The force-velocity (F-V) properties of isolated muscles or muscle fibers have been well studied in humans and other animals. However, determining properties of individual muscles in vivo remains a challenge because muscles usually function within a synergistic group. Modeling has been used to estimate the properties of an individual muscle from the...
Abstract Tendons must be able to withstand the forces generated by muscles and not fail. Accordingly, a previous comparative analysis across species has shown that tendon strength (i.e., failure stress) increases for larger species. In addition, the elastic modulus increases proportionally to the strength, demonstrating that the two properties co-v...
The combined force–length (F–L) properties of a muscle group acting synergistically at a joint are determined by several aspects of the F–L properties of the individual musculotendon units. Namely, misalignment of the optimal lengths of the individual muscles will affect the group F–L properties. This misalignment, which we named \(M_{\text{opt}}^{...
Background:
Conventional backpack straps are flexible. Due to this flexibility, backpacks freely move on the human back. In this study, a new design of backpacks with non-flexible straps is proposed.
Objective:
The aim of the present research is to demonstrate the possible differences between normal gait and steps while participants carry two di...
In magnetic fluid hyperthermia (MFH), nanoparticles are injected into a diseased tissue and then subjected to an alternating high frequency magnetic field. The produced heat may have a key asset to destroy the cancerous cells. The blood flow in a tissue is considered as the most complicated part of the MFH which should be taken into account in the...
Abstract Purpose: In magnetic fluid hyperthermia (MFH), nanoparticles are injected into diseased tissue and subjected to an alternating high frequency magnetic field. The process triggers sufficient heat to destroy the cancerous cells. One of the challenging problems during MFH is blood flow in tissue. In real conditions the heat which is transferr...
In magnetic fluid hyperthermia therapy, controlling temperature elevation and optimizing heat generation is an immense challenge in practice. The resultant heating configuration by magnetic fluid in the tumor is closely related to the dispersion of particles, frequency and intensity of magnetic field, and biological tissue properties.
In this study...
in this study the best position of a double-strap backpack which is popular among college students against spine in comparison with two other kinds of packs which can be used by college students are investigated during static standing and walking on force plate. The Amount of Changing in forward COM due to backpack carriage is the base reference of...
An abnormal narrowing of a blood vessel (stenosis) is investigated in this study. The present work provides a simulation of blood in a vessel with 50% stenosis. In addition, the effects of tissue surrounding the blood vessel on displacements and stresses in stenotic vessel wall are considered. The analysis consists of two distinct but coupled proce...
