Generation of 15 monoclonal antibodies (MAbs) allowed construction of epitope maps and specific two-site immunofluorometric assays for free prostate-specific antigen (PSA) and PSA complexed with alpha 1-antichymotrypsin (ACT). Close correlation of PSA concentrations obtained with the use of different assays of free PSA suggested extensive similarity in immunodetection of free PSA in serum. Assays

The electric power system plays a central role in the transition to a sustainable energy system: Electric power based on renwable sources permits an increase in electricity consumption to eliminate fossil fuels. This brings large challenges to the electric power system in terms of adaptation to the variable production from wind power and solar electricity. These electricity sources are grid connec

Popular Abstract in Swedish Den rykande startpistolen eller Konsten att ta tid på en flygande elektron Flygande elektroner kan berätta mycket om hur världen sitter ihop. Elektroner som lämnar ytan av något material avslöjar både vilka atomer som finns i materialet och hur de kemiska bindingarna ser ut. Allt detta är nödvändigt att förstå när man vill utveckla nya material – till exempel för kretTime-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution. However, the advent of angle-resolved TOF spectrometers for electron energy analysis cha

Class II ribonucleotide reductases (RNR) catalyze the formation of an essential thiyl radical by homolytic cleavage of the Co-C bond in their adenosylcobalamin (AdoCbl) cofactor. Several mechanisms for the dramatic acceleration of Co-C bond cleavage in AdoCbl-dependent enzymes have been advanced, but no consensus yet exists. We present the structure of the class II RNR from Thermo toga maritima in

The European Spallation Source (ESS) is the European common effort in designing and building a next generation large-scale user facility for studies of the structure and dynamics of materials. The proposed schematic layout of the ESS facility is based on a linear driver (linac) directing the proton beam (5 MW of 2.5 GeV) of 2.8 ms long pulses with a 20 Hz on a tungsten target where neutrons are pr

Sammanfattning Under 1960-talet kunde vetenskapsmän konstatera att en generell uppvärmning av atmosfären resulterade i klimatförändringar. En av källorna till den globala uppvärmningen var och är fortfarande den höga koncentrationen av växthusgaser i atmosfären som uppstår genom mänsklig aktivitet vid förbränning av fossila bränslen. Trots den vetskapen dröjde det en bit in på 2000-talet innan kliSummary In the 1960’s scientists discovered that general heating of the atmosphere or global warming results in climate change. One of the reasons behind global warming is the high concentration of green house gases in the atmosphere, which is a bi-product of fossil fuel combustion caused by human activity. Climate change did not become a European Union priority before the 21st century when the c

The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. The strain pulse gives rise to coherent longitudinal, acoustic phonon

Enzymes that require a redox-active amino acid for catalysis or function have emerged as a distinct class of proteins. For the tyrosine-based radical enzymes, we show that the spin-density distribution in the radical follows an odd alternate pattern that is invariant to within 10% across the class. General properties of the radical enzymes are summarized from which we conclude that their essential

This study presents a novel approach using Gaussian process model predictive control (MPC) to stabilize the output voltage of a polymer electrolyte fuel cell (PEFC) by regulating hydrogen and airflow rates. Two Gaussian process models capture PEFC dynamics, accounting for constraints like hydrogen pressure and input change rates to reduce predictive control errors. The performance of the physical

Off-grid solar products play an essential role in increasing and improving rural energy access, thereby reducing poverty and mitigating climate change. Experiencing fast market growth in Central and Southern Asia and Sub-Saharan Africa, off-grid solar products will represent 50% of the newly established electricity connections in the world between 2017 and 2030. Despite such benefits and market su

A comprehensive dynamic control oriented model of a polymer electrolyte fuel cell (PEFC) is developed, considering the mixed effects of temperature, gas flow and capacitance. The fractional relationship between the dynamic output voltage and the capacitance, which escaped the attention in most previous studies is also addressed. Moreover, based on the developed PEFC model, a proportional integral
