ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.

The aim of this bachelor thesis was to examine attitudes among social workers, particularly their attitudes toward their clients? poverty and towards economic counseling as a method. A further aim was to study the relationship between attitudes towards poverty and economic counseling. Primary data used for the study was assembled among social workers (n = 111) with the use of an electronic questionnaire that was sent out to social welfare offices in 34 city districts in Stockholm,Gothenburg and Malmö. The findings showed that a majority of the social workers had a structural understanding of poverty and a positive attitude towards economic counseling.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Purpose/Aim: The purpose of this essay is to see how the media, through the newspaper, "Vi föräldrar?, produces family and parental roles, and to investigate how the image changed over time.Material/Method: The material consists of a number of selected texts from the years 1968, 1988 and 2008. The method used is a discourse analysis based on the three level model by Norman Fairclough. The three levels are the text, the discourse practise and the sociocultural practise. In this study two of the levels, text and sociocultural practise, are used in analysing the texts.Main results: Family and parenting in the texts from 1968 can be linked to the structural functionalist theory in which the core family is central and women and men are assigned to specific roles.

Sweden?s District councils and Country councils are in itself to a large extent responsible for the state financed welfare. Because of this, Sweden has a contribution- and adjustment system. The reason for this system is to create equal chance, for all District councils and Country councils, to be able to give the citizens service independently of their income and non-influential structural differences. The adjustment is built upon the so-called standard cost method, which contains four different parts.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.

This bachelor thesis aims to analyse the effects of changes in management control systems following acquisitions, and deduce whether or not these effects are in line with the acquiring firm's objectives of the acquisition. Through a case study of technician consultant firm Energo, acquired in 2010 by ÅF, the study assumes the perspective of the acquired firm. Data has been collected through in-depth interviews at Energo and ÅF and complemented by internal documents to enrich and validate specific facts and statements. Data was then arranged and analysed through Otley and Fierriera's (2009) framework Performance Management Systems to understand how management control systems were constituted before the acquisition, what changes were made following the acquisition, how this process was accomplished and how it was experienced, in order to come to conclusions about the effects of these changes. The study concludes that the changes in Energo's management control system following the integration with ÅF, had significant effects on the outcome of the acquisition, primarily as it led to a high rate of Energo's employees resigning.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage.

Most studies on parenthood and learning difficulties focus on mother and child, and very little is know about fathers with learning difficulties. Moreover, people with learning difficulties are rarely asked to tell their own narratives. The aim of the current study is to identify the role of the father in families where one or both of the parents have learning difficulties. Laws and regulations concerning the rights of people with learning difficulties in Sweden are accounted for and the he social support system for all parents in Sweden are described .The empirical study is a qualitative phenomenological interview study, inspired by narrative traditions, and describes how fathers with learning difficulties experience these support systems. The main data are two life stories of fathers with learning difficulties and one observation in a family.The findings suggest that although Sweden has a highly regarded disability policy and social support system, and even though fathers with learning difficulties are assured equal rights as members of the society and as parents by the Act of Human Rights, they are not treated equal but still faces structural inequalities.
