Berättelser om Ukraina

The conflict in Ukraine is not only a conflict in a strictly traditional or material sense, in terms of a quest for territory or over military power. Rather, it is a conflict where the battlefield is located in the United Nations Security Council, and the battle is a verbal war between ambassadors and diplomats about conflicting narratives and how the conflict should be defined. In this thesis, a

Statistical power considerations in genotype-based recall randomized controlled trials

Validation of gene × environment interaction results from epidemiological studies in randomized clinical trials (RCTs) is usually hampered by insufficient statistical power. Genotype-based recall (GBR) refers to the design of studies in which subgroups of the population are selected based on their genotypes. In this thesis we test if a GBR approach of recruiting two groups of participants with dis

Energipålar - Termiskt responstest på prefabricerad energipåle i betong

Energipålar är grundläggningspålar kombinerade med kollektorslangar som används som vertikala markvärmeväxlare. De har sedan 1980-talet använts i Centraleuropa, och används även frekvent i England. I Sverige har energipålar ännu inte slagit igenom, men de större byggföretagen börjar nu intressera sig för denna typ av grundläggning. En fördel med energipålar jämfört med konventionella bergvärmebruEnergy piles are deep foundation piles combined with collector pipes. They are used as vertical ground heat exchangers, and have been used since the 1980s in Central Europe and frequently in England. Energy piles have not yet had its breakthrough in Sweden, but right now the bigger construction companies have turned their eyes to this type of deep foundation. One advantage with energy piles, when

Soft Europeanisation of Work-Family Reconciliation Policy-Making? Social, Policy and Political Learning among German MPs

The EES, Lisbon and Europe 2020 are the most relevant soft law strategies promoting the improvement of work-family reconciliation-related policies in the EU Member States. In this study, the cases of the German Elterngeld reforms are applied to scrutinise the influences of these three strategies on domestic policy-making. Thus, this research work is based on the theoretical framework of soft Europ

Buddhismens Baksida - En fallstudie över Buddhistisk nationalism i Burma och Thailand

Recent years has seen an increase in the support for the radical right all over Europe, Sweden not excluded. The debate has ranged from the dangers of islamization, to the slightly more philosophic question as to who is to be part of the nation. However, at the other side of the world, another form of nationalism, one seldom discussed, is seemingly growing in strength and consequences – the Buddhi

Studies of the cellular dynamics of the FilP cytoskeleton in Streptomyces hyphae

FilP- Ett protein med förstärkande egenskaper Bakterier finns i alla möjliga former och storlekar. Ett släkte bakterier som alla har varit i kontakt med, de flesta utan att veta om det, är Streptomyces. Streptomyces är en jordlevande bakterie som bildar ett nätverk av långa hyfer och är orsaken till att jord luktar som den gör. Men det är inte för sin jorddoft som Streptomyces är mest känd, det ä

Complex formed in the system hydrophobically modified polyethylene glycol/methylated alpha-cyclodextrin/water. An NMR diffusometry study

In aqueous solutions hydrophobically modified polyethylene glycol (HM-PEG) forms a transient polymer network held together by intermolecular hydrophobic associations. In the present investigation we have used NMR-diffusometry to study how the addition of methylated alpha-cyclodextrin (M-alpha-CD) influences the polymer network. The addit on of M-alpha-CD resulted in an increased mean self-diffusio

Dibenzyl sulfide at 150 K

The mol-ecule of the title compound, C14H14S, lies on a crystallographic twofold axis running through the central S atom, and hence mol-ecules have exact C-2 mol-ecular symmetry. Density-functional theory calculations reveal that the energy-optimized mol-ecular structure in the gas phase is close to that observed in the crystal structure. The crystal packing is dominated by double chains running a

Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics

Popular Abstract in Swedish Det har traditionellt sett varit mycket svårt att genomföra förbränningsstudier i motorer, men i och med laserns introduktion har nya möjligheter öppnats. Under de senaste 20 åren har lasern blivit ett allt viktigare hjälpmedel, och ett stort antal laser baserade mätmetoder har utvecklats. Det är nu möjligt att mäta temperaturer, ämneskoncentrationer, hastighetsfält ochMulti-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium a

Secondary thalamic lesions after ligation of the middle cerebral artery: an ultrastructural study

Earlier light microscopic, immunocytochemical and morphometric investigations indicate that noxious substances transported with the vasogenic edema from hemispheric infarcts influence the character, timing and extent of the secondary thalamic lesions. The object of the present study was to analyze the ultrastructure of the secondary damage and the cytolytic nerve cell change which ensues in the th

Abnormal vascular network complexity: a new phenotypic marker in hereditary non-polyposis colorectal cancer syndrome

BACKGROUND: Hereditary non-polyposis colorectal cancer (HNPCC) (Lynch cancer family syndrome I (LCFS1) and II (LCFS2)) is one of the most common hereditary cancer disorders. HNPCC results from dominantly inherited germline mutations in mismatch repair (MMR) genes, leading to genomic instability and cancer. No predictive physical signs of HNPCC are available to date. AIMS: Increased complexity in t

Glioblastoma multiforme in the microscope: Diagnostic features of importance for prognosis and treatment.

Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,

Positional and functional mapping of a neuroblastoma differentiation gene on chromosome 11

Background: Loss of chromosome 11q defines a subset of high-stage aggressive neuroblastomas. Deletions are typically large and mapping efforts have thus far not lead to a well defined consensus region, which hampers the identification of positional candidate tumour suppressor genes. In a previous study, functional evidence for a neuroblastoma suppressor gene on chromosome 11 was obtained through m

On the modelling of drop behaviour in siphon riser tubes in paper drying cylinders

A theoretical model has been developed for the drop behaviour in siphon riser tubes in paper drying cylinders. Analytical solutions to the equations are presented for the systems air-water at atmospheric pressure and saturated steam-water. Numerical simulations are performed for a large number of input data. Calculated drop trajectories indicate that the drops travel only a small part of the riser
