Denna uppsats handlar i huvudsak om fenomenet celldisruption, att genomföra detta på industriell skala och analysera resultaten. Celldisruption är en process som används mycket brett inom bioteknik då själva processen går ut på att utvinna de intressanta ämnen som producerats i en cell. Idag produceras en stor mängd läkemedel cellulärt men även inom bland annat produktion av tvättmedel, ost och fä

The use of antenna arrays allows for direction-of-arrival (DoA) estimation in a radar system. The antenna elements in an array are conventionally positioned equidistantly on a grid, but they can also be placed relatively freely to form sparse antenna arrays. These non-conventional layouts could potentially offer improved DoA capabilities. In this work, a particle swarm optimization algorithm has b

This study attempts to unravel the stock market participation puzzle. It approaches the puzzle with the idea that access to information reduces entry costs and, hence, encourages stock market participation. The literature suggests that information dissemination occurs through social interaction. Therefore, higher social engagement increases the odds of stock market participation. This study questi

Following the Russian invasion of Ukraine, millions of displaced Ukrainians fled to EU Member States. The activation of the TPD allowed Ukrainians to enter the labor market immediately. This thesis addresses the barriers to labor integration faced by Ukrainian refugees with temporary protection in Malmö. Based on previous literature, Ukrainian refugees were expected to face labor integration barri

Examensarbetets syfte är att undersöka användandet av didaktiska metoder för att påverka gruppdynamik i undervisning i högstadiet inom matematik respektive musik. Frågeställningarna handlar om vilka sådana metoder som används och hur erfarenheten skiljer sig mellan lärare inom de två olika skolämnena. Två matematiklärare och två musiklärare har intervjuats – individuellt. Datan har bearbetats enliThe aim of this student paper to examine the uses of didactical methods to affect group dynamics in upper compulsory school in Sweden in education within mathematics and music respectively. The questions concern which such methods are used and how the experience varies between teachers in the two different subjects. Two mathematics teachers and two music teachers have been interviewed – individual

In modern information technology there is an increase in demand for high-speed communication. Looking at the popular applications of AI and machine learning, a trend is to implement dedicated hardware accelerators for faster and more efficient computing. However this puts more of a demand on the ability to transfer the large amounts of data in the form of weights, input data and results to and fro

Hybrid perovskites are interesting optoelectronic materials. The perovskite ABX3 structure offers a vast compositional space, and we have identified over 300 perovskite ions. This flexibility enables tuneable properties and has significantly contributed to the success of perovskite optoelectronics. However, this diversity also leads to confusion, ambiguity, and inconsistencies causing challenges f

(Formula presented) boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of (Formula presented) boson production chara

A combination of searches for the single production of vectorlike top quarks ((Formula presented)) is presented. These analyses are based on proton-proton collisions at (Formula presented) recorded in 2015-2018 with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of (Formula presented). The (Formula presented) decay modes considered in this combination ar

The short-lived apex of journalistic freedom that took place after Perestroika in the late 1980s and early 1990s has been followed by setbacks and stagnation of press freedom, in particular since Putin’s accession to power in 2000. Despite this, qualitative text analysis of commentary articles in some of the most important current Russian news sites strongly indicates that during 2008–2018, reader

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by anti-aquaporin 4 (AQP4) antibody-mediated astrocyte damage and subsequent demyelination. Prior attempts to treat NMOSD with interferon-beta (IFN-β), a disease-modifying therapy for multiple sclerosis, resulted in worsening of disease activity, with an unknown mechanism. Here, robust activation of the cGAS-STIN

The purpose of this study is to investigate whether there is a relationship between health and economic growth. Specifically, the study examines whether economic growth affects three selected health variables in a positive or negative way. Data from 38 OECD nations between 2000 to 2020 are used in a panel data regression with fixed effects to evaluate this. Three equations are formulated to analyz

Efforts were first made in the 1950s to regulate fire growth through the building codes. These efforts were limited to controlling the flame spread and smoke developed from the burning of the interior finish (walls and ceiling) of structures. They also included provisions for the fire resistance of walls and floors (and roofs) in some of these same structures. In the United States, the regulations

The magnesium, calcium, strontium and barium ions bind six, eight, eight and nine water molecules in the first hydration shell, and ca. 12, 16, 16 and 18 water molecules in the second one, in dilute aqueous solution, respectively. With increasing concentration of alkaline earth metal halides, water molecules in the second hydration shell are exchanged for hydrated chloride and bromide ions forming

A soft magnetic core loss tester originally designed for sinusoidal flux excitation has been modified to enable multi-level PWM excitation. The setup is used to characterize an automotive-grade stator core under magnetic flux densities and excitation frequencies up to 1.4 T and 400 Hz respectively, as well as, switching frequencies between 4 and 16 kHz, with PWM voltage levels reaching up to seven
