Optimization of the thermal performance of a lobed triplex-tube solar thermal storage system equipped with a phase change material.

The thermal performance of a PCM-based triple-tube lobed heat exchanger storage system is here simulated and optimized, including performance improvements via lobed surfaces, Y-shaped fins, dispersed multi-walled carbon nanotubes, and metal foams, to be used in combination, or singly. Such computations are done with the finite volume method under different operating conditions. The reason behind this study is to look for solutions to improve the poor thermal performance of phase change materials (PCMs) as thermal energy storage materials, that limits their compactness and instantaneous heat stored/released.

Implementing a group-based online mental well-being program for women living with and beyond breast cancer - A mixed methods study.

Purpose: There is a gap in available mental well-being services in Australia for women diagnosed with breast cancer. This pilot mixed-methods uncontrolled study aimed to assess the feasibility of an online mental health and well-being intervention, the Be Well Plan (BWP), which enables participants to create a personalized, flexible well-being strategy.

Methods: Women diagnosed with stages I-IV breast cancer were recruited into 4 asynchronous groups to participate in the BWP, a 5-week facilitator-led group-based mental health and well-being program.

Microwave ablation modeling with AMICA antenna: Validation by means a numerical analysis.

Background And Objectives: Percutaneous microwave thermal ablation is based on electromagnetic waves that generate dielectric heating, and it is widely recognized as one of the mostly used techniques for tumor treatment. The aim of this work is to validate a predictive model capable of providing physicians with guidelines to be used during thermal ablation procedures avoiding collateral damage.

Methods: A finite element commercial software, COMSOL Multiphysics, is employed to implement a tuning-parameter approach.

Emprint Microwave Thermoablation System: Bridging Thermal Ablation Efficacy between Human Patients and Porcine Models through Mathematical Correlation.

To investigate the in vivo ablation characteristics of a microwave ablation antenna in the livers of humans with tumors, a retrospective analysis of the ablation zones was conducted after applying Emprint microwave ablation systems for treatment. Percutaneous microwave ablations performed between January 2022 and September 2022 were included in this study. Subsequently, immediate post-ablation echography images were subjected to retrospective evaluation to state the long ablated diameter, short ablated diameter, and volume.
