Sprickbildning i puts på isolering : undersökning av grundläggande mekanismer - del 4

SAMMANFATTNING För att förstå inverkan av olika putsbruk, utförande och härdning på deformationer hos armerad puts utsattes putsremsor för uttorkning och upp fuktning under kontrollerade förhållanden. Putsremsornas deformationer, d.v.s. den axiella deformationen samt deformationer vinkelräta mot putsremsans längdaxel, bestämdes under pågående upp fuktning och uttorkning. Provningarna utfördes med

Unraveling Charge Carriers Generation, Diffusion, and Recombination in Formamidinium Lead Triiodide Perovskite Polycrystalline Thin Film.

We report on studies of the formamidinium lead triiodide (FAPbI3) perovskite film using time-resolved terahertz (THz) spectroscopy (TRTS) and flash photolysis to explore charge carriers generation, migration, and recombination. The TRTS results show that upon femtosecond excitation above the absorption edge, the initial high photoconductivity (∼75 cm(2) V(-1) s(-1)) remains constant at least up to

Towards Efficient Quantum Memories in Rare-Earth-Ion-Doped Solids

This thesis describes experiments aimed at developing a key component in applications such as quantum networks and long-distance quantum communication systems: quantum memories. Quantum memories for light using photon-echo and coherent rephrasing techniques have been developed. The work is carried out on rare-earth-ion-doped inorganic crystals. Several properties are associated with these crystals

Implementing a continuum of care model for older people-results from a Swedish case study.

There is a need for integrated care and smooth collaboration between care-providing organisations and professions to create a continuum of care for frail older people. However, collaboration between organisations and professions is often problematic. The aim of this study was to examine the process of implementing a new continuum of care model in a complex organisational context, and illuminate so

Simvastatin Reduces Endotoxin-Induced Acute Lung Injury by Decreasing Neutrophil Recruitment and Radical Formation

Introduction: Treatment of acute lung injury (ALI) remains an unsolved problem in intensive care medicine. As simvastatin exerts protective effects in inflammatory diseases we explored its effects on development of ALI and due to the importance of neutrophils in ALI also on neutrophil effector functions. Methods: C57Bl/6 mice were exposed to aerosolized LPS (500 mg/ml) for 30 min. The count of alv

Heavy flavour decay muon production at forward rapidity in proton-proton collisions at root s=7 TeV

The production of muons from heavy flavour decays is measured at forward rapidity in proton-proton collisions at root s = 7 TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity L-int = 16.5 nb(-1). The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are m

Influence of Insulin-Like Growth Factor Binding Protein (IGFBP)-1 and IGFBP-3 on Bone Health: Results from the European Male Ageing Study

The aim of this study was to determine the influence of insulin-like growth factor binding protein (IGFBP)-1, IGFBP-3, and IGF-I on calcaneal ultrasound parameters in middle-aged and elderly European men. Men aged 40-79 years were recruited from population registers for participation in the European Male Ageing Study (EMAS). Subjects were invited by letter to complete a postal questionnaire and to

A Brief Introduction to PYTHIA 8.1

Abstract in UndeterminedThe PYTHIA program is a standard tool for the generation of high-energy collisions, comprising a coherent set of physics models for the evolution from a few-body hard process to a complex multihadronic final state. It contains a library of hard processes and models for initial-and final-state parton showers, multiple parton-parton interactions, beam remnants, string fragmen

Muscle function and physical activity in pre-pubertal school children

Popular Abstract in Swedish Bakgrund: Regelbunden fysisk aktivitet och träning anses som en livsstilsfaktor som kan förbättra muskelstyrkan, skelettet, konditionen och kroppssammansättningen. För barn och ungdomar är fysisk aktivitet inte bara viktigt för att träna de muskulära funktionerna, koordinationen och balansen. I ett större perspektiv kan en fysiskt aktiv livsstil också minska risken för Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly r

Differential Roles of Fibroblast Growth Factor Receptors (FGFR) 1, 2 and 3 in the Regulation of S115 Breast Cancer Cell Growth

Fibroblast growth factors (FGFs) regulate the growth and progression of breast cancer. FGF signaling is transduced through FGF receptors 1-4, which have oncogenic or anti-oncogenic roles depending on the ligand and the cellular context. Our aim was to clarify the roles of FGFR1-3 in breast cancer cell growth in vitro and in vivo. Pools of S115 mouse breast cancer cells expressing shRNA against FGF

Oxy-fuel Combustion of Ethanol in Premixed Flames

First measurements of the adiabatic laminar burning velocities of lean ethanol + oxygen + carbon dioxide flames, at 1 atm and initial gas mixture temperatures of 298, 318, and 338 K, are presented. The oxygen content O-2/(O-2 + CO2) in the artificial air was 35%. The laminar burning velocities were determined using the heat flux method, where a non-stretched flame is stabilized under adiabatic con

Catenarina (Teloschistaceae, Ascomycota), a new Southern Hemisphere genus with 7-chlorocatenarin

A new genus, Catenarina (Teloschistaceae, Ascomycota), with three species is described from the Southern Hemisphere, supported by molecular data. All species contain the secondary metabolite 7-chlorocatenarin, previously unknown in lichens. Catenarinadesolata is a non-littoral, lichenicolous species found on volcanic and soft sedimentary rock at 190-300 m in and near steppes in southernmost Chile

Analytical prediction of package collapse - consideration of windows in the package

Windows in a package is a common way to promote the product. The possibility to predict the collapse load for these types of cartonboard packages is considered. It is shown that reliable estimates of the collapse loads can be obtained by a very simple approach. This approach is a straightforward generalization of the proposal by Ristinmaa et al. (2012): for a side that contains a window, one simpl

Nonadaptive radiation in damselflies

Adaptive radiations have long served as living libraries to study the build-up of species richness; however, they do not provide good models for radiations that exhibit negligible adaptive disparity. Here, we review work on damselflies to argue that nonadaptive mechanisms were predominant in the radiation of this group and have driven species divergence through sexual selection arising from male-f

A longitudinal study of sexual functioning in women referred for colposcopy: a 2-year follow up.

Objective To elucidate psychosexual problems in women referred for colposcopy after an abnormal cervical smear and a 6-month and 2-year follow up. Design Prospective study. Setting Department of Gynaecology, Malmö University Hospital, Sweden. Population One hundred consecutive women referred for colposcopy for the first time subsequent to receiving notification of an abnormal cervical smear. M
