The combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden. With a chemical dose of 4 gAl3þ/m3 and 1.5 g/m3 cationic polymer as active material effluent water quality with regards to total phosphorous (Tot-P), suspenThe combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden.

This paper investigates whether the exports of different products by the same firm are systematically interconnected. Using Swedish firm-registry data from 1997-2011, I first document that the distribution of firm export sales is skewed towards their best performing products (‘superstars’). I then use a novel instrumental variable approach to identify if the ‘superstar’ products induce more trade This paper investigates whether the exports of different products by the same firm are systematically interconnected.

Oxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C. The stoichiometry of the reaction has been determined: [Tl(H2O)6]3++ SO2(aq)+ 2H2O →[Tl(H2O)6]++ HSO4–+ 3H+. The kinetics has been studied by use of stopped-flow spectrophotometry under pseudo-first-order conditions with eOxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C.

The impact climate and land-use changes have on the hydrological conditions in peat bogs and lakes is often complex, but of great importance for the carbon budget and biodiversity in these ecosystems. Links and feedbacks between raised bog water table depth, lake level, net precipitation, hydrometeorological indices, and radial tree growth have been studied and identified in the Rėkyva wetland com

This article explores how policy-makers are managing scientific uncertainty in policy-making. This is done through a case study of the Swedish climate change policy process from 1975 to 2007, based on interviews and an extensive review of official publications and documents. The study shows that scientific uncertainty played a very marginal role in the development of Swedish climate politics. When

Background: Relapse of hepatitis C virus (HCV) infection after liver transplantation (LT) is universal. Tolerance for treatment with pegylated-interferon (peg-IFN) and ribavirin (RBV) is suboptimal and withdrawals due to adverse events frequent. We sought to improve tolerance for treatment to improve outcome. Methods: We used concentration-guided RBV dosing to achieve an intended 10 mu mol/L conce

Lentic water bodies (lakes and reservoirs) offer favorable conditions for silica (SiO2) burial in sediments. Recent global estimates suggest that (1) lentic SiO2 trapping is a globally important SiO2 flux, and (2) through reservoir construction, humans have dramatically altered river dissolved SiO2 (DSi) transport and coastal DSi delivery. However, regional to global scale patterns and controls of

Popular Abstract in Swedish Magnetisk resonanstomografi: Patienters upplevelser och betydelsen av anpassad information och förberedelse för vuxna och barn. Magnetisk resonanstomografi (MRT) har sedan tidigt 1980-tal ökat i betydelse och är idag en vanlig undersökning för både vuxna och barn. Undersökningen innebär att patienten ligger i en smal tunnel i magnetkameran och när bilderna tas hörs kraMagnetic resonance imaging (MRI) is becoming an increasingly common form of exami¬nation for both adults and children. Although it is non-invasive and considered painless, both adults and children experience anxiety during the examination. The technique is sensitive to motion and for that reason many children are anaesthetised. The aim of this thesis was to improve patient care through exploring a

A surface-sediment survey of pigments in 100 lakes in the Scandes Mountains, northern Sweden, was combined with a reconstruction of Holocene sedimentary pigments from Lake Seukokjaure to assess the major factors regulating phototrophic communities, and how these controls may have changed during the period from the deglaciation (similar to 9700 cal. years BP) to the present. The study area covers a

This project focuses on understanding creativity and its surroundings, along with the effects it can have on the mind. The goal was to inspire individuals to grow both physically & mentally throughout their creative processes. Research has been done through books, videos, articles, Internet and discussions. As well as an interview at a company about their creative workplace. Other research was

Följande rapport behandlar Östgötateatern i Linköping och skrivs som en del av kursen Brandteknisk Riskvärdering vid Brandtekniska avdelningen, Lunds tekniska högskola. Syftet med rapporten är att utvärdera personsäkerheten i byggnaden vid händelse av brand. Information om objektet fås genom ett platsbesök, varefter ett antal möjliga brandscenarion identifieras. Genom att utföra en grovanalys på d

After the French police managed to gain access to material from the encrypted communication service EncroChat, parts of the material were forwarded to the Swedish police. This resulted in a large number of people being sentenced to long prison terms. EncroChat is partly an encrypted communication service and partly an operating system that runs on smartphones. EncroChat is used by people who do n

Gold mining is widespread in the Colombian Amazon and negatively impacts biodiversity, climate, and social equity. While some claim that sustainable gold mining can address these issues, we have analyzed different narratives of sustainable gold mining, focusing on equity and power dimensions. Our research, conducted through participatory observation and interviews across scales between 2022 and 20
