Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

This reportcommunicates the processes and results of my degree work in industrial design at candidate level at Umeå Institute of Design.During my degree work I had a cooperation with Svenska Jägareförbundet (Swedish Hunters Assosiation).The aim for my project has been to explore how I could make hunting a safer hobby and undertaking. Every year people get seriously injured and in average 2 people a year dies  due to hunting accidents. My goal is to identify problems within the hunters communication and approach. Through a creative design process I will find a valid  nd realistic solution to these problems. My project will be presented as a conceptual solution  hat will be based on currently existing technology.

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

The essay describes the bachelor project by Marie Hanås, in collaboration with Skälsö Arkitekter. Skälsö Arkitekter are currently developing an area in the north of Gotland, Bungenäs; previously home to lime stone quarries and military bases.The brief was to design a set of outdoor furniture to complement the new development. The main effort of the project was in designing furniture that would fit the environment visually but construction issues were a major secondary concern, to ensure the easiest possible manufacturing. A reference group of coastal house owners were interviewed, and their feedback, together with an analysis of functions, trends and target groups, were the base for the ideas.Of the five concepts presented, Skälsö Arkitekter chose one to develop further. This was done through sketches, models and 3D models and led to the final result which is lightweight furniture of Gotlandic pine wood with an industrial touch.

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM?s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.In the Swedish system, SSM?s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility.

Energy is today a very common topic, not only in Sweden but in the whole Europe. In EU they have given out a directive 2002/91/EG about buildings energy use and throw this they have forced their members to show how much energy their buildings use. In Sweden has the gouvernment established a law (SFS 2006:985) about energy declaration for buildings which demands that the building owner needs to show how much their buildings energy consumption are. Important to know is that this law doesn´t applies for industrial buildings.The report will show what the new law about energy declaration for buildings and appurtenant directions will mean for Riksbyggen. Also energy calculations will be done to be able to compare Riksbyggen buildings with the new law and directions.

This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.

Relationships and trust between humans create the psychosocial working environment. This is a basic human activity and is communicated in a continually ongoing process. Conciseness about the value of trust and social capital motivates the need for work, with threats to communication, being conflicts and noise. This can create greater trust in the workplace as a whole, as well in the working team. Scientists are increasingly interested in these social relations in the working environment; there are profits, both for production and in terms of individuals2019 well being, in shifting the focus away from a purely production-oriented, economic perspective.

I och med att intresset ökat för produktivitetsförbättringar, med början under tidigt 1980-tal, har FM blivit mer och mer intressant för företag. Detta då de insett vikten av att stödjande funktioner måste hinna med i utvecklingen av kärnverksamheten för att ökad effektivitet skall kunna erhållas. FM beskrivs som ett sätt för företag och organisationer att samordna, organisera och sköta de stödfunktioner som krävs för att kärnverksamheten skall kunna bedrivas och bli så effektiv och produktiv som möjligt. Stödfunktionerna kan antingen utföras i intern eller extern regi. Med kärnverksamhet menas det som privat och offentlig sektor ser som sin huvuduppgift.Den här uppsatsen är skriven i syfte att förtydliga begreppet FM, som kan uppfattas som relativt svårgreppbart.

Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv. Syftet med examensarbetet var att undersöka om det är möjligt att industriellt producera ljusemitterande vävar med optiska fibrer. Arbetet delades upp i olika delar, både teoretiska och praktiska. Den teoretiska delen innebar informationssökning inom olika medier, såsom vetenskapliga artiklar och intervjuer med insatta människor inom de berörda områdena. Den praktiska delen i examensarbetet bestod av flera olika moment.

According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

Personer med funktionsnedsättningar stöter ofta på hinder i den offentliga miljön, till exempel trappor, höga trösklar, dålig skyltning eller belysning. Detta i sin tur påverkar individens förmåga att utföra dagliga aktiviteter och att vara delaktig i samhället. En pilotversion av ett kartläggningsinstrument användes för en bedömning av miljöhinder i ett urval faciliteter i en skånsk kommun. Av de 1215 miljöitems som bedömdes påträffades 298 miljöhinder. Generellt sett visar detta på relativt få miljöhinder vilket kan vara avgörande för tillgänglighet och därmed även påverka aktivitet och delaktighet positivt.

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

Individuell lönesättning är idag det dominerande lönesystemet både inom privat och offentlig sektor. Trots det är dess effekt relativt outforskad. En allmän föreställning är att det är ett motiverande och effektiviserande lönesystem. Uppsatsen utforskar hur individuell lönesättning fungerar som motivation för individen, om motivationen påverkas av att individen arbetar i ett gruppsammanhang, samt huruvida kvinnors upplevelse av systemet färgas av jämställdhetsdebatten. De tio intervjudeltagarna kom från en kommunal och en privat verksamhet.Resultaten visar att systemet upplevs som motiverande, men att även andra faktorer i arbetet motiverar och ibland är viktigare.
