This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.

Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.

Abstract: A public service sector in constant reformation is a common phenomenon in Sweden. This also includes the municipal care organisations. A central role in those reformations has the public middle chief who often is the one to implemented reforms to the organiza-tion's staff.This study is examining the role of the public middle manager in care organisations dur-ing the implementation of common ideologies value foundation in a present organisa-tion's reform. The study tries to elucidate in which way the public middle managers in municipal care organisations experience their roles, which expectations the management of the organisation has on their roles and how a present organisation changes inflict on the contents of the role. If the middle manager in a municipal care organisation feels like normative for the personal group is another aspect.There are four concepts used as theoretic framework in the study, organization, imple-mentation and public middle managers in a general aspect and the middle manager in a municipal care organisation in a specific aspect.

Epilepsy is a common neurological condition in dogs, being a common reason for death in the statistics from the insurance company Agria in Sweden. Among the different types of epilepsy, idiopathic epilepsy (IE) is the most common and is characterized by the fact that a veterinary examination does not reveal a cause for the seizures. This study has been conducted through studies of medical records and interviews with dog owners. From a total number of 103 dogs that were neurologically examined for seizures, 42 dogs met the inclusion criteria, being classified as having idiopathic epilepsy. When the study was performed, 28 dogs had died, while 14 were still alive.

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

The purpose of my study was to examine how teachers in physical education experience different frame factors impact on their outdoor education and their choice of didactic approach. My study is based on Lundgren´s frame factor theory and Peitersen´s didactic learning model. I have used a qualitative research method to answer my questions. I have been using semi-structured interviews to interview six PE teachers who all teach at high school level.Based on my results we see that the teachers experience teaching hours and class sizes as the frame factors that mainly affect the outdoor education. Teachers often choose to split up the outdoor activities into sequences in order to achieve better learning.

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

The purpose of this essay is to explore the significance for former drug addicts who, during their treatment against drug abuse, have had a therapist with a drug addiction in his or her past. A qualitative case study has been used as method in which four former drug users have been interviewed. We have compiled the results based on five key themes in order to get a comprehensive picture of the relevance of common experiences regarding drug abuse, based on former addicts? experiences. This has been done in connection with a review of different theoretical perspectives that we have found relevant to the investigation. Our findings have then been compared with previous research in the field.

Syftet med denna litteraturöversikt är att göra en utvärdering över de mekanismer som är viktiga vid tumörmetastasers nybildning av kärl s.k. angiogenes och med vilka metoder man kan hindra dem. Tumörceller som prolifererar ohämmat utan att stimulera angiogenes begränsas av brist på näring och ineffektiv bortförsel av slaggprodukter och kan därför sällan växa och bli större än cirka 1mm. Detta medför att även om det kliniskt finns många små metastaser i en patient så innebär det sällan något problem för patienten. Om tumörcellerna däremot muterar så att de kan stimulera angiogenes så tillåts tumörerna växa sig större och förstör då kringliggande vävnad vilket tillslut resulterar i patientens död. Mycket forskning görs i nuläget inom ämnesområdet och man har som mål att med hjälp av angiogeneshämmare göra cancer till en kronisk men hanterbar sjukdom istället för den sjukdom med dödlig utgång som den ofta är idag. Den första angiogeneshämmaren som godkändes för medicinskt bruk i USA var Avastin (Bevacizumab) som är en antikropp som binder till och oskadliggör vascular endothelial growth factor (VEGF), vilket är en av de faktorer som stimulerar angiogenes. Detta får som följd att de tumörer (60 % av alla humana) som uttrycker denna faktor hämmas i sin tillväxt.

When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.

The aim of this study was to examine former criminals? experiences of help and support of importance to leave a criminal life style. The study consists of six interviews with former criminals and earlier studies on the subject. These studies show that relapse in crime are most common among those who are socially excluded from society. They also show that important factors to end a life in criminality are for example a supportive social network.

ABSTRACT: Introduction: There are intentions from the Swedish government to provide guidelines and tools for a healthy social planning. The field is in a Swedish context relatively unstudied regarding psychosocial health and the neighbourhood. Aim: The study aimed to examine how social planning can affect the health of individuals. The focus areas were contextual and compositional factors related to individuals' psychosocial health and the contextual risk- and health factors that exist in the neighbourhood. Method: A literature-based study was conducted and 15 scholarly articles form the basis for analyse.

Stroke is one of the most common diseases in Sweden and the third most common cause of death (National guidelines concerning stroke, 2000). Dysphagia is a common problem for stroke patients with almost 50 percent of patients suffering from severe swallowing dysfunction (Axelsson, Asplund, Norberg & Eriksson, 1989). The purpose of this study was to investigate how stroke patients with dysphagia experience their swallowing disorders. The method used was a qualitative literature study. An analysis of content was carried out using ideas and inspiration from Graneheim and Lundman (2003).

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.
