Popular Abstract in English Figure 1: Electron microscopy image of mesoporous material seen from above. The left image shows a possible shape of a silica particle (scale bar: 1 μm). The right image shows the mesopores in the particle (grey color) with the silicon dioxide walls (black color) (scale bar: 150 nm). Poly(N-isopropylacrylamide) (PNIPAAM) is a polymer that can provide the active part forMesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). This work addresses the following issues. i) Surface grafted PNIPAAM was found to be loca

This thesis is about the problem of how sensory qualities relate to neural states or processes. I shall try to present an account of why dualism appears to be an attractive and intuitive position, but also point out why dualistic intuitions may be misleading. A relatively common view in philosophy of mind is that accounts of how sensory qualities relate to neural states and processes involve an ex

Popular Abstract in Swedish I centrum för avhandlingen står det fotografiska porträttet. Min utgångspunkt har varit att kombinera olika teorier om kön med intresset för fotografi. Syftet har varit att visa hur fotografiska porträtt under perioden 1850-1910 i olika sociala och kulturella relationer medverkade till att formulera skilda bilder av vad en kvinna var. För att kunna göra det jämför jag f"Visiting Reality: Photography and Gender at the End of the Nineteenth Century" In the centre of the dissertation stands the photographic portrait. My point of departure has been to combine different theories of gender with an interest in photography. The aim has been to show how, during the period of 1850 to 1910, photographic portraits in different social and cultural relations contributed to f

The aim of the study was to investigate men with prostate cancer and benign prostatic hyperplasia (BPH) in comparison with men from the general population in aspects of presence and frequency of micturition problems in remembrance of prior to treatment and currently. Further, the aim was to investigate the impact of micturition problems on quality of life and the association with micturition probl

The relevance of particle mass, surface area or number concentration as risk indicators for health effects in non-industrial buildings has been assessed by a European interdisciplinary group of researchers (called EUROPART) by reviewing papers identified in Medline, Toxline, and OSH. Studies dealing with dermal effects or cancer or specifically addressing environmental tobacco smoke, house dust-mi

Sera from 410 patients from the Wuhan area in the central part of China with the diagnosis of chronic liver disease were analyzed for markers of hepatitis B, C and D virus infections. All sera, plus liver biopsy specimens from 188 of the patients, were also tested for hepatitis B virus DNA by polymerase chain reaction. Sixty-eight percent were HBsAg positive in serum, whereas 29% showed markers of

Popular Abstract in Swedish I denna avhandling diskuteras olika aspekter av tillverkning av nanostrukturer med nanoimprint litografi (NIL). Detta är en relativt ny metod som möjliggör snabb tillverkning av högupplösta strukturer på stora ytor. För att skapa dessa strukturer med NIL använder man sig av mekanisk deformation av mönstringsmaterialet. Detta skiljer sig från de mer etablerade mönstringsThis thesis describes different aspects of nanotechnology manufacturing with nanoimprint lithography (NIL), a relatively new nanofabrication tool capable of high resolution and high throughput. Surface structure creation with NIL is based on mechanical deformation of the patterning material. This is radically different from the two main established methods, ultra violet lithography (UVL) and elect

The European project has come a long way in establishing peace, creating a common market, and expanding its borders. At the same time, diminishing popular legitimacy has spurred talk about a European Union in crisis. How far has the EU really come in fulfilling its grand visions? Is the project barely half-way? Or could we say with some confidence that European integration is solidified and will c

Although trisomy 8 as a sole change is one of the most common chromosomal abnormalities in myeloid malignancies, it is largely unknown if the incidence of this aberration is influenced by other factors of clinical importance. In the present study, the frequencies of isolated +8 in relation to gender, age, previous treatment with chemo- or radiotherapy, and morphologic subtype were ascertained in p

Objectives. To evaluate long-term changes in acetylcholinesterase (AChE) activity in CSF and blood following donepezil treatment in relation to the concentration of donepezil and cognition in AD patients. Methods. CSF or blood (or both) samples of a total of 104 patients with mild AD were used [MMSE score 23 +/- 0.4; age 75 +/- 1 years (mean +/- SEM); n = 53 for CSF and n = 51 for plasma/red blood

This study analysed the costs of median and ulnar nerve injuries in the forearm in humans and factors affecting such costs. The costs within the health-care sector and costs of lost production were calculated in 69 patients with an injury to the median and/or ulnar nerve in the forearm, usually caused by glass, a knife, or a razorblade. Factors associated with the variation in costs and outcome we

There is an increasing use of distributed computer systems to provide services in both traditional telephony as well as in the Internet. Two main technologies are Distributed Object Computing (DOC) and Web based services. One common DOC architecture investigated in this thesis is the Common Object Request Broker Architecture (CORBA), specified by the Object Management Group. CORBA applications con

Many tissues exhibit metabolic compartmentation. In the brain, while there is no doubt on the importance of functional compartmentation between neurons and glial cells, there is still debate on the specific regulation of pathways of energy metabolism at different activity levels. Using (13)C magnetic resonance spectroscopy (MRS) in vivo, we determined fluxes of energy metabolism in the rat cortex

Deuterated proteins and other bio-derived molecules are important for NMR spectroscopy, neutron reflectometry, small angle neutron scattering, and neutron protein crystallography. In the current study we optimized expression media and cell culture conditions to produce high levels of 3 different deuterated human carbonic anhydrases (hCAs). The labeled hCAs were then characterized and tested for de

The temperature in the thermal boundary layer close to the combustion chamber wall was measured under knocking and non-knocking conditions using dual-broadband rotational coherent anti-Stokes Raman Scattering (CARS). A horseshoe-shaped combustion extension was employed to get an optical access to the region near the combustion chamber wall. Time-resolved measurements of the cylinder pressure (at t

Sporulation in Ashbya gossypii is induced by nutrient-limited conditions and leads to the formation of haploid spores. Using RNA-seq, we have determined a gene set induced upon sporulation, which bears considerable overlap with that of Saccharomyces cerevisiae but also contains A. gossypii-specific genes. Addition of cyclic AMP (cAMP) to nutrient-limited media blocks sporulation and represses the

Increased growth in early childhood has been suggested to increase the risk of type 1 diabetes. This study explored the relationship between weight or height and development of persistent islet autoimmunity and progression to type 1 diabetes during the first 4 years of life in 7,468 children at genetic risk for type 1 diabetes followed in Finland, Germany, Sweden, and the U.S. Growth data collecte
