Tillväxthastighet och storleksfördelning hos hassel (Corylus avellana)

To increase the knowledge about the growth of hazel (Corylus avellana)and size distribution of the shoots, circumference and stem diameter wasmeasured in a total of 54 clones in two areas in Östergötland. Further, thewidth of growth rings was determined for separate years. The diameter ofthe stems was measured both out from the centre of the stem andperpendicular to the first measure. The stems showed only a weaktendency to have an oval shape (with the longest side outwards from thecentre). The growth model did not improve when the degree of sunlightof clones was taken into the account.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

Detektion av kolvläge i hydraulcylinder med elektromagnetisk metod

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.

Ledares syn på avhopp inom ungdomsishockey : En kvalitativ studie bland ledare i Norrbotten om vilka faktorer som påverkar avhopp

Dropout among youth players is a problem in Swedish icehockey. Leaders in youth hockey teams work closely with players on an almost everyday basis during season and have a big influence on players and their activities. This study aims to identify possible reasons for dropouts by interviewing coaches and leaders in icehockey clubs. A total of eight coaches and leaders in different ice hockey clubs were interviewed. Results show that the coaches highlight three reasons for early dropout; focus on competition, results and too much training in younger ages..

Omkonstruktion av armled tillhörande Bracke Forest högläggare

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

Hur påverkar förtätningen stadens grönstruktur? :

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

Artificiella sötningsmedel i dryck och dess effekt på hungerkänslor och energiintag

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Artificial sweeteners in beverage and their effecton hunger and energy intakeAuthor: Sofia Andersson and Sofia JakobssonSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2012BackgroundIn 2010 the total consumption of soft drinks in Sweden was estimated to 69 litres per person and17 % of the domestic production was estimated to consist of soft drinks sweetened with artificialsweeteners. The effects of artificial sweeteners on hunger is not yet fully understood. It isspeculated that they might increase hunger and hence increase energy intake.ObjectiveThe aim was to compile the evidence regarding the effects of an intake of a beverage sweetenedwith artificial sweeteners compared to sucrose on subsequent hunger and energy intake.Search strategyA systematic search for literature was performed in the databases PubMed and Scopus.Selection criteriaThe inclusion criteria were RCT, human studies, articles published in Swedish or English, studieson healthy adults and studies measuring hunger with a subjective scale or energy intake. Theexclusion criteria were studies who measured energy intake under other forms than standardisedor controlled, studies without a standardised dose of the beverage and articles needed to beordered against payment.Data collection and analysisFour articles were selected and examined according to a template developed by SBU. Theevidence for each outcome was weighed together and graded according to GRADE based on asummarised evidence form developed by the Sahlgrenska Academy.Main resultsAll four articles measured subjectively rated hunger.

Vd-ersättning : en empirisk studie av 43 börsnoterade företags bonusutdelningar

Bakgrund: Bonussystem är något som började växa fram under 1980-talet och är ett inte sällan förekommande debattämne. Inte minst i dagens situation med en stark recession och en finansiell kris om knuten. Flertalet artiklar har tagit upp ämnet, där man har ifrågasatt olika företags utdelning utav enorma rörliga ersättningar trots den svåra tid vi nu befinner oss i. Företagen motiverar olika andledningar till varför de väljer att betala ut bonusar till sina vd:ar, som grundar sig på olika typer av variabler.Syfte: Uppsatsens syfte är att undersöka vilken typ av variabler som visar starkast korrelation med storleken på företagsledarnas bonusar, och att se om dessa kan tänkas påverka deras risktagande.Metod: Uppsatsen bygger på en kvantitativ undersökning av sekundärdata som har inhämtats från de utvalda företagens årsredovisningar. Undersökningen tar en deduktiv ansats, där de valda teorierna appliceras på de resultat som undersökningen visar.Resultat: De fem företagen som betalar ut högst total ersättning är ABB, Ericsson, AstraZeneca, Getinge och Scania.

Arbetslöshetens bestämningsfaktorer i ekonomisk-historisk belysning - En analys av lönebildning, totalfaktorproduktivitet och löneutrymme under perioden 1911-1960.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

August Strindbergs arkiv från privatarkiv till kulturarv: En studie i proveniensprincipens tillämpning och nationalistisk historietolkning.

In this thesis I examine the events that followed the death of August Strindberg and resulted in his private belongings becoming an important part of Swedens cultural heritage. My purpose has been twofold: firstly, to identify which aims were sought to be achieved when dealing with Strindberg's archives and his home and to relate these to a nationalistic interpretation of history, secondly, to relate this work to the then newly introduced archival principle, the Principle of provenance. I identified three different aims: firstly the economic aim must be seen in the light of an increasingly expanding publishing market. I argue that the author gained a new and important role in the general social debate a nationalistic one, an important point with regard to my following conclusions. Secondly, the aim to store and display the material in a museum is discussed in relation to different views of cultural history and the interpretation of history.

Upplevd arbetsmiljö : En kvalitativ studie om omsorgsgivares erfarenheter av ledningens och organisationens inverkan på deras arbetsmiljö

The aim of this essay was to describe and interpret the managements and organizations impact regarding the caregivers working conditions. To examine this we used a qualitative method. We completed two group interviews and five individual interviews with a total of fifteen enrolled nurses that worked within elderly care. In our interviews we found that the enrolled nurses felt that the organizations economic interests collided with their personal values regarding good quality elderly care. We also found that the caregivers experienced that they had an impact on their working conditions and that their employer was the main reason for making it possible..
