1. On Finding Spectrum Opportunities in Cognitive Radios : Spectrum Sensing and Geo-locations Database
Sammanfattning : The spectacular growth in wireless services imposes scarcity in term of the available radio spectrum. A solution to overcome this scarcity is to adopt what so called cognitive radio based on dynamic spectrum access. LÄS MER
2. Enterobacteriaceae Producing Extended-Spectrum Beta-Lactamases : Aspects of Detection, Epidemiology and Control
Sammanfattning : Enterobacteriaceae belong to the normal enteric flora in humans and may cause infections. Escherichia coli is the leading urinary tract pathogen with septicaemic potential, whereas Klebsiella pneumoniae causes opportunistic infections and often outbreaks in hospital settings. LÄS MER
3. Methods and techniques for precise and accurate in-duct aero-acoustic measurements : Application to the area expansion
Sammanfattning : During the design and commissioning of combustion equipment, combustion associated instabilities are commonly encountered. These thermo-acoustic instabilities can cause undesirable noise, vibrations, local thermal and mechanical stresses in the combustor and are prominent in lean combustion. LÄS MER
4. Apoptosis of Peripheral Blood Leukocytes in Systemic Lupus Erythematosus: Studies on Serum Induction and Complement-Dependent Clearance Mechanisms
Sammanfattning : Systemic lupus erythematosus (SLE) is an autoimmune disease involving many organ systems. The cause is not known, but a complex combination of environmental and genetic factors seems to be involved. LÄS MER
5. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression
Sammanfattning : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.
