Uma análise do impacto dos gastos militares nos investimentos privados no Brasil
Authors: Leske Ariela , De Morais Lima Rafael , Conte Carlos
Published: January 2024

Foram realizados testes econométricos para analisar empiricamente a relação entre os gastos militares e os investimentos privados no Brasil em dois períodos: de 2000 a 2018 e de 1977 a 2018. Foram utilizados os modelos Mínimos Quadrados Ordinários (MQO) e o Auto Regressive Dependent Lagged (ARDL) com o Teste de Limites, para analisar a relação entre as variáveis. A análise econométrica demonstrou que em nenhum dos modelos analisados se verificou relação estatística entre os gastos militares e os investimentos privados no Brasil, nem no curto, nem no longo prazo. Os resultados se mantiveram para a análise alternativa que desagregou os gastos militares em investimentos em equipamentos e em demais gastos. A teoria do Salário Social de Smith (1980) aparenta ser insuficiente para explicar a situação do Brasil, uma vez que não há evidências de crowding-out (substituição) nem crowding-in (complementariedade). Logo, os resultados apontaram que os gastos militares e os investimentos privados no Brasil podem não serem relacionados, enquanto outras variáveis macroeconômicas, como a taxa real de crescimento do PIB e a taxa de desemprego, possuem um efeito estatisticamente significativo sobre os investimentos privados.

Published: January 2024

This work estimated the degree of vulnerability to soil erosion (GVES) based on the relationship between the natural erosion potential (PNE) and the soil loss tolerance limit (LTP), applied to the State of Paraíba using geoprocessing techniques for modeling the data based on information contained in the representative profiles of the Soil Bulletins of the State of Paraíba and the Agricultural Zoning of the State of Paraíba and on rainfall and altitude data. The results showed that the use of geoprocessing and kriging techniques allowed estimating and mapping the degree of vulnerability to soil erosion. The K Factor, even appearing in the very high class observed by the R and S Factors, leading the LTP to the Degree of Vulnerability to Soil Erosion (GVES) to present itself in good proportion in the middle class, smoothing the result. Despite its limitations, the information generated in this study of the knowledge of the spatial variability of vulnerability can be used in decision-making and serve as support for conservation planning, thus being able to develop strategies for management and conservation of soil and water. The distribution was symmetrical, the kurtosis indicated a platykurtic distribution, where the greatest variations in amplitude and irregular distribution were present in the variables Factor K and LTP. The greatest regularity was in Factor R, in which the Shapiro-Wilk test showed the smallest difference between them. It could be said that there is similarity and agreement between the tests used in this work and led to accept the normality of the data.
License to Gamble: Discursive Perspectives on the 2019 Reregulation of the Swedish Gambling Market
Authors: Goedecke Klara , Spångberg Jessika , Svensson Johan
Published: January 2024

During the last decades, several European gambling markets have been reregulated. In 2019, it was Sweden’s turn; the former oligopoly was replaced by a licensing system. In this article, the governmental inquiry in which the new system was proposed, outlined, and justified is studied using discourse analysis. Medical, public health, and free market discourses have been shown to dominate articulations of gambling in several national contexts, but the ways in which these discourses interact, overlap, and differ are crucial to understand better in order to appreciate the production and legitimation of meanings around gambling. Moreover, the 2019 reregulation has not yet been studied from discursive perspectives; thus, the article makes both theoretical and empirical contributions. The article demonstrates that market and medical discourses structure the inquiry. While they sometimes overlap and merge, their co-existence also causes tensions, for instance regarding whether an increase in gambling is acceptable or not. The article points to a strengthening of market and medical discourses and a weakening of public health discussion within Swedish gambling debates.
Knowledge of Play: A Precursor for Rethinking Sports Gambling Among Young Africans
Authors: Adebisi Tunde
Published: January 2024

The degree of involvement in sports gambling activities differs among individuals, in terms of knowledge of the sport they gamble on, and betting dynamics. These sorts of differences have created distinct classes of bettors within the youth gambling population, where the lower strata consult members of the highest stratum to maximise gambling success. This article suggests that, within what is known as a youth gambling population, a community of gamblers exists. This demonstrates the necessity to avoid or mitigate the tendency to treat the youth gambling population as a unified whole. The article also articulates important dynamics of sports gambling culture among young people and explains how the activity is perceived and encouraged among/within a gambling community.
Film Poster Design: Understanding Film Poster Designs and the Compositional Similarities within specific genres
Authors: Pooranalingam Sneha
Published: January 2024

A film poster is an integral part of the promotion and marketing of an upcoming film. It encapsulates the essence of the film and is used in theatres, DVDs, and advertisements. For effective promotion, designers must create film posters that are relevant to the film they represent. This study explored whether film posters have common compositional aspects within genres. Previous research has explored genre classification and colour theory within film posters. However, the analysis of composition within film posters has been insufficiently researched in the context of recognizing patterns throughout film genres. I explored four film genres and analyzed existing film posters within these genres using a visual analysis tool. The analysis was then used to define a summarized composition of each genre, which then created generated posters using this analysis and definition. These generated posters consisted of low fidelity posters made using basic shapes such as circles and squares. The posters were used in participant interviews which followed a semi-structured approach. I asked participants questions to further their reflection about the posters and create discussion. Each participant was asked to label each poster with a genre based on their understanding of what they would assume to be the genre of the generated film poster. After analyzing the results from the participants’ decisions, the findings indicate that film posters have similar compositions within genres. These similarities are further recognized by film consumers and impact consumers’ perceptions of film posters.
Two-photon decay of the pseudoscalar meson in the relativistic quark model
Authors: Haurysh V. Y. , Andreev V. V.
Published: January 2024

In the relativistic quark model, based on the point form of Poincaré-invariant quantum mechanics, an integral representation of the form-factor of the pseudoscalar P0(π0,η,η′) meson of  P0 (qq̅)→γγ decay is obtained taking into account the anomalous magnetic moments of u-, d- and s-quarks. IIn the developed formalism the values of the constituent quark masses and the parameters of the wave functions are calculated using the lepton decay  P±(qQ̅ ) → ℓ±νℓ± constant fP± and the pseudoscalar density constant gP±. It is shown that taking into account the gluonium component in η/η′-mesons and using the structure functions of light sector quarks lead to the behavior of the form factors of pseudoscalar π0-, η-, η′-mesons in the area of a small transferred momentum to the lepton pair, which is consistent with the modern experimental data

Published: January 2024

A multi-stage technique for applying insulating coatings to metal powder particles has been developed in order to create a new class of Fe-based soft magnetic materials with improved characteristics. The density value calculated from the data of X-ray diffraction analysis is approximately 3 % higher than the experimentally measured values, which are 7.4–7.45 g/cm3. The low porosity of the composites is confirmed by the SEM and EDX results. The proposed method of encapsulation of iron powder with an oxide layer is a highly economical method for applying coatings of various chemical compositions to metal powders, and can be widely used in practice to obtain electrical materials. Comprehensive studies of the properties of the obtained samples of powder composite materials based on ABC100.30 iron, the particles of which are encapsulated with phosphorus oxide, have been carried out. It has been established that in a field of 1.5 T, the losses at a frequency of 1 kHz decrease 10 times with an increase in the thickness to 30 nm. The synthesized materials are recommended for use in the development of various types of high-frequency electric motors, generators, chokes, magnetic circuits and electrodes for high-frequency welding and other applications.
Ceramic matrix composite based on silicon carbide and nanostructured nitrogen-doped carbon for supercapacitor electrodes
Authors: Solovei D. V. , Grinchuk P. S. , Kiyashko M. V. , Akulich A. V.
Published: January 2024

The results of studies on the production of a porous ceramic-matrix composite material C–N/SiC from silicon carbide and nitrogen-doped nanostructured carbon for subsequent use as supercapacitor electrodes are presented. The material is formed by pressing silicon carbide micropowder (1 µm) and impregnating with a solution of carbamide (nitrogen source) in phenol-formaldehyde varnish (carbon source), curing and pyrolysis in a nitrogen atmosphere. The maximum concentration of carbamide was obtained in the solution (16 wt.%) at 50 ºС with a viscosity of 134.3 mPa⋅s. Thermogravimetric analysis in nitrogen of the cured solution revealed multistage decomposition with a residual mass of C–N of 48 % at 1000 ºС. Studies of the elemental composition showed a nitrogen content of 1.4 wt.% in C–N/SiC composite (up to 7 % of C–N active mass). In the composite structure, the C–N carbon-nitrogen layer (up to 12 wt.%) distributed inside the matrix pores and covering the SiC grains is X-ray amorphous has a complex nanoscale relief with an average pore size of 1.0–1.5 nm. According to electrochemical studies, the specific capacitance of the C–N/SiC material and the C–N active layer is 16.84 and 153.2 F/g respectively, and the equivalent resistance of the test supercapacitor cell with C–N/SiC electrodes is 0.567 Ohm for samples with maximum doping. The electrodes operate according to the sorption-desorption mechanism of charge accumulation and release, which is typical for a classic supercapacitor based on a double electric layer without the presence of redox reactions on the electrodes. The influence of technological regimes of pyrolysis on the electrophysical parameters of the cell is revealed: lower values of the pyrolysis temperature and nitrogen pressure in the chamber lead to an increase of the material specific capacitance and reduction of the cell equivalent resistance. The obtained results demonstrate the possibility of utilizing C–N/SiC material for the manufacture of supercapacitor electrodes.
New in the hydraulics of channels with permeable walls: indicator of the relative value of the dissipation

Published: January 2024

The factors that have led to the creation of the scientific direction “hydraulics of variable mass” to study the fluid movement laws in channels with permeable walls are indicated. The results of applying of the dynamics of a variable mass point for describing the flow in such pipelines are presented. It is noted unjustifiability of the second Newton’s law generalization to the case of motion of a variable mass point for hydrodynamics problems. The functionality of one-dimensional and multidimensional models of fluid motion in permeable channels based on the classical equations of fluid and gas mechanics is characterized. It is substantiated the dominance of one-dimensional models in engineering computational practice, and a number of contradictions in the description of fluid dynamics are shown (with the flow visualization). On the base of the new kinematic image (instead of the generally accepted “solid jet”, when fluid particles are separated or joined), it has been obtained a one-dimensional equation of fluid motion in a permeable channel in which the friction coefficient is an indicator of the relative magnitude of the energy dissipation of the flow. The dependence of the Coriolis coefficient on the flow regime is constructed. The structure of the friction drag coefficient of a permeable channel has been studied using the vector dimension of length. It is shown that the dissipation of the flow energy in a permeable channel is higher both during outflow and inflow of liquid than in channels with solid walls at the same flow rates. The results are in demand in the development of chemical technology devices, nuclear reactors with microfuel elements, filters and heat exchangers containing channels with permeable walls.

Traditional healers co-exist with orthodox medicine, especially in cases with perceived supernatural causes and during outbreaks of infectious diseases like the Ebola virus disease (EVD) in the North Kivu and Ituri provinces in the Democratic Republic of the Congo (DRC). In this study, we examined the role and potential of involving traditional healers in the national response to the Ebola virus disease outbreak in the DRC. Seventeen community leaders and 20 traditional healers were interviewed. The traditional healers managed symptoms with herbs and were not inclined to refer cases to orthodox healthcare facilities because of their confidence in their ability to handle cases with supernatural causes. The community leaders attested to the acceptance of the traditional healers in the communities, which they attributed to the efficacy of traditional healing, its uncomplicated treatment process, cause of the prolonged cough, as well as cost and the need for secrecy. Traditional healers can be educated to promptly refer cases to Ebola treatment centers for timely diagnosis and appropriate treatment.

Published: January 2024

The microstructure of the heat affected zone (HAZ) and fusion zone (FZ) in the as-welded condition of a single-pass weld performed by the flux-cored arc welding (FCAW) process was studied in a P91 steel using microhardness measurements, field-emission scanning electron microscopy, transmission electron microscopy, and x-ray diffraction. The evolution of precipitates in each region of the single-pass weld was analyzed, and particular attention was paid to the presence of retained austenite (RA). Experimental observations indicated that M23 C6 carbide played a major role in the thermal cycle associated with the weldment. On one hand, the dissolution of M23 C6 led to the precipitation of spherical NbCN in the finegrained HAZ (FGHAZ) near the coarse-grained HAZ (CGHAZ). On the other hand, the total or partial dissolution of M23 C6 carbides changed the chemical composition of the initially formed austenite. In the regions where the M23 C6 carbides were completely dissolved (i.e., the CGHAZ and FZ), retained austenite was observed as a thin, continuous film along primary austenite grains and lath boundaries. Instead, a shell of retained austenite was observed around some partially dissolved M23 C6 of the intercritical HAZ (ICHAZ) and FGHAZ.

The student graduation rate in all universities can be measured by looking at their study duration, both on time and delayed. Thus, by observing the study duration, it can affect the quality of study programs in universities. The purpose of this research is to apply and compare the Naïve Bayes, Decision Tree, Artificial Neural Network, K-Nearest Neighbor (K-NN), and Support Vector Machine (SVM) algorithms in predicting the graduation rate of students. The dataset in this research consisted of 807 student data from the Faculty of Engineering, Universitas Hamzanwadi. The data analysis technique used was descriptive statistics by applying the knowledge discovery in a database (KDD) method. The testing of the five algorithms was done by optimizing the data using the SMOTEENN technique, with a data split of 80% for training and 20% for testing, using a random state of 42. Our findings show that the Naïve Bayes algorithm had an accuracy of 92.37%, Decision Tree 91.60%, K-NN 96.95%, SVM 93.13%, and ANN 90.84%. Among the five algorithms tested, the K-NN algorithm had the highest accuracy rate of 96.95%. The predicted results tended to indicate delayed graduation influenced by GPA. Therefore, the institution needs to pay more attention to students predicted to be delayed to improve their GPA each semester, thus promoting timely graduation within the expected time frame.

The purpose of this study is to apply an optimal machine-learning classification method for weather prediction. The method used is the Gaussian Naïve Bayes model, which has been optimized using Univariate Feature Selection ANOVA-f test and Hyperparameter Tuning GridsearchCV techniques. The data used consists of 6454 daily weather data in Palembang City. There are 5 tests on the Gaussian Naïve Bayes model before and after optimization. The research results show that the optimization of the model successfully improves the performance in weather prediction. The highest accuracy result after optimization reaches 98.33% with 644 test data, an improvement from the pre-optimization accuracy of only 96.95%. Before optimization, the predictions for weather conditions such as sunny, cloudy/rainy, light rain, and heavy rain match the actual data. However, there were 20 prediction errors when dealing with data that should represent very heavy rain conditions. After optimization, the number of prediction errors for the very heavy rain data was reduced to seven. The optimization approach used in this research helps find the most suitable parameter combinations and eliminates irrelevant features, allowing the model to consider only significant features in weather p
