Estudos que avaliaram o uso da vibra??o de corpo inteiro (VCI) em pacientes com DPOC demonstraram melhora em par?metros cl?nico-funcionais, contudo, o conhecimento a respeito do efeito agudo da VCI na DPOC ainda ? escasso O estudo teve como objetivo, caracterizar a intensidade do exerc?cio em diferentes frequ?ncias de VCI e dos tipos de agachamento (est?tico ou din?mico) durante uma sess?o de exerc?cio, bem como, avaliar o efeito agudo do exerc?cio sobre as respostas cardiorrespirat?rias e inflamat?rias na DPOC.Os volunt?rios da pesquisa foram pareados quanto ao sexo, idade, IMC e foram divididos em 2 grupos, sendo eles: grupo controle (GC, n=13), composto por sujeitos sem DPOC e grupo DPOC (DPOC, n=13). A familiariza??o e aplica??o do Teste de Caminhada de 6 minutos foram realizadas em 1 dia, ap?s 1 semana, a caracteriza??o com o exerc?cio de VCI foi realizada em 4 dias com um intervalo de 48 horas entre as sess?es. O agachamento est?tico foi realizado nas frequ?ncias 30, 35 e 40 Hz e o agachamento din?mico na frequ?ncia 35 Hz. Os dois grupos passaram pelas mesmas condi??es experimentais. Foram mensurados os par?metros cardiorrespirat?rios durante todos os dias de exerc?cio e os par?metros inflamat?rios foram avaliados durante o exerc?cio est?tico na frequ?ncia de 35 Hz atrav?s da concentra??o plasm?tica da adiponectina, resistina, IL-6, IL-8, IL-10, BDNF e receptores sol?veis de TNF (STNFR-1 e STNFR-2). Os resultados demonstraram que o agachamento est?tico promoveu maior varia??o (39,2%) na FC quando comparado ao din?mico. A an?lise nas 3 frequ?ncias de VCI demonstraram comportamento semelhante entre os grupos com aumentos significativos do VO2 (GC: 27,4 a 40% e DPOC: 21,5 a 28,5%) e da FC (GC: 10,2 a 12,5% e DPOC: 4,3 a 12,7%). Foram encontradas altas concentra??es basais das adipocinas e IL-8 e baixos valores de IL-10 no grupo DPOC. Ap?s a VCI foi observado aumento das concentra??es de IL-10 (40,6%) no grupo DPOC alcan?ando valores semelhante a concentra??o basal do GC. Em conclus?o, o presente estudo traz subs?dios para a elabora??o de protocolos de treinamento com a VCI, uma vez que o exerc?cio foi caracterizado como de baixa intensidade (<2 METs) nas frequ?ncias avaliadas, sendo aplic?vel e seguro na DPOC. Adicionalmente, a VCI parece modular as concentra??es de IL-10 na popula??o de DPOC avaliada. / Disserta??o (Mestrado) ?

Studies evaluating the use of whole body vibration (WBV) in patients with COPD have shown improvement in clinical-functional parameters, however, knowledge about the acute effect of WBV in COPD is still scarce. The objective of this study was to characterize the intensity (static or dynamic) during an exercise session, as well as to evaluate the acute effect of exercise on cardiorespiratory and inflammatory responses in COPD. The study volunteers were matched for gender, age, BMI and were divided into 2 groups: control group (GC, n = 13), composed of subjects without COPD and COPD group (COPD, n = 13). Familiarization with WBV exercise and the application of the 6-minute Walk Test were performed in one day, after 1 week, the characterization of the WBV exercise was performed in 4 days with a 48-hour interval between sessions. Static squatting was performed at frequencies 30, 35 and 40 Hz and dynamic squatting at 35 Hz frequency. Both groups underwent the same experimental conditions. Cardiorespiratory parameters were measured during all exercise days and inflammatory parameters were evaluated during static exercise at the 35 Hz frequency through the plasma concentration of adiponectin, resistin, IL-6, IL-8, IL-10, BDNF and soluble TNF receptors (STNFR-1 and STNFR-2). The results showed that static squatting promoted greater variation (39.2%) in HR when compared to dynamic. The analysis of 3 frequencies of WBV showed similar results between the groups with significant increases in VO2 (GC: 27.4 to 40% and COPD: 21.5 to 28.5%) and HR (CG: 10.2 a 12.5% e COPD: 4.3 a 12.7%). Baseline concentrations of adipokines and IL-8 showed higher values, in the other hand low IL-10 values were found in the COPD group. After WBV, an increase in IL-10 concentrations (40.6%) was observed in the COPD group reaching values similar to basal GC concentration. In conclusion, the present study provides subsidies for the elaboration of training protocols with WBV, since exercise was characterized as low intensity (<2 METs) in the frequencies evaluated, being applicable and safe in COPD. In addition, VCI appears to modulate IL-10 concentrations in the COPD population evaluated.

Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity / Um prot?tipo vibr?til autoflotador de acionamento eletromec?nico para tratamento de ?gua de produ??o de petr?leo e emuls?o cong?nere ? apresentado e avaliado. A produ??o de petr?leo para refinamento e obten??o de derivados ? realizada sob modalidades tecnicamente referidas como on-shore e off-shore, isto ?, no continente e no mar. No Brasil 80% da produ??o petrol?-fera ? feita no mar e ?rea de implanta??o e escala de custo s?o preocupantes. Associa-se ?gua oleosa de produ??o, efluente abundante em larga escala, carreadora de 95% do potencial polu-idor da atividade cujo destino final ? o meio ambiente mar?timo ou terrestre. Embora diversi-ficado conjunto de t?cnicas e sistemas de tratamento d ?gua encontram-se em uso ou pesqui-sa, prop?e-se um sistema inovador que opera de forma sustent?vel sem aditivos qu?micos, pa-ra o bem do ecossistema. Utilizou-se labirinto adsorvente, em espirais met?licos, e escala la-boratorial de fluxo. Patentes de equipamento e processo s?o reivindicadas. Realizaram-se tra-tamentos em vaz?es e faixas de frequ?ncia distintas, monitoradas com sistemas de controle, uns constru?dos, outros aquistados para tal. Medi??es do teor de ?leo e graxa (TOG) do eflu-ente tratado mantiveram-se dentro do intervalo de enquadramento legal nas condi??es de en-saio. Pesaram-se os adsorventes antes e ap?s o tratamento para obten??o da impregna??o de ?leo, meta de desempenho da a??o vibrat?ria e tratamento como um todo. Tecnologias atuais de tratamento s?o referenciadas para compara??o de desempenho, qualitativa e quantitativa-mente. Confrontou-se consumo energ?tico operando-se em vibra??o, com e sem flota??o con-vencional, e com autoflota??o. Vislumbram-se boas perspectivas de rendimento do sistema proposto, sobretudo, na redu??o do tempo de resid?ncia por a??o de capilaridade. Criou-se o par?metro adimensional de impregna??o e se lhe confrontou com consagrados par?metros a-dimensionais, na vers?o vibracional, como n?mero de Weber e n?mero de Froud quadr?tico, referido como criticalidade vibr?til. Resultados sugerem limites ? intensidade vibrat?ria
