Experimental study on the radon exhalation characteristics of block walls currently used in China

open access: yesNuclear Engineering and Technology
In order to establish a predictive model for indoor radon concentration in Chinese buildings, walls were constructed using Chinese-style bricks to study the relationship between radon exhalation rates and indoor radon concentrations, as well as the ...

The Effect of Temperature Gradients on the Exhalation Rate of Radon Generated by Building Materials [PDF]

open access: yes, 2019
There is increasing interest in indoor air quality studies. The effect of exhaled radon from soil, walls and ceilings has well-known consequences on human health, so the importance of modelling has been established.

Synchronization of Inhalation/Exhalation Ratio and Heart Rate Variability During Spontaneous Breathing

open access: yes
In this study, we investigate the relationship between breathing patterns and cardiac autonomic nervous activity during spontaneous breathing. Electrocardiograms and respiratory signals were simultaneously monitored in six subjects for 5 min while in a ...

Radon exhalation rate in south-east Sicily building materials

open access: yes, 2015
One of the main contributions to indoor radon levels is given by the exhalation from building materials. For this reason we performed measurements of radon exhalation rate in materials commonly used in buildings of the eastern Sicily.

Direct cortical stimulation–evoked symptoms in the human temporal pole: A systematic review

open access: yesEpileptic Disorders, EarlyView.
Abstract The temporal pole represents a key node within temporolimbic networks and may contribute to seizure generation in temporal lobe epilepsy. Direct cortical stimulation (DCS), performed during intracranial presurgical evaluation, is a valuable method for delineating the seizure onset zone by reproducing electro‐clinical features of a patient's ...
