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
OBJECTIVES: To investigate the mechanisms of platelet kinetics in the SMART study that demonstrated excess mortality with CD4 guided episodic antiretroviral therapy (ART) (drug conservation [DC]) compared to continuous treatment (viral suppression [VS]). Follow up analyses of stored plasma samples demonstrated increased activation of both inflammatory and coagulation pathways after stopping ART.
Several psychiatric disorders, including major depressive disorder (MDD), are associated with increased blood markers of oxidative stress. The relevance of this to the oxidation-sensitive hippocampus (HC) is unknown. We investigated the relationship between peripheral oxidative stress markers and HC volume in unmedicated individuals with MDD (n=16) and healthy controls (n=19). To conserve power, o
We report on the characterization of the new I1011 beamline at the MAX-II storage ring, in the MAX-lab synchrotron radiation laboratory and give examples of first results. This beamline is using an Elliptically Polarizing Undulator source, producing soft x-rays of a variable polarization state. It delivers high flux and high brightness circularly polarized x-rays in the energy range 0.2 to 1.7 keV
This study is a contribution to the empirical underpinning of the Common European Framework of Reference for Languages (CEFR), and it aims to identify linguistic correlates to the proficiency levels defined by the CEFR. The study was conducted in a Swedish school setting, focusing on English, French and Italian, and examined the relationship between CEFR levels (A1-C2) assigned by experienced rate
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
When a country liberalizes trade through lowering taxes on imports, it stands before a number of challenges. Recovering lost trade tax revenue is one of them. Cape Verde is one of the countries that are currently negotiating an Economic Partnership Agreement with the EU and studies predict that the tariff reductions resulting from the agreement may have a severe impact on Cape Verde’s government r
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
IntroductionPost-operative infections obtained from open-wound surgeries constitute an unnecessary load on both healthcare and affected patients. It is well established that increased air cleanliness reduces the number of post-operative infections. Therefore, the ventilation system is important in order to reduce the number of infectious particles in the air during surgery. Ventilation with high a
Weather conditions affect animals in many different ways. Variation in temperature, rainfall, wind, and other environmental variables can have an impact at a range of temporal and spatial scales and at every level from individual behavior to species distributions. The interactions between these variables may be particularly important but are often overlooked. Hence, understanding how animals respo
Massive bird migration across continents and seas is one of the most spectacular phenomena in nature, involving billions of birds annually. In the autumn, most birds on migration are juveniles migrating for the first time while adults are repeating their migrations. Migration syndrome in individual bird migrants involves multiple behavioural, morphological and physiological adaptations, and migrat
The objectives of this study are to assess the perception of slipperiness, thermal comfort, and wearability of footwear used on icy surfaces, and the anti-slip effect of materials spread on ice using outdoor walking trials. Twenty-five subjects wore four types of footwear walking on five different icy surfaces. Five-point rating scale was used recording wearer's perception. The results showed that
