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.

Passivhuset i det långa loppet : - hur påverkar brukarens kunskap energiförbrukningen?

The scope of this investigation is to decide how and to what extent the energy consumption of apassive house is affected by the users? knowledge and habits. To achieve this a literary study hasbeen made and as a complement the planning of a passive house was completed.The result of a primary study of the rules and regulations that effect passive houses in Swedenshows that the user?s influence on passive houses is a completely unregulated area. Even thoughthere is no regulation, a need for some general knowledge of the passive house concept has beenexpressed.To further investigate how the users? knowledge and habits affect the energy consumption and ifthere is a difference between different households? energy consumption , three main factors havebeen identified.

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.

Skolkuratorers anmälningsskyldighet om barn som far illa

Sweden has an obligation to report child abuse suspicions to Social Services. According to Socialtjänstlagen (swedish constitution) 1 § Chapter 14, all employees in agencies affecting children, such as schools, have a responsibility to report their suspicions. Research shows that many abuses are not reported. The consequence of this is that Social Services does not hear about all cases of abused and harmed children. One profession where reporting is mandated is school counselors.

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.

Hur svårt kan det va´? : Från formuleringsnivå via transformeringsnivå till realiseringsnivå i ämnet Dansgestaltning på gymnasiet

This report is a hermeneutic analytical study of a practical pedagogical situation. For three occasions I observed my own practice as a dance teacher and how a moment, choreographic approach in the governing documents for upper secondary school GY11 was executed in a group of dance students. The part is formulated in the course objectives for the courses on the arts program under the topic Dansgestaltning with focus on choreographic approach. The study is based on a socio-cultural thinking but also takes into account the prevailing gender theories and focuses on how the process of formulation level, through the transformation level is portrayed in the realization level of the dance regarding choreographic approach. The study illustrates educational research from both a dance perspective and a school development perspective.

PLASTHANTERINGEN I SVERIGE En kvalitativ studie om storstadskommunernas plasthantering utifr?n EU:s Plastdirektiv (EU) 2019/904

The aim of this essay is to examine the handling of plastic waste on a local level in the three municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of guidance within the theory of Multi-level Governance. By applying the EU directive 2019/904, about disposable plastic, and examining the global plastic problem, the efforts to promote sustainable use, and recycling of plastic, is analyzed. The method involves a qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes the base of the study.

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.

I skolreformernas kölvatten : Statligt kontrollbehov och synen på skolan som agent

This thesis examines the effects of the Swedish school reforms that took place in the early 1990?s. Theories such as Principal-Agent, Stewardship and Lipsky?s street-level bureaucracy are discussed as well as New Public Management (NPM). These reforms were heavily influenced by NPM, causing an increased level of street-level bureaucracy, and according to Principal-Agent theory some outcomes could have been predicted.
