2. 1. Soluble and Plant Available Phosphorus in Acid Soils

   Author : Ann-Mari Fransson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; solubilisation mechanisms; Phosphorus extractions; Oxalate extraction; P fertilisation; Plant ecology; Växtekologi;

   Abstract : The P availability and solubility differ between soils and plants seem to have different ways of utilising the P present. The many P fractions present in soil interact and are closely related to another and transformations may easily occur. Due to this more P than the soluble fraction is available to plants. READ MORE

4. 2. Chemical characterization in the biorefinery of lignocellulose : Formation and management of oxalic acid and analysis of feedstocks for bioethanol production

   Author : Anders Sjöde; Nils-Olof Nilvebrant; Leif J. Jönsson; Arthur J. Ragauskas; Karlstads universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biorefinery; enzymes; ethanol; lignocellulosic feedstocks; oxalic acid; scaling; Biochemistry; Biokemi; Kemi; Chemistry;

   Abstract : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. READ MORE

5. 3. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

   Author : Lea Rastas Amofah; Helen French; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.

6. 4. Radioanalytical chemistry in emergency preparedness

   Author : Ulrika Nygren; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Abstract : Radioactive nuclides present a potential health hazard due to the ionising radiation emitted during their decay. The release of large amounts of radioactive nuclides is of concern both for man and the environment. READ MORE
