Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Hälsoinspiratörer : En kvalitativ studie om hur hälsoinspiratörer inom kommunal verksamhet upplever stöd och motivation i det hälsofrämjande arbetet

The workplace is perhaps the most developed arena for prevention of diseases and injuries among employees. In addition, according to the Swedish Work Environment Act, the employer is responsible to address physical and psychosocial risk factors. Moreover, many employers use health promotion, primarily related to individuals and their ambition to maintain or improve health, for example through dietary means and exercise. The aim of this study is to investigate health inspirers in municipal activities and their perceived support and motivation in work related to health promotion at the workplace. A qualitative method was chosen where six health inspirers within Ludvika kommun were interviewed.

Halvledare för höga strömmar i fordon

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

Oro för barn som far illa : förskolechefers tillämpning av anmälningsskyldigheten

The purpose of this study was to investigate how directors of preschool apply the mandatory reporting and what information they say is important in the decision to report child maltreat-ment. The study was built on five semi-structure interviews with five directors of preschool working in Greater Stockholm. The perspective of this paper is sociology of law theory. This means to study how out of law information makes sense when director of preschool applies the mandatory reporting. The result was analysed with three different analytic tools: action plan, consulting social services and the considerations of the directors of preschool them-selves.

Den fysiska planeringens påverkan på människans rekreationsmiljöer : tillämpning av de åtta parkkaraktärerna inom balanseringsprincipen

The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.

Staden - fara eller frihet för kvinnor?

This report studies how the divergence between men and women is manifested in the physical space and how the representation of room recreates this divergence. Spaces are coded and women have traditionally been associated with private space and men with public space, leading to that the home is encoded as female space and public squares as male space. Thereby women lack a natural place in public space. The National Board of Housing, Building and Planning (Boverket) wants to change this situation by enforcing safety-creating measures based on gender equality theories.I have studied what potential risks the project initiated by Boverket as well as discuss the potential problems with representation. Can representation be used without freezing the space? I also search for methods for working with a gender perspective without reproducing gender stereotypes and roles and avoiding encoding the private as female and public as male? Also I use a public seminar with urban planners, artists and architects to retrieve how we work with these issues today.I conclude that city planning needs to incorporate new strategies of thought that does not divide space, e.g.

Nedfästning av oljemåleri på puts.En fallstudie från salongen på Mostorps slott i Halland

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

Kommunala kulturmiljöprogram : strategiska planeringsunderlag för landskapsanalys, kulturhistorisk värdering och utveckling av kulturmiljöer

In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.

Studie och riskanalys av sulfidleror i Uppsala stad

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

Dogs' behavioural responses to repeated positive events

Assessing the emotional state in animals is important in order to establish the quality of their welfare, therefore it is important to investigate under what circumstances animals experience these emotions and to find indicators of their existence. The aim of this thesis was to detect possible behavioural indicators for positive emotions in dogs. These behavioural indicators could be helpful to increase both dogs? and humans? overall well-being in today?s society since they could help e.g. dog owners and caretakers to interpret behaviours displayed by dogs and their intentions so they can respond accordingly.The subjects used were 9 research beagles and each dog participated in three different treatments, assumed to be experienced as positive situations, where communicative interaction was initiated with the dog by engaging in 1) physical contact (P), 2) verbal contact (V) or 3) both physical and verbal contact simultaneously (PV).
