The UKSCAPE-G2G river flow and soil moisture datasets: Grid-to-Grid model estimates for the UK for historical and potential future climates
Authors: Kay Alison L. , Bell Victoria A. , Davies Helen N. , Lane Rosanna A. , Rudd Alison C.
Published: January 2023

Abstract. Appropriate adaptation planning is contingent upon information about the potential future impacts of climate change, and hydrological impact assessments are of particular importance. The UKSCAPE-G2G datasets were produced, as part of the NERC UK-SCAPE programme, to contribute to this information requirement. They use the Grid-to-Grid (G2G) national-scale hydrological model configured for both Great Britain and Northern Ireland (and the parts of the Republic of Ireland that drain to rivers in NI). Six separate datasets are provided, for two sets of driving data — one observation-based (1980–2011) and one climate projection-based (1980–2080) — for both river flows and soil moisture on 1 km x 1 km grids across GB and NI. The river flow datasets include grids of monthly mean flow, annual maxima of daily mean flow, and annual minima of 7-day mean flow (m3s-1). The soil moisture datasets are grids of monthly mean soil moisture content (m water / m soil), which should be interpreted as depth-integrated values for the whole soil column. The climate projection-based datasets are produced using data from the 12-member 12km regional climate model ensemble of the latest UK climate projections (UKCP18), which uses RCP8.5 emissions. The production of the datasets is described, along with details of the file format, and how the data should be used. Example maps are provided, as well as simple UK-wide analyses of the various outputs. These suggest potential future decreases in summer flows, annual minimum 7-day flows, and summer/autumn soil moisture, along with possible future increases in winter flows and annual maximum flows. References are given for published papers providing more detailed spatial analyses, and some further potential uses of the data are suggested.

Published: January 2023

Abstract. In the last century an increasing number of extreme weather events have been experienced across the globe. These events have also been linked to changes in water quality especially due to heavy rains, flooding, or droughts. In terms of blue economic activities, one major threat are harmful algal bloom events that tend to be widespread and can last up to several days. We present and discuss advanced measurements of a bloom involving the cyanobacterium Nodularia spumigena conducted by hyperspectral optical technologies through experiments-of-opportunity. Absorption coefficients, absorbance and fluorescence were measured in the laboratory and these are available via (https://doi.org/10.4121/21610995.v1 (Wollschläger et al., 2022), https://doi.org/10.4121/21822051.v1 (Miranda et al., 2023) and https://doi.org/10.4121/21904632.v1 (Miranda and Garaba, 2023). Data used to derive the above-water reflectance is available via https://doi.org/10.4121/21814977.v1 (Garaba, 2023) and https://doi.org/10.4121/21814773.v1 (Garaba and Albinus, 2023). Additionally, hyperspectral fluorescence measurements of the dissolved compounds in the water were done. The hyperspectral measurements were conducted over a wide spectrum (200–2500 nm). Identification of the cyanobacterium was completed by visual analyses under a microscope. Diagnostic optical features were determined using robust statistical techniques. Water clarity was inferred from Secchi disk measurements https://doi.org/10.1594/PANGAEA.951239 (Garaba and Albinus, 2022). Full sequences were obtained of the 16S rRNA and rbcL genes revealing a very strong match to Nodularia spumigena, data available via GenBank https://www.ncbi.nlm.nih.gov/nuccore/OP918142/ (Garaba and Bonthond, 2022b) and https://www.ncbi.nlm.nih.gov/nuccore/OP925098 (Garaba and Bonthond, 2022a). The chlorophyll-a and phycocyanin levels determined are in open-access https://doi.org/10.4121/21792665.v1 (Rohde et al., 2023). Our experiments-of-opportunity echo the importance of sustainable, simplified, coordinated and continuous water quality monitoring as a way to thrive for the targets 2 set in the United Nations Sustainable Goals (e.g., Goals 6, 11, 12 and 14) or European Union Framework Directives (e.g. Water, Marine Strategy).
Randomized Block Nonparametric Temporal Disaggregation of Hydrological Variables RB-NPD (version1.0) – model development
Authors: Lee Taesam , Ouarda Taha B. M. J.
Published: January 2023

Abstract. Stochastically simulated data have been employed for hydrological variables in critical water-related risk management. The simulated data can be utilized to assess the existing flood protection structure and future mitigation frameworks. Disaggregation of the simulated annual data to a lower time scale is often required since water resource management and flood mitigation plans should be done in a fine scale such as a monthly or quarter-monthly. In the current study, the randomized random block length was proposed for the nonparametric disaggregation model since one of the major weakness points for the nonparametric disaggregation model is repetition of similar patterns in the disaggregated data. Furthermore, long-term dependence structure was also mainly focused to preserve since consistent high-flow results devastating damages to inundated area. The proposed model was compared with the existing parametric and nonparametric disaggregation models. The annual net basin supplies (NBS) of the Lake Champlain–Richelieu River (LCRR) Basin was employed to test the performance of the proposed model by reproducing the critical statistics of the 2011 flood in the LCRR Basin. The 2011 flood occurred and was sustained for a few months. The results show that the existing parametric and nonparametric models have limitations and shortcoming and do not provide sufficient temporal dependence. In contrast, the proposed random block-based nonparametric disaggregation (RB-NPD) model with further model enhancement by the genetic algorithm mixture illustrates that the proposed RB-NPD model can be a comparable alternative and that its enhancement is suitable for disaggregating the annual NBS data for the LCRR Basin.

Published: January 2023

Abstract. The US Northern Great Plains and the Canadian Prairies are known as the world’s breadbaskets for its large spring wheat production and exports to the world. It is essential to accurately represent spring wheat growing dynamics and final yield and improve our ability to predict food production under climate change. This study attempts to incorporate spring wheat growth dynamics into the Noah-MP crop model, for a long time period (13-year) and fine spatial scale (4-km). The study focuses on three aspects: (1) developing and calibrating the spring wheat model at point-scale, (2) applying a dynamic planting/harvest date to facilitate large-scale simulations, and (3) applying a temperature stress function to assess crop responses to heat stress amid extreme heat. Model results are evaluated using field observations, satellite leaf area index (LAI), and census data from Statistics Canada and the US Department of Agriculture (USDA). Results suggest that incorporating a dynamic planting/harvest threshold can better constrain the growing season, especially the peak timing and magnitude of wheat LAI, as well as obtain realistic yield compared to prescribing a static province/state-level map. Results also demonstrate an evident control of heat stress upon wheat yield in three Canadian Prairies Provinces, which are reasonably captured in the new temperature stress function. This study has important implications for estimating crop production, simulating the land-atmosphere interactions in croplands, and crop growth’s responses to the raising temperatures amid climate change.
Impact of icebergs on the seasonal submarine melt of Sermeq Kujalleq
Authors: Kajanto Karita , Straneo Fiammetta , Nisancioglu Kerim
Published: January 2023

Abstract. The role of icebergs in narrow fjords hosting marine-terminating glaciers in Greenland is poorly understood, even though iceberg melt results in a
substantial freshwater flux that can exceed the subglacial discharge. Furthermore, the melting of deep-keeled icebergs modifies the vertical
stratification of the fjord and, as such, can impact ice–ocean exchanges at the glacier front. We model an idealised representation of the
high-silled Ilulissat Icefjord in West Greenland with the MITgcm ocean circulation model, using the IceBerg package to study the effect of submarine
iceberg melt on fjord water properties over a runoff season, and compare our results with available observations from 2014. We find the subglacial
discharge plume to be the primary driver of the seasonality of circulation, glacier melt and iceberg melt. Furthermore, we find that melting of
icebergs modifies the fjord in three main ways: first, icebergs cool and freshen the water column over their vertical extent; second, iceberg-melt-induced changes to fjord stratification cause the neutral buoyancy depth of the plume and the export of glacially modified waters to be deeper;
third, icebergs modify the deep basin, below their vertical extent, by driving mixing of the glacially modified waters with the deep-basin waters
and by modifying the incoming ambient waters. Through the combination of cooling and causing the subglacial-discharge-driven plume to equilibrate
deeper, icebergs suppress glacier melting in the upper layer, resulting in undercutting of the glacier front. Finally, we postulate that the impact
of submarine iceberg melt on the neutral buoyancy depth of the plume is a key mechanism linking the presence of an iceberg mélange with the
glacier front, without needing to invoke mechanical effects.
Increasing The Competence Of Teachers In Improving The Ability Of Creative Thinking And Action Of Students Through The Utilization Of Animation Learning Videos
Authors: Kristina Elsa
Published: January 2023

This research is motivated by the weakness of teachers in the application of ICT in the learning process in the classroom. This is based on observations in the teacher's lesson plan that never includes ICT-based learning media. The purpose of this study was to determine the increase in teacher competence in applying ICT in the learning process through in-house training. In-house training was chosen as an effort to increase teacher competence because in terms of time it does not interfere with the main task of teachers and in terms of costs it does not require a lot of money, because it is carried out internally in schools. The method used is school action research (PTS) with two cycles, each cycle consisting of planning, implementing corrective actions, observing and reflecting. The results of the study showed that there was an increase in teacher competence in implementing ICT through in-house training for teachers at SDN 3 Sukamenak, Purbaratu District, Tasikmalaya City. Assessment through the in-house training observation rubric in cycle 1 was only 30% ready to take part in the activity, so it was included in the poor category, and the results of the assessment in the second cycle which reached a value of 80%, were in the very good category. While the teacher's activity in the implementation of learning in the second cycle is better than in the first cycle. Where the final result is an increase in teacher competence in applying ICT in the learning process with a 40% increase in the percentage.

Published: January 2023

The moral and mental degradation of students indicates low emotional intelligence in various countries, including Indonesia, with indicators of loss of manners, bad language, bullying, brawling, etc. This study aimed to determine the influence of students’ emotional intelligence levels on the manners character of 5th-grade students of Madrasah Ibtidaiyah al-Islam Balesari, Magelang, Indonesia. The study used a quantitative approach with a quasi-experimental method and a nonequivalent control group design. Sampling was done by a random sampling technique with a purposive sampling type. Data were collected through observation, questionnaires, and documentation with simple linear regression analysis assisted by SPSS 16 software for Windows. The results show that the average value of emotional intelligence in the experimental class is 79.4% (high-level category), while the control class is 72% (medium-level). On the other hand, the character of manners in the experimental class is 79% (very good category), and in the control class is 72% (sufficient category). The results indicate that there is an influence of students’ emotional intelligence on their manners and characters. The results of a simple regression test in the experimental class are Y = 11.354.–0.861 with a significant value of 0.00. The significance value is <0.05 (0.00<0.05), then Ha is accepted and Ho is rejected. The results of a simple regression test in the control class are Y = 17,323- 0.760 with a significant value of 0.00, the significance value <0.05 (0.00 <0.05), then Ha is accepted and Ho is rejected. The research findings concluded that the higher the level of emotional intelligence, the higher the manners of character, and vice versa. Further research needs to be conducted to explore the influence of emotional intelligence on the students’ character as a whole
ON THE BENCH-CAPON VALUE-BASED ARGUMENTATION FRAMEWORK
Authors: Фролов Константин Геннадьевич
Published: January 2023

В статье рассматриваются выразительные возможности модели Бенч-Капона для структуры аргументации, основанной на ценностях. Основным отличием этой модели от классического подхода Дунга является то обстоятельство, что, помимо отношения атаки, определённого на упорядоченных парах аргументов, в этой модели выделяется особый подкласс данного отношения - отношение отмены, то есть успешной атаки с точки зрения определённой аудитории с учетом её ценностных приоритетов. Эта особенность расширяет выразительные возможности данной модели, а также позволяет иметь единственное непустое предпочтительное расширение для данной аудитории для всякой абстрактной структуры аргументации, в которой отсутствуют циклы, состоящие из аргументов, поддерживающих одну и ту же ценность.

In this paper I examine the expressive power of the Bench-Capon value-based argumentation framework. In frameworks of this type we have two types of relations between arguments: the attack relation and the defeat relation, which is a class of successful attacks from the point of view of a certain audience, taking into account its value priorities. The main advantage of this approach is that every audience-specific value-based argumentation framework with no single-valued cycles has a unique, nonempty preferred extension.

NON-CONCEPTUAL CONTENT OF EXPERIENCE AND COGNITIVE PERCEPTUAL PENETRATION
Authors: Пономарёв Андрей Игоревич
Published: January 2023

Проблема содержания ментальных состояний привлекает много внимания современных исследователей восприятия. Содержание переживаний носит неконцептуальный характер, в то время как содержание когнитивных состояний - концептуальный. Когнитивное проникновение в восприятие даёт основания для скептицизма, поскольку только независимые перцептивные переживания могут быть основанием для убеждений. В рамках подхода А. Рафтопулоса показано, что раннее зрение непроницаемо для когнитивных состояний, что позволяет преодолеть скептицизм. Однако этот подход не лишён недостатков, главным из которых оказывается акцент на зрительном восприятии.

The problem of the content of mental states attracts much attention in the contemporary philosophy of perception. The content of perceptual experience is non-conceptual, whereas content of cognitive states is conceptual. Cognitive perceptual penetration gives a reason to skepticism because only independent perceptual experiences can be grounds for believes. Within the approach professed by Athanassios Raftopoulos, it is shown that early vision is impenetrable for cognitive states, which could be a promising answer to skepticism. However, this approach is not free from weaknesses, of which the principal one is its focus on visual perception.

We show that these two families which differ by their winding arrangements have very different resonant mechanisms and we provide effective models which are derived thanks to asymptotic analysis.
A Homogenization of Irrational Metamaterials
Authors: Guenneau Sébastien
Published: January 2023

Following the advent of electromagnetic metamaterials, researchers working in wave physics have translated concepts of engineered media to elastodynamics using analogies between Maxwell and Navier equations. Seismic metamaterials have emerged for soft soils structured at the meter scale, and have been tested ten years ago with full-scale experiments on holey soils to achieve shielding [1] and lensing [2] effects. Born in the soil, seismic metamaterials have emerged from the field of tuned-resonators buried in the soil, around building's foundations or near the soil-structure interface as local seismic isolators. Their designs are inspired e.g. by small scale mechanical metamaterials with a negative Poisson ratio, known as auxetic metamaterials [3]. Forests of trees have been interpreted as above-surface resonators, and coined natural seismic metamaterials [4]. Forest of trees not only have an effect on Rayleigh waves [4], but also on Love waves, that can be viewed as a counterpart of spoof plasmons in electromagnetics [5]. On the other hand, it is possible to control surface and volume seismic waves by structuring soft soils with columns of concrete clamped to the bedrock [6]. In this talk we will envision future developments of large scale auxetic metamaterials for building's foundations [3], above and below surface resonators for seismic protection [4, 5, 6] as well as metamaterial-like transformed urbanism at the city scale [7].
Active exterior cloaking for the heat equation
Authors: Vasquez Fernando Guevara
Published: January 2023

We present a method for cloaking objects from thermal measurements that uses active sources instead of exotic materials and where the sources do not completely surround the object to cloak. Rather than working with the heat equation in the time domain as in [3], our method relies on the frequency domain formulation as Helmholtz equation solutions with complex wavenumbers. This extends the active exterior cloaking for the Helmholtz equation method in [2] from positive wavenumbers to complex ones. In addition, we give convergence estimates for this cloaking approach[4]. We believe the same approach applies to cloaking in dispersive media.

Plasmon metasurfaces for detection of SARS-CoV-2 Spike Glycoprotein Using Surface-Enhanced Raman Scattering
Authors: Sarychev Andrey
Published: January 2023

We present SERS-active metal-dielectric metasurfaces fabricated from metal periodic nanograting deposited on a dielectric substrate. The metasurface consists of a modulated dielectric, which is covered by a thin silver layer. The metasurface operates as an open plasmon resonator. The theory of plasmons excited in the open resonator formed by a metal nanograting is developed. Label-free SERS recording of the receptor-binding domain of SARS-CoV-2 S-glycoprotein is proposed, which allows sensing characteristic protein Raman spectra at the concentrations sufficient for the ultrasensitive detection of viral protein antigens.
Breakdown of light transport models in photonic scattering slabs with strong absorption and anisotropy
Authors: Akdemir Ozan
Published: January 2023

The radiative transfer equation (RTE) models the transport of light inside photonic scattering samples such as paint, foam and tissue. Analytic approximations to solve the RTE fail for samples with strong absorption and dominant anisotropic scattering and predict unphysical negative energy densities and the diffuse flux in the wrong direction. Here we fully characterize the unphysical regions of three popular approximations to the RTE for a slab, namely the P1 approximation (or diffusion approximation), the P3 approximation, and a popular modification to P3 that corrects the forward scattering in the approximation. We find that the delta function correction to P3 eliminates the unphysical range in the forward scattering. In addition, we compare the predictions of these analytical methods to exact Monte Carlo simulations for the physical and unphysical regions. We present maps of relative errors for the albedo and the anisotropy of the scatterers for a realistic index contrast typical of a polymer slab in air and optical thickness.
Topological corner modes in the two-dimensional Su-Schrieffer-Heeger model and their robustness against disorder
Authors: Coutant Antonin
Published: January 2023

This work studies a two-dimensional extension of the Su-Schrieffer-Heeger model on a square lattice. This model has been shown to be a higher order topological insulator, displaying not only edge modes but also corner modes. This work analyzes their main properties, and in particular, their robustness to the presence of disorder. Precise conditions for the existence of zero energy corner modes in the presence of disorder is obtained. Moreover, it is shown how this model can be exactly realised in acoustics using networks of waveguides.
Exotic Wave Phenomena in Time Metamaterials
Authors: Alu Andrea
Published: January 2023

In this talk, I will discuss our group recent progress in exploring the exotic wave-matter interactions occurring at time interfaces, emerging when the material properties are abruptly switched in time, and in time metamaterials formed by suitable combinations of time interfaces. We discuss general energy considerations in the involved temporal scattering processes, with special emphasis on situations in which multiple waves are present in the materials, and the involved materials are non-Hermitian and/or nonlocal. We also discuss more complex scenarios in which the temporal switching is not abrupt, and the case of open resonators switched in time, enabling efficient phase conjugation and frequency conversion of the scattered fields.
Near-field characterization of surface plasmon polaritons on single-crystalline gold platelets
Authors: Casses Laura
Published: January 2023

The subwavelength confinement of surface plasmon polaritons (SPPs) makes them useful for various applications such as nanoplasmonic circuits, light generation and solar energy conversion. Scattering-type scanning near-field optical microscopes (s-SNOM) allow the direct measurement of the SPPs. However, in a reflection configuration, their full quantitative characterization is challenging because of complex wave patterns resulting from the interference between several excitation pathways. In a previous study, it has been shown that the wavelength of the SPPs launched by a s-SNOM tip (called tip-launched SPPs) could be retrieved by analyzing the s-SNOM signal far from the edges of the platelets [1]. In this study, we present results from the interferometric near-field measurements of both the amplitude and phase of SPPs on large single-crystalline gold platelets in the visible spectral range [2]. We study systematically the influence of the angle of the incident light on the SPPs. We find that the signal of the tip launched SPPs is best disentangled from other signals at grazing incident angle relative to the platelet’s edge. Moreover, we introduce a simple theoretical model to explain the π/2 phase shift observed between the SPP amplitude and phase profiles. Using this model, the wavelength Λtl and propagation length Ltlp of the tip-launched SPPs are retrieved by isolating and fitting their signals far from the edges. Our experimental results are in excellent agreement with our model using gold refractive index values from the literature. The presented method to fully characterize the SPP complex wavevector could enable the quantitative analysis of polaritons occurring in different materials in the visible range.
The condensed matter physics of MRI
Authors: Novikov Dmitry
Published: January 2023

Diffusion of water molecules, ubiquitous in all living organisms, serves as a bridge between the mesoscopic condensed matter physics and biomedical imaging. By measuring water diffusion propagator at a micrometer scale with NMR-based methods, magnetic resonance imaging (MRI) becomes sensitive to the cellular-level tissue architecture, and its physiological and pathological changes. Hence, the images produced by MRI scanners can reveal a wealth of information at the scale orders of magnitude below their nominal resolution. Applying the methods developed to describe transport in disordered systems thereby helps quantify human tissue microstructure in vivo and diagnose diseases.
Universal Algebraic Logic - Dedicated to the Unity of Science
Authors: Gyenis Zalán
Published: January 2023

This is the presentation of a book that gives a comprehensive introduction to Universal Algebraic Logic. The three main themes are (i) universal logic and the question of what logic is, (ii) duality theories between the world of logics and the world of algebra, and (iii) Tarskian algebraic logic proper including algebras of relations of various ranks, cylindric algebras, relation algebras, polyadic algebras and other kinds of algebras of logic. One of the strengths of our approach is that it is directly applicable to a wide range of logics including not only propositional logics but also e.g. classical first order logic and other quantifier logics. Following the Tarskian tradition, besides the connections between logic and algebra, related logical connections with geometry and eventually spacetime geometry leading up to relativity are also part of the perspective of the book. Besides Tarskian algebraizations of logics, category theoretical perspectives are also touched upon.
Controlling the angular memory effect through diffusive media
Authors: Yilmaz Hasan
Published: January 2023

The angular memory effect led to a paradigm shift in imaging through diffusive media by harnessing the spatial information from the multiply scattered or diffused light. However, it has certain constraints such as finite angular correlation range and predetermined direction that correlations are observed. Here, we propose and experimentally demonstrate a general approach to arbitrarily control the angular memory effect in diffusive media. Introducing an angular memory operator by applying a certain transformation to the field transmission matrix, we show that the eigenvectors of such an operator have perfect “memory” for arbitrarily chosen angles and tilt directions of input and output wavefronts. Our work paves the way to customize the memory effect of both classical and quantum waves for imaging, metrology, and communication applications in complex scattering systems.
Speckle statistics in space and time-disordered media

This includes focussing and redirecting wave energy. To further illustrate the control that it is possible to have over elastic waves and vibration an elastic orbital angular momentum device will be discussed that converts one wave mode into another.
A landscape method to unveil high-frequency localized modes in random acoustic metamaterials
Authors: Cottereau Régis
Published: January 2023

Mechanical media with randomly fluctuating parameters are fundamentally different from periodic (or homogeneous) media in that, above a certain threshold (and depending on dimensionality), eigenmodes are localized. While that feature may be extremely useful in practice, for any application involving vibration isolation, numerical methods currently lack for the prediction of these localized eigenmodes at a reasonable cost. Recently, the so-called localization landscape method was proposed [1] to predict such localized modes in quantum systems (Schrödinger equation). It allows to predict the locus of all the lowest localized eigenmodes by solving one single (cheap) elliptic problem. Although very elegant, this method is not useful for classical (acoustic) equations because the lower eigenmodes for this equation are de-localized and essentially hide the higher modes, which are of interest. The talk will discuss and compare the operators corresponding to the quantum and classical equations and describe a technique to use the localization landscape method with the acoustic operator.
La Neonatologia… caso per caso
Authors: D'Agostin Martina , Catania Maria Antonietta , Giambrone Clara , Corsello Giovanni
Published: January 2023

Neonatal hypotonia, bronchopulmonary dysplasia, necrotizing enterocolitis and persistent hypoglycemia are some of the main topics in neonatology. This work aims to summarize these four neonatal conditions through illustrative clinical cases. The first issue concerns neonatal hypotonia, which can constitute a pivotal sign in the diagnosis of hypoxic ischemic encephalopathy. However, neonatal hypotonia can be present in several other conditions, such as sepsis and neurological or neuromuscular diseases. The second issue is about bronchopulmonary dysplasia, a disease that mainly affects extremely premature infants. Many therapeutic strategies have been proposed to prevent this disease, such as less invasive ventilation and an early use of inhaled and systemic corticosteroids. Long-term respiratory sequelae in infants with bronchopulmonary dysplasia remain one of the main causes of hospitalization in these children in their early years of life. The third issue is necrotizing enterocolitis, a disease that can affect both term and preterm newborns. Multiple risk factors are involved in the pathogenesis of this disease such as an abnormal peripheral perfusion due to congenital heart diseases, small for gestational age (SGA), sepsis, hypoxic-ischemic encephalopathy, chorioamnionitis, intrauterine growth restriction (IUGR). On the other hand, breastfeeding can play as a preventive factor. Finally, the last topic is about the management of persistent hypoglycaemia, a condition that can be caused by the combination of one of the following mechanisms: inadequate glucose supply in an infant with low glycogen stores (preterm, IUGR, SGA); excessive insulin production (maternal diabetes, large for gestational age); failure of counter-regulatory response to hy-poglycaemia (pituitary or adrenal deficiency
La recrudescenza delle infezioni (anche) da streptococco beta-emolitico di gruppo A?
Authors: Marchetti Federico
Published: January 2023

Since the beginning of December 2022, unusually high number of Group A Streptococcus (GAS) infec-tions among children have been reported across at least five Member States in the European Region (France, Ireland, Sweden, Holland and the United Kingdom). At the moment in Italy there has not yet been a report of an increase in cases of GAS infections, which could be either real or due to the lack of adequate monitoring. It is essential to implement adequate population monitoring systems also for GAS infections and pay particular attention to the clinical pictures that GAS can determine, both slight and dangerously invasive infections (iGAS). The increase in the cases of iGAS, as well as those from viral respiratory infections, is clearly related to the restrictions that have been adopted during the Covid-19 pandemic and only the return to the normal circulation of microbial agents will be able to avoid fur-ther infectious endemic clusters by restoring the “immune debt” phenomenon that has occurred.

Published: January 2023

O artigo discute a natureza jurídica dos dispositivos constitucionais que regulamentam a imunidade tributária religiosa. O problema do estudo é se a imunidade seria uma cláusula de garantia e, portanto, devendo ser interpretada restritivamente, ou, ao contrário, se é uma cláusula de fomento, cabendo interpretações ampliativas. A hipótese central consiste em que as interpretações extensivas são fruto de vieses balizados por interesses dos sujeitos que seriam beneficiados, de modo que, uma interpretação sistemática, à luz do ordenamento vigente e da hermenêutica jurídica, conduz à conclusão de que a imunidade tributária religiosa é uma cláusula de garantia. Metodologicamente, o artigo utiliza o método qualitativo, abordando as relações entre a teoria do discurso, a teoria do capital social e a hermenêutica jurídica; a possibilidade de antinomias e o papel da hermenêutica e, ao final, analisa os dispositivos constitucionais que regulamentam a liberdade religiosa, laicidade estatal e imunidade tributária segundo métodos e princípios da hermenêutica jurídica.

Published: January 2023

O presente trabalho busca uma resposta ao seguinte questionamento: como é tratada a proteção ante a perseguição à orientação sexual e identidade de gênero (OSIG) no Mercosul? Nesse sentido, a presente pesquisa tem como objetivo analisar como é tratada a OSIG no âmbito do Mercosul. Justifica-se a pesquisa pelo fato de que os direitos LGBTI+1 foram reconhecidos como direitos humanos em junho de 2011 por meio da Resolução no Conselho de Direitos Humanos nº A/HRC/17/L.9/56. Considerando isto, o Mercosul possui papel importante na integração dos direitos humanos, já que se baseia no Protocolo de Ushuaia sobre Compromisso Democrático no Mercosul, Bolívia e Chile, com relação ao nível demcrático dos países formadores do bloco, podendo o país violador ser suspenso das atividades no bloco econômico caso haja o descumprimento de valores democráticos, como são os direitos humanos.

Published: January 2023

A efetivação dos direitos humanos não deveria ficar sujeita à discricionariedade judicial. A construção de padrões decisórios democráticos se faz necessária. Neste sentido, a hipótese de pesquisa do presente artigo perfaz-se na elucidação do questionamento: como o amicus curiae pode ser uma importante ferramenta na oitiva dos grupos vulneráveis, daqueles que potencialmente poderão ser atingidos pela decisão judicial, ou mesmo a sociedade de modo geral? Nesta resposta reside o objetivo geral do artigo. O tema que se propõe será trabalhado por meio do método dedutivo, fundado em pesquisas bibliográficas e documentais. Conclui-se que o amicus curiae é um importante instrumento na formação democrática de padrões decisórios relacionados às questões de direitos humanos, em atenção à cidadania constitucionalmente posta e que legitima as transformações sociais

A inovação é fundamental para o desenvolvimento socioeconômico, mas tão importante quanto a criação é a proteção dos ativos intangíveis. A gestão da propriedade intelectual é uma forma de proteger as criações e agregar valor a elas. Nas incubadoras de base tecnológica, as empresas incubadas têm potencialidade de gerar novos negócios, e daí surge a necessidade da devida proteção dos ativos intangíveis. Esta pesquisa tem o objetivo de analisar como as incubadoras de base tecnológica em Santa Catarina contribuem com a gestão da propriedade intelectual dos empreendimentos incubados. Ao final, conclui-se que a gestão da propriedade intelectual nas incubadoras de base tecnológica em Santa Catarina ainda é incipiente, pois foi identificado que poucas práticas são adotadas para a proteção dos ativos intangíveis.

Background and Aim: Thrombosis within the coronary arteries causes ST-elevation myocardial infarction. STEMI can be vascularized by primary PCI, which is class-I indication and the gold standard. The present study aimed to assess the outcome of pericardial tirofiban administration in patients with ST-level myocardial infarction following primary percutaneous coronary intervention. Patients and Methods: This cross-sectional study was conducted on 228 ST-elevation myocardial infarction (STEMI) patients in the Bahawalpur Heart Center, Bahawalpur for the duration of Six months from March 2022 to September 2022. Patients of both gender having an age range 25 to 65 years with STEMI were enrolled and categorized into two groups based on Tirofiban administration are as follows: Group-I comprised of Tirofiban group and Group-II control (non-tirofiban group). All the patients underwent primary percutaneous coronary intervention (PCI). Major bleeding, MACE, TIMI Grade flow, hematoma, myocardial blush, minor bleeding, and mortality were different variables measured. SPSS version 28 was used for data analysis. Results: The overall mean age was 42.82± 10.26 years. Of the total 228 STEMI patients, there were 166 (72.8%) male and 62 (27.2%) were females. The mean age of group-I (n=114) and group-II (n=114) was 41.74 ± 11.62 years and 43.9± 8.9 years. The age-wise distribution of patients were as follows: 74 (32.5%) in 25-35 years, 70 (30.7%) in 36-45 years, 64 (28.1%) in 46-55 years, and 20 (8.8%) in 56-65 years. The prevalence of hypertension, diabetes, and smoker in Tirofiban and non-tirofiban group was 32 (28.1%) vs. 34 (29.8%), 24 (21.1%) vs. 28 (24.6%), and 31 (27.2%) vs. 33 (28.9%) respectively. A p-value of 0.05 indicated that there was an independent difference in TIMI flow grades between the two groups. Based on clinical outcomes, the incidence of partial reperfusion TIMI flow grade, normal myocardial blush grade, major bleeding, MACE, hematoma, minor bleeding, and mortality was found in 72 (31.6%), 146 (64%), 60 (26.3%), 68 (29.8%), 61 (26.8%), 52 (22.8%), and 8 (3.5%) respectively. Conclusion: The present study found that patients with severe thrombus burden and STEMI who underwent emergency coronary intervention received intracoronary tirofiban treatment that was simple, safe, and effective. A significant difference in TIMI flow and myocardial blush grades was observed when intracoronary Tirofiban was administered to STEMI patients undergoing percutaneous coronary intervention compared with patients who did not receive intracoronary Tirofiban.

Objective: The primary goal of this study is to evaluate the rates of death from coronavirus infection among healthcare personnel against those in the general population. Study Design: Comparative study Place and Duration: This study was conducted at Benazir Bhutu Hospital Rawalpindi during the period from July, 2022 to September, 2022. Methods: 135 coronavirus-infected individuals of both genders were studied. Patients were aged 20–65 years. All patients gave written consent for baseline data on age, sex, body mass index, socioeconomic status, and domicile. Patients were symptomatic and asymptomatic. Among 135 cases, 65 were health workers in group I and 70 were general population in group II. Mortality among both groups were compared. ICU hospitalization, ventilation, and death were compared between groups. SPSS 22.0 analyzed all data. Results: There were 35 males in group I with mean age 26.13±10.72 years and in group II 40 were males with mean age 45.6±5.27 years. We found that number of died patients were higher in group II 9 (12.9%) as compared to group I 3 (4.6%). Older age, heart disease, diabetes mellitus and lack of personal protective equipment (PPE) were the most common reasons of died coronavirus patients. Conclusion: The results of this study indicate that older age, heart disease, and diabetes are independently associated with a higher risk of death and a greater severity of pandemic disease among the general public than they are among health care professionals.
