the chosen problem, which is the scientific value of the work and also become the theoretical basis for the development of further practical methods for preventing the appearance of hypochondriac disorders in the elderly

Purpose: The aim of the study was to measure and compare the release of fluoride ions from three bioactive restorative materials used for restorations in primary dentition - conventional GIC Fuji IX GP Extra, compomer Dyract and giomer Beautifil II. Materials and methods: 20 samples with a diameter of 6 mm and a thickness of 2 mm were made from the tested materials. At the beginning of the test, all samples were immersed in 5 ml of deionized water and placed in an incubator for 24 hours at 37°C ± 0.5°C. After 24 hours, the concentration of fluoride ions in the medium was measured with an ion-selective electrode for fluorides connected to an ion meter. During this time, the removed cylindrical samples were washed with fresh deionized water, dried, and transferred to new vials with 5 ml of fresh deionized water. The described procedure was repeated every day for a week and then on the 14th, 21st and 28th days. Results: GIC outperformed compomer and giomer in terms of fluoride ions release for all time intervals with a statistically significant difference. The difference between compomer and giomer was not reliable, but compomer demonstrated higher values ​​for all time intervals. Conclusion: All studied materials released fluoride ions during the entire experimental period, with the highest concentrations being recorded on the first day of the study. GIC outperformed compomer and giomer many times in terms of fluoride release for all time intervals.

Authors:   The Bucharest University of Economic Studies, Bucharest, Romania, STOICA Mihai
Published: May 2023

The intensification of consumers' concerns for personal health protection has conducted, among other things, to a change in purchasing behavior toward organic food. However, emerging markets are still characterized by low levels of organic food consumption. Therefore, companies present on this market are trying to find new ways to boost the consumption of organic food, along with placing their brands in the most favorable positions in the minds of consumers. This study aims to identify the positioning bases that companies want to highlight in order to outline the desired position of their brand. To achieve this goal, a qualitative research was conducted among producers/processors, distributors/importers, and retailers having organic food brands in their portfolio. The results of the research showed the focus of the companies on highlighting the attributes related to the product characteristics and the personal green benefits, at the expense of environmental, emotional, and symbolic benefits. Positioning bases related to consumption occasions, brand values, and association with fictional characters or celebrities play a secondary role in supporting the brand position. The research contributes to the classification and conceptualization of specific positioning bases for organic food brands, providing an overview of this topic at the supply chain level.

Published: May 2023

The presence of vegetable oils in the pharmaceutical and cosmetic industries boosts their production and commercialization, maximizing the economic potential, however to increase profits, vegetable oils with high added value are the target of adulteration practices. This negatively affects the quality of the product and compromises the bioactive properties of these oils. The objective of this study was to build partial least squares regression models to identify baru oil and soursop oil samples adulterated with soybean oil. For data collection the oils samples were characterized using portable near-infrared spectrometer and Fourier-transform infrared spectrometer. These techniques were chosen because both provide information about the functional groups of chemical compounds, however portable equipment, being cheaper, presents signals with lower spectral resolution. Thus, the objective of the work is also to verify if the results using both equipment are similar. The developed regression models were effective; however, the near-infrared technique presented some limitations in the identification of soursop oil. This is because for the construction of his model it was necessary to use a smaller number of variables and levels of adulteration. Nevertheless, high R² values and relatively low errors were obtained for all models, making it possible to identify the adulteration.
