Metodologia para avaliação do tempo de cozimento e características tecnológicas associadas em diferentes cultivares de mandioca

O consumo culinário de raízes de mandioca é bastante generalizado em todo o mundo, sendo essa raiz amplamente utilizada na forma cozida, assada, frita ou integrando pratos mais complexos. O objetivo deste trabalho foi definir metodologia, avaliar o tempo de cozimento e algumas características associadas a este processo em 26 cultivares de mandiocas. Avaliaram-se os seguintes parâmetros avaliados foram cor da entrecasca; cor da polpa; dificuldade de soltar a entrecasca; dificuldade de palitar; porcentagem de água absorvida/perdida em relação ao peso dos toletes durante o processo de cozimento; cor dos toletes cozidos; formações de pontuações brancas no interior do tolete; formação de gel em volta dos toletes e tempo de cozimento observado para cozimento de 13 palitos. Ao final da avaliação concluiu-se que as melhores cultivares para utilização como mandioca de mesa foram a SRT-1105 (Mico), Milagrosa RG, Mantiqueira, IAC 522-30, IAC 576-70, sendo a última a que apresentou melhor resultado no teste de cozimento.

O incesto : discurso e ideologia

This research had as purpose to establish the logic symbolic present in the contemporary society that facilitated the emergency of a public speech on the incest, and, consequently, to demonstrate the ideological nature that structures it. Event associated to the order of the taboo, the incest would be the transgression of the injunction that, second Lévi-Strauss, facilitated the emergency of the Culture while symbolic order, differentiated of the natural order. The injunction of the incest would reveal the elementary and universal structures of the order symbolic presents in the human societies: the demand of the Rule as rule; the reciprocity and the gift, present element in the social changes that it transforms the individuals in partners, increasing a new quality in the transferred value, according to Lévi-Strauss. Starting from this, I developed the hypothesis second which the phenomenon of the alone incest became an event of discursive order and public as right social transformations affected the normative system (social representations, values, moral) regulator of the relationships among the social subjects, being reflected like this, in the own structuring of the Law. A second work hypothesis was developed starting from that. I develop it leaving of the argument that if when inserting the discussion of the thematic of the defense of the children and adolescent rights, being then, considering it while "privileged modality of sexual abuse against children", the present central subjects in the structuring of the social entail would be leaved. Being like this, the partner-institutional speech on the incest would answer the social demands of order and social control, becoming like this, discursive formations of ideological character. This research work tried to follow the hypothesis above referred, demonstrating the singular sense that it will be attributed to the incest in the contemporary society, particularly, its relationship with the Law and the transgression in the contemporary society

O princípio constitucional da eficiência aplicado à outorga e à cobrança da água produzida na exploração petrolífera

Water production is unavoidable during a petrol well s lifetime. The amount of produced water associated with oil varies a lot. It can reach values which account to 50% in volume up to nearly 100%, at the end of the well s economic life. It could be verified that, once the water reaches the productive wells, there must be a management of this produced water. Its destiny is defined after a precise study, after which the best option is chosen between relieving it into the environment, re-injecting it into the producing container or disposing it into non-producing formations. Whichever option is made by the involved professionals, after the necessary analysis, it shall consider, besides the technical and economical aspects, also the alternatives which entail less environmental impact. The purpose of the present research is to conduct a study about the application of the constitutional principle of efficiency on the instruments worked out by the public administration on water management, specifically the water use licence and charging for the use in the management of water resources applicable to water production at the petrol wells. In this attempt, before entering the proper approach of the efficiency of the mentioned instruments, it was necessary not only bring to light the doctrinal perception about the constitutional principle of administrative efficiency, but also make some considerations concerning to the structure of the national water resources management, set by the Federal Constitution (1988) and the federal legislation (9433/97)

Ensinar/Aprender ortografia: uma experiência na formação de professores

The studies in the education area have been defending the importance of forming autonomous teachers that they look for to understand the context in that they act, for that movement to make possible educational interventions with better conditions of the students' learning. In the extent of the teachers' formation, it has been discussed the importance of formative actions that they have as focus the analysis of the needs in the educational formation, as alternative to turn such more significant actions. Concerned with those subjects and with the school failure in the Brazilian education, especially in the children's of the public school literacy, we accomplished this work that aims at to investigate the needs of teachers' of the Fundamental Teaching of the public school formation, in the extent of their students' orthographic difficulties, building with those teachers knowledge on the process of teaching/learning spelling. The study was accomplished at a municipal school of the city of Parnamirim-RN, that offers the Fundamental Teaching I. the approach investigativa is of qualitative nature, where the case study and the research-action were used as methodologies. They participated in the research 7 teachers and 1 coordinator of the institution. For the construction of the data the following instruments were used: glimpsed semi-directing collective and individual, documental analysis, questionnaire and observation, that made possible the triangulation of the data for the content analysis. The main results pointed that the teachers' of that school initial needs were addressed not only to the teaching of the spelling, but also to the formation type that they would receive. We verified although the formative process was favorecedor of sockets of the teachers' conscience: related to the orthographic mistakes, to the strategies used at classroom and to the planning addressed to the teaching of the spelling. Finally, we concluded that the teachers' reflection researched about their own formation needs contributed for (trans)formations of their conceptions and practices related to the teaching of the spelling, even before some found difficulties, so much in the formation as in practice pedagogic developed by the participants

A Inclusão da pessoa com deficiência visual na UFRN: a percepção dos acadêmicos

A partir des deux dernières décénnies, des changements importants ont touché l éducation des personnes aux besoins éducatifs spéciaux. On est dans une quête permanente de leur inclusion dans les différents niveaux de l enseignement régulier. De ce fait, les institutions éducationnelles se confrontent avec le défi du changement, devant s adapter de plus en plus aux besoins de ces élèves et devenir plus récptives à l égard de tous. Malgré la lenteur de ce changement, cela favorise beaucoup l accès des élèves à des niveaux d enseignement que jamais on aurait supposés, tels que l enseignement supérieur. C est bien dans ce contexte qu au cours de l année 2002 des étudiants handicapés visuels ont accédé aux formations de Philosophie, Economie et Sciences Sociales de l Université Fédérale do Rio Grande do Norte. Cela nous a motivé à conduire une analyse, au cours de 2003, pour connaître de plus près ce processus d inclusion universitaires de trois étudiants handicapés visuels. Comme méthode nous avons utilisé l étude de cas, et l entretien comme instrument de collecte des données. Après l analyse, les résultats montrent bien que l inclusion a permis à ces étudiants de surmonter un tas de barrières, telles que l examen d accès à l Université (Vestibular), outre la chance de se socialiser et d être bénéficiaires d expériences qui, suscités dans un milieu universitaire, vont au-delà de l univers académique. Les collègues de ces étudiants, auprès desquels ils convivent, eux-aussi ont été les bénéficiaires, du fait qu ils ont eu l opportunité d apprendre ensemble les uns avec les autres, tout en respectant leur limitations et potentialités, mais en les appuyant et en les stimulant de mieux en mieux. Il faut reconnaître que plusieurs actions au sein de l Université envisageant l accès et la permanence de ces étudiants ont été couronnées de succès, mais force est de dire qu il y a aussi beaucoup de choses à faire en ce qui concerne : la préparation du corps enseignant et des fonctionnaires ; l orientation de la communauté plus élargie ; la chute des barrières pédagogiques et attitudinales, et surtout l appui humain et matériel indispensables au plein développement de ces étudiants

Tear identitário:a prática docente em arte como conhecimento compartilhado

This investigative tissue is about the formation of identification processes of teachers and pedagogical practice of Art, in Teresina city. This search comprised the sum of the needs presented, agreed upon with the teachers engaged in the process, it was developed through the establishment of interactive environment Loom Team where collaboration and critical reflection were steering actions to promote the understanding of existing connections or relations within the processes of identifications and the pedagogical practice of Art. The tissue is formed by the polyphonic plot of the critical reflection of nine teachers of Art who engaged voluntarily and this investigation of formative nature and a production of knowledge. All these teachers have degree and the course of artistic education and especial qualification in Fine Arts and/or Drawing. The texture, which we denominated Identification Loom: The pedagogical practice of Art as share knowledge is (de) (re) construction of knowledge resulting from the critical reflection, in an environment of collaboration, which may have implications and ethical political attitudes in the pedagogical practice of the group. Within this context, we pose the following question: - How does the pedagogical practice in Art influence and/or be influenced by the identification processes of the teachers, and how do they interfere with the search and manifestation of the knowledge involved and the investment in professionalization? In view of this query, we make use of the cooperative investigation, having social history as theoretical reference and as analytic perspective of interactive and dialogical-reflexive processes. Thus, social historic theory, cooperative approach and pedagogical practice were the major components of the plot. The methodological texture counted on the threads of dialogical reflexion, of mediation and of collaboration. The conceptual formulation, the recording in videos of classes and the narratives of formations were the main threads of the analytic substrate of the investigation. With this articulation, theses threads appear as developers of processes leading to a major approximation of the thought on the identity/alterity dialectical pair of the participants involved. The language within this plot had a decisive importance in all the moments of the search of signification, embracing and connecting the identification/alterative processes, the pedagogical practice of Art and the knowledge shared. In such processes involving (de) (re) construction, one can notice a close correlation of the triad social identity, pedagogical practice and knowledge shared. For this reason, the vigotskian, guetmanovian and kopnian theoretizations were the major framework for the analysis of conceptual formulations; and, as for discourse analysis, Baktin and Orlandi were our masters. For these teachers, the experience shared throughout the process of this typology of tri-axial investigation focused the experience of many theoretical and practical assumptions. Such an experience enabled them to state that this, with collaboration, can make reflection on the practice a starting and promoting element, within the individual level of self-management, in addition to being a space of (de)(re)construction of meanings, of knowledge and of reinvention per se

Prática pedagógica interdisciplinar na escola fundamental: sentidos atribuídos pelas professoras

Ce travail s'inscrit dans le cadre du débat autour de l'organisation du corps enseignant dans l'Enseignement Fondamental. Son objectif est de couvrir les limites et possibilités de la mise en application de la pratique interdisciplinaire dans les cycles I et II de l'enseignement fondamental à partir des sens attribués, par les enseignantes, à la pratique interdisciplinaire développée par elles mêmes, à leur école. L'étude défend la pratique interdisciplinaire non pas comme étant descriptive mais construite dans le vrai contexte de l'école. La méthodologie utilisée est basée sur les principes théorico-méthodologique de l'entretien compréhensif et de l'analyse de contenu. Parmi les principaux résultats de l'enquête, ressortent les limites pour la pratique de l'interdisciplinarité, situées dans le champ théorique en ce qui concerne l‟incertitude théorique sur le terme et sur le non-accès à des théoriciens qui puissent discuter la question et sur le champ de l'organisation du travail pédagogique, qui ne prévoit pas d'espace de travail collectif entre professeurs des différents terrains de la connaissance. Les possibilités proportionnées par la pratique interdisciplinaire se trouvent dans sons importance pour élargir la vision de monde du professeur et de l'élève, dans son potentiel de formation continue, pour motiver la quête à des nouvelles connaissances, des nouvelles formations pour l'élève et professeurs pour qu'ils agissent auprès des difficultés de manière plus compétente et critique. Il signale la nécessité d'un besoin institutionnel en ce qui concerne la formation continue des enseignants et l'organisation de l'espace/temps de l'école de façon à motiver les professionnels à la recherche et à la consolidation de connaissances autour de l'interdisciplinarité et des multiples champs de la connaissance ainsi que le travail collectif

Itinerários e marcas na formação do sujeito formador: reflexões acerca de um caminho na educação matemática

This Study inserts in Mathematical Education & Education that search to investigate the (self) formation of formers that gets graduation e pass to graduate others that get graduation and are formers in Mathematical Education. This Is a qualitative search in a perspective from search-formation.The work is formed of four topics. First topic talks about : The self-formation of formers. Second topic: at way of suppositions theorical-methodological from search. Third topic tells over: The life of a former life. Fouth topic A Station called Ubiratan D´Ambrosio created in his reverence and for build all the Knowledge´s Corpus developed by his studies and searches. It´s in sense of come and go from knowledge created at action by mankind to get finality of Transcendency and Survive. Look for to investigate aspects of academical, professional and personal life where are translated in language, thinking and practices oriented for one know-how holistical and transdiciplined in a reflexion, search and the critical it constitute to be a Professor, Teacher, Searcher and Etnomathematic that confered him the merit in 2005 the Prize Félix Klein, that declared Valente (2007), maximum distinction that can receive someone from Mathematical Education. The results point that the narratives of life´s stories are prominences to one re-direction of teach practical in formation´s courses of Mathematical teachers, opening spaces for what the teachers and particularly of Mathematical thinking and take position about your process of formation to be Formers. The Study also given possibilities to propose fourteen stoppages in Station that are beginnings with direction that emerge from studies and searches about the trajectory of life of Professor Ubiratan D´Ambrosio in perspective of re-signify the formative process in education and Mathematical Education

Trajetória profissional e rupturas epistemológicas na educação física e na atuação do professor

This dissertation is the result of concerns with the theoretical-methodological and pedagogical learning processes occurred in the practice of physical education in school, which accompany me since the initial training, when I experienced learning in a piecemeal fashion, focused on technicality and sportivization. In order to better qualify the pedagogical interventions of physical education in school, I have always been worried on applying what I received at the University, but the routine of classes was always demanding others doings. In this sense, there were many moments of epistemological ruptures occurred in my training, in which I always sought new investment in training to account for the provision of a more humanistic and grounded in real educational precepts physical education. To that end I had to reflect on the pedagogical interventions throughout my training, in order not to carry out the activities as heavy doings, but as metamorphoses of knowledge and thus generating learning for students. Thus, this dissertation fits into this context with the overall goal of discussing my professional career, considering the epistemological ruptures of Physical Education, occurred in my training and expertise. The objective is also to identify the contributions of these formations in professional activities, centered on storytelling and reflection of significant experiences in the teaching of sports and Physical Education. We highlight the paradigm shifts, leaving the gymnastic methods, through dance-physical education method, psychomotor, reaching the contemporary critical theories experienced from the culture of movement as well as its implications for professional practice. We chose a qualitative research, using the autobiographical method, using as sources or techniques, narratives, photographic recording and video samples. In the studies within the area of education, for the most part, qualitative research came to oppose the positivist view of the quantification on analysis of social phenomena. New ideas were appearing in order to present innovative perspectives to understand the real. The survey data will be presented in narrated form (descriptive), analyzed based on the theoretical framework that guides the study, especially authors who discuss school physical education, vocational training and body conception. We believe our study may be of relevance for training in Physical Education that as from pedagogical reflections in certain historical realities, envisions being able to open new perspectives for the performance of other physical education teachers

The nest architecture of the ant, Pheidole oxyops Forel, 1908 (Hymenoptera : Formicidae)

Pheidole oxyops builds subterranean nests, with an external architecture that is distinctive and easily recognizable by its wide and specific entrance hole, measuring up to 12.2 cm in diameter, denoting a pitfall-trap. In order to study the nests'internal architecture, seven nests were excavated; four were identified with neutral talc, while the others were cast in cement and then excavated. Measurements were made in order to gain a better understanding of their structures, and a photographic documentation was obtained as well. The excavations revealed that the nests are perpendicular relative to the ground, beginning with a cylindrical channel with a mean length of 13.5 cm, containing irregular formations, and whose diameter becomes progressively narrower until the first chamber is formed. As the channel continues, dish-like chambers appear, interconnected by channels that become progressively narrower and longer, while the chambers are arranged at greater distances from each other as nest depth increases. Both channels and chambers are located on the vertical projection of the entrance hole. Nests may reach a depth of up to 5.09 m, with a number of chambers ranging between 4 and 14.

Estudo de sistemas microemulsionados utilizando água do mar na recuperação avançada de petróleo

Petroleum exists in the nature in certain underground formations where it is adsorbed into the rocks pores. For the conventional recovery methods usually only 30% of the oil is extracted and this can be credited, basically, to three aspects: high viscosity of the oil, geology of the formation and high interfacial tensions between the reservoir s fluids. The enhanced recovery methods use the injection of a fluid or fluids mixture in a reservoir to act in points where the conventional process didn't reach the recovery rates. Microemulsion flooding, considered an enhanced method, has the purpose to desorb the oil from the rock formation and to attain an efficient displacement of the oil emulsion. With this in mind, this work was accomplished with two main objectives: the study of the parameters effect that influence a microemulsified system (surfactant and cosurfactant types, C/S rate and salinity) and the evaluation of displacement efficiency with the microemulsions that showed stability in the rich aqueous area. For the analyzed parameters it was chose the microemulsions composition used in the recovery stage: 25% water, 5% kerosene, 46.7% of butanol as cosurfactant and 23.3% of BC or SCO cosurfactant. The core plugs of Assu and Botucatu sandstones were appraised in porosity and permeability tests and then submitted to the steps of saturation with seawater and oil, conventional recovery with water and enhanced recovery with the selected microemulsions. The Botucatu sandstone presented better recovery parameters, and the microemulsion composed with BS surfactant had larger recovery efficiency (26.88%)

Diagnóstco geoambiental e avaliação de uso e ocupação do campo de dunas da zona especial de interesse turístco II (ZET-II) Natal/RN

The accelerated pressure of use and occupation of Rio Grande do Norte coastline in the last two decades presented the tourism as its main vector, having as a consequence a strong, articulated and growing real estate speculation of this area. In the Natal County there is a Zona Especial de Interesse Turistico II (Special Zone of Tourism Interest II) (ZET-II), consisted of urban beaches with approximately 8.5 km that is an important seashore of the city. The purpose of this research was identification, characterization and assessment of the process of use and occupation of dunes fields emphasizing the role of ZET-II, whereas the specific goals was the analysis of weather, geology and geomorphology, characterization of use and occupation of soil, and elaboration of an environmental diagnosis with identification and description of its mains consequences. The result of this work was the delineation of geologic-geomorphological map of the area with identification of principals units, determining its use and occupation, the measurement of the area already occupied by equipments, besides the description of the environmental impacts on dune fields: devastation, coastline erosion, ocean pollution by sewer and pluvial waters, contamination of groundwater, distribution inadequate of solid residues, landscape degradation, and occupation of seashore through the privatization of public areas. Concluding that the degrading changes occurred in this areas are resulting from the nature of use and urban seashore regulations, which have been diminishing the natural aspect, altering the landscape definitely, compromising the quality of hydro resources and altering its use, privatizing the areas between tides, complicating the population access and obstructing the scenery visualization of dunes and ocean. There is an urgent necessity of improvement of public politics in order to improve the strategies and organization of use and occupation of space urban-coastline

Gochnatia polymorpha (Less.) Cabrera (Asteraceae) changes in leaf structure due to differences in light and edaphic conditions

Gochnatia polymorpha (Less.) Cabrera é uma espécie de Asteraceae com ampla distribuição no bioma cerrado, sendo encontrada em diversas fisionomias florestais da região sudeste do Brasil. O presente estudo descreve alguns caracteres anatômicos foliares dessa espécie e os analisa quantitativamente em função de sua ocorrência nas formações florestais e também das diferenças de luminosidade. Foram encontradas diferenças quantitativas em todos os parâmetros anatômicos analisados. Os resultados demonstram que a alta plasticidade anatômica foliar nesta espécie pode ser considerada como uma vantagem adaptativa que a permite ocorrer em diversos ambientes do cerrado.

An evergreen neotropical savanna tree (Gochnatia polymorpha, Asteraceae) produces different dry- and wet-season leaf types

Gochnatia polymorpha (Less.) Cabrera is a widespread tree species found in different physiognomies of neotropical savanna (cerrado) formations of south-eastern Brazil. The present study describes some leaf anatomical characteristics of this species as a function of the time of leaf flush, during dry or wet seasons. This species presents anatomical plasticity in the cuticle, palisade parenchyma and abaxial epidermis as well as in stomatal size and stomatal and trichome density, which are leaf structures linked with water-status control. Leaf structure changed to suit the particular environmental conditions during dry and wet seasons. The production of different wet-and dry-season leaf types in G. polymorpha could be a response to drought and an adaptation to environmental constraints in the cerrado.
