Utvärdering av Raman- och IR-spektroskopi, differentiell svepkalorimetri och dielektrisk spektroskopi för materialstudier på choklad

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Vad påverkas odlarna av i den svenska morotsodlingen? :

In this degree project I write about how the farmers who grows carrots in Sweden get influenced by different rules, investments and demands. The Swedish agriculture are heading towards a harder time, and then you have to find new things to do. Now its hardly no profit to grow grain so you have find other crops. This paper is not a comparison between the contract cultivation to Findus and the cultivation where the farmer maked his products by a own company on the farm. If you have a small processing company on the farm, you have to increase the standard with different certificate. The farmer binds a lot of capital in machines, both field and in the process.

Fiende utan ansikte - en jämförande studie av terroristgrupper under efterkrigstiden

AbstractThe purpose of this theses is to compare three different political groups, The IRA, The Baader-Meinhof group and the Al Qaida, who have all used terroristic methods to achieve their separate goals.By finding out about their history, goals, structures and methods I have made a comparison to see what joins them, what separates them, what originated the birth of their movements and how they can or could proceed with their violent actions to the point that they had actual impact on international politics.It has all been done through a litteraturebased study.My focuse has been on Al Qaida since it's is the only one of the three who is still active today and who, through its cellstructure, represents a new form of global terrorism that may have great influence on the structural patterns of other political groups and criminal organizations in the future.Key words:Al QaidaBaader-MeinhofIRATerrorismCellstructure.

Den offentliga upphandlingens påverkan på entreprenörer : En studie av små och medelstora byggentreprenörer

Public procurement in Sweden is regulated by the Act on Public Procure­ment (lagen om offentlig upphandling, LOU, in Swedish). The Public procurement in Sweden stands every year approximately for 500 bil­lion Swedish crowns of the taxpayers? money. It is therefore im­portant that the money is spent in the best possible way. The focus in this study is set on the relationship between the small- and medium sized building entrepreneurs and the government.

Market analysis for glulam within the Swedish construction sector

Glulam?s position at the Swedish market for building constructions has been established over the past decades. Factors affecting glulam demand are found both in global and national contexts as well in customer attitudes and knowledge of the material. Arguments for environmentally friendly and sustainable construction processes and energy-efficient designs are nowadays common, which is something that should motivate increased usage of wood as a renewable material. For the glulam industry to increase its sales, improve profitability and thereby gain market share in present competitive climate, reliable market information and updated market intelligence is required.

Tjänstekvalitet för pensionssparande : En studie om vilka faktorer som påverkar den upplevda tjänstekvaliteten för pensionssparande

Our purpose of this paper is to seek an understanding of which service quality factors that affects customers in their decision making progress regarding purchasing financial services such as pension products. We also seek to evaluate the different service quality factors by compare their relative strength against each other. The study aim to investigate if there are any connections between customer behavior variables such as gender, age and income in comparison to these service quality factors related to pension products.The findings aim to help a small financial institute such as our case company Plain Capital to understand how their customers experience service quality regarding pension products.In order to find empirical results we conducted a qualitative research as well a quantitative research. The qualitative research employed both a focus group interview with pension savers and an interview with our case company Plain Capital. We were able to identify the service quality factors for pension?s products with help from the focus group interview.

Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data

A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Loggbok och lärande : Elevers perspektiv och pedagogiska intentioner

The purpose of this paper is to juxtapose the theories of learning that are reflected in student?s perspectives of the learning log with that of the pedagogical intentions of the curriculum in order to examine the discrepancy between the experienced and the intentional learning objectives. The paper is divided into two sections. The first section is a literature survey on theories related to the learning log and the curriculum. The second part is constituted by three semi-structured group interviews concerning student´s views on the learning log.

Mellan kommunism och socialdemokrati : - en studie av vänstersocialismens ideologiska utveckling i Norge, Danmark, Sverige och Finland efter Berlinmurens fall.

The purpose of this essay is to analyze the ideological development of the former communist parties and the contemporary left-wing socialist parties of the Nordic countries. It is aimed at the two decades that have passed since the collaps of the Berlin wall and the parties at hand are; the Norwegian Sosialistisk Venstre, the Danish Socialistisk Folkeparti, the Swedish Vänsterpartiet and the Finnish Vasemmistoliitto. Since the 1960´s these parties have undergone major ideological changes with reference to a widening of their political agenda to an inclusion of democratic ideals as well as the new ideologies of feminism and ecologism. Thus reforming them into modern left-wing socialist parties at different times. The main hypothesis is formulated from the idea that there must be a connection between the startingpoint of reformation and the degree of modernism/traditionalism they show today.

Arbetsmotivation i äldreomsorgen: en explorativ studie av uppfattningar hos medarbetare och chef vid ett äldreboende

An explorative study on the work motivation of employees at a retirement home. The three main factors are internal motivation, external motivation and control. A comparison between how important they estimate the different factors to be and how they experience them today reveals which factor is their key motivator and which areas that need improvement. Results indicat that internal and external motivation are slightly more important than control. And the amount of perceived control reflects the amount of creative and initiative behaviour of the individual.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Förutsättningar för jökellopp vid Fox Glacier, Nya Zeeland

A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. This is well known to happen atthe near by Franz Josef Glacier which has similar settings to Fox Glacier, but sparse previous researchon the subject indicates different results of whether jökulhlaups are present or not by Fox Glacier. Thisthesis therefore aims to study the conditions for jökulhlaups at the glacier. This is done by remotesensing and field observations of the sandur in the Fox Glacier Valley, qualitative interviews andliterature studies with a comparison with Franz Josef Glacier.

Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
