A process combining dark fermentation and photofermentation for production of hydrogen is interesting due to its potential of producing hydrogen at a high yields. In this study, the hydrogen process is compared to a 2nd generation ethanol process with respect to cost and with the aim of increasing our understanding of the pros and cons and giving a clear picture of the present status of the two pr

Fuel cells are hopeful for future energy systems, because they are energy efficient and able to use renewable fuels. A coupled computational fluid dynamics approach based on the finite element method, in three-dimensions, is used to illustrate a planar intermediate-temperature solid oxide fuel cell. Governing equations for momentum, gas-phase species, heat, electron and ion transport are implement

To meet EU energy and climate targets, energy efficiency of the existing building stock must be drasticallyimproved. Within IEA ECB Annex 56 one of the best practice energy renovations is a group of multi-familybuildings in Sweden, recently thoroughly renovated. Residents' perception of renovations and appraisal ofimplemented measures were captured by interviews with tenants and a literature revie

Long term evaluation of an asymmetric CPC PV-thermal hybrid built for high latitudes, MaReCo (MaximumReflectorCollector), is performed in Lund, lat 55.7o, and this paper discusses output estimates and characteristics of the system. The output estimates are calculated using the MINSUN simulation program. To get the input for MINSUN, measurements were performed on two MaReCo prototypes. These measur

The aim of the study was to evaluate, from a technical and economic standpoint, the enzymatic processes involved in the production of fuel ethanol from softwood. Two base case configurations, one based on simultaneous saccharification and fermentation (SSF) and one based on separate hydrolysis and fermentation (SHF), were evaluated and compared. The process conditions selected were based mainly on

Massive MIMO (MaMI) is often promoted as a technology that will enable the use of low-quality, cheap hardware. One particular component that has been in the focus of MaMI-related research is the analog-to-digital converter (ADC), and use of very low-resolution ADCs has been proposed. However, studies about whether this strategy is justified from an energy-efficiency point of view have largely been

Alkaline membrane fuel cells can operate using nonprecious metals as catalysts, but rely on polymeric membranes with high hydroxide conductivity and alkali-resistance, which are hard to find. A new membrane is now reported comprising ferrocenium cations in magnetically aligned domains with an excellent combination of these properties.

Konstnärliga fakulteten bedriver forskning vid Inter Arts Center samt de tre institutionerna, med inriktning konst, teater och musik. Här bedrivs forskning inom ämnet fri konst, teater, musik och musikpedagogik. Forskningen kännetecknas av olika former av kunskap och influeras av många olika områden. Fakulteten samarbetar även med andra konstnärliga lärosäten i landet kring forskarutbildning för dResearch at the Faculty of Fine and Performing Arts are carried out at the Inter Arts Center and the three academies: art, theatre, and music. The faculty conducts research in fine art, theatre, music, and music pedagogy. Research in the fine and performing arts is characterized by diverse forms of knowledge and influences from many different areas. The Faculty of Arts also collaborates with other

Avdelningen Studentstöd och lärande ger service och stöd till studenter och består av tre arbetsgrupper: Pedagogiskt studentstöd, Studieverkstaden och SI-verksamhet.Student Support and Learning provide service and support to students, and comprises three working groups: Disability Support Services, the Academic Support Centre, and the Supplemental Instruction unit.

Handelsrätt är ett juridiskt ämne, som handlar om de regler och normer som har betydelse för ekonomisk verksamhet, nationellt såväl som internationellt. Handelsrätten reglerar företagens verksamhet och är alltså den samlande beteckningen på de olika delar av juridiken som är speciellt viktiga för företaget. Hit räknas t ex avtalsrätt, bolagsrätt, skatterätt, arbetsrätt, immaterialrätt och konkurreBusiness law is a legal discipline focused on the norms and rules that impact the business sector, both nationally in Sweden and internationally. Business law regulates companies’ operations and is an umbrella term covering the braches of law that are especially important for businesses. This covers, for example, contract law, corporate law, tax law, labour law, intellectual property law and compe

This work concerns reduction of the peak flow rate of a district heating grid,a key system property which is bounded by pipe dimensions and pumpingcapacity. The peak flow rate constrains the number of additional consumersthat can be connected, and may be a limiting factor in reducing supplytemperatures when transitioning to the 4th generation of district heating.We evaluate a full year of operatio

As the total cost of renewable electricity falls lower than the price of fossil fuel, not only can electricity be used to replace fossil fuels using batteries in vehicles but it can also be used to produce fuels. This makes it possible to replace fuels in sectors not easily directly electrified. It also provides new ways of balancing the electricity system. When renewable electricity is cheap a lo

Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose

Studying the effects of the climate change on buildings contains two major fields: energy consumption and durability. In the field of durability the moisture effects on the building play a significant role. In Sweden the last 10-15 years have been mild and wet compared to previously. Precipitation increased considerably during the period (+11 %), whereas temperature increase were weaker (+ 0.7 oC)

Denna uppsats undersöker de sedvanerättsliga reglerna om immunitet för statschefer och andra högt uppsatta statsrepresentanter. Syftet är att göra en övergripande kartläggning av reglernas innehåll som möjliggör korrekt rättstillämpning i framtiden. Genom att granska konventioner, kodifieringar, rättsfall och doktrin om ämnet, samt genom att undersöka det pågående kodifikationsarbetet, kartläggs rThis essay examines the rules of immunity for heads of state and other high-ranking state officials under international law. The aim is to create a comprehensive outline of the content of the rules, enabling a more accurate and legal-ly sound practice in the future. Through reviewing conventions, codifications, legal cases and legal doctrine on the subject, and through examining the current codi
