Vindkraft eller kärnkraft - En jämförelse

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Molecular analysis of insecticide resistance in pollen beetle (Meligethes aeneus)

The escalating Usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

Om utformning av ett verksamhetssystem : En utvärdering av nuläge, tillgänglighet och erfarenheter

These days most companies conduct some form of work for the external environment, quality and safety. In connection with this work, some companies have chosen to get management systems certified by any applicable standard for one or more of the fields while other companies have chosen other ways that are not associated with certification.In light of the fact that the individual systems are becoming unmanageable an increasing number of these companies are faced with the decision whether to integrate and coordinate these different systems or not. In order to study the possibilities of a company?s system coordination an assessment of elements particularly interesting for the company was performed. The key elements and focuses in the evaluation were staff access to information, experiences from other companies and environmental work status for some of the organization's companies.

Detektor på skördare för utsortering av träd med metallskrot

Fortifikationsverket which is the landlord for the Swedish national defence has a great problem in their forestry due to the relatively large amount of metal objects in their timber. These metal objects cause different types of economical losses in the timber refinement chain. To enable out sorting of logs containing metal objects already in the harvesting phase, Fortifikationsverket is interested of the possibility to utilize some type of metal detector in a harvesting head for that purpose.The goal of this study was to, with help of a case study, enlighten the problem that metal objects in timber cause for Fortifikationsverket and their customers of timber and to investigate conditions of to mount and utilize some kind of metal detector in a harvesting head at present.The saw timber deliveries by Fortifikationsverket during the time period 2003-2005 was used as a reference volume for calculations of economical losses. In this case study was included two sawmills where timber from Fortifikationsverket were delivered to for further refinement. Factors investigated were the type of damage metal objects caused in these two sawmills and the economical signification of these damages.

Effektivisering av energianvändningen i en förskola

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Jämkning vid bodelning - en möjlighet för båda parter? : En analys av 12 kap 1 § äktenskapsbalken

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

Positiv särbehandling - diskriminering eller ett nödvändigt led i jämställdhetsarbetet?

To achieve the goals that the government has put in place for equal opportunities in the labour market, the Swedish law is divided into two separate regulatory frameworks. One is positive action to promote equal opportunities and the other is the prohibition of sexual discrimination. Since males, despite the measures taken so far, still have a great advantage on the labour market, the law concerning equal opportunities has an exception from the prohibition of sexual discrimination, whose purpose is to promote the progress of equal opportunities, also known as preferential treatment. The regulations concerning preferential treatment allow the employer to hire a less qualified person from an underrepresented gender in spite of the presence of higher qualified applicants of the overrepresented gender. The purpose of this paper is to investigate the meaning and the application of preferential treatment as well as to give an insight to the argumentation around its application.

Olikheter på arbetsplatsen. En studie om prioriteringar och marginaliseringar i svenska organisationers mångfaldsarbeten

Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.
