This thesis examines how to improve the exhibition of products within retail for clothes and gift articles. The purpose is to investigate and test how light sources and different directions of light affect how the products are perceived regarding their exhibition. Our question formulations are:To what degree does the level of light in combination with the background of the interior design of a shop affect whether a product is perceived more or less attractive?What can we recommend to make the exhibition of products more attractive? From our observations shops nowadays have relatively high levels of light when they expose products on vertical areas. We have looked on the recommendation from ?Energimyndigheten? in order to see what they think is important when designing retail lightening.

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

SummaryAt the start of my employment at the Swedish National social insurance office I was a bit confused because there were two categories which I defined as belonging to the same category (working handicapped) but it wasn?t so. The persons I where going to meet was defined as having incapacity to work and therefore, they were defined as not standing to the labour markets conversion. They were defined as being to sick for being at the labour market. The aim of this work is to shed light on what grounds a decision concerning a person which will be categorized as incapable of working and looking at the categorized person?s status.

AbstractThe purpose of this study is to find out how educationalists who are currently working in school-environments feel about antibullyingprograms. Do they think that the programs are working and do they feel that the measures that they use work as planned? The reason why I choose to investigate this topic is that it will always be at topic interesting to study. Bullying will unfortunately always exist in some way. The whole survey is made in a small/medium seized municipality in Sweden with about 12 000 inhabitants.

För att Swepart Transmission AB ska fortsätta att hålla en hög standard på produkter som levereras till kunder, ska monteringslinan för Power Take-Off säkras. Budgeten som är avsatt till att kvalitetssäkra monteringslinan är 500 000 kr. Pick-to-Light och Pick-to-Voice är system som kan användas för att kvalitetssäkra monteringen av Power Take-Off. Systemen jämfördes med systemet med monteringskort som används i nuläget. Det mest lämpliga att införa har visat sig vara Pick-to-Light.I samband med införandet av detta system måste utredningar göras för vilka komponenter som behöver sensorer och vilka som kan säkras på andra sätt.

The purpose of this thesis is to shed light on the various factors that influence the balancebetween the working lives and family lives of social workers. The research questions posedwere: Do social workers consider there is a conflict between their working lives and familylives? Which factors make maintaining a balance between working life and family life moredifficult and which make it easier to do so? How do social workers describe equality betweenthe sexes in their own family? Regarding methodology, the selection method is strategic andcombines data sources with quantitative and qualitative methodologies. The material collectedand via online survey, targeted to 120 municipal employees social workers in a district councilin a big city, and through interviews with four social workers in a rural community. The studywas performed using gender theory and the demand-support-control model.

AbstractMy task was to prepare the already designed heating list ?Stayhot? for manufacturing.I started with drawing the whole list in the CAD-program. It became obvious that some of the designed components had to be changed to work in practice.A turnable reflector couldn?t be combined with the isolation. The suggested light emitting diodes wouldn?t give enough light, so I cut them out and the problem with light remains to be solved.

The dating time spans from 400 ad to 1100 ad. This essay is meant to discuss the dating issue of the early picture stones dated to 400-700 ad and discuss the relevance and validity of the today?s dating.

Labour and its conditions is a subject constantly in focus. Therefore this study aims to shed some light on different factors which constitutes the basis for the definition of optimal labour conditions, as well as creating a need for change of labour conditions. In this case these factors are changes in society and cultures. The study describes how different levels of society - government, employer and employee ? are affected by, or wishes to affect the labor conditions in terms of location, working hours and leisure.

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
