Published: June 2024

The aim was to compare the reproducibility of the traditional manual analysis of the right ventricle (RV) strain with a semi-automatic analysis (an automatic method with the possibility of adjustment) in speckle-tracking echocardiography (STE).

Materials and methods. Evaluation of RV by speckle-tracking echocardiography was performed in 71 patients with two approaches: manual (Q-Analysis) and semi-automatic (AutoStrainRV). Such parameters as RV global longitudinal strain (RVGLS), RV longitudinal free wall strain (RVLFWS), RV longitudinal free wall segmental strain, and the amplitude of movement of the tricuspid annular plane systolic excursion (TAPSE) were compared.

Results. There were no significant differences between the values of RVGLS (21.9 ± 4.7% vs. 21.6 ± 3.6%, p = 0.488, respectively) and RVLFWS (24.6 ± 5.1% vs. 25.3 ± 4.6%, p = 0.212, respectively) obtained by manual and semi-automatic strain analysis. The significant differences were revealed in the values of RVLFWS in the basal and middle segments estimated by a semi-automatic method and by a manual method (22.6 ± 7.1% vs. 27.0 ± 10.1%, p < 0.002, and 23.8 ± 5.9% vs. 25.8 ± 8.0%, p < 0.05, respectively). Bland-Altman analysis showed mean bias for RVGLS -0.31 (95% CI: -7.62–7.00) and for RVLFWS - 0.70 (95% CI: -8.44–9.83). The values of the TAPSE obtained by semi-automatic analysis were lower and significantly different from the values calculated in the M-mode (22.6 ± 3.8 mm vs. 24.9 ± 4.5 mm, p < 0.001). Strain analysis by the semi-automatic method requires less time than the manual method (22.9 ± 4.5 seconds vs. 38.9 ± 7.8 seconds, p < 0.05).

Conclusions. The choice of approach for RV strain assessment (manual or semi-automatic) does not significantly affect the values of RV strain but may affect the result of segmental RV strain in the basal and middle segments. The semi-automatic strain analysis of RV provides a faster and more reproducible assessment of RV function. The values of the TAPSE by semi-automatic strain analysis are significantly lower compared to the values of the TAPSE in M-mode.

In some channels with high gradients, heavy scouring and erosion, as well as overflow, is highly common to occur, thus it is required a water flow velocities regulation. An option for achieving this, is to significantly increase the channels’ s bottom roughness through the installation of rapid hydraulic structures. However, in sedimentary density fluids, the change of velocity generates the deposition of solids which could be consolidated by changing the geometric design of these structures. This study aims to estimate the degree of confidence expected when modifications take place to artificial roughness geometries in the bottom of the channel with turbulent flow and sediment flow. This modification requires to transverse ribs into ramps using an experimental mathematical analysis. The study allows us to conclude that the newly generated bottom roughness causes more stable water flows, and it is a way to reduce flow velocities.

Authors: Audrey Angela , Lukman Hendro , Sriwati Sriwati
Published: June 2024

Since 2014, there has been a massive increase in infrastructure development. The interesting thing about this industry is a decrease in the share price of these companies, especially state-owned companies that are mostly working on the infrastructure development. According to this phenomenon, a study was conducted to determine the effect of corporate governance and the characteristics of the board of directors on firm value which is a reflection of value of share in the market price. The characteristics of the board of directors consist of age, gender, tenure, and educational background. The audit committee, independent commissioners, and the board of commissioners are proxies for corporate governance. The data used are state-owned infrastructure companies listed on the Indonesia Stock Exchange from 2015-2022. The number of companies is 8 companies. The analysis uses multiple regression analysis, and they processed with Statistical Product and Service Solution (SPSS version 29). The results of this study indicate that the audit committee, age of directors, and educational background of directors have a significant effect on firm value. Meanwhile, the independent commissioners, board of commissioners, gender of directors, and tenure of directors do not affect firm value. The conclusion is that the role of the audit committee and the age and education of the board of directors play an important role in firm value. This study implies that the selection of the audit committee and the age and educational background of board members are the prominent focus of recruitment in a company to increase firm value.

Authors: Le Kieu Phuong
Published: June 2024

The achievement of sustainable development, which is essential for preserving a healthy world for future generations, depends on the implementation of efficient global governance. Traditional, nation-state-focused approaches struggle to address difficulties that cross borders. In contrast, global governance structures facilitate collaboration by establishing frameworks—such as the Sustainable Development Goals established by the United Nations—and unite a wide range of actors—including businesses, governments, and nations—to exchange resources, expertise, and optimal methodologies. This collaborative effort is essential to tackle complex issues like climate change and poverty, ultimately paving the way for a more sustainable future. This paper will discuss the roles and responsibilities of significant actors contribute largely on sustainable development, focusing on the emerging trend of global governance in the international order. By taking the case of UN’s 17 Sustainable Development Goals, key problems for the public sector and private one will be identified and also provide some further suggestions in improving the implementation of sustainable development.

Published: June 2024

Parameter identification techniques for linear and nonlinear dynamic systems currently show a clear orientation toward black box models, with Artificial Neural Networks occupying a prominent place there. This paper presents a procedure for identifying linear dynamic systems parameters in two stages: in the first, a regressive model is fitted from the excitation and response time records, and in the second, its parameters are identified (matrixes of stiffness and damping) and dynamic characteristics (vibration frequencies and modes) based on the previous model. Artificial Neural Networks of the Adaline type and multilayer Perceptions are used for the first stage. The second stage is fully formulated through matrix algebra, which facilitates its systematic implementation and makes it independent of the complexity or dimension of the studied system. The proposed procedure is intended to operate from experimental records, so special attention is paid to the sensitivity of the results to the data interval and noise in the input signals. For the latter, various noise levels were incorporated into the correct responses obtained under ideal conditions, which respond to Gaussian distribution functions with a null mean and specified standard deviation. The proposed procedure justification, the results with the regressive models, and a study of the sensitivity of the results to the variation in the available data quality are presented.

Authors: Andrade Caio Viana , Siqueira Natércia Sampaio
Published: June 2024

A intervenção do Estado em questões como o discurso de ódio contra grupos minoritários desperta inúmeros e divididos debates a respeito. Logo, o objetivo geral do presente artigo é analisar, à luz do pensamento de Judith Butler, o julgamento, pelo Supremo Tribunal Federal (STF) da Ação Direta de Inconstitucionalidade por Omissão nº 26 (ADO nº 26), em que se determinou a criminalização da homofobia e dos discursos de ódio a esta associados. Opta-se pelo estudo do pensamento butleriano a respeito do tema devido a sua proposta de contrapor conceitos e ideias predominantes, de modo a dar espaço a temas como a não violência e identidade de gênero, até então negligenciados. Para cumprir com esse objetivo desenvolveu-se o trabalho em três seções: 1) A linguagem como agente criador; 2) A política performativa e os efeitos insurrecionais do discurso de ódio; 3) A força da não violência e o contra-ataque à violência estatal; e 4) A criminalização da homofobia pelo STF: entre a justiça, a política do performativo e a força da não violência. Utilizou-se metodologia do tipo bibliográfica e documental, com pesquisa de abordagem qualitativa e pura, tendo como método o hipotético-dedutivo. Conclui-se que a criminalização da homofobia foi a medida correta dianto do caso em questão, pois o combate às diversas formas de violência, como a não violência, depende da coercibilidade e da normatividade do Estado.

Published: June 2024

O presente artigo analisa a jurisprudência da Suprema Corte norte-americana sobre a liberdade religiosa, que deita raízes na formação dos Estados Unidos, encontrando-se garantida na Primeira Emenda à Constituição. Desta se extraem duas cláusulas: Establishment clause, que impõe a separação entre Estado e religião, e Free exercise clause, que estabelece que o governo não pode interferir nas práticas religiosas dos indivíduos. Em relação à primeira, identificam-se dois entendimentos que se intercalaram ao longo do tempo: dos absolutists, partidários de uma rigorosa separação entre Estado e qualquer manifestação religiosa, e dos nonpreferentialists, que admitem uma separação mais branda entre esses setores. A primeira corrente predominou ao longo do tempo, mas a segunda vem conseguindo importantes vitórias nas últimas décadas, especialmente em alguns dos cinco aspectos em que o tema foi dividido. Utilizou-se, neste artigo, metodologia de pesquisa básica quanto à finalidade, descritiva quanto aos objetivos, qualitativa quanto à abordagem e bibliográfica quanto ao procedimento.
Comparison of Hydrocarbon Volumetric Calculation between Cell-Based Model and Numerical Integration
Authors: Oktaviani Vania , Saroji Sudarmaji , Trisna Muhammad Destrayuda
Published: June 2024

Volume estimation for hydrocarbon reserves is a challenging yet pivotal task in engineering for exploration and production. Advances in technology now enable us to compute volume integration using programming computation. Various approaches using numerical integration, including the trapezoidal, pyramidal, and Simpson's rule, along with cell-based models as comparative methods can be used for the calculation of hydrocarbon volume. In this study, original oil in place (OOIP) is employed to determine reserve oil volume.  The OOIP values obtained are 8.55 million m3 through cell-based calculations, 8.63 million m3 via the trapezoidal approach, 8.58 million m3 using the pyramidal method, and 8.57 million m3 with Simpson's 3/8 rule. The relative error ratio percentages between the cell-based model as the reference value and the numerical integration calculations as the measured values are 0.93% for the trapezoidal method, 0.35% for the pyramidal method, and 0.23% for Simpson's 3/8 rule. Simpson's 3/8 rule demonstrates the closest mathematical result to the cell-based model. Within this margin of error, the methodologies have been demonstrated to proficiently compute hydrocarbon reserves from real data through simplified and abbreviated processes.

Geoelectric Modelling Based on Bessel Functions Integral and Damped Least-Square Inversion for Layered Earth Models
Authors: Saefullah Asep , Srigutomo Wahyu , Rostikwati Diana Ayu
Published: June 2024

Apparent resistivity formulations of a geoelectric method for layered Earth have been obtained analytically in the Bessel functions integral. This formulation is obtained through the application of two boundary conditions. First, the current density is zero at the Earth's surface. Second, current density and electric potential are continuous at the boundary between the layers. Geoelectric modelling can be done using several model parameters through this formulation. The modelling results show that apparent resistivity formulations based on Bessel function integrals can simulate apparent resistivity curves for layered earth models. The inversion process uses the apparent resistivity formulation based on Bessel function integrals. In this study, the inversion process uses a dumped Least-squared inversion method. The first step begins by testing the inversion program using synthetic data. After that, the inversion program is used in field data. The inversion results using field data from geoelectric data in Mount Pandan, East Java, show that the program was well done, with a minimal error value of 1.24%.
A combined first-principles and data-driven computational framework to analyze the surface structure, composition, and stability of binary alloy catalysts
Authors: Deshmukh Gaurav , Ghanekar Pushkar , Greeley Jeffrey
Published: June 2024

Pt-based bimetallic alloys are considerably more active than Pt for the oxygen reduction reaction (ORR). This increased activity has been attributed to weakening of the adsorption of ORR intermediates due to the presence of Pt “skins.” Density functional theory (DFT) calculations have, in turn, pointed to the importance of surface segregation energies and Pt leaching on the formation and stability of the skins on close-packed surfaces of Pt alloys. The generalizability of these insights across different chemical environments, surface compositions, and facets, however, remains a subject of active research and is the focus of this work. We present a generalized computational framework combining DFT calculations and data-driven methods to predict the stability of different Pt3X (X = Ni, Co, Fe, and Cu) alloy facets under vacuum conditions and in the presence of an electrochemical environment, wherein we analyze the combined effect of segregation, intrasurface phase separation, leaching, and surface oxidation as a function of electrode potential. The analysis reveals that a subtle interplay of these factors influences Pt skin formation and stability, with Pt segregation being a strong function of the surface structure, and continuous base metal dissolution being thermodynamically, although not always kinetically, favored at ORR-relevant voltages.

Soil organic matter (SOM) plays a central role in the global carbon cycle and contributes to storage of C and energy in soils. Farmyard manure (FYM) addition to arable soils is a measure to increase SOM content, microbial activity and abundance of microbial metabolites (e.g., necromass (NM) markers). However, understanding the mechanistic links between soil dynamics and energy storage is hampered due to the chemical complexity of SOM. Non-targeted molecular-level methods like liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry (LC-FT-ICR-MS) can be used to explore the complex dynamics of SOM, revealing energetic fingerprints and long-term changes in SOM due to FYM addition. We compared water-extractable organic matter (WEOM) from soils of four long-term FYM addition experiments with representative WEOM signatures from maize, bacterial and fungal NM. Long-term FYM addition increased the complexity of WEOM, most pronounced in polar, unsaturated, oxidised and energy-poor compounds. These changes were linked to a 2-3-fold increase in bacterial, plant and fungal NM signatures. Especially bacterial NM in FYM-amended WEOM indicated a shift in dominant energy use channels. Control soils showed a much lower overlap with all NMs, but indicated a higher dominance of fungal energy-use channels, especially for N-containing compounds. A large fraction of WEOM signals (79% in FYM-amended, 94% in control soils) was unrelated to any of the three NM signatures, and was also mainly responsible for the shift in nominal oxidation state of carbon (NOSC) between the fertilisation treatments. LC-FT-ICR-MS provided access to ~600 novel microbial NM markers which are readily soluble and compositionally distinct from classical NM markers (ergosterol, aminosugars, etc.). Overall, we highlight novel insights into NM contribution to SOM by LC-FT-ICR-MS, and how it can assist to constrain compositional and energetic impacts of FYM addition on soils.
The Behavioural Change of Distribution Networks with Increasing Circuit Length and Load
Authors: Essilfie J. E. , Amoah P. K.
Published: June 2024

Purpose: This study investigated the behavioural change of distribution networks with increasing circuit length and load.
Design/Methodology/Approach: This study employed a simulation-based experimental design using OpenDSS to model and analyse the behaviour of the distribution network under different scenarios. A combination of varying network lengths and loading levels was chosen to determine the behavioural changes of a network. A total of 100 simulations were conducted, representing 10 different circuit lengths and 10 different loading conditions. Data collection on voltage levels at various points along the circuit, focusing on the voltage at the end of the circuit was carried out. Each scenario will be modelled and analysed to study the voltage drop and stability. The simulation results were validated by comparing them with theoretical calculations and real-world measurements from similar networks.
Findings: It has been shown that, for every circuit length there is a maximum load that will result in a linear relationship maintaining the correct energy balance to respond to voltage regulation and power flow. With circuit length increase, capacitive reactance reduces while resistance and inductive reactance increase leading to a more inductive circuit.
Research Limitation/Implications:  The research considered only changes in circuit length and loading as it was based on a simplified source-load equivalent circuit.
Practical implication: It draws the attention of practising engineers and designers to be mindful of the implications of load increase and network expansions on system characteristics. It forms a guide to the limit a circuit could be extended or loaded if system balance is to be maintained.
Social Implication: A stable and reliable power supply supports economic growth, public health, and safety, leading to improved quality of life. Ensuring all communities have reliable electricity fosters social equity and inclusion, promoting fairness and improving the quality of life for disadvantaged groups.
Originality/Value: The novelty of this research lies in its comprehensive, realistic, and advanced approach to studying the behavioural changes in distribution networks with increasing circuit length and load. By addressing previously overlooked aspects and integrating modern computational and data analysis techniques, the study provides valuable new insights that can significantly improve the design, operation, and management of long distribution networks.
Non-native common snapping turtle Chelydra serpentina (Linnaeus, 1758) in Western Europe: a focus on Central Italy showing evidence of a hot spot of introduction

The common snapping turtle, Chelydra serpentina (Linnaeus, 1758), is a robust aquatic turtle native to southeast North America. However, it has also been introduced to other countries through the exotic pet trade, where it has gained popularity due to its distinctive appearance and impressive size. Over the past decade, a considerable number of individuals, abandoned by their owners, have been recorded and captured in Western Europe. Here, we report the first comprehensive summary of records at continental scale, showing that France and Italy represent the countries with the highest number of sightings. In France, exhibition, exchange, or sale events of exotic animals (until 2022 legal; now illegal) have been located near large cities, although records of C. serpentina were significantly higher outside the core of urban areas. We also recorded a significant increase in total number of records at European scale when comparing the periods of 2010-2015 and 2016-2020. Finally, we focused the current study on a peculiar spatial pattern at local scale (Central Italy) near an important site of exhibition and sale events of exotic animals, suggesting the presence of a hot spot of introduction. Popular events may represent critical colonization hubs from where these freshwater turtles can disperse into the surroundings.

No Brasil a criação de pequenos ruminantes é uma atividade bem difundida chegando ao número de 9.592,079 milhões de cabeças e a região nordeste é a que apresenta a maior percentagem que chega a 93,0% (8,9 milhões de cabeças) (IBGE, 2017).
            Dentre os animais criados temos várias raças e dentre elas as nativas apresentam uma boa alternativa para à agricultura familiar, pois geralmente no modelo de criação adotado não há o emprego de produção especializada afim de aumentar os índices zootécnicos,  já que o objetivo da criação é basicamente o consumo da família e venda do excedente, a criação de caprinos e ovinos nativos é de forma extensiva e por sua rusticidade os animais já adaptados não sofrem da mesma forma quanto os animais exóticos sendo eles mais produtivos.
            O uso do cruzamento com raças mais produtivas é uma boa opção para aumentar à produtividade, entretanto não deve ser usado sem critérios e sim de forma a ser sustentável, afim de elevar a produtividade sem perder as caracteristicas adaptativas adquiridas em anos de sobrevivência das raças nativas em nossa realidade de clima e vegetação.
            As raças nativas brasileiras, sobre tudo, as de caprinos e ovinos estão sobre forte ameça de permanência e isto se acentuou com a entrada de raças exóticas que são utilizadas com a finalidade de incrementar e difundir material genético, no entanto, quando feita de forma indiscriminada pode comprometer a existencia de raças nativas.

Uma Breve História da Igualdade
Authors: Amorim Castro Júlio César
Published: June 2024

As lições aprendidas, após a leitura desse livro de Thomas Piketty, é que o Estado social e o imposto progressivo são “ferramentas” poderosas que permitem transformar o capitalismo. Porém, esses mesmos fatores: Estado social e imposto progressivo permite estabelecer as bases de uma nova forma de socialismo democrático, no instante em que ambos podem diminuir a desigualdade e aumentar a igualdade. As transformações sociais, tributárias e jurídicas são elementos fundamentais para se obter a igualdade, mas requerem mobilização social e política, ou senão a igualdade não se é alcançada.
