Mapeamento cromossômico de DNAs repetitivos com fins biotecnológicos em peixes marinhos e interesse comercial - Rachycentridae e Lutjanidae

The Rachycentron canadum species, commonly known as beijupirá or cobia is the only representative of Rachycentridae family which has been increasingly used in marine fish farming, in intensive cultivation. As advantageous features it has easy adaptation, prolific behavior, early growth in captivity and high commercial value. Additionally, specie of Lutjanidae family (Lutjanus synagris, Lutjanus jocu, Lutjanus analis, Lutjanus alexandrei and Ocyurus chrysurus) represents an important fisheries resource in all areas of its occurrence. In Brazil, the commercial exploitation of Lutjanidae which begun in the 60's and 80's, already has showed a decline in catch volumes. This fact suggests that the snappers must have a conservative management. Despite the economic potential, little is known about the genetic and cytogenetic characteristics of these species, especially with respect to repetitive DNA analysis, which represents the major part of the eukaryotes genome, playing important evolutionary roles in the fish genome. Cytogenetic data is increasingly being used in population studies and biotechnological purposes in fishes. The cytogenetical analyzes were performed using classical methods such as Giemsa staining, C-banding and Ag-NORs, fluorochromes base-specific staining (DAPI and MM) and physical mapping of repetitive sequences among which, telomeric sequences, transposons (Tol2), retrotransposons (Rex1 and Rex3), repetitive DNA (microsatellites and Cot-1) and transcriptionally active regions of the 18S and 5S ribosomal genes and histone (H3 and H2BA) by in situ hybridization with fluorescent probes (FISH). The chromosomal patterns obtained contributed to the organization of repetitive sequences in the genome of the species, as well as karyotypical differentiation. Unusual patterns of histone sequences expansion depict the first occurrence in marine fishes. The obtained data provided subsides to the genetic knowledge of the important fisheries resource represented by the species here analyzed, seeking the marine pisciculture improvement.

Uma viagem insólita: de um território pesqueiro a um paraíso turístico

O presente trabalho intitulado Uma viagem insólita: de um território pesqueiro a um paraíso turístico tem como objetivo buscar compreender e interpretar as mudanças socioespaciais que ocorreram na Praia da Pipa/RN, decorrentes da expansão da atividade turística e seus reflexos no território, no período compreendido entre os anos de 1970 e os dias atuais, recorrendo-se a fontes bibliográficas, entrevistas e observações in loco, além de levantamento de dados secundários, cartográficos e fotográficos. Reporta à nova territorialidade que emergiu com a expansão da atividade turística para o litoral norte-rio-grandense, atraída pela praia e pelo sol, que fez convergir para essa área, produtores e consumidores não apenas locais, mas também regionais, nacionais e internacionais. Do ponto de vista social, a população nativa vem sendo expropriada de seus espaços, da sua cultura, das suas tradições e, até mesmo, do mercado de trabalho, o que vem provocando um processo de desterritorialização e o surgimento de novas territorialidades marcadas pela atividade turística. A expansão da atividade turística em Pipa/RN, a partir de 1970, tem provocado um processo de construção de um novo território o território turístico que se reflete dialeticamente através do surgimento de um novo cenário socioespacial constituído de formas e imagens expressas materialmente no lugar

Ambiente pesqueiro e saúde: representações sociais sobre saúde e doença de pescadores e marisqueiras nos distritos de Diogo Lopes, Barreiras e Sertãozinho Macau RN

According to Brazil s Ministry of Fisheries and Aquaculture, artisanal fishermen are responsible for a significant fish production at national level, highlighting the importance of this activity. In Rio Grande do Norte State, Brazil, fishing has become an important part of economic and social processes. In this context, there are many inland fishing communities such as Barreiras, Diogo Lopes and Sertãozinho, which are part of Ponta do Tubarão State Reserve of Sustainable Development (RDSEPT), located in Macau and Guamaré, Rio Grande do Norte coastline cities. Fishermen and women, the last ones known as marisqueiras who work alongside the menfolk at sea, especially in the shellfish harvest, have been developing narrow relationships with nature, mainly with the sea, from where they extract their families subsistence. However, those communities have been facing several issues related to living conditions, health and diseases. Social representations have been analyzed in the speeches of fishermen/women who were registered active members in a fishermen association named Associação Colônia de Pescadores Z-41, regarding the period from 2008 to 2011. The analysis involved socio-economic profiles verification, identification and analysis of the group s main representative diseases and representations related to health and illness. This study searched for elements in order to provide the comprehension of the relationships among people s social representations and the fishing environment in which they live.. This qualiquantitative study was performed using recordings and transcriptions of structured and open-question interviews. The Collective Subject Speech tecnique proposed by Lefevre & Lefevre (2002) was applied to perform the interviews analysis using QualiQuantiSoft® software. The results showed that health and illness phenomena as well as social representations related to them in the fishing environment are not only abstract states but also physical ones, which interfere in all life extensions, establishing a set of relevant information that indicates that those people realize their own socio-cultural, economic, environmental and political context

Design de interfaces para aplicativo de smartphone como recurso auxiliar no acompanhamento clínico de pacientes fibromiálgicos

Este trabalho tem como objetivo o desenvolvimento de interfaces com o usuário para aplicativo móvel smartphones com intuito de contribuir para a eficiência das atividades de profissionais e pesquisadores da área de fisioterapia ao oferecer suporte ao acompanhamento clínico da dor no tratamento de pacientes fibromiálgicos. Utilizando a abordagem de Design Centrado no Usuário - DCU, foram realizadas entrevistas e uma investigação contextual para a identificação inicial dos problemas e necessidades dos usuários. Verificou-se que as atividades de monitoramento e acompanhamento das sessões do tratamento de pacientes fibromiálgicos são, tradicionalmente, realizadas por meio de manipulando de formulários e fichas em papel (registro das condições de saúde do paciente) e escalas de classificação da dor em formato impresso (apresentadas ao paciente para indicação de sua dor percebida para cada ponto pré-determinado do corpo). Os procedimentos envolvidos nestas atividades dificultam o gerenciamento do desempenho do tratamento, o que, segundo relatos, reflete no comprometimento dos pacientes na adesão e frequência as sessões. A partir da observação e do levantamento das necessidades desses profissionais diante de suas atividades, foi proposto um aplicativo para smartphone com a intenção de minimizar os problemas ocasionados pelo uso das ferramentas convencionais e de prover informações rápidas acerca dos dados coletados. Então, seguindo a abordagem do DCU foi elaborado um modelo conceitual durante a etapa de concepção de soluções, o qual guiou a criação dos protótipos. A avaliação das interfaces do protótipo foi realizada com o envolvimento dos usuários a partir da técnica de avaliação cooperativa. Seus resultados proporcionaram o refinamento das interfaces e o desenvolvimento de uma nova proposta do design das interfaces em protótipo de alta fidelidade, produzido para o ambiente Android. Assim, esse trabalho faz parte do processo de desenvolvimento de um produto de software personalizado com foco na concepção e avaliação das interfaces com o usuário. Por meio da metodologia aplicada, observaram-se indícios os quais sugerem que as interfaces propostas apresentaram-se como um recurso facilitador e capaz de contribuir para eficiência das atividades no acompanhamento do tratamento de pacientes fibromiálgicos

A tabela periódica: um recurso para a inclusão de alunos deficientes visuais nas aulas de química

Nowadays there are many reasons that aim to include people with special necessities, like those with visual deficiency, in the world of work, education, and in the society as a whole. However it is observed that when we talk about schooling inclusion, especially in High School, there is a huge gap between the theory and the practice. The lack of didactic resources, the inadequate installations, unprepared teachers, the families´ lack of information, are some of the factors that hinder the process of inclusion. Furthermore, the educators also have to deal with the roughness of the disciplinary contents and, refering to the study of Chemistry, with the use of signals related to this subject´s language. So, the objective of our research is to reflect about the apprehension of this language by the visually handicapped people, and try to contribute with their process of inclusion in the school life. On this perspective we work with the Periodic Table, which constitutes one of the indispensable tools necessary to the Chemistry learning. In order to acomplish it, the way followed by us happened in three passages. Initially, by means of a semistructured interview, we tried to get acquainted with the blind students opinion, who were participating in the research about the Periodic Table used by them throughout High School, as well as the dificulties felt when using it. After getting the answers, the Table was reelaborated to fill those students´necessities. Here, two new Tables were designed, one in Braille which shape is more compacted, and another made with high printed dots, built with sand and glue. On the third moment, the new designed Tables were tested by the students and, by means of a semi-structured interview, we tried to identify if this new resource would solve the problems concerned to the old Table. The students showed that the compacted Tables would facilitate the touch reading of the chemical elements simbols, making it clear and fast. We hope that, with the elaboration of this learning tools we can contribute with one of the elements to favor the effective participation of blind students in Chemistry classes, when studying the Periodic Table

A Informática como recurso didático para a aprendizagem de Física no ensino médio

The accomplishment of this work was motivated by our concerns, while teacher of Physics discipline, in the medium teaching and in the higher education, where we have been observing a lot of difficulties in the students' acting, to the they try to give pursuit out to their studies of the classroom, because of the lack of appropriate equipments, or even, of a laboratory where they can put in practice the studied contents. The work aims at to build and to test an educational software that it serves as tool auxiliadora in Physics learning in the Medium Teaching, in the area of electricity, with emphasis in the study of the electrodynamic in resistors. The developed software comes as an alternative to the learning problems, putting the computer science as auxiliary tool, because, besides being an alternative in the middle of the technological expansion, endowed with several resources, it stimulates the significant learning, according to David Ausubel's perspective. A software containing a program destined to the applicability of physics contents in the branch of the electricity is presented as an auxiliary tool, where the student can, not just, to review the contents presented at room, as well as for in practice, through a virtual laboratory, some of these contents, besides testing their knowledge through a bank of discursive subjects. The evaluation of the developed software was made submitting him/it to the professionals' of physics area appreciation. Equally, through continuous evaluations, they were made comparisons among the students' of five different groups acting, in the same school, that you/they were used of the program as tool of his auxiliary learning, and the acting of those that didn't use it

Transferência de alimento aos infantes de Callithrix jacchus em uma situação de escassez de recurso alimentar

The genus Callithrix, like other marmosets, presents a cooperative breeding system, characterized by the contribution of parents and non-breeding individuals of the social group in the care of infants. This care is provided through lactation, transport, supervision of infants and food transfers. In this study, we investigated the care of offspring in Callithrix jacchus through the food transfers in family groups under conditions of abundance and scarcity of food resources. We also attempted to verify the relationship between the participation of individuals in the transport of infants and in the food sharing. We observed four families at the Núcleo de Primatologia of the Universidade Federal do Rio Grande do Norte, in a total of seven infants, six twins and a single infant. Each infant was observed twice a week, from 1st to 20th week of life using the methods focal continuous and focal instantaneous sampling with one minute intervals. The observations were carried by 10 minutes and beginning with the supply of food for each family. Two families were tested under conditions of scarcity of food resources (experimental condition) and two others were subjected to conditions of abundant food, both conditions with restricted access to food supply. The condition of food scarcity did not influence the rate of food sharing with the infants that, in general, was considered low. All shares observed were passive sharings. Only one family showed higher levels of food begging, probably due to the loss of the mother during the period of lactation of her offspring. In this family, the dominant and subadult males were primarily responsible for the food sharing. The experimental condition influenced the distance of infants in relation to food source, so the infants in families that received abundant food remained closer to the source. However, it is believed that the place of food consumption was not influenced by experimental condition. There was no relationship between the participation of individuals in the transport and food sharing with their young. Therefore, it is suggested that, in general, the transfer of food in C. jacchus is characterized by tolerance to the demands of caregivers, represented by the passive sharing. Rates of sharing with infants were low, probably due to intra-group competition for food generated by the experiment.

Ativos intangíveis (modelo RBV) como recurso estratégico e competitivo: um estudo em hotéis de pequeno porte (zona sul, Natal/RN)

The study aims to analyze the perception of managers on intangible assets as strategic and competitive resources in small hotels in Natal/RN, through the theory of the Resource Based View (RBV). This is a qualitative study of exploratory and descriptive, conducted with managers of the means of hosting small the capital of Rio Grande do Norte through semi-structured interviews, which was applied later, the technique content analysis based on the results of the information obtained in the interviews. Thus, research has shown that managers of small hotels visited (A, B, C) are not sufficient and satisfactory knowledge to set as their unique intangible assets of the company and makes use of them, on an occasional basis, without understanding or in essence understand its true value as a resource that can be used strategically for sustainable competitive advantage in the hotel market in Natal/RN. This means that managers do not know how to create new attributes and use them strategically. And they need to expand their partnerships with stakeholders. Given the importance of the subject of the present research, the information achieved by this analysis may contribute to the provision of information to establish a current situation with regard to the attributed to the knowledge and use of resources (intangible assets) importance as a strategic source and competitive for the internal management of the company by managers and thus, enabling a differential and greater economic profit over time in this segment
