Verksam i betydande omfattning : Analys utifrån "vanliga anställdas" perspektiv i personalägda företag
Denna uppsats inriktar sig på rekvisitet verksam i betydande omfattning (verksamhetsrekvisitet) i relation till ?vanliga anställda? i personalägda fåmansföretag. Det framgår i förarbetena att verksamhetsrekvisitet anses vara uppfyllt när delägarens arbetsinsatser har stor betydelse för vinstgenereringen. Den avgörande faktorn här är om delägaren genom arbetsinsatser genererat intäkter till företaget. Arbetsinsatser av ?vanliga anställda?, dvs.

Charlie don't surf! : En studie av det postkoloniala perspektivet i amerikanska Vietnamkrigsfilmer
Syftet med denna studie är att i sex amerikanska filmer som tar upp kriget i Vietnam undersöka hur den västerländska och den orientaliska kulturen skildras i relation till varandra utifrån ett postkolonialt perspektiv. Både framställningen av såväl amerikanerna, fienden och sydvietnameserna har studerats ur detta perspektiv. Detta undersöks genom att koppla till teorier och begrepp såsom semiotik och ideologi och metoder såsom diskurs och diskursanalys, mise-en-scéne och filmanalys. Studien undersöker om det skett någon förändring av det postkoloniala perspektivet i filmernas framställning. Undersökningen inkluderar: Gröna Baskrarna, The Deer Hunter, Apocalypse Now Redux, Plutonen, Full Metal Jacket och We Were Soldiers.

?Halmstads Fastighets AB? is a local real estate company investing in sustainable development. One problem though is that the domestic waste, particularly the source separation, at the three resident blocks for students? isn´t working very well. This creates inconveniences for people and environment as well as decreasing the impression on the estates.This project has had the ambition to improve the domestic waste and increase the amount of source separation at HFAB´s student hostels.
Implementation av CUSUM/SPRT-algoritm för kvalitetsövervakning i realtid av robotsvetsning
Under början av 1990-talet inledde Volvo Personvagnar i Olofström en process där övervakning av robotiserad MIG/MAG-svetsning var i fokus. Det ledde fram till ett forskningsprojekt som resulterade i att Stefan Adolfsson, Lunds tekniska högskola/Blekinge tekniska högskola, 1998 presenterade avhandlingen Automatic Quality Monitoring in GMA Welding using Signal Processing Methods [5]. I den presenterades ett SPRT-baserat övervakningskoncept för övervakning av MIG/MAG-svetsning med kort- och spraybåge. För att få fram ett kostnadseffektivt övervakningssystem uppkom tanken att använda vanliga PC-datorer som plattform. De erbjuder hög beräkningskapacitet till förhållandevis låg kostnad.
Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär
The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
Stadsplaneringsideal. Med den periurbana zonen i fokus - dess potential för den hållbara staden
To be able to plan for the expansion of a town, one needs a vision of the future appear-ance of the town. It is the current issues (social situation, supply and demand, political control etc.) which decide what the ideal for town planning is. This is turn is the steering factor of the physical structure of the town. Therefore, the town's structure is decided by these ideals.In this report, I will present planning ideals that have historically been, and which criticisms that have been directed towards them. With reference to these issues, I will present those guidelines and ideals we have today for planning of our towns.
Hållbar och framgångsrik? : samband mellan hållbarhetsprestanda och finansiella aspekter i börsföretag
Many companies have historically forced their interests through without any thoughts about the future needs of the humans and the society. In the last few years voices have been raised for a change, companies need to take their responsibility regarding sustainable development.The purpose of the report is to describe and explain possible relations between sustainabil-ity performance of companies and profitability, valuation, industry and size respectively.To be able to judge the sustainability performance of the companies Folksam (2006a) have been used. This is a solid investigation of the companies listed on the A- and O-lists of the Stockholm Stock Exchange by the end of 2005. The sustainability marks have been com-pared with the chosen key values for each hypothesis respectively. With this quantitative data as foundation, a quantitative approach and a deductive method have been used.In the first area of the investigation, profitability, the authors found correlation for the main hypothesis between sustainability performance and ?Return on Total Assets? through a statistical test.
Utveckling av ett lyftverktyg för skivformade produkter
Under höstterminen 2013 har Stefan Erlandsson och Louise Andersson, designingenjörsstudenter på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med entreprenören Lars Willebrand. Målsättningen för projektet var att utveckla ett lyftverktyg som ska komplettera Willebrands produktserie bestående av; travers, svängkran, plåtbyrå och lyftverktyg. Lyftverktyget ska vara anpassat för att användas i kombination med en plåtbyrå, vilket innebär att det kommer användas till att lyfta material från höga och låga höjder. Lyftverktyget måste därmed konstrueras i syfte att underlätta för användaren och undvika arbetsskador som kan uppstå vid dessa lyft. Lyftverktyget ska även kunna anpassas till kunder som endast avser att lyfta skivformade produkter i midjehöjd.Projektet inleds med en förstudie där mycket fokus läggs på ergonomi och användaren.
Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial
Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality
Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.
Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG
This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.
