Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

Alternativ hylluppställning: en undersökning av hylluppställning och biblioteksmiljö på Västerviks stadsbibliotek.

The purpose of this Masters thesis has been to study the changes made in shelf arrangement and library environment in a Swedish public library. The aim was to examine the reasoning done by the library staff regarding classification, the Swedish classification system SAB and changes in library environment. The basis of our study were three questions: 1. Why has Västervik public library made changes in the shelf arrangement? 2.

Topografins inverkan på markvattenhalten i ett jordbruksdominerat avrinningsområde

Topography is an important parameter for catchment hydrology, since it is a driver for water flow. Moreover, topography serves as a basis for hydrological models, e.g. ?Top-model?, which is based on a topographical wetness index (TWI). Few studies of TWI have been conducted on agricultural catchment scale. Four fields were studied in a Swedish drained agricultural catchment in order to evaluate the influence of topography on soil wetness.

Inomhusmiljöproblem i fuktiga byggnader : En utredning av åtgärder vid fuktrelaterade inomhusmiljöproblem

Dampness in the indoor environment have been a major issue of discussion the last decades since more and more people complain about their indoor environment. In the present situation there are difficulties to find what causes people?s discomfort in a damp environment even though there is a strong connection between dampness and human health.The aim of the thesis was to contribute to the work done today to achieve a better indoor environment in damp buildings. The purpose of the work was to evaluate whether the measures issued for dampness in the indoor environment contributes to the improvement of health and environment for those who are living or working in that space. Through a literature review, interview and survey the following three questions were answered to achieve the aim and purpose:How are people affected by the indoor environment in damp buildings?Which are the measures issued to prevent dampness in the indoor environment?Do these interventions contribute to a better indoor environment?How people are affected by the indoor environment in damp buildings and how these problems are prevented were the foundation for the continued work with the survey.

The study concentrates on which significance the pre-school?s yard and the outdoor environment has and how it influence the young children regarding their development and learning. The study is carried out through observations of the children complimented by interviews of them. The results show that children?s outdoor environment is important for their development of mobility, language, social competence and learning about nature.

Äldreomsorgens psykosociala arbetsmiljö : en studie av undersköterskor och vårdbiträden som arbetar med äldre på särskilda boenden

The purpose of this study was to find out how caregivers experienced their psychosocial work environment at three municipal homes for old people. The Copenhagen Psychosocial Questionnaire (COPSOQ) was used in order to study different dimensions of the work environment, and questions about health, sickness presence and sick leave were included. The questionnaire was answered by 86 out of 112 participating caregivers (77%). The results showed that the caregivers experienced high demands at work. The degree of feedback and influence at work was low, but they reported that their work was highly meaningful and that they usually received social support at work.

Skiftarbetets potential i byggbranschen

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Arbetsmiljö inom äldreomsorgen : en studie om enhetschefens resonemang och förhållningssätt i arbetsmiljöfrågor

The occupational group who works in the care of older people in Sweden is an exposed group since the work is often defined as a strenuous profession, both physical and psychically, and this puts comparatively many workers on sick leave.

Empirics were gathered from semi-structured interviews with six care managers from the care of older people administration in municipality of Kalmar.

Hur miljövänlig är dagens optikerbutik, och hur miljövänlig kan den bli?

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

Den psykosociala arbetsmiljöns betydelse och påverkan på ohälsan

This paper is about the psychosocial work environment, and those factors that can be responsible for an employee?s sick leave. We have through our knowledge from working life, on several occasions experienced colleagues becoming ill, the cause being the psychosocial working environment. Private factors, for instance different kinds of life crisis like a divorce or uprooting, have contributed to the sick leave. The psychosocial working environment is complex.

Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
