Local thermal discomfort in low temperature environments

Thermal Science, 2019
Human local parts have different thermal responses to low temperature environment. The objective of this paper is to find out the most sensitive parts which are extremely discomforting in low temperature environments. Based on previous experimental data, the relationship among skin temperature, air temperature, and clothing insulation was ...

Rhoifolin Alleviates Ulcerative Colitis by Targeting NMNAT1 and Activating SIRT1‐FOXO1 Signaling to Enhance ILC3s Effector Function

Advanced Science, EarlyView.
Rhoifolin directly targets NMNAT1, thereby activating nicotinamide salvage pathway and promoting intracellular NAD+ biosynthesis. Elevated NAD+ levels enhance SIRT1 activity, leading to FOXO1 deacetylation and nuclear translocation. Nuclear FOXO1 subsequently binds to the IL‐22 promoter, upregulating IL‐22 transcription and potentiating ILC3 effector ...

Evaluating the Urban Heat Island Effect in Montreal: Urban Density, Vegetation, Demographic, and Thermal Landscape Analysis

Buildings
Montreal experiences a significant urban heat island (UHI) effect, potentially intensified by its dense urban structure, varied vegetation, and demographic distribution, leading to substantial outdoor thermal discomfort, especially during heatwaves.

Dual‐Responsive Hydrogels Integrate Bioelectrical Stimulation and Piezo‐Photocatalysis for Regenerative Treatment of Infected Wounds

Advanced Science, EarlyView.
A wireless, dual‐responsive hydrogel (PVA/(PVDF‐TrFE)/BiOClBr@PDA) is developed to promote efficient regeneration of infected wounds by integrating piezoelectric stimulation with piezo‐photocatalytic pathways. Under simultaneous light and ultrasonic stimulation, the hydrogel generates therapeutic electrical cues and reactive oxygen species, disrupting ...

Experimental characterization of the thermal performance of a school building prototype before and after refurbishment [PDF]

MATEC Web of Conferences, 2019
Portuguese school buildings are generally characterized by an in service thermal discomfort. The refurbishments that the schools have recently undergone, have not fully considered the climatic diversity and the economic reality of the country and, for ...

Self‐Powered All‐in‐One Wearable Bioelectronics Driven by Pneumatic Energy Buffering of Daily Footsteps

Advanced Science, EarlyView.
A pneumatic energy‐buffering strategy transforms transient and intermittent footsteps into quasi‐continuous electrical energy for a self‐powered wearable biosensing platform. The footwear‐integrated air‐pumping harvester, combined with the rationally designed power‐management system, powers a wearable ankle PPG device with reduced motion artifacts ...

Early-Stage Thermal Risk Diagnosis in High-Altitude Andean Residential Buildings: An Exploratory Envelope-Based Alert Matrix and Post-Simulation Discomfort Ratio

Buildings
High-altitude Andean climates present dual thermal pressure: daytime overheating risk coexists with nighttime heat loss within the same annual cycle. Aggregate energy indicators do not reveal the direction of thermal discomfort, limiting their utility ...

Perceived Time Shapes Physical Fatigue Accumulation and Its Neural Oscillatory Correlates

Advanced Science, EarlyView.
Can a clock change the course of physical fatigue? By covertly manipulating the clock calibration during repeated isometric contractions, we showed that perceived time shapes fatigue accumulation and frontal oscillatory dynamics. While fatigue accumulation was only reduced when the clock was slowed down, frontal oscillatory dynamics followed perceived ...

Thom’s Discomfort Index Variation in the Eastern Mediterranean City of Athens, Greece: Future Trends

Atmosphere
This study examines the evolution of thermal discomfort in Athens, Greece, using Thom’s Discomfort Index (TDI). The research commences from a historical reference period (1976–2005) and examines two future periods (2031–2060 and 2071–2100).

Identificação de ilhas de calor na área urbana de Ilha Solteira - SP através da utilização de geotecnologias Identification of urban heat islands in Ilha Solteira - SP municipality using geotecnologies

Engenharia Agrícola, 2010
Com a mudança climática prevista para as próximas décadas, os cientistas indicam que uma das consequências será o aumento das temperaturas médias e também o número de dias quentes, o que intensificará o desconforto térmico na população.
