  1. 1. The diapause switch : Evolution of alternative developmental pathways in a butterfly

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Inger Marie Aalberg Haugen; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental plasticity; phenotypic plasticity; developmental switch; threshold trait; life-cycle regulation; direct development; Lepidoptera; zoologisk ekologi; Animal Ecology;

    Abstract : Diapause decision is a classic example of a threshold switch mechanism with cascading effects on morphology, behaviour and life-history traits. This thesis addresses the downstream effects of the insect diapause switch, with the main focus on pathway-specific regulation of life-history traits, using the speckled wood butterfly (Pararge aegeria) as a study species.

  4. 4. Organic electronic switch devices

    University dissertation from Linköping : Linköpings universitet

    Author : Fredrik Jakobsson; Linköpings universitet.; Linköpings universitet.; [2006]

    Abstract : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. READ MORE

  5. 5. Bariatric Surgery Outcomes after Gastric Bypass and Duodenal Switch

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Löfling Skogar; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; fat-free mass; resting metabolic rate; bariatric surgery; obesity; Roux-en-Y Gastric Bypass; Duodenal Switch; air-displacement plethysmography; Bod Pod; indirect calorimetry assessment; BAROS; quality of life; weight loss; diabetes; hypertension; dyslipidmia; depression; pain; antidepressants; opioids; complications; healthcare consumption; adverse events; Surgery; Kirurgi;

    Abstract : Obesity is associated with increased morbidity and mortality. A BMI >40 kg/m2 shortens life expectancy by about 10 years. The obesity related comorbidities diabetes, hypertension, dyslipidemia and sleep apnea contributes to the increased risk of cardiovascular events. There is also an increased risk of some forms of cancer (e. READ MORE
