Utveckling och utförande av frekvensstudie vid Rapid Granulator AB

The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.

Ytterväggar : En jämförelse och livscykelskostnadsanalys

This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..

Jämförande LCA av engångssängkläder och tvättbara sängkläder i sjukvården

Inom sjukvården används ? precis som överallt där människor sover ? sängkläder av hygienskäl. Problem med smittspridningar av typen multiresistenta bakterier (MRSA) och spridning av andra sjukdomar har drivit företag som Cellcomb i Karlstad AB till att utveckla engångssängkläder för att förhindra detta. Engångssängkläderna är skyddade av en biofilm som ska ge ökat skydd mot bakterier och fungerar som en barriär så att inte vätska tränger igenom. Problemet är att det inte finns mycket till underlag för hur engångssängkläderna står sig mot vanliga sängkläder ur miljösynpunkt.

Är det effektivt? - En studie av ett företag och dess förvaltning av datorbaserade system

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

Kan man läsa Call of Duty 5? - om det vidgade textebegreppet och elevers fritidstexter i svenskundervisningen

Syftet med min undersökning är att ge en bild av hur lärare kan förhålla sig till det vidgade textbegreppet och hur lärare och elever kan förhålla sig till elevers fritidstexter. Det empiriska materialet är insamlat med hjälp av kvalitativa intervjuer. Informanterna består av två lärare samt sex elever, tre från sjunde och tre från åttonde grundskoleåret. Mina resultat visar att ingen av de två intervjuade lärarna visar sig kunna definiera det vidgade textbegreppet, men de ställer sig positiva till en vidgad läsning. Dock tillämpar ingen av dem en sådan i någon större utsträckning.

Textil och glas ? ett universum

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

Krav på exportlicens vid gränsöverskridande transporter av farligt avfall inom EU

The purpose of this essay is to draw attention to the obstacles that affects the internal trade of waste within the EU. The essay doesn?t in any way encourage pollution or illegal handling of waste but unfortunately there are large profits to be made from illegal destruction and recycling of waste and especially hazardous wastes. Therefore the dependable companies handling waste must access a market with fast and flexible (but predictable) regulations as well as lower transaction costs to help make the environment better and encourage a strive for increased recycling. There are examples where some waste only can be sent to a land-fill within the country but could be recycled in other EU-countries.

Energieffektivisering på Skutskärs Bruk : Varvtalsstyrning till utvalda pumpenheter på Blekeri 4

In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.

Du vet ju vad vårt styrdokument säger... : En essä om det mätbara och det svårmätbara lärandet i förskolan

My essay begins with two stories showing two different perspectives when looking at learning in preschool. These two different learning styles I have chosen to call, the measurable and the difficult to measure learning. As a pedagogue I am involved in both events. In these events I describe how different we pedagogues interpret our governing documents on children's learning. By describing how the educational activities are designed differently in the two events, I try to highlight the pedagogues views on learning in preschool.

"Var är Emma!?" : En essä om integrering av barn med problematik i skolan

This essay contains two stories that reflect the reality I face as an educator, as well as a reflective discussion about my self-perceived dilemma. The dilemma reflects a classroom situation where I as an educator have trouble dividing my focus, my focus is either put on entire the class or on the child with special needs. Through this self-perceived situation I have started to question how children with special needs find their place in the school today. I discuss how I can handle and look at the unique situation that occurs when meeting this child.Terms like integration, inclusion, segregation, social rights and the expression "a school for everyone" will be discussed in this text, as well as how we can connect these terms and expressions to the problems I find in the school system?s way of handling children with special needs.I also highlight my dilemma from different ethical perspective.

Cyklisters situation på 2+1-vägar

In this report the situation for cyclists on 2+1-roads is analysed and studied. Theseroads are often the old 13-meter roads that have been changed into 2+1 to increasethe security. Two road sections outside Motala in Sweden has been deep studiedand analysed. The different parts in the planning process show how the progressgoes. To begin with the change should be within the old 13 meters but after thepilot study was circulated for comments the result became a broadening to 13,75and 14,00 meters.

Revision i småföretag : Ett nödvändigt ont?

Syfte: Vårt syfte med denna uppsats är att, via egna studier och genom att beakta den aktuella debatten, undersöka om revisionsplikten i små företag är nödvändig. Vi vill ta reda på hur stort intresset är att avskaffa plikten i Sverige och dessutom vill vi se vad avskaffandet har inneburit för andra länder.Metod: För att uppnå vårt syfte, har vi genomfört en intensiv studie där vi grundligt har undersökt några få enheter. Datainsamlingen som ligger till grund för vår uppsats är deduktiv, då vi bygger förväntningarna på tidigare empiriska rön och teorier. Vår undersökning är baserad på en redan befintlig debatt och vi vill veta om den accepteras eller förkastas. Således har vi använt en kvalitativ ansats där vi har inhämtat information från fem intervjuer, varav två intervjuer genomfördes med småföretagareResultat & Slutsats: Efter att ha ställt vår empiriska undersökning mot tidigare teorier, har vi kommit fram till att det finns skäl att ifrågasätta revisionsplikten i småföretag.

Pedagogers tankar kring anmälningsplikten enligt Socialtjänsten [Teachers thoughts about the duty to report according to the Social Services Act]

Syftet med vårt examensarbete är att beskriva pedagogers tankar kring anmälningsplikten och vilka hinder som kan uppstå i samband med anmälningsplikten enligt Socialtjänstlagen 14 kap. 1 §. Vi vill med arbetet också förbereda oss inför kommande anmälningssituationer i våra yrkesliv och önskar att arbetet ska bidra till diskussioner kring ämnet på skolan där vi gjort vår undersökning. Våra huvudfrågor har varit: Vilka tankar har pedagogerna kring anmälningsplikten? Vilka hinder kan uppstå vid tillämpning av anmälningsplikten? Resultaten har vi nått genom litteraturstudier och intervjuer.

Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.
