- Automatic quality assessment of smart device microphone spirometryPublication . Pinho, B.; Almeida, R.; Jácome, C.; Teixeira, J. P.; Amaral, Rita; Lopes, F.; Jacinto, Tiago; Guedes, R.; Pereira, M.; Gonçalves, I.; Fonseca, J. A.; Amaral, RitaLung function tests are critical for diagnosis and monitoring of asthma and other respiratory diseases. Monitoring of lung function, in the absence of a healthcare professional, is very challenging but may be obtained through Smart Devices if automated quality assessment systems guarantee the proper technique during the forced expiratory manoeuvre. This paper describes the evaluation of one such system that uses the microphone of smart devices, regarding the initial effort of forced expiratory manoeuvres using the Back Extrapolated Volume. A health professional recorded microphone spirometry in 55 children (5-10 years), using a mobile game engineered for the purpose, and registered its quality. At least one acceptable manoeuvre was achieved for 96% of the children using a featured threshold. Using a stricter threshold of 5% of forced vital capacity, it was possible to ensure at least one acceptable manoeuvre for 69%. While the obtained results are comparable to findings in literature for regular spirometry in this age group, further work is required before we can determine whether the proposed algorithm is effective in real life.
- 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.

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.

M.; Ferreira, R.; Freitas, P.; Lopes, F.; Fonseca, J. AlmeidaAssessment of asthma control at every opportunity is recommended. Control of Allergic Rhinitis and Asthma Test (CARAT) is a patient reported outcome measure commonly used to assess asthma control in clinical practice.It includes ten questions answered in a 4 point Like rt scale that address upper and lower airway symptoms, sleep interference, limitation of activities , and the need to increase medication over a 4 week period. CARAT is frequently administered on paper during medical visits, but digital versions through website and mobile apps are available.
