Laser ablation is gaining acceptance as a cancer treatment technique because of its localized energy delivery to the tumorous tissue. The combination laser with nanoparticles allows for more precise targeting ablative area less damage adjacent healthy Nevertheless, heat tissue still potential concern. Therefore, mathematical modeling laser-tissue interactions necessary part clinical planning. I...

Abstract The current bioenergy uses and conversion technologies as well future trends for the production of heat, power, fuels chemicals from biomass are reviewed. focus is placed in Austria, which selected due to its high utilization, providing 18.4% gross energy final consumption 2017, strong industrial scientific position field. most common application Austria bioheat with 170 PJ 2017 mainly...

A three-dimensional computational model is presented for studying the efficacy of high-intensity focused ultrasound (HIFU) procedures targeted near large blood vessels. The analysis applies to procedures performed at intensities below the threshold for cavitation, boiling and highly nonlinear propagation, but high enough to increase tissue temperature a few degrees per second. The model is base...

Nanoparticles enhanced freezing, termed as nanocryosurgery, is a newly emerging cryosurgical technique which has potential advantage in targeted tumor treatment. However, there are currently no models available to predict the effects of nanoparticles on cell-level biophysical events during cryosurgery. Here, we present a theoretical model through modifying Mazur’s equation and ice nucleation th...

A general three-dimensional bioheat equation for local tissue heat transfer has been derived with less assumptions, exploiting a volume averaging theory commonly used in fluid-saturated porous media. The volume averaged energy equations obtained for the arterial blood, venous blood and tissue were combined together to form a single energy equation in terms of the tissue temperature alone. The r...

Acupuncture is one of the most extensively used complementary and alternative medicine therapies worldwide. In this study, we explore use near-infrared light-emitting diodes (LEDs) to provide acupuncture-like physical stimulus skin tissue, but in a completely non-invasive way. A computational modeling framework has been developed investigate light-tissue interaction within three-dimensional mul...
