The change in structure and mobility of poly(ethylene oxide) (PEO) containing 2 wt% of fumed silica and the water self-diffusion coefficient in concentrated PEO-water systems have been investigated at room temperature in the water weight fraction, w(w) range 0-0.50 w/w. Pulsed field gradient nuclear magnetic resonance was used to measure the self-diffusion coefficients. Structure and mobility prop
The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics. The thesis include the construction and evaluation of different variable selection te
Proteins and peptides in bovine milk and colostrum were separated by two-dimensional gel electrophoresis (2-DE). The proteins were separated in the first dimension by isoelectric focusing in the pH ranges 4-7 and 6-11, and in the second dimension by sodium dodecyl sulphate polyacrylamide gel electrophoresis on 12.5% T homogeneous gels. The peptides were separated in the pH range 3-10 in the first
The aim was to develop a new instrument for measuring length of sleep as well as television and computer habits in school-age children. A questionnaire was constructed for use when children visit the school health care unit. Three aspects of the validity of the questionnaire were examined: its face validity, content validity, and construct validity. Test-retest reliability was assessed by giving t
Indonesia has experienced rapid land use change over the last few decades as forests and peatswamps have been cleared for more intensively managed land uses, including oil palm and timber plantations. Fires are the predominant method of clearing and managing land for more intensive uses, and the related emissions affect public health by contributing to regional particulate matter and ozone concent
An economically sustainable process was developed for propionic acid production by fermentation of glycerol using Propionibacterium acidipropionici and potato juice, a by-product of starch processing, as a nitrogen/vitamin source. The fermentation was done as high-cell-density sequential batches with cell recycle. Propionic acid production and glycerol consumption rates were dependent on initial b
The harmful effects of cyanotoxins in surface waters have led to increasing demands for accurate early warning methods. This study proposes a capacitive immunosensor for broad-spectrum detection of the group of toxic cyclic peptides called microcystins (∼80 congeners) at very low concentration levels. The novel analytical platform offers significant advances compared to the existing methods. Monoc
We argue that the current system of agri-environment management in the European Common Agricultural Policy is ineffective at conserving biodiversity in part because it promotes fragmentation instead of collaboration of actors, thus hindering coordinated biodiversity management. Actor fragmentation is reinforced by the Common Agricultural Policy (CAP) in three ways: (1) through targeting individual
Photosystem I (PSI) is combined with Desulfovibrio gigas hydrogenase for the bioelectrocatalytic photosynthesis of hydrogen at an electrode surface. The activity of these two biocatalysts is linked by two redox polymers; a redox polymer with a relatively positive potential (loaded with an Os complex) is able to reduce PSI and thus facilitates the production of photoexcited electrons, whereas redox
The general rule in EC law is that a holder of an intellectual property right is not obliged to license the use of that right to others. However, situations exist where intellectual property rights suffer some limitations because of the prevalence of other conflicting interests. A dominant firm can, as the holder of an intellectual property right, be forced to grant a license to one or more undert
Syftet med denna uppsats är att utreda det straffrättsliga skyddet mot hedersrelaterat våld och förtryck mot kvinnor, samt studera hur strukturella ojämlikheter påverkar kvinnors möjligheter till skydd mot denna typ av våld i Sverige. För att uppnå detta syfte behandlas frågor som exempelvis vad hedersrelaterat våld och förtryck är, hur den svenska lagstiftningen på området ser ut samt hur lagstifThe purpose of this thesis is to examine whether the Swedish criminal justice system gives women adequate protection against honor related violence and oppression. The thesis also examines how structural inequalities effects the protection provided by the system. To achieve this, the thesis defines what honor related violence and oppression is, examines how the applicable Swedish law is designed a
Unilateral coercive measures are a foreign policy tool that are thousands of years old and used by states in response to foreign policy concerns. Their use has become more common throughout the 21st Century, and this raises concerns from a human rights perspective. The purpose of this thesis is to demonstrate that unilateral coercive measures exacerbate suffering and add additional human rights vi
Plant-insect interactions play a crucial role in the evolution of the coevolving web of life, shaping local interaction networks and moulding the diversity and the evolutionary history of two of the most diverse groups of organisms on earth. The interaction between Lithophragma bolanderi (Saxifragaceae), which presents a geographic mosaic of ploidy levels, and the pollinating floral parasite Greya
In a study of the reaction e(-)e(+)-> W-W+ with the DELPHI detector, the probabilities of the two W particles occurring in the joint polarisation states transverse-transverse (T T), longitudinal-transverse plus transverse-longitudinal (LT) and longitudinal-longitudinal (LL) have been determined using the final states WW -> lvq (q) over bar (l = e, mu). The two-particle joint polarisation probabili
Popular Abstract in Swedish Introduktion: Validitet handlar enkelt uttryckt om överensstämmelse med sanningen eller exempelvis om ett instrument mäter det som är avsett. Validitet kan också ses som ett mer komplext begrepp, innefattande aspekter som nytta, relevans, värderingar och sociala konsekvenser. Validitet förutsätter reliabilitet som är ett mått på tillförlitlighet, noggrannhet eller reproAbstract Introduction: Validity is important at different levels in psychiatry. Valid structured instruments are important aids in screening and diagnostics, in both research and clinical practice. An aim of the diagnostic procedure is to yield valid diagnoses. Ultimately, the validity of structured instruments (non-empirical) and clinical diagnoses depends on the validity of the diagnostic class
The transport behavior of lambda-DNA (48 kbp) in fused silica nanoslits is investigated upon application of electrical fields of different strengths. The slit dimensions are 20 nm in height, 3 microm in width, and 500 microm in length. With fields of 30 kV/m or below, the molecules move fluently through the slits, while at higher electrical fields, the DNA molecules move intermittently, resulting
The purpose of this paper is to contribute to the existing research within the subject of the Magic Formula. The investment strategy will be tested on historical data for companies on the Stockholm stock exchange during the period 2007-04-01 to 2017-03-31. The return will be benchmarked against OMXS30 as an indicator of the market return. In addition to comparisons between the return of the Magic
Life at a music festival can be both a blessing and a curse. It creates a feeling of escaping reality into euphoric happiness and freedom that only music festivals can bring. But one thing can drastically change this mood and make the living at the festival quite miserable – the weather. Rain as well as too high or low temperatures contribute to this negative change of mood. The festival chosen fo
In recent years, Iceland has experienced a growing demand for residential housing and the average square-meter price for apartments and single-family homes in the Capital Region has almost doubled between 2010 and 2019. Property sales in Iceland are most commonly intermediated by real estate brokers and the sales process stands in contrast to other Nordic countries, since it involves a bidding pro
