1. Rättsligt skydd av biologisk mångfald : etiska perspektiv och normkonflikter
Sammanfattning : En förutsättning för att vi ska uppnå en hållbar utveckling är att vi bevarar den biologiska mångfalden, vilken bland annat hotas av införsel och spridning av invasiva främmande arter. Ett viktigt instrument för att skydda den biologiska mångfalden utgörs av de rättsliga ramar som satts upp på internationell, EU- och nationell nivå. LÄS MER
2. An Experimental Study of Liquid Steel Sampling
Sammanfattning : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. LÄS MER
3. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils
Sammanfattning : 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.

4. Experimental and modelling studies of the thermophysical and thermochemical properties of some slag systems
Sammanfattning : In order to optimize the metallurgical processes it is necessary to improve the understandings of the industrial slag properties, which include thermophysical and thermochemical properties. In the present study Mass Triangle Model was applied to predict these properties. LÄS MER
5. A small scale wastewater treatment system adapted to nutrient recovery in cold climate : performance and possible sorbents
Sammanfattning : Waterbodies are impaired by, among other things, discharge from onsite small- scale wastewater (WW) treatment systems. Hence, these systems need to be updated to improve the effluent quality and the reuse of nutrients within society. LÄS MER
