In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Since the Internet was introduced, it has taken over faster than anyone was ever expected it to do. It has taken over how we, humans, today live our life and is expected to accomplish our errands, such as paying our bills, ordering clothes and looking up information about travelling.With that said it is important to remember and have in thought that not everyone has the knowledge and skills to use the Internet, this because of the extreme development that the Internet brings.As mentioned above there is one group of people that has been called the ?forgotten group? when it comes to the expansion of Internet, and those are the seniors. Most of the seniors today have difficulties using the Internet due to either lack of knowledge or due to the size of the text on the websites, as well as the different color combinations. Since the seniors today have special needs on how to easily use a website, they are forgotten since most websites aren?t developed for seniors.However, sometimes appearances are deceiving and that is what this study has shown us.By questionnaire and interview study, the result of this study has showed us that the majority of the informants do use Internet, but they have special needs when it comes to the design on a website, and that includes color combinations, sizes of the text as well as on how to navigate from one page to another..

Vårt sätt att kommunicera med varandra är i hög grad situationsberoende. Ett tillfälle när samtalets form kan ha stor betydelse är i kontakten mellan läkare och patient och då speciellt när läkaren behöver förmedla tråkiga nyheter till patienten. I denna studie undersöktes faktorer som påverkar hur läkaren upplever sin förmåga att genomföra samtal med ?bad news? för patienten. Nio läkare på två sjukhus i Mellansverige intervjuades.

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.

The term ?social competence? is widely used by organizations in job advertisements, despite the problems of making a unified definition of it. The purpose of this study is to investigate which features the organizations require, why organizations require them and how the assessment is implemented for recruitment. To answer the purpose of this study, eight qualitative interviews conducted with recruiters from four different staffing agencies. Further a literature study was performed to define the concept of ?social competence? and its meaning, in order to later connect this to the result.

English is an international and global language that students, regardless of mother tongue, encounter in their everyday lives. In Sweden, students are introduced to English teaching in year 1, 2 or 3, and in some cases, year 4. English teaching can sometimes be problematic when the language of instruction often consists of Swedish, which for second language students becomes a challenge to acquire new skills in a week language.The study aims to examine, with a qualitative study, how pedagogues plan and implements English teaching in first grade with students whose mother tongue are other than Swedish. Further, the aim was to examine how pedagogues say they relate to the fact that second language pupils participating in English lessons and if they think it affects their English teaching.The conclusions is that the pedagogues has probably not been problematized the phenomenon examined and say they do not adapt their teaching. In the interviews reveals information about the teaching method which, in my opinion, indicates that, unconsciously, adapting their teaching when they have second language students.

Preschool is a place that is continually undergoing change at a rapid pace and developing the skills of our educators is essential for their ability to keep up with these changes. Guidance conversations can be used as a vital tool for the educators competence development.The purpose of this essay is to investigate how educators, special educators and preschool principals think and reason about the use of guidance conversations in preschool.A qualitative method has been used in the shape of interviews with educators, special educators and preschool principals working within different districts of a medium sized city in the south of Sweden.These interviews revealed that the use of guidance conversations is often controlled by specific needs and is used when a problem arises amongst the children. There are many expectations on the special educators role in these conversations, one of which is the role of conversation leader with the purpose of guiding the conversation amongst involved parties and give them the tools they need to resolve problems by themselves instead of delivering packaged solutions..
