Utvecklingen av mer energieffektiva byggnader handlar idag till stor del om att använda mindre energi än gällande byggnormskrav. Ett sätt att bemöta de ständigt hårdare energikraven är att utnyttja byggnaders värmelagrande förmåga. För att kunna utnyttja en byggnads värmelagringsförmåga optimalt bör en tung stomme bestående av tegel, lättbetong, betong eller annat stenmaterial väljas, då dessa harThe development of more energy-efficient buildings is today mostly a matter of using less energy than current building norms requirements. A means of responding to the ever-tighter energy requirements is to make use of the energy-storing ability. In order to fully utilize a building's energy-storing ability, a heavy frame composed of brick, concrete, lightweight concrete or other stone materia
The increasing competition for water resources requires a better understanding of flows, fluxes, stocks, and the services and benefits related to water consumption. This paper explains how public domain Earth Observation data based on Moderate Resolution Imaging Spectroradiometer (MODIS), Second Generation Meteosat (MSG), Tropical Rainfall Measurement Mission (TRMM) and various altimeter measureme
Popular Abstract in English Peter is a part-time cocoa farmer who produces cocoa beans that are used for chocolate production. However, he has always wondered about the efficient utilisation of the residual cocoa pods, which seem to contain sugar as they attract bees. He discussed this with a student studying a biological process whereby organic material can be converted to biogas and a residue thThe replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). However, it has not yet been widely implemented on a large scale. Biohydro
Stålindustrin är den industrisektor som har högst utsläpp i världen. Ståltillverkning tillskrivs cirka 8 % av världens totala C02-utsläpp. Från den utgångspunkten är behovet av djup avkarbonisering av stålindustrin är uppenbart. Det mest gynnsamma alternativet för att fasa ut fossila bränslen från produktionen av stål är att övergå till ståltillverkning från grönt väte. I denna rapport undersöks kThe steel industry is the most emitting industry sector in the world. Steelmaking attributes to around 8 % of the world’s total CO2 emissions. From that standpoint the need for deep decarbonization in the steel industry is evident. The most viable option for removing fossil fuels from the production of steel is to move to steelmaking from green hydrogen. In this report comparative advantages for g
Accurate prediction on the pressurized discharge performance is significant to the safety operation of cryogenic propellant system. In the present study, a two-dimensional numerical model is established to simulate the fuel outflow with high-temperature gas injection. Both the environmental heat invasion and interfacial phase change are detailedly considered. The volume of fluid method is used to
Division of Building Physics The Division's research is about Theoretical and Practical Building Physics as well as the application of the subject through the development of Building Technology. The primary purpose is to combine building materials into well-functioning building components and buildings that are healthy for people to stay in for a long time. In order to have a sustainable society,

The European Spallation Source (ESS) has launched a project called HighNESS, with the task of investigating the potential of adding a second moderator system to the facility, with ortho-deuterium (o-D2) being the main material of interest. Another moderator material which could be of interest is hydrogen deuteride (HD). The purpose of this second moderator system would be to provide a high intensi
This thesis describes the use of bicyclo[3.3.1]nonane and its heteroanalogue 1,5- diazabicyclo[3.3.1]nonane as scaffolds in different supramolecular systems. The thesis is divided into two parts, with the first part (chapter 2–4) focusing on the development and applications of a synthetic receptor based on a Tröger’s base motif fused with 18-crown-6 moieties. In chapter 3, NMR titration methodolog

Generation of 15 monoclonal antibodies (MAbs) allowed construction of epitope maps and specific two-site immunofluorometric assays for free prostate-specific antigen (PSA) and PSA complexed with alpha 1-antichymotrypsin (ACT). Close correlation of PSA concentrations obtained with the use of different assays of free PSA suggested extensive similarity in immunodetection of free PSA in serum. Assays
The SET theory implies that energy is transferred from the catalyst system via infrared radiation to the molecules that are supposed to react. In previous investigations it has been demonstrated that the activation of the reacting species-as long as the molecules are infrared active-can occur at low adsorption strength. However, for molecules that are IR inactive, e.g. dinitrogen, this is not poss
Due to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons. This, together with the high reactivity, makes an efficient ventilation system very important in hydrogen applications. There are several models available for ventilation sizing that are based on either a well-mixed assumption or a fully stratifDue to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons.

Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym

Earlier work has derived the storage complexity of the bounded distance decoder (BDD) for binary-channel convolutional codes. We extend this work to the Gaussian noise channel and to partial-response codes. We show that the storage requirement similar to(2(1-R) - 1)(-t) paths for rate-R convolutional codes over the binary channel becomes similar to2(2Rt) over the Gaussian channel, where the decode
