Askor från avfallsförbränning farligt avfall eller en framtida resurs
I Sverige ökar förbränningen av avfall som inte är ett helt definierbart bränsle. Detta är i mångt och mycket ekonomiskt och miljömässigt försvarbart genom den höga kvalitén på rökasreningen, som garanterar att en mycket liten del av föroreningar når atmosfären, utan dessa koncentreras i askorna. Avfallsaskor går till stor del till deponier och används där för sluttäckning eller för att deponeras, samt att en stor mängd flygaska transporteras till Langöya. Inom en tioårsperiod kommer deponierna vara sluttäckta och Langöya uppfyllt, samtidigt som mängden avfallsaskor ökar, vilket innebär krav på nya lösningar. Orsaken till att framförallt flygaskan klassas som farligt avfall är koncentrationen av tungmetaller och föroreningar som härrör från bränslet.

Background: Due to outsourcing, the material flows in the telecom equipment industry have undergone major changes, which in turn has imposed new challenges for packaging supplier Nefab who delivers to the industry. In order to achieve market intelligence, Nefab wants to map the material flows, and investigate possibilities of further reusable logistical packaging systems.Purpose: The purpose of this thesis is to describe the typical features of the logistical material flows in a technically based, rapidly growing industry, and analyze the driving forces and obstacles, which influence the selection of logistical packaging system. Procedure: After developing a theoretical framework consisting of general logistical theories and theories related to logistical packaging, we have interviewed companies in the logistics channel of Ericsson Radio Systems.Results: We have found the main characteristics of material flows in our investigated industry to be Variations in Demand, Focus on Time-to-Customer, and Globalization of Logistics Channels. Regarding driving forces and obstacles in the selection of logistical packaging systems, we have identified Transportation Characteristics, Customer Demands, Quality, Handling & Administration, and Current Packaging System as important factors..
A Comparison of Two Immunoturbidimetric Assay Methods for Serum Amyloid A in Cats.
The analysis of acute phase protein serum amyloid A (SAA) has recently been brought into clinical use in veterinary medicine. Some of the difficulties with incorporating the SAA method in clinical practice have been the expensive and rather large equipment required for the method. Due to these difficulties only larger clinics can afford to use the SAA analysis.The company Equinostic has recently developed a smaller instrument that costs one-tenth of a larger instrument. The instrument is named EVA1 and has so far only been used to analyze SAA in horses.The aim of this study was to investigate if the EVA1 instrument could be used to analyze SAA in cats. This study included 24 serum samples from cat, which were first analyzed twice on the EVA1 instrument and then sent to the Strömsholm Referral Animal Hospital in Sweden where they reanalyzed the samples using a validated reference method.
Establishment and evaluation of a Barley starch isolation method with focus on representability
The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.
Säkerheten på en byggarbetsplats : Förhåller sig Skanska och dess underentreprenörer olika till arbetsmiljösäkerhet?
Approximately ten people die every year at building sites in Sweden. Every year TheWork Environment Authority (Arbetsmiljöverket) receives 3200 accident reportsfrom the construction sector. The Swedish building contractor Skanska has the vision:?Zero accidents?. Only at Skanska Sweden, where this diploma work is preformed,350-520 accidents and mishaps are reported every year for the last 5 years.

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.
Servicekvalitet på Linköpings stadsbibliotek ? ur tre fokusgruppers perspektiv
The main purpose with this MA thesis is to examine how visually impaired, disabled and people with dyslexia define service quality at the public library of Linköping. The method that has been used is focus group interviews. A focus group consists of four to eight people who are joined together, without knowing each other before, to discuss a certain subject. The aim is to get a wide spread of answers. A secondary purpose is to examine how this method works.
High Orbit Ion Cannon : Går det att skydda sig?
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Utveckling av nytt koncept till processmaskin
Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
Undersökning av sågverks effektivitet med avseende på underhåll : Vikten av en kostnadseffektiv underhållspolicy
Det finns stora förluster i sågverk som inte framkommer av deras traditionella driftsuppföljnings¬processer. Strategiskt viktigt för organisationen är frågan vad företaget behöver göra för att bli effektivt. I detta arbete diskuteras mätmetoder av effektivitet med avseende på underhåll och hur effektiviteten kan mätas med hjälp av att beräkna den totala utrustningseffektiviteten (OEE). Arbetet beskriver också olika underhållsstrategier och processen med att införa en sådan policy på sågverk. Under en period av sex dagar beräknas OEE på fem sågverk.
Hållbarhetsredovisning : En studie kring skillnader mellan granskade respektive icke granskade företag
The purpose of this study was to examine the differences between non-audited and audited sustainability reports and in that way indicate the significance of auditing to the contents of a sustainability report. The study was delimited to include three companies that create sustainability reports according to GRI guidelines, and also have changed from non-audited to audited reports.The study is an exploratory study where we started from companies that follow GRI's standard and who have changed from being non-assured to assured and certified. In order to examine any differences we have started out from corporate sustainability reports and with the basis of these latter gather those changes which may have occurred during the changeover. We therefore chose to conduct a literature review on each company's non-audited sustainability reports and compare them with each company's audited and certified sustainability reports. Furthermore our study has been made on the basis of an assessment model based on the concepts of materiality, completeness and comparability.The study showed that the audited sustainability reports in all companies were more focused and more detailed about the aspects GRI established for the performance indicators.
Vilka faktorer påverkar beslut om förtida projektavslut? : En fallstudie av utvecklingsprojekt hos svenska industriföretag
Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.
