O presente trabalho tem como objetivo a caracteriza??o dos padr?es de movimenta??o em fina escala dos machos cantores de Jubarte em um s?tio reprodutivo para detectar efeitos da abund?ncia de machos cantores e da presen?a de embarca??es. Adicionalmente, buscou-se verificar se ? poss?vel fazer infer?ncias sobre os estados comportamentais dos cantores atrav?s das suas trajet?rias. A coleta dos dados foi feita utilizando-se arranjos de gravadores ac?sticos aut?nomos desenvolvidos pelo Programa de Pesquisas em Bioac?stica da Universidade de Cornell - EUA. O estudo foi realizado no s?tio reprodutivo das baleias Jubarte do Pac?fico Sul Ocidental localizado no Banco dos Abrolhos-BA durante a temporada reprodutiva de 2005. Os machos cantores de Jubarte foram identificados atrav?s da detec??o dos seus sons por meio da inspe??o visual dos espectrogramas das grava??es. As posi??es dos cantores foram estimadas atrav?s da localiza??o de cada som identificado com boa qualidade em pelo menos 3 dos 5 canais de ?udio atrav?s de algoritmo customizado em ambiente MATLAB. Da mesma forma foi realizada a detec??o dos eventos de embarca??es. As trajet?rias foram constru?das a partir dos pontos de localiza??o ap?s uso do filtro Kalman. As trajet?rias foram classificadas em categorias de abund?ncia de cantores (baixa = at? dois cantores e alta = a partir de tr?s cantores) e de presen?a de barco (presen?a e aus?ncia). Fun??es de distribui??o de probabilidade foram constru?das a fim de testarmos, por meio da an?lise de m?xima verossimilhan?a, qual distribui??o se ajustaria melhor aos nossos dados. Foi feita uma sele??o de modelos concorrentes incluindo como modelos as categorias de an?lise (abund?ncia e presen?a de barcos) e as fun??es de distribui??o ajustadas aos dados. A vari?vel preditora utilizada foi a velocidade. O melhor modelo foi escolhido com o Crit?rio de Informa??o de Akaike corrigido para pequenas amostras (AICc). Os padr?es de movimenta??o descritos diferiram de estudos pr?vios. Nossas categorias de an?lise n?o se mostraram boas para a explicar a varia??o dos dados, mas os modelos foram capazes de identificar dois padr?es distintos de movimenta??o de machos cantores de jubarte: passos lentos e constantes caracterizando um estado comportamental explorat?rio intercalados por raros passos r?pidos que caracterizam um movimento direcional. As motiva??es para a altern?ncia entre os diferentes estados comportamentais provavelmente envolvem diferentes estrat?gias reprodutivas. Nossos resultados mostraram que trajet?rias baseadas em dados ac?sticos podem ser utilizadas para a infer?ncia de estados comportamentais distintos de baleias jubarte atrav?s da an?lise dos padr?es de movimenta??o. / Studies on movement may provide various types of information on the ecology of different animal groups, from perception and habitat use to inferences on behavioral states. This study aims to characterize movement patterns in thin range of male humpback singers at a reproductive site and to detect effects of singing males abundancy and presence of vessels. Additionally, we verified if it is possible the inference of different behavioral states of singer males through their trajectory. Data collection was done using arrangements of autonomous acoustic recorders developed by the Bioacoustics Research Program of Cornell University ? EUA. The study was conducted at the reproductive site of the humpback whales from the Western South Pacific, located at the Abrolhos Bank, state of Bahia, Brazil, during the reproductive season of 2005. Singing humpback males were identified through the detection of their sounds by visual inspection of the recording spectrograms. Singers positions were estimated through location of each sound identified with good quality in at least three of five audio channels through a custom algorithm in a MATLAB environment. Detection of vessels events was done the same way. Trajectories were built from location points after using the Kalman filter. Trajectories were arranged in categories such as singers abundancy (low = up to two singers and high = from three singers on) and vessel presence (presence and absence). Functions of probability distribution were built for us to test, by likelihood analysis, which distribution adjusts better to our data. A selection of competing models was done, including as models analysis categories (abundancy and presence of vessels) and distribution functions adjusted to our data. The predictor variable used was speed of each step. The best model was selected with Akaike?s Information Criterion corrected for small samples (AICc). Movement patterns described differed from previous studies. Our analysis categories were not good to explain data variation, but models were capable of identifying two distinct movement patterns of humpback male singers: slow and constant steps characterizing an exploratory behavioral state interpolated by rare fast steps which characterize a directional movement. Motivations for variation between different behavioral states probably involve different reproductive strategies. Our results showed that trajectory based on acoustic data can be used to infer distinct behavioral states o humpback whales through the analysis of movement patterns.

Ten genera historically included in the tribe are assumed as ingroup in the present analysis, which comprises: Aposturisoma, Cteniloricaria, Farlowella, Harttia, Harttiella, Lamontichthys, Metaloricaria, Pterosturisoma, Sturisoma and Sturisomatichthys. The ingroup encompasses 78 terminal taxa plus 22 belonging to the outgroup which were chosen from other subfamilies of the Loricariidae and genera of the Loricariini. Seven molecular markers were included for the phylogenetic analysis, the mitochondrial Cytb, nd2, 12S and 16S, and the nuclear MyH6, RAG1 and RAG2. Additionally, 216 morphological characters are included, which encompasses characters proposed by previous authors and new characters proposed herein including both osteology and external morphology. A Maximum Parsimony analysis and a Bayesian Inference analyses were carried out using the concatenated matrix which is comprised by 6,839 characters. Thirty most parsimonious trees were found with a length of 18.254 steps, consistency index (CI) of 0.37 and retention index (RI) of 0.59, a consensus tree was obtained and showed a paraphyletic Harttiini sensu Isbr?cker; the same result was obtained from the Bayesian Inference analysis. Harttiini comprises Harttia, Harttiella and Cteniloricaria. Farlowellina is elevated to the tribe rank as Farlowellini, encompassing Farlowella, Lamontichthys, Pterosturisoma, Sturisoma and Sturisomatichthys; Aposturisoma is here suggested as junior synonym of Farlowella. Metaloricaria is assigned to the monotypic Metaloricariini. On the other hand, the Loricariini is here restricted to a unique group without a subtribal division, contrary to what was proposed in previous studies. Sturisoma was corroborated here to be strictly cis-Andean, while Sturisomatichthys encompasses, besides the valid species already included in the genus, the trans-Andean species belonging to Sturisoma sensu lato. Two new species of the former and one new species of the latter were recognized. A new classification for the Loricariinae is offered, as well as for identification keys for the genera of both the Harttiini and the Farlowellini. Discussions regarding the taxonomy of the genera found to be valid are offered. Furthermore, a taxonomic revision of Sturisomatichthys is presented. A total of 358 specimens including both type an non-type specimens of all valid species were examined. Sturisomatichthys was found to encompass 12 valid species: Sturisomatichthys aureus, S. caquetae, S. citurensis, S. dariensis, S. festivus, S. frenatus, S. kneri, S. leightoni, S. panamensis, S. tamanae. In addition, two new species are described, Sturisomatichthys Baud? n.sp. from the Baud? River, in Northwestern Colombia, belonging to the Caribbean slope of the continent, and Sturisomatichthys San Juan n.sp. from the San Juan River basin in western Colombia, on the Pacific slope. Sturisomatichthys caquetae, from the Morelia River, upper Amazon, is transferred back from Sturisoma and S. leightoni is distributed, besides the Magdalena-Cauca basin, in the Orinoco basin; thus, Sturisomatichthys is discovered to be distributed in both trans- and cis-Andean drainages. A neotype is designated for S. aureus from the Lower Magdalena basin, type locality of the species. New records of localities in the Northwestern region of South America, as well as the redescription and taxonomic comments of all valid species, are provided. Maps with the distribution of the genus and a key of identification of the species are provided. / Uma an?lise de evid?ncia total de Harttiini sensu Isbr?cker ? apresentada.

Among the renewable energy sources, solar energy is the most promising, presenting technology of greatest growth rate nowadays. Researchers around the world are seeking ways to facilitate their progress, developing technologies with higher efficiency and lower cost. As a contribution to global progress, this master thesis proposes the development of a strategy of maximum power tracking based on perturbation and observation method for photovoltaic systems. The proposed control strategy is based on active power balance of the system, with a reduced number of sensors. It also allows the PV system to act as a regulator of the power quality at the point of commom coupling (PCC), compensating the harmonic distortion and power factor of the current netw / A escassez dos recursos naturais e a busca por fontes de energia alternativa promovem uma r?pidamudan?a namatriz energ?tica mundial.

Nosso interesse por esse vi?s se deu a partir da po?tica fragment?ria do Livro do desassossego, composto por Bernardo Soares, ajudante de guardalivros na cidade de Lisboa e semi-heter?nimo do escritor Fernando Pessoa. Nossa abordagem acerca desse g?nero textual partir? de uma metodologia comparativa, a qual nos possibilite norteamentos, para que possamos estabelecer algumas rela??es de semelhan?as e diferen?as entre fragmentos, m?ximas, aforismos e reflex?es, cujo corpus liter?rio ser? o di?rio ?ntimo do desassossego soariano, bem como a pr?pria fragmenta??o do simulacro de autor no decorrer dos anos em que o Livro foi escrito. O Livro do desassossego lan?a pulveriza??es reflexivas, as quais permanecem atuais, posto que, o processo da escritura fragment?ria parece estar sempre num movimento cont?nuo e, portanto, no ambiente do porvir. Da? enfrentarmos certos obst?culos ao tentar estabelecer uma defini??o para o que vem a ser a escritura fragment?ria. Logo, buscaremos pontos de interse??es visando a estabelecer algum paradigma, para alcan?armos no??es mais delimitadas acerca desse g?nero textual, envolvendo m?ximas, aforismos e senten?as reflexivas.

Being addressed the following techniques: Moments (moments), Maximum Likelihood (MLE), Biased Probability Weighted Moments (PWMB), Unbiased Probability Weighted Moments (PWMU), Mean Power Density Divergence (MDPD), Median (MED), Pickands (PICKANDS), Maximum Penalized Likelihood (MPLE), Maximum Goodness-of-fit (MGF) and the Maximum Entropy (POME) technique, the focus of this manuscript. By way of illustration adjustments were made for the Generalized Pareto distribution, for a sequence of earthquakes intraplacas which occurred in the city of Jo?o C?mara in the northeastern region of Brazil, which was monitored continuously for two years (1987 and 1988). It was found that the MLE and POME were the most efficient methods, giving them basically mean squared errors. Based on the threshold of 1.5 degrees was estimated the seismic risk for the city, and estimated the level of return to earthquakes of intensity 1.5?, 2.0?, 2.5?, 3.0? and the most intense earthquake never registered in the city, which occurred in November 1986 with magnitude of about 5.2? / O objetivo desse trabalho ? fazer uma breve discuss?o dos m?todos de estima??o dos par?metros da distribui??o generalizada de Pareto (GPD).

It has two forms: type 1 (DM1 or Steinert's disease); and type 2 (DM2), being the former the most frequent and showing systemic manifestations, such as myotonia (muscle relaxation difficulty), cataracts, arrhythmias, muscle weakness and atrophy, among others, respiratory failure being one of the main factors predictive of mortality and a leading cause of death. OBJECTIVES: To evaluate the sensitivity / specificity of the maximum relaxation rate of the inspiratory muscles (MRR), the surface electromyography (sEMG) of the sternocleidomastoid (SCM), scalene (SCA), parasternal (2ICS), rectus abdominis (RA) and lung function/respiratory muscle strength in patients with DM1 and healthy subjects. METHODS: We invited 74 subjects to participate in the study, 44 patients with DM1 and 30 controls. The study included 31 subjects (18 DM1 and 13 controls). After exclusions, the final sample was of 27 subjects, 16 patients with DM1 and 11 healthy subjects. All of them were assessed for MRR of inspiratory muscles, for sEMG of the respiratory muscles, muscle and lung function. RESULTS: The MRR was lower in patients with DM1 vs. control (p = 0.001) and was considered sensitive and specific to identify the disease in DM1 and discard it in the control group, ROC area of 0.87 (95% CI, 0.74 to 1.01, p=0.001). DM1 group showed lower PImax (p=0.0006), PEmax (p=0.0002), SNIP (p=0.0014), CVF%pred (p=0.0018) and FEV1%pred. (p=0.0004) and higher sEMG activity of the SCM (p=0.0022) and ESC muscles (p=0.004) at rest; of 2EIC (p=0.003) during PEmax and of SCM (p=0.02) and ESC muscles (p= 0.03) during the sniff test. CONCLUSIONS: The MRR is sensitive and specific to identify delayed relaxation of the respiratory muscles and respiratory muscle function is altered in patients with DM1.

Os dados utilizados neste estudo foram obtidos nas idades 27, 40, 50, 61, 76, 87, 101, 112, 122, 137, 147, 158 e 165 meses. Esse povoamento foi submetido a tratamentos de remo??o seletiva de 20%, 35% e 50%, nas idades 58 e 142 meses. Utilizou-se dois modelos de distribui??o diam?trica, empregando bases de dados observadas aos 27 meses (antes do primeiro desbaste), aos 61 meses (ap?s o primeiro desbaste) e aos 147 meses (ap?s o segundo desbaste). Por meio dos modelos gerou-se tr?s sistemas, os quais se diferiram no m?todo de ajuste da fun??o Weibull. No sistema 1 os par?metros da fun??o Weibull foram ajustados pelo m?todo de aproxima??o linear. No sistema 2 e no sistema 3, os par?metros foram ajustados pelo m?todo da m?xima verossimilhan?a. As proje??es realizadas pelos sistemas foram confrontadas com as distribui??es diam?tricas observadas, por meio do teste de ader?ncia Kolmogorov-Smirnov a 1% de signific?ncia, e pelo teste F de Graybill, com n?vel de signific?ncia de 5%. Os tr?s sistemas proporcionaram distribui??es diam?tricas projetadas estatisticamente semelhantes ?s observadas, antes e ap?s o desbastes. O sistema 2 apresentou um maior percentual de proje??es n?o significativas para os dois testes estat?sticos empregados. As simula??es realizadas pelos modelos apresentaram realismo estat?stico e tend?ncia do crescimento da distribui??o de di?metros para diferentes porcentagens de desbaste. Houve maior efici?ncia dos modelos ao se utilizar distribui??es diam?tricas observadas em idades imediatamente antes do desbaste. As proje??es das distribui??es diam?tricas, empregando-se como base inicial as distribui??es observadas antes do primeiro desbaste e imediatamente ap?s os desbastes (simula??es 1, 2 e 3), foram mais precisas do que as proje??es obtidas quando foram utilizadas somente as distribui??es diam?tricas observadas antes do primeiro desbaste como base inicial para as proje??es e, em seguida, simulados os desbastes nas idades previstas e, por ?ltimo, realizadas as proje??es empregando-se a distribui??o estimada remanescente do desbaste como base inicial para projetar as distribui??es para idades subsequentes (simula??es 4, 5 e 6). / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / The objective of the study was evaluated from the statistical and biological point of view, simulations performed by two models of diametric distribution, adjusted by linear approximation and maximum likelihood methods, in eucalyptus plantations submitted to thinning. The data were found in a hybrid settlement of Eucalyptus grandis x Eucalyptus urophylla, under thinning regime, located in the northeast region of Bahia, linked to the company BAHIA ESPECIALIDADE CELULOSE. The data used in this study 27, 40, 50, 61, 76, 87, 101, 112, 122, 137, 147, 158 and 165 months. This population was submitted to treatments of selective removal of 20%, 35% and 50%, in the ages 58 and 142 months. Two diametric distribution models were used, using data bases observed at 27 months (before the first thinning), at 61 months (after the first thinning) and at 147 months (after the second thinning). By means of the models three systems were generated, the channels did not differ any method of adjustment of the Weibull function. No system 1 of the Weibull function parameters were adjusted by the linear approximation method. In system 2 and in system 3 the parameters were adjusted by the maximum likelihood method. As the projections performed by the systems were compared with the observed diametric distributions, using the Kolmogorov-Smirnov test at 1% significance, by the Graybill F test, with a significance level of 5%. The three systems provided by the statistically projected diametric distributions for observations, before and after the deviations. System 2 presents a higher percentage of nonsignificant projections for the two statistical tests used. As simulations of model execution demonstrated statistical realism and tendency of growth of the distribution of diameters for different percentages of thinning. There was greater efficiency of the models of use of diametric distributions observed in ages before thinning. As the projections of the diametric distributions, using as an initial basis as distributions observed before the first thinning and after the slabs (simulations 1, 2 and 3), were more accurate than the projections obtained when only diametric distributions observed before the first Thinning as the initial basis for the projections and then simulated the lagging at the predicted ages and finally performed as projections using an estimated remnant distribution of the thinning as the initial basis for designing as distributions for subsequent ages (simulations 4, 5 and 6).

Objectives: To evaluate the influence of obesity in the movement of thoracoabdominal complex at rest and during maximal voluntary ventilation (MVV), and the contribution between the different compartments of this complex and the volume changes of chest wall between obese and non-obese patients. Materials and Methods: We studied 16 patients divided into two groups: the obese group (n = 8) and group non-obese (n = 8). The two groups were homogeneous in terms of spirometric characteristics (FVC mean: 4.97 ? 0.6 L - 92.91 ? 10.17% predicted, and 4.52 ? 0.6 L - 93.59 ? 8.05%), age 25.6 ? 5.0 and 26.8 ? 4.9 years, in non-obese and obese respectively. BMI was 24.93 ? 3.0 and 39.18 ? 4.3 kg/m2 in the groups investigated. All subjects performed breathing calm and slow and maneuver MVV, during registration for optoelectronic plethysmography. Statistical analysis: we used the unpaired t test and Mann-Whitney. Results: Obese individuals had a lower percentage contribution of the rib cage abdominal (RCa) during breathing at rest and VVM. The variation of end expiratory (EELV) and end inspiratory (EILV) lung volumes were lower in obese subjects. It has been found asynchrony and higher distortion between compartments of thoracoabdominal complex in obese subjects when compared to non-obese. Conclusions: Central obesity impairs the ventilation lung, reducing to adaptation efforts and increasing the ventilatory work / Contextualiza??o: A obesidade pode afetar o sistema respirat?rio, causando altera??es na mec?nica ventilat?ria, nos volumes e fluxos pulmonares. Objetivos: Avaliar a influ?ncia da obesidade no movimento do complexo t?raco-abdominal durante o repouso e durante a ventila??o volunt?ria m?xima (VVM), assim como a contribui??o entre os diferentes compartimentos desse complexo e as varia??es de volume da parede tor?cica e entre obesos e n?o obesos. Materiais e M?todos: Foram avaliados 16 indiv?duos divididos em dois grupos: grupo de obesos (n = 8) e grupo de eutr?ficos (n = 8). Os dois grupos foram homog?neos quanto ?s caracter?sticas espirom?tricas (m?dia de CVF: 4,97 ? 0,6 L 92,91 ? 10,17 % do predito, e 4,52 ? 0,6 L 93,59 ? 8,05 %), idade 25,6 ? 5,0 e 26,8 ? 4,9 anos, em eutr?ficos e obesos respectivamente. O IMC foi de 24,93 ? 3,0 e 39,18 ? 4,3 kg/m2, nos grupos investigados. Todos os sujeitos realizaram respira??o calma e lenta e a manobra de Ventila??o volunt?ria m?xima, durante o registro por pletismografia optoeletr?nica. Para an?lise estat?stica, foram utilizados os testes t n?o pareado e de Mann-Whitney. Resultados: Os indiv?duos obesos apresentaram menor contribui??o percentual da caixa tor?cica abdominal (RCa) durante a respira??o em repouso e na VVM. A varia??o dos volumes pulmonares expirat?rio (VEE) e inspirat?rio finais (VEI) foram menores nos sujeitos obesos. Foram constatados maiores assincronia e distor??o entre os compartimentos do complexo t?raco-abdominal nos obesos, quando comparados aos eutr?ficos. Conclus?es: A obesidade central interfere negativamente na ventila??o pulmonar, reduzindo a adapta??o aos esfor?os e incrementando o trabalho ventilat?rio

This study aimed to evaluate the feasibility of adapting a national electronic manovacuometer to measure the nasal inspiratory pressure (study 1) and analyze the level of load intensity of maximum voluntary ventilation, as well as the variables that may influence this maneuver in healthy subjects (study 2). We studied 20 healthy subjects by a random evaluation of two measures of SNIP in different equipments: a national and an imported. In study 2 it was analyzed the intensity of the load of MVV test, change in pressure developed during the maneuver, the possible differences between genders, and the correlations between the flow developed in the test and the result of MVV. In study 1 it was found the average for both measures of nasal inspiratory pressures: 125 ? 42.4 cmH2O for the imported equipment and 131.7 ? 28.7 cmH2O for the national one. Pearson analysis showed a significant correlation between the average, with a coefficient r = 0.63. The average values showed no significant differences evaluated by paired t test (p> 0.05). In the Bland-Altman analysis it was found a BIAS = 7 cmH2O, SD 32.9 and a confidence interval of - 57.5 cmH2O up to 71.5 cmH2O. In the second study it was found significant differences between the genders in the air volume moved, being higher in males 150.9 ? 13.1 l / min vs 118.5 ? 15.7 L / min for (p = 0.0002, 95% CI 44.85 to 20:05). Regarding the inspiratory and expiratory loading, they were significantly higher in men than in women, peak inspiratory pressure (34.7 ? 5.3 cmH2O vs 19.5 ? 4.2 cmH2O, 95% CI - 18.0 to -12.3, p <0.0001), peak expiratory (33.8 vs. 23.1 ? 5.9 cmH2O ? 5.4 cmH2O, 95% CI -17.1 to - 4.6, p <0.0001), and the delta pressure (59.7 ? 10 cmH2O vs 36.8 ? 8.3 cmH2O, 95% CI 14.5 to 31.2, p <0.0002). The Pearson correlation showed that the flow generated by the maneuver is strongly correlated with the delta-expiratory pressure / inspiratory (r2= 0.83,R = 0.91, 95%IC 0.72 a 0.97 e p< 0.0001).Through these results we suggest that the national electronic manovacuometer is feasible and safe to perform the sniff test in healthy subjects. For the MVV, there are differences between the genders in the intensity of pressure developed during the maneuver. We found a load intensity considered low during the MVV, and found a strong correlation between the flow generated in the test and the delta pressure expiratory / inspiratory / A import?ncia clinica de avaliar os m?sculos respirat?rios com uma variedade de testes vem sendo proposta por diversos trabalhos, pois a combina??o de v?rios testes possibilitaria um melhor diagn?stico e consequentemente um melhor seguimento cl?nico das disfun??es dos m?sculos respirat?rios. Este trabalho teve como objetivo avaliar a viabilidade da adapta??o do manovacu?metro nacional eletr?nico para a realiza??o da medida de press?o inspirat?ria nasal (estudo 1) e analisar o n?vel de intensidade de carga da ventila??o volunt?ria m?xima, assim como as vari?veis que possam influenciar a manobra em sujeitos saud?veis (estudo 2). Foram estudados 20 sujeitos saud?veis atrav?s da avalia??o aleat?ria de duas medidas de SNIP em equipamentos diferentes: um nacional e outro importado. No estudo 2 foi analisado a intensidade da carga do teste da ventila??o volunt?ria m?xima(VVM), a varia??o de press?o desenvolvida durante manobra, as poss?veis diferen?as entre g?neros, e as correla??es entre o fluxo desenvolvido no teste e o resultado da VVM. No estudo 1 as m?dias encontradas durante as duas medidas das press?es nasais foram de 125 ? 42,4 cmH2O para o aparelho importado e de 131,7 ? 28,7 cmH2O para o nacional. A an?lise de Pearson demonstrou uma correla??o significativa entre as m?dias com um coeficiente r=0.63. Os valores m?dios n?o apresentaram diferen?as significativas avaliadas pelo teste t pareado (p>0,05).Na an?lise de Bland-Altman foi encontrado um BIAS igual a 7 cmH2O, desvio padr?o 32,9 e um intervalo de confian?a de - 57,5cmH2O at? 71,5 cmH2O. No estudo 2 foi encontrada diferen?a significativa entre os g?neros para o volume de ar deslocado maior em homens 150.9 ? 13.1 l/mim vs 118.5 ? 15.7 L/mim para (p= 0.0002, IC95% 20.05 ? 44.85). Em rela??o carga inspirat?ria e expirat?ria foram significativamente maiores em homens que nas mulheres: pico inspirat?rio (34.7 ? 5.3 cmH2O vs 19.5 ? 4.2 cmH2O, IC95% - 18.0 a -12.3, p< 0.0001), pico expirat?rio (33.8 ? 5.9 cmH2O vs 23.1 ? 5.4 cmH2O, IC95% -17.1 a - 4.6, p< 0.0001), assim como o delta de press?o (59.7 ? 10 cmH2O vs 36.8 ? 8.3 cmH2O, IC95% 14.5 a 31.2 , p< 0.0002). A correla??o de Pearson mostrou que o fluxo gerado pela manobra est? fortemente correlacionado com o delta de press?o expirat?ria/inspirat?ria (r2= 0.83,R = 0.91, (95%IC 0.72 a 0.97 e p< 0.0001). Atrav?s dos resultados encontrados podemos sugerir que o manovacu?metro eletr?nico nacional ? vi?vel e seguro para realiza??o do sniff teste em sujeitos saud?veis. Em rela??o a VVM, existem diferen?as entre os g?neros na intensidade de press?o desenvolvida durante a VVM, a uma intensidade de carga durante a VVM foi considerada baixa assim como foi encontrada uma forte correla??o entre o fluxo gerado no teste e o delta de press?o expirat?rio/inspirat?rio
