Safe retrieval of nutrients to improve food security
Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites.
The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.
Nedskrivningsprövning av goodwill : Tillvägagångssätt och problematik
Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.
Funktionell validering av mutation i PUS-1 i en patient med mitokondriell sjukdom
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 demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.
Varför granskar ni mig? : En kvalitativ studie om användningen av Facebook i rekryteringprocessen.
This study focuses on the motives that recruiters can or may have within companies, organizations and authorities of using Facebook as a complement in the investigation of potential work-candidates. The study also explores the consequences that could occur regarding the boundaries of private and public spheres when recruiters are researching Facebook-pages of potential work-candidates.The results were collected by qualitative interviews with eight different recruiters from a wide range of businesses in Kalmar.By applying a framework of already identified uses and gratifications, we discovered six different motives of why recuriters would use Facebook as a complement while recruiting work-candidates. The motives are; security, guidance and advice, convenience utility, surveillance, curiosity and economic motives. We also discovered that the following consequences of researching Facebook-pages of potential workcandidates are that candidates are restricted in the possibilities of acting private on their Facebook-pages and that candidates have zero control of their published materials since recruiters sets the limits of what can be thought of as private and as public..
Metallersättning inom byggbranschen
In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

Viktstudie av Analysinstrument : Konceptförslag för minskning av vikt
This thesis report describes the development of concepts regarding how weight can be reduced to the analytical instrument Biacore 4000. This thesis has resulted in five different concept proposals, all of which is solutions to reduce the instrument's weight.The thesis started with a pre-study where the instrument's structure and function were studied using both Solid Works, the opportunity to study the instrument in real life were also possible done. During this phase, a weight study was conducted as well, in which the instrument's weight distribution was studied and mapped.Following the initial phase, the work proceeded by developing concrete concepts to reduce the weight of the instrument where focus mainly was on the two cabinets. In addition, another two concepts were revealed, both with a more general approach.At the final phase of the thesis, the concepts were compiled and evaluated among themselves and the initial instrument.The thesis resulted in a study of the instrument's structure and weight distribution, with suggestions on how weight may be reduced for the instrument.The result factors such as materials, and manufacturing were aspects that were taken into consideration.At the final section of the report, suggestions for further work in which different aspects are discussed can be found..
FEM i praktiken : En studie i FEM-Designs användningsområden inom konstruktionsprojektering
This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.
10 kamp i fjärrvärme : Hur ett befintligt fjärrvärmesystem kan bli mer effektivt
Fjärrvärmen utgör idag ungefär 12 % (48 TWh) av Sveriges totala energianvändning. Starka argument att använda fjärrvärme för att tillgodose bostäders och lokalers värmebehov är möjligheten att använda olika bränslen av skiftande pris och kvalitet, den goda verkningsgraden en centraliserad värmeanläggning erhåller samt fördelen med att kombinera produktionen av el och värme.Halmstad energi och miljö (HEM), förser Halmstad och närområdet med fjärrvärme och total mängd producerad energi uppgick 2009 till 596 GWh. Avfall och biobränsle utgör den största produktionsandelen men även industriell spillvärme samt mindre mängder olja och naturgas används för att framställa värme.Konkurrenssituationen för fjärrvärme är på många orter i det närmsta monopolistisk där en stor aktör äger hela marknaden. Det är viktigt att förbättra fjärrvärmesystemet för att i framtiden behålla dess konkurrenskraft. Följande rapport utreder och beskriver åtgärder för att göra ett redan befintligt fjärrvärmesystem mer effektivt.Utifrån möten med personal på HEM har tio punkter presenterats, vilka utvärderar olika delmoment i Halmstads fjärrvärmesystem.
Läxhjälpen: tidsstjälare eller en resurs för elever att nå målen? : elevers, lärares och rektors uppfattning av läxhjälpen på en gymnasieskola i Stockholm
For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

Maktbalansen mellan mannen och kvinnan i Domarboken 19
The thesis of this essay is how literary texts are selected in the teaching of Swedish in upper secondary school, and how teachers reflect upon gender in these selections. To answer the thesis question three methods have been used. Firstly interviews were held with five teachers of Swedish, which have been the primary source for the essay. In addition to the interviews, I have examined two literary anthologies used as teaching aid in the teaching of Swedish and lastly I analyzed the literature and authors that the teachers explicitly express that they use in their tutoring. The secondary sources of this thesis contain research on selections of fictional texts, literary canon and students? re-production of gender.
