Interfacial electron transfer is one of the key processes in the novel type of photovoltaic cells-dye sensitized solar cells (DSSC). By means of transient absorption spectroscopy we have studied the dynamics of the initial photo-induced processes in dye-sensitized nano-porous thin films of wide-band gap semiconductor microcrystallines, which represent the main photoactive part of DSSC. In the most
Hyperplasia of the middle ear mucosa contributes to the sequelae of acute otitis media. Understanding the signal transduction pathways that mediate hyperplasia could lead to the development of new therapeutic interventions for this disease and its sequelae. Endotoxin derived from bacteria involved in middle ear infection can contribute to the hyperplastic response. The p38 mitogen-activated protei
The stars that populate the solar neighbourhood were formed in stellar clusters. Through N-body simulations of these clusters, we measure the rate of close encounters between stars. By monitoring the interaction histories of each star, we investigate the singleton fraction in the solar neighbourhood. A singleton is a star which formed as a single star, has never experienced any close encounters wi
The very bright red star HV2112 in the Small Magellanic Cloud could be a massive Thorne-A >> ytkow object (TA >> O), a supergiant-like star with a degenerate neutron core. With a luminosity of over 10(5) L-aS (TM), it could also be a super asymptotic giant branch (SAGB) star, a star with an oxygen/neon core supported by electron degeneracy and undergoing thermal pulses with third dredge up. Both T
We report experimental oscillator strengths for 88 Ti I transitions covering the wavelength range 465-3892 nm, 67 of which had no previous experimental values. Radiative lifetimes for 13 energy levels, including the low energy levels 3d(2)(F-3) 4s4p ((3)p) z(5)D(j)degrees have been measured using time-resolved laser-induced fluorescence. Intensity-calibrated Ti I spectra have been measured using F
We study the nature of the peculiar [Sr II] and Sr II emission filament found in the ejecta of Eta Carinae. To this purpose we carry out abinitio calculations of radiative transition probabilities and electron impact excitation rate coefficients for Sr II. Then we build a multilevel model for the system which is used to investigate the physical condition of the filament and the nature of the obser
Maternal effects by which females provide their offspring with non-genetic factors such as hormones, nutrients and antibodies can have an important impact on offspring fitness. In vertebrates, maternal antibodies (matAb) are transferred from the mother, via the placenta, egg yolk or milk during lactation to offspring until they are 2 weeks (birds), 4-10 weeks (rodents) and 9 months (humans) old, r
BACKGROUND. The clinical value of detecting prostate specific antigen (PSA) mRNA in the peripheral blood mononuclear cell fraction of patients (pts) by standard RT-PCR assays with localized prostate cancer remains controversial. We used a quantitative RT-PCR assay to measure the PSA mRNA copy number in addition to the qualitative PSA RT-PCR and correlated the results with clinical parameters. METH
Helicobacter pylori infection is associated with gastritis, ulcerations, and gastric adenocarcinoma. H. pylori secretes the vacuolating cytotoxin (VacA), a major pathogenicity factor. VacA has immunosuppressive effects, inhibiting interleukin-2 (IL-2) secretion by interference with the T cell receptor/IL-2 signaling pathway at the level of calcineurin, the Ca2+-calmodulin-dependent phosphatase. He
Diatom data of 192 surface sediment samples from the marginal seas in the western Pacific together with modern summer and winter sea surface temperature and salinity data were analyzed. The results of canonical correspondence analysis show that summer sea-surface salinity (SSS) is highly positively correlated with winter SSS and so is summer sea-surface temperature (SST) with winter SST. The corre
This thesis project challenges the current municipality plans for Trollhättan 4, 6 and 7 in Malmö and suggests an alternative vision for the place. Instead of working with high-density offices, residential buildings and retail, the project aims to work with a program such as spa and a bath with a distinct public character.
This study examines Turkey’s agricultural sector and how it will be affected by a EU membership. Since Turkey has a great rural population and is relatively dependent on its agriculture, the implementation of the CAP will most probably affect not only the rural community, but also the specialization patterns in agriculture and the trade. The aim of this study is to estimate these changes and draw
34_prog-skill-assess_mod LTHs 10:e Pedagogiska Inspirationskonferens, 6 december 2018 Abstract—I summarise the ideals and challenges of implementing an exam in introductory computer programming, and report on a successful implementation in 2018 at ITU.

Trade costs and sunk export costs play a crucial role in defining trade flows between countries and, directly, affect firms’ strategic decisions in terms of international expansion. Trade costs include all the costs attached to a delivery of good to a final user and, thus, incorporate transportation costs, policy barriers, information costs, contract costs and currency costs. Sunk costs include co
Mot bakgrund av USA:s viktiga roll i världspolitiken och speciellt i Mellanöstern och dess konflikter är uppsatsens syfte att undersöka USA:s flerfaldiga politik rörande Israel-Palestinakonflikten mellan 2000–2020. Syftet uppnås genom att besvara frågorna om hur USA har agerat i förhållande till konflikten mellan 2000–2020, vilka motiveringar USA har för sitt agerande samt hur USA:s politik kring Because of the important role that the United States plays in the politics of the world, especially in the Middle East conflicts, the purpose of this study is to analyze the U.S. multiple policy on the Israeli-Palestinian conflict between 2000-2020. The purpose of this study is achieved by answering the questions about how the U.S. has acted in relation to the conflict between 2000–2020, how the U
The study done in this thesis was based on a planned eco village in Röstånga, Sweden. The aim of the study was to find a solution into which energy- and ventilation systems that were sustainable and had the least environmental impact in combinations with each other and the chosen building materials. This has been done through literature studies, simulations and life cycle analysis based on those t
The climate is in a state of emergency. Anthropogenic climate change is destroying social and environmental systems across the world (albeit, unevenly) and jeopardizing the safety and humanity of present and future generations. Nevertheless, climate denialism persists as a rhetoric and belief, particularly within the burgeoning far-right political projects in countries most responsible for rising
Upphovsrätten präglas av flera svåra gränsdragningar varav denna uppsats fördjupar sig inom en av dessa. Svårigheten som behandlas i detta sammanhang består av problematiken att avgöra var gränsen går mellan ett skyddat verk och en oskyddad idé.

De två Natura-2000 områdena Ravlunda och Revingehed i Skåne, södra Sverige, har genomgått en klimatkänslighetsanalys i denna studie som testade en utvärderingsmetod för relevans att använda inom Länsstyrelsen i Skånes arbete. Analysen gjordes med fokus på ekosystemtjänster identifierad för sanddominerade habitat på de två områdena. Genom användning av en nyligen publicerad report från NaturvårdsveThe two Natura-2000 areas of Ravlunda and Revingehed of Skåne, southern Sweden, have been subject to a climate change vulnerability assessment in this study, which tested an assessment method for relevance for work within the County Administrative Board of Skåne. The analysis was done with focus on ecosystem services found at the sand dominated habitats of the two areas. Using a recently published
