Urban vindkraft i Liljeholmskajen
Stockholm, Sveriges huvudstad blev framröstad som Europas miljöstad och en vision är att öka elproduktionen av vindkraft från ca 3 TWh/år till 30 TWh/år på 10 år vilket är en markant ökning. Detta medför installation av många vindkraftverk, både i stora fria ytor men även i urbana miljöer. Många delar av centrala Stockholm är under utveckling, där vissa stadsdelar ligger mer strategiskt än andra och här bör man utnyttja vindförhållandena maximalt.Rapportens syfte är att undersöka om förutsättningarna för installation av småskalig vindkraftfinns i Liljeholmskajen, söder om Stockholm. För att avgöra om förutsättningarna finns har elproduktionen för två vindkraftsmodeller kartlagts och en socialundersökning i området genomförts. Vidare har olika användningsområden utretts.De undersökta modellerna har visat en årlig på produktion på 13,4 MWh respektive 25,8 MWh, och den maximala ljudnivån som uppfattas ligger under den tillåtna gränsen i stadsmiljö.
Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
Att fånga flödet i kollektivtrafiken : En jämförelse mellan handelsplatser i Hong Kongs och Stockholms tunnelbana
The retail sector is in a continuous development. What demand looks like and where the consumers want to shop has changed during the last years. Market place, demand, supply, external factors and politics affect how the retail sector develops. To make a market place attractive a variety of factors have to be considered.In Hong Kong a model called Rail & Property is used, this means that the development of the subway is integrated with the development of the city. The model is both successful and economically sustainable.Today the supply of shops and services in Stockholm´s subway stations is rather small.
Jakten på värde: ? En kvantitativ studie om upplevt kundvärde och nöjdhet vid bostadsrättsköp i Stockholms innerstad
This Master Thesis within Marketing and Strategy investigates the values customers perceive within the Real Estate market in the inner City of Stockholm. The dependent variable is customer satisfaction, and it could be explained by 1) the feeling of light and uniqueness of the apartment, 2) that the apartment is of a satisfying size, 3) the address of the apartment, 4) and the economics, the common areas of the building, and the bidding process. The feeling of light and uniqueness, combined with the number of square meters, and the monthly fee of the apartment, are also identified as the price driven functions of this market. A quantitative method is used to investigate the market, where 107 apartment buyers completed a survey..
Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län
During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.
Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :
Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.
IMO:s barlastkonventions konsekvenser för sjöfarten inom Östersjön
Arbetet behandlade vilka konsekvenser inom driften (ekonomiska kostnader och teknologi) som rederier kommer att drabbas av när IMO:s barlastkonvention träder i kraft då barlastvattnet måste renas innan inträde i Östersjön. Arbetets syfte var att få fram vilka konsekvenser det blir för rederier när IMO:s barlastkonvention träder i kraft. Resultatet skulle jämföra skillnaden mellan lag och rekommendation då Helsingforskonventionens rekommendationer baseras på IMO:s barlastkonventions krav. En kvalitativ metod valdes för att komma fram till resultatet, i form av en öppen intervjustudie, där fyra olika företag har intervjuats. Syftet med intervjuerna var att se ifall de följde Helsingforskonventionens rekommendationer och vilka konsekvenser det skulle innebära och skulle komma att krävas då Barlastkonventionen träder i kraft.
Ägarlägenheter : En möjlighet till införandet av en ny affärsmodell?
This thesis will explore how swedish Talang 2010 used their strategic communication in Kalmar and Stockholm and how the effect of this work was shown in the two cities. With a focus on how the sender was working with the external communication in the two cities, the heart of the research was studying Talang 2010?s communication strategy in these two contexts. The research was made with surveys during two audition days in Kalmar and two days in Stockholm. The competitors, the audience and the general public were answering different surveys but with the same base to study the effect.
Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten
In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.
Ett socialt Dream Team : En studie om manlig identitet och meningsskapande i Stockholm Konstsim Herr
Stockholm Konstsim Herr har tills nyligen varit det enda manliga konstsimlag i Sverige. Och är ett av få i världen. I April 2011 vann de sitt andra guld i rad i tävlingen Men?s Cup, den enda tävlingen för manliga konstsimlag.Jag har i den här uppsatsen velat undersöka hur och i vilken mån deltagarna i laget upplever konstsimmet som meningsskapande och hur de konstruerar, gestaltar och skapar en manlig identitet i och genom konstsimmet.Jag har gått till väga så att jag har gjort några intervjuer och deltagande observationer, och i kombination med utvald teori byggt min analys på det.Centrala begrepp är maskulinitet, meningsskapande, identitet, hegemoni och tabu. .
Dynamisk massbalansmodellering av fosfor i Östersjön
During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.
Idiopatisk cystit hos katt : en retrospektiv studie
Lower urinary tract diseases are a common problem in cats all over the world. The symptoms are for example dysuria, pollakuria, stranguria, periuria and hematuria. In approximately two thirds of these cats the underlying cause is not known and the disease is therefore called feline idiopathic cystitis (FIC). We need to know more about the disease to get a consistently effective treatment and prevention.
A retrospective study was performed in 50 cats with symptoms of FIC and where other causes of inflammation were ruled out. Data like breed, age, sex, body weight, feeding, therapy and therapeutic results were collected, also if it was an indoor or outdoor cat, duration of the symptoms, if there was any stress and if the cat was living with another cat.
Spårning av miljöstörande ämnen i Uppsala stads spillvattennät
To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.
Spårvägskonstruktioner : Underlätta valet av spårvägskonstruktion
Stockholms spårvägar växer i allt snabbare fart, och det är allt fler kommuner som är intresserade av den typen av transportmedel. Något som idag är en brist inom spårvägsindustrin i Stockholm är kunskap och erfarenhet om spårvägsämnet. Drift och underhåll har varit minimal eftersom det inte har prioriterats sedan Tvärbanan öppnades. Detta har lett till för tidig reinvestering av gatuspår i mångmiljonbelopp.Då det förekommer olika förutsättningar som måste tas hänsyn till i form av buller, mån om plats och geoteknik finns det många konstruktioner att välja mellan när en spårväg ska byggas. Denna rapport har som syfte att underlätta val av spårvägsinvesteringar i framtiden.
