Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF
A system for detecting protein-protein interaction using a bacterial two-hybrid approach, a heterologous expression system in Escherichia coli strain based on adenylate cyclase enzyme reconstitution, was invented twenty years ago (Karimova, et al., 1998, PNAS, 95:5752). Before inventing this system, yeast two-hybrid technology was used for screening putative interaction between either two proteins
In this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. The theoretical calculations used in this project are based on the approach made by Gurevich et al.
I detta examensarbete undersöks databasen Plantfacts som innehåller data om stålverk från hela världen. Syftet med detta är att utvärdera om det finns en koppling mellan primärt och sekundärt producerat stål och olika typer av stålverk i downstream-processer. För att utföra detta har databasen formaterats om i Excel med hjälp av Visual Basic for Applications (VBA). Från början var Plantfacts databIn this thesis the Plantfacts database is investigated, which contains data about steel plants from all over the world. The purpose is to evaluate wheter there is a coupling between primary and secondary steel and different types of steel plants in downstream processes. To achieve this, the database has been reformatted using Visual Basic for Applications (VBA) in Excel. Initially, the Plantfacts
The old observatory in Lund is a building which is protected by Kulturmiljölagen. The building has been empty for nearly 20 years and is in desperate need of renovation because of its poor condition and doesn´t live up to modern requirement for fire safety and accessibility. The municipality of Lund request suggestions for a new function for the observatory with related changes which could be acce
Secondary organic aerosol (SOA) plays a significant role in climate change by altering the global atmospheric radiation budget. Biogenic volatile organic compounds (BVOCs) are major sources for the formation of SOA. Their relationship is critical to understand the continental biosphere-aerosol-cloud-climate (COBACC) feedback mechanism but receives less attention in previous studies. In this study,
Background Digitalisation has a big impact on the financial services industry in terms of new business and cost cutting opportunities, but also as threats from disruptive competitors. The financial sector is also pressured by increasingly strict regulations. New and extended regulations drive costs associated with risk management and compliance which makes it more difficult to uphold historical pr
Increased digitalization and increased use of digital technologies in a multitude of applications affect companies and their environments. Adapting to the change is important to keep competitive advantage. Generally, small and medium-sized enterprises (SMEs) as well as the manufacturing industry are lagging behind in digitalization and digital maturity in comparison to larger companies and other i
Car sharing as an idea challenges the prevailing mobility regime in the global north that has been built around private vehicle ownership. Well established regimes such as this, over time generate norms and collect actors that become dependent on the private car as the dominant form of mobility. These norms and actors, whose very existence is at times contingent on upholding the current socio-tech
The general aim of the research is to explore the formation, maintenance, and use of social networks or social capital, which young migrants of Serbian origin living in Malmö have at their disposal. The research is circumscribed to second-generation Serbian immigrants (i.e. ‘young migrants of Serbian origin’) in Malmö, who were born or have lived here since childhood, with both parents of Serbian
In scanning probe microscopy the properties of the tip is crucial in determining which information that can be obtained from the resulting images and spectroscopy. Ordinarily metal tips are used for scanning, however by using semiconducting nanowires as tips one would have very well defined probes with more advanced possibilities for spectroscopic measurements. However, currently creating such hig
Electric road systems (ERS) provide electric power to vehicles en route (dynamic charging) and can reduce the need for onboard battery capacity. This thesis sets out to examine the power demand of an ERS and the integration of energy storage in its power supply for grid load alleviation and backup power. Specifically, the analysis is based on the ongoing project to build a permanent ERS on a 21 km
The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th
This thesis investigates a possible influence of language on thought in the domain of motion event descriptions using a cognitive-semiotic framework. Previous studies (e.g., von Stutterheim et al., 2012) have claimed that speakers of languages who construe situations as temporally ongoing through morphological aspect tend to focus more on the action itself and less on other details such as possibl
This study examines the long-term abnormal returns of stocks following Initial Public Offerings (IPOs) and Seasoned Equity Offerings (SEOs) on the Swedish and American markets from January 2000 to March 2021. Additionally, it examines the differences between Swedish and American companies and investigates factors influencing these disparities, focusing on the importance of market capitalization at
Today we live in an interconnected world. Through globalization and the development of information technology one can say that, today everyone is our neighbour. The result of our actions can easily spread and affect people on the other side of the world within seconds. Meanwhile, Third World countries are developing into stable economies and Western European corporations are expanding like never
In every population there are groups of minorities. These minority groups are often underrepresented on the labour market. This led us to the question whether or not this under representation is connected to the absence of cultural appropriate pedagogy in the education. In this study the specific minority group in focus is Indigenous Australians. By looking at educational programs with the aim to
