  2. 1. Studies in Glacier Mass Balance : Measurement and its errors

    Author : Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

    Abstract : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. READ MORE

  4. 2. Partial methane oxidation from electronic structure calculations

    Author : Adam Arvidsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ZSM-5 zeolite; density functional theory; microkinetic modelling; Mo6S8 cluster; partial methane oxidation;

    Abstract : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.

  6. 4. Modelling late toxicity in hypofractionated radiation therapy

    Author : Niclas Pettersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypofractionation; normal tissue complication probability; modelling; linear-quadratic model; fractionation sensitivity; late toxicity; radiation-induced rib fracture; genitourinary toxicity; stereotactic body radiation therapy; high-dose-rate brachytherapy; multimodality radiation therapy; patient-reported outcomes; prostate cancer; nsclc;

    Abstract : In hypofractionated radiation therapy (RT), the treatment is delivered by few fractions with high doses per fraction. This is in contrast to conventionally fractionated RT where the total dose is delivered in many fractions with low doses per fraction. READ MORE

  7. 5. Understanding West African Monsoon Variability : Insights from Paleoclimate Modelling of Past Warm Climates

    Author : Ellen Berntell; Qiong Zhang; Alessandra Giannini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; West African Monsoon; Monsoon Variability; Paleoclimate; Climate modelling; naturgeografi; Physical Geography;

    Abstract : The Sahel, a water-vulnerable region in West Africa, relies heavily on rainfed agriculture. The region experienced pronounced droughts during the 20th Century, emphasising the socio-economic importance of understanding the drivers of the rainfall variability. READ MORE
