11. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia
Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER
12. Considering external costs : Their influence on technical measures in energy systems
Sammanfattning : It is well known that conversion of energy gives rise to several environmental problems. The impact on the environment and human health can involve substantial indirect costs for society. These indirect costs are also known as external costs, since the market often does not consider them. LÄS MER
13. Cellular immune responses in allogeneic and xenogeneic transplantation models
Sammanfattning : The introduction of immunosuppressive agents and improvements in surgical techniques and ancillary care has made allotransplantation a routine procedure. However, improvements in short-term graft survival rates have not been accompanied by a similar improvement in long-term outcome due to the process of therapy-resistant chronic allograft rejection.

14. New aspects on timing and graft morbidity in anterior cruciate ligament reconstruction
Sammanfattning : The aim of this thesis was to investigate the effect of different surgical techniques on knee function and outcomes after an anterior cruciate ligament (ACL) reconstruction (ACLR). In Study I, 70 patients with a Tegner level of six or more were assessed after randomisation between acute ACLR (within 8 days after the injury) and delayed ACLR (after normalised range of motion [ROM] 6–10 weeks after the injury) using a four-strand semitendinosus tendon graft.

15. Exploring the Effects of ICT on Environmental Sustainability: From Life Cycle Assessment to Complex Systems Modeling
Sammanfattning : The production and consumption of information and communication technology (ICT) products and services continue to grow worldwide. This trend is accompanied by a corresponding increase in electricity use by ICT, as well as direct environmental impacts of the technology. Yet a more complicated picture of ICT’s effects is emerging. LÄS MER
