We study liquid-liquid dispersions in a turbulent Taylor–Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 1.4× 10 are reached. The liquids we use are a low-viscous Oil and pure Water or a Sodium Iodide solution with a refractive index matched to that of Oil, in order to get transparent dispersions. We first charac...

background anthracyclines are important components of many chemotherapeutic protocols. the present study aimed to evaluate the repolarization changes in electrocardiography (ecg) which may predict drug induced arrhythmia. materials and methods in this cross-sectional study, the recorded ecgs were assessed for qt dispersion (qtd), qt corrected dispersion (qtcd), t peak to tend dispersion (tped),...

This work studies the kinetics of crystallization charged microgels suspensions Poly-N-Isopropylacrylamide (PNIPAM) at low ionic strength. The liquid-crystal transition is induced by suddenly decreasing temperature microgel dispersion, and process monitored measuring temporal evolution static structure factor dispersion using light scattering. We find that crystal growth rate, indicated crystal...

Mesogenic ligands have the potential to provide control over the dispersion and stabilization of nanoparticles in liquid crystal (LC) phases. The creation of such hybrid materials is an important goal for the creation of soft tunable photonic devices, such as the LC laser. Herein, we present a comparison of isotropic and mesogenic ligands attached to the surface of CdSe (core-only) and CdSe/ZnS...

We carry out an analysis of the stability of a liquid jet into a gas or another liquid using viscous potential flow. The instability may be driven by Kelvin–Helmholtz KH instability due to a velocity difference and a neckdown due to capillary instability. Viscous potential flow is the potential flow solution of Navier–Stokes equations; the viscosity enters at the interface. KH instability is in...

OBJECTIVE This study aimed to improve knowledge about drug administration through enteral feeding tubes (EFTs) in order to minimize efficacy and safety problems. MATERIAL AND METHODS The study was performed in a public secondary care hospital with level II accreditation by the National Accreditation Organization (Organização Nacional de Acreditação ONA), in Fortaleza, Ceará, north-eastern Bra...

Over the past several decades, Luttinger-liquid theory has provided a framework for interacting electrons in one dimension. However, the validity of the theory is strictly limited to low-energy excitations where the electron dispersion is linear. Interacting electrons in one-dimension beyond the Luttingerliquid limit, where the underlying dispersion of electrons is no longer linear, exhibit int...
