I Göteborg pågår planeringen för en ny tågtunnel som ska binda samman pendeltågstrafiken tillgenomgående linjer. Västlänken, som den kallas, går under centrala staden och två nyastationslägen ska etableras. Trafikplaneringen har en viktig social dimension som inte alltiduppmärksammas i tillräckligt stor utsträckning. Infrastrukturella förändringar påverkar livet istaden, samt hur platser används och uppfattas. I Sverige finns inget lagkrav på att kartlägga socialakonsekvenser av ingrepp och projekt, något som däremot gäller för miljökonsekvenser.

In this project, an area in the small town Tungelsta south of Stockholm, is in focus. Tungelsta is placed in the municipality of Haninge and it is for the planning department on the municipality, this project is made. The task is to compose an arrengement of buildings and open spaces for a 50 hektar area. Today the area is consists of agriculture fields and forests. The area is placed near the railway station, in the city centre of Tungelsta, which makes it interesting and important to work with. There are different opinions about the future plans for the area.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Syftet med arbetet a?r att underso?ka hur byggnadsmaterial behandlas inom BREEAM, LEED, Miljo?byggnad och Svanen samt inom byggvarudatabaserna Basta, Byggvarubedo?mningen och SundaHus. Med hja?lp av systemens bedo?mningskriterier har relevant information bearbetats och sammanfattats i en diskussion samt ett grafiskt resultat.Resultatet har visat att BREEAM-SE sta?ller ho?ga krav med ba?de standardiserade livscykelanalyser, kemiskt inneha?ll, dokumentation, avfallshantering, emissioner och tillverkning. LEED sta?ller krav pa? a?tervinning, a?teranva?ndning och emissioner men na?mner inte utfasningsa?mnen eller fullsta?ndig materialdokumentation.

In this essay a proposal of city renewal is made for the new train station area built on highly productive agricultural land in Landskrona. The proposal is based on how the situation for the agricultural land in terms of exploitation looks like today and also on theories of urban governance to find out why the area turned out the way it did..

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

I Sverige använder man idag BKR och BBK 04 vid dimensionering av betongkonstruktioner vilka, inom kort tid, kommer att ersättas av Eurokod 2. Vid dimensionering av byggnader kommer Eurokod 2 Del 1-1 att användas och med regelverket kommer en hel del nya regler och normer att behöva anpassas. För att undersöka hur BKR och BBK 04 skiljer sig mot Eurokod 2 vid dimensionering av betongkonstruktioner har en balk och en pelare med vanligt förekommande dimensioner studerats. Balken dimensioneras med hänsyn till bärförmåga vid böjning och tvärkraft samt kontroll av sprickbildning. Pelaren dimensioneras med hänsyn till bärförmåga vid centriskt tryck och moment i tvärsnitt på grund av strukturimperfektioner.BBK 04 har gått ett steg närmare Eurokod 2 än tidigare utgåvor och det som skiljer vid beräkning av armering, är hur partialkoefficienter används.

This literature study compiles available data and examines the potential environmental benefits of marine reuse and material recycling of fishery-related plastic waste at the Soten?s marine recycling center (M?VC). The marine environment faces significant challenges due to littering, where abandoned, lost, or otherwise discarded fishing gear constitutes a major source of both ghost fishing and plastic pollution. Through a literature review and analysis of the polymers polyethylene (PE), polypropylene (PP), and polyamide (PA), the study evaluates how circular resource management impacts fossil resource consumption and microplastic formation. Previous results show plastic materials in the marine environment gradually fragment into secondary microplastics through a combination of UV radiation and mechanical abrasion.

This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

En brandstation ställer specifika krav på funktionalitet och flöden - som i det här examensarbetet har fått generera rumsligheter och arkitektoniska händelser. Brandbilarna står uppradade i ett stort och rymligt garage. Ljuset flödar in genom portarna och det stora glastaket. Om hundrafemtio år kanske det inryms en konsthall här istället - så som i Magasin 3 en bit bort..

I en omv?rld d?r h?llbarhetsfr?gor f?r st?rre intresse ?r det av stor vikt f?r f?retag att l?gga ner resurser och tid p? att utveckla sina verksamheter h?llbart. ESG som st?r f?r ett f?retags arbete g?llande milj?-, social- och styrningsfr?gor har v?xt under senare ?r. Det har genom ?ren genomf?rts ett stort antal studier p? koppling mellan f?retags ESG-prestationer och deras finansiella prestationer som f?ljd, men resultaten ?r skilda och det finns inget tydligt konsensus inom ?mnet. I denna studie unders?ks sambandet mellan europeiska IT-f?retags ESG-betyg och deras finansiella prestationer.

The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.
