A humus soil with a pH of 4.9 was fumigated with chloroform for 5 h, after which only 1% of the initial bacterial activity remained. Half of the fumigated soil was limed to a pH of 7.5. Both the unlimed soil (UL) and the experimentally limed soil (EL) were inoculated with unfumigated (UL) soil or a field-limed (FL) soil with a pH of 6.1. The pH tolerance and activity of each developing bacterial c
During the last two decades, the synthesis of silica with an ordered mesoporous structure has been thoroughly explored. The basis of the synthesis is to let silica monomers polymerize in the presence of an amphiphilic template component. In the first studies, cationic surfactants were used as structure inducer. Later it was shown that pluronic copolymers also could have the role. One advantage wit
Survival after childhood cancer has improved substantially over recent decades. Although cancer in childhood is rare increasingly effective treatments have led to a growing number of long-term survivors. It is estimated that there are between 300,000 and 500,000 childhood cancer survivors in Europe. Such good survival prospects raise important questions relating to late effects of treatment for ca
Using in situ surface-sensitive electron microscopy performed in real time, we show that the dynamics of micron-sized Ga droplets on Ga P(111) can be manipulated locally using Au nanoparticles. Detailed measurements of structure and dynamics of the surface from microns to atomic scale are done using both surface electron and scanning probe microscopies. Imaging is done simultaneously on areas with
This study documents the terrestrial palynological record at the John's Nose section, a new Cretaceous-Paleogene (K-Pg) boundary site in North Dakota, USA. In addition to Mud Buttes and Pyramid Butte, John's Nose represents the third K-Pg section in southwestern North Dakota that preserves direct evidence of the Chicxulub asteroid impact, allowing for direct comparison over the timing and trends o
Successful further development of superhigh-constrast upconversion (UC) bioimaging requires addressing the existing paradox: 980 nm laser light is used to excite upconversion nanoparticles (UCNPs), while 980 nm light has strong optical absorption of water and biological specimens. The overheating caused by 980 nm excitation laser light in UC bioimaging is computationally and experimentally investi
Heart fatty acid binding protein (HFABP) is expressed in the brain and is elevated in cerebrospinal fluid (CSF) from patients with several forms of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease with dementia, Lewy body dementia, vascular dementia (VaD), and Creutzfeldt-Jakob disease. However, whether HFABP in CSF is a stable biomarker or if it can help predict co
The human molecular chaperone protein DNAJB6 was recently found to inhibit the formation of amyloid fibrils from polyglutamine peptides associated with neurodegenerative disorders such as Huntington's disease. We show in the present study that DNAJB6 also inhibits amyloid formation by an even more aggregation-prone peptide (the amyloid-beta peptide, (Aβ42)(2), implicated in Alzheimer's disease)in
En ofta använd behandlingsmetod mot cancer är strålbehandling. Inför en sådan behandling undersöks patienten ofta med en typ av röntgenundersökning som kallas datortomografi (eng. computed tomomgraphy, CT). Röntgenbilderna visar hur mycket av strålningen som absorberas av kroppen, vilket innebär att man tydligt ser skillnad mellan ben, som absorberar mer av strålningen än vävnad och luft, som strå"Introduction; The aim of this study was to examine the possibilities for MRI-based radiotherapy treatment planning. The work included evaluation of geometric image distortions in MR-images, investigations of how segmentation of bone could be performed from images acquired with the ultra short time of echo (UTE) pulse sequence and assessment of dosimetric differences between treatment plannin
Detta arbete har syftat till att göra en situationsstudie av dissipation beräknad i HIRLAM, en numerisk prognosmodell, över Danmark och att ge författarna kunskap om fenomenet turbulens. Studien gjordes genom att bearbeta data erhållen från HIRLAM i MATLAB. Den nedersta delen av troposfären där jordytan har en påverkan på atmosfären kallas för gränsskiktet. När vinden blåser i gränsskiktet kommer This case study aimed at analyzing dissipation calculated in HIRLAM, a numerical forecast model, over Denmark and to give the authors more knowledge about the phenomenon of turbulence. The study was done by processing data obtained from HIRLAM in MATLAB. The lowest part of the troposphere where the surface of the earth has an impact on the air is called the planetary boundary layer. When the wind
Malmö är en stad som genomsyras av människor och kulturer från olika delar av världen. I den kulturella mångfalden finns tätgrupper med en nära förankring i sin etniska bakgrund. Min uppsats beskriver hur människor med persisk bakgrund förhåller sig till sina persiska musiktraditioner och sin kulturella identitet i det svenska samhället. Studien har inspirerats av mina egna erfarenheter av persiskTo preserve the origin of a musical culture Malmo is a city that contains a lot of people from different parts of the world. There are certain groups with a close bond to their ethnicity. My study is a description of how people with persian roots relates to their persian musical traditions and their cultural identity in the swedish society. The study is inspired by my own experiences of Persian mu
This Master's thesis aims to investigate librarians' identity construction through the study of their narratives about themselves and their lives. We want to understand in what way the education in Library- and Information science contributes to shape the students professional identity and how these identities then continue to be transformed when they enter their professional lives. We ass
Introduction: Wearable sensors measuring bodily movements used in free-living conditions may help predict falls in older persons. Assessing their use in this context is essential to identify potential challenges related to fall risk screening. Therefore, this study aimed to assess the feasibility of conducting a prospective study comparing self-rated and wearable sensor-based measures for the asse
Which expectations did leading debaters place on fiction as an instrument in achieving societal changes hoped for by introducing the Public library? How can the value of fiction be described in relation to the mission of the Public library, according to these moulders of public opinion? Place and timeframe for this thesis is Sweden around the years 1905-1912 (period of formation of the Public libr
China has had an unbelievable economic development over the last 25 years. Their gross domestic product (GDP) has increased by more than 9% yearly. Since the middle of the 1980’s this trend has become more and more dependent on China’s private firms. China’s private firms are much more effective than their counterpart state-owned enterprises. Despite this fact, private firms are still treated very
Today, 14 years have gone since the whole world turned their backs on Rwanda, the small country in East Africa, during a time when its population needed us the most. These were the same nations that already after the Second World War had made a promise about ''Never Again'', then meaning that they would never again allow another attempt to exterminate an entire ethnic group. It was
The Kurdish economy is today heavily dependent on hydrocarbons exports. Current trends are that hydrocarbons exporting and processing countries, as well as interest groups within these countries, are pushing to expand production and maximise profits while this is still possible. The magnitude and observed acceleration of the present climate emergency - with major impacts both in terms of loss of c
In the setting of transplantation, T cells are deliberately depleted to prevent allograft rejection. However, this IL-7 activates the accelerated proliferation of effector memory T cells, which are the predominant mediators of graft rejection. Multipotent adult progenitor cells (MAPC) have been previously shown to modulate the response of T cells to IL-7, in vitro but not in vivo. Here, for the fi
Only very recently has the concept of circular economy gained momentum in the public sphere, and inspired consequent research. Within the field of built environment, the debate is even more nascent. This study aims at developing the definition of circular economy specifically for the purposes of the real estate sector. A definition of circular economy in real estate, is derived from the results of
