A mixed amphiphilic system composed of the anionic surfactant Aerosol OT (AOT), in water forming a lamellar phase, to which is added a neutral noninteracting polymer, poly(N,N-dimethylacrylamide), is studied experimentally by SAXS, H-2 NMR, and microscopy, in a range of surfactant and polymer compositions. Addition of the polymer produces a decrease in the lamellar spacing, the decrease by the pol
The distribution of sediment-dispersed extraterrestrial (ordinary chondritic) chromite (EC) grains (>63 pm) has been studied across the latest Maastrichtian and Paleocene in the Bottaccione Gorge section at Gubbio, Italy. This section is ideal for determining the accumulation rate of EC because of its condensed nature and well-constrained sedimentation rates. In a total of 210 kg of limestone repr
The purpose of this thesis is to investigate the Swedish stock market’s reaction of asset sale announcements and to see how the stated use of proceeds impacts the announcement effect. To fulfill the purpose the following research questions are asked: Is there an announcement effect associated with asset sales in general? Is the announcement effect, if any, dependent on the stated use of proceeds?
Europarådets ramkonvention om skydd för nationella minoriteter, FCNM, utgör världens första juridiskt bindande multilaterala instrument till skydd för nationella minoriteter. FCNM stadgar olika typer av principer till skydd för nationella minoriteter och det åläggs konventionsstaterna till FCNM att förverkliga dessa principer genom sin nationella lagstiftning och politik. Forskningsfrågan för dettThe Council of Europe’s Framework Convention for the Protection of National Minorities, the FCNM, is the world’s first legally binding multilateral instrument devoted to the protection of national minorities. The FCNM sets out a variety of principles on the protection of national minorities. These principles are to be implemented through national legislation and governmental policies of the states
Political narratives and nationalist myths often promote specific images of women and men, of masculinity and femininity. Historically, such discourse has been used to promote gendered traits and norms, positioning, for example, women as the biological and cultural reproducers of the state, and men as its defenders. Within this discourse, rural men are often portrayed as the embodiments of a tradi
This study examines how The New York Times and The Guardian framed the Mahsa Amini protests in Iran from September 2022 to September 2023. Using qualitative content analysis of 186 news articles, guided by framing theory and the protest paradigm, the study explores dominant frames, predominant themes, narratives, and depictions of protest legality and state responses. A mixed inductive-deductive c
Prior to the adoption of Article 17 of the Directive (EU) 2019/790 on Copyright and Related Rights in the Digital Single Market, the e-Commerce Directive provided hosting liability exemptions for intermediary service providers. In addition, copyright exceptions and limitations were previously optional and their implementation was at liberty of the Member States. Under the new Article 17 Member Sta
Introduction: Using time-limited trials of low-dose, sustained-release morphine to reduce chronic breathlessness to evaluate net effects may generate opioid withdrawal symptoms if medication is ceased. This sub-study of a larger randomized, placebo-controlled, double-blind trial aimed to evaluate if this occurred. Methods: People with modified Medical Research Council breathlessness scores of 3 or
BackgroundThe Job Demand–Control–Support (JD-C-S) model evaluates how psychosocial work factors affect health and performance. We examined how demographics, job title, and experience influence demand, control, and support among Ghanaian pharmacy staff.MethodsA cross-sectional survey of pharmacy personnel from Tamale and Sagnerigu was conducted using the JD-C-S questionnaire. Demand and control ite
BACKGROUND AND OBJECTIVE: Although the effects of 5-α-reductase inhibitors (5-ARIs) on prostate-specific antigen (PSA) have been well-studied, the effects on other kallikrein markers have not been firmly established. Accordingly, a statistical model based on blood measurements of four kallikreins-known commercially as the "4Kscore"-cannot be used for men taking 5-ARIs. We investigated how finaster
BACKGROUND/AIM: Determining the causation of an injury in living individuals is a key task for forensic pathologists. However, little is known about sex-based differences in injury characteristics. The study aims to examine sex-based differences in single stab injuries to the trunk among assault survivors, to potentially identify injury patterns that could aid forensic assessment and help in the m
Mobile commerce, or m-commerce, is an idea that involves different applications, new technologies and services which are accessible from Internet-enabled Mobile devices. In our study we compare existing 3G mobile services in two countries: Sweden and Japan. Furthermore, we investigate why these services are at the different stages of the development. In addition, we examine what may be the obstacl
When initiating the research for my graduate paper I had a rather straightforward intent in mind. It was to determine if the research being conducted in the bio-health related field was negatively affected by the patent system. If the research was delayed by the patent system I wanted to apprehend why. I came to the conclusion that over the years the sphere where the exchange of intellectual prope
Primary open angle glaucoma (POAG) is a major blindness-causing disease, characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork (TM) lining the aqueous outflow pathway modulates the aqueous outflow facility. TM cell adhesion, cell-matrix interactions, and factors that influence Rho signaling in TM cells are thought to play a pivotal
Objective. To assess the efficacy of low-dose prednisolone on joint damage and disease activity in patients with early rheumatoid arthritis (RA). Methods. At the start of their initial treatment with a disease-modifying antirheumatic drug (DMARD), patients with early (duration <= 1 year) active RA were randomly assigned to receive either 7.5 mg/day prednisolone or no prednisolone for 2 years. Radi
Gait Speed Reserve (GSR) expresses a difference between fast and comfortable gait speed and may have an impact on everyday functioning. It was also hypothesized as a useful proxy measure of physiological reserve. However, height-normalizing values of GSR and its associated factors have not been evaluated in a general population of older adults. Therefore, we aimed to investigate the distribution o
Background: Acquired loss of the largest von Willebrand factor multimers is a common hemostatic disturbance in patients with aortic valve stenosis (AS), resulting in impaired platelet adhesion and increased bleeding risk. AS is also associated with atherosclerosis and myocardial infarction (MI). Our aim was to study the clinical outcomes associated with AS in MI patients treated with dual antiplat
