Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
Communicating criteria
In the light of the criticism from the Swedish Consumers? Association towards the actions of modern fund managers on the Swedish Sustainable and Responsible Investment (SRI)
market, discussions of change has increased. The reasons underlying a change and communication process are scarcely focused on. Thus, grounded on theories in the fields of
Critical Management Studies (CSR), Corporate Social Responsibility (CSR), change and communication, this study analyses how a change of implementing revised SRI
communication is carried out at Handelsbanken Asset Management, existing motives for the change in communication, and how key actors can affect the process. A participant observation and in-depth interviews were carried out enfolding a discussion that contributed
with a critical analysis and discussion, concluding external motives to be dominant and that key actors of the change process are influential to a various extent.
Skyfall över Västerås : en konsekvensstudie
Skyfall kan leda till stora konsekvenser för samhället, framförallt i en stad då den urbana miljön är känslig för extrema händelser. Västerås stad har tidigare drabbats av skyfall där följderna har varit kostsamma. Den senaste forskningen pekar på att intensiva regnhändelser kommer bli allt mer vanligt förekommande, därför är det intressant att undersöka vilka konsekvenser dessa regn kan leda till.En analys har gjorts med utgångspunkt från SMHI:s lågpunktskartering över Västerås. Utifrån denna kartering undersöktes vilka förorenade områden, bostadsområden, exploateringsområden, infrastruktur, vårdcentraler, skolor, nätstationer och prioriterade pumpar som ligger i lågpunktsområden. Denna jämförelse har gjorts i ArcGIS.
Journalistik på liv och död En kvalitativ studie om journalisters syn på medias roll i asylprocesser!
The main purpose of this thesis is to explore journalists? views of the role of journalism in the asylum processes. The potentially problematic phenomenon is growing, and its spread will affect the way publishing decisions are made in the future. The subject is new and foreign to many journalists, and little to no research has previously been done on the subject. Our study will therefore provide new insight in the field of journalism ethics.We have conducted a qualitative study based on interviews with eight Swedish journalists who in oneway or another have reported on threatened asylum seekers.
Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning
The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.
Näringsbelastning på en anlagd våtmark från åker, skog och enskilda avlopp :
This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).
Kvalitetssäkring av markberednings- och planteringsuppföljning hos SCA Skog AB Jämtlands skogsförvaltning :
Quality assurance means to systematically work for better understanding of the customers needs, demands and expectations. The goal for this study was to investigate how quality can be assured in the job follow up that is made by forestry contractors after soil scarification and planting. The study consisted of a description over the current follow up process at SCA forest AB Jämtlands forest administration, analysis of current follow up situation and an investigation of follow up process made by contractors in other line of business.
The first step was a statistical comparison where the own follow up made by contractors were compared with follow up made by SCA them selves over 100 stands. Two soil scarification contractors and two planting contractors carried out the silvicultural measures. The results showed that significant differences between a number of quality factors measured, for example number of approved plants or approved scarification points, average score on stand and number of totally planted plants.
Implementation av Network Admission Control
This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.
BI M i förvaltningsskedet med avseende på konstruktion.
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
Kreditgivningsprocessen : Hur humankapital och risk bedöms vid kreditgivning av nyetablerade småföretag
Small business enterprises have escalated in Sweden during the last decade. However, new established companies are struggling to maintain their selves during the startup process and according to a survey from Tillväxtanalys, only 68 % of startup companies from 2008 were still active three years later. One of the main reasons is lack of capital and the most common approach to finance companies is to apply for a bank loan. In other words, commercial banks are of great importance for new businesses. Although, the problem arises when there is no previous history from the new businesses that the bank could base its credit assessment on.
Volatilitetsprognoser på den svenska aktiemarknaden: Tillämpning av Arch Typ modeller
This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
Kompostering av organiskt avfall från Gästrikeregionen ? miljöpåverkan av olika behandlingsalternativ
In the coming years, organic food waste will be collected in the region of Gästrikland, Sweden. The collection is planned to cover the entire region by the end of year 2007. To start with, smaller amounts are being collected and transported to a central composting plant in Sala. However, a central composting plant in the region of Gästrikland is projected.The objective of this thesis is to evaluate a number of possible methods for composting of organic food wastes regarding their environmental impacts and localization.There are four scenarios for future composting of organic waste that have been evaluated. There are two that consist of membrane composting, either in Sala or in the region of Gästrikland.
Stavelsen som enhet i läsinlärningen : Ett specialpedagogiskt perspektiv
The aimof this study is to contribute furthermore to understand the complexity of theprocess of learning to read and write in an inclusive environment. It focus on the syllableinstead of the phoneme as a unit in this process which is not the most common way ofdoing it. The report is based on a qualitative analysis of this task in pre-school and gradeone at a primary school in a small municipality.In the result, I have found, that the very structured working process and the diagnosticapproach helps the teachers to understand on what level pupils are at. The pupils whostart working this way in pre-school, feel safe knowing what is expecting from them andthey also learn from each other. All pupils in grade one have, before w 45 in autumnterm, very good letter knowledge and have learnt how to read words with two syllableswith a consonant-wovel-structure.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
Effekter av tidiga reflektioner vid musikreproduktion
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
