Acoustical performance of an innovative dry-wall facade system with high thermal properties

INTESA (INTegrazione ed elevata Efficienza con sistemi a Secco per l’Abitare, Integration and high efficiency with drywall technology for building envelopes) is an innovative solu-tion of a drywall façade embedding electrical, plumbing and HVAC systems, especially de-signed for residential needs. The INTESA system is usable either for new and retrofit design and is competitive with the traditional wet technology made of clay bricks or blocks. Since the early stage of the project, an integrated approach has been the key element to design the wall system in order to obtain an easy and efficient way of assembling, a perfect integration of the plants, as well as high thermal and acoustical performances. In-field INTESA perfor-mances were tested in laboratory and in a real case study through the construction of a proto-type building located in Calliano d’Asti, near Turin, where the following acoustical parame-ters were measured: the apparent sound reduction index (R’), the standardized sound level difference of a façade (D2m,nT) and the vibration sound reduction index (Kij), a quantity relat-ed to the vibrational power transmission over a junction between structural elements

INTESA System: A New High-performance and Highly Integrated Drywall Façade

INTESA is an innovative vertical envelope for residential, industrial and service tertiary buildings. It is a drywall façade system with high thermal and acoustic properties, embedding electrical and plumbing systems. The system was developed over two years by a multidisciplinary team, which involved researchers, manufacturers and consultants. An integrated approach has been the key element to design and prototype an innovative double cavity drywall façade, composed by plasterboard layers and blown-in cellulose flakes, with and without a thin layer of Phase Change Material. Thermal and acoustical properties have been optimized through laboratory measurements and simulations and later tested in a prototype building

WHO global research priorities for antimicrobial resistance in human health

The WHO research agenda for antimicrobial resistance (AMR) in human health has identified 40 research priorities to be addressed by the year 2030. These priorities focus on bacterial and fungal pathogens of crucial importance in addressing AMR, including drug-resistant pathogens causing tuberculosis. These research priorities encompass the entire people-centred journey, covering prevention, diagnosis, and treatment of antimicrobial-resistant infections, in addition to addressing the overarching knowledge gaps in AMR epidemiology, burden and drivers, policies and regulations, and awareness and education. The research priorities were identified through a multistage process, starting with a comprehensive scoping review of knowledge gaps, with expert inputs gathered through a survey and open call. The priority setting involved a rigorous modified Child Health and Nutrition Research Initiative approach, ensuring global representation and applicability of the findings. The ultimate goal of this research agenda is to encourage research and investment in the generation of evidence to better understand AMR dynamics and facilitate policy translation for reducing the burden and consequences of AMR
