Research indicates that a more hands-on education in mathematics could improve how students relate to mathematics. Laboratory mathematics is a way of making mathematics more concrete.  How is the purpose of laboratory mathematics perceived? This thesis has its focus on the pupils? perceptions of the purpose of laboratory mathematics, but the intention of the teacher involved is also investigated. The main research questions asked were:What is the teacher's definition of laboratory mathematics?Which is the teacher's purpose in using laboratory education?How do the students perceive the purpose of the laboratory teaching of mathematics?To answer the questions, I conducted a series of qualitative interviews.

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.

Almost 10 years after the attack on World Trade Center Sept. 11 2001, Osama bin Laden was shot and killed on May 2 2011 in Pakistan. How was this event framed by the media with regards to the global war on terror? This study compares two different American newspapers ? the New York Times and the New York Daily News ? and how they framed the war on terrorism in the Middle East from May 2 to May 15 2011. By analyzing the framing in a perspective of the four functions of framing theory: define problems, diagnose causes, make moral judgments and suggest remedies, we found considerable differences in each papers frames.

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

The purpose of this study is to from a client point of view study the release process. The first issue is which positive and negative aspects on the release situations that are revealed trough the interviews. The second issue is which changes that are needed to improve the conditions for the release work to be crime preventive. The study has been performed by means of qualitative interviews with clients, and one person with a long professional experience of treatment of offenders. The results show that the release work has generally not been successful.

This study deals with the concept of ?integration?. Starting from the concept of reality as socially and linguistically constructed, it is an attempt to see how lingual constructions and perceptions affect the official structures of society and vice versa. The main purpose is to compare the different meanings integration has in a sociological context and in a political one. Further, the purpose is to see how the relationship between the sociological and political concepts affects the integrational work in the Swedish County Administrative Boards, and which consequences these effects might have.

Homeless adolescents are in Sweden rather invisible, as a group. There is no established definition or description of the problem, nor any uniform terms regarding it. The purpose of this study is to investigate how four different organizations, based on their basic principles, describe the group homeless adolescents. We discuss why the organizations reason as they do, and what it leads to. In order to do so we have performed qualitative interviews with representatives from each organization.

Bakgrund: Felaktiga arbetsställningar utgör ett dominerande arbetsmiljöproblem inom frisöryrket. Ett stort problem är också kemiska preparat som orsakar hudirritation och handeksem. Frisörer arbetskadeanmäler oftare belastningsskador och uppger oftare hudöverkänslighet än personer i andra branscher.Syfte: Syftet med studien var att beskriva i vilken utsträckning som ergonomiska besvär och hudbesvär förekommer på frisörsalonger i Gävleborgs län och om förebyggande åtgärder vidtas för dessa besvär.Metod: Detta är en retrospektiv tvärsnittsstudie med kvantitativ ansats med deskriptiv dataanalys. En webbenkät har skickats ut till 87 frisörer i Gävleborgs län, 50 personer har deltagit.Resultat: Resultatet visade att 36 av 50 personer uppgav att de hade ergonomiska besvär, främst från axlar/skuldror och nacke vilket förekom hos 25 personer. På de flesta salonger uppgavs att det fanns hjälpmedel för att förebygga besvär från nacke, axlar, skuldror, rygg och nedre extremiteter.

The purpose of this thesis is to investigate how childrens librarians at public libraries motivate their selection and their purchases of fiction for children and youth. The aim is also to find out what is felt like a problem at the selection process and what is not. Six childrens librarians have been interviewed in this qualitative study. On a basis of a theory of literature pedagogic perspectives the librarians were asked how they look upon purchase of fairy-tales, classics, pulpliterature and literature that contributes to the debate about man and society. They were also asked about their opinions of Bibliotekstjänst, of criticism of childrens books and how they reason about their purchases in general.

This study examines imagined boundaries between Swedes and non-Swedes. Rather than using pre-determined definitions as a starting point, the attempt is to examine the discursive construction of difference. The purpose is not to study the portrayal of immigrants per se but to examine how the ?immigrant-ness? is constructed. The result shows the perception of ?immigrant-ness? is linked more to a person?s origin than to the act of immigration itself. The selected newspapers are Dagens Nyheter (DN) and Svenska Dagbladet (SvD) for the period of 15th November ? 21st November, 1999.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

In central Jönköping, on Munksjöns northern waterside a shopping centre will be built, on the block Atollen. The construction will begin in autumn of 2007 and will be finished according to plan in 2009. Atollens goal is to counteract the competition from external retailers and strengthen the retail trade in the city centre, leading to more attractive and competitive city centre.Atollen will not be a shopping centre in traditional style and design, it will be focused on shopping and experience. The shopping centre shall be a natural venue with a wide and exclusive store mix, concentrated against trend conscious customers. This will be created with the help of a futuristic design and architecture, with light, open and transparent spaces.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.
