Old Knowledge, New Tools: Applying an Indigenous Approach to Social Network Analysis
Authors: Hesketh Martell
Published: January 2025

Program work with American Indian and Alaska Native (AI/AN) communities necessitates Indigenous approaches and methods for evaluation. AI/AN researchers are working to reclaim evaluation as a traditional value and identify methods that fit into existing Indigenous evaluation frameworks. However, an increased understanding of how to utilize data collection tools appropriately and how they fit within these Indigenous frameworks is still needed. In this article, the author describes the process, rationale, and reflections on using a social network analysis tool while grounded in Indigenous evaluation principles. We discuss how displaying the results using a GIS story map can tell the story of a community of practice of Indigenous plants and foods educators. This article addresses the Southern Door—Be of Good Mind—as it describes a method that centres on community, honors relationships, and focuses on resiliency. By presenting the results through a GIS story map, the data can be gifted back to the communities and connect the relationships on a spatial scale to honour the inseparable connections between Indigenous plants and foods work and the land on which it takes place.

The energy thresholds and the kinetics of explosive decomposition of pentaerythritol tetranitrate (PETN) and its composites induced by the laser pulse (λ0 = 1064 nm; τи = 12 ns) in dependence on the concentration of absorbing additives and different volume compression within the range from 40 to 600 MPa are experimen- tally studied. The sensitivity of pure PETN and its composites increases along with the volume compression value. For low pressures (less than 200 MPa) with the increase of additives concentration the sensitivity of mixtures to laser pulse exposure increases and for higher pressures (more than 300 MPa) — it decreases. Such behavior is explained from the perspective of both diffuse light scattering and the thermal micro-spot model of initiating the transparent explosive components (the “hot spot” model), according to which the reac- tive capacity of hot spots is determined by their heat reserve, their concentration and the scale of gas dynamic unloading in the neighboring to hot spots pores and through the sample surface pressed by the input window (the area of low pressures), as well as by the heat conducting unloading of hot spots in the explosive compo- nents matrix and the covering glass (the area of high pressures).

In the article a method for diagnosing electron beam oscillations in ELV-type accelerators associated with the penetration of a transverse magnetic field from the primary and secondary windings into the accelerating tube was described. A method for suppressing these oscillations was developed and tested using the ELV-8 accel- erator with an extraction device capable of extract a focused electron beam into the atmosphere. After sup- pressing the oscillations, it was possible to extract a focused electron beam with a power of 100 kW into the atmosphere and increase the service life of the diaphragms.

Published: January 2025

The research conducted during of last few years showed the advantages of the method of producing of the luminescence ceramic materials as well as the other purposes ceramics with using of electron beam with high penetrating power. In this technology, an industrial accelerator generates the beam and then it enters the at- mosphere throw the hole of small diameter. The accelerating voltage of the electrons is regulated in the range of 1.4 — 2.5 MV, which, in combination with the high beam power, allows for a volumetric effect on the powder material, producing its melting in about 1 s, with virtually no contact between the melt and the walls of the crucible in which the initial batch is placed. The paper proposes a method for calculating the energy ef- ficiency of a beam during the synthesis of two-component oxide ceramics. The measurements show that the beam efficiency is on average about 50 %, and in many cases exceeds 80 %, regardless of the melting tem- perature of the synthesized ceramics and the heat required to heat and melt it.

The work is devoted to the development of the model describing laser initiation composite materials being an explosive matrix with metal nanoparticles covered with oxide shell. The model considers the oxide shell as a dielectric that does not absorb light. The example of aluminum nanoparticles covered with alumina is the main one in the paper. The model describes the thermal transfer in the system metal core-oxide shell- explosive material, exothermic decomposition of the explosive considered as a one-step reaction with Arrhe- nius dependence on the rate on temperature, and light absorption of the core-shell interface. The model is written as a system of the equations and respective computer program is developed. The semi-quantitative analysis of the model using the typical thickness of the heated layer of the matrix is performed. It is shown that the radius of the nanoparticle heated most is proportional to the thickness of the heated layer of the ex- plosive matrix as in the previous versions of the model though the coefficient depends on the oxide shell thickness. The numerical analysis is done. The dependencies of critical energy density on the oxide shell thickness at constant nanoparticle’s radius and on the radius at constant shell thickness are calculated. The dependence on radius shows the existence of the optimal particle minimizing the critical energy density whose radius depends on the shell thickness.
Cathodoluminescence properties of oxide and fluoride ceramics synthesized in the field of high-energy electrons flux
Authors: Karnaukhova А.А. , Yakovlev V.Y.
Published: January 2025

Traditionally, the synthesis of refractory ceramics is a complex and time-consuming process. Some time ago, a new, much faster method was proposed — the method of synthesis of luminescent ceramics in the field of a powerful flux of high-energy electrons. In the synthesis of multicomponent oxide phosphors, it is not an easy task to determine the dependencies of the properties of the resulting material on the composition of the raw mixture and the modes of the synthesis process. In this regard, it seems logical to study the properties of ce- ramics made by radiation synthesis from simple oxides, which are components of more complex phosphors. An investigation of the spectral and kinetic patterns of cathodoluminescence of ceramic samples of metal ox- ides (Ga2O3, Al2O3, Y2O3) and fluorides (MgF2, BaF2) obtained by radiation synthesis method was carried out. The paper presents an analysis of the cathodoluminescence spectra of the studied samples with the allo- cation of elementary bands, conclusions about the dynamics of luminescence decay are made. The obtained results are compared with the known data on single crystal samples. It is shown that, unlike oxide ceramics, the spectral characteristics of MgF2 and BaF2 ceramic samples show good agreement with the data on single crystals of these compounds.

Published: January 2025

Este artigo teve como objetivo analisar as práticas de três professoras de uma escola municipal do interior de Minas Gerais em relação ao ensino de Ciências para turmas do 5º ano do Ensino Fundamental I, investigando em que medida sua formação acadêmica deu suporte para as aulas e como eram desenvolvidas essas aulas. Para isso, realizou-se uma entrevista semiestruturada com três professoras dessa instituição de ensino. Os principais resultados foram que as professoras entrevistadas tiveram pouco embasamento em sua formação acadêmica para auxiliá-las a como realizar aulas práticas, já que a graduação da maioria delas aconteceu na modalidade à distância. Foi possível, também, analisar e inferir que a constituição de uma prática docente ao longo da carreira se estabelece como um ponto importante para ensinar os conteúdos científicos. Sendo assim, quando as docentes afirmam que a formação inicial não interfere em suas aulas, podemos dizer que o fazer cotidiano e o estudo dos materiais é o que direciona as propostas metodológicas. O que em certa medida pode nos levar a questionar sobre quais caminhos seguidos pelas docentes para alcançar uma alfabetização científica ou até mesmo apresentar conceitos que possam contribuir para a superação do negacionismo científico.

Incentivar a ciência é promover descobertas e estimular formação de futuros cientistas. No âmbito escolar, as Feiras de Ciências impulsionam a pesquisa científica estimulando a curiosidade e a investigação científica, proporcionando um ambiente enriquecedor e que transforma a interação entre o professor e o aluno, construindo uma imagem do professor como de orientador ao longo do processo. Portanto, o objetivo deste trabalho foi analisar os projetos da feira de ciência dos segundos anos do Ensino Médio, identificando pontos positivos e negativos para propor melhorias e auxiliar os educadores de ciências a tornar a feira de ciências um processo de aprendizagem mais eficaz. Os resultados foram obtidos por meio de aplicação de um questionário online onde os alunos e professores/orientadores responderam de forma voluntária e anônima sendo os mesmos quantificados em porcentagem. Os professores tiveram a possibilidade de se expressar individualmente através de uma pergunta com resposta dissertativa o que teve grande valia na interpretação dos resultados. Os resultados mostram que a maioria dos alunos se sentiu motivada pelo tema central da feira, mas a falta de tempo voltado para feira também foi destaque nos resultados. Com relação à avaliação dos professores, eles apresentam a falta de tempo como determinante para o sucesso da feira e acrescentam que é de extrema importância a inclusão de um letramento metodológico e científico.

The June 1985 Withdrawal That Never Was
Authors: Kaufman Asher
Published: January 2025

This article revisits the 1983 Israel-Lebanon Agreement using new archival material, mainly from the Israel State Archives, with three main goals. First, it demonstrates the centrality of the agreement for Israeli schemes in Lebanon and argues that Israeli demands during the negotiations shed new light on its decision to stay in Lebanon in June 1985, despite the government decision of January 1985 to withdraw to the international border. Second, it reconsiders Syria's ‘veto power’ over the agreement given Israel's objectives to establish a security zone in south Lebanon. Finally, by using new archival evidence, it completes our historical knowledge about the road to the agreement and its aftermath.
The Conditions for Creating the Varying Image of Middle Eastern and North African Jews in Israel in the 1950s
Authors: Guedj David
Published: January 2025

This article examines the personal diary of Dr. Michael Simon, the first chief of protocol for Israel's Ministry of Foreign Affairs, that he wrote in April 1955 during his visit to Morocco. The diary raises questions about the beliefs, perceptions, stances, and images that prevailed among European Jews in Israel vis-à-vis Middle Eastern and North African Jews during the first decade of the State of Israel's existence. I propose that Simon's outlook on Moroccan Jewry was complex, integrative, and free of stereotypes. Analyzing Simon's case enables an exploration of the conditions that informed his views of Morocco's Jews, conditions that were manifested in different ways by most of the Israelis of European heritage whose writings dealt with Middle East and North Africa Jews and their descendants in Israel.

Published: January 2025

This paper gives a look on producing energy using wind turbines and imposing robust Maximum Power Point Tracking (MPPT) technique to operate around an optimal rotational speed. A mechanical speed control based on PI controller is presented in order to extract the maximum power and optimizing the conversion efficiency of wind's kinetic energy into electric energy. A doubly-fed induction generator (DFIG) is utilized because it is preferable for applications in wind energy systems referring to the capability to regulate the output voltage and improve the stability of the grid. Its operational characteristics and the regulating procedures such as Indirect Vector Control (IVC) and other sophisticated strategies for instance the ANFIS controller enhance operating flexibility and optimum performance under diverse conditions. This has attributed the split to the improved ANFIS in that it includes the artificial neural networks besides the fuzzy logic since they improve on learning as well as parameter fine tuning. Some of them are working with a comparatively fewer number of data sets; and therefore, it can be useful in classification, modeling and control. This configuration enables to regulate the generator's magnetic flux, torque, and reactive power, adjusting to changes inside wind velocity and disruptions within the grid. The performance of the proposed MPPT-IIVC method is examined by way of simulations in Matlab/Simulink. The simulations concerned a dynamic model incorporating the wind turbine, the DFIG, and the electric grid. The results show that the proposed technique can incredibly enhance the wind energy, maintain precise regulation over speed, and effectively adjust and regulate grid voltage and frequency. The performance of the proposed ANFIS controller is compared with a PI controller and discovered that ANFIS enhances the robustness, precision, dynamic response, total harmonic distortion THD (%) of the injected current into the grid, the reference tracking ability and Overshoot (%).

This study aims to develop a control system for a robot arm, designed to perform precise movements along a predefined path, suitable for various industrial applications. The robot arm's movements are driven by three electric motors, each responsible for controlling a joint, enabling the arm to follow the required path accurately. To manage the complexity of multiple motors and dynamic movement requirements, an automated control system has been developed, tailored to meet the specific demands of the proposed task. A highly efficient, reliable, and safe control system design is being developed and simulated to evaluate its effectiveness in executing the required path. A simulation model is being constructed to assess the system's ability to follow the prescribed path, its responsiveness to disturbances and transient conditions, and the overall accuracy of the arm's movements. Simulation results will be analyzed to determine the system's performance across various scenarios, evaluating its adaptability to the work environment and its ability to achieve tasks with high accuracy, thereby enhancing system effectiveness.
Systematic Review of Unmanned Aerial Vehicles Control: Challenges, Solutions, and Meta-Heuristic Optimization
Authors: Basil Noorulden , Sabbar Bayan Mahdi , Marhoon Hamzah M. , Mohammed Abdullah Fadhil , Ma'arif Alfian
Published: January 2025

Unmanned Aerial Vehicles (UAVs) are powerful tools with vast potential, yet they face significant challenges. One of the primary issues is flight endurance, limited by current battery technology. Researchers are exploring alternative power sources, including hybrid systems and internal combustion engines, and considering docking stations for battery exchange or recharging. Beyond endurance, UAVs must address safety, efficient path planning, payload capacity balancing, and flight autonomy. The complexity increases when considering swarming behaviour, collision avoidance, and communication protocols. Despite these challenges, research continues to unlock UAVs’ potential, with path planning optimization significantly advanced by meta-heuristic algorithms like the Cuckoo Optimization Algorithm (COA). Whereas, meta-heuristic algorithms can be defined as system-level strategies that are used to seek suboptimal solutions to optimization problems. It uses heuristic approaches together with the exploration/exploitation scheme in order to effectively employ within large solution spaces. However, dynamic environments still present difficulties. UAVs have evolved beyond recreational use, becoming essential in industries like agriculture, delivery services, surveillance, and disaster relief. By resolving issues related to autonomy, battery longevity, and security, the benefits of UAV technology can be fully optimized. This systematic review emphasizes the importance of continuous innovation in UAV research to overcome these challenges.
Pleistocene loess-soil sequence and aeolian relief of Western Siberia: chronology and features of their formation
Authors: Zykina V. S. , Zykin V. S. , Malikova E. L.
Published: January 2025

The article discusses the current state of chronostratigraphy and paleogeography of the loess-soil sequence of the Pleistocene of Western Siberia, which is one of the most complete in Northern Eurasia. It is shown that genetically loess is closely related to eolian formations formed as a result of activation of eolian processes in earlier arid epochs of the Late Cenozoic in North Asia. A deflationary and accumulative eolian relief, paragenetically associated with the formation of the subaerial formation, is described, showing a slight transfer of material that forms the loess stratum. It has been established that the eolian relief and the activation of eolian processes occurred during the cold periods of the Pleistocene with the predominance of southwestern winds. The basis of the stratigraphic subdivision and correlation of sections of the loess strata are fossil soils formed under strictly defined climatic conditions. Consistent tracking of the loess and soil horizons of the loess sequence of the Pleistocene of Western Siberia, taking into account radiocarbon and luminescent dating and the use of climatostratigraphic correlations, showed that its structure and composition clearly reflect the uniqueness of each paleogeographic epoch, associated with changes in the intensity of atmospheric circulation in the cold and warm epochs of the Pleistocene. The features of each specific epoch are recorded in a combination of unique individual features of certain horizons of the loess-soil sequence. In the alternating horizons of loesses and soils, a record of global and regional changes in landscapes and climate has been preserved, reflecting the originality and uniqueness of the paleogeography of each time epoch. The structure and composition of the loess strata reflect the different intensity of atmospheric circulation during the cold and warm epochs of the Pleistocene. It is shown that the chronological sequence of the loess-soil sequence of Western Siberia, based only on OSL dates, does not always coincide with the loess-soil sequence of Western Siberia, built on the integration of various approaches, with the predominant use of the paleopedological method, and therefore needs to be corrected. The best correlation results are achieved by combining all available dating methods with the involvement of biostratigraphic, sedimentological and geological data, based on the climatostratigraphic principle.

Authors: Markova A. K.
Published: January 2025

The investigation of the Pleistocene small mammal faunas from the south-western regions of the Russian Plain permits to reconstruct their principal evolutional stages during last ~1 400 000 yr. These materials took the possibilities to date the Pleistocene alluvial, liman and marine deposits and also the horizons of the fossil soils.
The unique small mammal and brackish-water mollusk localities in marine and liman-deltaic deposits of the Black Sea permits to demonstrate a direct correlation between the events in the Black Sea basin and on the continent. The direct correlations of the events (transgressions) in the Black Sea and on the continent were made based on the joint finds of the brackish-water mollusks and the small mammal remains. Thus, the Tiraspolian faunas synchronous to the Chaudian transgression of the Black Sea; the faunas of the Gunkovian small mammal assemblage (MIS 11, Likhvin interglacial) are correlated to the Early Euxinian transgression. The faunas existing in the last warming (Interglacial?) of the Middle Pleistocene (MIS 7) are synchronous to the Uzunlar transgression, and the faunas of the Mikulino (=Eemian) Interglacial are correlated with Karangat transgression (MIS 5e). The species of the open (steppe and forest-steppe) landscapes prevailed in the all of the faunas.

The article is dedicated to the development of a comprehensive approach to assessing the economic, environmental, and organizational-legal security of agribusiness entities. The aim of the study is to analyze, systematize, and generalize the existing theoretical and methodological foundations of security for business entities and to develop a comprehensive approach to evaluating the economic, environmental, and organizational-legal security of agricultural enterprises.The article examines the importance of assessing the level of security in agribusiness as a key element of ensuring the efficiency, stability, and adaptability of enterprises operating in a complex and dynamic environment. A systemic approach to security evaluation is presented, which includes the analysis of economic, environmental, social, and technological aspects. It is revealed that agribusinesses face numerous challenges, such as economic uncertainty, climate change, market fluctuations, and technological innovations, requiring a comprehensive approach to identifying risks and developing appropriate response strategies.The need for integrating various security components into a unified system to ensure the resilience of agribusiness is substantiated. Key aspects of assessment are outlined, including economic security, environmental sustainability, and organizational-legal security. Economic security assessment involves analyzing financial indicators, capital stability, and resource use efficiency, enabling agricultural enterprises to optimize their operations and adapt to changing conditions. Environmental security is a crucial component for agribusiness, as enterprises are dependent on natural resources and face risks related to climate change. Evaluating environmental aspects, such as soil degradation, water scarcity, and CO2 emissions, helps develop sustainable farming practices, including the use of precision farming technologies. Organizational-legal security is also an important factor, as changes in legislation, new certification and licensing requirements, and other legal initiatives can significantly impact business operations.The research identified key vulnerabilities in agribusiness, particularly in financial, environmental, and organizational-legal aspects. A comprehensive approach to assessing the security level of agribusinesses is proposed, which includes multifactorial analysis, scenario modeling, and the use of digital technologies to improve forecast accuracy and management decision-making. Assessing compliance with economic, environmental, and organizational-legal security contributes to the strategic development of enterprises, allowing them to enhance their resilience to external challenges.

DECONTAMINATION OF SLUDGE THROUGH THE USE OF A STABILIZER ADAPT MADE BY "DEVNYA CEMENT" AD
Authors: Marinova Svetla , Zlatareva Elena , Catidotes Nicholas
Published: January 2025

The large amount of sludge that is generated in wastewater treatment plants /WWTP/ and the lack of drying fields to stabilize them necessitates the conduct of this study. The use of sludge in practice can be a source of biological contamination of soil, water and plants, including pathogenic microorganisms. Regardless of the developed normative documents, there are a number of problems in practice that limit the realization of sewage sludge. One of these problems is related to the disturbed microbiological parameters in most treatment plants. Sludge storage is used as the only way to eliminate pathogenic microorganisms. This method is not effective enough since it requires large areas for sludge storage. The purpose of the study was to determine the possibility of decontamination of sewage sludge using an ADAPT stabilizer for waste treatment produced by ‚Devnya Cement‘ AD. For the preparation of the cement clinker, mainly natural rock materials are used, which, after crushing and grinding, form a "raw material mixture" consisting of natural survins and industrial products containing the major minor oxides - CaO, Si02 , Al2 O3 and Fe2 O3. Fresh sludge from WWTP Varna was used, treated with 20, 25 and 35% of the stabilizer. The sludge was analyzed before and after treatment by agrochemicals and microbiological parameters. It was found that the most effective treatment was with 20% sludge dry stabilizer treatment for a period of 20 days. Treatment of the sludge with the stabilizer does not have a negative effect on their chemical and agrochemical characteristics.
Enhancing Sample Generation of Diffusion Models using Noise Level Correction
Authors: Abuduweili Abulikemu , Yuan Chenyang , Liu Changliu , Permenter Frank
Published: January 2025

The denoising process of diffusion models can be interpreted as a projection of noisy samples onto the data manifold. Moreover, the noise level in these samples approximates their distance to the underlying manifold. Building on this insight, we propose a novel method to enhance sample generation by aligning the estimated noise level with the true distance of noisy samples to the manifold. Specifically, we introduce a noise level correction network, leveraging a pre-trained denoising network, to refine noise level estimates during the denoising process. Additionally, we extend this approach to various image restoration tasks by integrating task-specific constraints, including inpainting, deblurring, super-resolution, colorization, and compressed sensing. Experimental results demonstrate that our method significantly improves sample quality in both unconstrained and constrained generation scenarios. Notably, the proposed noise level correction framework is compatible with existing denoising schedulers (e.g., DDIM), offering additional performance improvements.

Cargo delivery is one of the most popular areas of application of aircraft-type UAVs with the Ardupilot control system. Autonomous missions performed by such UAVs are associated with the need to determine the point of discharge of unguided cargo, which significantly affects the accuracy of its delivery. However, Ardupilot is not equipped with a software module for determining the point of discharge of unguided cargo, and such additional software is recommended to be developed in Lua. Known software modules for determining the point of discharge of UAVs, as a rule, perform a cyclic solution of a complex system of differential equations of cargo motion, which requires significant hardware resources. However, for heights up to 400 m relative to the ground surface, it is possible to use simplified analytical expressions of cargo motion with a delivery accuracy of ±5 m to increase the efficiency of the specified software module. Therefore, the object of research is the process of determining the point of discharge of unguided cargo from an aircraft-type UAV using a Lua script. The subject of research is a computer model of the movement of unguided cargo in Lua, on the basis of which the point of discharge is determined. The aim of the work is to develop a software module in Lua to determine the point of dropping an unguided cargo from an aircraft-type UAV with the ArduPilot control system by using simplified equations of motion of the cargo at altitudes up to 400 m. The following results were obtained: a general algorithm for the operation of the software module for determining the point of dropping an unguided cargo was developed, a Lua script was developed to determine the point of dropping from heights up to 40 m, a Lua script was developed to determine the point of dropping from heights from 40 to 400 m relative to the ground surface, a Lua script was provided to determine the point of dropping from heights above 400 m relative to the ground surface, and the user interface of the software module was implemented. Conclusion: a software module was developed in Lua to determine the point of dropping an unguided cargo from an aircraft-type UAV with the Ardupilot control system. A feature of this software is the use of different approaches to determining the point of dropping in the intervals of heights up to 40 m, from 40 to 400 m and more than 400 m relative to the ground surface. This makes this software module more effective at low altitudes.

An investigation of the impact of leadership practices on student learning and development outcomes in Singapore schools
Authors: Goh Jonathan , Salleh Hairon
Published: January 2025

Policymakers and the public in many developed countries have demanded for greater public school accountability in the hope of improving academic and non-academic school outcomes, as well as decreasing the achievement gaps among subpopulations of students (Heck & Moriyama, 2010). In response, there has been a growing conversation amongst educational practitioners and researchers on how educational leadership might be linked to effective teaching, and student learning and ‘achievement’ outcomes. Educational-effectiveness researchers have attempted to link (directly and/or indirect) existing research with theory about educational processes to identify contextual, school factors (including leadership), and classroom factors (including teacher effectiveness) to student learning and ‘achievement’ outcomes (Creemers, 1994; Creemers & Kyriakides, 2008; Heck & Moriyama, 2010; Leithwood & Mascall, 2008; Scheerens, 1990, 1992; Stringfield & Slavin, 1992; Teddlie & Reynolds, 2000).

It is clear that the ‘Principal as the sole decision maker’ conception of leadership and bureaucratic organizational structures are no longer consistent with the new school leadership climate (Pearce & Conger, 2003). Proponents of this view have argued that a dispersed form of leadership is thought to enhance opportunities for the organization to benefit from the capacities of more of its members rather than a single leader (Leithwood & Mascall, 2008).
Programa “tarifa 10” e a acessibilidade dos serviços de água e esgoto em Manaus
Authors: Carvalho Débora da Costa
Published: January 2025

A universalização do acesso ao saneamento básico no Brasil enfrenta, além das dificuldades relacionadas a infraestrutura e investimentos, a baixa possibilidade de acesso por aqueles que estão em classes sociais vulneráveis, especialmente se comparando os aumentos dos preços dos serviços e a redução da renda real das famílias com a inflação no país nos últimos anos. Este trabalho buscou analisar as premissas e primeiros resultados do Programa Tarifa 10, por meio do qual famílias em situação de extrema vulnerabilidade social podem ter acesso aos serviços de água e esgoto mediante o pagamento de uma tarifa única de R$ 10,00. Para isso, realizou-se pesquisa bibliográfica e documental, com as informações qualitativas e quantitativas disponíveis. Verificou-se que o programa parte de pressupostos sólidos, com atores e papéis definidos, com grande capacidade de facilitar o acesso aos serviços a um preço que não comprometa o orçamento de famílias socialmente vulneráveis. No primeiro ano de execução, foi alcançada a meta de 28 mil famílias beneficiadas com o desconto. No entanto, há necessidade de alcance de mais pessoas que vivem em situação de extrema pobreza no município, o que requer esforços que vão além da concessionária prestadora dos serviços.
