Chemical weathering in a moraine at the ice sheet margin at Kangerlussuaq, western Greenland

open access: yesArctic, Antarctic, and Alpine Research, 2019
Weathering caused by interaction between glacial sediments and water in exposed moraines needs to be studied to evaluate their possible effects on the global carbon cycle.

Acidification of till in Northern Finland: experimental study [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The acid neutralizing capacity of till and some effects promoted by increasing acidity, were studied in a number of tills in northern Finland. pH profiles were measured in the field and acid neutralizing capacity (ANC mmol/100 g sample) in the laboratory

Glacial geology and till geochemistry in ore exploration in the Tervola area, southern Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1998
Glacial geology and till geochemistry were studied in an ore exploration project in the Palaeoproterozoic Peräpohja Schist Belt in the Tervola area of southern Finnish Lapland. The starting point for the exploration were numerous Au-Cu-rich erratics, the

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Similarity analysis using rank in till geochemistry [PDF]

open access: yesBulletin of the Geological Society of Finland, 1991
A similarity analysis method based on Spearman's rank correlation coefficient (p) was developed aiming to indirectly measure the similarity between the geochemistry of till and bedrock. The study area lies in Central Finland, comprising c.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Lithostratotypes for Weichselian and pre-Weichselian sediments in southern and western Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1990
In this paper we define stratotypes for glacial and associated sediments in southern and western Finland. The Kauhajoki Formation in southern Ostrobothnia (Pohjanmaa) and the Kela Formation in western Uusimaa, comprise a complex sequence of sediments ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Sedimentation and lithostratigraphy of the Vuosaari multiple till sequence in Helsinki, southern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1995
A multiple till sequence interbedded with sorted sediments has been investigated at Vuosaari, Helsinki, Finland. The investigation was carried out using standard sedimentological procedures combined with microfossil analysis in order to determine the ...
