Varför lyckas inte alla? : En studie på Hantverksprogrammet Frisör och Florist om skillnader mellan hög- och lågpresterande elever.
Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.The results of our study indicate that there were clear differences between high-and low-performing students.
Individualiserad matematikundervisning : en kvalitativ studie om lärares arbete med individualisering i förhållande till högpresterande elever
The purspose of this study is to investigate how teachers are working to individualize mathemathics education relative to high-performing students and how they define the therm individualization. According to the Swedish curriculum the teaching process should be based on the students prevoius knowledge and experiences. The teachers should in their preperation take every student in to consideration. To be able to investigate these subjets I prepared following questions:What does the concept of individualization in mathematics mean for the teachers?What does it mean to work with an individualized mathematics teaching?How does teachers individualizes teaching mathematics relative to high performing students?This study is based on a qualitative method with both interviews and observations.
Biologiska behandlingsmetoder för rening av rejektvatten från biogasproduktion
In this literature review the characteristics of two free-floating macrophytes, water hyacinth (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

Tätortsklassificering utifrån servicebredd och servicegrad : En klusteranalys av Sveriges tätorter
Statistics Sweden is an administrative agency that delimits built-up areas and produces statistics regarding them. The statistics provide information about the area of the built-up areas, their population number, number of gainfully employees working in the built-up areas, and of buildings. Now Statistics Sweden wishes to extend such statistics by producing a measure regarding how well developed the service is in each built-up area.This study is a contribution to this statistical improvement work and the purpose is to ? by employing geographical information systems and cluster analysis ? classify the Swedish built-up areas according to 1) service width and 2) service degree. A particular built-up area has a high service width if it has many different service functions, such as pharmacies, schools and grocery stores.
Kvalitet i brödvete :
The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.
Fallstudie : Egen foderberedning till slaktsvin :
The purpose of this examination work was to make a general description about drying and
storage of grain, and a case study with a comparison between brought and home-made feed.
The case study was made on the farm Solhem in Hörby, a farm that produces 3870 pigs for
slaughter a year.
In this project three alternatives have been compared, 1st alternative: own produced grain
approx. 400 ton + wet grain 415 ton purchased during fall, 2nd alternative: own produced
grain approx. 400 ton + dry grain 415 ton purchased during winter, 3rd alternative: bought
feed 815 ton purchased continuously during the year.
Considering the price information provided to me the 1st alternative gave the cheapest feed..
Syntes av hydroxyapatit/ nanocellulosa kompositer
Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.
Health Locus of Control och impulsivitet i relation till träning : en studie om universitetsstudenters träningsbeteende
There are many aspects which must be taken into consideration when studying individuals? need of exercise. The study investigates if impulsivity and Health Locus of Control affect the continuity of physical practise. The main presumption was that individuals with high impulsivity, high Powerful Others and high Chance Health Locus of Control, would have a significantly harder time to maintain a continuous physical activity. The survey used two standardized tests to measure impulsivity and Health Locus of Control and in order to be able to measure the insensitivity and the periodicity of physical exercise, a test was developed by the authors.
Review of the litterature and an attempt to evaluate intake levels of iodine and selenium in dogs with and without lymphocytic thyroiditis
The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.

High-rise buildings; structural design, prefabrication and logistics
In the report we have investigated four high-rise buildings with the intentions to find out witch parts are prefabricated and what relation can be found between structural design, prefabrication and the logistics. After the investigation we noticed that the grad of prefabrication in each one of the projects is good in relation to what purpose the building have and the given background. During the report we found that layout ? structural design ? prefabrication ? logistics is an order that we think can make the production of the building more effective if followed. We believe that the prefabrication of high-rise buildings have potential to grow and get more optimized in the future..
Frånluftsvärmepumpens möjligheter i flerbostadshus
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.
Hur kan bra bli ännu bättre? : Hur lärare jobbar med att leda och motivera högpresterande elever.
The purpose of this paper was to investigate how teachers work to lead and motivate high-performing students, and how these students were defined. The method used was qualitative, more specifically an interview, which was then analyzed with a thematic analysis. Six teachers participated in the survey, and what emerged was that high-performing students were often ambitious, structured and social students. High performing students were also characterized by the fact that they needed challenges, attention and positive feedback on their performances, otherwise they ran a risk of not performing. Structure was also important for the teachers themselves, that they had a goal when teaching and a way of achieving that goal.
Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor
To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.
