Landström : Undersökning av svenska hamnars ekonomiska möjligheter att investera i landströmsteknik
Syftet med studien var att undersöka svenska hamnars möjlighet att investera i landströmsteknik och sedan betala tillbaka investeringen genom försäljning av elektricitet till ankommande fartyg. Studien är en systematisk litteraturöversikt baserad på en systematisk litteratursökning som sedan presenteras i en teoretisk fallstudie. Litteraturöversikten utgår från fem studier som beskriver kostnader gällande utbyggnad av landströmsteknik. Första delen av resultatet består av beräkningar för vad investeringskostnaderna för utbyggnad av landströmsteknik till en enstaka kaj kan uppskattas till. Därefter beräknades kostnader för att generera en viss mängd elektricitet ombord och jämfördes med kostnaden för att köpa den från marknätet. Sedermera beräknades en vinstmarginal om elektriciteten säljs för samma pris som den kostat om den genererats ombord i dieselgenerator.
Scenografi till Batboy - the musical
This is the project of making a stage design for Batboy ? the musical, a cooporation with a network of musical artists. The aim of the project was to create a space on stage that strengthens and expands the experience of the story told, and find design solutions that give an extra dimension to the story. The prerequisites for my work were partly defined from the produc¬tion, as were my limitations. In the cast of ten artists some were to play more than one role, often one of the opposite sex.
Lärlingsutbildning som skolform : Hur ställer sig lärare, elever och handledare till det?
The purpose with my study was primarily to illuminate the students' expectations on gained knowledge during their studies at the upper secondary school Hotel- and Restaurant program, and to what extent these expectations were fulfilled. Secondarily, the purpose was to compare the students' expected and perceived knowledge with the program goals set by the Swedish government and the knowledge requirements expressed in a pilot study made by the Education council of the Hotel and restaurant business (UHR, 2007).I chose a quantative approach and I used an anonymous group enquiry among students at the Hotel- and Restaurant program at two different upper secondary schools to carry out my study.Tendencies in the result suggested that the students at the Hotel- and Restaurant program expected high knowledge level within the competence areas of Guest reception and communication, Cleaning and hygiene, Cooking of cold and hot dishes and Waiting. The expectations were not big within the areas Computers and Internet and Business economics and management.Fulfillment of expected knowledge tended to be high within the areas where the expectations were big. It might therefore be a good investment for schools to work on the student expectations to increase motivation within the low expectation areas.A confrontation of the tendencies in the result with the program goals and the competence requirements expressed in the UHR study, suggested that the upper secondary Hotel- and Restaurant education might focus some more the areas of Guest reception and communication, Beverages and Organization of banquets. Business economics and management should be given much more weight..

En analys av centralkylan i Slakthusområdet i Stockholm
In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

Att äta kakan och ha den kvar : En hållbarhetsprövning av John Haughts evolutionsteologi
From underwater boat to submarine ? The development of the Swedish submarine service 1945-1960 The scope of this essay is the development of the Swedish submarine service during the period 1945-1960. The aim is to answer the following questions:- What kind of new technology did Sweden acquire when salvaging the German type XXI submarine off Gothenburg at the end of World War II?- In what respect did this technology differ from that of the Royal Swedish Navy and did it subsequently contribute to the tactical and operational development?- What tactical and operational development was accomplished between 1945-1960?The timeframe, 1945-1960, was chosen since this is when the analysis of the salvaged type XXI submarine and related effects was conducted. Furthermore, it is also during this time that the Swedish submarine service is beginning to evolve as a result of the new knowledge mentioned above and the experiences made by both the allies and the Germans during World War II.The theoretical framework primarily refers to the theories on naval warfare by Sir Julian Corbett.
Nationella identiteter i det återförenade Tyskland En studie om hur fyrtio års separation av den tyska nationen i BRD och DDR har påverkat den tyska identiteten
Abstract (magisteruppsats, 61-80p)This paper is concerned with the national sentiments in the Federal State of Germany,regarding the east- and west-German cleavages, since the unification of the country in 1990.The point of departure is the nationalistic theory crafted together by the scholar AnthonyDavid Smith, which implies an ethno-symbolistic perspective on the dynamics of nations.The main question in the paper is to which extent you can consider the East- and WestGermans to be a unity, considering the past and the forty-year-division. For this reason theauthor basically uses two different sources: scientific books and the German journal DerSpiegel.Founded on Smith's theory, the study contains a broad explanation for national identities incontemporary states, which ranges from pre-modern times, when the ethnic communities werecreated, to the national world of today.The discontinuity of the German case, represented by the separation 1949-90 of the Germannation into two entirely different societies, makes it possible to draw conclusions about whichfactor that has the pivotal impact on national identities.The result turns out to be that the national historical core-values and symbols of the currentGerman state and nation are more profound than the splitting national sentiments. Thus theGerman nation is likely to recover from its Cold War break-up.Keywords: German unification, A. D. Smith, Nation and nationalism, National identity, DerSpiegel.
Examining Accuracy : Drönare och drönarangrepp: retorik, praktik och historia
The military conflicts of the early 21st century have seen the introduction and rise of a new military technology: the armed drone. With the United States acting as the driving force behind this technological advancement, the U.S Air Force and intelligence agency CIA have madedrones their weapon of choice for pursuing suspected terrorists and insurgents in various remotelocations. American military leaders and policy makers assert that the armed drone?s high levelof accuracy make it the best available weapons platform for this task. However, new researchshows that the use of drones may result in more civilian casualties than previously thought, andmay in fact be more fallible than conventional aircraft in this respect.
Beslutsfattande och Gränssnittsdesign : Gränssnittsdesign och dess påverkan på hur människan fattar beslut
Människans tankesätt och beslutsfattande är en alldeles unik egenskap, som hon har. Unik är den på grund av att alla har olika uppfattningar, erfarenheter och värderingar. Den här studien handlar om hur man kan påverka människans beslutsfattande genom ett gränssnitt, och vad det är som påverkar beslutet. Då det finns många faktorer som har en påverkan på beslutsfattande, specialiserades studien på användaren och dess kognitiva egenskaper, så som uppmärksamhet och perception, samt en fördjupning på beslutsfattande och gränssnittsdesign. Detta för att kunna svara på vilken påverkan ett gränssnitt har på en människa som interagerar med det.Under studiens gång gjordes enkätundersökning, personas, prototyper, användartester, samt observationer, för att kunna analysera och få in tillräcklig data.
Häckar för Smålands inland : en översikt
Häcken är ofta ett självklart och naturligt element i en trädgård. Som trädgårds-ingenjör kan det vara svårt att välja en lämplig häck till ett gestaltningsförslag. Det krävs att vi tar hänsyn till flera parametrar, både för att häcken ska trivas men också för att kunden ska bli nöjd. Det kan därför ta mycket tid att leta upp en häck som uppfyller alla krav och önskemål som finns, tid man oftast inte har.
Syftet med det här arbetet är att studera lämpliga arter för häckar till villaträdgårdar i
det småländska inlandet. Arbetet har gjorts med hjälp av litteraturstudier samt
intervjuer med plantskolor.
Kubakrisen : En tidningsstudie om svenska morgontidningars rapportering kring krisen
AbstractKubakrisen; En tidningsstudie om svenska morgontidningars rapportering kring krisen The Cuban Missile Crisis; A media study of Swedish morning papers reporting about the crisis The purpose of the survey is to illustrate how four Swedish newspapers, Svenska Dagbladet, Göteborgs Handels- och Sjöfartstidning, Dagen and Ny Dag reports about the Cuban missile crisis based on the questions. The survey highlights what distinguishes the morning papers and by how they take the position of the ship blockade against Cuba that United States issued and what position they take on who to blame in the conflict, but also how leaders Khrushchev, Kennedy and Castro portrayed. The study is based on the basis of a newspaper study and theory of priming serves as an instrument for the collection of materials. The survey results show in the first issue of how the papers stand to US ship blockade, which SvD endorses, while GHT and Ny Dag condemns it and Dagen stand in the middle without any real position. Previous studies treated SvD stance during the Cold War, shows that during the Vietnam War in 1965 SvD was very critical of the USA and their involvement. In this study, regarding the Cuban missile crisis, SvD are most clearly pro-US while Ny Dag accuse and highlights strong criticism of the United States. As for Chrusjtjov, Kennedy and Castro, the survey shows that three out of four newspapers writes about a surprised Chrusjtjov, who had gone too far and a Kennedy who are determined and implacable.
Kan olika virussjukdomar blockera varandra? En studie baserad på övervakningsdata
Background: Infectious Diseases Institute points out that the potential of various viraldiseases possibly can block each other. It is said that the virus that causes common cold,Rhinovirus, may have saved many people from the flu. If this assumption proves true, itwould explain why some viral diseases in some countries have been slow to take off and pointto a new way to struggle influenza. Objective: The main purpose of this study, based onreported cases of RSV and influenza type A, type B and H1N1, investigate whether viraldiseases can block each other, i.e. difficult season of flu may delay and / or mitigate thespread of RSV in Sweden.
N?r staten talar om kris och krig : En analys av broschyren ?Om krisen eller kriget kommer? 1943-2024
This study examines how the Swedish state has communicated security, threats,and citizen responsibility to the population through different versions of thebrochures ?If Crisis or War Comes?. Drawing on securitization theory and UlrichBeck?s theory of the risk society, the study analyzes how threat perceptions, protected referent objects, and the role attributed to individuals have changed overtime. The analysis is based on a deductive qualitative content analysis of sixbrochures published in 1943, 1952, 1961, 1989, 2018, and 2024.The findings demonstrate a clear transformation in the construction of threats,shifting from a predominant focus on conventional military conflict during theSecond World War and the Cold War to a more diversified threat landscape in thetwenty-first century, including societal disruptions, propaganda, cyber threats,environmental risks, and pandemics.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
