O comportamento dos ajustes posturais antecipatórios na tibio-társica na sequência de levantar em indivíduos com doença de Parkinson

Introdução: A sequência de movimento de sentado para de pé (SPP) exige um elevado controlo postural (CP). Em indivíduos com doença de Parkinson (DP), os circuitos que envolvem os ajustes posturais antecipatórios (APA’s) parecem estar afetados, refletindo-se numa diminuição do CP com repercussões nesta sequência de movimento. Objetivo: Avaliar o comportamento dos APA’s na tibio-társica na sequência de movimento SPP em indivíduos com DP. Métodos: Recorreu-se ao estudo de 4 casos com DP, com tempo de evolução entre os 3 e 17 anos, objeto de uma intervenção de fisioterapia baseada nos princípios do Conceito de Bobath durante 12 semanas. Antes (M0) e após (M1) a intervenção procedeu-se ao registo eletromiográfico dos músculos tibial anterior (TA) e solear (SOL) bilateralmente e durante a sequência de SPP. Adicionalmente foram também utilizadas a Escala de Equilíbrio de Berg, a Modified Falls Efficacy Scale (MFES) e a Classificação Internacional de Funcionalidade (CIF), para, indiretamente, averiguar o impacto funcional da reorganização dos APA’s. Resultados: Em M0 os resultados sugerem uma diminuição APA’s, uma vez que se observou: 1) diferentes tempos de ativação do TA e do SOL entre membros e 2) uma ativação prévia do SOL ao TA para os participantes A, C e D. Em M1, observou-se uma aproximação ao comtemplado para os APA’s para a maioria dos indivíduos. Os resultados na escala de Berg e MFES, de M0 para M1, sugerem um aumento do equilíbrio e da capacidade de confiança na maioria dos participantes (A, 21/42 pontos, B manteve a pontuação final 31 pontos, C, 50/54 pontos e D 45/53 pontos na escala de Berg; A, 30/43 pontos, B, 21/18 pontos, C, 70/68 pontos e D, 40/64 pontos na MFES;). Também se observaram melhorias nas atividades e participação da CIF. Conclusão: nos indivíduos em estudo verificou-se, de uma forma geral, uma modificação no sentido da aproximação do período comtemplado para os APA’s, em M1. Nos sujeitos A, C, e D verificou-se uma modificação do tempo de activação do SOL em função da actividade do TA em M1. No individuo B, à esquerda não se verificou o mesmo comportamento, verificou-se a activação inversa do SOL ao TA.

Experimental study of proton induced nuclear reactions in 6,7 Li

This work presents the results of the experimental study of proton induced nuclear reactions in lithium, namely the 7Li(p,α) 4He, 6Li(p,α) 3He and 7Li(p,p)7Li reactions. The amount of 7Li and 6Li identified as primordial and observed in very old stars of the Milky Way galactic halo strongly deviates from the predictions of primordial nucleosynthesis and stellar evolution models which depend, among other factors, on the cross sections of reactions like 7Li(p,α) 4He and 6Li(p,α) 3He. These discrepancies have triggered a large amount of research in the fields of stellar evolution, cosmology, pre-galactic evolution and low energy nuclear reactions. Focusing on nuclear reactions, this work has measured the 7Li(p,α) 4He and 6Li(p,α) 3He reactions cross sections (expressed in terms of the astrophysical S -factor) with higher accuracy, and the electron screening effects in these reactions for different environments (insulators and metallic targets). The 7Li(p,α) 4He angular distributions were also measured. These measurementstook place in two laboratory facilities, in the framework of the LUNA (Laboratory for Undergroud Nuclear Astrophysics) international collaboration, namely the Laboratorio ´ de Feixe de Ioes ˜ in ITN (Instituto Tecnologico ´ e Nuclear) Sacavem, ´ Portugal, and the Dynamitron-TandemLaboratorium in Ruhr-Universitat¨ Bochum, Germany. The ITN target chamber was modified to measure these nuclear reactions, with the design and construction of new components, the addition of one turbomolecular pump and a cold finger. The 7Li(p,α) 4He and 6Li(p,α) 3He reactions were measured concurrently with seven and four targets, respectively. These targets were produced in order to obtain adequate and stable lithium depth profiles. In metallic environments, the measured electron screening potential energies are much higher than the predictions of atomic-physics models. The Debye screening model applied to the metallic conduction electrons is able to explain these high values. It is a simple model, but also very robust. Concerning primordial nucleosynthesis and stellar evolution models, these results are very important as they show that laboratory measurements are well controlled, and the model inputs from these cross sections are therefore correct. In this work the 7Li(p,p)7Li differential cross section was also measured, which is useful to describe the 7Li(p,α) 4He entrance channel.

Orbital forcing of stratal patterns in an inner platform carbonate sucession: an example from an Upper Hauterivian series of the Lusitanian Basin, Portugal

With an example taken from a late-Hauterivian series of the Lusitanian Basin (Portugal), we will demonstrate the sedimentary record of orbital pattern variations and, consequently, climate variations in an inner platform environment with patterns and isolation changes, allows us to establish 4 major orders of periodicity related to orbital components:- The large cycles ob bed thickness variation, constituted by 31-32 beds, recording the 400 ky eccentricity cycle component;- The medium cycles, represented by byndles of 8-9 beds, related to the 100 ky eccentricity cycle component; - The small cycles, of 3-5 beds, recording the 41 ky obliquity components;- The very small cycles, of 2 beds, related to the 22 ky and 26 ky precession components. The mean duration of each bed is around 11.8 ky, a number very close to that of the precession hemi-cycle. Climatic control on qualitative production is confirmed by the close relation between the bed thickness variations, the insolation variability and the variation of micritized elements concentrations.

Susceptibility of Biomphalaria tenagophila and Biomphalaria glabrata from the same region to two Brazilian strains of Schistosoma mansoni

B. tenagophila snails from Ouro Branco, MG, showed positivity for S. mansoni, with infection rates of 5%, 10%, (SJ strain), and 1% (LE strain) using a pool of miracidia. The mollusks were found to be susceptive from the 3rd generation reared in laboratory onwards. The B. tenagophila (OB, MG) when individually exposed to 10 miracidia, showed infection rate of 2% for LE strain. B. glabrata snails from Gagé, MG, showed a positivity rate of 58% for S. mansoni (LE strain), under experimental conditions. The B. tenagophila from Cabo Frio, RJ and B. glabrata from Belo Horizonte, MG used as a control for SJ strain showed infection rates of 47% - 85% and 36% respectivily. For the LE strain, B. glabrata (BH, MG) used as control showed infection rate of 40% - 75%.

The relationship of cardiorespiratory fitness, birth weight and parental BMI on adolescents’ obesity status

The aims of this study were as follows: (1) to analyze differences in cardiorespiratory fitness (CRF), parents' body mass index (BMI) and birth weight (BW) between non-overweight (NOW) and overweight/obese (OV/OB) adolescents, and (2) to investigate the association of those variables with the risk of their biological offspring being OV/OB. This study comprised 788 adolescents (477 girls and 311 boys), aged between 12 and 18 years. CRF was predicted by maximal multistage 20-m shuttle-run test according to the procedures described in FITNESSGRAM. Children's BMI was classified according to the International Obesity Task Force. Adolescents' BW was assessed from each child's pediatric record at birth. Parents' OV/OB status was defined and classified according to the World Health Organization. Socioeconomic status was defined by parental education. The prevalence OV/OB was 21.4 and 5.3%, respectively, and there were no gender differences. The OV/OB adolescents (girls and boys) had significantly (POB girls had one or two parents with OV/OB (POB compared with NOW. Girls with low CRF (OR: 2.66; POB (OR: 4.39; POB. Results from this study highlight the association between the family adolescents' obesity, in girls. Furthermore, our data suggested that low CRF and high BW were strong predictors of OV/OB in adolescence.

Epidemiologic studies of chagas' disease in the urban zone of Teresina. State of Piauí, northeastern Brazil

The triatomine species Rhodnius nasutus and Triatoma pseudomaculata were captured on palm trees Orbignya martiana "babaçu ", in the urban zone of Teresina. This kind of palm tree is largely distributed in Piauí State. The predominant species was R. nasutus; the young in stars predominated. The infestation index of palm trees and the infection index of triatomines by flagellates were 96.0 ana 29.1%, respectively. Marsupiais, bats and a rodent were captured in palm trees. The flagellates found in both triatomines ana marsupiais were morphologically and biologically indistinguishable from Trypanosoma cruzi. Forty seven percent (481/1,025) of triatomines were found concentrated in six palm trees where marsupiais circulated. Of the total of 1,025 triatomines 230 (22%) were infected by flagellates and 53.0% (123/230) of these infected triatomines were present in the same six palm trees. No evidence of triatomine domiciliation or human transmission was observed in the houses in the vicinity of palm trees. The results suggest that marsupiais play an important role in the life-cycle of T. cruzi in this region. The natural focus of Chagas' disease, demonstrated in the present study could represent a potential epidemiological threat.

Do Choupal até à Lapa. Etnografia do constructor da canção

Esta tese aborda a Canção de Coimbra no quadro dos estudos etnomusicológi-cos, tendo como principal objectivo a compreensão deste importante fenómeno en-quanto categoria musical autónoma. A construção dos padrões discursivos e performativos da Canção de Coimbra é alicerçada recorrendo a instrumentos tais como a etnografia da música e o estudo do dis-curso, exógeno e endógeno, sob o ponto de vista do método fenomenológico. Fenómeno musical performativo imerso num quadro simbólico particular, o ob-jecto de estudo apresenta-se como uma das manifestações mais ricas e exclusivas das comunidades escolares europeias, senão mundiais, privilegiando-se no ambiente de uma das mais antigas Universidades da Europa, com todos os rituais e simbolismos que o acompanham desde a fundação. O seu desenvolvimento incide fundamentalmente sobre a produção literária, a produção fonográfica, a participação musical directa, e o resultado de sessões de trabalho e entrevista com intérpretes, compositores e investigadores. O corpus principal do estudo organiza-se na observação do fenómeno Canção de Coimbra, em ligação directa com os seus contextos sociais e culturais, num período que decorre sobretudo entre ca. 1850 e a actualidade.

Hotel industry: An answer to the emerging trends on the global demand side of tourism

This dissertation studies essentially how Millennials are changing the hotel industry, in the sense that new trends are emerging with this generation and hotels need to respond accordingly, in order to survive within their competitive industry. Emphasis is also given to Asian travellers, as the enlargement of these countries’ middle class populations is predicted, therefore making Asian travellers a valuable target for the hotel industry. To successfully target this segment, hoteliers need also to consider the cultural differences and aspirations that come together with the Asian travellers, and appropriately adapt their offer to them. I will then redirect this study to the city of Lisbon, the Portuguese capital, to analyse if Lisbon’s four and five-star hotel managers are aware of the new market trends, and to understand how they are changing their hotels in order to make them more attractive to Millennials and Asian travellers. Using a sample of 12 hotels (four and five-stars ratings), I have concluded that, although there is a notable undergoing process of adaptation to these guests, there is a long way ahead in order for Lisbon’s hotels to entirely please and retain millennial guests.
