Entre o sol e a liberdade impera a violência: formação de redes para a ação a partir da estratégia saúde da família

The research aimed to analyze the feasibility of forming a network of municipal services to prevent and treat child victims of violence from the Basic Health Units in the Family Mossoró / RN. The research is a qualitative approach and was developed in the form of action research. The population was composed of representatives of institutions of the child and primary care professionals. Data were collected through questionnaires, workshops and semi-structured interview. The results were analyzed from data collected through the questionnaire designed to assess the material, lectures, dialogues and assessments with the team and presented in accordance with the findings of the research. The study was approved by the Ethics in Research UFRN with protocol No. 158/2010, CAAE: 0176.0.051.000-10. Situational diagnosis in the participants answered a questionnaire to characterize and then launched the guiding question of the focus group FHS While professional what your perception towards violence against children? It was felt the fear and ignorance on the part of the unit staff on how to prevent and to refer cases of violence against children and adolescents in the area of coverage of the unit and also realized that the professionals felt victims of occupational violence before the violence has reached proportions that the area of the unit. Mind the need to change strategies to work to combat violence, we plan to conduct focus group workshop to complete the questionnaire, training for protection against occupational violence, and meeting with other bodies responsible visor protecting children and adolescents to draw the flowchart of the victims in safety net. The next moment training to fill the notification form professionals were interested in learning and use this tool to combat violence. At the third meeting in Unity, meeting with representatives of the Child Protection Council, the professional unit showed interest in interacting with the agency to expose and combat violence against children and adolescents. Due to difficulties in the physical structure of the unit was not possible to continue the research and planned every moment, and then completed the data collection with interviews with the participating professionals, to assess the meetings. Therefore, it is considered that action research has also achieved its goals because the team was involved in the collective construction of a proposed change in the practices of referral and prevention of violence against children and adolescents. This involvement was favored using the principles Freirian during the course of the study. However, it is assumed that the network was not fully implemented because it is known that it is in a continual process of improvement and must continue evolving with the unit team.

Estimativa do balanço térmico por radiação em vacas Holandesas expostas ao sol e à sombra em ambiente tropical

É apresentado um método para a estimativa do balanço térmico por radiação em vacas da raça Holandesa expostas ao sol e sob a sombra em uma pastagem, com o objetivo de estabelecer um padrão morfológico mais adequado para esses animais em região tropical. O método envolve a determinação das características do pelame (área de superfície de malhas negras, espessura da capa, comprimento e diâmetro dos pêlos, número de pêlos por unidade de área), temperatura da superfície da capa e da epiderme e variáveis ambientais (irradiância solar, temperatura do ar e de globo, vento). Foi determinada a quantidade de radiação de ondas curtas efetivamente transmitida através do pelame e que atinge as camadas profundas da epiderme. Demonstrou-se, por intermédio de um exemplo prático, que as áreas de pelame negro apresentaram balanço radiante mais elevado que as áreas brancas, mas estas últimas possuiam maior transmissividade para a radiação de ondas curtas. Animais predominantemente negros foram melhor protegidos contra a radiação de ondas curtas que os predominantemente brancos, especialmente quando a capa de pelame é pouco espessa (até 4 a 7 mm), mais adequada para ambientes tropicais.

Efeito do ácido lático sobre as características microbiológicas, físico-químicas e sensoriais na carne do sol

The dried beef is a food traditionally eaten by Northeastern and has an extensive trade in the city of Natal-RN. It is usually produced in an empirical manner, without any standardization in production. Characterized as partially dehydrated meat product, so that the activity of water present is not sufficient to prevent microbial growth, degradation or the production of microbial toxins. The guarantee that the market dried beef is to provide a quality product hygienic, microbiological, physicochemical and sensory stable and adequate for the safety and consumer satisfaction, which has been increasingly attracted to food with natural preservatives. Thus, the meat industries are replacing the current seasonings and natural preservatives for similar, with it without affecting the shelf life of products. Lactic acid has been used to meet these requirements. In this sense, this study aimed to evaluate the effect of lactic acid on the physico-chemical, microbiological and sensory, besides knowing the consumer profile of dried meat of the City of Natal / RN. The results demonstrated that the use of lactic acid in concentrations of 1% and 2% during the processing of dried meat, had statistically significant effect (p < 0.05) on the physico-chemical (pH and water activity) and consequently reduced the microbial count does not alter the taste of the new product developed. Regarding the results on the consumer profile, it was found that the majority of respondents (71.75%) did not observe the presence of the stamp of the Federal Inspection Service (SIF) to buy this meat food that 81.55% of consumers check the hygiene conditions of the site and handlers, however, a large proportion of respondents not concerned with the guarantee of origin of typical regional products featuring a hazard to food safety for consumers of the city of Natal-RN

Efeitos da previdência rural na agricultura familiar da microrregião Serra de São Miguel - RN

The objective of the present work is to verify the effects of Rural Social welfare in the family agriculture of the microrregião Serra de São Miguel-RN. The study based on available bibliography on the theme, in secondary data and in a rising amostral accomplished in three municipal districts (Encanto, São Miguel and Riacho de Santana) of the microrregião. The universe of the study was the establishments of the family agriculture appeared in the Agricultural Census of 2006, in those municipal districts. The unit of considered analysis was the rural family, with the interviews being applied close to the farmers' families with and without retired rural. The sample was of 94 present families in the family establishments. The results demonstrate that the Rural Precaution reaches a significant covering degree in the rural area of the researched municipal districts, with an average of 1,57 beneficiaries for home in the families with retired. The data of the research attest that the family agriculture in the microrregião Serra de São Miguel-RN it has few favorable conditions for his/her development, once, besides the shortage of lands and of the climatic factor of the area, the returned public politics the family farmers' totality - like PRONAF and PAA -, it has been unable to give effective answers for the improvement of the life conditions in the rural way, have seen the minimum amount of families reached by those politics, be in function of the drawing or of the atmosphere where they are done. In this context, he/she stands out the importance of the Rural Precaution that, in function of the application of the constitutional devices that you/they guaranteed his/her universalization, it has been the only relevant public politics that, in fact, it has been reaching her/it all their beneficiary potentials. Given the general situation of the family agriculture of the microrregião and of the specific characteristics of the researched family establishments, the hypothesis was corroborated that the rural retirement doesn't contribute directly to the increase / making possible of the family agriculture. In spite of 57,4% of the families with retired have declared to use resources of the retirement in the costing of the rural activity carried out by the family, the annual medium value of the expense just located around 7,02% of the annual value of the retirements gained by the families in the year of 2010. Data the low levels in that the social reproduction of the great majority of the family establishments of the microrregião, the maintenance of the families is operated represents the main destiny of the resources precautions. It was also confirmed the hypothesis that the Rural Precaution constitutes the main monetary contribution of the families with retired. For more than 93% of the families with retired, the retirements doing 50% or more of the total of the family monetary income, and in the composition of the rural income of the families with retired and pensioners, the originating from income the rural retirements are equal to 65,24% of the total of the annual income obtained by the families. It is ended, because, that the rural precaution, given to the adversities for the development of the family agriculture, of the operational inefficacy of the public politics and of the few opportunities of generation of existent income in the local savings, it is the main responsible for the reduction of the poverty and, consequently, for the improvements of the conditions of life of the families of and with seniors in the rural way of the microrregião Serra de São Miguel-RN

Immobilization of streptavidin in sol-gel films: Application on the diagnosis of hepatitis C virus

Recent advances have accelerated the development of biosensors for the analysis of specific gene sequences. In this kind of biosensor, a DNA probe is immobilized on a transducer and the hybridization with the target DNA is monitored by suitable methodology. In the present work, the streptavidin (STA) was encapsulated in thin films siloxane-poly(propylene oxide) hybrids prepared by sol-gel method and deposited on the graphite electrode surface by dip-coating process. Biotinylated 18-mer probes were immobilized through STA and a novel amperometric DNA biosensor for the detection and genotyping of the hepatitis C virus (genotypes 1, 2A/C, 2B and 3) is described. The HCV RNA from serum was submitted to reverse transcriptase-linked polymerase chain reaction (RT-PCR) and biotin-labeled cDNA was obtained. Thus, the cDNA was hybridized to the target-specific oligonucleotide probe immobilized on the graphite electrode surface and following the avidin-peroxidase conjugate was added. The enzymatic response was investigated by constant potential amperometry at -0.45 V versus Ag/AgCl using H2O2 and KI solutions. HCV RNA negative and positive controls and positive samples of sera patients were analyzed and the results were compared to commercial kit. The proposed methodology appeared to be suitable and convenient tool for streptavidin immobilization and diagnose of HCV disease. (c) 2006 Elsevier B.V. All rights reserved.

Photoluminescence of Eu(3+) ion in SnO(2) obtained by sol-gel

Photoluminescence data of Eu-doped SnO(2) xerogels are presented, yielding information on the symmetry of Eu(3+) luminescent centers, which can be related to their location in the matrix: at lattice sites, substituting to Sn(4+), or segregated at particles surface. Influence of doping concentration and/or particle size on the photoluminescence spectra obtained by energy transfer from the matrix to Eu(3+) sites is investigated. Results show that a better efficiency in the energy transfer processes is obtained for high symmetry Eu(3+) sites and low doping levels. Emission intensity from (5)D(0) -> (7)F(1) transition increases as the temperature is raised from 10 to 240 K, under excitation at 266 nm laser line, because in this transition the multiphonon emission becomes significant only above 240 K. As an extension of this result, we predict high effectiveness for room temperature operation of Eu-based optical communication devices. X-ray diffraction data show that the impurity excess inhibits particle growth, which may influence the asymmetry ratio of luminescence spectra.
