Towards a more comprehensive assessment of the intensity of historical European heat waves (1979–2019)

open access: yesAtmospheric Science Letters, 2022
Europe has been affected by record‐breaking heat waves in recent decades. Using station data and a gridded reanalysis as input, four commonly used heat wave indices, the heat wave magnitude index daily (HWMId), excess heat factor (EHF), wet‐bulb globe ...

Enhancement of heat transfer using ultrasonic waves: Experimental investigation and empirical correlations

open access: yesCase Studies in Thermal Engineering, 2023
This work aimed to investigate the effect of ultrasonic waves on heat transfer enhancement under a subcooled pool condition. For this purpose, a cylindrical rod is submerged in distilled water and a 1.7 MHz ultrasonic transducer was utilized to generate ...

Intense heat waves: dynamical-physical factors and characteristics of these heat waves

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2017
Dynamical and physical factors that trigger and maintain heat waves (HW) were examined. Since high pressure systems play a role in HW processes, an atmospheric blocking method was introduced.

Parental exposure to heat waves improves offspring reproductive investment in Tetranychus urticae (Acari: Tetranychidae), but not in its predator, Phytoseiulus persimilis (Acari: Phytoseiidae)

open access: yesEcology and Evolution, 2023
The more frequent and intense occurrence of heat waves is a challenge for arthropods because their unpredictable incidence requires fast adaptations by the exposed individuals.

On the atmospheric background for the occurrence of three heat wave types in East China

open access: yesWeather and Climate Extremes, 2023
Compared with daytime (occurring only in daytime) and nighttime (occurring only in nighttime) heat waves (HWs), daytime-nighttime compound HWs (occurring simultaneously in daytime and nighttime) are highlighted to exert much severer impacts especially on

Gravitational wave heating

open access: yesPhysical Review D
It was shown in previous work that when a gravitational wave (GW) passes through a viscous shell of matter the magnitude of the GW will be damped and there are astrohysical circumstances in which the damping is almost complete. The energy transfer from the GWs to the fluid will increase its temperature.

Characterization and Spatial Coverage of Heat Waves in Subtropical Brazil

open access: yesAtmosphere, 2019
Given the increase in the frequency, intensity, and persistence of heat waves since the 1970s, and in view of the impacts that extreme temperatures may cause for society and the economy, this study aims to characterize heat waves in the subtropical ...

Effects of Autumn and Spring Heat Waves on Seed Germination of High Mountain Plants. [PDF]

open access: yesPLoS ONE, 2015
Alpine plants are considered to be particularly vulnerable to climate change and related extreme episodes, such as heat waves. Despite growing interest in the impact of heat waves on alpine plants, knowledge about their effects on regeneration is still ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
