Low-frequency (LF) noise (1/f as well as random telegraph-signal (RTS) noise) measurements were performed on high-performance InGaAs nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs). 1/f noise measurements at room temperature (RT) show that the dominant noise mechanism is carrier number fluctuations. The minimum gate area normalized input gate voltage noise power spectral

Popular summary: In my work I have studied the manganese ores at Bölet in Västergötland, southern Sweden. The ores at Bölet are of hydrothermal origin, which means that a hot fluid flushed through the bedrock and precipitated different salts and minerals. The purpose of the study was to determine the temperature of the precipitating fluids and to estimate their composition. To do so I examined mic
Fat-filled milk powders are manufactured by blending skim milk powder with vegetable oil and these powders have gained a great economic importance. Sensible selection of vegetable oil can help in satisfying both nutritional features and functional characteristics of fat for dairy application. The stability of milk powders can be affected by its composition, mainly the composition of fats which can
An article written by the Swedish Government in 2018 outlines that they are working towards a more equal society and describes how they are conducting prevention work regarding men’s violence towards women. Although recently media has portrayed street harassment and catcalling as something that has become an increasing problem for young women in Sweden. Therefore, the purpose of this study was to
Skiljeförfarande har under de senaste decennierna växt fram till en mycket populär och uppskattad metod för tvistlösning, särskilt bland kommersiella parter. En större partsautonomi, effektivitet och slutlighet har betonats som fördelar jämfört med domstolsförfarande. Samtidigt finns frågor och svårigheter att reda ut. En av dessa aspekter lyftes i samband med att delar av lagen om skiljeförfarandArbitration has over the past few decades emerged as a very popular and appreciated method of dispute resolution, especially among commercial parties. Greater party autonomy, efficiency, and finality have been emphasized as advantages compared to court proceedings. At the same time, there are issues to address. One of these aspects was highlighted when parts of the Swedish Arbitration Act (SAA) we
Purpose: The purpose of this thesis has been to examine if and how Swedish SMEs use post audit reviews to learn from their capital investment decisions. Methodology: This explorative study applies a qualitative research approach, using both primary and secondary data. The primary data was collected through semi structured interviews with six managers across six different Swedish SMEs, while secon
This thesis has been made in collaboration with the company Orbital Systems. The aim has been to optimize their product the Orbital shower, which is a circulating shower system. The work evaluates different sensor techniques suitable for detection of contaminants in greywater. After a comprehensive literature study, three techniques; ultrasound, IR and impedance were further investigated and prac
Stroke is one of the leading causes of death and the most common cause for disability among the adult population in Sweden, due in part to the fact that many patients do not arrive at the hospital in time for treatment. A system that could detect unilateral arm weakness based on arm movement, a common symptom of stroke, is therefore desirable. In recent years there has been rapid development in th
The present study explored the nature of the auditory P300 in response to filtered words in ten normal hearing adults. P300 waveforms were elicited by a classic oddball paradigm, and recorded using a net of 128 electrodes (HydroCel Geodesic Sensor Net 128 1.0.). P300 waveforms from central, parietal, temporal right and temporal left regions were selected for data collection. P300 latencies and amp
Emelie Fridell Källsortering i historisk miljö För företag och organisationer kan lokalers utformning och platsbrist gör dem mindre lämpade att ställa källsorteringsmöbler i. Detta kan innebära att en del historiska byggnader på grund av sin utformning har svårare att installera källsorteringsmöbler. Vid undersökning av AF-borgen i Lund gjordes en volymbestämning av avfallsmängderna i två lokaThe resources of our earth are limited and need to be managed sustainably. Managing waste is thus a global issue which makes recycling of waste an important part of sustainable resource management. Sweden has come a long way in source separation of waste compared to many other European countries, with recycling techniques and equipment for source separation, in use. However, most studies look at h
Key words: Innovation, start-ups, exploration, exploitation, formal networks Purpose: The purpose of this thesis is to explore the effects of formal network participation on exploration and exploitation activities in start-ups. Methodology: Following a cross-sectional design, an explorative study was conducted using semi-structured interviews. 18 interviews were performed with representatives fr
To simulate district heating networks, in this project the simulation environment Dymola was used. The goal was to run simulation of district heating network and at the same time have good network representation to easily change between different models and also change between doing simulation and optimization. Different models had to be created in Dymola and tested to ensure they work accordingly
The aim of this study was to explain and understand how the child perspective is used in child welfare investigations. The study was based on five interviews with social workers in a municipality in the southern part of Sweden. The main outcome of this study was that the concept child perspective is a multifaceted and complex concept, all the social workers had a different view on the child perspe
Popular Abstract in Swedish Södra Regionvårdsnämnden har önskat att få belyst om vi har en rättvis och jämlik cancervård i Södra sjukvårdsregionen. Därför har en populationsbaserad registerstudie med många olika etapper genomförts. Basinformationen har hämtats från Tumörregistret i Södra sjukvårdsregionen. Första diagnosdatum noterades och hemort (kommun, distrikt, län) samt sjukhus definierades eThe overall aim was to study different aspect of health care use and health care costs on a population based level for persons with cancer and their partners, and from an individual level to explore the impact of comorbidities in incidence and survival.

We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Pres
Biocompatibility studies of the autoxidized and unoxidized unsaturated medium-long chain length (m-lcl) co-poly-3-hydroxyalkanoates (m-lclPHAs) derived from soya oily acids have been reported. Pseudomonas oleovorans was grown on a series of mixtures of octanoic acid (OA) and soya oily acids (Sy) with weight ratios of 20:80, 28:72 and 50:50 in order to obtain unsaturated m-lcl copolyesters coded PH
