Experimental study on the overall cooling effectiveness of nozzle guide vane under high temperature and high pressure

open access: yesCase Studies in Thermal Engineering, 2022
This study presents the overall cooling effectiveness of a nozzle guide vane with impingement-effusion in the conditions of the high temperature and high pressure at the mass flow ratios from KG = 0.09 to KG = 0.14. The temperature ratios change from KT =

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Singularities in mass-loaded MHD flow: The cometary bow shock [PDF]

open access: yes, 1991
We present a one-dimensional model of the mass-loading of the solar wind by cometary ions which predicts a singularity in the mass-loaded flow at M = 2. Further, a subshock occurs when the flow speed reaches M almost-equal-to 1.15.

Extended Mobile Bypass To Measure The Mass Flow Rate

open access: yes, 2015
The KONTAS-cp facility consists of a bypass with electric heating, temperature difference measurement and a Coriolis mass flow sensors to measure the specific thermal heat capacity (Cp) of heat transfer fluid (HTF). During the SFERA-II project, the measurement accuracy of the Cp-measurement is enhanced and an additional Coriolis mass flow sensor is ...

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Carbon Dioxide Absorption in Packed Column in Non-Newtonian Fluid

open access: yesTikrit Journal of Engineering Sciences, 2010
Absorption of carbon dioxide into carbonate solution (Na2CO3) with PAM (non-Newtonian fluid) has been performed in a countercurrent packed column (0.075m i.d. ×1.25 m height) packed with glass Raschig rings (1×1cm) to a depth of 1m.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
