Contribution Of Mechanical Tests: Assessing Vulnerability And Risks Of Degradation In Paintings
CeROArt : Conservation, Exposition, Restauration d'Objets d'Art, 2021 The conservation of paintings on canvas is closely associated with the understanding of their physico-mechanical properties. Using mechanical testing is essential when developing tools to assess the level of vulnerability and risks of mechanical ...

Methods for Measurement and Statistical Analysis of the Frangibility of Strengthened Glass
Frontiers in Materials, 2015 Chemically strengthened glass features a surface compression and a balancing central tension (CT) in the interior of the glass. A greater CT is usually associated with a higher level of stored elastic energy in the glass.

World Journal of Biological and Pharmaceutical Research, 2023 Word "pain" derives its origin from the Indo-European root aleg meaning to suffer. Word "pain" is later and comes from the Latin word "poena" meaning punishment. Since ancient times there has been disagreement regarding the perception of pain and its evaluation.

Job Opening for Nucleosome Mechanic: Flexibility Required
Cells, 2020 The nucleus has been studied for well over 100 years, and chromatin has been the intense focus of experiments for decades. In this review, we focus on an understudied aspect of chromatin biology, namely the chromatin fiber polymer’s mechanical ...

Mechanisms of Mechanotransduction [PDF]
Developmental Cell, 2006 Essentially all organisms from bacteria to humans are mechanosensitive. Physical forces regulate a large array of physiological processes, and dysregulation of mechanical responses contributes to major human diseases. A survey of both specialized and widely expressed mechanosensitive systems suggests that physical forces provide a general means of ...

Putting Mechanics into Quantum Mechanics [PDF]
Physics Today, 2005 Nanoelectromechanical structures are starting to approach the ultimate quantum mechanical limits for detecting and exciting motion at the nanoscale. Nonclassical states of a mechanical resonator are also on the horizon.

Modal Analysis of a Discrete System in the Form of a Rocket Launcher Installed on a Motor Vehicle [PDF]
Problemy Mechatroniki, 2016 A discrete model of an unguided rocket missile launcher installed on a motor vehicle was developed on the basis of a real assembly. The model is simplified to a vertical plane; it has four degrees of freedom and is adapted for a modal analysis.
