Ecosystem responses to increased organic carbon concentration : comparing results based on long-term monitoring and whole-lake experimentation
(Taylor & Francis, 2019)
Recent increases in terrestrial dissolved organic carbon (DOC) concentrations in northern inland waters have many ecological consequences. We examined available data on carbon cycles and food webs of 2 boreal headwater ...
Ecosystem Services at the Archipelago Sea Biosphere Reserve in Finland: A Visitor Perspective
(MDPI, 2019)
The United Nations Educational, Scientific and Cultural Organization’s (UNESCO’s) Biosphere Reserves aim to be flagships of sustainable landscapes. Many of them are important locations for tourism and leisure activities. ...
Ecotoxicity assessment of boreal lake sediments affected by metal mining: Sediment quality triad approach complemented with metal bioavailability and body residue studies
(Elsevier BV, 2019)
There are several methods for studying metal-contaminated freshwater sediments, but more information is needed on which methods to include in ecological risk assessment. In this study, we compliment the traditional Sediment ...
Eco‐evolutionary dynamics driven by fishing : from single species models to dynamic evolution within complex food webs
(Wiley-Blackwell, 2020)
Evidence of contemporary evolution across ecological time scales stimulated research on the eco‐evolutionary dynamics of natural populations. Aquatic systems provide a good setting to study eco‐evolutionary dynamics owing ...
ECRIS plasma spectroscopy with a high resolution spectrometer
(American Institute of Physics, 2020)
Electron Cyclotron Resonance Ion Source (ECRIS) plasmas contain high-energy electrons and highly charged ions implying that only noninvasive methods such as optical emission spectroscopy are reliable in their characterization. ...
Ectomycorrhizal fungi in wood-pastures : Communities are determined by trees and soil properties, not by grazing
(Elsevier BV, 2019)
Traditional rural biotopes such as wood-pastures are species-rich environments that have been created by low-intensity agriculture. Their amount has decreased dramatically during the 20th century in whole Europe due to the ...
Edge-stress -induced spontaneous twisting of graphene nanoribbons
(American Institute of Physics, 2012)
We present a continuum model for spontaneous twisting of graphene nanoribbons driven by
compressive edge stresses. Based on a geometrically nonlinear theory of plates, we identify scaling
laws for the dependence of twist ...
Effect of 20 MeV Electron Radiation on Long Term Reliability of SiC Power MOSFETs
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
The effect of 20 MeV electron radiation on the lifetime of the silicon carbide power MOSFETs was investigated. Accelerated constant voltage stress (CVS) was applied on the pristine and irradiated devices and time-to-breakdown ...
Effect of a Rigid Sulfonamide Bond on Molecular Folding: A Case Study
(American Chemical Society, 2015)
A disulfonamide compound with bulky aromatic side chains was prepared, and its properties as a potential building block for foldamers were evaluated. Two different solvate crystal forms of the compound were identified and ...
Effect of atomic layer deposited zinc promoter on the activity of copper-on-zirconia catalysts in the hydrogenation of carbon dioxide to methanol
(Elsevier, 2023)
The development of active catalysts for carbon dioxide (CO2) hydrogenation to methanol is intimately related to the creation of effective metal-oxide interfaces. In this work, we investigated how the order of addition of ...
