  1. 6. Reproducing kernels and potential theory for the Bergman spaces

    Författare :Yolanda Perdomo Gallipoli; Matematikcentrum; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; weighted biharmonic Green function Gaussian curvature; Naturvetenskap; harmonic compensator; Natural science; weighted super-biharmonic function; potential metric; mean value property; weighted Bergman kernel;

    Sammanfattning : The role of weighted biharmonic Green functions in weighted Bergman spaces was first studied in the beginning of the 50's by Paul Garabedian. In 1951 he showed that they are closely related to reproducing kernel functions of weighted Bergman spaces. LÄS MER

  3. 8. Bioprocess Monitoring and Control in Pseudomonas cepacia and recombinant Escherichia coli cultivations

    Författare :Anita Tocaj; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein L; expanded bed; flow-injection analysis; recombinant protein production; acetic acid; on-line measurements; Pseudomonas cepacia; recombinant Escherichia coli; Fed-batch cultivations; control strategies; xylanase deletion derivatives from Rhodothermus marinus; Biotechnology; Bioteknik;

    Sammanfattning : The control of cultivation conditions and its influence on growth and production have been investigated. The use of fed-batch processes have been demonstrated for several cultivation systems and so has the use of different control signals in these systems. LÄS MER

  4. 9. NMR Self-Diffusion Studies and Stability Studies of Emulsions

    Författare :Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

    Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER

  5. 10. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

    Författare :José da Cruz Francisco; Kemiska institutionen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

    Sammanfattning : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. LÄS MER
