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..

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..

Drömmen om Sverige: En studie av Exportrådets informationsfilmer "Världens möjligheter"

Within the fields of business as well as the academic, there is a growing interest for the role images play in an organized conception of the world. This paper acknowledges the relevance of such images and ideas, and its purpose is to examine the fixed ideas and conceptions of the world as they appear in a Swedish organizational context. The Swedish Trade Council is a hybrid organization between the state and private sector with an outspoken purpose of defining an image of the outside world for small and medium size enterprises in Sweden. The underlying question in focus for this study is: What central conceptions of the world appear in the Swedish Trade Council?s information films ?Världens möjligheter?? Within organizational studies, a postcolonial theory has to a large extent been overlooked.

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.

Finns det några skillnader mellan Socialdemokraterna och Moderaterna? : en studie om kommunalt självstyre på lokal och nationell nivå

The Social Democratic Party and the Moderate Party are two parties with different ideological background. The parties have different opinions in issues of public and private matters. The Social Democratic Party profiles it self, through the local and national party programs, as a party for solidarity and security. The Moderate Party, on the other hand, profiles it self through their programmes as a party with a possibility for the individual to shape his or her own life. Through a survey on members in the local government, and two key persons at national level, the view of municipal self-government has appeared.

Konst och kultur : Möjligheter och hinder att använda konst och kultur som rehabiliterande metod inom primärvården

Background:There are future challenges for public health and health care in meeting the needs of a growing and ageing population. Today there are evidence of how arts can contribute to health development and of the connections between arts, health, treating and rehabilitating measures. To be able to meet the future challenges there is a need for new methods, perspectives and views about how to stay healthy, enjoy our existence and for wellbeing. Health care has an important role in rehabilitation through the broad contact with the population. The background of the essay is the pilot project Arts on Prescription that was carried out in order to try a new way of rehabilitation with arts as a factor.

Det etiska klimatets påverkan på revisorers val av förhållningssätt till sina klienter

Aim: Auditors objectivity is an obvious part of auditing, but there is doubts and hesitation in society today because of the corporate scandals that have occurred in recent years. Several researchers suggest that auditors actions and behaviors is connected to the ethical climate within the organization. A relationship that also affects auditors objectivity and independence. This thesis aims to investigate how the ethical climate influence auditors choice of relationship to their clients, by choosing a relational and close relationship or a transactional and distanced relationship. And if the client approach have an effect on the auditors objectivity.Method: A survey was conducted among 232 certified accountants in Sweden.

Bibliotekariens nya arbetsmarknad

The purpose of this thesis is to examine why graduates in librarian- and information science are employed by private companies. An initial explanation could be the influence of information technology and its impact on the librarian. A second factor relates to how employers regard the librarian outside the confines of the traditional labour market. The study is primarily based upon qualitative interviews with representatives of Swedish companies who have employed librarians since 1993, the year that the education achieved third level academic recognition. Theoretically we relied upon Manuel Castells discussion on the rise of the information society and its influence on companies and the labour market.

Vägen till ett självständigt liv? : en studie om Rekryteringsgruppens betydelse för ryggmärgsskadades rehabilitering

Aim?Rekryteringsgruppen? (RG) is an organisation that through co-operating with the National Health service aims at optimizing the ability for physically disabled persons to rehabilitate. RG is a non-profit organisation ?using physical and mental exercise for disabled people, mainly neurologically disabled persons.? One of the goals that RG wants to achieve is ?that the target group will be able to live such an active and independent life as possible?. As no previous studies have been done in order to review the adaptation of RG:s work and its effects on the disabled, the purpose of this paper is to examine spinal cord injured individuals perception of independence concerning situation of life, ability to function and physical activity.MethodData have been collected by using three questionnaires.

Utvecklingen av mekatronikämnet på KTH : ? anställningsbarhet, forskning och innovation

This thesis examines history of the subject of mechatronics and innovation. The main reason tostudy mechatronics from a historical point of view is that it has never been done to a greater extent before. An overview is justified because various definitions have been used over the decades, but nowadays the subject has become more established. Focus in this thesis is mainly on development of the subject of mechatronics at Royal Institute of Technology in Stockholm. Innovation is the other aspect of this thesis.

"In i sagans land" : Aktionsforskning i bibliotekspraktiken med syfte att utveckla sagostunden

The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.

Attityder till implementering av precisionsodlingsteknik :

Different techniques for precision agriculture have been available during the last decade. Some of them are more widely used than others. The main purpose of this thesis was to investigate the different attitudes to precision agriculture that exists among farmers and advisors in Sweden. Eight advisors and sixteen farmers were asked for their opinion of a number of specific techniques for precision agriculture, such as yield-mapping, precision liming, the Yara Nitrogen Sensor and site-specific fertilization with phosphorous and potassium. They were also asked to describe the way in which the counselling in Swedish agriculture is used and also about it's importance for the adaptation of new techniques. The high costs are mentioned to be one of the most important reasons why precision agriculture hasn't been more widely spread. Several farmers refer to their farms as too small to bear the costs that come with the techniques. The individual interest for technique among the potential users plays an important role.

Introduktionen av tapeter på den svenska landsbygden 1850-1890 : en studie av attityder vid kulturspridning med utgångspunkt i Nordiska museets frågelista om tapeter

The aim of this essay is to examine how people living in the Swedish countryside looked upon changes in the interiors through modernization in 1850-90. For the first time, there was an abundance of objects available in stores in the countryside that the majority of the population had money buy. Many novelties were introduced in the interior decoration of ordinary peoples´ homes. This study focuses on the introduction and use of wallpaper and is based on a questionnaire about wallpaper sent from the Nordiska museet, National museum of Culture history in Sweden, to people all over Sweden in 1948. 148 people responded to the questions about use and attitudes toward wallpaper during the second half of the 19th century.My theoretical perspective is cultural diffusion, the spread of cultural items, more specific the diffusion of innovations from larger to smaller places, often influenced by social elites, hierarchical diffusion, and between individuals, contagious diffusion.The analytical perspective used for the analysis is based on the concepts of basic and variable modernity, initiated by the historian Sven-Eric Liedman.

Trivsel i ett passivhus-en kvalitativ undersökning om de faktorer som påverkar trivseln i en bostad

Att tillägna sig sin bostad är en viktig aspekt för att kunna känna sig hemma i sin egen bostad. Arkitekten Ola Nylander presenterar i sin forskning sju egenskapsfält (material och detaljer, axialitet, omslutenhet/öppenhet, rörelse, rumsfigurer, ljus och rumsorganisation) som kan fungera som måttstockar för hur väl en lägenhet går att ta till sig. Uppsatsen utgår från de sju egenskapsfälten och undersöker, genom dem, hur de boende upplever trivseln i sin bostad. Alla bostäderna i undersökningen är placerade i ett passivhus på fastigheten Flaggskepparen 5 i Västra Hamnen Malmö. Syftet med uppsatsen är att undersöka vilka egenskapsfält som är viktiga för hur de boende upplever trivseln i ett nyproducerat passivt flerbostadshus. 9 stycken kvalitativa intervjuer har därför genomförts med de boende i fastigheten. Dessa intervjuer har varit mellan 20 och 60 minuter långa och genomförts på plats i respondenternas lägenheter (alla utom en).
