Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

In process industry many control loops are far from optimally tuned. In this master's thesis a tool for rapid process identification and control design has been developed. The tool, which is implemented in Matlab 5.3, identifies a process model out of the step response of the real process. A PI or PID controller can then be designed and evaluated. The tool contains three different automatic de
Biogas, a mixture of methane and carbon dioxide, is produced by microorganisms upon degradation of organic matter in an anaerobic environment. It has been realised that by utilising anaerobic processes the organic pollutants in wastewater and organic solid waste from anthropogenic sources can be converted into a renewable source of energy. However, to fulfil the potential of anaerobic digestion in
A novel isolation and purification method was developed for producing 1,3-propanediol with high purity and high yield from the mixture containing 1,3-propanediol, 1,2-propanediol, glycerol, and glucose. The developed method, which consisted of phase separation and chromatography, was found to be a simple and efficient procedure for the isolation and purification of 1,3-propanediol from the other c

The goal of this master thesis project was to investigate and develop a minced meat analogue through high moisture extrusion and shredding of soy protein and vegetable fat. Soy protein in the form of soy protein concentrate (SPC) and soy protein isolate (SPI), vegetable fat in the form of high oleic canola oil and a blend containing partially and fully hydrogenated canola oil was utilized in the s
The purpose of this dissertation is to explore the heritagisation of Swedish sports, which is examined through studies of five Swedish sports museums of today. Additionally, the disseration explores the heritagisation of Swedish sports in a wider historical perspective, mainly focusing on the years between 1900 and 2000.There are plenty of sports museums in Sweden today, most of them run by amateu
Kemira Kemia AB produces a water treatment chemical named ”PIX-Sulfate”, where “PI” stands for “poly iron x”, and the “x” represents a conjugate ion, such as chloride or sulfate, in this case, sulfate. The main process for producing PIX Sulfate at Kemira’s plants today is to dissolve magnetite in diluted sulfuric acid and to oxidize the resulting liquid using oxygen. Currently, this process is car
