The main goal of this thesis was the development and application of a method to construct reactor networks based on pre-calculated flow fields for combustion systems. Computational fluid dynamics (CFD) was used to calculate flow fields for the Sandia piloted jet flame D and a Siemens SGT-800 gas turbine burner rig. Two different combustion models were tested in the computational fluid dynamics cal
Two methods of computational analysis of DNA barcodes are presented. A DNA barcode is formed by making GC-rich regions of a DNA molecule fluoresce while AT-rich regions remain dark, thus when stretched using nano-channels and viewed in a microscope, the DNA molecule will resemble a barcode with black and white stripes. Because of point-spread functions and pixellation the resolution will be roughl
During the last few years, crowding effects on the physics of proteins has become an increasingly popular topic of research. This is is because most biological processes involving proteins naturally take place in a crowded environment, e.g. in the cellular environment where macromolecules may occupy 30% of the volume. One such biological process would be the formation of amyloid aggregates, which
Forest fires can act as an ecosystem service by providing habitat renewal, controlling pests, and reducing the risk of extreme fires, but can at the same time disturb an ecosystem negatively. Furthermore, forest fires release carbon dioxide into the atmosphere, damage property, and lead to health issues. With climate change, forest fires are expected to increase in both frequency and intensity in
3:12-regelverket reglerar utdelning och kapitalvinst vid försäljning av aktier från ett fåmansföretag. Ett fåmansföretag har ett fåtal delägare som har beslutanderätt i företaget. Definitionen av ett fåmansföretag kan även uppfyllas i företag med flera delägare då dessa, under vissa förutsättningar, kan anses som en enda. Genom åren har 3:12-regelverket genomgått flera förändringar efter att ha anThe 3:12-rules regulate dividends and capital gains upon the sale of shares in a close company. A close company has a small number of shareholders who have decision rights in the company. The definition of a close company can also be fulfilled in companies with several shareholders as these, under certain conditions, are considered as one single shareholder. Over the years, the 3:12-rules have und
Land degradation and soil erosion are considered one of the main threats to ecosystem services and functions, soil stability and activity, plant community structure and biodiversity, and overall life on Earth. Soil erosion is a problem occurring all over Iceland, with an immediate urgency on the Icelandic highlands and rangelands. Currently, over 40% of the country is eroded, steadily causing loss
I entreprenadformen totalentreprenad upphandlar entreprenören konsulten och har därmed ansvar för både projektering och utförande. För att öka produktiviteten och innovationsgraden i järnvägsprojekt ökade Trafikverket antal projekt upphandlade som totalentreprenader mellan år 2012 och 2018. Det skapade en stor ovana för aktörerna i sättet att arbeta. Idag har företagen i järnvägsbranschen vant sigIn design-build contracts the contractor purchase the consultant and is therefore responsible for both design and execution. To increase productivity and innovation in railway projects Trafikverket, Swedish Transport Administration, increased the number of design-build contracts between 2012 to 2018. This created large unfamiliarity in the way of working for the actors. Today the companies in the
Background: Glioblastoma is the most common primary malignant brain tumor in adults. Elevated interstitial fluid pressure (IFP) within the tumor restricts drug uptake and contributes to the dismal prognosis. Antisecretory factor (AF) is an endogenous protein that possesses antisecretory and immunomodulating properties. In vivo, AF can reduce elevated IFP. There are two AF-enhancing products; Salov
Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others. The range of exper
Abstract Title: Project managers – The invisible leaders Authors: Stefan Karlsson and Christoffer Karlsson Supervisor: Radhlinah Aulin, Division of Construction Management, Lund Faculty of Engineering Problem: * What are the most important work tasks for a project manager * What are the most important skills in the role as a project manager * What kind of common problems and difficulties are a pro
The aim of this master thesis is to provide an indication of the suitability, or otherwise usage, of spray-drying for production of powder aimed for inhalation formulation and comparing the characteristics of the product, with and without lipids. Lipids have a proven effect of delaying release of active drug substances in the cardiovascular system and pulmonary systemic delivery has a number of ad
Attitudes towards littering A study of residents’ attitudes towards littering in public spaces in Malmö city All forms of littering are considered a crime according to the chapter 15 § 30 of the Swedish Environmental Code. Still, littering is considered an increasing rather than a decreasing phenomenon. The results of littering are not just esthetical nuisance and increased street cleaning costs b
The present thesis, adopting the ecology of language as its conceptual orientation as well as employing linguistic landscape as its methodological tool to collect and analyze data, firstly aims at investigating (1) how the four official languages of Singapore namely Malay, (Mandarin) Chinese, Tamil, and English have been deployed on signs by three different social actors, i.e., the Singaporean gov
AIMS: Experiencing an acute myocardial infarction (AMI) is a life-threatening event and use of statins can reduce the probability of recurrence and improve long term survival. However, the effectiveness of statins in the real-world setting may be lower than the reported efficacy in randomized clinical trials. Therefore, we aimed to investigate whether low statin treatment adherence during the year
Background: For a significant proportion of the older population, increasing age is associated with health problems and worsening health. Older family caregivers are largely responsible for care of next-of-kin living at home, which impacts their own physical and mental health both positively and negatively. However, evidence is insufficient regarding the health situation of older caregivers. The a
Background: Intracoronary pressure wire measurement of fractional flow reserve (FFR) provides decision-making guidance during percutaneous coronary intervention (PCI). However, limited data exist on the effect of FFR on long-term clinical outcomes in patients with stable angina pectoris. Objectives: The purpose of this study was to determine the association between the usage of FFR and all-cause m
Background: Recent clinical findings suggest that oxytocin could be a novel treatment for migraine. However, little is known about the role of this neuropeptide/hormone and its receptor in the trigeminovascular pathway. Here we determine expression, localization, and function of oxytocin and oxytocin receptors in rat trigeminal ganglia and targets of peripheral (dura mater and cranial arteries) an
BACKGROUND: A substantial proportion of cancer driver genes (CDG) are also cancer predisposition genes. However, the associations between genetic variants in lung CDGs and the susceptibility to lung cancer have rarely been investigated. METHODS: We selected expression-related single-nucleotide polymorphisms (eSNP) and nonsynonymous variants of lung CDGs, and tested their associations with lung can
