Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

Att placera eller inte placera... : En studie om socialsekreterares handlingsutrymme i ungdomsärenden

The present study deals with the scope of action available to a social worker when analyzing, assessing and proposing measures regarding young persons experiencing social problems. The interest in the subject area emanates from the fact that the number of youth placed in different forms of round the clock out-of-home care in Sweden increases, whereas research in the subject shows that such placement gives few positive results and sometimes even has negative consequences for their development.The study investigates how the preconditions of the social worker influence their scope of possible action, in particular as regards their place of work, the situation of the individual dealt with, and the profession itself being one based both on scientific evidence and knowledge gained by experience. Lipsky?s theory on ?street-level bureaucracy? and Hasenfelds theory on human servicing organizations form the theoretical framework of the present study. The empirical input comes from interviews with focus groups of active social workers.The analysis of the interviews shows that social workers generally feel that they have a broad scope of action as far as the regulatory framework and office management are concerned.

Bestämning av vattenytor med hjälp av Nätverks-RTK och totalstation : Inmätning av Karlbergsån i Grums kommun

This report is presenting an approach that can be used to measure water surfaces in difficult conditions caused by dense vegetation and lack of nearby known points. The objective was to make a contribution to necessary measures for adaptation against floods in Grums Municipality along the stream Karlbergsån, which may occur when persistent rain raises the level of the stream. Along the river there are low-lying areas prone to flooding. According to Grums Municipality, the stream may widen where the water level differences are large, to create a better flow path and to counteract flooding. Grums Municipality was also interested in survey stormwater discharges which may affect the water level in the stream.

Utvärdering av Windows 8-applikationer ur ett utvecklarperspektiv

With Microsoft's new operating system, Windows 8, a new type of applications were introduced, Windows Store Apps.

From these films we like to see how youths are described, what attributes they are given, in shape of attire and different symbolic items, such as language and body expressions. The essay emphasizes which values that dominates among the illustrated teenage groups and compares it to the values and expectations that we can derive from an adult society. Here we let the school?s main determining base documents, Lpo 94 and Lpf 94, represent the dominating values of the society.Our hypothesis is that media, and also these films, creates images that affects the societies comprehension of teenagers and also how teens see themselves.

Utveckling av mobilapplikation

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

Den ena boplatsvallen är den andra lik? : Miljöarkeologisk intra-site studie av boplatsvallar vid Lillsjön, Anundsjö sn., Ångermanland

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

EU och demokratiskt underskott ? en experimentell studie om svenskar och stakeholdermodellen

EU:s befogenheter har främst motiverats med hänvisning till att internationella samarbeten effektiviserar beslutsfattande och förbättrar beslut. Idag ifrågasätter allt fler inställningen och menar att den har lett fram till ett demokratiskt underskott. På grund av underskottet menar kritiker att EU:s legitimitet påverkas negativt. Legitimitet underlättar för en auktoritet att få sina beslut accepterade och det får folk att följa regler och lagar. Genom Scharpfs begrepp om inputlegitimitet, deltagandet i beslutsprocesser, och outputlegitimitet, den upplevda effektiviteten av beslut, har debatten nyanserats.Som en följd av utvecklingen tilldelas unionens outputlegitimitet allt mindre uppmärksamhet samtidigt som fler intresserar sig för legitimitetens inputsida.
