Det uppätna monopolet : Initiativ, inflytande och resurser vid planeringen av kvarteret Druvan genom projektet Mitt I City
The purpose of this essay is to examine if the municipality has a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project.In Karlstad there is now (2006) a large building project in form of a shopping mall. This project is in its final stage of completion and offers me a suitable case to examine. To undertake the purpose of the essay, the following research question is formulated:Do the municipality have a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project as the Mitt I City project?In an attempt to examine the project and the planning process, three themes are applied. The first theme derives from the hypothesis that the part that initiate the process gets the upper hand as future discussions are taking place in relation to the original ideas.
Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?
Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.
Design and evaluation of an AGV-system for Tetra Pack in Lund using simulation
This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.
Skolans utformning, ett hinder för lärares eget lärande? : En studie av den fysiska arbetsmiljöns påverkan på lärares eget lärande
This essay is written about how the physical environment affects teachers? own learning. The purpose is to see how the teachers? work is affected by various factors, such as the uses and placement of the teachers? offices, common room, or any other places where a meeting may occur. The survey was conducted using both interviews and observations of the teacher?s office.
Att låta tusen blommor blomma. - Lärares syn på relationens betydelse för elever med koncentrationssvårigheter.
The aim of this bachelor's thesis is to investigate how teachers view the way they build their relationships towards students, both in general and, more specifically, towards those students with some type of attention deficits. The focus of this thesis has been on how great an importance teachers place on this relationship. Especially when it comes to working with students with attention deficits. We also want to know to which extent this relational perspective is rooted in teachers' practice. The theoretical basis of this study is the relational perspective formulated by Aspelin and Persson (2011).
Miljöcertifiering av ett byggnadsminne
Samtidigt som debatten kring jordens klimatförändring är i full gång har intresset för att miljöcertifiera byggnader vuxit oerhört. För fastighetsägare är det en möjlighet att bevisa för sina hyresgäster och köpare att byggnaden är hållbar. Är en byggnad miljöcertifierad har en oberoende part intygat att den uppfyller en nivå av hållbarhet som bestäms utifrån standardiserade kriterier. Fastighetsägaren kan alltså använda certifikatet i marknadsföringssyfte.Den här studien undersökte om en byggnad som är byggnadsminnesförklarad kan miljöcertifieras med Miljöbyggnad. Målet var att hitta kostnadseffektiva lösningar för att uppfylla de miljöcertifieringskriterier som eventuellt inte uppfylls idag.
En skattemyndighet : Balans mellan maktutövning och relationsbyggande
Background: Power by force and threats used to be the common way to collect taxes, but this procedure is today completely different. It?s now more about building a mutual relationship and with help of laws and controls steer citizens and companies to pay the tax they owe. Thus the way to collect taxes have changed over the years, the collecting of taxes aren?t a popular task to do.
Till en älskad vän : materia och objekt som medier för överföring
With self-hypnosis as a method, I work with levels of consciousness in relation to practice. Focus lies in the relation between a language of materials and an inner experience. How do material expressions function as mediums of a spiritual matter between a beholder and me? The trance functions as a space for a spiritual contact/communication. Abstract images of crystalline glaze on ceramic tiles are direct results of these acts.
Expansionsmaskiner istället för strypventiler - en effektivisering
In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.
Energieffektiv projektering : Projektering för ett träffsäkert och energieffektivt slutresultat
Byggnadssektorn uppskattas idag stå för närmare 40 % av vår totala energiförbrukning, varav nästan 60 % utgörs av uppvärmning och varmvatten. Från myndigheter såväl som allmänheten börjar högre krav ställas på energihushållning i vårt byggnadsbestånd. I media duggar informationen tätt om nya metoder för energieffektivisering, ändå visar statistiken att mycket finns kvar att göra. Frågan som bör ställas är var problemet ligger.Detta examensarbete behandlar projekteringens roll för slutresultatet med avseende på energianvändningen i flerbostadshus. Syftet är att identifiera förbättringsfaktorer för hur projekteringen kan påverka byggprocessen mot ett mer energieffektivt slutresultat.
Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen
A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.
Kv. Draken : En studie i kostnadseffektivt byggande
Den bostadspolitik som förts de senaste två decennierna har gett oss en alltmer segregerad stadskärna i Stockholm. Byggsubventionernas avveckling på 90-talet har lett till en historiskt låg byggtakt och ett byggande som ensidigt riktat sig till resursstarka grupper i samhället.Parallellt med detta har stora delar av hyresbeståndet ombildats till bostadsrätter vilket medfört att många relativt billiga hyreslägenheter i äldre fastigheter har försvunnit ur beståndet. Dessa är svåra att ersätta med nyproduktion, då dessa är dyrare.Kärnproblemet är förstås att det är dyrt att bygga hus och om man antar att den nuvarande bostadspolitiken består är det ytterst angeläget att utveckla kostnadseffektiva byggmetoder för att möjliggöra lägenheter med överkomliga hyror som kan bidra till att motverka boendesegregationen på sikt.Vårt förslag består av ett bostadshus i Stadshagen. Fastigheten är indelad i två byggnadskroppar som länkas samman via ett system av loftgångar kopplade till ett trapphus. Husen är uppbyggda av volymelement som staplats på en platsgjuten sockel.
Rätt gåva för rätt tillfälle
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
Internationell Upphandling av Byggmaterial : En studie över materialimportens potentiella tillämpning hos medelstora och stora byggentreprenörer
High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.
