Os processos comunicacionais nas rádios comunitárias legalizadas do sertão do Piauí

O trabalho reflete sobre os processos comunicacionais das 30 primeiras rádios comunitárias legalizadas do sertão do Piauí. Procura traçar o panorama dessas emissoras, identificar as rádios que têm mais vínculos e atuação comunitária e também analisar seus papéis sociais e diferenças. Objetiva-se ainda seus processos comunicativos, além de mapear e fornecer visão do funcionamento de cada emissora, entender como ocorre a participação das comunidades, a visão do fazer radialismo e o significado das emissoras consideradas emblemáticas no fazer comunitário. Metodologicamente adota-se o método qualitativo, o qual foi desenvolvido com base em pesquisa bibliográfica, estudo documental e pesquisa de campo, cujas técnicas usadas foram: estudos de produção bibliográfica e de documentos virtuais e hemerográficos e realização de entrevistas semi-estruturadas presenciais com membros das emissoras. As rádios comunitárias pesquisadas têm ampla importância nos espaços em que estão instaladas porque contribuem difundindo informação local e favorecendo o debate sobre novas demandas de cidadania e novos rumos para a região sertaneja piauiense.(AU)

Estratégias de cuidados por familiares de portadores de transtornos mentais severos residentes na zona rural do alto sertão paraibano

In the current configuration of the Brazilian Psychiatric Reform, family plays a key role in mental health care: shared responsibility and active participation in the process of rehabilitation of people with severe mental disorders. It´s considered that the family member who cares can help users in their daily tasks and articulating trajectories, networks and ways to potentiate social connections. This research was motivaded by interest in the subject and by the lack of research and studies about this reality in rural areas. This study aimed to identify ways of mental health care by relatives of severe mental disorder patients living in rural zone located at sertão of Paraiba. Methodologically was made a work with qualitative research structured in two moments. In the first one, was held a Documentary Research in CAPS II in order to identify: a) users living in rural that had a history of at least one psychiatric hospitalization, b) users who no longer use the reference service (CAPS II) for at least one year. The second stage consisted by home visits and semi-structured interviews with eleven families in rural areas. Results pointed out a profile composed by 56 users: 56 women and 26 men aged between 50 and 64 years, unmarried, without study, farmers and housewives, living six miles from CAPS II and carriers with severe mental disorders. Strategies and resources used by the families for mental health care were: religion, work, medication and help from relatives, neighbors and community. Factors related to non-use of substitute services were lack of internment in CAPS II and lack of money and transportation. The hospital, the house arrest, the police aid and religion were strategies used by family members as support to psychiatric crises. The data pointed to non-solving of care offered by psychosocial support network and the importance of redirecting practices aligned to the asylum model in favor of psychosocial strategies that aimed at rehabilitation and community participation in mental health care

Dar a ver Sertão e Sevilha: matizes hispânicas na poética de João Cabral de Melo Neto

Dar a ver Sertão e Sevilha: matizes hispânicas na poética cabralina is a study on the lyric reading possibilities of Cabralian poetry, from the work of the poet from Pernambuco, that shows the intercultural dialogue and the Spanish poetical approach absorbed by João Cabral de Melo Neto during his Andalusian experience. Hispanic interfaces incorporated by the Cabralian poetry through literature or through the direct contact with the culture are registered on the 133 poems that have Spain as theme, in which we can see the matrix of Hispanic tradition, rich in its diversity, was the preponderant element for the poet João Cabral to discover the core of his lyric backwards. From Hispanic corpus, it will be explored the aesthetical assimilation of Spanish poetry in the work of João Cabral de Melo Neto, with the objective of demystifying the issues of lyrical dullness and anti musicality on Cabralian poetics in which, from the appropriation of Hispanic elements investigated as a signal of lyrics and musicality, originates a reading unattached from the constructivist signal, tessitura evidenced by the critic Antonio Candido since the origin of JCMN poetry with the poem Pedra do sono (1942). The mentioned aesthetics was adopted later on by the literary critics that named it as “brain poetry” for its hermetical configuration, tessitura of rigor, concreteness of language and stiff metrics. The results obtained from this study aim to induce a reading that favors the lyrical acoustic of the Cabralian poetry in the effort to ease the aspects of the arid construction.

Onde fica o sertão rompem-se as águas: processo de territorialização da ribeira do Apodi-Mossoró (1676-1725)

The Portuguese territorial process of the captaincy of Rio Grande was initiated in1598 with the conquest of the Potengi River bar by Mascarenhas Homem. This process lasted until 1633, when it was interrupted by the arrival of the Dutch, and resumed only in 1654. From this year on, the occupation of unknown lands of the captaincy was encouraged, supporting the advancement towards conquering the backlands, breaking the divisive boundaries with the captaincy of Siará Grande so far known: the Assú riverside. This breakthrough resulted in confrontations with the inhabitants of these lands, known as tapuias, leading to outbreak of several conflicts that composed the Barbarians War. The main stage of such events in Rio Grande, between the years 1687 and 1720, was precisely the Assú riverside, one of the spaces to be investigated by this research. Therefore, this paper aims to analyze the advance of the conquerors in Rio Grande, contributing to the territorial process, which resulted in the emergence of a new border between Rio Grande and Siará Grande: the Apodi-Mossoró river. For this purpose, it was used sources produced between the years 1659 and 1725, as the settlement letters, royal charters, correspondence between the City Council of Natal, captains of Rio Grande and the government of Pernambuco and also the general government, as well as the documents related to the militia composed mainly by Paulistas who struggled in the captaincy.

Efeito do consumo de farinha de linhaça (Linum usitatissimum) no crescimento de ratos Wistar e relação com a digestibilidade de globulinas e fatores antinutricionais protéicos

Linseed is an important oilseed consumed raw as nutritional supplement, that although represents a rich source of nutrients, its nutritional value could be impaired due to the presence of antinutritional factors. In this study, protein fractions from raw linseed flour were extracted and isolated being obtained 12% of albumins, 82% of globulins, 5% of glutelins and 1% of prolamins. These proteins were visualized by SDS-PAGE and albumins showed low molecular mass protein bands around 21 kDa and minor bands, similar to that of trypsin inhibitor; Globulins presented protein bands with high molecular masses, which possibly are constituents of multimeric proteins, such as legumins. After determination of the centesimal composition of raw linseed, it was used as exclusive protein source for young rats to evaluate its effect on animal growth. The results showed negative effects on rat growth (weight gain 73% less than the control group) and reduction of intestinal villus (35%), that could be related with in vitro and in vivo globulin digestibility and proteinaceous antinutritional factors (mammalian digestive enzymes inhibitors and lectins) in albumin fraction. Native globulins showed, by SDS-PAGE, low susceptibility in vitro to trypsin and chymotrypsin, however presented high degradation by pancreatin. Thermal treatment of globulins for 5 and 15 minutes at 100ºC improved considerably its digestibility by trypsin and pancreatin. Globulins presented 93.2% in vivo digestibility, similar to the control protein. Albumin fraction had high trypsin inhibition activity (100%) and chymotrypsin inhibition of 28.3%; haemagglutinating activity was not detected. The results of this study indicate the negative action of trypsin inhibitors on animal growth, but can not be discarded its combined action with other antinutritional factors, which could compromise the raw linseed utilization as an alternative food

Variabilidade físico-química da farinha de mandioca do Território da Cidadania do Vale do Juruá, Acre.

A farinha é um derivado da mandioca de grande importância alimentar, porém com pequena padronização, por causa do processo artesanal de fabricação. O objetivo deste estudo foi analisar a variabilidade da farinha de mandioca artesanal, produzida no Território da Cidadania do Vale do Juruá, Acre, e agrupar os municípios produtores de acordo com suas características físico-químicas, por meio de análises multivariadas, determinando sua influência na qualidade da farinha de mandioca. Foram analisadas 138 amostras de farinhas, coletadas nos municípios de Cruzeiro do Sul, Mâncio Lima, Rodrigues Alves, Porto Walter e Marechal Thaumaturgo, com determinação da umidade, cinzas, proteína total, extrato etéreo, fibra total, carboidratos totais, valor energético, acidez titulável, pH e atividade de água. Os dados foram analisados pela estatística descritiva com comparação de médias pelo teste de Tukey e estatística multivariada, de forma complementar entre si; com análises de agrupamento hierárquica, pela distância euclidiana e método de Ward, e, não hierárquica, k-means, análise de componentes principais, pela matriz de correlação, e análise discriminante, pelo método da exclusão progressiva passo a passo. Os resultados mostraram que as farinhas encontram-se dentro das normas de qualidade exigidas em legislação. As diferentes análises multivariadas foram coerentes, indicando que há um padrão de distribuição das características físico-químicas das farinhas, o que sugere padrões no processo de fabricação, distribuídos conforme a localização dos municípios analisados. As características de maior influência na discriminação das farinhas são acidez, pH, atividade de água e umidade, indicando que o modo de fabricação tem grande influência na qualidade da farinha produzida.

Inclusão de farinha de resíduos da indústria de filetagem de tilápias na alimentação de girinos de rã-touro (Rana Catesbeiana Shaw,1802)

The objective of this experiment was to evaluate the inclusion of meal of tilapia industrial waster in bullfrog tadpoles' diets (Rana Catesbeina Shaw, 1802). Two hundred fifty tadpoles with initial weight and length of 0,18 +/- 0,05g and 2,50 +/- 0,18 centimeters were used, respectively, they were used and distributed in 25 aquariums of 30 liter each in a complete randomized design with five treatments and five repetitions. The tadpoles were fed four times a day with diets containing 0, 5, 10 and 15% of inclusion of tilapia filleting and another diet with 0% of supplemented tilapia filleting with synthetic methionine, being supplied four times a day at ease. The experiment period was 30 days. The diets with tilapia filleting inclusion and methionine supplementation did not have influence in the final weight and length averages, feed survival and conversion of bullfrog tadpoles. It cam be used until 15% of tilapia filleting inclusion in the bullfrog tadpoles food. The synthetic methionine supplementation in diets for bullfrog tadpoles is not necessary in diets with levels over 0,471/4 of the total methionine.

Substituição da farinha de peixe pelo farelo de soja em dietas para juvenis de curimba

Replacement of fishmeal by soybean meal in juvenile curimba (Prochilodus lineatus) diets was evaluated. Five isonitrogenous (26% crude protein) and isocaloric (4,000 kcal of gross energy kg(-1)) diets with 0, 25, 50, 75 and 100% of replacement were used. Fish (3.71 +/- 0.54 g) were distributed in 25 tanks (120 liters). The diets were provided for 84 days. Total replacement of fishmeal (100%) by soybean meal worsened weight gain, feed conversion and protein efficiency ratio. An increase in carcass fat was observed at the expense of reducing protein percentage, as well as an increase in hepatosomatic index. It was concluded that replacing 75.0% fish meal by soybean meal (33.2% of inclusion) did not affect the animal growth, although there been observed changes in corporal composition and hepatic hyperplasia.

Farinha de resíduos da indústria de filetagem de tilápias como fonte de proteína e minerais para alevinos de tilápia-do-nilo (Oreochromis niloticus)

Neste trabalho, objetivou-se avaliar a utilização da farinha de resíduos da indústria de filetagem de tilápias (FR) como fonte de proteína e de minerais em rações práticas na alimentação de alevinos de tilápia do Nilo. Foram utilizados 120 alevinos de tilápias do Nilo com peso e comprimento iniciais de 0,58 ± 0,05 g e 3,49 ± 0,09 cm, respectivamente, distribuídos em 24 aquários com capacidade para 30 L, em um delineamento inteiramente casualisado, com quatro tratamentos e seis repetições. Os peixes foram alimentados com rações contendo 30% de proteína digestível e 3.000 kcal de energia digestível/kg, de acordo com os seguintes tratamentos: CO - ração à base de milho e farelo de soja, sem suplementação de fósforo; FB - ração à base de milho e farelo de soja, com fosfato bicálcico; FB + FR - ração à base de milho e farelo de soja, suplementada com fosfato bicálcico (50%) e farinha de resíduos (50%); FT - ração à base de milho e farelo de soja, suplementada com farinha de resíduos. Ao final do experimento, os melhores resultados de desempenho foram observados nos animais que receberam suplementação de P. Quanto às características de carcaça, os animais que receberam a ração CO apresentaram maior teor de gordura corporal e menores teores de cinzas, Ca e P. A FR pode ser utilizada em rações para alevinos de tilápia do Nilo como fonte de P, sem prejuízos no desempenho e na composição corporal.

Farinha de vísceras de aves em rações para a tilápia do Nilo (Oreochromis niloticus L.) durante a fase de reversão sexual

Neste trabalho, objetivou-se avaliar o desempenho, a sobrevivência e a efetividade de reversão de larvas de tilápia do Nilo (Oreochromis niloticus L.) alimentadas com rações contendo níveis crescentes de inclusão de farinha de vísceras de aves (FVA). Utilizou-se 500 larvas de tilápia do Nilo com dois dias de idade, distribuídas em um delineamento inteiramente casualizado com cinco tratamentos e cinco repetições, sendo a unidade experimental constituída por um aquário de 30 L com 20 larvas. Foram elaboradas cinco rações com cinco níveis de inclusão de FVA ( 0; 20; 40, 60% e 60% mais lisina sintética). Foram elaboradas rações isocalóricas, isocálcicas, isofosfóricas e isoprotéicas, com 60mg de a-metiltestosterona/kg, 38,6% de proteína digestível e 3.700 kcal de energia digestível/kg, de modo que a ração com inclusão de lisina foi isoaminoacídica para lisina em relação à ração sem a inclusão de FVA. O arraçoamento foi realizado quatro vezes ao dia, ad libitum. Ao final, foram avaliadas as médias de peso final (PF), comprimento total (CT), sobrevivência (SO) e efetividade de reversão (ER). Foi observado aumento linear no PF e CT com o aumento da inclusão da FVA na ração, enquanto, para SO, a ração sem FVA foi inferior às demais. As rações sem inclusão de FVA e com 20% de inclusão de lisina proporcionaram PF e CT médios inferiores e somente a ração sem FVA foi inferior para SO. Conclui-se que a FVA pode ser utilizada em rações para a tilápia do Nilo durante a reversão sexual.

Ocorrência da infecção por Toxoplasma gondii e avaliação da imunização em caprinos do sertão do cabugi, Rio Grande do Norte

Toxoplasmosis is one zoonosis caused by Toxoplasma gondii protozoan. Goats, amongst the production animals, are one of the species most susceptible to this parasite, being one them main involved agents in ovine and goat abortions, determining great economic losses and implications for public health, since the presence it parasite in the products of goat origin, consist in one of the main sources of infection for the man. In this study 244 blood samples in 8 farms situated in 4 cities from the Sertão do Cabugi region, Rio Grande do Norte State, northeast of Brazil and, tested by ELISA assay. The results had shown a prevalence of 47.13% for anti- T. gondii antibodies and a significant association between positivity and variable evaluated as age, locality and property. The IgG avidity assay evaluated in 115 positive samples was carried to discriminate acute and chronic infection. Twelve samples (10.4%) had presented antibodies of low avidity while 103 (89.6%) presented high avidity antibodies; indicating that most of the animals was precocious exposure to the parasite. Significant difference was verified only for the variable sex. We also evaluate the capacity of recombinant adenoviruses codifying SAG1, SAG2, SAG3 and CMV in inducing activation of specific immune response in goat. These 109 animals received 109 pfu of the AdSAG1, AdSAG2, AdSAG3, AdCMV or PBS in vaccine protocol with 3 immunizations. Serum samples of the each animal, before and after mmunization, had been submitted to the ELISA. The results demonstrate that the immunizations had induced the production of IgG antibodies specific against T. gondii proteins
