    Coronavirus disease 2019 (COVID-19) is the pandemic challenge striking many health systems worldwide. The new coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2), which has a well-known tropism to lung cells, is the cause

    Full-Aeroelastic Model of CAARC Building: Iterative Design Procedure and Wind Tunnel Tests

    No full text
    A first step of a broader framework, concerning the investigation of tall buildings’ dynamic response to wind load, is presented. In order to accomplish this challenging task, a well-known benchmark has been selected: the CAARC (Commonwealth Advisory Aeronautical Research Council) standard tall building. Decades of literatures on the subject make it the perfect candidate to tackle the complexity of wind-structure interaction phenomena. The present work concerns the design of a full-aeroelastic multi degrees of freedom model. The configuration proposed by J. Holmes at International Conference on Wind Engineering (2007), accounting for both flexural and torsional decoupled modes of vibrations, is adopted. A design theory present in literature is re-proposed, from a different prospective, in a semi-automated fashion through a Python script. At last, preliminary results are shown, demonstrating the method’s efficiency and applicability, not only to tall buildings, but more generally to structures with continuous distribution of mass

    Exercise Training and Rehabilitation in Pulmonary Hypertension

    Within the last years, exercise training and rehabilitation as add-on to medical treatment has become an emerging field in pulmonary hypertension. Owing to the beneficial effects of exercise training in pulmonary hypertension, the new European Respiratory Society/European Society of Cardiology guidelines for pulmonary hypertension recommended a supervised and closely monitored exercise and respiratory training/rehabilitation as add-on to medical therapy (class IIa, level of evidence B). In this article, different training modalities, effects of exercise training, possible pathobiological mechanisms of action, and future research questions are discussed
