Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.

En skånsk kvartsboplats, var det en unik händelse?Hösten 1995 gjordes ett sensationellt fynd i nordvästra Skåne. Den första stenåldersboplatsen som kvartsen dominerade, både till antalet och till vikt, hittades vid Hjälmsjöns strand.Uppsatsen kommer att behandla denna plats. Jag kommer att göra en beskrivning av fördelarna och nackdelarna med kvarts respektive flinta. En uppställning på stereotypa bosättningar i Skåne och Småland kommer jag också att göra, detta för att kunna se vilka influenser som är starkast på den här platsen..

??Masada shall never fall again!? A study about Masada as an Israeli national myth during the 20th century? by Sara Tibblin. This essay is about the Israeli national myth of Masada, a cliff in the Negev desert that was the setting of a collective suicide in 73 AD, at the end of the Jewish uprising against the Romans. This story has later been rediscovered and has during the 20th century become a national myth in Israel. This essay will examine how the national myth of Masada has been used in different contexts in Israel during the 20th century and which part it has played when it comes to the national identity of Israel. My findings have afterwards been explained with help of Eriksens theory regarding national myths from the book Historia, myth och identitet (History, myth and identity) (1996).   .

Den här uppsatsen behandlar hur synen på genus och kön inom arkeologisk tolkning kan vidgas med hjälp av Judith Butlers teorier. Uppsatsen är ett försök att finna vägen till tolkningar som går utanför en normativ syn på kön och sexualitet. Med hjälp av Judith Butler har jag utvärderat tidigare gjorda tolkningar av bronsålderns hällristningar och två danska ekkistegravar (Egtvedsgraven och Skrydstrupsgraven), samt själv sökt finna alternativa tolkningar av dessa..

Den här uppsatsen har för avsikt att göra en kvalitativ undersökning av hur arkeologer och arkeologi presenteras i filmer och på tv för att sedan jämföra detta med hur yrkesverksamma arkeologer själva ser på sig och sitt ämne. För detta ändamål har jag tittat igenom ett antal filmer, dokumentärer, tv-serier samt tittat på Internet och gjort intervjuer. Jag kom fram till attdet finns tre huvudtyper av arkeologer på tv/film: actionarkeologer, normalarkeologer och akademikerarkeologer. Av dessa stämmer normalarkeologerna med hur arkeologerna själva beskriver sig. Ämnet arkeologi visas antingen som ren artefaktkunskap, primärt i filmer, eller som en nästan exakt vetenskap, primärt i dokumentärer..

This paper explores the theoretical and practical uses and limitations of battle-field archaeology. The author aims to paint a big picture of the subject of exca-vating, understanding and theorising about historical battlefields done every day by archaeologists. Its approach places much weight on a quantity of examples rather than exploring specific excavations in every detail, in an effort to give the reader an understanding about how battlefield archaeology works. It stresses the need for battlefield archaeology as a way of obtaining and securing impor-tant archaeological and historical information before it is lost to science. The author tries to evaluate the subject in a critical and pragmatic fashion in order to establish a clear understanding about the facts of battlefield archaeology..

Abstract   In this thesis, my aim was to investigate how preschool teachers view their involvement in children's free play. In order to answer this, I chose to do semi-structured interviews with four preschool teachers in three different preschools. My interviews has revealed similarities and support for as how history of research looks at the involvement of educationists. Both research and my results stresses the importance of being active in children's free play and to be a supportive teacher, particulary in conflict situations. For those children who have difficulty entering into the free game its the educationists task to co-play and help the children find the game.

Arbetet bygger pa? teorier fra?n social studies och ma?nniska- datorinteraktion.En fo?rstudie fo?r att underso?ka ma?lgruppen och deras behov av anva?ndargra?nssnittets funktion och grafiska element la?g till grund fo?r att skapa applikationen. En fa?ltobservation utfo?rdes sedan pa?

Due to the Danish kings? engagements on the British Isles, the early town of Lund, was influenced by English and Anglo Saxon traditions, architecture and technology. The main aim of this essay is to find out in what ways, and most importantly how this can be seen in the archaeological material, and how it changes over time. Within a framework of historical sources, archaeological finds like excavated stave and stone churches, cemeteries, pottery, and everyday personal objects, both English immigrants and English influence is found. The problem of the English origin of the palisade wall technique is discussed, as is early Lund as a Viking age town.

This thesis analyses the literature debate in the overlooked Swedish magazine Samtid och Framtid 1944?1949. The magazine was first published at the end of World War II on the initiative of publisher Johan Hansson. After an interesting start, the terms of the debate in the magazine were changed after a power struggle on the editorial level. Thus, the magazine never became the influential arena for literary discussions that it first had potential of becoming.

Aim With this study we want to highlight and analyze the media spin of the PR campaign Miss Skinny by clarifying; a diffusion pattern which covers posts published by bloggers and journalists; a framing pattern from the first audited post to the last; how journalists are influenced by user generated content, and what consequences this may have for the news coverage.Method We have conducted a studied of news posts and blog posts about the Swedish PR campaign Miss Skinny through content analysis, diffusion analysis and mapped direct links between blog posts and news posts.Main result We found that a surprisingly large amount of news postings contained direct links to previous blog posts and that the former media serial no longer can be applied on today's modern media where journalists and other players come together on the converged media arena. .

The text deals with the process of reorganizing and cataloging the archival material emerging from State secondary grammar school in Falun, which appears to have been poorly managed for a number of years. The work was done with consideration to former ways of organizing the material, and a great deal of research was needed in order to establish the outer provenance of the archive.The theoretical discussion goes deeper into the questions of provenance and appraisal in regard to the work,and some choices, especially the decision to reorganize the archive, are motivated with reference to Swedishrules and regulations concerning state authorities' archival management and their duties towards Swedish citizens..
