Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".

 Conclusion:Medical treatment may have a role in platelet count after transfusion. Since the TACSI platelets passed the quality requirements, and the vast majority of patients platelet count increased after TACSI platelet transfusion, the TACSI platelets will replace the old method to produce platelets at the Uppsala University hospital.  Methods: A new approach that pools 8 buffy coats (TACSI platelets) that were separated into 2 units instead of 4-6 buffy coats pooled to 1 unit was investigated in this study. After the platelets were extracted from the buffy coats their quality was controlled and subsequently the platelet product was evaluated in 96 patients. Results: The results showed that 80 % of the platelet units passed the European quality requirements. Further, the platelet count was increased in most patients that received TACSI platelets. Conclusion: Medical treatment may have a role in platelet count after transfusion.

The purpose of this master?s thesis was to find problems that occur in the production line at Atlas Copco Rocktec Division, in order to decrease the costs of defect in quality. When the problems were distinguished, the authors ought to choose the problem with the highest improvement potential. One request from the constituent at Atlas Copco Rocktec Division was to connect the improvement to the document The Way We Produce. The document provides information and values about Atlas Copco and consists of 10 principles to be able to reach their vision.

ABSTRACTProblems with high turnover in nursing has escalated during the last years both nationally and internationally. according to previous research job satisfaction and quality of care was connected to specific features of the hospital work environement. It was also recommended by Coomber & Barriball (2007) to analyze job satisfaction at ward level with qualitative interviews to get a deeper and more extended insight in which specific features are of importance.The aim of this study was to investigate and describe the experiance of job satisfaction in relation to quality of care from nurses perspective. This study was carried out at an orthopaedic ward with primary nursing as organizational context of care.Two focus group interviews were conducted, they comprised nine nurses with at least two years experiance of primary nursing. A qualitative content analysis with inductive approach was used in order to develop more detailed insights of potential factors influencing work satisfaction at ward level.

The purpose of this study is to investigate witch knowledge and thoughts children will have about the term of floating and sinking, and witch possibilities there is to make various knowledge visible in preschool physics through playing with water. The study also concern the differences and similarities between two different groups of age who have participated in the study. The study was carried out by an activity with participant observation and feedback interviews afterwards. The result shows that the possibilities to physics are many in preschool. The children expressed new thoughts and ideas who concern other phenomena in physics during the investigation and discussed similar experiments and material to examine.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

In our everyday life we are constantly affected by sound; at home, on our way to and from work, when taking a walk through the woods and when we sleep. In discussions about sound one often talk about noise and to what degree a certain noise disturbs us. The positive qualities of a sound and what sounds contribute to the experience of a good environment is rarely discussed. The question of sound and the quality of sound is given more attention through the expansion of Stockholm, the city is becoming both bigger and more crowded. This raises new questions concerning the planning of the city e.g. should the changes of the sound quality in a place be one of the aspects taken into consideration when planning new buildings, are there ways to improve the sound quality in new building projects? Can we even improve the quality of sound in existing places by simple means? I have chosen to study four different areas in Stockholm; Hötorget, Mariatorget, Berzeliipark and Norrmalmstorg.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.

Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.

The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.
