  1. 1. Probing Control of Glucose Feeding in Escherichia coli Cultivations

    Författare :Mats Åkesson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; dissolved oxygen; acetate; glucose feeding; robotteknik; Escherichia coli; Process control; fed-batch cultivation; reglerteknik; Biotechnology; Bioteknik;

    Sammanfattning : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. LÄS MER

  4. 3. Ecology and conservation of the moth Dysauxes ancilla

    Författare :Per-Eric Betzholtz; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; marc-recapture; population viability; fluctuating asymmetry; genetic status; larval feeding; movements; endangered species; conservation; outpost population; Lepidoptera; Dysauxes ancilla;

    Sammanfattning : The ecology of the moth Dysauxes ancilla was studied in the only Swedish breeding area at Beijershamn, situated on the Baltic island of Öland. The population is a northern outpost, separated from the species´ continous distribution area in middle- and southeast Europe. LÄS MER

  5. 4. The Teddy Bear in Psychology : A prospective study with focus on children´s use of transitional objects

    Författare :Margareta Viberg; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychiatry; clinical psychology; psychosomatics; Development psychology; parent interview; child interview; development; follow up; pacifier use; thumbsucking; breast feeding; transitional object; transitional phenomenon; Psykiatri; psykosomatik; Utvecklingspsykologi; klinisk psykologi;

    Sammanfattning : The central issue of the dissertation is the place and meaning of the concepts transitional object (TO) and transitional phenomenon (TP) as defined by Winnicott, in a normal psychological context. A group of children were followed from age 8 months to 6 years. LÄS MER

  7. 5. A flying start : Adapted hatching and post-hatch feeding in broiler chickens

    Författare :Malin Boyner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Conventional hatching practices do not involve provision of feed and water to broiler chickens before placement at the rearing farm. This can pose problems, especially for early hatchlings, which remain feed-restricted for a considerable period due to biological variation in hatch time. LÄS MER
