  3. 2. Delayed Sleep Phase Disorder : Prevalence, Diagnostic aspects, Associated factors and Treatment concepts

    Författare :Katarina Danielsson; Agneta Markström; Broman Jan-Erik; Markus Jansson-Fröjmark; Lars von Knorring; Pallesen Ståle; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; delayed sleep phase disorder; prevalence; diagnostic aspects; associated factors; light therapy and cognitive behavior therapy;

    Sammanfattning : Delayed sleep phase disorder (DSPD) is the most common circadian rhythm sleep disorder. Persons with DSPD have great difficulties falling asleep and waking up at conventional times. To diagnose DSPD this delayed sleep-wake rhythm should cause social impairment and distress for the individual. LÄS MER

  4. 3. Environmental Assessment of Materials, Components and Buildings Building Specific Considerations, Open-loop Recycling, Variations in Assessment Results and the Usage Phase of Buildings

    Författare :Mathias Borg; KTH; []
    Nyckelord :Life cycle assessment; Building materials and components; Buildings and constructions; Allocation; Result variation; Usage phase; Energy demand;

    Sammanfattning : The building sector is a major contributor to theenvironmental loads generated by the society. The recognitionof this fact by the sector and a general strive toward asustainable society have lead to afocus on different toolsthat can be used to enhance the environmental performance ofthe sector and the society.

  5. 4. Phase field modeling of flaw-induced hydride precipitation kinetics in metals

    Författare :Claudio F. Nigro; Christer Persson; Malmö högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydride; phase field theory; linear elastic fracture mechanics; finite element method; phase transformation; hydrogen embrittlement; finite volume method;

    Sammanfattning : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. LÄS MER

  7. 5. Implementation and use of finance information system: Results of a field study in Ugandan Universities

    Författare :David Kiwana; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Critical success factors; Developing Countries; Finance Information Systems; Implementation; Usage;

    Sammanfattning : Benefits arising from the use of finance information systems that include among others capability to offer improved timely and reliable accounts reports have been mentioned by many different scholars. The issue of successfully implementing and using the systems is however still a challenging problem especially in developing countries. LÄS MER
