  2. 1. Nutritional Value and Quality of Processed Mango Fruits

    Author : Isabel Guiamba; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidification; ascorbic acid oxidase; polyphenoloxidase; water blanching; β-carotene; osmotic dehydration; infrared heating; microwave heating; Mango; EDTA; vitamin C;

    Abstract : Mango (Mangifera indica L.) is one of the most important tropical fruits commercialized and consumed worldwide, and an excellent source of fibre, bioactive compounds such as pro-vitamin A carotenoids, vitamin C (ascorbic acid) and phenolics. Mango was used in this thesis as a model fruit of fruits and vegetables that are rich sources of nutrients. READ MORE

  4. 2. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Author : Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Abstract : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. READ MORE

  5. 3. Energy Efficient Window Systems. Effects on Energy Use and Daylight in Buildings

    Author : Helena Bülow-Hübe; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; thermal transmittance; solar energy transmittance; shading device; solar protection; cooling; heating; energy demand; building; low-emittance coating; window; glazing; comfort; user aspects; operative temperature; Architecture; Building construction; Byggnadsteknik; daylight; perception; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Abstract : This thesis deals with energy-efficient windows in Swedish buildings. Parametric studies were performed in the dynamic energy simulation tool Derob-LTH in order to study the effects of window choices on energy use and indoor climate for both residential and office buildings.

  6. 4. Development of a non-destructive field testing method for thermal assessment of district heating pipes

    Author : Peter Lidén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat losses; thermal status; valve; polyurethane; cooling method; non-destructive testing; thermal conductivity; district heating network;

    Abstract : The thermal state of a district heating (DH) network governs the heat losses. It is a parameter considered if a change is to be made in the network. Heat losses are costly and economic aspects are important when planning for the maintenance or replacement of DH pipes. READ MORE

  7. 5. Assessment of novel applications for nano-porous thermal insulation in district heating pipes and building walls

    Author : Axel Berge; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive façade; nano-porous insulation; thermal insulation; district heating pipes; hybrid insulation;

    Abstract : In nano-porous thermal insulation there is a strong relation between the pressure and the thermal conductivity, even at pressures close to atmospheric pressure. This thesis presents research on applications of nano-porous insulation in hybrid insulation district heating pipes and in building walls. READ MORE
