Síntese e caracterização de catalisadores baseados em vermiculita modificada com ferro: aplicação em processos do tipo foto-fenton

Clays are materials with specific properties that make them promising for various studies. In this work we used the vermiculite clay as support for iron compounds, in order to obtain promising materials for application in the heterogeneous type photo-Fenton process. In all, the study included six solid, starting from the vermiculite (V0) was obtained calcined vermiculite (V0-C), the mixed material (V0/β-FeOOH) formed by vermiculite more akaganeite, exchanged vermiculite (v0t-C), vermiculite impregnated Wet (V0u-C) and V0u-CL that is the solid obtained by impregnating with a back washing. The solids of the study had their physical and chemical characteristics investigated by the following characterization techniques: X-Ray Diffraction (XRD), Infrared Spectroscopy (IR), Energy Dispersive Spectroscopy (EDS), X-Ray Fluorescence Spectroscopy (XRF), UV-Vis by Diffuse Reflectance (DR UV-Vis), Thermogravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM). The V0 material showed three distinct phases, which are the very vermiculite, hidrobiotite and biotite, the last two phases are part of the geological of formation process vermiculite. The solids obtained after the modification showed an increase in the amount of iron present in the clay, these being quantities important for application in photocatalysis. The micrographs and EDS data, show that after treatment of addition of the metal , the iron was intercalary in structure of vermiculite for solid V0t-C and V0u-C, however, this did not occur with mixed material. In the photoFenton process, was observed a maximum removal of 88.8% of the dye methylene blue coloring for the catalyst V0/β-FeOOH, while for the other solids was obtained values between 76.8 and 62.6%, compared to 37.8% of discoloration without the presence of catalyst. Therefore, it is concluded that the vermiculite clay presents as a good catalyst and iron support for the, beyond of presenting a low cost because of its high abundance.

Otimização dos parâmetros de um modelo de bomba em sistemas de bombeio centrífugo submerso

One of several techniques applied to production processes oil is the artificial lift, using equipment in order to reduce the bottom hole pressure, providing a pressure differential, resulting in a flow increase. The choice of the artificial lift method depends on a detailed analysis of the some factors, such as initial costs of installation, maintenance, and the existing conditions in the producing field. The Electrical Submersible Pumping method (ESP) appears to be quite efficient when the objective is to produce high liquid flow rates in both onshore and offshore environments, in adverse conditions of temperature and in the presence of viscous fluids. By definition, ESP is a method of artificial lift in which a subsurface electric motor transforms electrical into mechanical energy to trigger a centrifugal pump of multiple stages, composed of a rotating impeller (rotor) and a stationary diffuser (stator). The pump converts the mechanical energy of the engine into kinetic energy in the form of velocity, which pushes the fluid to the surface. The objective of this work is to implement the optimization method of the flexible polyhedron, known as Modified Simplex Method (MSM) applied to the study of the influence of the modification of the input and output parameters of the centrifugal pump impeller in the channel of a system ESP. In the use of the optimization method by changing the angular parameters of the pump, the resultant data applied to the simulations allowed to obtain optimized values of the Head (lift height), lossless efficiency and the power with differentiated results.

Visita interprofissional da cardiologia: uma estratégia de educação interprofissional na área da saúde na Universidade Federal do Rio Grande do Norte

The interprofessional education still represents a great challenge for the health education. This paper aims at implementing the Interprofessional Cardiology Visit (VIC, acronym in Portuguese) as a teaching strategy for the interprofessional education in the undergraduate and graduate courses of UFRN (Federal University of Rio Grande do Norte, acronym in Portuguese). It is a prospective and exploratory study held from March 2013 to November 2014, in the cardiology department of HUOL (Portuguese acronym for Onofre Lopes University Hospital), including health professionals from the mentioned hospital (doctor, psycologist, physiotherapist, dentist, social assistant, nutritionist, pharmacist and nurse), undergraduate and graduate students from the health courses of UFRN. The study happened in three parts: interprofessional activity planning; Implementation of the activity “Interprofessional Cardiology Visit (VIC)”; and Activity evaluation, this last one was made through focus groups. The process of planning and implementation of the VIC was described during the implementation phase: 60 meetings in which 1324 participants discussed one specific patient per meeting. After each case presentation, an interprofessional discussion was held, pointing out each professional’s specific point of view towards improving the overall care of that discussed patient. From the focus group analysis, five categories emerged: Recognition of previous participations in interprofessional activities; Conceptual vision of interprofessional activities; Impacts of the VIC to the patient’s care; Contributions of VIC to the professional training; and Challenges of VIC continuation. The making and planning of VIC process has reached its goals, despite of some health professional’s participation not being systematic due to work overload, such as the nurses’ case, as well as schedule difficulties. The VIC was praised as a successful experience and considered an initiative with positive impact for improving the care of patients with heart diseases. It is clear, from analyzing the discourses, that the VIC is a strategy which positively impacts both the care and the teaching. However, some difficulties remain, such as the lack of human resources and the challenge of making it systematic.

Imunoexpressão da proteína endonuclease apurínica/apurimidínica (APE-1) em adenomas pleomórficos e carcinomas ex-adenomas pleomórficos

Introduction: Apurinic/Apyrimidinic Endonuclease 1 (APE-1) is an essential protein for DNA base excision repair (BER) pathway and regulation of redox activities. The ability of malignant cells to recognize and repair DNA damage is an important mechanism for tumor survival, and recent studies suggest that APE-1 overexpression is related to poor prognosis in some tumors. Purpose: To analyze the immunoreactivity of APE-1 in Pleomorphic Adenomas (PA) and Carcinomas Ex Pleomorphic Adenomas (CaExPA) of salivary glands. Materials and Methods: A total of 49 tumors fixed in formalin and embedded in paraffin (33 PA and 16 CaExPA) underwent immunohistochemical study by the immunoperoxidase technique. APE-1 immunoreactivity was evaluated quantitatively by the percentage of immunopositive cells. For statistical analysis a significance level of 5% (p≤ 0.05) was adopted. Results: All cases of PA and CaExPA (n=49) were positive for APE-1, however, there was a higher expression in CaExPA, with statistically significant difference (p<0.001). There was no association between APE-1 expression and tumors of major or minor salivary gland, however, not encapsulated PA (median expression = 54.2%) showed higher expression when compared to encapsulated tumors (p=0.02). APE-1 overexpression was found mainly in cases of CaExAP with lymph node metastasis (median expression = 90.3% - p=0.002) and invasive pattern (median expression = 89.9% - p=0.003), when compared to cases without metastasis and intracapsular pattern. Conclusion: This study suggests that APE-1 is deregulated in the studied tumors. The increased expression of APE-1 is associated with the absence of complete capsule in PA and it is associated with more aggressive behavior in CaExPA.

Variabilidade genética de Leishmania spp. circulantes entre seres humanos e cães e infecção de flebotomíneos em áreas endêmicas para as leishmanioses no Rio Grande do Norte

Leishmania infantum is the main etiologic agent of visceral leishmaniasis in the New World. The pattern of distribution of leishmaniasis has changed substantially and has presented an emerging profile within the periphery of the Large Urban Centers. Leishmania infection can compromise skin, mucosa and viscera. Only 10% of the individuals infected develop the disease and 90% of human infection is asymptomatic. The main factors involved in the development of the disease are the host immune response, the vector’s species and the parasite’s genetic content. The sequencing of Leishmania isolated seeks to increase the understanding of the symptoms of individuals. The aim of this study was to evaluate the genetic diversity of circulating Leishmania strains among humans, and symptomatic and asymptomatic, and dogs from endemic areas of Rio Grande do Norte State and analyze sandflies from endemic areas for cutaneous and visceral disease. The genetic variability was evaluated by the use of markers hsp70 , ITS1 and a whole genome sequencing was also carried out. The amplified hsp70 and ITS1 of samples were analyzed and assembled using a Phred / Phrap package. The dendograms were constructed using the same methodology, but adding 500 bootstraps, followed by inferences on the relationships between Leishmania variants. The sequences of the 20 Brazilian isolates were mapped to the reference genome L. infantum JPCM5, using the Bowtie2 program and the identification of 36 contigs. The information of the valid SNPs were used in the PCA. SNPs were visualized by Geneious 7.1 and IGV. The genome annotations were transferred to their respective chromosomes and displayed on Geneious. The matching sequences of all chromosomes were aligned using Mauve. The phylogenetic trees were calculated according to maximum likelihood and JTT models. Sandflies were analyzed by PCR for the identification of Leishmania infection, a blood meal source and GAPDH sand fly. As a result, hsp70 and ITS1 were not capable of identifying genetic variability among human isolates from symptomatic and asymptomatic, and dogs. The complete sequencing of the 20 Brazilian isolates revealed a strong similarity between the circulating Leishmania strains in Rio Grande do Norte. The isolates collected in the city of Natal from humans and canines remained grouped in all analyzes, suggesting that there is genotypic and geographic proximity among the isolates. The isolated samples in the 1990s had a higher genotypic diversity when compared to freshly isolated samples. All isolates presented 36 chromosomes with variable ploidy among them, no correlation was found between the number of amastina genes copies, gp63, A2 and SSG with such clinic forms. In general, we did not find correlation between symptomatic and asymptomatic clinical forms and the gene content of the Brazilian isolates of Leishmania. 34,28% of the sandflies collected in the upper west region were L. longipalpis and the main sources of blood meal were humans, dogs and chickens.

“É acompanhante ou usuária?” Implicações sobre a posição da família no atendimento a crianças e adolescentes em um Centro de Atenção Psicossocial da Infância e Adolescência - CAPSi

This study emerged and founded itself with the aim to analyze the position taken by the family – and the implications in this subjective area – in attending children and adolescents in a Childhood Psychosocial Care Center (CAPSi). A secondary goal has come up as the comprehension surrounding the institutional representation made about the family and the service offered to children, adolescents and relatives. For such, the historical perspective on the relation between the State (laws and institutions) and the family was resumed, and the understanding of how it was reconciled by the medical knowledge and attended the ideological and political means. The social and ideological transformations of the 20th century culminated in the need of change required by the Psychiatric Reform and the achievement of patients on the right to return home and to their families. This new situation, permeated by the attempt of building an assistance model in Mental Health, presented a peculiarity–the close relationship between family and Mental Health services. The observations and conversations at CAPSi that were the investigation objects in this research, intended to learn on the quotidian of families and the possible treatment alternatives that would take into account the family circumstances. Conceiving the status of the families in Mental Health services is a germinal matter yet to be adjusted among the active knowledge in the post-Reform devices. The discussion about the family bonds, anchored in the theoretical perspective of Binding Psychoanalysis brought up elementary concepts such as psychic heritage, denial pact, unconscious alliances, the familiar psychic set, among other. The concept of family organizer helped to think of the family trajectories and stablishes a sort of identity for the family, as well as interferes in the establishment of its boundaries. The family path within the institution, as well as the status they establish facing the institutional approach, reflect the ghosts and the organizers shared by the group-family. It follows that the family is an important protagonist to be considered in the current therapeutic and political processes and, thus, is key to welcome the family bonds for the alliances act over the affective destinations, as well as try to remain sealed from the proposed changes.

O ensino de arte pós-moderno na arte de Daniel Francisco de Souza

This thesis presents a research that links cultural history and visual culture in a sociobiographical approach. It gives a “political treatment” to the educational experience in the transition of art teaching from the modern to the postmodern. By taking into account my experiences as an educator and the poetic practice in Daniel Francisco de Souza���s visual art, I propose a dialogue with his art and a series of visual narratives this artist/student produced at the time of his education and recently. Such visual narratives were taken as research source and research subject. They were created in a rural setting in dialogue with formal art teaching in two phases: 1992–6, when Daniel Fran cisco attended elementary school in the rural area of Uberlândia, MG; and 2008–10, when he attended Visual Arts graduation at Federal University of Uberlândia city. I analyze historical processes related to art and teaching, from the early sixteenth century to the present times, to realize residues in students’ poetic experiences. I relate Brazilian educational public policies with experi- ences in that rural school. I try to show the extent to which our educational practices triggered experiences — from ones common to intense ones — and promoted forms of “emancipation-knowledge” or “regulation-knowledge” and how the “selective tradition” was and how art predetermined history images gave way to everyday visual references, pointing to the “broad field” of visual culture. I make an effort to show Daniel Francisco’s work as an adult by tak- ing it according to different approaches. In a poetic reading, first, I emphasixe the material and the symbolic in his art. In a second look, I approach his work through the intertwining experiences of three characters from different times and places that participated in the making of his art: the artist farmer, the artist teacher and the teacher researcher. I assume the existence of a mutual cultural incompleteness in these three characters; which means that parts of their “structures of feeling” built on the interrelationship among them are part of the artist’ work as a historical content decanted. Thirdly, I demonstrate how the artist sees his place as a key re ference to his poetic creation. His work does not reflect the rural bucolic as something untouched. In showing the difficulty in distinguishing the archaic residual, I identify emerging issues in his work. I conclude that the artist — Daniel Francisco — and the researcher — myself — present maverick features: both are scavengers; their productions approach the working with scraps in art and in the academy; even momentarily, they live in exile in the warmth of the borders or the edges, from where one sees the center clearly. In these spaces, when certain structures and normative codes enter into coalition, they fragment pre-established strategies and stimulate the creation of survival tactics.

Weaving Futures. Family Transnationalism in the migration from Dominican Republic and Brazil to Spain

This article explores forms of migrant families’ reorganization within a (new) global economic crisis and the hardening of migration control in Europe; based on the cases of Dominican and Brazilian migration to Spain.Our goal is not to characterize the wholeness of strategies from these collectives, instead visualize its heterogeneity. Displacement of Dominican and Brazilian population to Spain shares the role of women as the first link of migration chains. In both cases women are the economic support of transnational families and they lead reunification's processes. Nevertheless, differences in the time spent in the destination country, migratory status, origin (rural-urban), level of education, class and labor insertion in destination country, affect differently, the planning and start up of migration projects, the organization of care and family reunification strategies. These findings question the predominant place granted to national origin in the study of international migration.

CAREGIVING FOR A FAMILY MEMBER WITH HEAD AND NECK CANCER

Objective: To know the perception of informal caregivers regarding the care for a family member with head and neck cancer. Methods: Qualitative study conducted between March and May 2014 in the radiotherapy outpatient center of the Centro de Alta Complexidade em Oncologia – CACON (Oncology High Complexity Center) of the Hospital Universitário de Brasília – HUB (University Hospital of Brasília) using semi-structured interviews with nine caregivers about the experience of caring for family members. Data underwent Content Analysis and four units of meaning were identified: “Representation of cancer in the Family”, “The care as debt, individual reward or reconstruction of family ties”, “Repercussions of cancer on the caregiver’s personal life” and “Social support and network used by caregivers”. Results: Feelings of sadness and surprise at the moment of diagnosis were attributed to cancer, as well as the idea of punishment. The care was seen as personal satisfaction, accomplishment and opportunity for family rapprochement. Work overload and change in routine were altered functions. Religiosity, exchange of experience in the waiting room and institutional support appeared as coping strategies. Conclusion: The experience of caring for family members with head and neck cancer directly interferes in the lives of caregivers. Pointing out the institutional embracement as a strategy within the social network reinforces the importance of integrating the caregivers as a significant part of the health care plan developed by the health team.
