Biofilm som bildas på materialytor vanligt förekommande i processutrustning inom livsmedelsindustrin utgör ett hot mot livsmedlets säkerhet och kvalitet. Bakterier som närmar sig en yta kan fästa in, föröka sig och skapa en matris av extracellulära polymersubstanser (EPS) vilken de bäddar in sig i. Biofilm som väl etablerats är svår att tvätta bort och det är därför av intresse att undersöka faktoBiofilms formed on surfaces encountered in process equipment in the food industry pose a threat to food safety and quality. Planktonic bacteria can adhere to a surface, proliferate, and embed themselves in a matrix of extracellular polymeric substance known as the EPS. Because biofilms are difficult to remove once established, factors influencing the initial attachment is of interest to investigat

Sedan Sveriges etikprövningslag började gälla år 2004 har kritiken mot den varit omfattande. På senare år har debatten kring lagen varit extra intensiv, och kritiken kommer framför allt från forskare inom samhällsvetenskap, rättsvetenskap och humaniora. Kritiken mot lagen och Sveriges etikprövningssystem går i första hand ut på att etikprövningslagen försvårar vissa typer av forskning till den graThe Swedish Act (2003:460) concerning the ethical review of research involving humans (“Ethical Review Act”) has been widely criticized since its introduction. In the latest years the debate has been intensive, with critique from researchers in social studies, law and humanities. The critique is primarily implying that the Swedish Ethical Review Act aggravate certain types of research to that exte

Ända sedan 1800-talet har det stått klart att för den som vill utforma termodynamiska processer finns det oundvikliga kompromisser. Bland de främsta av dessa är att för en värmemotor måste man välja mellan kraft eller effektivitet: en kraftfull motor kan inte vara effektiv, och en väldigt effektiv motor kan inte vara kraftfull. Detta var länge accepterat som en oundviklig konsekvens av termodynamiWe investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly

Sweden has seen a rise in firearm-related violence in recent years, and Malmö is one of three cities that has experienced a significant increase in these crimes. This study isolates the role of socioeconomic variables as determinants of firearm-related violence, exploring whether socioeconomic disadvantage independently influences the spatial distribution of these incidents in Malmö. The spatial c

Takskjutportarna är en del av den befintliga produktportföljen och finns i två olika tjocklekar, 42 och 82 mm. Dörrarna är uppbyggda av antingen panel- eller ramsektioner, eller en kombination av båda. Den 82 mm tjocka dörren används när det finns ett This Master Thesis, executed in collaboration with ASSA ABLOY Entrance Systems, aimed at developing a new frame section for industrial overhead sectional doors. The overhead sectional doors are a part of the existing product portfolio and exist in two different thicknesses, 42 and 82 mm. The doors are built up by either panel or frame sections, or a combination of both. The 82 mm thick door is use

In increasingly turbulent environments, intrapreneurship has proven to be a crucial factor for established companies’ success and survival, showing a positive impact on innovation and organizational performance. Despite the strong importance that current research attaches to entrepreneurial employees in existing corporations, there remains a very limited understanding of their decision-making. The

Syftet med denna rapport är att utvärdera brandsäkerheten på Confidencen som är belägen vid Ulriksdals slottspark i Stockholm. Rapporten är avgränsad till att undersöka personsäkerheten och målet är att ta fram troliga brandscenarier och utvärdera hur väl brandskyddet kan motstå dessa. Om inte en säker utrymning kan genomföras presenteras eventuella förbättringar i brandskyddet. Efter en grovrisThe following report is a fire safety evaluation regarding Confidencen at Ulriksdals slott. This report was delimited to investigate if a safe evacuation could be achieved for the visitors. The purpose was to define relevant fire scenarios and evaluate the fire protection in the building. Three different fire scenarios were chosen from a gross hazard analysis to be further investigated. The foll

Flera av dagens viktiga industriella processer är källor till stora mängder utsläpp och kräver enorma mängder energi. Det är allmänt känt att detta inte är ett hållbart produktionssätt och andra alternativ efterforskas. Det är viktigt att finna bättre lösningar för olika samhällskritiska processer, effektivt utnyttja befintliga resurser, minska utsläpp och energianvändning. Produktionen av kalciumThe current industrial method of producing calcium formate requires a lot of energy and releases vast amounts of carbon dioxide. However, it has been demonstrated that direct synthesis of calcium formate from calcium carbonate is possible via direct reaction with carbon dioxide by using catalysis. Furthermore, this possibility is of great interest since calcium carbonate is one of the main waste p

Uppsatsen har analyserat beskattning av inkomster från illegala verksamheter i förhållande till rättsliga principer. Rättspraxis visar att inkomster från verk-samheter med illegala inslag kan beskattas utifrån neutralitetsprincipen och likformighetsprincipen, där alla inkomster oavsett ursprung ska beskattas. Rättspraxis på området är dock inte entydig då domstolen i andra avgöranden har kommit tiThe essay has analyzed the taxation of income from illegal activities in relation to legal principles. Case law demonstrates that income from activities with illegal elements can be taxed based on the principles of neutrality and equality, where all income, regardless of origin, should be subject to taxation. Howev-er, case law in this area is not consistent, as courts in other rulings have con-cl

This thesis is focused on the investigation of the ultrafast structural response of the phase change material (PCM) Ge$_2$Sb$_2$Te$_5$ following laser excitation. Phase change materials are a group of materials capable of rapid, non-volatile, switching between an amorphous and a crystalline phase. The two phases exhibit high optical and electrical contrast, meaning the optical reflectivity and the

Dielectric metasurfaces are the state of the art of functional optical devices with light manipulating capabilities. Metasurfaces are planar devices which makes them highly efficient since they do not suffer from propagation effects. These devices consist of sub-wavelength dielectric structures arranged in a lattice, situated on a substrate of dielectric or metallic material. They have been shown

The purpose of this study is to analyze and theorize punk and to investigate how punk is being performed. But also to counter previous descriptions of punk as a subculture, counter-culture or field and present the outline to a theory of scene. The question at issue in this study is: how can punk be described theoretically? This study is divided into acts. The first act introduces the reader to th

The aim of this study was to investigate and gain a deeper understanding of how the staff at the youth clinic approaches, and might influence, participation and responsibility as regards the girl and boy respectively in the process that follows when an unplanned pregnancy has been verified. Qualitative interviews were carried out with staff at five youth clinics in Skåne. All staff did routinely w

The purpose of this thesis is to analyze the possibilities and challenges of certification for obtaining sustainable tourism. On the basis of the purpose, I have designed two research questions. 1.Which are the possibilities of certification? 2.Which are the challenges of certification? My problem approach is descriptive and my aim with the thesis is to explain “how things are” at a certain time a

This thesis investigates the game of oil shipping; both the market settings and how the players play the game. An important characteristic of the oil shipping market is cycles in the spot freight prices. The cycles are created by the imperfect adjustment mechanisms of supply within the relatively short run, and by that the demand is not perfectly predictable. By a mathematical investigation, I sho

The GATT/WTO has not been covered in any of the compulsory subjects in the law programme, and there are no electives on the subject. This is something that should be made clear already at the outset, because it puts the thesis in the right perspective. Like all other law students, I knew nothing about the subject when I started to work on the thesis, and even now, my expertise only dates back a fe
