Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

Flervariabel reglering av industrirobot

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

Kvalitets och förbättringsarbete för ITtjänsteföretag

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

Ormens metaforiska skepnader

The purpose of this thesis has been to explore in what ways Franz Kafka?s ?The Metamorphosis? can be read as a story of gender. By bringing together Judith Butler?s theory of materialization and Lennard J. Davis?s crip theory I have spoken of Dismodernity as the domain of abject bodies that have been repudiated by (post)modern societies as untintelligible and dysfunctional.

Arbetskravsanalyser av arbetsuppgifter i Hälsans trädgård i Linköping utifrån The Revised Handbook for Analyzing Jobs (RHAJ)

Hälsans Trädgård is a project which is going to start in Gamla Linköping, Sweden. The authors were commissioned by Arbetslivsresurs, a company working with work rehabilitation, to select, define and make job analyses on five work tasks at Hälsans Trädgård in Gamla Linköping. A job analysis means an analysis of the demands the job make of the individual. The job analysis used in this study is called The Revised Handbook for Analyzing Jobs (RHAJ) and is from the US Department of Labor (DOL). As RHAJ is an American instrument, the authors produced a form where the concepts are translated into Swedish to make the analysis easier.

Tredje generationens flugfiskerulle

This Master Thesis describes how a concept for a new fly fishing reel has been developed. Thethesis has been an interwork with Loop Tackle Design, which is a leading company in the flyfishing industry with their high-quality products. Loop designs and develops all types of flyfishing equipment like fly fishing reels, rods, lines and clothes.The purpose of this thesis is to generate a concept for a new type of fly fishing reel. The new flyfishing reel shall be innovative and reduce the number of components in fly fishing equipment.The solution for this is to create a fly fishing reel that is collapsible and can be used for all typesof fly fishing.The thesis started with a history of fly fishing and the equipments that have been used for flyfishing in the past and what is used today, in order to get an idea how fly fishing haveprogressed. A frame of reference was then compiled to get an idea of the forces and surroundingsa fly fishing reel will be exposed to.

Analys ac konstruktionsprocessen inom FTC

This thesis work was made to optimize the writing of the construction specificationsat FKA. These construction specifications are created before each plant modificationsthat is started because requirements from the Swedish radiation safety authority(SSM) and internally on Forsmarks nuclear group as constructions / implementationdocumentationThe study was done through seven interviews of two people at three different groupsinvolved in the construction specification and an interview from the group accreditedverification. The four selected groups were selected through an extensive analyticalwork resulted in an elimination matrix where these four groups was considered to bemost involved with the construction specification.The questions asked to these individuals were based on the instructions and sampletext that are described in the construction specification. To ensure the quality of thethesis were to limit itself to the chapters that were considered most relevant toimprove. The analysis revealed a number of points that should be improved, partlyinto the routines when writing the construction specification and when ether sampletext or suggestions should be changed and complemented.

Hybridlärkens tillväxt i Snogeholm : hur påverkas produktionen i blandbestånd jämfört med trädslagsrena bestånd?

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

My task is to come up with a good idea that facilitates the coupling of trailers, i.e. from an idea to a fully functioning prototype. The product is intended for use by all customers for all kinds of trailers. The actual goal of the work is to develop a full prototype that you can install and use in the easiest way possible, a prototype that follows the specifications.

Naturlig föryngring efter markberedning med harv eller Bracke Planter i Småland

Studiens syfte var att jämföra Bracke Planter (BP) med harvning med avseende på andelen markberedd areal, uppkomsten av naturligt föryngrade stammar av olika trädslag per ha och huvudplantors medelhöjd tre år efter plantering. Jämförelserna mellan de två metoderna gjordes gruppvis med lika antal inventerade trakter för respektive metod, inventeringen gjordes i Småland under augusti månad 2012. För att fastställa andelen markberedd areal mättes arean på markberedningshögar och harvspår på årsfärska markberedningar (6 trakter). Förekomsten av naturlig föryngring och höjd på huvudstammar (ca 550 mätta plantor/metod) registrerades för totalt 16 trakter. Andelen markberedd areal var signifikant högre för harv än för BP, ca 33 % jämfört med 22 %.

...de bultades till bättring : till frågan om Sveriges kristnande

The written sources concerning the process of christianization in Sweden has for a long time been limited to two main texts, Rimberts vita of St. Ansgarius and Adam of Bremen´s History of the bishops of Hamburg. This is due to a rigid source criticism in the beginning of the 20th century, which put other material ? in particular the norse sagas ? out of consideration. The last twenty years however, new questions have been raised concerning the christianization, partly because of new archaeological findings, new interpretations of the significance of runic stones and the recent debate about the formation of the Swedish medieval kingdom.
