This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.

The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the Difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant Difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

Abstract Aims and objectives. To examine whether an intervention with carbohydrate- counting at onset of type 1 diabetes in children, has had any effect on metabolic indicators such as HbA1c , BMI-sds and total daily insulin / kg, 2 months and 1 year after onset by age and gender .Background. The pediatric department at the university hospital of Norrland in Umeå (NUS), has since several years a higher average HbA1c among children 0-17 years, compare with pediatric departments in the rest of Sweden.  Therefore, in autumn 2011, an intervention was made to teach children with diabetes and their parents to count carbohydrates from the onset of diabetes. Using this method they can regulate their insulin doses depending on the amount of carbohydrates they are eating.Design. This is an empirical registry study done on the basis of a quantitative method.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any Differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a Difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.

This thesis attempts to describe the application of variation theory, as developed by Ference Marton, at a Swedish primary school, intermediate level. The aim of the thesis was to investigate some aspects of a learning process. The students were introduced with the theme of ?sustainable ecological development?. This included theoretical and practical knowledge of the art of sustainable living.

SummaryHerbal remedies have been used for many years to alleviate various symptoms. They were used in ritual acts to reassure the Gods and as medication. Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.

Abstract The purpose of the study is to examine how children perceive the relation between play and sex and analyse it from a gender perspective. This by answering the questions: "Is the children?s choice of place, materials and company in play dependent on gender?" and "Is there a significant Difference between the sexes and/or ages?" The study was done through twelve focusgroup interviews with three children in each group except two groups of two children in each. Eight boys and nine girls of six years old and nine boys and eight girls of nine years old were interviewed. Boys and girls were interviewed in separate groups and the questions were open ended and followed up.

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.

Lip force has been found to affect the ability to achieve satisfying speech production and swallowing. A normative value for lip force in adults has been measured to 15 Newton (N). Corresponding value for children measured with Lip Force Meter 100 (LF100) does not exist. In the current study lip force was measured in children between the ages of five and ten years. The aim of the study was to obtain normative values for children with typical development in separate age groups.

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The Differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

The fast developments in information and data technology during the recent years have accentuated the need for the business manager to interpret and act on information from the surrounding environment. Today we know little about what information is really used in the unique decision-making. Further, little is known about how information should be designed to fit people with a more intuitive approach to interpreting information. This study is therefore about the Difference between peoples approach to interpreting information and how information should be designed to fit those with a more intuitive approach to interpreting information. The application is made to dairy farms in Sweden. The literature review describes the strategic leadership, the decision-making process and the intuitive and the analytic thinking.

The study aims to describe and analyse the relationship between norm and practice regarding social services casework on honour-related problems. The relationship between norm and practice involves the Difference between the way it is intended that social workers shall operate in these cases and how they perceive that this works in practice. We interviewed two focus groups of eight Swedish social workers, four in each group. We also held an individual interview with a social services business developer. Focus group interviews were based on two vignettes; one depicting an honour-related case and the second an "ordinary" case.
