Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.

NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
Vattenkemin i Fyrisån under snösmältningen
Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.
Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica
Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).
Kloridutlakning från flygaska : möjligheten till en lokal hantering
In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.
Kön och genus relaterat till smärta i upplevelser, uttryck och behandling
One area of responsibility for a nurse is to alleviate suffering. Gender
research has shown that there are differences between men and women.
The aim of this literary study has been to elucidate men and women’s
experience and expression of pain and to examine to what extent sex and
gender influence which treatment the patient receive. The study is based
on 21 scientific articles from the databases PubMed and Cinahl. The
result shows that women experience and express more pain than men,
postoperative and experimental. It is however not possible to draw any
general conclusions in terms of the need for men and women to be
treated in different ways.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
Död och begraven : en analys av de avrättades behandling på galgbacken
This paper concerns the treatment of people at execution places and it is focusing on Gotland and the execution place called Galgberget. The material in the paper comes from Galgberget and a gallow in Denmark called Slots Bjergby. Together with this the laws of Gotland during the medieval and later periods are discussed and also how the archaeological material (especially the buttons) found on the excavation site can help to understand the people buried on the gallow site. The result of the analysis shows that the laws and the material found on the excavation site often tells different things. The punishments are often softer then what the law says.
Marte meo - "Show me" sade Maria: En kvalitativ studie av Marte meo terapeutens upplevelser och yrkeserfarenheter av metoden inom socialt behandlingsarbete
This thesis puts focus on Maria Aarts method "Marte meo" (on one's own strength). With the video camera as a principal tool, the purpose of the method is to be a practical working tool to support developmental processes on specific target groups, for example parents and their children. The aim of the thesis was to describe Swedish Marte meo Therapists and Marte meo Supervisors personal- and working experiences of the method, which was introduced in Sweden year 1991. Central questions were: How does Marte meo Therapists describe the essence of the method, it's establishment, development, and future in Swedish social services and psychotherapeutic treatment work? Which are Marte meo Therapists opinions of the methods relation to general problems and issues within social services and psychotherapeutic treatment work, such as the anchorage of theory and practice and the general claim for more research in social services interventions? In order to achieve the aim of the thesis a qualitative study was performed containing semi structured interviews with three Marte meo Therapists (two of them also titled Marte meo Supervisors).
Vägen ur ett alkoholmissbruk -En kvalitativ studie om sex före detta alkoholmissbrukare
The aim of this study has been to take part of six ex-alcohol addicts? narratives about their lives with starting-point in which factors that has been significant and/or determining to be able to leave a life in abuse and what change this process has implied for their identity. To achieve the purpose with this study has three questions been formulated. These are what in the person?s life have been important in the process of a life free from alcohol, what were specific and decisive that effected the decision to stop using alcohol and what is the attitude to them self and their new role as an ex-alcohol addict. Alcohol is a drug that is legal and accepted in the society and it´s hard to discover an addiction.
?Nu förstår jag!? : En undersökning om hur barns förståelse för vattnets väg till kranen kan utvecklas genom en pedagogisk aktivitet
Syftet med det här examensarbetet var att undersöka 3-5 åringars förmåga att utveckla sin förståelse för vattnets väg till kranen genom med en pedagogisk aktivitet. Genom den pedagogiska aktiviteten gavs barnen möjlighet att färdas genom vattensystemet med sina kroppar och sinnen, från sjön till kranen. För att kartlägga hur barnens förståelse utvecklats genomfördes kvalitativa intervjuer före och efter den pedagogiska aktiviteten.Jämförelsen mellan resultaten av förintervjuerna och uppföljningsintervjuerna pekar på en tydlig utveckling av barnens förståelse av vattnets väg till kranen, som ett tekniskt system. Flera av barnen utvecklade sin förståelse för att vårt hushållsvatten måste genomgå en reningsprocess, färdas genom olika komponenter i vattensystemet och rör innan det slutligen når kranen och kan förtäras..
