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.

Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU

In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

Prevalence of subclinical mastitis and udder pathogens in small holder dairy farms in Mapepe, Batoka and Choma areas in Zambia

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

Produktionsvåtmarker mot övergödning

In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

Småskaligt vattenkraftverk i Nyköpingsån

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning

To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.

Careful preparations are also important and the right form of field studies.

Den svenska varmblodiga hästens avelsmål : en enkätundersökning och analys av genetiska trender

As the quality of internationally competing horses is increasing, a debate concerning the breeding goal of the Swedish Warmblood horse has arisen. Some people claim that the breeding goal should be divided into two separate goals in the future; one for show jumping horses and another one for dressage horses. At the same time others claim that since the largest group of people using the Swedish Warmblood horse today is amateur riders, the needs of these riders should be taken into a larger consideration in the breeding program. The largest emphasis in this matter is on the horses? temperament. The objective of the study was to investigate what the majority of the Swedish horse people think about a variety of questions concerning today?s breeding goal of the Swedish Warmblood horse.

Behövs en litterär kanon? : Jämförande studie baserad på sju gymnasielärares syn på kanons plats i svenskundervisningen 

English title: Is a literary canon necessary? A comparative study based on seven senior high school teachers´ different approaches towards the place of canon in the education of Swedish. The purpose of this study is to describe and analyze how seven senior high school teachers relate to a literary canon in Swedish while teaching literature in senior high school, identifying similarities and differences among the teachers? view and opinions about an outspoken formal literary canon and a silent, informal canon.The earlier research opens the door slightly to the American debate and gives insight about the complexity of the concept of canon. The study continues with exploring possible relations to postcolonial theory and didactics.    The study reveals that the majority of the concerns against canon are that too much centrally governed education may decrease the motivation and commitment of the teacher. In addition, the dominant canon passivizes a certain variety of literature, thus various points of views. On the other hand, views on the equalizing effect of canon on the level of education and its benefits in increased knowledge of the history of the literature are salient. .
