Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :
The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.
Implementation of an FFT algorithm using a soft processor core
This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..
Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual.The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls.
Hur är läget? Om självskattning av psykiskt mående via mobila applikationer
Tidigare forskning har visat att systematisk självrapportering är en fördelaktig metod för att följa enpersons psykiska mående över tid, och att en digital mätmetod i sin tur skulle innebära många praktiskafördelar jämfört med en analog. Detta är en experimentell randomiserad, kontrollerad studie som medutgångspunkt i personcentrerad vård och spelifiering undersöker 35 personers användarfrekvens ochattityder efter en tvåveckorsperiod där hälften har fått prova att självskatta sitt psykiska mående via enmobilapplikation, och hälften fått göra detsamma via ett analogt stämningsformulär. Resultatet visar enhögre användarfrekvens bland deltagarna i mobilapplikationsgruppen, samt ett uttalat intresse hosbägge grupper för digitala metoder för självskattning av psykiskt mående. Bägge metoderna ansesstärka personcentrerad omvårdnad. The aim of this study is to explore user frequency and attitudes for persons using a mobile applicationfor assessing mental health compared to persons using an analogue assessment method.
Stress is always present, Stress och coping hos personalen på en kvinnojour
The purpose of this study was to examine work related stressors and related coping strategies among case managers at a domestic violence shelter in the United States. We further wanted to examine whether locus of control among the participants could be related to work related stress and coping strategies. Qualitative interviews were performed with eight case managers to gain knowledge about the stressors and coping strategies they used by examining their thoughts, feelings and experiences. The result showed that the case managers experience a number of stressors in their work environment such as system problems (e.g., lack of re¬sources and time pressure) and emotional stress. Coping responses among the case managers included efforts to alter the problem, so called problem focused coping, efforts to control emo¬tions, so called emotions focused coping and social support from colleagues.
Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
LÖNSAMHETSKALKYL AV FUKTSÄKERHETSANSVARIG VID RENOVERING : En fallstudie av ett projekt där ByggaF-metoden har använts
The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.
Styrning av humankapital utifrån Simons Levers of Control ? ny kärna, nytt analysområde
Företag idag söker ständigt nya och förbättrade konkurrensfördelar, som är en
konsekvens av den snabba och ökande globaliseringstrenden. Ett viktigt
grundincitament för att skapa dessa fördelar samt bemöta omvärldens
föränderlighet och krav har bidragit till att allt större fokus riktats mot
behovet av en bred kompetens, det vill säga ett utvecklat humankapital, inom
företag. Humankapitalet är en av de mest betydelsefulla grundpelarna i ett
företag då företaget är beroende av de anställdas kompetens och
innovationsförmåga. Det är således viktigt att ett företag styr humankapitalet
på ett sådant sätt att det når en stärkande eller förädlande effekt. Ett sätt
för att strategiskt styra förädlingsprocessen av humankapitalet är att nyttja
Simons Levers of Control, vilken även går under benämningen Simons styrmodell.
Att vårda en person som drabbats av stroke : Anhörigas upplevelser
Background: Each year approximately 30 000 people suffer from stroke in Sweden, often with substantial mental and physical consequences. Those who suffered from stroke handled the situation by mourning what they had lost and by accepting their changed body and life situation. For those who provide care for people who has suffered a stroke help and support was required. The caring science perspective was based upon caring and suffering. Aim: The purpose of this study was to describe family caregivers? experiences of caring for persons who had suffered a stroke.
Blivande folkskollärare : En social rekryteringsstudie av inskrivna män vid Karlstads folkskollärarseminarium
The main purpose of this essay is to interpret possible pattern in social extraction, among future male elementary school teachers, at Karlstads elementary school teachers seminar over time. The questions that intend to concrete the purpose, and describe the possible pattern of social backgrounds are following; Where do the future male elementary school teachers come from? How the social recrutiment is divided in professional categorys, and is there any distinction in the pattern of social recrutiment over time? Which social groups were represented at Karlstads elementary school teachers seminar between the year of 1860-1940, and how they were divided.At the categorization of occupation, class- and social belongings I´ve used Sten Carlssons theory of professional categories (the social transformation in Sweden after 1866) which also was used by Kerstin Skog-Östlin in her dissertation Pedagogical control and authortity.The changes in the pattern of social recruitment of male future elementary school teachers were following; the proportion of students with agricultural backgrounds has decreased between the year of 1860 and the turn of the century. Further there was a substantial reduction of students with agricultural backgrounds between the turn of the century and the year of 1940. Students with agricultural backgrounds had the lowest represented frequency according to the investigation.
En retrospektiv epidemiologisk studie om hudproblem på dobermann :
It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company.
The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.

Entreprenörers levnadsstandard: en fråga om personlighet : Kvantitativ undersökning av den materiella levnadsstandarden hos egenföretagare i Sverige
Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income.
En studie om studenters användning av vänlistor på Facebook
Friend lists allow Facebook users to group their friends and may be used to share certain information only with those in a specific list. This function has been around for several years, but has never gained any particular popularity among users, most of whom probably did not know it even existed a couple of years ago. In the fall of 2011, however, the function was updated and made more visible on the site.There are several possible uses of friend lists, such as privacy control, filtering of the news feed, self-presentation and targeted information sharing. This paper aims to investigate the extent to which friend lists are used by students today, as well as why students actually use their lists, i.e. for what purposes.Judging from the results of this study in comparison with earlier research, there seems to have been a somewhat recent increase in the awareness of the fact that friend lists actually do exist, but still most users tend not to utilize them.
