1. Free-Vehicle Benthic Lander Technology for the Study of Biogeochemical Processes in Marine Sediments
Abstract : Various sediment sampling and incubation techniques were used to characterize benthic biogeochemical processes important for an improved understanding of the oceanic carbon cycle. Recent flux data from the Arctic Siberian shelf are revealing differences (often by a factor of ten) between areas affected by the big Russian river outlets (high fluxes) and areas with low influence from land (low fluxes).

2. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective
Abstract : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. READ MORE

3. An insight into the metabolism of New Psychoactive Substances : Structural elucidation of urinary metabolites of synthetic cannabinoids and fentanyl analogues using synthesized reference standards
Abstract : New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. READ MORE

4. Size and dynamics of active soil organic matter fraction as influenced by soil management
Abstract : The determination of what has been termed an "active fraction" of soil organic matter (SOM) and the effect of management on the size and turnover of this fraction are the leading themes in the present thesis. The techniques employed to study the amount and turnover of this fraction include: long-term mineralization-incubations for determination of potentially mineralizable carbon (Co) and nitrogen (No), fumigation-incubation for determination of microbial biomass-C and N, and istotope techniques using 13C and 15N for determination of the dynamics of soil C and N.

5. In vitro studies of cytostatic drugs and growth factors on leukemic and normal hematopoietic cells : based on in vivo intracellular pharmacokinetics
Abstract : The aims were to develop, evaluate and apply in vitro methods for cytostatic drug sensitivity, based on intracellular concentrations found after in vivo infusions. The intracellular pharmacokinetics of anthraquinones and ara-C were compared during and after infusion to leukemic patients. Drug concentrations were evaluated with HPLC. READ MORE
