Tabuleiro didático no ensino do Bioma Caatinga: O lúdico como ferramenta no processo de ensino-aprendizagem
Authors: Laurenço de Sousa Rosa Aparecida , Sampaio Diogo Ivan Jeferson
Published: August 2024

O bioma Caatinga, localizado na região semiárida do Brasil, é o único originalmente brasileiro e apresenta uma heterogeneidade nas suas paisagens, contribuindo deste modo para biodiversidade local. Entretanto, a Caatinga é uma das regiões menos valorizadas e protegidas, a qual, infelizmente, passa por um elevado grau de devastação e exploração devido, sobretudo ao uso irregular de seus recursos naturais. Neste contexto, é de extrema importância o papel da escola no desenvolvimento de estratégias que estimulem os alunos a valorizar e conservar a Caatinga a partir do ensino desse bioma nas aulas de Ciências no ensino fundamental e médio. O presente trabalho tem como objetivo avaliar a utilização de um tabuleiro didático no ensino da Caatinga. A pesquisa foi desenvolvida com alunos do 6° ano do ensino fundamental II da Escola Municipal Carlos Alberto M. D. Sobreira, localizada no município de Princesa Isabel, na Paraíba. Para tanto, realizou-se um estudo de natureza qualitativa, exploratória e descritiva, dividido em três momentos: 1) visita à comunidade escolar, estabelecendo agendamento para os próximos encontros; 2) construção do tabuleiro junto aos alunos em sala de aula; 3) aplicação do jogo resultando na prática pedagógica, onde houve o acompanhamento e observação da vivência em sala de aula. De modo geral, os alunos apresentaram pouco conhecimento sobre as características, biodiversidade e conservação do bioma Caatinga. Mesmo assim, ao longo das atividades, ocorreu um envolvimento e entusiasmo do alunado pela temática trabalhada, os quais participaram da construção do tabuleiro, tiraram dúvidas, trouxeram curiosidades, demostrando assim que estavam interessados e aprendendo o assunto de forma leve e por meio da socialização. Portanto, é possível dizer que o desenvolvimento de práticas pedagógicas como um jogo de tabuleiro pode abordar diversos temas e contribuir para uma aprendizagem significativa dos alunos. Ao mesmo tempo, estimulando o protagonismo dos discentes, o diálogo e a valorização do bioma que estão inseridos.

Published: August 2024

This study investigated the integrated valorization of defatted rice bran (DRB) by converting it into lactic acid (LA) and subsequently utilizing the residues from LA production for biomethane generation through anaerobic digestion (AD). Processing 480 kg of DRB resulted in the production of 70 L of pure LA and generated significant waste streams, primarily consisting of 572 kg of decanted hydrolysate pellet (Pellet DEC) and 220 kg of microfiltration retentate (Retentate MF). Exceptionally high methane yields of 374‒434 LN kgVS-1 were observed for residues from LA fermentation in biochemical methane potential tests, indicating their high potential for biogas production. During long-term semi-continuous AD, varying organic loading rates (OLRs) from 0.5‒2.5 kgVS m-3 d⁻¹ demonstrated feedstock- and OLR-dependent methane production. Reactor failure at higher OLRs was attributed to the accumulation of total ammoniacal nitrogen (TAN). The co-digestion of Pellet DEC and Retentate MF proved to be more resilient, with OLRs up to 2 kgVS m-3 d-1, mitigating TAN inhibition. Methane yields, ranging from 265‒334 LN kgVS-1 before reaching inhibitory OLR levels, were higher than those found in the literature. Process integration has emerged as a promising approach because the biogas generated from residues could effectively offset the energy demands of LA production. Supported by life cycle assessment, the integrated processes showed a 67% lower environmental impact at the midpoint and a 71% lower environmental impact at the endpoint, along with an 80% reduction in energy costs compared to the standalone LA production. Results proved a significant enhancement of the sustainability and economic viability of this integrated biorefinery approach.

Published: August 2024

We explore here, through reactive force field (ReaxFF) molecular dynamics simulations, oleic acid upgrading on beta zeolite (BEA) regulated with nine silica-to-aluminium ratios (SARs) to investigate their acid-catalyzed deoxygenation and coking susceptibility. The selected computational descriptors involved conversion, hydrodeoxygenation, and decarboxylation/decarbonylation selectivity, biofuels yield, and coke deposition characteristics. Simulations were validated by 20.3 SAR available experimental data and used for the systematic study. High deoxygenation selectivity was found to be related to the structural sensitivity of BEA(100) on the upgrading mechanism. ReaxFF simulations revealed that altering the Al-substitution could greatly promote biofuel formation. Specifically, SARs towards the mid-region (SAR 47) favored gasoline production, while 31 SAR exploited diesel-like hydrocarbons. An optimum ratio of 37.4 SAR achieved maximum oleic acid conversion (69.8%), with high yields of gasoline and diesel fuels (15.6 and 20.4 wt%, respectively) and moderate coking (8.6 wt%). Density functional theory screening of metallic dopants allowed investigating of their deoxygenation and coke susceptibility, obtaining that Cu-BEA structure favored the optimal carbon and O-moiety adsorption (-3.89 and -1.8 eV, respectively). Furthermore, the economic and environmental analysis showed that Cu-dopped BEA displayed the lowest market price and global warming potential (71 USD/kg and 2.8 kg CO2-eq/kg).

Does the 2030 agenda generate happiness? A longitudinal approach to the SDGs vs. the well-being of the world
Authors: Jose Arana-Barbier Pablo
Published: August 2024

This research aims to determine the relationship between the SDGs and the happiness of people in 40 developed and 114 developing countries since the 2030 Agenda initiative was implemented back in 2015. No literature measures such an  impact and it is essential to start the debate on the matter. This study determined that the relationship between the SDGs and the world’s happiness among the time horizons analyzed (2015-2021) is negligible through a set of panel data and multiple linear regressions.  There is much greater structural happiness that comes from sources other than the 2030 agenda. However, although most of these relationships are negative, the classification of the statistically significant SDGs into Maslow’s pyramid offers a novel view that allows prioritizing taking actions first on those SDGs associated with the most basic needs of people. This  study offers opportunities for future research into why an initiative such as the 2030 Agenda which seeks to generate well-being has the opposite effect and proposes that the initiatives associated with the 2030 Agenda be first linked to the SDGs at the bottom of Maslow's pyramid  and that they progressively ascend as positive correlations are achieved between the SDGs and people's well-being.

Sorghum is one of the most important and under-utilized cereal crops in the Arid and Semi-Arid land (ASAL) regions of Kenya. The crop is grown in drought-prone marginal agricultural areas of Western Central and Eastern and coastal regions of Kenya. The diverse biotic and abiotic constraints including climate changes reduce sorghum productivity. Sorghum technology generators continue promoting suitable management practices and innovations to cushion and improve the resilience of smallholder farmers against the adverse effects of climate change. These interventions contribute to the attainment of not only household and national food security but also enhance incomes. Despite the increasing sorghum production and utilization in West Pokot County, there is limited knowledge of the status of production, processing, and utilization technologies. The aim of this study was to assess the current sorghum production, processing, utilization technology, innovations, and management practices among smallholder farmers. A household survey was undertaken using a jointly developed structured questionnaire by a multi- and inter-disciplinary team of researchers. Using a multi-stage sampling technique, 599 households were randomly selected and interviewed. Data collected were on household and farm characteristics including technologies. The study revealed that compared to maize and pasture, land allocated to sorghum enterprise was relatively low ranging from 0.32 acres to 0.80 acres with an average of 0.73 acres. The adoption of various sorghum technological components was also low. Adoption of improved sorghum varieties was less than 7% while fertilizer use was less than 20%. These contribute to low crop yields of about 140kg per acre. In addition, value addition was also low. Sorghum use was limited to ugali (56%) and porridge (39%) against the diverse value-added products including bread baking. and industrial processing of pure and blended products. More farmer and stakeholders training need to be done. In order to fully upgrade the sorghum value chain; there is the need to have targeted sorghum policies focusing on a range of activities along the value chain. These interventions could be integrated into the West Pokot County Integrated Development Plan. Key words: Sorghum, Production, Marketing, Utilization, Challenges, Opportunities, West Pokot

In line with the sustainable development goal to end poverty in all forms, the Nigerian Government launched Government Enterprise and Empowerment Programme (GEEP) - as a social investment programme to alleviate poverty by providing credit to petty traders to support entrepreneurship. This study assesses the impact of Government Enterprise and Empowerment Programme (GEEP) on the poverty status of beneficiaries in Cross River State, Nigeria. Specifically, it compared the mean income before, and after accessing the loan, analysed the determinants of poverty status of the respondents in the study area, enumerated the benefits of GEEP to the respondents, and identified the challenges faced by the beneficiaries in accessing the loan. Stratified random sampling technique was used to select 398 respondents who had benefitted from the programme across the eleven Local Government Areas (LGAs) that the programme covered. Data were obtained from primary source with the aid of a well-structured questionnaire, and analyzed using; frequency count, mean, Foster Greer and Thorbecke (FGT) model, paired T- test (Z), and logistic regression analysis. The results showed that, majority of the respondents were male (55.6%) with a mean age of 35 years, and had an average household size of 5 persons. The study also showed that 98.9% of the respondents were educated. The mean monthly income before GEEP support was N 44,535.53, while after GEEP it was N54180.20. Thirty-six percent of the total respondents were poor (36%). The comparative analysis of the mean income before and after accessing the loan showed that, there was a significant difference between their mean incomes at 5% level of significance. Key variables that determined poverty status were; household size and loan amount. The main benefits of GEEP to the respondents were; increase in beneficiaries’ income, and improvement in their standard of living. The major challenges faced by the respondents were; lack of appropriate means to repay loan, stressful loan procedure, and difficulty in transferring money from mobile wallet to bank. The study recommended that the loan application process should be less complex to enable quick loan application. The GEEP programme should be sustained, and allowed to have wider coverage in both rural and urban areas of the country as it has assisted a lot of small business owners’ access to cheap credit.

Black glutinous rice flour (BGRF) had the potential to be used as a wheat substitute to increase the health-promoting nutritional value of pasta products. The purpose of this study was to investigate the possibility of using BGRF as an alternative to wheat flour in the production of pasta to improve its nutritional value. The research explored the physical, chemical, sensory properties, and consumer acceptance of pasta formulations with 0%, 20%, 40%, and 60% BGRF substitution. The findings revealed that pigmentation of BGRF contributed to increased phenolic compounds and antioxidant properties, which impacted physical and chemical properties of the pasta. The results indicated that a 40% substitution of BGRF was well-liked by consumers, while a 60% substitution led to decreased acceptance. The physical properties of uncooked pasta (UC-PAS) and cooked pasta (CK-PAS), such as moisture content and color values, were significantly influenced by the percentage of BGRF substitution. Specifically, the moisture content of UC-PAS decreased with higher BGRF substitution, resulting in changes in color values. These changes included an increase in redness, as well as a decrease in lightness and yellowness. Additionally, the pigmentation of BGRF contributed to increased phenolic compounds and antioxidant properties, which affected physical and chemical properties of the pasta. The pasta’s cooking quality, including cooking time (CKT), cooking loss (CKL), and cooking yield (CKY), also showed significant differences with varying percentages of BGRF substitution. Furthermore, the proximate composition indicated that the percentages of ash, protein, fat, and fiber increased as the proportion of BGRF increased, with pasta containing 60% BGRF demonstrating the highest values for these properties. All these findings provide evidence that BGRF substitution had a significant positive impact on the physical, chemical, and sensory properties of pasta. For example, the pasta had better antioxidant properties and was well-accepted by consumers. The potential for enhancing the nutritional profile of pasta products by substituting wheat flour with BGRF is noteworthy.

Optimal nutritional status is crucial for enhancing the physical fitness components of amateur basketball players as it directly influences their strength, endurance, and overall performance. This study assessed the effect of nutritional status on the performance components of physical fitness of amateur basketball players in Makurdi, Benue State, Nigeria. This was a cross-sectional ex post facto study. Participants were 80 (40 male and 40 female) secondary school basketball players from a population of 160 (80 males (8 teams) and 80 females (8 teams) who were selected using random sampling technique from 16 registered teams from the 2023 Benue State Secondary School Basketball League organized by the Benue State Sports Council, Makurdi. All the participants underwent nutritional assessment based on WHO standards. The participants’ height and weight were measured in accordance with the protocol of ISAK. The Slalom test was performed to evaluate agility. The Harre circuit test (HCT) was used to assess coordination. Speed was assessed using the 50m dash. Reaction time was assessed using the reaction time ruler drop test. In all the tests, those with lower time were considered to be more fit and vice versa. Mean and standard deviation were computed for the performance of the participants in agility, coordination, speed and reaction time. The participants were split into three in relation to nutritional status (normal, thin/wasted and stunted). The analysis of variance was used to find out the different performance components of adolescents in relation to nutritional status. All the analyses were performed on 95% confidence intervals using the statistical package for social sciences (SPSS v21). The result of the study indicated that nutrition has significant effects on agility (F=10.495, df=2, 77; p<0.05), coordination (F=17.750, df=2, 77; p<0.05), speed (F=5.908, df=2, 77; p<0.05) and reaction time (p<0.05) of amateur basketball players in Makurdi. It was concluded that nutritional status has a significant effect on several key performance components of physical fitness among amateur basketball players in Makurdi, Benue State, Nigeria. It was recommended among others that coaches should take the nutritional status of their players as important as other parameters to ensure a better performance of their players in basketball.

A Plein Air Painting Event as a Liminal Experience Building the Artists’ Community
Authors: Sulikowska-Dejena Agata
Published: August 2024

The subject of the article is a plein air painting event, considered as a liminal experience that is widely practiced by traditional artists to create and maintain communities in the local and supra-local art fields. The interest in organizing this kind of meetings among artists, modern art galleries, and art schools is not decreasing, and one can talk about the exceptionally long duration of the phenomenon. This article discusses the experience of participants for whom these joint meetings have a metaphysical dimension. The descriptions and expressions used by the artists have become the inspiration to use Victor W. Turner’s concept in the analysis. That is why this practice is discussed as a liminal experience and a rite of passage, whereas the relations between its participants are understood in terms of a specific type of community that is called by Turner ‘spontaneous communitas’. All the considerations and conclusions included in this text are based on qualitative research conducted among visual artists.

Published: August 2024

In this article I analyze the actions of the Interdisciplinary Creative Research Center “Pracownia” using the author’s art-based research typology of six moves: downward (two types), upward, inward, along, and across. The paper considers culture animation/community arts to be practices of researching oneself and the world through art. I explain this via the example of “Pracownia” and select one photo of their actions from the years 1978–1981 in order to present every point of the typology. The research aims to fill in the gaps in the history of Polish community arts/culture animation, whilst providing analytical tools for social scientists and practical guidelines for culture animators/community artists.
New Roles, Old Rituals: The Mobilization of the Listener Community Based on the Example of Radio 357
Authors: Chmielewski Piotr
Published: August 2024

This article analyzes the community of patrons of the Internet radio station Radio 357, based on 13 in-depth interviews with the station’s listeners and a former station employee. Material from the online forum of the studied community is also analyzed. The text aims to present the members of a radio community who became involved in financing a new Internet radio station through online fundraising. An attempt is made to explain the listeners’ motivations for their unique scale of involvement in this new media initiative. The research questions relate to the characteristics of the Radio 357 audience community and the role that radio plays for them. The foundations built by many years of participation around the former station and the sense of injustice intensified by its symbolic collapse became the driving forces to fight for the continuation of their previously cultivated radio practices and traditions, already incorporated within the new station.
The Impact of Transportation on The Avocado Market in Tanzania
Authors: Tumaini Steven , Ghahula Raphael , Macha Salvio
Published: August 2024

Avocado (Persea americana) is grown in many nations throughout Africa, Asia, Europe, and South America. The climate of Tanzania offers a perfect habitat for growing avocados. This paper investigates how transportation affects the Tanzanian avocado industry. Data were gathered from 505 farmers and 37 categories/groups using a cross-sectional design. Data analysis was done using SPSS where descriptive statistics and the chi-square test.  A one-way analysis of variance (ANOVA) with Tukey's Honest Significant Difference (HSD) test at p < 0.05 was also done. According to the results, local avocado output is dominated by men (79% male vs. 21% female). The result of the binary logit model revealed that the participation of avocado producers in a high-value market was influenced by age, educational status, the number of avocados sold, the price of avocado, and market information. With sorting (12%), grading (7%), and packaging (9%), quality during production was judged most important (25%), followed by harvesting (16%), storage (16%), and transportation (15%) with less relevance were factors impacting quality. Improving the avocado market for growers depends on addressing these problems at the national, regional, and district levels. Hence, transportation has a big influence on the avocado industry since smallholder growers have great difficulties influencing market access and produce quality. Improvement of transport infrastructure and support systems at the national, regional, and district levels will help to boost the avocado market.

Cet article présente un modèle d’autoévaluation et d’accompagnement des acteurs dans les établissements scolaires en mettant l’accent sur les indices de sa référence humaine. L’objectif de ce travail est de présenter un dispositif intégré d’évaluation/accompagnement et  d’expliquer une partie de sa mise en œuvre relative au suivi de la pratique enseignante. Notre hypothèse est qu’un ensemble de synergies au sein de chaque processus à part, celui de l’évaluation et celui de l’accompagnement et surtout des  articulations centrales entre ces deux processus forment la source qui nourrit la visée humaine de la gouvernance interne de l’établissement. En se basant sur un dispositif qui se compose d’une matrice évaluative et d’un ensemble d’instruments d’observation et de mesure des performances, l’expérience mené au sein d’un groupe scolaire d’ enseignement privé  consistait à intégrer les enseignants, acteurs principaux de notre recherche-action, dans la mise en œuvre de l’évaluation et à les accompagner en même temps pour développer leur pratiques. A mi-parcours de ce projet, nous avons conclu que les enseignants ont pu jouer  le rôle d’évaluateur-acteur et ont réussi à travers leurs participation réflexive et active à développer leurs projets professionnels et à concrétiser les actions du projet de l’établissement.
 
This article presents a model for self-evaluation and support of actors in schools, focusing on the indicators of its human reference. The aim of this work is to present an integrated assessment/support system and to explain part of its implementation relating to the monitoring of teaching practice. Our hypothesis is that a set of synergies within each separate process, that of assessment and that of support, and above all the central links between these two processes, form the source that feeds the human dimension of the school's internal governance. Based on a system consisting of an evaluation matrix and a set of instruments for observing and measuring performance, the experiment conducted within a private school group involved integrating the teachers, the main actors in our action research, into the implementation of the evaluation and at the same time supporting them in developing their practices. Halfway through the project, we concluded that the teachers had been able to play the role of evaluator-actor and had succeeded, through their reflective and active participation, in developing their professional projects and putting into practice the actions in the school's project.

Ce travail consiste à analyser les phénomènes hydrologiques et hydrauliques du bassin versant d’assainissement urbain du quartier Adidoadin de la Commune Golfe 5 à Lomé, au Togo. Il a pour objectif  d’identifier les causes des inondations de ce bassin versant d’assainissement urbain. La méthode de Manning-Strickler a été utilisée pour évaluer le débit d’écoulement d’eau dans les collecteurs et la méthode rationnelle a servi pour la détermination du débit généré par la pluie sur le bassin versant étudié. À travers une combinaison de techniques hydrologiques et hydrauliques de l’étude de cas réalisé pour la vérification de la capacité  des collecteurs d’évacuateurs de crues, avec un débit de 3,76 m3/s, a montré que ce débit est supérieur au débit d’eau provenant du bassin versant (0,774m3/s), même avec un coefficient de ruissellement le plus défavorable (0,9). A cet effet, les problèmes d’inondation seraient dus à la présence de crêtes qui ne favorisent pas l’écoulement gravitaire, également des conséquences issues d'une urbanisation mal maîtrisée (défaut de conception des infrastructures, extension de nouveaux quartiers dans des zones à risques). Ainsi, Cette recherche examine les caractéristiques physiques du bassin versant, évalue les régimes de précipitations et de ruissellement, identifie les problèmes d'inondations dûs aux changements climatiques et propose des mesures d'atténuation appropriées pour minimiser les risques d'inondations et d'érosion, tout en favorisant une utilisation efficace des ressources en eau.
This work involves analyzing the hydrological and hydraulic phenomena of the urban drainage catchment area of the Adidoadin district of Commune Golfe 5 in Lomé, Togo. The aim of this study is to identify the causes of floods in this urban drainage watershed. The Manning-Strickler method was used to assess the flow of water in the collectors and the rational method was used to determine the flow generated by rainfall in the catchment area studied. The use of a combination of hydrological and hydraulic techniques to verify the hydraulic capacity of the spillway collectors, with a flow of 3.76 m3/s of the studied case, showed that this flow is greater than the flow of water coming from the catchment area (0.774m3/s), even with the most unfavourable runoff coefficient (0.9). Flooding problems are thus due to the presence of ridges that do not favor gravity flow, and to the consequences of poorly controlled urban development (faulty infrastructure design, extension of new districts into at-risk areas). Henceforth, this research examines the physical characteristics of the catchment, assesses rainfall and runoff patterns, identifies flooding problems due to climate change, and proposes appropriate mitigation measures to minimise the risk of flooding and erosion, while promoting the efficient use of water resources.
Parallel implementation for real-time visual SLAM systems based on heterogeneous computing

Published: August 2024

Simultaneous localization and mapping has become rapidly developed and plays an indispensable role in intelligent vehicles. However, many state-of-the-art visual simultaneous localization and mapping (VSLAM) frameworks are very time-consuming both in front-end and back-end, especially for large-scale scenes. Nowadays, the increasingly popular use of graphics processors for general-purpose computing, and the progressively mature high-performance programming theory based on compute unified device architecture (CUDA) have given the possibility for large-scale VSLAM to solve the conflict between limited computing power and excessive computing tasks. The paper proposes a full-flow optimal parallelization scheme based on heterogeneous computing to speed up the time-consuming modules in VSLAM. Firstly, a parallel strategy for feature extraction and matching is designed to reduce the time consumption arising from multiple data transfers between devices. Secondly, a bundle adjustment method based solely on CUDA is developed. By fully optimizing memory scheduling and task allocation, a large increase in speed is achieved while maintaining accuracy. Besides, CUDA heterogeneous acceleration is fully utilized for tasks such as error computation and linear system construction in the VSLAM back-end to enhance the operation speed. Our proposed method is tested on numerous public datasets on both computer and embedded sides, respectively. A number of qualitative and quantitative experiments are performed to verify its superiority in terms of speed compared to other states-of-the-art.
