Analys av miljömedvetenhet under produktionsprocessen
NCC Construction är en del av NCC koncernen och är ett av de största byggföretagen i Sverige idag. Detta examensarbete är utfört i samarbete med NCC Construction i Karlstad och behandlar ämnet miljömedvetenhet. Uppgiften var att studera och analysera de anställda med hänsyn till deras miljöpolicy samt att uppskatta hur väl företaget når ut med sin information, samt att ta fram olika förslag på förbättringar i NCCs pågående miljöarbete.NCCs miljöpolicy har fyra övergripande mål och det finns klart och tydligt nerskrivet vad den anställde är skyldig att bidra med i sitt arbete med hänsyn till företagets strävan mot en bättre miljö. Behovet av en väl formulerad miljöpolicy är väsentligt då det är denna som beskriver vilka mål som finns och hur dessa ska uppnås.För att få fram svar på min frågeställning utfördes en enkätundersökning där arbetsledning, byggnadsarbetare samt underentreprenörer var målgruppen. Denna undersökning var anonym och analyserades med hänsyn till position, ålder och antal år i företaget.Resultatet i denna undersökning visar på stor förståelse hos de anställda inför miljöfrågor.

Bättre enskilda avlopp i Sigtuna kommun : möjligheter för bebyggelse i Odensala socken
There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010.
A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.
Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.
Target Costing i produktutvecklingsprocessen : En studie på Volvo Construction Equipment i Braås
Bakgrund: Produktutvecklingsprocessen har på senare tid kommit att ses som en strategisk aktivitet som är avgörande för företagets överlevnad eftersom produktens utförande och kostnader till stor del fastställs innan tillverkning påbörjas. ?Target Costing? har sitt ursprung från Toyota i Japan och är en metod för strategisk kostnadsstyrning som har vuxit fram för att tidigt styra kostnader. Metoden används för att integrera kostnadsstyrning i produktutvecklingsprocessen i samstämmighet med kundkrav och företagets egna vinstkrav.Syfte: Syftet med studien är att beskriva och analysera hur ?Target Costing? används i produktutvecklingsprocessen på Volvo Construction Equipment i Braås för att ge kunskap till nya potentiella användare.
Ebbas klänning Uppmätning och analys som källa till information i kombination med historisk undersökning
This study focuses on costume as a source of information. By making a case study of an 1880's dress itaims to explore the conservators potential as an investigator and conveyor of the information containedin a costume. Further explanation of this role is made by reference to several statements made by wellknown textile conservators. The paper also explores the different words used to make a new version ofa preserved or inexistant garment, gives an extensive presentation of taking patterns and an insight tothe other methods used for analysing costumes. The case study consists of an investigation of the dressconstruction, during which a pattern is taken, and a literature study of the contemporary fashion, theowner of the dress and the maker of the dress.
Passivhus, detaljutformning och dess köldbryggor
Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.
Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor
Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. Detta lämnade stora ytor av Borneos skogar i ett undermåligt, sekundärt tillstånd. På grund av detta startades INIKEA projektet med syfte att rehabilitera skogar i regionen kring Tawau vid östkusten av delstaten Sabah i Malaysia. I denna studie undersökte jag resultatet av rehabiliteringsarbetet på krontaket i tre olika skogstyper genom att ta hemisfäriska foton med en digital systemkamera (DSLR).

Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Relationen mellan utformningen av digitala bibliotek och användarnas behov. En intervjustudie vid Göteborgs universitets digitala bibliotek.
The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.
Klistret i klustret : En undersökande studie av ansamlingen av GIS-relaterad verksamhet i Gävleregionen
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
