Geoenergilösning för DN-huset

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :

During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.

Biologisk bekämpning av Fusarium graminearum

Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.

Inokulmmängdens betydelse för utveckling av vetets stråbasröta orsakad Fusarium graminearum : utvärdering av ett biotest

Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.

Sveriges ensamkommande barn. En studie av konstruktionen flyktingbarnet.

Children who have fled to Sweden, without their parents or guardians, have been a controversial subject during the winter of 2002. Their situations on refugeestations and the responsibiliy by community and the state have been discussed. My composition is about these children. The composition is not about the situations of the children - focus is instead on the people who operate with the children; community, state and organisations. I want to find empirical levels which show what the children associate with.

Ledarskapets betydelse i subarktisk miljö

Att verka med ett militärt förband i subarktisk miljö är krävande då det alltid finns en naturlig fiende närvarande ? den ständiga kylan. Det finns mycket skrivet om ledarskap, subarktisk miljö och Finska vinterkriget men jag har inte funnit något om ledarskapets betydelse i subarktisk miljö. Syftet med denna uppsats är att undersöka om utvecklande ledarskap är en applicerbar ledarstil i subarktisk miljö. Denna uppsats bygger på kvalitativ text analys med en analys av subarktisk miljö, utvecklande ledarskap samt om Finska vinterkriget 1939-1940.

Energikloka hus i Järinge - energiteknisk uppföljning

Energy-wise houses in Järinge - technical follow-up The company JM built energy-efficient houses in Tensta in Stockholm. They have built a total of 16 houses divided into two parts of A-houses and B-houses. The buildings are an attempt by JM to minimize energy-use of the buildings without affecting the comfort and living standards. The project aims to examine the data for the 16 houses on the basis of data and produce a report showing how the buildings worked through a technical perspective. JM approximates that the purchased energy will not be higher than 95 kWh/m2 per year.

Vädrets påverkan på byggarbetsplatsen

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Behövs kommunal fritid?: en kritisk diskursanalys om fritidschefers egen syn

Uppsatsen hade som syfte att belysa om kommunal fritid behövs. Undersökningen bestod av samtal med fyra fritidschefer på deras fritidskontor. Samtalen tolkades hermeneutiskt och analyserades med Faircloughs kritiska diskursanalys (Winter Jørgensen & Philipps, 2000). Som teori utgicks från Habermas diskursteori (Habermas, 1995). Analysen visar att kommunal fritid är stadd under stark förändring och har gått från "inte" till att "vara".

Fuktproblem i chilenska småhus

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.

Snöoväder i Sverige 2004-2014 : En statistisk sammanställning samt en utvärdering av tidningsartiklar som källa

Transport is an important aspect to take account in efforts to achieve sustainable tourism development. If we do not change our behavior regarding travel, the consequences will be significant for the environment. This study examines the various transport operators on the two Swedish ski resorts if their websites and marketing are different from each other in the mode selection. The destinations are Åre and Hemavan Tärnaby. They studied modes are two Swedish airlines, two train companies, three bus companies and three taxi companies.These corporate websites are studied with a content analysis in which the results of the keywords that have been developed are scored according to different categories.

Prognostisering av försäkringsärenden : Hur brytpunktsdetektion och effekter av historiska lag? och villkorsförändringar kan användas i utvecklingen av prognosarbete

I denna rapport presenteras ett tillvägagångssätt för att hitta och datera brytpunkter i tidsserier. En brytpunkt definieras av det datum då det skett en stor nivåförändring i tidsserien. Det presenteras även en strategi för att skatta effekten av daterade brytpunkter. Genom att analysera tidsserier över AFA Försäkrings ärendeinflöde visar det sig att brytpunkter i tidsserien sammanfaller med exogena händelser som kan ha orsakat dessa brytpunkter, till exempel villkors- eller lagförändringar inom försäkringsbranschen. Rapporten visar att det genom ett metodiskt angreppssätt går att skatta effekten av en exogen händelse.

Utsläpp av växthusgaser under islossning i små boreala sjöar

Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.

Spillvärmeåtervinning

SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.
