Nitrogênio em cobertura e qualidade fisiológica e sanitária de sementes de painço (Panicum miliaceum L.)

O nitrogênio pode influenciar a qualidade das sementes de várias culturas e os seus efeitos variam com as condições ambientais e o estádio de desenvolvimento da planta em que a aplicação é realizada. Porém, pouco se sabe sobre a influência da adubação nitrogenada na qualidade de sementes da cultura do painço (Panicum miliaceum L.). O objetivo neste trabalho foi avaliar o efeito de doses e épocas de aplicação de nitrogênio em cobertura na qualidade fisiológica e sanitária de sementes de painço, cv. AL Tibagi, produzidas em condições de campo. As sementes foram produzidas no período de dezembro de 2005 a fevereiro de 2006 e as avaliações laboratoriais realizadas de março a agosto de 2006. O delineamento experimental foi de blocos ao acaso, em esquema fatorial 4 x 2, constituído pela combinação de quatro doses (0, 30, 60 e 120 kg ha-1 de N) e duas épocas de aplicação (14 e 28 dias após a emergência - DAE) do fertilizante nitrogenado (uréia) em cobertura, com quatro repetições. A aplicação de N aumentou o vigor das sementes, expresso pelos testes de envelhecimento acelerado e emergência em campo. A aplicação de nitrogênio aos 28 DAE da cultura do painço proporciona maiores IVE e porcentagem de emergência em campo. A sanidade de sementes de painço não é influenciada pelas doses e épocas de aplicação da adubação nitrogenada.

A atenção em Saúde Mental em municípios de pequeno e médio portes: ressonâncias da reforma psiquiátrica

A partir da análise da Política Nacional de Saúde Mental formulada nos últimos anos e das experiências desenvolvidas após 1987 no país, procura-se compreender como o Sistema Único de Saúde tem contribuído ao avanço da reforma psiquiátrica nos municípios; verificar como a assistência oferecida nesses municípios está viabilizando os princípios da reforma psiquiátrica e a melhora das condições de vida dos usuários, bem como pesquisar o papel dos trabalhadores e gestores na construção de novas práticas de cuidado em Saúde Mental. A análise das práticas discursivas aponta que os vários segmentos sociais envolvidos na Saúde Mental conhecem os princípios e propostas da reforma psiquiátrica. No entanto, as gestões municipais não assumem integralmente as propostas do Ministério da Saúde para a área, sob a alegação de falta de recursos financeiros para a contrapartida exigida. Os usuários e familiares têm aos poucos assumido as novas propostas de intervenção, mas os mecanismos de participação e organização popular ainda são incipientes. Por fim, deve-se destacar que, para uma efetiva consolidação das propostas atuais da reforma psiquiátrica, é necessário um maior compromisso dos gestores com a atenção em Saúde Mental, maior investimento nas equipes multiprofissionais, o estímulo à organização e à participação dos usuários e familiares e a integralidade dos dispositivos de saúde, de assistência social e de cultura existentes nas cidades.

Problematizando a Reforma Psiquiátrica na atualidade: a saúde mental como campo da práxis

Mental Health, in the form of the Psychiatric Reform, and the Anti-Asylum Movement do not ignore the production of knowledge about that field, mainly due to the consolidation of Public Health as a field of knowledge. The article explores some authors who consider Mental Health as a new field of knowledge, introducing a new paradigm in the perception of health - Disease and Care -; however, the goal is to introduce Psychosocial Care as a means to enforce the transdisciplinary and multiprofessional practices. The possibility is that mental health produces developments in Health, consolidating the public policies. In practice, the hospital-centered and drug-based model still predominates, and there are setbacks to be overcome by taking advantage of loopholes capable of breaking with what is instituted.

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

Reforma a vapor catalítica do metano: Otimização da produção e seletividade em hidrogênio por absorção in situ do CO2 produzido

Topics of research related to energy and environment have significantly grown in recent years, with the need of its own energy as hydrogen. More particularly, numerous researches have been focused on hydrogen as energy vector. The main portion of hydrogen is presently obtained by reforming of methane or light hydrocarbons (steam, oxy, dry or auto reforming). During the methane steam reforming process the formation of CO2 undesirable (the main contributor to the greenhouse effect) is observed. Thus, an oxide material (sorbent) can be used to capture the CO2 generated during the process and simultaneously shifting the equilibrium of water gas shift towards thermodynamically more favorable production of pure hydrogen. The aim of this study is to develop a material with dual function (catalyst/sorbent) in the reaction of steam reforming of methane. CaO is well known as CO2 sorbent due to its high efficiency in reactions of carbonation and easy regeneration through calcination. However the kinetic of carbonation decreases quickly with time and carbonation/calcination cycles. A calcium aluminate (Ca12Al14O33) should be used to avoid sintering and increase the stability of CaO sorbents for several cycles. Nickel, the industrial catalyst choice for steam reforming has been added to the support from different manners. These bi-functional materials (sorbent/catalyst) in different molar ratios CaO.Ca12Al14O33 (48:52, 65:35, 75:25, 90:10) were prepared by different synthesis methodologies, among them, especially the method of microwave assisted self-combustion. Synthesis, structure and catalytic performances of Ni- CaO.Ca12Al14O33 synthesized by the novel method (microwave assisted selfcombustion) proposed in this work has not being reported yet in literature. The results indicate that CO2 capture time depends both on the CaO excess and on operating conditions (eg., temperature and H2O/CH4 ratio). To be efficient for CO2 sorption, temperature of steam reforming needs to be lower than 700 °C. An optimized percentage corresponding to 75% of CaO and a ratio H2O/CH4 = 1 provides the most promising results since a smaller amount of water avoids competition between water and CO2 to form carbonate and hydroxide. If this competition is most effective (H2O/CH4 = 3) and would have a smaller amount of CaO available for absorption possibly due to the formation of Ca(OH)2. Therefore, the capture time was higher (16h) for the ratio H2O/CH4 = 1 than H2O/CH4 = 3 (7h) using as catalyst one prepared by impregnating the support obtained by microwave assisted self-combustion. Therefore, it was demonstrated that, with these catalysts, the CO2 sorption on CaO modifies the balance of the water gas-shift reaction. Consequently, steam reforming of CH4 is optimized, producing pure H2, complete conversion of methane and negligible concentration of CO2 and CO during the time of capture even at low temperature (650 °C). This validates the concept of the sorption of CO2 together with methane steam reforming

Tratamento do Centro de Atenção Psicossocial para usuários de álcool e outras drogas CAPSad II Leste Natal/RN : uma avaliação da efetividade

The treatment for abusive users of alcohol and other drugs suffered significant modifications until arriving to the psychosocial model that is used by Centro de Atenção Psicossocial CAPSad II Eastern Natal/RN (Psychosocial Support Center). That model appears starting from Brazilian sanitary and psychiatric reforms which are expressed in the principles and propositions of Sistema Único de Saúde SUS (Unique System of Health). The Psychiatric Reform meant a rupture with the mental hospital and hospital centered treatment pattern which was destined to the abusive users of alcohol and other drugs. The new proposal offers the universalization, democratization, regionalization and completeness of the actions in the field of mental health. It gathers a strictly interdisciplinary health staff. The purpose of this study is to evaluate the effectiveness of the treatment for abusive users of alcohol and other drugs offered by CAPSad II Eastern Natal/RN. The evaluation used, as priority, the qualitative social research through an evaluating study starting from the non-experimental model. The methodological process used different instruments of data collection: bibliographical and documental researches, systematic observations at CAPSad II Eastern Natal/RN and, mainly, the semistructured interviews (21) that were accomplished with the professionals, users and relatives of CAPSad II Eastern Natal/RN. The investigation showed the effectiveness of the service and, therefore, CAPSad II Eastern Natal/RN constitute itself as the main confronting strategy to the mental hospital and hospital centered treatment pattern of caring the abusive users of alcohol and other drugs

Desnudando as condições para materialização da reforma psquiátrica em Natal/RN: para além da implantação dos serviços substitutivos em saúde mental

Esta pesquisa objetivou analisar a concretização da reforma psiquiátrica em natal, partindo de um dos serviços substitutivos que compõe a rede psicossocial deste município. A política de saúde mental tem passado por mudanças paradigmáticas, definindo como objetivo maior o processo de desistitucionalização. Redirecionando sua ação para os serviços substitutivos e não, mas o hospital psiquiátrico tradicional. Nesse cenário os Centros de Atenção Psicossocial (CAPS) se mostram estratégicos para materialização dos objetivos pretendidos pela reforma psiquiátrica. O estudo transcorre dentro da perspectiva materialista dialética. A presente pesquisa teve como lócus de investigação empírica o primeiro Centros de Atenção Psicossocial implantado em Natal/RN. A escolha por um serviço extra-hospitalar vai ao encontro de uma postura defendida pelo movimento de Reforma Psiquiátrica. Considerando o CAPS um serviço substitutivo estratégico em saúde mental para a efetivação da Reforma Psiquiátrica, neste sentido objetivamos apreender as contradições que marcam o processo de concretização da Reforma Psiquiátrica através da vivência dos usuários e de suas famílias, no interior de uma unidade integrante do novo modelo de atenção em saúde mental. Partimos do pressuposto de que os usuários e seus familiares são sujeitoschave no processo de reforma psiquiátrica, por vivenciarem em seu cotidiano as mudanças concretas realizadas, que acenam para um processo de re-inserção social, mas também, contraditoriamente, os limites e entraves desse processo

Ecossocialismo: a gênese de uma ecologia social em assentamentos de reforma agrária a partir dos movimentos sociais do campo

The world`s ecology crisis has in the capitalism way of production one of the possible causes. The unstopped search for the profits, into unlimited exploration of limited resources, made a huge transformation in human relationships with the nature, causing environment devastation, shortage of resources and species disappearance. Arises the necessity of question the society model that we are and which brings this crisis state, while we are impelled to search an alternative way. The ecosociallist praxis blows marxist principles with ecological matters, bringing important contributions regarding alternatives to capital/exploratory modus, advocating for a social fair society and environmentally sustainable. This way, by bibliographic review, we will research about this theory which have been growing in academic middles. In the same way, we will analyze the rural social movements paper in the construct of this reality. Throut the half estruture interviwes, bibliografic research and visities in the space of settlement called Moacir Lucena, that is today a exemple of rural resignification
