Simultaneous Monitoring of Particle-Bound PAHs Inside a Low-Energy School Building and Outdoors over Two Weeks in France

open access: yesAtmosphere, 2021
The emergence of new super-insulated buildings to reduce energy consumption can lead to a degradation of the indoor air quality. While some studies were carried out to assess the air quality in these super-insulated buildings, they were usually focused ...

Experimental study of shear rate dependence in perpetually sheared granular matter

open access: yesEPJ Web of Conferences, 2017
We study the shear behaviour of various granular materials by conducting novel perpetual simple shear experiments over four orders of magnitude of relatively low shear rates. The newly developed experimental apparatus employed is called “3D Stadium Shear

Calibration of PurpleAir PA-I and PA-II Monitors Using Daily Mean PM2.5 Concentrations Measured in California, Washington, and Oregon from 2017 to 2021

open access: yesSensors, 2022
Large quantities of real-time particle data are becoming available from low-cost particle monitors. However, it is crucial to determine the quality of these measurements. The largest network of monitors in the United States is maintained by the PurpleAir

How granular vortices can help understanding rheological and mixing properties of dense granular flows

open access: yesEPJ Web of Conferences, 2017
Dense granular flows exhibit fascinating kinematic patterns characterised by strong fluctuations in grain velocities. In this paper, we analyse these fluctuations and discuss their possible role on macroscopic properties such as effective viscosity, non ...

Quantification of Element Mass Concentrations in Ambient Aerosols by Combination of Cascade Impactor Sampling and Mobile Total Reflection X-ray Fluorescence Spectroscopy

open access: yesAtmosphere, 2021
Quantitative chemical analysis of airborne particulate matter (PM) is vital for the understanding of health effects in indoor and outdoor environments, as well as for enforcing EU air quality regulations.

In Situ TEM Crystallization of Amorphous Iron Particles

open access: yesCrystals, 2020
Even though sub-micron and nano-sized iron particles generally display single or polycrystalline structures, a growing interest has also been dedicated to the class of amorphous ones, whose absence of a crystal structure is capable of modifying their ...

Partiklar i sørsamisk

open access: yesNordlyd: Tromsø University Working Papers on Language & Linguistics, 2023
The article presents the most central particles in Southern Sami, and argues that they constitute a separate part of speech different from adverbs. Most particles usually occur in the second position of the sentence, but several particles may also occur

Theoretical description of nucleons paired correlations of even-even nuclei in the adiabatic three-particle model [PDF]

open access: yesЯдерна фізика та енергетика, 2007
A hyperspherical adiabatic approach (HAA) has been suggested to find the energy spectrum of even-even atomic nuclei modelled by a spherically symmetric even-even core plus two valence nucleons in the external shell.

ELEMENTARY PARTICLES [PDF]

open access: yesProceedings of the National Academy of Sciences, 1964
In this brief survey I am going to borrow some ideas from a lengthy review prepared in collaboration with Murray Gell-Mann and Arthur Rosenfeld for publication elsewhere.* In the title of our article we have used the term “particle” but have carefully avoided the adjective “elementary”. Had the title of my paper here today been of my choosing, I should

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).
