EFFECT OF TWO YEARS NATURAL AGING ON BURST PRESSURE OF OVER-PRESSURE COPPER TUBE (MT)

open access: yesJixie qiangdu, 2023
To study the stability of the over-pressure reinforcement effect of the copper tube at room temperature, the burst tests for the small diameter soft TP2 copper tube at room temperature during the natural aging time of 0, 6, 12 and 24 months were carried ...

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Experimental investigation on frictional multiplier of steam-water two-phase flow in internally ribbed enhanced tubes

open access: yesAdvances in Mechanical Engineering, 2017
The frictional multiplier of steam-water two-phase flow in four-head internally ribbed tubes was experimentally investigated under two test conditions—adiabatic and heated. The internally ribbed tube has the following dimensions: outside diameter 28.6 mm,

Light-Pressure Tube [PDF]

open access: yesAmerican Journal of Physics, 1961
A device for demonstrating the pressure of light is here described. With present-day techniques it is not only possible to produce a gas pressure sufficiently low to reduce the radiometer effects to a negligible value compared with the light pressure effect, but it is also possible to maintain such a vacuum in a sealed-off tube for long periods of time.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Analysis of Flow and Pressure Pulsation in Draft Tube of Francis Turbine under Different Guide Vane Opening

open access: yesRenmin Zhujiang, 2023
In order to explore the influence of the opening of the movable guide vane on the flow and pressure pulsation in the draft tube of the Francis turbine,the steady and unsteady numerical simulations were carried out by establishing a three-dimensional full-
