Jakten på den rituella måltiden : Lipidanalyser med GC-MS på cypriotisk järnålderskeramik från kultplatsen Ayia Irini

The aim of this paper was to study fourteen pottery sherds found at the site of Ayia Irini in northern Cyprus using Gas chromatography- Mass spectrometry. Ayia Irini has by the archaeologists of the Swedish Cyprus Expedition been interpreted as a sanctuary, with activity spanning from the Late Bronze Age throughout the Cypriot Iron Age.The results showed traces of vegetable lipids in almost all samples, and traces of lipids from terrestrial animals in all but two. One sample showed traces of resin. Several samples were contaminated by different components found in plastics, such as plasticizers. No obvious common denominators were found for samples of similar pottery type or similar dating.

Decentraliserat lager - ett steg mot flexibilitet

This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.

Efterfrågeprognoser : ?En jämförelse av prognosmodeller med avseende på FMCG-marknaden?

An organization must manage its resource consumption and material flows in order to satisfy the demand of its products as efficiently as possible. Managing of the aforementioned requires a balance between the organizations resources (such as the capability of distribution and production) and the market demand. According to Gardner (1990), an estimation of future demand is a necessity for maintaining the balance. An instrument that is used frequently to estimate future demand is demand forecasting. The demand forecasting practice has been thoroughly studied and a plethora of academic contributions exist on the topic.

Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence

The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

Projektering av passersystem : En studie i användarstöd vid offertarbete för ARX passersystem

To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..

En studie av olika ekonomiska modeller för mångbruk baserad på vindkraft

Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden?s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will leas there land for wind power to wind energy companies. Such land leasing means that the landowner's business is considered to be a multiple-use.

Ett samarbete om samarbete

The following is an explorative work on various forms of collaboration. The core of our exploration revolves around the idea of co-operation as a tool for examination, a collective working method, the input/output within creative practices as well as a phenomena in its own right? It is however not ?simply? about collaboration, but rather places as much focus on a highly personal search for new working methods, new approaches towards research and on the development of our relationship to graphic design. From beginning to end, the entire project has become a work whereby the term ?we? has been more important than ?me? ? a well-functioning project with a common purpose: a collaboration, between us..

En närmare belysning

Detta arbete behandlar ämnet stämningsbelysning för hemmiljö. Projektets huvudfrågeställning är; hur utformar man en belysning som ger användaren möjlighet att skapa önskad stämning i rummet? För att ta reda på detta samlades kunskap kring ljusets effekter på människa och rum. Vidare samlades en fokusgrupp som för att ge sin input om sina vanor, önskemål och behov angående belysning. Förslag på en produkt arbetades fram via en process bestående idégenerering, skissning, modellering och slutligen prototypbygge.

Application development for touch-screen interfaces

The way we interact with computers will soon change dramatically. The input interfaces are becoming more and more intuitive and one of the latest technologies is a touch screen interface capable of dealing with multiple inputs simultaneously. The tools we use to communicate with the computer - such as the mouse and the keyboard, will slowly disappear and be replaced with tools more comfortable and more natural for the human being to use. The purpose of this project was to create a basic framework for future projects dealing with this interface, as well as creating some example programs. This report describes my work and my experiences with this new interface..

Skogen i barnlitteraturen : Kan den fungera som en källa till naturvetenskaplig kunskap?

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

Lågoffsetkomparator

Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.
