Chemical composition of outdoor and indoor PM2.5 collected during haze events: Transformations and modified source contributions resulting from outdoor‐to‐indoor transport

open access: yesIndoor Air: International Journal of Indoor Environment and Health, 2018
Changes in the chemical constitution and sources of ambient PM2.5 following the infiltration of air into indoor environments were investigated. We collected PM2.5 samples from air inside and outside 31 rooms in Beijing residences during hazy episodes. We

Taking race out of neuroscience too.

open access: yesCortex; a journal devoted to the study of the nervous system and behavior, 2017
In 2013 the French Parliament barred the term “race” from legislation. President Hollande proposed to drop the term “race” also from the first article of the 1958 French Constitution: “France is an indivisible, secular, democratic and social republic. It

Pyrolytic graphite as a selective neutron filter [PDF]

open access: yesЯдерна фізика та енергетика, 2006
The transmission of neutrons through pyrolytic graphite (PG) crystals, set at different angles with respect to incident beam, were calculated using an additive formula. A computer program HOPG was developed to provide the required calculation.

Atom cavity encoding for NP-complete problems

open access: yesQuantum Frontiers
We consider an atom-cavity system having long-range atomic interactions mediated by cavity modes. It has been shown that quantum simulations of spin models with this system can naturally be used to solve number partition problems.

Configuration transitions of divacancies in silicon and germanium [PDF]

open access: yesЯдерна фізика та енергетика, 2013
High-resistance samples p-Si (p0 = (1.63 - 7.09)·1011 cm-3) and n-Si (n0 = 1.19·1014 cm-3), grown by the float-ing zone melting after irradiation with fast neutron reactor at 320 C after isothermal and isochronal annealing were studied.

Dose estimates of 137Cs in bank voles inhabiting research sites within the Chornobyl Exclusion Zone considering the age-related dynamics of change in physiological parameters [PDF]

open access: yesЯдерна фізика та енергетика
Methods for dose estimation of 137Cs in mouse-like rodents, specifically bank voles (Myodes glareolus), commonly found within the research sites in the Chornobyl Exclusion Zone, are being proposed.

The Evaluation for Alterations of DOM Components from Upstream to Downstream Flow of Rivers in Toyama (Japan) Using Three-Dimensional Excitation-Emission Matrix Fluorescence Spectroscopy

open access: yesInternational Journal of Environmental Research and Public Health, 2011
The dissolved organic matter (DOM) is one of the important factors for controlling water quality. The behavior and constitutions of DOM is related to the risk of human health because it is able to directly or indirectly affect the behavior, speciation ...
