Påsköns stenstatyer, moai : Vilket genus representerar de?

Abstract.The question in this analysis is which gender moai, the big statues on Rapa Nui, represent. My hypothesis is that they have developed from visual symbols to metaphores in mythologies from an polynesian context. That these statues were symbols for human origin and creation of ancestors ideological power, and gods in consideration male gender. In the long isolation, in both time and space, the mytologies in Rapa Nui was changed, and the pictures got a new meaning. These changes depended on clearing of wood and big trees and the following difficult situation in farming.

Kvantifiering av osäkerheter i lyftkraftsmodellen

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

Att synliggöra de osynliga : En analys om fyra kvinnliga irreguljära immigranter och om hur deras relationer till andra människor påverkar deras livssituation och identitet

The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.

Den permanenta krisen : En narrativ studie om orsakerna till det första kriget mellan Ryssland och Tjetjenien

The aim of this study is to increase the understanding of the causes of the first war between Russia and Chechnya. Empirical data consists of four half-structured interviews with former Russian and Chechen war participants that tell about their perspective of the causes of the war between Russia and Chechnya. The study used narrative method and the theoretical framework consists of International Relations theories such as Realism, Geopolitics, Liberalism and Marxism. Geopolitics sees the geostrategic interest, territory as a cause of war. According to realism warfare occurs because of the state?s endeavor after power and influence in term of territory.

"Som politiker ska man vara noga med att inte lägga sig i"- Om politisk påverkan i socialt arbete

This study is about the perception of politics in social work. The aim of the study was to seehow people working with social work in municipalities describe their perception of how politicsaffect their work. The study was conducted in two municipalities in middle Sweden,which had a transfer of power in the 2006 election. Six people; two social workers, two executivedirectors and two politicians was interviewed about their perceptions about politics, ifthe ideological direction of the municipal matters, and how politics effect social work and theorganization.

Rätten till Norrland : nutida strider, historisk arena

An introduction to the complexity which surrounds the matters of land in the northern parts of Sweden was the purpose of this thesis. The agriculture colonization, the delimitation and the development of forestry and mining business were big events which are shown from the view of property rights. The situation of the Lappish people and how their situation has changed through the history was the main theme of the thesis. Hopefully this thesis will also serve as a support while reading for example investigations published by the government and judgments by courts. Supply to the resources of nature has always been decisive for the survival of humans.

Det regionala partnerskapet - ett verktyg för Skåne att samverka?

Because of a more globalised world the national states have been forced to make structural changes at both national, regional and local level to cope with different challenges. The regional community has become an important area which has resulted in a policy of more self governing, both for the regional and the local level.The aim of the thesis is to study the relation between regional and local level in the partnerships organisation. To fulfil the aim of the thesis, a case study of Region Skåne is used. The analyse is based on expressions such as cooperation, conflict, power and influence.The result of the thesis confirms that the opinion between the regional and the local level is very different. The representatives from Region Skåne experience the cooperation as quite good because it creates an opportunity for discussions and a possibility to learn from the other actors which in turn creates a qualification in the exchange of knowledge.

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

Transient kallstartssimulering i GT-POWER

Etanol är ett intressant bränsle för framtida motorer där låga emissioner och bränsleförbrukning blir allt mer relevant. Etanol är både förnyelsebart och har intressanta förbränningsegenskaper med ett högt oktantal och snabb förbränning. Användning av förnyelsebara bränslen reducerar utsläppen av koldioxid samt medför att vi inte längre behöver förlita oss på de fossila oljedepåerna.En egenskap hos etanol är att bränslet kräver mycket värme för att förångas. Det medför att kallstarter blir ett problem då det är svårt att få bränslet att förångas och antändas då motorn är kall. Kallstartsförsök har gjorts på en direktinsprutad encylindrig motor med skiktad förbränning.

Projektering av ett småhus med fördjupning i uppvärmningssystem

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control.

Potatisens specifika vikt och kokegenskaper med hänsyn till odlingsplats och sort :

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Vilka kvalitetsfaktorer anses viktigast vid inköp av grönsaker och frukt för återförsäljare i Sverige :

Since Sweden joined the European Union all Swedish fruit and vegetables are classified according to EU Quality standards. One important function is the product description and how it can facilitate the trade; for example in better comparing prices and also to guarantee the quality of the product. This quality standards or product descriptions are written as words of an Act and obligatory for all countries that has joined the EU. It?s often a demand from the customers to be certificated according to some of many certificating systems. One example is the common worldwide GLOBAL GAP-certification system created by the organisation EUREP which represents the leading European retail traders.
