Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

During the 8th and 9th of January 2005 a devastating storm named Gudrun entered the south of Sweden and a big part of the forest owners got their forests damaged. The study objective was to investigate on which basis and how the affected forest owners made their managment decisions immediately after the storm and if there are any differences between different categories of forest owners. - Members ? non members in a forest owner association (FOA) - Resident owners ? non resident owners - Female and male forest owner The study is based on a questionnaire survey with the purpose to examine the most important counsellor and information channels of the forest owners. A total of 450 forest owners participated in the survey. Results show that all categories of forest owners prefer professional counselling rather than personal counselling.

Stress is something that has increased in recent decades among adolescents. Several reports indicate that young people today are more stressed because of the many demands they wear. They should be good in school, achievement expectations, get an education or job, make choices and think about their future. The purpose of our essay is that we want to explore and gain an understanding of how young people in the third grade in high school looks to stress. To conduct this study, we used a qualitative approach, by doing interviews with 10 high school students attending third grade at Västerviks gymnasium. The result we got out of the interviews was that young people experience stress differently, depending on their different as individuals. We found that there are different causes of stress, such as school, media, friends, demands from various quarters and choosing education.The interviews showed that some kind of stress was possible to handle for the adolescents, for instance by making schedule. Some stress from society was, on the other hand, more difficult to avoid..

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).

The Swedish Armed Forces is a public institution and consequently obliged to follow Swedish and international legislation. Thus, they are subjected to contrarious demands from different actors operating in its high-technological and high-institutional environment: to be a legitimate institution and at the same time operate with a high level of efficiency. This thesis is conducted with the aim of investigating whether The Swedish Armed Forces' steering document for gender equality is used to achieve visible and quantifiable results or if the document constitute a medium for reverberating legitimacy. To answer the research question, we applied a critical discourse analysis on the relevant documents and on the conducted semi-constructed interviews with members from different levels and positions in the organizational hierarchy. Subsequently, we came to the conclusion that the Swedish Armed Forces manage the demands for efficiency and legitimacy, which are forced upon them from the technological and institutional environment, by talking about them.

Den här uppsatsen behandlar hur elevers reflekterande kring en utveckling inom ett ämne från årskurs sex till årskurs nio ser ut. Materialet består av ett inspelat material från vårterminen 2009. Skolan som eleverna har gått på är en friskola som arbetar utifrån portfoliometoden. Inom portfoliometoden är reflektion ett viktigt verktyg som eleverna ska använda sig av. I skolans kursplaner står det att elever ska kunna reflektera kring bland annat sin egen utveckling vilket också är syftet med den uppgift eleverna har fått i det granskade materialet.

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

ABSTRACTBackground: To be stricken with a cardiac infarction is among other things linked to different risk factors.  Many studies show that the participants in cardiac rehabilitation programs learn to deal with the risk factors, increase their quality of life and lessen the risk for re-infarction.Objective: To describe the lifestyle and perceived quality of life of the individuals after having participated in cardiac rehabilitation program and to see if they had maintained their results up to a year after having a cardiac infarction.Method: The 19 individuals who had participated in cardiac rehabilitation in 2010 after having had a cardiac infarction were asked to participate in the study. Everyone agreed to participate. The study was made analyzing the surveys, one a locally made, that the individuals had filled out four and eight months after cardiac infarction, and the other the generic Quality of life questionnaire EQ-5D, that the individuals had filled out two and twelve months after cardiac infarction. Result: The individuals have not changed their lifestyle after having participated in cardiac rehabilitation which can be interpreted that they have followed existing recommendations. The mean weight increased with one kilogram, no depression is shown and they stress less.

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.
