Förstärkning vid håltagning i betongbjälklag

Vad händer med en plattas momentfördelning vid håltagning? Vilka förstärkande åtgärder kan göras för att motverka dessa? Hur påverkar förstärkningsåtgärderna momentfördelningen jämfört med den ursprungliga fördelningen? Dessa är några av de frågor som har legat i fokus vid framtagande av denna rapport. Utifrån dessa tankar har en litteraturstudie av olika bjälklagtyper och förstärkningar genomförts. Detta har resulterat i en sammanfattning av de tre vanligaste bjälklagstyperna samt en rad olika förstärkningsmetoder. Dessa metoder är t.ex.

"Betyder det att han kastas i ruin eller att han inte kunde köpa hundra villor till?" : En receptionsstudie om hur pensionärer uppfattar ekonominyheter

Our thesis focus on how retirees perceive Tv4s news casts of economy news where we focused on five different aspects: What is the relationship between the news cast and the viewer and how does the viewer express their understanding of the news cast and the way it is constructed? What are the viewers attitude towards the news content and how do they find the news cast useful for them personally?We choosed retirees as our target group due to their vulnerable economic position in today?s society and TV as an important medium for them due to the digital divide. The study was performed with twelve qualitative interviews and one group interview where six retirees took part.We discovered a big interest for economic news in the target group. The majority had a sympathetic view of the news cast they saw but they also expressed skepticism toward the economy segment and/or news castings. The majority expressed a lack of trust for the journalists and the experts brought in to share observations and make announcements, and the financial business overall.

Självkompakterande betong

SKB har funnits i världen från sent 80-tal men till Sverige kom den först på mitten av 90-talet. Idag utförs endast 10-15% av alla gjutningar med SKB vilket jag tycker är konstigt med tanke på alla fördelar som finns med denna betong. Detta examensarbete tar upp fördelar och nackdelar med självkompakterande betong kontra traditionell betong..

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.

EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Självkompakterande betong vid platsgjutning av anläggningskonstruktioner

By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

Tid- och kostnadsanalys av innerväggar

In our thesis we will compare interior walls, both bearing and non-bearing. All of thewalls analyzed are currently used in production by Skanska Construction, who is alsoour employer/supervisor for the project. The different wall types will be comparedfocusing mainly on time, cost and workability. All of these walls aside from the nonbearingwall are constructed using concrete, either prefabricated or cast on site..

Warden i Israel : En studie av Wardens tillämpning i Israels luftkrig 2006-2009

Den amerikanske luftmaktsteoretikern John A Warden III har skrivit ett flertal artiklar och böcker om vad han anser är det bästa sättet att använda luftmakt. Warden förordar luftmaktens offensiva natur och eftersträvar ett snabbt, för egen del, fördelaktigt slut på en konflikt. Warden har bl.a. liknat fienden vid ett system, där han menar att strävan skall ligga i att slå ut fiendens ledarskikt vilket får tillföljd att dess vilja till strid upphör.I detta arbete ges en sammanfattning av, enligt författaren, centrala delar av Wardens teorier. Sammanfattningen mynnar ut i tre stycken parametrar som kommer att utgöra Wardens teorier i detta arbete.

Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter

AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.

MUSIK TILL GUDS ÄRA - SYNDIGT ELLER GOTT? : En studie av kvinnors musicerande i den tidigkristna kyrkan

This thesis aims to investigate and discuss the possibility for women in the early Christian church to make music, which in the ancient Roman society was something complicated. Afemale musician was looked upon as decadent and dissolute. This idea, in combination with the music ideals of the church influenced by the Neoplatonic movement, and the Pauline statement (1 Cor. 14:34-36), cast women to be completely prohibited in participating even in the psalmody during the service. My purpose is to discuss how this was looked upon in different Christian regions, using the church fathers as the main material source, since this has not previously been well documented or studied..

"Rabarbers" - Processen med texten

The essay is an analysis of the theatrical and dramatic aspects to a playtext. Based on the production and manuscript Rhubarb by Maria Blom.With the essay I intend to answer the following questions: What happens to the manuscript Rhubarb during the transformation from being a dramatic text to becoming a theatrical text? What are the similarities and differences between reading a manuscript and watching the performance of a play?The essay is based on literature, two interviews with Maria Blom and the manuscript to Rhubarb by Maria Blom. Besides two versions of the script I also had the opportunity to watch videotaped material from the original production. And I compared the original cast of Rhubarb with twoamateurproductions of the play..
