?ÄNTLIGEN!?- En lysrörsarmatur för det egna hemmet

The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.

Hackerör på Sydsvenska höglandet : vad skiljer röjningsröseområden från celtic fields, stensträngsområden och bandparcellområden?

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.

Alter ego : Ett föränderligt bord

Projektet har gått ut på att göra ett flexibelt bord som ska kunna gå att förändra mellan högt och lågt och mellan olika storlekar på bordsskivan. Detta som en funktionell aspekt av föränderlighet men jag ville även införliva en emotionell föränderlighet. Jag vill att användaren, på ett handgripligt sätt, ska kunna uttrycka sig själv i bordet. Min intention är att man, genom att göra sitt eget unika bord, skapar ett starkare band mellan artefakt och dess användare. Detta som ett led i en hållbar utveckling så att produkterna vi äger kan brukas längre och motverka den ohållbara så kallade slit-och-slängkulturen..

Energi- och kostnadseffektiva klimatskal : För lager-, industri- och kontorsbyggnader

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

Projekt Sunbaker : Utveckling av en solugn för bakning, en fältstudie i Namibia

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam

In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status. The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.

Dubbeltydig form : Djurliknande avbildningar i metall under järnåldern

This study concerns a selection of prehistoric metal objects of animalistic design, published at the internet site of the Swedish Statens Historiska Museum. It seeks to give an impression of the design elements used, and to find likely models for the motifs among live animals. The method used is a qualitative hermenuetic comparative study of objects, where the distinct significant design elements are being identified and interpretated. Several significant design elements are identified, and some are interpretated as representing certain animals. The amalgamation of differentiating design elements in some objects however, leads to interpretations of compound animal motifs, where some motifs are considered ambiguous and some are rendered uninterpretated.

Onstage/offstage : - om avvikande och normbrytande.

Den här uppsatsen tar avstamp i en personlig erfarenhet av när representationen på sociala medierorsakat konsekvenser i den fysiska världen. Uppsatsen undersöker, genom en autoetnografiskmetod, processer för normerande tillhörighet inom speciella diskurser. I texten användsmusikgenren Black Metal som exempel för att visa hur normer styr och kontrollerar socialthandlingsutrymme för kvinnor. Begrepp som används för att beskriva dessa processer kommer frånErving Goffman och har kallats för det dramaturgiska perspektivet. Begreppen används vidare iarbetet som verktyg i det gestaltande arbetet där normer för subjektspositioner undersöks iiscensatta fotografier..

Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Granproduktion på tallmarker! : är produktionen hållbar?

The aim of this report was to investigate the hypothesis that Norway spruce (Picea abies L. Karst), planted on poor ?Scots pine? stands will not have sustained growth during the whole rotation, due to water deficit in the closed stands. In order to investigate this hypothesis, data from 10 Norway spruce stands in southern-eastern Sweden were collected. In 10 plots in each stand, diameter and breast heights were measured on every tree.

Gravar i Alsike hage : Analys av fyndkontexter och gravkonstruktioner tillhörande gravfältet RAÄ 26 i Alsike socken, Uppland

This essay deals with the results and observations made during excavations in an iron age cemetery in Alsike hage, located in Alsike parish. The excavations took place in 2005 and 2006 and the investigated area comprised two adjacent, but secluded burial-constructions; a square stone setting with a secondary grave, and a stone-built terrace with at least one secondary grave. The artifacts suggests that the TPQ of the stone setting, and the construction date of the rest of the graves, is 900-950 A.D. The aim of this study was to comprehend the course of events in the investigated area, and toanalyse the archaeological finds - in comparison to the well documented an discussed material burial culture in the lake Mälar area ? in order to discuss indicators of gender and social status.Metal artefacts has been preserved as a part of the analysis..

Kunskapsfabrikens rötter

The purpose of this study was to investigate, through a qualitative survey, the need of knowledge and strategy in organisations today and tomorrow. The empirical investigation is built on a semi structured interview that was conducted on nine different companies in Gislaveds community. The companies were from three different branches namely: tree, metal and polymer. Three interviews were conducted in each branch.The result from the interviews showed that the globalisation had put the companies under hard competition which had made the need for rationalisation and effectivness more apparent. Having said this, the demands on the organisation and the individuals within it will constantly increase.
