Perioperative fluid therapy in adults and children: a narrative review

Frontiers in Medicine
Intravenous fluid administration is an important part of the management of the surgical patient. Fluid can be used to compensate for the normal turnover of fluid and electrolytes (maintenance), to replace losses, to expand the extracellular fluid space ...

Optimization of the Changing Phase Fluid in a Carnot Type Engine for the Recovery of a Given Waste Heat Source

Entropy, 2015
A Carnot type engine with a changing phase during the heating and the cooling is modeled with its thermal contact with the heat source. In a first optimization, the optimal high temperature of the cycle is determined to maximize the power output.

Natural Working Fluids for Absorption Refrigeration

, 2022
European and global regulations on greenhouse gases are constantly evolving. Most of the fluorinated refrigerants currently used are close to be banned due to their high global warming potentials. Therefore new alternatives less harmful to the environment need to be developed.

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Experimental investigation of Minimum Quantity Lubrication (MQL) of coconut oil based Metal Working Fluid

, 2019
Minimum Quantity Lubrication (MQL) is a technique of applying fine mists of Metal Working Fluid (MWF), instead a flood of it. This paper describes performance evaluation of novel coconut oil based MWF, during turning of AISI 304 Austenitic Stainless ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic 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.
