This thesis is a survey and also an investigation of the different factors that affects the cracking that occurs in the inserts at AB Sandvik Coromants production in Gimo. The work that has been done has focused on two main factors, namely, powder characteristics and pressing parameters.AB Sandvik Coromant produces tools and tooling systems for metal cutting. They have some problems in their production of inserts. The problem is that cracks sometimes occur in the body of the insert, after it´s pressed. In order to investigate this, a preliminary study was made in which production principles were studied.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.

A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

The background to this study is that the field within language education known as collocations is being lost to students. The overall aim of this study was to examine what view foreign language teachers had on the field and how they taught it to their students. This study therefore conducted a survey to compare sentences consisting of wrongly used collocations with other common mistakes that students make. It also conducted interviews on how collocations was seen and taught in school by language teachers. 34 informants answered the survey and four teachers were interviewed to further investigate how collocations were presented to the students.

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

 Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.

The LSH-study started in 2003 at the department of Health and Society at the University of Linköping. The purpose of the study was to examine the relationship between life condition, stress and health. A total of 1007 people from ten different health centres in Östergötlands län participated. At the follow up, a couple of years later, 795 of the 1007 participated. 127 of the 212 in the attrition turned down the follow up, twelve people were not invited (for example in case of death) and the rest did not respond at all.

The investigation has taken starting point in the Swedish school history by a look back at the last three curricula and its rating system in order to see the differences and similarities between them. Furthermore, the focus was on the implementation of lgr11 and how it has worked out both on the national and local levels, with the help of, among other things Imsens "five faces of the curriculum" and Lipsky theories of grassroots bureaucrats. The aim of the study was to investigate teachers' perceptions of differences in teaching and assessment in grades 7-9, during the changeover from Lpo94 both on lgr11.The questions developed for this purpose was: How do teachers say that their teaching changed in conjunction with curriculum change? Has there been a refocusing about the concept of knowledge in the curriculum shift, and if so, how?How the assessment and grading did change with the curriculum change?Data collection has been made using a quantitative survey with qualitative elements. The survey consisted of 10 questions that everyone faces the transition to lgr11.

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors  to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.

In this essay I have chosen to explore how computers are used in preschools. The study was done as a survey. How does preschool seize the children´s culture? In today´s society ICT and computers are a big part of children´s everyday life and reflects on their upbringing.Since I am using computers as a pedagogical tool in teaching the children at my preschool, I find this topic interesting to explore.Are the teacher´s using computers for an educational purpose with the children at preschools or are they using it in other ways?Do the teachers think they have the required knowledge to computers usage in teaching the children in a pedagogical way?What is the teacher´s attitude towards computers in preschool?The essay starts with a introductorial background section where I talk about my own experiences of using computers with the children in my preschool, and then referring to the society then and now, school law, curriculum, teachers' computer skills, media situation amongst children and young people, computer use in preschools/schools and health effects. I have composed a survey based on the answers of 50 teachers in 30 different preschools and in nine different municipalities.The result of the survey is reported and concludes with a part of discussion, where the results are put up against the introductorial background section.

Shopping for groceries often means that, as consumers, we travel to the grocery store ourselves, by ear, bike or on foot. At the store we pick out the groceries that we want, go the register and pay for them. During the last couple of years consumers in Sweden have been given the opportunity to let someone else select and transport the groceries to their home instead, so called home shopping. As this report is being written, the possibility to buy groceries this way is somewhat limited, but many forecasters believe that in the near future it will increase immensely. Because of the large volumes of groceries that are being transported, there is great transport work being done in the supply chain.

Syftet med vårt examensarbete är att undersöka hur passivhus eller så kallade nollenergihus skiljer sig i funktion samt uppbyggnad från konventionella hus.I vår undersökning tar vi upp hur utformning, orientering, material samt ett väl fungerande klimatskal påverkar energiförbrukningen.Vi har tittat närmare på faktorer som sparar energi samt hur ett typiskt passivhus är uppbyggt. För att se hur teorin fungerar i praktiken har vi tittat närmare på befintliga passivhus, nämligen de på Oxtorget i Värnamo.Vi har kommit fram till att passivhus fungerar och vi anser det som väldigt viktigt att man fortsätter driva fram arbetet och informera om dess betydelse för miljön.Passivhus blir mer och mer uppmärksammat. De är något dyrare att bygga, men man tjänar in det i längden. Lönsamheten är dock inte det viktigaste utan känslan av att man gör något bra för miljön..
