Validation of human thermo-physiology models for personalized predictions of thermal responses

Dolaana Khovalyg, Mohamad Rida

Current thermal comfort models used in practice do not consider physiological and psychological differences of people. With this respect, human thermo-physiology models (HTPM) are useful tools to assess human thermal comfort at local and overall levels of ...

Modeling local thermal responses of individuals: Validation of advanced human thermo-physiology models

Dolaana Khovalyg, Mohamad Rida

Human thermo-physiology models (HTPM) are useful tools to assess dynamic and non-uniform human thermal states. However, they are developed based on the physiological data of an average person. In this paper, we present a detailed evaluation of two sophisti ...

Clinical detection of 'cold stress' is overlooked: an online survey of healthcare workers to explore the gap in neonatal thermal care in low-resource settings

Giorgia Brambilla Pisoni

Background Neonatal hypothermia has been widely regarded as a major contributory factor to neonatal mortality and morbidity in low-resource settings. The high prevalence of potentially preventable hypothermia today urges an investigation into why neonates ...

Interindividual variability of human thermoregulation: Toward personalized ergonomics of the indoor thermal environment

Dolaana Khovalyg

Objective The study was undertaken to show the magnitude of interindividual differences in energy expenditure (i.e., heat production) under normal living conditions with the aim of providing physiological evidence to support the advancement of a personaliz ...

Correction of Human Forehead Temperature Variations Measured by Non-Contact Infrared Thermometer

Adrian Shajkofci

Elevated body temperature (fever) can be a common symptom of a medical condition, such as a viral or bacterial infection, including SARS-CoV-2 or influenza. Non-contact infrared thermometers are able to measure forehead temperature in a timely manner and w ...

Operating Temperatures and Diurnal Temperature Variations of Modules Installed in Open-Rack and Typical BIPV Configurations

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Andrew Wayne Fairbrother

Because of building skin integration with restricted or reduced rear-side ventilation, elevated operating temperatures are expected in building-integrated photovoltaics (BIPV) modules and systems, which may impact their long performance and reliability. Th ...

New Insights Into the Pivotal Role of CREB-Regulated Transcription Coactivator 1 in Depression and Comorbid Obesity

Antoine Timothée Cherix

Depression and obesity are major public health concerns, and there is mounting evidence that they share etiopathophysiological mechanisms. The neurobiological pathways involved in both mood and energy balance regulation are complex, multifactorial and stil ...

Microfluidic and micromechanical in vivo studies of Caenorhabditis elegans

Roger Philippe Krenger

Caenorhabditis elegans is one of the most attractive model organisms in biomedical research for understanding human diseases and for drug testing at a whole-organism level, since many biological pathways and genes have been conserved between itself and hum ...

N-acetylaspartate availability is essential for juvenile survival on fat-free diet and determines metabolic health

Johan Auwerx, Dina Hofer

N-acetylaspartate (NAA) is synthesized by aspartate N-acetyltransferase (gene: Nat8l) from acetyl-coenzyme A and aspartate. In the brain, NAA is considered an important energy metabolite for lipid synthesis. However, the role of NAA in peripheral tissues r ...

Temperature regulates splicing efficiency of the cold-inducible RNA-binding protein gene Cirbp

Felix Naef

In mammals, body temperature fluctuates diurnally around a mean value of 36 degrees C-37 degrees C. Despite the small differences between minimal and maximal values, body temperature rhythms can drive robust cycles in gene expression in cultured cells and, ...

Thermal microsensors for in vitro and in vivo monitoring of chemical and biological processes

Rima Padovani

Metabolism is a highly coordinated biochemical cellular activity indispensable for sustaining life, and is often related to mitochondrial functioning. Innovative technological approaches allowing the study of the thermal signature of chemical and metabolic ...

Creep and stress relaxation of a FeMnSi-based shape memory alloy at low temperatures

Cyril Cayron, Christian Leinenbach

The creep and stress relaxation behavior of a Fe-17Mn-5Si-10Cr-4Ni-1(V,C) (wt%) shape memory alloy at low homologous temperatures (-45 degrees C < T < 50 degrees C) was systematically studied in stress and strain controlled tensile tests. At constant stres ...

Statistical analysis of the current-sharing temperature evolution in Nb3Sn cable-in-conduit-conductors for ITER

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov, Davide Uglietti

During the test of ITER conductors at nominal conditions, a degradation of the current sharing temperature has been observed after electromagnetic cyclic loading. Rather than focusing on the microscopic phenomena at the origin of the degradation, the degra ...

Evaporation from a small water reservoir: Direct measurements and estimates

Marc Parlange, Shirit Cohen

Summary Knowing the rate of evaporation from surface water resources such as chan¬nels and reservoirs is essential for precise management of the water balance. However, evaporation is difﬁcult to measure experimentally over water surfaces and several tech¬ ...

Glut2-dependent glucose-sensing controls thermoregulation by enhancing the leptin sensitivity of NPY and POMC neurons

David Genoux

The physiological contribution of glucose in thermoregulation is not completely established nor whether this control may involve a regulation of the melanocortin pathway. Here, we assessed thermoregulation and leptin sensitivity of hypothalamic arcuate neu ...
