Authors: Candilasa Jahzeel M.
Published: January 2025

Referential questions are designed to elicit open-ended responses, allowing students to express their understanding in a way that is meaningful to them. This paper investigates the impact of the teachers' use of referential questions on the students' oral participation and academic performance in an English class. Using a quasi-experimental research design, the study investigated the Grade 10 students' level of oral involvement in terms of frequency and fluency. It used a researcher-made oral participation rubric and class records to gather the necessary data. The study's results revealed improved student oral participation after the teacher consistently used referential questions. Additionally, an increase in the student's grades in English was also seen in the class record after one grading period of using referential questions in the classroom. Finally, the statistical data showed a positive relationship between the students’ frequency of oral participation and academic performance in English but no direct correlation between the quality of their oral participation and their academic performance in English. This study recommends that teachers incorporate referential questions regularly in English classes to enhance students' oral participation and engagement.

Authors: OKHOTNIKOVA Olga Sergeyevna , DOROFEEV Alexey Evgenievich
Published: January 2025

The marathon, originating from the Greek ??????????, is a long-distance foot race covering 42.195 km, typically run on roads but also possible on trails. This study aimed to assess the level of awareness of marathon athletes about their own dental health. A survey was administered to 40 amateur athletes who engage in long-distance running and participate in marathons. These athletes had varying fitness levels and had been involved in distance running for over a year. Results indicated that the greatest influence on the oral hygiene of athletes was exerted by the amount of running performed per month. Increasing monthly running volume may have a negative impact on the oral hygiene scores of marathon athletes. Anthropometric data, as well as oral hygiene products and methods, were also considered. The study concludes that the influence of running volume per month on oral hygiene may be indirect for several reasons, suggesting a complex relationship between endurance running and dental health. This research highlights the need for further investigation into the specific mechanisms by which intensive physical activity might affect oral health in endurance athletes.

Authors: Rubashvili Imeda , Tsiklauri Aleksandre
Published: January 2025

This present work describes recovery studies for direct and indirect sampling methods in combination with microbiological enumeration test methods for bioburden determination on the shared manufacturing equipment surfaces in support of cleaning validation. The swab and rinse sampling methods were developed in order to obtain a suitable recovery (>35 %) for five challenge Gram-negative rod, Gram-positive cocci, yeast, mold and spore former microorganisms and three types of equipment material (plastic, glass, and stainless steel) in this study. The swabbing involved moistening the swab with sterile saline and swabbing the area (100 cm2) to be sampled in an overlapping zigzag pattern. Rinse sampling was performed using a separate sampling rinse with a fixed volume of water for injection from a piece of equipment. The swab and rinse samples were tested using the plate count and membrane filtration methods, respectively. The recovery rate is higher for the swab sampling method (60.5 %) compared to the rinsing method (46.8 %). The combination of the developed sampling and the microbiological enumeration test methods gives a good recovery (>36.17%) with high precision (RSD<19.25%). The proposed methodology can be used to perform cleaning validation successfully.

Authors: Lima Jacqueson Martins , Andrade Saulo Paschoaletto de , Ribeiro Sandro Pereira
Published: January 2025

This work aims to report on the transformation of waste cooking oil into biodiesel, soap, and bioplastic, which can enable the insertion of science themes from the National Curricular Base content in a transversal and interdisciplinary manner for students and teachers in basic education. In this context, through students and teachers of the Professional Master's in Environmental Sciences at Univassouras, teachers were trained to work practically with Chemistry contents as recommended by the National Curricular Guidelines and Parameters. The professional training was supported by didactic material (follow-up module) and enabled the adoption of practical classes with process innovation where recycling artifacts and equipment, called alternative materials, were developed. Discarded toy car motors were used as an agitation system for the waste oil, and PET bottles were used as decanters for separating glycerin and biofuel, pieces of PVC pipes and wood for supports, and household stoves and burners as heating systems. The results are being evaluated and inserted into a follow-up report and will be part of dissertations by Master's students.
FAST PYROLYSIS OF COCOA BEAN SHELL
Authors: VICHO Maria Milagros , TELLEZ Jhoan Francisco , MOYANO Elizabeth Laura
Published: January 2025

The increasing demand for sustainable waste utilization has led to growing interest in cocoa shells as a valuable biomass resource. This study investigates the pyrolysis of cocoa shells, both untreated and acid-treated, at temperatures of 300, 400, and 500°C to extract valuable compounds with potential commercial applications. Pyrolysis, a thermochemical decomposition process in the absence of oxygen, was carried out using nitrogen as the pyrolysis atmosphere to ensure optimal reaction conditions. The aim was to optimize the production of bio-oils enriched with value-added compounds, such as fatty acids (FA) and anhydrosugars. These pyrolytic oils were analyzed using gas chromatography-mass spectrometry (GC-MS), revealing significant amounts of fatty acids, including palmitic acid, cis-vaccenic acid, and stearic acid. Notably, acid-washed cocoa shells exhibited higher bio-oil yields compared to untreated samples, with 500°C being the optimal temperature, yielding the highest amount of bio-oil. Furthermore, this temperature favored the formation of specific compounds, enhancing the overall value of the pyrolytic products. Additionally, the pyrolysis of acid-treated biomass resulted in a high concentration of levoglucosan, a valuable anhydrosugar, which accounted for over 50% at 500°C. These findings suggest that the pyrolysis of cocoa shells, especially when pretreated with acid, not only provides an efficient method of waste valorization but also generates bio-oil and biochar with potential properties for health, energy production, and environmental applications. This research highlights the importance of exploring agricultural residues, such as cocoa shells, for sustainable bioresource development, contributing to a circular economy and reducing the environmental impact of agro-industrial waste.

Authors: OLMEDO Walter E. , ROSSA Maximiliano
Published: January 2025

Basic oxides play a crucial role in various industrial catalytic processes due to their ability to activate the O-H, C-H, and C-O bonds of simple alcohols on the M²?-O²? catalytic center, which consists of a Lewis acid and a Brønsted base. This study investigated the mechanisms at the molecular level of gas-phase reactions between methanol and cationic subnanometric barium-containing clusters, namely, Ba??, Ba(OH)?, and Ba(H?O)??, which are used as model systems for the active sites of heterogeneous basic oxide catalysts. The experiments were performed under thermalization conditions at 291.5 K on a new experimental setup based on a Smalley cluster source coupled to a fast flow reactor, which is enclosed in a molecular beam apparatus with time-of-flight mass spectrometry detection. Complementary theoretical calculations at the density functional theory level were carried out on the various relevant reactions to aid in the interpretation of the experiments. The joint experimental and theoretical results suggest that the adsorptive behavior of basic oxides like BaO towards methanol and water molecules can already be evidenced in these small clusters, reinforcing their role as potential active sites in heterogeneous basic catalysts.

Published: January 2025

In this work, we report a facile one-pot synthesis of silica nanoparticles (SiO2NPs) than the classical Stöber method, involving sodium metasilicate as a cheaper Si source than TEOS and shorter reaction times under neutral reaction conditions at room temperature. A multi-technical characterization of the SiO2NPs (XRD, FTIR, UV-vis DR,TEM, Z-potential, and N2 adsorption-desorption isotherms at 77 K) evidenced the formation of spherical NPs, with a polydisperse nature, negatively charged surface, and porous structure. A metric to assess the “greenness” of the proposed SiO2NPs synthesis allows to indicate that is a more environmentally friendly process than other chemical procedures, which was performed under mild conditions, such as room temperature and ambient pressure, without a derivatization process, using only water as solvent, and generating innocuous waste.

The present study investigated the effects of confinement on secondary biochemical and physiological stress responses in Nile tilapia (Oreochromis niloticus). Stress is a central issue in physiology due to its impact on animal health and life. In this study, 36 juvenile tilapia (n = 12/group) were divided into three groups: control (CT), confinement stress (EC), and confinement plus "aggression" stress (CA). The CT group was free from manipulation, while the EC group was confined for 30 minutes in a space representing 10% of the original tank volume. The CA group was confined under the same conditions and then subjected to the "mirror test" paradigm. This test is a stressor for the animal, as it simulates the presence of another fish through its reflection in the mirror, generally inducing stress by triggering aggressive-like behavior. After the experiments, blood was collected, and the following parameters were evaluated: ventilatory frequency (VF), blood glucose, hemoglobin, hematocrit, erythrocytes, hematimetric indices (VCM, HCM, and CHCM), and plasma proteins. Our results showed that only confinement combined with stress from the "mirror test" (CA group) significantly elevated FV and glucose levels compared to the CT group, and hemoglobin and plasma protein levels compared to the CT and EC groups (p < 0.05). These results suggest that confinement alone (for 30 minutes) is not sufficient to alter the biochemical and physiological parameters evaluated. Additionally, confinement in a restricted space may trigger an exaggerated biochemical and physiological response when the animal is subjected to another type of stressor. The study highlights the importance of strategies to mitigate the effects of stress, as it can cause various disorders that directly impact the animal's life.

Published: January 2025

The increase in greenhouse gas (GHG) emissions is a global concern due to its impact on climate change. To address this challenge, the development of corporate GHG inventories is crucial, enabling organizations to understand and mitigate their emissions. This study aims to statistically analyze whether there was a significant increase in GHG emissions over a 10-year period by organizations from various sectors of the economy that voluntarily published their inventories in the Brazilian GHG Protocol Program. Data were obtained from the inventories of 66 organizations that published at 2013 and 2022 in the Brazilian GHG Protocol Program. The data was processed and analyzed using Minitab software to determine the significance level of the increase in GHG emissions. A total increase of 159,264,734.26 tCO2e in GHG emissions was observed from 2013 to 2022, with 29 organizations reporting higher emissions and 37 showing reductions. However, statistical analysis demonstrated that there was no significant increase in GHG emissions over the study period. The results highlight the importance of organizations conducting their GHG inventories to enhance transparency and make strategic decisions aimed at mitigating their emissions. Publishing inventories allows for monitoring progress and identifying priority areas for effective interventions. No significant increase in GHG emissions was observed over the 10-year period; therefore, this study reinforces the importance of preparing GHG inventories by organizations. The findings can impact public policies on climate change, supporting the introduction of regulations that mandate the development of inventories and the setting of emission reduction and offsetting targets.

Published: January 2025

Anacardium occidentale, known as the cashew tree, is a plant native to Brazil, particularly abundant in the Northeast, which is responsible for 98% of the species' production. Cashew cultivation yields two main products: the nut, used for oil extraction and edible kernels, and the pseudofruit, which can be consumed directly or processed into various foods. After the pseudofruit is pulped, the remaining bagasse accounts for 15% of the mass and is a still underutilized residue, despite its rich composition, which includes tannins, carotenoids, cellulose, and pectin, as well as antioxidant properties. Due to global sustainability trends, cashew bagasse has gained prominence as a source of valuable compounds, especially polysaccharides. These biomaterials show promise in the pharmaceutical field, where they can be used as vectors for controlled drug release, given their biocompatibility and biodegradability. Such systems offer benefits such as the precise delivery of active substances, reduced doses and side effects, as well as potential for cell regeneration and the transport of growth factors.

Authors: LOPEZ Paula , LOPEZ Débora Natalia , SPELZINI Darío
Published: January 2025

With the increasing prevalence of obesity and non-communicable chronic diseases associated with sedentary lifestyles and high-calorie diets, interest in plant-based dietary approaches is growing. Emulsion gels (EG) made from plant ingredients present a promising alternative to animal fats. The characteristics of EG are influenced by the functional properties of the protein layer stabilizing the oil droplets, which can be affected by the drying method used to process the proteins. This study evaluated the rheological and textural properties of EG prepared with freeze-dried (FP) and spray-dried (SP) lentil proteins at different oil concentrations. Results showed that FP EG exhibited higher hardness values than SP EG at both oil fractions, with an increased hardness at 50% oil fraction. A gel-like structure was observed in all of the EG tested. These findings suggest that freeze drying could be a more suitable drying method for the development of EG, although further investigation is needed.

Authors: LIMA Sara da Silva , SILVA Francico Mayron de Sousa , VIANA Vicente Galber , CARVALHO Luiz Fernando Meneses , NUNES Livio Cesar Cunha
Published: January 2025

The annatto plant (Bixa orellana L.), from the Bixaceae family, is widely recognized as the source of the most used natural dye in the world. The extracts obtained from its fruits can be water-soluble or fat-soluble, positioning annatto as one of the main natural products for the food industry, besides its applications in pharmacology, cosmetics, and technology. Carotenoids extracted from annatto are vulnerable to degradation when exposed to light, high temperatures, or sulfur dioxide. This degradation can compromise the effectiveness of carotenoids, which demonstrate significant potential in clinical treatments. Bixin, one of the main compounds extracted from annatto seeds, can contribute to reducing cholesterol levels, preventing cardiovascular diseases, decreasing inflammation in lung injuries, influencing motor activity in mice, and inhibiting gastric secretion without impacting acid production. Additionally, bixin presents antispasmodic and hypotensive properties, potentially improving health and well-being, especially when applied in biomedical devices. The analysis of bixin by UV-visible spectroscopy, in the range of 200 to 900 nm, using chloroform as a solvent, indicated that the peaks observed in the spectrum vary according to the solvent used. Infrared spectroscopy revealed a band between 772.4 and 778.8 cm?¹, associated with hydrogen vibration of a cis-C-CH=CH-C structure, with a strong peak at 754 cm?¹. The presence of a peak at 1159 cm?¹ strongly suggests the cis structure of bixin. Future studies are fundamental to deepen the understanding of how these characteristics influence the efficacy and safety of bixin in specific applications.

BIOCOMPATIBLE GELATIN/CURCUMIN DRESSINGS FOR POTENTIAL USE IN ANTIMICROBIAL PHOTODYNAMIC THERAPY
Authors: STANLEY Milagros , CID Mariana , SALVATIERRA Nancy , TEMPESTI Tomas , COMIN Romina
Published: January 2025

Chronic wound infections caused by antibiotic-resistant bacteria have become a significant problem for modern healthcare systems, often associated with high costs and requiring intensive topical wound management. Successful wound healing is achieved by reducing bacterial load and providing an environment conducive to cell growth. Nanofibers demonstrate remarkable success in wound healing due to their structure, which offers a promising platform for drug delivery that can mimic the native extracellular matrix and accelerate cell proliferation. In this study, cytocompatible gelatin plus curcumin nanofibrous membranes were obtained by electrospinning. The combination of these nanofibers with antimicrobial photodynamic therapy, a promising procedure that does not induce antibiotic resistance, aims to enhance the antimicrobial effect through the activation of curcumin. The membranes were crosslinked with glutaraldehyde vapors to improve their stability in aqueous media. The hydrophilicity of the membranes were determined by measuring the water contact angle, and cytotoxicity was evaluated. Smooth and homogeneous nanofibers formed gelatin/curcumin membranes. The addition of curcumin did not decrease membrane hydrophilicity, which exhibited good cytocompatibility to Vero cells. These results demonstrate the potential of gelatin/curcumin nanofibrous membranes as a promising strategy in antimicrobial photodynamic therapy, providing a valuable option for controlling bacterial infections and antibiotic resistance.

Authors: CARDOSO Rafael , ARAÚJO Marco Antonio Pereira
Published: January 2025

Over the last two centuries, the relationship between man and the environment has intensified, resulting in a negative deficit that has been seen to the detriment of our planet. This has led to the high consumption of renewable and non-renewable natural resources, in addition to the impacts generated by population growth and the increased demand for subsistence in societies, which has led to a major imbalance in observed natural phenomena. Studies and reports have shown how climate and environmental changes, directly and indirectly, interfere with production systems, especially food systems, causing the environmental decharacterization of food production sites, forcing them to migrate in search of areas with better environmental and climate quality. Furthermore, it is increasingly observed that environmental changes cause major problems in the nutritional composition of food, impacting the Food and Nutrition Security of several countries and, as a consequence, impacting the health quality of these societies.

Drinking quality water is a fundamental human right, although many individuals still lack access to this resource due to several factors. One major factor is the inadequate disposal of domestic and industrial sewage, as well as the storage of industrial solid waste along riverbanks, which contaminates the soil and water with heavy metals and other emerging pollutants. This is particularly evident in the Paraíba do Sul River (RPS) in the city of Volta Redonda, Rio de Janeiro, Southeastern Brazil. This study aims to assess ore processing waste impacts present on RPS banks on this river’s waters. A quantitative methodology was employed by analyzing water samples with an atomic absorption spectrophotometer (AAS) to quantify metal concentrations in RPS water samples in accordance with current Brazilian legislation (CONAMA 357/2005).

A study at the Department of Agronomy, University of Ilorin, Nigeria examined the effect of bulk density and organic amendment on soil properties and cowpea yield using a two factorial Randomized Complete Block Design. Treatments included six levels of imposed bulk density (1.0, 1.20, 1.40, 1.60, 1.80 and 2.0 g×cm-3) and two types of organic amendments (poultry droppings and cattle dung), applied at 10% per pot, with an un-amended control, replicated twice. The experiment was conducted twice during 2023. Parameters measured included total porosity, organic matter content, germination percentage, and yield. As soil bulk density increased from 1.2 to 2.0 g×cm-3, total porosity declined by at least 7% for every 0.2 g×cm-3 increase; however, organic amendment significantly increased porosity by 18%. Increasing bulk density from 1.4 to 2.0 g×cm-3 reduced soil organic matter. Soil reaction changed significantly only at 2.0 g×cm-3 bulk density. Bulk density beyond 1.40 g×cm-3 significantly reduced cowpea germination by 10-28%. Bulk density from 1.40 to 2.0 g×cm-3 reduced cowpea yields by 16% per 0.2 g×cm-3 increase, with 1.40 g×cm-3 established as critical bulk density. Organic amendment significantly doubled cowpea yield, with no significant difference between poultry droppings and cattle dung effects.

Ecosystems are complex systems characterized by intense interactions and material exchanges, driven by high energy flows. Understanding how these networks function, including their inputs and outputs, is essential for more effective protection of natural ecosystems and for applying the concept of sustainability to human activities. Ecosystems, as bounded systems, are defined by their energy exchanges with external systems and their internal dynamics. This review explores the relationship between ecosystem services and energy flows, focusing on how the quality and quantity of inputs influence system development. Emergy, a tool to assess the convergence of matter and energy within systems, is measured in solar emergy joules (seJ) and represents the work performed by nature to provide services. On the other hand, the ecosystem services approach, increasingly used in environmental policies, quantifies ecosystem outputs through an anthropocentric perspective. The analysis reveals that various methodologies, including eco-exergy and emergy analysis, offer complementary ways to characterize the state and function of ecosystems. These approaches provide valuable insights by integrating both the internal organization of ecosystems and the value of services they provide to humans, contributing to a more comprehensive understanding of ecosystem dynamics and their role in supporting human well-being.
ESSAY ON GLOBAL WARMING: SOLAR RAYS. FRIEND OR FOE?
Authors: FRANCO Martín Federico , SUELDO Juan Pablo
Published: January 2025

In this review, the documentary “An Inconvenient Truth”, directed by Davis Guggenheim and presented by the former Vice President of the United States, Al Gore, has been analyzed, focusing on the mechanisms by which solar radiation and infrared radiation (IR) contribute to the Earth’s energy dynamics, and how these phenomena impact global warming, terrestrial albedo, the greenhouse effect and the regulation of atmospheric temperature. Discussing also the information that the documentary inspires to provide with it, the analysis was opened through a literature search and the review of five keywords in order to highlight the role of science communication and its function in promoting and providing clear examples of how the phenomenon of climate change has manifested itself in recent years.

Published: January 2025

We developed a laccase biosensor by modifying glassy carbon electrodes with single-walled carbon nanotubes functionalized with diazonium salt. The biosensor provided fast, stable, and sensitive electroanalytical responses to different polyphenols and was successfully applied to determine the total content of polyphenols in quince extracts. The results obtained indicate that the biosensor is a new analytical tool that avoids the interferences of the Folin-Ciocalteu method and represents a simple alternative compared to chromatography.

Published: January 2025

Background: The demand for scientific creativity has become essential for societal progress, enabling the generation of innovative ideas to address current and future challenges. Aims: The study evaluates the convergent scientific creative competence of secondary education students and analyze how grade level, gender, cognitive reflection, and metacognitive skills (calibration) affect it. Methods: To carry out this study, several specific tests were used. To measure cognitive reflection, a test based on the “Cognitive Reflection Test-Developmental (CRT-D)” with nine questions by Young & Shtulman (2020) was employed. Additionally, to assess convergent scientific creativity and metacognitive calibration, a test based on the work of Yang et al. (2019) was utilized. A statistical analysis was then conducted to examine the relationships between these variables. Results: Students' convergent scientific creative competence is generally low. Additionally, there is no significant influence of gender or academic level on this competence. Regression analysis shows that calibration is the only significant predictor variable. Mediation analysis reveals that calibration acts as a mediator between cognitive reflection and convergent scientific creativity.. Discussion: These findings highlight the crucial role of both cognitive reflection and accurate self-assessment in enhancing students' convergent scientific creativity. The lack of gender or academic level influence suggests that educational strategies should focus on developing metacognitive skills across all demographics. Conclusions: Students' convergent scientific creativity is generally low and is not influenced by academic level or gender. It is primarily predicted by calibration, with cognitive reflection playing a mediating role.
