The use of InP nanowires solar cells as a platform for the third generation concept of spectral conversion has been explored by embedding the Coumarin 120 dye between the nanowires of the solar cells. The InP solar cells have been characterised by measuring the external quantum efficiency, EQE, and the current voltage, JV, curve. For the EQE measurement an imaging system was constructed to constra
Engine lubrication is very important for engine sustainability and efficiency. It becomes even more important when heavier fuel types who contributes to lubrication are changed to alternative fuel without the same lubrication abilities. Because the performance of lubrication systems sometimes can be very hard to study in real time due to hostile environments inside engines, specialized techniques
Public participation is vital to ensure sustainable water management, and providing education is one of the way to trigger participation. For decades, developed countries try to educate their citizen to be environmentally literate, and for the water sector, water-related knowledge has been introduced to the public by schools, municipalities and water utilities. The condition is harder for developi
Manufacturing systems are becoming increasingly more complex at the same time as competition requires manufacturers to continuously improve their effectiveness and efficiency. The use of discrete event simulation to model manufacturing systems is well-established and generally considered to be the method of choice when analysing what-if scenarios. Simulation is currently predominantly applied when
Den här studien syftar till att undersöka, diskuterar och problematiserar hur politiska nätaktivister, så kallade clicktivister, mobiliserar och kommunicerar under en organisationskris. Studien tar sin utgångspunkt i fallet Bokmässan. Organisationens Facebooksida blev en plats för intensiv debatt när det blev känt att den högerpopulistiska tidningen Nya Tider skulle delta på mässan. Studien undersThe purpose of the study is to problematize and discuss the mobilization and communication of online-based activists, so-called “clicktivists”, in an organizational crisis. The study examines the case of the Gothenburg Book Fair, where the organization’s Facebook page became an arena for debate because of a far-right newspaper’s plans to attend the book fair. The study examines the discourses prod
This study explores the implications of an encampment policy - criminalising refugees’ mobility beyond the borders of a camp - for the potential of Cash Based Transfer assistance in protracted refugee situations. As the success of Cash Based Transfer assistance implies market availability and access to commodities, and certain interaction between the host community and refugee population, it is ar
Fog and clouds are difficult to predict for meteorologist today. Models have a tendency to show either too much or too little clouds or fog, which can be a problem for people and industries that depend on the weather conditions. Improvements are being done, but errors still occur. One of the problems is that when an improvement is attained, it might only work for one specific season. This happens,
För att avgöra huruvida en isälvsavlagring som enligt Sveriges Geologiska Undersökning (SGU) bedöms ha uttagsmöjligheter på >125 l/s väster om Finjasjön är lämplig som reservgrundvattentäkt till Hässleholms kommun utfördes en geofysisk undersökning. Mätningar utfördes med georadar, stångslingram med tre frekvenser samt resistivitetsmätning och inducerad polarisation (IP) i form av en CVES-mätning
About 25,3 % of the Mozambican population is suffering from undernourishment even though a sufficient amount of food and specifically fruits are produced. Post-harvest losses are estimated to 25 % to 40 % and part of the production is not even harvested due to a short season. A solution has to be found to improve fruit preservation and allow the population to consume what is harvested later. Dryin
Fysiska och juridiska personer är i någon form av förhållande med varandra baserat på olika omständigheter. När två parter är oense om en fråga vill de givetvis lösa situationen på något sätt. Denna lösning ligger för många hos statliga domstolar där den ena parten stämmer den andra parten vid tingsrätten som första instans. I vissa tänkta utfall är förhållandet baserat på ett avtal som parterna Natural and legal persons are in some form of relationship with each other based on different circumstances. When two parties disagree about an issue, they naturally want to resolve the situation in some way. For many, this solution lies with state courts where one party sues the other party at the district court as first instance. In some scenarios, the relationship is based on a contract that t
Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. In its current form, the catalyst rapidly deactivates, causing increased mat
Sverige är ett land med hög jämställdhet, men trots det finns det fortfarande brister inom arbetslivet vad gäller oönskade beteenden på arbetsplatsen. Lagen och regleringen är utspridd och inte helt enkel att förstå, vilket gör det svårt för arbetsgivare att aktivt arbeta för att motverka oönskade beteenden. Vidare ser trakasserier och sexuella trakasserier olika ut i olika branscher. Syftet med dSweden is a country with a high level of gender equality, but despite this there are still shortcomings in working life in terms of unwanted behaviour in the workplace. The law and regulation are scattered and not entirely easy to understand, which makes it difficult for employers to actively work to counter unwanted behaviour. Furthermore, it has been shown that harassment and sexual harassment l
Animals monitor environmental ques by translating them into electrical signals through a depolarization of the electric potential over the cell membrane of nerve cells. A way to initiate the depolarization is through activation of receptors that are ion channels. These channels can facilitate the diffusion ions across membranes driven by the differences in concentration and electrical charge on ea
Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging. The technique combines the resolution of ultrasound with the tissue contrast from light to image optical absorption in tissues. This report presents simulations analyzing how cha
Abstrakt. Bakgrund: Personer med schizofreni rör sig mindre än den generella befolkningen och har en ökad risk att dö i förtid till följd av sjukdomar som går att förebygga med fysisk aktivitet. Syfte: Att belysa vilka motiverande och hindrande faktorer som personer med schizofreni upplever påverkar deras val att genomföra fysiska aktiviteter. Metod: Studien var en empirisk kvalitativ intervjustud
Bakgrund: Svårigheter att upprätta en fullgod ventilation hos barn kan bero på många olika orsaker. Det kan bland annat bero på diagnoser som cystisk fibros, primär ciliär dyskinesi och multipla funktionshinder. Barnen kan behöva andningsvårdande behandling under stora delar av dygnet och föräldrar kan få kunskap och stöd från fysioterapeuter, men ansvarar sedan själva för att utföra behandlingen
The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability. The goal in this project is to develop a final drive device for torque vectoring in a small r
