Zoneamento geoambiental como subsídio ao planejamento territorial municipal: estudo de caso para Currais Novos/RN

This paper presents the master plan and geoenvironmental zoning natures as instruments of environmental planning and management. The discussion of territory environmental planning is guided by two directions: at first the environmental elements involved in planning and the another is the implementation of these instruments at the municipal territory. To analyze the planning directed of the municipal territory we consider the fragments of its, represented by country and urban. The master plan inside of the Estatuto da Cidade (City Statute) and the geoenvironmental zoning are directed to territorial environmental planning. Regarding of the master plan the first challenge has been the spacial area that the plan can cover. It is necessary to prepare master plans that could include all the territory. The environmental zoning are directed for the territory totality.In this sense, the geoenvironmental zoning of the Currais Novos was done in the totality of the municipal territory and guided by the environmental physics variables. The geoenvironmental zoning sets in a planning and ordering of the territory instrument based in the landscape analysis. Therefore grounded in the Geosystems‟s Theory this work has like a main objective to propose a geoenvironmental zoning for the Currais Novos Municipality in RN. So, was used an analysis technique suggested for Bardin (2010) and the Currais Novos‟s physical environment characterization through of the fieldwork and cartographic data vectorization, beyond the image‟s treatment SRTM. The geoenvironmental systems definitions were based in the suggestion of Cestaro, et al. (2007) support in Bertrand (1968). For both were identified five geoenvironmental systems: Borborema Plateau, Residual plateau, Chapada da Serra de Santana, semiarid river valley and lagoon valley and eleven geoenvironmental subsystems: Borborema Plateau Western Slope, Isolated Massif of the Borborema Plateau, Residual Crest, Residual Massif, Erosional Scarp of the Chapada, flat top plateau, fluvial plains, temporary river of the semiarid and ornamental water or sluice

Evolução top-hat hidrodinâmica em campos de velocidades peculiares primordiais

We investigate the cosmology of the vacuum energy decaying into cold dark matter according to thermodynamics description of Alcaniz & Lima. We apply this model to analyze the evolution of primordial density perturbations in the matter that gave rise to the first generation of structures bounded by gravity in the Universe, called Population III Objects. The analysis of the dynamics of those systems will involve the calculation of a differential equation system governing the evolution of perturbations to the case of two coupled fluids (dark matter and baryonic matter), modeled with a Top-Hat profile based in the perturbation of the hydrodynamics equations, an efficient analytical tool to study the properties of dark energy models such as the behavior of the linear growth factor and the linear growth index, physical quantities closely related to the fields of peculiar velocities at any time, for different models of dark energy. The properties and the dynamics of current Universe are analyzed through the exact analytical form of the linear growth factor of density fluctuations, taking into account the influence of several physical cooling mechanisms acting on the density fluctuations of the baryonic component of matter during the evolution of the clouds of matter, studied from the primordial hydrogen recombination. This study is naturally extended to more general models of dark energy with constant equation of state parameter in a flat Universe

A injunção em livros didáticos de língua portuguesa do 4º e 5º anos do ensino fundamental

This investigation aims at identifying, describing, analyzing and interpreting how textbooks on Portuguese Language approach, beginning with the linguistic material, the effects of sense in texts that predominately employ injunctives. The corpus of this study is comprised of six collections of textbooks on Portuguese Language, which are part of the National Program Guide for Textbooks (PNLD) from 2010, adopted by the public schools in the city of Natal and the object of study for the Read/Tell Project of the Educational Observatory of the Federal University of Rio Grande do Norte (UFRN). Textbooks from the 4th and 5th grades, Elementary School, were analyzed – 12 copies total. For the analysis, we selected 16 writing proposals of injunctive texts. Our study is based on theoretical discussions by Adam (2001a, 2001b) with regard to the genre of: inciting to action. In addition, we consider the work of Koch and Fávero (1987), Koch and Elias (2009), Marcuschi (2003, 2008) Pery-Woodly (2001), Rodrigues (2013), Travaglia (1992, 2007) and Rosa (2007). With respect to discussions on textbooks, we refer to Choppin (2004, 2009), Batista (2003, 2009), Rojo e Batista (2005), and with regard to Portuguese Language textbooks specifically, we consider Soares (1998, 2001, 2004) and Bunzen and Rojo (2005). The proposals for writing in injunctive texts, in the collections analyzed, are tips/recommendations, instructions on making toys and/or games, travel itineraries and cooking recipes, such that 69% of them appear in the 4 th grade textbooks and only 31% appear in the 5th grade textbooks. With respect to the linguistic elements responsible for the construction of directive speech acts and the effects on sense produced by them, the data shows that 50% of the writing proposals do not exploit linguistic categories that implicate the effects on sense using injunctives, or rather, there is no work done dealing with linguistic analysis, while 33% mention the imperative mode and 17% investigate infinitive verbs. In this dissertation, the textual plans of incitation to act genres were studied and in them the linguistic materiality that vehicles injunction. This study might contribute to the improvement of Portuguese language teaching in what concerns the articulation of grammatical studies to textual sequences/types, mainly in the case of Portuguese language textbooks for the 4th and 5th grades of Elementary School.

A escrita no Ensino Fundamental II: uma análise dos desvios ortográficos e sugestões de estratégias de intervenção

This paper presents a reflection on the written language, a social practice that is increasingly strengthened in everyday life. Unveiling its nature, organization and function must be the first step for teachers to change their posture towards the teaching of this linguistic mode, helping students use it more effectively and securely. Considering these principles, this dissertation seeks to understand on the light of contemporary linguistic theories, the factors that influence the writing deviations were found in the text production of students of the 8th grade of elementary school II, enrolled in a public school in Rio Grande do Norte, whereas those deviations reveal the beginning of learning of this communication tool, representing the first hypotheses raised by students to dominate it. To analyze the data we used the works done by Lemle (1995), Cagliari (2009), Carraher (1985), Zorzi (1998), Guimarães (2005), Miller (2008), Veçossi (2010), among others, starting from of which, the scientific production on reading and writing learning come developing. The results of this analysis showed that the writing deviations present in the texts of the students are motivated not only by lack of knowledge of standard orthographic of the Portuguese language, but, also, stem from phonetic, phonological and grammatical factors. Thus, we seek to present new teaching and learning strategies of writing that might lead students to reflect on the use of the same, developing this ability more critically and creatively. We believe that the activities presented can minimize writing with orthographic deviations or linguistic variation practiced by students.
