I Sverige används det idag cirka 5,4% förnybara drivmedel inom transportsektorn, att jämföra med under 0,5% år 2000. Av de ickefossila drivmedlen är el något som ofta benämns som en permanent och realistisk framtida lösning. Visionen ?Stockholm ? Elbilsstad 2030? drivs av Stockholms Stad i samarbete med Fortum AB i syfte att ersätta den fossilbränsleslukande fordonsflottan.I den här studien undersöks de tekniska förutsättningarna och de eventuella vinsterna av ett storskaligt införande av elbilar. Studien har gjorts genom en modellering där parametrar som elbilens prestanda, elpris, bilens inköpspris och totala utsläpp använts.

There was a silence surrounding homosexuality in the People's Republic of Poland. One can almost get the impression that same sex love, and same sex relationships, did not even exist there; that the communists had successfully removed homosexuality from society. The roots of this silence can be found in the Communist Party´s disdain for anything deemed individualist and deviant, and also in the conservatism and religiosity of the Polish society.In my thesis I study when and how gays and lesbians found a way out of the silence that surrounded their sexuality. Gay men did so by creating subcultures, which found refuge in parks, public bathrooms and a few bars in larger Polish Cities, and offered a sense of belonging for them. Lesbians, on the other hand, lacked this access to semi-public spheres, which made it even harder for them to find each other and create a space for their sexuality.

Background:Investments in different forms have always been popular to every human being. For the most common investments, such as stocks and bonds, there are loads of information to gather for the investor. Historical data like risk, return, dividends and fundamental data like annual reports are often very easy to find, regarding these kinds of investments. The background of this thesis is the lack of market information in residential real estate investments. A problem with this investment is that there is lack of information regarding risk adjusted return for real estates, which this thesis intends to present.Objective:The objective with this thesis is to study which alternative, directly-owned residential estates or stocks, who generates the highest risk adjusted return.

The study's starting point is the cultural, economic, social and health which is relevant when different levels of society affirms. The aim has been the basis of the representation levels of society discern what is valued and given priority as well as the measures and the strategies used in implementation. The empirical data underlying the study is qualitative studies with respondents from a university, a hospital, a school, the Swedish Embassy and an organization in order to create an image of different levels in society means to implement preventive measures on HIV and AIDS to their citizens. The result demonstrates that there are clear shortcomings in its implementation guidance on prevention measures for HIV and AIDS as lack of resources is based.

Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the Cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.

This project explores how artificial landscapes as parks and squares above ground can save space by using the vertical voids in urban environments and how they can create spatial and social as well as ecological qualities and connections. Hybrid landscapes are a phenomenon of current interest within the field of architecture and urbanism. Architecture as surface, where facades and roofs become possible to tread, is a relatively recent occurence that has over the past few years become an increasingly common sight in architectural magazines and on international architecture exhibitions. Many of my selected reference projects have often been associated with sensational contemporary design trends generated by advanced computer software. But the phenomenon is also a result of other different currents of change that exist within today?s society, such as densified Cities with a lack of open space, which is also expressed in architecture.

All over the world the waste from human society is causing problems. In developing countries, large Cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

For years the northern parts of Sweden, Norrland (translated: North land) has been considered mystified and exotified by the southern, more urban parts of the country. The rural Norrland ? though 60 percent of Sweden ? is seldom a part of the common conversation, meaning that most of the people living in the southern parts simply have no idea what is happening in the north. The one million people living in Norrland, on the other hand, every day gets to know what happens in the south on the evening news. The question about this possible structural relation between the urban and the rural became a large matter of cultural debate in the spring of 2015, If this thesis is true, we have a problem on our hands; can the national news be considered national if half the country is misrepresented? That question is what this essay is trying to find out by analyzing two of Swedens largest national newspapers.

The aim with my research is to illuminate the meaning of IKEAs settle in Haparanda, for the region Haparanda-Tornio, its economic growth and its inhabitants. The research has been carried out only through qualitative methods. Some interviews with a range of people from varying companies have been conducted.Haparanda is a smaller Swedish city situated in the north, on the border to Finland and to a city called Tornio. These two Cities, Haparanda and Tornio, has realised they are stronger in pairs, so they initiated cooperation across the border. Haparanda-Tornio is not a region of historically welfare and well-being.

Newly built urban environments are a prominent feature of contemporary Swedish Cities, yet are often experienced as anonymous and difficult to feel belonging to. This study examined which physical and aesthetic characteristics of newly built urban environments in Gothenburg co-vary with experiences of placelessness, how these experiences vary between different types of urban environments, and how they relate to individuals' attachment to the city.The study was based on a quantitative survey of 98 respondents, distributed through Gothenburg-oriented groups on social media. Respondents assessed photographs of four newly built urban environments: Kvilleb?cken, Masthuggskajen, Fixfabriken and G?taverken using a placelessness index derived from six statements on a five-point Likert scale. The physical and aesthetic characteristics of each area were coded by the researcher along three dimensions: scale, level of detail, and compositional order.

Stockholm is one of the fastest growing Cities in the world. Its population is growing every day and the housing needs are becoming higher. Despite the growth and the need for more houses only a few new housing units are being built every year. Critics argue that if the building rate stays as it is today the development of the city will be very limited since there is no capacity for the city to embrace new incomers.The decision makers in the municipality of Stockholm are planning for large investments in housing units for the coming years up until 2030. There are plans of building approximately 140 000 new apartments to mend the ascending need for new houses.Farsta County is part of Stockholm and lies a few kilometers to the south of the city center.

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the Cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of Cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control.

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in Cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Road safety is the result of measures to reduce therisk of accident and injury. (Nationalencyklopedin,2008). In principle, road safety means to arrive saveand sound.Safe traffic in Cities is mainly achieved throughappropriate speed. In Sweden, more than half ofall rides happen with a speed above the legal speedlimit (Holmberg, Hydén m.fl, 1996). To reducespeed in order to increase safety requires measureswhich influence a driver?s motives for his orher choice of speed even if these are not rational(Boverket, 2002).
