Sommario/riassunto

Sarcopenia represents the decline in skeletal muscle mass and function with age, characterized by the muscle fiber's quality, strength, muscle endurance, and metabolic ability decreasing, as well as the fat and connective tissue growing.Reduction of muscle strength with aging leads to loss of functional capacity, causing disability, mortality, and other adverse health outcomes. Because of the increase of the proportion of elderly in the population, sarcopenia-related morbidity will become an increasing area of health care resource utilization.Diagnostic screening consists of individuation of body composition, assessed by DEXA, anthropometry, bioelectrical impedance, MRI, or CT scan. Management is possible with resistance training exercise and vibration therapy, nutritional supplements, and pharmacological treatment.The book includes articles from different nationalities, treating the experimental and medical applications of sarcopenia. The consequences of sarcopenia in frailty are treated in relation to other associated pathologies or lesions, as femoral neck fractures and hepatocellular carcinoma.

Sommario/riassunto

This book presents a comprehensive introduction to an advanced beam theory applicable to thin-walled beams of rectangular and arbitrarily-shaped cross-sections. Furthermore, it describes a unique beam-based approach to handling joint structures consisting of thin-walled beams, compiled here for the first time. This higher-order beam theory (HoBT),



developed by the authors over the past two decades, uses more than six degrees of freedom (DOFs) in contrast to the classical theories, which use only six DOFs. The additional degrees of freedom describe sectional deformations such as warping and distortion. This book presents a novel systematic procedure to derive the sectional deformations analytically for rectangular cross-sections and numerically for arbitrarily-shaped cross-sections. This book is a must for structural/mechanical engineers who wish to understand and design structures involving thin-walled beams.
