Ständiga förbättringar i lagerverksamhet på Nedis AB
The thesis has been carried out at Nedis AB in Jönköping. The aim was to develop proposals on approaches that could help the company to continually improve their warehouse operations by eliminating unnecessary operations, making the warehouse more structured and how they better could use the staff's suggestions for improve-ment. The collection of data consists of observations, interviews with a total of nine people from the staff of Nedis AB and a benchmarking conducted at Husqvarna AB. A number of shortcomings and weaknesses in procedures at the warehouse were iden-tified. Packing stations were not standardized and they were seen as poorly structured and messy.

Bedömningsgrunder och reningskrav för avloppsreningsverk, 25-2000 pe, i Laholms kommun
The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.
Value stream mapping i praktiken : En fallstudie på Light My Fire
Titel: Value stream mapping in practice ? A case study at Light MyFireAuthors: David Rydman and Tomas ÖnnemarMentor: Veronica Ülgen SvenssonExaminer: Åsa GustafssonBackground: Companies push their prices in today's markets to be competitive, which means that companies need to find ways to reduce costs while maintaining profits. (Cudney, 2009) According to Bergman and Klefsjö 2007, the basic rule of quality improvement says "there is always a way to achieve higher quality at a lower cost". One way is to improve a company's processes to get a more efficient flow and improvements that may cut costs. (Bergman & Klefsjö, 2007) Why it's important to look at the processes are that they often contain waste that can be eliminated.
Att umgås eller inte umgås, det är frågan! : Socialt umgänge och utveckling hos människor med psykosdiagnos
Background: A common view about people with diagnosed psychosis is that they are socially withdrawn and that they neither cope nor want to engage in social relationships. Newly published specialist books on this subject also support this view.Aims: To unveil further dimensions of the phenomena by explorative analyzing consumers? own depictions about their ?social relationships".Method: The material is taken from a larger study that followed consumers regularly during a lapse of 3 years. Within this material 15 interviews from three respondents were chosen, a selection which gives maximal spreading concerning age, sex and background. The interviews where analyzed by methods based on Grounded Theory.Results: Three main dimensions were identified: supportive relationships, difficulties and social withdrawal.
Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Ständiga förbättringar inom verksamhetsprocesser : en studie mellan läkemedel- och kärnkraftindustri
The purpose of thesis was to investigate and compare how two companies within pharmaceutical industry and nuclear power industry are currently working with quality development regarding continuous improvement and Lessons Learned in business processes. In addition, a simple comparison was made with the automotiveindustry.McNeil AB are improving their processes continuously and are according to the findings of this report performing well in their pursuit of world-class pharmaceutical production. They have a well functioning process regarding improvements proposed in weekly improvement meetings engaging all employees. However, during interviews it was made clear that the functionality of the process which administer improvement proposals generated in addition to, or beside the weekly improvement meetings, were inadequate. McNeil AB is proposed to administer this through an IT solution instead of by paper and e-mail, that simplifies the process of adding, implementing and follow up an improvement proposal.The nuclear power plant Ringhals AB recently made major improvements in their business processes as well as the plant itself.
Dubbelkönighet hos mört : normalt eller miljöinducerat?
A number of chemical agents, and their degradation products, have been
recognized as having estrogenic activity on animals. On fish they interfere with
endogenous estrogen and in many cases mimic its activity, thus increase estrogenic
reponse, with elevated levels of vitellogenin. Hence they are called Endocrine
Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of
exposure to estrogenic pollutants. Wastewater from sewage treatment works
contains chemicals known as EDCs, and there are evidence of roach (Rutilus
rutilus) living in recipients of such wastewater having traits of both gender, i.e.
oocytes in male gonads (intersex) on histological examination.
This study was done on roach living in Lake Funbosjön Uppland, Sweden.
Biologisk reducering av nitrat och nitrit i vatten
During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.

Produktivitetsstudie Brobyggnad
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar
Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.
Upplyst trapphus
The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.
Analysera mera för bättre kvalitet i förskolan
Abstract The Act of Education outlines that good quality in schools and preschools, focusing on continuous improvement, promote children?s learning and this in turn is on of the most important factors for child and youth welfare.This thesis was based on the authors´ pre-understanding that there are opportunities to improvement in the quality of preschools. The focus was on studying how analyses can provide a base for quality work, and the purpose of this study was to identify and describe the analytical methods that can be used in the process of continual improvement for quality development in preschools.A qualitative study was conducted in two preschools that have received quality awards. It was conducted through interviews with the preschool principals and through studies of various documents.In the comparative analysis of theory and empirical data, it was made clear that there was a regular analysing process going on at the investigated preschools and an emphasize of reflection could also be identified. Keywords: Quality development, preschool, analytical methods, processes, reflection .
Betydelsen av verbal uppmuntran vid utförande av handstyrketest
The purpose of this study was to evaluate if verbal encouragement had any influence on handstrength measurements. Twenty subjects participated in the study, all women between the age of 20 and 62 years. A standardisation of testing conditions and verbal encouragement were designed. Three measurements were conducted during two days using T.K.K 5401 Grip D. First there was a trial set, and then Test 1 (without verbal encouragement) and Test 2 (with verbal encouragement) were conducted.
