Síntese e caracterização de catalisadores de LaNiO3 não suportados e suportados em Al2O3 e ZrO2 para a reforma a vapor do metano

Ionic oxides with ABO3 structure, where A represents a rare earth element or an alkaline metal and B is a transition metal from group VIII of the periodic table are potential catalysts for oxidation and good candidates for steam reforming reaction. Different methods have been considered for the synthesis of the oxide materials with perovskite structure to produce a high homogeneous material with low amount of impurities and low calcination temperatures. In the current work, oxides with the LaNiO3 formula had been synthesized using the method of the polymeric precursors. The thermal treatment of the materials took place at 300 ºC for 2h. The material supported in alumina and/or zirconia was calcined at 800 ºC temperature for 4h. The samples had been characterized by the following techniques: thermogravimetry; infrared spectroscopy; X-ray diffraction; specific surface area; distribution of particle size; scanning electron microscopy and thermo-programmed reduction. The steam reforming reaction was carried out in a pilot plant using reducing atmosphere in the reactor with a mixture of 10% H2-Argon, a mass about 5g of catalyst, flowing at 50 mL.min-1. The temperature range used was 50 - 1000 oC with a heating rate of 10 oC.min-1. A thermal conductivity detector was used to analyze the gas after the water trapping, in order to permit to quantify the consumption of hydrogen for the lanthanum nickelates (LaNiO3). The results showed that lanthanum nickelate were more efficient when supported in alumina than when supported in zirconia. It was observed that the methane conversion was approximately 100% and the selectivity to hydrogen was about 70%. In all cases were verified low selectivity to CO and CO2

Reforma a seco de metano com catalisadores Ni/MCM-41 sintetizados a partir de fontes alternativas de sílica

The production of synthesis gas has received renewed attention due to demand for renewable energies to reduce the emissions of gases responsible for enhanced greenhouse effect. This work was carried out in order to synthesize, characterize and evaluate the implementation of nickel catalysts on MCM-41 in dry reforming reactions of methane. The mesoporous molecular sieves were synthesized using as silica sources the tetraethyl orthosilicate (TEOS) and residual glass powder (PV). The sieves were impregnated with 10% nickel to obtain the metallic catalysts (Ni/MCM-41). These materials were calcined and characterized by Thermogravimetric Analysis (TG), Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), Temperature-Programmed Reduction (TPR) and N2 Adsorption/Desorption isotherms (BET/BJH). The catalytic properties of the samples were evaluated in methane dry reforming with CO2 in order to produce synthesis gas to be used in the petrochemical industry. The materials characterized showed hexagonal structure characteristic of mesoporous material MCM-41 type, being maintained after impregnation with nickel. The samples presented variations in the specific surface area, average volume and diameter of pores based on the type of interaction between the nickel and the mesoporous support. The result of the the catalytic tests showed conversions about 91% CO2, 86% CH4, yelds about 85% CO and 81% H2 to Ni/MCM-41_TEOS_C, and conversions about 87% CO2, 82% CH4, yelds about 70% CO and 59% H2 to Ni/MCM-41_PV_C. The similar performance confirms that the TEOS can be replaced by a less noble materials

A encruzilhada da vida política em assentamentos de reforma agrária no Rio Grande do Norte

The rural settlements represent a mark in the expensive historical process of fight by the land in Brazil. At first offer basic terms of survival, through the access the land and of the fundamental supports for exploration. At the same time, have stimulated organization forms politicizes of the families who manage to work with the new challenges of the everyday. The moment that follows the land conquest, and therefore, the settlements construction while life and work project, it is crossed for objective and subjective demands, with highlight for options of agricultural production and strategies of collective action. Originally formed as representation instance legitimates of the families - front to the government and social actors - the settlers associations are private spaces for political sociability, that guided by principles participative, can lead the settlers the new conquests through indeed democratic experiences. The goal of this work is to comprehend the participation forms in the scope of these associations and the way as that translates in life best terms for the group, from the settlements experiences located in the Territories of the Citizenship Mato Grande and Açu-Mossoró, in Rio Grande do Norte's State. The theoretical conceptions that guide this analysis are concentrate on discussions about democracy and participation (Patermam, Putnam, Bodernave) and in the reflections about the rural world (Medeiros, Martins, Woodman e Woodman and Bergamansco). About methodological, different point of view strategies were developed: The direct observation, the application in locate of questionnaires to the families settlers and interviews semi-structured with the internal leaderships. With that could verify that the participation forms in the associations operate in two heartfelt: Of a side, they promote assimilation opportunities of democratic abilities accompanied of notions of social rights and redefinition of political standards; Of another, it offers indeed the possibility of the settlers lead, with relative autonomy, the political organization and her changes in direction to a way of life that wish to have in the settling

"Reforma urbana já"; "arroz, feijão, saúde e habitação" :A luta por moradia na grande João Pessoa

Our object of study in this work concerns to the movement of fight for the housing in the Great João Pessoa, Paraíba, Brazil, and looks for to investigate the conditions and context of the occupations of building, public or private, for devoid populations that do not have where to live. Front to the absence of politics effective directed to the habitation or the cities, in a picture of unemployment and impoverishment of the population, the result of the habitation point of view, is the absolute lack of popular housings, the degradation of the cities and the growth of the number of homeless and also of its occupations. The urban occupations today represent a reply of these devoid populations that from an involvement with parties or Not Governmental Organizations, and social movements leave for the class action known by the occupation of abandoning public or private buildings. These occupations, even so initially if assume as pressure instrument or of visibility for attainment of housings, for the delay in obtaining the attention of the public agencies and a solution for the problem, becomes definitive or is drawn out per many years. E this if gives although the deficiencies, of the accumulation or families neither in an adequate, always precarious space nor in sanitary installations, that the necessary privacy does not allow. The study it consisted of an empirical research, through the participant comment and open and half-open interviews, and counted on the audiovisual register of two occupations, one in the downtown of João Pessoa City (old building of the INSS, in the Ponto dos Cem Réis) and other (Community of the Cajueiro), next to the Beach "Praia do Jacaré", in the city of Cabedelo.The choice of the Visual Anthropology as research instrument is on to a concern in better translating other ways of life, therefore the accomplishment of the video in allows them to know with more precision the reality where the citizens of the research live. We also use as methodological resource in the research the deepened interview, in intention to better understand the description of the way of life of the studied families and the movements of fight for the housing, particularly the MDM - Movement of Right for the Housing, and the MNLM- Nacional Movement of Fight for the Housing

Reforma administrativa e gestão de políticas sociais em Mossoró: a falácia dos atores institucionais e sociais

The thesis entitled The administrative reform and social political management in Mossoró: the institutional and social staff's falacy. Comprehends a moment of apprehensiveness and analysis in the reestrcturing process of the city, whose process will show the formation of strategies and deployment of its relation with the social political affectiveness. It represents a single moment in the approach of such a kind of experience in the city. The analysis starts from the third mandate of the Mayor Rosalba Ciarlini Rosado, during the quadriennium 2001/2004, for being the time in which the public management got materialized, such as in the operational way of the social politics. For that, we delimitate this study in two distinct moments: the first one refers to the reform elaboration from the creation of the additional law nº 001/2000 GP/PMM: the second one refers to a practical reform from the social and institutional staff's speech. Within that scenary it was seen that the approaching, though partially, the State Reform and, consequently, the master plan of the state apparatus, which were made of theoretical matrices of such a project locally. However, that is a complex experience, that required the use of field and documental research for the proposed investigation and at the same time, prove the guiding hypothesis of it, what means a grouping of areas like: education, healthy, and social development in only one department City Citizenship Department that is able to materialize a new intitutional arrangement, according to the management principles in the public administration at the govern local level, configuring a reform and not just an institutional adequacy. In that context, it got necessary to apprehending the institutional and social actors' falacy as a way to prove or not the presented hypothesis. Among the first staff, we have the mayor's direct leaders and advisors' perception that express the politcal administrative aspects of the reform and, in the second, the perception of the political view of what has changed concerning the management of the social politics

Desenvolvimento e políticas públicas: uma avaliação do PRONAF nos assentamentos de reforma agrária do Rio Grande do Norte

The research DEVELOPMENT AND PUBLIC POLICY: AN EVALUATION OF PRONAF IN THE SETTLEMENTS AGRARIAN REFORM OF RIO GRANDE DO NORTE aimed to evaluate the effectiveness of the National Program for Strengthening Family enhancerelement od development in rural settlements od Rio Grande do Norte. The methodological approach consisted of the completion of desk research and literature on development issues, policies, and rural credit and field research through semi- structured interviews with managers and technicians who work with the program and conducting focus with farmers settles who accessed the PRONAF the period from 2000 to 2006. The survey results confirm the central hypothesis of this work, that acces to PRONAF A is not causing efetivations relevant in the lives of farm workers settlers in Rio Grande do Norte. In the setllements where efetivations these occur, they are short of what the program intends to carry out and rely on a set of conditionalities that are beyond the operational frameworks of the same. Such questions point to the need to revise the program in order to estabilish adjustments that in practice the approach of the proposed objectives. For this purpose it is necessary to invest in factor that contribute to the program has a positive effect not only to increase income, but to contribute to the autonomy of the resettled farmers, expanding its capabilities and increased the power of choise with respect to life who wish to take

Desenvolvimento como acesso às políticas públicas: a reforma do estado e a concretização dos direitos prestacionais

The state s evolution, after its liberal and the social stages, arrives at the post-social state, also regarded as regulatory state, which, in order to accomplish the state s aims, employs indirect interventions in the economy. The new model of administration adapts principles and concepts form the private sector such as the quest for efficience and tangible results, also striving for the decentralization of state s power to improve effectiveness before the new paradigm of handling of affairs of public interest. Present state derives its legitimacy from the efficiency principle, the legitimacy of the public administration cannot be limited to an analysis of legality, but the fulfillment of the ends envisaged by the public authority on its policies. These public policies have the objective of satisfying fundamental rights of the citizens. The access to public policies set by states as a way of enjoyment of the aforementioned rights constitute a legal and demandable path of development. The creation of public policies and the access to them must abide to the efficiency principle. This access must be taken unther the principles of legal and material equality, inasmuch as the liberty and real liberty. The access must also be observed as a matter of limited resources to grant, in reality, the access and enjoyment of these rights. The demandable nature of the access to public policies binds the public authority into broadening the range of these policies to every one who needs them. Thus, in this spectrum, the role of the Regulatory State, as the legal instruments for access of public policies as a legal path to development, is analyzed in the present work

Vida, experiência, conhecimento : a reforma do sujeito cognoscente em Tsunessaburo Makiguchi

Utilizing a great part of the works by Japanese educator Tsunesaburo Makiguchi and the register of fragments of his life, this thesis affirms that knowledge emerges from peoples` experience as they go about their daily lives. Facts, events, genetic inheritance, cultural patrimony, family history, the place where one was born and lived, and psychological predispositions nurture and form a vision of the world and of life in general. In Makiguchi s case, this multi-causal constellation led him to conceive the system of the value-creating pedagogy of good, gain and beauty; discussing the importance of cognition and evaluation in the experience of the human being. His life is exemplary in demonstrating that these aspects are inter-connected and, in a recursive movement between knowledge and self-knowledge, they can generate creative systems for understanding the world and introducing, essentially, the author into the epistemological problematic of complexity. The Makiguchian system and Edgar Morin s complexity approach suggest a pragmatic, paradigmatic reform of education and a thought reformation in the direction of the complex pedagogy, and that it creates a web that connects master-disciple, subject-object, human-world, local-global and singular-universal

A dimensão sociocultural da reforma psiquiátrica: articulando redes para a consolidação da estratégia de atenção psicossocial

This thesis aims to discuss on articulations that have been produced on the socio-cultural field in the Psychiatric Reform process and its pertinence to the streghtening of Psychosocial Care Strategy (EAPS) in Fortaleza/CE. Such interest has been justified by the need to promote not only the production of these networks, but also interfaces to enable strategies of support and sociability from the perspective of deinstitutionalization of madness. We were inspired by the cartography perspective of Deleuze e Guattari, and determined as objectives: 1) to discuss the complexity of Psychiatric Reform process and analyze the EAPS as a model for the current Mental Health policy in the country; 2) to map socio-cultural strategies connected to the CAPS network in the city, investigating experiences that already exist or may be constituted as everyday social support networks; 3) from that mapping to start, define and discuss some aspects that converge to the accomplishment for this new mental health paradigm, drawing a cartography of the issues and movements in progress. The mapping was carried out in 2009 and consisted of semi-structured interviews with the coordinators of the 14 existent CAPS and with some people connected to the Coordination of Mental Health. Besides, during the whole development of the study, we have taken part in public events that brought us clues on the connection between mental health and culture. From the survey produced, we defined three vectors for discussion (Art, Labour and Partnership with Social Movements) which have been highlighted as effective possibilities of intervention in the socio-cultural field of Psychiatric Reform in Fortaleza and reveal important paths on the fulfillment process of a new pattern of care. For each of these axes, we chose a field of empirical research (Projeto Arte e Saúde, COOPCAPS e MSMCBJ) in which we could better understand their strengths and difficulties, starting from open interviews with some of their actors and the production of a diary of sensations in 2010. We have seen that they are articulated with the proposal of EAPS, being part of the concerns to the National Mental Health Policy and also the municipal administration. However, we have noticed to be necessary to promote those dimensions further, focusing on its complexity at the macro and micro policies, with the purpose of leading the Psychiatric Reform process

O ambulatório de Saúde Mental no contexto da Reforma Psiquiátrica em Natal/RN

The years 1990 disclose the consolidation of the Brazilian Psychiatric Reform project, assumed as official politics by the Health Department, also stirring up discussions, lines of direction and new ways of care. Substitutive services to the psychiatric hospital as CAPS, conviviality centers, therapeutical residences and ambulatory clinics are implemented. This work analyzes the relations that the Specialized Ambulatory Clinic of Ribeira establishes to the services of Mental Health of the public system in the city of Natal/RN, as well as its adjustment to the proposal of the Psychiatric Reform. Through semi-structured interviews and observation, it was possible to gather data which allowed picturing a general characterization of the service: activities, technical group, joint with other institutions, daily routine organization. Such institution develops activities that surpass the traditional character of a clinic- in other words, the psychological/medical appointments - and it mainly greets the ones proceeding from CAPS and psychiatric hospitals. It offers group activities, psychiatric appointments, therapeutical workshops, sheltering and strolls, among others. The institution is composed by a multi-professional team of psychiatrists, psychologists, occupational therapists, nurse s aide and art-educator. The joint of this service with others that make part of the Mental Health Assistance network in Natal is incipient. Due to this fact, some actions and activities that could and should be developed together are just not. Although facing difficulties, the professionals of the Ambulatory Clinic of Ribeira are able to achieve good results and establish care in Mental Health that prioritize sheltering, listening and respect to the user s individuality. The Ambulatory Clinic of Ribeira is organized according to the paradigm of the Psychiatric Reform. Therefore, it offers an attention that stimulates the re-socialization of the users and the exercise of the citizenship and autonomy of those

O Serviço Ambulatorial Móvel de Urgência (SAMU) no contexto da reforma psiquiátrica: em análise a experiência de Aracaju/SE

This research investigated professional practices from Mobile Urgency Care Service (Serviço Ambulatorial Móvel de Urgência - SAMU) at psychiatric cases of the city of Aracaju/SE, Brazil and its possible articulations to psychosocial services network. The regulation no. 2048 of 11/05/2002 from Ministry Health establishes National Urgency Policy and designates that psychiatric cases are SAMU's responsibility. Then, it is necessary to propose an analyze of psychiatric urgency service under anti-asylums social movements standpoint, mainly because this service is responsive in assisting a person in crises. Fieldwork was developed in two phases. First one was made with SAMU workers and the information were produced by recorded semi-structured interviews. Results of this first phase indicate that urgency psychiatric conception from SAMU workers is based on aggressiveness concept; delays at psychiatric cases support and low training in mental health care which means several difficulties to emergency service. Although, we noticed that SAMU use asylum procedures at psychiatric cases like ropes and odder instruments to contain people. The second step of our research was to attend meetings to build a new psychiatric urgencies protocol for SAMU to define practices to auxiliaries, vehicular conductors and medical support regulation. Therefore, open interviews were accomplished with some participators and follows-up to psychiatric case on board of SAMU's cars. Afterwards we discussed how the urgency paradigm, that influence the protocol draw and as consequence distort what we believe is the essentially function of this device, that is to give care support to persons in crises and produce articulation to psychosocial services network

Em defesa da reforma psiquiátrica :por um amanhã que há de renascer sem pedir licença

Insanity was victim of several arbitrary acts perpetrated on behalf of the science. Psychiatric reform constitues an important movement which has attempted to rescue dignity and humanity in the treatment of mental disorder patients. Some countries have advanced in the implement of substutive models that work on the construction of a new social place for madness. The model of attention to mental health in Brazil has also suffered extensive modifications due to the wearing out of the psychiatric hospital model. In Santos, a town in the State of Sao Paulo, we have found a landmark in the development of an anti internment politics, through the creation of a dail care service, including psychosocial assistance. It is in this context that it has been founded in Natal, Rio Grande do Norte, the NAPS and CAPS ( Nucleus and Centres of Psychosocial Attention), municipal strategies that put into effect the law # 10.216/2001, which estabilishes the gradual extinction of psychiatric hospitals. This work has the purpose of carrying out a study about the historical process of psychiatric reform implantation in the State of Rio Grande do Norte, emphasizing the actors involved in process, their trajectory, achievements, improvements, and the movement s perspectives of achieving the ideal of reinstating mental disorder patients. In order to accomplish this purpose, it was necessary to understand the process occurred at the Municipal Secretary s Office for Health, since 1992, for it was the impelling experience towards the reflections about the psychiatric reform in the State of Rio Grande do Norte. The instruments used for this work were documentary analysis, through reports, legislation and handbooks, as well as the staments of people involved in this process. Through the statements analysis, we attempted to estabilish the social actors identity, their perception, emphasizing congruences and incongruences concerning the history of psychiatric reform in the State of Rio Grande do Norte. It is also analyzed the contribution of Psychology in this process, which has become a protagonist in the struggle for the rights of mental disorder patients

Nem tudo que reluz é ouro: oficinas terapêuticas no cenário da Reforma Psiquiátrica

The purpose of this study is to discuss the therapeutic workshops function, while questioning if they constitute a mechanism for change of the traditional asylum logic. The Psychiatric Reform was materialized with the financing and regulation of alternative services that substitute the psychiatric hospital. This change was promoted by the anti asylum debate and the deinstitutionalization besides psychosocial rehabilitation paradigms. Mental health care, therefore, acquired a new form and the Centers for Psychosocial Care (CAPS) are considered the main services of the health network presently under construction. They are services that offer a variety of therapeutics and amongst them is the workshop, considered essential for the advancement of the Reform ideas. The study was conducted in a CAPS II in Natal, RN. Systematic visits were made using the Institutional Analysis perspective, futhermore were made interviews with professionals who was related to workshops. In the end, data were then discussed according to Schizoanalysis. Results denot that workshops represents, in the same time, progress and regress of Psychiatric Reform. It was observed that workshops were oftentimes reduced to strategies for the occupation of time, and as a means for the transmission of social values considered correct. The relationship between professionals and the user of the service was hierarchical and both players was seeing the workshop as a task to be met. Although users expressed intreresting about wokshops, was reported that the work was boring. Besides, except for some cases, the therapeutic workshops wasn t helping clients to create other possibilites in theirs life and stops the job inside the mental care service

Carregadores de oxigênio a base de níquel suportado em materiais mesooros para aplicação na recirculação química com reforma (RQR)

Oxygen carriers are metal oxides which have the ability to oxidize and reduce easily by various cycles. Due to this property these materials are widely usedin Chemical-Looping Reforming processes to produce H2 and syngas. In this work supports based on MCM-41 and La-SiO2 were synthesized by hydrothermal method. After the synthesis step they were calcined at 550°C for 2 hours and characterized by TG, XRD, surface area using the BET method and FTIR spectroscopy. The deposition of active phase, in this case Nickel, took place in the proportions of 5, 10 and 20% by weight of metallic nickel, for use as oxygen carriers.The XRD showed that increasing in the content of Ni supported on MCM-41 resulted in a decrease in spatial structure and lattice parameter of the material. The adsorption and desorption curves of the MCM-41 samples exhibited variations with the increase of Ni deposited. Surface area, average pore diameter and wall density of silica showed significant changes , due to the increase of the active phase on the mesoporous material. By other hand, in the samples with La-SiO2 composition was not observed peaks characteristic of hexagonal structure, in the XRD diffractogram. The adsorption/desorption isotherms of nitrogen observed are type IV, characteristic of mesoporous materials. The catalytic test indicates that the supports have no influence in the process, but the nickel concentration is very important, because the results for minor concentration of nickel are not good. The ratio H2/O2 was close to 2, for all 15 cycles involving the test storage capacity of O2, indicating that the materials are effective for oxygen transport
