ITT Water & Wastewater (före detta ITT Flygt) tittar på att eventuellt genomföra en förbättring av ytbehandlingen av deras pumpar för att eliminera de rostangrepp pumparna utsätts för idag. Examensarbetets uppgift är här att analysera och beskriva miljöeffekterna av de nya ytbehandlingsmetoderna som företaget undersöker.Målet med studien är att få fram ett underlag och en rekommendation om vilken ytbehandlingsmetod företaget bör välja ur miljösynpunkt.De olika metoder som studerats är:? Järnfosfatering + ED-lackering? Zinkmanganfosfatering + ED-lackering? Oxsilan + ED-lackeringDessa metoder har jämförts med nollalternativet, vilket innebär att samma metod som tillämpas idag fortsätter att användas.Miljöeffekterna som studerats för de olika metoderna är:? utsläpp till luft och vatten? avfall? energiAv de tre nya metoderna samt nollalternativet är Oxsilan följt av ED-lackering det alternativ som ger minst påverkan på miljön. Metoden har inga utsläpp av flyktiga organiska ämnen till luft, inget farligt avfall bildas och det avfall som ändå bildas är litet. Metoden har även lägre energiåtgång än de andra studerade metoderna.2008:Nr 2 Teknik.

This essay is about leadership in libraries within the academic world, i.e. leadership in research libraries. To place our survey in a context we begin the theoretical review with a chapter about organisation theory. We dont think its possible to separate the leader from the organisation so we wanted to describe the organisation and its effect on the leadership. The next theoretical section is about leadership research.

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

The diegetic game world places high demands on how it is designed. It is common that game developers wants to create a deeper player immersion and some developers believe to achieve this by integrating HUD elements into the game world. To find out how digital games can rely on the design of the game world, we performed user studies on beginners who have very limited experience of playing digital games. By observing the beginners, we could discern the visual aspects in the diegesis that helps players understand the game rules and objectives because the beginners won`t make their choices based on previous gaming experiences. If players encounter a variety of difficulties to understand the rules of a game, then it will less likely be a successful game.

Fartyg använder sig av stora dieselmotorer för framdrift och för att producera elektricitet ombord. Motorerna samt diverse kringsystem har behov av kylning och till detta används kemikaliebehandlat vatten i ett slutet kylsystem. Vid tömning och läckage från systemet tenderar det kemikaliebehandlade vattnet att hamna med länsvattnet. Länsvattnet genomgår en reningsprocess innan det pumpas överbord. Denna reningsprocess är inte utformad för att avskilja kemikalier och dessa tenderar att hamna i havet.

In this study, cortisol in saliva and pain related behaviours in calves were used as markers of distress when comparing two different dehorning methods; scoop or cautery. We also investigated the effect of a non steroidal anti-inflammatory drug (NSAID), meloxikam, on postoperative distress after dehorning with either dehorning scoop or cautery iron. Twenty calves were dehorned on one randomly chosen side by scoop method and on the other side by cautery. Five months later, the effect on horn growth was investigated. Horn production was observed in seven of the calves.

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

The collective agreement contains many important provisions concerning the relationship between employers and employees. When a collective agreement applies in the workplace, both employers and employees are bound by it. However, only employers of those two, can take part in the collective agreement, and therefore negotiate the content of it.The purpose of this study is to answer the following question: Why are rules that has been interpreted in collective agreements not expressed in writing? Therefore, the Swedish collective agreement system will be examined, and a distinction between types of silent regulations will be made to find causes. The potential for workers to act on a collective agreement with quiet regulations will also be examined.Collective agreements are signed on three levels: central, union and local levels.

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

This masters thesis aims to explore the branch libraries in Kalmar municipality and their relation to the Information and communication technology ICTsociety. How do they adapt to and assimilate with, the ICT-society? What are their roles in local social networks and do they make a difference there? To answer these questions, critical discourse analysis, CDA, as founded by Norman Fairclough is applied to four interwievs with branch library managers. Other theorists used are Michel Foucault, Chaïm Perelman and Ludwig Wittgenstein. A solid description of todays society on different levels is also given.

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.
