The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

Begreppet hållbar utveckling har växt fram kring orsaker och lösningar för globala försörjnings- och deponeringskriser. Begreppet är mycket brett och diskuteras runt om i världen. Diskussionen om hur samhället ska uppnå en hållbar utveckling har påverkat fysisk planering och trafikplanering. Grunden till en hållbar utveckling ligger i en samordnad och miljöanpassad bebyggele- och trafikplanering. Det är bland annat viktigt att det finns förutsättningar för en effektiv och miljöanpassad kollektivtrafik och ett effektivt gång- och cykeltrafiknät.

The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

ABSTRACTThe purpose of this c-level essay shall try to illustrate how a good leader is formed. We have investigated what influences leadership style, personal characteristics or individual competence have when recruiting a new manager. This study has been carried out with comparative applications because we wanted to study the similarities and differences between the Unemployment Office, the Social Insurance Office and the Social Welfare Administration.We have used a qualitative method in interviews both with employers as well as the from the trade union representative?s perspective. Part of our results indicates that the trade union representatives and the employers are not always unanimous and do not request equivalent characteristics and knowledge at recruitment.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

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.

Title:?Varför går man inte hårdare fram? ? En studie i krigsorienterad journalistik av Public Service från Ukrainakonflikten?Authors:Cemil Arikan, Staffan Florén Sandberg and Karl Henrik OlssonSubject:Undergraduate research paper in journalism studies, Dept. of journalism, media and communication (JMG) Gothenburg UniversityTerm:Spring 2014Supervisor:Mathias Färdigh, JMG, Gothenburg UniversityPages/words:48 pages/16701 wordsPurpose:The main purpose of the paper was to examine if and to what extent the conflict coverage of two Swedish public service news programmes from the ongoing Ukrainian conflict could be said to orientate towards either war or peace journalism.Method:Quantitative and qualitative content analysisProcedure:News broadcasts from Rapport 19:30 and Dagens Eko kvart-i-fem, covering the Ukrainian conflict, over a period of two months, were analyzed from the normative perspective of Johan Galtung?s peace journalism theory and Wilhelm Kempf?s theory of war and peace discourse.Results:Both Rapport and Dagens Eko were found orientating towards war journalism. Reports were given, in a great extent, to events of violence and verbal threats.

Serpula lacrymans infestation has become an increasingly common problem, and is usually perceived as a tip of an iceberg.During the 21st century there has been a perceived increase of damage caused by serpula lacrymans, at AB Mats Fransson Saneringstjänst ? Anticimex in the county of Kronoberg. A similar increase has also been noted by employees at the offices in Kalmar, Karlstad, Piteå, Stockholm, Malmö, Söderhamn, Halmstad and Visby.The methods used to collect data for the project has been interviews with a number, for the project, relevant key persons, such as analysis engineers at Trygghansa and Anticimex, as well as personnel at the botanical institution at Gothenburg University and the Botaniska Analysgruppen in Gothenburg, further statistics from SMHI and analyses of reported instances of infestations have been used.The majority of the people interviewed believe that the increase is caused by renovations of old houses, higher precipitation during the summer months, as well as a moister climate and warmer winters. The latter can also be gleaned from statistics from SMHI concerning temperature, precipitation, and relative humidity.Analysed damage reports show that the most common cause for the infestation is ground moisture, even when combined wooden materials.Older houses that where built around 1900 are the ones most frequently infested with serpula lacrymans. The part of the building most frequently infested is the foundation, where cellars and suspended foundation are the most common types to be infested.

SummaryAt the start of my employment at the Swedish National social insurance office I was a bit confused because there were two categories which I defined as belonging to the same category (working handicapped) but it wasn?t so. The persons I where going to meet was defined as having incapacity to work and therefore, they were defined as not standing to the labour markets conversion. They were defined as being to sick for being at the labour market. The aim of this work is to shed light on what grounds a decision concerning a person which will be categorized as incapable of working and looking at the categorized person?s status.

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

I denna uppsats har länsstyrelsens tillämpning av riksintresse för kulturmiljövård studerats utifrån ett plan- och miljöparadigmsperspektiv. Den teoretiska utgångspunkten har varit paradigmbeskrivningen i Styrning av markanvändning och miljö (2006) av Lars Emmelin & Peggy Lerman (2006: 2,12-20). Teorin har tillämpats utifrån de lokal- och centralstyrningsaspekter som deskriptivt förklarar paradigmen. Avsikten har varit att studera hur plan- och miljöparadigmets styrningsprinciper kan identifieras i detaljplaneprocesser och hur dragen påverkar processerna. Dessutom har frågan hur länsstyrelsen ser på sin handläggning utefter lokal- och centralstyrningsaspekter varit en utgångspunkt för uppsatsen. Uppsatsen har utformats efter en fallstudieprincip.

The annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.
