Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

This literature study summarizes the signals dogs use in intraspecific communication. The purpose is to clarify the way dogs communicate so that situations where their intentions are misjudged can be avoided. The signals are divided into olfactory, visual, auditory and tactile and every section starts with a short anatomic and physiologic description of the sense organ that is used to register the current signal type. The interspecific communication between dog and human regarding its development and function is brought up. To end with suggestions are given of how veterinary technicians in clinics can make use of knowledge about the way dogs communicate.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Pyometra, chronic purulent metritis in metoestrus, is a common disease in intact bitches. About 25% of all bitches in Sweden have contracted the disease before ten years of age. Clinical signs of the disease are varied, and the course may be either slow or acute. The diagnosis is most commonly made by radiographical or ultrasonographical examination of the abdomen in combination with blood biochemical and hematological analyses. The safest and most efficient treatment of pyometra is surgical ovariohysterectomy.There is room for improvement of both diagnostic tools and possible prognostic indicators for pyometra.Mast cells are large leucocytes, with granule that contain inflammatory mediators.

This study investigates the use of the social network Facebook among 67 Swedish libraries; 27 academic libraries and 40 public libraries. Data is collected through an analysis of the libraries? Facebook pages and through an email survey. To analyze the data, a series of statistical analyses were performed.The results indicate that the public libraries more actively posted Facebook updates than the academic libraries and that the libraries that had a policy for use of Facebook/social media more actively posted updates than those libraries that did not have such policy. The libraries use Facebook mainly to post links and photos and to announce events, provide book recommendations, and to emphasize special occasions.

Objective ? To study the requirement of nursing care of the equine patient during eye treatment with a lavage system together with a constant rate infusion pump. Procedures ? Three veterinary nurses at ATG: s Hästsjukhus in Skara were asked nine questions at individual interviews. Inclusion criteria for participation in the interview were that the nurse should have treated equines with and without the infusion pump to the lavage system, but also traditionally with eye drops. Results ? The equine had a higher well-being since it experienced less stress during eye treatment with the infusion pump compared to treatment given by hand through the lavage system. The treatment would be more effective with constant rate infusion and save costs for the owner.

The purpose of this study is to determine which approach preschool teachers from a Reggio Emilia inspired preschool and a traditional preschool have on children, knowledge, learning and their own role in children?s learning. The two pedagogical approaches have different basic visions; Reggio Emilia follows the thoughts of Lori Malaguzzi and the traditional preschool follows the Swedish curriculum Lpfö 98. The main research questions asked were:What view on children, learning and knowledge does the preschool teacher from a Reggio Emilia inspired preschool have in comparison with a traditional preschool?Which role does the teacher believe that they should take regarding children?s learning?What differences and similarities can be identified in the teachers' perceptions?To carry out this study, I used a qualitative research method.

The purpose of this thesis was to examine why so many CRM-projects didn`t reach the expected goals that companies management envisaged. The purpose was divided into two research questions. ? How should companies? management design the strategic projection of the CRM implementation? ? How will employees? attitude to changes influence the result of the CRM implementation? The case company was a Swedish technical consulting company: interviews were conducted with two represents from two different departments. The findings of the study were that management often strongly believes that software will sort out most of the upcoming problems and forget the factor that education of employees is at least equal important.

The aim with this thesis was to study how primary school teachers perceive their mission in working with inclusive education. The aim was also to study their thoughts and experience of the Special education support. To conduct the inquiry twelve primary school teachers from two different communities in Sweden were asked to give their views of inclusive education. The central issues was how the primary school teachers interprets the concept of inclusion, the opportunities and obstacles they perceived and how the Special education support was formed in the work with inclusion in their schools. The result shows that the majority part of the primary teachers interprets the concept as a spatial or social inclusion.

The objective for this study was to acquire a greater insight if children with concentration difficulties are assisted by outdoor education in the traditional teaching. With the use of a qualitative methodology four teachers were interviewed. The outcome gave evidence for that the teachers thought that outdoor education has a positive outcome for children with concentrations difficulties. The findings were divided into three key categories: the teacher?s reflections about outdoor education, outdoor education for children with difficulties in concentration and if there was any difference in how the children behaved indoors after having educations outdoors..

The purpose of this work is to examine how ecotourism exists in Sweden. In order to answer this, the essay has been based on a qualitative method, which means that the authors have mainly used depth interviews for information gathering. Some of the empirical work is also done using the qualitative method, by gathering statistics, figures and scientific articles. The essay is divided into various chapters to give the essay a clear structure and for the convenience of the reader. The part that have been of most use and support for authors is the depth interviews with the interviewees.

The aim of this Master's thesis is to investigate why and how projects with children participating in selecting media at children s sections are made and how the projects effect the collections and the usage of these collections. We have studied literature dealing with how the selection at children s sections traditionally are made, how children participate in society and the question of quality. We have also made a survey to find out whether it is common to do projects like this in Sweden. In addition to this we have studied the discussion of patrons participating in library activities, having found mostly Danish material. Our study deals with five Danish projects, the reports of which we have read, and five Swedish projects, whose responsible librarians and assistants we have interviewed.

ALMI Business Partner operating in the years 2008-2010 a project called Vivan which is about innovations made by staff in the health care profession. The project Vivian is to bring new products to the market by establishing new companies. We have looked at why health care professionals to a lesser extent than other professionals choose to start businesses. Another question raised is why it is mostly men who have chosen to start their own business in the female-dominated health profession. Traditionally, men have as an advantage over women in the corporate market in Sweden.

Background: Mastitis in dairy cattle is a common ailment worldwide. A cause of mastitis can be bacteria such as Escherichia coli. Mastitis is not a deadly ailment and sometimes the dairy cows show no symptoms but if certain virulence genes are present in the bacteria that cause the mastitis, the bacteria can be transmitted to humans and cause severe diseases. The potential presence of enterohemorrhagic Escherichia coli (EHEC) in particular would be a major concern for human health.Aim: The aim for this study was to analyze the presence of virulence genes known to be present in E.coli strains isolated from dairy cows with mastitis in Sweden.Method: A Qiagen BIO ROBOT EZ1 was used to purify DNA from 90 bacterial cultures. A panel of virulence genes were amplified and biotinylated from the purified DNA by PCR and an E.coli based DNA microarray was used to detect presumed virulence genes in E.coli.Result: There were no samples that had all the genes traditionally used to classify E.coli as EHEC or potential EHEC.
