Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced. A well-controlled dynamic solvent vapor annealing chamber is built, and the best annealing co

The interaction between starch and the whey proteins b-lactoglobulin and a-lactalbumin was examined in model systems. The change in thermal transitions (gelatinisation of starch, retrogradation of starch and melting of the amylose-lipid complex) on addition of various whey protein concentrations was studied with differential scanning calorimetry (DSC). The gelatinisation of starch was not influenc

The relationship between a percept-genetic measurement of creativity and other tests of creativity was investigated. The participants were elementary school children. The relation between self-image and three different creativity measures was also studied. A creative fluency test, a questionnaire about creative activities and a percept-genetic creativity test were used. A self-image inventory meas

Conventional methods often impose difficulties when measuring the viscosity of fluids containing particles or fibres, e.g. tomato paste or fruit preparations, mainly due to the narrow gaps of the viscometer. In order to solve these problems different geometries have been developed, e.g. different mixer systems and wide gap double concentric cylinders. However, these can not be evaluated assuming a

The formation of amylose-lipid complexes of form I (amorphous structure) and form II (crystalline structure) during heating was studied by differential scanning calorimetry (DSC) for a range of monoglycerides and for monoglyceride mixtures. The temperature treatment applied to amylose-monoglyceride-mixtures were either the first scan in DSC (10 °C/min, 15-144 °C) or a prolonged heat treatment wher

Twenty-four individuals, who were 16 years of age or younger when they sustained a fracture of the radial head or neck, were examined at a mean of 19 years (range 14-25 years) after injury. The 12 girls and 12 boys were a mean age of 11 years (range 5-16 years) when the fracture was sustained. Two were excluded due to late resection of the radial head following persisting pain. The fractures, whic

We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) project. We focused on characterizing the spatial and temporal variation of new particle formation events and relevant particle formation parameters across Europe. Dif

In a long-term prospective study, 39 preterm children born before 35 completed weeks of gestation and 23 full-term children were followed up at 19 years of age. Information about somatic and mental health was obtained through interviews and confirmed by medical records. Self-esteem and quality of life were assessed from the subjects' perspective. Significantly more preterms than full-terms had som

We report on an experimental and theoretical investigation of x-ray absorption and resonant Auger electron spectra of gas phase O(2) recorded in the vicinity of the O 1s-->sigma(*) excitation region. Our investigation shows that core excitation takes place in a region with multiple crossings of potential energy curves of the excited states. We find a complete breakdown of the diabatic picture for

Fourteen sites in 13 streams were surveyed to address the importance of food quality and quantity on trophic position, carbon signature, and growth rate of noble crayfish (Astacus astacus) by combining the analyses of gut content, stable isotopes, and RNA-DNA ratio. The gut content analysis showed an omnivorous feeding habit, but total animal food sources contributed more to the nitrogen and carbo

Background: Intranasal and oral antihistamines are effective in treating allergic rhinitis. Studies comparing these routes of administration of an antihistamine regarding efficacy and pharmacokinetic profile are lacking. Objective: To compare topical and oral routes of administration of cetirizine regarding efficacy, plasma exudation, and systemic drug levels in a repeated allergen challenge model

The microstructure of phase-segregated amylopectin (AP) and β-lactoglobulin (βlg) mixtures formed during drying from solutions with different concentrations and different polysaccharide and protein ratios have been studied using atomic force microscopy (AFM) and transmission electron microscopy (TEM). AFM was used as the main technique and TEM was used to confirm the results. Systems with only one

A method for the synthesis of novel fused tricyclic tetrazoles from allylic bromides generated by the recently discovered DiazAll reaction has been developed. This new tandem reaction comprises a cycloaddition between a nitrile and (TMS)N-3 followed by an intramolecular N-allylation. The variation of functionalities in the benzene moiety was well-tolerated, and only a moderate difference in yield

Tendon healing and integration of tendon grafts may be site or donor specific. To determine if differences exist in sensitivity to growth factors that have the potential to influence tendon repair, we compared the effect of recombinant human insulin-like growth factor-1 on various types of tendon segments. The dose response effects on proteoglycan, collagen, noncollagen protein, and DNA synthesis

How land-application of digestate sourced from anaerobic digestion (AD) of animal waste influences the functioning of a mixed pasture agroecosystem is not well characterised, particularly with regard to the response of the actively growing microbial community. We studied the impact of the liquid AD digestate on the decomposer community in two different soils, seeded with two different common grass
