Volvo Construction Equipment is a world leading company in construction machinery. Tomaintain the best products, development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the pressure ripple is reduced when the paralleled hydraulicpumps are phase shifted and reduces each others pump pulsations.

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.

The purpose of this study was to illustrate the effects of music in pre-, peri-, and postoperative care. This study is a systematic literature study based on 22 scientific articles with quantitative methods. Music is an alternative treatment used in nursing care. Nurses could as a complement to routine pre-, peri-, and postoperative nursing have music interventions in mind, because an operation involves anxiety, fear and pain for many patients. The result of the study shows that music can reduce patients? anxiety, pain and improving their wellbeing and recovery.

Kisa Courthouse in the south of ?sterg?tland is a house built in the early 19th century with a typical neoclassical style. With clearly regular symmetrical wooden facade scheme with a central main entrance. The main entrance is a wooden double door with richly decorated portico. the crown moulding above the door consists of a band of dentils with a cornice moulding at the top.

A game designer has to consider several aspects when he or she is designing a game. One of those aspects is the perceived freedom in the game by the player. There exist several methods to facilitate this perceived freedom in the design phase of the game. This thesis presents, in a qualitative methodology, a number of these methods a game designer might utilize to give the player a heightened sense of freedom for an improved gaming experience. Included herein are such elements as indirect control, linearity, storytelling and level design..

The Innovation- and Design Engineer program at Karlstad university is a three year long engineer education. In the last phase a final piece is to be done and in this case Boda Borg in Skellefteå is the company in need of product development. Boda Borg is a company in the experience industry and they are located in nine cities from Gällivare in the north of Sweden to Karlskrona in the south. Boda Borg is a franchise company where every facility is their own. As a visitor you will experience physical challenges as well as intellectual in adventure rooms which are serial linked.

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

En kvalitativ socialpsykologisk uppsats med syfte att belysa betydelsen av gemenskap och detsociala i missbrukares process av tillfrisknande. Det empiriska materialet grundas i tio nyktramissbrukares livsberättelser, med vilka vi kommit i kontakt med genom organisationen VågaVa. Parallellt med vårt huvudsyfte vill vi också spegla denna stödorganisation. Den övergripande analytiska ramen diskuterar social aktivitet, etik, gemenskap i förhållande till kampen mot missbruket, vi lyfter även fram vikten av stöd- och samtalsgrupperna Nyktra Narkomaner och 12-stegsprogrammet. Teorierna som appliceras på materialet är R.

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.

I work on a lighting design for a dance performance to be on tour. A lighting design adapted for three different conditions was made: - One comprehensive where I allow myself a great deal of creative freedom, adapted for the stages with major technical conditions. - One smaller version for stages with less equipment and with less time for preparation on site. - One design for very simple conditions. I also examine the specific differences between typical theatrical lighting design and typical dance lighting design, and the best way to prepare for the hands-on stage design phase..

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.

The purpose of this master thesis is to examine how the relationship between humans and nature is expressed in the imaginative literature. My aim is to identify ideological reproductions in the analyzed works. Therefore I have chosen one work from late 19th century and one from late 20th century. This makes it possible to examine the contextual anchorage of the found ideological expressions. The study?s theoretical framework is primarily based on ecocriticism, and especially on Greg Garrard?s and Kate Soper?s thoughts.

Forest ebeaver is, equipped as a bio-energy harvester, approximately four and a half meter long and weigh just over two tons. The main purpose of this report is to find out whether a small machine like Forest ebeaver can be profitable used in early thinning. To find this out a study has been made using the machine to thin in a young pine stand..
