    Abstract : Increasing atmospheric reactive nitrogen (Nr), as consequence of human activities, has generated accumulation of nitrate (NO3-) in Arctic regions. The Arctic has fragile nitrogen limited ecosystems that can be altered by increases of dry or wet deposition of Nr. READ MORE

  5. 3. Development of analytical methods for the determination of the small molecule component of complex biological systems

    Author : Kristian Pirttilä; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []

    Abstract : The research field of untargeted metabolomics aims to determine the relative abundance of all small metabolites in a biological system in order to find biomarkers or make biological inference with regards to the internal or external stimuli. This is no trivial aim, as the small metabolites are both vast in numbers and extremely diverse in their chemical properties. READ MORE

  6. 4. The economics of power generation and climate policy

    Author : Fredrik Pettersson; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This thesis consists of an introduction and six self-contained papers addressing the economics of electric power generation and climate policy. Paper I explores systematically the use of spatial econometric techniques in testing for convergence of CO2 emissions per capita across countries. READ MORE

  7. 5. Strong n-generators in some one-dimensional domains

    Author : Kerstin Pettersson; Daniel D Anderson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : Let R be a commutative Noetherian one-dimensional domain such that each ideal in R can be generated by n elements. A strong n-generator in R is an element r which can be chosen as one of n generators for each ideal in which it is contained. READ MORE
