Sommargården - Hållbara uppvärmningsalternativ för stugbyn Sommargården, Finnhamn

Finnhamn is a group of islands that are located in the middle north part of Stockholm?s archipelagos. On the main island Stora Jolpan there is a camp called Sommargården, which consists of eleven different buildings in various sizes. The assignment given by the Archipelago foundation (Skärgårdsstiftelsen) is to analyze if it?s benefited to replace Sommargårdens current heating system that consists of electricity radiators, with a more energy efficient heating system. This research is done with help of the literature review and a visit to Finnhamn in order to map Sommargården?s current state and its energy usage.

Förslag till bebyggelse och park i kvarteret Seminariet i Uppsala

In the urban planning debate of today, two strategies for city development stand out as each other's opposites, urban sprawl and smart growth. This thesis concerns a development project of the latter kind and aims to give an alternative proposal to new buildings and a park in a Swedish city block. The term sprawl is used for new developments on virgin soil on the outskirts of cities leading to a city spreading, while smart growth stand for increased city density through development on re-used land within the city boundaries. The latter are often seen as more sustainable in many levels and are also shown to have positive effects on a number of city functions. At the same time smart growth has negative consequences on other aspects of the city such as public open spaces.

African swine fever in Uganda : description of a recent outbreak and possible differential diagnoses

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

Helandet av Stockholms sår : En analys av projektet Västra City

Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.

Vilka är dagens krav på gårdsverkstaden? :

After been told that an ordinary winter service for our combine should cost more than 20000 SEK, not included spare parts, I decided to write this paper about today?s requirement of the workshop on a farm. I think that the lack of proper premises is the reason way not more of the ordinary machinery maintenance or upkeep is performed on the farm. When I did my literature survey I found that the Swedish environmental code, set by the Swedish law regulate how drain or sewer should be built. The environmental code however leaves a lot for your own interpretation. It might not be so bad but it must be very hard for the local environmental office to interpretation the regulations, since they are the ones that gives permission for the sewer in your workshop.

Ersättning av fossilt bränsle i värmeproduktion: Pulverbrännare till befintliga oljepannor

Vi står inför en förändring, att minska vårt beroende av fossil energi till förmån för en ökad användning av förnybar energi. Incitament i form av ökade punktskatter på fossilt bränsle påskyndar omställningen för företag till förnybar energi och- eller energieffektivisering av sin produktion. Konsekvensen blir en successivt fördyrad kostnad för produktion av fjärrvärme med eldningsolja till tillverkningsindustrin. Punktskatt på eldningsolja stiger med 41 procent, från 2010 till 2015 för företagen. Att konvertera befintliga oljepannor med träpulverbrännare är en lösning för att hålla produktionskostnaden nere och behålla sin konkurrenskraft.

Termisk hantering av litium-jon- batterier i elektriska drivsystem

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

African swine fever in Uganda : attitudes and possible interventions to limit the spread of the disease

The objective of this study was to investigate the attitude towards African swine fever (ASF) primarily among smallholder pig farmers but also among other actors along the pork value chain in Gulu district, Uganda. More specifically, the study aimed to investigate the specific challenges facing both farmers and other members of the pork value chain using participatory epidemiology (PE). ASF is a feared viral disease of pigs associated with high mortality, which is endemic in many parts of Africa. The recent history of Gulu district in Northern Uganda can be described as turbulent and the human population has suffered during decades of war and civil unrest. Pig keeping is considered a potential opportunity for business as well as a way of providing more animal protein in the diet. However, this is threatened by ASF as farmers can lose entire herds due to the disease. This study can confirm some previously known factors and risk activities such as the free range system of pigs and movement of pigs and pork during ongoing outbreaks, which make disease control difficult.

Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

Energieffektivitet i datahallar

The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.
