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.
Gymnasieungdomars känsla av sammanhang och fysisk aktivitet - finns det ett samband?: en kvantitativ studie
Background: Physical activity is important to sustain your health, but there are also other factors which can influence health. One of them is the degree of sense of coherence. Aim: The main purpose of this study was to examine if there existed a correlation between amount of physical activity and degree of sense of coherence (SOC) in adolescents in the northern parts of Sweden. This study also dealt with differences and similarities between and within the whole examination- group and subgroups. Methods: A SOC- questionnaire with 29 items, developed by Antonovsky, was used.
Hemtjänstpersonalens upplevelser av sitt arbete
Purpose: Our aim is to get an insight on how home care workers experience, handle and looks upon their work. We also want to form an opinion of how home care workers experience the relationship to the clients they meet.Questions: How does home care workers experience their daily work with their clients? Home care workers daily meet many different sorts of clients with different needs, how do they handle this? What kind of support does home care workers get in their work?Method: A qualitative design with semistructured interviews.Conclusion: The most central conclusion from all of our interviews were: that home care service workers has a very stressful and demanding occupation, that the work has a low status, that the personnel has a big responsibility for the wellbeing of other people and that they often find their work satisfying and fun. To have someone to talk to and exchange ideas with was also mentioned by the informants as a vital part of feeling support in their work. From the Antonovskys theory, a sense of coherence, and Goffmans views of the society, we also find that the larger part of our informants feel a high sense of coherence and that when they have to adjust to their different caretakers they play different roles..
Hörapparatbärares upplevelser och erfarenheter av tekniska hörhjälpmedel i offentliga lokaler
To be able to feel a sense of belonging, people need to have the possibility to take part of the information from the society. Hearing-impaired don?t have the same possibility as hearing people when they want to take part of the information, therefore they don?t get the same benefit. This contributes to a feeling of not belonging and a sense of limitation in different social occasions. Therefore the society needs to be accessible to everyone regardless disability.
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.
Breed differences in natriuretic peptides in healthy dogs
Measurement of plasma concentrations of natriuretic peptides have been suggested to be of diagnostic and prognostic value in canine cardiac disease. In several previous canine studies, however, a considerable overlap between investigated groups has been identified. A reliable natriuretic peptide test for use in clinical practice requires establishment of reference values for natriuretic peptides in healthy dogs and cut-off values for subclinical disease as well as for clinical signs of congestive heart failure. Numerous physiological, pathological and pharmacological factors, aside heart function, may influence concentration of natriuretic peptides. A potential effect of dog breed on natriuretic peptide concentration has been suggested but has, to our knowledge, not previously been specifically studied.
Målstyrning via policydokument Garanti för rationalitet och effektivitet eller symbolpolitik för meningsskapande?
The aim of this thesis is to develop two idealtypes of politics to help serve as instruments in understanding and analysing the view on politics held by top civil servants in the municipality of Lund Sweden. The two ideal types developed here are symbolic sense making politics and rational instrumental politics. These two ideal types were applied to material from a qualitative survey to help bring out clear results and to help with the interpretation of the material The results of the study showed that the two idealtypes could not help to clearly categorize the civil servants views on management by objectives. But while categorizing the top civil servants views the important features of policy documents the ideal types were helpful. By using the ideal types I came to the conclusion that the view on policy documents was mainly characterized by sense making politics.
Inventering av bergborrade brunnar för dricksvatten i område med risk för salt grundvatten : en utredning av grundvattensituationen i Vreta-Ytternäs i Uppsala kommun
The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.
Perfluoroalkyl substances in Arctic birds : a comparison between glaucous gulls and black guillemots from Svalbard
Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.
NATO:s luftkrig i Kosovo utifrån Wardens teorier
John A. Warden III is one the most mentioned air power theoretic of his time.He has written a number of theories concerning air power and the best way to use this to win wars.The author of this paper gives a short resume of what he consider are the central thoughts in John Warden´s theories. These thoughts result in four factors; Enemy as a system, centre of gravity, parallel attack/concentration and finally air superiority. These factors are then being used to inves-tigate if NATO used Wardens theories during the Kosovo war in 1999.The reason for the author to choose the Kosovo war specifically is due to the fact that NATO during the war only used air power as an instrument to get Serbia´s president Milosevic to the negotiation table but also the fact that this would turn out to be quite a challenge for NATO.The conclusion is that out of the four factors only one is traceable throughout the entire operation, and that is air superiority. Regarding the other three factors they can only be found in parts of the operation..
