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

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.

Evaluation of Bulk and Surfaces Absorption Edge Energy of Sol-Gel-Dip-Coating SnO2 Thin Films

The absorption edge and the bandgap transition of sol-gel-dip-coating SnO2 thin films, deposited on quartz substrates, are evaluated from optical absorption data and temperature dependent photoconductivity spectra. Structural properties of these films help the interpretation of bandgap transition nature, since the obtained nanosized dimensions of crystallites are determinant on dominant growth direction and, thus, absorption energy. Electronic properties of the bulk and (110) and (101) surfaces are also presented, calculated by means of density functional theory applied to periodic calculations at B3LYP hybrid functional level. Experimentally obtained absorption edge is compared to the calculated energy band diagrams of bulk and (110) and (101) surfaces. The overall calculated electronic properties in conjunction with structural and electro-optical experimental data suggest that the nature of the bandgap transition is related to a combined effect of bulk and (101) surface, which presents direct bandgap transition.

Nanopore size growth and ultrafiltration performance of SnO2 ceramic membranes prepared by sol-gel route

Supported ceramic membranes have been produced by the sol-casting procedure from aqueous colloidal suspensions prepared by the sol-gel route. Coatings on a tubular alumina support have been successfully performed leading to crack free layers. Samples have been sintered at 400, 500 and 600 degreesC, and the effect of heating treatment on the nanostructure and on the ultrafiltration properties are analyzed. The characterization has been done by high resolution scanning electron microscopy, nitrogen adsorption-desorption isotherms, water permeation and cut-off determination using polyethylene glycol standard solutions. The micrographs have revealed that grains and pore size increase with the temperature, whereas their shape remains invariant. This results is in agreements with N-2 adsorption-desorption analyses, which have revealed that the mean pore size diameter increases from 4 to 10 nm as the sintering temperature increases from 400 to 600 degreesC, while the total porosity remains constant. Furthermore, the tortuosity, calculated from water permeability, is essentially invariant with the sintering temperatures. The membranes cut-off, determined with a retention rate equal to 95%, are 3500, 6500 and 9000 g . mol(-1) for 400, 500 and 600 degreesC, respectively, showing that the permeation properties of SnO2 ultrafiltration membranes can easily be controlled by sintering condition.
