En studie av en mindre kraftstation har gjorts i samarbete med Exencotech som forskar inom energi-återvinning. Deras kraftstation behandlar återvinning av värme från uppvärmt vatten som annars inte hade använts utan ansetts som ren förlust.Den studie som genomförts har gjorts på ett 100kW system med en så stor möjlighet till modularitet som är möjligt för anpassning och flexibel installation. Studien har även innefattat en 5kW prototyp och en modulär version av 100kW systemet upp till 0,5MW. Applikationen har som krav att framför allt minska volymen och storleken på systemet. Studien innefattar även en ergonomisk och användarvänlig inriktning vilket har påverkat designen och konstruktionen hos systemet.För att finna lämpliga lösningar och koncept till projektet har flera konceptgenereringar gjorts, liksom utvärderingar av lösningar.
Innovativ utmatningsteknik : Mediumstor bulkförvaringslösning
This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.
Basel II och fastighetsbranschen - en scenariostudie av de nya kapitaltäckningsreglernas konsekvenser för fastighetsbranschen
Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.
Relation för livet. En studie om ensamkommande asylsökande barn
The aim of this study was to describe and to analyze needs and social efforts concerning unaccompanied/separated asylum-seeking children. The responsibility for the reception of this target group was transferred on July 1, 2006 from the Swedish Migration Board to the municipalities that sign an agreement with the Swedish Migration Board. Eight qualitative interviews were carried out with representatives for transit-residents and assigned municipalities in Skåne. Our main questions were: How has the reception of unaccompanied/separated asylum-seeking children been planned, how do the municipalities and the transit-residents consider their needs and what is the level of qualifications and competence within the municipalities in order to work with unaccompanied/separated asylum-seeking children on the basis of social efforts? We chose to clarify our findings on the basis of the attachment theory, which is applicable during the critical emancipation phase that the vast majority of the unaccompanied/separated asylum-seeking children find themselves in.
Extern miljökommunikation i praktiken : en studie på fyra företag
Kraven på extern miljökommunikation enligt standarden ISO 14001 är få och vaga. Eftersom företagen själva väljer hur den största delen av den externa miljökommunikationen ska gå till är det intressant att se hur den då fungerar i praktiken. Syftet med den här studien är att undersöka vad den externa kommunikationen kan innebära i praktiken. Med hjälp av den kvalitativa intervjuformen har empiri samlats in från företagen; SAAB i Linköping, SIEMENS Industrial Turbomachinery, LFV, ALSTOM power Sweden AB. Genom en kvalitativ analysmetod har materialet från intervjuerna bearbetats.Vår studie visar att det finns flera drivkrafter som ligger bakom företagens miljökommunikation, dels är det krav önskemål från omvärlden och dels imageskapande.
Utveckling av arbetsmetod för DFA
Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.
Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
Sustainability reporting within the food industry : a case study of regional differences in the plant-based non-dairy industry
Sustainability Reporting has emerged and transformed over the past decades as a voluntary practice by companies across industries that desire to show proof of good conduct and environmental; social; and economic responsibility. As industrial food production is one of the largest contributors to contemporary environmental problems, it might be expected that reporting within the industry would be both well established and well understood.
Unfortunately, it is neither. In light of the food industry?s considerable environmental impact and the growing popularity of plant-based food as a more sustainable alternative to dairy products, this paper assesses and briefly discusses the Sustainability Reporting of two companies in the plant-based food and beverage industry. The research was designed to compare the practices of Europe-based Alpro and US-based SoDelicious, and this study has two major purposes: to describe the reporting of the case companies and to subsequently
compare their practices to the other as well as to global reporting standards.
The empirical study in this paper was conducted through content analysis.
Att planera för social hållbarhet i ekobyar :
This essay gives the reader an overview of the different problems and issues a landscape architect might meet, in the process of planning and realizing an eco-village. Its aim is to stimulate new ideas, based on the traditional, present and future working field of landscape architects. The essay does not claim to cover all imaginable aspects of social sustainability within an eco- village, but refers to the presented sources for further in-depth reading. Although the original focus has been on physical planning, the interviewees? words have been of big importance, and to a certain extent changed the constitution of this essay.

Municipalities? makes regular customer surveys to measure both independent schools as municipal schools ' quality. A common method for customer research and background studies is that parents and students are asked to respond to simple Web-based surveys. Customer satisfaction and/or customer dissatisfaction options are presented in tabular form, based on the percentage that expresses a particular position within a query.
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening
Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Vilken roll spelar chefer på mellannivå i en omorganisation : En fallstudie av Teliasonera
The economic development and industrialization that has taken place in many parts of the world during the past century has brought about a huge increase in economic welfare. During this process, it has repeatedly been debated whether the gains from economic development are shared by everyone or just a few. In the field of economics, vast research has been conducted on this particular subject ever since the 1950?s. The most famous contribution might be said to be Simon Kuznets article, Growth and Income Inequality from 1955 and the ?inverted U?-hypothesis that was formulated on the basis of that article.
