Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd
Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method.
This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.
Hur kan intresse utvecklas för fysik och kemi i grundskolans tidigare år : - En analys av tidigare forskning
I den senaste PISA undersökningen från 2012 testades elevernas kunskaper i matematik, läsning och naturvetenskap hos femtonåringar runt om i landet. Sverige var det land som försämrat sina resultat mest av alla deltagande länder inom samtliga områden. Detta tyder på att något måste göras. Vi har studerat hur man kan väcka intresse för ämnena fysik och kemi inom naturvetenskapen. Detta för att öka de naturvetenskapliga kunskaperna hos eleverna i skolan.
Jag är viktig : Verksamma lärares tankar och arbete kring flerspråkiga elever
According to international and national literacy studies (PISA, PIRLS) Swedish boys are inferior to Swedish girls when it comes to reading. There can be numerous reasons to that statement. One is that Swedish teachers require more knowledge about communication as an important component in literacy. In spite of this shortcoming, Swedish girls manage to gain sufficient literacy. Why is that? The aim of this survey was to examine if there were any differences between girls and boys regarding communication skills when they begin in school.The main questions taken in account were:Which differences and/or similarities in communication skills are discernible between boys and girls this particular preschool?How do boys and girls communicate with each other in different room contexts on this particular preschool? To be able to answer the questions, I adopted observations and audio recordings from children aged five.
Produktion av marknadsförings- och korrespondensmaterial för DUCIS
The report describes the production of graphic correspondence and marketing material for DUCIS(Dalarna University Centre for Irish Studies).A logotype symbol is created on the basis of an element from the Celtic art, and a graphic material thatharmonies with this ideal of style is built around the symbol. A unique visiting card, correspondence cardand letterhead is produced to strengthen the identity of DUCIS outwards.The work proceeds with an international education folder which is an important element in the marketingwork for the MA-education which starts in the autumn of 2003. Two posters, one for the opening ofDUCIS in may 2003 and one for a conference in 2004, are produced. Finally, a redesign of the book coverfor NIS, Nordic Irish Studies, is carried out.The report describes the working process consisting of meetings, practical work and other elementswithin the process. The conclusion is that the work has been quite successful and that this, to a largeextent, depended on an engaged and supporting commissioner.
Textinnehållets betydelse för läsförståelsen : En komparativ studie av flickor och pojkar i åk 7
Research reports as PISA and PIRLS show that reading comprehension among Swedish students have deteriorated in recent years and that girls have better reading comprehension than boys. The basis for this study is Maj-Gun Johansson's reading comprehension test done during the four years between the years 2005-2008 in the seventh grade in a municipality in Sweden. The main purpose of this study is to examine reading literacy in terms of the influence of content and form of texts viewed from a gender perspective. The study is divided into two parts. The first part is a survey on local reading comprehension compared with results from a similar national text.
Hållfasthetsberäkning av två T-stycken på fjärrvärmerör enligt SS-EN 13941 2003
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Hur ofta bör småhus sotas? : En samhällsekonomisk analys av ändrade sotningsfrister
Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions. Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.
Redovisning av humankapital -en jämförelse mellan kunskaps- och verkstadsbolag
Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

Retrospektiv studie av porcint circovirus typ 2 och postweaning multisystemic wasting syndrome i Sverige :
Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world.
PCV2 has been pointed out as the major causative agent to post weaning multisystemic
wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS
are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy
enlarged lymph nodes with depletion of lymphocytes are commonly found.
Since 1991 PMWS has spread all over the world and was first described among Swedish pigs
in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases.
Why this is and what other factors that are required in order for the disease to develop is yet
unknown. The main theories involve other infections, for example PRRS, and management
issues but also genetic differences between pigs and/or virus strains have been suggested.
Boys don't cry : En studie om hur åtta 5-6 åringar konstruerar kön utifrån normbrytande barnböcker
Denna studies syfte är att undersöka hur barn konstruerar kön utifrån normbrytande barnböcker. Därmed vill vi skapa förståelse för hur barn kan tänka och resonera kring könskonstruerande. Studiens upplägg är inspirerat av Davies (2003) forskning och den teoretiska utgångspunkten är den feministiska poststrukturalismen. För att söka svar på våra frågeställningar har vi använt oss av en kvalitativ metod, vilken har integrerat en kombination av boksamtal och barnintervjuer. Undersökningsgruppen bestod av åtta 5-6 åringar, varav det var lika många barn av respektive ålder och kön.
Postapokalypser, robotar och zombies : En studie om dystopiska temaarbeten i årskurs 9
Syftet med den här uppsatsen var att analysera 73 dystopiska temaarbeten, skrivna av elever i årskurs 9 vårterminen 2012, och undersöka om man finner någon skillnad kvalitetsmässigt mellan kvinnliga och manliga elever och ta reda på vari dessa skillnader i så fall ligger, i hopp om att det ska ge en tydligare inblick i problematiken kring svenska elevers dalande studieresultat. Med hjälp av textanalys som kvalitativ bedömning anonymiserades uppsatserna, de fem delarna som arbetena bestod av bedömdes och sedan summerades slutligen bedömningen i tre kategorier: svaga, neutrala och starka uppsatser. Därefter delades de in dem efter åtta återkommande teman/genrer: Science Fiction, Natur-/miljökatastrofer, Zombies, Politiska, Corporate, Gudomliga, Postapokalypser och Epidemier/Pandemier. Uppsatserna delades sedan in efter kön och analyserades för att se vilka samband som kunde hittas mellan insatser/resultat och temaval och populärkultur/finkultur. Det jag fann var att pojkarna inte bara presterat bättre än i tidigare forskning, utan även bättre än flickorna i undersökningen ? vad gäller toppskiktet.
Beskrivning och analys av superovuleringsresultat och andra fertilitetsregistreringar vid Nötcenter Viken :
Recording and analyses of superovulation results and fertility records at the nucleus herd Viken
The development of different reproductive technologies aim at increasing the number of progeny per individual parent, and in that improving the possibility of genetic progress. One technique, embryo transfer, have facilitated genetic dissemination and shortened the generation interval also in females.
Nötcenter Viken is a company that run embryo collection and embryo transfer in the breeds Swedish Red and Swedish Holstein. It is located outside Falköping. Information is continuously gathered about cows tested at the nucleus herd.
