Extrem-/äventyrssport innanför gymnasieskolans väggar
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.
Inverkan av flisig krossballast på betong
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.
Flaskhalshantering genom materialstyrning : En fallstudie på LB-Hus
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.
Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods
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).

FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA
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.
Beräkning av pumpkapacitet samt konstruktion av pumpfundament
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.
Brunnsviken : Utvärdering av åtgärder för förbättrad vattenkvalitet
Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin. The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.
Implementering av verksamhetsbaserad arkivredovisning i statliga museimyndigheter
The change that has occurred during the past few decades concerning the development of electronic records, information technology and the constantly increasing quantity of information, have confronted the archival discipline with new challenges. In the digital world, the concept of ?record? has changed from representing something lasting and physical to something much more abstract and transient. The way to approach archival description has also changed, from focusing on the static preservation of archival records, to documenting the transactions of organisations, and to clarify operational processes. The discussion about the general purpose of the archival discipline, and its place in a changing world, has led to a new approach to archival description.
Energiaspekter på gestaltning : fallstudie Energihuset i Uppsala
This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.
Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Syftet med denna undersökning var att utforska den lärandes perspektiv genom att lära oss spela ett nytt instrument. Genom att försätta oss i en sådan situation och sedan granska våra egna läroprocesser hoppades vi kunna bemöta våra framtida elever med djupare förståelse. Vi ville på detta sätt försöka synliggöra faktorer som påverkar vårt lärande och bilda oss en uppfattning om hur vi påverkas av dessa.Undersökningen utfördes med oss själva som studieobjekt där vi under hela processen noggrant förde dagbok över våra upplevelser, både skriftligt och med ljudande inspelningar. Inspelningarna bifogas som en bidragande gestaltning till det avsnitt som kallas Processen. I Processen förekommer diskuterande tolkningar som fullföljs i Epilogen.Vår studie visar att det är svårt att till fullo sätta sig in i en nybörjares roll.
Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.
