The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.

The aim with this study was to examine professional peoples' view on the reason why females, under the age of 18 years old, self-harm and the professionals view on their treatment. The study is qualitative and based on eight interviews with professional personnel who work with young females with self-harm behavior in the region of Skåne. To be able to analyze our qualitative interviews we used two theories; the attachment theory and trauma theory. The results of this study show that there are many different functions with the self-harm behavior and that the cause of the behavior can be different among the females. Most of the young females seem to self-harm to reduce anxiety but some also do it to punish themselves, to feel alive or to belong to a group of friends.

The aim of this study was to examine why young females develop self-harm behaviour. We also wanted to look at the differences between young females born in foreign countries and young females born in Sweden and investigate if there were any differences regarding the reasons for developing self-harm behaviour and the actual extent of the self-harm behaviour within the group. We used a qualitative method and performed interviews with nine professionals that work with young females with self-harm behaviour. To be able to analyse our qualitative interviews we used concepts such as modernity, anomie, safety and cultural differences in the bringing up of children. The results of this study shows that self-harm behaviour is a symptom of excessive anxiety, which can be caused by a number of reasons, such as childhood trauma or great demands in modern society.

The first two weeks in a pup's life is called the neonatal period. This period is dominated by growth and development of organs and senses. The puppy is born blind and deaf and the physiological disability makes it unable to move properly. The neonatal period is characterized by a lot of sleeping. The pup receives the important milk and warmth from the bitch.

The IT industry is constantly evolving and it's more or less a requirement today for web developers to be familiar with and to be able to develop for all platforms. A technique that has taken hold and is now widely used is responsive design. Developing responsive design means adapting the layout to the viewing environment; the screen size. Another useful method when developing for different devices is the mobile first theory, which means developing for the mobile screen first. This is done to scale down the site and to clear unnecessary information in order to provide a better user experience.

How can a vacuum cleaner motivate you to use it? From a sustainability perspective,the author asked the question of how such a solution would looklike? These where issues that the project tackled and devised solutions for. Theproject wanted to explore the physical modeling and a large part of the finalresult consisted of a full scale model. The project found that the problem ofvacuuming largely consisted of the problem of storage the product. The projectfound that the motivation for the job, therefore, could be resolved by a betterdesigned vacuum cleaner with a built-in hose, folding handles, which couldbe stored integrated within the vacuum cleaner.

Suicidology deals a lot with taking into consideration significant symptoms, risk factors and establishing causal relationships which inevitably are very important for suicide prevention. But do we understand the suicide attempters better thereby? The aim with the study is to elucidate the meaning of the lived suicidal experience that is expressed by participants on an Internet forum. Ten participants' texts which concerned own suicidality were chosen out from this Internet forum and were analyzed and interpreted on the basis of a phenomenological hermeneutical method inspired by Ricoeur (1976). The result established twelve themes that with the aid of Heidegger (1993) and Derrida (1978, 1991) led to that the following conclusions could be drawn about the meaning of the suicidal lifeworld: suicidal concern and care in itself reduces the sense of identity, practical suicidal doing in itself reduces the world, sense of identity is more affected by the future than the present and the past, the death is escaped from through a calculating determination to have the death at one's disposal, inability to turn away from the death increases oscillating between states of emotions, the surrounding world's requirement to avoiding death becomes to a compulsion to isolate one self; and finally: to both feel anxiety in front of one self's own death and dread when escaping from it..

Mergers between companies has become more and more common in Sweden and in the rest of the world with the motive to increase the competitive strength in the current markets and has an important role within organisational development of companies. When organisations merger there is not only buildings and objects that are put together but also their individual organisational structures, people, values and cultures. This can be a difficult process and can affect many people in how they think conscious as well as unconscious, feel and react.The purpose of this thesis is to gain a deeper understanding of how employees are affected following a merger when changes in the organisational culture come up, and how these changes are expressed.This thesis is delimited to investigate only one company, Skruf Snus AB and only focus on their business and employees in the region of Stockholm. The thesis contains a qualitative investigation with semi structured interviews that has been carried out with eight employees at Skruf Snus AB. The thesis is partly based on a model of Schein which describes the different levels in organisational culture and partly on some theories about reactions to change in relation to the integration between the employees following a merger.The results of the investigation indicate that with a merger the whole organisational culture is affected and therefore also the employees.

The intention is to focus on the implementation of the tablet in preschools and how the intentions around the introduction of the tablet take shape in different preschools. The method is semi structured interviews where the respondents consist of 3 preschool directors and 6 teachers where the preschool directors work. This is a relevant subject to illustrate, as the tablet has become a tool in preschool where it seems to be different opinions about how it should be used. This study aims to understand how the implementation can take form in different preschools, what kind of similarities and differences we can see with the intentions of the tablet and if there is need of clarification on the workings of the tablets in preschools. The results show that the intentions around the introduction of the tablet in preschool look different in the preschools, and the implementation of this new technology starts in a small scale with help of photographing and videotaping.

Demens är en sjukdom som ökar i samhället till följd av att den äldre populationen ökar. Sjukdomen innebär ofta en försämrad livskvalitet för den drabbade samtidigt som det leder till samhällsekonomiska konsekvenser.  Vanligt förekommande beteendeförändringar är exempelvis oro, aggressivitet samt depression. Läkemedel är en vanlig förekommande åtgärd vid beteendeförändringar, men innebär ofta negativa konsekvenser såsom oönskade bieffekter samt onödiga kostnader. Musik är därför ett alternativt sätt till läkemedel för att lindra beteendeförändringar, då musiken skapar en lugn atmosfär och en meningsfull tillvaro. Syftet med litteraturstudien var därför att beskriva musikens påverkan på personer med demenssjukdom.Resultatet visade en lindring av oro, fysisk- och verbal aggressivitet samt depression efter det att personer med demens lyssnade på musik.

Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.

This master's thesis asks two main questions concerning the history of the City and UniversityLibrary of Gothenburg: what was the prevailing view of the library and its role? Whateconomic support did the library receive and from whom?By critically examining extensive source material mainly from the library archives and cityand state records, these conclusions are drawn: the City and University Library was regardedas a purely scientific library by all involved except the state as early as the 1920s. The state didnot express this view until 1946. The support came almost exclusively from the city ofGothenburg, the state not extending support on a larger scale until 1946 and then onlysporadically. The widely-held view of the library as a scientific one was ignored by the statein its repeated refusals to grant the library support both before and after 1946.

The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.
