The genetics of choosing your own path The soil bacteria streptomycetes play a vital role in our modern society as key producers of antibiotics used to treat infections all over the world (Slonczewski, J. et al., 2017). As over 50% of the antibiotics produced for medical use originate from streptomycetes (Slonczewski, J. et al., 2017), it is fair to say that these bacteria make up an essential co

Juice homogenization is mostly done to create smaller fiber particles, which reduces the sedimentation velocity to a lower level. So far, fruit juice concentrate is diluted to juice before it is homogenized. The first aim of this research paper is a feasibility study regarding the homogenization of fruit juice concentrate before it is diluted to juice. That would save capacity and energy. Secondl

Solen är bara en utav miljardtals stjärnor i Vintergatan - vår hemgalax. Likt en myrstack kan Vintergatan som helhet vid en första anblick verka simpel. Men när man tar en närmare titt upptäcker man att varje invånare har sitt eget liv, vilket bidrar till en komplex natur. Därför blir det svårt att få information om Vintergatans omfattande egenskaper genom att undersöka enskilda stjärnor. Men precThe use of reliable distance estimates is key to derive accurate three-dimensional velocities of celestial objects. Systematic overestimation and large uncertainties in the distances will thus provide misleading information of an object's kinematics. In turn, astronomers will get a flawed understanding of dynamical properties of substructures in the Milky Way. In this paper, we employ the imp

Today, technology is everywhere in our everyday lives whether it is wanted or not. The world has become digitalized and this development continues for each year that passes. The Swedish government has now (2018) updated the curricula for both kindergarten and elementary school to include more digital aspects in the teaching. With this background, this thesis (project) set out to design a digital a

Fretting is a complex set of mechanical and electrical mechanics that occurs at the contact surface between two vibrating objects. It is widely present in electrical connectors close to combustion engines due to the constant exposure to vibrations. Fretting is an extensive problem in the automotive industry but little research is done. In this thesis, a connector attached to a high pressure fuel p

I de centrala delarna av södra Sverige finns ett tektoniskt gränsområde som traditionellt sett har kallats Protoginzonen. Det har agerat som gränsen mellan bergarter vilka undkommit svekonorvegisk deformation och metamorfos i öster, och bergarter som upplevt den svekonorvegiska bergskedjebildningen till väster. Norr om Vänern kallas detta gränsområde numera Sveconorwegian Frontal Deformation Zone South-central Sweden hosts a tectonic boundary region which traditionally has been called the Protogine Zone. It acts as the boundary between rocks which have escaped Sveconorwegian deformation and metamorphism to the east, and rocks affected by the Sveconorwegian orogeny to the west. North of lake Vänern, the boundary zone is nowadays referred to as the Sveconorwegian Frontal Deformation Zone. Th

Data augmentation is a process to create new artificial data by altering the available data set. It has by many been considered a key factor for increasing robustness and performance of image classification tasks using deep learning methods, such as the convolutional neural network. This report aims to investigate the effect of data augmentation for the segmentation of magnetic resonance (MR) imag

Very little is known about the remarkable ability of humans to separate a single sound source from a dense mixture of sound sources in a crowded background, known as the cocktail-party scenario. Better understanding could lead to a breakthrough for the next-generation of hearing aids to have the ability to be cognitively controlled. A key finding in the field is that human cortical activity has be

Syfte: Syftet är att undersöka faktorer till varför företag i Sverige väljer att byta revisorer och även att bidra till tidigare forskning genom att bekräfta eller komplettera tidigare forskningsresultat. Metod: Studiens urval bestod av 94 börsnoterade svenska företag, från Stockholmsbörsens small-, mid- och large cap-listor där 47 hade bytt revisor mellan 2009–2015 och 47 utgjorde kontrollgruppenPurpose: The purpose of this study is to examine factors related to Swedish companies' choices to change auditors and also to contribute to prior research by confirming or adding to the results of prior research. Methodology: The study's sample consisted of 47 listed Swedish companies, from the Stockholm stock exchange's small-, mid- and large cap-lists, who've changed auditors bet

Background: Globalization is a phenomenon which has been around since the mid- 19th century, influencing companies to either expand existing markets or entering new markets, to seek new profits. For companies with a global supply chain, the total supply chain cost is a vital factor. It is of high importance to reduce the costs in the supply chain, as lower costs will increase the profit. The case

Utvecklingen går snabbt framåt och att vara ständigt uppkopplad har under många år varit vardag för människan. Men med ny teknik kommer nya möjligheter och det är nu även dags för industrin att koppla upp sig, vad som ofta benämns som den fjärde industriella revolutionen eller industri 4.0. På Assa Abloy vill man nu undersöka vilka möjligheter som finns med den nya tekniken och ett examensarbete mThis master thesis has been carried out to investigate the possibility to predict battery failure of Nickel-Metal Hydride (NiMH) batteries. Assa Abloy use these batteries as a back-up in their door solution systems in case there is a power loss. The main function is to be able to open doors that are part of an emergency exit route. Thus, approximately 200 battery packs were used to collect data re

High data rate is still the most crucial factor in cellular systems, and with 5g approaching new techniques are studied to achieve higher bit rates. Using MIMO technology, the spatial domain was exploited through beamforming and multiplexing multiple users’ data together assured more spectrum efficiency which resulted in higher bit rates. Reciprocity based beamforming is feasible in TDD systems du

Tauopathies belong to a group of neurodegenerative diseases that are characterized by the presence of neurofibrillary tangles in neurons and includes diseases such as Alzheimer´s disease and frontotemporal dementia. Neurofibrillary tangles are insoluble deposits that are composed mainly of tau, which normally acts to stabilize microtubules. In disease, tau forms fibrillar and oligomeric species, wHelpers of helpers – co-chaperone proteins and protein aggregation Proteins are one of the essential molecules that make up our bodies and the bodies of all living beings. Chaperone proteins exist as a protein ¨helper,¨ folding, maintaining, and regulating other proteins. To help these helpers, co-chaperone proteins, ¨helpers of helpers,¨ regulate chaperone proteins and help them by carrying out

The analytical method that has been used are a semiotic analysis and intermed

Background: Blockchain technology has during the last years become a hot topic for supply chain management. Solutions are being developed and sold, but exactly what blockchain technology can bring to the supply chain is unclear. The technology can be divided into two main varieties, public and private. The public version sparked the initial interest in the technology but has not been as heavily pr

This thesis is a qualitative study on how the current President of the European Commission, Jean-Claude Juncker, views the on-going project of European integration and how he constructs a ‘European identity’. The sample material consists of his three State of the Union speeches from 2015, 2016 and 2017, where Juncker reflects on events in the past year and presents the European Commission’s coming

In Sweden there are several political goals stating the importance of diminished quantities of waste from the food sector, yet several thousand tons of potentially edible food are being discarded of every year. This study has examined the hindrances and opportunities of six different organizations/initiatives working to lower the rates of food waste from retail stores. It has also looked into pote

Emphasis is being placed on how life narratives can be incorporated into caring for the elderly based on the assumption that aged health care should be grounded on narrative perspectives in order to reduce ageist behaviours. The success of this however depends on the willingness of the elderly to share their stories. The aim of this study was to explore the reasons why Swedish elders decline to sh
