The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

This study is qualitative and aims to describe and analyze how senior citizens with alcohol- related problems are recognized by social workers within local care for the elderly. The empirical material consists of eleven semi-structured interviews which was completed with the help of social workers within local elderly care. The findings of the study shows that the processing of the senior citizens alcohol related problem can be explained as an identified ?awareness process.? Further, the findings of the study shows that awareness is often made by others than the social workers themselves. The study has also showed that known versus unknown information about present alcohol-related problems, tends to be crucial for when and how awareness is made in the ?awareness process?. .

The acts of promoting local business and implementing efforts to appear as an attractive location for potential business are rather new activities among Swedish municipalities. The knowledge about how these activities are organised and what strategies are perused are fairly limited. In addition the structures concerning cooperation between municipalities for economic policies contain incentives both for and against cooperation. This creates a complicated situation. Using prior research mainly done by Markus Gossas, Lennart J Lundqvist and an analytical model designed by Jon Pierre, which in this essay is completed with the works of Roger Henning, these issues are addressed.

Municipalities with a higher amount of female representatives has been shown to be more gender equal. Earlier reasearch has also shown that female politicians are more likely than male politicans to represent immigrants and refugees interests. However, the effect of female representation has not been tested on other subordinated groups than women. Swedish municipalities have full autonomy regarding refugee reception and local politicians are responsible for the decision on the amount of refugees that the municipality accept. The variations of female and male politicians in the local assemblies are expected to have different outcomes on the refugee reception, according to females social backgrounds and experiences.

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews.          The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.

Based on 30 years of work experience in TV and film production, I have made a phenomenological analysis of my perception of meaning in work - how it arises and how it is undermined. The story starts in my experience of early professional film making in the 1980's and describes how a change to work in TV production required the development of a new professional identity. The text also illustrates how as a female director I have managed my role in a male dominated and structured work environment. Being defined as an exception from the male norm has pushed me towards femininist reflection and the need to redefine my own work role - the generally accepted view having felt uncomfortable. An analysis of structural change in TV and film production shows how market pressures and ways of thought have increasingly invaded cultural endeavour. Professional spheres of influence are weakened, while developments in the media are characterised by a commercialism which encroaches more and more upon artistic, spiritual and moral values. This attitude, where quality is in retreat, has transformedprogramme makers from creative originators into becoming suppliers of raw material in a factory- like process geared to produce great volume at low cost.The aim of this essay is to show how changes in society and in TV and film making have affected my perception of my work.

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

This is an empiric, qualitative, case study of cooperation between two public organizations in Ystad, Sweden (Försäkringskassan and Ystad kommun). The aim of the study is to illuminate why they cooperate and what happen with the idea to cooperate and the organizations when they do. The theoretical tools used are influenced by institutional theory. A translationmodel is used to illustrate what the local actors do with the idea when a decision is made to adopt it and how it affects the actors. The study suggests that the cooperation in Ystad called One Stop Shop is partly done because it's a popular way of organizing public organizations in Sweden and partly because försäkringskassan, aim to upgrade their organization identity.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

Hair care is a hygienic treatment and is supervised by the Local Environment and Public Health Committee in the municipality. According to the Swedish Environmental Code, hairdressers as all practitioners are required to take measurements to protect the environment and public health. In hygienic treatments hazards may arise from inadequate hygiene practice which spread infection. Hazards may also arise from the use of hair care products such as permanent wave solutions, bleaches and hair dyes. Some hair dye components are known to cause contact allergy, mostly in hair dressers who are exposed professionally but also in some cases in consumers.

The purpose of this thesis is to investigate how a local community, and those who dwell within its borders, are affected when a large scale windmill park is planned in its immediate vicinity. I have used a qualitative approach and conducted semi structured interviews to gather empirical data. The study took place in a small Swedish village named Svartnäs, situated in the region Dalarna.I have used the concept of community as a symbolic construction (Cohen 1984), that together with the theory of structuration (Giddens 1984) and the notion of expert system (Giddens 1996) served as my main theoretical perspectives.Even though the windmill park is not built yet, its impact on the people and the local community of Svartnäs has been considerable. In the traces of the new windmill park new options and constraints, that will play an important role in the lives of the people who dwell in Svartnäs, are arising. The windmill project is enlarging old conflicts and is creating a divided village.

During the 17th century the production and distribution of printed works increased in Stockholm and Uppsala. However, all works that the publisher wanted to print, did not reach the reader. This thesis aimed to show when, where and how printed books and dissertations did not reach the reader. To achieve this aim, aspects of several well known models showing systems of book production and distribution were combined and adapted to suit Swedish conditions in the 17th century. This combined model focused on processes of selection and was presented and used as a theoretical approach.
