A combination of NMR chemical shift imaging and self-diffusion experiments is shown to give a detailed molecular picture of the events that occur when tablets of hydrophobically modified poly(acrylic acid) loaded with a drug (griseofulvin) swell in water in the presence or absence of surfactant (sodium octylbenzenesulfonate). The hydrophobic substituents on the polymer bind and trap the surfactant

Charge generation and recombination are studied in blend films of poly-3-hexylthiophene (P3HT) and [6,6']phenyl C61 butyric acid methyl ester (PCBM) using ultrafast transient absorption spectroscopy. We find that the charge generation yield depends upon both blend film composition and thermal annealing. The data suggest that recombination occurs over a wide range of time scales and that, in the le

The interaction of water vapor with ice remains incompletely understood despite its importance in environmental processes. A particular concern is the probability for water accommodation on the ice surface, for which results from earlier studies vary by more than 2 orders of magnitude. Here, we apply an environmental molecular beam method to directly determine water accommodation and desorption ki

The energy level structure and dynamics of biomolecules are important for understanding their photoinduced function. In particular, the role of carotenoids in light-harvesting is heavily studied, yet not fully understood. The conventional approach to investigate these processes involves analysis of the third-order optical polarization in one spectral dimension. Here, we record two-dimensional corr

This article analyses the consequences of using the concept of caregiving as a basis of extending social rights in the welfare state. By focusing on the administration of the right to a care allowance to a parent with a disabled child, the development of the concept of individualized justice and the use of discretion are examined. The article reveals how rights are differentially distributed throu

Hur vi väljer att organisera våra familjer har genomgått en radikal förändring sedan mitten av 1900-talet. Kärnfamiljen är visserligen fortfarande den vanligaste familjeformen, men den har i allt större utsträckning kommit att kompletteras med en rad icke-traditionella familje-konstellationer, bl.a. samkönade familjer. Den här utvecklingen har naturligtvis också påverkat hur vi lever och praktisHow we choose to organize our families has changed significantly since the mid-20th century. It might be true that the nuclear family remains the most common family form. However, it has to an increasing extent been accompanied by a number of non-traditional families, including same-sex families. Naturally, this development has also affected the way we live and how we practice family life. While

COURSE: BUSN29: Master Degree Project AUTHORS: Orkun Eti, Lysbet Doutzen de Boer SUPERVISOR: Mr. J. Bertilsson THESIS PURPOSE: The purpose of the study is to investigate how passionate consumers experience their brand relationship. With help of the photo elicitation technique we aim to evoke feelings, stories, and memories in order to provide a new perspective on the theory of brand love.

Challenger branding is a phenomenon that is gaining significant exposure in academia. However, most research on this branding approach relates to a practical or technical knowledge interest, ignoring the counter-hegemonic critique that exemplifies challenger branding. The critique that these brands base their identity on often shifts after they have been acquired into a hegemonic context, by joini

Virtual communities, including communities dedicated to consumption practices, were named one of the rising modern trends. With the technological development, nowadays, people do not need actual locations to meet for being friends because multiple blooming social networks allow people to stay connected 24/7 no matter where they are in this world. This technological development has many positive ef

This report considers improvements in Swedish Rescue Service Agency’s obser- vation activity on occurred accidents. A model is constructed to develop the work for observers and decisions-makers.

Large gulls are generalist predators that play an important role in Arctic food webs. Describing the migratory patterns and phenology of these predators is essential to understanding how Arctic ecosystems function. However, from all six large Arctic gull taxa, including three long-distance migrants, to date seasonal movements have been studied only in three and with small sample sizes. To document

This study develops a theory for the formation of Radical Right Populist (RRP) identities based on the theory of Social Constructivism. The identity construction theory thus proposes that three components must exist in order for RRP identities to be formed. Here, RRP identities are formed during the simultaneous actions of a top ? down and a bottom ? up process of identity formation, and once a RR

Using near-infrared femtosecond absorption spectroscopy, we have determined the S-1 energies of the carotenoids spheroidene and rhodopin glucoside in LH2 complexes of purple bacteria. The S-1 energies in the LH2 complexes yield values of 13400 +/- 100 cm(-1) for spheroidene and 12550 +/- 150 cm(-1) for rhodopin glucoside, which are very close to the S-1 energies obtained for both carotenoids in so

Rheumatoid arthritis (RA) is an autoimmune disease characterized by a persistent inflammation of the synovium, leading to the erosion of articular cartilage and bone. Synovial mast cells and their effector molecule, histamine, receive increased attention as mediators of joint inflammation. The aim of our study was to analyse levels of free histamine in serum and joint fluid of RA patients and to e

Bi-isonicotinic acid (2,2'-bipyridine-4,4'-dicarboxylic acid) is an important ligand in the chemistry of organometallic devices. Here, the adsorption of a monolayer of the molecule on in situ-grown anatase TiO2 nanoparticles has been investigated by means of X-ray photoemission spectroscopy and X-ray absorption spectroscopy. The bonding geometry is determined to be 2M-bidentate. Furthermore, reson

Objective: Fenestrated endovascular aneurysm repair (FEVAR) is a well established treatment for complex abdominal aortic aneurysms (AAAs). FEVAR with custom made devices (CMDs) has limitations in both the emergency and elective settings due to time consuming manufacture. “Off the shelf” (OTS) fenestrated stent grafts are a potential solution. The primary goal was to evaluate the five year outcome
