  1. 1. Postoperative aspects of inguinal hernia surgery : pain and recurrences

    Författare :Niklas Magnusson; Gabriel Sandblom; Ulf Gunnarsson; Mats Hedberg; Marc Miserez; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inguinal hernia; surgery; pain; reoperation; recurrence; betamethasone; sensory disturbance; nerve; groin; Medicin; Medicine;

    Sammanfattning : Approximately one in four men will have surgery for ingunial hernia in their lifetime. In Sweden, 16 000 procedures are performed each year. To investigate the possible link between handling of nerves and sensory disturbance, 97 groins in 92 patients were examined one year after inguinal hernia surgery. LÄS MER

  4. 3. Polynomial Sequences Generated by Linear Recurrences : Location and Reality of Zeros

    Författare :Innocent Ndikubwayo; Boris Shapiro; Rikard Bögvad; Tamás Forgacs; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-rooted polynomials; generating functions; discriminants; Tran s conjecture; Toeplitz matrices; Mathematics; matematik;

    Sammanfattning : In this thesis, we study the problem of location of the zeros of individual polynomials in sequences of polynomials generated by linear recurrence relations.In paper I, we establish the necessary and sufficient conditions that guarantee hyperbolicity of all the polynomials generated by a three-term recurrence of length 2, whose coefficients are arbitrary real polynomials.

  5. 4. Topics in polynomial sequences defined by linear recurrences

    Författare :INNOCENT NDIKUBWAYO; Boris Shapiro; Rikard Bøgvad; Tamás Forgács; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recurrence relation; q-discriminant; generating function; polynomial sequence; support; real zeros; matematik; Mathematics;

    Sammanfattning : This licentiate consists of two papers treating polynomial sequences defined by linear recurrences.In paper I, we establish necessary and sufficient conditions for the reality of all the zeros in a polynomial sequence {P_i} generated by a three-term recurrence relation P_i(x)+ Q_1(x)P_{i-1}(x) +Q_2(x) P_{i-2}(x)=0 with the standard initial conditions P_{0}(x)=1, P_{-1}(x)=0, where Q_1(x) and Q_2(x) are arbitrary real polynomials.

  7. 5. Atrial fibrillation : clinical presentation and prevention of recurrences

    Författare :Anna Nergårdh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atrial fibrillation; arrhythmias; beta-blocker; cardioversion; symptoms;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained arrhythmia of clinical importance. AF is known to decrease quality of life and it is related to an increased morbidity and a risk of tromboembolic events. AF may also be asymptomatic, and to what extent patients actually are able to distinguish between sinus rhythm (SR) and AF is unknown. LÄS MER
