En två-kolonn MCSGP process för upprening av Liraglutid genomfördes i laboratorieskala. Den här processen är inte en kommersiell uppreningsprocess, utan att den är ett modellsystem med en realistisk peptidblandning och med en icke-kommersiell harts. Först modellerades processen med en konvektiv dispersiv modell för att beskriva koncentrationen genom kolonnen och den steriska massaktionsmodellen föA twin-column MCSGP process for the purification of Liraglutide was implemented at lab scale. This process is not a commercial separation step, but it is a model system with a realistic peptide mixture and with a non-commercial resin. First, the process was modeled using a convective dispersive model to describe the concentration along the column and the steric mass action model to describe the ad

This master’s thesis report describes the development of a new system for control and monitoring of a helium liquefaction plant which has been carried out at Kryolab, Lund University. At the plant, helium gas is purified and then cooled in several steps until it condensates. The plant is very similar to the ones constructed today, but Kryolab wished to replace the outdated control system. The new

A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p

In order to transform the fossil fuel dependent transport sector the promotion of biofuels has been crucial in the European Union’s transition towards climate neutrality. To ensure the sustainability of biofuels the European Commission published a Delegated Act on March 13th 2019, proposing the gradual phase-out of high emitting biofuels that may cause indirect land use change (ILUC) – one of them

The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo

This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. The thesis focuses on pulse characterization, through use of frequency-resolved optical gating (FROG), of

Cerebral Palsy (CP) has an impact on muscles and movement. This happens due to brain damage before the age of two years. Either sometimes before birth, during childbirth or after birth. According to hjarnfonden.se, 200 children are added annually in Sweden with CP. People living with CP have these weaknesses for the rest of their lives. CP is not progressive disorder, that means brain damage can’

In a GIS system, the need to encode geospatial data without standardized cartographic representations, such as population data, weather information, etc., on top of a map is common. This can be done with a layer on top of a base map, with the effect that the base map is partially or fully hidden. Reducing the opacity (or its equivalent - increasing the transparency) of this overlay data layer is a

The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. However, with continued device scaling, the performance of Integrated Chips (ICs) starts to deteriorate, making it essentia

The combined global emergence of a sustainable development discourse and Swedish policies requiring municipalities to rapidly build new housing have led Lund to develop Brunnshög. This pioneering megaproject balances urban expansion with high sustainability ambitions. Through the lens of urban political ecology, this thesis aims at analysing Brunnshög’s dominant sustainability narrative as told by

In this thesis, I discuss the difficulties Ukrainian refugees face in accessing and integrating into the Swedish labor market, the role of civil society organizations (CSOs) in Sweden with regard to the labor market integration of Ukrainian refugees, and the policy hindrance and CSOs’ limitation in achieving their goal for Ukrainian refugees. This thesis gathers qualitative data using semi-structu

In Skåne, Southern region of Sweden, where the idea that no Sámis live in the area is largely spread across the Swedish population, the few Sámis living there find themselves navigating their ethnic identity, between performativity, agency, and making use of the policies implemented at a national level. In a context of ongoing decolonisation of the Sámis and their lands, official institutions such

Den här studiens primära syfte är att jämföra och utvärdera två medborgardialogs metoder. De två metoderna är samrådsmöten och Public participatiory GIS (PPGIS).

The thesis aims to test the hypothesis if PPGIS is more effective as a public participation method. The thesis first evaluated the two me

Sentinel-2 based data provides interesting opportunities for land monitoring and applications in agriculture. High-Resolution Vegetation Phenology and Productivity (HR-VPP) is derived from Sentinel-2 data and offers up to 13 metrics. These metrics have a high spatial resolution (10x10m) and enables the possibility for in-field agricultural monitoring. The aim of this study is to evaluate four of t

This thesis’ main goals were to provide accurate forecasts and informative physical parameter estimates for energy use of the district heating in the Tingbjerg neighborhood, Copenhagen. Our work is aimed as a contribution for future work towards efficient on-demand energy production. We applied Dynamic Double Machine Learning to estimate the causal effects of weather observations on energy use. Th

This thesis is inspired by the lack of academic discourse on human rights aspects of human space settlement. It builds on the ever-growing literature on colonizing Mars and the ongoing public debate on the benefits versus disadvantages thereof. Taking on a critical approach, this thesis opens up a conversation on power, universalism, and legitimacy within space exploration, questioning both the on

A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. The detector uses multiple layers of solid coating containing 10B4C on the edges of a vo

Acknowledging, the research gap within sustainability transitions in analysing the local scale of transition processes, this work primarily, seeks to contribute to sustainability transitions studies by identifying the main factors that are enabling and hindering the materialization of low carbon mobility in Cuenca, Ecuador. The use of a case study as a research strategy and the nature of the rese

The behaviour and fate of stem cells is governed by the material properties of their surrounding microenvironment. Hence emulating the extracellular matrix poses as an attractive target for tissue engineering endeavours to create a stem cell substrate. Currently, the knowledge of the material properties is mostly limited to the macroscopic level which considerably limits the understanding of tissu
