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

Macroinvertebrates and fish in the contaminated river are faced with a higher risk to suffer from exposure to Hg than humans eating contaminated fish and bacteria living in the groundwater. The river sediment is the most hazardous source for the macroinvertebrates, and macroinvertebrates make up the highest risk for fish. The distribution of body concentrations of Hg in fish in the mining areas of

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

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

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

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

The aim of this qualitative study was to investigate the social identity of students at upper secondary school for physically disabled students. The youths I drew my attention to suffered from severe physical disabilities and therefore received specially adapted education in small classes, but integrated at an ordinary upper secondary school. By "social identity" I mean how the students

Popular Abstract in Swedish Turismindustrin är numera en av världens absolut största industrier. Den är av central betydelse för ekonomisk utveckling och arbetstillfällen i ett stort antal länder. Det finns dock en baksida: turism leder ofta till exploatering av miljön, och bidrar i många fall till sociala och kulturella problem. Dagens turismindustri är inte förenlig med hållbar utveckling och deTourism has become a leading industry in the world and continues to grow rapidly, contributing essentially to economic growth and employment in many countries. Tourism as it looks today poses serious threats to the environment and considerable social and cultural challenges. The problem addressed by this research lies in the weakness of current concepts and practices in pursuit of sustainable tour

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

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
