This thesis examines two different impacts of sidestream treatment of digester supernatant via nitrification-denitrification in a sequenced batch reactor (SBR). One of the impacts is the detrimental formation of nitrous oxide, and the other is the positive boosting of nitrifiers to the mainstream process through bioaugmentation. The studies have been carried out in a full-scale wastewater treatmen

With the increasing focus on reducing emissions and making fuel efficient vehicles within the automotive industry over the past few years, new methods are constantly being investigated to improve the efficiency of the powertrain. One such method is recovering waste heat from the exhaust gases as well as the coolant using a thermodynamic cycle such as a Rankine cycle. However, most studies looking

An investigation of the autonomy of the process region at the tip of a crack is carried out. An elastic plastic linearly hardening material is assumed. A cohesive zone model with constant cohesive stress is chosen. The cohesive zone length is observed to decrease with decreasing hardening rates and increasing cohesive stresses. For a cohesive stress larger than about three times the yield stress t

The adsorption of proteins is a very common phenomenon, happening almost always when a protein solution comes into contact with a solid. However, it is far from always clear what the results of adsorption will be in terms of adsorbed amount, protein orientation, and protein conformation. In this work, the adsorption of two proteins – histatin 5 and fibrinogen – has been studied using coarse-graine

Age is a critical determinant of arterial disease, including aneurysm formation. Here, to understand the impact of aging on the arterial transcriptome, we leveraged RNA-sequencing data to define transcripts that change with advancing age in human arteries. Among the most repressed transcripts in aged individuals were those that are relevant for actomyosin structure and organization, including both

Background: Several studies have examined the role of physical activity as a predictor of heart failure (HF) mortality and morbidity. Here, we aimed to evaluate the role of self-reported physical activity as an independent risk factor of post-discharge mortality and re-hospitalization in patients hospitalized for HF, as well as study the association between physical activity and 92 plasma proteins

This paper looks at process control in the pulp and paper industry from the perspective of pioneering work carried out in the early 1960s. One of the aims of the Billerud-IBM Project was to explore the technical and economical advantages that could be obtained by using a digital computer for control and supervision of a paper machine. The study also explored the features of a digital computer that

Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. Poor rehydration can cause challenges on an industrial level as well as for the consumers. In this thesis, sever
