A method for three-dimensional particle sizing in two-phase flows [PDF]
, 2004 A method is devised for true three-dimensional (3D) particle sizing in two-phase systems. Based on a ray-optics approximation of the Mie scattering theory for spherical particles, and under given assumptions, the principle is applicable to intensity data

PLGA‐particle‐based vaccine induces SARS‐CoV‐2‐specific antibody and T‐cell responses
British Journal of Pharmacology, EarlyView.A novel coronavirus disease 2019 (COVID‐19) vaccine encapsulating recombinant severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike receptor binding domain (RBD) with the double stranded RNA (dsRNA) analogue Riboxxim induces robust systemic and respiratory T‐ and B‐cell responses in mice.

A Wind Study of Venus’s Cloud Top: New Doppler Velocimetry Observations
Atmosphere, 2020 At Venus’s cloud top, the circulation is dominated by the superroration, where zonal wind speed peaks at ∼100 ms−1, in the low-to-middle latitudes. The constraining of zonal and meridional circulations is essential to understanding the mechanisms driving

Reproductive, Female and Child Health, Volume 5, Issue 2, June 2026.ABSTRACT Objective To assess whether the hemoglobin–albumin–lymphocyte–platelet (HALP) score distinguishes fetal growth restriction (FGR) from small for gestational age (SGA) and its association with composite adverse perinatal outcome (CAPO). Method This retrospective study included 444 singleton pregnancies (214 FGR; 230 SGA) at a tertiary center ...

Ultrasonography with doppler assessment of the fetus with Intrauterine Growth Restriction (IUGR)
Indian Journal of Community and Family Medicine, 2016 There is a strong association between stillbirth and fetal growth restriction. Early detection and management of IUGR can lead to reduced related morbidity and mortality.

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]
, 2009 In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,
