Electro-Thermal Modeling and Design of High-Current Pulse Power Supply for Electrically Assisted Manufacturing

open access: yesIEEE Access, 2019
Electrically assisted manufacturing (EAM) is a promising and rapidly developing metal processing method. The power supply is a key sub-system for EAM, which needs to be designed properly.

A further discussion on the effective thermal conductivity of metal foam: An improved model [PDF]

open access: yes, 2015
In this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Thermal transfer simulation regarding the rotational moulding of polyamide 11 [PDF]

open access: yes, 2013
Simulation of thermal phenomena in rotational moulding is very important to follow the evolution of the temperature in various zones of this process. It was a question of modelling heat gradients developing in rota-tional moulding part.
