The birth of a child marks a new era for the parents. It is the beginning of something that will never end, because they will always be the child´s parents. This study investigates what happens when an infant is born whit Downs syndrome (Ds), and thus does not resemble the child the parents had expected. The purpose of this literature study was to describe the information and the support that the parents of a newborn child with Ds think that they need. The literature search was made in the database of Medline (via Pub Med), Academic Search Elite and manual search.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..

A favourable economic situation in Sweden has lead to a very good market for agricultural real estates. The estate agents? ads in the daily newspapers, where they actively are seeking assignments, give a hint that the supply is smaller than the demand for agricultural real estates. This situation ends up in a competition between real estate agents to get as many assignments as possible to meet the demand from the market. Describing and explaining the sellers? decision process may give a specific agent an advantage towards other agents.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

The aim of this essay is to examine how students in 6-9 grade with reading and writing difficulties are treated and supported by teachers and staff at Ideskolan, a community school north of Stockholm. I have chosen to answer the following question:- How does Ideskolan cope with and support students with reading and writing difficultiesThis has in turn generated the following questions:- How is special education organized at Ideskolan?- Is a diagnose always needed in order to deploy extra support?The method I have employed is observation while participating, together with informal talks and interviews. I have visited Ideskolan twice, one week at the time. The material that the visits have generated is the foundation of the essay, supported by previous research in the field.The essay clarifies what right to special support students have according to law, regulations, curriculum and teaching plans and what they look like in reality at Ideskolan.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

As companies grow, their need for computing power will increase, which traditionally resulted in companies having to invest in more IT resources. Now, with cloud computing, companies can easily hire computer power over the Internet, on-demand. Cloud computing offers a highly scalable environment where companies can store data and host their services. This paper employs a qualitative study with interviews and literature studies to explore opportunities and challenges associated with cloud computing from a system developer perspective. The aim of the paper is to find out how cloud computing changes the conditions for system development. The paper contributes with four different opportunities and challenges that the system developer must handle to succeed in the world of cloud computing.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

A major part of the Swedish population suffers from myocardial infarction. A wish in the study is to give nurses an increasing knowledge about what patients with myocardial infarction wish to be informed about so that the nurses can meet these patients as good as possible.The aim is to show what nurses need to inform heart patients about to prevent anxiety and fear after hospital care.The method used was literature reviews where seven articles were reviewed according to Polit, et. al., (2001). The databases used were Cinahl and ELIN.Results: There is a dissonance between what the patient and what the nurse is ranking to be the most important item to be informed about after a myocardial infarction. The patients prioritize information about symptoms and lifestylechanges.

Den första process som möter den akutsökande patienten på en akutmottagning är triaget, vars syfte är att bedöma patientens medicinska tillstånd. Att hänvisa en akutsökande patient till annan vårdnivå är ett komplext beslut, som ska fattas med kunskap, erfarenhet och med respekt för den enskilda patienten. Syftet med studien var att beskriva sjuksköterskornas upplevelse i hänvisningssituationen av akutsökande patienter, med Triagehandboken som beslutstöd. Metoden var kvalitativ med semistrukturerade intervjuer. Åtta sjuksköterskor på en akutmottagning i södra Sverige inkluderades i studien.

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.
