PMID: 26844128
Prev Med Rep. 2015 Jul 22;2:628-34. doi: 10.1016/j.pmedr.2015.07.005. eCollection 2015.

UNLABELLED: The purpose of this study is to evaluate whether the use of an activity monitor providing feedback has an effect on physical activity (PA) in young men. A population-based sample of 276 conscription-aged (mean = 17.9, SD =...

Pietiläinen M, Korpelainen H.
PMID: 23700503
AoB Plants. 2013;5:plt024. doi: 10.1093/aobpla/plt024. Epub 2013 May 02.

We investigated patterns of genetic variability in Saxifraga oppositifolia in the isolated Arctic Svalbard archipelago. The genetic analysis included genotyping using nine polymorphic microsatellite markers and sequencing of the nuclear internal transcribed spacer region. Among populations, mean allele numbers...

Measurement of osteogenic exercise - how to interpret accelerometric data?.

Frontiers in physiology

Jämsä T, Ahola R, Korpelainen R.

Front Physiol. 2011 Oct 18;2:73. doi: 10.3389/fphys.2011.00073. eCollection 2011.

Bone tissue adapts to its mechanical loading environment. We review here the accelerometric measurements with special emphasis on osteogenic exercise. The accelerometric method offers a unique opportunity to assess the intensity of mechanical loadings. We present methods to interpret...

A density functional study on dielectric properties of acrylic acid grafted polypropylene.

The Journal of chemical physics

Ruuska H, Arola E, Kortelainen T, Rantala TT, Kannus K, Valkealahti S.
PMID: 21476771
J Chem Phys. 2011 Apr 07;134(13):134904. doi: 10.1063/1.3556704.

Influence of acrylic acid grafting of isotactic polypropylene on the dielectric properties of the polymer is investigated using density functional theory (DFT) calculations, both in the molecular modeling and three-dimensional (3D) bulk periodic system frameworks. In our molecular modeling...

A Robust Bimodal Index Reflecting Relative Dynamics of EEG and HRV With Application in Monitoring Depth of Anesthesia.

Patterns of resource allocation in male and female plants of Rumex acetosa and R. acetosella.

Oecologia

Korpelainen H.
PMID: 28313405
Oecologia. 1992 Jan;89(1):133-139. doi: 10.1007/BF00319025.

Patterns of resource allocation in the dioecious Rumex acetosa and R. acetosella were investigated. Males were found to allocate more to reproduction during flower production than females, whereas females invested considerably more in reproduction during seed production. Altogether, females...
