Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Nyfikenhet i skolans värld : Vad elever i montessoriklass beskriver som lustfyllt lärande

Studien har genom intervjuer i fokusgrupper undersökt vad elever i montessoriklass erfar som lustfyllt i sin lärmiljö.  Elevernas svar har satts i relation till den forskning som finns kring motivation och framgångsfaktorer för lärande samt till montessoripedagogiken.De teorier som studien utgår ifrån är olika motivationsteorier, teorier relaterade till motivation samt montessoripedagogik. Även framgångsfaktorer för lärande beskrivs. Tillvägagångssättet i analysen av fokusgruppsintervjuerna har inspirerats av fenomenografisk metodansats. De två forskningsfrågor som studien ger svar på är vad elever på mellanstadiet och högstadiet, i de undersökta montessoriklasserna, framför som orsaker till att de känner nyfikenhet att lära sig mer i skolan, samt vilka av dessa faktorer som är kopplade till montessoripedagogikens principer, och om de går att överföra till all undervisning. Resultatet av studien visar att eleverna pekar ut läraren som viktig för huruvida de ska känna nyfikenhet och lust i lärandet.

Sällskapsdjurens betydelse för den äldre människans livskvalité och omvårdnad : Systematisk litteraturstudie

Syfte: Syftet med studien var att undersöka vilken betydelse sällskapsdjur har för den äldre människans livskvalité och omvårdnad. Metod: En systematisk litteraturstudie med femton studier med kvantitativ ansats. Datainsamlingen gjordes i databasen ELIN och PubMed och genom manuell sökning av tidsskrifter. Huvudresultat: På ett äldreboende visade en studie att kanariefågel ökade livskvalitén, den självupplevda psykiska statusen och känslan av autonomi. Sociala interaktioner ökade i samband med Animal Assisted Activity och gav andra diskussionsämnen än de egna sjukdomarna.

Scennärvaro

Den här uppsatsen är ett försök att ringa in och samla ihop tankar kring vad det är att vara närvarande på scen samt hur man kan lära ut det. Arbetet innehåller citat och referat från intervjuer med sju personer: En skådespelare, en koreograf, en jazzsaxofonist och improvisatör, två sångerskor och sångpedagoger, en sångerska och låtskrivare samt en klassisk altviolininst. Här finns också citat och referat ur relevant litteratur. Arbetet ska ses som en ingång till ämnet snarare än en djupdykning..

Motion som egenvård : en studie om personer med erfarenhet av självupplevd psykisk ohälsa och psykiatrisk vård

Backround: Many studies indicate that people with mental illness often suffer from physical illness. Many people with mental illness do not exercise even though they often have knowledge about the benefits of physical activity. Studies suggest that psychiatric patients have the desire to have an everyday life with more content. It is apparent in studies that healthcare professionals believe that it is the patients' own responsibility to keep themselves physically active.Aim: The primary objective with this study is to examine motivation and possible obstacles to exercise for persons with self-perceived mental illness and experience of psychiatric care. The secondary objective is to investigate how psychiatric care may be of importance to people with mental illness when it comes to exercise.Methods: Semi-structured interviews.

Analys av turbulensmodeller för CFD

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Förrotation till omrörare

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
