Background: The St Gallen surrogate molecular subtype definitions classify the oestrogen (ER) positive breast cancer into the luminal A and luminal B subtypes according to proliferation rate and/or expression of human epidermal growth factor receptor 2 (HER2) with differences in prognosis and chemo-responsiveness. Primary tumours and lymph node metastases might represent different malignant clones
The MHC (Major Histocompatibility Complex) plays an important role in the immune system of vertebrates. MHC genes are extremely polymorphic and this variation is considered to be maintained by selection from pathogens. We investigate whether MHC diversity (number of different alleles per individual) affects the survival and recruitment of nestling house sparrows. We hypothesize that individuals wi
The dielectric procperties of MSWI bottom ash as a function of volumetric water content (VWC) are reported in this paper. The objective was to aid the development of microwave based non-invasive emission monitoring and control system for various bottom ash applications. The dielectric measurements were made, on a 1.5-year-old bottom ash, with an electrical network analyzer in microwave range (300
Interactions between iron (Fe) and arsenic (As) play a vital role in aquatic and terrestrial ecosystems influencing the reactivity and transport of arsenic. A key aspect is the effect of natural organic matter (NOM) on these interactions, and previous investigations have reported the existence of ternary As-Fe-NOM species. In this study, the reactivity of Fe, from a boreal stream water, towards As
Water distribution and availability in the Jordan region were studied. Self-sufficiency in water availability within the region is determined by the minimum amount of water used per person that is renewable. The objectives of the study were to identify the causes of water shortages and alternative use of water to prolong future supplies. According to our analysis, Israel and Jordan will overutilis
The fate of phosphate in the environment is governed by reactions at particle surfaces. These adsorption and desorption reactions display biphasic kinetics involving an initial rapid reaction followed by a substantially slower one extending over long time periods. In this study we have investigated the molecular mechanisms of desorption kinetics of phosphate from ferrihydrite and goethite nanopart
Seeds of clover and lucerne were sown in equal proportions in mixtures at high densities. Thinning started earlier in clover but in both species, after thinning commenced, it proceeded at the same rate. Both species underwent collective self-thinning in accordance with the -3/2 power law but although the slopes for the species were the same the intercepts differed strongly. Plants of lucerne of a
The influence of environmental policy has been known to move beyond the country or regional contexts in which they have been implemented. Examples in literature include the “California effect” and the “Brussels effect”, showing how the policies adopted in the EU and California influence other jurisdictions. In this paper we study the following: To what extent are companies operating in the United
Plesiosaurs are an iconic group of Mesozoic marine reptiles with an evolutionary history spanning over 140 million years (Ma).1 Their skeletal remains have been discovered worldwide; however, accompanying fossilized soft tissues are exceptionally rare.2 Here, we report a virtually complete plesiosaur from the Lower Jurassic (∼183 Ma)3 Posidonia Shale of Germany that preserves skin traces from arou
Introduction Emerging research indicates that integrated treatment of co-occurring post-traumatic stress disorder (PTSD) and substance use disorder can be effective among adolescents and young people. However, various barriers exist to young people accessing evidence-based treatments. Telehealth offers an opportunity to address these barriers and provide a scalable and accessible alternative to in

Vägar slits konstant och kräver konstant förbättringar och ombyggnationer. För att möjliggöra detta krävs personer som befinner sig ute på vägarna. Tekniken har gått framåt inom området trafiksäkerhet men skulle behöva förbättras ytterligare om vägarbetare ska vara säkra på sin arbetsplats. Även trafiken har förändrats över åren. Idag finns fler fordon på vägarna än aldrig förr. Bilarna är säkrareRoads are constantly worn down and demands improvements and reconstructions. To make this possible there has to be road workers on the road. Road safety has been improved along the years but can still be improved more. Today there are more vehicles on the road than ever before. The cars are more safe and therefore is encouraging to higher speeds as they are driven together with all safety features
Climate change is a global threat to human and animals’ well-being on Earth. The threat of climate change has been known for over 30 years and it is now a fact that humans are the main contributing factor to it. Despite this, in 2022 it is no longer an abstract phenomenon, but our reality. One of the reasons why so little has been done to save the environment is people’s lack of or insufficient kn
A fundamental precept of geochemistry is that arsenate coordinates at mineral surfaces in a predominately bridging-bidentate fashion. We show that this is incorrect for the model system, arsenate adsorbed at the surface of goethite (alpha-FeOOH), using a combination of XRD, EXAFS, and IR spectroscopic results. We report the crystal structure of pentaamminecobalt(III) arsenate, which consists of mo
Populations of European starlings have declined over large parts of northern and western Europe during the last 20 years. It has been suggested that reduced availability of pasture in the agricultural landscape was one reason for this decline. To investigate this, breeding colonies for starlings were established in southern Sweden, in agricultural landscapes with different availabilities of pastur
The environmental impact of poultry mainly arises from their feed. Therefore, this study aimed to investigate the environmental impact of three Swedish poultry feeds and identify how their environmental performance could be improved. This was done with the method of life cycle assessment where the environmental impact categories of, climate change, acidification potential, eutrophication potential
Each year children and adults are injured in accidents caused by chemicals, usually due to incorrect use of the products. Studies have shown that children are more sensitive to chemical products and injuries that occur during childhood could cause lifelong consequences. In order to prevent accidents caused by chemicals it is important to label and package these products appropriately in accordance
Donated food is often fully edible, but improper handling can pose risks to food safety. The aim of this study is to investigate volunteers' knowledge of food safety within organizations that handle donated food and to identify areas for improvement without increasing the administrative burden. A qualitative method was used to gain a deeper understanding of volunteers' experiences and perc
Due to rapid urbanization and industrialization, cities have been seen as one of the main contributors to climate change and its negative impacts in recent decades. Many of the Nordic countries have experienced an increased number of torrential rains and floods in recent years, resulting in both property and environmental damage as well as possible negative effects on the well-being of citizens. E
There is scientific consensus today on the importance of local climate work. Many studies have investigated the mechanisms behind effective climate work and what makes some cities and large municipalities the frontrunners in driving progressive climate agendas. While this area of local climate work is well researched there is little research about how climate work looks like in small (non-rural) m
