DESAFIOS NA APLICAÇÃO DE SALA DE AULA INVERTIDA NA ENGENHARIA CIVIL – UM RELATO DE EXPERIÊNCIA

O ensino a nível de graduação requer inovações constantes de seus métodos para incentivar a partipação dos alunos. As metodologias ativas, aqui tratadas como “sala de aula invertida” e “aprendizado híbrido”, surgem como estratégias para propiciar um ambiente mais dinâmico tendo por base a solução de problemas, ao invés das aulas estritamente expositivas. Identifica-se então um desafio a ser encarado pelos docentes no ensino de graduação. Nesse sentido, este trabalho tem como objetivo relatar um estudo de caso dos autores com a aplicação de sala de aula invertida, mesclada com as outras estratégias descritas, numa disciplina da graduação de Engenharia Civil em uma Universidade Pública Federal. Resultados são apresentados tendo por base questionários preenchidos pelos discentes no final do semestre, além de uma comparação entre as médias finais com a metodologia tradicional, e o relato das lições aprendidas. Como contribuições tem-se a possibilidade de replicação e adaptação em outras disciplinas, além de uma análise crítica sobre as etapas aplicadas e as dificuldades constatadas. Apesar dos obstáculos encontrados, encoraja-se veementemente a mudança dos paradigmas educacionais e a busca por novas formas de ensino que acompanhem as tendências globais.
Quantum critical point in the superconducting transition on the surface of a topological insulator

Pairing in the Weyl semi - metal appearing on the surface of topological insulator is considered. It is shown that due to an "ultra-relativistic" dispersion relation there is a quantum critical point governing the zero temperature transition to a superconducting state. Starting from the microscopic Hamiltonian with local attraction, we calculated using the Gor'kov equations, the phase diagram of the superconducting transition at arbitrary chemical potential, its magnetic properties and critical exponents close to the quantum critical point. The Ginzburg - Landau effective theory is derived for small chemical potential allowing to consider effects of spatial dependence of order parameters in magnetic field. The GL equations are very different from the conventional ones reflecting the chiral universality class of the quantum phase transition. The order parameter distribution of a single vortex is found to be different as well. The magnetization near the upper critical field is found to be quadratic, not linear as usual. We discuss the application of these results to recent experiments in which surface superconductivity was found that some 3D topological insulators and estimate feasibility of the phonon pairing.
Portfolios under Constraints in Real Practice

Portfolio optimization now has a decisive status in the financial researching. However, few research focus on several specific industries and the commonly used constraints in the realistic financial world. This paper aims to do the asset allocation for three industries, i.e., technology industry, financial service industry and industrial industry. The SPX500 and ten firms from the above industries are chosen to obtain their correlation coefficient matrix. Then Mean-Variance Model is used to calculate the maximum Sharpe Ratio, the minimum variance, the capital allocation line. Finally, solver table is applied to calculate the minimum variance frontier under each constraint. The result shows that, first, the SPX500 has a high correlation coefficient with the listed firms, and it’s a good choice in a portfolio that balances risk and return; second, the minimum variance frontier and capital allocation line behave worse when adding constraints. These findings may help the investors with specific risk appetite to make their own investment decisions. Besides, investors will be aware of the price of adding constraints when making a investment decision.
The Influence of Compatibility and Technology Acceptance Model Toward Intention to Use E-Wallet During Covid-19

Since Covid-19, cashless especially e-wallet has become a trend in Indonesia. This was caused by the compatibility between e-wallet with the Indonesian lifestyle primarily when the Covid-19 protocol was applied and also could be used for a continuous purpose. This research was done to analyze the impact of compatibility and the Technology Acceptance Model (TAM) on the intention to use e-wallets. The technology acceptance model (consisting of perceived ease of use, and perceived usefulness) is used to underpin the research framework. The data collected in this study are from college students who are living in Indonesia and using e-wallet. The measurement will be adapted from previous research in which the reliability and validity are confirmed using pre-testing. SPSS and SmartPLS are used to analyze the data. The output could become a contribution for the development of the TAM model in relation to the intention to use e-wallet among college students in Indonesia. In addition, the result could become an insight to understand consumer behaviors when using e-wallet.
Creating an Escape Room for Cultural Mediation: Insights from "The Archivist's Dream"

The Archivist’s Dream („Der Traum der Archivarin“) is a Live Escape Room Game that has been developed by the University of Krems’ Center for Applied Game Studies on behalf of the Archives of Contemporary Arts in Krems, Austria, which are dedicated to collecting pre-mortem bequests and post-mortem estates of outstanding artists. Located in the underground facilities of the archive, the Escape Room interweaves selected archival materials, historic media devices and archivist approaches to form an interactive puzzle experience. However, it is not an interactive exhibition showcasing the archives’ contents; and while the Escape Room incorporates elements of educational game design, it is an example for a less common application of (Escape Room) Games: the use of game design in the field of cultural mediation (Kulturvermittlung). Instead of following an educational goal in the narrower sense, the Escape Room is designed to turn aspects of cultural mediation and archival practice into gameplay principles, focusing on letting players explore the tenets of archival thinking rather than on “teachable” content. This is achieved by establishing different levels of (un-)reality players have to travers within the game: players follow a fictional archivist into her dreams, which merge with the real-life archives. In order to “escape” this dream world, players combine archival practices with dream logic to solve a secret tied to actual archival materials, while at the same time dissolving the borders between real life, dream and game.
X-ray–optical classification of cluster mergers and the evolution of the cluster merger fraction

We present the results of a simple but robust morphological classification of a statistically complete sample of 108 of the most X-ray-luminous clusters at 0.15 ≤z≤ 0.7 observed with Chandra. Our aims are to (a) identify the most disturbed massive clusters to be used as gravitational lenses for studies of the distant Universe and as probes of particle acceleration mechanisms resulting in non-thermal radio emission; (b) find cluster mergers featuring subcluster trajectories that make them suitable for quantitative analyses of cluster collisions; and (c) constrain the evolution with redshift of the cluster merger fraction. Finally, (d) this paper represents the third public release of clusters from the MAssive Cluster Survey sample, adding 24 clusters to the 46 published previously. To classify clusters by the degree of relaxation, we use the projected offset of the brightest cluster galaxy from the peak (or the global centroid) of the X-ray emission as a measure of the segregation between the intracluster gas and dark matter, and also perform a visual assessment of the optical and X-ray morphology on all scales. Regarding (a), we identify 10 complex systems likely to have undergone multiple merger events in the recent past. Regarding (b), we identify 11 systems likely to be post-collision, binary, head-on mergers (BHOMs), as well as another six mergers that are possible BHOMs but probably harder to interpret because of non-negligible impact parameters and merger axes closer to our line of sight. Regarding (c), we find a highly significant increase with redshift in the fraction of morphologically disturbed clusters (and thus a clear decrease in the number of fully relaxed systems) starting at z∼ 0.4, in spite of a detection bias in our sample against very disturbed systems at high redshift. Since our morphological diagnostics are all based on imaging data and thus sensitive to projection effects, the measured merger fractions should be considered lower limits and our list of mergers incomplete, as we are likely to miss systems forming along axes close to our line of sight. A larger sample of clusters with high-quality X-ray data in particular at high redshift will be needed to trace the evolutionary history of cluster growth and relaxation closer to the primary epoch of cluster formation z∼ 1.
A Consistent Picture of a Collapsing Bose-Einstein Condensate (Waseda International Symposium on Fundamental Physics--New Perspectives in Quantum Physics) -- (Chapter 3. Bose-Einstein Condensation)

We present a consistent picture of the recent JILA experiments on the collapse of a Bose–Einstein condensate (BEC) [E. A. Donley et al. : Nature 412 (2001) 295] based on a generalized Gross–Pitaevskii equation that incorporates the effect of a three-body loss. The questions we address in this paper are: (1) Why does a BEC survive, albeit partially, after the collapse? (2) Why does the number of the remnant BEC atoms observed at JILA exceed the critical value? (3) What is the origin of the atom burst? (4) What is the origin of the atom jet and is it coherent? We review our predictions on pattern formation in the course of collapse and on the split instability of vortices that can test our collapsing theory.
Observations of low‐elevation ionospheric anomalies for ground‐based augmentation of GNSS

Extreme ionospheric anomalies occurring during severe ionospheric activity can pose an integrity threat to users of Global Navigation Satellite System (GNSS) Ground Based Augmentation Systems (GBAS). While most very large spatial gradients in slant ionospheric delay were observed on high‐elevation satellites, several extreme gradients were also observed on satellites below 15 degrees elevation. This paper details the study of anomalous ionospheric spatial gradients for low‐elevation satellites observed from the 20 November 2003 geomagnetic storm in the Conterminous United States (CONUS). As viewed by a cluster of Continuously Operating Reference Stations (CORS) receivers in northern Ohio, SVN 26 came into view around 20:30 Universal Time (UT) on this day, rose to an elevation angle of about 15 degrees, and set around 22:00 UT. A spatial gradient of 360 mm/km was discovered at 21:20 UT between CORS stations GARF and WOOS, when SVN 26 was at 11 degrees elevation. Ionospheric delay measurements are vulnerable to semi‐codeless L2 tracking errors and data post‐processing errors, especially when satellites are at low elevation. This paper presents a series of methods to validate observed ionospheric anomaly events using station‐wide checks, satellite‐wide checks, and manual verification with single‐frequency measurements. Spatial gradients discovered at other station pairs and another low elevation satellite with a similar azimuth angle, SVN 29, support that the event of SVN 26 is an ionospheric anomaly as opposed to a receiver fault.
The multiplex relations between cities: a lexicon-based approach to detect urban systems

ABSTRACT Cities relate to other cities in many ways, and much scholarly effort goes into uncovering those relationships. Building on the principle that strongly related cities will co-occur frequently in texts, we propose a novel method to classify those toponym co-occurrences using a lexicon-based text-mining method. Millions of webpages are analysed to retrieve how 293 Chinese cities are related in terms of six types: industry, information technology, finance, research, culture and government. Each class displays different network patterns, and this multiplexity is mapped and analysed. Further refinement of this lexicon-based approach can revolutionize the study of inter-urban relationships.
Jack, The Autotuner

Among his many technical contributions, automated performance tuning—or autotuning—has been a critical pillar of the research that has emerged from Jack Dongarra’s group at the University of Tennessee. This article reflects on the history of that work, including an analysis of the large body of research that has used or cited the ATLAS system since its inception in the late 1990s.
Valley separation in graphene by polarized light

We show that the optical excitation of graphene with polarized light leads to the pure valley current where carriers in the valleys counterflow. The current in each valley originates from asymmetry of optical transitions and electron scattering by impurities owing to the warping of electron energy spectrum. The valley current has strong polarization dependence, its direction is opposite for normally incident beams of orthogonal linear polarizations. In undoped graphene on a substrate with high susceptibility, electron-electron scattering leads to an additional contribution to the valley current that can dominate.
Ischemic Stroke, Lessons from the Past towards Effective Preclinical Models

Ischemic stroke is a leading cause of death worldwide, mainly in western countries. So far, approved therapies rely on reperfusion of the affected brain area, by intravenous thrombolysis or mechanical thrombectomy. The last approach constitutes a breakthrough in the field, by extending the therapeutic window to 16–24 h after stroke onset and reducing stroke mortality. The combination of pharmacological brain-protective strategies with reperfusion is the future of stroke therapy, aiming to reduce brain cell death and decrease patients’ disabilities. Recently, a brain-protective drug—nerinetide—reduced brain infarct and stroke mortality, and improved patients’ functional outcomes in clinical trials. The success of new therapies relies on bringing preclinical studies and clinical practice close together, by including a functional outcome assessment similar to clinical reality. In this review, we focused on recent upgrades of in vitro and in vivo stroke models for more accurate and effective evaluation of therapeutic strategies: from spheroids to organoids, in vitro models that include all brain cell types and allow high throughput drug screening, to advancements in in vivo preclinical mouse stroke models to mimic the clinical reality in surgical procedures, postsurgical care, and functional assessment.
The Life Cycle Model and Press Coverage of Nordic Populist Parties Herkman,

The article traces the life cycles of the Nordic populist parties by exploring the relationship between media coverage and contemporary populist parties in Finland (Finns Party), Sweden (Sweden Democrats), Norway (Norwegian Progress Party) and Denmark (Danish People’s Party). Empirically the study is based on a content analysis of 3,337 journalistic articles published in the leading quality and popular newspapers of Finland, Sweden, Norway and Denmark during the first parliamentary elections of the 2010s. The analysis confirms the life cycle model introduced in Mazzoleni et al. (2003) The Media and Neo-Populism, which found that parties in their insurgent phase gained more media attention than parties in their established phase. This study found populism currently a more important topic in Finland and Sweden, where populist movements were entering parliament, whereas in Norway and in Denmark, after long-term success, the domestic populist parties had become more mainstream and their media attention normalized. The popular newspapers tended to be more positive about populist parties than quality papers. However, these results can be explained partly by journalistic routines and by country-specific political conditions. Thus, further research is needed to prove the life cycle model.
Formation and Evolution of the Dust in Galaxies. II. The Solar Neighbourhood

Context. Over the past decade a new generation of chemical models, in addition to the gas, have included the dust in the treatment of the interstellar medium (ISM). This major accomplishment has been spurred by the growing amounts of data on the highly obscured high-z Universe and the intriguing local properties of the Solar Neighbourhood (SoNe) of the Milky Way (MW) Disk. Aims. We present here a new model able to simulate the formation and evolution of dust in the ISM of the MW. The model follows the evolution of 16 elemental species, with particular attention to those that are simultaneously present in form of gas and dust, e.g. C, N, O, Mg, Si, S, Ca and Fe. In this study we focus on the SoNe and the MW Disk as a whole which are considered as laboratories to test the physical ingredients governing the dust evolution. Methods. The MW is described as a set of concentric rings of which we follow the time evolution of gas and dust. Infall of primordial gas, birth and death of stars, radial flows of matter between contiguous shells, presence of a central bar, star-dust emission by SNae and AGB stars, dust destruction and accretion are taken into account. The model reproduces the local depletion of the elements in the gas, and simultaneously satisfies other constraints obtained from the observations. Results. The evolution of the element abundances in the gas and dust has been well reproduced for plausible choices of the parameters. The Mg/Si ratio, in particular, drives the formation of silicates. We show that for most of the evolution of the MW, the main process for dust enrichment is the accretion in the cold regions of the ISM. SNae dominate in the early phases of the evolution. We have also examined the main factors controlling the temporal window in which SNae govern the dust budget both in low and high star forming environments. The role played by AGB stars is also discussed. We find that IMFs with regular slope in the range of massive stars better reproduce the observed depletions. Conclusions. The classical chemical models nicely reproduce the abundances, depletion factors and dust properties of the SoNe and the main ingredients of the models are tested against observational data. The results obtained for the SoNe lead us to safely extend the model to the whole Galactic Disk or galaxies of different morphological types.
Hospital Acquired Pathogenic Escherichia coli from Clinical and Hospital Water Samples of Quetta Balochistan

A study was conducted to determine the prevalence and drug resistance of Escherichia coli present in urinary tract infected patients and hospital drinking water. A total of eighty urine samples from clinically suspected patients and thirty tap water samples from hospital vicinity were collected and analyzed for the presence of E. coli. The isolates were preliminary identified based on morphological characteristics, biochemical test and further confirmed by polymerase chain reaction (PCR) using uidA primer. Isolates were subjected to antibiogram studies and analyzed for the presence of drug resistance (ESBL blaCTX-M-15, tetA, and TMP-SMX dfrA1) and pathogenicity associated pyelonephritis-associated pili (PAP) and Heat-labile (LT) toxin genes. Urine samples 19/80 (23.75%) and water samples 8/30 (26.7%) were found contaminated with E. coli. It was found that 12/19 (63%) bacterial isolates were extended spectrum beta-lactamase (ESBL) producers in clinical and 6/8 (75%) in water isolates whereas tetracycline resistance in clinical and water isolates was 11/19 (58%) and 6/8 (75%), respectively. The trimethoprim resistance gene was confirmed in 12/19 (63%) in clinical and 2/8 (25%) in water isolates. All the clinical and water isolates were found carrying pili PAP gene. It was concluded that the presence of drug resistant and pathogenic E. coli in clinical and water samples is extremely alarming for public health due to cross contamination and bacterial transfer from clinical samples to water and vice versa.
Comparative Evaluation of Tumor-Infiltrating Lymphocytes in Companion Animals: Immuno-Oncology as a Relevant Translational Model for Cancer Therapy

Simple Summary Laboratory experiments studying solid tumors are limited by the inability to adequately model the tumor microenvironment and important immune interactions. Immune cells that infiltrate the tumor bed or periphery have been documented as reliable biomarkers in human studies. Veterinary oncology provides a naturally occurring cancer model that could complement biomarker discovery, clinical trials, and drug development. Abstract Despite the important role of preclinical experiments to characterize tumor biology and molecular pathways, there are ongoing challenges to model the tumor microenvironment, specifically the dynamic interactions between tumor cells and immune infiltrates. Comprehensive models of host-tumor immune interactions will enhance the development of emerging treatment strategies, such as immunotherapies. Although in vitro and murine models are important for the early modelling of cancer and treatment-response mechanisms, comparative research studies involving veterinary oncology may bridge the translational pathway to human studies. The natural progression of several malignancies in animals exhibits similar pathogenesis to human cancers, and previous studies have shown a relevant and evaluable immune system. Veterinary oncologists working alongside oncologists and cancer researchers have the potential to advance discovery. Understanding the host-tumor-immune interactions can accelerate drug and biomarker discovery in a clinically relevant setting. This review presents discoveries in comparative immuno-oncology and implications to cancer therapy.
Micromachined Thermal Time-of-Flight Flow Sensors and Their Applications

Micromachined thermal flow sensors on the market are primarily manufactured with the calorimetric sensing principle. The success has been in limited industries such as automotive, medical, and gas process control. Applications in some emerging and abrupt applications are hindered due to technical challenges. This paper reviews the current progress with micromachined devices based on the less popular thermal time-of-flight sensing technology: its theory, design of the micromachining process, control schemes, and applications. Thermal time-of-flight sensing could effectively solve some key technical hurdles that the calorimetric sensing approach has. It also offers fluidic property-independent data acquisition, multiparameter measurement, and the possibility for self-calibration. This technology may have a significant perspective on future development.
An Aminopyrimidone and Aminoimidazoles Alkaloids from the Rodrigues Calcareous Marine Sponge Ernsta naturalis

A chemical study of the CH2Cl2−MeOH (1:1) extract from the sponge Ernsta naturalis collected in Rodrigues (Mauritius) based on a molecular networking dereplication strategy highlighted one novel aminopyrimidone alkaloid compound, ernstine A (1), seven new aminoimidazole alkaloid compounds, phorbatopsins D–E (2, 3), calcaridine C (4), naamines H–I (5, 7), naamidines J–K (6, 8), along with the known thymidine (9). Their structures were established by spectroscopic analysis (1D and 2D NMR spectra and HRESIMS data). To improve the investigation of this unstudied calcareous marine sponge, a metabolomic study by molecular networking was conducted. The isolated molecules are distributed in two clusters of interest. Naamine and naamidine derivatives are grouped together with ernstine in the first cluster of twenty-three molecules. Phorbatopsin derivatives and calcaridine C are grouped together in a cluster of twenty-one molecules. Interpretation of the MS/MS spectra of other compounds of these clusters with structural features close to the isolated ones allowed us to propose a structural hypothesis for 16 compounds, 5 known and 11 potentially new.
