In this article a number of whole-field blood velocity measurement techniques are concisely reviewed. We primarily focus on optical for in vivo applications, such as laser Doppler velocimetry (including time varying speckle), speckle contrast imaging and particle image tracking). also briefly describe nuclear magnetic resonance ultrasound velocimetry, two that do not rely access, but importance to measurement. Typical applications methods perfusion monitoring, the investigation instantaneous...
The wall shear stress plays a key role in the interaction between blood flow and surrounding tissue. To obtain quantitative information about this parameter, velocity measurements are required with sufficient spatial (and temporal) resolution. We present methodology for determination of vivo vitelline network chick embryo. Velocity data is obtained by microscopic particle image velocimetry using correlation ensemble averaging; latter used to increase signal-to-noise ratio measurements....
Abstract Endothelial cells (EC) translate biomechanical forces into functional and phenotypic responses that play important roles in cardiac development. Specifically, EC areas of high shear stress, i.e., the outflow tract atrioventricular canal, are characterized by expression Krüppel‐like factor 2 ( Klf2 ) transforming growth factor‐beta (Tgfβ)‐driven endothelial‐to‐mesenchymal transition. Extraembryonic venous obstruction (venous clip model) results congenital heart malformations,...
Ligating the right lateral vitelline vein of chicken embryos (venous clip) results in cardiovascular malformations. These abnormalities are similar to malformations observed knockout mice studies components endothelin-1 (ET-1)/endothelin-converting enzyme-1/endothelin-A receptor pathway. In previous we demonstrated that cardiac ET-1 expression is decreased 3 h after clipping, and ventricular diastolic filling disturbed 2 days. Therefore, hypothesise ET-1-related processes involved...
Local and regional energy systems are becoming increasingly entangled. Therefore, models for optimizing these more complex the required computing resources (run-time random access memory usage) increasing rapidly. The computational requirements can basically be reduced solver-based (mathematical optimization of solving process) or model-based (simplification real-world problem in model). This paper deals with identifying how multi-energy high spatial resolution change model complexity which...
In Germany, the current sectoral urban planning often leads to inefficient use of resources, partly because municipalities lack integrated instruments and argumentation strength toward politics, investors, or citizens. The paper develops ResourcePlan as (i) legal (ii) a instrument support efficient resources in neighborhoods. integrative, multi-methodological approach addresses natural building infrastructural sectors water (storm- wastewater) management, construction maintenance buildings...

Heating networks are highly relevant for the achievement of climate protection goals urban energy systems. This is due to their high renewable potential combined with plant efficiency and utilization rates. For optimal integration sector coupling heating in holistic systems, open source system modeling tools recommended. In this contribution, two approaches (the “Spreadsheet Energy System Model Generator”-integrated DHNx-Python module (DHNx/SESMG) Thermos) theoretically compared, practically...
This study identifies supply options for sustainable urban energy systems, which are robust to external system changes. A multi-criteria optimization model is used minimize greenhouse gas (GHG) emissions and financial costs of a reference system. Sensitivity analyses examine the impact changing boundary conditions related GHG emissions, prices, demands, population density. Options that align with both emission reduction changes called "no-regret" options. sensitive labeled as...
(1) The use of renewable energy for power and heat supply is one the strategies to reduce greenhouse gas emissions. As only 14% German households are supplied with energy, a shift necessary. This should be realized lowest possible environmental impact. paper assesses impacts changes in generation distribution, by integrating life cycle assessment (LCA) method into system models (ESM). (2) integrated LCA applied case study neighborhood Herne, (i) optimize supply, considering different...

A novel approach for ventilation systems is a periodically varying supply air flow rate, the so-called unsteady mode of operation. So far, useful effects this operating have been observed, but effect mechanisms are still not well understood. In article, simulations using recently proposed k-ω-ζ - ƒ model implemented in sensitized RANS computational framework cuboid room with swirl diffusers compared and validated PIV measurements calculations widely used RNG k-ε turbulence model, whose...
