Introduction: Endovenous laser treatment (ELT) is a new treatment method for the reflux of the great saphenous vein. A successful ELT is dependent on the selection of optimum parameters required to achieve optimal vein damage while avoiding side effects including skin burns. The mathematical modeling of ELT can be used to understand the process of ELT. This study was conducted to examine the ef...

The model of bioheat transfer in tissues has attracted many researchers due to its application in thermotherapy and human thermoregulation system. Currently bioheat is considered as a heat transfer in human body. In view of this the influence of heat and mass transfer on peristaltic flow in a non-uniform rectangular duct is studied under the consideration of long wavelength ð0 k ! 1Þ and low Re...

In order to avoid dangerous climate change greenhouse gas accounting methods are needed to inform decisions on mitigation action. This paper explores the differences between ‘attributional’ and ‘consequential’ greenhouse gas accounting methods, focusing on attributional corporate greenhouse gas inventories, consequential life cycle assessment, and project/policy greenhouse gas accounting. The c...

A three-dimensional mathematical model was developed to examine the transient and steady-state temperature distribution in the human brain during selective brain cooling (SBC) by unilateral intracarotid freezing-cold saline infusion. To determine the combined effect of hemodilution and hypothermia from the cold saline infusion, data from studies investigating the effect of these two parameters ...

One factor which may be important for determining proper lesion creation during atrial ablation is catheter-endocardial contact. Little information is available that relates geometric contact, depth and angle, to ablation lesion formation. We present an electrothermal computer model of ablation that calculated lesion volume and temperature development over time. The Pennes bioheat equation was ...

Burn treatment is an area of major importance in medicine, however, there is not currently an analytic method to determine the depth and magnitude of burns. Complications, such as a relative lack of knowledge of the specific thermal properties of skin and the relation between heat transfer and biological processes, have prevented a comprehensive model to explain the field of bioheat transfer. R...

BACKGROUND The aim of this study is to research the lesion outline and temperature field in different ways in atrial radiofrequency ablation by using finite element method. METHODS This study used the method which considered the thermal dosage to determine the boundary between viable and dead tissue, and compared to the 50 °C isotherm results in analyzing lesion outline. Besides, we used Hype...

Abstract This study attempts to develop a modified Pennes bioheat conduction model for skin tissue, by using space-fractional derivative. The developed fractional is applied capture the thermal behaviour of tissue subjected heating and cooling procedures. It found that with increase order, predicted temperature at stage increases, while it decreases stage. Irrespective value simulated along bot...

Photothermal therapy is an effective means to induce tumor cell death, since tumor tissue is more sensitive to temperature increases than normal tissue. Biological responses depend on tissue temperature; target tissue temperature needs to be precisely measured and controlled to achieve desired thermal effects. In this work, a unique photoacoustic (PA) sensor is proposed for temperature measurem...
