The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

This thesis is conducted together with the environmental- and health department in Halmstadcommunity. The thesis is about allowance of bedding and water supply for pig farms inHalmstad community. These farms are chosen randomly from all of the pig farms inHalmstad community. It includes inspection of 27 pig farms and writing of a report. Duringthe inspections I study the amount of bedding, what kind of bedding, water supply andinjuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting.

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.

Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen. Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra olika gymnasieskolor i sydvästra Skåne. I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det var många faktorer som spelade in när lärarna beskrev varför de inte hade så många lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser, skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla, ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit ett stort fenomen i samhället.

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Title: Bottleneck management through materials administration Course:  4FE05EAuthors:  Mikael Karlsson and Johannes Mueller  Examiner: Helena ForslundKey words:  Bottleneck management, material management, process description, timber, proceduresPurpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.  Part.  1:  Identify  and  analyze the material management  connected to  the planing mill  in order to identify problem areas.Part.2:  Identify  improvement potential  in the material management connected to the planing mill.  Part.3: Suggest improvements in the material management connected to the planing mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.  Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

The purpose of this study was to investigate the reason behind thedecision by a company regarding the desire to use mobile access to theirERP-system and to discover whether this will involve any loss offunctionally in comparison to using the ERP-system on a computer atthe office. In addition, the pros and cons involved in using mobiledevices for accessing the ERP-system will also be examined. Semistructured telephone interviews were conducted with companies whicheither used or did not use mobile devices in relation to their work. Atelephone interview was also conducted with a consultant who isworking with the implementation of ERP-systems and mobile solutions.The survey showed that companies with staff working in the field assellers, service personnel and construction workers want to gain directaccess to their ERP-system so as to be able to act directly and takedecisions, to have the ability to provide more efficient order processingand to send out invoices more quickly. Those companies which have notopted to use mobile devices at work within this field are those whichare unsure of the connection to the Internet and the capacities availablewithin cellphones.

Uppgiften som låg till grund för denna uppsats, var att ge förslag på produktivitetshöjande åtgärder på Electrolux Distriparts godsmottagning. Vår avsikt var att tillämpa delar av Toyotas produktionssystem på den befintliga processen. Detta resulterade i en serie förslag som, om de tillämpas, drastiskt kommer höja produktiviteten i den aktuella processen..

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

This thesis includes a mechanical engineering design work performed incollaboration between ÅF and Halmstad University. The work is done by FredyOlsson?s methods of Principle- and Primary Construction and David Ullman?stheories of Design for Assembly.The group was commissioned by ÅF to produce a concept to narrow down theassembly time of today?s luggage doors by reducing the numbers of adjustmentoptions. They also wanted it to be easier to mount the assembly by making itpossible to adjust the door in a closed position. Today luggage door takes, with its10 adjustment possibilities, around 4 hours each to assemble and ÅF wanted anassembly time around 10 minutes per door.Initially a preliminary study was made where the group began reviewing today'sconstruction and mounting of rails and doors on buses.

Ett undersöknings- och utvecklingsarbete för att lösa ett problem med att dränkbara pumpar i ett vattenavrinningssystem gick sönder med perioder på två år i genomsnitt, utfördes i samarbete med Cementa AB i Skövde. Orsak till pumpars haveri söktes och fanns vara bristande rutiner och kunskap om det underhåll pumparna krävde. För att lösa detta problem utvecklades riktlinjer för nyinköp av torruppställda pumpar för att möjliggöra kontinuerligt underhåll. Då möjligheter för placering av torruppställd pump saknades utvecklades ett pumpfundament för placering av torruppställd pump. Krav för utvecklingsarbetet togs fram i samarbete med Cementas underhållsavdelning och teoretisk dimensionering av dränkbara länspumpars dåvarande volymflödeskapacitet utfördes.
