  2. 1. Endocrine Disruption in Amphibians : Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System

    Author : Irina Gyllenhammar; Cecilia Berg; Ingvar Brandt; Lena Holm; Joakim Larsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Test system; Xenopus tropicalis; Rana temporaria; sex ratio; sex differentiation; fertility; aromatase; ovary; testis; oviduct; Biology; Biologi;

    Abstract : Amphibian populations are declining world-wide and one of the suggested reasons is environmental pollutants. Studies of long-term effects on the reproductive system in frogs following larval exposure to environmental pollutants are scarce. It is therefore important to develop methods to study developmental reproductive toxicity in amphibians. READ MORE

  4. 2. Endocrine disruption in fish : Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome

    Author : Tove Porseryd; Inger Porsch Hällström; Ioanna Katsiadaki; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 17α-ethinylestradiol; endocrine disrupting chemical; fish; behavior; fertility; transcriptome; RNA sequencing; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. READ MORE

  5. 3. Disruption Mitigation in Tokamaks with Massive Material Injection

    Author : Oskar Vallhagen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; shattered pellet injection; fusion plasma; disruption mitigation; runaway electron;

    Abstract : The sudden loss of confinement of the energy content of fusion plasmas in off-normal events, called disruptions, is among the most severe threats to the future of fusion energy based on the tokamak design. An efficient disruption mitigation system will therefore be of utmost importance for future large, high-current devices such as ITER. READ MORE

  6. 4. Exposure to Bisphenol A (BPA) and Metabolic Disruption

    Author : Linda Dunder; Monica Lind; Margareta Halin Lejonklou; Lars Lind; Anna-Maria Andersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bisphenol A BPA ; Endocrine disrupting chemicals EDCs ; Developmental exposure; Metabolic disruption; Adipose tissue; Fatty acids; Insulin secretion; Experimental rat study; Epidemiology; Medicinsk vetenskap; Medical Science;

    Abstract : Metbolic disorders such as obesity, type 2 diabetes, liver lipid disorders and metabolic syndrome are increasing rapidly and have largely been attributed to genetic background and changes in diet, exercise and aging. However, there is now considerable evidence showing that other environmental factors, including environmental chemicals, may contribute to the rapid increase in the incidence of these metabolic diseases.

  7. 5. Recovery actions in freight transport through real-time disruption management

    Author : Per Wide; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; freight transport; transport system; operational planning; proactive recovery actions; Disruption management; real-time information;

    Abstract : This thesis focuses on the management of disruption in freight transport. The management of disruption is of importance to achieve planned efficiency in the transport system by mitigating or avoiding the impacts of disruptions, such as late arrivals of deliveries. READ MORE
