Initiation and stagnation of room temperature grain coarsening in cyclically strained gold films [PDF]
Acta Materialia 169 (2019) 99-108, 2019 Despite the large number of experiments demonstrating that grains in a metallic material can grow at room temperature due to applied mechanical load, the mechanisms and the driving forces responsible for mechanically induced grain coarsening are still not understood.

Effect of the Stagnation Temperature on the Normal Shock Wave [PDF]
Journal of Computational Methods in Sciences and Engineering, 2009 When the stagnation temperature increases, the specific heat does not remain constant and start to vary with this temperature. The gas is perfect; its state equation remains always valid, except, it was called by calorically imperfect gas or gas at high temperature.

Assessment of the Impact of Stagnation Temperatures in Receiver Prototypes of C-PVT Collectors [PDF]
Energies, 2019 Concentrating Photovoltaic Thermal (C-PVT) solar collectors produce both thermal and electric power from the same area while concentrating sunlight. This paper studies a C-PVT design where strings of series-connected solar cells are encapsulated with ...

Effect of the stagnation temperature on supersonic flow parameters: Application for air in nozzles [PDF]
The Aeronautical Journal, 2007 AbstractWhen the stagnation temperature of a perfect gas increases, the specific heats and their ratio do not remain constant and start to vary with the temperature. The gas remains perfect; its state

Flat Plate Aluminum Heat Pipe Collector with Inherently Limited Stagnation Temperature
Energy Procedia, 2014 This paper presents a new flat plate collector technology based on heat pipes. The use of heat pipes can lead to several advantages over direct flow collectors: A simple hydraulic interconnection, an inherently limited stagnation temperature and substitution of copper.

Poincaré index formula and analogy with the Kosterlitz-Thouless transition in a non-rotated cold atom Bose-Einstein condensate [PDF]
Journal of High Energy Physics, 2022 A dilute gas of Bose-Einstein condensed atoms in a non-rotated and axially symmetric harmonic trap is modelled by the time dependent Gross-Pitaevskii equation.

Rotation induced grain growth and stagnation in phase field crystal models [PDF]
Phys. Rev. E 88, 020401(R) (2013), 2013 We consider the grain growth and stagnation in polycrystalline microstructures. From the phase field crystal modelling of the coarsening dynamics, we identify a transition from a grain-growth stagnation upon deep quenching below the melting temperature $T_m$ to a continuous coarsening at shallower quenching near $T_m$.

Shotgun Metagenomics Reveals Taxonomic and Functional Shifts in Hot Water Microbiome Due to Temperature Setting and Stagnation [PDF]
Frontiers in Microbiology, 2018 Hot water premise plumbing has emerged as a critical nexus of energy, water, and public health. The composition of hot water microbiomes is of special interest given daily human exposure to resident flora, especially opportunistic pathogens (OPs), which ...
