Gäddan & fisket i Ringsjöholm : en osteologisk metodstudie i säsong & bevarande

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) Size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the Size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :

Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance. As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.

Kostnadskalkylering på Banverket

The purpose of this thesis is to analyze and propose improvements to the current procedure for cost estimations of purchased maintenance work at Banverket, the Swedish rail administration. This governmental institution is responsible for the procurement of maintenance services for the country?s railroad network through open tenders. Due to the generally low number of contractors, it is particularly necessary to establish accurate cost estimates in order to assess the offers and ensure that a fair price is being paid to the suppliers. Several flaws associated with the current practice are identified and analyzed according to cost accounting theories.

Barngruppens storlek i förskolan ? en kvalitetsfråga? : Sex pedagogers reflektioner

This research is about six pedagogue´s and their reflections about the size of the children´s group in the preschools. Then I will discuss the pedagogue?s recommendation on the significance of the size of a children´s group learning and development and it´s practical significance for the preschool function. The pedagogue?s statements will be discussed in relation to The Swedish National Agency for Education (TSNAE) guidelines on group size.The theoretical framework of this essay will take an overview of the social cultural perspective, the group size and its significance for both the children´s learning and development, for interaction and communication and TSNAE advice and guidelines.

Svenskar skattar ingruppens egenskaper lägre i närvaro av en utgruppsrepresentant : en studie av ingruppskorrektion

Psychological research concerning correction of stereotypes has mainly focused on how individuals adjust their negative attitude towards the out-group due to the apprehension of appearing prejudiced in front of out-grouprepresentatives. This study though, does not deal with estimations of the qualities of the out-group; it deals with estimations of the qualities of the in-group. Does Swedes correct their estimations of their own group when the experiment leader is of another ethnicity and has a different colour of skin? The participants were students at Halmstad Högskola and they were all born and raised in Sweden. Half the participants got to meet a Swedish born, white skinned experiment leader, whereas the other group got to meet an African born, dark skinned experiment leader.

Textstorlekens påverkan

Purpose;the purpose of this study is to investigate whether a product ad observer's purchase intention, perception of product quality, brand image perception and price perception is affected depending on the size of the text that was used in the ad to communicate the product price.Methodology;the study was conducted using a quantitative method through a survey. The implementation of the study has been done by using three variants of the same suit ad where the three different variants have been manipulated on the text size on the price information, by reduced / increased the text size. The implementation has also been carried out using two different ad sender, with three ads for each sender.Result and conclusion;the text size on the price of a product ad mainly affects the observer's price and quality perception, where the small text will have a positive effect on quality perception and a negative effect on the quality perception. Even brand image changes depending on the text size where small text will have a positive effect..

Kostnadsbesparingar på EM7 : Omkonstruktioner för billigare tillverkning

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

Äggstockens normala storlek och struktur hos tik :

There are only a few published studies on the normal variation in ovary size in bitches. All of the previous studies have been made on the beagle breed. This study was performed on indian street dogs with the objective to measure ovaries and structures in the ovaries after ovariehysterectomy to decide if smaller dogs have smaller ovaries and how small and big they can be in the normal dog. The structures (follicle and corpus luteum) where also measured to get a maximum size for normal structures in the bitch. This information can be valuable when examining the ovaries of the bitch with ulstrasound.

Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek

The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

Hassel (Corylus avellana) som indikator på markanvändningshistorik

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.
