Gradering av vindkraftslägen i Lerums kommun med hänsyn till infrastruktur och läge
The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.
Betydelsen av hästens hud och päls för reglering av kroppstemperatur i kyla ? vad händer vid klippning och täckning?
The horse is a homeothermic animal and to keep a constant body temperature in winter season is important. Acclimatisation is to provide means for a good thermal insulation consisting of skin, hair, and an outer air layer. The skin covers the horses body and it is composed of three main layers where the top layer of the epidermis consists of dead keratinized cells that are constantly being sheed. The dermis is composed of collagen connective tissue that give the skin its strength. The bottom layer with subcutaneous fat provides a thermal insulation and can be used as an energy reserve in cold weather.
Konsekvenser av förändrade partistorlekar - en undersökning på Volvo Car Body Components
Volvo Cars Body Components i Olofström tillverkar karosskomponenter till Volvos personbilar. De senaste åren har produktionsvolymen ökat betydligt, samtidigt som hårda krav på rationaliseringar ställs inom koncernen. En parameter som skulle kunna minska kostnaderna och effektivisera produktionsflödet, är partistorlekarna i pressning. Idag är partistorlekarna anpassade efter några dagars kundbehov och man är oense om partistorlekarna tar hänsyn till om artikeln har ett högt styckvärde eller kräver små lagerutrymmen. I vår uppsats har vi använt oss av metodtriangulering, vilket innebär att vi har kombinerat ett kvalitativt och ett kvantitativt synsätt för att komma till vår slutsats.
Montering av isolering på vattentank
One of today problem at IVT industries would be assembly of insulation on water cisterns. The element of assembly insulation on the cistern gets too elevated; hence one has to climb onto the stand the cistern is assembly on. This will increase the risk of work related injuries when there is a risk of falling down. It?s also rather strenuous on shoulders due to work with your arms high above your head.
Samband mellan BMI och kariesprevalens hos barn och ungdomar - en litteraturstudie
Övervikt och fetma hos barn och ungdomar har blivit allt mer förekommande och prevalensen ökar dramatiskt över hela världen. Sedan raffinerade kolhydrater introducerades har även kariessjukdomen fått större utbredning. Då det finns gemensamma bakomliggande faktorer som påverkar både vikt och kariesprevalens vill vi i vår litteraturstudie undersöka om det finns något samband mellan body mass index (BMI) och kariesprevalens för barn och ungdomar. Efter sökningar i den medicinska databasen PubMed på artiklar från de senaste 5 åren fann vi oeniga resultat med jämn fördelning. Resultatet av litteraturstudien är att två av de undersökta studierna tyder på att det inte finns något samband mellan BMI och kariesprevalens, lika många anser att det finns en svag eller möjlig association, medan två studier ansåg att det fanns ett signifikant samband.
Upplevelsen och konsekvenser av att leva med Body Dysmorphic Disorder - en fallstudie av en 22-årig man
Studiens syfte var att öka förståelsen för och kunskapen om upplevelsen av att
leva med Body Dysmorphic Disorder (BDD). Fokus i upplevelsen låg på känslor och
konsekvenser i livet men också för individen själv. Med konsekvenser för
individen avsåg exempelvis konsekvenser för självuppfattningen, rädslor och
framtidstron hos deltagaren. Den metod som användes i studien var
semistrukturerad intervju vilken genomfördes via chattservicen MSN och via
e-mail. Den initiala intervjun efterföljdes av ett antal uppföljningsintervjuer
då nya intressanta aspekter fanns i den första intervjun.
Gravritualer vid gånggrifterna på Falbygden : En undersökning av den materiella kulturen inne i och utanför graven
This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.
Kronisk mitralisinsufficiens hos hund : samband mellan graden av klaffinsufficiens och det arteriella blodtrycket
Myxomatous mitral valve disease is a common disease in older dogs of small- to medium-size breeds. The mitral valve, and less commonly the tricuspid valve may be affected which causes them to leak blood from the ventricle to the atrium of the heart during systole. With increasing severity of mitral valve leakage the forward stroke volume ejected into the aorta decreases, which may lead to an increase in blood pressure in the pulmonary vein resulting in pulmonary edema. A decrease in cardiac output may lead to a decrease in blood pressure, but the body may respond in order to normalize the blood pressure. Franzén showed in 2007 that the systolic blood pressure was increased in dogs with severe mitral insufficiency.
Litteraturstudie : Prevalens, tänkbara orsaker och konsekvenser till ätstörningar
The present work has been implemented as a literature study aimed to investigate the prevalence, possibly causes and consequences of an eating disorder. In today's modern society individuals are living with a constant reminder from the media about how a person should look and act to blend into the social norms and expectations of the modern society. This literature review has been analysed on the basis of concepts such as identity, gender identity and gender. In addition previous research has been analysed in terms of themes, history, possible causes/risk factors, media, body image and control, depression, shame and guilt as well as culture. The above themes were analysed on the basis of behaviouristic theory and role theory.
Tillfrisknande och användning av hästar med fång :
Laminitis has crippled horses through times and many cures have been used to
treat it. Since the mechanism of the disease is yet not fully understood, treatments
are only ways to alleviate the pain and at best, slow down the pathological process
enough to make time for improvement. This paper is a retrospective study of 71
horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies
three visits at zero, five and fifteen weeks. At each the horse is evaluated and
treated by a veterinarian.
Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
Tvåstegsavvänjning av köttraskalvar med hjälp av nosbricka :
When beef calves are weaned abruptly at 5 to 6 months of age this triggers a strong stress reaction, since the animals have not yet untied the bonds to their mothers or stopped suckling. This is displayed as extensive vocalization and restlessness. Attempts to diminish the negative effects of weaning on sucking calves have been showing varying results.
The study presented here emanates from the observation that when calves are weaned without human interference they are only prevented from suckling, but are still allowed to have social contacts with their mothers. The hypothesis was that calves weaned in two steps would be calmer, gain more weight, and be healthier than animals that were abruptly weaned. To investigate this, 15 calves where weaned in two stages (Group 2), by fitting the calves with nose tags that prevented them from suckling during 5 days prior to the separation of the cows and calves.
Vindkraft i norra Sverige. Inventering av lämpliga platser för vindkraftsetablering i de sex nordligaste länen.
The interest for wind power has increased in Sweden. Northern Sweden is especially interesting due to that a new wind resource map shows that there are areas in northern Sweden that have more potential for wind power than what have been known before. Therefore E.ON Vind is interested in finding out if, and where, there are suitable places for establishment of wind power in northern Sweden. The purpose of this master thesis is therefore to perform an inventory of northern Sweden for suitable places for wind power. The master thesis is performed at E.ON Vinds office at Vasagatan in Stockholm.

Tidsberoende kvantkemiska beräkningar av optisk absorption hos polymerer och molekyler med litet bandgap
The vertical electronic excitation energies for the narrow-bandgap polymers LBPF, EP37 and EP62 have been calculated using Density Functional Theory (DFT). Also the vertical excitation energies for the acceptor unit of LBPF have been calculated using the Hartree-Fock (HF), DFT and Coupled Cluster (CC) methods. The calculations cover the visible and infrared wave length region and two strong transitions are obtained, one corresponding to the pi to pi* transition and one corresponding to the pi to Acceptor transition. The excitation energies obtained from DFT are below the corresponding experimental results and attempts have therefore been made to perform bench-marking calculations using a hierarchy of CC methods..
