Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

Lagerdimensionering vid bearbetningsproduktionen hos Volvo Powertrain i Skövde

Volvo Powertrain tillverkar motorer och drivlinor till AB Volvos samtliga dotterbolag förutom Volvo Aero. Vid anläggningen i Skövde tillverkas motorer och delar till motorer och växellådor och vid anläggningen finns alla tre nödvändiga produktionsområden; gjuteri, bearbetning och montering. När rådande lågkonjunktur slog till stod bearbetningen med väldigt höga lagernivåer vilka företaget snabbt tvingades sänka då det blev huvudfokus från koncernledningen att minska det bundna kapitalet. Utan egentlig analys sattes nya gränsnivåer för lagren inom samtliga avdelningar på bearbetning och målet med examensarbetet har varit att ta fram en metod för att dimensionera säkerhetslagret på optimal nivå med bibehållen hög leveranssäkerhet. Därigenom skulle företagets lagernivåer kunna styrkas med hjälp av en teoretisk grund.Som utgångspunkt har en lagernivådimensionering med servicenivåkonceptet SERV2 och där alla artiklar tillåts ha differentierade servicenivåer använts.

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Genuskommunikation i biblioteksvärlden: hon och han i kvinnosfär

The librarian profession is dominated by women. The aim with this essay is to find out howmen and women in this field get on together, and how they experience their psycho·social work situation bearing this in mind. Are there any advantages or disadvantages being a woman or a man in this profession? What do the librarians think about the future? Men and women working at five different public libraries, where the domination of women is greatest, have been interviewed. The essay is based on their opinions and experiences.The female and male librarian get on well with each other and have a good cooperation.There are not many advantages or disadvantages depending on the sex in the profession, but the image, status and salary would probably be better, if there were more men in the profession.

Patienters oro inför anestesi : En litteraturöversikt

Syftet med studien var att beskriva förekomst och typ av patienters eventuella oro inför anestesi. Litteraturöversikten har baserats på vetenskapliga artiklar av både kvantitativ och kvalitativ art. Trettioen artiklar granskades och 21 av dessa valdes ut till resultatet.De flesta studier som behandlade oro inför anestesi var av kvantitativ art. Oro i form av olika slags olustkänslor definierades av flera författare utförligt och på flera sätt. Resultatet påvisade att oro var ett vanligt förekommande fenomen och kunde objektivt mätas med hjälp av självskattningsskalor, där de vanligast förekommande är Visuel Analog Skala (VAS) och State Trait Anxiety Inventory (STAI).

Förändrad interaktion, förändrat värde? : En kvalitativ studie om värdeskapande vid mänsklig och teknisk interaktion

The progress in the field of technology is often described as massive and its development has had a great impact on the social development (Vetenskapsrådet, 2012). As a result of the digital evolution, there has been a change in the way customer and company interact (Normann, 2011). The traditional way for players to interact with each other required an interaction human to human (ibid), a mode of interaction that now can be replaced or supplemented by todays technology and often Internet-based solutions (Salomonson et al., 2013). These technological solutions, the technical interaction, are often referred to as self-service systems. These systems enables the customer to carry out the tasks previously performed by the company (Hilton and Hughes, 2013).

Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)

Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

Formatets betydelse : hur arbetsprocesser och produktionsvillkor formar journalistiken i webb-tv

New technology has created new opportunities for journalists working with web TV. Changes in the work processes have led to new professional roles. According to the theory of media logic such events become news that suits media organizations and working conditions. How does the media logic affect the editorial workflow and how does it affect professional roles? In light of my own experience in various roles in television journalism, I examine how the web TV format shapes the work of journalists.

Välkommen, vill du bli som oss : En studie av införandet av medborgarskapstester i Danmark, Tyskland och Storbritannien

The aim of the study is to evaluate how a law decided 2002 regarding discrimination against students in the higher education system in Sweden, was implemented at the University of Kalmar and Växjö University.The study asks two questions: How did the both universities implement the law? How did the universities manage to implement the law? In order to answer these questions the ?top-down? perspective, often used in field social science within discipline implementation, is used. First the study examines the goals with the legislation, and thereafter the actual implementation at the both examined universities.The conclusion is that the universities has high ambitions with implementation of the law and extensive formalized regulations but that it practically seems to be hard to get legitimacy with the implementation throughout the whole organizations. This makes the implementation work slowly though it?s working well with the people who have direct responsibility for the implementation..

Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..

Effekter av stresshantering utifrån Acceptance and Commitment Therapy (ACT) och övningens betydelse för förändrat förhållningssätt hos universitetsstudenter

The aims of the present study were to implement and evaluate a three-session Acceptance and Commitment Therapy (ACT) stress management intervention in a non-clinical group of university students (N = 25) and to investigate the importance of practice in an ACT-intervention. A design with pre-test and double post-test was chosen. A comparison was made between a nine-hour ACT-intervention containing practice for the participants, a two-hour lecture on ACT and stress management containing no practice for the participants and a control group. Psychological flexibility was assessed with Acceptance and Action Questionnaire-2 and mindfulness was measured with Kentucky Inventory of Mindfulness Skills. Perceived stress level was measured with Perceived Stress Scale.

Användargränssnittets positiva effekter på minnet

Studies in the field of interaction design and the human memory claim there can be positive effects on the memory when information is presented for the user as a graphical pattern rather than a series of numbers. This thesis aims to influence designers to choose graphical patterns as an interface for information display. Low-fi and hi-fi prototypes of graphical patterns were constructed and tested in a variety of configurations by two users. The users showed differences in the ability to memorize a sequence of digits depending on how this sequence was presented. This study suggests that users are more easily able to recall information presented via a graphical user interface than when the same information is only presented digitally..

Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.
