Cryptic pigmentation of prey is often thought to evolve in response to predator-mediated selection, but pigmentation traits can also be plastic, and change with respect to both abiotic and biotic environmental conditions. In such cases, identifying the presence of, and drivers of trait plasticity is useful for understanding the evolution of crypsis. Previous work suggests that cryptic pigmentation
Background: Quantitative magnetic resonance imaging (MRI), e.g. relaxation parameter mapping, may be sensitive to structural and compositional tissue changes, and could potentially be used to non-invasively detect and monitor early meniscus degeneration related to knee osteoarthritis. Objective: To investigate MR relaxation times as potential biomarkers for meniscus degeneration through comparison
Heterogena katalysatorer för användning i bränslecellssystem har undersökts baserat på aktiv fas och tillverkningsmetoder för granulat- och monolitkatalysatorer. Katalysatorerna tillverkades genom att använda θ – aluminiumoxid som bärare, dopad med lantan och cerium, där den aktiva fasen bestod av ädelmetall X och nickel i varierande halter. Analys gjordes genom att låta en blandning av vattenångaHeterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. Analy

Detta genom att undersöka hur andra aktörer inom branschen agerar i frågan och kartlägga modeller och verktyg för klimatberäkningar. Studien har utförts som en kombination av kvalitativa och kvantitativa forskningsmetoder, vilket kan liknas vid begreppet triaThe purpose of the study is to come up with recommendations and advice on how to calculate and present the climate impact from construction works. This will be implemented by examining how other actors within the construction industry is acting on the issue and examine models and tools for climate calculations. The study was conducted as a combination of qualitative and quantitative research meth
For historical reasons, Swedish railways use 15 kV/16? Hz overhead contact lines for train traction, while the most common standard worldwide is 25 kV/50-60 Hz. This leads to higher investment costs for railway conversions and expansions, and to greater energy losses in the distribution of electricity to the trains. Yet to get away from these drawbacks by investing in a 25 kV/50 Hz overhead contac
The response of concrete structures subjected to blast load can be studied numerically using commercial finite element programs. The complexity of reinforced concrete makes modeling and simulation of large structures time and computer power consuming. Consequently, The Swedish Defense Research Agency, FOI, has an interest in finding a fast and numerically efficient model to study this response to
Populariteten för släktforskning har vuxit under dom senaste åren. Detta beror framför allt på att det blivit avsevärt enklare genom internets framfart. Idag kan privat personer bedriva släktforskning hemifrån då man tidigare behövde hjälp från arkivister och professionella släktforskare. Då stora mängder släktdata har digitaliserats och lagts ut på nätet genom olika internationella företag och idAssociation for computer aided genealogy research of Sweden(DIS) is investigating the possibility of a nationwide genealogical database (RGD) of Sweden's historical population. The finished database should contain basic information about individuals' names, birth, marriage, death, and individuals' relationships such as father, mother, husband/wife and children. This will make up a kind
Virusinfektioner och Diabetes? Diabetes kännetecknas av konstant förhöjt blodsocker. Sjukdomen ökar i lavinartade former och beskrivs som en av det moderna samhällets stora epidemier. Diabetes förekommer vanligtvis i två huvudsakliga former, typ1 och typ 2. I typ I-diabetes (T1D), som framförallt drabbar barn och ungdomar, har de insulinproducerande beta-cellerna förstörts av kroppens immunförsvType 1 Diabetes (T1D) is an immune-mediated disease where the pancreatic beta cells are selectively destroyed by autoreactive CD8+ T cells. However, the triggering events that eventually leads to autoreactive CD8 T cells infiltrating the pancreatic islets and, subsequently, destroying them still needs to be unveiled. Genetic and epidemiological evidence points to a substantial influence of environ
Human telomerase reverse transcriptase (hTERT) is a critical factor in unlimited cell proliferation and immortalization, with numerous studies demonstrating that high expression of hTERT is a poor prognostic factor in various types of cancer. Ubiquitin-conjugating enzyme E2D 3 (UBE2D3) is a member of the E2 family, and participates in the ubiquitin proteasome pathway to regulate basic cellular act
AimPeak oxygen uptake (VO2peak) is closely related to total heart volume (THV) in healthy individuals. This study aimed to investigate 1) the association between VO2peak and THV in subjects with subclinical diastolic dysfunction, athletes, healthy controls, and patients with established heart failure with and without preserved ejection fraction (HFpEF, HFrEF), and 2) whether VO2peak/THV-index can
This study assesses the performance of buildings affected by climate change under future climate predictions for three time-periods until the end of the 21st century. Objects studied are residential multi-storey buildings, originally built before 1970 and retrofitted during the last decade. A total of four actual retrofit projects, as they were performed, in Denmark and Germany were assessed in th
När personer i ledande ställning inom ett bolag äger stora aktieposter i bolaget brukar det tolkas som en positiv signal på de finansiella marknaderna. Samtidigt är insiders förehavanden strikt reglerade och inom EU sker detta genom marknadsmissbruksförordningen (MAR). Denna uppsats fokuserar på det så kallade handelsförbudet i artikel 19.11 MAR. Handelsförbudet innebär att personer i ledande stälA management of a company with “skin in the game”, meaning insiders owning a considerable amount of stock, is seen as a positive signal on the markets. At the same time, insider dealings is a heavily regulated area, which in the EU is constituted by the Market Abuse Regulation (MAR). The focus of this essay is on the trade prohibition in article 19.11 MAR, which stipulates that persons discharging
