Planning of a building project is very important for a successful execution. This will be the foundation of problems that will occur during the production. In the planning process people with different positions, search for the best suitable building methods.

Ekot från djupaste Afrika : En kritisk diskursanalys av nyhetsprogrammet Ekots gestaltning av konflikten i Goma, Demokratiska Republiken Kongo.

This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.

10-åring spårlöst borta : En studie om hur försvunna barn konstrueras i svensk press

The purpose of our study was to examine how missing children are portrayed in media. We wanted to see if there are any recurring story patterns and characters in the texts. We also wanted to examine how the relationship between children and adults are framed and which comprehensive view of children is mediated in journalistic texts.Our questions were: how do Swedish newspapers write about missing children? Which narrative pattern are there in the texts? How are children and adults represented in the texts? What relationship between children and adults are made visible in the texts? What a comprehensive approach to children is constructed in the texts?For this study, we used the media discourse, theories of representation, stereotypes and characters. And theories of narrative, dramatic turns and opposites.We chose to make three case studies in which children suddenly disappeared, the case of Bobby Äikiä, the case of Engla Höglund and the case of Sebastian Hedman.

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.

Prefabricerade Passivhus

European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.

The commission behind the project involved development of a machine that punches holes in packages for the inspection division at Tetra Pak. The task for the machine was to facilitate the process of making openings for testing in the company?s other equipment. Researches on different methods of cutting, types of automatization and possible designs were made. To implement the project a design and construction from the base where chosen.

En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion

Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in modern buildings. In modern contemporary construction, large glass panels are often the ideal because of increased light inflow and for architectural purposes. However, this can generate several negative effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that window shutters could have accommodated historically. This thesis identifies a lack of knowledge about interior window shutters in the Swedish building stock.

Ämnestransport med grundvatten i hydrogeologiska typmiljöer

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

"Månntro hon är homo?" : Om lesbiska kvinnors identitetsformering och livsvillkor 1950-1965

The construction of an identity among lesbian women during 1950-­?1965 is in focus in this master ?s thesis. My starting point is that identity, such as lesbian or any other identity, is formed in relation to other people and groups, as well as society. This thesis will also examine how lesbian women met and formed bonds with like-­minded, and whether these aspects changed, during the defined time period. The empirics is made up by letters written by women to Riksfo?rbundet fo?r sexuellt likabera?ttigande (a Swedish organisation for lesbian and gays) as well as an interview with two lesbian women who were born in 1938 and 1940.

BYGGBRANSCHENS MILJÖUTMANING ENLIGT PLATSCHEFER, ARBETSLEDARE OCH YRKESARBETARE: EN INTERVJUSTUDIE GJORD PÅ BYGG- OCH FASTIGHETSUTVECKLINGSBOLAGET NCC CONSTRUCTION SVERIGE AB

Byggsektorn står för en stor del av det totala avfallet i Sverige och står därmed inför stora miljöutmaningar. Däribland finns NCC Construction Sverige (nedan kallat NCC), Sveriges tredje största byggföretag med cirka 10 000 anställda. På varje bygg- eller anläggningsarbetsplats på NCC upprättas en miljöplan där olika krav omhändertas: lagkrav, lokala föreskrifter, beställarkrav samt interna krav.Studien genomfördes i samband med författarens praktik på NCC i Göteborg, avdelning Anläggning, med syftet att synliggöra yrkesarbetare, arbetsledare och platschefers syn på miljöarbetet på företaget - idag och historiskt. Totalt genomfördes 8 anonyma personintervjuer; två platschefer, två arbetsledare och fyra yrkesarbetare intervjuades under hösten 2014.Studien visade att ekonomiska incitament är viktiga för att miljöarbetet ska kännas berättigat för dem som utför det - framför allt för skeptikerna. Pappersbördan är hög och vissa anser att miljöarbetet enbart är en pappersprodukt utan egentlig mening.

Produktutveckling av klämskydd

Abstrakt Klämning mellan dörrblad och dörrkarm är en frekvent förekommande olyckstyp som drabbar såväl barn som vuxna i alla åldrar. I genomsnitt drabbas var fjärde svensk någon gång under sin livstid av så pass allvarliga skador till följd av klämning i dörr, att sjukhusvård krävs. Som regel är det handens fingrar som skadas. På marknaden finns ett stort utbud av tekniska lösningar som i någon mån syftar till att förhindra klämskador i kontakt med dörrar. Dock är de flesta av dessa lösningar utformade för dörrens gångjärnssida. För dörrbladets låssida existerar inget klämskydd som kan göra anspråk på att vara heltäckande.
