Hållbarhetsfrågor vid produktion av An old friend
Jag har under detta arbete undersökt hur företaget MAD ELF ART kan arbeta med miljö och sociala aspekter i produktionen. Min uppgift har varit att lokalisera en materialleverantör och producent som kan arbeta med detta på bästa sätt.Under arbetets gång har jag kontaktat flera materialleverantörer och producenter och undersökt hur de jobbar med dessa aspekter. Samtidigt har jag även fördjupat mig i hur man kan ta hänsyn till miljö och sociala aspekter i produktionen, för att undersöka hur vi bäst kan arbeta med det.Vad jag kommit fram till är att materialvalet är det viktigaste och det som skiljer en produkt från att vara en miljöbov och en fara för människor till miljövänlig. Därför har jag i bilagan presenterat en leverantör och producent av materialet 100% silke som är ekologiskt färgad och handvävd. Silke lämnar inget energi-fotavtryck och går att återvinna.
Konstruktion Signalgenerator
SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.
GRAVMONUMENTET I HÄLLSTAD: ETT VISUELLT SKÅDESPEL FRÅN 1100-TALET
The aim of this master thesis is to study the reliefs of a Romanesque tombstone from 1130 AD, with the intention to form a plausible understanding of their meaning. During the course of the investigation, my main focus will be on collecting materials of an iconographical and historiographical nature, as they appear in previous studies. I will also use performative analysis when examining the tombstone. Consequently this thesis can be seen as a survey of history and place; early Christian iconology as well as the experience of the viewer. As a result, the 900-year-old tombstone will not only be seen as a memorial in this text, but also as a performance of one man?s faith and as representing the core message of the early Christian church.The tombstone is a rarity in Swedish art history and well worth a closer examination.
Hur könsroller skapas och reproduceras i läromedel : En undersökning av bilder i läroböcker för matematik för de yngre åldrarna
The purpose with this essay was to see how the mathematic books showed sexual roles in pictures and if they confirm or deny the traditional sexual roles that school shall counteract according to the curriculum, Lgr11. The questions I focused on were this:How sexual roles are introduced on the pictures in the chosen mathematic books?What are the similarities and differences between the presentations of the gender in the chosen education materials?I used a semiotic method to analyze my pictures. The central parts of my theories were how we think that gender is created using characteristics and attribute. In my analyze I found out that the pictures in one of the book series showed more stereotypic sexual roles than the other book series did..
Vaktelproduktion för ägg och kött
The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.
Åtråvärda objekt : En gestaltning av troféns materialitet
This thesis revolves around my work Desirable Objects, an installation in glass and other materials, which deals with objectification based on female and animal trophies. The topics included are those that have been crucial to my working process; craft, post-colonial studies and European hierarchical dualism, where woman and nature are seen as connected, but inferior. My motivation has been to get a better understanding of underlying power structures, and put this knowledge in relation to my own work. This process has led me to make a full body casting of my own body as a method of self-exploitation, in an attempt to expose myself to a similar power perspective. By making the dualistic connection between woman and nature, I am commenting a phenomenon that in my view has resulted in a similar exploitation of both..

Konstruktion av Laborationskort med PIC-processorn
In this report you can get a complete instruction about how to build your own development system for the PIC-processor. This card will be used for laborations for the students at LITH-ITN. With this card you can send new assembler codes (new instructions) down to the microprocessor via the Serialport on your computer. Then the new instructions for the microprocessor will start to execute. We made a solder paste stencil at Campus Norrköping solder paste stencil laboratory.
Matematik och flerspråkighet : När invandrarelever lyckas
The aim of this paper is to investigate and analyze practices in multilingual classrooms of mathematics in a compulsory school in Sweden where immigrant students have been known to succeed. The school is situated in a suburban and segregated area outside a major city where pupils come from mainly limited socio-economic backgrounds. The rate of second language learners are 70% of all pupils in this school.By using ethnographic methods, mainly interviews and participant observation, data was collected in four mathematics classrooms which corresponded to consecutive ages of education. The data include field notes and observation of artifacts in the environment as well as interviews and informal conversations with teachers and school leadership. Information from the school website, the authority in charge of quality in Swedish schools (Skolverket) and the municipality were also used.The analysis is based on a socio-political viewpoint that power is relational and reflected within schools.
Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

The guidelines develop a trademark for identification and loyalty, and give advice on how new materials can be made consistent with the trademark..
Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment
Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the
water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea
(Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.
Kinetisk Keramik
Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Att uppleva naturen med alla sina sinnen : Hur undersöker och upplever förskolebarnen naturen?
AbstractThis project discusses various aspects of children's way to explore nature with their senses. Therefore I conducted a study in two preschools, one nature-oriented and another preschool. This study was carriedout usien the three metods, interviews, observations and surveys. Interview four children from each preschool, observations of each group outdoors during four different occasions and question forms to teachers. The result of the study showed that both teachers and children have a great interest in being outdoors in nature, but it is not always possible to take out all children's groups. The reason is large groups and inadequate staff.
