Muito além do Arco-íris: homossexualidade(s) e diversidade sexual em práticas discursivas em torno de uma Igreja Inclusiva da cidade do Recife-PE
Authors: Silva Silas Veloso de Paula , Almeida Júllia Alves de , Dias Priscylla Karollyne Gomes 
Published: October 2021

Este artigo é resultado de uma pesquisa qualitativa - de caráter exploratório - em desenvolvimento, que que busca compreender os “embates hegemônicos” entre campos discursivos de igrejas inclusivas e igrejas tradicionais em torno das questões de gênero e sexualidade. A partir da Teoria do Discurso em diálogo com a Análise do Discurso, pretende-se analisar quais são as práticas discursivas que as igrejas inclusivas reproduzem e transferem de igrejas tradicionais em torno da relação entre religião cristã e diversidade sexual e de gênero. Para isso, foram aplicadas entrevistas semi-estruturadas com membros/as de uma igreja inclusiva na cidade do Recife-PE. Conclui-se apontando que as lógicas sociais da transferência, da distinção, e da restituição cristã constituem ethos cristão, afirmativo e convertido que, por sua vez, se interrelacionam na configuração conflitiva de práticas sociais e discursivas dinamizadas pela disputa política e religiosa.
Direitos humanos, gênero e patriarcado: o estupro como ato-violação
Authors: Lima Luana , Boeira Laura dos Santos 
Published: October 2021

As sociedades contemporâneas parecem ter como marca comum os atravessamentos das estruturas de gênero delineadas por estruturas de poder. O estupro evidencia, sob a égide do patriarcado, diversas facetas do uso abusivo dos corpos femininos e feminilizados. Objetiva-se debater a temática do estupro de corpos femininos através das intersecções entre gênero e direitos humanos. Nesse sentido, foi realizada uma pesquisa crítica de revisão de literatura alicerçado nos saberes supracitados. No ato-violação do estupro, a masculinidade e o poder se entrelaçam. O uso do aparelhamento sexual parece responder às necessidades não sexuais; são atos orientados por condutas moralistas, de dominação e posse. O corpo da mulher é expropriado no estupro cruento como formas de: 1) punição contra uma mulher genérica que saiu da sua posição de subordinada dentro de um sistema de relações; 2) como agressão ou afronta contra um homem também genérico; 3) como uma demonstração de virilidade para uma comunidade de pares. No contexto intrafamiliar, como direito por quem, como provedor, exige pagamento do débito das mulheres do seu grupo. No âmbito legal, parece haver uma distinção signficativa entre o estupro cruento – mais facilmente reconhecido pela sociedade como crime por se tratar de um autor desconhecido - e o estupro por parceiro íntimo ou familiar, onde encontramos discursos que mais protegem a família enquanto instituição, do que a mulher como sujeito de direitos. A influência do estatuto do autor e, especialmente da vítima, a relação entre eles, o histórico de moralidade e sexualidade determinam o acesso ou não aos procedimentos de direito, como a punibilidade, abortamento, etc. No âmbito do acesso à saúde, o aborto por estupro permanece tendo estatuto de crime, a despeito das legislações, com a punição sendo aplicada informalmente pelos profissionais de saúde, mediada por seus preceitos morais. Destarte, o despreparo e falta de capacitação das equipes, a discriminação, o estigma, a moralidade, etc., desembocam na reprodução da violência contra à mulher, numa máquina que vai do lar ao Estado, gerida pelo patriarcado.

AbstractThe production of clean fuels and chemicals from waste feedstocks is an appealing approach towards creating a circular economy. However, waste photoreforming commonly employs particulate photocatalysts, which display low product yields, selectivity, and reusability. Here, a perovskite‐based photoelectrochemical (PEC) device is reported, which produces H2 fuel and simultaneously reforms waste substrates. A novel Cu30Pd70 oxidation catalyst is integrated in the PEC device to generate value‐added products using simulated solar light, achieving 60–90% product selectivity and ≈70–130 µmol cm−2 h−1 product formation rates, which corresponds to 102–104 times higher activity than conventional photoreforming systems. The single‐light absorber device offers versatility in terms of substrate scope, sustaining unassisted photocurrents of 4–9 mA cm−2 for plastic, biomass, and glycerol conversion, in either a two‐compartment or integrated “artificial leaf” configuration. These configurations enable an effective reforming of non‐transparent waste streams and facile device retrieval from the reaction mixture. Accordingly, the presented PEC platform provides a proof‐of‐concept alternative towards photoreforming, approaching more closely the performance and versatility required for commercially viable waste utilization.

AbstractA smart face mask that can conveniently monitor breath information is beneficial for maintaining personal health and preventing the spread of diseases. However, some challenges still need to be addressed before such devices can be of practical use. One key challenge is to develop a pressure sensor that is easily triggered by low pressure and has excellent stability as well as electrical and mechanical properties. In this study, a wireless smart face mask is designed by integrating an ultrathin self‐powered pressure sensor and a compact readout circuit with a normal face mask. The pressure sensor is the thinnest (totally compressed thickness of ≈5.5 µm) and lightest (total weight of ≈4.5 mg) electrostatic pressure sensor capable of achieving a peak open‐circuit voltage of up to ≈10 V when stimulated by airflow, which endows the sensor with the advantage of readout circuit miniaturization and makes the breath‐monitoring system portable and wearable. To demonstrate the capabilities of the smart face mask, it is used to wirelessly measure and analyze the various breath conditions of multiple testers.
Method to concurrently measure local gas and solid holdups visually with higher precision in circulating fluidized bed

Published: October 2021

AbstractSimultaneous and visual measurements of local gas and solid phase holdups with high‐precision in a gas–liquid–solid circulating fluidized bed is of great importance for the design and scale‐up of such a reactor. However, such measuring techniques are still limited due to the difficulty of discrete phase identification of gas bubble and solid particle phases in the complex three‐phase flow. Immersed telecentric camera method developed based on the digital image processing is such a measuring technique, but its measuring precision is to be improved due to the existing three problems in the depth‐of‐field particle extraction, reconstruction of dim bubbles, and counting of overlapping particle clusters. This work has solved these problems by developing corresponding algorithms and the relative errors of measured solid holdup and gas holdup are as low as 0.3% and 1.0%, respectively.

Published: October 2021

AbstractThe analysis of process and equipment operational data in chemical engineering regularly requires a high level of expert knowledge. This work presents a Machine Learning‐based approach to evaluate and interpret process data to support robust operation of a thermosiphon reboiler. By applying an outlier detection, potentially interesting and unstable operating conditions can be identified quickly. A multidimensional regression allows to forecast the circulating mass flow. The results obtained fit well into the current state of research and manual evaluation of thermosiphon reboilers.
Quality ensured non‐orthogonal multiple access based downlink scalable video coding multicasting over cognitive radio network
Authors: Dey Sudipta , Misra Iti Saha 
Published: October 2021

AbstractThe combination of the cognitive radio network (CRN) and non‐orthogonal multiple access (NOMA) technologies for scalable video coding (SVC) can be considered as a promising approach for quality‐driven video transmission over a fifth‐generation (5G) network. Advanced techniques such as efficient channel allocation, advanced sensing strategy, and optimum power allocation can combinedly improve the overall system performance. In this context, we propose an intergroup content‐aware proportionate channel allocation policy, sensing time optimization strategy and quality of service (QoS) ensured intragroup power allocation scheme for downlink SVC multicasting over CRN using NOMA technology to enhance the quality of experience (QoE) of secondary users (SUs). We propose an optimum power allocation strategy for different NOMA layers to maximize the weighted sum rate of different SVC groups ensuring the individual QoS requirements. Although the power allocation problem seems to be nonconvex, however, it can be transformed into a convex function under some specific conditions which are discussed in this article. Extensive simulation reveals that our proposed power allocation scheme for NOMA with QoS constraint outperforms the other two conventional schemes, that is, NOMA fixed power allocation and NOMA without QoS constraint in terms of average weighted sum rate and average QoE of SUs.

AbstractBACKGROUNDIt is of great significance industrially to find cheap materials as low‐temperature selective catalytic reduction (SCR) catalyst support. Pyrolyzed rice husk char (RC) is not only cheap, but also has the characteristics of high porosity, large SSA and good adsorption. Therefore, there is emerging interest in RC as an SCR support. The present contribution is a comparative study of low‐temperature SCR manganese–cerium (MnCe) catalysts based on RC activated by potassium hydroxide (KOH) and phosphoric acid (H3PO4), revealing the different mechanisms of improvement in catalytic performance.RESULTSMn‐Ce/RCK (catalyst of MnCe loaded on KOH activated RC) has a wider activity temperature window in the range 120–260 °C, while Mn‐Ce/RCP (catalyst of MnCe loaded on H3PO4 activated RC) can reach the highest NO conversion of 97% at 240 °C.CONCLUSIONSN2 adsorption–desorption, Fourier transform infrared (FTIR), X‐ray diffraction (XRD), NH3‐temperature programmed desorption (TPD) and X‐ray photoelectron spectroscopy (XPS) were used to characterize and analyze their catalytic performance. The N2 adsorption–desorption and NH3‐TPD showed that Mn‐Ce/RCK has a larger SSA and more acid sites than those of Mn‐Ce/RC and Mn‐Ce/RCP. XRD indicated that Mn‐Ce/RCP has a better dispersion than that of Mn‐Ce/RCK. FTIR showed that Mn‐Ce/RCP had more oxygen (O)‐containing functional groups. The XPS revealed that Mn‐Ce/RCP has higher ratios of Mn4+, Ce3+ and Oβ. © 2021 Society of Chemical Industry (SCI).
In Vitro Validation of Regional Circumferential Strain Assessment in a Phantom Aortic Model Using Cine Displacement Encoding With Stimulated Echoes MRI
Authors: Wilson John S. , Islam Muhammad , Oshinski John N. 
Published: October 2021

BackgroundA novel application of cine Displacement ENcoding with Stimulated Echoes Magnetic Resonance Imaging (DENSE MRI) has recently been described to assess regional heterogeneities in circumferential strain around the aortic wall in vivo; however, validation is first required for successful clinical translation.PurposeTo validate the quantification of regional circumferential strain around the wall of an aortic phantom using DENSE MRI.Study TypeIn vitro phantom study.PopulationThree polyvinyl alcohol aortic phantoms with eight axially oriented nitinol wires embedded evenly around the walls.Field Strength/Sequence3 T; gradient‐echo aortic DENSE MRI with spiral cine readout, gradient‐echo phase‐contrast MRI (PCMR) with Cartesian cine readout.AssessmentPhantoms were connected to a pulsatile flow loop and peak DENSE‐derived regional circumferential Green strains at 16 equally spaced sectors around the wall were assessed according to previously published algorithms. “True” regional circumferential strains were calculated by manually tracking displacements of the nitinol wires by two independent observers. Normalized circumferential strains (NCS) were calculated by dividing regional strains by the mean strain. Finally, DENSE‐derived regional strain was corrected by multiplying regional DENSE NCS by the mean strain calculated from the diameter change on the PCMR.Statistical TestsOne‐sample t‐test, Paired‐sample t‐test, and analysis of variance with Bonferroni correction, coefficient of variation (CoV), Bland–Altman analysis; P < 0.05 was considered statistically significant.ResultsAortic DENSE MRI significantly overestimated circumferential strain compared to the wire‐tracking method (mean difference and SD 0.030 ± 0.014, CoV 0.31). However, NCS demonstrated good agreement between DENSE and wire‐tracking data (mean difference 0.000 ± 0.172, CoV 0.15). After correcting the DENSE‐derived regional strain, the mean difference in regional circumferential strain between DENSE and wire‐tracking was significantly reduced to 0.006 ± 0.008, and the CoV was reduced to 0.18.Data ConclusionFor aortic phantoms with mild spatial heterogeneity in circumferential strain, the previously published aortic DENSE MRI technique successfully assessed the regional NCS distribution but overestimated the mean strain. This overestimation is correctable by computing a more accurate mean circumferential strain using a separate cine scan.Level of Evidence2Technical EfficacyStage 2
Enhanced impact of early‐summer tropical eastern Pacific sea surface temperature on the July–August precipitation over North China after the late 1970s

Published: October 2021

AbstractThis study identified an enhanced interannual relationship between early‐summer (June–July) tropical eastern Pacific (TEP) sea surface temperature (SST) and subsequent mid‐summer (July–August) precipitation in North China (NC) since the late 1970s. For 1951–1972, the relationship between early‐summer TEP SST and mid‐summer NC precipitation were statistically insignificant. In contrast, for 1977–2018, they were positively significant. Since the late 1970s, the early‐summer negative TEP SST anomaly was generally followed by a significant anomalous anticyclone over the Korean Peninsula and its environs; that facilitated anomalous southerly winds over NC, conveying more moisture from the North Pacific, leading more precipitation over NC. Further studies show that the enhanced relationship between early‐summer TEP SST and tropical Indian Ocean to WNP SST are suggested to be responsible for significantly anticyclonic anomalies over WNP after the late 1970s.

Published: October 2021

Societal Impact StatementEastern Africa is currently infested with dodders—highly invasive vines that threaten agriculture and biodiversity. We describe historical and ecological factors that have potentially shaped dodder invasion in this region. Our results reveal high levels of genetic diversity within dodder populations, which could enhance their ability to colonize new niches. Further, we identify two main population clusters in eastern and western Kenya, a pattern that is mirrored in an established invader (Cuscuta campestris) and a recent introduction (C. reflexa). Immediate control strategies are needed to limit deliberate or inadvertent seed/vine dispersal, eradicate existing populations, and monitor influx of propagules.Summary

Invasion by dodder (Cuscuta spp.), holo‐parasitic plants of the Convolvulaceae family, has recently surged in Eastern Africa. Particularly, colonization by two species, Cuscuta campestris and Cuscuta reflexa that have a broad host range and rapid invasiveness, has escalated. We examined the first assessment of genetic diversity of these invasive species in Kenya to inform subsequent management practices.
A comparative phylogeographic analysis, based on chloroplast and nuclear ribosomal DNA, was performed to determine genetic diversities, population structure, and isolation of C. campestris and C. reflexa in Kenya.
Results reveal high genetic variation in both species within populations across localities. C. campestris had more haplotypes and higher gene diversity (P = .0001) and heterozygosity (P = .004) than C. reflexa. Both species were geographically separated, evidenced by two distinct lineages that mostly corresponded to localities east and west of Kenya. Correlation between genetic and geographic distances revealed evidence of isolation by distance (IBD).
We attribute these genetic variation patterns to establishment via similar invasion routes for the studied Cuscuta spp. and suggest that Cuscuta invasion in Kenya is in the early stages of establishment. Rapid eradication is urgently needed to prevent shifts to economically important hosts, which would have devastating impacts. We recommend (i) development of targeted efforts to curb new introductions to limit the potential for genetic variability and adaptation, (ii) prevention of seed and vine dispersal from current incursions, and (iii) complete eradication of existing populations where this is feasible.

AbstractBackground and purposeLow back pain (LBP)‐related misbeliefs are known to be among risk factors for LBP chronification and for persistence of chronic pain. The main objective of this study was to investigate the current LBP‐related beliefs in the general population in Belgium, considering the fact that the last survey in Belgium about the topic was conducted more than 15 years ago.MethodsA cross‐sectional study design was used. Belgian adults (>17 years old) were recruited in the three regions of the country by means of non‐probabilistic recruitment methods. Participants were invited to fill in a battery of questionnaires including demographic questions as well as questions about their LBP history and the LBP Beliefs Questionnaire (LBPBQ).ResultsA total of 3724 individuals participated in the study. The LBPBQ scores indicated several LBP‐related misbeliefs. About 15%–25% of participants still think that imaging tests can always identify the cause of pain and that bed rest is the mainstay of therapy. The majority of the participants think that “unnecessary” movements should be avoided when having LBP (58% of the respondents), and that they should “take it easy” until the pain goes away (69%). Most respondents also had maladaptive/wrong expectations, for example, a systematic worsening with time (65%) and a need for surgery in case of disc herniation (54%).ConclusionsThe present study suggests that in 2020 several LBP‐related misbeliefs are still current in Belgium, particularly regarding the vulnerability of the spine. Therefore, further efforts to improve LBP‐related beliefs/knowledge in the general population are necessary.
Personal Data Protection in the Context of the Act on the National Cybersecurity System
Authors: Nowikowska Monika 
Published: October 2021

AbstractThe dynamic development of technology has led to significant changes in the concept of cyberspace. Currently, it is primarily a virtual space in which we communicate with each other using computers, phones and tablets connected by a network. Cyberspace protection has now become one of the most frequently discussed security-related topics. At a time when information systems allow the collection of huge amounts of information, supervision over data security is one of the key challenges of each country and individual network users. This article describes the principles of personal data protection by national CSIRTs, which are responsible for handling and responding to computer security incidents.
The Authorities Competent for Cybersecurity
Authors: Brzostek Agnieszka 
Published: October 2021

AbstractAuthorities competent for cybersecurity matters are indicated in Article 41 of the NCSA. The legislator created a catalogue of organs, at the same time specifying the scope of their properties. The legislator, while creating the catalogue of competent authorities, indicated among them ministers managing government administration departments. The Polish Financial Supervision Authority is an exception.Various legal doubts arise in analysing the legal status of authorities and the scope of their tasks. First of all, the authorities competent for cybersecurity were explicitly indicated as an element of the National Cybersecurity System, but their exact indication as public entities was missing.Secondly, attention should be paid to the overlapping of competences of authorities competent for cybersecurity with the competent authorities in the field of crisis management.The specified catalogue of the scope of tasks of the organs was limited to listing their individual tasks. In the implementation of tasks, public administration bodies use their imperious forms of activity.It is also worth noting that the competent authorities consult and cooperate with relevant national law enforcement and national data protection authorities. The presence of various legal problems and issues was the motivation behind this article.
Role of the Minister Competent for Computerisation in the Cybersecurity System
Authors: Chałubińska-Jentkiewicz Katarzyna 
Published: October 2021

AbstractA public administration authority, as a functional unit of public administration, is responsible for the implementation and quality of public services. The areas of competence of administrative authorities often refer to a specific field. This is also the case with computerisation. The processes it involves are closely related to innovation, new technologies and science. Computerisation has formed the substantive area of activities of various ministries. The minister competent for computerisation performs a range of organisational and reporting tasks and is responsible for the monitoring the implementation of the Cybersecurity Strategy of the Republic of Poland and the performance of action plans for its implementation. The minister prepares annual reports on significant incidents reported by operators of essential services and substantial incidents reported by digital service providers, being responsible for monitoring the strategic dimension of cybersecurity.
