E-handeln är det nya svarta ...så var noga med hur du stylar den.
Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.
Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand
During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.
Kalciums och magnesiums inverkan på arsenikavdrivningen i virvelbäddsugnen : The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.
Eftervårdens implikationer : En kvalitativ studie om terapeuters arbete med utsluss och eftervård i en integrerad behandlingsprocess
AbstractThe term aftercare is largelyexplained by means of the contextual and ideological conditions for treatmentwhich are to be found in juvenile care facilities. The development of the livesof young people who have been placed in care facilities is dependent ontherapeutic relationships, professional separations, continuing follow-ups andan even transition from control to autonomy. The aim of this study was toexamine the steering mechanisms behind the execution and planning of aftercareat a youth facility for care or residence. The aim was further defined throughthe specification of the following questions: 1. How are the concepts ofresocialisation and aftercare define and delimit? 2.
- För vi har slutat nian, fyfan va' vi é bra! : En kritisk diskursanalys av grundskolans fostran från Lgr62 till och med Lpo94
I have studied the curriculum for the compulsory Swedish school, from the curriculum from year 1962 when the Swedish grundskolan became a reality, to the curriculum from year 1994, the one in practice today. My primary interest has been what the curriculum says about bringing up the Swedish youth. My theory has been the British analyst Norman Fairclough?s Critical Language Studies. His thoughts about actual discourse, type of discourse and order of discourse has led me through out this essay.
Fem år med MiFID på svenska värdepappersmarknaden och dess inverkan på mindre investerares förtroende
Background: Markets in Financial Instruments Directive, MiFID, was implemented in Swedish law in 2007 and aimed to increase competition of the securities market in order to achieve efficiency and lower transaction costs and to enhance investor protection. Another aim was to increase confidence in the market. After the implementation of MiFID some doubts had been highlighted regarding its intentional effects. This evoked the authors? interest to examine the directive?s effects and its impact on investors? trust.Aim: To examine how various participants in the Swedish securities market experienced changes since the implementation of MiFID in 2007, and its impact on the securities market and minor investors' trust.Method: The study applied a qualitative method with a deductive approach to describe, interpret and understand the problem area.
Utvärdering av lockmedel för marklevande predatorer under midvintermånader i Norrbottens inland
Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used.
In this study three kinds of different lures was tested against each other?s.
Bärförmågetillväxt i pålad friktionsjord
Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.
Effektiva gränsorganisationer: en fallstudie av regionkontoret North Sweden European Office
Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and Västerbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.
Näthat : I gråzonen mellan straffrättsligt ansvar och yttrandefriheten
The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.
Skadlig kod och sårbarheter i Windows : En studie i virusens historia och nutidens olika säkerhetsrisker
I dag kan man oftast läsa om olika säkerhetshot och risker en datoranvändare måste tänka på för att inte ge någon utomstående möjlighet att komma åt känslig och/eller privat information. Här talas det om nya virus och nya typer av trojaner som sprids som epidemier över Internet, och i bland handlar det om ett spionprogram som följer med en nedladdad fil. Det är svårt att hålla reda på alla typer av skadlig kod som nämns fast med ökad förståelse ökar också chanserna för att klara sig från smitta. Det har visat sig att utvecklingen av skadlig kod är lika stark som den inom kommersiella mjukvaror. Från persondatorns uppkomst i början av 80-talet och fram till i dag, har utveckling skett i alla områden av den skadliga kod det handlar om strategi, syfte och framförallt ren kodkomplexitet.Dagens ledande leverantör av operativsystem och webbläsare, Microsoft, lovar allt mer sofistikerade säkerhetslösningar varje gång en ny version av ett program släpps.
Det vi vet när vi glömt allt vi lärt oss : den politiska debatten om utbildning för nyanlända elever på 1970-talet och 2000-talet
The purpose of the present paper is to examine the political debate on the education of newly arrived immigrant pupils at secondary school age. The following issues are under scrutiny:What are the goals, expressed by politicians during the examined periods, for the education of newly arrived pupils?What ideas about education and what educational ideals can be observed in the political debate on the education of newly arrived pupils?Has there been any change, during the examined period, in the policy debate on the education of newly arrived pupils?The research material consists of reports and statements of the Education Committee, as well as a number of parliamentary protocols. Two five-year periods, 1971-1975 and 2006-2010, are studied and compared. All in all, the material consists of 23 documents issued during these periods.
Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Det etiska ledarskapets roll i kampen mot korruption - En studie om antikorruptionsarbete i den svenska banksektorn
Despite Sweden's ranking as one of the least corrupt countries in the world, recent studies suggest that the prevalence of corruption in the private sector is growing, now approaching international levels. Over the past couple of years, Sweden has witnessed a growing number of scandals involving unethical behavior on the part of its corporate sector. Corruption has gained the attention of authorities, legislators and the public - putting the private sector under pressure to take action to prevent such corporate misconduct. As a result, companies increasingly prioritize strategies and policies aiming to prevent corruption. This study aims to contribute to the understanding of the role of leadership in such preventive work.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.
