Vind i bebyggd miljö
Målet med detta examensarbete har varit att undersöka kunskapsnivån angående vind i bebyggd miljö hos verksamma inom stadsplanering, arkitekter och inom berörda utbildningar samt tillgängligheten på hjälpmedel och information.
Vinden påverkas starkt av landskapets utseende. Skog, hav, stad och kuperad terräng har alla olika vindförutsättningar. Inom urban miljö bestäms vindförhållandena av bebyggelseutformningen och byggnadernas omgivning.
Historiskt har vindplanering varit en naturlig del av planerandet, inte minst då det gäller jordbruk. Under årens lopp har människor tagit lärdom av tidigare erfarenheter vilket har lett oss fram till dagens kunskapsläge med en rad olika tumregler och hjälpmedel, varav det senaste består i numeriska datorbaserade analysverktyg så som Computational Fluid Dynamics.
En god och komfortabel utemiljö utgår ifrån hur vi människor upplever den.
Exosomes as a potential mechanism of intercellular spread of prion protein
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Porträttering av förorten Tensta
The purpose of this study was to investigate hove some suburban areas image is shown to the public in the media coverage of suburban areas, and this is why I in this paper want to look more closely at the image of Tensta in the news media and how people in Tensta perceive themselves. News media has a very important role in the creation of human worldview. It influences our own identity and affects what a person believes is the difference in us and them. In the post-colonial theory, identity creation is a central role in philosophy, us and them. Based on the above purpose, I formulated an overall main question that this essay should answer.
Indicating relationship success : finding new agricultural Business-to-Business partners by evaluating the potential for relationship success
When a company seeks to enter a new market, the multiple choices of possible new business relationships exist. Further, establishing new relationships is a time-consuming procedure associated with high uncertainty and high costs. Hence, if the firm does not succeed in pinpointing the most suitable business partners to collaborate with, the firm may both forfeit other possible good relationships, as well as resources invested. Based on this notion the aim of this thesis is to explore how a manufacturing company can base the selection of future dealership Business-to-Business partners by evaluating indicators of a possible business relationship?s potential to become successful.
The choice of focusing on the Business-to-Business relationship between a manufacturer and a dealership company originates from being influenced by the issues facing the Swedish agricultural machinery manufacturer Väderstad-Verken AB, who is putting attention to explore the US market.
Psykiskt välbefinnande på arbetsplatsen : En kvantitativ undersökning om arbetsmotivation, arbetsmiljö ochgruppdynamik
Psykiskt välbefinnande på arbetsplats kan kännetecknas av att det finns ett bra samspelmellan arbetsgivare och anställda och en arbetsgivare som förebygger hälsa ochsäkerhet genom att vidtar nödvändiga åtgärder.

Intendenturpersonalens syn på säkerhetsarbetet ombord på ett passagerarfartyg i färjetrafik
Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.

Sjuksköterskors upplevelser omkring omvårdnaden av lätt sederade intensivvårdspatienter
Både över- och undersedering kan öka riskerna för både morbiditet och mortalitet. Genom att ge rätt sederingsnivå till patienterna kan intensivvårdssjuksköterskor medverka till ett snabbare tillfrisknande och mindre vårdrelaterade komplikationer. Sedering är en viktig del i vården av respiratorpatienter och kräver stor kunskap hos intensivvårdssjuksköterskor. Syftet med studien var att undersöka hur intensivvårdssjuksköterskor upplevde omvårdnaden kring lätt sederade intensivvårdspatienter under respiratorbehandling. Uppsatsen är en kvalitativ studie och datainsamling genomfördes med hjälp av intervjuer med sex intensivvårdssjuksköterskor på en intensivvårdsavdelning i Västra Sverige.
Barns rättigheter - en självklarhet?
Numerous studies have showed that Swedish municipalities are responsible for several of the activities that concern children and their rights, e.g. school and health care. Furthermore, the Convention of the Rights of the Child is an international agreement that Sweden has signed and ratified which also implies the obligations that Swedish municipalities have. The purpose of this study is to investigate and compare, from a social justice perspective, how children?s rights are being emphasized and how children?s opinions are being taken into consideration at the municipality level in Sweden.
Ungas avhopp från kommunfullmäktige : En studie om unga fullmäktigeledamöters beslut att lämna sina uppdrag
Young councillors are currently under-represented in Sweden's municipalities. Young councillors are also stepping down in greater numbers than older members. This paper explores the reasons why young councillors choose to resign from their mission, so to identify possible remedies to the problematic trend of underrepresentation of younger people in local authorities in Sweden.This qualitative essay intends, through interviewing politically-active young people who has left their assignment, to study the reasons for resignations from elected posts. To see what could be the reason I have looked at previous studies and theories about opting out but also tried to remain open to identifying new and emerging trends previously undetected in existing surveys.The results showed that the political assignment proved to be too time-consuming, with young people choosing to spend their time on career and leisure. Those who resign from political life often express criticism towards the Municipal Council; they consider it tedious and many complain of having little influence.
Notes Towards a Mental Breakdown : det teknologiska traumat i J.G. Ballards The Atrocity Exhibition
This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system.
Vad innebär EU-Battle Groups insatstid för dess transporter?
Sverige har med sina åtaganden inom EU Battle Groups tagit ansvar för en militär verksamhet som kräver storamått av rörlighet med snabb insatstid. Troliga konflikthärdar kommer inom en överskådlig tid att uppstå långtifrån Skandinaven vilket kräver planering och snabba transporter med stor kapacitet samt lång räckvidd. Enallvarlig kapacitetsbrist i en svensk Battle Group utgörs av bristen på nationella resurser för strategiskatransporter. Avsaknaden av egna militära strategiska transportresurser gör att behovet av civila aktörer och nyagemensamma samverkansformer inom kommunikationstjänsten aktualiseras.Uppsatsens syfte är att analysera hur EU Battle Groups insatstid påverkar transporterna och desstransportförberedelser.Metodmässigt bygger uppsatsen på ett antal frågeställningar vars svar söks genom litteraturstudier ochkvalitativa intervjuer. Den teoriansats som ligger till grund för denna uppsats är systemteorin vilken i sin turhar kompletterats med System Dynamics och dess systemformalisering av materielflöden.Resultat visar på att EU BG med nuvarande resurser inte kan hålla uppsatta tidskrav men med bättreförberedelser kan transporterna påskyndas.
Fader Vår : om fäder med intellektuella funktionsnedsättningar
Most studies on parenthood and learning difficulties focus on mother and child, and very little is know about fathers with learning difficulties. Moreover, people with learning difficulties are rarely asked to tell their own narratives. The aim of the current study is to identify the role of the father in families where one or both of the parents have learning difficulties. Laws and regulations concerning the rights of people with learning difficulties in Sweden are accounted for and the he social support system for all parents in Sweden are described .The empirical study is a qualitative phenomenological interview study, inspired by narrative traditions, and describes how fathers with learning difficulties experience these support systems. The main data are two life stories of fathers with learning difficulties and one observation in a family.The findings suggest that although Sweden has a highly regarded disability policy and social support system, and even though fathers with learning difficulties are assured equal rights as members of the society and as parents by the Act of Human Rights, they are not treated equal but still faces structural inequalities.

Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.
