Heave motion suppression of a Spar with a heave plate [PDF]

open access: yesOcean Engineering, 2004
Abstract Vortex shedding flow of an oscillating vertical cylinder with a disk attached at its keel is considered. This configuration is of interest for the offshore oil and gas industry. A finite difference method is employed to solve the incompressible Navier–Stokes equations in the primitive-variables formulation.

Exercise‐induced airflow changes in horses with asthma measured by electrical impedance tomography

open access: yesJournal of Veterinary Internal Medicine, 2021
Background Equine asthma (EA) causes airflow impairment, which increases in severity with exercise. Electrical impedance tomography (EIT) is an imaging technique that can detect airflow changes in standing healthy horses during a histamine provocation ...

Nicoletella semolina in the airways of healthy horses and horses with severe asthma

open access: yesJournal of Veterinary Internal Medicine, 2021
Background Nicoletella semolina was identified in the airways of horses and its low prevalence could be because of its difficult differentiation from other Pasteurellaceae. Objectives To develop a molecular method for the identification of N.

Bronchoconstrictive properties of inhaled 8-epi-Pgf2alpha in healthy and heaves-susceptible horses [PDF]

open access: yes, 2001
peer reviewedThe 8-epi-PGF2α is a marker of oxidative stress which is increased in lungs of asthmatic humans and heaves-susceptible horses. 8-Epi-PGF2α has also been demonstrated to be an in vitro and in vivo bronchoconstrictor in humans and rodents. We

Endobronchial Ultrasound Reliably Quantifies Airway Smooth Muscle Remodeling in an Equine Asthma Model. [PDF]

open access: yesPLoS ONE, 2015
Endobronchial ultrasonography (EBUS) revealed differences in the thickness of the layer representing subepithelial tissues (L2) between human asthmatics and controls, but whether this measurement correlates with airway smooth muscle (ASM) remodeling in ...
