1. 6. The significance of sexuality and cyst formation in the life-cycles of four marine dinoflagellate species

   Författare :Rosa Figueroa; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyst; Hydrobiology; akvatisk ekologi; marine biology; aquatic ecology; limnology; sexuality.; meiosis; Lingulodinium polyedrum; life-cyle; limnologi; Marinbiologi; Gymnodinium nolleri; Gymnodinium catenatum; Alexandrium catenella; dinoflagellates;

   Sammanfattning : Sexuality and cyst formation were studied in the marine dinoflagellate species Gymnodinium catenatum Graham, Gymnodinium nolleri Ellegaard ? Moestrup, Alexandrium catenella (Whedon et Kofoid) Balech, and Lingulodinium polyedrum (Stein) Dodge. The study included the morphological characterization of sexual stages and processes, the time and description of meiosis, the study of the length and regulation of the mandatory dormancy period of resting cysts, and the relationships among parental strains and cyst progeny at phenotypic and molecular levels.

3. 7. Generating Dendritic Cells by Direct Cell Reprogramming. Merging cellular reprogramming with immunology towards the development of novel cancer immunotherapies

   Författare :Fábio Fiúza Rosa; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dendritic Cell; Direct Cell Reprogramming; Single-cell analysis; Immunotherapy;

   Sammanfattning : Cell fate reprogramming towards pluripotency or alternative somatic cell-types has highlighted the plasticity of adult somatic cells, providing new technologies to generate desired cell types for tissue repair or for disease modeling. There is momentum to bring these concepts to immunology by specifying unique immune cellular identities that set in motion immune responses. LÄS MER

4. 8. Engineering Saccharomyces cerevisiae for mixed-sugar fermentation

   Författare :Rosa Garcia Sanchez; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; evolutionary engineering; promoter; mixed-sugar utilization; galactose; arabinose; xylose; Saccharomyces cerevisiae; fermentation; ethanol; phosphoglucomutase;

   Sammanfattning : Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. LÄS MER

5. 9. Personas and Scenarios in Use

   Författare :Rosa Gudjonsdottir; Yngve Sundblad; Henrik Artman; Jonathan Grudin; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnographic fieldwork; multi-sited fieldwork; participant observation; user-centered design; user research; personas; scenarios; Computer science; Datalogi; Social anthropology ethnography; Socialantrolopologi etnografi;

   Sammanfattning : Personas are fictitious characters that represent the needs of the intended users, and scenarios complementing the personas describe how their needs can be met. The present doctoral thesis considers the usage of personas and scenarios and how they are used in system development projects. LÄS MER
