Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques

Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

Sova med fienden - Orsaksförklaringar till uppkomsten av oheliga allianser i svenska kommuner

Over the last years there has been a considerable change in Swedish municipals. The number of municipals run by a rainbow coalition, a coalition made up of parties from different political blocks, has increased dramatically. Despite this clear pattern little research has tried to explain this increase. My thesis? aim is to try and clear the water around this subject by answering three questions about this type of coalitions.

Inventering och riskklassning av förorenade områden i Öna och Östnor :

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The effect of vegetable fat on cheese yield and cheese properties

The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese. The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used. The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties. The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.

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.

Kan grad av degenerativ hjärnsjukdom prediceras med hjälp av mått på kognitiv försämring?

Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.

Den traumatiserade sexualiteten : En litterär motivstudie av sexualitet i Raymond Carver's "So much water so close to home"

Denna studie erbjuder en litterär analys av gestaltandet av sexualitet i den amerikanske författaren Rymond Carvers novell "So much water so close to home". Analysen lyfter bland annat fram den obligatoriska heterosexualiteten som den teoretiseras av Adrienne Rich och hur manlig kontroll av kvinnans sexualitet inom den heterosexuella institutionen tar sig uttryck i texten.Utöver det undersöks i analysen vilka principer som kan anses ligga bakom konstrueringen av sexualitet i novellen samt hur dessa tar sig uttryck. Den aspekten av analysen tar avstamp i Judith Butlers teori om diskursivt skapade kön och genus samt den heterosexuella matrisen som utgångspunkt för all sexuell åtrå. .

The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

UNSCR 1960 : En analys utifrån feministiska teorier

? Does Karlstad municipality have adequate institutional conditions to make the best use ofthe citizens? proposals??The purpose with the thesis is to investigate if citizens? proposals lead to a broader politicalinfluence. To answer that, I have done a case study about how Karlstad municipal administers citizens? proposals. The research assignment is: Does Karlstad municipal have adequate institutional conditions to make the best use of the citizens? proposals? The perspective is a democracy perspective and the theory is institutional theory and policy process theory.A selection of citizens? proposals that have arrived to Karlstad municipal between 2008 and 2010 have been studied in detail to analyze how the proposals have been administered and if it matters how the proposals are phrased.

Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Konstruktion av testrigg för moderna ångexpandrar

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

Leder ökat individuellt inflytande till minskad stress? : Undersökning av tjänstemän inom Karlstad kommun.

AbstractThe purpose of this study is to examine whether the individual influence at the working place leads to the perception of decreased stress. Also I looked at whether stress and individual influence is affected by the employees age, sex or employment years. Previous research shows that individual influence decreases stress but strangely enough do the research show that individual influence seem to decrease in today?s work environment. This research is quantitative with questionnaires, answered by 74 civil servants working in a department in the municipality of Karlstad.
