- Core muscles activity levels during lumbar stabilization exercisesPublication . Ramos, Inês Oliveira; Vilas Boas, Joana; Branco, Sofia; Pereira, Ana; Carvalho, Paulo; Santos, RubimThis study examined the muscle activity levels of abdominal and back muscles while subjects performed specific exercises for lumbar stabilization training with abdominal bracing and drawing-in.
- The influence of upper limb bilateral flexion on thoracic extensors strength and muscular activityPublication . Magina, V.H.; Melo, Cristina; Carvalho, Paulo; Barbosa, P.; Moreira, C.; Santos, RubimThe main objective of this study was to verify the effect of a bilateral upper limb flexion exercise (180◦gleno-humeral flexion, with straight elbows) with isometric contraction at the end of the range of motion, on the thoracic extensors strength and muscle activity.
- Activation timings of the scapular stabilizers in subjects with a stroke affecting the right versus left hemispheresPublication . Ferreira, S.; Silva, Cláudia; Silva, A.; Carvalho, Paulo; Santos, RubimLesions affecting the right hemisphere influence the ability to plan the virtual reaching trajectory and, consequently the postural control. On the other hand, left hemisphere lesions affect the ability to select the adequate motor program to reach the target. This study aimed to explore the existence of differences at the activation timings and sequence of activation of the scapular stabilizers, mainly the serratus anterior, superior, middle and inferior trapezius fibers, in relation to the anterior deltoid, in subjects with a stroke affecting the right versus left hemispheres, during reaching. Besides, it aimed to establish comparisons between both sides of each subject and a group of subjects without of each subject and a group of subjects without pathology.
- Effects of low doses of external radiation from 137Cs on Lactuca sativa seedling and Daphnia magna reproductionPublication . Teles, Luís; Henriques, Marta; Santos, Rubim; Barros, PiedadeNaturally occurring cesium exists as a stable isotope 133Cs in the earth crust in granites and in sedimentary rocks. Cesium has very low mobility in soil surfaces.
- Comparing the effects of two different intervention programs on the level of axiety and depression in elderly individualsPublication . Silva, Ana Sofia; Oliveira, Bibiana; Matos, Paula; Lopes, Daniela; Portugal, Paula; Coelho, Tiago; Fernandes, Ângela; Santos, RubimThroughout the process of aging, there are several changes that can cause postural instability or balance disability, increasing the number of fall in elderly.
- Comparing the effects of two different intervention programs on mobility, balance and risk of falls in elderly individualsPublication . Azevedo, Ricardo; Oliveira, Bibiana; Silva, Ana Sofia; Matos, Paula; Coelho, Tiago; Fernandes, Ângela; Santos, Rubim; Portugal, PaulaMobility and balance impairments are frequent in old age. Consequently, elderly individuals may present a higher risk of falling, which in turn can have dire consequences.
- The Alqueva hydro-meteorologic experimentPublication . Salgado, R.; Potes, M.; Albino, A.; Apolinário, J.; Barbosa, S.; Bárias, S.; Beliche, P.; Bortoli, D.; Canhoto, P.; Costa, M. J.; Fernandes, R.M.; Harrison, G. G.; Ilhéu, A.; Le Moigne, P.; Lima, Raúl; Lopes, F.; Lopes, T.; Marques, J.; Melgão, M.; Miranda, P. M.; Morais, M.; Murteira, M.; Nicoll, K.; Novais, M. H.; Nunes, S.; Parrondo, M. C.; Penha, A.; Pereira, S.; Policarpo, C.; Prior, V.; Rodrigues, C. M.; Rosado, J.; Sá, A.; Serafim, A.; Silva, H.; Soares, P. M. M.; Tlemçani, M.; Zavattieri, A.The ALqueva hydro-meteorological experiment, ALEX 2014 (http://www.alex2014.cge.uevora.pt) was an integrated field campaign with measurements of chemical, physical and biological parameters at different experimental sites in the Alqueva reservoir and in its surrounding region. With the main purpose of studing the lake-atmosphere interactions, the ALEX 2014 took place form June to September and comprised a three days Intensive Observation Period (IOP) from 22 to 24 July.
- Interactions lake-atmosphere: the ALEX 2014 field campaign and numerical simulationsPublication . Salgado, R.; Potes, M.; Albino, A.; Apolinário, J.; Barbosa, S.; Bárias, S.; Beliche, P.; Bortoli, D.; Canhoto, P.; Costa, M. J.; Fernandes, R.M.; Harrison, G.; Ilhéu, A.; Le Moigne, P.; Lima, Raúl; Lopes, F.; Lopes, T.; Marques, J.; Melgão, M.; Miranda, P. M.; Morais, M.; Murteira, M.; Nicoll, K.; Novais, M.

M.; Tlemçani, M.; Zavattieri, A.The ALqueva hydro-meteorological EXperiment, ALEX 2014, was an integrated field campaign with measurements of chemical, physical and biological parameters in water and air at different experimental sites in the region of the Alqueva reservoir, a 250 km2 man made lake, in the southeast of Portugal. The Field campaign took place from June 1 to September 30, 2014 and comprises an Intensive Observation Period (IOP) of three days (22 to 24 July). During the four months, the over water fluxes of momentum, heat and mass (H2O and CO2) were obtained with an integrated Open-Path CO2 /H2O Gas Analyser and 3D Sonic Anemometer, mounted on a floating platform, where radiative fluxes were also measured, as well as the water temperature profile. Eight near surface weather stations were operating in the area and air quality, atmospheric electrical field (Potential Gradient) and radon (222Rn) concentration were continuous monitored. Along this period, in situ measurements, water samples and biological elements were monthly collected from three fixed platforms placed in the lacustrine zone and from selected sites in the margins. During the IOP, radiosondes were launched every tree hours, allowing a characterization of the atmospheric boundary layer and its evolution. In 10 occasions Geigersondes were coupled to the radiosondes in order to obtain the atmospheric ionization profile. The boundary layer was characterized with a Ceilometer and the vertical distribution of O3 and NO2 were obtained from a Spectrometer. A GPS network of 15 GNSS stations was installed in order to map the water vapour. The sky brightnesson the nights of July 24 and 25, was measured using a Sky Quality Meter. The lake-atmosphere interactions and its impact in the boundary layer structure and in the local circulations are studied using data collected during the ALEX 2014 POI together with results from numerical simulations performed with the non-hydrostatic Meso-NH french model.
- Coincidence detection in PETPublication . Clemêncio, Filomena; Landeck, JorgeA complex task for PET cameras is the design of a coincidence detection system that allows for a very tight time window. This brings us necessarily to discussing the concept of coincidence in PET (including the concepts of single, prompt and multiple events in a PET chamber), the different options for coincidence sorting and the concept of Field of View (FOV). We present results from a coincidence system we implemented in a Xilinx Virtex-5 FPGA with coincidence time windows of the order of a few hundred picoseconds and capable of FOV selection and multiple coincidence rejection implemented in real-time.
- The effects of anxiety symptoms on postural stability in young adultsPublication . Matos, Paula; Silva, Ana Sofia; Oliveira, Bibiana; Azevedo, Ricardo; Coelho, Tiago; Lopes, Daniela; Fernandes, Ângela; Santos, RubimAnxiety is defined as a state or an emotional response. When excessive or prolonged may be reflected in thinking, behavior and motor skills, such as postural stability. To compare the population with and without anxiety symptoms in relation to postural stability on orthostatic position.
