The aims of this study were to investigate the feasibility of using a DLP 3D printer to fabricate a crown using scan data before tooth preparation, and to investigate the effect of additional heat curing on the mechanical properties of the urethane dimethacrylate (UDMA)-based 3D printed crown. A silicone fitting test was used to evaluate the internal adaptation of the crown. For ultimate tensile strength (UTS), the specimens were tested after 24 h storage in water at 37 °C or after 10,000 thermal cycles (TC) between 5–55 °C. For shear bond strength (SBS), a PMMA self-curing resin was filled into a Teflon ring mounted onto the polished UDMA specimens. The internal adaptation of the crowns fabricated with cement space was better than those with no cement space. There was no significant difference in UTS between light-curing and additional heat-curing groups after TC. As for the SBS, there was a significant difference after TC between the two groups. Crowns can be fabricated by a DLP 3D printer using pre-preparation scans with a cement space defined in the software. Additional heat curing of the UDMA-based crown reduced residual monomer and improved its mechanical properties.

Published: May 2021

Structural health monitoring for offshore wind turbine foundations is paramount to the further development of offshore fixed wind farms. At present time there are a limited number of foundation designs, the jacket type being the preferred one in large water depths. In this work, a jacket-type foundation damage diagnosis strategy is stated. Normally, most or all the available data are of regular operation, thus methods that focus on the data leading to failures end up using only a small subset of the available data. Furthermore, when there is no historical precedent of a type of fault, those methods cannot be used. In addition, offshore wind turbines work under a wide variety of environmental conditions and regions of operation involving unknown input excitation given by the wind and waves. Taking into account the aforementioned difficulties, the stated strategy in this work is based on an autoencoder neural network model and its contribution is two-fold: (i) the proposed strategy is based only on healthy data, and (ii) it works under different operating and environmental conditions based only on the output vibration data gathered by accelerometer sensors. The proposed strategy has been tested through experimental laboratory tests on a scaled model.

Published: May 2021

Existing government air quality monitoring networks consist of static measurement stations, which are highly reliable and accurately measure a wide range of air pollutants, but they are very large, expensive and require significant amounts of maintenance. As a promising solution, low-cost sensors are being introduced as complementary, air quality monitoring stations. These sensors are, however, not reliable due to the lower accuracy, short life cycle and corresponding calibration issues. Recent studies have shown that low-cost sensors are affected by relative humidity and temperature. In this paper, we explore methods to additionally improve the calibration algorithms with the aim to increase the measurement accuracy considering the impact of temperature and humidity on the readings, by using machine learning. A detailed comparative analysis of linear regression, artificial neural network and random forest algorithms are presented, analyzing their performance on the measurements of CO, NO2 and PM10 particles, with promising results and an achieved R2 of 0.93–0.97, 0.82–0.94 and 0.73–0.89 dependent on the observed period of the year, respectively, for each pollutant. A comprehensive analysis and recommendations on how low-cost sensors could be used as complementary monitoring stations to the reference ones, to increase spatial and temporal measurement resolution, is provided.
Calculation of AeroMACS Spectrum Requirements Based on Traffic Simulator
Authors: Shin Hong-Gi , Kim Hyung-Jung , Lee Sang-Wook , Yoon Hyun-Goo , Choi Yong-Hoon
Published: May 2021

In this paper, we propose a methodology for calculating the necessary spectrum requirements of aeronautical mobile airport communication system (AeroMACS) to provide various airport communication services. To accurately calculate the spectrum requirement, it is necessary to evaluate the AeroMACS traffic demand of the peak time and statistical data on the packet traffic generated at the airport. Because there is no AeroMACS traffic model and real trace data, we have developed the AeroMACS traffic simulator based on the report of Single European Sky Air Traffic Management Research (SESAR). To calculate the spectrum requirements, the AeroMACS traffic simulator is combined with the methodology of ITU-R M.1768-1. The developed traffic simulator reflects AeroMACS traffic priorities and can generate the required traffic according to its location in the airport. We observed the spectrum requirement by changing the number of sectors and the spectral efficiency. To show the feasibility of our methodology, we applied it to the case of Incheon International Airport in Korea. The simulation results show that the average bandwidth of 0.94 MHz is required in the ground area and 8.59 MHz is required in the entire airport.
Assessing the Greenhouse Gas Impact of a Renewable Energy Feed-in Tariff Policy in Mozambique: Towards NDC Ambition and Recommendations to Effectively Measure, Report, and Verify Its Implementation

Published: May 2021

Parties to the Paris Agreement (PA) have agreed on the goal of limiting the increase in global average temperature to well below 2 °C and are pursuing efforts to limit warming to 1.5 °C. Countries’ nationally determined contributions (NDCs) comprise the main framework used to achieve this. In this context, Mozambique′s NDC includes, amongst other actions, increased renewable energy (RE) generation. This article presents the results of the assessment of greenhouse gas (GHG) impacts of the Renewable Energy Feed-in Tariff (REFIT), using the Long-range Energy Alternatives Planning (LEAP) system model, in order to determine its potential contribution to Mozambique′s NDC’s goals and RE targets. Results from this study show that the REFIT regulation can be expected to contribute to reducing 0.34 MtCO2eq (0.6% of the NDC target for the electricity sector) by 2030, compared to a business-as-usual (BAU) scenario. However, the NDC ambition could be enhanced through the REFIT and contribute to reducing 2.54 MtCO2eq (4.3% of the NDC target for the electricity sector) by 2030. The article further discusses the requirements for a robust measuring, reporting, and verification (MRV) system for climate policies, using REFIT as a case study, to facilitate effective tracking of NDC progress and achievement and transparent reporting to the United Nations Framework Convention on Climate Change (UNFCCC).
Rewizyta etnograficzna. Jak się wytwarza wiedzę socjologiczną
Authors: Mazurek Małgorzata
Published: May 2021

The author investigates epistemic, methodological and ethical challenges coming out of the so-called ethnographic revisit, namely the reexamination of ‘fieldwork’ sites that underwent historical change. She explores one of the most well-known research undertakings in post-1945 Polish social sciences, a study of urban family life styles carried out by a sociologist Andrzej Siciński and his team in the late nineteen seventies. In years 2005–2006 she returned to several families who had been observed and interviewed by Siciński’s group to collect material for her own socio-historical inquiry about experiences of scarcity during and after communist era. Her last visit to Siciński’s interlocutors took place in 2013 with a more general aim to critically engage with intellectual tools (theories, fieldwork instructions and notes) that Siciński’s team employed in the study of ‘ordinary people’. The method of ethnographic revisit can serve as a valuable tool to contextualize and historicize ‘symbolic violence,’ i.e. normative, sociological and political assumptions embedded in everyday language and physical interactions, that inevitably shapes the core and each phase of sociological research. The series of revisits demonstrate the unsolved tension between the practice of sociological cataloguing and a desire to present an individual, comprehensive and historical portrait of ‘Siciński’s families’ as they have undergone the shift from the state-socialism to the neo-liberal economy and society.
Jak ułożyć puzzle? Badania nad kulturą węgierskich robotników z połowy lat siedemdziesiątych XX wieku i kilka zagadnień epistemologicznych
Authors: Gárdos Judit
Published: May 2021

The text contains information about The Voices of the 20th Century Archive and Research Group, a department created in 2009 in the Institute of Sociology of the Hungarian Academy of Sciences. The archive is a collection of data from historical—and sometimes forgotten—qualitative research. The Group attempts to complete the information and protect it from destruction. For example, in regard to research into labourers’ life styles in the 1970s, the author shows how difﬁcult it is after years to create a cohesive whole from the scattered materials. She likens the task to putting together a puzzle. She points to the possible advantages of reusing the material, as well as the limitations a contemporary researcher encounters in attempting to make sense of it.
Muzeum kolonialne, postkolonialne, transkolonialne jako model świata: przykład portugalski, brytyjski i malajski
Authors: Łukaszyk Ewa
Published: May 2021

This article attempts a comparative view of selected museums (in Coimbra, Glasgow, and Kuala Lumpur) in connection with the colonial, post-colonial, and trans-colonial history of two former empires, the British and Portuguese, as well as an area they colonized, Malaysia. The museum as a model of the world reﬂects successive cultural projects: from building awareness of the empire; through post-colonial changes; to the phase described as trans-colonial, in which the former colony begins to create its own frames of reference in the world and free itself entirely from symbolic dependence on the former colonizer. At each of these stages, exhibition institutions play an important role as a means of recreating and transferring ideas connected with identity, community, and place in the world.
Różnice i granice z perspektywy relacyjnej koncepcji kultury i teorii praktyk społecznych. Przypadek wielkomiejskiego osiedla
Authors: Nóżka Marcjanna , Smagacz-Poziemska Marta
Published: May 2021

This article is devoted to the problem of the structuring of groups living in housing settlements in large cities. Referring to the theory of social practices and the findings of empirical research, the authors show the importance of analyzing the everyday practices of housing settlements for a better understanding of the mechanisms of social production and reproduction of differences. In interpreting the research material, they show that at the level of the housing settlement and through analysis of what would seem to be ordinary activities — for instance, taking care of children, walking a dog, caring for green areas, parking, or guarding — people create, negotiate, and contest borders, reproducing and modifying more or less permanent socio-spatial arrangements. These arrangements, although they are described by the term “neighborhood,” significantly depart from the understanding of “neighborhood” in the spirit of twentieth-century sociology — as an arrangement of relations and dependence between people resulting from their nearness of residence.
Women’s Sense-making of Opportunity Structures in the Profession of Attorney in Poland
Authors: Choroszewicz Marta
Published: May 2021

The article examines the ways in which women make sense of the opportunity structures in which they operate as female attorneys in Poland. The study applies Joan Acker’s theory of gendered organization and a narrative approach to the analysis of interview data with 15 Polish female attorneys who practice law and are members of the Warsaw Chamber of the Bar. These women are pursuing their careers in a highly competitive and still male-dominated profession. The results demonstrate the continuing struggle of women to reconcile the often conflicting expectations and roles of professional and personal lives. The findings point towards four gendering processes that venture from the structure of the profession of attorney in Poland: professionally committed women are not limited by their family life; women need to invest more in activities that attract new clients; male attorneys are attributed greater authority; and women are more empathic. These processes sustain gender inequalities in the profession of attorney as they carry expectations of women to adapt to the existing professional structures in order to access more equal career opportunities. However, by making sense of the shared experiences of work-life conflict and of the feminine/masculine dichotomy, women exert agency to their claims to professional expertise.
Weakly nonlinear theory on ultrasound propagation in liquids containing many microbubbles encapsulated by visco-elastic shell
Authors: Kikuchi Yusei , Kanagawa Tetsuya
Published: May 2021

Aimed towards an application of ultrasound diagnosis using contrast agents, the dynamics of encapsulated bubbles has been theoretically investigated under the restriction of a single bubble. In this paper, we extend the theory for single bubble or some bubbles to that for many bubbles, and theoretically investigate weakly nonlinear propagation of ultrasound in an initially quiescent incompressible liquid, uniformly containing many microbubbles encapsulated by the shell as a viscoelastic body (Kelvin–Voigt model). As a result, we derived the Korteweg–de Vries–Burgers equation for a low-frequency long wave and clarified that the shell affects the advection, nonlinear, and dissipation (not dispersion) effects of ultrasound propagation. In particular, shell rigidity, surface tension, and shell viscosity increased the advection, nonlinear, and dissipation effects, respectively.

Robust Tensor Decomposition based Background/Foreground Separation in Noisy Videos and Its Applications in Additive Manufacturing
Authors: Shen Bo , Kamath Rakesh R , choo hahn , Kong Zhenyu
Published: May 2021

Background/foreground separation is one of the
most fundamental tasks in computer vision, especially for video
data. Robust PCA (RPCA) and its tensor extension, namely, Robust Tensor PCA (RTPCA), provide an effective framework for
background/foreground separation by decomposing the data into
low-rank and sparse components, which contain the background
and the foreground (moving objects), respectively. However, in
real-world applications, the video data is contaminated with
noise. For example, in metal additive manufacturing (AM), the
processed X-ray video to study melt pool dynamics is very noisy.
RPCA and RTPCA are not able to separate the background,
foreground, and noise simultaneously. As a result, the noise
will contaminate the background or the foreground or both.
There is a need to remove the noise from the background
and foreground. To achieve the three terms decomposition, a
smooth sparse Robust Tensor Decomposition (SS-RTD) model
is proposed to decompose the data into static background,
smooth foreground, and noise, respectively. Specifically, the static
background is modeled by the low-rank tucker decomposition,
the smooth foreground (moving objects) is modeled by the spatiotemporal continuity, which is enforced by the total variation
regularization, and the noise is modeled by the sparsity, which
is enforced by the L1 norm. An efficient algorithm based on
alternating direction method of multipliers (ADMM) is implemented to solve the proposed model. Extensive experiments on
both simulated and real data demonstrate that the proposed
method significantly outperforms the state-of-the-art approaches
for background/foreground separation in noisy cases.
Influence of Tire Chip Size on The Behavior of Rubberized Concrete
Authors: Roknuzzaman Md
Published: May 2021

Performance of plain concrete with partial replacement of coarse aggregate by rubber chips derived from the waste tire is taken into consideration and an attempt is made to investigate the influence of rubber size on strength, workability, and durability. Four different size ranges of tire chips such as 4.75-9.5 mm, 9.5-12.5 mm, 12.5-19 mm, and 19-25 mm are used to replace stone aggregates of corresponding sizes. A 7.5% replacement of coarse aggregate is made each time. Concrete of three different grades such as C20/25, C25/30, and C30/35 are considered. For every concrete grade, compressive strength is reduced with the addition of tire chips, but less strength loss is observed for the smaller-sized tire chips. Therefore, the best size is found to be 4.75-9.5 mm yielding a compressive strength 8.33%-18.48% (for different concrete grades) lower than that of corresponding control specimens. The workability of each mix based on slump value is found to increase with larger tire chip size. The durability inspection by acid curing reveals that 4.75-9.5 mm rubber performs best with a minimal strength reduction of 8.99%-16.38% as compared to the same specimen subjected to conventional water curing. Strength degradation is found to be more severe in the cases of the control specimen with lower strength.
Entre aproximações e rupturas: as guinadas na integração regional
Authors: Osório Luiz Felipe Brandão
Published: May 2021

A integração regional flutua no plano das ideias entre Bolívar e Monroe. Com aproximações e rupturas, a concretização da cooperação ocorre dentro das margens concedidas pela economia política liberal, o chão dos processos integracionistas. Dentro dessa dinâmica, a política externa brasileira sofreu recentemente mais uma brusca correção de rumos. A partir de 2016, a preocupação da chancelaria brasileira passa a ser desfazer o que havia sido feito pela anterior. A ruptura com o modelo vigente até então evidencia o resgate de uma postura de alinhamento automático, associativa às grandes potências ocidentais, como os Estados Unidos e sua esfera de aliados, em detrimento da autonomia e do pragmatismo de outrora. Com a nova orientação, novos foros de integração emergem, como o Fórum para o Progresso e Desenvolvimento da América do Sul (PROSUL), enquanto outros decaem, como a União de Nações Sul-Americanas (UNASUL), e outros, ainda, são redirecionados, como o Mercado Comum do Sul (Mercosul). A mudança ocorre em um contexto internacional de crise econômica e de um nítido acirramento das tensões geopolíticas em torno da disputa pela hegemonia. Em função disso, este artigo tem dois objetivos: um mais amplo, que é fundamentar a política externa brasileira de acordo com o panorama atual do capitalismo, aquele do pós-Guerra Fria, do pós-fordismo; e dentro desse universo, um mais específico, o de apontar as transformações ocorridas em termos de integração regional (grande questão do pós-1991). Por meio da ferramenta da teoria materialista do Estado pretende-se dissipar as aparências para se chegar à essência do fenômeno da política externa para integração regional no capitalismo.

Authors: Mejía Estrada Manuela , Jiménez-Segura Luz Fernanda , Soto Calderón Iván
Published: May 2021

The Barcoding was proposed motivated by the mismatch between the low number of taxonomists that contrasts with the large number of species, the method requires the construction of reference collections of DNA sequences that represent existing biodiversity. Freshwater fishes are key indicators for understanding biogeography around the world. Colombia with 1610 species of freshwater fishes is the second richest country in the world in this group. However, genetic information of the species continues to be limited, the contribution to a reference library of DNA barcodes for Colombian freshwater fishes highlights the importance of biological collections and seeks to strengthen inventories and taxonomy of such collections in future studies.

This dataset contributes to the knowledge on the DNA barcodes and occurrence records of 96 species of Freshwater fishes from Colombia. The species represented in this dataset correspond to an addition to BOLD public databases of 39 species. Forty-nine specimens were collected in Atrato bassin and 708 in Magdalena-Cauca bassin during the period of 2010 to 2020, two species (Loricariichthys brunneus and Poecilia sphenops) are considered exotic to the Atrato, Cauca and Magdalena basins and four species (Oncorhynchu mykiss, Oreochromis niloticus, Parachromis friedrichsthalii and Xiphophorus helleri) are exotic to Colombian hydrogeographic regions. All specimens are deposited in the CIUA collection at University of Antioquia and have their DNA barcodes made publicly available in the Barcode of Life Data System (BOLD) online database and the distribution dataset can be freely accessed through the Global Biodiversity Information Facility (GBIF).

Molecular cloning, expression, purification and in silico epitope prediction of cobalamin-independent methionine synthase (Mor a 2), as a novel allergen from Morus alba pollen
Authors: AKSÜT Yunus
Published: May 2021

Introduction

Morus alba (white mulberry) pollen is an aero-allergen source that can trigger allergic diseases. Cobalamin-independent methionine synthase (MetE) in M. alba pollen has been proved to be one of the major allergens for some patients living in Istanbul (Turkey). The aim of the present study was the recombinant production and identification of MetE (Mor a 2), a novel allergen from M. alba pollen. The IgE binding reactivity of rMor a 2 produced for the first time was evaluated and some structural features were investigated by in silico methods to better understand its immunogenicity.

Material and methods

The gene encoding Mor a 2 was cloned in fission yeast, Schizosaccharomyces pombe ura4-D18h- strain, using pSLF1073 vector. This is the first report of the production of recombinant pollen allergen in S. pombe. After the purification, immunoreactivity of rMor a 2 was confirmed by immunoblotting using sera of patient allergic to M. alba pollen. Besides, B-cell epitopes of rMor a 2 were predicted using various bioinformatic tools, namely Bioinformatics Predicted Antigenic Peptides, BepiPred 2.0 and Immune Epitope Database whereas T-cell epitopes were estimated using NetMHCIIpan-3.2 and NetMHCII 2.3 servers.

Results

The immunoblotting analysis yielded 11 of 11 positive reactions to rMor a 2. In silico predictions exerted seven B-cell epitopes (22-33, 384-394, 407-423, 547-553, 571-577, 671-678, 736-741) and seven T-cell epitopes (54-62, 161-170, 197-205, 347-358, 622-630, 657-665, 756-764).

Conclusions

These findings may help the use of rMor a 2 in the diagnosis and treatment of allergic diseases associated with M. alba and/or MetE.
The Sun's Role for Decadal Climate Predictability in the North Atlantic
Authors: Drews Annika , Huo Wenjuan , Matthes Katja , Kodera Kunihiko , Kruschke Tim
Published: May 2021

Abstract. Despite several studies on decadal-scale solar influence on climate, a systematic detection of solar-induced signals at the surface and the Sun's contribution to decadal climate predictability is still missing. Here, we disentangle the solar-cycle-induced climate response from internal variability and from other external forcings such as greenhouse gases. We utilize two 10-member ensemble simulations with a state-of-the-art chemistry climate model, to date a unique data set in chemistry climate modelling. We quantify the potential predictability related to the solar cycle and demonstrate that the detectability of the solar influence on surface climate depends on the magnitude of the solar cycle. Further, we show that a strong solar cycle forcing organizes and synchronizes the decadal-scale component of the North Atlantic Oscillation, the dominant mode of climate variability in the North Atlantic region.

Published: May 2021

Abstract. Fine particles were sampled from 9 November to 11 December 2016 and 22 May to 24 June 2017 as part of the Atmospheric Pollution and Human Health in
a Chinese Megacity (APHH-China) field campaigns in urban Beijing, China. Inorganic ions, trace elements, organic carbon (OC), elemental carbon (EC), and organic compounds, including
biomarkers, hopanes, polycyclic aromatic hydrocarbons (PAHs), n-alkanes, and fatty acids, were determined for source apportionment in this study. Carbonaceous components contributed
on average 47.2 % and 35.2 % of total reconstructed PM2.5 during the winter and summer campaigns, respectively. Secondary
inorganic ions (sulfate, nitrate, ammonium; SNA) accounted for 35.0 % and 45.2 % of total PM2.5 in winter and summer. Other
components including inorganic ions (K+, Na+, Cl−), geological minerals, and trace metals only contributed 13.2 %
and 12.4 % of PM2.5 during the winter and summer campaigns. Fine OC was explained by seven primary sources (industrial and residential
coal burning, biomass burning, gasoline and diesel vehicles, cooking, and vegetative detritus) based on a chemical mass balance (CMB) receptor model. It
explained an average of 75.7 % and 56.1 % of fine OC in winter and summer, respectively. Other (unexplained) OC was compared with the
secondary OC (SOC) estimated by the EC-tracer method, with correlation coefficients (R2) of 0.58 and 0.73 and slopes of 1.16 and 0.80 in
winter and summer, respectively. This suggests that the unexplained OC by the CMB model was mostly associated with SOC. PM2.5 apportioned by the CMB model
showed that the SNA and secondary organic matter were the two highest contributors to PM2.5. After these, coal combustion and biomass
burning were also significant sources of PM2.5 in winter. The CMB results were also compared with results from the positive matrix
factorization (PMF) analysis of co-located aerosol mass spectrometer (AMS) data. The CMB model was found to resolve more primary organic aerosol (OA) sources than AMS-PMF,
but the latter could apportion secondary OA sources. The AMS-PMF results for major components, such as coal combustion OC and oxidized OC, correlated
well with the results from the CMB model. However, discrepancies and poor agreements were found for other OC sources, such as biomass burning and cooking,
some of which were not identified in AMS-PMF factors.

Published: May 2021

Abstract. Data assimilation (DA) provides initial states of model
runs by combining observational information and models. Ensemble-based DA
methods that depend on the ensemble run of a model have been widely used. In
response to the development of seamless prediction based on coupled models
or even Earth system models, coupled DA is now in the mainstream of DA
development. In this paper, we focus on the technical challenges in
developing a coupled ensemble DA system, especially how to conveniently
achieve efficient interaction between the ensemble of the coupled model and
the DA methods. We first propose a new DA framework, DAFCC1
(Data Assimilation Framework based on
C-Coupler2.0, version 1), for weakly coupled ensemble DA,
which enables users to conveniently integrate a DA method into a model as a
procedure that can be directly called by the model ensemble. DAFCC1
automatically and efficiently handles data exchanges between the model
ensemble members and the DA method without global communications and does
not require users to develop extra code for implementing the data exchange
functionality. Based on DAFCC1, we then develop an example weakly coupled
ensemble DA system by combining an ensemble DA system and a regional
atmosphere–ocean–wave coupled model. This example DA system and our
evaluations demonstrate the correctness of DAFCC1 in developing a weakly
coupled ensemble DA system and the effectiveness in accelerating an offline
DA system that uses disk files as the interfaces for the data exchange
functionality.

The aim of this review is give information about choice of suitable imaging methods for TMJ diseases from past to present. In the past, conventional radiographs have often been used for TMJ imaging, but nowadays magnetic resonance imaging is the gold standard for soft tissue imaging and disc position determination. Another new technology, ultrasonography can be used for disc displacement, effusion, diagnosis of intraarticular defects. Cone beam computed tomography, it is used for the evaluation of cortical and trabecular structure of bone components of TMJ, developmental anomalies and traumatic injuries affecting TMJ, pathological changes such as osteophyte, erosion, fractures, ankylosis, glenoid fossa-condyle relationship. Nowadays, in parallel with the developing technology, a single imaging method is not used for TMJ imaging and evaluation is performed with several imaging methods. Imaging methods should be selected by evaluating the factors such as radiation dose, contribution to diagnosis and treatment plan, easy applicability.

Este artigo tem como objetivo analisar a formação de antagonismos discursivos nas hashtags #bolsolão e #marqueteirosdojair, no contexto polarizado das Eleições de 2018 no Brasil. Em contribuição aos desafios teóricometodológicos da Sociologia Digital, partimos de uma abordagem interdisciplinar, articulando a Teoria do Discurso de Ernesto Laclau e Chantal Mouffe à Análise de Redes Sociais na internet. A partir disso, coletamos um total de 26.548 tweets da API do Twitter através do software NodeXL Pro. Assim, investigamos as duas hashtags selecionadas através de uma análise de contingência, conforme as métricas da modularidade e do grau de intermediação. Desse modo, verificamos quais os sentidos encadeados na formação das duas hashtags, descrevendo como estão articulados segundo as lógicas de equivalência e de diferença. Concluímos que a nossa proposta teórico-metodológica permite observar a polarização política como um fenômeno dinâmico, contingente e contraditório no social, associado à emergência de antagonismos discursivos.

Background: Malaria is a well-recognized parasitic disease and a serious public health problem worldwide, particularly in tropical and subtropical areas. Objectives: This study was conducted to investigate the antimalarial properties of extracts with different polarities from the various parts of Ecballium elaterium (L.) Rich. (or wild cucumber) as a perennial herbaceous plant growing in Gilan and Azerbaijan provinces of Iran. Methods: The air-dried and powdered fruits, seeds, and roots of E. elaterium were extracted using three solvents with different polarities, n-Hexane (n-Hex), dichloromethane (DCM), and methanol (MeOH). The MeOH extract of roots was subjected to fractionalizing by a C18 Sep-Pak cartridge. All extracts and fractions with different polarities were assessed for their antimalarial activity using the cell-free beta-hematin formation test, and the structural groups of the fractions were identified by Thin-Layer Chromatography (TLC). Results: According to our results, the MeOH extracts of the plant’s roots presented considerable antimalarial effects with an IC50 value of 0.124 ± 0.0002 mg/mL. Bioactivity-guided fractionation of root MeOH extract by solid phase extraction (SPE) afforded six fractions. The 20% fraction showed the most potent antimalarial effect with an IC50 value of 0.167 ± 0.002 mg/mL. Moreover, the three fractions of 80%, 60%, and 100% methanol/water demonstrated considerable antimalarial activities. Phytochemical analysis of potent fractions of E. elaterium suggested the presence of flavonoids in 20% and 60% fractions and flavonoids and triterpenoids in 80% and 100% fractions. Conclusions: According to our primary phytochemical investigation on the six SPE fractions, it is recommended to purify the active constituents of the most effective fractions and investigate their biological effects in animal models.

AbstractThe primary objective of this study was to analyze the direct explanatory power of social identity, schooling, and age on self-esteem, as well as the indirect effects of those variables (through the mediating variable self-esteem) on hope. A non-probabilistic sample composed of 657 persons from southern Nuevo Leon was recruited (mean age = 39.75 years; SD = 16.96). Structural equation modeling was used to analyze the effects, both direct and indirect, of the independent variables upon the dependent variables. With regard to hope, the model yields an explained variance of 37% (d ≥ 26% = large effect size) and shows well goodness-of-fit indices: χ2 / df = 2.618, GFI = .997, AFGI = .978, CFI = .995, NNFI = .995, NFI = .992, RMSEA = .048 (IC90%, .001, .100), and SRMR = .017. It is concluded that social identity, together with some contextual variables of a personal nature (for instance, age and schooling) is probably very important to explain the levels of self-esteem and hopeResumenEl objetivo primario de este estudio fue analizar el poder explicativo de las variables identidad social, escolaridad y edad, directamente sobre la autoestima y los efectos indirectos de las tres primeras, a través de la autoestima, sobre la esperanza. Se realizó el estudio en una muestra no probabilística de 657 hombres y mujeres, con edad promedio de 39.75 años (DE = 16.96). Se usó modelamiento de ecuaciones estructurales para analizar los efectos, tanto directos como indirectos, de las variables independientes sobre las dependientes. Se encuentra que el modelo tiene una varianza explicada del 37% (d = ≥ 26% = tamaño del efecto grande) en esperanza, con buenos indicadores de bondad de ajuste: χ2/gl = 2.618; GFI = .997; AFGI = .978; CFI = .995; NNFI = .995; NFI = .992; RMSEA = .048 (IC90%, .000, .100), SRMR = .017. Se concluye que probablemente la identidad social, junto con algunas variables contextuales de tipo personal, como la edad y la escolaridad, es prioritaria para explicar la existencia de la autoestima y de la esperanza.

The principles of designing sandwich panels for slamming loads include selecting the correct core materials and understanding the fundamental loading differences between static uniformly distributed pressure loads and slamming induced pressure pulses. This paper will discuss the two issues in detail.

The results demonstrate that the testing method used for characterisation of core materials can have a significant effect on the shear strength obtained, and that slam loaded panels are subjected to higher shear loads relative to bending than is the case for uniform pressure loaded panels. The combination of these factors results in significant performance advantages for high-elongation foam cores in slam loaded hull panels.
La regulación sobre la conservación de datos en el sector de las comunicaciones electrónicas o telecomunicaciones: estado de la cuestión
Authors: Polo Roca Andoni
Published: May 2021

La Directiva 2006/24/CE del Parlamento Europeo y del Consejo, de 15 de marzo de 2006, sobre conservación de datos estableció la obligación de los operadores de telecomunicaciones de conservación generalizada e indiferenciada de los datos relativos a las comunicaciones electrónicas (telefonía fija, móvil o internet) con fines de investigación, detección y enjuiciamiento de delitos graves. El TJUE, sin embargo, hizo tambalear las bases de dicha regulación con los casos Digital RightsIreland y Seitlinger y otros (2014) y Tele2 Sverige y Watson y otros (2016), en los que declaró contraria al Derecho de la Unión la conservación de datos en los términos de la Directiva de 2006. Por su parte, en el Derecho español, fue la Ley 25/2007, de 18 de octubre, de conservación de datos relativos a las comunicaciones electrónicas y a las redes públicas de comunicaciones la que hizo la transposición de la Directiva de Conservación de Datos (2006), si bien, a la luz de la doctrina del TJUE, su aplicación podría ser cuestionada (al igual que las demás legislaciones nacionales que la traspusieron). No obstante, lejos de ser una cuestión pacífica, se han venido manteniendo posiciones muy distintas por parte del Tribunal Supremo en sus resoluciones o de la doctrina. A ello se le añaden, además, los pronunciamientos posteriores del TJUE, en especial el caso La Quadrature du Net y otros contra Premier ministre y otros (2020), en los que el TJUE ha ido sentando las bases de la conservación de datos en el ámbito de las comunicaciones electrónicas o telecomunicaciones.

The evolution of bipedalism and reduced reliance on arboreality in hominins resulted in larger lower limb joints relative to the joints of the upper limb. The pattern and timing of this transition, however, remains unresolved. Here, we find the limb joint proportions of Australopithecus afarensis, Homo erectus, and Homo naledi to resemble those of modern humans, whereas those of A. africanus, Australopithecus sediba, Paranthropus robustus, Paranthropus boisei, Homo habilis, and Homo floresiensis are more ape-like. The homology of limb joint proportions in A. afarensis and modern humans can only be explained by a series of evolutionary reversals irrespective of differing phylogenetic hypotheses. Thus, the independent evolution of modern human-like limb joint proportions in A. afarensis is a more parsimonious explanation. Overall, these results support an emerging perspective in hominin paleobiology that A. afarensis was the most terrestrially adapted australopith despite the importance of arboreality throughout much of early hominin evolution.
