Liposomes are closed spherical bilayered membrane structures in aqueous solutions, with an internal aqueous compartment entrapped by either a single or multiple concentric lipid bilayer(s). They can be used as a tool in research to mimic simple cell membranes, to study e.g. lipid-protein interactions, as well as they are extensively used as carriers of various molecules, especially for tumor targe
Background: The first six weeks following a delivery is a critical period for the mother and the newborn. Despite removing out-of-pocket fees at a postnatal care access point in some parts of Uganda, few mothers utilize pre-paid services. Data from a health facility providing pre-paid postnatal care services in rural Eastern Uganda, revealed that only 17.9% of the mothers came back for postnatal c
The purpose of this thesis is to examine how Aaker’s (1997) brand personality scale functions in a culture outside of its country of origin and develop a deeper understanding of how Swedish consumers ascribe commercial brands symbolic values in terms of human personality traits. The thesis applies a quantitative research approach where data aggregation and analysis is conducted in a total of thr
Julian the Apostate’s short rule has left in the historical records a clearly divisive picture. This thesis starts with that divisive nature of the reign of Rome’s last pagan emperor and aims to analyse some of the Apostate’s coinage iconography. Can the symbols used on the coins minted during his reign say something about his allegedly revolutionary rule? By choosing to focus on a set of ten symb
Automated information flow is an important way of optimizing the time used for analyzing processes. Other added benefits are that in a well-made automated system, the probability of human error diminishes because less liability is put on the person to manually transport and utilize the data. This notion of automation can be applied to the field of chromatography. This thesis investigates the poss
The area of Business and Human Rights, applies to all enterprises, including corporate law firms, which have not been examined yet, as thoroughly as others. On the other hand, the profession of law is regulated by codes of conduct that limit the actions of lawyers when they are preforming their mandate. Through a comparative legal methodology this research seeks to find out if the human rights res
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
The 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
Abstrakt Författare: Hanna Fagerberg & Erica Törnkvist Titel: Bilden av politisk höger- och vänster extremism – olika yrkeskategoriers syn på brottsligheten och könsrollerna i politiskt extrema miljöer Kandidatuppsats: SOCK04, 15 hp Handledare: Anna Rypi Sociologiska institutionen, höstterminen 2016 Politisk extremism förekommer i dagens samhälle men det finns en problematik kring begreppet
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
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 kontrollgruppen
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
This 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, w
