An economically sustainable process was developed for propionic acid production by fermentation of glycerol using Propionibacterium acidipropionici and potato juice, a by-product of starch processing, as a nitrogen/vitamin source. The fermentation was done as high-cell-density sequential batches with cell recycle. Propionic acid production and glycerol consumption rates were dependent on initial b
Over the past decades there has been a shift in world politics, from a state-centric view of world order towards a new global world order. Non-Governmental Organizations (NGOs) play an important role in this era of globalisation. Through an analysis, based on Rosenau´s view of the new global world order, the purpose of this study is to explore and discuss the complexity with an increased role of

The thesis you’re about to read is based on the new possibilities of communication that social media can enable in the recruitment process. The aim of the study has been to explore the relatively unexplored area of social media connected to HR. Theories used conce
The industrialization of the Swedish construction industry has long stood in the shadow of the traditional construction methods. Problems such as high costs, long construction times and tough regulations have made the development stagnate. However, the industrial manufacturing industry has shown rapid growth within recent years. The culture within the industry has changed through innovative constr
In conventional design of pile foundations, all loads are taken by the piles, i.e. the contact pressure between the raft and the soil is neglected. In the last decades geotechnical engineers have started to take this pressure into account in design of pile foundation. Such a foundation, where the raft and the piles interact to transfer the loads to the ground, is in this dissertation called piled
Even though healthcare in Sweden is under pressure, assistant nurses are getting more tasks while still being asked to perform the current ones in a non-stressful manner. At the same time, the amount of people in need of assistance is increasing. A person asking for assistance with a basic task such as a shower is daunting. The purpose of this master thesis is to, through a design process, investi
This is a project in product development made for ASSA ABLOY Entrance Systems which is a manufacturer of sliding doors among other products. The objective of this project is to come up with a solution which offers an improved air sealing capability for a set of sliding doors all while the friction remains either the same or lower compared to before. The development process began with collecting in
Uppsatsen undersöker om Högsta domstolen (HD), genom att frångå lagstiftarens intentioner avseende vad som ska utgöra normalstraffet för mord, har överskridit sina befogenheter enligt regeringsformen (RF). Med normalstraff avses det straff domstolarna utgår ifrån när det bestämmer straffvärdet. I Sverige utgår all offentlig makt från folket, vilket betecknas som folksuveränitetsprincipen. Det voThe paper examines if the Supreme Court, by not following the legislator´s intentions regarding what the normal penalty for murder should be, has exceeded its powers under the Instrument of Government. Normal penalty refers to the penalty that the courts proceed from when deciding the penal value. The public power in Sweden proceeds from the people. It would be difficult to implement that the pe
In today's digital era, where personalized experiences have become crucial to consumer interactions with brands, the balance between personalization and privacy remains a complex and evolving challenge. Despite the recognized benefits of personalization in driving consumer spending, concerns about privacy and data security persist among individuals. This study addresses the "personalizati
Denna studie är en fallstudie av en byggnad belägen i Malmö, Sverige, som undersöker olika energieffektiva åtgärder och deras potentiella påverkan på byggnadens energikonsumtion. En förstudie genomfördes för att inhämta kunskap om tillämpliga energieffektiva åtgärder från befintlig forskning. Därefter genomfördes fallstudien i tre huvudsakliga faser. I den första fasen samlades byggnadsinformationThis study is a single case study of a building situated in Malmö, Sweden, examining various retrofit measures and their potential impact on the building’s energy performance. A pre-study was carried out to gain knowledge on applicable retrofitting measures from existing literature. Subsequently, the case study consisted of three major phases. In the first phase, building information was collected
En föränderlig omvärld ställer ständigt nya krav på organisationer; utveckling och anpassning är ständigt pågående processer. Framgångsrika idéer har blivit en handelsvara som recept på framgång. I dag har dessutom ett större antal av dagens medarbetare kapacitet att ta till sig de idéer som florerar och kommunikationsforskningen har inte riktigt hunnit med i denna aspekt. Denna uppsats är en kvalAn ever changing world is constantly putting new demands on organizations; development and adjustment are ongoing processes. Successful ideas have become merchandises as recipes for success. Additionally, a larger amount of co-workers has the capability to embrace the flourishing ideas and the communicational research has not been up-todate in this matter. This thesis is a qualitative case study o
Den här texten behandlar auktorisationsregler, med ett särskilt fokus på lärarlegitimationer. Det huvudsakliga syftet är att avgöra om utformandet av lärarlegitimationsreformen var det riktiga för att uppnå syftet med reformen, men texten fungerar även som en sammanställning av gällande rätt. Det är särskilt viktigt för lärarlegitimationer, där reglerna aldrig satts i något sammanhang. De auktorisThis text is a treatment on occupational licensing, with a focus on certification for teachers. The main purpose is to determine if the format used when the certification was implemented in 2011 was the right way to accomplish the purpose of the reform. The text also works as a summary of applicable law, which is important regarding teachers, since it has never been done before. The examined occup
In urban areas, the battle of space is more important than ever. The spaces and environments we grow up in are shown to be crucial for the identity we develop throughout our childhood. Therefore, the way our cities are designed and developed can largely impact who we become. The whole perception of society starts with children’s play, yet we tend to deprioritize their playing environments. For dec
Wireless communication has seamlessly integrated itself into our daily lives, with Ericsson pioneering the development of comprehensive mobile ecosystems. As the demand for data traffic continues to surge, the enhancement of both cellular radio systems and backhaul infrastructure remains paramount. Within this context, Ericsson leverages microwave transport network solutions to address backhaul ne
The key success factor for companies is to develop and deliver services and products that satisfy customer needs and create customer value. When introducing e-businesses as a new channel, it is becoming increasingly important to consider customers, since they will have a higher level of influence on the company through the interactive channel. This paper sets out to describe the process of conside
In the present thesis the development and application of a novel laser diagnostic system for high speed spectroscopic imaging of turbulent combustion phenomena is presented. The system is capable of recording sequences of up to 8 images with a separation between consecutive images as short as microseconds. The system allows a number of established laser diagnostic techniques to be used, extending
