Prevalência da disfunção temporomandibular em estudantes de odontologia por meio de diferentes índices

The epidemiology of temporomandibular disorders varies widely in the literature. The aim of this study was to determine the prevalence of TMD in dental students of the Federal University of Rio Grande do Norte assessed by different indexes. The sample consisted of 101 individuals selected by a randomized process, whose general outline was systematic sampling. For evaluation of the signs and symptoms of TMD, an anamnestic index, Fonseca s protocol, and two clinical indexes, the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), or standard index, and the Helkimo s Clinical Dysfunction Index were applied. Data were analyzed using the chi-square test and kappa, besides verifying the sensitivity and specificity (5% significance). The diagnosis of TMD by different indexes showed a variation in the prevalence between 72.3% (Helkimo s Clinical index), 64.4% (Fonseca s anamnestic index) and 35.6% (RDC/TMD). There was no statistical difference between the sexes for the RDC/TMD, although this difference was found for Fonseca s and Helkimo s indexes (p<0.05). The most frequent type of TMD were joint disorders (Groups II and III), and the subtypes disc displacement with reduction (17.8%) and arthralgia (15.8%). Most individuals showed a mild TMD (45.5%) for both indexes, Fonseca and Helkimo. When comparing the types of diagnoses, RDC/TMD with Fonseca and Helkimo, low agreement was found (k=0.17 and k= 0.35, respectively). A moderate correlation between the severity of TMD was obtained (kw= 0.53) for Fonseca s protocol and Helkimo s index. High sensitivity and low specificity were seen for both diagnoses compared to standard, resulting in excessive false positives. Within the limitations of the study, it was concluded that the prevalence of TMD can vary widely, depending on the index used for its diagnosis

Práticas educativas e integralidade na saúde da família: um estudo etnográfico

Primary Health Care, especially in the family health strategy, it is expected that the joint assistance and actions of health promotion. The Ministry of health (BRAZIL, 2007) defines health education as an eyeshadow strategy of prevention and health promotion, based on reflective practices, which allow the user to their condition of historical, social and political subject, under the vision of an expanded clinic on the part of health professionals. In this sense, there are guidelines for it professionals to develop educational activities and that they can interfere in the health/disease process of the population, with a view to the development of autonomy of the subject. This research had as objective to understand in the light of the integrality of the care, as is the production of health education practices, within the framework of the family health strategy from ethnographic study in a family health unit (USF). The location of the research was the unit of USF Felipe Camarão II in West Health District, in the city of Natal, RN, Brazil, selected from preliminary mapping of educational practices deployed in units of health of the family of this municipality, based on criteria such as time-to-deployment of USF and sustainability of existing actions. Immersion in the field consisted of participant observation with journaling, held during the period of August 2012 to January 2013, in which she accompanied team work processes in clinical-welfare actions on the USF, in households and in educational activities of group character. The results presented in ethnographic description were analyzed based on the axes proposed by Ayres (2009) for identification of integrality in health practices:the axis of the needs; the axis of the purposes; the joint axis; and the axis of the interactionsThe evidence described from observation point the presence of each axle up health education practices developed by the teams, even incipient form, namely: articulation and appreciation of knowledge and practices of popular culture with local initiatives (Pastoril do Peixe Boi Encantado, Auto de Natal e Grupo Terapia e Arte); Clinical integration with health promotion actions and coordination of multidisciplinary knowledge, with professional-user link (course for pregnant women). However, a few challenges were identified to be faced in order to move forward in these practices in integral care: the need to break with the fragmentation of actions; strengthening teamwork; need for greater sustainability policy of collective actions; intersectoral work aimed at a better role of the State in the face of the health-disease process, adding to the action of individuals.The analysis produced from observation of the processes experienced indicates the need for a better recognition of local managers that actions similar to those that occur in the USF Felipe Camarão II enable advances in completeness as allows inclusion of actors involved in the processes of health work, and stimulate participation and shared responsibility in the fight for health-disease situations

PET-saúde na percepção de estudantes: contribuições para a formação na área de saúde

This dissertation aimed to analyze the perception of students about (EPW Health) Education Program at Work for Health Training in the area of Health. It discusses the proposed theme from the perception of students graduating from the EPW- Health courses participants (dentistry, medicine, physiotherapy, nursing, nutrition, physical education) who have developed their school activities in family health units in the city of João Pessoa between 2009/2011.The program aims policies curricular changes as a potential route of contributions to training in healthcare. Attention is drawn to the new possibilities of working health training contextualized, ethically grounded, socially endorsed. It is pointed out in this process the need to adapt to the demands of professional profiles of SUS (Sistema Único de Saúde). This is an exploratory, descriptive study within a qualitative approach, conducted in the city of João Pessoa in the context of health care courses at the Federal University of Paraiba. The empirical material of this study was treated by the use of technical analysis "Categorical Content Theme" by Bardin. The results indicate prospects for promoting new practices and curricular changes, which highlights the EPW- Health, which has been presenting important experiences in teaching -community -service- with the inclusion of students in the municipal health network. We conclude that the path from collection to data analysis, corroborated with the literature to reaffirm the importance and urgency of change in educational processes with a view to greater proximity to the health needs and the SUS. The EPW- Health project is incipient and requires further investigation in terms of effective interdisciplinary and multidisciplinary character of its proposal

A inserção das mulheres na Câmara Municipal de Natal (1988 - 2004)

This work has as objective to reflect about the insertion of the women in the City Council of Natal in the period from 1988 to 2004. We focused our discussion in the context of the politics of quota that has with objective to decrease the frame of inequalities existent between women and men in the politics, besides of to analyze which the determinants responsible for the women's sub-representation. The research still consists of an analysis of the councilor s women profile and how they were seen in that space of power. We analyzed our study object in a gender vision, since this is related intrinsically the social relationships and the relationships of power. The women, for a long time, they were excluded of the participation in the public life, being just seen as mere expectants. This research is informed mainly by studies which discuss the Gender (Scott, 1990), (Perrot, 1988), (Badinter, 1995), (Bruschini, 2002). We also analyzed the power, politics in the vision of Marx (1996), Foucault (1982) and (Arendt, 2001). We tried to analyze the women's presence in the spaces public and private, showing your conflicts and contradictions faced in the society, focalizing the political character of the women's inclusion in the spaces in that are inserted. The instrument of collection of data was the semi-structured questionnaire, descriptive and analytical - critical. The analyses of the interviews show to the sub-representation of women over the years as a determining factor for these women continue in the invisibility. The women were interviewed councillora ex- bounded from 1988 to 2004. The conclusion the one that we arrived is that this sub-representation has as decisive the patriarchal system that prevailed for a long time in our society and still dominates and affects women in all areas of your life. This becomes more serious in the capitalist society in which prevail the interests of those that it stops the produced wealth

Extensão universitária: concepções e ações na UFRN sob a temática direitos humanos e justiça no período 2008 a 2010

This paper concerns a study on the University Extension, by reference to the research extension activities under the theme human rights and justice, developed in the period 2008 to 2010 in UFRN. To do so, it tried to learn the concepts of extension in Brazil from the 1970s until the 2000s in contemporary times. This study considered the neoliberal social context of the University, dominated by educational policies focusing on the hegemony of liberal ideas about society, reflecting the great advances of capital on the organization of workers in the last decades and intensified in the 1990s. This research was guided by two great motivations: the opportunity to apprehend a way to enforce the commitment of public institutions of higher education to the disadvantaged sections of society and what role the university extension space plays as a socially committed public university. The general aim of this study is to identify inside the university extension education what does it mean for practitioners and extension activities and what results it produces to society and to the academic training of future professional citizens in the current neoliberal context. The research has been developed from an analytical and critical approach based on quantitative and qualitative data, using observation techniques and semi-structured interviews. We sought to investigate and understand the social reality, the main object of this work, with an interest in identifying the need for a new teaching/learning process and for a new university practice, in order to effectively improve an advanced academic formation. For this, some interviews have been conducted with teachers, students and the external community involved in extension actions in the period defined by the work, i.e., from 2008 to 2010. In this stage, it was observed that the academic work of university extension is essential to civic education. It was recognized too as a privileged space where university fulfills its social commitment towards society, as long as it joins scientific and popular knowledge having in view a new science and a new social order

Trabalho e saúde na sociedade capitalista: uma relação inversamente proporciona

It is a dissertation which has the Area of Concentration: Social Services, Vocational Training, Labour and Social Protection. Research Line: Social Services, Labor, Social Protection and Citizenship. Brings an approach to health and worker safety, approached on the organization of work in their processes of worker exploitation, analyzed from the critical perspective and all. Its central objective of uncovering how the organization of work affects the health of their workers, considering the working process in the capitalist mode of production, the health-disease relationship. Displays the worker, as determined by the work process, emphasizing, along the lines of capitalism, the consequences for the physical well-being, mental and social workers. To this end, we make a documentary and bibliographic research, whose point of analysis is based on the perspective of the centrality of work, recovering their sense of ontological Marx, through which the transformations are discussed in the working world, listed based on context productive restructuring of capital, which occurs along the imperialist stage of capitalist mode of production. It is problematized, though, worker health, analyzed from the wider definition of health as a field of public health, considering the work process in health-disease relationship. Finally, the research developed raised between 2006 and 2010, the Graduate Programs UFRN that address the range of issues studied in this dissertation. The scientific outputs are problematized as a way to reveal the theoretical trends (critical or conservative) which facilitate the thematic area

Violência e luta por direitos no capitalismo contemporâneo: crítica à configuração do atendimento às mulheres no Rio Grande do Norte

This research analyzes the Rio Grande do Norte care services to women who face violence in the context of contemporary capitalism. To do so, we situate the patriarchy in the set of current social relations and its relationship with the corporate determinations in everyday life. The new functions of the Patriarchy in the capital sociability permeates the lives of individuals and particularizes the relationships of violence which affects women, requiring, in the immediate level, policy-making to face them. The research found an arsenal of contradictory possibilities and limitations in dealing with violence. In this process, forms of struggle and resistance predominate, which appear as possibilities and limits were identified relate to the socio-historical context of regression of the rights, historical moment in which increase the objective difficulties in everyday life to ensure the legal achievements. It is worth to emphasize the achievements and contradictions that characterize the struggle process for rights, linking services to women to the social policies and to the limits they face in opposition to the aims of the State to meet the mandatory requirements of capital, reducing its role as the main guarantor of policies and rights. In this sense, the trajectory of the achievements that have referred to the proclamation of a specific law to deal with combat violence against women, the Maria da Penha Law - 11.340/06, which provides an integrated set of measures that, if implemented, would allow the women protection from relations of violence they experience. We identified in Rio Grande do Norte precarious services that are essential to achieve the Maria da Penha Law. This situation requires a feminist organization to claim the rights that enable women to see themselves as people with rights in the process of collective struggle. This is the historical need for continuity of struggles that accumulate policies for the existence of a new model of social relations of gender. One of the possibilities that are presented in the current context is the impact on the public budget in order to ensure compliance with the budget for public policies for women - woman budget. In this perspective, feminist segments in national and state level have been organized to understand the functioning and monitoring of social policies. This is a condition and prerequisite for ensuring policies to ensure basic rights and the violence combat , which still requires an integrated set of services. The survey results allow us to consider that the struggle for rights is necessary at this historical moment, however it is not sufficient in human emancipation, which requires new forms of social relations that determine substantive equality between men and women. Thus, the feminist movement faces the challenge to organize and strengthen itself in daily life, in order to execute a project that changes the meaning of women's rights, articulated to a corporate project which wants other command in the set of social relations . This study emphasizes the need for a more and more organic connection between feminism and social struggles, to ensure the inclusion of women in anti-capitalist struggle

Turismo, capital social e produção do espaço: uma leitura a partir do município de Natal/RN no período de 1980 a 2012

Nowadays, there is a tourism phase in the city of Natal/RN called internationalization of tourism , which shows a tourism model with a planning and an administration, based on the needs of the visitors. Such process shows that the production as well as the reproduction of the city spaces with the goal of favor tourism excludes of its composition the effective participation of local subjects. Thus, the research is a result of the perception of tourism as an activity with a meaningful power of transformation of the social and natural space taking into account the low participation of the residents in the decisions of the tourism activities in the city of Natal/RN. Despite that reality, it is possible to note Natal that civil society, starts to mobilize its citizens trying to develop collective actions to low the negative impacts caused by the bad planning as wells not efficient tourism administration, trying to put in action the right of the local population to take part in the decisions of the city activities. Having this panorama as background, this paper aims at investigating in which way the mobilizing action of the social capital in Natal has contributed to change the spatial production which is part of the process of expansion of tourism in Natal/RN? The research presents a temporal picture which starts in the year of 1980, when occurs the first effective state intervention aiming to develop tourism in the capital, taking into account an analysis of 2012. Concerning the spatial picture, the research investigates the beaches of Natal which concentrates criteria and actions such as: visitation, tourism appeal and focus of investments, highlighting the following beaches: Ponta Negra, Areia Preta, Praia dos Artistas, Praia do Meio, Praia do Forte and Redinha. This study is of a descriptive and exploratory nature concerning its goals. With respect to the treatment of its object it is a qualitative research. The data was collected through structural interviews, with open questions. Regarding the methodological choices, it was used the content analysis proposed as well as the collective discursive subject methodology. The results show that there´s not yet in Natal a meaningful social capital related to tourism, capable to change the spatial production related to the activity. It should be stressed that Natal social capital presents difficulties concerning the incentive to trust, spontaneous cooperation and the civic participation, which are the foundation for the development of an effective social capital, which makes it harder for a more expressive articulation in the reality in Natal/RN. It should be stressed, as an answer to the research questions, that tourism in Natal/RN is represented by social and spatial segregation. In other words it emphasizes mainly the action of hegemonic agents (State and market), leaving little room for the participation of society. It can be noticed that the actions related to tourism in Natal keeps the popular participation out of the way. Thus, it can be said that the social capital in Natal/RN does not yet contribute to a more fair spatial production related to the expansion of the tourism as well as the well being of the population of Natal/RN. In conclusion, it should be taken into account that this participation do exists but not in a meaningful way. In other words, it´s not enough yet to cause meaningful changes in the actions which tourism needs nowadays in Natal/RN

Gestão por Competências em Organizações Públicas: O Processo de Transformação Organizacional e seus Impactos Junto aos Servidores na Secretaria Estadual de Administração e Recursos Humanos (SEARH/RN)

The state has changed over time in order to meet a society with increasingly stringent demands. Techniques of private means begin to be employed in an attempt to overcome the dysfunctions entrenched bureaucracy, making the machine faster. By federal law by the People Management Skills was established as a reference for the administration of Human Resources of the public sector in an attempt to develop professionally servers, based mainly on the three pillars of the model: the knowledge, skills and attitudes. This thesis aims at understanding, in the view of employees, the perceived impacts on the organizational changes occurring in the Department of Administration and Human Resources of the State of Rio Grande do Norte in order to implement a People Management Skills-based. It is a simple case study, characterized by the research during a certain period of time, collecting data in a real environment of an organization, in this case SEARH/RN. The procedures used in collecting data were the literature review, documental research and field research. We used a qualitative approach with exploratory and descriptive approach. Every reform was implemented in the institution and reported from there analyzed the impacts observed by the servers. As a result we observed a considerable advance in institutional activities, mainly relating to physical structure / organizational and human resource policies, with minor advances on labor policies, in much the result of the guiding focus of the reform on SEARH/RN. The impacts in total were more positive than negative and direct paths to improvement in public organizations. Making a general analysis of the modernization program implemented in SEARH/RN, we can conclude that there was a distinct change in all dimensions studied, mostly pointing out positive aspects, and contrary to the opinion of some authors, who claim to be very difficult to implement reforms in public organizations, since they are highly institutionalized environments. What was found was a big organization, with gaps and weaknesses, but with a much larger number of hits and recognition from institutional actors

A moralidade e a vida pregressa do candidato como condição autônoma de elegibilidade

The objective of this work was about fixing the free will paradigm as negative evaluation of political rights which presents a new classification dde such rights, producing species: a) conditions of eligibility autonomous (free will), b) eligibility requirements heteronomous (will third party) and c) ineligibility (court decisions / administrative). This morality and life history as a condition of eligibility unattended, making a hermeneutic analysis of art. 14, § 9 of the Constitution, considering the justification of the views of the voting Minister Carlos Ayres Brito Appeal in Ordinary No 1069/2006 of the Supreme Electoral Tribunal (where Eurico Miranda). Are fixed concepts of morality and life history from the perspective of the moral act freely and consciously. Has resulted in the identification of the moral virtues of honesty and integrity, which are voluntary acts as a reference to morality and integrity respectively. Justifies the morality and life history as a condition of eligibility unattended. who depend exclusively on the willingness of the candidate. It is noteworthy that the conditions for eligibility as a factual finding does not violate the law and does not allow punitive sanctions or setting a deadline in case of refusal to register the application. Attributed to political parties to take responsibility in their statutes moral criteria for the nomination convention in pre candidates, giving an ethical dimension. Analyzes the law under the Clean Record of morality and life history of the candidate and the possible impact on the electoral context

Ação de impugnação de mandato eletivo: análise constitucional e novas perspectivas

This study is developed in setting in which the Federal Constitution of 1988 completed 22 years of validity, as well as in general elections (national and state) in country. From this perspective, there are multiple reflections, especially on the constitutional mechanisms of popular sovereignty consolidation, the integrity and legitimacy of elections and democracy itself. It has appeared timely, therefore, to examine the development of ensured instrument of these precepts. Thus, it is approached as an object of research to Action of Impugnation to the Elective Mandate- AIEM, under Art.14, § 10 and § 11 of the Constitution of 1988, considering its constitutional and electoral reasons. It is then aimed to review the second AIEM conceptions of scale, systematic interpretation, preservation of constitutional rights and its effectiveness. Specifically, it is analyzed the Action as to the forms of power that relate to this. then it is examined the democracy principal aspects related to the issue. Without being followed, it is the democratic situation in which it is operated. They are also examined the political rights, especially regarding restraint applied to ineligibility and the possibility of integrating the effects of an impugnatory origin. Following, it has been discussed the formation of an early panorama, consisting of constitutional principles applied to electoral constituencies and eminently procedural principles and, according to which subsidizes the operations of such Action. After that, addressing the Election Law, including its concept, its sources, the Electoral Court and its peculiarities and functions. It is also considered the elective office as to its definition, characteristics and ways of accessing and extinguishing it. Afterwards, the Action of Impugnation is studied from its historical evolution of laws, legal, concept and goals. Expanding on the theme, it s highlighted about their chances of traditional appropriateness (economic power abuse, corruption and fraud) and modern (abuse of economic power intertwined with political) business, including the suggestion of suitability in case of abuse of unique political power. It was also identified the injurious potential demand affecting these illicit to enable the Action. Subsequently, other relevant aspects were explored, such as the legitimacy ad causam, competence, secrecy, procedure, recklessness, bad faith, the purpose of the merits and manageable resources. In the end, it is demonstrated an evolution of AIEM, however, still insufficient to reach full intentions that rise it. It is proposed therefore to re-read the action from news perspectives, based on constitutional and electoral precepts, as well as wider interpretation of the appropriateness of their assumptions of suitability and effects, according to a systematic interpretation, all aimed at the preservation of constitutional rights and their own effectiveness

Reavaliação de critérios estruturais na hidrogeologia de terrenos cristalinos, com ênfase na neotectônica e sensoriamento remoto

Hydrogeological prospecting in Northeast Brazil and in other crystalline terrains has been developed on the basis of structural and regional geology concepts that date back to the 50-60 decades and, as such, demand a natural re-evaluation and update. In this kind of terrain, the percolation and accumulation of ground water are controlled by fractures and other types of discontinuities, such as foliations and geological contacts that, through weathering, impart porosity and permeability to the rocks, allowing water flow and storage. Several factors should be considered in the process of locating water wells, as discussed in the literature. Among these, the kind of structures, fracture geometry (including aperture and connectivity) and their geological and chronological context. It is important to correlate fracture systems with the regional neotectonic framework. Fractures at low angle (sub parallel) with the principal stress axis (s1) are those which tend to open (actually they work as tension joints) and, in principle, would present major hydric potential; in the opposite side, fractures at high angle to s1 would behave as closed by a compressional component. Fractures diagonal to the compression and tension axes correspond to shear fractures and, due to their connectivity with second fractures, are also important in terms of hydric potential. Uplift followed by terrain denudation leads to decompression and a general tendency to open (aided by weathering processes) fractures and other rock discontinuities, at different orientations. Low angle fractures, formed in this context, are equally important to increase connectivity, collection of water and recharge of the aquifer systems. In a general way, an opening component (neotectonic or by terrain decompression) and several models to increase fracture connectivity correlate with a greater hydric potential of these structures. Together with parallel research, this thesis addresses models of ground water occurrence in crystalline terrains, either improving well established concepts like the (Riacho-Fenda model), but also stressing other possibilities, like the role of alluvium and paleo-regoliths (the Calha Elúvio-Aluvionar model) and of strongly altered, permo-porous zones placed at variable depths below the present surface, flanking several types of discontinuities, especially interconnected fracture arrays (the Bolsões de Intemperismo model). Different methodological approaches are also discussed in order to improve success rates in the location of water wells in crystalline terrains. In this methodological review, a number of case studies were selected in the eastern domain of the State of Rio Grande do Norte, involving the localities of Santa Cruz, Santo Antônio, Serrinha, Nova Cruz, Montanhas, Lagoa de Pedras and Lagoa Salgada. Besides the neotectonic analysis of brittle structures, this Thesis addresses the validation of remote sensing as a tool for ground water prospecting. Several techniques were tested in order to detect and select areas with higher potential for ground water accumulation, using Landsat 5-TM and RADARSAT images, besides conventional aerial photos. A number of filters were tested to emphasize lineaments in the images, improving their discrimination, to identify areas with higher overburden humidity, which could reflect subsurface water accumulation, as well as alluvium and other sedimentary covers that might act as recharge zones. The work started with a regional analysis with the orbital images, followed by analysis of aerial photos, up to a detailed structural study of rock exposures in the terrain. This last step involved the analysis of outcrops surrounding wells (in a ray of approximately 10 to 100 m) with distinct productivities, including dry examples. At the level required for detail, it was not possible to accomplish a statistical approach using the available well data catalogs, which lack the desired specific information. The methodology worked out in this Thesis must undergo a testing phase through location of new water wells. An increase in the success rates as desired will led to a further consolidation step with wider divulgation of the methodology to private companies and governmental agencies involved in ground water prospecting in crystalline terrains

A mineração artesanal e de pequena escala em pegmatitos e cerâmica no município de Parelhas, região do Seridó/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Seridó, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

Aplicação de resíduo industrial para isolamento térmico: uma proposta para utilização do poliuretano de mamona com agregado de resíduo plástico termofixo

A aplicação de isolantes térmicos em sistemas construtivos promove vantagens com vistas ao conforto térmico de ambientes. E com isso, o aumento da produtividade em locais de trabalho, a sensação de bem-estar e a diminuição dos custos com climatização. A demanda por conforto ambiental, no âmbito da isolação térmica, somada ao advento de novas leis que regulam os requisitos mínimos de conforto, as exigências dos consumidores pela adoção de métodos de produção mais “limpos”, a fiscalização quanto à destinação de resíduos industriais, além da inserção de produtos no mercado com apelos ambientais, incentivaram o desenvolvimento da presente pesquisa. O presente trabalho trata da aplicação do poliuretano, visando comparar o desempenho térmico do derivado de origem vegetal (óleo de mamona) com adição de resíduo plástico termofixo em diferentes proporções (5%, 10%, 15% e 20%), com o poliuretano petrolífero, a lã de vidro e a lã de rocha através da análise de suas propriedades térmicas (condutividade térmica – k, difusividade térmica – e capacidade calorífica – Cp). . Após a realização dos ensaios, os compósitos estudados foram moídos e reutilizados como carga para novos compósitos. Com base nos resultados dos ensaios de propriedades térmicas, constatou-se que o material desenvolvido conduz menos calor que o poliuretano de petróleo, a lã de vidro e a lã de rocha, além de oferecer alta inércia térmica, bom desempenho térmico e baixo custo. Assim como foi comprovada a possibilidade de fabricação de novos compósitos para fins de isolamento, reutilizando os compósitos testados
