Catalyzing social change: Does concentration encourage action?

open access: yesPLoS ONE, 2022
Countless social problems demand solutions, from climate change and gun control to poverty and systemic racism. But while some of these problems inspire action (e.g., “Black Lives Matter” and “Me Too” movements), most fail to gain traction or inspire new

Change of inspired oxygen concentration in low flow anesthesia [PDF]

open access: yesAnesthesia and Pain Medicine, 2020
Background There are several advantages of low flow anesthesia including safety, economics, and eco-friendliness. However, oxygen concentration of fresh gas flow and inspired gas are large different in low flow anesthesia.

Comment on Qian et al. 2008: La Niña and El Niño composites of atmospheric CO2 change [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2014
It is well known that interannual extremes in the rate of change of atmospheric CO2 are strongly influenced by the occurrence of El Niño-Southern Oscillation (ENSO) events. Qian et al. presented ENSO composites of atmospheric CO2 changes.

Unexpected Change in Thyroglobulin Concentration [PDF]

open access: yesClinical Chemistry, 2017
A high thyroglobulin (Tg) result was questioned as a possible laboratory error (Table 1). The sample corresponded to a 66-year-old male with a history of recurrent stage IV papillary thyroid carcinoma status post-thyroidectomy, routinely monitored for recurrence using Tg results and imaging studies.

Analysis of change in toluene concentration during periods with different industrial load [PDF]

open access: yesE3S Web of Conferences, 2023
A study of the peculiarities of the change in the concentration of toluene in the atmospheric air of the city, where the sources of the substance are both vehicles and an industrial enterprise for the production of synthetic rubber, has been carried out.
