Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning
AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.
Vad bör sägas? - en begreppsanalys av förändringar i synen på yttrandefrihet
This essay intends to investigate the view on freedom of speech in Sweden. The expanding of the hate crime law rises the question if there is a current changing view on freedom of speech. By comparing motions concerning an expanding of the hate crime law from different periods, I am able to conclude if and how the view on the term freedom of speech has taken place. This is done in a descriptive analysis of terms, where the different values and arguments for a change is compared. The material is taken from the period 1991-1993 and 2000-2001.
Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety
of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle
perspective is applied.
Att leva som regnbågsfamilj : En kvalitativ studie om homosexuella föräldrars erfarenheter av att leva i ett heteronormativt samhälle
The thesis aims to study how rainbows families are being treated by the authorities and the surroundings. It focuses on how homosexual parents are met in society. Although, homosexuals have the legal right to have a family and enter into marriage, the social norms are still far behind and rainbows families are seen as ?the others? and abnormal. Earlier researches have been studding how the authorities still assumes that every family are living in a heterosexual family constellation. By this assumption they exclude families who are not living in a heterosexual family.

Grundläggning med cellglas : En studie av byggtid och lönsamhet
This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.
Miljöbedömning av olika behandlingsmetoder för organiskt hushållsavfall, slakteriavfall och flytgödsel
Organic material used for biogas production can also undergo other treatments. The
emissions and impact from the different treatments are evaluated in this
environmental assessment, with a focus on energy and climate. The materials
included in the study are organic household waste, slaughterhouse waste and liquid
manure. Other than biogas production, the possible treatments for organic household
waste and slaughterhouse waste are incineration and composting, and for liquid
manure storing and spreading. The analysis is based on data and information from
current and relevant literature, and relates to the conditions in the Swedish energy
system.
Power supply monitoring for wireless sensor platforms
Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.
En ny förskola i Lerum
ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

Varför kommer inte fler kvinnor upp i hierarkin och gör karriär inom revision? Är det en tidsfråga eller finns det ett glastak?
The number of women in Swedish firms of accountant is not lower then the number of men, but when we compared the number of chartered auditors, the number of women are low compared to men. This is connected to the public debate that is mainly emphasising that there are no differences between men and women and therefore the sexes should be treated equal. The method used is a qualitative study and the primary data was collected through interviews. The respondents consist of members, women as well as men, from eighteen auditors in Malmö and Kristianstad. The result shows that both male and female characters are needed in the work on the firm of accountants.
Påverkar anställningsskyddet ungdomars situation på arbetsmarknaden i EU?
The main focus of this essay is to analyze whether strict employment protection legislation has a negative effect on the labour market possibilities for youth in the EU or not. To empirically examine the labour market possibilities for youth, data for unemployment rates and incidence of temporary jobs are used. By doing simple correlations between the different labour market characteristics and OECD?s employment protection legislation index the effect of the latter is tested. The result is that a tendency for youth unemployment and frequency of youth with temporary employment to be higher when employment protection legislation is strict can be seen.
Utvärdering av vattenrening och identifiering avförluster m a p energi vid Bravikens pappersmaskin 53
This Master degree project has been performed at the Braviken paper mill on papermachine 53 (PM53) which produces newsprint paper. The current economic situationhas contributed to declining demand for newsprint, which means it is extra important tobe competitive by high energy efficiency. Particularly as energy prices are expected torise when the economic growth returns.One way to increase energy efficiency is by reducing the water use in paper and pulpmills and consequently save energy through reduced heating of water. The thesis's maintask is to evaluate whether a water purification plant (microflotation plant) forpurification of process water in PM 53 is profitable. The microflotation plant enablesreuse of warm process water instead of losing the energy to receiving waters.
