Relationships between sanukitoids and crust-derived melts and their implications for the diversity of Neoarchaean granitoids: A case study from Surmansuo and nearby areas, Eastern Finland [PDF]
We present new isotopic data (U-Pb and Sm-Nd) from the Neoarchean granitoids of the Lentua complex, which is a part of the Western Karelia subprovince of the Fennoscandian Shield.

Rb-Sr whole-rock isotopic study of late Archaean and early Proterozoic granitoid intrusions, Kainuu, Eastern Finland [PDF]
A tonalite-granodiorite-granite suite emplaced during the late Archaean D3 deformational phase yields a six point isochron age of 2,500 ± 270 Ma and an initial 87Sr/86Sr of 0.7044 ±0.0018.

Timing of Svecofennian crustal growth and collisional tectonics in Åland, SW Finland [PDF]
In an effort to quantify the time parameter in the tectonomagmatic evolution of what has been called the Southern Svecofennian Arc Complex (SSAC) of SW Finland, advanced radiometric dating techniques have here been applied to rock groups of key ...

Age-dependent immune response to the Biontech/Pfizer BNT162b2 COVID-19 vaccination
Background: The SARS-CoV-2 pandemic has led to the development of various vaccines. Real-life data on immune responses elicited in the most vulnerable group of vaccinees over 80 years old is still underrepresented despite the prioritization of the ...

Mid- and late-Holocene shoreline changes along the southern coast of the Gulf of Finland [PDF]
In response to glacio-isostatic rebound in Estonia, a relative sea level fall occurred during the mid- and late-Holocene, and as a result, lowland regions in northern Estonia have experienced an evolution from sea to land.

The influence of training status, age, and muscle fiber type on cycling efficiency and endurance performance. [PDF]
The purpose of this study was to assess the influence of age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one of four groups: young and old trained cyclists, and young and old untrained ...

Absolute dating methods, mean ages and age uncertainty.
We include the most common dating methods (n = 10,720) entered in ROAD, but exclude mixed methods and less common absolute dating methods (n = 1566) as well as relative ages. When the age uncertainty on the y-axis (i.e.
