Plan för multifunktionella buffertzoner längs Vramsån påMalörten AB : s jordbruksfastigheter
To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.
Utvärdering av två hullbedömningssystem för katt av en djursjukskötarstudent och djurägare
Obesity is a growing global health problem among both humans and cats with the risk of several medical conditions as a result. This can be detected and prevented by body condition assessment methods in order to visualize and detect possible or potential weight problems in cats.To achieve the best results, owner and cat should be introduced to this as soon as possible in their contact with veterinary care.Purina Body Condition System and Walthams Feline Body Mass Index are both morphometric assessment methods that are quick, relatively cheap and simple to perform. 20 cats with owners and a veterinary nurse student participated in a study to compare pet owners and a veterinary nurse student's assessment of the Purina Body Condition System and WALTHAM's Feline Body Mass Index. The body condition assessment methods were compared with each other, and it was investigated which method was preferred, the body condition distribution among the studied cats and if long-haired cats' body condition was more often misjudged. Results of the study showed a significant difference between pet owners and the veterinary nurse student's assessment of Purina BCS with a difference in median of 1.
Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie
More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.
AKTIV FÖRVALTNING : En undersökning av fonders riskjusterade avkastning, persistens i fonders prestationer och sambandet mellan graden av aktiv förvaltning och fondernas överavkastning
I dagens premiepensionssystem finns det två typer av aktiefonder, dels indexfonder och dels aktivt förvaltade fonder. Denna studie undersöker om aktivt förvaltade Sverigefonder och tillväxtmarknadsfonder lyckas uppnå en högre riskjusterad avkastning än valt jämförelseindex, om de aktivt förvaltade fonderna uppvisar persistens i sina prestationer och om det föreligger ett samband mellan graden av aktiv förvaltning och fondernas riskjusterade avkastning. Studien undersöker 38 Sverigefonder och 43 tillväxtmarknadsfonder under åren 2007-2013. Som mått på den riskjusterade avkastningen används i denna studie Jensens alpha, Sharpe-kvot och Treynor-kvot. För att undersöka persistensen har två olika varianter av contingency tables använts för att mäta persistensen både på kort och lång sikt.
Radonfritt boende : Stegen till att eliminera radongas med rätt Grundläggningsmetod
People who live in northern part of the world spend much more time indoors than those who live in warmer countries. In addition that home should be safe, it should also protect one against heat, cold, sunlight and pollution. The indoor environment is affected by installations, material and how the building is formed. Those anomalies that are visible, felt or smelled can be noticed and be rectified. But it?s much more difficult if these abilities are missing.
Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro
The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.
Utvärderingsmetod Säkerhetskultur : Ett första steg i en valideringsprocess
Företag investerar idag väldigt mycket pengar på att säkra sina fysiska och logiska tillgångar med hjälp av tekniska skyddsmekanismer. Dock är all säkerhet på något sätt beroende av den enskilde individens omdöme och kunskap. Hur går det avgöra att organisationen kan lita på individens omdöme och kunskap? Hur går det avgöra om en organisation har en god kultur kring säkerhet? Genom att utvärdera säkerhetskulturen kan organisationer få ett utökat underlag i riskhanteringsarbetet samt en bättre förmåga att hantera det som hotar verksamhetens tillgångar. Den forskning som finns idag på området säkerhetskultur är både oense kring vad som utgör god säkerhetskultur men framför allt hur kulturen ska utvärderas.
Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik
This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.
Leder Aktiv Avkastning till Aktiv Risk? : Påverkas svenska aktiefonders risktagande av historisk avkastning
Den svenska fondmarkanden har haft en enorm utveckling de senaste tio åren med en kraftigt ökad fondförmögenhet och en börs med både signifikanta upp- och nedgångar. Den höga volatiliteten på marknaden föranleder att både fonderna och deras förvaltare bör analyseras noga, bland annat för att analysera hur fonderna hanterar aktiv avkastning. Ett område som är specifikt intressant att studera i relation till avkastning är hur förvaltare ändrar sin risk som en direkt effekt av förvaltarens prestation. Sambandet antas vara kopplat till hur förvaltare blir kompenserade samt hur fondinvesterare agerar i olika avkastningssituationer. Tidigare studier från den amerikanska marknaden visar på att när en fond presterar relativt sätt ?dåligt? och avviker negativt från sitt jämförelseindex riskerar förvaltaren inte något personligen.
Konstruktion av instrument för dragprov på nervceller
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

Hedgefonder : En empirisk studie om olika hedgefondstrategier och deras påverkan på avkastning
Investment in hedge funds is a relatively new phenomenon for investors compared with other forms of savings. In recent years, the interest has increased among investors in investing their money in hedge funds, given the protection against declines in the market they are aiming for. Their main purpose is to generate a high return at a low risk regardless of market trends. This they can achieve by having fewer restrictions that offer more flexible investment strategies and freer investment opportunities.The purpose of this paper is to identify how the selected hedge fund strategies have performed during the recent economic downturn. We also want to clarify the claim that hedge funds exhibit a positive absolute return regardless of what the market is performing.In order to answer the purpose of the essay and its problems, we have used a quantitative method with a deductive approach in the processing of data.
Metaller i dagvatten - Effekter i recipient : En analys av koppar, kdamium och zink i dagvatten från en parkering i Halmstad, Sverige
When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.
Värdehöjande tjänster att ta hänsyn till vid nyetableringar av träningsanläggningar : En kvantitativ studie baserad på beslutsprocessmodellen
Idag äger drygt 7 miljoner svenskar någon typ av värdepapper. Dessa handlas av två typer av investerare, den aktiva och den passiva. Den aktiva investeraren köper och säljer sina värdepapper mer frekvent för att dra nytta av dess upp och nedgångar, jämfört med den passiva investeraren som köper värdepappret på lång sikt.En aktiv investerare analyserar ständigt marknaden och dess utveckling, försöker utläsa historiska mönster för att förutspå hur framtiden kommer att utveckla sig. Att studera historiskt kursdata för att förutspå framtida mönster kallas teknisk analys . Två vanligt förekommande analysmetoder inom teknisk analys är glidande medelvärde och Relative Strength Index.
Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac
Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.
