The thermotropic phase behaviour and phase structure of crystalline and non-crystalline n-tetradecyl-beta-D-maltoside (C(14)G(2)) and n-hexadecyl-beta-D-maltoside (C(16)G(2)) have been investigated by means of differential scanning calorimetry and X-ray techniques. Upon lyophilisation, both compounds form a solid, lamellar phase comprising disordered head groups and hexagonally packed alkyl chains
Recent experimental results by the surface force apparatus (SFA) have identified a dramatic deviation from previously established theories of simple electrolytes. This deviation, referred to as anomalous underscreening, suggests that the range of electrostatic interactions increase upon a further addition of salt, beyond some threshold concentration (usually about 1 M). In this theoretical work, w
I begin my thesis by linking the rise of buzz marketing in recent years to general economic, medial and social developments in society, while mainly focusing on the shift from a modern to a post-modern pattern of production and consumption. I also point out the great symbolic significance that consumption has as a signifier of a personal identity in contemporary society. I then go on to investigat
This paper presents a pilot study investigating the development of declarative memory in infancy, by creating a stimulus material appropriate for recording Event-Related Potentials (ERPs) during memory encoding. The material was designed to establish associations between pictures, and a negative component with a fronto-central distribution (Nc) was studied as a reflection of learning. In addition
This study compares the acoustic realisation of /iː yː ʉː uː/ inthree varieties of Swedish: Central Swedish, Estonian Swedish, and Finland Swedish. Vowel tokens were extracted from isolated words produced by six elderly female speakers from each variety. Trajectories of the first three formants were modelled with discrete cosine transform (DCT) coefficients, enabling the comparison of the formant This study compares the acoustic realisation of /i: y: ʉ: u:/ in three varieties of Swedish: Central Swedish, Estonian Swedish, and Finland Swedish.

In quality assurance programs, we want indicators of software quality, especially software correctness. The number of found defects during inspection and testing are often used as the basis for indicators of software correctness. However, there is a paradox in this approach, since the remaining defects is what impacts negatively on software correctness, not the found ones. In order to investigate
We study a system of spherical non-adsorbing particles immersed in a polydisperse polymer fluid. We derive an analytic expression for the many-body depletion interactions between the colloidal particles in the limit of very long chains. We argue that this expression is essentially exact for long chains and justify this using explicit simulations. In this way we are able to elucidate the profound e
This study examines fuel use and metabolism in a group of long-distance migrating birds, red knots Calidris canutus (Scolopacidae), flying under controlled conditions in a wind tunnel for up to 10 h. Data are compared with values for resting birds fasting for the same time. Plasma levels of free fatty acids, glycerol and uric acid were elevated during flight, irrespective of flight duration (1-10h
Background: In recent years, analyses of cleft palate speech based on phonetic transcriptions have become common. However, the results vary considerably among different studies. It cannot be excluded that differences in assessment methodology, including the recording medium, influence the results. Aims: To compare phonetic transcriptions from audio and audio/video recordings of cleft palate speech
Insertion of interfacial molecules in bulk heterojunction and dye sensitized solar cells is effective to retard charge recombination reactions and thus to improve solar cell performance. So far, to extend charge separated state lifetime, the molecule was designed to increase distance between an n-type and a p-type semiconductors to reduce their electronic coupling. Here we investigated a series of
In order to achieve a consistent level of failure probability, structural design codes are optimized using probabilistic methods. This optimization process traditionally focuses on the ultimate limit states (ULS). However, in the design of timber structures the performance of the structural members is often governed by the serviceability limit state (SLS) associated with different load levels than
The present study numerically investigates the second law analysis of turbulent flow in novel outward helical corrugated tubes by using a Reynolds Stress Model (RSM). A case of a transverse corrugated tube and five cases of helical corrugated tubes with different height-to-diameter ratios and pitch-to-diameter ratios are examined with Reynolds number ranging from 3800 to 43,800 at a constant wall
This study begins in the understanding of sustainable development as a complex matter open for interpretation, and continues in the notion that different dimensions of sustainability create different values that have different goals; meaning that they will sometimes unite, and sometimes collide and lead to trade-offs. The aim for this study is to add to the understanding of this matter through an
Academia is vertically gender segregated, where women are underrepresented in senior positions in all fields (Allbright, 2019; Curtis, 2011; European Commission, 2016; Swedish Higher Education Authority (UKÄ), 2017). This study investigated research self-efficacy and social belongingness expectations as social cognitive mediators of research career interest in a sample of 239 Swedish social scienc
Poor menstrual health (MH) harms women in various ways globally, and therefore maintaining sufficient MH is vital. However, MH is not considered as a Human Right and is generally unprioritized, especially in resource poor areas. There is a prominent research gap on MH and in particular among women in different ages in rural areas. This study therefore aims to investigate the MH among mothers, in v
Purpose: The purpose of this study is to test how Nordic acquirers perform post M&A deals and to what extent the Method of Payment affects this performance. An additional analysis is also conducted where the above is tested, conditional on the financial constraints of the acquirer. Methodology: To obtain the long-term performance (BHAR) of Nordic acquirers, an event study has been conducted.
Background: Early developmental conditions can influence within- and among-brood variation in the timing of hatching/birth, which has been shown to affect offspring survival, growth, and reproductive success across a range of species. Problem: How does within- and among-litter variation in the timing of birth affect offspring growth and survival in Egernia whitii? Organism: Egernia whitii, a l
The purpose of this study was to explore neuroretinal transplantation in a large animal model of severe retinitis pigmentosa and to establish graft development, long-term survival, graft-host integration, and effects on the host retina. Methods Rhodopsin transgenic pigs, aged 6 months, received in one eye a fetal full-thickness neuroretinal sheet in the subretinal space by means of vitrectomy and
The paper is supposed to form part of an anthology on diversification processes in South-East Asian agriculture. This particular paper looks at farmers that have left agriculture, in particular their reasons for leaving agriculture. The paper also includes an explicit gender dimension as part of the investigation focuses on factors that would particulary affect women in their agricultural roles.
