Time-resolved particle emissions from a conventional wood stove were investigated with aerosol mass spectrometry to provide links between combustion conditions, emission factors, mixing state of refractory black carbon and implications for organic tracer methods. The addition of a new batch of fuel results in low temperature pyrolysis as the fuel heats up, resulting in strong, short-lived, variabl
We report systematic transmission electron microscope (TEM) observations of the cellular ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different environments (intertidal mudflat, fjord, and basin) were investigated: Ammonia sp., Elphidium oceanense, Haynesina germanica, Bulimina marginata, Globobulimina sp., Nonionellina labradorica, Nonionella sp., Stainforthia
Generalized reaction classes for the consumption and decomposition of aldehydes, ketones, and olefins are described. These classes are important for generating not only reactions for the consumption of the branching agents of low-temperature hydrocarbon combustion but also reactions of the oxidation of alkenes and the decomposition of cyclic ethers. These reaction classes have been extrapolated fr
Expressed emotion (EE) is associated with relapse in adults with psychotic disorders. EE was assessed both at admission and after discharge with the Five Minutes Speech Sample (FMSS) in adolescent in-patients with psychotic disorders (n=15). The results showed that while neither admission nor post-discharge high-EE predicted relapse, the aggregated EE from admission or after discharge significantl
Recently it was discovered that composites of Terfenol-D alloys with an insulating binder produce very large magnetostrictions. Resistivities of these composites reach high values, making them attractive for high-frequency applications which require small eddy current losses. In this paper the magnetostriction, magnetization, and Young's moduli measurements made under constant magnetic field condi
When building below ground level in cities the regulations regarding deformations of surrounding soil are very strict. When using conventional methods of calculation it is difficult to predict the occurring deformations. This is why it has become more common to use FE-modeling to determine deformations. With FE-modelling it is possible to take the interactions between soil and construction into co
Våren 2020 tvingades svenska lärosäten att ställa om till distansundervisning på mycket kort varsel. Förutsättningarna var goda när det kom till datorvana och infrastruktur men det har funnits indikationer på att dataskyddet fått stå tillbaka. Uppsatsen syftar till att med hjälp av en rättsdogmatisk metod, reda ut och åskådliggöra de olika aktörernas ansvar och GDPRs tillämplighet vid distansunder
The aim of this thesis is to highlight what makes a good bicycle infrastructure with the goal to increase bicycling in urban areas. The focus has been to evaluate the bicycle infrastructure in the city of Lund, by investigating the differences between the main bicycle routes and the regular bicycle network in the city. A literature review of both scientific literature and bicycle planning manuals
In this thesis the automation of an optical sight validation process was studied. The goal was to find a solution for controlling the position of a red dot in a red dot sight. A red dot sight is a non-magnifying reflector sight in which the user sees a red dot instead of a reticle. The movement of the dot was performed by fastening and unfastening adjustment screws on the sight. A side goal was to
A laboratory creasing device to capture the most important properties of a commercial rotary creasing tool was designed. Finite element analysis of the creasing of a multiply paperboard in the laboratory crease device was presented. The multiply paperboard was modeled as a multilayered structure with cohesive softening interface model connecting the paperboard plies. The paperboard plies were mode
Northern high-latitude wetlands are well known to seasonally emit methane gas into the atmosphere, and therefore contribute to greenhouse effects. While these gas emissions are well documented, their causes are not well understood. The method described in this work can be used to analyze the changes happening in the soil during gas emissions, and therefore help the understanding of the sub-surfac
Since the gang rape of a physiotherapist student in Delhi 2012 the media reporting on sexual violence has increased by 30 percent. Several studies have looked at how media report on sexual violence in India, but very few have looked at the increased news reporting from a critical point of view. This thesis draws upon interview narratives collected in Delhi in February and March 2016 and looks at h
Since the legal reform and adoption of the new sex purchase act in 1999, the efficiency of governmental actions and continuance of social vulnerability among prostitutes/sex workers in Sweden have been recurring topics in public debate. Conflicting views on what the problem actually is and how it might best be dealt with, create a divide between those who advocate a liberal feminist perspective, a
This study addresses the question of economic and workplace related determinants and consequences of fathers’ parental leave use in Sweden. The analysis is based on the Swedish Level of Living Survey for the years 1991 and 2000. The results show that wages and the probability of taking parental leave beyond the ‘daddy month’ are inversely u-shaped: with very low hourly wages it does not seem to be
This Master Thesis has been carried out for Dresser Wayne AB in Malmö, done at the Division of Machine Design, Department of Design Science at LTH, Lund’s Univer-sity. Dresser Wayne was interested in finding a new or improved flowmeter for their fuel-dispensers since the two current flowmeters were either expensive or having drift problems. Dresser Wayne also had their own idea of replacing the pi
Dividends effect on stock prices and shareholders return is a disputed subject in finance. The purpose of this thesis is to expand on the existing research both the effect of dividends in general and on stocks on the Swedish market in particular. This thesis establishes an index of stocks with 5 or more years of dividend growth for at least the last 5 years on the Swedish market, by comparing this
The problems of de-blurring, de-noising, compression and segmentation are fundamental problems in image processing. Each of these problems can be formulated as a problem to find some approximation of an initial image. To find this approximation one needs to specify the approximation space and in what space the error between the image and its approximation should be calculated.Using the space of Bo
Den territoriellt förankrade politiken har sin grund i suveränitetsprincipen som idag alltmer får stå tillbaka för de globala förändringsprocesser som har präglat vår omvärld de senaste decennierna. Judikaliseringen är en av dessa processer där allt fler politiskt viktiga frågor avgörs av domstolar och andra judiciella organ istället för av politiska instanser. När normer som demokrati och mänskliThe foundation of territorially legitimated politics lies in the principle of sovereignty. These have been forced to retreat/stand back to the global processes of change, which have been shaping the world around us during recent decades. One of these processes is judicalization where an increasing number of politically important questions are determined by courts and other judicial organs rather t
The purpose of this study is to show and discuss the work and the efforts that are made for children and young asylum seekers in the Swedish society, focusing on the rights of the child. My aim was also to discuss whether Sweden complies with the Convention on the rights of the child in asylum cases. My questions were: What rights do children and young asylum seekers have compared to adults? How a
