Som små astronauter : -En idrottslärares berättelse om specialgymnastik i skolan
The aim of this work is to examine methodologies at remedial lessons for children with weak mobility, in a common Swedish municipal school in an attempt to determine if a connection to theoretical learning exists.Kadesjö describes how difficulties in concentration can arise as a result of problems with mobility and perception, and according to Piaget very young children develop cogitation through physical movements. These connections are not news but always current.At the meeting with Lasse the question was born whether learning problems in school that are a result of concentration difficulties, could be countered with mobility training.By the selection of Life history as method, it?s possible to follow a physical educator's experiences through his 30 years of work, and to some extent even his private life. Experiences and results are notified from a historical perspective from 1976 until 2006.He is bringing us on a journey that shows the changes in methodology and results after his contact with Sensomotoriskt Centrum..
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
Phycoremediation of pesticides using microalgae
Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and
mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity
in biosorbing heavy metals.
Konfrontationsbenämning av substantiv och verb hos svensktalande vuxna utan anomi
Confrontation naming is commonly used in speech and language pathology to diagnose neurogenic communication disorders and evaluate naming ability. The existing Swedish assessment instruments for adults consist of pictures depicting nouns. In this study, parts of the instrument An Object and Action Naming Battery were used, containing pictures depicting both nouns and verbs. The study?s purpose was to explore the degree of difficulty in the material, based on the naming of the participants, and examine whether different variables correlate with the results in confrontation naming.
Att få rätt stöd vid rätt tidpunkt : En observationsstudie av två barn med AD/HD-diagnos
The purpose of the study is to examine different situations and behaviors for students diagnosed with AD / HD and see if there are times where their diagnosis will be extra visible. This will ultimately see how and where these children may need support in their daily lives, and about the support they receive is relevant to their needs. Questions I intend to examine: Are there situations for students throughout the school day in which ADHD diagnosis becomes extra visible? If so, what situations? How is the diagnosis in these situations?It is estimated that about 3-6 percent of school children have AD/HD. It causes difficulties with concentration as well as impulse and activity control.
Att prata om, till eller med elever : En kvalitativ studie om lärares sätt att möta elever i svårigheter
To talk about, talk to or with children. A conversation between a child and its teacher should be more than the teacher telling the child what to do, how to act. It should be more like a respectful and reverent meeting between two people where the adult sets the tone. The purpose of this research is to investigate teachers' experiences of conversations with children in need of special assistance. Our issues: What do teachers say about how they meet children in need of support? How do teachers response to students who are in difficulty? What ability have teachers and their school's to meet children in need of support and what appear to be particularly important or problematic issues for them in that work? In order to find some answers to our questions we interviewed ten teachers at two schools.
Inokulmmängdens betydelse för utveckling av vetets stråbasröta orsakad Fusarium graminearum : utvärdering av ett biotest
Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.
Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry
Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land
management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC)
compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on
crops during drought.
The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to
study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.
Födointagets betydelse för muskelglykogeninlagringen efter arbete hos häst och människa :
Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.
Motorikens betydelse för inlärning
AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.
Växters förmåga att ackumulera metaller : Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm
AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.
En studie om styrkor och svagheter hos sudokulösande algoritmer
Sudoku is a popular game of logic in the form of a puzzle. Sudoku puzzles are printed daily in Swedish newspapers. The challenge of solving these puzzles have inspired many programmers to develop Sudokusolving algorithms. These algorithms use different approaches in order to quickly and efficiently solve the puzzles. One such approach is the use of logical strategies initially developed for human players.
Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag
The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.
Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri
In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.
