Detta examensarbete, på uppdrag av Atlas Copco Rock Drills AB, syftar till att kartlägga de problem gällande vibrationer som finns och uppstår vid användandet av produkten Scaletec MC och komma med förslag till lösningar på ett nytt system som bättre hanterar vibrationer än det befintliga. Lösningarna är avgränsade till hytten och hyttens koppling mot ramen. Kartläggningen av Scaletec MC visade att den största problemskaparen är den långa bommen med den tunga hydraulhammaren framtill. Den skapar rörelse i hytten både vid skrotning och vid transport. Vid transport är även den odämpade stolen, de ojämna vägarna och det faktum att axlarna är stela ett stort problem som genererar helkroppsvibrationer hos operatören.

The main objective of this study was to evaluate animal welfare situation in Ethiopia during slaughter and to investigate chain activities between animal markets and Kera abattoir in Addis Abeba. In total, 442 animals were observed within 52 groups of cattle; both ox and calves with different breeds. The study was divided into four different sets of data collection; behavioural observations, recording of slaughter process, observation during transport and interview. During the behavioural observations, an ethogram was used with 46 behaviours observed, categorised into 5 different groups. The data was calculated using Excel and SAS. The results indicated that a significant correlation (p-value.

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

This study has been carried out at Södra´s 31 local forestry districts and within six plant terminals. The production and sale of seedlings at Södra is managed in collaboration with ?Södra Odlarna?. Approximately 35 million plants are cultivated each year, providing Södra´s members with a wide choice of high quality plants. The seedlings are nurtured at nurseries before transferred to plant terminals where they are stored and watered.

The aim of this study was to investigate how preschool teachers think about preschoolscience, what they consider science to be and how they deal with specific curricular objectivesrelated to science.Science is a part of our everyday life, it is a prerequisite for understanding everydayphenomena and how the world is working. Nevertheless it is often dropped in favour of othersubjects in Swedish preschools.The eight preschool teachers participating in this study are all working in the samemunicipality in the western part of Sweden with children aged 1- 5 years. The method used inthis study was interviews. The interviews were recorded to facilitate the transcriptions.The results show that preschool teachers find that science is an important subject that shouldbe introduced to the children early on in life. They also show that preschool teachers considerscience to have a preventive effect on the learning to the children, and it is needed for them tounderstand everyday processes and phenomena.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

During my education I have frequently noticed that pupils do not like science or find it hard and dull. The purpose with this investigation is to find out how pupils experience their science education and if they can understand the arguments for studying the subject at school.I have made a questionnaire study among pupils in grade 8 and 9. After analyzing their answers I have interviewed some of the pupils to get answers on further questions.The investigation resulted in conclusion that pupils have hard to connect their science-education to their everyday lives. The most important element in forming the pupil?s opinions about science is their relation to the teacher and how the lessons are set-up.The following questions will be answered in this paper:Do pupils understand why they have science at school?Can the pupils see the use of scientific knowledge in their everyday life?How do pupils look upon their science education?.

This study describes how the women lived with breast cancer. The purpose with this study was to describe the womens' view on the disease and the understanding they hade on the social support they were depended on. The method was a study of literature with article reviews according to Polit et al., 2001. As theoretical frame of reference we choose Carnevalis model, Everyday life -Functional state of health. The result showed that the following four groups were formed: Support, positive and negative support off nursing staff and significant others.

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

The society of today can?t manage without transportation. We need transports to getfood, to go to work and to create new products. The transportation ofgood is thus an important part in the function of the society and they?ll increase, bothin number and in amount.

Women today feel that their urban surroundings are unsafe, and because of that they use different strategies to reduce the risk of being exposed to criminal acts towards them. The focus of this study is to develop an understanding of the insecure feeling that women feel and what that feeling might originate from. By using previous research and theories we have been able to incorporate a gender perspective on the study this because the gender role is central to understand women?s feelings of insecurity. The purpose of the study was to develop a deeper understanding of women?s sense of safety and insecurity.The central questions of the study are1.

To integrate environmental concerns into non-environmental policy making has become an important policy objective within the European Union. This essay investigates policy instruments in use to achieve environmental policy integration in the EU's transport sector respectively fisheries sector. The point of departure is a theoretical discussion about governance and the use of different policy instruments for environmental management at the EU-level. The focal point is the argumentation that regulatory policy instruments alone cannot achieve environmental policy integration satisfactory. By using Jordan et al's classification of so called "new" environmental policy instruments (market-based instruments, voluntary agreements and ecolabels) as complements to regulatory measures, the essay investigates whether the first-mentioned are used within the two sectors.

During pre-slaughter handling of pigs the animals are often subjected to methods that induces stress and are a threat to the wellbeing of the animals, such as mixing of groups, loud noise and transportation. A new law will be implemented in 2006 in Sweden that prohibits mechanical noise exceeding 65 dB in abattoirs. The purpose of the research presented in this paper was to examine the effects of noise and transportation on pig behaviour. The activity and aggressiveness of the pigs were examined with behavioural studies during transportation and during three different noise levels: 55, 75 and 95 dB. Before the noise treatments took place the groups were mixed and half of them were transported for approximately 2 hours. In the study 432 pigs were used.

The aim of this study is to look how the Social Service has handled custody issues.
