I dagens skogsbruk bedöms gallringsbehovet utifrån gallringsmallar som ger rekommendationer baserade på avvägningar mellan biologisk kunskap, ekonomiska faktorer och risker. Gallringsmallarna är anpassade efter tänkta produktionsskogar och kan således vara bristfälliga i andra fall. Därför behövs en effektiv bedömningsmetod som fungerar i både homogena och heterogena bestånd. Studier har visat att tallens (Pinus sylvestris) grönkronandel har påvisad effekt på diametertillväxten och genom att uppskatta denna kan ett direkt mått ligga till grund för bedömning av gallringsbehov, istället för det indirekta måttet grundyta, som nuvarande gallringsmallar är utformade efter. Tanken är att undvika produktionsförluster genom att gallra innan grönkronan hissats upp alltför mycket.

This report describes a comparative study about reading- and writing development in ?A-towns school? in The Gambia and in ?Villaskolan? in Sweden.The purpose of this study is to compare two teachers in Sweden with two teachers and two volunteers from the school in Gambia, with focus on their thoughts and methods on teaching reading and writing at each school and in their social context. The aim is also to observe and describe how classroom environment at both schools can encourage students to read and write.The theoretical base of this study is rooted in a sociocultural perspective but I have also chosen to illuminate behaviorism and cognitivism. The study is qualitative and the main research methods are interviews and observations of the classrooms.My conclusions are, even though considerable differences in approach and conditions, teachers in both schools work hard and show dedication towards their students.Another finding is that teachers use different techniques and working methods to achieve the same goal -to teach their students to read and write based on what is required of them in their cultural and social context. The different ways of teaching have been caused by the existence of different perceived needs based on culture and tradition.One conclusion is also that read and write requirements for students in the Gambia and Sweden are different from each other.

AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years).  ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

In this Master's Thesis a rhetorical analysis is applied to reading suggestions in the database Boktips.net. Boktips.net utilize the Internet for readers advisory by offering public libraries in Sweden to use and participate to its contents. The aim is to examine how library staff writes about literature in Boktips.net. The empirical material is delimited to reading suggestions on fiction for adults. Areas in focus of the analysis are rhetorical context, disposition, style and components from the point of view of content: summary, evaluation on portrayal of characters and setting, narrative, language use, genre and themes, entertainment, insights and external information.

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

In this composition, a study of consignment inventory on basis of the factors which are important for implementation and application of consignment inventory are made. Logistics chain from subcontractor to end customer is becoming more complex when the volume of items constantly increases to satisfy the needs of the market. From that perspective, companies had large inventories but today it is a lot of different solutions to streamline inventory management. One way that recently becomes increasingly common is to let the subcontractor fill up the customers stock using different approaches such as VMI (Vendor Managed Inventory). A further step in the evolution can be to make use of consignment inventory where the vendor owns the stock of the customer.

Each student in elementary school will under current policy documents have an individual development plan (IEP) from 1 January 2006. The plan should primarily aim for a higher goal achievement, but also to the student to gain a greater understanding of their own learning process and knowledge. My experience is that some students, despite efforts IUP have difficulty seeing their own learning process and it has been the starting point of my study. The aim of the study has been to investigate and analyze teachers work with individual development plans from the first grade to the sixth grade from a teacher's perspective. The goal was to identify strategies and techniques that could help develop IUP as a tool for the student's learning and understanding of their own learning process.

Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).
