2. 1. Molecular Genetic Studies of the Blood Group ABO Locus in Man

   Author : Martin L Olsson; Avdelningen för hematologi och transfusionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chi sequence; recombination; population studies; blood group serology; erythrocyte; blood transfusion; sequencing; DNA; PCR; genomic; Blood group ABO; allele; Immunology; serology; transplantation; Immunologi; serologi; Clinical genetics; Klinisk genetik;

   Abstract : The ABO blood group system is undoubtedly the most important genetic and phenotypic marker in clinical transfusion medicine. The A and B determinants are immunodominant, terminally located carbohydrate residues of glycoconjugates on erythrocytes and other cell surfaces. READ MORE

4. 2. Optical Transmission Systems Based on Phase-Sensitive Amplifiers

   Author : Samuel L I Olsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical injection locking; fiber nonlinearities; optical fiber communication; fiber nonlinearity mitigation; four-wave mixing; fiber optic parametric amplification; low-noise amplification; phase-sensitive amplification; fibre optics;

   Abstract : The capacity and reach of today's long-haul fiber optical communication systems is limited by amplifier noise and fiber nonlinearities. Conventional, phase-insensitiveamplifiers (PIAs), have a quantum limited noise figure (NF) of 3 dB at high gain, meaning that with a shot-noise limited input signal the signal-to-noise ratio (SNR)is degraded by at least 3 dB.

5. 3. Towards Practical Implementation of Phase-Sensitive Amplifier Based Transmission Systems

   Author : Samuel L I Olsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-sensitive amplification; four-wave mixing; nonlinear optical signal processing; optical injection locking; fiber nonlinearities; fiber optic parametric amplification;

   Abstract : All commercially available optical amplifiers are so-called phase-insensitive amplifiers (PIAs) which degrade the signal-to-noise ratio (SNR) through the amplification process. This kind of amplifier has a quantum limited noise figure (NF) of 3 dB. READ MORE

6. 4. Surface reactions on mineral particles controlling the hydrolysis of glucose phosphates

   Author : Rickard Olsson; Per Persson; Reiner Giesler; Dean L. Hesterberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

   Abstract : Phosphorus (P) is an essential nutrient. A significant amount of soil P may be in the form of organophosphates. Due to the size of these compounds, hydrolysis is often required before P can be assimilated by organisms. Hydrolysis may be mediated by mineral surfaces, or catalyzed by extra cellular enzymes.

7. 5. Unraveling the Socio-Technical Tensions of Performance Measurement in Public Welfare Organizations

   Author : Annika Hasselblad; Leif Olsson; Katarina L Gidlund; Aron Larsson; Karin Danielsson; Mittuniversitetet; []
   Keywords : ;

   Abstract : In the name of efficiency, performance measurement has gained traction in public welfare organizations. The idea of performance measurement originates from views of all organizations rooted in scientific management notions that emerged during industrialization, as kinds of production units, according to an industrial logic.
