DAMRN: Deep attention mechanism residual network for deepfake audio detection using cepstral coefficient features
Authors: Zhou Feng , Yang Haitao , Yan Xiai , Xiong Yingzhuo
Published: June 2024

In order to further curb the misuse of Deepfake audio technology, we proposed deep attention mechanism residual network (DAMRN) that can effectively detect forged audio. The network exhibits stable operation, low risk of gradient disappearance and gradient explosion, and high detection accuracy. The structure of proposed network mainly involves the following contents: Firstly, a data balancing strategy is adopted in the front end of the network so that the ratio of positive and negative samples in the data maintained proportional balance, which improves the network performance and reduces the overfitting phenomenon. This strategy has been effectively proven by the experiments in this article. Secondly, we compare the accuracy rates of different depths among the network models for Deepfake audio detection (DFAD), and select the network that best suits the depth of this article. Finally, we introduce an effective attention mechanism in the network structure appropriately to increase the network's sensitivity to forged speech artifact information. By obtaining the artifact information of the Deepfake audio, the network model can learn more falsification frequency features that can effectively distinguish between spoofed and bonafide audio, and the accuracy has been improved to 99.81%, with the EER reduced to 0.69%, compared to the baseline system. Experiments are conducted using three acoustic features (MFCC, LFCC, GFCC) extracted from two mainstream datasets (ASVspoof2019LA, ASVspoof2021DF) respectively, and the results show that the best EER value of the method proposed in this paper is 0.32%, which is a better performance compared with other mainstream models.
Investigation the DNA binding ability of CIA5 in Chlamydomonas reinhardtii
Authors: Chen Bo , Spalding Martin H.
Published: May 2024

CIA5 is a zinc-finger containing transcription regulator reported to be a master regulator of the critically important, inducible CO2-concentrating mechanism of the model, unicellular green alga, Chlamydomonas. Although mutants in the CIA5 gene facilitated identification of CIA5 more than two decades ago, we still know little about the detailed function of this important protein. Here we report the first successful over-expression of full length CIA5 proteins in E. coli, confirmed by SDS-PAGE and Western immunoblots. We also used these purified, full length CIA5 proteins to identify potential specific DNA-binding sequences using random binding site selection (RBSS), which was confirmed using a gel mobility shift assay (GMSA) to demonstrate highly specific protein-DNA interaction with purified, full-length CIA5. In addition, we identified a 9-bp GC rich (GGGGCGGGG) motif from the promoters of CIA5 dependent genes, and demonstrated using GMSA that promoter fragments containing this candidate motif from three CIA5-dependent genes also showed highly specific protein-DNA interaction with CIA5, although the GMSA interactions were somewhat weaker than with the RBSS-identified sequence. Nonetheless, this work clearly provides the first direct evidence that CIA5 can bind specific DNA sequences in vitro and thus opens the way for more extensive in vivo experiments to determine whether the specific DNA-binding of CIA5 has any biological relevance in vivo.

Published: June 2024

Adult neurogenesis may help overcome Alzheimer’s disease; however, knowledge concerning neurogenic markers in the human brain remains limited. Herein, we compared the hippocampal single-nucleus transcriptome to other cortical regions to verify the neurogenic markers exclusive to the dentate gyrus. We analyzed 26,189 of the 40,691 nuclei initially extracted from four human brains within 16 hours of death. Analyses were performed after clustering and annotation to elucidate differential expression, gene ontology, pseudo-time trajectory, and intercellular communication. Immature markers, including doublecortin (DCX), CALB2, NES, SOX2, PAX6, DPYSL3, and TUBB3, were widely expressed in both the hippocampus and the prefrontal cortex, with higher expression levels in the prefrontal cortex. DCX appears to not only play a role in neurogenesis but also in the neuroprotective or restorative pathways. This study revealed that neurogenic markers are not definitive indicators of adult neurogenesis as their cellular makeup is more nuanced than previously thought.

Published: June 2024

Background
In studies with small sample sizes, the use of nonparametric methods is generally recommended for statistical analysis. However, various studies continue to employ parametric analysis without verifying the assumption of a normal distribution.
Objectives
To assess the current utilization of parametric and nonparametric methods for primary outcomes, as well as the reporting of normality assumptions, in phase 3 clinical trials with small sample sizes.
Methods
All phase 3 trials registered on ClinicalTrials.gov until September 12, 2023, were collected. After undergoing a two-step selection process, only publications with a sample size per group of less than 30, involving two or more groups, and specifying the statistical methods used to compare the means or medians of primary outcomes between groups were selected. Statistical methods were categorized as nonparametric, parametric, and either parametric or nonparametric. The reporting of normality assumptions was also evaluated.
Results
A total of 317 studies were assessed in this study. Among these studies, 164 (51.7%) studies conducted parametric analysis, and 111 (35.0%) studies employed nonparametric analysis; however, 42 (13.2%) studies conducted parametric or nonparametric analysis without specifying which method was used. In addition, 63.1% of the total studies did not report normality assumptions. Specifically, within the subset of studies with parametric analysis, 70.1% of studies did not report normality assumptions.
Conclusions
This research demonstrated that most studies with small sample sizes employed parametric analysis without reporting normality assumptions. The findings emphasize the need for increased awareness of and compliance with statistical principles in the analysis of phase 3 clinical trials with limited sample sizes.
The causality between chronic rhinosinusitis and inflammatory bowel disease: a bi-directional two-sample Mendelian randomization analysis
Authors: Huang Junyu , Liu Zan
Published: June 2024

Background: Prior studies have shown that chronic rhinosinusitis(CRS) was associated with inflammatory bowel disease(IBD) consisted of Crohn's disease (CD) and ulcerative colitis (UC). However, the causality needs to be further verified. We performed a bi-directional two-sample Mendelian randomization (MR) analysis to investigate the causal effect between CRS and IBD.
Methods: We obtained CRS database from the IEU Open GWAS project and IBD database from FinnGen. Inverse-variance weighted (IVW) method was used as the primary statistical method, while weighted median and MR-Egger methods were used to examine the robustness of our results. Furthermore, Cochran’s Q test, MR-Egger intercept, MR-PRESSO and leave-one-out methods were used to examine pleiotropy and heterogeneity.
Results:IVW method revealed that CRS was associated with an increased risk of UC(OR=3.44E+08, 95% CI=3.01-3.94+16, p=0.038). Reverse MR analysis revealed that IBD was associated with a decreased risk of CRS(OR=0.999, 95% CI=0.998-1.000, p=0.020).
Conclusion: Our findings revealed that CRS was associated with an increased risk of UC, while IBD was associated with a decreased risk of CRS and the effect is mild. We suggested that clinicians should pay attention to the intestinal symptoms in CRS patients and a timely screening colonoscopy to detect early lesions.
Non-contact concentration measurement of high-viscosity aqueous solutions
Authors: Iwasaki Kazuma , Fujii Sho , Kimura Tsuyoshi , Yamamoto Masaya , Tanabe Tadao
Published: June 2024

To evaluate the concentration dependence of THz spectra, we used THz time-domain spectroscopy (THz-TDS) to measure the transmittance of aqueous solution samples of ethylene glycol and glycerol at room temperature in the frequency range of 0.4 THz and below, and analyzed the spectra in the region below 0.2 THz where water absorption is low. The results showed that for both ethylene glycol and glycerol samples, the interference spectral shape based on the change in dielectric constant changed as the liquid concentration was varied. Peak separation was performed on the peaks of the obtained spectra, and a comparison of the change in peak position with concentration showed a shift in the peak at 0.17 THz for both samples. The shifts between 60% and 100% reagent concentrations are approximately 0.003 THz for ethylene glycol and 0.006 THz for glycerol. The shift for glycerol, which has three hydroxy groups (OH groups) and thus has greater intermolecular interactions, is twice that of ethylene glycol. Glycerol showed a linear relationship between concentration change and peak shift. These results indicate that non-contact concentration measurement using terahertz waves is possible and that higher viscosity is more suitable as a measurement target.

Published: June 2024

This study investigates the Mihoub region within the Blida Mountains of the Tellian Atlas(Abacha et al., 2014), an area prone to earthquakes due to the Africa-Eurasia plate convergence since the Late Cretaceous. We present both the 1910 Aumale earthquake (Ms 6.6 and I0=VIII) and the 2016 seismic sequence (Mw 5.3). Using local seismic tomography (LET) with Local Tomography Software in its twelfth version (LOTOS 12), we analyze velocity anomaly patterns and their correlation with subsurface structures in the Mihoub area. Our dataset includes 503 well-localized aftershocks from the 2016 seismic sequence. Results show consistent patterns, with positive anomalies associated with rigid block structures and negative anomalies associated with basins, recent formations, and tectonic structures. In particular, a NE-SW corridor of low-velocity anomalies aligns with Miocene and Oligocene formations. Mainshock and aftershock epicenters from the 2016 sequence align with the boundary between low and high-velocity anomalies, indicating the Mihoub Fault zone. Fault depth analysis suggests a maximum depth of 8 km, consistent with previous research. Vertical sections confirm similar azimuths and dips of fault segments involved in the 2016 and 2014 mainshocks. This study provides valuable insights into velocity anomaly patterns and their relationship to fault structures, enhancing the understanding of fault systems and seismic hazards in the Mihoub area.
Resource misallocation and market inefficiency: Investigating the healthcare sector when considering undesirable output
Authors: Shen Zhiyang , Baležentis Tomas
Published: June 2024

Numerous scholars have integrated the consideration of undesirable (bad) outputs into data envelopment analysis methods for evaluating environmental efficiency or productivity. However, there has been limited application of this approach to assess the operational performance of hospitals that involves bad outputs. This study specifically focuses on the mortality of hospital patients as a bad output, and the underlying assumption is that patients with severe medical conditions tend to choose higher-tier hospitals with better medical conditions for treatment. These critically ill patients may inherently exhibit elevated mortality rates. Moreover, when a surge of such patients inundates a hospital, constraints in equipment, staffing levels, and quality may impede the continuity of medical care. Essentially, insufficient resources to attend to patients can result in an upswing in the number of deaths. Therefore, utilizing provincial-level hospital data in China, this paper analyzes how resource misallocation affects patient mortality. Furthermore, it explores potential strategies for optimizing resources in order to enhance the overall efficiency and effectiveness of healthcare delivery.

Authors: Fang Huicheng , Yu Wei , Gao Boyan , Niu Yuge , Yu Liangli
Published: June 2024

The composited hydrogels derived from natural materials are getting attention in the field of cultured meat due to their advantages of biocompatibility and degradability as cell scaffolds. In this work, two edible cross-linking agents, transglutaminase (TGase) and/or calcium ions, were successfully used to cross-link soy protein isolated (SPI) and soy dietary fiber (SDF) to fabricate different scaffolds. The prepared scaffolds were characterized by structural, hydration, rheological and mechanical analysis. The double cross-linked scaffolds exhibited highest compressive moduli compared to the single cross-linked scaffolds and had an excellent liquid absorbing ability up to 309.45%, while its porosity was as high as 72.66%. In addition, NIH 3T3 cells were used to evaluate the biocompatibility of the scaffolds in vitro. The double cross-linked scaffolds could promote the expression of differentiation-related genes and were beneficial for cell adhesion and proliferation. In conclusion, present research provides a new approach to prepare cell scaffolds using soybean resources, which could be used in cultured meat applications.
The Membership in the World Trade Organization and Trade Policy Space in Developing Countries
Authors: GNANGNON Sena Kimm
Published: May 2024

Many scholars and commentators have argued that the membership in the World Trade Organization (WTO) has resulted in the restriction of developing countries’ trade policy space, preventing them from industrializing and promoting development. The present article has tested empirically this assertion, using a sample of 87 developing countries over period 1986–2020. It has shown that the WTO membership genuinely has restricted developing countries’ trade policy space, and countries that had larger trade policy space have experienced larger trade policy space restrictions. However, these outcomes mask different realities across sub-samples, including Least developed countries (LDCs) - that enjoyed more generous flexibilities in WTO rules - versus NonLDCs, and Article XII member states - those that undertook greater trade liberalization commitments – versus NonArticle XII member states. Finally, countries with larger trade policy space tended to secure a greater trade policy space, as they improved their participation in global trade.

Uptake of core outcome sets in pediatric clinical trials: a protocol
Authors: Lei Ruobing , Estill Janne , Florez Ivan , Li Qiu , Chen Yaolong , Williamson Paula
Published: May 2024

Introduction
A growing number of pediatric core outcome sets (COS) have been developed in the past 20 years. Previous studies have provided many useful insights into the uptake of COS. In addition to the awareness of COS among clinical trialists, some methodology of COS development (especially patient involvement) can promote COS uptake. However, the uptake of COS in pediatric clinical trials needs to be further explored. The aim of this study is to provide information on the rationale and use of pediatric COS in clinical trials, and to analyze in depth the awareness and views of COS developers and clinical trialists about the development and use of COS.
Methods and analysis
We will include all pediatric COS identified in our previous systematic review and those subsequently included in the COMET database. We will extract the data including the target condition, population, intervention, list of core outcomes, and the details of patient involvement. Next, we will search Clinicaltrials.gov for trials on health conditions addressed by the identified COS. The comparability of the scopes in each COS-trial pair and for the outcomes in each clinical trial that are exact matches, general matches, and non-matches with outcomes in each relevant COS will be assessed. Finally, we will conduct a survey and semi-structured interviews among COS developers and clinical trialists to examine their views.
Ethics and dissemination
Ethical approval for the study has been granted by the ethics committee of the Lanzhou University.
Strengths and limitations of the proposed study
The uptake of pediatric COS will be presented and analyzed in a comprehensive manner through comparative analysis of the literature and a combination of quantitative and qualitative methods. There will be language restrictions in the selection of the studies, and the survey and interview sample will include only subjects speaking English or Chinese. Both restrictions may limit the generalizability of our results.

Published: May 2024

One of the most active research areas in robotics is visual place recognition using a 3D laser Lidar. A promising research direction involves learning and recognition of scene descriptors, such as scan context descriptors. These descriptors map 3D point clouds to 2D point clouds. Although the scan-context descriptor has a high recognition performance, it is still expensive image data and cannot be handled with low-capacity non-deep models. To address this, we have developed a novel feature descriptor by combining COG (center of gravity) with scan-context descriptor.

Authors: N.R. Sardar , R.V. Prasad , H.G Bhatt , K.S. Damle
Published: June 2024

Supercritical fluid extraction has emerged as a highly efficient and selective method for extracting essential oils from spices. The aim of this study was to investigate the outcomes of supercritical fluid extraction in terms of both yield and extraction of valuable essential oil from ajwain. Factors such as temperature (35 to 55°C), pressure (100 to 300 bar), dynamic duration (30 to 150 min), and static time (30 to 90 min) were evaluated to determine the concentration of thymol through the use of a central composite design for supercritical fluid extraction, and the extraction process was optimized. The optimal factors were found to be 35°C, 300 bar pressure, 65 minutes of dynamic time, and 30 minutes of static time. The essential oil yield with a thymol content of 60% was 3.9%.
Wheel path planning for flute grinding of non-cylindrical solid end-mills based on circular arc projection
Authors: Ren Lei , Zhang Zheng , Li Yong , Xiang Daohui , Ma Junjin , Cui Xiaobin
Published: June 2024

Flute grinding is a crucial process in solid end-mill manufacturing, because the generated flute parameters, i.e. helix angle, rake angle, core radius, and flute width, have significant effects on the cutting performance of end-mills. However, the flute grinding of non-cylindrical solid end-mills is still challenging due to the variable flute parameters along the tool axis. This paper proposes an accurate and efficient method of wheel path planning for flute grinding of non-cylindrical solid end-mills based on circular arc projection. The wheel path determined by the new method can accurately generate the designed variable helix angle, variable rake angle, variable core radius, and variable flute width. The rake angle is guaranteed by the conjugate condition between the wheel surface and the cutting-edge curve. Equivalent errors of core radius and flute width are introduced in this work based on circular arc projection. The accuracy of the two parameters is ensured by minimizing the sum of squares of the two equivalent errors. Simulations and experiments are conducted to validate the method. Three types of non-cylindrical end-mills i.e. tapered end-mill, tapered barrel end-mill, and barrel end-mill, are considered in the validation. The measured results indicate that the generated flute parameters coincide well with the designed ones at different axial positions of the end-mills.
At the Dawn of Continents: Archean Tonalite-Trondhjemite-Granodiorite Suites
Authors: Laurent Oscar , Guitreau Martin , Bruand Emilie , Moyen Jean-François
Published: June 2024

Archean rocks of the tonalite-trondhjemite-granodiorite (TTG) suite are dominant constituents of Earth’s earliest preserved silicic crust, while conversely rare in Phanerozoic continental crust. Their formation represents the first critical step towards the construction and preservation of continents. Formation of most TTG magmas involved partial melting of hydrous, probably silicified, mafic rocks at various depths (20–50 km, possibly up to 100 km). Many possible tectonic scenarios fit the petrological and geochemical constraints on TTG formation, whether compatible with a global plate tectonic-like regime or not. Refining such scenarios is a major challenge that requires systematically integrating the constraints on TTG formation—relying especially on accessory minerals as key petrogenetic tools—with the geological context on a regional scale.
Archean Geodynamics Underneath Weak, Flat, and Flooded Continents
Authors: Rey Patrice F. , Coltice Nicolas , Flament Nicolas
Published: June 2024

Although a significant volume of crust was extracted from the mantle early in Earth’s history, the contribution of felsic rocks to the sedimentary record was minimal until ~3.0 Ga. On a hotter Earth, this conundrum dissipates if we consider that the felsic crust was buried under thick basaltic covers, continents were flooded by a near-global ocean, and the crust was too weak to sustain high mountains, making it largely unavailable to erosion. Gravitational forces destabilized basaltic covers within these weak, flat, and flooded continents, driving intra-crustal tectonics and forcing episodic subduction at the edges of continents. Through secular cooling, this dual-mode geodynamics progressively transitioned to plate tectonics.
Embracing Craton Complexity at Depth
Authors: Cooper Catherine M. , Miller Meghan S.
Published: June 2024

Variations within individual cratons, as well as across different cratons, are readily apparent at the Earth’s surface, providing indirect insight into the processes governing the formation and evolution of the underlying regions. However, our views at depth are more limited. As such, there is a risk of interpreting the cratonic lithosphere as a monolith. Recent modeling and advances in seismological imaging have enhanced our perspective of vertical variations within the cratonic lithosphere, which has helped build a general conceptual model. While lateral variations also are increasingly identified, their significance still presents unanswered questions. In this review, we summarize the current state of knowledge of cratonic lithospheric structure and demonstrate the importance of lateral heterogeneity in craton evolution and stability.
Fusion surface models: 2+1d lattice models from fusion 2-categories
Authors: Inamura Kansei , Ohmori Kantaro
Published: June 2024

We construct (2+1)-dimensional lattice systems, which we call fusion surface models. These models have finite non-invertible symmetries described by general fusion 2-categories. Our method can be applied to build microscopic models with, for example, anomalous or non-anomalous one-form symmetries, 2-group symmetries, or non-invertible one-form symmetries that capture non-abelian anyon statistics. The construction of these models generalizes the construction of the 1+1d anyon chains formalized by Aasen, Fendley, and Mong. Along with the fusion surface models, we also obtain the corresponding three-dimensional classical statistical models, which are 3d analogues of the 2d Aasen-Fendley-Mong height models. In the construction, the “symmetry TFTs” for fusion 2-category symmetries play an important role.

Authors: Rizqi Febriandika Nur , Puspitasari Cindy , Muslimah Maziyyatul
Published: June 2024

This study investigates the factors influencing impulse buying behavior in online food purchases in Indonesia. The research gathered data from 270 valid respondents from the Muslim community through an online survey (Google Forms). Demographic analysis revealed a predominantly young, single-student population, primarily from Central Java. The study employed the Structural Equation Modeling (SEM) technique to analyze the data and test the hypotheses. The impulse buying tendency scale included seven variables: religiosity, platform quality, social influence, intentions, self-control, consumer mood and Impulse buying tendency. The results indicate that self-control (β: –0.140, p-value: 0.024) plays a crucial role in mitigating impulse buying tendencies whereas religiosity (β: 0.304, p-value < 0.001) can increase the level of self-control. Additionally, platform quality (β: 0.488, p-value < 0.001) significantly impacts individuals’ intention to engage in impulsive purchases. Consumer mood (β: 0.681, p-value < 0.001) is the highest cause of impulse buying behavior. Notably, self-control can reduce impulsive buying tendencies, which means that the higher the self-control ability, the lower the possibility of making impulse purchases. However, the social influence (β: –0.175, p-value: 0.026) has a negative effect on self-control.

Published: June 2024

The study intends to determine how leadership techniques adjusted to the trends impact employee job satisfaction, considering the mediating influence of perceived organizational politics in light of the expanding influence of digital technology and virtual work settings. The study included a solid sample of 300 workers from different parts of Jordan. The employees filled out the questionnaire anonymously. 5-point rating Likert scales were used to capture a range of viewpoints. Using the Partial Least Squares software, this study applies Structural Equation Modelling analysis to examine the relationships between job satisfaction, perceived organizational politics, and leadership styles in Jordanian insurance companies. The study focuses on all employees of insurance companies in Jordan, including people working at various administrative levels. The most common length of job tenure was between one and five years (38.67%). Initial results show a strong beneficial relationship between transformational leadership philosophies and contentment at work (β = 0. 378, t = 6.266, LL = 0.483, UL = 0.718, p < 0.001). Similarly, transformational leadership had the highest standardized effect on perceived organizational politics with a coefficient of 0.443. Furthermore, the complex processes by which leadership philosophies tangentially affect job satisfaction levels are revealed by the role of mediation of perceived organizational politics.

Published: June 2024

O presente trabalho propõe-se a analisar a condição das pessoas em situação de rua como grupo vulnerável, visando a diferenciá-lo de minorias sociais. Essa distinção é vital para compreender qual deve ser a forma de agir do Estado ante às dificuldades enfrentadas pelos grupos vulneráveis, objetivando atender às necessidades específicas destes. Considerando a vulnerabilidade das pessoas em situação de rua, o objetivo do trabalho parte deste enquadramento para, então, compreender se a função social da propriedade interfere na efetivação dos direitos da personalidade destas pessoas. Como objetivos específicos visou-se a analisar se há garantia dos direitos da personalidade das pessoas em situação de rua a partir do princípio da função social da propriedade como instituto de direito fundamental constitucional, e, por fim, entender se a vulnerabilidade das pessoas em situação de rua está relacionada com a (in)eficácia da função social da propriedade. O método de pesquisa utilizado foi o dedutivo, partindo da estruturação de raciocínio lógico pautado na pesquisa bibliográfica com abordagem qualitativa, por meio de revisão não sistematizada de artigos publicados em periódicos, doutrinas e legislações correlatas. Ao final da pesquisa constatou-se que a violação dos direitos da personalidade das pessoas em situação de rua tem ligação não apenas com a vulnerabilidade explícita destas, mas, também, com a ausência de efetivação da função social da propriedade. É por esse motivo que se faz necessário o desenvolvimento de institutos legais que visem à oportunidade de moradia para as pessoas em situação de rua, buscando a garantia de moradia e propriedade, seja por meio de normativas facilitadoras de aquisição ou por políticas públicas, cumprindo com o princípio da função social e garantindo que essa população tenha os direitos da personalidade resguardados.

Published: June 2024

Sign language (SL) is vital in fostering communication for the deaf and hard-of-hearing communities. Continuous Sign Language Translation (CSLT) is a work that translates sign language into spoken language. CSLT translation is done by changing continuous forms into isolated signs. Segmenting morpheme signs from phrase signs has several challenges, such as the availability of annotated datasets and the complexity of continuous gesture movements. The Indonesian Sign Language (SIBI) system follows Indonesian grammatical norms, including word formation, in contrast to other sign languages with rules derived from their spoken language. In SIBI, a word can consist of a root word and an affix word. Therefore, temporal action segmentation in SIBI is important to reconstruct the results of translating each sign into spoken Indonesian sentences. This research uses an optical flow approach to segment temporal actions in SIBI videos. Optical flow methods that calculate changes in intensity between adjacent frames can be used to determine the occurrence of sign movement or vice versa to determine the delay between sign movements. The absence of intensity differences between the two frames indicates the boundary between sign gestures. This study tested the use of dense optical flow on videos containing SIBI sentences taken from 3 signers. Evaluation is done on several parameters in the dense optical flow algorithm, such as threshold size, PyrScale, and WinSize, to obtain the best accuracy. This paper shows that the optical flow algorithm successfully performs segmentation, as measured by Perf and F1r. The experimental results showed that the highest Perf and F1r yields were 0.8298 and 0.8524, respectively.

Heterogeneous electro-Fenton removal of polyacrylamide in aqueous solution over CoFe2O4 catalyst
Authors: Xu Shanshan , Yang Yi , Li Fanxiu
Published: June 2024

Polyacrylamide (PAM) in environmental water has become a major problem in water pollution management due to its high molecular mass, high viscosity and non-absorption by soil. CoFe2O4 with strong magnetic properties was prepared by solvent-thermal synthesis method and used as the catalyst for the removal on PAM in heterogeneous Electro-Fenton (EF) system. It showed that the removal efficiency of PAM by the heterogeneous EF system using CoFe2O4 catalyst was 92.01% at pH 3 after 120 min. Further studies indicated that ·OH was the most significant active species for the removal of PAM, and the contribution of ·O2− and SO4·− for the removal of PAM was less than 15%. The reusability test and XRD, XPS, FTIR analyses proved that the catalyst had good stability. After a repeated use for five times, the catalyst still had a high PAM removal rate and stable structure. The valence distribution and functional groups of the phase components of the catalyst did not change significantly before and after the reaction. The possible mechanism of catalyst activation of H2O2 was deduced by mechanism investigation. The CoFe2O4 is an efficient and promising catalyst for the removal of PAM wastewater.

Os dados dos questionários foram analisados no programa estatístico SPSS/PC por meio de frequências e testes estatísticos não-paramétricos e das entrevistas por meio de interpretações. Os resultados revelam que a percepção de segurança no Parque Olímpico do Rio de Janeiro, sustentada pelo desconhecimento de assaltos, é afetada positivamente pela presença de cercamento. Por sua vez, o fato de as pessoas sentirem falta da maior supervisão de guardas em grandes áreas abertas, mesmo que cercadas, poderia ser tratado também pela inclusão de equipamentos e atividades que sirvam como atratores de usuários e, logo, contribuam para a supervisão dessas grandes áreas, tais como bares e/ou cafeterias e pistas de caminhada, corrida e skate.

O artigo trata da dinâmica de uma análise ambiental quando integrada ao Sistema Building Information Modeling –BIM. O objetivo é aplicar estratégias de tomada de decisão comprometidas com o desempenho ambiental a partir de um caso de retrofit de edificação nesse ambiente. A importância deste tema vem da convergência de ferramentas de análise ambiental; BIM; e tomada de decisão. Além disso, no que diz respeito à integração do software no processo de design do ambiente virtual BIM. Acredita-se que o BIM por meio da parametrização e modelagem tridimensional pode favorecer uma análise ambiental para o projeto arquitetônico, criando condições adequadas para uma abordagem multicritério e possibilitar o desenvolvimento de edificações sustentáveis de alto desempenho. Assim, uma análise é realizada de um processo de tomada de decisão para um caso de retrofit de edificação, considerando as complexidades dos problemas ambientais reais e virtuais. As relações de geometria e informação, relativas à modelação, parametrização e interoperabilidade são consideradas através do sistema BIM. O método de decomposição utilizado segue os níveis de desenvolvimento BIM do BuildingSMART e do American Institute of Architects - AIA. O método ELECTRE III suporta o processo multicritério de apoio à decisão. O objeto de estudo se limitou à análise térmica e obteve como resultado a solução dominante (a melhor solução) para proteção por venezianas contra a radiação solar nas fachadas de vidro orientadas a NO e SO da edificação.

Atentos aos benefícios a serem desfrutados por moradores ao imergir junto à comunidade, a Ciência da Prevenção possibilita a qualificação de ações comunitárias tendo o território como base interventiva. O Communities That Care (CTC) é um sistema de prevenção que vem se destacando como modelo internacional sobre intervenções multiníveis baseadas em evidência, como base em estudos dos determinantes sociais e ambientais. Objetivou-se estabelecer uma interlocução entre a Psicologia Ambiental e o referido sistema de prevenção, ao compreender a influência das vinculações de identidade e de apego ao lugar para adesão das lideranças comunitárias ao Communities That Care. O contexto da pesquisa envolveu um dos distritos de Florianópolis e todas suas particularidades. O percurso metodológico envolveu as técnicas de caminhada pelo local, vestígios ambientais e entrevistas semiestruturadas. Os dados colhidos foram apreciados à luz da Análise Temática e suscitaram a criação de duas categorias de análise, são elas: afeto e interações; lugar e pertença. Os principais resultados evidenciaram como pontos de inflexão na dinâmica relacional a percepção de relevância das práticas culturais, cuidado socioambiental, segurança e habitabilidade, identificação e afetividade para com a comunidade. A relação estabelecida com a comunidade, principalmente a identidade e o apego ao lugar, aos seus valores e engajamento em ações coletivas, potencializam a adesão ao Sistema de Prevenção Communities That Care e facilitam o planejamento de ações comunitária de âmbito preventivo ao uso de drogas e violências.
A PÓS-VERDADE PELO VIÉS DA TEORIA DA DISSONÂNCIA COGNITIVA
Authors: Neves Barbara Coelho , Pereira Oliveira Renan
Published: June 2024

The present article aims to establish a conceptual articulation between the phenomenon of post-truth and Cognitive Dissonance Theory, created by psychologist Leon Festinger in 1957 and subsequently adopted by the field of communication to understand the process of information selection/exclusion by the public. Festinger pointed out in his empirical study that people tend to seek information to reinforce their own beliefs and pre-existing opinions. The proposal here is to make a theoretical/conceptual approximation as an attempt to identify a theoretical framework in the fields of communication and psychology to analyze post-truth and the consequent context of fake news. We employed the methodology of literature review to map some works already produced on the topics, mainly in the field of communication. In conclusion, we find that Cognitive Dissonance Theory proves to be valid as a theoretical, bibliographical, and conceptual basis for elucidating, at least in part, the phenomenon of post-truth.

Introduction

Core buildups are usually maintained by the usage of posts. Even so, in curved and narrow canals, such as bifurcated premolars, excessive dentin removal during post-space preparation can result in a vertical root fracture or perforation. In order to preserve root canal dentin during post-space preparation of bifurcated premolars, this study examined and analyzed the effects of two widely used drills: Peeso Reamer (Dentsply Maillefer, Ballaigues, Switzerland) and ParaPost (Coltene/Whaledent, Inc., Altstätten, Switzerland). We also examined the risks associated with using Cone-beam Computed Tomography (CBCT).

Methods

Three operators with varying levels of experience treated a total of 72 removed bifurcated premolars, dividing them into equal groups. The rotary ProFile system (Dentsply Sirona, Charlotte, NC) was utilized for root canal treatments, and gutta-percha size #30/0.4 was used for obturation. Peeso Reamer #2 and ParaPost #1 were then used to prepare the palatal canals. CBCT was used to assess the total mean intracanal spaces of 3 mm, 5 mm, and 7 mm that were measured both preoperatively and postoperatively. To compare the mean dentin thickness within the canal area across all groups, we used analysis of variance testing. We detected complications, like deviations or perforations, using mesiodistal periapical radiographs.

Results

When utilizing the Peeso Reamer, the mean dentin thickness (0.749 mm) was slightly more than when using the ParaPost (0.736 mm) with p=0.16. There was no significant difference in the mean dentin thickness of the canal area between the Peeso Reamer and the ParaPost drills. The Pesso Reamer drill had fewer complications since it matched the canal configuration, while the Parapost drill removed somewhat more dentin in the canal area. Only seven teeth with minimum deviation from the center of the canal during preparation were produced by the Peeso Reamer drill (20% of teeth having deviation), whereas twenty-one teeth had deviations (72.2% of teeth) and eight had furcal perforations generated by the ParaPost.

Conclusion

Within the limitations of our study, the Pesso Reamer drill caused little more dentin removal than the ParaPost drill. However, the Peeso Reamer had fewer risks and was safer to use in bifurcated premolars. The ParaPost drill is not recommended in bifurcated premolars due to the high risks of deviation and perforation because they have narrow canals. The selection of an appropriate drill for post-space use in bifurcated premolars is essential for successful patient outcomes.
