Precisely management of water quality in urban rivers is of significant and water environmental capacity provide a useful tool. This study presented a water quality analysis simulation program model-based approach for dynamical load reduction in Ashi River, highly contaminated tributaries of Songhua River, China. The actual and surplus dynamic environmental capacity of CODCr and NH<s...

Intravascular ultrasound may be useful for studying the natural history of atherosclerotic lesions of different morphologies and for guiding interventional strategies. This study was designed to test the hypothesis that tissue appearance by intravascular ultrasound is related to the biomechanical properties of atheroma components. Forty-three atheroma caps were obtained from the abdominal aorta...

The objective of this article is to critically evaluate the methods that are used to assess outcomes of remineralization of dentin. Currently, the most used assessment methods fall either into quantitative analysis of the mineral content of the remineralized structures or dry measurements of their mechanical properties. Properties obtained from the dehydrated organic dentin matrix may not refle...

Sickle cell disease (SCD) is characterized by the abnormal deformation of red blood cells (RBCs) in the deoxygenated condition, as their elongated shape leads to compromised circulation. The pathophysiology of SCD is influenced by both the biomechanical properties of RBCs and their hemodynamic properties in the microvasculature. A major challenge in the study of SCD involves accurate characteri...

Recent evidence suggests that performance of complex locomotor tasks such as walking may be accomplished using a simple underlying organization of co-active muscles, or "modules", which have been assumed to be structured to perform task-specific biomechanical functions. However, no study has explicitly tested whether the modules would actually produce the biomechanical functions associated with...

The peak cap stress (PCS) amplitude is recognized as a biomechanical predictor of vulnerable plaque (VP) rupture. However, quantifying PCS in vivo remains a challenge since the stress depends on the plaque mechanical properties. In response, an iterative material finite element (FE) elasticity reconstruction method using strain measurements has been implemented for the solution of these inverse...

Distraction osteogenesis is a process that depends on biomechanics, where the application of progressive traction forces leads to bone lengthening by gradual new bone formation. (Illizarov, 1989a, 1989b) Consequently, stretching of surrounding soft tissues occurs at different tissue depths, allowing correction of severe skeletal dysplasias in short periods of time. However, biomechanical data f...
