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.

Inverkan av försvagningar på bärförmåga för stålbalkar med långa spännvidder : En jämförelse mellan Eurokod och BKR

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.

Projektering av ett småhus med fördjupning i uppvärmningssystem

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Information per sträcka

Jag har låtit min yttre miljö vara en stark tongivare och låtit det förenas med mitt verk. Det mesta av mitt arbete har jag utfört i min egen verkstad. Det är en ateljé utformad runt en traditionellguldsmedsverkstad med de verktyg och material som hör till. Där har jag omgivit mig med bilder, material och föremål som intresserar mig.Resan och förflyttandet mellan HDK och min verkstad var min utgångspunkt. Det har jag dokumenterat och uttryckt i olika material..

Fjärrvärme - ny lokalisering av kraftvärme i Enköping

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

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).

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Vakuumisolering ? Ekonomiskt försvarbart för småhus?

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

?Matteboken, det är där man lär sig?eller? : En undersökning av lärares och elevers inställning till användandet av laborativt material i förskoleklassens matematikundervisning

Syftet med vår undersökning var att ta reda på hur läraren och eleverna ser på användandet av laborativt material i förskoleklassens matematikundervisning. Undersökningen genomfördes med hjälp av observationer och intervjuer av tre lärare och nio elever i samma kommun. Resultatet visar att lärarna och eleverna ser olika på användandet av laborativt material. Lärarna förhåller sig positiva till användandet och menar att de alltid har stöd av laborativt material i undervisningen. Eleverna däremot visar en osäkerhet kring syftet med användandet av materialen och har svårt att se det matematiska innehållet..

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.

En studie om vad tre klasslärare anser om laborativt arbetssätt i matematik

Syftet med detta examensarbete var att undersöka vad tre klasslärare för årskurs 1-3 anser om laborativt material i matematikundervisningen och hur de själva arbetar med detta i sin egen matematikundervisning. Detta undersöktes med hjälp av en kvalitativ studie med intervjuer och observationer. Observationerna användes för att se om det som lärarna ansåg om laborativt material speglades i deras undervisning. Med intervjuerna kunde vi ta reda på vad lärarna ansåg att det kan finnas för möjligheter och hinder med användandet av laborativt material i matematikundervisningen. Resultatet visar att lärarna överlag är positiva till användandet av laborativt material.
