Elevated arsenic (As) in soil is of public concern due to the carcinogenicity. Phosphorus (P) strongly influences the adsorption, absorption, transport, and transformation of As in the soil and in organisms due to the similarity of the chemical properties of P and As. In soil, P, particularly inorganic P, can release soil-retained As (mostly arsenate) by competing for adsorption sites. In plant an
Begreppet grön demokrati har förts fram inom grön politisk teori som ett sätt att inkludera den naturliga världen i den politiska och på så vis komma förbi en föreställd mur som separerar människor och natur i moderniteten och ersätta den med en brygga mellan dem. Begreppet tänks också härbärgera kraften att omvandla samhället i hållbar riktning. I denna studie argumenteras att grön demokrati diskThe concept of green democracy has been advanced in green political theory as a way to include the natural world in the political and, by that, overcome an alleged wall, a fundamental disunity, separating humans and nature in modernity and substitute it with a unity of identity that would bridge the gap between them. It has also been vested with the coupled power to transform society in a sustaina
Blood parasites (Haemosporidia) are thought to impair the flight performance of infected animals, and therefore, infected birds are expected to differ from their non-infected counterparts in migratory capacity. Since haemosporidians invade host erythrocytes, it is commonly assumed that infected individuals will have compromised aerobic capacity, but this has not been examined in free-living birds.
HAMLET is a protein-lipid complex with a specific and broad bactericidal and tumoricidal activity, that lacks cytotoxic activity against healthy cells. In this study, we show that HAMLET also has general immune-stimulatory effects on primary human monocyte-derived dendritic cells and macrophages (Mo-DC and Mo-M) and murine RAW264.7 macrophages. HAMLET, but not its components alpha-lactalbumin or o
Periodic structures are known to produce passbands and stopbands for propagation of vibration energy within the frequency domain. Sources vibrating harmonically at a frequency within a passband can lead to propagation of energy through propagating modes over long distances. However, sources vibrating at a frequency within a stopband excite only nearfields in the form of attenuating and evanescent
Organic carbon burial in lake sediments plays an important role in the global carbon cycle, and is heavily affected by the terrestrial organic matter input. However, few studies have focused on long-term changes in terrestrial organic matter input to lakes in response to land-use changes. The aim of this study was to assess variations in sedimentary terrestrial organic matter over the last 1000 ye
Background: Medical devices are increasingly being reported to cause contact allergic dermatitis reactions. Objective: Review of patients with diabetes type I referred for suspected allergic contact dermatitis to insulin pump or glucose sensor systems. Method: We have reviewed 11 referred diabetes mellitus patients investigated for allergic contact dermatitis reactions to medical devices and speci
Bilismen orsakar en mängd problem i våra städer. Det handlar dels om negativa effekter på människors hälsa på grund av skadliga partikelutsläpp, buller, trafikolyckor och stillasittande, dels om platsen den tar i anspråk vilket leder till trängsel och att värdefull mark tas i besittning av väginfrastruktur och parkeringsplatser. I ett större perspektiv bidrar biltrafiken även till utsläpp av växthTraffic accumulated by cars is responsible for considerable problems in our cities. The problem is partly about the negative effects on human health due to harmful particulate emissions, noise, traffic accidents and sedentary lifestyles, partly about the space it occupies, which leads to congestion, and the fact that valuable land is taken up by road infrastructure and parking lots. In a bigger pe
Denna studie kretsar kring pheriwale, en grupp egenföretagare inom Indiens stora informella ekonomi. Pheriwale har livnärt sig på handel i Delhi under nästan ett sekel och sysslar med handel med begagnade kläder. De är en av de mest tydligt kvinnodominerade grupperna av gatuhandlare och -försäljare i staden. Genom att knacka dörr hos invånare i staden och förorten sysslar de med byteshandel och saThis study revolves around the working lives of pheriwale, a group of self-employed traders within India’s vast informal economy. Pheriwale have been trading in Delhi for nearly a century and are involved in the second-hand clothing trade. Among the wide variety of street vendors and traders in the city, pheriwale are one of the most visibly women-dominated. They offer a door-to-door service, coll
Biochar produced in cookstoves has the potential to contribute to negative carbon emissions through sequestration of biomass carbon while also providing other benefits for sustainable development, including provision of clean renewable energy and increased yields in tropical agriculture. The aim of the reported research was to estimate effects on food production, household energy access and life c
INTRODUCTION: Diabetes mellitus (DM) and colorectal cancer (CRC) share some risk factors, including lifestyle and metabolic disturbances. We aimed to provide in-depth information on the association of CRC risk, especially early-onset CRC, with DM, family history of CRC, and age at DM diagnosis. METHODS: A nationwide cohort study was conducted using Swedish family cancer data sets, inpatient, and o
The mechanisms underlying M. fortuitum-induced pathogenesis remains elusive. Using headkidney macrophages (HKM) from Clarias gariepinus, we report that TLR-2-mediated internalization of M. fortuitum is imperative to the induction of pathogenic effects. Inhibiting TLR-2 signalling alleviated HKM apoptosis, thereby favouring bacterial survival. Additionally, TLR-2-mediated cytosolic calcium (Ca2+)c
This paper contains a quantification and decision theoretical optimization of the posterior utilities for several options for monitoring campaigns on the particular case of fatigue life predictions of an orthotropic steel deck. The monitoring campaigns are defined by varying monitoring durations and phases. The decision analysis is performed with real data from the Structural Health Monitoring (SH
Identifying optimal inspection and repair strategies for offshore jacket structures is a challenging task. We present an approach, which is based on recent developments in the field of risk-based operation and maintenance planning at the structural system level. The approach utilizes heuristics to define inspection and repair strategies at the system level and to reduce the search space of possibl
Over the last decade, Unmanned Aerial Vehicles (UAVs) have been used for monitoring construction and operation of civil infrastructure, as well as industrial facilities and power plants. Their operational simplicity along with time-and-cost-related benefits have already rendered them attractive for structural surveying. Nevertheless, the field of UAV research currently lacks a targeted employment
A software prototype is developed for assessing and updating the reliability of single-cell prestressed concrete box girders subjected to chloride-induced reinforcement corrosion. The underlying system model consists of two integrated sub-models: a condition model for predicting the deterioration state of the box girder and a structural model for evaluating the overall system reliability. The cond
Inspections are an efficient means of enhancing the reliability of redundant structural systems subjected to fatigue.To investigate the effect of such inspections, we represent the deterioration state of a Daniels system by means of a probabilistic fatigue crack growth model of all elements, which considers stochastic dependence among element fatigue behavior. We include inspection results in the
Prototypes of wind turbines of the megawatt class are to be built and tested until 2008 within a German offshore wind energy test field in the North Sea (ALPHA VENTUS). To ensure a high operational reliability of offshore wind turbines with economically acceptable repair and maintenance efforts, comprehensive diagnosis and supervision concepts are required. Automatic monitoring systems will be an
Autoimmune hepatitis (AH) and primary biliary cirrhosis (PBC) are autoimmune diseases (AIDs) targeting cellular components of the liver. Being rare diseases, limited data are available about familial risks among these AIDs (concordant) or between them and other AIDs (discordant). We aimed to carry out an unbiased study on these AIDs based on medically diagnosed patients. We collected data on patie
