This paper presents a fully integrated downlink for low-cost remote antenna units in fiber-fed distributed multi-antenna systems. To reduce the cost of optical parts, an intermediate frequency(IF) signal is distributed over the fiber, and the circuit consists of an optical receiver, a single side-band frequency up-converting radio transmitter, and LO generation circuitry. The optical to electrical

In this thesis, I have focused on five main research areas: 1). A new type of imprinted polymer has been developed, namely the amide MIP. The amide functional monomers showed better hydrogen bonding capabilities in polar organic solvents and the resulting polymers exhibited good enantiomeric recognition properties in organic media. Furthermore, by using the amide monomers instead of the carboxyl m

The aim of this work was to study alterations in the matrix composition of human articular cartilage in different stages of osteoarthritis and to isolate and characterize one of the proteins that is altered in the osteoarthritic process. The metabolism of articular cartilage in different stages of osteoarthritis including early asymptomatic OA was monitored in a culture system of metabolically lab

Designed to meet the diverse needs of therapists, this book presents a new approach to rehabilitation that integrates ergonomics concepts to address the wide range of problems commonly encountered by professionals. The first section addresses general concepts such as anthropometry and tissue mechanics. The next section explores whole body biomechanics, demonstrating the ergonomic effects of physio

ESA's Gaia mission will observe huge numbers of binaries with a largerange of periods. The present contribution presents results from somelarge-scale simulations, based on a simplified population synthesismodel Galaxy consisting mostly of binaries. The results are 'typical'solution-numbers and -types, for stellar samples at different distancesfrom the sun. As in previous studies, there are marked

The chapter emphasizes the historical position of the layman in the Church of Sweden as an independent complement to women and clergymen. Spiritual letters, funeral sermons, and fictional material are used as sources. During the nineteenth century the Christian layman was professionalised or specialised in a way that did marginalize him as the layman as such.

Attracting membership while stifling freeriding and heterogeneous preferences among potential members is critical for trade union success. Women are generally seen as less inclined to join trade unions, particularly at the onset of the labor movement. We highlight a previously neglected explanation for this: the importance of risk and gender differences in assessment hereof. We study matched emplo
