Abstract. Formation of atmospheric ice plays a crucial role in the microphysical evolution of mixed-phase and cirrus clouds and thus climate. How aerosol particles impact ice crystal formation by acting as ice-nucleating particles (INPs) is a subject of intense research activities. To improve understanding of atmospheric INPs, we examined daytime and nighttime particles collected during the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign conducted in summer 2017. Collected particles, representative of a remote marine environment, were investigated for their propensity to serve as INPs in the immersion freezing (IMF) and deposition ice nucleation (DIN) modes. The particle population was characterized by chemical imaging techniques such as computer-controlled scanning electron microscopy with energy dispersive X-ray analysis (CCSEM/EDX) and scanning transmission X-ray microscopy with near-edge X-ray absorption fine structure spectroscopy (STXM/NEXAFS). Four major particle-type classes were identified where internally mixed inorganic-organic particles make up the majority of the analyzed particles. Following ice nucleation experiments, individual INPs were identified and characterized by SEM/EDX. The identified INP types belong to the major particle-type classes consisting of fresh sea salt with organics or processed sea salt containing dust and sulfur with organics. Ice nucleation experiments show IMF events at temperatures as low as 231 K including the subsaturated regime. DIN events were observed at lower temperatures of 210 to 231 K. IMF and DIN observations were analyzed with regard to activated INP fraction, ice-nucleation active sites (INAS) densities, and water activity-based immersion freezing model (ABIFM) yielding heterogeneous ice nucleation rate coefficients. Observed IMF and DIN events of ice formation and corresponding derived freezing rates demonstrate the marine boundary layer aerosol particles can serve as INPs under typical mixed-phase and cirrus clouds conditions. The derived IMF and DIN parameterizations allow for implementation in cloud and climate models to evaluate predictive effects of atmospheric ice crystal formation.
Characteristics of the natural radioactivity of the underground laboratories in the Baltic Sea Region participating in the BSUIN and EUL projects
Authors: Szkliniarz Katarzyna
Published: January 2022

Abstract. Underground laboratories (ULs) offer more and more opportunities
for their usage. Still, one of the most critical parameters describing ULs
is their natural radioactivity. Therefore, the article compares the six ULs
of the BSUIN (Baltic Sea Underground Innovation Network) and EUL (Empowering
Underground Laboratories Network Usage) projects regarding their natural
radioactivity. Measurements include in situ and laboratory analysis of the
collected rock and water samples, using various nuclear spectrometry
techniques. The lowest level of natural radioactivity characterizes salt
deposit is in the Conceptual Lab development co-ordinated by KGHM Cuprum
R&D centre.
Retrieval of ice water path from the FY-3B MWHS polarimetric measurements based on deep neural network
Authors: Wang Wenyu , Wang Zhenzhan , He Qiurui , Zhang Lanjie
Published: January 2022

Abstract. Ice water path (IWP) is an important cloud parameter in atmospheric radiation, and there are still great difficulties in retrieval. The artificial neural network is a popular method in atmospheric remote sensing in recent years. This study presents a global IWP retrieval based on deep neural networks using the measurements from Microwave Humidity Sounder (MWHS) onboard the FengYun-3B (FY-3B) satellite. Since FY-3B/MWHS has quasi-polarization channels at 150 GHz, the effect of polarimetric radiance difference (PD) is also investigated. A retrieval database is established using collocations between MWHS and CloudSat 2C-ICE. Then two types of networks are trained for cloud scene filtering and IWP retrieval, respectively. For the cloud filtering network, using IWP of 10 g/m2 and 100 g/m2 as the threshold show the filtering accuracy of 86.48 % and 94.22 % respectively. For the IWP retrieval network, different training input combinations of auxiliary information and channels are compared. The results show that the MWHS IWP retrieval performs well at IWP > 100 g/m2. The mean and median relative errors are 72.02 % and 46.29 % compared to the 2C-ICE IWP. PD shows an important impact when IWP is larger than 1000 g/m2. At last, two tropical cyclone cases are chosen to test the performance of the networks, the results show a good agreement with the characteristics of the brightness temperature observed by the satellite. The monthly MWHS IWP shows a good consistency compared to the ERA5 and 2C-ICE while it is lower than MODIS IWP.
Complex analysis of the ionosphere variations during the geomagnetic storm at 20 January 2010 performed by Detection of Ionosphere Anomalies (DIA) software and DEMETER satellite data
Authors: Lozbin Anatoliy , Fedun Viktor , Kryakunova Olga
Published: January 2022

Abstract. The Detection of Ionosphere Anomalies (DIA) software was developed and used for ionosphere research in the Institute of Space Technique and Technology of the National Center of Space Research and Technology (Almaty, Republic of Kazakhstan). The software was designed for ionosphere anomalies detection, identification, and analysis from satellite spectral and wave data from scientific payloads installed on the DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) satellite. The main task of DIA software is to provide the researcher with a convenient package for detection and identification of the sources of electromagnetic radiation, variations of the ionic and electronic components of the ionosphere, and other ionosphere parameters from satellite data. Using this software, a complex research of the state of the medium-latitude ionosphere during a geomagnetic storm on 20 January 2010 was done. Electric and magnetic components of the field in ultralow frequency (ULF), extremely low frequency (ELF), and very low frequency (VLF) bands are processed and analyzed, as well as temperature, velocity, and density of ionic and electronic plasma components and fluxes of energetic electrons at satellite altitude during a storm.
Spatially varying relevance of hydrometeorological hazards for vegetation productivity extremes
Authors: Kroll Josephin , Denissen Jasper M. C. , Migliavacca Mirco , Li Wantong , Hildebrandt Anke , Orth Rene
Published: January 2022

Abstract. Vegetation plays a vital role in the Earth system by
sequestering carbon, producing food and oxygen, and providing evaporative
cooling. Vegetation productivity extremes have multi-faceted implications,
for example on crop yields or the atmospheric CO2 concentration. Here, we
focus on productivity extremes as possible impacts of coinciding,
potentially extreme hydrometeorological anomalies. Using monthly global
satellite-based Sun-induced chlorophyll fluorescence data as a proxy for
vegetation productivity from 2007–2015, we show that vegetation
productivity extremes are related to hydrometeorological hazards as
characterized through ERA5-Land reanalysis data in approximately 50 % of
our global study area. For the latter, we are considering sufficiently
vegetated and cloud-free regions, and we refer to hydrometeorological
hazards as water- or energy-related extremes inducing productivity extremes.
The relevance of the different hazard types varies in space;
temperature-related hazards dominate at higher latitudes with cold spells
contributing to productivity minima and heat waves supporting productivity
maxima, while water-related hazards are relevant in the (sub-)tropics with
droughts being associated with productivity minima and wet spells with the
maxima. Alongside single hazards compound events such as joint droughts
and heat waves or joint wet and cold spells also play a role, particularly in dry
and hot regions. Further, we detect regions where energy control transitions
to water control between maxima and minima of vegetation productivity.
Therefore, these areas represent hotspots of land–atmosphere coupling where
vegetation efficiently translates soil moisture dynamics into surface fluxes
such that the land affects near-surface weather. Overall, our results
contribute to pinpointing how potential future changes in temperature and
precipitation could propagate to shifting vegetation productivity extremes
and related ecosystem services.
Exploring the role of bedrock representation on plant transpiration response during dry periods at four forested sites in Europe
Authors: Jiménez-Rodríguez César Dionisio , Sulis Mauro , Schymanski Stanislaus
Published: January 2022

Abstract. Forest transpiration is controlled by the atmospheric water demand, potentially constrained by soil moisture availability, and regulated by plant physiological properties. During summer periods, soil moisture availability at sites with thin soils can be limited, forcing the plants to access moisture stored in the weathered bedrock. Land surface models (LSMs) have considerably evolved in the description of the physical processes related to vegetation water use but the effects of bedrock position and water uptake from fractured bedrock has not received much attention. In this study, the Community Land Model version 5.0 (CLM 5) is implemented at four forested sites with relatively shallow bedrock and located across an environmental gradient in Europe. Three different bedrock configurations (i.e., default, deeper, and fractured) are applied to evaluate if the omission of water uptake from weathered bedrock could explain some model deficiencies with respect to the simulation of seasonal transpiration patterns. Sap flow measurements are used to benchmark the response of these three bedrock configurations. It was found that the simulated transpiration response of the default model configuration is strongly limited by soil moisture availability at sites with extended dry seasons. Under these climate conditions, the implementation of an alternative (i.e., deeper and fractured) bedrock configuration resulted in a better agreement between modeled and measured transpiration. At the site with a continental climate, the default model configuration accurately reproduced the magnitude and temporal patterns of the measured transpiration. The implementation of the alternative bedrock configurations at this site provided more realistic water potentials in plant tissues but negatively affects the modeled transpiration during the summer period. Finally, all three bedrock configurations did not show differences in terms of water potentials, fluxes, and performances on the more northern and colder site exhibiting a transition between oceanic and continental climate. Model performances at this site are low, with a clear overestimation of transpiration compared to sap flow data. The results of this study call for increased efforts into better representing lithological controls on plant water uptake in LSMs.
WIFF1.0: a hybrid machine-learning-based parameterization of wave-induced sea ice floe fracture
Authors: Horvat Christopher , Roach Lettie A.
Published: January 2022

Abstract. Ocean surface waves play an important role in maintaining the marginal ice zone, a heterogenous region occupied by sea ice floes with variable horizontal sizes. The location, width, and evolution of the marginal ice zone are determined by the mutual interaction of ocean waves and floes, as waves propagate into the ice, bend it, and fracture it. In previous work, we developed a one-dimensional “superparameterized” scheme to simulate the interaction between the stochastic ocean surface wave field and sea ice. As this method is computationally expensive and not bitwise reproducible, here we use a pair of neural networks to accelerate this parameterization, delivering an adaptable, computationally inexpensive, reproducible approach for simulating stochastic wave–ice interactions. Implemented in the sea ice model CICE, this accelerated code reproduces global statistics resulting from the full wave fracture code without increasing computational overheads. The combined model, Wave-Induced Floe Fracture (WIFF v1.0), is publicly available and may be incorporated into climate models that seek to represent the effect of waves fracturing sea ice.
An efficient parallel method to compute lithostatic pressure in thermo-mechanical geodynamic models
Authors: Jourdon Anthony , May Dave A.
Published: January 2022

Abstract. Modelling the lithostatic pressure in the Earth's interior is a common problem in Earth sciences. In this study we propose to compute the lithostatic pressure from the conservation of momentum reduced to the hydrostatic particular case. It results a partial differential equation that can be solved using the classical numerical methods. To show the usefulness of solving a PDE to compute the lithostatic pressure we propose two 2D models, one with a deformed mesh and one with a radial gravity acceleration vector and a concentric density distribution. Moreover, we also present a 3D rift model using the lithostatic pressure as a boundary condition. This model shows a high non cylindricity resulting from the Neumann boundary condition that is accomodated by strike-slip shear zones. We compare the result of this numerical model with a simple free-slip boundary conditions model to demonstrate the first order implications of considering "open" boundary conditions in 3D thermo-mechanical models.
Meso- and microplastic distribution and spatial connections to heavy metal contaminations in highly cultivated and urbanised floodplain soilscapes – a case study from the Nidda River (Germany)
Authors: Weber Collin J. , Opp Christian , Prume Julia A. , Koch Martin , Chifflard Peter
Published: January 2022

Abstract. Floodplain soilscapes act as temporary sinks in the environment and are nowadays affected by multiple contaminant accumulations and exposures, including heavy metals and (micro-)plastics. Despite increasing knowledge of the occurrence and behaviour of (micro-)plastics at the interface between aquatic and terrestrial systems, there are still major uncertainties about the spatial distribution of plastics, their sources and deposition, as well as spatial relationships with other contaminants. Our recent case study addresses these questions, using the example of a river system ranging from rural to urban areas. Based on a geospatial sampling approach we obtained data about soil properties, heavy metal contents via ICP-MS analyses, and particle-based (171 µm–52 mm) plastic contents, analysed using sodium chloride density separation, visual fluorescence identification and ATR-FTIR analysis. We found plastic contents of 0.00–35.82 p kg−1 and heavy metal enrichment (Enrichment factor 1.1–5.9). Levels of both contaminations occur in the lower range of known concentrations and show a different spatial distribution along the river course and in the floodplain cross-section. Furthermore, we found that plastic enrichment occurs in the uppermost soil layers, while heavy metal enrichment is located at greater depths, indicating different sources and deposition periods. Finally, direct short to long-term anthropogenic impacts, like floodplain restoration or tillage may affect plastic enrichments, raising questions for future floodplain management.
Prioritisation and Nationalisation of Teaching of Sciences in Ugandan Schools: Practitioners and Documentary Perspectives
Authors: Rukundo Aloysius , Bashaija Athanansio
Published: January 2022

Considerable investment in and prioritisation of teaching of sciences among secondary schools in Uganda have been made. But despite this, performance in sciences remains poor. We sought to understand why this is so, and to this end, the present study explores perceptions regarding reasons surrounding students’ poor performance in sciences. We used an exploratory case study to interview teachers of science, inspectors of schools, and a representative of the Uganda National Examinations Board. Also, documentary analysis was done for a deeper understanding of the study question. Qualitative analysis was employed in the identification of themes and sub-themes. In the findings, what our research suggested is that there is a combination of factors which have resulted in poor science results within schools – the quality of the teaching, the expectations and support of the school and the ability of the pupils themselves, although the quality of teaching seemed to be the major factor. Therefore, this would suggest that the teaching and learning of the sciences in Ugandan schools could benefit from adapting to new ways – teaching the necessary skills, developing the pupils’ scientific interest and skills, and improving facilities within the schools. Further inquiry could be channeled towards understanding apathy in the teaching and learning of sciences, support strategies in resource utilisation, and monitoring of the teaching-learning process.

Published: January 2022

O presente artigo tem como escopo refletir sobre as contribuições da escrita autobiográfica para o processo formativo de futuras pedagogas negras, a partir da análise de escolhas metodológicas da dissertação de mestrado de uma das autoras. Assim, discute-se como o ato de alinhavar o ateliê biográfico de projetos, de Delory-Momberger (2006), ao termo escrevivências de Conceição Evaristo (2006), contribui para formação de professoras negras, tendo como aporte para tal reflexão alguns indícios da referida pesquisa. Nela, estudantes negras do curso de Pedagogia da Universidade Federal Rural do Rio de Janeiro são convocadas a narrarem suas trajetórias formativas através do ato de biografarem-se, subvertendo a ordem, em um processo intrinsecamente formativo. Depreende-se, portanto, que a escolha por tais percursos metodológicos configura-se como também espaço de denúncia, uma vez que se desenvolve no intento de desvelar memórias subterrâneas. No movimento de escrever sobre si, pedagogas negras em construção escrevem sobre memórias ancestrais, por tanto tempo silenciadas, que insurgem, em espaço de pesquisa, através da escrevivência.

Memória e(m) discurso
Authors: Prandi-Gonçalves Maria Beatriz Ribeiro , Sousa Lucília Maria Abrahão
Published: January 2022

A palavra, materializada em músicas, produz efeitos, quer de encantamento quer de estranhamento, nos sujeitos que a ouvem. A partir de condições de produção específicas, a música cumpre, ao longo dos tempos, o papel de transmissão de valores, costumes e hábitos. Assim, ela é comumente utilizada no seio familiar para entretenimento, em atividades pedagógicas, por meio de jogos, dinâmicas, leitura, teatro, entre outros. A pensar nos inúmeros sentidos que se inscrevem nessas canções, este trabalho propõe um gesto de escuta aos dizeres que se materializam em músicas infantis, tendo como suporte teórico-metodológico a Análise do Discurso de linha francesa, fundada por Michel Pêcheux nos anos de 1960 na França. Nessa perspectiva, tomamos o corpus analítico composto por recortes de sequências discursivas de duas canções, para uma melhor compreensão do funcionamento da memória na estabilização de determinados sentidos sobre o sujeito-criança nos dias atuais. Por meio de um olhar crítico, interessa-nos, neste gesto de análise, produzir o questionamento da obviedade desses dizeres sobre a criança, relativamente estáveis no seio social, tendo em vista novas formas de leituras possíveis sobre essa temática.
TEATRO MUSICAL Y PERSPECTIVA DE GÉNERO: LA OBRA SICALÍPTICA DE VICENTE LLEÓ DURANTE SU ETAPA EN EL TEATRO ESLAVA DE MADRID (1907-1912)
Authors: Blasco Magraner José Salvador , Marín-Liébana Pablo , Bueno Camejo Francisco Carlos
Published: January 2022

A principios del siglo XX surgió un nuevo modelo de teatro bufo denominado género sicalíptico caracterizado por sus altas dosis de frivolidad y erotismo que hizo furor en la escena madrileña. Vicente Lleó Balbastre (1870-1922) fue el máximo exponente del género en el teatro musical. Bajo su dirección, como empresario y compositor, el Teatro Eslava se convirtió en el templo de la sicalipsis. En este artículo se estudia el nacimiento y eclosión del género, se recopilan todas las obras sicalípticas de Vicente Lleó en la época dorada de la sicalipsis en el teatro musical y se analizan las principales características de su estilo compositivo.
função da análise na Musica Poetica de J. Burmeister
Authors: Barros Cassiano de Almeida
Published: January 2022

No último capítulo do tratado intitulado Musica Poetica (1606) de Joachim Burmeister, o autor formula a análise musical de um moteto de Orlando di Lasso, com o objetivo de ensinar a compositores iniciantes as possibilidades de estudo do repertório vigente, colocando em evidência os fundamentos do processo criativo musical para torná-los acessíveis para imitação. Essa análise é considerada pela musicologia moderna como uma das primeiras iniciativas do gênero, conforme afirmam Rivera (1993), Palisca (2001), Dunsby e Whittall (1988), por exemplo; e há consenso quanto a seu valor histórico e pedagógico. No entanto, seu valor técnico, ou seja, seu reconhecimento como ilustração das formas de acesso ao repertório antigo é controverso, uma vez que apresenta respostas para perguntas que podem não ter sentido para os analistas e críticos de hoje. De fato, ela foi concebida para atender a demandas de formação musical próprias do início do século XVII e respondem a questões emergentes desse contexto. Considerando que o distanciamento histórico entre nosso tempo presente e seu passado de origem é também um distanciamento cultural, reconheço que o estudo dessa análise em seus próprios termos nos possibilita recuperar conceitos, ideias, técnicas, processos, procedimentos e modos de escuta e reflexão ocultos por esse distanciamento, superando anacronismos e contribuindo para a renovação de sua compreensão hoje.

Estudio del sistema compositivo de Luis Bedmar Encinas
Authors: Manchado López Andrés Carlos
Published: January 2022

Este trabajo es un estudio de la vida profesional de Luis Bedmar Encinas, compositor, director de orquesta y pedagogo musical, a través de una óptica antropológico-musicológica, prestando atención a los diferentes planos en los que se desenvuelve su actividad compositiva: lo popular y lo culto, lo clásico y lo contemporáneo. A través del estudio de la Suite Poliserial para Órgano se analizará su método compositivo y se mostraran las características más relevantes de su música, señalando lo más destacado de su producción musical, grande en calidad y cantidad. Luis Bedmar es un músico que ha cultivado el estudio y profundizado en la investigación etnomusicológica del folclore andaluz llegando a captar su esencia y consiguiendo por un lado llegar a una abstracción  perfecta y eidética de lo andaluz y por otro adaptarse a cada una de las vertientes estilísticas en las que trabaja: consecuencia de ello son el desarrollo de un sistema compositivo propio y el conseguimiento de una estética propia – fruto de la unión de esa raíz popular con los principios estructuralistas utilizados por Schoenberg – que se interna en la expresión de un andalucismo musical profundo y no cae en los tópicos tradicionales ni en imitaciones de lo ya realizado. La metodología empleada es mixta habiendo sido necesario combinar la análisis documental de fuentes impresas variadas con el método de la entrevista según la historiografía oral actual.
Birdsongs, Structure and Harmonic colour of Non-birdsong Subjects in Olivier Messiaen’s ‘La bouscarle’ from Catalogue d’oiseaux
Authors: Loo Fung Chiat , Loo Fung Ying
Published: January 2022

This paper analyses ‘La bouscarle’, a movement from Catalogue d’oiseaux, which is one of the most extensive piano works written by Oliver Messiaen. A distinctive characteristic of this comparatively short movement is the harmonic colour constructed from the composer’s mode 3 in the representation of the river theme, serving as an important subject that provides the flow and structure for the entire work. Mode 3, which forms an A major tonality for the river theme and the portrayal of the kingfisher’s colour, also provides a less dissonant harmony that is different from the harmonies used for habitats presented in other movements of the Catalogue. The soloist, the Cetti’s warbler, with its brief and brusque call, produces a contrasting mood with the lyrical chordal river theme. The majority of birdsongs in this work shares similar characteristics with the soloist’s, except the more melodically delicate blackbird, robin, and blackcap, with their call matching the river theme. It is thus concluded that birdsongs in this movement can also be found and feature their characteristics similarly in other Messiaen’s works.
música-teatro brasileira como projeto de modernização: algumas reflexões a partir de obras de Jocy de Oliveira e Gilberto Mendes
Authors: De Oliveira Magre Fernando , Garcia Denise
Published: January 2022

Este trabalho busca identificar elementos característicos da música-teatro brasileira e compreender de que maneira ela responde às expectativas de um país em processo de criação de sua identidade. Partimos do pressuposto de que a música-teatro brasileira surge por meios e razões diferentes de sua correspondente europeia e que isso se dá em um contexto sociocultural muito diverso. Para entender tal contexto, recorremos à reflexão conduzida por Canclini (1990) sobre a ideia equivocada de que o modernismo artístico deveria ser reflexo da modernização social, trazendo o debate para o contexto latino-americano, chegando à noção de hibridação. Para observar como o processo de modernização afeta a música-teatro, analisamos obras de Jocy de Oliveira e Gilberto Mendes, refletindo sobre seus modos de criação e recepção.
Quando o músico e o educador se encontram
Authors: Nassif Silvia Cordeiro
Published: January 2022

Este artigo apresenta uma pesquisa em um curso de Licenciatura em Música sobre as trajetórias curriculares dos graduandos em relação com suas experiências musicais anteriores. Tendo como abordagem teórico-metodológica o materialismo dialético, sobretudo as contribuições da teoria histórico-cultural de Vigotski e colaboradores e a filosofia da cultura do Círculo de Bakhtin, busca, através de questionários e entrevistas, a perspectiva dos próprios estudantes sobre as questões em foco. O recorte aqui apresentado examina a diversidade de perfis do corpo discente, suas identidades como músicos e potencialidades como educadores. A principal conclusão extraída da análise leva à necessidade de superação de uma série de dicotomias sobre as quais a estrutura curricular se assenta, entre elas a oposição músico/educador.
El músico argentino Adolfo Reisin y las estéticas de la improvisación colectiva
Authors: Moro Vallina Daniel
Published: January 2022

El presente artículo plantea una aproximación a la figura del músico argentino Adolfo Reisin (1936-2020), aún desconocido para el gran público y la comunidad musicológica. Se profundiza en primer lugar en el trabajo de Reisin para el medio teatral en la Argentina de los años 60, donde formó parte del Teatro de los Independientes. A continuación, se analizan las principales influencias internacionales que configuraron su estética (Pierre Schaeffer, Luigi Nono e Iannis Xenakis, entre otros) y cómo evolucionó hacia la práctica de la libre improvisación colectiva. La principal contribución de Reisin en este campo fue el llamado “solfeo corporal-gestual”, que explicamos combinando el análisis de fuentes de archivo, videograbaciones y entrevistas personales al autor.

O ditado melódico é um exercício frequente na disciplina de Percepção Musical. Ele vem sendo discutido, criticado, ressignificado e recontextualizado pela literatura há algumas décadas, mas sabe-se que práticas ligadas a ele ainda podem estar vinculadas ao tradicionalismo. Este estudo buscou investigar quais têm sido as estratégias para realização de ditados melódicos mais empregadas no Brasil, e observar a quais resultados elas têm levado seus usuários. Por meio de uma survey realizada com 236 estudantes, profissionais e amadores em música, das cinco regiões do Brasil, observou-se a prevalência de práticas criticadas, mas também que os participantes com melhor desempenho utilizam estratégias defendidas pelos teóricos.
Transhumanismo como religião?
Authors: Vilaça Murilo Mariano , Leite Araujo Luiz Bernardo
Published: January 2022

Resumo: neste artigo, examinamos a ideia de que o transumanismo é uma religião. Para isso, partimos de uma definição prototípica do transumanismo, que orientará nossa abordagem. Na sequência, apresentamos a ideia de transumanismo como um tipo de religião. Além de destacar as semelhanças entre transumanismo e religião apontadas pelos defensores de tal possibilidade de associação/identificação, apresentamos algumas das suas alegações fundamentais, concluindo a seção com uma lista de diferenças entre transumanismo e religião (mais especificamente, a cristã). Em seguida, tendo em mente semelhanças e diferenças, analisamos as alegações apresentadas na seção anterior, o que nos leva à contestação da plausibilidade daquela ideia. Concluímos o artigo com uma breve reconstrução da teoria habermasiana da religião, a fim de fundamentar a manutenção da separação entre as esferas da ciência (saber) e da religião (fé), o que seria fundamental para salvaguardar o horizonte epistêmico e normativo das sociedades pós-metafísicas, democráticas e pluralistas.
Cuniculus paca Linnaeus, 1766 (Cuniculidae, Rodentia) no Holoceno da Gruta Cuvieri, Brasil
Authors: Chahud Artur
Published: January 2022

A região de Lagoa Santa é conhecida pelo importante complexo de cavernas, sendo que em muitas delas encontra-se material osteológico de fauna extinta e atual. A Gruta Cuvieri faz parte deste importante complexo cárstico e possui grande quantidade de restos de roedores do Quaternário, sendo que a família Cuniculidae é a que apresentou os maiores espécimes. O presente estudo comenta os restos de Cuniculus paca de idade holocênica da Gruta Cuvieri. Os restos são do Holoceno Médio e Final e incluem três indivíduos adultos desarticulados e incompletos. O aparecimento desta espécie ocorre simultaneamente com o aumento de umidade na região de Lagoa Santa. Ocorrências dessa espécie em sítios arqueológicos e paleontológicos de idade holocênica são comuns, mas pouco divulgadas, e a publicação dessas ocorrências poderá contribuir futuramente para estudos evolutivos de Cuniculidae no território brasileiro.

Published: January 2022

In this new era, warfare techniques have changed as demand for the new modern world. This is an economic, political, and social connectivityoriented century where the media is the crucial instrument of hybrid warfare. The mindset, narrative, perception, and information are the primary weapons of hybrid war or media warfare. This war can destroy a country’s culture from the inside and disturb people’s beliefs and views; moreover, it can also impact a country’s economy with high intensity. People are expected to go rogue and become rebels against their state or nation. Usually, the reasons for this war are frustration, lack of authentic reason, and or absence of political objective or ideology to serve the country. This war has a huge impact on people’s minds and thinking for a long time. It separates people into groups and segments believing in different propaganda and fallacy. The research is a qualitative analysis of previously published relevant documents. The study concludes that media has played an immense role in building or shaping a narrative that one wants since media is among the powerful weapons used to converge or diverge people’s minds against one idea.

In 2020 and 2021, the Covid-19 pandemic caused drastic consequences around the world. The disease causes a flu syndrome with clinical pictures ranging from mild to severe. Since it is a systemic flu syndrome, several clinical manifestations have been described for this disease, but cases of hiccups associated with Covid-19 have rarely been reported. This report describes a rare case presented in which a patient with Covid-19 developed respiratory discomfort after complaining of persistent hiccups.  The patient was treated clinically and experienced a sudden improvement in their dyspnoea immediately after the disappearance of the hiccups crisis.  This sudden improvement suggests a very likely cause–effect relationship.

Published: January 2022

A nonexistence result is proved of the space higher-order nonlinear Schrodinger equation where m > 1, n > 1 and p > n. Our method of proof rests on a judicious choice of the test function in the weak formulation of the equation. Then, we obtain an upper bound of the life span of solutions. Furthermore, the necessary conditions for the existence of local or global solutions are provided.Next, we extend our results to the 2 × 2 – system.
Adapting the University Ethical Climate, a Necessity in the Pandemic Context
Authors: DRĂGHICI Teodora , ILIE Oana-Antonia
Published: January 2022

This paper aims to analyze the consequences of the pandemic crisis measures on the educational system, in terms of the university ethical climate, trying to provide solutions for creating and maintaining an optimal climate for learning and character development. The ethical organizational climate is at the core of the ethical decision-making, ethical behavior, and development in the university environment. The university ethical climate reflects the collective moral behaviors, facilitates commitment, respect for ethical norms and integrity of the parties involved in the educational process, leading to the development of an ethical culture of responsibility. In the context of the current pandemic, the educational solutions adopted, although effective in the short term, in the long run can impinge on the basic values the traditional school is built on. An open-door policy is needed more than ever in order to adapt to the new reality generated by the crisis, to keep universities in an area of moral authority, to avoid moral obscurantism and absenteeism, consequences of the evading the responsibility tendency, generated by the online school.

A 43-years-old woman was hospitalized with headaches progressing over the 10 preceding days and an epileptic seizure. The patient had a Marfan disease which required two cardiac surgeries - the last one in 2014 with the installation of an aortic tube and a mechanical aortic valve. A gadolinium-enhanced magnetic resonance image of the brain was performed and revealed numerous lesions, some with ring enhancement, substantial edema but without mass effect (Figure 1). Additional tests were carried out including blood cultures, transthoracic and trans-oesphageal echocardiogram, Coxiella burnetii, Bartonella spp. and Mycoplasma pneumonia serologies that remained all negative. After 48 h incubation of CT-guided brain abscess aspiration, small yellow colonies appear on chocolate blood agar and Gram staining shows small Gram-negative bacilli (Figures 2,3). Identification realized by MALDI-TOF mass spectrometry revealed Aggregatibacter aphrophilus. Blood cultures remained sterile.

We describe 8 patients with confirmed Covid-19 infection requiring high flow oxygen and respiratory support for adult Respiratory distress syndrome (ARDS) for a mean duration of 12 days. These patients had already received standard treatments for Covid-19, including broad spectrum antibiotics, dexamethasone, heparin and remdesivir along with entry to the recovery trial according to patient choice. Due to on-going high oxygen demands and respiratory support, these patients were at increasing risk of significant lung injury and the development of fibrotic lung changes. Intravenous low dose methylprednisolone was therefore given in an attempt to assist resolution of the ARDS. The low dose was chosen to reduce the cytokine storm and minimise the risk of a super-infection. This led to improvement in 6 out of 8 patients allowing oxygen weaning (mean duration 4.5 days) and discharge home within a mean duration of 11 days. Five patients were discharge home with low flow oxygen (mean 2.8 L/min) with community based weaning. The 2 non-responders subsequently deteriorated further and were managed palliatively. We describe the cases and discuss the current literature with regard to the use of methylprednisolone in Covid-19 ARDS. Keywords: ARDS; Covid 19; methylprednisolone; respiratory failure; fibrotic lung injury.

Background: The role of lipids and inflammation in the patients with cardiovascular complications has been reported. The primary aim of the current randomized controlled double-blind clinical trial was to compare the influence of Atorvastatin and Rosuvastatin on the lipid profile and inflammatory markers in the patients with Acute Coronary Syndrome (ACS). Methods: This study included 84 cases with approved diagnosis of ACS. Patients were randomized into two groups (42 cases each) and received Atorvastatin (80 mg/day) or Rosuvastatin (40 mg/day) for two months. After this period, levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, C-reactive protein (CRP), and monocyte chemoattractant protein-1 (MCP-1) and lipid profile was determined in serum samples using enzyme-linked immunosorbent assay (ELISA). Results: It was observed that there was a significant reduction in the TNF-α (P= 0.008) and MCP-1 (P= 0.001) levels in the Atorvastatin group. Moreover, there was a significant decrease in the TNF-α (P= 0.001) and MCP-1 (P= 0.003) levels in the Rosuvastatin group. Atorvastatin caused statistically significant decreased levels of LDL (P= 0.014), TG (P= 0.012), and total cholesterol (P= 0.011). As such, Rosuvastatin also caused statistically significant reduced levels of LDL (P= 0.028), TG (P= 0.010), and total cholesterol (P= 0.003). No differences were observed in the levels of inflammatory markers and lipid factors between patients receiving Atorvastatin comparted to Rosuvastatin. Conclusions: Although both Atorvastatin and Rosuvastatin seem to beneficial in soothing inflammation and decreasing the levels of lipids in ACS patients, none of them privilege the other one within this context. Keywords: acute coronary syndrome; atorvastatin; rosuvastatin; inflammation; lipid profile.
