The semiarid Punata alluvial fan is located in the central part of Bolivia. The main activity of this region is the extensive agriculture, and groundwater is the main water supply. Local villagers who use groundwater reported that in some places groundwater has a salty taste. In order to investigate the origin of this problem, several TEM soundings were performed in the study area, and they were c
Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legisl
Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method
Abstract In the field of occupational hygiene much consideration is devoted to the uptake through the human airways, but there are also reports of irritations, complaints and hazards or potential hazards due to particle deposition onto the eyes. There is a need for data regarding the dependence of the deposition rate on particle size and environmental parameters in order to formulate sampling crit
Jet shapes have been measured in inclusive jet production in proton-proton collisions at root s = 7 TeV using 3 pb(-1) of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-k(t) algorithm with transverse momentum 30 GeV < p(T) < 600 GeV and rapidity in the region vertical bar y vertical bar < 2.8. The data are corrected for detector effects and compared to seve
Abstract Clinical measurements are necessary in many routine follow-ups and scientific evaluations, but the accuracy of these measurements is seldom challenged. The size of the reconstructed ear is one important parameter in the follow-up regarding patients operated on due to microtia. With the introduction of digital morphometry one was obliged to evaluate its accuracy in comparison to its analog
In ST-elevation myocardial infarction (STEMI), thrombus material is often present in partial or total coronary occlusion of the coronary vessel. However, prior to the thrombus aspiration during ST-Segment Elevation Myocardial Infarction in Scandinavia (TASTE) trial, it remained unclear whether routine thrombus aspiration during percutaneous coronary intervention (PCI) treatment of STEMI would resu
Malawi är ett land i södra Afrika och betraktas som ett av de fattigaste länderna i världen. Befolkningen lever framför allt på landsbygden och är helt beroende av jordbruk för att överleva. Det finns dock inga register och ingen säkerställd rättighet över marken de brukar. Användandet av geografiska informationssystem, GIS, ökar runt om i världen. Hos ett jordbrukskooperativ i Malawi, NASFAM, fiMalawi is a country in southern Africa and considered to be one of the poorest countries in the world. The main part of the population lives in rural areas and is completely depending on farming for their livelihood. There are, however, no records of land registration or tenure for the smallholder farmer. The use of geographical information systems, GIS, is increasing around the world. At a small
The aim of this study was to examine if simplified linear analysis can be used to capture the complex and non-elastic behaviour that filled rubber exhibits. Linear analysis includes both linear elastic material models and a linear solving technique. The studied part in this thesis was a hose, connecting the air-inlet and turbo in a Scania truck engine. The studied material was a filled EPDM-rubber
Den här uppsatsen handlar om de förändringar på bästa tillgängliga teknik, d.v.s. BAT, som implementeringen av industriutsläppsdirektivet (IED) har inneburit. Syftet är att diskutera hur och på vilket sätt BAT har utvecklats i Sverige till följd av IED. BAT tillhör de allmänna hänsynsreglerna vilket gör den central vid all form av yrkesmässig verksamhet. I sammanhanget är principen om BAT tillämpThis thesis regards the changes to Best Available Techniques, BAT, which the implementation of the Industrial Emissions Directive, IED, has brought on. The purpose is to discuss how and in which ways BAT has developed in Sweden as a result of IED. BAT belongs to the general rules of consideration which makes it central in all forms of professional operation. In context the principal of BAT is app
The objective of this thesis was the impact evaluation of several parameters affecting daylight conditions in a typical cellular office in Lund, Sweden. The research approach that was followed consisted of three distinct steps; the literature review in order to specify the dependent and independent variables of the study, the simulation part to produce daylight performance data and the graphical a
The design of an axial compressor is mainly the trade-off between efficiency, stability and cost. A parameter that affects all of these three aspects is the blade aspect ratio. Due to the intricacy and complexity of the flow in a compressor, solely the effect of the blade aspect ratio variation is difficult to obtain. A parameter that supposedly is a gauge of the combined airfoil and end wall loa
Under åren 1965-1974 genomfördes en omfattande bostadsproduktion i Sverige som betecknas miljonprogrammet. Då byggdes en miljon bostäder runtom i landet. Idag finns behov av att renovera dessa bostäder. I samband med det kan energisparåtgärder genomföras för att minska energianvändningen. Detta kan uppfyllas genom att åtgärda otäta väggar och byta ut äldre fönster som medför oönskade värmeförlusteIn order to maintain a good indoor environment, air pollutants such as moisture need to be removed by the ventilation. Among the Swedish Public Health Agency's general advices for ventilation and indoor environment, 3 g/m3 is a guideline value for moisture excess during winter months to not pose a risk to human health. The indoor climate parameters moisture excess, relative humidity and air va
The order-to-delivery (OTD) process for a specific product group at ASSA ABLOY Entrance Systems (AAES) has been underperforming lately and failing to meet changing customer expectations, especially regarding reliability and speed. The current process configuration has been assessed as outdated and inadequate for efficient distribution of the product. Since the OTD process was configured, supply ch
The main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated

The rapid development of generative AI systems such as large language models (LLMs) and image generators have revealed critical tensions between technological innovation and existing data protection frameworks. This thesis examines the practical challenges related to the right to erasure established in Article 17 of the GDPR, commonly known as the "right to be forgotten" in the context o
”Hwart hjerta andas krig”: an analysis of the depiction of war in Skillingtryck 1770–1830. Even though modern Swedish history has been distinctively peaceful, with the country not having been at war since 1814, the Swedish prime minister Ulf Kristersson stated in January 2025 that Sweden, while not at war, is not at peace. Since conceptualizations of war have varied throughout history, this thesis
Formulating and implementing agricultural policies are important for the development of the agricultural sector and the rural population. The process of policy making is a political bargain between politicians and citizens. The outcome of this process, the policies, cannot be expected to be Pareto efficient resource allocations since altruistic behaviour is not very likely. All participants in the
Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter. Plotting these stars as [C/O] vs [O/H], it is revealed
