Non destructive evaluation of plasters on historical thin vaults by scanning laser Doppler vibrometers was attempted in this article. The aim was to investigate the state of conservation of historical plasters hanged from thin light vaults made by plaster and reeds that often carried on their lower surface frescoes and stuccos of high historical, artistic and architectural value. SLDV could represent an effective support for the diagnostic process of these construction system. In particular, the first results underline that processing the data so asto estimate the so-called Operational Deflection Shapes (ODS)does not seem to be helpful as a damage indicator, on the contrary modal analysis seems to be effective in localizing damages present in the specimen. KEYWORDS: thin vaults; SLDV; historical plaster; NTD; diagnostic of cultural heritage; plaster and reeds vaults.
Background: Over the past few decades, critical care has seen many advancements. These advancements resulted in a considerable increase in the prevalence of chronically critically ill patients requiring prolonged medical care, which led to a massive increase in healthcare utilization. Methods: We performed a search for suitable articles using PubMed and Google Scholar from the inception of these databases to 15 May 2021. Results: Thirty-four articles were included in the review and analyzed. We described the following characteristics and problems with chronic critically ill patient management: the patient population, remote monitoring, the monitoring of physiological parameters in chronic critically ill patients, the anatomical location of sensors, the barriers to implementation, and the main technology-related issues. The main challenges in the management of these patients are (1) the shortage of caretakers, (2) the periodicity of vital function monitoring (e.g., episodic measuring of blood pressure leads to missing important critical events such as hypertension, hypotension, and hypoxia), and (3) failure to catch and manage critical physiological events at the right time, which can result in poor outcomes. Conclusions: The prevalence of critically ill patients is expected to grow. Technical solutions can greatly assist medical personnel and caregivers. Wearable devices can be used to monitor blood pressure, heart rate, pulse, respiratory rate, blood oxygen saturation, metabolism, and central nervous system function. The most important points that should be addressed in future studies are the performance of the remote monitoring systems, safety, clinical and economic outcomes, as well as the acceptance of the devices by patients, caretakers, and healthcare professionals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
