Avaliação da disponibilidade hídrica e da demanda hídrica no trecho do Rio Piranhas-Açu entre os açudes Coremas-mãe D´água e Armando Ribeiro Gonçalves

Piranhas-Açu basin is a Federal watershed with a drainage area of 43.681,5 km2, sited at Brazilian northeast semi arid, with 60% of your area in Paraiba State and 40% in Rio Grande do Norte State. The main river, Piranhas-Açu, has strategic importance for development of these states, because it s an essential source for many socio-economics activities developed along watercourse. The river s reach between Coremas-Mãe D`água Dam and Armando Ribeiro Gonçalves Dam has many irrigation projects, and supply many riverside cities. All this activities practiced in this river s reach consumes high water volumes. Due the importance of this stream and the necessity of an adequate management, this work aims for an impartial and detailed evaluation of real water supply conditions in this river s reach, by the application of hydrological modeling, including the arrangement of main dams in tributaries, and storage reservoir water balance. The rainfall-discharge model s applied in each sub-basins it was selected the model MODHISA- Hydrological Model of Semi Arid, that is a concentrated model with easy application. The simulation produced 50 years of inflows into the reservoirs, for which, were constructed the guaranties curves; and produced 50 years of synthetic discharge data in relevant points on the river and on its affluents; so it was constructed the permanence curves. Confronting the available discharge with the current and futures volumes of raw water captured in this river s reach, it was verified that de demands have high guaranties. This work concluded that the MODHISA Model is suitable to reproduce the hydrologic characteristics of Piranhas-Açu sub-basins, and showing good results

Uma abordagem histórica para o ensino do princípio da inércia

Placed in the field of Didactic of Science, this paper proposes an approach to the introduction of the History of Science in science education, at high school level. It was designed and implemented a series of activities regarding the history of the Principle of Inertia. The aim of this approach was to give more meaning to scientific education, while opening new avenues for a better understanding of the processes of construction of scientific knowledge. The preparation of the activities involved a study of the historical development of the concept of motion, from the Aristotelian physics through physical movement concepts at medieval period, from Galileo, Gassendi, Descartes, until the first law of Newton. The strategy of teaching was applied to three classes of high school (night period) of a state public school at the city of Natal (RN). The results indicated the difficulty of overcoming alternative conceptions about movement by students. Nevertheless, we consider that the implementation of this strategy of teaching both represented gains for the learning of students, and contributed to the resizing of pedagogical practices of the teacher-researcher

Nexus: da relacionalidade do princípio à metafísica do inominável em Nicolau de Cusa

We indicate the idea of nexus or conexio, thought of as intelligible connection with the intelligent, the foundation on which the reason why you can understand and name, even if inadequately, what the intellect sees incomprehensible and unnameably. Thus, it opens a way for our research: we will take the idea of nexus as fundamental to the interpretation of the divine names and the "metaphysics of the unnameably" and we show how the divine names, mainly in possest, mirrored in the Trinity, relatedness of the principle and therefore also the nexus. For that you need to think some preliminary questions: we will place Nicholas of Cusa in the tradition of medieval Christian Neoplatonism, we resume some discussions on the problem of naming and the philosophy of language in his thinking, we will reflect such thinking is molded from active dialogue with the tradition and how it is your speculation is founded upon the dynamic and dialectical relationship between philosophy and theology to be thought of in our text using the relationship between faith and understandig (intellectus). After introductory clarify these issues we will come to consider introductory understanding of the Trinitarian Beginning and speculation about the nexus taking as its starting point from where the De venatione sapientiae nexus or conexio is designed as a hunting field of wisdom and the First Book of De docta ignorantia where the maximum is now thought of as one and triune. From the Second Book of the same work and the Idiota. De mente we will show in what sense the universe and men, as imago dei, imitate the eternal Trinity. Finally, we will resume the notion of the scientia aenigmatica of De beryllo and some information that will clarify that Nicholas assumes the divine names as enigmas. Finally, we will try to show that the enigmatic or symbolic names also mirror the triune Beginning principle. So, before we return some traces of this aspect in some divine names and texts of the "late period" and then conclude with that which in itself already indicates the nexus and therefore the trinity: possest

O princípio metafísico da poética de Aristóteles

Aristotle's definition of tragedy indicates a metaphysical project insinuated by a notion of kátharsis. The reconstruction of Aristotle's method of definition is inspired in the concepts of enérgeia and dýnamis taken from Physics, understanding cause as substance. The Doctrine of the Four Causes is the theoretical basis of the definition of tragedy, placing tragedy in the genre of imitation and distinguishing its species: language (material cause), noble and complete action (formal cause), actors (efficient cause) and kátharsis (temporarily identified with the final cause). Nevertheless, there is no final cause in the definition of tragedy. The kátharsis of passions is experienced by the spectator when he witnesses tragedy, which is the imitation of a noble action, executed by actors and not narrated. Aristotle justifies hid proposition in favor of mimesis by assuming that imitation is natural to man since infancy and the view of objects allows whoever contemplates them to identify and learn the originals. As a metaphysical principle, kátharsis is projected to beyond definition of tragedy, where it is manifested cathartically, in the spectator. Research about the spectator brings one back to the definition of tragedy, where the imitation is an imperfect copy which evokes in the spectator the presence of the originals of the imitated sentiments, thus realizing the kátharsis of these emotions. In this way kátharsis reveals itself as selfknowledge and approach of divine truth and perfections.
