Harttia genus comprises a fish group widely distributed in hydrographic basins of South America. In the cytogenetic point of view, present large karyotypic variation, including an extensive variation in position of ribosomal DNA, B chromosome presence and diversified sex chromosome systems. It is proposed the occurrence of chromosomal instability sites present on the genome of this species could lead the DNA double strand breaks, which trigger these chromosomal rearrangements. Thus, this work aimed to analyze rearrangements and the chromosome involved on karyotypic differentiation in Harttia species, as well the accumulation of repetitive sequence in these regions. Ten species were collected in different hydrographic basins of south, southeast and middlewest regions, including two new not described species. Firstly, classical, and molecular cytogenetic tools were used, including in situ hybridization of ribosomal genes and telomeric sequences, in addition to comparative genomic hybridization essays. The results reveal two new cases occurrence of multiple sex chromosome XX/XY1Y2, besides of new not described species with the highest diploid number founded in the genus. In the investigation of chromosomal rearrangements, was used the microdissection and whole chromosome painting techniques. Were isolated six different chromosomes: 25 (X1) and 26 (X2) from H. punctata, 9 and X (pair 1) chromosome from H. carvalhoi, X chromosome (pair 1) from H. intermontana and chromosome 1 from H. torrenticola. The chromosome painting results using the X1 and X2 probes indicated several chromosomal rearrangements occurred during the diversification of Harttia species from south and southeast regions. With these results, was possible detect that chromosomal breakpoint regions are located inside or surrounding the ribosomal DNA sites in Harttia genome, and these sites triggered several events of chromosomal remodeling. The chromosome painting results obtained with X chromosome probes and chromosome 9 of H. carvalhoi showed that fusion centric events were responsible for the origin of these chromosomes and for decrease in diploid number variation in this lineage. The chromosome 1 of H. torrenticola demonstrated high homeology to chromosome X of H. carvalhoi. Although with similar morphology, the X chromosome of H. intermontana arise from a translocation event between X and autosome (chromosome 9 of H. carvalhoi) besides the identification of other chromosomal rearrangements that triggered the repositioning of homeology blocks on the karyotype of this species. Furthermore, demonstrated two different types of multiple sex chromosome systems founded in the genus, had independent evolutive origin. About the investigation of repetitive sequences associated with this instability regions, were mapped microsatellite sequences and analyzed regarding to the accumulation in chromosomal rearrangements occurred regions. It was observed an enrichment of different sequences in double strand break region. Although a genomic characterization can be necessary to identify the instable sites, the results obtained point to double strand breakpoints in Harttia genome and reaffirm the high karyotypic plasticity in the genus.

Memory, knowledge, and practices related to the human ecology of riverine populations in the Amanã Lake (AM) are treated in this study from a women's perspective. The work also presents and discusses aspects of women’s ecological knowledge, as well the woman's role in the productive activities in the household economy scale. Historical fragments about the region are also presented, bringing to light aspects of the past way of life of its population. It was carried out 22-days fieldwork among riverine communities in the Amanã Lake. The study makes use of an ethnographic approach, with the application of informal and semi-structured interviews, as well participant observation in the field. Boa Esperança, Boa Vista do Calafate, Santa Luzia, and Ubim were visited during the research. Six women, between 27 and 75 years old were interviewed, but only three of them were selected to be included in this monograph, based on their biographies and oral history contents. The interviewers’ narratives show elements of women's human ecology in an Amazonian riverine context, at the same time that reveal women's perception and knowledge about ecology, landscape, history, environmental changes, among other related topics.

Sex, sexuality and disability are complex phenomena, present in everyone's lives, but manifesting themselves in different ways. These phenomena are permeated by knowledge and powers and can motivate episodes of aggression. Sexual violence is any sexual act that involves coercion, intimidation, threats or blackmail, and is carried out without the consent of the other person. Sexual exploitation is the forced involvement of minors in situations of prostitution or forced marriage. There is a high incidence of this violence today, especially among female adolescents, however there are few studies that investigate this violence aimed at people with disabilities. This gap in Brazilian scientific production prompts questions to Brazilian researchers and unfolds in research possibilities, such as the vulnerability of people with disabilities to situations of sexual violence and their knowledge about violence, sex and sexuality. Thus, the general objective of this research was to investigate the vulnerability of young people with intellectual disabilities in the face of situations of sexual violence and to identify the knowledge of these young people and their guardians and teachers about sexuality, sex, sexual violence and its prevention. Quali-quantitative methods of data collection and analysis were used. Initially, the “What if – Situations test” instrument was applied to nine young people diagnosed with intellectual disabilities residing in the interior of the state of São Paulo to investigate their vulnerability to situations of sexual violence. Semi structured interviews were also carried out with these young people, their guardians and their teachers, addressing topics about sex, sexuality, sex education and protection from sexual violence. The collected data were systematized and analyzed qualitatively using genealogy under a Foucaultian understanding. The results showed that young women demonstrate considerable vulnerability to sexual violence, with difficulties in recognizing situations that indicate danger and in acting in the face of these situations. Their responses to situations of danger were permeated by social constructions of gender, approaching socially required performances of the male and female gender. The speeches of the guardians circulated about the overprotection of their children, constituting a system of surveillance and control of the body, and in infantilizing and asexual notions of disability. The teachers also noticed these speeches by the guardians, and they try to do orienting work with the students, however their performance is permeated by the control and surveillance of the body and by the hypersexualizing discourses of disability. Both teachers and guardians say they do not work on preventing violence with young people, giving vague and not very assertive guidelines on sexual violence. The intersection between the studies of sexuality, violence and disability is an unexplored field, however rich in contributions to professional practice and to the fight against violence. It is hoped that this thesis has contributed to these questions.

The concern of international bodies regarding sustainable consumption and production is growing due to the environmental impacts caused by humanity, and the constant governance of production processes is extremely important. In this context, this work proposes a sustainability indicator for monitoring and directions for the mitigation of environmental impacts caused in the production of friction materials, an industry highly harmful to the environment. For this, a research divided into four phases was carried out, in the first, a systematic review of the literature in international databases covering 1,573 articles. In the second phase, based on a deep content analysis, it was observed that the existing indicators, although they have general similarities, such as the evaluation of social, environmental and economic factors, lack external validity due to the singularities of the industries. indicator adapted to the industry studied. In the third phase, using the action research method for the application and practical validation of the indicator developed, identifying the critical points of the object of study. After applying operational research techniques and statistical analysis, according to phase four, important results were achieved, such as the reuse of 240 tons per year of materials previously considered waste, in addition, the decrease in the rate of harmful materials used in products fell from 24 .2% to 17.41%. In this way, the present work contributes to the refinement of the theory and the practical validation of sustainable metrics in the specific context of the friction materials industry, bringing to this context a tool for directing the improvement of this environmentally harmful industry.

In order to achieve a sustainable production, in a sector where the demand for natural raw materials is very high worldwide, this project aimed to explore the feasibility of increasing the addition of recovered materials in castable refractory for application in main runners, as well as exploring the addition of a recovered material previously not used for this application, in order to reuse diversified refractory waste and save raw materials. The work focused on investigating the impact of increasing the addition of torpedo car chamotte (Al2O3-SiC-C) to 10%, as well as analyzing the addition of 10% of a new material: AZS chamotte (Al2O3-ZrO2-SiO2), to Al2O3-SiC- C based castable. This refractory is widely used in main runners due to its good properties of resistance to carbon oxidation, thermal shock, but mainly, resistance to pig iron and slag attack. Therefore, studies and packing adjustments were performed using the EMMA (Elkem Materials Mixture Analyzer) software, with the goal of obtain a higher efficiency in the replacement of the original raw materials of the castable, by the material to be reused, in order to obtain an adequate accommodation of the particles and, consequently, a packing as close as possible to the original castable. Thus, it was sought to obtain apparent porosity levels similar, or even lower than those of the original castable, in order to obtain adequate properties of mechanical strength, corrosion and oxidation resistance. Besides the packing study, used as an initial tool, an analysis of the castable raw materials was also performed, using data analysis in Python, aiming to optimize the flow properties of the material with the addition of the recovered materials. Thus, the influences caused in the properties of castable refractory, due to the addition of these recovered materials and the changes that were necessary during the packing adjustments were investigated. Even with the increased content of recovered materials, it was possible to obtain high fluidity, reduced apparent porosity, reduced carbono oxidation of the material, as well as wear to the attack of pig iron and slag close to those obtained with the original castable.

This work seeks to contribute to the classification of Weingarten surfaces. More precisely, it fully classifies three families of surfaces (named tubular, cyclic and canal surfaces) in a tridimensional space form (Euclidean, Lorentzian and Hyperbolic spaces) that verify an arbitrary polynomial relation among its Gaussian and mean curvatures. The results obtained provide geometric features of the surface as well as algebraic conditions over the polynomial that defines a surface as Weingarten. Furthermore, results that allow us to investigate Weingarten surfaces only by the polynomial analysis are presented.

El objetivo de esta investigación es presentar siete debates y asuntos en controversia que se despliegan en Argentina, Brasil, Colombia y Chile, durante el periodo 2010-2018. Estos países tienen una participación activa en los debates dentro de la región, cuentan con los programas más antiguos de la región, tienen un número mayor de terapeutas ocupacionales, existe una mayor institucionalización académica tanto en el pregrado como postgrado y hacen circular revistas de terapia ocupacional de larga data y libros sobre terapias ocupacionales con autorías colectivas nacionales y transnacionales. El abordaje metodológico de la investigación es de tipo cualitativo con un enfoque de análisis social del discurso, se utilizó el mapeo de controversias a través de la revisión y análisis documental. Es posible identificar dos grupos de debates: en el primero se encuentran aquellos que discuten las prácticas de las terapias ocupacionales en torno a lo social, en torno a las comunidades y los territorios, en torno a género y feminismos y en torno a América Latina y el sur. En el segundo grupo de debates, se encuentran las prácticas de las terapias ocupacionales en torno a los derechos humanos, en torno a los saberes y la producción de conocimientos y en torno a lo crítico. Es posible concluir que existen controversias que expresan diferentes modos de actuar y concebir el mundo, cada uno condensa experiencias del vivir cotidiano desde el cual se van hilando formas plurales e inacabadas de hacer terapia ocupacional. Las controversias que emergen dan riqueza y heterogeneidad a la profesión/disciplina, permiten tensionar las asimetrías de poder y la relevancia política de las prácticas que se producen desde América Latina.

herapeutic itineraries seek to analyze the individual and collective resources that an individual uses to seek answers to their health problems. Therefore, having knowledge about the therapeutic itineraries of a population can be very beneficial in understanding how the health network in that territory is functioning and what its weaknesses are. Thus, the present study falls within the field of qualitative approaches, with the objective of investigating and describing ways of (dis)articulation of the Psychosocial Care Network (RAPS) of São Carlos - SP, based on the therapeutic itineraries of users of this network . To this end, data collection and production was done online through semi-structured interviews. One user from each Psychosocial Care Center (CAPS) in the city participated in the study: a CAPS for alcohol and drugs, a CAPS II and a CAPS for children and youth, their respective companions and professionals, totaling eight participants. The interview data were processed based on the thematic content analysis technique, allowing the production of analytical categories linked to each other. The main results show that there is a gap between the RAPS points, with little articulation of shared care, especially in relation to basic care and with a vacuum in the care of children and adolescents; there are difficulties for CAPS in elaborating and developing care in the psychosocial model, especially in acute situations of psychological suffering, when the local RAPS uses asylum strategies such as hospitalizations and excessive medicalization. As possible responses to these difficulties encountered, we have the training of professionals, the strengthening of continuing education, the presence of managers engaged with mental health, care for workers' mental health and actions that encourage the participation of civil society.

Robotic manipulators are increasingly present in current industrial activities. They are used in tasks such as: painting, drilling and welding operations, material handling, etc. Although these robots are widely used, their tasks are often not performed optimally. There are different characteristics that can be used to define the optimization of a manipulator, such as manipulability, torque, energy, conditioning, among others. Task space redundancy occurs when the end-effector has more degrees of freedom than the task needs, so it is possible to optimize performance using the excess degrees of freedom. This excess of degrees of freedom defines a problem with infinite solutions for the robot joint positions. Defining these positions through an optimization process is called redundancy resolution. There are two types of resolution: local and global. The local observes the gradient of a cost function at each instant of time and decides the joint positions from that. The global one observes a cost function throughout the task execution period to define these positions. Therefore, this work aims to study a planar serial robotic manipulator using task space redundancy to optimize its dynamic performance in order to compare the different redundancy resolution methods. The local and global methods were compared with each other and with the performance of a non-redundant robotic manipulator. In addition to this analysis, the impact of other factors on the optimization of dynamic performance was studied, such as the initial orientation of the end-effector and the use of a weighting factor for gravitational forces in the dynamic equations. The manipulator implementation, simulation and optimization were done using the software MATLAB. The results obtained indicate that the resolution of the redundancy by the local method presented a better dynamic performance and that the joint optimization of the initial orientation and of the weighting factor of the gravitational forces collaborates for this.

Sustainability has become a growing concept in contemporary society. Namely the application of alternative materials in civil construction has increased considerably, like concrete reinforced with vegetable fibers. Actually, Brazil is one of the largest grain producers in the world, which directly implies the generation of agricultural and industrial residue. It is estimated that in the 2021/2022 period of corn harvest, Brazil produced about 264 million tons of corn residues, like cornstalk that through previous treatments, provide the removal of impurities from the fibers and corroborate to increase improvements in the characteristics of resistance to cracking, impact and compression of concrete reinforced with vegetable fibers. Therefore, the present project objectived to analyze influence of the cornstalk fiber in concrete, through the specific mass and resistance to axial compression determination. For this, corn fibers has been submitted to the pull-out test to determine its critical length. Furthermore, corn fibers underwent a heat treatment in boiling to remove impurities and sugars, as well as, any residues from the harvest. The specimens has been molded with different percentages of fibers for a better spectrum of analysis, being them 0% (control), 2%, 6% and 10% and based on NBR 5738: 2003. The tests performed has been conducted based on the respective regulations: NBR 5738 and NBR 5739. Due to the COVID-19 pandemic, tests of 10% composites were not performed. However, the 6% fiber specimens showed an average compressive strength of 36.5 MPa while the control 29.7 MPa. For the specific mass, the variations determined were not significant, with a slight reduction in the same with the addition of fiber. It is concluded that, fiber reinforced concrete shows great potential for application in civil construction.

Sarcopenic older adults are at greater risk of falls, hospitalization, death, diminished functional and cognitive capacity and a poorer quality of life compared to non-sarcopenic older adults. The aims of the present study were to analyze factors associated with health-related quality of life (HRQoL – total and domains) in community-dwelling sarcopenic older adults and determine possible differences in the perception of HRQoL among these individuals before and during the COVID-19 pandemic. Two studies were developed. The first involved data from a previous study with 54 and 117 older adults with and without sarcopenia, respectively, according to the European Working Group on Sarcopenia in Older People 2. The Short Form Health Survey (SF-36) was used to assess quality of life. Comparative and linear regression analyses were performed. Differences between groups were found regarding health conditions and the perception of HRQoL, with worse outcomes among sarcopenic older adults. Perceived HRQoL was poorer in the sarcopenic group compared to the non-sarcopenic group in the following SF-36 dimensions: physical functioning (<0.001), physical role functioning (<0.029), general health state (p<0.001), vitality (<0.011) and social role functioning (p<0.001). All models related to HRQoL in sarcopenic older adults were statistically significant, with the best prediction related to physical functioning (83.3%). The factors associated with low HRQoL were being married (p<0.001), being widowed (p<0.022), depressive symptoms (p<0.007), anxiety/depression (p<0.005) and pain (p<0.009) in the general health state domain; nutritional status (p<0.045) in the social role domain; and depressive symptoms (p<0.005) in the mental health domain. The second study compared the HRQoL of sarcopenic older adults before and during the COVID-19 pandemic using the Sarcopenic Quality of Life (SarQoL®) scale. For the pre-pandemic period, a databank was used with information collected at the homes of the older adults. During the pandemic, the same individuals were interviewed by telephone. Interviews lasted an average of 15 minutes. Half of the older adults felt vulnerable to contamination by SARS-CoV-2 (p<0.001), felt some or considerable fear (p<0.013), a minority felt isolated and a reduction occurred in activities of daily living (p<0.001). No differences were found in the comparison of the pre-pandemic and pandemic period regarding the perception of overall HRQoL or any of the dimensions, with the exceptions of locomotion (p = 0.013) and body composition (p = 0.005). In conclusion, older adults with sarcopenia had poorer HRQoL in all domains of the SF-36 compared to the non-sarcopenic group, except for the bodily pain, emotional role functioning and mental health domains. Being married, being widowed and having depressive symptoms, anxiety and pain were associated with poorer HRQoL in the general health state domain, nutritional status was associated with the outcome in the social role domain and depressive symptoms were associated in the mental health domain. Unlike what was expected, no differences were found for the majority of HRQoL domains evaluated using the SarQoL® scale before and during the pandemic among sarcopenic older adults. These findings are important to the planning of care for older adults in the primary care context.

Servitization and digitalization are trends that have generated changes in manufacturing companies. From the convergence between them arises the concept of digital servitization. Digital servitization is understood as the use of digital technologies in servitization-related processes and offerings. Like servitization and digitalization, digital servitization, to varying degrees, requires reconfiguring the business models of manufacturing companies. The literature points to digital servitization as a process of organizational change that can be understood by the factors that lead to this change (context), the factors that need to be transformed (content), and how the change is processed (process). Therefore, it is relevant to understand digital servitization from a holistic perspective and to understand how it unfolds throughout its implementation. Therefore, this thesis has the general objective of developing a model that describes the transformation process of manufacturing companies towards digital servitization. For this purpose, a multi-method approach was used that brings together several research methods such as systematic literature review, research with experts, and multiple case studies. Furthermore, the thesis was organized in the form of articles, which summarize the main results achieved: (i) identification of challenges in digital transformation from the perspective of the business model; (ii) an account of how digitization fundamentally transforms manufacturing companies in their transition to services; (iii) clarification of the transformation process to digital servitization in manufacturing companies from the perspective of experts and, (iv) understanding of how the journey to digital servitization in manufacturing companies unfolds from case studies. The integration of results allows the description of the transformation process for digital servitization in manufacturing companies. In this sense, a conceptual model was proposed for the digital servitization process. In terms of theoretical contributions, this thesis contributes by (i) discussing the challenges faced by manufacturers in the search for innovation in business models through digital transformation; (ii) presenting a conceptual model and propositions capable of providing a broad view of how digitalization imposes changes in the traditional dimensions of servitization; (iii) demonstrate the factors that impact the transformation process to digital servitization and their interrelationships; (iv) reveal how the journey to digital servitization unfolds from the analysis of two cases and, (v) develop a theoretical-conceptual model for the transformation process of digital servitization. As a practical contribution, the results guide managers that can be used to guide or improve the process of implementing digital servitization in their companies.

Considering the increase in the number of allergy cases related to products originating from milk, it is necessary to develop products with rheological and sensory characteristics similar to conventional products, replacing animal protein with a vegetable base to include this food in the population's diet allergic. Knowing that cottage cheese is a food present in Brazilian cuisine, it is estimated that there will be demand fortheproduction of the new product. Thus, it is reported the development of a requeijão food of vegetableorigin based on manioc, which is totally free of lactose and casein. For this, three differentformulations were elaborated, and sensorial analyzes were carried out by the triangular test in order to find the closest formulation to conventional cream cheeses. Rheological analyzes were also performed using rotational rheometry, in order to achieve the characteristic fluid profile, analyzing the behavior of the shear rate curves as a function of the shear stress of the formulations. However, it was found that formulation three was the closest to commercial requeijão, both sensorially and rheologically. However, other formulation tests would be carried out to correct aspects pointed out by the panelists, such as residual cheese flavor and viscoelastic texture, which were not performed due to lack of time.

This thesis presents an ethnography of the cerrado with the women who live in the sertão das veredas, geographically located in the northwest of Minas Gerais state (Brazil). Walking, knowing, and writing the cerrado together with the women's mexidas is the main task of this work. Its main argument follows the idea of reparar as cores [repairing the cerrado colors], an expression often used in the sertão das veredas that express the variety of forms found in the colors of the landscape. This thesis is attentive to the ordinary practice, to everyday relations among rural women and the contrasts between the poverty of development and the riqueza [wealth] in the cerrado. It is about the relation of time and the abundance that comes from the variety of collective practices of economic organization. Likewise, it focus on the nuances of the women's adherence to development projects, and the way they create difference and wealth, in contrast to the pecuniary quantification of the cerrado. It also discusses the various ways people establish prices in very particular economic transactions. Finally, it deals with the color of pigmentations that, in face of lived experiences amid the transformations of the land, the waters, the wind, the flowers, the landscape, paint an image against the secamento do tempo [the drying of time] in the cerrado.

The no-code development trend, also known as no-code or low-code, has gained popularity for its ability to speed up the development process and allow people with no programming experience to create solutions in a simplified way. A solution that fits this trend is the Block based Integrated Platform for Embedded Systems (BIPES), a platform for developing embedded systems based on blocks, designed to make it easier to create electronic projects without the need for advanced knowledge in programming. With BIPES, users can create programs to control electronic devices by combining pre-programmed graphic blocks that perform specific functions, without the need to write code. The platform is compatible with several popular microcontrollers, such as ESP8266 and ESP32, and offers a user-friendly graphical interface to facilitate the creation of programs. To meet the needs of users already familiar with databases, blocks were developed for sending data from ESP32 to a MySQL database. These blocks were created to help collect analog and digital data read by the ESP32 and send this data to a MySQL database through a PHP code that communicates and processes the data. With the use of these blocks, it is possible to collect data in real time from the ESP32 and store them in a database, allowing this data to be analyzed later and used for different purposes. To validate the effectiveness of the blocks for sending data developed in BIPES, a DHT11 sensor connected to an ESP32 board was used. The sensor was used to collect temperature and humidity data from the environment, and the blocks were configured to send this data to a MySQL database. Throughout the validation process, it was possible to confirm the functionality of the blocks and the correct communication between the ESP32 and the database, allowing the collection and storage of data in real time. Block validation was an important step to ensure the reliability and efficiency of the system for sending data to MySQL databases developed at BIPES.

With the development of the country, the demand for electric energy tends to grow, with estimates pointing outgrowth of more than 100% until 2025. Currently, in Brazil, one of the main sources of energy is hydroelectric power. Due to the recent climate change and water crises in the country, investing in alternative sources is necessary to avoid energy crises. One of the actions to reduce greenhouse gas emissions, given the agreement set in Paris, in 2017, is the increase of renewable energy. Among the sources, taking into account the potential for solar incidence in Brazil, the installation of photovoltaic solar power is an alternative that should be considered. Defining the best areas for implementing these, using environmental, technical, and economical criteria is important to optimize the use of available areas and increase energy efficiency. The main variables used in this study and their prioritization were defined from a bibliographic review. With the combination of the criteria and the processing in Geographic Information System (GIS) tools, the map of the priority areas for the installation of solar photovoltaic plants for the State of São Paulo was presented. It was identified that the north region of the state have a high degree of aptitude, while the southern region had the lowest, for the implementation of this type of business.

Access to food is one of the principles of food security, which is presented as one of the premises for promoting the dignity of the human person. The guarantee of food security and the human right to adequate food (DHAA) guide the policies developed by the public administration, whose aim is to promote social security. In this context, ensuring continuous food supply, guaranteeing access to food, is the main objective of the State's action mechanisms. The Minimum Price Guarantee Policy (PGPM) is one of the policies aimed at this purpose, as it works to correct market failures, promoting income for farmers and affordable food prices for consumers. However, although the State's action is regulated in this regard, there was a considerable increase in the price of basic food items during the COVID-19 pandemic established in Brazil and around the world. Among them, rice (Oryza sativa L.) stands out, whose price rise directly affected the basic diet of the poorest Brazilian population. Therefore, the objective of the present study is to investigate state action and its adequacy in guaranteeing supply and regulating product prices. To this end, information on public and private rice stocks, present in the National Supply Company (CONAB) database, was analyzed. As a result, it was possible to conclude that state management in promoting food security during the COVID-19 health crisis was unsatisfactory. Knowing the scenario of currency devaluation and the consequent increase in exports, in addition to the increase in domestic demand, it was predictable that there would be a market imbalance between supply and demand and an increase in prices. However, the amount of rice stored in public stocks proved to be deficient in relation to national production, not meeting the conditions for intervention to guarantee food security for the population.

This dissertation is exploratory in nature and was divided into three studies. In the first study, an integrative literature review was carried out to analyze the national and international scientific production on disability and violence. For the data search the keywords disability AND violence, disability AND violence and disability AND violence were used in the electronic databases Scopus, Scientific Electronic Library Online (SciELO), Web of Science and PubMed. Initially, 1953 articles were identified, and after applying the inclusion and exclusion criteria, 21 articles were considered eligible for the final sample. Among the studies analyzed, most addressed abuse and disability in general. The data obtained indicated the vulnerability of children and adolescents with disabilities to suffer violence, discussed the risk factors mainly associated with the family environment and children's variables, and the consequences of violence. The second study describes the methodological path of elaboration of a vignette instrument (VIOLETAS - Questionnaire of vignettes on violence against children and adolescents with disability) that followed the stages of construction, based on criteria and scientific recommendations from national and international literature. The instrument aimed to analyze the attitudes of the respondents in face of situations of violence against children and adolescents with disabilities, and was assessed by five expert judges (2 from the violence area, 2 from the disability area and 1 from the law area) and considered the values of the Coefficient of Content Validity - CVC of the judges in relation to parts 1, 2, 3 and vignettes. After the suggested changes, it went through a sample of 20 participants (university students and professionals from the protection network) and after the contributions of the respondents the instrument was adapted to its final version. The third study aimed to analyze the relationship between conceptions of disability and attitudes towards situations of violence against children and adolescents with disabilities. 118 people participated in the research, 41 university students and 77 professionals from the services network (34 from education, 19 from health, 16 from social assistance, 2 from the judiciary, and 6 others). All participants answered an online form composed of the Scale Conceptions of Disability - ECD and VIOLETAS - Questionnaire of vignettes on violence against children and adolescents with disabilities. The analysis of the results indicated that: a) in general there is greater agreement on the part of students and professionals with statements of the historical cultural conception of disability, this data is discussed with the respondents' education and contact with the theme in undergraduate studies; b) most respondents pointed as the first attitude in the five vignettes "Talk to the child/adolescent with disability and/or family" such attitude is considered inappropriate by the literature, because it can cause revictimization, it is discussed that the indicated is to make the notification to the competent bodies; c) regarding the identification of violence and violations of rights, the percentages were high and/or unanimous in the identification of violence and when understood the identification of violations of rights the percentage decreased, it is discussed the inconsistency of this result because it is understood that all violence is a violation of rights, in this discussion it is also pointed out the factors that could prevent the notification of violence; and d) there were no differences in attitudes when understood each of the conceptions of disability. Finally, it is considered that the main contribution of the research was to indicate how emergent investigations in this area are, how important it is to discuss this reality and invest in professional/university training.

This research work sought to analyze the possibility of determining if there is a mathematical relationship of the strength of an alternative concrete as a function of the replacement content of fine aggregate by sandstone, based on the replacement of part of the conventional fine aggregate (sand) by sandstone. The sandstone used in this research project was from the Pirambóia geological formation and substituted part of the aggregate in percentages of 0%, 15%, 30%, and 50% in relation to the total volume of sand. The percentages of 10%, 20% and 40% could not be made due to the UFSCar laboratories being paralyzed by the COVID-19 pandemic. Tests were performed to determine physical density and axial compression, according to NBR 5739. With the test results, it was possible to determine three prediction equations for the strength behavior of sustainable concrete according to the percentage of sandstone used as fine aggregate, being these two equations of grade 1 and 2. Mathematical relationships between physical density and compressive strength were also observed. The importance of this work is due to the optimization of the use of sandstone in the concrete mixture according to its employability

Since March 2020, Brazil, like the whole world, has been facing a major pandemic caused by COVID-19 (SARS-CoV-2). COVID-19 is a highly transmissible respiratory infection and for this reason governments around the world have taken health measures to control cases of the disease and thus stop the pandemic. The lockdown was a sanitary measure used in some cities to prevent the movement of people on the streets and thus reduce the contamination of people with the disease. In addition, after almost a year since the beginning of the pandemic, some countries have started to apply vaccines as well in order to reduce the impacts of the pandemic. Faced with the uncertainty about what would actually be effective to control the number of cases and deaths from COVID-19, researchers and people of common sense began to be interested in these sanitary measures and began to question whether the lockdown or if the start of vaccination helped to control the pandemic. In this context, this work studied the effects of lockdown and vaccination on the number of new cases and the number of deaths by COVID-19 through time series techniques. After applying the methodology, we observed that the lockdown helped to reduce cases of COVID-19 in the city of Araraquara and that vaccination impacted the reduction of cases and deaths.
