Möjlig bronsåldersboplats? : en undersökning av platser från bronsåldern på Gotland

There are none known Bronze Age settlement on Gotland, although there are severalexcavation reports that mention that they have found a probable Bronze Age settlement. In the excavation that have been done in the study areas, there are Bronze Age dated hearths, cooking pits and post holes. These study areas have been investigated if they might be possible Bronze Age settlements. This paper discusses about the criteria of settlements and also investigate if the study areas meet those criterias. There are many different criteria for settlement but only the criteria of FMIS are used in the study.

Betong - Förvånansvärt lättflytande!

Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete. Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe. Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength. The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved. After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..

Skiftarbetets påverkan på den upplevda stressen : - en undersökning inom vården

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .

Karaktärisering av Gremmeniella-skadade bestånd inom Holmen Skog AB :

Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

Mognad hos unga flickor : normbrytande beteende, alkoholvanor och sexuellt beteende.

The aim of this study was to examine if biological early maturing girls and girls that percieved that boys treated them as older than they actually where drank more alcohol, were more delinquent, had more romantic relationships and sexual intercourse. Our data was collected from seven schools in Sweden. Significant relationships where found between early maturation and all four dependent variables. Significant relationships could also bee seen between how girls perceived that boys treated them and alcohol use, romantic relationships and sexual intercourse. For two of our dependent measures we found week interaction effects, for girls biological maturation and there perception of how boys treated them according to there age.

Skola i förändring : Politisering och företagisering av en kommunal och en fristående gymnasieskola

In this essay I examine how a municipal- and an independent upper secondary school compare to the ideal types the Company and the Political organization and how that affects the school practise as it?s described in policy documents. The conclusions are that the municipal school on a number of variables correlate to the ideal type the Political organization. At the same time the school reforms of the 1990s are considered as an intention to ?companylize? the municipal school and a number of tendencies how that have affected the municipal school are shown.

Kränkande beteende på arbetsplatsen : Hur definierar vi kränkande beteende och vad är avgörande för vår definition

Earlier research has shown the difficulty of defining insulting behaviour in the workplace. It has been noted that the individual and subjective definition is connected to the specific situation in which the potentially insulting incidence occurred. In this study we designed a quantitative questionnaire in order to hopefully elucidate the comprehension of insulting behaviour and furthermore enable a more in-depth investigation on how important the contextual meaning is. This study examined 140 (n=140) working adult?s attitudes towards insulting behaviour in the workplace and the importance of the contextual variables.

Från retailer till e-tailer: En studie av konsumentattityder

With the fast development of Internet and the e-commerce during the last decades, retailers are now introducing online stores. This has been adopted as a common strategy within the industry and the phenomenon seems likely to increase over time. Theory based on brand extension is used in this study to explain the effects on brand attitude and the link with willingness to pay when a traditional retailer introduces an online store. We execute an experimental study in order to investigate the effects where we use the offline- and online channel as well as two brands with different strengths as independent variables. Results show that brand attitude and its link to willingness to pay transfers to the online channel.

Planering i staden. Hyllie stadsdel- från stagnation till integration?

This thesis deals with urban planning in connection with social and spatial integration.It´s a study of a new planning project in Malmö in southern Sweden. It´s an interesting case because this new, fashionable area will be located next to areas facing socio-economical challanges and stagnation. By using two theoretical models I analyse how the visions for planning a city are formulated and applied when policy is going to be operated. My models are ?the balanced community? and ?the dual community? .The conclusion is that the focus for Malmö and Hyllie is going towards emphasing the creation of attractive but segregated districs in a city.

Hållfasthetssortering av plankor med hjälp av röntgendata

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.
