Turismutveckling av en landsbygd : - En studie om landsbygders utvecklingspotential inom turismnäringen
AbstractThe tourism industry has evolved to a vital factor for destination development in rural areas. This study aims to see how the tourism industry can be seen as an opportunity for development in rural areas. To be able to develop, rural areas have to be restructured and this study presents the restructuring problems that rural areas usually face and how developing tourism can be seen as a solution to these problems. Five destinations of rural character have been investigated in this study in order to see how these restructuring problems are expressed and addressed through tourism. A key example has been used to provide a clearer image of how these problems and tourism are related to each other and how their interaction can create a positive development for rural areas in Sweden..
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.
Ligger grunden till problem inom projekt i initieringsfasen?
Project management has been a very popular way of conducting information system development in the past years. Among all major information system developing companies today, almost everyone work in some form of project management. Our objective with this study has been to find out if there are any problems that begin in the early part of the project. Problems that, if they aren?t solved directly, can become bigger problems later on in the project.
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.
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.
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.
Att söka samhällsinformation. En användarundersökning
Citizenship information is defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
Vuxna dyslektikers informationsbeteende en undersökning av hur sex personer med dyslexi hanterar informationsproblem
The aim of this Masters thesis is to describe the information behaviour of six adults with dyslexia with focus on how they handle information problems. The data consists of literature and interviews with six persons with dyslexia. The theoretical framework used in this study is Anders Hektors theory about human information behaviour as well as concepts and theories from the library and information science field. Ten information activities are used to describe the informants information behaviour. Answers are sought to the following questions: · How do the informants describe their backgrounds and their reading- and writing disabilities? · What problems do the informants meet in the context of information in their everyday lives with reference to ten particular information activities? · How do the informants solve these problems? The study showed that the main problems for the informants appeared to be difficulties with reading and spelling, problems with the appearance of the information, lack of time and stress while reading and writing as well as problems with lack of awareness about dyslexia.
Digitala objekt i neutralt format
Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.
Ekologisk slaktgrisproduktion i Sverige :
This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.
Etableringsproblem på den ryska marknaden : Svenska företag i Moskva och Sankt Petersburg
In this essay we map and evaluate obstacles and problems that can occur during the establishment of international companies in Russia. This is done by investigating Swedish companies, which are established in Moscow and Saint Petersburg. We used secondary and primary data from books, previous surveys, reports, articles and the Internet. We also interviewed the following companies: Alfa Laval, Kockum Sonics AB, Höganäs Keramik, Skanska, Assa Abloy, Advakom, AnoxKaldnes, Lindab, Delovoj Peterburg, HL-Display and also a journalist from the Swedish Radio.Most of the problems named by the interviewees were similar, but some differences were also found. The differences were primarily found in the ranking of importance between the different problems.
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.
