Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022 Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.

Coherence and flow-maximization of a one-way valve [PDF]
arXiv, 2021 We consider a mathematical model for the gas flow through a one-way valve and focus on two issues. First, we propose a way to eliminate the chattering (the fast switch on and off of the valve) by slightly modifying the design of the valve. This mathematically amounts to the construction of a coupling Riemann solver with a suitable stability property ...

Mechanical Valve Replacement Versus Bioprosthetic Valve Replacement in the Tricuspid Valve Position [PDF]
Journal of Cardiac Surgery, 2013 The purpose of this study was to evaluate the clinical outcomes and risk of tricuspid valve replacements and to compare bioprosthetic versus mechanical valves.Between 1991 and 2009, 104 consecutive patients (71 women; mean age, 57 ± 10.8 years) with tricuspid valvular disease underwent mechanical TVR (mechanical group; n = 59) or bioprosthetic TVR ...

Non‐Surgical, In‐Stent Membrane Bioelectronics for Long‐Term Intracranial Pressure Monitoring
Advanced Healthcare Materials, EarlyView.This image shows a sequence of long‐term intracranial pressure monitoring using non‐surgical, in‐stent membrane bioelectronics. Abstract Traditional intracranial pressure (ICP) monitoring methods, using intraventricular catheters, face significant limitations, including high invasiveness, discrete data, calibration complexities, and drift issues, which

AGING MEDICINE, Volume 5, Issue 4, Page 257-263, December 2022., 2022 The main finding in our study is that Clinical Frailty Scale‐defined frailty status was predictive of 1‐year post‐interventional mortality after left ventricular assist device implantation. Abstract Objectives Heart failure impacts patients’ functional capabilities, ultimately leading to frailty.

The Influence of the Aortic Root Geometry on Flow Characteristics of a Bileaflet Mechanical Heart Valve [PDF]
arXiv, 2018 Bileaflet mechanical heart valves have one of the most successful valve designs for more than 30 years. These valves are often used for aortic valve replacement, where the geometry of the aortic root sinuses may vary due to valvular disease and affect valve performance. Common geometrical sinus changes may be due to valve stenosis and insufficiency. In

Comparison of the use of NiFe and CoFe as electrodes for metallic lateral spin-valves [PDF]
, 2015 Spin injection and detection in Co60Fe40-based all-metallic lateral spin-valves have been studied at both room and low temperatures. The obtained spin signals amplitudes have been compared to that of identical Ni80Fe20-based devices. The replacement of Ni80Fe20 by CoFe allows increasing the spin signal amplitude by up to one order of magnitude, thus ...

Aortic valve replacement in octogenarians [PDF]
Journal of Cardiothoracic Surgery, 2007 As our population ages and life expectancy increases the number of people aged over 80 and more referred for cardiac surgery is growing. This study sought to identify the outcome of aortic valve replacement (AVR) in octogenarians.68 patients aged 80 years or more underwent AVR at the Freeman Hospital, between April 2001 and April 2004.

AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract A possibility to carry out sorption‐enhanced gasification (SEG) is represented by its integration with the calcium looping concept in dual interconnected fluidized beds (DIFB). This article is focused on the sorbent CO2 uptake performance and attrition/fragmentation tendency when operating conditions simulating those of a DIFB‐SEG process are ...
