Solenergi på Nordvästra Kungsholmen
The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.
Bruka utan att förbruka - när andra intressen än ekonomin får styra
To have a forest area close to the city is of great importance for the city population?s well being. Children develop their motor skills, concentration and imagina-tion and the adults have a place to shake of the stress from work. Forest areas are used to exercise at, play in and to find a moment of peace and silence.
The urban forest and the old farming pastures at Markussonvallen and Per-Isakssonvallen already has natural assets worth to preserve and a great potential to create more. The goal is to develop a forest with a variation of tree species and ground vegetation that will appeal to the human senses and different animal species such as birds, insects etc.
Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?
Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Mångfunktionella golfbanor : rekreativa och pedagogiska platser
The objective of this essay is, from the golf perspective including the golf courses' physical attributes, golf club management, members of the golf club and golf course designers, to explore possibilities for making existing golf courses more multifunctional. The purpose of this is to increase the understanding for golf courses' role as part of the landscape and comprehension regarding possible opportunities around them to exploit and develop.The increased pressure of population in peri-urban areas has resulted in a greater need for accessible recreation, particularly in the isolated farmland. As a result, land is sometimes used against landowners' will, which is a deficiency that is the basis for many conflicts between farmers and landowners.In the current situation, there is a negative trend in golf with reduced interest and fewer golfers than in the past. As a result, many of Sweden's golf courses have financial problems and are therefore trying to find new ways to avoid bankruptcy. Sweden's existing golf courses occupy about 30 000 hectares of land, of which a very large percentage are located in peri-urban areas.
Utlakning av tungmetaller från Skörby deponi
The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.
Dialog om staden : En studie om medborgardialogens roll och betydelse för stadsplaneringen i Nacka kommun
This master thesis explores the nature of public participation as a central and most current subject in the field of urban planning. A first impression exposes a seemingly unanalyzed consensus on the values and benefits which public participation provides the process of urban planning. The city may be a concern to all its inhabitants; hence knowledge and opinions of the local public are of great importance for the urban development. But is there really something new to these assumptions, and are the advantages of increased public participation in urban planning always obvious? By using action research as a main method, I have put myself into the context of the Swedish municipality of Nacka and their projects dealing with the development of public participation.
Mind the gap : the possibilities of the public space in the contemporary city
Mind the gap encourages you to beware of the interspaces. The project seeks to
defend the gaps that occur in time and space and encourages the reader to care
about the interruptions of the routine-like and planned, whilst also opening up a
discussion about interaction and participation. Mind the gap is a project about the many
opportunities the public space has in the contemporary city. What you have in front of
you is the result of this project.
As society constantly changes, new and different needs arise in the city and it is
necessary that architects and planners understand and adapt to these changes.
They have to be able to develop new ways of thinking and to challenge established
perceptions of what the public space is and should be. This means being able to see
that the public space could be different and to recognize the potentials for it to change.
This project examines the underlying ideals of urbanism and investigates
the potentials of the City when shaped by these ideals.

Transformerat stadsrum : öppnar upp och länkar samman
Mitt syfte med projektet är att vitalisera stadsdelen Husby i nordvästra Stockholm. Bryta upp zonerade områden och addera fler och varierade funktioner som definierar nya stråk, länka samman omtyckta områden och överbrygga platser som upplevs otrygga. Sammantaget ger det förutsättningar för ett mer levande stadsliv som attraherar fler att vilja bo, bo kvar och göra bostadskarriär i Husby.Centrala begrepp i projektet är mångfald, trygghet, flexibilitet och hållbarhet. Jag har arbetat med att identifiera, bevara och utveckla kvaliteter i kombination med att öppna upp befintlig bebyggelse som präglas av upprepning, slutenhet och rationella byggmetoder samt addera ny bebyggelse för att få en större mångfald och ett mer flexibelt utbud av både lokaler, bokaler och bostäder men även genom att analysera och bearbeta områdets struktur. Fokus har legat på de trafikseparerade miljöerna och hur de kan vidareutvecklas genom att bland annat addera gångvägar och skapa nya stråk längst tillfartsgatorna och samtidigt bevara kvaliteter som de nivåseparerade korsningarna mellan gångvägarna och bilvägarna erbjuder med säker skolväg och en trygg bilfri miljö för barnen..
Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige
In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable
concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population
consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas.
Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.
Ett sökande efter stadsideal : En fallstudie om stadsideal i Karlstad
This study shows how city planners and politicians in Karlstad plans different parts of the city, what type of model/ city ideals they use when planning, and how it is expressed. The study was made using a qualitative method, were a discourse analysis was vital for the elected planning document and blog posts. Qualitative interviews were also made with five people with significant meaning, who hold different positions in the city planning of Karlstad. In the produced material, it appears that the city planners and politicians in Karlstad are planning for traditional city ideals as a foundation in the planning, with influence from new ideas as for example sustainable planning and economic growth. In some parts of the city a modern and rational planning remains.
Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus
In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.
Validation of Steins/Arla Foods method for lactate fermenting clostridia in milk
One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.
Varför odla i staden? : En kvalitativ intervjustudie om urban odling utförd i Uppsala
SammanfattningSyfte Studiens syfte är att undersöka friluftsundervisningen i grundskolor med friluftsprofil i Oslo och Stockholm, samt jämföra dessa.Vilken eller vilka stilar av friluftsliv förekommer inom idrottsämnet i friluftsprofilerade grundskolor i Oslos kommun?Vilken eller vilka stilar av friluftsliv förekommer inom idrottsämnet i friluftsprofilerade grundskolor i Stockholms kommun?Vad kan vi se för likheter eller skillnader mellan skolorna i Oslo och Stockholm?Kort sammanfattning av Sandells friluftsstilar:Passiv anpassnignsstil: friluftsliv utifrån ett anpassat betraktande perspektiv utan att påverka naturen.Aktiv anpassningsstil: friluftsliv utifrån ett aktivt perspektiv där du lever av naturen och tar vad du behöver samtidigt som man värnar om naturen.Dominant anpasssningsstil: friluftsliv utifrån ett aktivitetscentrerat perspektiv där ofta kommersialism styr för att påverka och anpassa naturen för att ge rum för specifik aktivitet.MetodAnvänd metod är öppet strukturerade telefonintervjuer. Sex stycken idrottslärare, tre i Oslo och tre i Stockholm intervjuades varav två var kvinnor och fyra var män. Samtliga var utbildade till idrottslärare eller lärare med undevisning inom friluftsliv.ResultatAlla stilar förekommer i Oslo. I Stockholm råder tveksamhet kring den dominansstilen.
