This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.

The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.

Swedish goats are mainly held for cheese production and therefore, both milk quality and composition are of great importance for dairymen. Today, only few data exists on milk composition from Swedish dairy goats and the casein content is still unknown. One way to reduce the work load for goat farmers and increase animal welfare can be to keep goats and kids together for longer periods. The aims of this study were to investigate how milk yield and composition were affected when kids suckled their dams during 8 weeks, and to measure the casein content on farm level by a mid-infrared spectroscopy method, previously calibrated for goat milk. Lactating goats were kept in two different MIX- systems where the dams are both suckled and milked.

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.

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

This study departs from Gállok, an area 40 kilometres northwest of the city Jokkmokk, in northern Sweden. This is a place to which local people and Saami reindeer herders have material interests and emotional bonds. The mining company JIMAB wants to prospect for extracting minerals from this area. In the summer of 2013 local people, Saamis and environmental activists gathered in Gállok in order to protest and make resistance against these plans. Activism was made, debate articles were written, demonstrations were organized and information about what was going on in Gállok was shared through social media.The aim of this study is to examine the cultural processes of the anti-mining movement, in particular the happenings in Gállok in summer 2013.

Brottsligheten i Sverige har ökat. Två av fem individer återfaller i brott efter frigivning. De individer som lever i utanförskap och kriminalitet är i en utsatt position. Flertalet av kriminalvårdens klienter har behov av insatser från olika verksamheter för att klara sig från återfall i kriminalitet. Syftet med studien är att få en djupare förståelse om vad före detta kriminella anser har varit betydelsefullt i deras process att lämna sin kriminella livsstil.

This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Detta är en kvalitativ studie vars syfte är att undersöka vad som karaktäriserar ungdomars sociala relationer. Mer precist är vi intresserade av att undersöka i) ungdomarnas relationer till familj, vänner och myndigheter ii) vilka emotioner som ungdomarna associerar med sitt drogmissbruk och/eller kriminalitet samt iii) vilken betydelse relationerna har haft för utvecklingen av drogmissbruk och/eller kriminalitet.Vi utförde intervjuer med fyra ungdomar inskrivna på ett behandlingshem för missbruksproblem. Ungdomarna har varit i behandling mellan en och sex månader. Frågorna ställdes utifrån en intervjuguide som bygger på uppsatsens syfte, tidigare forskning och teori.Vår tidigare forskning består av studier om sociala relationers inverkan på ungdomar med allvarlig social problematik såsom drogmissbruk och brottslighet. Teorierna handlar om sociala band, skam, skuld och stolthet samt Hirschis sociala kontrollteori.Resultatet av undersökningen visar att samtliga respondenter hade försvagade sociala band till sina föräldrar under uppväxten och fram tills de slutade missbruka, vilket troligen har påverkat deras utveckling av drogmissbruk och/eller kriminalitet.

Freedom of establishment statutes that restriction of citizens within the EU can not occur. A citizen should be free to establish themselves in a Member State and not be hindered if they choose to leave the State. "Citizens" also includes legal persons such as companies. Legislations in Member States which prevents the freedom of establishment shall be prohibited. When a company chooses to merge across borders and thus cease to be a Swedish company, the Swedish rules for exit taxation applies.

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

The purpose of the essay is to by means of a quantitative method investigate what the portrayal of GLBT-people looks like in a selection of Swedish and New Zealand newspapers. The essay focuses on aspects such as the gender ratio between GLBT-people who are mentioned and also those who are allowed to speak out in the newspapers. Also in what proportions the newspapers portrays the different fractions of the GLBT-term, what subjects are covered and what types of sources are used are areas of interest.The analysis is conducted through a quantitative research method where two Swedish newspapers (Aftonbladet and Dagens Nyheter) and two New Zealand newspapers (The Dominion Post and The New Zealand Herald) were selected. Three periods of 15 days were selected for each newspaper and electronic databases were used in order to try and collect all articles with relevance for this study.The theoretical background consists of Tiina Rosenberg?s theories about media?s role in the individuals? identity shaping, Nina Björk?s feminist theories connected to gender and power, and the patriarchal structure of society, and also Anders Sahlstrand?s accounts of journalism?s use of sources and their effect on the audience?s perception of the news presented.The main results from the analysis points towards preponderance in the occurrence of male homosexuality and male homosexuals.
