    Sammanfattning : It is evident that human activity has an important impact on climate. Constantly increasing energy demand is one of the biggest causes of climate change. The fifth assessment report of the Inter-governmental panel on climate change states that decarbonisation of electricity generation is a key component of climate change mitigation. LÄS MER

  2. 2. New evidence on germ-cell testicular cancer aetiology

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Epidemiology and Biostatistics

    Författare :Lorenzo Richiardi; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Testicular neoplasm; Seminomas; Nonseminomas; Case-control study; Risk factors; Perinatal characteristics; Body size; Subfertility; Occurrence.;

    Sammanfattning : Testicular cancer has been increasing in incidence for at least 50 years in many populations, but its etiology remains elusive. We investigated several prenatal and postnatal factors in association with germ-cell testicular cancer risk. Moreover, we evaluated recent trends in testicular cancer incidence in Northern European countries. LÄS MER

  3. 3. Risk and prognosis of breast cancer among women at high risk of the disease

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Epidemiology and Biostatistics

    Författare :Mikael Hartman; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; breast cancer; bilateral; familial; incidence; prognosis; age; latency; calendar period; adjuvant therapy;

    Sammanfattning : The overall objectives of this thesis were to increase our understanding of the risk and prognosis of breast cancer using the high risk groups of women with bilateral and familial breast cancer. Data from the Swedish Cancer Register, the Multi-Generation Register and the Cause of Death register was used in Paper I-III to identify women with bilateral cancer and study risk and prognosis of the disease.

  4. 4. Clinical and Epidemiological Studies of Wegener´s Granulomatosis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ann Knight; Uppsala universitet.; [2007]
    Nyckelord :Medicine; Wegener´s granulomatosis; incidence; time-trends; ANCA; familial aggregation; cancer risks; bladder cancer; cyclophosphamide; Medicin;

    Sammanfattning : Wegener´s granulomatosis (WG) is an unusual, serious, systemic vasculitis with specific clinical findings. The studies in this thesis aim at broadening our understanding of the aetiology and outcome of WG.Patients with WG were identified in the In-patient Register 1975-2001. LÄS MER

  5. 5. Ontogenetic bottlenecks effects on intraguild predation systems and ecosystem efficiency

    Detta är en avhandling från Umeå : Umeå University

    Författare :Birte Reichstein; Umeå universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed interactions; cannibalism; life-history omnivory; ontogenetic niche shift; biomass overcompensation; biomass production; ontogenetic asymmetry; indirect effects; biology; biologi; zooekologi; Animal Ecology;

    Sammanfattning : Size-dependent differences between individuals in size-structured organisms have fundamental effect on population and community dynamics. Intraguild predation (IGP) is one specifically interesting constellation that often arises when two size-structured populations interact. LÄS MER
