Environmental Modelling: Learning from Uncertainty

Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. One critical question has become: how focused should uncertainty intervals be with consideration of characteristics of uncertain input dat

Progressive, transgenerational changes in offspring phenotype and epigenotype following nutritional transition

Induction of altered phenotypes during development in response to environmental input involves epigenetic changes. Phenotypic traits can be passed between generations by a variety of mechanisms, including direct transmission of epigenetic states or by induction of epigenetic marks de novo in each generation. To distinguish between these possibilities we measured epigenetic marks over four generati

Polymorphisms, haplotypes and mutations in the protamine 1 and 2 genes.

Protamines are the most abundant nuclear proteins and alterations in their expression have been described in infertile patients. Also, protamine haplo-insufficient mice have been described as infertile. Therefore, the protamine 1 and 2 genes have been considered important candidates in different mutational studies. In this article, we review all published articles related to protamine gene mutatio

Radiative Properties of Rare Earth Elements - Free and Bound in Crystals

This thesis is devoted to fundamental aspects, and to spectroscopic applications of radiative properties in free atoms and ions, as well as in ions doped into crystals. Using the time-resolved laser-induced fluorescence technique, measurements of radiative lifetimes for rare earth elements have been performed in neutral Pr, Nd, Tm, and in singly ionized Sm, Er, Nd, Tm, Yb, as well as in doubly io

Doppler Audio Signal Analysis as an Additional Tool in Evaluation of Umbilical Artery Circulation

Purpose: To investigate the predictive capacity of a new method for sound spectrum analysis of Doppler signals recorded from the umbilical artery in high-risk pregnancies. Material and Methods: The retrospective study comprised 127 pregnant women with various pregnancy complications between 23 and 39 gestational weeks. Umbilical artery blood flow velocity waveforms were recorded with Doppler ultra

Ecosystem services - current challenges and opportunities for ecological research

e concept of ecosystem services was originally developed to illustrate the benefits that natural ecosystems generate for society and to raise awareness for biodiversity and ecosystem conservation. In this article we identify major challenges and opportunities for ecologists involved in empirical or modeling ecosystem service research. The first challenge arises from the fact that the ecosystem ser

Monetary Policy, Asset Price Inflation and Consumer Price Inflation

The overall price level contains prices of everything purchased or purchasable (Fischer, 1911). The consumer price index only covers a small subset of all prices in the economy and since these prices are among the stickiest in the economy, this index may not fully capture the true rate of monetary inflation in the short run. Merging all price indices into one overall index has been rejected, not l
