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..

Lifestyle change starts as a process in which patients can be helped by a nurse through conscious communication, educate and support increased physical exercise.AimThe aim of this study was to investigate the district nurse´s experiences of interacting with patients with hypertension about physical activity.MethodIndividual qualitative study. Ten nurses from health center were interviewed.
Att sätta segel i ett av världens största sportevenemang : En studie av begrepp, motiv och utvärdering av sponsring
Problem. Sponsorship has increased continuously during the 21st century, however, at the same time the public interest of traditional promotion has been diminishing. The meaning of sponsorship is a very diffuse and therefore the concept needs to be investigated. Due to the multitude of sponsorship and its impreciseness about its financial value, it is difficult to evaluate sponsorship for companies, especially when there is a difficulty in choosing a decent method for evaluation.Purpose. The purpose of this thesis is to investigate the concept of sponsorship, motives for sponsorship and evaluation of sponsorship according to the theory and give empirical examples of how these areas are being managed by companies.Method.
Information till mjölkföretaget : vilken information behövs och hur bör den utformas när gården ska ta investeringsbeslut?
The fast developments in information and data technology during the recent years have accentuated the need for the business manager to interpret and act on information from the surrounding environment. Today we know little about what information is really used in the unique decision-making. Further, little is known about how information should be designed to fit people with a more intuitive approach to interpreting information. This study is therefore about the difference between peoples approach to interpreting information and how information should be designed to fit those with a more intuitive approach to interpreting information. The application is made to dairy farms in Sweden.
The literature review describes the strategic leadership, the decision-making process and the intuitive and the analytic thinking.
Flen : Om stagnation i skuggan av Stockholm
This thesis aims at analyzing why the municipality of Flen, in the eastern part of Sweden, has experienced strong depopulation for the last forty years in spite of its relative vicinity to Stockholm. The study uses current theories on regional developement, population theory and theories on regional enlargment to help explain and to evaluate the different regional factors that affect the developement of Flen on the local level. The thesis is primarily focused on the subject of regional policy and strategies to meet regional depopulation. The study also gives a presentation of the strategies of major regional institutions as well as analyzing what impact regional policy have on local policy in the municipality of Flen.Interviews with local officials, politicians and other people representing the population of Flen were carried out to achieve a better understanding of the specific challenges that the municipality faces and of the measures that are taken to meet them. Regional policy in Sweden prioritises measures that promote regional enlargment to link the housing and labour markets together with the regional infrastructure.
Effektivisering av LCA med hjälp av BIM
This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will make the LCA more comprehensive, unlike e.g. aluminum cans. Recently there has been a development of a working procedure in the construction industry.
Energieffektivisering av luftningssteget på Käppalaverket, Lidingö
This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.
Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..
Dynamisk massbalansmodellering av fosfor i Östersjön
During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.
Svenska sojabönor - finns marknadsmöjligheter?
The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.
Det är osäkert vad det beror på : Multiprojektstyrning i forsknings- och utvecklingsenheter
BACKGROUND: Project based structures has become more and more common in the organizations of today. As the project based structures are given a more central role in the organizations the interdependencies between the projects are getting more attention. These structures need a new type of control to meet the unique challenges that arise. The researchthat has been done has been concentrated around the project form and the projects internal control, the area of multi-project management is therefore relatively unexplored. The few existing studies on the subject focus on projects in the construction industry why research inmore complex fields of business have been requested.PURPOSE: The purpose of this thesis is to explore and analyze how knowledge intense multi-project organizations manage their project activities, and to determine how different organizational characteristics affect the need for management control systems.METHODOLOGY: The empirical data has been collected through interviews with personnel in BT Products R&D, Gambro R&D and AstraZeneca Development.

The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.
En komparativ studie av vinstdelningssystem bland advokatbyråer
Law firms are defined as knowledge-intensive companies. Due to the dependency regarding the resource of knowledge among the firms employees and to the fact that they often are categorised as a type of professional service firm. The purpose of this study is to investigate the different types of profitsharingsystems as a form of reward with focus on the theoretical differences and effects of the True Partnershipmodel and the Stockholmmodel. In addition to these models we will look into the Human Resource processes of; recruiting, integration, retaining and development of employees. The main purpose of the study is to examine the theoretical level on how the profitsharingsystems effect different Human Resource processes and through the knowledge of these connections using this as an analogy when to analyse other law-firms and knowledge?intensive company?s.
Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation
Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.
