Polysulfones functionalized with highly phosphonated poly(pentafluorostyrene) side chains of different length were synthesized applying controlled polymerization and modification methods. The graft copolymers' thermal properties were evaluated by differential scanning calorimetry and thermal gravimetrical analyses. The proton conductivity of membrane prepared from the graft copolymer with the shor
Popular Abstract in Swedish Vid förbränning av bränslen som innehåller kol, till exempel ved, olja och biobränslen, bildas sotpartiklar då det finns ett underskott av syre, så kallad ofullständig förbränning. Det är sotpartiklarna i brasan som ger dess gula sken. Dessa partiklar är små och består till största delen av oförbränt kol från bränslet. De små sotpartiklarna är hälsofarliga då de följer In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtai
Background: Improving maternal and reproductive health still remains a major challenge in most low-income countries especially in sub-Saharan Africa. The growing inequality in access to maternal health interventions is an issue of great concern. In Ghana, inadequate attention has been given to the inequality gap that exists amongst women when accessing antenatal care during pregnancy and skilled a
Background- This nationwide study sought to determine age- and gender-specific familial risks in siblings hospitalized for venous thromboembolism (VTE). Methods and Results- The Swedish Multigeneration Register on 0- to 75-year-old subjects was linked to the Hospital Discharge Register for the years 1987-2007. Standardized incidence ratios were calculated for individuals whose siblings were hospit
The sub-cell-fix (SCF) method proposed by Russo and Smereka(3) computes the distance function of the cells adjacent to the zero level-set without disturbing the original zero level-set. A modified sub-cell-fix scheme independent of local curvature is developed in this paper, which makes use of a combination of the points adjacent to zero level-set surfaces and preserves the interface in a second-o
Small arteries are known to develop functional and structural alterations in hypertension. However, the mechanisms of this remodeling are not fully understood. We hypothesized that altered gene expression is associated with the development of hypertension in mesenteric arteries of spontaneously hypertensive rats (SHR). Three sublines of SHR and normotensive Wistar Kyoto rats (WKY) were studied at
This paper presents a structured methodology for the constrained multi-objective optimization (MO) of a continuous cross-flow atomic layer deposition (ALD) reactor model with temporal precursor pulsing. The process model has been elaborated and experimentally validated in the first two papers of this series (33 and 34). A general constrained MO problem (MOP) was formulated to simultaneously optimi
Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. This report concerns the Dissipating Energy Flow (DEF), which is an energy-based method for analysing dampi
The purpose of this thesis was to explore how a newly founded Youth Platform in Colombia, called La Mesa de Juventud, could affect the youth community in promoting and capacitating organizational skills, youth citizenship rights and youth influence in public policy making. The study emanates from the region of northern Cauca situated in the South Western part of Colombia which is an area where you
The aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. In 30 of the jars 0 to 15 g fish oil were added and in the other 30 jars 0 to 21 g AkoFeed were added. 2/
Simulating the natural environment of living tissue with in vitro cell culture models has paved the way for scientific discoveries, and provided valuable insight into areas such as drug discovery and regenerative medicine. A new emerging technique of culturing cells on biomimetic three-dimensional scaffolds stands as a promising alternative to the traditional way of culturing cells on two-dimensio
The primary purpose of this paper is to further build on research related to capability development in order to explore hindrances and benefits of internal capability development and external partnerships as ways to improve performance. The beverage industry is used as the focus context since the companies in this industry are increasingly responding to external trends and looking for ways to deve
With the 11th century text Kitāb ādāb al-nikāḥ, the “Book on the Proper Conduct of Marriage”, the Islamic thinker al-Ghazālī (1056 –1111/447–504) replies to a contemporaneous debate within Sufi asceticism with a theology of nikāḥ. The text is part of his opus magnum, the “Renaissance of the Knowledge of dīn”, which aims at a renewal of Muslim piety and provides practical guidance to the male audie
Anthropogenic climate change and environmental degradation demand humanity to depart from the growth imperative forming the economic structure of the world. In other words: Structural transformation is needed. Much of the sustainability debate in academy, politics, media and the public revolves around two paradigms: minor changes within the current system (e.g. green consumption, green growth) or
Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced. A well-controlled dynamic solvent vapor annealing chamber is built, and the best annealing co
Background: The aim of this study was to evaluate the test-retest reliability and the validity of the self-reported questionnaire Olerud-Molander Ankle Score (OMAS) in subjects after an ankle fracture. Methods: When evaluating the test-retest reliability of the OMAS, 42 subjects surgically treated due to an ankle fracture participated 12 months after injury. OMAS was completed by the patients on t
The electronic structure of strongly correlated systems is usually calculated by using an effective model Hamiltonian with a small number of states and an effective on-site interaction. The mode, however, neglects the frequency dependence of the interaction, which emerges as a result of dynamical screening processes not included in the model. The self-energy calculated in this kind of model within
Background: Women working in the public human service sector in 'overstrained' situations run the risk of musculoskeletal symptoms and long-term sick leave. In order to maintain the level of health and work ability and strengthen the potential resources for health, it is important that employees gain greater control over decisions and actions affecting their health - a process associated with the
