CALCULATION OF NON-ISOTHERMAL MOTION OF A TWO-PHASE COMPRESSIBLE MEDIUM AT IMPLOUSION

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2018
Hydrodynamic processes in a vertical well casing during implosion are considered. Mathematical modeling of the motion of a two-phase medium with a free surface is based on the volume of fluid method. Unsteady Reynolds-Averaged Navier-Stokes equations are

Assessment of Numerical Methods for Plunging Breaking Wave Predictions

open access: yesJournal of Marine Science and Engineering, 2021
This study evaluates the capability of Navier–Stokes solvers in predicting forward and backward plunging breaking, including assessment of the effect of grid resolution, turbulence model, and VoF, CLSVoF interface models on predictions. For this purpose,

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

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 ...

Modeling of vertical microplastic transport by rising bubbles

open access: yesMicroplastics and Nanoplastics, 2023
Microplastic particle concentration at the sea surface is critical for quantifying microplastic transport across the water-air interface. Previous studies suggest that the concentration at the sea surface is enhanced compared to bulk concentration, yet ...

Waveform Design Method for Piezoelectric Print-Head Based on Iterative Learning and Equivalent Circuit Model

open access: yesMicromachines, 2023
Piezoelectric print-heads (PPHs) are used with a variety of fluid materials with specific functions. Thus, the volume flow rate of the fluid at the nozzle determines the formation process of droplets, which is used to design the drive waveform of the PPH,

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

RADIAL AMNIOTIC FLUID INDEX AS A NEW AND ACCURATE METHOD FOR MEASURMENT OF AMNIOTIC FLUID VOLUME [PDF]

open access: yesActa Medica Iranica, 2006
Amniotic fluid volume (AFV) is one of the important parameters in the assessment of fetal well-being. The ability of ultrasound measurements to represent the actual AFV is unproven.

Potential Impact of Computational Techniques to Express the Solid Dynamics in (Gas-Liquid-Solid) Multiphase Reactors

open access: yesNUST Journal of Engineering Sciences, 2018
The computational fluid dynamics codes play a paramount role by demonstrating the system dynamics. The solid dynamics in a multiphase reactor can be analysed from (Chaos, Fractures, Clustering Discrete Element and Eulerian-Langrangian) simulation methods.
