1. 36. Phenomenology of Diffractive Higgs Production and Large Extra Dimensions

   Författare :Malin Sjödahl; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ADD; black holes; gravitational scattering; quantum field theory; Elementary particle physics; LHC; cosmic rays; Kosmisk strålning; högenergi; High energy interactions; kvantfältteori; Elementarpartikelfysik; Higgs; large extra dimensions; Diffractive;

   Sammanfattning : This thesis is based on phenomenological predictions for high energy particle collisions from two different theoretical models. The first two papers deal with uncertainties in exclusive reactions of type proton + proton -> proton + proton + Higgs. LÄS MER

3. 37. Lubricant rheology in refrigeration systems and magnetic storage devices

   Författare :Ulf Jonsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : This thesis comprises three papers concerning lubricant rheology in two different applications. The first two papers concern refrigeration systems and the importance of lubricant rheology in elastohydrodynamic lubrication in refrigerating compressors. LÄS MER

4. 38. Falls, perceived fall risk and activity curtailment among older people receiving home-help service

   Författare :Irene Vikman; Birgitta Lindmark; Luleå tekniska universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Sjukgymnastik; Centre - eHealth Innovation Centre EIC ; Centrumbildning - Centrum för Innovation och eHälsa EIC ;

   Sammanfattning : Falls and fall-related concern and fear of falling are not well understood when it comes to old people receiving home-help services, a transitional population in-between those living independently in the community and those living in residential care facilities. The psychological distress attributable to the perceived risk of falling among this population needs further exploration, which is also the case regarding possible ways to increase their feeling of security.

5. 39. Identification and promotion of attitudes related to pro-environmental travel behaviour

   Författare :Maria Johansson; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; travel behaviour; traffic restrictions; pro-environmental attitudes; politicians; computerised gaming simulation environmental knowledge; civil servants; children; adolescents; adults; Miljöteknik; kontroll av utsläpp; Road transport technology; Vägtransportteknik; Psychology; Psykologi;

   Sammanfattning : A reduction of the negative environmental impact caused by urban traffic will to a considerable extent depend on behavioural change. Assuming that attitudes partly guide behaviour, the general aim of the thesis was to increase the understanding of the underlying attitudes of daily travel behaviour and how attitudes related to pro-environmental choice of transport can be promoted.

7. 40. Two Essays on Relative Consumption

   Författare :Fredrik W. Andersson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; relative consumption; marginal degree of positionality; choice experiments; questionnaire-experimental methods;

   Sammanfattning : First paper: Consumption Theory with Reference Dependent Utility: Its Impact on Marginal Propensity to Consume This paper presents a closed form consumption function for an individual when he derives utility from his own previous and current consumption and from the previous consumption of his relevant others. I show that the individual's marginal propensity to consume (MPC) is smaller than the MPC under the permanent income hypothesis. LÄS MER
