Partially premixed combustion using gasoline-like fuels on compression ignition engines shows great potentials to break the soot-nitrogen oxides trade off and reduce both emissions simultaneously. By simply adjusting the dilution strategies and injection events, the control of partially premixed combustion is relatively easier compared to other low-temperature combustion concepts. However despite

BACKGROUND: Preterm infants are susceptible to hyperglycemia and hypoglycemia, conditions which may lead to adverse neurodevelopment. The use of continuous glucose monitoring devices (CGM) might help keeping glucose levels in the normal range, and reduce the need for blood sampling. However, the use of CGM might be associated with harms in the preterm infant. OBJECTIVES: Objective one: to assess t

Background: Head computed tomography (CT) is a guideline recommended method to predict functional outcome after cardiac arrest (CA), but standardized criteria for evaluation are lacking. To date, no prospective trial has systematically validated methods for diagnosing hypoxic-ischaemic encephalopathy (HIE) on CT after CA. We present a protocol for validation of pre-specified radiological criteria

Bakgrund Med en snabbt växande äldre populationsgrupp kommer även andelen med kognitiva störningar, som demens, att växa. Det är således nödvändigt med forskning på kognition och åldrande. Denna avhandling, genom fyra delarbeten, redogör för testledareffekter vid kognitionsmätningar och hur yngre födelsekohorter (generationer) presterar bättre än äldre på kognitionstester. Den kommer även förklaraGiven a growing population of older adults and the common occurrence of natural as well as pathological cognitive decline, i.e. dementia, there is a need to better understand how to accurately measure and classify level of cognitive functioning. Both using multiple test administrators to collect cognitive data and what year the participant is born (birth cohort effects) can influence participants’

The murine embryonal stem (ES) cell virus (MESV) can express transgenes from the long terminal repeat (LTR) promoter/enhancer in undifferentiated ES cells, but expression is turned off upon differentiation to embryoid bodies (EBs) and hematopoietic cells in vitro. We examined whether a human immunodeficiency virus type 1-based lentivirus vector pseudotyped with the vesicular stomatitis virus G pro

In order to generate high voltage high pulsed power, klystron modulators necessarily contain at least one capacitor bank charging structure supplying the energy to be released during the pulse. Conventional charging structures are based on AC/DC front-end units typically based on diode rectifiers combined with on/off controlled power charging structures as a second stage, producing prohibitive lev

Cognitive Linguistics began as an apotheosis of lived experience, but has over the years diversified into many different stands, interpreting the notion of "experience" and along with it the notion of "cognition" in conflicting ways: individual or social, prelinguistic or linguistic, unconscious or conscious? These issues are not only philosophical as they hold crucial implications for methodology

In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. I first investigated the effect of an experimentally evolved female-limit

The modern human being is exposed to different kinds of light during a normal day, both natural light and adjusted lighting. The idea that light affects us is uncontested, and so affecting the light in turn becomes a question of well-being. It is often thought that abundant and strong lighting is good lighting, but this is far from always accurate. Moreover, the light from a regular lightbulb is i

How should we deal with city planning in a world that is rapidly turning urban, without destroying valuable nature assets along the way? The last decades are proof that the system we are using today is not up to the challenge. Therefore this thesis is showing a new approach to how comprehensive city planning can grow from nature based values and a deeper understanding of a city’s foundation. Toda

Purpose – Increasingly, last mile logistics is driven by customer-oriented strategies that requires better understanding of customers’ perceptions. This thesis views last-mile delivery as a service and aims to examine the relation of logistics service quality and other constructs used in service management literature to measure customers’ perception. Built on the operational definition of perceive

Safety is intertwined with learning, without learning safety would be a static construct. To advance, safety concepts and theories all rely on the art of processing knowledge and though learning attaining a contributing effect. In shipping, the abstract of a near-miss is promoted as ‘good business and economic sense because it can improve crew performance and reduce costs’. Studies have shown th

Forskningsfråga: Skiljer sig kapitalstrukturen mellan familjeföretag och icke-familjeföretag? Syfte: Studiens syfte är att undersöka om det finns en skillnad i kapitalstruktur mellan familjeföretag och icke-familjeföretag noterade på börsen i Sverige. Utöver det undersöks hur företagsspecifika variabler, som exempelvis storlek, bransch och lönsamhet, påverkar företagens skuldsättningsgrad. MetodResearch Question: Does the capital structure differ between family-owned and non-family-owned businesses? Purpose: The purpose of this study is to investigate whether there is a difference in capital structure between family-owned and non-family-owned companies listed on the Swedish stock market. Additionally, the study examines how firm-specific variables, such as size, industry, and profitabil

Designer fashion items hold a high status within the fashion industry. A designer brands’ culture, aesthetic, and exclusivity give their products a symbolic value that can be used by consumers to build identity or express qualities like success or wealth. Therefore it is natural that counterfeit fashion items emerge as an alternative for consumers who want to emulate these qualities, but for a che

Abstract The self-driving car (SDC) is about to exit fantasy and enter reality. SDCs are expected to be available for purchase in just a few years, and the new technologies that enable autonomous driving hold much promise, regarding safety, environmental impact, increased mobility and higher comfortability. However, there are worrying prospects, too. Some experts worry that the autonomous car

This project focuses on how a household in Malmö can manage a crisis situation with no electricity, water, heat and communication for 72 hours. This is due to the recommendation that we can take care of ourselves for 3 days in case of a crisis. This spring residents of Cape Town have been living with water restrictions of 50 litres per person per day. This can be compared to the 160 litres per per

Antalet rättsfall gällande oönskad publicering och spridning av andra människors privata material på Internet har ökat betydligt de senaste åren, med de s.k. Instagramupploppen 2012 som en sorts uppmärksamhetskulmen. Inget svenskt samlingsnamn som passar i alla dylika sammanhang har uppkommit och även om specifika detaljer skiljer sig åt från fall till fall, förefaller ärekränkningar förekomma somThe legal cases concerning unwanted online publishing of private material have experienced a significant rise in the last few years peaking around 2012 in Sweden, with initial assiduities around the issue being brought about by the “Instagram riots”. Up to this day, there is yet to be a collective term to entirely encompass these cases, and although the specific details differ between each case, t

User Experience is a concept that recently has gained a lot of interest in the high-tech consumer products industry. While technology development has converged and is starting to become a commodity and, as markets mature and loyal customers become more important, User Experience has emerged as a way to gain a competitive advantage. By studying literature, cases and articles, as well as interviewin

The topic of our thesis is Packaging Design as a Brand Building Tool and we are presenting the Scandinavian perspective. We found the topic interesting because, from a theoretical point of view, we identified a scarcity in research focusing on packaging design as a brand management tool, and from a practical point of view, we found out that businesses use packaging design at different levels in th
