Uma história de controvérsias
Authors: Both Ames Valesca Daiana , Lemos de Almeida Marilis
Published: June 2022

Neste artigo, descrevemos as controvérsias que envolveram a implantação do Aeromóvel na cidade de Porto Alegre, Rio Grande do Sul, durante o período que se estendeu do final da década de 1970 até o ano de 2013. Particularmente, identificamos os atores que participaram da construção e implantação do Aeromóvel, mapeamos suas posições e os discursos por eles formulados. Para tanto, realizamos onze entrevistas narrativas com empresários, engenheiros e políticos, bem como análise de documentos como matérias jornalísticas, relatórios técnicos, ata de audiência pública e catálogos de divulgação da tecnologia. Os resultados mostram que o processo de implantação do Aeromóvel não seguiu um caminho linear, mas foi permeado por debates e por idas e vindas, relativas ao maior apoio ou crítica que recebeu por parte de diferentes atores sociais como grupos empresariais, políticos, técnicos e a mídia.
Discurso popular-democrático e o sujeito de negação bolsonarista
Authors: José Alves Fernandes Victor , Spotorno Moreira Machado Daniel
Published: June 2022

Este artigo tem o objetivo de discutir os processos através dos quais operam-se interpelações discursivas e conformações identitárias sintetizadas no termo “bolsonarismo”. Para isso, recorremos a Ernesto Laclau e Chantal Mouffe, abordando a configuração do poder político como articulação da “hegemonia política”. Em seguida, revisitamos a problemática do conflito como categoria fundacional da psicanálise, avançando o argumento de que moções inconscientes são capazes de orientar a ação social racionalmente justificada. Enfim, argumentamos que o sujeito incapaz de relacionar-se com o mundo e com si mesmo no constante manejo e produção de alteridades é um sujeito suscetível às interpelações discursivas comuns ao autoritarismo dos matizes políticos de extrema-direita, em geral, e que chamamos “bolsonarismo”, em particular.

Published: June 2022

O objetivo deste artigo é examinar a posição do capital financeiro diante da questão trabalhista e da questão sindical na conjuntura brasileira de 2011 a 2021. Para tanto, analisamos o conteúdo a “Agenda do Setor Financeiro” produzida pela Confederação Nacional das Instituições Financeiras (CNF), órgão máximo de representação das instituições financeiras no país. Ao longo do referido período, a CNF tratou os direitos trabalhistas como inibidores do crescimento econômico, causadores do desemprego e obstáculos para a competitividade das empresas. Tal posicionamento conservador desempenhou papel relevante no debate e na elaboração de medidas que promoveram a redução de direitos trabalhistas e impuseram limites à ação reivindicatória dos trabalhadores, por meio do primado do negociado sobre o legislado, nas relações de trabalho.
Efficiency analysis of the cycloidal wave energy convertor under real-time dynamic control using a 3D radiation model
Authors: Mohtat Ali , Fagley Casey , Chitale Kedar C. , Siegel Stefan G.
Published: June 2022

Ocean waves provide a vast, uninterrupted resource of renewable energy collocated around large coastal population centers. Clean energy from ocean waves can contribute to the local electrical grid without the need for long-term electrical storage, yet due to the current high cost of energy extraction from ocean waves, there is no commercial ocean wave farm in operation. One of the wave energy converter (WEC) device classes that show the potential to enable economic energy generation from ocean waves is the class of wave terminators. This work investigates the Cycloidal Wave Energy Converter (CycWEC), which is a one-sided, lift-based wave terminator operating with coupled hydrofoils. The energy that the CycWEC extracted from ocean waves was estimated using a control volume analysis model of the 3D wave field in the presence of the CycWEC. The CycWEC was operated under feedback control to extract the maximum amount of energy possible from the incoming waves, and the interaction with different incoming regular, irregular, and short crested waves was examined.

Variability is one of the main observational characteristics of blazars. Studying variability is an efficient method to reveal the nature of active galactic nuclei. In the present work, we report optical R-band photometry observations of a TeV blazar, 1ES 2344 + 514, carried out with a 70 cm telescope in the period of 1998 July–2017 November at Abastumani Observatory, Georgia. Based on the optical R-band observations, the optical variation behaviors on both short timescales and long timescales are investigated. Three methods (Jurkevich, discrete correlation function, and power spectrum analysis) are used to investigate periodicity in the light curve. In addition, combined with multiwavelength data, the jet physical properties are discussed. The following conclusions are drawn: (1) A variability of ΔR = 0.155 mag (15.356 − 15.201 mag) over a timescale of ΔT = 12.99 minutes is detected during our 628 days of monitoring. (2) According to the Kelvin–Helmholtz thermal instability, if the magnetic field intensity (B) for the source is greater than a critical value (B

c
), it will reduce the incidence of intraday variations in the light curves. (3) The physical parameters of the dissipation region are obtained by fitting the spectral energy distribution with a one-zone synchrotron self-Compton model for the average and flare states. (4) The three methods show that there are periods of P = 2.72 ± 0.47 yr, P = 1.61 ± 0.18 yr, P = 1.31 ± 0.17 yr, and P = 1.05 ± 0.07 yr. When a binary black hole system is adopted with a period of P = 2.72 ± 0.41 yr, we obtain the orbital parameters for the binary black hole system as follows: M = 8.08 × 109
M
⊙, the sum of the semiaxes is r = 7.18 × 1016 cm, and the lifetime of the binary black hole is τ

Scalar Quadratic Maximum-likelihood Estimators for the CMB Cross-power Spectrum
Authors: Chen Jiming , Ghosh Shamik , Zhao Wen
Published: June 2022

Estimating the cross-correlation power spectra of the cosmic microwave background, in particular, the TB and EB spectra, is important for testing parity symmetry in cosmology and diagnosing insidious instrumental systematics. The quadratic maximum-likelihood (QML) estimator provides optimal estimates of the power spectra, but it is computationally very expensive. The hybrid pseudo-C

ℓ
estimator is computationally fast but performs poorly on large scales. As a natural extension of previous work, in this article, we present a new unbiased estimator based on the Smith–Zaldarriaga (SZ) approach of E–B separation and the scalar QML approach to reconstruct the cross-correlation power spectrum, called the QML-SZ estimator. Our new estimator relies on the ability to construct scalar maps, which allows us to use a scalar QML estimator to obtain the cross-correlation power spectrum. By reducing the pixel number and algorithm complexity, the computational cost is nearly one order of magnitude smaller and the running time is nearly two orders of magnitude faster in the test situations.
Principal Component Analysis in the Modeling of Colors of Comae of Comets Hale-Bopp and Tabur
Authors: Betzler Alberto S.
Published: June 2022

The temporal variability of the colors of comae of comets has been reported for some decades. The color indices B-R of comets Hale-Bopp and Tabur were estimated with a variation of the model of Kolokolova et al., according to geometrical, populational, and compositional parameters of cometary dust. A principal component analysis of five model parameters points that the variation of these color indices is usually associated with changes in population or geometric parameters, and their extremes with a compositional variation of the dust grains.

This review provides an analysis of activities undertaken by the Mars 2020 Council of Atmospheres (CoA) in support of the entry, descent, and landing (EDL) of the Mars 2020 rover Perseverance in Jezero crater, Mars. The activities of the CoA were designed to evaluate the safety of early-stage landing site candidates and, later, to constrain the range of plausible conditions expected at Jezero crater during the early northern spring season of EDL, following the successful blueprint of similar councils for prior landed Mars missions. The multiyear effort of the CoA involved using a combination of numerical modeling of the local Martian atmosphere with limited-domain mesoscale models and atmospheric reanalysis using data assimilation techniques, along with atmospheric observations from multiple orbiting assets, to generate an atmospheric “forecast” for the day of landing. Here we present an overview of these activities, focusing in greater detail on those elements that depart from prior CoA activities as performed for Mars Phoenix, Mars Science Laboratory, and the InSight lander. Following the successful landing of Perseverance on 2021 February 18, reconstruction and reassessment activities were performed and are presented here, comparing prelanding predictions with actual, as-flown conditions.

With the rapid development of urbanization, the habitat quality (HQ) in urban areas has been eroded. This phenomenon is destroying the balance of ecosystems, triggering the reduction of biodiversity and the decay of ecosystem service functions. The study of the relationship between urbanization and HQ in Zhengzhou City is beneficial for the reference of sustainable urban ecological planning and management. Based on landscape classification data and socioeconomic data for three years, this study analyzes the spatial correlations between socioeconomic and landscape pattern factors and HQ, compares the dynamic changes in the explanatory power of different factors, and explores the joint effects between multiple factors. The results show that: (1) The overall value of HQ index in Zhengzhou City decreased by .10 during 2000–2020, mainly occurring in suburban areas, with a small amount of HQ improvement occurring in the core areas of ecological protection, such as mountains and river channels. (2) The spatial autocorrelation of all influencing factors with HQ increased during this period, while the negative impact from socio-economic sources was stronger than the positive impact from landscape patterns. (3) Intensive human activities lead to a single habitat type, which reduces HQ; rich landscape types and complex landscape composition can enhance HQ. Improving the connectivity of blue-green landscapes helps to attenuate the negative effects of urbanization on HQ. (4) Changes of HQ in the study area and the development of multi-factor effects on HQ are driven by the Zhengzhou Metropolitan Area Plan. Urban development policies and management can build idyllic complexes at the edge of urban development, preserving pristine blue-green patches to avoid their homogenized distribution and thus slowing the decline of HQ. The above results provide new ideas for the development of sustainable urban ecology.
The turbinal skeleton of Pentalagus furnessi (Leporidae, Lagomorpha)
Authors: Ruf Irina
Published: June 2022

The turbinal skeleton inside the nasal cavity supports the respiratory and olfactory epithelia of the mammalian nose and can provide systematic and morphofunctional information. For the first time, the turbinal skeleton of Pentalagus furnessi (Amami rabbit) from Japan is described based on µCT scans and virtual 3D reconstructions of two specimens. In general, the turbinal skeleton of Pentalagus furnessi resembles the pattern and characters observed in other Leporidae. The maxilloturbinal is highly dendritic, nasoturbinal and crista semicircularis are in close contact and form a common recess, the frontoturbinal recess houses two frontoturbinals and one interturbinal between them, the ethmoturbinal recess houses three ethmoturbinals and one interturbinal between ethmoturbinal I and II. Pentalagus furnessi is derived from the leporid grundplan in having a lamina semicircularis with almost straight posterior margin and ventral lamella and in showing a single-scrolled and relatively short interturbinal between frontoturbinal 1 and 2. These characters can be regarded as autapomorphic for the Amami rabbit. Furthermore, the two specimens have an additional small and short interturbinal between frontoturbinal 2 and ethmoturbinal I that shows some variation. This pattern supports previous observations of intraspecific variation of certain interturbinals in Oryctolagus cuniculus and some Sylvilagus and Lepus species. The comparison of the turbinal skeleton of Pentalagus furnessi and its possible sister taxon (e.g., Pronolagus, Poelagus or Caprolagus) reveals a puzzling pattern which is discussed.
On multiple scattering in Compton scattering tomography and its impact on fan-beam CT
Authors: Kuger Lorenz , Rigaud Gaël
Published: June 2022

The recent development of energy-resolving scintillation crystals opens the way to new types of applications and imaging systems. In the context of computerized tomography (CT), it enables to use the energy as a dimension of information supplementing the source and detector positions. It is then crucial to relate the energy measurements to the properties of Compton scattering, the dominant interaction between photons and matter. An appropriate model of the spectral data leads to the concept of Compton scattering tomography (CST). Multiple-order scattering constitutes the major difficulty of CST. It is, in general, impossible to know how many times a photon was scattered before being measured. In the literature, this nature of the spectral data has often been eluded by considering only the first-order scattering in models of the spectral data. This consideration, however, does not represent the reality as second- and higher-order scattering are a substantial part of the spectral measurement. In this work, we propose to tackle this difficulty by an analysis of the spectral data in terms of modeling and mapping properties. Due to the complexity of the multiple order scattering, we model and study the second-order scattering and extend the results to the higher orders by conjecture. The study ends up with a general reconstruction strategy based on the variations of the spectral data which is illustrated by simulations on a joint CST-CT fan beam scanner. We further show how the method can be extended to high energetic polychromatic radiation sources.
Characterizations of Fock-type spaces of eigenfunctions on $ \mathbb{R}^n $
Authors: Fu Xi , Xie Xiaoqiang
Published: June 2022

In this paper, we prove a norm equivalence for an exponential type weighted integral of an eigenfunction and its derivative on $ \mathbb{R}^n $. As applications, we characterize Fock-type spaces of eigenfunctions on $ \mathbb{R}^n $ in terms of Lipschitz type conditions and double integral conditions. These obtained results are extensions of the corresponding ones in classcial Fock space.
Stationary distribution and extinction of a stochastic influenza virus model with disease resistance
Authors: Xin Ming-Zhen , Wang Bin-Guo , Wang Yashi
Published: June 2022

Influenza is a respiratory infection caused influenza virus. To evaluate the effect of environment noise on the transmission of influenza, our study focuses on a stochastic influenza virus model with disease resistance. We first prove the existence and uniqueness of the global solution to the model. Then we obtain the existence of a stationary distribution to the positive solutions by stochastic Lyapunov function method. Moreover, certain sufficient conditions are provided for the extinction of the influenza virus flu. Finally, several numerical simulations are revealed to illustrate our theoretical results. Conclusively, according to the results of numerical models, increasing disease resistance is favorable to disease control. Furthermore, a simple example demonstrates that white noise is favorable to the disease's extinction.
Macrophytes distribution in the karstic river Rak and an assessment of the state of the aquatic system / Razporeditev makrofitov v kraški reki Rak in ocena stanja vodnega ekosistema

The karst is a geographically and geologically highly dynamic area strongly dependent on water activity. This includes intermittent water bodies which have a specific impact on nearby environment. Sessile organisms such as plants have to adapt to extreme changes in water availability. Their presence, distribution and abundance can therefore serve as indicators of the ecological status of the water ecosystems. Using the modified Riparian, Channel, and Environmental (RCE) inventory method, we ranked the Rak River in the highest RCE quality classes. Based on the RMI (River Macrophyte Index), we classified the Rak River to good or very good ecological status. The good ecomorphological preservation of the Rak River probably also contributes to the presence of endangered plant species; among the 38 taxa listed, we detected the presence of eleven species included in Slovenian Red list of threatened pteridophytes and seed plants. At the time of our sampling, the species Zannichellia palustris was detected for the first time in this river. The high assessment of the preservation of the intermittent karst river Rak confirms the current good management and is important in the implementation of nature protection guidelines for the future.
 
IZVLEČEK
Kraški svet predstavljajo geografsko in geološko izjemno dinamična območja, ki so močno povezana z delovanjem vode. Presihajoča vodna telesa v kraškem svetu s svojim delovanjem močno vplivajo na okolje. V največji meri se morajo na velike spremembe dostopnosti vode prilagajati sesilni organizmi, kakršni so rastline. Njihova prisotnost, abundanca in razporeditev lahko služijo kot indikatorji stanja vodnih ekosistemov. S pomočjo prirejene metode RCE (ang. A Riparian, Channel, and Environmental Inventory) smo reko Rak uvrstili v najvišje RCE kakovostne razrede. Na osnovi indeksa RMI (ang. River Macrophyte Index) smo reko Rak uvrstili v dobro oz. zelo dobro ekološko stanje. Dobra ekomorfološka ohranjenost reke Rak verjetno botruje tudi pojavljanju ogroženih rastlinskih vrst; med 38 popisanimi taksoni smo zaznali prisotnost enajstih vrst, ki so uvrščene na Rdeči seznam ogroženih praprotnic in semenk. V času našega vzorčenja je bila v tej reki prvič zaznana vrsta Zannichellia palustris. Visoka ocena ohranjenosti presihajoče kraške reke Rak potrjuje dosedanje dobro upravljanje in je pomembna pri udejanjanju naravovarstvenih smernic za prihodnost.

Published: June 2022

This chapter presents pedagogical adaptation in higher learning institutions (HLIs) during the pandemic in Tanzania. The study employed a phenomenological research design under the qualitative research approach. Twenty-four respondents, including university lecturers and students from five selected universities, participated in the study. Data collection used an unstructured interview guide. Data analysis employed content and thematic analysis methods. The findings revealed that universities employed different pedagogical approaches such as online learning, lecturing in small groups, and extending the timetable. Institutions supported pedagogical adaptation by building academic staff capacity to use online platforms and providing necessary facilities. Further, the main challenges were the digital divide among students and limited skills for both students and teachers to manage online learning. Future studies should investigate how programmes that require practical sessions such as engineering, agriculture, and vocational education implemented pedagogical innovations.
