Aerosol dispersion and deposition inside an idealized mouth-throat has been numerically simulated using a stochastic Lagrangian model accounting for Brownian motion particle-wall interaction. Delivery of nanoparticles to the lungs is extremely difficult, mainly due their low inertia, this reason they are often loaded into larger carrier particles. Bearing in mind potentialities advanced drug delivery, set monodisperse particles with diameters nanqsize range, as well respirable ranges, were...
This work presents and compares several cooperative navigation solutions for formations of autonomous underwater vehicles, equipped with depth sensors capable taking bearing measurements to their neighbors under a certain measurement topology. Two approaches based on the extended Kalman filter are described, one centralized other decentralized, which has advantage requiring much less communication computational complexity minimal degradation produced estimates. Additionally, four...
In this work, two cooperative navigation solutions based on the extended Kalman filter are described. One of these is a centralized solution and other fully decentralized, taking full advantage benefits that come with decentralization, such as scalability robustness. Simulations performed for formation autonomous underwater vehicles fixed measurement topology. The assumed to be equipped sensors allow them take measurements their depth bearing angles neighbors. Two different topologies...
Delivery of drugs to the lungs as aerosols is regarded an excellent route for local or systemic administration drugs. Aerosols have been used traditionally treating illnesses respiratory tract (e.g. asthma), but new perspectives and needs on inhalation therapy recently emerged insulin). The percentage drug that reaches targeted region, so-called respirable fraction (RF), in average only 30% dose provided patient. Thus, development more efficient formulations devices remains important issue.
The Ria Formosa, Southern Portugal (Algarve) is a mesotidal lagoon with restricted exchange Atlantic Ocean. Due to arid Mediterranean climate and absence of large freshwater inputs, the remains hypersaline relative adjacent ocean (≥37 psu). Generally, fecal coliforms land-derived bacteria do not survive long in seawater due UV, osmotic shock, oligotrophy competition marine bacteria. However, survival human pathogenic viruses natural waters relatively unknown. In view 2020–2021 SARS-CoV-2...
