1. 1. Long-acting reversible contraception (LARC) after pregnancy and childbirth

   Författare :Karin Lichtenstein Liljeblad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background and aims: Unmet need of contraception is a global challenge. The need of additional visits to initiate contraception is found to be a barrier for postpartum and postabortion contraceptive care. The IUDs and the implant are called long-acting reversible contraception (LARC). LÄS MER

3. 2. Theoretical Studies of Two-Dimensional Magnetism and Chemical Bonding

   Författare :Oleksiy Grechnyev; Olle Eriksson; Alexander Lichtenstein; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; spin Hamiltonians; quantized spin models; Heisenberg model; spin waves; self-consistent spin-wave theory; dipolar interaction; density functional theory; chemical bonding; overlap population; MAX phases; metal hydrides; Fysik; Physics; Fysik;

   Sammanfattning : This thesis is divided into two parts. In the first part we study thermodynamics of the two-dimensional Heisenberg ferromagnet with dipolar interaction. This interaction breaks the conditions of the Mermin-Wagner theorem, resulting in a finite transition temperature. LÄS MER

4. 3. Correlated Electronic Structure of Materials : Development and Application of Dynamical Mean Field Theory

   Författare :Patrik Thunström; Olle Eriksson; Alexander Lichtenstein; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; DMFT; correlation; entanglement; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : This thesis is dedicated to the development, implementation and application of a combination of Density Functional Theory and Dynamical Mean Field Theory. The resulting program is shown through several examples to be a powerful and flexible tool for calculating the electronic structure of strongly correlated materials. LÄS MER

5. 4. Laparoscopic or Open Inguinal Hernia Repair - Which is Best for the Patient?

   Författare :Arne Eklund; Claes Rudberg; Agneta Montgomery; Leif Bergkvist; Jacob Rosenberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inguinal hernia; TEP; Lichtenstein; convalescence; recurrence; chronic pain; cost-minimisation; Surgery; Kirurgi; Kirurgi; Surgery;

   Sammanfattning : Inguinal hernia repair is the most common operation in general surgery. Its main challenge is to achieve low recurrence rates. With the introduction of mesh implants, first in open and later in laparoscopic repair, recurrence rates have decreased substantially. LÄS MER

7. 5. Male inguinal hernia repair with mesh. Short- and long-term results and the question of infertility

   Författare :Magnus Hallén; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hernia repair; groin hernia; inguinal hernia; Lichtenstein; TEP; mesh; male infertility;

   Sammanfattning : Background: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery.
