    Sammanfattning : In a cubic multigraph certain restrictions on the paths are made to define what is called a railway. Due to these restrictions a special kind of connectivity is defined. As the number of vertices tends to infinity, the asymptotic probability of obtaining an, in this sense, connected random cubic multigraph is shown to be 1/3. LÄS MER

  2. 2. Some Cases of Kudla’s Modularity Conjecture for Unitary Shimura Varieties

    Författare :Jiacheng Xia; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; special cycles; Eisenstein series; spherical designs; central L-values; unitary Shimura varieties; Jacobi forms; rational points; generating functions; the circle method; Kudla s modularity conjecture; theta series; Rankin--Selberg method;

    Sammanfattning : A common theme of the thesis is the interplay of symmetry and rigidity, which is a general phenomenon in mathematics. Symmetry is a notion related to the degree to which an object remains unchanged under transformations, and rigidity is a notion that in terms of physics can be thought of as a lack of freedom, which leads to stronger properties of an object than we normally expect.

  3. 3. Climacteric Symptoms and Hormonal Treatment with special reference to Sequential Transdermal Therapy

    Författare :Richard Lindgren; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Changes during female menopause include increased prevalence of vasomotor symptoms, vaginal symptoms, changes in sexlife and metabolic changes with increased risk of osteoporosis and cardiovascular disease. These changes are to some extent counteracted by estrogen replacement therapy. LÄS MER

  4. 4. Management of severe male infertility with special reference to IVF and ICSI

    Författare :Björn Rosenlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Until recently the treatment options for couples with severe male factor infertility have been restricted. With the advent of intracytoplasmic sperm injection (ICSI) it has now become possible to offer these couples effective treatment. LÄS MER

  5. 5. Assisted reproduction technology in men with ejaculatory dysfunction with special reference to spinal cord injury

    Författare :Claes Hultling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Men afflicted by spinal cord injury (SCI), myelomeningocele (MMC) and testicular cancer (TC) with retroperitoneal lymph-node dissection (RPLND) share the problem of infertility due mainly, but not exclusively, to neurologic impairment. This problem has historically been neglected, partly due to lack of effective treatment, partly due to lack of appreciation of the importance of sexual and procreational issues for rehabilitation outcomes and quality of life.
