I välgörande syfte : En explorativ studie av välgörenhetsorganisationers marknadsföringsstrategier i relation till donatorernas engagemang
According to Swedish tax legislation, investment funds are taxed differently depending on if the are Swedish or foreign. The difference between the investment funds lies within the taxation of received dividends and the opportunity to shift the liability of tax of received dividends on to the funds shareholders. This measure is only available to Swedish funds. The question in this thesis is whether this difference is discriminatory against foreign investors and therefore constitutes a forbidden restriction against the free movement of capital stated in article 63 EUF Treaty.The European Court of Justice (ECJ) has given several preliminary rulings on this type of legislation and its compatibility with the principle of free movement of capital. It is not compatible with the free movement according to the court.
Förrotation till omrörare
The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
Lanczos potentialer i kosmologiska rumtider
We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
En barnomsorg som inte räcker till : En undersökning om hur nattis framställs i media
This is an examination that investigates how daycare during nights, evenings and weekends, so called ?nattis?, is produced in media with restriction to three big Swedish newspapers during 2004-2012. The main intention and the base to this work is to see how media chooses to produce daycare during nights. As a help to find a result to this main intention there are four questions. These questions are which similarities and differences that can be shown in the articles, which main arguments that can be shown, if it?s a positive or negative picture that the articles are producing and which patterns and themes that can be shown. The method to find an answer to these questions and the main intention were an investigation of 21 articles.
Risk för dehydrering och svält preoperativt. : En kartläggning av preoperativa fasteperioden hos patienter med kroniskt subduralhematom
ABSTRACT The purpose of this medical record research was to study 30 patients with chronic subdural hematoma on a neurosurgical clinic, mapping documented nutritional status, preoperative fasting and hydration and energy supply before surgery. In addition peroperative administration of fluid and vasoactive drugs, as well as postoperative complications and length of hospital stay were studied. The mean age of the patients was 71 years. Nutritional status was evaluated in 12 patients, out of these seven were judged to be at risk for under nutrition. Fifteen patients had surgery day 1 (total fasting time on average m 11 h), eleven had surgery day 2(29 h), three had surgery day 3 (35 h).

Miljöstudier med CFD
Denna rapport behandlar stoftproblematiken i stränggjutningshallen på SSAB Tunnplåt AB i Luleå. Besvärande stoftkoncentrationer i luften har länge varit ett problem för personalen. Syftet med detta examensarbete var att beskriva den nuvarande situationen samt att kartlägga luftflöden med hjälp av CFD (Computational Fluid Dynamics). Även experimentella metoder ingick som en del i arbetet. I ett inledande skede intervjuades personalen för att författarna skulle få ta del av deras förslag och erfarenheter.
Diagnosis of Leber?s hereditary optic neuropathy (LHON) : analysis of MT-ND1, MT-ND4 and MT-ND6 in patients with LHON
Leber´s hereditary optic neuropathy (LHON), a disease affecting vision, is caused by several point mutations in mitochondrial DNA. Mutations leading to a defect NADH ubiquinone oxidoreductase protein will affect the respiratory chain and cause a disturbed ATP production. It is still unknown why this defect leads to the degeneration of retinal ganglion cells and cells in the opticus nerve as well as demyelination of axons in these areas. Analysis of mitochondrial DNA is an important tool in the diagnosis of the disease. At the present time analysis is based on cleavage by restriction enzymes, which only detects two of the most frequent mutations: m.3460G>A and m.11778G>A.
Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper
The dissertation were performed on SP, Technical Institute of Sweden.
The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal.
One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow.
Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible.
The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics.
For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.
Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation
This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming.
The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.
Företrädesrätt till återanställning : - En begränsning enligt bemanningsdirektivet mot arbetskraft som hyrs ut av bemanningsföretag?
In the directive 2008/104/EC on Temporary agency work there is a regulation concerning that there shouldn?t be any restrictions or prohibitions in national legislation if it can not be attributed to the public interest. According to that the purpose of this paper is to investigate whether the Swedish law about reemployment in 25 § LAS is a restriction for temporary work agencies, it?s role on the labor market and also to investigate what consequences a restriction can have from a diversity perspective. To fulfill the purpose I have been using a legal dogmatic method based on determination of the current law.I have by the legal research determined that reemployment is not a restriction for temporary work agencies.
GPU accelerated SPH simulation of fluids for VFX
Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.
Krav på exportlicens vid gränsöverskridande transporter av farligt avfall inom EU
The purpose of this essay is to draw attention to the obstacles that affects the internal trade of waste within the EU. The essay doesn?t in any way encourage pollution or illegal handling of waste but unfortunately there are large profits to be made from illegal destruction and recycling of waste and especially hazardous wastes. Therefore the dependable companies handling waste must access a market with fast and flexible (but predictable) regulations as well as lower transaction costs to help make the environment better and encourage a strive for increased recycling. There are examples where some waste only can be sent to a land-fill within the country but could be recycled in other EU-countries.
