  1. 6. Silicon neural interfaces -Design and biomedical aspects-

    Författare :Lars Wallman; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Sammanfattning : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  4. 8. The Symmetric Meixner-Pollaczek polynomials

    Författare :Tsehaye Araaya; Sten Kaijser; Svante Janson; Hjalmar Rosengren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Meixner-Pollaczek polynomial; Orthogonal polynomial; Polynomial operator; Inner product; Umbral calculus; Sheffer polynomial; Convolution type polynomial; Connection and linearization problem; 33C45; 05A40; 33D45; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

    Sammanfattning : The Symmetric Meixner-Pollaczek polynomials are considered. We denote these polynomials in this thesis by pn(λ)(x) instead of the standard notation pn(λ) (x/2, π/2), where λ > 0. LÄS MER

  5. 9. Classifying Lattice Polytopes

    Författare :Anders Lundman; Sandra Di Rocco; Diane Maclagan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two papers in toric geometry. In Paper A we provide a complete classification up to isomorphism of all smooth convex lattice 3- polytopes with at most 16 lattice points. There exist in total 103 different polytopes meeting these criteria. LÄS MER

  7. 10. The impact of nutrition on growth, biomarkers, and health outcomes in preterm infants

    Författare :Cornelia Späth; Magnus Domellöf; Elisabeth Stoltz Sjöström; Deborah O’Connor; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm infant; parenteral nutrition; energy intake; nutrient intakes; postnatal growth; electrolyte imbalances; sodium supply; hypernatremia; intraventricular hemorrhage; pediatrik; Pediatrics; Nutrition; näringslära;

    Sammanfattning : Introduction: Nutrients play a crucial role for growth and brain development after preterm birth. Meeting the nutritional needs of preterm infants is challenging. Particularly, the most immature infants have a high risk of malnutrition and poor growth during hospital care. LÄS MER
