  1. 1. Parity Effects in Single Charge Tunneling

    Författare :Magnus Gisselfält; Chalmers University of Technology; []
    Nyckelord :mesoscopic; single charge tunneling; photon-assisted tunneling; shot noise; SET transistor; parity effect; Andreev tunneling; Coulomb blockade;

    Sammanfattning : The subject of this thesis is single charge tunneling effects, especially parity effects, as they are manifested in quantum mechanical tunneling through a metallic island small enough to cause single electrons to block tunneling of other electrons due to Coulomb interaction. When the island is superconducting the ground state energy depends on the parity of the number of electrons on the island: outside of the condensate there will always be at least one electron contributing to the energy for an odd number of electrons and this will have observable consequences.

  2. 2. Reproductive Factors and Breast Cancer - Parity, Breastfeeding and Genetic Predisposition in Relation to Risk and Prognosis

    Författare :Salma Butt; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subgroups; stage; survival; Breast cancer risk; parity; nulliparity; multiparity; breastfeeding; age at first birth; single nucleotide polymophisms;

    Sammanfattning : The aim of this thesis was to study reproductive factors and genetic polymorphisms in relation to breast cancer risk and survival. An important component of this was to investigate the risk of specific breast cancer subgroups. LÄS MER

  4. 4. Impact of pregnancies on ovarian cancer : Risk, prognosis and tumor biology

    Författare :Camilla Sköld; Ingrid Glimelius; Karin Stålberg; Anthoula Koliadi; Gunilla Enblad; Annika Idahl; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epithelial ovarian cancer; non-epithelial ovarian cancer; reproductive history; parity; risk factor; survival; progesterone receptor;

    Sammanfattning : Ovarian cancer is the most lethal gynecological malignancy. The etiology is complex and not fully understood, partly since ovarian cancer is not one distinct disease, but rather several histologically and clinically different subtypes. LÄS MER

  5. 5. Pregnancy in women with congenital heart disease

    Författare :Eva Furenäs; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :congenital heart disease; pregnancy; risk classification; parity; heart biomarker; NTproBNP; hs-cTNT;

    Sammanfattning : Abstract Background: The survival for children born with congenital heart disease (CHD) has increased and the majority reach adult age. Having a cardiac problem raise questions on the probability of successful pregnancies and predictors associated with unfavorable outcome. LÄS MER
