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.

Crushing of interstellar gas clouds in supernova remnants: The role of thermal conduction and radiative losses

, 2004
We model hydrodynamic interactions of an old supernova remnant shock wave with a small interstellar gas cloud, taking into account the effects of thermal conduction and radiative losses. In particular, we consider a representative case of a Mach 30 shock

Concept of Enabling Over-Current Capability of Silicon-Carbide-Based Power Converters with Gate Voltage Augmentation

Energies
Various methods have been discussed in the literature regarding enabling the over-current (OC) capability of silicon carbide (SiC) MOSFETs. SiC MOSFETs can operate at up to 250 °C without failure. One of their features is to permit transient operation at

An Analytical Model of Dynamic Power Losses in eGaN HEMT Power Devices

Micromachines, 2023
In this work, we present an analytical model of dynamic power losses for enhancement-mode AlGaN/GaN high-electron-mobility transistor power devices (eGaN HEMTs). To build this new model, the dynamic on-resistance (Rdson) is first accurately extracted via

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Effectiveness of a Novel Low‐Density Lipoprotein Apheresis Device Rheocarna in Patients Undergoing Hemodialysis With Chronic Limb‐Threatening Ischemia: A Single‐Center Retrospective Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic limb‐threatening ischemia (CLTI) is a severe form of lower‐extremity artery disease characterized by distal lesions and microcirculatory impairment, limiting revascularization efficacy. Rheocarna is a direct hemoperfusion low‐density lipoprotein (LDL) adsorption device with potential rheological and anti‐inflammatory ...

Bone Conduction Improvement After Surgery for Conductive Hearing Loss [PDF]

Indian Journal of Otolaryngology and Head & Neck Surgery, 2011
The objective is to evaluate change in post-operative bone conduction in patients who underwent surgery for conductive/mixed hearing loss due to various reasons. The study design is of retrospective case review and tertiary referral center setting. Five-hundred patients with unilateral conductive/mixed hearing loss were divided into five equal groups ...

A conduction losses optimization strategy for DAB converters in wide voltage range

, 2016
Conduction losses, which are proportional to the square of rms inductor current, account for an important part of total losses for a dual active bridge (DAB) converter. A minimum rms inductor current control strategy based on Dual Phase Shift (DPS)

A simple overlap angle control strategy for reducing commutation torque ripple in a brushless DC motor drive

Engineering Science and Technology, an International Journal, 2017
A commutation torque ripple is generated in a brushless DC motor due to a finite time taken for current transfer between outgoing phase and incoming phase due to the phase inductance.
