Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Aortic Body Tumors in Dogs
The purpose of this essay was to review the literature and describe the patophysiology, diagnosis, microscopic and macroscopic appearance of aortic body tumors in dogs. The tumors originate from the chemoreceptor organs situated at the base of the heart. The chemoreceptor organs are neuroendocrine cells responsible for surveillance of changes in e.g. the blood pH. Aortic body tumors are rare and represent 7 % of the total cases of primary cardiac tumors in canines.
Beteende inför lek hos odlad respektive vild lax (Salmo salar L.) i Klarälven
In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.
Fysiologisk jämförelse av sprintintervallträning och högintensiv intervallträning
Sprintintervallträning (SIT) och högintensiv intervallträning (HIIT) är relativt nya träningsmetoder som används av både idrottsaktiva och motionärer för att öka både prestationsförmåga och hälsofrämjande fysiologiska effekter. Syftet av denna studie var därmed att undersöka de fysiologiska förändringar som uppkom efter två veckors SIT och HIIT hos tio unga, friska motionärer. Försökspersonerna delades in i två homogena grupper, en SIT-grupp (n = 5) och en HIIT-grupp (n = 5). De båda grupperna utförde fyra förtester för att fastställa kroppssammansättning, anaerob effekt, benstyrka och maximal syreupptagningsförmåga innan en två veckors träningsintervention startade. Under det första intervallpasset mättes de akuta effekterna av träningen och efter avslutad träningsperiod upprepades förtesterna för att påvisa eventuella fysiologiska förändringar.

Greklandskrisens påverkan på bankernas interna risker : En studie om svenska storbankers kreditrisk
Background: 2009 it has occurred a crisis in some of the member states of the European Union: Spain, Portugal, Italy, Ireland and Greece. Despite, some major banks in the world had begun to recover from the financial crisis that occurred from 2007 until 2009, there were still banks who found it difficult to survive. Greece is one of the countries that suffered from the financial crisis. The high budget deficit and the unsustainable debt are underlying the crisis.Banks as financial intermediaries have important function in a nation?s economy.
En jämförelse mellan versionerna 1.2 och 2.0 av WAP
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Cross-suckling when sows are group housed during lactation : associations with sow productivity and behaviour
Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling.
The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.
Impairment test av goodwill : En ny djungel för en revisor?
Inför år 2005 infördes nya regler för hur goodwill i företag ska hanteras. Detta ställer nya krav på hur företag ska hantera goodwill, men detta innebär också nya problem och gransknings-möjligheter för en revisor. Uppsatsen syftar till att lyfta fram svårigheterna för en revisor när denne ska granska ett av företagets gjorda impairment -test av goodwill och vilka medel som den har till sitt förfogande för att genomför granskningen. Studien grundar sig på intervjuer med revisorer och branschorganisationer. En revisor är styrd av lagar och redovisningsprinci-per när denne ska granska ett företag men revisorn är också beroende av den information som kommer ifrån företaget.
Optimering och design av Gruvberget Svappavaara
Den stora efterfrågan på järnmalm i världen har lett till att LKAB inrättat ?LKAB 37? som är ett projekt med målsättning att öka produktionen med 35 %, vilket innebär 37 Mton färdiga järnmalmsprodukter per år. För att uppnå målet har LKAB startat upp Gruvberget som är en av tre planerade dagbrottsgruvor i Svappavaaraområdet. Produktionen i Gruvberget kom igång under 2010 och drivs av LKAB:s dotterbolag LKAB Berg & Betong. I dagsläget är gruvans livslängd uppskattad till år 2016 och planen är att bryta 2 Mton magnetitmalm per år.
Musik som hjälpmedel för att öka aptiten hos äldre
It has long been discussed how to use music in a new way in the field of food and elderly, and in this study, the authors wanted to test this. Music is the language of emotions. It?s a powerful tool, but its effects are difficult to predict (Theorell, 2009). Malnutrition in the elderly is a serious condition that often gets overlooked (Edfors & Westergren, 2012).
Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.
The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.
