Since the beginning of the internet the criminal world has used the medium as a platform for operation.This dark web is a domain where illegal sites are flourishing due to the possibilities offered by newtechnology. Net-based criminal activity is a challenge for society as it uses hard proof technologicalsafety measures to avoid the law. Silk Road is the most prominent example, an online illicitmarketplace where drugs and illegal substances are being traded based on conventional e-commerceconcepts. This paper argues for trust as an important factor for the survival of illicit online trade andapplies existing theories on e-commerce and virtual communities. To identify patterns of trust andcommon trust-based issues among Silk Road users, a netnographic study was conducted on the site?sdiscussion forum.

The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.

The purose of the study is to increase knowledge regarding systematic enviromentarl work in an organization that works with road services. Work on the road is done in a hazardous environment with constant danger regarding the life of the individual. The site of the work varies in accordance with where the needs ae . This requires skilled workers capable of working independently and that they are experienced din doing their own risk assessments in accordance with the individual believes that the situation calls for work to be performed safely. The study was conducted with a qualitative research approach in which four employees of different positions, knowledge, experience and vision to work in a hazardous environment were interviewed. The focus rests on the organization, management, and individual aspirations for a safe and secure working environment. The study adds weight to the relationship between the purchaser of the work and the organization as a prime contractor due to the compexity of the organization.

Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.

Syftet för denna studie var att studera förekomsten av postoperativa sårinfektioner hos patienter som genomgått kärloperation med inguinal incision under åren 2008 till och med mars månad 2013. Undersöka skillnader gällande riskfaktorer inom studerad patientgrupp för förekomst av postoperativ sårinfektion samt studera om patienter som utfört endovaskulär metod under samma vårdtillfälle oftare drabbades av postoperativ sårinfektion än de patienter som inte genomgått endovaskulär metod under samma vårdtillfälle. Metoden som användes var granskning av patientjournaler efter utifrån studien utvalda specifika operationskoder. Granskningen av de 54 patientjournalerna skedde med hjälp av egenmodifierad tidigare använd granskningsmall. Studieresultatet visar att förekomsten av postoperativa sårinfektioner hos den studerade patientgruppen uppgår till 22,2 %.

Det elnät som vi nyttjar idag är uppbyggt sedan 1900-talets början och är byggt för att hantera den 50 Hz som används vid kraftöverföring. På senare tid har vårt elnät börjat nyttjas för annat än bara kraftöverföring. Det kan handla om kommunikation mellan apparater eller kommunikation till elbolagen för fjärravläsning av elmätare. Denna kommunikation sker på högre frekvenser än 50 Hz och sträcker sig vanligtvis från 9 kHz – 95kHz beroende på vilket system man använder. Det faktum att våra apparater har utvecklats i ett högt tempo har även det lett till att dessa använder en modernare teknik som alstrar högfrekventa signaler på vårt elnät. När nu vårt elnät, som är byggt för att hantera 50 Hz, utsätts för alltmer högfrekventa signaler så uppstår nya problem i vårt elnät och det jordsystem vi har idag är inte tillräcklig för att hantera de högre frekvenserna. Skyddsjorden som finns i våra hem finns för att förhindra att människor och djur skall komma att skadas av elektriska strömmar.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Many dogs in Sweden are put up for adoption at the Swedish buy- and sales site?Blocket?. This because in Sweden, rescue shelters mostly takes in dogs that have been confiscated by the police. The aim of this study was to investigate what kind of dogs that are put up for adoption and why owners put their dog up for adoption and also compare the results with those from other countries. 800 dog advertisements from ?Blocket? were collected in the study between January 31st and April 10th 2012.
