Höjdtillväxt, överlevnad och skador i praktiska etableringar av hybridaspbestånd i södra Norrland, anlagda 2004-2011

Hybrid aspen is a crossbreed between European and North American aspen. It is a fast growing tree species that has shown strong growth in the South of Sweden. The follow-ups that have been made on hybrid aspen stands, have mainly been done on plant material in the South of Sweden. In the North of Sweden, only occasional studies have been made, and the knowledge of Northern hybrid aspen stands is, thus, unsatisfactory.In the South of Norrland, land owners have planted hybrid aspen, but what kind of plants it is, and how well these stands have established, is not ascertained, since data has not been compiled on the subject.The objective of this study is to evaluate practical plantations of hybrid aspen in the South of Norrland regarding height growth, survival and damages. The ambition is to increase the knowledge about practical plantations regarding height growth, survival and damages, and from the conclusions thereof, give recommendations for future establishments of hybrid aspen in the area.For the study, eight hybrid aspen stands in the South of Norrland were localised.

Utvärdering av dimensionell stabilitet i PWR-patroner i Ringhals

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.

Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota

The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.

Spårtaxisystem i Uppsala

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Sjuksköterskors upplevelser i mötet med mågkulturella patienter

Bakgrund LCHF (Low Carbohydrate, High Fat) är en lågkolhydratskost som fått stort genomslag i Sverige. Svenska Livsmedelverket är oroliga för hur denna utveckling kommer att påverka folkhälsan, framförallt då kolesterolnivåerna i landet under samma period ökat. Förespråkarna av kosthållningen ställer sig däremot frågande till rådande rekommendationer och menar att det är dessa som gör oss feta och sjuka. Trots debatten fattas det data på hur en LCHF-kost faktiskt ser ut.     Syfte Syftet med denna studie var att kartlägga hur en LCHF-kost ser ut gällande livsmedelsval och näringsintag och utifrån det diskutera kosthållningen ur ett folkhälsoperspektiv.Metod 14 individer som ansåg sig äta enligt LCHF rekryterades till att utföra en vägd kostregistrering under tre dagar.

Value at Risk : En kvantitativ studie av Historical Simulation Approach och Simple Moving Average Approach

Bakgrund Det finns stora risker att personer med autism och utvecklingsstörning har ett problemskapande beteende. Omgivningen behöver tydliga rutiner och ett genomtänkt bemötande i kritiska och våldsamma situationer. Personalen spelar en avgörande roll för händelseutvecklingen. Ett lågaffektivt bemötande erbjuder metoder att förebygga och hantera problemskapande beteende på ett icke-kränkande och icke-våldsamt sätt genom flexibel kravanpassning.Metod Tre fokusgruppsamtal med sammanlagt 12 pedagoger på tre olika särskolor för elever med autism. Samtliga pedagoger har det senaste året gått en tredagarskurs i lågaffektivt bemötande.

Effekter av kolhydraträkning vid diabetesdebut hos barn och ungdomar : En registerstudie

Abstract Aims and objectives. To examine whether an intervention with carbohydrate- counting at onset of type 1 diabetes in children, has had any effect on metabolic indicators such as HbA1c , BMI-sds and total daily insulin / kg, 2 months and 1 year after onset by age and gender .Background. The pediatric department at the university hospital of Norrland in Umeå (NUS), has since several years a higher average HbA1c among children 0-17 years, compare with pediatric departments in the rest of Sweden.  Therefore, in autumn 2011, an intervention was made to teach children with diabetes and their parents to count carbohydrates from the onset of diabetes. Using this method they can regulate their insulin doses depending on the amount of carbohydrates they are eating.Design. This is an empirical registry study done on the basis of a quantitative method.

Vindkraft eller kärnkraft - En jämförelse

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Lätt räknat : En utbildningssociologisk studie av matematiklärarstudenters sociala ursprung och utbildningskapital

A change has occurred in terms of recruitment to teacher education. From having been an educationof high status and reputation, a reduced application rate has led to lower admission requirementsand thus that students with much lower educational qualifications entering, which in turn means thatthe education status and reputation have been reduced significantly. Mathematics, on the other hand,has always been a topic of high status and reputation. Although there are few students who chooseto study to be a mathematics teacher. By conducting a survey of students on teacher educationtoday, both with mathematics and other approaches, I wanted to get answers to my questions aboutwhat influences students' choice of education: who are the students studying to be teachers inmathematics? Do they distinguish themselves from the student teachers who studies to be teachersin other subject specializations? Pierre Bourdieu's sociological ideas about cultural capitaltransmitted from parent to child constitute the theoretical framework of the study.Early in the study, I noticed that there is a difference between students studying to be a teacher inpreschool, primary or middle school and them studying to be a teacher in secondary and highschool, especially in terms of the mathematics student teachers.

Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer

Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.

Effektivitet i grundskolan - en studie om Leans applicerbarhet på processen utvecklingssamtal

Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.

Demokratins tjänare eller medielogikens lakejer? : En studie av fyra tidningars gestaltning av politik i samband med riksdagsvalet 2014.

From a democratic viewpoint, the way in which the media frames politics is essential. Should issue frames be left out in favor of other types of frames, it could result in voters struggling to make informed decisions come Election Day. What is more, research shows that game frames may cause lack of confidence in politicians and declining political interest. Against this background, the present study aimed to find out how two broadsheets, Dagens Nyheter and Svenska Dagbladet, and two tabloids, Aftonbladet and Expressen, framed politics in connection with the 2014 Swedish parliamentary elections. The thesis also intended to identify possible differences between the two newspaper types and to make tentative comparisons with previous studies so as to be able to comment on framing developments.

Varfo?r finns det sa? lite svensk ekologisk frukt? : probleminventering av den svenska ekologiska fruktbranschen

Out of totally 1862 hectares of the Swedish fruitacerage, only 142 hectares are cultivated according to the EU-standards for organic farming. Only 73 hectares are connected to the Swedish control organisation KRAV. Therefore only fruit from this acreage can be sold as organic. The aim of the study was to further investigate the organic fruit production regarding cultivation, market and firm strategy. Through interviews with 36 fruitproducers the situation for organic fruit and the companies were examined.

Rekryteringsstrategier för företag inom skogssektorn : en undersökning om hur skogsbrukande och träförädlande företag bygger sitt arbetsgivarvarumärke

The forest industry is anonymous among the young people of today. Many youngsters do not know what the forest industry has to offer. As a result of this, many schools and forest have a weak recruitment. This is not a problem for Sweden and the forest industry only, many other businesses companies suffer from in Sweden and other countries in Europe share the same image problem. The interest and values of young people drives them to look for opportunities in other betterknown sectors with better image and reputation. Many companies report having problems with recruiting the best and right employees and fear that the recruiting-problems will increase when the older generation born in the 1940?s will retire.
