Influência do tipo de abrigo e da frequência de oferta alimentar no comportamento do camarão Macrobrachium rosenbergii (De Man 1879)

Macrobrachium rosenbergii is a freshwater prawn which presents agonistic behavior and heterogeneous growth. It is known that captive conditions can intensify agonism causing injuries and decreased survival, generating a condition of poor welfare. Based on this, we aim to investigate the behavior of M. rosenbergii in the juvenile phase according to different types of shelter and frequencies of feed offer, emphasizing their agonistic behavior. For this, juveniles were observed in the laboratory in three steps. At step I we characterized the behavioral profile; prawns were kept in eight aquariums (27 prawns/m2 ), identified and observed four times along both phases of 24 h light cycle. At step II (2 experiments), we evaluated the use of shelters (brick or polyethylene rolls) and their influence on agonism by the animals. For classification of animals in dominance rank, the method used was David's Score. At step III (3 experiments), we evaluated different frequencies of feed offer on the behavior of individuals, in particular agonism. Results showed that juveniles do not present a pattern activity/inactivity between the phases of the light cycle. We identified a dominance hierarchy among individuals taking advantage of access to food by the dominant, which showed greater weight gain although the frequency of intake did not differ between individuals. The type of shelter influenced the behavior of animals. Brick shelter generated a higher frequency of permanence and a reduction in the frequency of agonistic interactions. The distribution of food more frequently throughout the day, decreased the motivation of animals for food, as well as to fight. Prawns fed four times showed lower frequency of feed intake and agonistic interactions. Thus, we conclude the shelters which reduce animal’s detection by coespecifics and offer the food four times along the day reduce agonistic behavior. This result causes na improvement in life quality of the prawns and also in its quality as final product.

Gestão de recursos hídricos: governança e gerenciamento de conflitos pelo uso da água em região do Semiárido Nordestino

The water being vital natural resource and factor of economic and social development requires effective management and protection by the State. This thesis examines the panorama of National Water Resources Policy and the establishment of an effectively integrated management, shared and participative, contextualizing the principles foreseen in the policy. The work is focused on the discussion of public policies of access to water, analyzing the Fresh Water Program in semi-arid region of Brazil as a strategy of coexistence and permanence of a public policy that ensures the priority use, which is for human consumption. The conceptual framework of this study relies primarily on the contributions of authors in the field recognized as governance and water management. A study on the process of implementation of the various "institutions and policies" related to water management was promoted, contextualizing the change of paradigm in the transition from the centralized model to the one that takes into account the social participation, opening in this way broader perspectives for the analysis of the contents and of the impacts of these policies. The development of this study was conducted by the follow-up – both face-to-face as documentary-field – of the activities carried out while consultant of the Fresh Water Program. The history of water management in the semi-arid region was studied, depicting conflict movements and cooperation among actors. Despite the great obstacles to accomplish the shared and decentralized management, the study of this thesis points to a gradual improvement in the formulation of public policies that take into consideration governance and participatory management of water resources, with positive prospects towards the implementation of coordinated and cooperative actions in the region that mainly suffers from the shortage of rainfall, hence of shortage of water for irrigation and human consumption

Inclusão de estudantes com deficiência no Instituto Federal da Paraíba a partir da ação TEC NEP

The current research developed in the Federal Institute of Paraíba – IFPB, João Pessoa Câmpus, aimed at analyzing the inclusion of students with disabilities in undergraduate courses based on the TEC NEP Action. It departs from the discussion about professional and special education in an inclusive perspective, focusing on people with disabilities, in the social context of these two modalities of education, considering the world scenario and the current Brazilian educational policy. It discusses the TEC NEP Action within the national and local context through the analysis of the official documents with the objective of getting familiarized and evaluating the process of educational inclusion in the IFPB João Pessoa Câmpus. The theoretical reference used contributed to the analysis of the policy which focused on inclusion in federal undergraduate institutions for professional education. The methodology used presents a qualitative analysis, having as subject of the research students with disabilities from undergraduate courses in the IFPB João Pessoa Câmpus who are supported by NAPNE. The results based on the analyzed data show that volunteer students from this research evaluate their process of inclusion in the appointed institution as positive, in spite of challenges specially the ones related to architectural barriers. It is concluded that the foundation of the House for Supporting People with Special Education Needs – (NAPNE) through the TEC NEP Action had crucial importance in the basis for the discussion about inclusion in the institution, widening the vision towards the demands of students with disabilities in order to facilitate access, permanence and academic success of these students.

As necessidades formativas de professores para o trabalho com a educação integral

In Brazil, since the 1990, the country has been operating an extensive transformation in the education system. This situation is justified, among other reasons, the search for answers to the new demands that modern society gives to school, to new technologies and information and communication systems. To better put the Brazilian school that context, the federal government, through the Ministerial Decree No. 17/2007, created the More Education Program as a measure to combat low levels of development of basic education in the capital cities and metropolitan areas, aiming at the implementation of comprehensive education in schools. After the first year since the implementation of the program, there are advances in the permanence of students within the school. But as for the teachers, there is a gap on ownership and consequent acceptance. Considering the reality of the state system of schools of Basic Education in Natal - RN, this study investigates the training needs of teachers in institutions working with More Education Program, envisioning the educational relationship with Macrocampos contained in this national project. Answering this question allows us to absorb the concept of such needs in teachers, as well as to check priority in relation to the continuing education of teachers for this new pedagogical reality.

Desempenho zootécnico dos camarões: Litopenaeus vannamei e Macrobrachium rosenbergii em tanques rede e aquicultura familiar na comunidade de Bebida-Velha, RN

The study aims to evaluate the performance and identify lesions of agonistic interactions of Macrobrachium rosenbergii in different densities cages (chapter 1); compare the growth performance of shrimp M. rosenbergii and Litopenaus vannamei cages (chatper 2); in addition the study aimed at identifying the knowledge and practices of a traditional community of farmers Bebida-Velha, in the city of Pureza / RN, practicing rural family and aquaculture, as well as tracing the community socioeconomic profile and evaluate the management that these farmers use in shrimp farming Macrobrachium rosenbergii (chapter 3). To perform the experiments (chapter 1 and 2) shrimp species L. vannamei and M. rosenbergii were weighed on a digital scale and transferred to cultures in cages. The cages had 1m³, with 5mm mesh between us and were closed on top with screen to avoid predators (birds, insects). The animals remained in adaptation for fifteen days before the start of data collection (each experiment). Both experiments lasted seventy days, totaling eighty-five days cultivation. During the cultures, animals were fed pelleted feed for shrimp at 10% of their biomass with 35% crude protein, offered in feed trays twice a day during the hours (7:00 am and 14:00 pm). The remnants in the tray were removed after 2h of permanence to calculate intake. To determine the performance parameters, some samples were taken every 10 days. The results of both experiments were analyzed using the STATISTIC 7.0 (2004). In Chapter 1 experiment were applied5 treatments were applied with 5 replications each: D5 - 5 animals/m2 ; D10 - 10 animals/m2 ; D15 - 15 animals/m2 ; D20 - 20 animals/m2 ; D25 - 25 animals/m2 . To this, were distributed 25 cages randomly in two masonry nurseries. The end of the experiment the lesions were verified and quantified. The chapter 2 experiment began when the shrimp reached the same age (eighty-four days) and was used the density of 25 shrimp / m2 with 4 repetitions. For the realization of chapter 3 were applied semi-structured interviews by direct approach of Bebida Velha of settlers practicing aquaculture activity, tilapia producers and community shrimp. Data were tabulated and analyzed according to the responses obtained by the participants. Therefore, the amount of damage increased with increasing stocking density. The density of 10 freshwater shrimp/m² showed the best conditions for a better performance in cages. It can be concluded that in cages, the cultivation of species of fresh water shrimp M. rosenbergii had better zootechnical indexes than the cultivation of marine shrimp species L. 9 vannamei. It was possible to verify that the activities of which the interviewees practice guarantee a good quality of life and income for them. We find that respondents have traditional and local knowledge, and also may be interested in the cultivation of the species M. rosenbergii.

Educação profissional e tecnológica de turismo no Brasil: análise através da percepção de docentes da rede federal de educação

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.

Núcleos de acessibilidade e o atendimento a alunos com necessidades educacionais especiais nas universidades federais do nordeste brasileiro

In the current context of policies for inclusiveness in the Brazilian higher education, the accessibility centers are responsible for the organization of actions toward the fulfillment of the legal requirements regarding accessibility and the elimination of barriers that interfere with the participation and learning of persons with special learning needs (SLN), providing conditions for the full inclusion of these students in the activities of learning, research and community outreach in this learning level. This research had the goal to analyse the work developed by the accessibility centers in the federal universities in the northeastern region of Brazil towards the care of students with SLN. It is a descriptive work, with quantitative and qualitative approaches. Twelve federal universities participated through their accessibility center’s coordinators. The data - gathered by means of an electronic survey filled out in 2014 - was organized and analyzed through descriptive statistics and content analysis; their discussion was made around four topics: organization of accessibility centers for the care of students with SLN, kinds and numbers of students with SLN cared for, actions developed, and suggestions for the improvement of the accessibility centers. It was found that in the sphere of the researched universities, the accessibility centers have been taking actions involving many parts of the academic community towards the improvement of the conditions and permanence of students with SLN. However, in some institutional realities, these action need to be expanded and/or consolidated. The coordinators suggest further actions towards the betterment of these centers, regarding expansion of financial and human resources, professional qualification, awareness of the academic community, institutionalization and the formation of a collaborative network among the accessibility centers. Thus, although there are still challenges to overcome, the presence of the accessibility centers is shown to advance the realization of policies for the inclusion of students with SLN in the post-secondary education, towards the democratization of learning starting from the universal right to education.

Remoção de fenol de efluentes aquosos utilizando floculação iônica

Oil exploration is one of the most important industrial activities of modern society. Despite its derivatives present numerous applications in industrial processes, there are many undesirable by-products during this process, one of them is water separated from oil, called water production, it is constituted by pollutants difficult to degrade. In addition, the high volume of generated water makes its treatment a major problem for oil industries. Among the major contaminants of such effluents are phenol and its derivatives, substances of difficult natural degradation, which due their toxicity must be removed by a treatment process before its final disposal. In order to facilitate the removal of phenol in wastedwater from oil industry, it was developed an extraction system by ionic flocculation with surfactant. The ionic flocculation relies on the reaction of carboxylate surfactant and calcium íons, yielding in an insoluble surfactant that under stirring, aggregates forming floc capable of attracting the organic matter by adsorption. In this work was used base soap as ionic surfactant in the flocculation process and evaluated phenol removal efficiency in relation to the following parameters: surfactant concentration, phenol, calcium and electrolytes, stirring speed, contact time, temperature and pH. The flocculation of the surfactant occurred in the effluent (initial phenol concentration = 100 ppm) reaching 65% of phenol removal to concentrations of 1300 ppm and calcium of 1000 ppm, respectively, at T = 35 °C, pH = 9.7, stirring rate = 100 rpm and contact time of 5 minutes. The permanence of the flocs in an aqueous medium promotes desorption of the phenol from the flake surface to the solution, reaching 90% of desorption at a time of 150 minutes, and the study of desorption kinetics showed that Lagergren model of pseudo-first order was adequate to describe the phenol desorption. These results shows that the process may configure a new alternative of treatment in regard the removal of phenol of aqueous effluent of oil industry.

O ensino por investigação: construindo possibilidades na formação continuada do professor de ciências a partir da ação-reflexão

Studies and reflections about the current trends on teaching Science show us the importance of include in the teaching practice, activities with a investigative and problematic approach, that allow to the learners to understand and to apply concepts and phenomena scientifics. On this perspective, the teacher continuing education is essential to effect the practice of this approach in the classroom. Therefore, this research has as an objective to contribute with Science teacher continuing formation in the basic education, in the use of the investigative approach, with a view to overcoming obstacles and making change in pedagogical practice using this research elements. For this, a qualitative research with science teachers of basic schools in the city of Natal/ RN/ Brazil was held, who attended the training course on teaching by investigation in 2012, through the project entitled "Em Busca de Novos Talentos para a Ciência: uma intervenção no ensino público" (Searching New Talents for Science: an intervention in public education).The research was conducted in four stages: Diagnosis of the conceptions of education for research and incorporation into practice after the New Talents course; projection of the intervention, intervention and evaluation. To obtain the data it was made a questionnaire, semi-structured interviews, group studies, written records and participant observation. It was analyzed that the course had significant contributions to the participating teachers to promote the approach and the motivation for incorporation of the investigative approach in practice. The permanence of weaknesses related to the theoretical basis was found, the wear resistance, difficulty in planning activities and the change in practice, diagnosed the previous course of this research. It was also noticed certain lack of domain of teaching principles of investigation by the teachers, who despite being well understood in theory, reveal gaps in practice. Despite not having been exploited the full potential of investigative activity is apparent that the inclusion of activities with an investigative approach to science and biology classes is essential for an active, critical and reflective posture of the students as well as the interest in learning about science. It was demonstrated that intervention with moments of reflection, engagement, knowledge exchange, it was effective in overcoming difficulties identified at baseline as well as providing greater motivation to face the innovations and changes in education, suggesting an important format to considered in the course of continuing education. This is because the planning and replanning allow teachers to reflect and evaluate their practice, contributing to overcoming difficulties of teachers on a daily basis.

As raízes históricas da política criminal na legislação e nas práticas de atendimento ao adolescente em conflito com a lei

This thesis investigates the historical influence of the criminal policy in the context that shapes the first specific law for children and adolescents in Brazil, the 1927 Children's Code, a standard that inaugurates the conceptual scission between children and "minor" and their different treatment by the State. The study addresses the demand for order in the context of changes in the working world in the transition from the slave system to the capitalist mode of production, and the corresponding disciplinary and punitive control mechanisms directed to the segment of childhood and adolescence. The theoretical route proposes a questioning of the political construction of law and justice, as well as the conformation of the punitive techniques, and the construction of the stereotype of the "delinquent", prime target of the criminal policy, focusing on the process of criminalization of the segment in question through the confrontation of the Critical perspective with the approaches of Classical and Positive schools. This research shows the imposition of a bourgeois morality that obscures the social conflict attributing it to people isolated by the criminalization of their conduct; and points out that the historical forms of selective social control were greatly influenced by psychiatry and psychology, either by the elaboration of the image of the "delinquent" or by the expected performance of custodial institutions. Finally, the developments and the permanence of the historical roots of the criminal policy are problematized, relating them to the difficulties currently encountered in the consolidation of the legal garantism paradigm proposed by the Children and Adolescent Statute.

Quem é o doente? Um estudo sobre as vivências dos acompanhantes de pacientes adultos em hospital público no Rio Grande do Norte

The aim of this research is to reveal how caregivers have lived the experiences from adult patients admitted in a Rio Grande do Norte’s state hospital. This is a study where the use of the participant observation, associated with the use of interviews and informal conversations handled categories such as the mismatch between the prerogatives of Brazilian Health Care Policies (HumanizaSUS) and practices performed in hospitals, the relationships established between the caregivers and the other subjects of the research field, family relationships, permanence of women as caregivers, therapeutic itineraries, dramas, religiosity and secrets. To sew up it appears the role of a caregiver is more than emotional support or help, it is a complex act in several directions.
