Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

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.

"Det är såhär en riktig man ska vara" : En retorisk analys av hur manlighet framställs i podcasts

This study examines how masculinity is portrayed in podcasts. Our original materialconsisted of four episodes of C/o Hannah & Amanda and four episodes of Filip &Fredrik's podcast. We analyzed the programs both individually and in comparison toeach other. Using a rhetorical analysis, we found that the perception of men in thepodcasts conforms to societal norms. The theoretical basis underlying ouranalysis can be expected to strengthen our findings and made us also realize that theimage of masculinity is constantly evolving..

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

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.

Kan probiotika förebygga atopiskt eksem hos högriskbarn?

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

Psykoakustisk påverkan av basfrekvenser : Blir vi påverkade av låga basfrekvenser som vi inte kan eller knappt kan höra med örat?

This survey tries to find out if and how we can be influenced of extreme low and strong frequencies in the area 0-40 Hz. A group of 52 teachers/musicstudents and non musicstudents was trying to assess what they thought, experiences and tried to describe why they thought as they did, when they listen on three different versions of same musical piece. Without low frequent bass, original and strengthened bass, randomly mixed. Several different musical pieces was used in same survey. The work also makes a commitment to theories about the people's hearing and the will of ?selfmotion?.

Säkerhetsbrytare för Gräsklippare

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower.

It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

En studie inom upphandling av GPD

The Swedish State Road Administration has since 1992 procured operations and maintenance of state roads on the open market. The procurement has been termed ?Grundpaket Drift?, GPD, and comprises mostly operational measures for road networks.The clients of GPD, SRA regions, have gradually changed the original documentation in order to adapt it to local conditions. This process has gradually led to that some parts of the documentation are creating problems for contractors interested in procuring jobs.This thesis tries to analyze GPD and clarify the differences that may be essential to the procurement process and to facilitate future joint working projects and processing descriptions..

Johan Axel Björkman och P.A. Björkman : Två prostarkiv

This essay has its background in the work I?ve been conducting organizing and cataloging two personal archives concerning the life and work of two vicars, Johan Axel Björkman and P.A. Björkman. The time span of the papers stretches from 1823 to 1982.The main problems I?ve been confronted with during this work have to do with respecting provenance and original order.

Det lustfyllda lärandet - : ?Fem myror är fler än fyra elefanter? som ett led i läs- och skrivinlärningsprocessen

The purpose of our study was to examine how three teachers and four students relate to the program "Fem myror" in teaching. We have been through qualitative interviews with two teachers and one special teacher received a detailed picture of how their literacy programs made in relation to the "Fem myror." Qualitative interviews have also been made with four students, a boy and three girls, in order to examine their attitude to the program. From educators? interview answers, we think we can say that the theory and practice conform to what we read in the literature may be associated with what we observed during our time in the business. The study has shown that all teachers believe the program will be a good educational tool to take to read and write.

Vart tog brevskriverskan vägen? : En analys av Iselin C. Hermanns Prioritaire

The objective with this essay was to compare the modern epistolary novel Priority by danish author Iselin C. Hermann with the epistolary genre during its heyday in late seventeenth to early nineteenth century. I especially looked at gender: the similarities and differences between the female character in Priority and the female characters during the epistolary novels days of glory. I concluded that Priority has the same structure, characteristics as the heyday epistolary novel and that the female character does not have any typical similarities with its stereotypical female characters. In addition I also came to the conclusion that she is reminiscent to their original model Héloïse and follows the epistolary novels heyday convention when she dies at the end of the novel..

Indoor Positioning Using WLAN

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..

"Klyschor som funkar" Göra rätt saker eller göra saker rätt : En studie om service recovery i hotellbranschen

Every business is subject to service failures. The process of correcting these failures and turning disappointed customers back into happy ones is called service recovery. This is particularly important in the hotel business, where there are many moments of truth where customers may become dissatisfied. To further complicate things, service recovery is a process where you may have to correct errors of others - people beyond your control. The research field is relatively new and there are no turn-key solutions as to how to systematically work with service recovery.

En manuell utvärdering av extraktionssammanfattade texter.

Att göra sammanfattningar med hjälp av datorer istället för att manuellt skriva dem är något sommånga försöker komma på en bra lösning för. Hur man ska utvärdera om de sammanfattningar somproduceras är bra är dock ingen självklarhet och flera olika lösningar har föreslagits. I denna studieanvänds det svenska högskoleprovet som grund för att undersöka hur stor skillnad det är mellanoriginaltexterna och deras motsvarande extraktionsbaserade sammanfattningar. I studien visas attdet går nästan dubbelt så snabbt att läsa en trettioprocentig extraktionsbaserad sammanfattningjämfört med dess original. Skillnaden i antal rätt svar mellan sammanfattningarna ochoriginaltexterna blev cirka 10 procent sämre för sammanfattningarna än originaltexterna.Sammanfattningarna skattades också som sämre i de subjektiva skattningar försöksdeltagarna fick göra för varje text..

Marknadsundersökning av Claas Lexion tröskor : kapacitet och kundnöjdhet

LEXION is the name of the largest series of combines made by the CLAAS factory in Germany. LEXION was introduced on the Swedish market 1996 and was for sale in Sweden from 1997. LMB have sold over 400 LEXION-combines in Sweden. In cooperation with the Swedish general agency we decided to make a market research on the Swedish LEXION-market. The questionnaire was supposed to give answers about capacity and technical equipment. Before I made the questionnaire I studied manuals and combines. I got 81 answers of about 325 questionnaires. That makes 25 % reply frequency.
