The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

The development of solar photovoltaic (PV) is increasing,with declining module prices and with a strongenvironmental profile. Policies are developed around theworld to achieve the targets set for renewable energy.In Helsingborg, the local power company Öresundskraft isworking with solar PV to achieve the goals of the city.With their vision: - Energy for a Better World and Powerfor the Region, their work with developing the local solarPV market is continuing and the next step is to create asolar PV policy. Today their offer is 1 SEK/kWh for theexcess electricity delivered to the grid.It turns out that compensating the customer is a vitalpolicy and it has to be dynamic to follow the decisions ofpolitics. The same survey shows indeed, thatenvironmental and technical part is of interest. Solar PVwill be supported locally to act on environmentalsustainability and locally produced electricity and withthis Öresundskrafts vision will be achieved..

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.

First during early 1960s fathers got access to the labor room in Sweden. Theirparticipation are a relative new trend and it`s not thoroughly described in theliterature. Midwives? responsibility is to give a good and medical safe care, and tocreate a positive childbirth experience for the woman and her partner. No previousstudies have paid attention to midwives' experiences of fathers' presence duringchildbirth.

This essay is a qualitative content analysis of Flickornas julbok andPojkarnas julbok from 1915/1916 to 1920 and from 1966 to 1970. Mainfocus is the representations of gender that is produced in the books, and howthe ideal of the girl and the ideal of the boy is described.The result shows that the girl is undergoing a change of personality. The idealimage of the girl develops from caring, helpful, compassionate, and diligent,to become independent and brave. The Ideal for the boy in the books, bothfrom the 1910s and 1960s, is described as adventurous, courageous, curious,independent, sensible, strong and loyal. In the 1960s books the girl and theboy are described with similar characteristics, but the girl is also expected tobe cute while boy is expected to be technical and knowledgeable.

AbstractI believe that everyone have the right to understand and be understood. It doesn´t matter if you are an immigrant, suffer from dyslexia or just don´t like to read.In this study I test the difference between a normal written and an easy-to-read routine. I want to know if there is a way to improve a routine in such a way that even people without pre-understanding can comprehend the content.Routines are an important part in many organisations. Staffroutines in nursinghomes don´t exist just to ensure that caretakers are being taken care of in the right way according to the rules and wishes of the organisation. They also exist to make the work with people who suffer from dementia easier for the staff.Routines are in other words very important.

Today, there are more than 12 000-14 000 farms worldwide using an automatic milking system (AMS). Studies have shown that transition to AMS affects the udder health of cows adversely, recognized primarily as elevated somatic cell counts. There are several reasons for this, for example the greater variation in milking frequency seen in AMS. On one hand, short milking intervals may lead to bad teat condition of the cows due to the stress the milking procedure exposes the teats to. Too long milking intervals, on the other hand, seem to predispose for milk leakage, which is, in turn, a risk factor for the development of mastitis.

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

A study by Gulistan Kavak has been done about the therapy school, Liljanschool. The school handles children between the ages seven and twelve who suffer from psychosocial problems. These psychosocial problems may be the children?s? experiences of psychological trauma, attachment-difficulties and anxiety. Therapists, teachers, educators and medical professionals work at Liljanschool. The purpose of this thesis is to see how parents see their children?s? development at the school from there very first day until there last. Three questions have been formulated: How do parents of the children understand the development of the therapy that Liljanschool contributes with? How do the parents think that the school situation has been for their children? Do the school staff´s views and the parent´s views differ regarding cooperation between staff, parents and children?I have done a qualitative study.  In-depth interviews were conducted with the staff of the school and the children?s parents. The results show that the majority of respondents were positive about the school. The analysis shows that through the extension-theory, the children and parents have developed together.

Aim: The aim of this study was to investigate how VAS (Visual Analogue Scale) is used in the prehospital environment, and describe how patients 40 years and older with acute chest pain describe their pain with help of VAS. Further, to investigate how the literature describes other instruments to evaluate pain. Method: This was a descriptive study and used both literature and empiric material as foundation. The selection consist of the paramedics medical record from one emergency department, 100 men and 100 women with chest pain witch had been transported with ambulance to one hospital in middle of Sweden. A literature review was done in order to see what previous research recommends for pain rating scales.Results: The study showed that 71 (35 %) of 200 individuals pain were rated with VAS according to the guidelines for the ambulance department.

Background: Obesity is one of the fastest growing medical conditions both for children and adults. Children with overweight/obesity risk to be exposed to social discrimination and stigmatization from peers. Stigmatization is when the society labels an individual that deviates from what is considered normal behaviour. Purpose: The aim of this literature review was to describe potential stigmatization of children with overweight/obesity. Method: The study was carried out as a general literature review study.
