Hallsta Pappersbruks virkesförsörjning
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.

Utökning av mätområdet för turbinverkningsgraden på avgasturbo
The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

Kalcium- och fosforsmältbarhet hos växande hästar
In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing
horses were increased with 35 and 25 %, respectively, based on results from a Canadian study
showing that daily endogenous fecal losses of Ca and P were greater than previously
suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true
absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is
assumed to be higher for growing horses because their diets are often supplemented with
inorganic P. Thus, an efficiency of 45 % is used for growing horses as compared to 35 % for
mature horses.

H?RNERVMOSSANS P?VERKAN P? LJUNGHEDENS ARTM?NGFALD: En f?ltstudie fr?n Sandsj?backas naturreservat
Campylopus introflexus is a moss species that originates from the southern hemisphere and has spread worldwide during the 20th century. Today it is classified as an invasive alien species in many countries, and it has been seen during inventories that it has become widespread in Sweden as well. The purpose of this essay is to contribute to new knowledge about how this moss affects species diversity on Calluna heathlands in Sweden. The study includes both fieldwork and an analysis of scientific literature on the subject, and the question that is answered is if C. introflexus has an impact on species richness in the heather peat.
Vilometabolism hos barn och ungdomar med Cerebral Pares : En deskriptiv korrelationsstudie
Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).

Varför barn fortfarande vräks : En kvalitativ jämförande studie om socialtjänstens användande av disciplin i ärenden där barn riskerar att vräkas
The purpose of this study was to examine whether the degree of discipline in social services may be the reason why more children are evicted in one municipality in Stockholm, compared to another. Since our purpose was to study the degree of discipline in social services work with eviction cases where children are concerned, discipline is therefore a central part of the study. The interest in the subject arose from our prior understanding that social services approach to discipline may affect the extent of evictions. In order to answer the study?s question at issue, a qualitative interview was conducted to create an understanding of the discipline and a vignette study was conducted to compare the social workers assessments in two municipalities in Stockholm, Högstad and Lågby.
Automatic registration of dairy cows grazing behaviour on pasture
Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.
Vibrationsdämpning av värmepump
Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

Film- & Litteraturturism : Fakta och fiktion i en lättsam blandning
Movie and literary tourism is a genre that has been recognized around the world for a long time but that has only recently got a grip on Sweden. More and more famous books are being cinematized and because of the success of these movies we can now walk in the traces of Wallander as well as the Millenniummovies.The focus of this study is mainly about the tourists? motivation when it comes to this form of tourism and the purpose is to try understand what needs come in to play when a movie and literary tourism attraction is chosen. The study objects are two movie and literary walks which are based on books and movies with a fictitious storyline.The performed research was based on a multiple strategy with the qualitative method - consisting of respondent and informant interviews - in focus and the quantitative investigation - in the form of an one-page questionnaire - more as a complement.On the basis of the most fundamental theory of motivation in general (Maslow, 1970) and the tourism research?s more specific travel motivation theory (Pearce, 2005), the conditions for movie and literature as sorts of tourism have been made clear.
Vad innebär planeringstid? : En kvalitativ studie om fyra förskollärares syn på den pedagogiska planeringen i förskolan
The running of a Swedish pre-school is not just about taking care of children but involves incorporating educational activities that follow curriculum guidelines. In addition, time must be allocated for planning, discussion, evaluation and reflection. Many pre-school teachers feel that there is insufficient planning time which is needed to follow the established curriculum guidelines for kindergarten. Due to the rising numbers of children per class, and the obligation to document and evaluate everything, pressure and lack of time has become a significant issue.The purpose of this study is to investigate four pre-school teachers´ views on pedagogical planning and reflection time. Questions to be answered include:1.
