  2. 16. Traces of Hecke operators on Drinfeld modular forms via point counts

    Author : Sjoerd De Vries; Jonas Bergström; Gunther Cornelissen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drinfeld modules; Drinfeld modular forms; trace formula; Ramanujan bound; slopes; matematik; Mathematics;

    Abstract : In this licentiate thesis, we study the action of Hecke operators on Drinfeld cusp forms via the theory of crystals over function fields. The thesis contains one preliminary chapter, in which we recall some basic theory of Drinfeld modules and Drinfeld modular forms, as well as the Eichler-Shimura theory developed by Böckle. READ MORE

  5. 18. Cracking in Reinforced Concrete Structures Due to Imposed Deformations

    Author : Agnes Nagy; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum reinforcement; cracking; softening; shrinkage; cooling; imposed deformations; conversion formula; static E-modulus; damping coefficient; resonance frequency; dynamic E-modulus; constitutive model; thermal stress; hydration process; reinforced concrete structure; early age; crack control; Building construction; Byggnadsteknik;

    Abstract : This thesis is concerned with modeling of the cracking process in reinforced concrete due to imposed deformations. Cracking is investigated both at early ages, during hydration, and at mature age when the final properties of the concrete are reached. READ MORE

  7. 20. Promotion of Exclusive Infant Feeding in South Africa : Community-Based Peer Counselling in high HIV Prevalent Area

    Author : Barni Nor; Eva-Charlotte Ekström; Beth Maina Ahlberg; Lars Dahlgren; Uppsala universitet; []
    Keywords : Promotion; Exclusive Breastfeeding; Formula Feeding; Peer Counselling; HIV; South Africa; MEDICINE; MEDICIN; Medicin; Medicine;

    Abstract : Despite global efforts, exclusive breastfeeding is rarely practiced in South Africa where infants are at risk of diarrheal infections, malnutrition and HIV transmission. The present study was conceptualized within the context of a multi-country, cluster randomized community-based behavioural intervention known as PROMISE-EBF in South Africa, Burkina Faso, Zambia and Uganda (www.
