Otimização de um sistema de distribuição predial de água fria: estudo de caso

This dissertation presents a methodology to the optimization of a predial system of cold water distribution. It s about a study of a case applied to the Tropical Buzios Residential Condominium, located in the Búzio s Beach, Nísia Floresta city, the east coast of the Rio Grande do Norte state, twenty kilometers far from Natal. The design of cold water distribution networks according to Norm NBR 5626 of the ABNT - Brazilian Association of Techniques Norms, does not guarantee that the joined solution is the optimal solution of less cost. It s necessary the use of an optimization methodology, that supplies us, between all the possible solutions, the minimum cost solution. In the optimization process of the predial system of water distribution of the Tropical Búzios Condominium, is used Method Granados, that is an iterative algorithm of optimization, based on the Dynamic Programming, that supplies the minimum cost s network, in function of the piezometric quota of the reservoir. For the application of this Method in ramifies networks, is used a program of computer in C language. This process is divided in two stages: attainment of the previous solution and reduction of the piezometric quota of headboard. In the attainment of the previous solution, the minors possible diameters are used that guarantee the limit of maximum speed and the requirements of minimum pressures. The piezometric quota of headboard is raised to guarantee these requirements. In the second stage of the Granados Method, an iterative process is used and it objective is to reduce the quota of headboard gradually, considering the substitution of stretches of the network pipes for the subsequent diameters, considering a minimum addition of the network cost. The diameter change is made in the optimal stretch that presents the lesser Exchange Gradient. The process is locked up when the headboard quota of desired is reached. The optimized network s material costs are calculated, and is made the analysis of the same ones, through the comparison with the conventional network s costs

Cuidados paliativos e ser-para-morte: reflexões sobre um atendimento psicológico

Death is a theme that fascinates, though at the same time, frightens and uneasy the human being, despite the finitude being present at our daily lives. In each historical time, death has been represented in a peculiar way, from familiar death (at Middle Ages), to interdicted death (at contemporary times). Through this path it‟s possible to recognize several attitudes and stages front of death and the process of dying as possibilities of coping and the understanding of these occurrences. In other hand, the palliative care proposal came as a humanized attention, front of the human finitude, recognizing death as a part of the vital cycle. The Brazilian reality, in this context, still faces a lot of political, economic and social barriers that makes difficult the consolidation of palliative care at the death process in the Brazilian Health Care policies. Currently, according to the Brazilian Palliative Care Association, Brazil presents an average of 40 services with this proposal. Such data portray our inexpressive condition in relation to these cares when considering the territorial extension and population of our country. Considering this scenario is relevant think about death and the process of dying at contemporary times, at a health context in which palliative care, when trying to humanize the process of dying, bring to light the issue of human finitude and the beingtowards- death, as thought by the philosopher Martin Heidegger. According to him, the human being (Dasein) is constituted as a being-towards-death, once death is its most own potentiality-for-bein and its last possibility to be lived. In view of the ideas presented, the proposed study appears as a qualitative research of existential-phenomenological inspiration and aims to understand the experience of being-toward-death from the psychological care to a person out of possibilities of cure living on palliative cares. The psychological care happened at the patient‟s home, understanding the clinical process of being-with-the-other from the written reports of the psychology/researcher, by the accompanying sessions, configured as an experience report. These reports are focused on the experiences lived by the patient, as well as apprehended by the psychologist at the intersubjectivity relation and its own experience with Dasein and, therefore, being-toward-death. The reports were hermeneutically interpreted, from the senses that emerged in this process, considering the notion of being-toward-death proposed by Heidegger. Furthermore, it was important to dialogue with other authors that approached the studied theme. It is perceived, through brief and meaningful reflections about the clinical treatments started, that the experience of illness with no possibilities of cure makes the Dasein revises feelings and experiences that were marked at the temporality and historicity of existence. It is a stage of life in which the cultural dimension and the common sense of finitude, often gains ground in the human condition, taken in its ordinary sense, unlike the way it has been thought from an ontological and existential perspective of death. Thus, there are singulars and revealing paths in the palliative care scenery as possible ways for authenticity of being-toward-death

Movimento estudantil e serviço social no capitalismo contemporâneo: tendências e particularidades

This dissertation aims to analyze the social direction in which the Student Movement in Social Work in Brazil (ENESSO) has gone through. This is done considering how the functioning of the National Executive, the Brazilian Social Work Student union has operated. The research analyzed their political position regarding the university as well as professional education in the period of 2003 to 2008. The study s theoretical and methodological object was obtained according to its structural, juncture, and time determinants. All of the mentioned elements considered the contemporary capital crisis and its implications towards the State and Society emphasizing specifically the changes that occurred in the University regarding professional education. For the purpose of data collection and production, a documental and field research was realized. Thus, interviews were done considering one manager of each management period of the ENESSO group in the time span of 2003 to 2008. Some subjects that represented the Brazilian Social Work Teaching and Research Association (ABEPSS) as well as were also interviewed. These subjects have had a relevant role in partnership with these entities and represented students in the contemporary scene. Results suggest that ENESSO has developed work that defends a project of a public, free and laic quality university. This entity also defends a project that considers the 1996 Curricular Guidelines. Currently, there is internal dispute in the social direction of the MESS, this is seen amongst political groups that diverge in opinions related to the analysis done by the Lula government regarding the political role that the National Student Union-UNE has taken in the counter-reform of higher education. This current juncture is seen as extremely individualist and it results as in unfavorable for the collective organization of the working class, especially regarding student movement. MESS has been going through a moment of profound instability and this dimension is being expressed by the absence of national coordinator for the 2008/2009 management period at ENESSO. Even though there are difficulties, it is possible to point out partnership of the entities that represent the national Social Work in Brazil. These partnerships are all related to a struggle and search for the development of a professional project that leads towards the sociability awareness that goes beyond capital.

Estudo integrado geológico/tecnológico de rochas ornamentais: os granitos flores e jacarandá, RN

The main purpose of the present study is to integrate a geological and technological investigation of ornamental rocks of the Flores and Jacarandá granites, which are located near the Afonso Bezerra city, in the north central part of the Rio Grande do Norte State. The study area encompasses four litho-stratigrafic units: a Gneiss-Migmatitic Complex(cristalline basement), which is mainly composed of banded gneisses, usually deformed as mylonitic rocks and with several migmatic features, an Augen Gneiss, which occurs as an elongated body that constitutes the Jacarandá granite, a small granite stock, which presents a semi-circular form, named Flores granite, composed of pink, fine to medium coarse rocks, and fine to coarse alluvial sediments, which form extensive areas of large fluvial deposits. The technological characterization of the Flores and Jacarandá granites, carried out through several tests, has as the main purpose the determination of petrographic, physical, and mechanic parameters that allowed the characterization of these rocks. The test followed procedures recommended by Brazilian (ABNT Associação Brasileira de Normas Técnicas) and foreigner institutions (ASTM American Society for Testing and Materials). The petrografhic analysis indicated that the rocks investigated are granite sensu estrictu, summing an average 85-90% modal. The Flores granite is the more felsic rock, which presents mafic content ∼ 10% and monzonitic composition. The Jacarandá granite is an Augen Gneiss rock that presents sienogranitic composition and mafic modal content ∼ 15%. Several technological tests carried out (alterability, physical indices, velocity of ultrasonic wave propagation, uniaxial compression, flection resistence, Amsler desgaste, and resistence to freezing and heating) indicated that parameters and values were identical for both granites investigated. These parameters and values are consistent with the Brazilian and international standards for siliciclastic rocks of ornamental use, as well as other Brazilian ornamental granites. The analysis of all results indicates that both the Flores and Jacarandá granites present good quality, and that they are indicated for ornamental use of revetment interior and exterior of buildings
