1. 21. Methods for Capacity Allocation in Deregulated Railway Markets

   Författare :Abderrahman Ait Ali; Jonas Eliasson; Anders Peterson; Maria Börjesson; Yves Crozet; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway capacity; capacity allocation; train timetable; cost benefit analysis; deregulated market; spårkapacitet; kapacitetstilldelning; tågtidtabell; samhällsekonomisk analys; avreglerad marknad;

   Sammanfattning : Faced with increasing challenges, railways around Europe have recently undergone major reforms aiming to improve the efficiency and competitiveness of the railway sector. New market structures such as vertical separation, deregulation and open access can allow for reduced public expenditures, increased market competition, and more efficient railway systems. LÄS MER

   Sammanfattning : Due to the hydrophobic nature of integral membrane proteins (IMP) they give rise to several difficulties concerning handling and analysis, which is not the case for the most water soluble proteins. New analysis methods are needed, where the insolubility problems of the hydrophobic proteins due to aggregation and adhesion are tackled. LÄS MER

4. 23. Health Promotion Intervention in Mental Health Services

   Författare :Petra Svedberg; Institutionen för hälsovetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Nursing; Questionnaire; Medicine human and vertebrates ; Health promotion; Phenomenographic.; Mental health services;

   Sammanfattning : The aim of this thesis was to define and develop the concept of health promotion in mental health services as well as to develop a questionnaire to measure patients? subjective experiences of health promotion intervention in mental health services. The samples consisted of 12 patients in study I and 12 nurses in study II as well as 135 patients in mental health services in study III and IV. LÄS MER

5. 24. Provtagnings- och analysstrategi för lämplig mätosäkerhet

   Författare :Patrik von Heijne; Jenny Norrman; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Sammanfattning : Prior to the remediation of brownfields, extensive sampling and analysing isdone. The planned and reached measurement uncertainties are seldom asked forcontracting such types of investigations. Therefore they are usually not statednor discussed in the tenders. LÄS MER

7. 25. Structure-acoustic analysis; finite element modelling and reduction methods

   Författare :Peter Davidsson; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; low frequency range; building acoustics; lightweight structures; porous materials; modal reduction; substructuring; finite element analysis; structural acoustics; vibroacoustics; Structural dynamics;

   Sammanfattning : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. LÄS MER
