This pilot-scale study investigates the possibility of using nanofiltration after ultrafiltration to improve lignin recovery from kraft black liquor in a pulp mill. The nanofiltration step can increase overall lignin recovery and provide a clean permeate that could be used in the smelt dissolving tank to produce green liquor. Nanofiltration of kraft black liquor ultrafiltration permeate was perfor

Förlust av biologisk mångfald är ett av de största hoten mot ekosystem och derasfunktioner. Nästan 500 arter i den marina miljön i Sverige anses idag vara hotade ellersårbara. En av dessa är Sveriges enda val, tumlaren (Phocoena phocoena), som lever längs hela Sveriges kust och rör sig över stora områden i sin jakt på fisk att äta. Mänsklig påverkan, framför allt genom oavsiktliga bifångster vid gThe harbour porpoise (Phocoena phocoena) is a small toothed whale with a mainly coastal distribution in the northern hemisphere. As a marine top predator, the species can act as an indicator for early warning signs of ecosystem changes. At the same time, harbour porpoises are globally threatened by human activities and in need of conservation. Successful protection of harbour porpoises requires un

The Amsterdam 2022 International Consensus Statement on Concussion in Sport (6th International Conference on Concussion in Sport) was the first Concussion in Sport Group (CISG) consensus to consider the para athlete.1 To date, a lack of research in para sport on most aspects of concussion has prevented the development of evidence-informed consensus on any aspects of concussion care for para athlet

This article investigates how things given to local temples generate material, karmic, and emotional excess in contemporary Japan. What, how, and why people “store” at local Buddhist temple tell a story of a community and how people’s individual material histories become matters of communal concern and local heritage-making practices. While walking a fine line between memory and decommissioning of

Children born to enemy soldiers, so-called “children born of war,” are vulnerable to displacement. The contested repatriations of the children of Scandinavian mothers and foreign fighters from Syria in the wake of the fall of the “Islamic state” in March 2019 are point in case. Norway, Denmark, and Sweden at first delayed and then only hesitantly or selectively supported their return – as Norway a

Samhällets storskaliga digitalisering har inte bara påverkat människors vardag och yrkesliv, den har också påverkat undervisning och lärande på ett genomgripande plan – inte minst när det gäller det kunskapsbyggande som tar plats i skolor och klassrum, under ledning av lärare. Under de senaste decennierna har pappersbaserat material och laborationsutrustning ersatts av applikationer och digitala vThis thesis is about learning. It is about how younger students (6–12 years old) usethings on-screen (representations, feedback, or virtual characters) and how they handle digitalised learning environments. I have explored this subject using many perspectives and theories, not only focusing on handheld tools and physical or virtual materials, but also on the social interactions behind the screens,

In Sweden, Finland, Norway, and Denmark, the contact person intervention (CPI) is declared for children and youth in national legislation. The CPI is based on a relationship between the child and a volunteer adult who provides support to the child in need in different life situations. In this review, we summarise how the CPI within child welfare services has been studied and defined in four Nordic

Genetic variation at the 19q13.3 KLK locus is linked with prostate cancer susceptibility in men. The non-synonymous KLK3 single nucleotide polymorphism (SNP), rs17632542 (c.536 T > C; Ile163Thr-substitution in PSA) is associated with reduced prostate cancer risk, however, the functional relevance is unknown. Here, we identify that the SNP variant-induced change in PSA biochemical activity mediates

InBi(0 0 1) is formed epitaxially on InAs(1 1 1)-A by depositing Bi onto an In-rich surface. Angle-resolved photoemission measurements reveal topological electronic surface states, close to the M high symmetry point. This demonstrates a heteroepitaxial system entirely in the III–V family with topological electronic properties. InBi shows coexistence of Bi and In surface terminations, in contradict

We present a detailed depth-sensitive study of the evolution in correlated electron behavior from the surface of the prototypical correlated oxide, SrxCa1-xVO3, to its bulk. Photoemission measurements of varying surface sensitivity are employed to directly compare both the spectral weight and energetics of the correlated electron features, and resonant soft x-ray emission spectroscopy is used as a

(Ga,Mn)As is a model diluted ferromagnet system in which the atomic spins of Mn ions are ferromagnetically arranged due to the exchange interaction with valence band holes. An important tecchnological concern regarding this system has been approaches that might result in reduction of the density of Mn interstitial and increase in the content of Mn in order to make the system practically feasible.
