En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :

Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable. Seven weaving horses were included in the study.

Empowerment och paternalism på jobbet : En studie kring självbestämmande och delaktighet för brukare i daglig verksamhet enligt LSS

During the latter part of the 20th century the situation for people with intellectual disabilities in Sweden changed and developed. Clients have the right to participation and self-determination in society and in applied measures under the law of individual rights legislation; LSS. The purpose of this study is to describe and understand how team-leaders and managers in day-centres in a municipality works with participation and self-determination for clients, and what the professionals consider affects the client's possibility to self-determination and participation. The research questions intended to be answered are:? How does the team-leaders and managers work to enable self-determination and participation of the users in the public day-centres?? What does the team-leaders and managers describe and understand as enabling and limiting factors for the client?s possibility to self-determination and participation?The study is qualitative and interviews have been held with eight interviewees, which I contacted through snowball sampling.

Föräldrars upplevelser av mångbesök på barnakutmottagningen

Introduction: Frequent attenders is a term used in health care services that define a person attending a health care setting more than four times during a 12 month period. Recently published research concerning frequent attenders in pediatric emergency departments describes their reasons for attending a health care service or characteristics of these individuals but lacks a qualitative approach exploring their experiences. There is a need of these experiences to be shared so that health care personnel caring for this group may gain a greater understanding of their needs and expectations.Aim: The aim of this study is to describe how parents of children defined as frequent attenders experience the care received at a pediatric emergency department.Method: Qualitative approach with semi-structured interviews. A pilot study of four interviews was conducted to test the method. Sampling consisted of parents of children defined as frequent attenders and that were not diagnosed with a chronic illness.

Trikåkonstruktion med 3D-effekt för väggpaneler i lastbilar, ersättning av polyuretanskum

En vanligt förekommande laminering är polyuretanskum, som används för att ge egenskaper som mjukhet, komfort och flexibilitet till textiler. Ett användningsområde som tillverkaren och leverantören Borgstena Group Sweden AB använder polyuretan till är lastbilars väggpaneler. De vill dock ersätta den polyuretanskumlaminerade dubbeljerseytrikån som används idag med endast en ren trikåkonstruktion för att slippa problem som dellaminering och minskade töjegenskaper. Dessutom så har den kemiska sammansättningen av polyuretan som används i lamineringen visat sig vara belastande för både miljö och människor. I denna rapport klargörs varför polyuretanskum behöver ersättas och vilka möjligheter som finns i dagsläget för att göra detta.

Retention av tungmetaller i en anlagd våtmark : studier av Vattenparken i Enköpings kommun

The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.

Konstruera och rekonstruera traditionell kunskap - en diskursanalytisk studie av texter om internationellt utvecklingsarbete

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.

Transformatordiagnostik genom dissolverad gasanalys

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

Kronandelsrelaskopering - metodoptimering och mätfelsstudie : metodoptimering och mätfelsstudie

I dagens skogsbruk bedöms gallringsbehovet utifrån gallringsmallar som ger rekommendationer baserade på avvägningar mellan biologisk kunskap, ekonomiska faktorer och risker. Gallringsmallarna är anpassade efter tänkta produktionsskogar och kan således vara bristfälliga i andra fall. Därför behövs en effektiv bedömningsmetod som fungerar i både homogena och heterogena bestånd. Studier har visat att tallens (Pinus sylvestris) grönkronandel har påvisad effekt på diametertillväxten och genom att uppskatta denna kan ett direkt mått ligga till grund för bedömning av gallringsbehov, istället för det indirekta måttet grundyta, som nuvarande gallringsmallar är utformade efter. Tanken är att undvika produktionsförluster genom att gallra innan grönkronan hissats upp alltför mycket.

Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.

Förekomst av leukocyter i råsperma hos semingaltar :

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Analys av konsignationslager : inom tillverkande industri

In this composition, a study of consignment inventory on basis of the factors which are important for implementation and application of consignment inventory are made. Logistics chain from subcontractor to end customer is becoming more complex when the volume of items constantly increases to satisfy the needs of the market. From that perspective, companies had large inventories but today it is a lot of different solutions to streamline inventory management. One way that recently becomes increasingly common is to let the subcontractor fill up the customers stock using different approaches such as VMI (Vendor Managed Inventory). A further step in the evolution can be to make use of consignment inventory where the vendor owns the stock of the customer.

Carbon sequestration in the pastoral area of Chepareria, western Kenya : a comparison between open-grazing, fenced pastures and maize cultivations

Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).

Ett resecentrums betydelse för en stadskärna . : En studie om Kramfors resecentrums funktion och relation till den urbana omgivningen, samt upplevelsen av denna

The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.

HBTQ-personers upplevelser av vårdmötet

Homo- och bisexuella, transpersoner och queerpersoner (HBTQ) har historiskt sett stigmatiserats och negligerats både globalt och i Sverige nationellt. Individer som inte tillräknats heteronormativet har diskriminerats av samhället generellt, men även inom sjukvård och forskning. Ett resultat av heteronormen är att andra sexuella läggningar och könsidentiteter blir betraktade som onormala. I omvårdnadsarbetet möter allmänsjuksköterskan personer som tillhör HBTQ- gruppen i sitt dagliga arbete, och har därmed ett behov av kunskaper i bemötandet av denna patientgrupp. Syftet med denna studie är att undersöka upplevelser som HBTQ-personer haft i samband med kontakt med hälso- och sjukvårdspersonal i Sverige.

The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation

The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
