Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and maintenance costs and costs for the fuel and ash handling.
En undersökning om fallolyckor med gångtrafikanter
The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.
Den självskattade hälsan hos anställda på industriföretag, i relation till användandet av hälsofrämjande förmåner.
This cross-sectional study investigated the use of health benefits in relation to the self-rated health of employees at two medium-sized industrial enterprises in Hälsingland. The method used to investigate this was through a self-designed questionnaire consisting 19 questions about health, lifestyle and health benefits at the workplace. A total of 100 questionnaires were distributed in the two companies, hence 50 surveys at each workplace. The response rate was measured to 88 % and 74 %, which means a loss of 6 persons and 13 persons. The results showed that Company nr 1 offers its employees a health benefits consisting of free access to gym in the company premises after working hours and financial contributions to training-cards.
Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Jämkningsregeln 29:5 ABL : -Jämfört med motsvarande dansk rättsregel
There are no set guidelines on how to interpret the criteria?s in the adjustment rule within the meaning of the companies act. The criteria?s are not discussed in literature and the Swedish case law in this area is very limited. A reason for the limited use of the adjustment rule is the slow and very costly process, which does not grantee the outcome of the case.
Småskaligt vattenkraftverk i Nyköpingsån
Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.
DISPUTERAD OCH KLAR- ÄNDÅ INTE ANSTÄLLNINGSBAR. Personalens upplevelser av anställningstrygghet och karriärmöjligheter vid ett svenskt universitet
This study examines university employees? perception of their employment situation and career opportunities. By tradition, fixed term contracts are used in the Swedish research community due to dependency on insecure funding. There is a current debate that questions this use of insecure employments. The employments are said to negatively affect the university?s societal role and international competitiveness.
Förlustspiralen : En studie av riskbeteende i spelet Black Jack.
Den traditionella förväntade nyttoteorin har kritiserats för att inte vara realistisk i sina förutsägelser om hur beslut tas vid risk. Eftersom de flesta situationer innefattar någon form av risk är det viktigt att utreda ifall man bör söka efter en alternativ teori. I denna uppsats undersöks hur väl nyttoteorin och en konkurrent till denna, prospektteorin, kan förklara riskbeteendet hos Black Jack-spelare. Detta görs genom en studie av fem individers spelbeteende på en krog i centrala Jönköping. Materialet analyseras både grafiskt och statistiskt genom att undersöka om individernas beteende förändras beroende på utfallet dels i de fem senaste händerna och dels under hela spelomgången.
En analys av centralkylan i Slakthusområdet i Stockholm
In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

Landsbygd i förändring : en jämförelse mellan bouppteckningar från1840-talet och sekelskiftet 1900 på Gotlands södra landsbygd
During the beginning of the 19th century Sweden is effected by the Napoleonic Wars and in the aftermath of the war Sweden looses Finland to Russia. This loss leads to the dismissal of King Gustav IV Adolf and the introduction of the Bernadotte dynasty on the Swedish throne. Over the century the industrialization plays a big part in the progress of Sweden. The growth of the industries leads to developments in the areas of agriculture. With this essay I would like to examine if the people on the countryside of Gotland keep the same pace as the people on the mainland in their introduction of new things.
Funktionell validering av mutation i PUS-1 i en patient med mitokondriell sjukdom
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.
Fartförlust på grunt vatten : En jämförelse av bränsleförbrukning och tidsåtgång för rutter med olika djup och distans
Denna studie handlar om den fartförlust och därmed den ökade energiförbrukningen som drabbar fartyg på grunt vatten. Syftet var att ta reda på hur mycket kortare en grund passage behöver vara för att den ska vara ett bättre alternativ än en lång och djup rutt med hänsyn till bränsleförbrukning och tidsåtgång. Resultatet av detta blev att det inte går att dra några generella slutsatser som gäller för alla fartygstyper men att det går att se tydliga tendenser. Studien hade även som målsättning att skapa ett underlag som skulle kunna användas av nautiker vid planering av resor, detta presenterades i form av en sammanställning av de resultat som erhållits vid beräkning av fartförlust i öppet vatten. Någon sammanställning gjordes inte för begränsat vatten eftersom exempelfartygen där fick likadana resultat vilket skulle ha gjort en sådan överflödig.
