The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

Bakgrund: Patienter som ska genomgå elektiva operationer kan uppleva preoperativ oro och ångest. Preoperativ oro kan grundas i bristande information, tanken på att mista kontrollen samt vistelse i okänd miljö. Det vilar ett stort ansvar på sjuksköterskan då hon ska möjliggöra optimal delaktighet i vård och behandling för patienten samt uppmärksamma patienter som inte själva uttrycker ett omvårdnadsbehov. Syfte: Att sammanställa kunskap om vilka omvårdnadsåtgärder som kan minska patienters preoperativa oro vid elektiva operationer. Metod: Litteraturstudie, baserad på två kvalitativa och åtta kvantitativa artiklar.

After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent.

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Background: Children in our present society spend more time sedentary, and food has become more accessible.

Aim: The aim of this study was to describe the nurse?s care of obese children.

Degaardt, M & Rubensson, M. Postoperativt förlopp efter dagkirurgisk ljumskbråcksoperation. Uppföljningssamtal som grund för kvalitetsutveckling. Examensarbete i omvårdnad 15 högskolepoäng. Malmö högskola: Hälsa och samhälle, Utbildningsområde omvårdnad, 2010. Syftet med denna studie var att göra en bedömning av den postoperativa förloppet i hemmet hos dagkirurgiska ljumskbråcksopererade patienter. Data insamlade med hjälp av högstrukturerade telefonintervjuer.

Shivering är ett fenomen som uppstår hos patienterna postoperativt. Det innebär att patienten har okontrollerbara muskelskälvningar som gör att patienten darrar, skälver eller huttrar i mer än 15 sekunder. Shivering påverkar kroppen negativt, men är också obehagligt och ett onödigt lidande för patienten. I takt med den tekniska utvecklingen utarbetas nya operationstekniker och idag utförs flera operationer med laparoskopisk teknik. Pilotstudiens syfte var att undersöka före-komsten av postoperativ shivering hos patienter som opererats med laparoskopisk teknik.

I förundersökningen av balanserade styrkort upptäckte vi tidigt att flera företag frångått modellen efter en kort tids användning, trots litteraturens positiva framställning av den. Vi ställde oss då frågorna när företag väljer att frångå tillämpningen och utvecklingen av balanserade styrkort samt vilka faktorer som påverkar detta beslut. Syftet med uppsatsen blev att genom att jämföra företag förstå vilka faktorer som kan påverka företag att avbryta vidareutvecklingen av styrkortet. Vi valde att fokusera på implementeringen och vidareutvecklingen av balanserade styrkort. Uppsatsen grundar sig på en fallstudie av två företag, Plastic Technology Composites i Kåge och Centek i Luleå, samt intervjuer med två mycket kunniga personer inom ämnesområdet, Christian Ax på Handelshögskolan i Göteborg och Nils-Göran Olve på Linköpings Universitet.

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.

As a result of an increased consumption, waste volumes has grown steadily throughout the 1900s, and this puts great demands on an efficient and ecological sustainable waste management on both local and national level. In order to evaluate collection and disposal of household waste, a large number of Sweden´s municipalities are using waste analyses. The overall aim of this study has been to summarize and assess results from waste analyses executed in Härjedalen´s municipality during the years 2007-2011.The evaluation has given information about the household waste´s composition, quantity and change in time. The report´s objective has been to create a basis which the municipality can use in planning of future information efforts and other measures, and give some proposals on how these can be designed and targeted. Therefore, the report also highlights research on motivations factors that affects environmentally conscious behavior such as recycling, and how different instruments like information can be used to promote this.
