  4. 2. Short term water heat storage : studies of velocity and temperature fields and their importance for sizing of the storage

    Author : Jan Dahl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Short term water heat storage's have been introduced in many district heating systems. The main reason for this is the possibilities opened by the storage for optimization of the generation of heat and electricity in combined heat and power plants. READ MORE

  5. 3. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

    Author : Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE

  6. 4. District heating system analysis and challenges within the urban transformation of Kiruna

    Author : Mattias Vesterlund; Jan Dahl; Henrik Saxen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; analysis; optimization; design; heat production; Energy Engineering; Energiteknik;

    Abstract : There is currently an ongoing urban transformation in a small Swedish town named Kiruna, it is located in the very north of Sweden well above the Arctic Circle in a sub-arctic climate. Large part of the town will be relocated due to the ground deformation that is caused by the progressing iron ore mining activity and it is affecting all infrastructures of the town. READ MORE

  7. 5. Development and Application of Human Chromosome 22 Genomic Microarray : Chromosome 22-Associated Disorders Analyzed by Array-Based Comparative Genomic Hybridization

    Author : Magdalena Benetkiewicz; Jan Dumanski; Niklas Dahl; Frank Speleman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; DNA copy number changes; chromosome 22; genomic microarray; array-CGH; schwannoma; neurofibromatosis type 2; ovarian carcinoma; breast cancer; Wilms tumor; Genetik; Genetics; Genetik;

    Abstract : The array-based form of comparative genomic hybridization (array-CGH) is a new methodology that has shown to be of significant importance. This thesis focuses on the development of array-CGH with the aim to define candidate regions/genes on chromosome 22 in a wide spectrum of cancer-related conditions. READ MORE
