Produktutveckling och prestandatest av ett vattenvärmedrivet torkskåp : Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med hjälp av UV-ljus och ozon

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

Selma Lagerlöf ? litterär mecenat och förmedlare av dialog : Gestaltning av läsarbreven och analys av författarfunktionen

At Kungliga Biblioteket in Stockholm you can find over 40 000 letters sent to Selma Lagerlöf. Many of her readers wrote and asked for her help, and the letters show that she helped a lot of people with money as well as with writing advice. People from all over the world asked her for money to be able to study, to finish their written works, or just to get through the day. Others want her to read their texts and poems, because they wish to hear her opinion or wonder if she can put in a good word for them at some publisher. This essay illuminates the question why so many people had this confidence in Selma Lagerlöf.

Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.

ÄTA-arbeten på Trafikverket

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

Sticklingsetablering av Sedum spp. för gröna tak : biokol som organiskt material i substrat

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

Verkbegreppet och bibliografiska relationer. En studie av gränsdragningen mellan olika verk med exempel från Dübensamlingen i Uppsala

The purpose of this thesis is to investigate the concept of a work and the problems with its definition and will also examine bibliographic relationships. The main question is what are the boundaries of a work and at what point a work becomes another. What is the meaning of the concept of a work within the context of the library? What are the solutions of bibliographic relationships and the concept of a work in KRS and FRBR? The thesis is based on a literature review. In the literature I have examined the discussions of the work and bibliographic relationships.

Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Båtbottenfärger innehållande TBTO : huvudsaklig källa till TBT i miljön

Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).
