UTILIZAÇÂO DE ESPAÇOS PÚBLICO E PRIVADO NA INSTALAÇÃO E MANUTENÇÂO DE REDES CONDOMINIAIS DE ESGOTO: UMA PROPOSTA DE DISCUSSÃO CONCEITUAL
Authors: Machado Daniela Almeida , Oliveira Maria Teresa Chenaud Sá de , Moraes Luiz Roberto Santos
Published: June 2024

As Redes Condominiais de Esgoto Sanitário-RCE, como parte integrante do Sistema Condominial de Esgoto-SCE, vêm sendo adotadas em várias cidades brasileiras como uma alternativa técnica viável para coleta de esgoto sanitário de domicílios situados em diferentes contextos urbanos, em especial, àqueles em áreas informais de baixa renda. A experiência disponível na literatura, vem propiciando uma melhor compreensão dos aspectos que influenciam positiva ou negativamente na sua adoção, que devem ser conhecidos para serem otimizados. Dentre esses aspectos, fruto de sua concepção e da tecnologia adotada, ressalta-se à necessidade de utilização de espaços privados, dos lotes dos usuários, durante a instalação e manutenção das RCE. A implantação das RCE em áreas privadas, no entanto, poderá gerar conflitos, dos mais diversos, entre os agentes públicos, responsáveis pela implantação e manutenção desta infra-estrutura; as construtoras responsáveis pela execução das obras e os proprietários dos lotes que formam os condomínios. Nesse contexto, este trabalho tem como objetivo apresentar uma proposta de discussão conceitual sobre a utilização de espaços público e privado, quando da instalação de RCE, tomando como referência preceitos da Constituição Brasileira de 1988-CF/88; da LEI Federal nº 10.257/2001 e Código Civil Brasileiro-CCB. O estudo, por meio de conceitos selecionados, fornece indicativos para reflexão e discussão sobre os limites e possibilidades de utilização de espaços privados para instalação e manutenção de RCE, concluindo que a questão poderá ser discutida tanto como um fenômeno de ordem jurídica, quanto um novo conceito de política pública de saneamento, baseado em mecanismos de persuasão em sua ação, comunicação, compensação e diálogo entre Estado e sociedade.

Authors: Moraes Roberto Tadeu Pereira , Neves Elaine Souza das , Santos Luciana Cerqueira Batista dos
Published: June 2024

A bioquímica estuda os fenômenos químicos que ocorrem nos seres vivos. A fluoretação de água para consumo humano é estudada pela química e odontologia. A saliva é um sistema de tampões de pH próximo ao neutro. O esmalte dos dentes interage quimicamente com a saliva trocando íons, em sucessivas desmineralizações e remineralizações. Bactérias do meio bucal produzem ácido lático, que reduzem o pH para <5,5 e dissolvem o fosfato de cálcio que compõem o esmalte dos dentes, na forma de hidroxiapatita, formando as cavidades da cárie. O fluoreto da saliva reage com a hidroxiapatita do esmalte do dente, formando a flurapatita, que resiste até o pH=4,5. É possível adicionar fluoreto ao meio bucal por aplicações tópicas de substâncias fluoretadas. A ingestão de água fluoretada pode adicionar fluoreto ao meio bucal, favorecendo a formação de flurapatita, mais resistente e evitando a doença cárie. O ácido fluossilícico é a fonte de fluoreto mais usada para fluoretação de água para consumo humano. A química da fluoretação de água é ampla e alvo de muitos estudos. Empresas de tratamento de água mantêm controle rígido sobre a dosagem de flúor na água tratada. Alimentos naturais, industrializados e remédios possuem consideráveis teores de flúor. As doenças fluorose dentária e óssea são causadas por ingestão de doses excessivas de flúor. É possível retirar quimicamente o flúor de águas naturais para que se tornem próprias ao consumo humano. A universalização da educação para a saúde bucal pode tornar dispensável o uso de flúor na água tratada.

O serviço de esgotamento sanitário juntamente com as atividades de abastecimento de água potável, limpeza urbana e manejo de resíduos sólidos e drenagem e manejo de águas pluviais compõem os serviços de saneamento básico. O sistema de esgotamento sanitário consiste em instalações operacionais responsáveis pela coleta, transporte, tratamento e disposição final do efluente gerado nas residências, compatível com os parâmetros estabelecidos em legislação vigente, colaborando para promoção da saúde pública e salubridade ambiental. Considerando as recorrentes ocorrências de obstruções nas redes e ramais de esgoto no município de Jequié-BA, este trabalho tem como finalidade realizar uma avaliação do uso das redes e ramais de esgoto pela comunidade local, correlacionando com o descarte indevido de matérias sólidas (lixo). A avaliação foi realizada por meio de pesquisa quantitativa, mediante aplicação de questionário estruturado com 18 questões a uma amostragem de 400 residências visitadas no município. Além disso, foi considerado o número de ocorrências/solicitações para os serviços de desobstrução atendidas pela Empresa Baiana de Águas e Saneamento (Embasa) no ano de 2020. As evidências confirmaram que a presença de resíduos sólidos no sistema de coleta provocam entupimento e traz danos ambientais e financeiros a ambas partes, cabe ressaltar que as presença de lixo nas ruas e avenidas também colaboram para eventos de obstruções, uma vez que quando chove esses resíduos são carregados para a rede coletora de esgoto, mesmo não sendo projetada para atender esse tipo de serviço.

Authors: Salami Olajumoke Olayemi , Spangenberg Erica Dorethea
Published: June 2024

Scientific and technological developments rely strongly on mathematical skills. However, mensuration is a challenging topic in school mathematics, leading to poor performance by many students. Various factors are responsible for the unsatisfactory performance, including inappropriate teaching methods where students passively absorb knowledge transmitted through reading and explanations of textbook contents. Thus, this study examined how a cooperative learning method affected students' performance in mensuration. A quasi-experimental research design was used in the study. The sample comprised two intact classes of 80 students assigned to experimental and control groups selected from one senior secondary school in Ogun State. Data were collected using an adopted standardised mensuration achievement test (MAT), which takes an analytical approach that includes problem-solving, geometric reasoning, formula application, and conceptual comprehension. The results showed a statistically significant difference between the mean score (M=11.18, SD=3.09) of students taught mensuration using the cooperative learning method and the mean score (M=7.66, SD=3.32) of students taught mensuration without using the learning method of teaching (t (78)=9.50, p=0.00). Also, the mean score varied statistically significantly (M=7.66, SD=2.63) of male students taught mensuration using the cooperative learning method and the mean score (M=8.73, SD=3.08) of female students taught mensuration without using the learning method of teaching (t (78) = 6.58, p=0.00). Therefore, cooperative learning in mathematics classrooms fosters students' ability to create and achieve learning objectives.

Authors: Salami Olajumoke Olayemi , Spangenberg Erica Dorethea
Published: June 2024

Playing mathematical games helps many senior secondary school students, especially girls, acquire basic mathematical skills. However, it can be difficult. Thus, this study examined how gender-related mathematical gameplay affects the performance of secondary school students. The study design was quasi-experimental. A sample of fifty senior secondary school students from the Federal Capital Territory (FCT) of Nigeria's Abuja Council Area was purposively chosen. The researcher randomly allocated intact classes to the experimental and control groups using a coin toss. The students' achievement level was determined by an algebraic achievement test administered before and after the treatment. T-tests, means, and standard deviation were used to analyse the data. The study revealed that female students had a higher mean score than male students when playing mathematics games. The findings imply that mathematical games enhance mathematics teaching and learning and should be encouraged and used by teachers to introduce concepts in mathematics to students, regardless of their gender, at different levels.
Is Mandatory Carbon Disclosure Associated With Real Carbon Performance: A Study of South African Companies Listed on JSE
Authors: NYAHUNA Thomas , DOORASAMY Mishelle , NOMLALA Bomi
Published: June 2024

With the increasing importance of carbon disclosure as a tool to reduce carbon emissions, the enduring question remains whether carbon disclosure reduces carbon emissions. This paper analyzes the rapport between "carbon disclosure and carbon performance" of 82 Johannesburg Stock Exchange (JSE) listed mining and manufacturing firms grounded on data released from 2010 to 2021. The environmental disclosure index is used in this study to quantify carbon disclosure, and the carbon intensity of the selected firms is used to gauge carbon performance. Using IBM SPSS Statistics 26, the study discovers that carbon disclosure (p< -0.023) is negatively associated with carbon performance. It means that an increase in carbon disclosure minimizes carbon performance.
Additionally, the study finds that carbon disclosure improves financial performance proxied by return on assets. The findings strongly support King Code III and IV's position that companies can improve environmental and financial performance by extensively disclosing environmental impacts. In this case, carbon disclosure can act as an instrument to improve corporate sustainability and counteract climate change. In line with the research results, it is recommended that policymakers in South Africa promote and adopt policies that compel and regulate companies to disclose their environmental impacts.

Published: June 2024

OJK surveys (2019 and 2022) show that the financial literacy index is lower than the financial inclusion index. The fact that the Financial Education Working Group has not carried out communication activities (diffusion) effectively. This study tries to see the innovation of communication activities from the Financial Education Working Group, as an agent of change in communication activities related to financial literacy to the community, so far. The Diffusion Theory of Innovation from Everett M. Rogers (1995) is used to explain the problem. The method using multiple case studies from Yin (2022) is qualitative descriptive. Interviews were conducted in ”snowball” manner to members of the Financial Education Working Group and the data were analyzed through the interactive model Miles & Huberman (2007). The results show that the relative advantage of diffusion innovation exists, but it is not too significant because of the lack of participation. Compatibility diffusion approaches differ from method to method and are only effective when tailored to the target or recipient of the information. In terms of complexity, the diffusion approaches used are relatively easy because they are often used in, such as,  seminars, workshops, counseling, or in the use of digital media. These diffusion approaches meet the element of trialability.observability; the diffusion approach used can be observed and results include, the number of participants, the enthusiasm of participants, the number of activities, and others.

Published: June 2024

In Ethiopia, barley and potato are the most important food security crop. Despite their  importance, the production and productivity of these crop are low due to several reasons. Potatoes and barley are growing alternatively in the study area year after year, and the area has the potential for bimodal rainfall distribution both in the short and main seasons. The short-season rain is suitable for potatoes, and the main season is for barley production. An evaluation of double cropping was tested to grow those crops in a double cropping system in Belge and in the main season in 2014. Based on the result of the evaluation and farmers' interest in the activities, the pre-scaling up of the barley-potato double cropping system was done in 2015, and 6-tone potato and 0.75-tone malt barely seed were used on three hectares of farmers land. Sample data were taken from both double and comparable farmer's fields of single cropping systems to show the yield advantage of double cropping compared with a single production system. An average of 46.4 t/ha of potato and 3.6 t/ha of malt barley yield from double cropping and 3.2t/ha of malt barely from single cropping were obtained during the main season. The net benefits of double cropping in monetary value were found to be 197,244.36 Ethiopian Birr. To sustain and strengthen the seed production and marketing of potato and barely double cropping technologies, training, experience sharing, and supply of early-generation seed for cooperatives are recommended as intervention options for sustainable production.
The Corporate Governance of South African State-Owned Enterprises (SOEs): Leadership and Compliance Issues
Authors: PETERSEN Robin , DUBIHLELA Jobo , CHAKABVA Oscar
Published: June 2024

The financial, operational, and business issues facing SOEs have reduced the trust that investors and citizens have in the state's capacity to effectively promote national economic growth. Most countries, especially developing ones like South Africa, have been plagued by the issue of inadequate public service delivery. One key contributing factor to this problem has been identified as the poor governance practices of SOEs. The magnitude of these massive SOE business failures, which surpassed the failure of numerous other enterprises around the world, drew attention to the urgent need for new corporate governance studies. To contribute to this, the study explores the corporate governance of South African SOEs, with a focus on leadership and compliance. To achieve this, an online questionnaire was used to gather quantitative data from a sample of 288 internal audit professionals. The data collected was then analyzed using SPSS software, and descriptive statistics were employed to present the findings. The study found that corporate governance malpractices are common in SOEs, which include hiring managers and executives who lack the necessary qualifications and experience, high tender irregularities, and understaffing critical duties.  This study is unique in that it employs stakeholder theory in an innovative approach to explain the findings, notably on the leadership issue. Besides, it contains critical recommendations for SOE leadership and policymakers on how to improve the corporate governance of SOEs to help them achieve their strategic goals, while also suggesting future study directions.

Published: June 2024

Giant planets exhibit diverse orbital properties, hinting at their distinct formation and dynamic histories. In this paper, using Gaia Data Release 3 (DR3), we investigate if and how the orbital properties of Jupiters are linked to their host star properties, particularly their metallicity and age. We obtain metallicities for main-sequence stars of spectral type F, G, and K, hosting hot, warm, and cold Jupiters with varying eccentricities. We compute the velocity dispersions of the host stars of these three groups using kinematic information from Gaia DR3 and obtain average ages using a velocity dispersion–age relation. We find that the host stars of hot Jupiters are relatively metal rich ([Fe/H] = 0.18 ± 0.13) and young (median age of 3.97 ± 0.51 Gyr) compared to the host stars of cold Jupiters in nearly circular orbits, which are relatively metal poor (0.03 ± 0.18) and older (median age of 6.07 ± 0.79 Gyr). The host stars of cold Jupiters in high-eccentricity orbits, on the other hand, show metallicities similar to those of the hosts of hot Jupiters, but are older, on average (median age of 6.25 ± 0.92 Gyr). The similarity in metallicity between the hosts of hot Jupiters and the hosts of cold Jupiters in high-eccentricity orbits supports high-eccentricity migration as the potential origin of hot Jupiters, with the latter serving as the progenitors of hot Jupiters. However, the average age difference between them suggests that the older hot Jupiters may have been engulfed by their host star over timescales ∼ 6 Gyr. This allows us to estimate the value of stellar tidal quality factor,

The growing number of Milky Way satellites detected in recent years has introduced a new focus for stellar abundance analysis. Abundances of stars in satellites have been used to probe the nature of these systems and their chemical evolution. However, for most satellites, only centrally located stars have been examined. This paper presents an analysis of three stars in the Tucana V system, one in the inner region and two at ∼10′ (7–10 half-light radii) from the center. We find a remarkable chemical diversity between the stars. One star exhibits enhancements in rapid neutron-capture elements (an r-I star), and another is highly enhanced in C, N, and O but with low neutron-capture abundances (a CEMP-no star). The metallicities of the stars analyzed span more than 1 dex from [Fe/H] = −3.55 to −2.46. This, combined with a large abundance range of other elements like Ca, Sc, and Ni, confirms that Tuc V is an ultrafaint dwarf (UFD) galaxy. The variation in abundances, highlighted by [Mg/Ca] ratios ranging from +0.89 to −0.75, among the stars demonstrates that the chemical enrichment history of Tuc V was very inhomogeneous. Tuc V is only the second UFD galaxy in which stars located at large distances from the galactic center have been analyzed, along with Tucana II. The chemical diversity seen in these two galaxies, driven by the composition of the noncentral member stars, suggests that distant member stars are important to include when classifying faint satellites and that these systems may have experienced more complex chemical enrichment histories than previously anticipated.

Research has shown that many young and intermediate-age clusters (younger than ∼2 Gyr) have extended main sequences and extended main-sequence turnoffs (eMSTOs), which cannot be adequately described by a single isochrone. The reason for the extended main sequences is now known, with the most probable cause being the fast rotation of stars. However, a significant fraction of slowly rotating stars form a younger stellar population than their fast-rotating counterparts, leading to speculation that they have undergone rotational mixing processes internally. One speculation is that a considerable number of slowly rotating stars reside in close binary systems, where tidal forces from companion stars are the cause of their rotational deceleration. In this work, we report a relatively old open star cluster in the Milky Way, NGC 2423 (∼1 Gyr old), which exhibits an apparent eMSTO. As anticipated, many characteristics of NGC 2423 indicate that its eMSTO is driven by stellar rotations. Our calculations indicate that if slowly rotating stars commonly have a close companion star, they should exhibit significant differences in radial velocities observationally, and binary systems that can be tidally locked within the age of NGC 2423 should have a mass ratio close to 1. However, none of these predictions align with our observations. Interestingly, among the only two equal-mass binary systems in the observed region for which spectroscopic data could be obtained, we discovered that one of them is a tidally locked binary system. This further suggests the validity of our numerical simulation results.

⊙), using high-resolution (0.″1; 0.8 kpc) Atacama Large Millimeter/submillimeter Array (ALMA) and multiwavelength JWST images from the COSMOS-Web program. Dissimilar to Hubble Space Telescope (HST) ACS images in the rest-frame UV, the redder NIRCam and MIRI images reveal a smooth central mass concentration and spiral-like features, atypical for such an intense starburst. Through dynamical modeling of the CO (J = 5–4) emission with ALMA, PACS-819 is rotation dominated and thus consistent with having a disk-like nature. However, kinematic anomalies in CO and asymmetric features in the bluer JWST bands (e.g., F150W) support a more disturbed nature likely due to interactions. The JWST imaging further enables us to map the distribution of stellar mass and dust attenuation, thus clarifying the relationships between different structural components not discernible in the previous HST images. The CO (J = 5–4) and far-infrared dust continuum emission are cospatial with a heavily obscured starbursting core (<1 kpc) that is partially surrounded by much less obscured star-forming structures including a prominent arc, possibly a tidally distorted dwarf galaxy, and a massive clump (detected in CO), likely a recently accreted low-mass satellite. With spatially resolved maps, we find a high molecular gas fraction in the central area reaching ∼3 (M

*) and short depletion times (M
gas/SFR ∼ 120 Myr, where SFR is star formation rate) across the entire system. These observations provide insights into the complex nature of starbursts in the distant Universe and underscore the wealth of complementary information from high-resolution observations with both ALMA and JWST.

The existence of a secondary (in addition to compact object mergers) source of heavy element (r-process) nucleosynthesis, the core-collapse of rapidly rotating and highly magnetized massive stars, has been suggested by both simulations and indirect observational evidence. Here, we probe a predicted signature of r-process enrichment, a late-time (≳40 days post-burst) distinct red color, in observations of gamma-ray burst supernovae (GRB-SNe), which are linked to these massive star progenitors. We present optical to near-IR color measurements of four GRB-SNe at z ≲ 0.4, extending out to >500 days post-burst, obtained with the Hubble Space Telescope and large-aperture ground-based telescopes. Comparison of our observations to models indicates that GRBs 030329, 100316D, and 130427A are consistent with both no enrichment and producing 0.01–0.15 M

⊙. Taken together the sample of GRB-SNe indicates color diversity at late times. Our derived yields from GRB-SNe may be underestimated due to r-process material hidden in the SN ejecta (potentially due to low mixing fractions) or the limits of current models in measuring r-process mass. We conclude with recommendations for future search strategies to observe and probe the full distribution of r-process produced by GRB-SNe.
A Quantification of the Effects Using Different Stellar-population Synthesis Models for Epoch of Reionization

The luminosity and spectral energy distribution of high-z galaxies are sensitive to the stellar-population synthesis (SPS) models. In this paper, we study the effects of different SPS models on the measurements of high-z galaxies and the budget of ionizing photons during the epoch of reionization by employing each of them in the semianalytical galaxy formation model L-Galaxies 2020. We find that the different SPS models lead to ≲0.5 dex differences on the amplitudes of UV luminosity functions, while two modes of the same SPS model with and without the inclusion of binary stars lead to similar UV luminosity functions at z ≥ 6. Instead, the binary stars produce ∼40% more ionizing photons than the single stars, while such differences are smaller than those caused by different SPS models; for example, the BPASS model produces ∼100% more ionizing photons than other models.
