The purpose of this thesis is to study five pedagogue?s view of the free play and their view of the importance of the free play for children´s learning and development. I have chosen to use a qualitative research method in the form of interviews with five pedagogue´s from a preschool. The main research questions asked were:What have the pedagogues of view on the free play? How important believe the pedagogue that the free play is for children?s learning and development? What has emerged in the study is that educators have a positive view of the free play. They believed that the free play is important for children´s skills.

Sköldkörteln (tyroidea) är ett endokrint organ som påverkar ämnesomsättningen. Tyreoidea stimulerande hormon (TSH) frisätts från hypofysen och stimulerar syntes och frisättning av tyreoideahormonerna trijodtyronin (T3) och tyroxin (T4). Tyreoidea hormonerna har i sin tur en negativ påverkan på frisättningen av TSH. TSH, T3 fritt och T4 fritt analyseras på serum med immunokemiska metoder. Becton Dickinson (BD) har tagit fram ett snabbkoagulerande provrör för analys av serum.

The purpose of my study is to examine how four teachers reflect on free play and controlled play in preschool. What are their reflects concerning free play, controlled play and children?s development and education. The main focus of this research is the experiences of the teachers and I compare their perspectives against each other regarding free and controlled play.To be able to realize this study, I propose the following questions:What kind of vision does the teacher have concerning free play and controlled play?According to the teacher, how does playing affect the children?Which development areas are affected by participating in the play?This is a qualitative study, based on interviews with four teachers from two different preschools.

Vid nuvarande framställning av kontroller och kalibratorer för läkemedelsanalys med LC-MS/MS-teknik används idag serum där fibrinogenet har fällts ut med kalciumklorid. Eftersom detta tros ge upphov till ökad jonsuppression skulle plasma där fibrinogen istället tagits bort genom frysning/tining kunna användas. Denna studie har utförts för att undersöka om och hur dessa två olika matriser skiljer sig vad gäller bland annat jonsuppression och enhancement, och studien innefattar även obehandlad plasma. Studien har utförts i samband med analys av två olika metoder för läkemedel, som bland annat utgörs av neuroleptika och bensodiazepiner. Postkolonn-infusion utfördes för båda metoderna och ingen nämnvärd jonsuppression eller enhancement kunde påvisas för någon av de tre olika matriserna.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

The purpose of this study is to find out how four preschool teachers view children?s free playing and its impact on their learning. My main questions are:How do the teachers view the children?s free playing?In what ways does the children?s free playing affect their learning, according to the teachers?This essay is based on a qualitative study in which I have interviewed four female preschool teachers of different ages. I highlight various theories of children?s playing and learning in preschool, by theorists such as Vygotsky, Lillemyr, Knutsdotter Olofsson, Lindqvist, among others.

Clinical signs of hypocalcaemia in dairy cows are easily recognized, and a rapid response to treatment generally confirms the diagnosis in the field. However, clinical signs of other disorders in cows, such as toxemia, calving paralysis, or muscoskeletal injury, may mimic those associated with hypocalcaemia. Therefore, making a diagnosis of hypocalcaemia on the basis of clinical signs alone may be difficult. In ambulatory veterinary practices, cow-side tests are useful to make the diagnosis and prognosis easier. Kruuse?s Kalcium Test is a cow-side test based on the principle that calcium ions are necessary for coagulation of blood, and that chelation with EDTA prevent coagulation.

The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.

The analysis of acute phase protein serum amyloid A (SAA) has recently been brought into clinical use in veterinary medicine. Some of the difficulties with incorporating the SAA method in clinical practice have been the expensive and rather large equipment required for the method. Due to these difficulties only larger clinics can afford to use the SAA analysis.The company Equinostic has recently developed a smaller instrument that costs one-tenth of a larger instrument. The instrument is named EVA1 and has so far only been used to analyze SAA in horses.The aim of this study was to investigate if the EVA1 instrument could be used to analyze SAA in cats. This study included 24 serum samples from cat, which were first analyzed twice on the EVA1 instrument and then sent to the Strömsholm Referral Animal Hospital in Sweden where they reanalyzed the samples using a validated reference method.

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Problemställning och syfte: Bromerade flamskyddsmedel (BFR) används i många varor och produkter. Polybromerade difenyletrar (PBDEs) är en av dessa och deras kemiska struktur liknar den i miljögiftet PCB och kan på samma sätt lagras upp i miljön samt skada människor och djur. På arbetsplatser där BFR förekommer riskerar medarbetarna att exponeras. I den här studien har olika BFR undersökts i samband med servicearbete på flygplan. Målet har varit att jämföra förekomsten i damm och luft, samt blod (serum) med resultat från tidi­gare studier.Metod: Damm- och luftprovtagning har genomförts vid olika faser av service­arbetet.

Abstract   In this thesis, my aim was to investigate how preschool teachers view their involvement in children's free play. In order to answer this, I chose to do semi-structured interviews with four preschool teachers in three different preschools. My interviews has revealed similarities and support for as how history of research looks at the involvement of educationists. Both research and my results stresses the importance of being active in children's free play and to be a supportive teacher, particulary in conflict situations. For those children who have difficulty entering into the free game its the educationists task to co-play and help the children find the game.

The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and thus the stress for the animal and also in order to increase the possibility of starting relevant treatment early on. The aim of this pilot study was to determine whether Serum Amyloid A (SAA) could be a measured in blood samples from bottlenose dolphins (Tursiops truncatus), Asian elephants (Elephas maximus) and South American tapirs (Tapirus terrestris). SAA rises to its maximum about 24 hours after the introduction of an inflammatory agent in companion animals. This also correlates with the estimated time it takes for animals at Kolmården Wildlife Park to be examined and having blood samples collected after being observed as sick. The study also evaluated whether the Eurolyser SOLO, using a turbidometric immunoassay (TIA) developed for human diagnostics, could be used for such analysis. This pilot study was a retrospective analysis of SAA in convenience sampled frozen serum, collected from dolphins, elephants and tapirs.

The purpose with our essay was to increase our knowledge about what social workers, with experience from working with drug addicts, perceive as the explanations to a person stopping the abuse and succeed in staying drug free. Our framing of the question was:- How do social workers define the term drug free?- How big a roll do the social worker believes she/he has in the process in which a person stops abusing drugs?- How do the social worker work with a person towards getting that person drug free?- What do the social worker believe to be the reason why a person stops abusing drugs?- What do the social worker perceive as helpful for a person to stay drug free?We did qualitative interviews with six social workers. Our main conclusion was that it is difficult to define the term drug free. The reason for stropping the drug abuse can vary, it can be the family situation, "hitting rock bottom", finding love or tiring.
