Effects of marine fuel sulfur restrictions on particle number concentrations and size distributions in ship plumes in the Baltic Sea [PDF]

Atmospheric Chemistry and Physics, 2021
Exhaust emissions from shipping are a major contributor to particle concentrations in coastal and marine areas. Previously, the marine fuel sulfur content (FSC) was restricted globally to 4.5 m/m%, but the limit was changed to 3.5 m/m% at the beginning ...

In-depth characterization of submicron particulate matter inter-annual variations at a street canyon site in northern Europe [PDF]

Atmospheric Chemistry and Physics, 2021
Atmospheric aerosols play an important role in air pollution. Aerosol particle chemical composition is highly variable depending on the season, hour of the day, day of the week, meteorology, and location of the measurement site.

Sesquiterpenes dominate monoterpenes in northern wetland emissions [PDF]

Atmospheric Chemistry and Physics, 2020
We have studied biogenic volatile organic compound (BVOC) emissions and their ambient concentrations at a sub-Arctic wetland (Lompolojänkkä, Finland), which is an open, nutrient-rich sedge fen and a part of the Pallas-Sodankylä Global Atmosphere Watch ...

Aerosol size distribution seasonal characteristics measured in Tiksi, Russian Arctic [PDF]

Atmospheric Chemistry and Physics, 2016
Four years of continuous aerosol number size distribution measurements from the Arctic Climate Observatory in Tiksi, Russia, are analyzed. Tiksi is located in a region where in situ information on aerosol particle properties has not been previously ...

Gut microbiota composition reflects disease severity and dysfunctional immune responses in patients with COVID-19

Gut, 2021
Objective Although COVID-19 is primarily a respiratory illness, there is mounting evidence suggesting that the GI tract is involved in this disease. We investigated whether the gut microbiome is linked to disease severity in patients with COVID-19, and ...

Effects of a ready-to-drink thermogenic beverage on resting energy expenditure, hemodynamic function, and subjective outcomes

Journal of the International Society of Sports Nutrition, 2023
Background Thermogenic supplements are often consumed by individuals seeking to improve energy levels and reduce body fat. These supplements are sold in powdered or ready-to-drink (RTD) forms and consist of a blend of ingredients such as caffeine, green ...

Poetics of hypertimbralism in music

Proceedings (European Academy of Sciences and Arts), 2022
My presentation is an attempt to introduce and clarify an original concept which I called Hypertimbralism, that refers to music based on Hypertimbre as the foundation for musical composition.

The chemical composition of the Sun [PDF]

, 2009
We present a redetermination of the solar abundances of all available elements. The new results have very recently been published by Asplund et al. (Annu. Rev. Astron. Astrophys. 47:481, 2009).
