Rapporten behandlar arbetsmiljön vid termisk ogräsbekämpning. Metoden innebär att ogräset hettas upp med hjälp av gaslågor. Både stora fordonsburna och mindre handdrivna används. Det som från arbetsmiljösynpunkt är speciellt med metoden är de risker som är förknippade med gasolanvändningen. De allvarligaste problemen med de aggregat som studerats har varit heta och oskyddade plåtar, heta avgaser o
In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environmental conditions are favourable throughout the year, so that parasites could benefit from a year-round transmission strategy. We analysed how different transm
Popular Abstract in Swedish Huvudtanken i svensk välfärdspolitik är att genom generella åtgärder skapa ett samhälle tillgängligt för alla medborgare. Det är därför viktigt att undvika segregering och särlösningar och i stället höja normalverksamhetens standard. Fritidshemmets mål och uppgifter är desamma för alla barn och kvaliteten i verksamheten ska vara så hög att alla barns behov tillgodoses. The main idea behind the Swedish welfare state is to create a society accessible to all citizens by using to general measures. It is, therefore, important to avoid segregation and special solutions, and instead increase the standard of normal activities. The objectives and tasks of day centres for school-age children are the same for all children and the quality of the operations should be of a st
The formation of micro-droplets due to a pulsative micro-jet (width of 40 mu m) is studied using the 3D Navier-Stokes equations for multi-phase flows using the Volume of Fluid (VOF) and Volume of Solid (VOS) models. The droplet formation is studied for different transient velocity conditions and mass rates. The numerical results show reasonable agreement with both analytical theory and experimenta
In this article we take the classic meaning of exemplum as a point of departure to show how examples are marked and used in oral discourse on 'others'. The empirical material is a transcribed focus group interview with Swedish students talking about a trip to Warsaw. Examples may be marked in explicit ways but also in implicit ways. Some examples seem recognizable by their allusive nature, others
A microfluidic device for particle washing was designed utilizing an acoustic standing wave field in a micro channel. Particles were focused in the center of the channel by the acoustic radiation force while the original carrier media was shifted sideways (orthogonal to the flow) at a number of consecutive wash fluid flow junctions along the main flow. Experiments were carried out in order to comp
The objective of this study was to describe environmental barriers and investigate the nature of accessibility problems in housing among single-living, very old people (N = 1,150) in urban regions in three European countries (Sweden, Germany, Latvia), in a one-year perspective. A specific feature of this study is the explicit conceptual differentiation between environmental barriers and accessibil
A new Key Environmental Performance Indicators (KEPIs) approach has been developed considering the perspective of a designer who may like to improve the environmental performance of the products but has limited resources and understanding of complex environmental issues. This approach empowers the designer with indicators like the area of PWB, the amount of precious metals etc which account for th
Using Low Energy Electron Diffraction (LEED) and Scanning Tunneling Microscopy (STM) we have investigated the structure of the GaP(111)B surface. We have previously studied the formation of Ga droplets on GaP(111)B above the maximum temperature for congruent evaporation. In the present work, we investigate the nanometer-sized pyramid-shaped crystallites that are found on the GaP(111)B surface and
Sweden's connections to and relationships with the European and wider world is a field of study attracting considerable scholarly attention. The essays here, from archaeologists and historians, offer a new perspective on early modern Sweden as deeply affected by the increasing internationality of the 16th-18th centuries. Set in the socio-political context of an expanding and changing kingdom, they
Emission trading schemes (ETS) have emerged as a popular climate policy measure and are increasingly advocated as policy instruments to support the transition to a green economy. Using complementary analytical methods, this research investigated the institutional developments and complexities of the New Zealand Emissions Trading Scheme (NZ ETS). It focuses on (1) institutional experience and admin
The cellular hallmarks of Parkinson's disease (PD) are the loss of nigral dopaminergic neurons and the formation of α-synuclein-enriched Lewy bodies and Lewy neurites in the remaining neurons. Based on the topographic distribution of Lewy bodies established after autopsy of brains from PD patients, Braak and coworkers hypothesized that Lewy pathology primes in the enteric nervous system and spread
