Análise da eficiência do cobre, alumínio e PVC como condutores hidráulicos em aquecedores solares

One of society concerns are preserving the environment and the growing energy demand. These two issues are in conflict since most of the energy used today in some way harms the environment. Then is essential to develop and implement ways to clean and renewable energy. In this way, solar energy stands out as a source of clean energy, renewable, abundant and acessible. Solar energy can be harnessed by photovoltaic cells or by solar collectors. The aim of this article is analysethe yield of the solar heather assembled with hydraulic conductive and plastic bottles using three different materials for hydraulic conductors, in order to compare these efficiences and analyze material which has the best cost-benefit in this type of application. The materials analyzed in this study were copper, aluminum and PVC. For this analysis were assembled three alike solar heaters using each one of these materials, and were done several series of measurements of the temperature water output to each heat with flow between 10 and 30 liters per hour. With these data we can analyze the yield and the performance of copper, aluminum and PVC in this application. So we can conclude that aluminum has a higher efficiency, followed by PVC, and the copper had the lowest efficiency. This behavior kept for all values of flow rates examined

Relações públicas e serviços virtuais: a comunicação entre as corporações da internet e o cibernauta

The objective of this study is to adress the action possibilities of the Public Relations professional in management of communication between the virtual services companies and their customers – the cybernauts. For this purpose, a bibliographical research was made about the cyberspace, Internet environment, as well as the cyberculture and the on-line consumer public. It was also studied the possible areas of Public Relations's action, their work tools and means of communication with the customer, in order to verify the specificities of communication mediated by new technologies. Based on these concepts, it was possible to propose an action of this professional in the organizations called dotcom, in order to contribute to the management of the communication flow between companies and this “invisible” public, which relates virtually to the organization, establishing different modes of interaction in relation to tradicional customers, requiring different strategies of relashionsip

Linear relationship between potential and concentration in flow potentiometry

In potentiometric-flow systems, linear-potential responses for logarithmic concentrations can be attained for first-(or pseudo-first-) order reactions in which the monitored chemical species react with the analyte during a fixed time interval. To demonstrate this property, the determination of glycerol based on its oxidation by periodate and potentiometric monitoring of the remaining periodate was selected. Influence of reagent concentration and timing on the linearity of the analytical curve were investigated. A mathematical treatment was derived, and potentialities/limitations of the approach were outlined. The system was applied to analysis of soap and lixivia samples. The analytical curve within 200 and 2000 mg L-1 (r = 0.99975; n = 5) was described as E = 8.166 + 0.0478 (glycerol). The sample throughput was 100 h(-1), and a measurement repeatability within 0.5 mV was always observed. By applying a t-test, there was no statistical difference between the results obtained by the proposed procedure and by iodimetric titration at the 95% confidence level.

DIAGNOSIS of REGIONAL CEREBRAL BLOOD FLOW ABNORMALITIES USING SPECT: AGREEMENT BETWEEN INDIVIDUALIZED STATISTICAL PARAMETRIC MAPS and VISUAL INSPECTION BY NUCLEAR MEDICINE PHYSICIANS WITH DIFFERENT LEVELS of EXPERTISE IN NUCLEAR NEUROLOGY

INTRODUCTION: Visual analysis is widely used to interpret regional cerebral blood flow (rCBF) SPECT images in clinical practice despite its limitations. Automated methods are employed to investigate between-group rCBF differences in research Studies but have rarely been explored in individual analyses.OBJECTIVES: To compare visual inspection by nuclear physicians with the automated statistical parametric mapping program using a SPECT dataset of patients with neurological disorders and normal control images.METHODS: Using statistical parametric mapping, 14 SPECT images from patients with various neurological disorders were compared individually with a databank of 32 normal images using a statistical threshold of p<0.05 (corrected for multiple comparisons at the level of individual voxels or clusters). Statistical parametric mapping results were compared with Visual analyses by a nuclear physician highly experienced in neurology (A) as well as a nuclear physician with a general background of experience (B) who independently classified images as normal or altered, and determined the location of changes and the severity.RESULTS: of the 32 images of the normal databank, 4 generated maps showing rCBF abnormalities (p<0.05, corrected). Among the 14 images from patients with neurological disorders, 13 showed rCBF alterations. Statistical parametric mapping and physician A completely agreed on 84.37% and 64.28% of cases from the normal databank and neurological disorders, respectively. The agreement between statistical parametric mapping and ratings of physician B were lower (71.18% and 35.71%, respectively).CONCLUSION: Statistical parametric mapping replicated the findings described by the more experienced nuclear physician. This finding suggests that automated methods for individually analyzing rCBF SPECT images may be a valuable resource to complement visual inspection in clinical practice.
