Optimering av ett mellanspänningsnät : Optimization of a medium voltage electricity grid

EU vill genom att använda energin effektivare sänka sina energikostnader och minska sitt beroende av externa leverantörer av olja och gas vilket leder till att miljön skyddas. Av den anledningen krävs att energieffektiviteten ökas från produktion till den slutgiltiga konsumtionen inom EU. Jämtkraft är miljöcertifierat enligt ISO 14001 och arbetar därför årligen mot uppsatta miljömål. Detta examensarbete har studerat ett av dessa mål, möjligheten att minska överföringsförluster i ett av Jämtkrafts mellanspänningsnät. Området som examensarbetet baseras på är fördelningsstation Nälden FS23.

Kan man minska bilåkandet i staden? : sett ur ett stadsplanerarperspektiv

The reason why this essay is written can be parted in two, whereas one would be the global trend of urbanization that occurs to this moment and forward, whereas the other would be the debate of how motorism has come to be an issue of sustainable management of our cities and our environment. In purpose to deliver a thorough understanding of how the car and its capacity has come to shape the society of today, and to emphasize the problems it´s brought, a historical survey has been made, followed by the report of problems to the society formed by the needs of the car, discussed in several environmental issues, such as jamming, noise and air pollution. This is followed by the discussion of potential solutions for how city planning could return to the focus of the human scale and perspective, in purpose to correspond with the issue of ways to decrease the car use in towns. In conclusion, the given solutions are discussed, where examples like shared space, investment in public transport, mobility management and the theory of the assembled city are included, with aid from literature, to finally conclude the essay with personal thoughts of how the planning of today, or the given solutions, really are the result of sustainability for city planning from a human perspective.

Vindkraft och rennäring

The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined. The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.

Biblioteket i Alexandria historien om ett bibliotek

Det digitala skolbiblioteket. En möjlighet för utveckling av såväl verksamhet som yrkesroll?

The aim of this paper is to study if implementation of a school library management system called FreeLib has created favourable conditions for the school librarians to cooperate with other professions and become a more forward working place. I have studied relevant literature about school libraries, organisation, digital libraries and documents that regulate school and library activities today as well in the past. In order to fulfil my purpose I have done a qualitative survey with six school librarians from Swedish primary schools with pupils at the age of 6 -16 years old. To identify strengths, weaknesses, threats and opportunities I found in the material I used a method called SWOT analysis. According to this study the use of the digital FreeLib system has developed a better teamwork between school librarians at different schools.

Hur organiserar forskare sitt material? : Personlig informationshantering i en vetenskaplig forskningsmiljö

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

Anaerob rening vid StoraEnso Skoghalls Bruk

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Odlingsstrategier på organogena jordar : en studie om beslutsfattande bland KRAV-anslutna lantbrukare

This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.
