This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Bakgrund: Denna litteraturstudie handlar om avnavling och när det är optimalt att avnavla det fullgångna friska barnet. Avnavling har länge varit ett diskuterat ämne bland obstetriker, barnmorskor och föräldrar. Föreliggande studie ska bidra till att öka barnmorskans och övrig vårdpersonals medvetenhet om när avnavling bör ske och när det är fördelaktigt för barnet att avnavlas. Rekommendationen är att friska fullgångna barn avnavlas sent om inte situationen kräver en tidig avnavling eller att föräldrarna önskar tidig avnavling pga. donation till biobanken.

The aim with this paper is to examine the political background of the schools comission to integrate pupils with special needs in the public school. These following questions are examined: What political documents are the elementary? Which ones are juridically binding for the schools? What are the experiences for  parents of children with special needs in the school? The method used for this paper is mainly litterature-studies. The four documents which are examined are: skollagen, Läroplanen 94, FN:s barnkonvention och Salamancadeklarationen. The theoretical frame for this paper is political documents, curriculums and how schools concretize the special education.

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

The aim of this study was to analyze how discourses about domestic violence emerges in policy and practice, and to investigate how those discourses may change from a structural, political level to a local, practical level. The research questions focused how the problem of domestic violence is formulated at national and local level, scrutinizing the different discourses framing and reproducing the causes and solutions of the problem, and also to deduce how different context affects formulations. The empirical material consists of policy plans and interviews with social workers. The findings indicates that the issue of domestic violence is articulated differently on different levels. In action plans on the national level, the domestic violence is formulated within a structural discourse, being a problem on a (gender-) political level, whereas professional social workers recognizes domestic violence as a personal problem within an individual oriented discourse.

The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

In Sweden the social assistance from a historical perspective, has been a part of the social legislation, since the 18th century. In that time called poor relief. Through the centuries this has established the social assistance we have today. With focus on the child, we have attempted to illustrate how the social workers consider the child perspective when they are dealing with the social assistance. We wanted to get a view of how the social worker reasons about needs the children have and how they can see that the benefit has been provided for.

In today?s health care it?s most common to treat an illness with a kind of pharmaceutical preparation. But lack of resources, given information and bad communication and collaboration between the patient and the nursing staff can lead to a patient unwilling to follow the doctor?s prescription. This does not just affect the individual patient?s health but it can also result in consequences for other people and the whole society.

Syftet med den här studien är att ta del av några föräldrars och pedagogers tankar kring integrering av elever med Downs syndrom i grundskolans verksamhet. Undersökningen bygger på kvalitativa intervjuer med åtta personer, fyra föräldrar och fyra pedagoger. Intervjuerna har genomförts i två olika kommuner. Utifrån genomförda intervjuer framkommer det att alla deltagare är av den uppfattningen att integrering fungerar bra och påverkar eleverna positivt. Både föräldrar och pedagoger är av åsikten att den integrering de har erfarenhet av har fungerat nästintill optimalt.

Bakgrund: Nästan vart fjärde barn i Sverige har idag en allergisjukdom med symtom. Att som barn få diagnosen födoämnesallergi har en påverkan på både barnets och hela familjens livskvalitet. Syfte: Syftet med studien var att belysa hur en familjs livskvalitet kan påverkas då ett barn har födoämnesallergi. Metod: Studien baserades på sju vetenskapliga studier, både kvalitativa och kvantitativa. Resultat: Efter att ha granskat studierna framkom tre genomgående teman; upplevelser av oro och rädsla, upplevelser av bristande stöd och information och begränsningar och strategier i det dagliga livet.

The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.

The objective of the essay has been the studying of the importance of religion for children. To answer and satisfy my objective, I have some questions: How do children talk about their own and others? religions? In what way do children associate themselves to religion? Which meaning does religion have for children?s identities? Which thoughts rise about religiontuition in the school?To answer the problem formulation, I have done a qualitative interview study with five children of different religious and cultural backgrounds in a Swedish communal school. The results showed that children?s thoughts about religion are mostly inherited from the parents.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.
