Downstream processing is an essential part in the production of biomolecules and the optimization of these processes are of great value, since they can be both time consuming and expensive. One common type of enzyme used in different biotechnical approaches is proteases and in this study Protease X was investigated. In order to use the enzyme in a process, a purification procedure needs to be esta

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

It is Thursday morning and time for the miniature brains to have lunch. The temperature in the cell incubator is a comfortable 37 degrees, perfect for a tiny brain. Anna Falk prepares the nutrient solution that the cells need to grow. These are cells that have made the remarkable transformation from skin cells to stem cells and then to brain neurons. The small model of the brain is called an organ

The epidermal growth factor receptor (EGFR) is a receptor involved in cell proliferation. It is frequently overregulated in cancer cells, making it an attractive target for cancer therapeutics. One possible pharmaceutical is protease-X; a protein involved in the cleavage of the EGFR and thus, a way to regulate the receptor’s activity and lead the cancer cells to apoptosis. The aim of this thesis h

The purpose of this work is the development, identification and validation of a model for the simulation of a thermomechanical multistage production process chain for sheet steels. The process of interest consists of forming (in particular deep-drawing) followed by cutting and heat treatment. For the forming and cutting stages, the complete model is based in particular on a model for thermoelastic

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

In this work, an automated downstream process for the purification and formulation of a recombinant protein was integrated at lab scale in a single chromatography unit. The purification chain consists of three bind-and-elute chromatography columns, a flow-through membrane chromatography step, and a final ultrafiltration-diafiltration (UFDF) step to concentrate and formulate the sample. An integrat

Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. This report outlines the outcomes of an investigation into and the optimization of the solid-state fermentation proces

In this work, the interfacing of a poly(ethylene glycol) (PEG)-phosphate aqueous two-phase system with hydrophobic interaction chromatography (HIC) for primary recovery of an intracellular protein was evaluated. As a model protein, a recombinant cutinase furnished with a tryptophan-proline (WP) peptide tag was used and produced intracellularly in Escherichia coli (E. coli). E. coli cell homogenate

Are our cities prepared for the growing and rapid urbanization expected for the coming years? How do the new social, economic and environmental challenges affect the urban context, specifically informal settlements? How can we rethink sustainable urban design in vulnerable areas? To tackle these questions, this study will have a closer look at Port Elizabeth, a coastal city in South Africa, to und

In Sweden, municipalities organize a large share of public services but the conditions for providing these services differ considerably due to differences in size and wealth. In the wake of financial stress and New Public Management reforms the Swedish local governments seeks new ways to make both ends meet and still manage the services to be in line with the present (not the past) demands of the

The building sector is one that can be accounted for numerous impacts on the environment, both by extremely high consumption of resources, and by emitting green house gases to the atmosphere on a large scale. Retrofitting existing buildings tackles energetic and emission related issues and one way to go about such projects is through the process of high-performance building certification, within w

Ultrasonic Additive Manufacturing (UAM) is a hybrid manufacturing process that involves the layer-by-layer ultrasonic welding of metal foils in the solid state with periodic CNC machining to achieve the desired 3D shape. UAM enables the fabrication of metal smart structures, because it allows the embedding of various components into the metal matrix, due to the high degree of plastic metal flow an

Controlling the nucleation and crystal growth in solution-processed metal halide perovskite (MHP) thin films is the pivotal point in fabricating homogenous and pinhole-free films. Using scalable coating and printing techniques, vacuum and gas flow-assisted drying processes turn out to be the most promising methods to induce nucleation and crystallization. Yet, the exact interplay and nature of the

Structured reflective writing during clinical placement has been shown to be valuable for students’ learning and for their personal and professional development. The aim of this study was to examine clinical supervisors’ experiences of midwifery students’ daily written reflections on their practice at birthing units. A qualitative study was performed, and data were analysed using content analysis.
