Turismo e pobreza: percepções dos guias de turismo, moradores e não moradores que trabalham na favela da Rocinha Rio de Janeiro

This project refers to a study somewhat controversial , as in focusing less recognized and valued hand, although the dynamics of tourism pass to take another view , you can not beforehand consider favorable or unfavorable . Analyzes the phenomenon related to conception or perception of poverty from tourism residents and non residents of the Favela of Rocinha in Rio de Janeiro tourist guides . It is a subject to an object of research somewhat controversial , but about which there is already an academic and scientific concern and deserves an investigator look. Fits as a qualitative study whose methodological procedure based on interviews and participant observation , and the geographic divisions chosen the Rocinha slum , for its expressiveness and for being a pioneer in this type of tourism , had to conducting fieldwork lasting six months, which was accompanied by at least four hours walking work of sixteen tour guides, eight residents and eight non- residents in the community, working for different travel agencies and tourism. End of each tour, all tour guides answered a semi-structured questionnaire, containing nineteen questions. Most respondents tour guides authorized record interview, which has made it possible to analyze the speech through spoken language. In tourism, foreign tourists are the main target, although rarely also count with the participation of domestic tourists. Notes that the relationship between poverty and slums, from the perceptions of tourist guides residents better reflects the reality of favela residents compared with non residents guides, since they fully know all the intricacies and better the difficulties they have endured and still go, when it comes to the issue of stigmatization respect, by which has suffered by Brazilian society, in relation to live in slums, and have your dwelling place as a tourist attraction. While presenting the social reality of Rocinha consistently during his work, the non residents guides worry about being as natural as possible with tourists as much as the locals show slum, in the same way they avoid authorize tourists to take compromising photos and that will expose the intimacy of community residents . Concludes that, while recognizing the importance of elevation to the rank of tourist attraction and its promising prospects, requires attention and priority, given the greater precariousness of the human condition in relation to the prime areas in which it operates tourism should be a vector of development, not a masking of reality

Sistemas de dunas do parque das Dunas e Barreiras do Inferno/Natal (RN: levantamento geológico /geofísico, elaboração do modelo deterministico e avaliação da vulnerabilidade/suscetibilidade

The current work was developed on the dune systems of the Parque das Dunas and Barreira do Inferno. These places are located in the cities of Natal and Parnamirim (RN, Brazil), respectively. This project has the purpose of developing the deterministic model on a specific blowout at Parque das Dunas, based in the geophysical interpretations of the lines gotten with the Ground Penetration Radar and the planialtimetric acquisitions of the topographical surface of the land. Also analyses of the vulnerability/susceptibility of these dune systems had been done in relation to the human pressures. To develop its deterministic model, it is necessary to acquire inner and outer geometries of the cited blowout. In order to depict inner geometries underneath the surface are used the GPR observing the altimetric control for topographical correction of the GPR lines. As for the outer geometries, the geodesic GPS gives us the planialtimetric points (x, y and z points) with milimetric precision, resulting in high-resolution surfaces. Using interpolation methods of the planialtimetric points was possible create Digital Elevations Models (DEM´s) of these surfaces. As a result, 1,161.4 meters of GPR lines were acquired on the blowout at the Parque das Dunas and 3,735.27 meters on the blowout at the Barreira do Inferno. These lines had been acquired with a 200 MHz antenna, except the 7 and 8 lines, for which we had been used a 100 MHz antenna. The gotten data had been processed and interpreted, being possible to identify boundary surfaces of first, second and third order. The first order boundary surface is related with the contact of the rocks of the Barreiras Group with the aeolian deposits. These deposits had been divided in two groups (Group 1 and Group 2) which are related with the geometry of stratum and the dip of its stratifications. Group 1 presented stratum of sigmoidal and irregular geometries and involved bodies where the reflectors had presented dips that had varied of 20 to the 28 degrees for the Parque das Dunas blowout and of 22 to the 29 degrees for the Barreira do Inferno blowout. Usually, it was limited in the base for the first order surface and in the top for the second order surface. Group 2 presented stratum of trough, wedge or lens geometries, limited in the base for the second order vi surface, where the corresponding deposits had more shown smoothed reflectors or with dips of low angle. The Deterministic and Digital Elevation Models had been developed from the integration and interpretation of the 2D data with the GOCAD® program. In Digital Elevations Models it was possible to see, for the localities, corridor or trough-shaped blowouts. In Deterministic Model it was possible to see first and second order boundary surfaces. For the vulnerability/susceptibility of the dune systems it was applied the methodology proposal by Boderè al (1991); however the same one did not show adequate because it evaluates actual coastal dunes. Actual coastal dunes are dunes that are presented in balance with the current environmental conditions. Therefore, a new methodology was proposal which characterizes the supplying and activity sedimentary, as well as the human pressures. For the methodology developed in this work, both the localities had presented a good management. The Parque das Dunas was characterized as a relic dune system and the Barreira do Inferno was characterized as a palimpsestic dune system. Also two Thematic Maps had been elaborated for the environmental characterization of the studied dune systems, with software ArcGis 8.3, and its respective data bases

O papel da solidariedade desempenhado por familiares visitantes e acompanhantes de adultos e idosos hospitalizados

Este estudo objetivou compreender o papel da solidariedade desempenhado por familiares visitantes e acompanhantes de adultos e idosos internados. Utilizou-se como referencial teórico a teoria de enfermagem como cuidado solidário e como referencial metodológico a Grounded Theory. Foram entrevistados nove familiares de adultos e idosos hospitalizados no período de abril a setembro de 2002. Dos resultados identificou-se o fenômeno: assumindo o papel de familiar visitante ou de familiar acompanhante, que congrega os temas: querendo desempenhar um papel solidário e compreendendo o estar junto como uma interdependência emocional. Acredita-se que quando a enfermeira reconhece a singularidade da relação de solidariedade e de interdependência familiar, também exerce seu trabalho pautado na solidariedade, visto que colabora para o restabelecimento do doente, alivia seu sofrimento e de seus familiares e, portanto, promove a saúde do grupo familiar.

Atividade predatória de Euseius citrifolius Denmark & Muma (Acari: Phytoseiidae) sobre Tenuipalpus heveae (Acari: Tenuipalpidae)

The rubber tree red false spider mite, Tenuipalpus heveae Baker, is an important pest of Hevea brasiliensis (Willd. ex. Adr. de Juss.) Muell. Arg. The phytoseiid mite Euseius citrifolius Dennmark & Muma has frequently been recorded on rubber tree crops. The objective of this work was to determine the predatory activity of E. citrifolius on the different life stages (egg, larva, nymph and adult) of T. heveae. The experiments were carried out in Petri dishes (9-cm diameter) containing a layer of wet cotton inside, onto which a disk of rubber tree leaf (2.5-cm diameter) was laid. The disks were taken from naturally infested leaves. Twenty specimens in the life stage that was to be tested were left on the disk and the others were eliminated; a predator life stage (larva, nymph or female) was obtained from a laboratory stock colony and put into each dish. For each tested life stage of E. citrifolius, 4 treatments (T. heveae life stages) and 20 replications were considered in a randomized block design. The observations were made after 24 hours for larvae and nymphs of the predator, and after 24, 48 and 72 hours for the females. E. citrifolius larvae and nymphs had a higher preference for T. heveae larvae followed by nymphs, eggs and adults. Within 72 hours, each predator female consumed 15.0 larvae, 14.5 nymphs, 7.4 adults or 2.2 eggs of T. heveae. It is concluded that E. citrifolius can feed on red false spider mites, the larva and nymph being the preferred stages.

Experimental analysis of heat recoveries with heat pipes operating in low inclination angle

Heat recovery devices are important in the optimization of thermal systems, since they can be used to reduce thermal losses to the environment. The use of heat pipes in these types of equipment can provide heat recoveries of higher efficiency, since both fluid flows are external and there are less contamination risks between the hot and cold fluids. The objective of this work is to study a heat recovery unit constructed with heat pipes and mainly, to analyze the influence of the inclination of the heat pipes on the performance of the equipment. For this analysis, a heat recovery unit was constructed which possesses 48 finned heat pipes in triangular geometry, the evaporator and condenser being of the same length. This unit was tested in an air-air system simulating a heat recovery process in which heat was supplied to the hot fluid by electrical resistances. The results have shown that there exists an inclination at which the system has a better performance, but for higher inclinations there is no significant increase of the efficiency of the system. This paper also presents the influence of inclination of heat pipes on effectiveness and NTU parameters which are important in heat exchanger design.
