   Författare :Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. LÄS MER

3. 17. Malignant glioma : experimental studies with an estrogen-linked cytostatic

   Författare :Eva von Schoultz; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malignant glioma; meningioma; glioma cells; sex steroids; estramustine; nor-nitrogen mustard; estramustine- binding protein; DNA damage; cell membrane;

   Sammanfattning : Malignant gliomas are the most common primary brain tumors in adults. Patients with these highly malignant tumors have an extremely poor prognosis. The situation with a highly proliferative tumor in a non-proliferating tissue should favor cytostatic treatment but so far the role of conventional chemotherapy has been adjunctive. LÄS MER

4. 18. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

   Författare :Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []

   Sammanfattning : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. LÄS MER

5. 19. Multimodal phenotyping of synaptic damage in Alzheimer’s disease : translational perspective with focus on quantitative EEG

   Författare :Una Smailovic; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the most common form of dementia. Accumulation of AD-associated pathology in the brain may begin a decade or more before the appearance of the first symptoms of the disease. LÄS MER

7. 20. Multiple Sclerosis: Studies of the Interferon system and search for infectious agents

   Författare :My Bergkvist; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; Axon and myelin damage; IgG; Virus; Interferon; Multiple Sclerosis; Genetic linkage;

   Sammanfattning : Multiple sclerosis (MS) is a chronic disease of the central nervous system, characterized by focal inflammatory lesions with demyelination and axonal loss. It is believed that MS is an immune-mediated disorder with both genetic and environmental contributions to the pathogenesis. LÄS MER
