The business plan aims to demonstrate the feasibility of a monolithic panel factory, located in Cravinhos-SP. These panels are considered the evolution of conventional masonry, that is, they efficiently replace bricks. While our competitors practice on average, values of R$ 150.00/ m², Trêss Panels will practice on average values of R$ 85.00/ m² for Constructors and Houses of Construction Material. Considering an investment of BRL 12,000,000.00, the company, through its earnings projections, would take approximately 8.5 years for payback, with an internal rate of return of 13.06%. The company's average ROI over 5 years is set at 12.46%. Considering that civil construction is on the rise, having grown by 4% in 2021, the moment is for the insertion of a new construction method, which is beneficial for the environment, for the builder and for the customer. For the environment through sustainable features, for the builder through lightness and speed, and for the customer through comfort and mostly through savings in financial resources.

Numerous evidences in rodents indicate that caudal brain regions, such as the raphe, are involved in the activation of production effectors (tremor-dependent and tremor-independent thermogenesis) and conservation (peripheral vasoconstriction) of thermal energy. On the other hand, in birds, which had an evolutionary trajectory for acquiring endothermy totally separate from mammals, this scenario of neural regulation of body temperature is not clear. Therefore, the present study aimed to investigate the participation of medullary raphe in the activation of thermoeffectors of cold (thermogenesis and peripheral vasoconstriction) and heat (dry and evaporative heat loss) in chicks in the first week of post-hatch life. For this, body temperature, oxygen consumption (thermogenic index), pulmonary ventilation (thermal tachypnea to heat or hyperpnea to cold) and dry heat loss index (from skin temperature) were measured in animals with inhibition and activation of rafe and subjected to cold (26°C), heat (36°C) or neutral environment (31°C). Inhibitions and activations were performed with local microinjection of GABA and NMDA glutamate receptor antagonists. And the results indicated the existence of glutamatergic and GABAergic excitatory influences on the medullary raphe of chicks modulating thermogenesis, and glutamatergic stimulation preventing tachypnea, without having any role in the defense responses to heat. Since the raphe is the main serotonergic region of the brain, the participation of serotonergic neurons in this region in the thermoeffector responses of chicks exposed to cold and heat was also verified. However, analysis of the activation of chick medullary raphe neurons showed that they are activated in the cold (increased expression of c-Fos) and are involved in thermogenesis, but do not appear to be those that synthesize serotonin, since a low percentage of neurons serotonergics expressed c-Fos and there was no effect of serotonergic neuron-specific injury on thermoeffector activity. In addition to serotonergic neurons, the medullary raphe of chicks was also shown to have GABAergic neurons, and the lesion of these neurons affected Tc, O2 consumption, and influenced the ventilatory pattern under cold and thermoneutral conditions. Thus, the results indicate that, unlike in mammals, the modulation of thermogenic and ventilatory responses to cold by medullary raphe in chicken chicks does not involve serotonergic neurons. Among other phenotypes of neurons possibly involved in this neural modulation, we evidence a role for GABAergic raphe neurons. Such results open a new perspective related to the neural regulation of body temperature in endothermic vertebrates.

The expression sexting is used to denote activities that involve sending text messages, images and videos with sexual content and/or intimate images. Although the practice of sexting is a contemporary expression of sexuality and does not represent, a priori, a risk factor for the development of adolescents, there are risk factors associated with its practice. The exposure of intimate images in a non-consensual way appears as one that brings suffering to the lives of children, who are mostly women. As it is a dangerous phenomenon, images of intimate exhibition complexes with teenagers can be delivered. This occurs, between the difficulties of access for the victims and the possibility of re-victimization of the adolescents, which can be verified on the coerced with research teams. Based on these findings, this dissertation was organized into two articles. In Article 1, we study how adolescents are themes presented in a collection of com, especially in data studies that involve sensitive data, a research modality that involves the collection of adolescents in digital format. In important hypotheses, it is known that as video platforms, teenagers were allowed to share their stories in the way they felt most appropriate and convenient. Some of the teenagers were informed this time for the first time that they had addressed the matter publicly. The fact that teenagers have the opportunity to edit the videos is also relevant, as it allows them to reflect on the content they produce and share what they really want, exercising a leading role. Also, by recording the videos in spaces they choose and feel, they enable spontaneity and authenticity, the fundamental requirements in research. In Article 2, we sought to analyze protective factors and nearby resilience processes in adolescents who had images released in a non-consensual manner. For this, videos of teenagers residing in Brazil and the United States were selected who had their intimate images released without consent and who voluntarily published their reports on an online video platform. This was a qualitative, exploratory-descriptive case study, based on a multiple study. After defining the reports of teenagers presented on the YouTube platform, 15 videos were selected, 9 videos with reports of teenagers in the United States and 6 videos of residents in the United States and 6 videos of residents in Brazil. Data was analyzed using computer techniques. 3 topics were reported in Article 2, namely: (i) Interfaces between and protection; (ii) “This made me who I am”: Resilience Processes experienced by adolescents; (iii) ‘No face, no story’: Protagonism and Harm Reduction Recommendations. Both articles are released and disseminated for the scientific advancement produced in the area.

This work aims to understand the dynamics of interpersonal relationships experienced by women and other people from different family nuclei, and, thus, bring their views on their bodies and the female, from the transmission of knowledge between generations. It is intended to understand how the construction of gender identities from the family nuclei takes place, considering “gender” as a social and historical construction and of education for the female as a learning process. From this, the intention is to bring elements about the different origins and different traditions and cultures that women translate through memories. It is concluded from the research that the perceptible cultural changes from one generation to the other point to the possibility of establishing more democratic and egalitarian relationships between women. Therefore, the method used was the collection of oral reports, through semi-structured interviews, with 10 women belonging to three different family groups and from different generations: granddaughters, daughters, grandparents and great-grandparents.

Constructive Design Research (CDR) aims to produce design knowledge through experimentation and debate within the academic community about the process of designing and evaluating an artifact. However, many studies in this area neglect important details when reporting the methodology and procedures used, as well as the context and justifications for the decisions made in both design and evaluation, negatively affecting the contribution of these studies in a theoretical and practical sense. This neglect is due to the lack of structure, clarity, and objectivity of the documentation. In this context, this Ph.D. thesis proposes a framework called Lean UX Research, composed of a process model associated with a set of guidelines that help the production of scientific knowledge through more focused design research with an artifact and a more concise and structured CDR. This framework extends the Lean UX methodology, an iterative process of creating, validating, and reflecting on prototypes to find a solution to complex problems based on agile methods. Thus, the model and guidelines allow researchers to situate themselves in the CDR, selecting the most appropriate methods and tools at each stage. The formalization of this framework involved a broad literature review of design processes and design research, and agile methods applied in design and documentation to be grounded in the theory and state of the art of existing practices. To evaluate the framework, an inspection by experts was carried out, which resulted in its refinement, establishing a methodological framework that supports design and research equally, while avoiding unnecessary documentation. Thus, as a product of better documentation of the design research process, it is possible to build and refine theories, methods, and tools. Furthermore, the adoption of research programs in this framework will allow research to progress in a more linear way, consolidating Design as a discipline and a research practice.

Advances in technological, economic and health conditions have increased the life expectancy of human beings. Currently, the number of older adults is approximately 1 billion worldwide according to the World Health Organization. One of the major concerns of the older population is the falls risk. In Brazil, the prevalence of falls in 2017 ranged from 10% to 35% in older people living in urban areas. Falls generate high expenses for public and private health systems; have harmful consequences for the physical and mental health of the older adults, such as fractures, injuries, injuries, psychological consequences, such as fear of falling again, loss of confidence and social isolation, in addition to institutionalization, increase in emergency room visits and long-term hospitalizations. Case management seeks to identify the problems and conditions that can change for the older adults individually in order to meet the needs found, this model of care associated with the health care plan is able to offer physical, psychological and social assistance that goes beyond the traditional models of health care. Therefore, this dissertation aimed to evaluate the influence of case management applied to a fall prevention program in order to reduce the risk of new episodes of falls in the older adults. The dissertation was divided into two studies. Study 1 “A Case Management Program at Home to Reduce Fall Risk in Older Fallers: a Single-Blind Randomized Controlled Trial Protocol (Magic Study)”. Objectives: to describe the protocol used in a single-center, parallel-group (Intervention Group and Control Group) and single-blind (evaluators) randomized clinical trial involving a case management-based fall prevention program for older adults who had suffered 2 or more falls in the last 12 years. months. Methods: Community-dwelling older adults will be volunteers and will perform an initial assessment by video call and will be randomly allocated into one of 2 groups: intervention group or control group, volunteers from the intervention group will be invited to participate in the 16-week intervention with physical activity and management risk factors for falls at home by telephone and video calls, the volunteers in the control group will maintain their usual routine, after 16 weeks all will be reassessed by video call. Results: To date, 52 older adults have been recruited for the study. Study 2 “Influence of case management in a fall prevention program for the older people on functional variables: Randomized Clinical Study”. Objectives: To assess the effects of a case management-based fall prevention program on postural balance, functional capacity, presence and sites of pain, falls risk, and risk for osteoporotic fractures over the next 10 years in community-dwelling older adults who suffered 2 or more falls in the last 12 months. Methods: Sixty-two community-dwelling older adults volunteers underwent an initial assessment by video call, after which they were randomly allocated to one of 2 groups: intervention group or control group, volunteers from the intervention group were invited to participate in the 16-week intervention with physical activity and management of risk factors for falls at home by telephone and video calls, the volunteers in the control group maintained their usual routine, after 16 weeks all were reassessed by video call. The evaluators were blinded to the randomization and allocation of volunteers in the groups. Results: There were significant differences after the intervention in the improvement of functional capacity and balance evaluated by the Up and Go Test in the Control group. There were no other significant differences in balance, functional capacity and lower limb strength and in the presence of pain among the volunteers. Conclusion: The association of case management in a program for the prevention of falls in older adults fallers in the community did not present significant results in the functional variables, but it was important for the characterization of pain and fracture probability for the next 10 years in this population.

The slim floor systems are characterized by partially encased beam, usually asymmetrical steel profile, configuring a partially encased composite beam. This research aims to evaluate the structural behavior of partially encased composite beams with concrete hollow core slabs and steel cellular profile, under flexural condition. The main aspects evaluated were the flexural strength and failure modes. Numerical modeling of 46 partially encased composite beams under bending tests was developed in ABAQUS® software. Numerical models and procedures were validated from experimental tests of partially encased composite beams in slim floor systems published by several researchers. The main parameters evaluated were the diameter of the reinforcing bars, steel web and flange thicknesses, diameter and number of web openings in cellular profile, concrete topping thickness and the width of the slab. The numerical study revealed the contribution of reinforcing bar in the resistance of the steel-concrete shear connection and consequent increase of the bending resistance. The increase of the steel web and flanges thickness resulted in a significant increase in the strength capacity of the composite beam and reduced values of web thickness compromise the section capacity. The increase in the width of the slab and concrete topping thickness, the composite section presented increased strength and stiffness. Increasing the diameter of the web openings significantly reduced the stiffness and strength of the composite beam. In addition to the numerical program, an initial analytical model was developed to determine the bending moment. The results of the numerical analysis were compared with the equation proposed to determine the bending moment. The analytical model demonstrated coherence and satisfactory correlation with numerical results, and efficiency of the infill concrete in circular openings in the encased steel beam as a shear connector.

This study proposes to identify and analyze how the work of the teacher in the resource room happened, observing the limits and possibilities in the context of the physical distancing in the year of 2020, when, due to the COVID-19, infectious disease that spread through different continents in a very short amount of time, and following the general orientations of the Opinion 05/2020, it was assured to the target students of the Special Education the non-presential teaching. This way, the study was guided by the question: how was the resource room teacher's work organized and applied during the non-presential teaching in the year 2020? Seeking to answer the research problem, it was developed with the general objective: identify and analyze the organization and the teacher's work functioning in the resource room in the basic education of the Brazilian public system in the year of 2020. Also, as specific objectives: a) identify and analyze official national documents and external directions that guided the non-presential teaching in this year; b) characterize the proposals for the work of the resource room in the non-presential teaching; c) point and analyze the proposal of non-presential teaching, in the year 2020, in the teachers' pedagogical practice in the resource room. The present research, of qualitative character, is characterized as a descriptive study. The data collection happened from an online questionnaire with open and closed questions. From the participation of 55 resource room teachers who acted in the non-presential teaching in 2020, it was possible to identify three axes of analysis. 1) planning and digital resources – formation for the non-presential teaching; 2) the contact with the students: the family participation; 3) the resource room teacher's work articulation along with the common teaching teachers and school management. The results of this study showed that the shortage of resources, the lack of internet access and formation to use these resources, on the teachers’ side and also on the students’ families’ side, could be characterized as disadvantage factors for the resource room teacher's work development. The results also highlighted that the articulation with the families (support) and the common teaching teachers highly contributed to the resource room teacher's work durin the emergency teaching model.

Notwithstanding the psychosocial exclusion practices of LGBT workers (lesbians, gays, bisexuals and transgenders) from the world of work, verified to the present day, there is a counter-hegemonic movement of inclusion, through few, but significant, actions from international organizations, public authorities and even by the private sector. Despite the prejudices and violations experienced at work by LGBT people, this is still represented by them as a tool and means to overcome some barriers and assert themselves as social subjects. Faced with the paradox of pain and delight of being "LGBTWorkers" and at the same time there is also a growing and even active search for workers who do not fit the heteronormative standards to compose the staff of large organizations, there is a need to better understand the existence (or not) of correspondences between the values of the management system, expressed by the business discourse, and the organizational practices of the referred companies. This research aimed to evaluate how, in fact, the inclusion policies for LGBT workers, practiced by an organization that, avowedly, positions itself as inclusive and diverse are implemented. I adopted a qualitative method and carried out a case study, through direct observations, semi-structured interviews and survey of official documents. The information obtained from the field was analyzed through triangulation and made it possible to verify that the company studied, in fact, did not have diversity policies concretely implemented. It carried out few and punctual awareness actions to minimize tensions between LGBT workers and other workers, however, without setting real inclusion goals, mainly, for transgender people. a Corporate Social Hypocrisy, in the form of Rainbow Washing.

Candomblé, the Afro-Brazilian religion, has in Nature its main form of expression; it is the basis of the material, spiritual and religious existence of traditional African-based communities. Thus, in this work, the object of study was the ability to provide ecosystem services of a rural property managed by the Ylê Axé de Yansã community, whose management values harmonious coexistence, conservation and rational use of natural resources. The management of agroecosystems, in its complexity, involves aspects that relate to the natural and social spheres, which influences the provision of ecosystem services. In this sense, the traditions of traditional African-based communities can bring new possibilities for the handling of agroecosystems and the consequent offer of provision, support, regulation and cultural services. In the complex context of Candomblé, where the unity of the human being in the natural environment prevails, plants have an important symbolic value, therefore, in addition to presenting an essential ritualistic role, they help in the characterization of the sacred that promotes the maintenance of their traditions and customs. Chapter 1 assesses the sustainability and ability to provide ecosystem services of the subsystems of a plot managed by traditional African-based community, guardians of Nature, preserve natural resources, value biodiversity, which increases the multiplicity of services offered in each system. And in chapter 2 an ethnobotanical survey was carried out, where the floristic structure of Ylê was discussed, relating the plant diversity used in a wide variety of rites, being this diversity the result of an intense and continuous process of preservation by the community.

In early 2020, the SARS-CoV-2 virus caused a disease known as COVID-19 that caused a worldwide pandemic. As a result, there was an increase in the demand for PPE (masks, aprons, gown, etc.) in the hospital environment. With the growing alarming numbers of infected around the world, WHO recommended that the population also wear masks for their protection, increasing the consumption of this PPE, leading to a shortage of masks in the world market. Within this context, the understanding of the difference between the types of masks and the standards that exist on the characterization of these is very important. Thus, the present work objectives to study the current standards (American, European and Brazilian) and propose improvements in the characterizations of filtering materials. Therefore, this work consists of seeking innovation in the development of protocols to characterize masks. Eight masks were tested, six surgical masks and two respirators, to assess the best way to characterize them. The tests were: determination of permeability, fiber diameter through SEM images, particle filtration efficiency and pressure drop (breathability). These last two tests are carried out using the current standards as a basis. Some changes were made to evaluate the interference in the tests. The combination of filtration efficiency and breathability is very important for the quality of the mask. The permeability tests were consistent with the pressure drop tests, since the mask that obtained the highest permeability was the one with the lowest pressure drop. The results obtained by all surgical masks did not accomplish desired results by the standards, in any test condition. Only the respirators presented results close to what is stipulated by the standard (95%) at the lowest surface speed tested (6,51 cm/s). The standards do not use the correct conditions for the tests, since tests should be performed at speeds that simulate human respiratory activity. An example of this is the fact that the current Brazilian Standard and the American Standard allow a wide range in face velocity (0,5 to 25 cm/s) that do not represent any human activity, since the speed of a sneeze can vary between 20 and 50 m/s, that is, at least 100 times higher than the maximum limit proposed by the standard. The breathing of a person at rest is around 6 L/min. Thus, an ideal flow rate for performing the tests would be flows close to this value. In this work, tests were performed, following the standards, using the flow rate of 7 L/min and the masks did not present good performance, with the best result being close to 56% efficiency in the collection of particles of 100 nm. This low performance can be related to the size of the particles that the tests were carried out, because surgical masks are recommended for use against droplet-transmitted pathogens and respirators (PFF) are indicated for diseases transmitted by aerosols. And since the test was performed for 100 nm particles (aerosols) the surgical masks performed poorly. In general, this work made it possible to evaluate parameters that directly interfere with the results of the tests that are proposed by the technical standards for surgical masks. Concluding that the tests must be reviewed and define better parameters (concentration of aerosol particles, particle size, test flow rate, test area or surface velocity) and define the equipment that must be used according to the counting and classification efficiency of the particles.

Brazil, Mozambique and Portugal are part of the Community of Portuguese speaking Countries (CPLP). They have several general cooperation agreements that involve their educational systems and seek to ensure the educational right and the universalization of education. It is in this context that the present thesis had as its general objective to analyze the programs and government actions in Special Education implemented in Brazil, from 2008 to 2022. The thesis was structured in two studies. The first study aimed to analyze the concepts of Special Education, adopted in the official documents and describe the target audience served by the programs and government actions of these countries. The second study aimed to identify educational programs and government actions implemented for people with disabilities in Brazil and analyze the actions of the Ministry of Education for the implementation of government programs in Special Education. The two described studies were conducted through a qualitative approach, anchored in the documentary research technique. As instruments, in Studies one and two, a Documentary Analysis Protocol was used in Special Education Policies and in the second study, a semi-structured interview script, applied to two representatives of the Ministry of Education. Data from Study one were compiled, described and analyzed based on the Comparative Politics. The data from study two were recorded, transcribed and analyzed by judges, using Thematic Analysis (TA). According to Study One, the results indicated different organizational forms of pedagogical work in Special Education, cultural and political specificities of the different countries. It was possible to verify that the terminologies adopted in the official documents are similar, and the policies, programs and actions were built during this period from the international guidelines of multilateral organizations. The Study is a progressive period that culminated in the reflection of Special Education policies, programs and activities. Such programs and actions began to legally define a type of public to be served, different services and spaces for offering Specialized Educational Assistance. In recent years, after sudden political-economic reforms, Special Education policies began to more explicitly the logic of the market and capital in defining their guidelines and principles. These effects culminated in the publication and subsequent suspension of the legal effects of the National Policy on Special Education: Equitable, Inclusive and Lifelong Learning.

The social medias have gained more and more prominence and importance in the academic environment, being used as a primary source of data or in scientific communication, environmental education (EE), and citizen science initiatives. However, the range and real impact of these initiatives on the public are still unknown. To verify the potential of social networks as a tool for wildlife conservation, an analysis of conservationist profiles present on Facebook and Instagram was carried out. We evaluated their engagement metrics, characterized a sample of their audience and identified the impact of their posts. The data were obtained through active data mining and the application of a structured questionnaire. 201 people who follow the conservationist profiles answered the characterization questionnaire. We found that a very specific portion of the Brazilian population follows the profiles, this portion being composed of young, white, female people with a high level of education. We also observed that more than half of the public sample has a direct relationship with environmental areas. When evaluating the engagement metrics of the profiles, we observed that they have low interaction with the public when compared to the total number of followers. In addition, we observed that video posts had great potential to reach more people. In the present study, almost all the participants (97%; N = 194) stated that the publications made by the conservationist profiles were already responsible for new knowledge or for changing their perception of biodiversity. The data presented here corroborate the importance that social media have in today's society and demonstrate that they can be an important ally for the conservation of biodiversity, but the reach of posts to a very limited audience is a problem to be overcome.

The present research has as general objective to analyze the ways of survival and work of the subject João Francisco dos Santos, the Madame Satã during his life. Through documentary and bibliographic research, it is possible to seek the voice of Satan in the first person, so that he can tell us about his paths, supported by his interviews and his autobiography. From this path, the research questions arise: “How can a subject like João, black, ex-enslaved, living in the then federal capital, build his survival through work?” and “What possibilities can there be for a black, illiterate and marginalized body to tell their own story?”, from which arises the hypothesis of Satã-Griô, the teller of his own story. Satã, at the crossroads of life in the face of structural racism, gains space within his human condition in the search for dignity, and becomes a rogue, cook and artist. From the observation, deep and sensitive listening of this subject, we can see who the subject João was, and in what his story speaks to our history as a nation.

Semi-insubordinate constructions (SIC) are reported by Van Linden and Van de Velde (2014) as constructions formed by an initial constituent followed by a noun clause introduced by the connective ‘that’. The initial constituent acts at the level of a matrix clause and expresses an attitudinal assessment of the speaker about the propositional content of the noun clause. This dissertation presents a characterization of the forms and meanings of Brazilian Portuguese semi-insubordinate constructions (BP-SIC) and a proposal for a constructional network of these constructions, based on the analysis of corpus data. Supported by the theoretical assumptions of the Construction Grammar that constructions are conventionalized pairings of form and meaning and that syntactic structures carry meaning themselves, the present analysis seeks to confirm the hypothesis that the BP-SIC belong to a hierarchical network of semi-insubordination and share the abstract form of a schematic syntactic construction, [[X] [que] [finite noun clause]], as well as its evaluative meaning. The [X] component represents the construction’s matrix, an open slot to be filled with an evaluative adjective, noun, adverb or interjection. The connective que has its position fixed and introduces the other open slot of the clause, to be filled by any finite noun clause, carrying the evaluated content. Data collection was carried out in the Web/Dialects set of the Corpus do Português (DAVIES, 2016), a written, synchronic, morphologically annotated corpus, composed of texts from 21st century internet pages, whose portion of the Brazilian variety contains more than half a billion words. The constructions were located in the corpus via search expressions with tags of adjectives, nouns and adverbs in the initial position of the sentence (matrix position), followed by the word que. The attested combinations of form and meaning were tabled, giving rise to the groupings of the constructional network (sub-schemes). 175 types of BP-SIC were verified, counting on their different adjectival, adverbial, noun or (secondary) interjective matrices, with emphasis on adjectivals (117). Most of the matrices express non-modal evaluation, with some mirative uses and emphatic negations. Among the modal evaluation matrices, epistemic, deontic and evidential meanings are expressed.

Brazilian cities often suffer from floods, landslides and erosion caused by surface runoff. In order to mitigate these problems, sustainable urban drainage techniques incorporate infiltration, evapotranspiration and surface runoff retention strategies in order to mimic the pre-urbanization hydrological cycle. Therefore, the simulation of the operation of drainage techniques promotes a better understanding of the behavior of these structures, which can reflect in more efficient projects and better acceptance by the community. In this way, this work adapts, evaluates and applies the Characteristic Rain Events (CRE) methodology for selecting historical rainfall events that are statistically relevant for carrying out hydrological simulations of drainage systems. For this purpose, a computational tool capable of selecting rain events and calculating the hydrological balance of the most used sustainable drainage techniques in Brazil was developed using VBA language. Thus, through the simulation of some scenarios, using infiltration wells, infiltration trenches, rain barrels and vegetative swales it was observed that the results obtained with the proposed tool were similar to those obtained with the SWMM model and that the ECC through the application of PBIAS, NSE and RSR performance ratings.

Using the theoretical perspective of Feminist Institutionalism, in which institutions are structured in masculine values that creates barriers for women political representation, we aimed to study women representation in the Brazilian Federal Chamber from 2003 to 2019, analyzing political representation as an institutional process that responds to numerous incentives. We ask if the women’s presence in this institution implicates the descriptive representation and if the electoral victory of populist governments impacts the legislative production on gender issues. Our argument articulates that women’s representation is not linear, so their presence in the political arena does not necessarily translate into substantive politics and, in circumstances of right-wing populist leaders and values rises, gender agendas may be captured. Throughout the thesis we built a theoretical overview and used a mixed methodology to investigate the process of women representation in Brazil and the impact of populist governments on gender issues agenda, using comparative research between Brazil and the United States of America. We indicate that women representation in Brazil finds it difficult to be carried out at the hands of elected deputies because of institutional obstacles, given the low number of women in this arena and the structures that prevent and constrain the effectiveness of their actions. On the other hand, right-wing populist governments had a positive impact on the number of women elected, but not necessarily on the production of gender issues agenda by parliament, depending on the institutional arrangement, since in Brazil there was a negative impact and in the United States a positive impact.

Production planning and scheduling of machined-to-order parts in a job shop involves lot sizing and scheduling decisions. In this environment, there are several machines capable to execute various operations. Several ordered operations are required to transform raw material into each product and there is a possibility to produce a large number of products, which implies on machine setup and, consequently, reducing the available operational time. This study attempts to develop a model to assist in making decisions like lot sizing, allocation of operations in each machine for each lot and operations sequencing in each machine in an integrated approach in a flexible job shop environment that makes to order. The main contributions are the development and validation of mathematical model that represents the problem. Besides that, the review of production planning and scheduling models in job shop environment and the description of the problem in the case of machinery and equipment industry. Three formulations that integrate the decisions are analyzed and the one that achieves the optimal solution in the shortest time using CPLEX algorithm was chosen. Results indicate that the chosen model presents a feasible production plan and can be further applied in the machining sector. In a dynamic production environment, it might be necessary to update the production planning frequently, therefore a relax-and-fix algorithm is used to find an initial solution, which is further improved by a fix-and-optimize algorithm.

The use of pressurized carbon monoxide (CO) gas cylinders can lead to serious risks during their handling. Hence, the demand for safer carbonylation methods has been gradually increasing with the use of different techniques or CO-realeasing molecules. In the first chapter, we report a simple and direct palladium-catalyzed aminocarbonylation of 5-iodo-1,2,3-triazoles backbone for the incorporation of an amide functional group by employing an alternative source of carbon monoxide generated ex situ by dehydration of formic acid in sulfuric acid (Morgan’s reaction). The reaction was performed in a two-chamber system (COware) providing the synthesis of 26 compounds with yields up to 98% by using different primary amines and 5-iodo-1,2,3-triazoles. The methodology developed exhibited a series of advantages, such as simplicity, short reaction time, high yields, the use of dimethyl carbonate as a sustainable solvent, and the use of efficient alternative source of carbon monoxide, avoiding pressurized cylinder. The chapter 2 is focused on the development of a new catalytic protocol for the synthesis of seleno- and thioesters from a palladium-catalyzed carbonylative coupling reaction between aryl iodides and nucleophilic selenium and sulfur sources, which were obtained by in situ reductive cleavage of diorganoyl dichalcogenides with the assistance of zinc metal. This approach exhibited good functional group tolerance, allowing the synthesis of 30 compounds with yields up to 97%. Interestingly, aryl iodides carrying electron-withdrawing groups showed slower reactivity than those with electron-donating counterparts, affording the products with lower yields. For these cases, it was necessary to increase the amount of carbon monoxide to improve the reaction yield. The important features of this methodology include mild reaction conditions, the use of efficient alternative source of carbon monoxide, avoiding pressurized cylinder, and avoids the use of selenols and thiols, which are difficult-to-handle, easily oxidized, and have the unpleasant odor.

Production systems were transformed by the advances of the Industrial Revolutions. In order to keep up with technological progress and achieve desired productivity levels, maintenance management has become a key factor for organizations. Since every production system is prone to failures in its equipment, directly impacting the reduction of manufacturing capacity, it is necessary to properly use maintenance policies to keep a system in good operating condition. In this sense, it is understood that the greater the availability of equipment, the greater the productivity of the system. Thus, the present work aims to incorporate risk mitigation applied together with the modeling and simulation of discrete events as tools to support decision-making for maintenance policies that lead to increased availability and manufacturing productivity. For this, an industrial system prone to machine failures and belongs to the public administration was analyzed. In the case studied, the proposed scenarios considered that the inclusion of preventive maintenance policies with a bimonthly or quarterly frequency projects both an increase in the Mean Time Between Failures of corrective maintenance and a reduction of the Mean Time to Repair of preventive maintenance due to the anticipation of administrative procedures previously planned. The workstations submitted to such proposals were Workstation A, Workstation B and Workstation E, defined according to the risk matrix resulting from the relationship between the Annual Frequency of Failures and the Impact of Machine Unavailability. In the case of productivity, there was a gain of 10.4% in parts of the simulated products and a gain of 6.2% in subsets. In the case of availability, there was a gain of 50% in availability in Workstation A, 62% in availability in Workstation B and 41% in availability in Workstation E. Therefore, this research fills a gap in the literature by applying the modeling and simulation of discrete events in a risk analysis approach associated with maintenance management. In this way, it was possible to develop a ranking of workstations priorities and types of failure to be included in preventive maintenance policy proposals, resulting in availability and productivity gains for the studied production system.
