This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. The solutions used were based on molasses, which is a liquid containing mainly low-molar mass components and konjac glucomannan (KGM) which is a substance with high molar mass. The change of the mass transport
The thesis reviews research about assimilation and education of Turkish immigrants in Germany. The thesis describes Human Capital theory, multiculture and cultural hegemony and segmented assimilation model. By using descriptive quantitative methods, it shows that Turkish-German community tends to be isolated and exclusive mainly due to their family and father centered social structure which was br
In this thesis, the relationship between venture capital (VC) investments and startup success in Sweden is analysed. The selected startups have operated between 2010 and 2015, and have been funded by VC investments between 2010-2022. As a subgroup of private equity firms (PE), VCs support startups financially and strategically to expand companies. Logistic and linear regression models have been
The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI contr
People who don’t eat meat can suffer from iron deficiency due to the lower efficiency of absorption of non-heme iron compared to heme iron. The aim of this master thesis was to explore the possibilities of producing a plant-based alternative of heme-iron by evaluating the efficiency of expression of sugar beet hemoglobin in the methylotrophic yeast Pichia pastoris. The gene from sugar beet hemog
Addressing electronic waste is crucial for meeting the environmental needs of the 21st Century, as WEEE is one of the fastest growing waste streams. Spain has emerged as one of the top countries globally for per capita mobile phone consumption. For this reason, this thesis focuses on European and Spanish initiatives that am to improve the circularity of mobile phones through repair. In recent year
Avian malaria parasites are prevalent all around the world and infect a wide diversity of bird species. In this report the prevalence of Plasmodium lineages in Spanish house sparrows was studied. According to previous research, higher variation of Plasmodium lineages could be expected in southern climates. This was tested by using samples collected from Spain and performing nested PCR with primers
I svenska domstolar använder sig domarna av fri bevisvärdering vilket innebär att domarna inte är bundna av regler eller metoder för hur de värderar bevisning. Vissa principer, som omedelbarhetsprincipen, sätter upp gränserna för bevisvärderingen men i övrigt är denna fri. Det är även tillåtet att använda sig av så kallade erfarenhetssatser. Med erfarenhetssats avses att domarna har kunskap om etIn Swedish courts, the court use free evaluation of evidence, which means that the judges are not bound by rules or methods for how they evaluate evidence. Certain principles, such as the principle of immediacy, set the limits for the evaluation of evidence, but otherwise this is free. It is also permitted to use so-called common knowledge theorems. A common knowledge theorem is the knowledge of a
Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. Due to its short excited state lifetime and its cyclable 4f-5d transition, cerium has been deemed suitable for just this purpose.
Syftet med denna studie är att undersöka hur temperaturen påverkar dags- och månadsavkastningen på Stockholmsbörsen. Denna studie genomförs med en kvantitativ metod och studien bygger på sekundär finansiell data. Studien görs på Stockholmsbörsen och på indexet OMX Stockholm 30 (OMXS30) samt olika sektorsindex. Tidsperiod som väljs är per dag, per månad samt per årstid. Historiska dagstemperaturer
In the previous decades, mm-Wave frequency bands have largely been ignored for cellular communication because of the high free space attenuation as well as the cost and complexity of mm-Wave RF circuits. However, with the improvement of RF and antenna technologies over the last decade, it has become feasible to con- sider mm-Wave bands for cellular communications. With the large bandwidths availab
Tetra Pak delivers food packing services world-wide and uses multilayer packaging materials to protect the food product from being affected by the environment. Loss of adhesion between the polymer and the aluminium layer in Tetra Paks packaging materials has proven to be a serious problem casing the package to lose its integrity and the food product to spoil. The problem is relatively unstudied bu
Stereotyping and stigma of overweight people generate ostracism and also leads to health issues such as mental and/or physical illness. Earlier research shows that stereotypes in children´s books have a negative impact on children. The following study intends to analyze how overweight characters are portrayed in children's picture books. With a quantitative and qualitative content analysis thi
Under the growing influence of dominant discourses such as ecological modernisation and neo- liberalisation, proposed alternative conservation approaches focus more and more on efficiency. In the realm of biodiversity conservation, synthetic biology - the application of engineering to facilitate and accelerate the design or modification of genetic materials in living organisms – has emerged as an
This paper analyzes the impact of receiving refugees on municipal income, income inequality, and public finances. The empirical analysis compares Swedish municipalities between 2000 and 2018, a period with large and fluctuating waves of refugees, both across years and municipalities. This paper uses the variance within municipalities, i.e., fixed effects. The results show that an increase of the r
Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. For instance, one could gain a bound orbit around the Sun if the right amount of nudge is acquired wh
