1. 6. Conjoint analysis as a tool for communication and corporate environmental decision-making

   Författare :Stina Alriksson; Tomas Öberg; Marianne Lindström; Högskolan i Kalmar; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjoint analysis; PLS; Cluster analysis; Communication; Environmental; Decision-making; Environmental engineering; Miljöteknik; Miljövetenskap; Environmental Science;

   Sammanfattning : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.

3. 7. Consuming and Communicating Fruit and Vegetables : A Nation-Wide Food Survey and Analysis of Blogs among Swedish Adults

   Författare :Anna-Mari Simunaniemi; Margaretha Nydahl; Agneta Andersson; Helena Sandberg; Liisa Valsta; Uppsala universitet; []
   Nyckelord :fruit and vegetables; 24-h recall; food frequency questionnaire; discourse analysis; cluster analysis; communication; blogs; Culinary Arts and Meal Science; Måltidskunskap; Kostvetenskap; Food; Nutrition and Dietetics;

   Sammanfattning : The aim of this thesis was to investigate fruit and vegetable (F&V) consumption among Swedish adults and to use F&V-related perceptions for audience segmentation. Further, the aim was to identify motives and approaches of F&V bloggers, as well as to analyze F&V-related online discourses. LÄS MER

4. 8. cancer subtype identification using cluster analysis on high-dimensional omics data

   Författare :Linda Vidman; Patrik Rydén; Jun Yu; Erik Kristiansson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cluster analysis; cancer; classification;

   Sammanfattning : Identification and prediction of cancer subtypes are important parts in the development towards personalized medicine. By tailoring treatments, it is possible to decrease unnecessary suffering and reduce costs. Since the introduction of next generation sequencing techniques, the amount of data available for medical research has increased rapidly. LÄS MER

5. 9. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

   Författare :Mats Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

   Sammanfattning : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. LÄS MER
