Analys av energianvändningen i kvarteren Carolina och Jenny : en fallstudie
An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.
Igloo
This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection.
Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :
In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead.
This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.
Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Fuktens påverkan på utegipsskivor under byggtiden
This thesis is a study of humidity at Knauf Danogips external plasterboard. The study is performed at the building project Kv. Maskinen in Jönköping in cooperation with NCC Construction AB and Knauf Danogips. The measuring was performed during five winter/spring months to see how the weather influenced the plasterboard.The measuring was performed at a small two-storied building and a larger fourstoried building. From the buildings` placement were a couple of measuring dots selected and to get a good result was the dots located in the four cardinal points.
Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv
Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Bemötande : En observationsstudie om hur flickor och pojkar bemöts i förskoleåldern
The aim of this study is to examine metaphors and what may be perceived as motif-circuits in Stig Dagerman?s play Den dödsdömde (The Man Condemned to Death) and the two short stories ?Den dödsdömde? (The Man Condemned to Death) and ?Mannen från Milesia? (The Man from Milesia). My intention is to discuss a single theme and identity-marks that unites all three works, using Paul Ricoeur?s The Rule of Metaphor (La mêtaphore vive) as well as the ?thematic critique? of Jean-Pierre Richard.What is metaphor for Ricoeur is for Richard themes (theme): an organizing principle, a sort of schedule around which a world is constituted. Hence, I find similarities between the motif-circuits, Ricoeur?s metaphor-theory and Richards?s themes.
Koldioxidavgång vid ekologisk odling på organogen jord
The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.
Studie och riskanalys av sulfidleror i Uppsala stad
Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.
Ekologisk slaktgrisproduktion i Sverige :
This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.
Företaget i varseltider : Påverkan på dess effektivitet och produktivitet
Syftet med studien är att undersöka varsels effekter för företags effektivitet och produktivitet under lågkonjunktur. Vår studie bygger på intervjuer med både chefer och anställda från företaget Water Jet Sweden AB. Studiens resultat är att personal påverkas av företags beslut om varsel om uppsägning genom att arbeta mindre effektivt. Detta är så för att varslet sänker arbetsmotivationen och tryggheten vilket gör att personalen underpresterar, detta påverkar hela företaget negativt..
