Accurately quantifying soil base cation pool sizes is essential to interpreting the sustainability of forest harvests from element mass-balance studies. The soil-exchangeable pool is classically viewed as the bank of "available" base cations in the soil, withdrawn upon by plant uptake and leaching and refilled by litter decomposition, atmospheric deposition and mineral weathering. The operational

Background: Informed consent is a prerequisite for patients included in clinical trials. Trial design, inclusion criteria and legal requirements are increasingly complex. This complexity challenges design and delivery of written and oral trial information to ensure understandable information. To evaluate the level of concordance between patients' and informing physicians' assessments regarding pat

1. Measurements of membrane capacitance, as an indicator of exocytosis, and intracellular Ca2+ concentration ([Ca2+]i) were used to determine the Ca2+ dependence of secretion in single pancreatic B-cells. 2. Exocytosis was dependent on a rise in [Ca2+]i and could be evoked by activation of voltage-dependent Ca2+ currents. The threshold for depolarization-induced release was 0.5 microM [Ca2+]i. Onc

Although bottom water hypoxia (O2 −1) is presently widespread in the Baltic Sea coastal zone, there is a lack of insight into past changes in bottom water oxygen in these areas on timescales of millennia, and the possible driving factors. Here, we present a sediment-based environmental reconstruction of surface water productivity, salinity and bottom water oxygen for the past 5400 years at Gåsfjär

The closed chamber technique is widely used to measure the exchange of methane (CH4) and carbon dioxide (CO2) from terrestrial ecosystems. There is, however, large uncertainty about which model should be used to calculate the gas flux from the measured gas concentrations. Due to experimental uncertainties the simple linear regression model (first-order polynomial) is often applied, even though the

Då vi lyser med ljus på något ämne kan det huvudsakligen hända tre olika saker; ljuset går rakt igenom ämnet (transmitteras), ljuset tas upp av ämnet (absorberas) eller ljuset ändrar riktning i ämnet (sprids). Vi ser alla dessa effekter hela tiden och de är självklara i vårt vardagliga liv. Ett exempel är de färger vi uppfattar och som utgör en stor del av de synintryck som vi får från vår omgivniLight interacting with biological matter is dominated by light scattering; biological matter is turbid. In order not to harm the natural structure of biological matter, visible light can be used to investigate it, and to avoid the light being absorbed from e.g. blood and water, an optical window in the longer wavelength region of the visible spectrum is used, that is, red light. One can actually c

Augustenborg storm water system has become well known for its incorporation of urban green spaces. Open storm water system was developed in late 1990s by disconnecting impervious surfaces from combined sewers as a result of flooding problem in the basements after heavy rain events. The open storm water management system consists of open channels and ponds, a small wetland, green infiltration areas

“1000 Extra” is a project that takes off in the sub optimal conditions that city planning in the 20-th century has left behind for the future. First and foremost looking at the conditions of residential areas planned based on doctrines stemming in modernism, the project proposes desnsifying the not-so-dense areas in Lund, consisting of row houses and other residential buildings in the same categor

Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. Treated wastewater being a major source of ingress of micropollutants into the aquatic environment, the current standards do not stipulate

This thesis investigates how urban experimentation is governed in the new development district in Sege park in Malmö. Together with with private developers and a local NGO the municipality test and experiment with solutions for how the sharing economy can contribute to reduce the future resident’s climate impact and living costs. By using the theoretical lens of governmentality this thesis focusse

The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. The usage of remote sensing (RS) can aid in quantifying forest characteristics and large-scale changes in forest ecosystem

Segregation är ett vanligt fenomen som uppstår över hela världen. De negativa konsekvenserna av boendesegregation har visat sig vara många för de som bor i mindre välbärgade stadsdelar. Bland konsekvenserna finns bland annat hälsorelaterade motgångar, men även sämre förutsättningar under skolgången och i det framtida arbetslivet har konstaterats. Sydafrika lämpar sig väl för att studera segregatioSegregation is a common phenomenon arising worldwide. Residential segregation has been shown to have several negative consequences for people living in less wealthy neighbourhoods, such as health-related setbacks and being less likely to cope with school. South Africa is an especially well-suited country to study segregation and methods to counteract it to achieve better integration and more harmo

I denna rapport undersöks hur olika åtgärder påverkar trafiksituationen för oskyddade trafikanter i korsningar. Undersökningen görs främst utifrån de tre aspekterna trafiksäkerhet, framkomlighet och omgivande miljö. Arbetet omfattar sex korsningar i Helsingborg som har byggts om vid olika tidpunkter och där olika åtgärder har vidtagits. För att göra en bedömning av åtgärdernas påverkan på trafiksäThis report examines how different traffic improvement measures affect the traffic situation for vulnerable road users at intersections. The survey is conducted mainly based on the three categories of road safety, accessibility and the surroundings. The work investigates six intersections in Helsingborg that have been rebuilt at different times and where different measures have been taken. To eval

This work aimed to characterize single chain fragment variables (scFvs) against S100A7 and Calprotectin, proteins part of the Ca2+ binding S100 family that have been associated with inflammatory diseases and cancer. The mechanisms governing the physiological functions of S100 proteins are not fully understood, but it is known that many of them contribute to maintaining homeostasis in the intracell

Freshwater systems are active components of the global carbon cycle and contribute to global CO2 emissions. Freshwater studies in the Arctic are underrepresented, especially regarding lakes and their Dissolved Organic Carbon (DOC) reactivity and composition dynamics. DOC is a main part of DOM (dissolved organic matter), which drives processes central to carbon cycling, influences chemical and biol

Non-fungible tokens (NFTs) are a type of cryptocurrency that consist of unique, non-exchangeable tokens, which are traded on a blockchain. These unique tokens are associated with digital assets such as images, art, videos, or music. With the rapid rise of NFTs’ popularity in 2021, a community established around trading, selling, and collecting of NFTs. This study explored the NFT community at larg

Syftet med denna rapport var att problemen med underhållsprogram skulle undersökas och sedan till en viss mån lösas. Det fanns 3 frågeställningar i denna rapport och dessa var vilka problem som användarna upplever med underhållsprogram, hur problemen kan lösas och vad underhållsprogram används till idag och vad dessa kommer användas till i framtiden. Undersökningen genomfördes genom intervjuer medThe purpose of this report was to investigate and to some extent resolve the problems with maintenance programs. There were 3 aims in this report and these were what problems the users experience with maintenance programs were going to be enlightened, that the problems were going to be solved and what maintenance programs are used for today and what they will be used for in the future were to be i

The accurate diagnosis of malaria is crucial for ensuring an effective treatment and combating the developing drug resistance of the parasite. The standard diagnostic method, consisting of light microscopy in combination with Giemsa-staining, requires manual examination through a trained clinician. This is time-consuming and prone to human error. While emerging diagnostic innovations can overcome
