Tillståndsbaserat underhåll till sjöss : Vad föranleder den begränsade användningen av tillståndsbaserat underhåll (CBM) till sjöss?

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.

Buller i bostäder : Projektering av bostäder med hänsyn till trafikbuller

Många av Sveriges kommuner vill förtäta sina städer med bostäder och lokaler för att bygga ett mer hållbart samhälle. Ambitionenär att kunna fylla de luckor som finns i stadsbilden och använda stadsmark som tidigare inte är bebyggd för bostadsbyggnation. Examensarbetet behandlar de problem som trafikbullret genererar och som måste hanteras vid projektering av nybyggnation, samt undersöker de krav och regler som styr den tekniska utformningen och planlösningen av bostäder med hänsyn till trafikbuller. När Skanska tidigare har projekterat bostäder i stadskärnan har man upplevt problem med att få bygglov när den föreslagna planlösningen har sovrum mot bullrig sida. Fokus ligger på de krav och råd som styr placering av sovrum och försöker hitta lösningar som gör det möjligt att få bygglov med placering av sovrum mot bullrig sida.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Ni får ju prata, men... : om skolans pedagogiska idéer och uppdrag utifrån begreppet kommunikation

The purpose of this study is to describe the three most significant pedagogical ideas and their impact on the national curriculum from the concept of communication. As the school is a social learning community this study looks at some teachers? perceptions and experiences of teaching with a communicative approach, and the obstacles they claim to meet. The educationist Kieran Egan argue that these three pedagogical ideas are incompatible and that a curriculum that compromises them is doomed to fail. He mean that a new coherent view on education is required and should be based on students? understandings.

Studie utav ett larmsystem ur ett signalteoretiskt perspektiv : Study of a detector by a signal detection theory

In present-day situation many libraries use detectors so that they can be able to prevent attempts too take out books without registering them. The university library in Jonkoping is one of the libraries that have such a detector. But unfortunately it doesn?t always work correct and can also react on other things a part from books. This is a big problem since the library staff don?t have time to check all signals that comes from detector.

Vad de säger när de säger sina namn : En läsning av det subversiva anspråket utgående ifrån produktionen av författarnamnet Lidija Praizovic?

This thesis examines the way that subversivity is produced in relation to the name of the author, as understood by Foucault, and what potential for ressistance that can be glimpsed there. This from the reading of three text that in different ways relate to that theme.Firstly, throught the reading of "Isis mamma a?r genusvetare, skribent och konstna?r, min mamma a?r f.d. sta?derska, kokerska och dagisfro?ken, numera fo?rtidspensiona?r med diagnosen fibromyalgi" by Lidija Praizovic?, a text that actively work with the internal production of different exteriorities.

Enkätstudie om gymnasieungdomars attityder till stark musik

Bakgrund: Tinnitus och ljudkänslighet är symptom som tycks öka bland ungdomar. En förklaring kan vara att ungdomar tillbringar allt mer och längre tid i bullriga miljöer utan att använda hörselskydd. Syfte: Syftet med studien är att jämföra gymnasieungdomars attityder till stark musik i relation till olika självupplevda hörselsymptom samt med avseende på variablerna norm, risktagande och riskmedvetenhet.Metod: Enkätstudie på 281 gymnasieungdomar i åldrarna 15-19 år, om deras attityder till stark musik. Enkäten bygger bl.a. på frågor och påståenden från Youth Attitude to Noise Scale, Health Belief Model och Theory of Planned Behavior.Resultat: Personer med permanent tinnitus hade mer negativa attityder till stark musik än de som inte hade det.

Organisation och marknadsorientering av äldreomsorgen : En jämförelse mellan Sverige och Tyskland

Organisation and market orientation of elderly careThis comparative literature study is intended to describe how elderly care is organised and financed in Germany and Sweden. Furthermore, it analyses the degree of competition and market orientation in both countries' care systems. Important aspects in this context are the kinds of measurements which are used on the two markets and the question if there are quasimarkets.The theoretical backgrounds of the study are Esping-Andersen's "Three Worlds of Welfare Capitalism" and Harold Wilensky's convergence theory. Esping-Andersen's theory describes Sweden as a social democratic and Germany as a conservative welfare regime which means that there are different conditions for the development of welfare. The use of Wilensky's theory shows that both welfare systems are converging since the end of the 20th century.

Nöjda kontorshyresgäster under ombyggnadsprocessen : En beskrivning och analys av hur fastighetsbolag kan påverka de störningar som uppstår vid ombyggnad med kvarsittande hyresgäst

En av de större utmaningarna med ombyggnadsprojekt är de fall när det i byggnaden finns kvarboende eller andra brukare under tiden. En ombyggnad innehåller i regel både bygg- och rivningsarbeten som ofta medför störningar för människor som vistas i eller intill fastigheten. Samtliga störningar är påverkningsbara och kan vid god projektering och produktion minskas.Målet med examensarbetet har varit att ge konkreta förslag på hur ett fastighetsbolag kan arbeta för att öka hyresgästens kvalitetsupplevelse under en ombyggnad som sker i eller intill hyresgästens lokal. Detta har gjorts genom att identifiera vanliga störningar, genom att påvisa hur hyresgästen har påverkats av dessa störningar och genom att undersöka hur tidigare uppkomna störningar har hanterats.I samråd med fastighetsbolaget Vasakronan har tre ombyggnadsprojekt valts. På respektive ombyggnadsprojekt har kontorshyresgäster, intern projektledare och extern projektledare intervjuats.  Även observationer i form av platsbesök och litteraturstudier har genomförts.Studien har resulterat i förbättringsförslag till fastighetsbolaget.

Vindkraft och rennäring

The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined. The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.

Transport av häst på land :

The aim of this review is to evaluate the best way to transport the horse. When it comes to transporting horses there are a number of different types of trailers and trucks that you can choose from today. The most common type of trailer is designed for two horses and the horses are transported facing the direction of travel. Studies has been performed to determine if that is the most advantageous direction for the horse to travel in, in terms of balance and levels of stress. Stress is a widely discussed subject and the definition is not fully developed.
