Abstract Paper degradation menaces the useful lifetime of books, manuscripts, and works on paper during storage, circulation, display in libraries, archives, museums. Severe damages such as embrittlement, decay, mold often occur to that might threaten lose cultural heritage. However, shelf life papers stored suitable conditions can be extended by hundreds years. The most important external fact...

Increasing usage of polymer composite materials necessitates the development recyclable alternatives to traditional thermoset matrices or new techniques for recycling these materials. One family promising are room temperature infusible acrylic resins, known commercially as Elium®. If be used in tidal stream energy and shipping sectors, they must able withstand long-term immersion seawater witho...

Mandibuloacral dysplasia (MAD) is a rare genetic condition characterized by bone abnormalities including localized osteolysis and generalized osteoporosis, skin pigmentation, lipodystrophic signs and mildly accelerated ageing. The molecular defects associated with MAD are mutations in LMNA or ZMPSTE24 (FACE1) gene, causing type A or type B MAD, respectively. Downstream of LMNA or ZMPSTE24 mutat...

This paper presents the results of comparative reliability study of C–V characteristics through three accelerated ageing tests for stress applied to an RF LDMOS: Thermal shock tests (TST, air–air test), thermal cycling tests (TCT, air–air test) and high temperature storage life (HTSL). The two first tests are carried out with a drain current flowing through the device during stress. The investi...
