Biological invasions offer fertile grounds for studying evolutionary ecology because species’ contact histories are uncharacteristically well-defined. As a result, invasions can be used to gain glimpses of the earliest micro-evolutionary responses of natural populations to new species’ interactions by studying changes in behaviour, physiology or morphology in space and time. Here, the known histor
Simultaneous OH-, fuel- planar laser induced fluorescence (PLIF) and particle image velocimetry (PIV)measurements were performed in turbulent low-swirl stratified premixed flames. The combined PIV/PLIF images revealed e.g. the fuel distribution, entrainment of ambient air, mixing with the air/fuel stream and the resulting stratification in the trailing edge of the flame. Flame-flow interaction was
The sphere detector is near-optimal in bit error rates (BER) performance for MIMO detection, but it suffers from the lower detection throughput. In this paper, we propose an improvement to the sub-optimal MIMO detection. The proposed detector can achieve a much higher detection throughput than the sphere detector, with a comparable complexity and a small degradation in BER performance at high sign
The aim of this sociology of law-orientated article is to analyse and describe legislative and regulatory processes concerning the task given to schools focusing on environment and sustainable development. We are describing the policy-making processes in this field from 1990 to 2011. The study involves key interviews and content analysis of national policy documents as well as legal sources, in or
This chapter does not deal with any practical aspects of light measurement, only with theoretical concepts. The following concepts are explained: energy fluence, energy fluence rate, photon fluence, photon fluence rate, radiance and mol, as well as the following superfluous or obsolete terms and synonyms: actinic flux, space irradiance, scalar irradiance, spherical irradiance, vectorial irradiance
We are good at discussing law statements of different epistemic status, and to describe logical relationships between different law statements. But contemporary discussion often suffers from a difficulty to formulate questions concerning laws of different ontological status. This paper presents a framework for distinguishing between properties and fake properties that seems to provide better tools
This paper describes trade-offs involved in designing a dual-band CMOS frontend for wireless local-area network (WLAN). Three 0.18μm CMOS frontends have been investigated, a single-band frontend at the 2.4 GHz ISM band, a single-band frontend at the 5 GHz U-NII band and a dual-band frontend. The study shows that employing a dual-band frontend yields satisfactory results, although some compromises
The chapter describes the evolution towards integrating mobility management offices into municipalities' existing organisational structure and activities. Experiences from six Swedish municipalities.
This paper discusses the concept of ‘precarious employment’ in relation to the Swedish shipbuilding industry in the 1960s and 1970s. In this setting, characterized by shortage of labour, a dual labour market structure emerged, where some workers were directly employed by the shipyards and others indirectly employed through intermediaries. The case differs from classical accounts of dual labour mar
