Solenergi på Kvarnholmen

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island

This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.

Med kulturen som redskap : En fallstudie om kulturell representation och dess möjligheter att stärka Sverigebilden utomlands

AbstractIn the heart of Paris, you will find Sweden?s only cultural center abroad. Since the early 70?s a wealth of cultural activities has been offered, and every year the center receives more than 100,000 visitors. The center is a branch of the Swedish Institute (Si), a public authority which promotes mutual relationships between Sweden and other countries through culture, education, science and business.

Att leva med hjärtsjukdom. En kvalitativ studie av patienters upplevelser.

Hjärt-kärlsjukdom är idag en av de största folksjukdomarna i Sverige med högst mortalitet till följd. Flera studier visar att uppföljning av patienter, informationsbehov och stöd till patienter efter utskrivning från sjukhusen till primärvården är otillfredsställande. Det finns endast ett fåtal studier som visar på patienternas egna upplevelser av att leva med hjärtinfarkt. För att kunna förbättra vården till dessa patienter är det viktigt att ta del av patienternas egna upplevelser av att leva med en hjärtsjukdom. Syftet med studien är att beskriva patienters upplevelser av att leva med hjärtsjukdom ur ett patient- och livsvärldsperspektiv. Metoden i studien är kvalitativ intervju.

The Capital Structure Puzzle of SME's - Evidence from the Swedish Security Industry

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..

När hjärtat sviktar: Den äldre patientens upplevelse av att leva med kronisk hjärtsvikt

Kronisk hjärtsvikt är en vanligt förekommande sjukdom som för med sig en successiv kroppslig funktionsnedsättning. Ibland är förståelsen i vården liten för den äldre patientens förändrade livssituation då den ofta ses som en del av ett naturligt åldrande. Syftet är att beskriva den äldre patientens upplevelse av att leva med kronisk hjärtsvikt. Studien har genomförts som en litteraturstudie där materialet består av kvalitativa artiklar. Litteratursökningen gjordes i databaserna Academic Search Elite, Cinahl, Medline och Pubmed där sökorden har kombinerats på olika sätt för att få fram relevanta artiklar.

Mekaniserad plantering med Eco-Planter i södra Sverige :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting. Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester. The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive. The biological output, e.g. planting result and survival rate, seems to be quite good.

Stranden och det främmande : En undersökning av ?den Andres? roll och tematisering i Alex Garlands The Beach

In this essay I point out that the presence of  ?Otherness? plays a key role in the novel The Beach by Alex Garland, and that the text relates to a colonial literary tradition. I?ve mainly used the distinction of Otherness and cultural representation presented by the postcolonial theorist Edward W. Said to guide me.

Sexualitet efter en hjärtinfarkt- Behovet av information

Sexuality contains more than just reproduction and is an important part of quality of life. Chronic disease can lead to sexual dysfunction for both males and females. The nurse plays an important role in informing and teaching. Throughout dialogue and observations the nurse can detect possible problems, document and then take measures. The study was performed as information retrieval of literature where the cause was to highlight sexuality for patients that have experienced a myocardial infarction.

Befolkningstillväxtens mosaik i Umeå kommun

The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..

Omloppstid för returenheter

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?

In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

Samtal om hjärtat : Det vårdande samtalet och dess innebörd för patienter drabbade av hjärtinfarkt.

Att ena dagen vara frisk och mitt i livet och nästa dag drabbas av akut och allvarlig sjukdom leder för patienten till en känsla av kaos. Under vårdtiden ska sjuksköterskan hjälpa patienten genom detta kaos och förbereda patienten för att lämna sjukhuset och fortsätta med sitt liv. Detta görs genom vårdande samtal som syftar till att informera om sjukdomen, riskfaktorer och livsstilsförändringar. Samtalen har också en stödjande funktion.Syftet med examensarbetet är att utifrån hjärtinfarktpatienters upplevelser beskriva innebörden av det vårdande samtalet med sjuksköterskan. Det teoretiska perspektivet är det vårdande samtalet.

Ett designprojekt med fokus på för tidigt födda barns emotionella behov i kuvös

Babies born prematurely are deprived of normal sensorimotor stimulation when placed in an artificial environment, the incubator. The aim of this project was to design a series of products that could promote the baby?s emotional and neurological development, and to facilitate parental bonding. The products designed in this project has a theoretical basis on the research available today on cognitive and emotional development in children born prematurely. They were developed in close cooperation with a group of parents and nurses in a neonatal intensive care unit.Presence is a product collection for developmental care, consisting of a mattress, a figure and a necklace. The mattress has vibration sensors that transfer the mother?s heart beat and speakers with recorded heartbeat and her voice.
