This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

The purpose of this literature review was to investigate how the rearing systems influence the behaviour of dairy calves. Calves are social animals that form groups within the herd where play and social licking between calves are important social activities. Suckling is a complex behaviour and essential for the calf's survival. In the modern rearing systems the calf is usually separated from its mother soon after birth. Calves are then kept in individual pens, group pens or, more rarely, with a foster cow.

Schizophrenia can cause symptoms such as auditory hallucinations, delusions, emotional blunting, apathy and lack of motivation. These result in a diminished ability to participate in daily activities and bring the client group into the domain of occupational therapists. The purpose of this literature review is to compile the latest findings in occupational therapy interventions for individuals with schizophrenia. Furthermore guidance regarding the utility of the interventions will be given based on the author?s assessment of the evidence in the 22 articles included.

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

The specified purpose was, based on gender, age and type of employment, study the employees motivation to participate in health projects and their reason to maintain exercise habits after the termination of the health projects. Exercise frequency was studied in relation to the other background variables. A revised version of the questionnaire Motivation for Maintenance of Exercise Habits (Josefsson, 2005) was distributed at Albany International, Halmstad. The most frequent cause to exercise was ?enhance my condition?.

The music industry has been subject to great changes during the last ten years. The most significant factor contributing to this change is the increasing usage of broadband and thereby the increasing frequency of downloading music illegally. Music piracy and file sharing have caused record sales to plummet. Consumers have now moved on to consuming music in a digital format, not only through downloading but also from streaming music online, an activity partly made possible by social media channels such as YouTube. As the consumption patterns have changed companies within the music industry have been forced to find other sources of income than record sales and they have also needed to find alternate ways to market their artists.

The relationship between the pet and it's owner is a very important and interesting issue. Unfortunately there is not so much research on this and in addition to that Swedish veterinarian education does not put much emphasis on pet's role in society or their pattern of behaviour nor treatment. This thesis is based on an opinion poll that 20 dog owners and 20 cat owners contributed. The main purpose of the thesis was to compare the relationships that the pet (dog or cat) and its owner can have. The issues such as the pet owner's attitude to his/her pet, how the pet owner percieves and interprets the signals from the animal, and what they think about the natural behaviours and needs that their pets (might) have. The results show that dog- and cat owners are people who generally love animals, that they used to have even other animal species in the past, but when it comes to choice between a new dog or a new cat they choose the one that they previously have had and that they are used to. Most of a dog owners choose the dog to be their pet because of the company while the majority of a cat owners choose cat because cats are independent and they are used to cats.

There are several objects of age whose provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Based on last years events that have taken place, events on the school Lundbergs and the police values of work, has the meaning of having a set of values been questioned. This study aimed to investigate and answer the fundamental values based on the common value basis for the government employees within an organization and how it perceived by employees. The new institutional theory was the framework for this qualitative study conducted with semi-structured interviews. Respondents were employees within the organization. Ethnographic qualitative methodology was the basis for our methodology and we used a thematic model of theme interpretation, communication and knowledge in our analysis.

ABSTRACTMy degree project has resulted in the improvement of the guidance in the dental center?s entrance. The patients will now find it easier to understand and find the environment?s various functions, which is the reception, registration, payment, and waiting rooms. Norrbottens läns landsting has a concept ?hälsofrämjande väntrum? that provides guidelines for how they want their patients to experience their waiting rooms.

The standard model concerning the relationship between perception and motility is linear and one-way. It depicts the flow between the two as moving from sensation to perception to representation to computation, and finally, to motility and action. According to this model, animal being is basically a bundle of reflexes. But what can correctly be considered a bundle of reflexes from a natural science point of view, doesn't necessarily have to be true. This conception does not take into consideration the more complex interactions between motility and perception that constitutes, or generates, animal and human beings.

This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.
