This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Buller påverkar människor på många olika sätt, både fysiskt och psykiskt. Hörselskador, tinnitus, sömnproblem och koncentrationssvårigheter är några av effekterna av bullerstörning. Intensivvårdsavdelningen är en arbetsplats som är dokumenterat bullrig. Sjuksköterskor på intensivvårdsavdelning utsätts i sitt dagliga arbete för en hög bullernivå. Det är en apparattät och tekniskt avancerad miljö.

This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

Ljudnivån på intensivvårdsavdelningen är hög. Övervakningsutrustning och medicinskteknisk apparatur bidrar till bullret med sina larm, patientgruppen på intensivvårdsavdelningen är mycket personalkrävande och den höga personaltätheten bidrar till den höga ljudnivån. Forskning visar att buller påverkar arbetsprestationen och kan medföra att det blir svårare att genomföra en uppgift. Mänskligt tal är mer distraherande än annat buller även vid låga ljudnivåer. Syftet med studien är att beskriva hur sjuksköterskor inom intensivvård upplever att buller påverkar arbetsprestationen.

The purpose of this essay is to explore how I can meet children with different kinds of attention deficit disorders. What can I do when the child kicks me and makes me cry? How can I handle it right so that the child and I can feel good? In my text I am writing about how I can prioritize my way when I am angry. I wonder how to prioritize my feelings and feel safe with the other person. I am developing these questions in my text.

To investigate if the student?s school centeent, and that planning of the school lunch is done from a health perspective. Qualitative research approach was used, including both interviews and observations, to view the purpose. Evidence was collected using a participating observer, semi constructed questions and structured observation. To focus on specific parts in the material, a directed content analysis was used. One large and one smaller school participated in the study.

The data acquisition system COMET developed by Saab AB contains a unit for signal conditioning and A/D conversion, called KSM. The varieties in signal conditioning constitutes of a number of specific PBAs and maintenance as well as reconfiguration of these are complicated not to mention costly. This thesis has aimed to investigating whether the signal conditioning circuits can be replaced by a general purpose, programmable solution. If so, how can this be done? The development has been carried out by evaluating ideas through the use of a laboratory environment and has resulted in an analog design for laboratory purpose.

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

My essay is on the subject of teachers work environment with focus on noise and communication. In the essay questions are raised on how a teacher can influence his or hers noisy work environment. A school is a large work place with many employees and is owned and administered by the county municipality which is an even bigger workplace. How big an acting space does a teacher have in such a large organization?My methods of research on these questions have been to conduct interviews and analyzing documentation from The Swedish Work Environment Authority.

It is statutory that teachers shall document their student's development of knowledge in different subjects. The teachers employed by Sundbybergs municipality have been commissioned to do the documentation in the web-based electronic system Projekt- och Omdömesdatabasen, P.O.D.B. The purpose of this study was to investigate witch effect the IT-solution P.O.D.B has brought for the teachers in their task of student documentation. By conducting interviews and questionnaire studies I have been looking for answers to if the target achievements have increased by using the IT-solution, and if the teachers are aware of what they may or may not write about their students in the system. The conclusions I have been able to draw through my studies are that the teachers have accepted the commission to use P.O.D.B.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..
