The Filament Extension Atomization Process for Powder Production of Elastic Fluids

Chemie Ingenieur Technik, EarlyView.
Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Central and Obstructive Apneas in Heart Failure With Reduced, Mid-Range and Preserved Ejection Fraction

Frontiers in Cardiovascular Medicine, 2019
Background: Although central apneas (CA) and obstructive apneas (OA) are highly prevalent in heart failure (HF), a comparison of apnea prevalence, predictors and clinical correlates in the whole HF spectrum, including HF with reduced ejection fraction ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Similar predictive value of six-minute walking distance and B-type natriuretic peptide in heart failure with reduced to mid-range ejection fraction

Monaldi Archives for Chest Disease, 2019
The prognostic insights of heart failure (HF) with mid-range (40-49%) ejection fraction (HFmrEF) are not fully elucidated. We investigated whether the six-minutes walking test (6MWT) and brain natriuretic peptide (BNP) are predictive of outcome across ...

Atrial Fibrillation in Heart Failure With Preserved, Mid-Range, and Reduced Ejection Fraction

, 2017
OBJECTIVES The study sought to assess the independent risk factors for, consequences of, and outcomes with atrial fibrillation (AF) compared with sinus rhythm (SR) in heart failure (HF) with preserved ejection fraction (HFpEF) versus HF with mid-range ...

Preventing wall deposition in duct flows: The role of particle number density and flow direction

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Outcomes in Patients With Atrial Fibrillation Stratified by Body Mass Index and Heart Failure Status

JACC: Advances
Background: An obesity-survival benefit, called the “obesity paradox,” has been variably reported in patients with heart failure (HF) and those with atrial fibrillation (AF), but inconsistencies have been observed.

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

ESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...

Potention of L-carnitine supplementation on changes in ejection fraction and left ventricular dimension in case of dilatative cardiomyopathy in children [PDF]

, 2020
Background: Cardiomyopathy is a rare cardiac muscle disease with poor prognosis and high mortality. The main goal of dilated cardiomyopathy therapy is to restore and maximize cardiac function, but to date no medication has met these criteria.
