Traits that increase mating success in males may come at a cost, such as an increased risk of predation. However, predator-mediated selection is challenging to document in natural populations, hampering our understanding of the trade-offs between sexual selection and predation. Here we report on a study of predator-mediated natural selection on wing traits in the damselfly Calopteryx splendens, th

Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in

Background. Although muscle wasting may lead to decreased ammonia detoxification in cirrhosis, the potential role of lean mass depletion in hepatic encephalopathy (HE) has not been explored. Anemia, hormonal abnormalities, and psychological distress may contribute to cognitive dysfunction, but data on their potential relation to HE are limited. Methods. Data on 108 cirrhotic liver transplant candi

Asthma-like symptoms, methacholine hyperresponsiveness, and use of asthma medication are prevalent in elite cross-country skiers. We quantitated mucosal inflammatory cell infiltration and tenascin expression in the subepithelial basement membrane in endobronchial biopsy specimens of the proximal airways from 40 elite, competitive skiers (mean: 17.5; range: 16 to 20 yr) without a diagnosis of asthm

High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work, the high-spin structure of Er-156,Er-157,Er-158 has been studied using the Gammasphere spectrometer. The subject of triaxi

Hierarchical manners and taxing work complicate the picture of the restaurant industry, a sector in great need of personnel. There is little scientific research on daily work in restaurants. Through interviews and observations in restaurant kitchens, three head chef practices were detected: “Master the materiality” is a stipulation for leading kitchens, but does not imply leadership aspirations; “

En majoritet av de nordliga torvmarkerna utvecklades under holocen som ett resultat av en positiv massbalans mellan nettoprimärproduktion och heterotrofa nedbrytningshastigheter. Sedan dess har de lagrat stora mängder kol i terrestra ekosystem. En betydande del av dessa områden sammanfaller också med regioner med underliggande permafrost och uppvisar olika ackumulationsmönster av torv. Således, föThe majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. A significant proportion of these areas also coincides with areas underlain with permafrost and shows a diverse range of peat

In this study, a mathematical model was developed to simulate the jet and plume behavior in order to determine the optimum discharge conditions for different scenarios. The model was divided into two sub-models, describing respectively the near and intermediate field properties of the discharge for different inclinations and bottom slope. The lateral spreading and electrical conductivity was also

Objective. To compare how costs relate to disability, disease activity, and health-related quality of life (HRQOL) in rheumatoid arthritis (RA). Methods. Antitumor necrosis factor (anti-TNF)-treated patients with RA in southern Sweden (n = 2341) were monitored 2005-2010. Health Assessment Questionnaire (HAQ), 28-joint Disease Activity Score (DAS28), and EQ-5D scores were linked to register-derived

The risk for drinking water scarcity does not only concern developing countries and arid places. In its 2023 report, the Intergovernmental Panel on Climate Change has identified water scarcity as one of Europe’s key risks out of five in the foreseeable future. Sweden experiences water shortages more and more frequently during summer, and the need to protect groundwater resources is imperative. In

There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. The classifier used hyperspectral images in infrared of four

VETENSKAP OCH BEPRÖVAD ERFARENHET VID SBU | 1 VETENSKAP OCH BEPRÖVAD ERFARENHET MILJÖ Vetenskap och beprövad erfarenhet är ett minst sagt viktigt begrepp. Via olika lagar och förordningar påverkar det våra myndigheter. Det påver- kar oss som yrkesutövare och som medborgare. Samtidigt är det något oklart vad som avses. Vad menar vi med vetenskap? Vems eller vilkas beprövade erfarenhet talar vi om o

The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. Further, the wavefront of the zeroth order diffraction spot of M

Background In many European countries, medicines promotion is governed by voluntary codes of practice administered by the pharmaceutical industry under its own system of self-regulation. Involvement of industry organizations in policing promotion has been proposed to deter illicit conduct, but few detailed studies on self-regulation have been carried out to date. The objective of this study was to

Människan och hampan (Cannabis sativa) har en gemensam historia som går långt bak i tiden, denna historia är dock omgiven av kontroverser. Idag är Cannabis mest känt för sina psykoaktiva egenskaper och narkotika klassificering i många länder, men hampa har historiskt sett främst odlats för fiberproduktion. Denna studie undersöker historisk hampaodling i Europa och är baserad på redan publicerade dHumans and hemp (Cannabis sativa) have an ancient relationship, dating back to the beginning of recorded history. Nevertheless, controversy surrounds the antiquity of the plant. Today Cannabis is probably most famous for its psychoactive properties and illicit status in numerous countries, however hemp has primarily been cultivated as a fibre crop in the past. This study examines the European hist
