Prejudice, Vulnerability, Adhesion Process, Religiousness Regarding the Life Routine with AIDS: Life Stories

Objective: To communicate life stories of people who suffer from acquired immunodeficiency-syndrome with a higher vulnerability registered at the Municipal Secretary of Social Assistance and the diagnostic’s influence on their daily routine. Method: Descriptive and exploratory study based on oral life history. Thirteen people with AIDs took part in the study via a semi-structured interview. The narratives were analyzed using Bardin’s thematic content analysis. Results: Three thematic axes emerged from Bardin’s content analysis: prejudice and discrimination regarding the life routine with aids; Reaction when facing the diagnostic and the adhesion process for the antiretroviral treatment; Confrontation of religion and religiousness on people with aids. Conclusion: The people living with aids, a chronic and stigmatizing disease, need the support of multidisciplinary teams and an improvement in relation to the access, the coverage and the meaning assigned to the disease, besides a better quality of life and social assistance. We conclude that religion did not contribute to facing these people’s conditions. It brought blame, incorrect information that may impair the treatment and their follow-up. One infers that health education regarding HIV/AIDS needs to be remodeled on all of society’s segments

Mapeamento da fitomassa da caatinga do seridó pelos índices de área de planta e de vegetação da diferença normalizada

Phytomass is a critical information for economic and environmental activities like the establishment of policies for timber resources, forest management, studies of plant nutrient cycling, CO2 sink, among other. The phytomass of a Caatinga area was obtained by an empirical method using normalized difference vegetation index (NDVI) of Landsat images, the plant area index (PAI) and the phytomass inventory. At a first stage, linear, logarithmic and non-linear models were developed and tested. Bush and tree specimens were considered in the study, so that most of the individuals that contribute to the spectral answer detected by satellite images were included. At a second stage, the orbital parameter NDVI was used to map the PAI, which was used to map the phytomass, based on the relationship of this phytomass as a function of PAI. The residues between measurements and estimates based on NDVI varied from 0 to 84%, while the residues of total dry weight of phytomass per ha obtained by mapping and by dendrometrical equations varied from 5 to 104%, with a large trend of 166 and 448% in open Caatinga areas, due to the contribution of the herbaceous stratum to NDVI.A fitomassa, principalmente arbórea, é informação necessária em atividades econômicas e ambientais, como políticas de uso do recurso madeireiro, manejo florestal, estudos de ciclagem de nutrientes, absorção de CO2, entre outros. A finalidade deste estudo foi a verificação de um método empírico para o mapeamento da fitomassa da Caatinga do Seridó, integrando-se um inventário de fitomassa, o índice de área de planta (IAP) e o índice de vegetação da diferença normalizada (NDVI), por meio de imagens Landsat TM. Na primeira etapa foram desenvolvidos e testados modelos lineares, logarítmicos e não lineares. A abordagem de tamanho foi arbustiva e arbórea, incluindo-se a maior parte dos indivíduos que contribuem na resposta espectral mensurada por imagens de satélite. Em uma segunda etapa utilizamos o parâmetro orbital, NDVI, para o mapeamento do IAP, que por sua vez, foi utilizado para mapear a fitomassa. Os desvios entre mensurações de IAP e estimativas a partir do NDVI, variaram de 0 a 84%, enquanto que os desvios entre Peso Seco Total de Fitomassa por ha obtidos pelo mapeamento e por equações dendrométricas, variaram de 5 a 104%, com grandes tendências de 166 e 448% para áreas de caatinga aberta, provocada pela contribuição do estrato herbáceo no NDVI

Popularization actions of food science and technology in south and metropolitan regions of Rio de Janeiro state.

The ignorance on concepts and practices in Food Science and Technology (FS&T) and the lack of specialized staff in agricultural educational institutions are factors that limit the interest of future technical on this topic. Such limitations may be overcome through actions to awaken curiosity and motivate the training technical to care for all matters of FS&T, constituting current educational techniques and encouraging the interest by potential agribusiness activity. Thus, was established a partnership between Embrapa Food Technology, Federal Institute of Education, Science and Technology of Rio de Janeiro - Campus Nilo Peçanha (IFRJ) and the Technical College of Rural University (CTUR). It was carried out a diagnosis of physical and educational structure of these institutions and localities conditions. Subsequently, the popularization of FS&T gave through five courses of capacitance, construction of web page and a discussion forum. It was constructed a network of relationships and communication that includes the actors concerned development in these localities and produced materials to disseminate these information. The point of views of the participants of courses and of the event were evaluated. The data showed that the activities were mostly positive and which are necessary new actions

CARACTERIZAÇÃO EPIDEMIOLÓGICA E HISTOPATOLÓGICA DAS NEOPLASIAS MAMÁRIAS DE FELINOS EM FORTALEZA E REGIÃO METROPOLITANA

Mammary neoplasms are one of the three most neoplasms common types in female domestic cats, with an occurrence of 20 cases and a frequency of 33.90% in animals aged 10 to 12 years. Factors such as the use of hormones, pseudocyesis, obesity, and a diet rich in lipids in the young phase may be a part of the etiology of this pathologyin cats. There is a high rate of malignancy in most feline mammary tumors, most being carcinomas corresponding to 42.86% of the cases. The most common benign neoplasms are adenomas. The prognosis is reserved for most cats, and death is usually caused by clinical effects secondary to the progression of the local disease (disease located in the mammarychain) or due to metastatic spread to vital organs. Thus, the diagnosis is of extreme importance for a good prognosis. The present work aimed at the epidemiological and histopathological characterization of mammary neoplasms in felines in the city of Fortaleza and its metropolitan region, analyzing data from 59 histopathological exams of mammary tissue samples of this species.As neoplasias mamárias são um dos três tipos neoplásicos mais frequentes nas fêmeas de gatos domésticos, sendo observada a ocorrência de 20 casos e frequência de 33,90% em animais com idade de 10 a 12 anos. Fatores como a utilização de hormônios, pseudociese, obesidade e alimentação rica em lipídeos na fase jovem podem estar envolvidos na etiologia desta patologia mamária em gatas. Existe um alto índice de malignidade na maioria dos tumores mamários felinos, sendo a maior parte carcinomas com 42,86% dos casos verificados. As neoplasias benignas mais comuns são os adenomas. O prognóstico é reservado para a maioria das gatas, sendo a morte geralmente causada por efeitos clínicos secundários à progressão da doença local (doença localizada na cadeia mamária) ou devido à disseminação metastática para órgãos vitais. Desta forma, o diagnóstico é de extrema importância para um bom prognóstico. O presente trabalho teve como objetivo a caracterização epidemiológica e histopatológica das neoplasias mamárias em felinos no município de Fortaleza e região metropolitana, fazendo uma análise de dados de 59 exames histopatológicos de amostras de tecido mamário desta espécie
