Evaluation of turbidity removal at the Seminário WTP
type: item
description: Objective - To perform a statistical analysis of the efficiency of the aluminum polychloride (PAC) coagulant used at the Seminário Water Treatment Plant (WTP), located in the municipality of Mariana, Minas Gerais, in comparison with aluminum sulfate (Al₂(SO₄)₃), which was used at the plant until 2020, with a specific focus on turbidity removal. Additionally, the study aims to assess the compliance of recorded treated water turbidity values with the current drinking water standards for this parameter, comparing the performance of the coagulants in meeting regulatory criteria. Methodology - Treated water turbidity data for both coagulants were obtained from the personnel responsible for the operation of the Seminário WTP. As the records were collected manually, they were digitized for subsequent statistical processing. Statistical analysis was conducted using the Kolmogorov-Smirnov (KS) test to verify data adherence to a normal distribution. Subsequently, the nonparametric Mann-Whitney U test was applied to identify possible statistically significant differences between the medians of the samples associated with the use of PAC and Al₂(SO₄)₃. Originality/Relevance - There is a scarcity of studies that comparatively evaluate, through statistical methods, the efficiency of these two coagulants based on extensive operational datasets, particularly regarding turbidity reduction. The academic relevance of this study lies in the application of statistical methods to real operational data, expanding knowledge about coagulant performance in practical contexts and providing support for future research in the fields of water treatment and sanitation. Results - The KS test indicated that the samples do not follow a normal distribution. The Mann-Whitney U test showed that the median turbidity after treatment with PAC is statistically lower than the median turbidity after treatment with Al₂(SO₄)₃, demonstrating the greater efficiency of PAC in turbidity removal. With respect to dri…

Attributing Urban Ensembles as a Possibility for Preserving Cultural Heritage in Londrina, Paraná, Brazil
type: item
description: Objective – This study aimed to identify how the preservation of historical heritage has been carried out in Londrina. Seeking to reflect on events and/or changes that may have affected the environmental character of historical contexts, the paper presents a preservation pathway grounded in the concept of urban ensembles, to support the delimitation of cultural protection areas and the application of guidelines. Methodology – Based on a thematic focus on the management of historical-cultural heritage in Londrina and a spatial cutout centered on the Vila Casoni subdivision, the research adopted a qualitative approach and employed descriptive and exploratory methods. Operational procedures included data collection from primary sources (simple observation and photographic records) and secondary sources (bibliographic production and inventory forms). Originality/Relevance – The originality of the study lies in proposing the interpretation and management of Londrina’s historical-cultural heritage through the lens of urban ensembles, moving beyond an approach exclusively centered on individual buildings or isolated assets. By incorporating the notion of “environmental character,” the research emphasizes that preservation involves not only buildings, but also spatial relations, uses, continuities, and transformations within the urban fabric. In this sense, it contributes to strengthening the local debate on the urban historic site and to improving municipal criteria for delimitation and cultural protection. Results – The findings indicate that the preservation of Londrina’s historical-cultural heritage comprises six listed buildings and multiple inventory forms that make up the documentary inventory of cultural assets of interest. These forms represent a potential pathway toward formal listing, helping to prevent alteration and/or demolition without prior public-sector assessment, and enabling the definition of new uses for these properties. This, in turn, helps dissociate…

Use of Ammonium Sulfate in Soil Produced with Residual Ammonia Liquor from the Steel Industry and Residual Sulfuric Acid from Automotive Batteries in the Initial Development of Maize (Zea Mays L.)
type: item
description: Objective –This study aims to evaluate the technical feasibility of producing ammonium sulfate from industrial residues and to assess its agronomic performance as a nitrogen and sulphur fertiliser for maize cultivation. Methodology – The research adopted an experimental approach based on controlled pot trials. Ammonium sulfate was produced using residual sulphuric acid from automotive batteries and ammonia liquor from the steel industry. A second formulation was prepared using residual acid and commercial ammonia, while analytical-grade ammonium sulfate (P.A.) was used as a reference. Fertiliser solutions were applied to soil at nitrogen rates ranging from 20 to 120 kg N·ha⁻¹, followed by sowing of maize (Zea mays L.). Plant growth and biomass accumulation were subsequently evaluated. Originality/Relevance – The study addresses a relevant gap concerning the reuse of industrial residues for fertiliser production, contributing to discussions on reducing Brazil’s dependence on imported fertilisers. It advances knowledge on alternative nutrient sources aligned with circular economy principles. Results – Maize plants showed positive responses to all ammonium sulfate sources tested. However, higher application rates resulted in phytotoxic effects, particularly in aerial biomass, while root biomass was negatively affected even at lower nitrogen doses. Theoretical/Methodological Contributions – The findings contribute to the understanding of nutrient dynamics and toxicity thresholds associated with alternative ammonium sulfate sources, offering methodological insights for evaluating residue-derived fertilisers under controlled conditions. Social and Environmental Contributions – The proposed approach promotes the valorisation of industrial residues, potentially reducing environmental liabilities and contributing to more sustainable fertiliser supply chains. Additionally, it supports strategies aimed at enhancing agricultural sustainability and fostering a more resilient and…

Population aging in small towns and the promotion of health and well-being
type: item
description: Objective – To investigate public policies aimed at promoting health and well-being among older adults, specifically physical exercise, in the small town of Centenário do Sul, Paraná, Brazil. Methodology – To this end, an exploratory qualitative study was conducted, using simple observation and structured interviews with older adults residing in Centenário do Sul, Paraná, Brazil. Originality/Relevance – The study stands out for focusing on the interface between population aging, public policies, and the everyday use of preventive health urban facilities in a small town—an empirical setting that remains underexplored compared with analyses concentrated in metropolitan centers. It is also relevant to policy formulation, as it shows that the mere provision of infrastructure does not, in itself, ensure adherence or changes in habits. Results – The findings indicate that the outdoor gyms have not been used by older adults living in the neighborhoods where they were installed; that older adults do not conceive physical exercise as a means of promoting health; and that there are no municipal management actions that contribute to building a new perspective on physical exercise in old age. Theoretical/Methodological Contributions – The research contributes by linking the discussion of aging to the production/use of urban space and to the effectiveness of public policies in non-metropolitan contexts, highlighting socio-territorial dimensions (location, accessibility, meanings attributed to the equipment, routines, and sociability networks) that condition policy outcomes. Methodologically, it demonstrates the value of combining simple observation and structured interviews to capture the mismatch between institutional provision (equipment) and social appropriation (use, meaning, and practices). Social and Environmental Contributions – The findings provide support for improving municipal policies on health and well-being in later life, indicating the need for integrated actions …

Socio-spatial Segregation and Climate Vulnerability in Urban Peripheries
type: item
description: Objective – To critically analyze the relationship between socio-spatial segregation, urban policies, and climate vulnerability in Brazilian cities, demonstrating that unequal exposure to climate risks constitutes a direct expression of the capitalist production of urban space and of political choices that have historically marginalized specific territories and populations. Methodology – The study adopts a qualitative, theoretical-critical approach, characterized as an analytical essay grounded in the review and interpretation of specialized literature on the production of urban space, socio-spatial segregation, urban public policies, and climate justice. The analysis articulates different scales—from the global urban context to the Brazilian reality—and draws on empirical studies and institutional documents as interpretative support. Originality/Relevance – The originality of the study lies in articulating the critique of the unequal production of urban space with the contemporary debate on climate change, addressing a theoretical gap still insufficiently explored in urban studies: the understanding of climate vulnerability as a socially produced, territorially distributed, and politically conditioned phenomenon, rather than a natural or exclusively environmental outcome. Results – The results demonstrate that the impacts of climate change follow the geography of urban inequality, affecting more intensely peripheral areas characterized by housing precariousness, infrastructure deficits, and the historical neglect of public policies. At the same time, they show that current urban policies tend to reinforce this pattern by concentrating investments and climate adaptation strategies in central and economically valued areas. Theoretical/Methodological Contributions – The article contributes theoretically by reinforcing the centrality of climate justice as an analytical category for understanding contemporary urban inequalities, challenging technocratic and depoliticize…

Structural processes and alternative means of conflict resolution as solutions to traditional environmental processes
type: item
description: Objective - To present and discuss viable alternatives that can overcome the obstacles inherent in traditional legal proceedings, specifically in environmental disputes. Methodology - Bibliographic research, which consisted of consulting literature and legal doctrinal texts. Originality/relevance - In the environmental field, traditional forms of civil proceedings would not be adequate: the characteristics of environmental damage require a different approach. Results - It was concluded that structural processes are more appropriate for resolving complex environmental disputes, in addition to allowing for flexibility in the procedures adopted to address the problem. Alternative means of dispute resolution in the environmental field, provided for in Article 8 of the Escazú Agreement, consist of mechanisms such as mediation, conciliation, and arbitration to resolve disputes. Theoretical/methodological contributions - The complexity of environmental disputes demands overcoming the obstacles associated with traditional procedural norms. Furthermore, the use of these alternatives to traditional judicial processes will only be effective if they are conditioned on broad participation, particularly from society and from groups directly affected by the environmental problem/object in question. Social and environmental contributions - Structural environmental processes have the potential to bring about reforms/changes to the status quo, but this potential is explored little by the judiciary. Also, the use of alternative dispute resolution methods—conciliation, mediation, and arbitration—could be a viable means of overcoming obstacles such as the length of traditional processes and the economic and social disparities between the parties involved.

Evaluation of the pulmonary epithelium in rats treated with malathion
type: item
description: Objective – To analyze alterations in the pulmonary epithelium of rats subjected to oral administration of the insecticide Malathion through histopathological analysis. Methodology – Thirty female Wistar rats, initially aged 21 days, from the Central Animal Facility of the State University of Londrina – UEL, Protocol CEUA-7109, were used. The animals were randomly distributed into three experimental groups (n = 10). Two groups were treated with Malathion at doses of 10 mg/kg or 50 mg/kg of body weight. These doses correspond to 0.5% and 2.5%, respectively, of the oral LD50 for rats (oral LD50 = 2000 mg/kg). The other group (control group) received only the vehicle (soybean oil) in an equal volume. Results are presented as mean (standard deviation), p<0.05, two-factor ANOVA test. Originality/Relevance – The originality of this article lies in the scarcity of histopathological studies on the effects of Malathion on pulmonary epithelium, especially with a morphometric focus in animal models, contributing to the understanding of respiratory toxic impacts of organophosphate insecticides. Results – The results were obtained through histopathological analysis. Although there was an increase in goblet cells in the M50 group, the values were not significant due to similar means. Regarding bronchiole area, a significant increase was observed when comparing the control group with M10. For the lumen area, no major differences were observed among group means, although the M50 group showed a reduction. An increase in muscle layer thickness and inflammation score was noted in the M50 group. Theoretical/Methodological Contributions – The study contributes to improving the understanding of pulmonary toxicity mechanisms induced by organophosphates, and supports the use of histopathological and morphometric analysis as effective approaches to assess structural changes in respiratory tissues exposed to agrochemicals. Social and Environmental Contributions – The findings highlight respi…

type: item
description: Objective – This study aimed to determine the protein, energy, and phosphorus digestibility of animal ingredients (meat and bone, fish, blood, feather, and viscera meals) in diets for tambaqui (Colossoma macropomum) and Nile tilapia (Oreochromis niloticus). Methodology – A total of 48 tambaqui and 48 Nile tilapia were used, with a mean weight of 198.15 ± 3.11 g and 134.89 ± 2.22 g, respectively. The experiment followed a completely randomized design with a factorial arrangement (ingredient × species), comprising 10 treatments (five ingredients × two species), 3 temporal replications, and 8 fish per experimental unit. Originality/Relevance – This study simultaneously compared the digestibility of five animal meal ingredients for two key species of Brazilian aquaculture, namely tambaqui and tilapia, under a combined experimental protocol. This approach yielded standardized and directly comparable data, which are scarce in the literature. The practical relevance is high, as the digestibility coefficients obtained can be directly applied in feed formulation, contributing to cost reduction, improved feed efficiency, and simplified diet formulation for multispecies systems. Results – Tambaqui showed a higher apparent digestibility coefficient (ADC) for crude protein in fish meal (87.20%), whereas tilapia achieved higher ADCs for crude protein in meat and bone meal (85.43%), fish meal (86.38%), and viscera meal (85.92%). Regarding the ADC of gross energy, tilapia performed best with meat and bone meal (89.69%), whereas tambaqui exhibited higher ADC values for meat and bone (82.77%), fish (85.01%), and viscera (86.04%) meals. Both species showed the highest ADC of total phosphorus in blood meal. Furthermore, the species exhibited similar phosphorus ADC values for fish meal (68.42%), blood meal (90.36%), feather meal (55.68%), and viscera meal (60.01%). In practical terms and considering a few exceptions, the same digestibility coefficients of animal meal ingredients can be …

Influence of Boron Application on the Early Growth and Nutritional Management of Peanut (Arachis Hypogaea L.)
type: item
description: Objective - This study aimed to evaluate the effects of different doses of boric acid applied to peanut seeds (Arachis Hypogaea L.), with emphasis on their impact on seed germination, root growth, and shoot development of seedlings. Methodology - The research was conducted using a quantitative and applied approach, through an experiment carried out at the Botany Laboratory of UNESP – Campus Tupã/SP. A randomized block design was adopted, with six treatments and four replications. The data were subjected to analysis of variance (ANOVA) and Tukey’s multiple comparison test, with a 5% significance level. Originality/Relevance - This study addresses a relevant gap in agronomic literature by experimentally investigating the threshold between boron deficiency and toxicity in peanut crops—an area still underexplored for this species. Its originality lies in the integrated assessment of seed germination and vegetative development in response to increasing doses of boron. Results - The results showed that doses exceeding 60 mg of boron per kilogram of seed negatively affected germination. However, these same doses promoted increased root and shoot growth in the seedlings that emerged. The 60 mg/kg dose stood out as the most effective, offering a balance between viable germination and seedling vigor. Theoretical/Methodological Contributions - The study reinforces the importance of precision nutritional management in seed treatment, contributing theoretically to the understanding of the physiological responses of peanut plants to boron and methodologically to the refinement of experimental practices in seed analysis. Social and Environmental Contributions - The findings provide technical support for more efficient use of micronutrients, promoting sustainable and evidence-based agricultural practices, especially in peanut-producing regions such as Tupã/SP. The implementation of such practices can reduce input waste, enhance productivity, and support responsible agriculture.

Methodology – The research was conducted through field tests. Sludge was collected from the decanters of a WTP, and this was followed by an evaluation of the chemical conditioning of this waste with cone tests. The sludge was subsequently dewatered in GTX bags under two experimental conditions, namely, with LCs and without LCs, both of which were performed in replicates. The tests included three successive filling cycles, with monitoring of the turbidity (NTU), filtrate mass (kg), mass retained in the bags (kg), filling height and total solid (TS) content in the sludge and filtrate (mg/L). Additionally, efficiency parameters, including the filtration efficiency (FE), the dewatering efficiency (DE), passing solid (SP) rate and piping (PP), were determined. Originality/relevance – The study addresses contemporary challenges related to the treatment and proper disposal of waste generated by WTPs. In the context of the dewatering of sludge under conditions with LCs and without LCs, the technical feasibility of the use of GTX systems in confined environments, GTX systems that are subjected to lateral forces, and the use of GTX systems in emergency situations is discussed. The aim is to broaden the application perspectives of this technology, as evidenced in the specialized literature. Results – Chemical conditioning is relevant to making the dewatering of solid wastes with high liquid contents and high levels of resistances to filtration viable. In this context, the anionic polymer A110 was used at a concentration of 0.2% and dosage of 30 mL/L. The tests performed with LCs showed better efficiency, with a FE of 99.5%, a SP rate of 0.5% and a particles loss (PP) of 0. 8 g/m². Additionally, lower turbidity values were recorded in the filtrates obtained under dewatering c…

Water resource management, the environment, and challenges in the municipal territory
type: item
description: Objective - The objective of this research was to analyze water resource management, its challenges, and its relationship with the environment in the municipality of Presidente Epitácio, state of São Paulo, with the aim of contributing to environmental planning. Methodology - The methodology adopted consisted of a bibliographic survey and literature review, mapping, secondary data collection, fieldwork, and photographic records. Originality/relevance - Concern about water availability has grown, even in areas previously considered safe. This highlights the importance of studies on water resource management and environmental planning of river basins, which are fundamental for their conservation and essential for ecological processes and biodiversity preservation. Studies of this nature are incipient in the municipal territory, although the municipality is legally equipped with administrative autonomy. Results - The results revealed that the municipality's watercourses are significantly silted up and lack Permanent Preservation Areas (APP) in accordance with current legislation, in addition to not having adequate vegetation. This situation compromises rainwater infiltration and aquifer recharge, causing flooding in the urban area. In addition, it was observed that the use of water resources is predominantly driven by economic activities, and there is a lack of clarity and empowerment in municipal action regarding water management. Theoretical/methodological contributions - The study highlights the need to discuss and adopt environmental management strategies, focusing on water resources at the municipal level. Social and environmental contributions – The research results emphasize that the municipality plays an essential role in water resource management and can no longer delegate this responsibility solely to the state and federal governments.
