Kemisk vittring kallas processen när mineralkorn löses upp och sönderdelas i molekyler eller atomer. Det är en viktig process, bland annat för att den frigör ämnen som skyddar marken från försurning och som fungerar som näringsämnen för växter. För de så kallade baskatjonerna kalium, kalcium, magnesium och natrium är vittringen i marken bland de största källorna. Framför allt de tre förstnämnda baBase cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. One of the largest inputs of base cations to soils is minerals weathering, which makes it an important process. It is, ho

The emerging notion of hematopoietic stem and progenitor cells (HSPCs) as a low-primed cloud without sharply demarcated gene expression programs raises the question on how cellular-fate options emerge and at which stem-like stage lineage priming is initiated. Here, we investigate single-cell chromatin accessibility of Lineage-, cKit+, and Sca1+ (LSK) HSPCs spanning the early differentiation landsc

The numerical simulation of the induction heating process can be computationally expensive, especially if ferromagnetic materials are studied. There are several analytical models that describe the electromagnetic phenomena. However, these are very limited by the geometry of the coil and the workpiece. Thus, the usual method for computing more complex systems is to use the finite element method to

OBJECTIVE: To describe data completeness, targeting and reliability of the Swedish version of the Spinal Cord Independence Measure Self-Report (s-SCIM-SR). DESIGN: Translation and reliability study. SUBJECTS: Programme participants (n = 48) and peer mentors (n = 42) with spinal cord injury enrolled in the INTERnational Project for the Evaluation of "activE Rehabilitation" (inter-PEER). METHODS: Th

Aim: The hormone osteocalcin influenced neurodevelopment and cognition in mice models; this human study explored potential associations between total serum levels in human infants and neurodevelopment at 4 years of age. Methods: The data were based on two Swedish birth cohorts from 2008 to 2009. We followed 158 healthy full-term vaginal births (51% girls) by measuring serum osteocalcin in cord blo

Despite increased awareness of the urgency to respond to climate change and to promote sustainable development, there are few powerful initiatives that are decisively shifting urban development in a sustainable, resilient and low-carbon direction. This Special Volume of the Journal of Cleaner Production explores sustainable urban transformation focusing on structural transformation processes – mul

It is challenging for the food industry to deliver products that satisfy consumers changing desires and needs. Baobab is a fruit that holds potential for the development of trendy food products due to its rich nutritional profile and unique rheology. Unlike most fruits, it contains a dry pulp with a moisture content of 11-12 % (Phytotrade, 2008). Despite these features, baobab has been overlooked

Sammanfattning Vi har gjort en kvalitativ studie och intervjuat individer med en tidigare missbruksproblematik och kriminellbakgrund. Alla utom en av intervjupersonerna har deltagit i ett 12-stegsprogram. Det finns hjälp att få som missbrukare genom behandling, men det är ändå inte alla som klarar av att sluta fast den hjälpen finns. Det är viktigt och intressant att undersöka varför det är så. VWe have made a qualitative study that started from interviewees with substance abuse problems. All of the interviewees have a background as criminals and addicts and three of them have participated in twelve-step program. There is treatment that is intended to support and help addicts, but it's still not all that manage to get out of their addiction. That makes it important and interesting to

This thesis investigates the possibility of the mediated city providing a space for resistance in everyday life in a society where free speech channels are strictly controlled. The case studied in this thesis is the phenomenon of a group of fans of a singer who has been banned by the government in mainland China writing graffiti in public urban space on Rehe Road in Nanjing to express their love a

Syftet med studien var att nå en ökad förståelse för hur par- och familjeterapin påverkas av att bedrivas online samt att undersöka par- och familjeterapeuters upplevelser av onlineterapi. Semistrukturerade intervjuer genomfördes med åtta legitimerade par- och familjeterapeuter som i sin verksamhet har erfarenhet av par- och/eller familjeterapi online. Materialet analyserades med tematisk analys oThis study aims to increase understanding of how couple and family therapy are affected by being carried out online, and to explore couple and family therapists’ experiences of online therapy. Semi-structured interviews were conducted with eight accredited couple and family therapists with experience of practicing therapy online. The data was subjected to thematic analysis, and nine themes were id

Abstract Author: Jakob Rönnqvist Title: Värdegrundsarbete inom handikappomsorgen – en studie om medarbetares syn på värdegrundsarbete Supervisor: David Hoff In recent times, ethic related questions have come to play a major role within organiza-tions and corporations. The introduction to basic value work can be seen as a conse-quence of this process. Previous research indicates that basic value

The competition policy is an area of law that moulds itself according to the structure of the society and evolves by habitually adjusting to the dynamics of the national economies. Due to various historical contexts as well as to the distinct economic systems, the competition law in EU and Japan walked on different paths at different rhythms. However, in both jurisdictions the dissimilarities have

Reduction of the cleaning time is an important issue for companies using large tanks. A common solution is a stationary pipe going into the tank with a cleaning nozzle mounted on the end. Today the spray pattern of most cleaning systems is fixed. It would be beneficial to adjust the cleaning cycles so that the most soiled places of the tank get extra attention without increasing the total cleaning

OBJECTIVE: Thyroid hormones control a variety of processes in the central nervous system and influence its response to different stimuli, such as ischemic stroke. Post-stroke administration of 3,3',5-triiodo-L-thyronine (T3) has been reported to substantially improve outcomes, but the optimal dosage and time window remain elusive.METHODS: Stroke was induced in mice by transient middle cerebral art

Title: An Absolut icon – To see beyond the label Seminar date: 2012-01-12 Course: FEKH95 Business Administration: Degree Project Undergraduate level, 15 University Credit Points (UPC or ECTS-er) Authors: Fabian Frankenius, Viktor Siewert Holkert and Joel Sverneborn Advisor: Clara Gustafsson Key words: Icon, Brands, Myth, Brand Equity, Authenticity. Purpose: How can we improve our understanding of

More recently, the number of elderly immigrants has increased. This means that Sweden is faced with new challenges. The purpose of this study was to illustrate how the elder immigrants general situation in Helsingborg looks like, as well as how social workers work to integrate this target group. Furthermore, I wished to have an answer on whether social workers feel that there is a continuing need

This paper suggests that pre-transiton mobilisation and collective bargaining creates post transiton success. It also examines how the fragility of a gender identity often results in fragmentation of crosscutting women's organisations once democracy is established, resulting in poorer cooperation between women and effectively poorer struggle for gender equality. It is a case study that takes u

Taking in to consideration the countless human rights violations and impunity in Africa, there is not a shred of doubt about the dire need for effective human rights protection mechanisms at continental level. This concern has mainly increased due to the Africa Commission’s poor track record of enforcement of human rights norms in the region. Hence, it is in the effort to cure the ills suffered by

This study focuses on one of the critical design parameters of lean premixed (LPM) combustors-the air split ratio (ASR) between the pilot and main stages. The effect of the air split ratio on thermoacoustic instability is experimentally studied based on a centrally staged model combustor. It is found that the thermoacoustic instability is suppressed with the ASR higher than 20%. The acoustic modes
