Antalet tillgängliga IPv4-adresser håller i dagsläget på att ta slut och det ärdärför nödvändigt att hitta en metod för att migrera nätverket till den nyastandarden, IPv6. En migrering kan kräva att de två IP-versionerna måsteanvändas i nätverket simultant, för att de system som är beroende av nätverketska vara tillgängliga. Syftet med arbetet var att undersöka prestandani de olika migreringsteknikerna, samt att få fram vilka tekniker som är attföredra. Med hjälp av två scenarion, uppsatta i labbmiljö, testades migreringsteknikernasprestanda med verktyget Iperf. 6to4 och GRE testades iden ena miljön samt NAT64 och Teredo i den andra miljön.

The EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Syftet med vår uppsats har varit att undersöka anhöriga till missbrukares upplevelser av stöd och stödinsatser. Studien baseras på kvalitativa intervjuer med fem personer som alla har erfarenheter av att ha levt tillsammans med en person med alkohol- eller narkotikamissbruk. För att förstå våra informanters vardagsverklighet har vi analyserat resultatet utifrån symbolisk interaktionism som är ett perspektiv som syftar till att beskriva en social verklighet med fokus på samspelsprocesser. I vårt resultat har det framkommit att de anhöriga har påverkats och formats på många olika sätt av livet tillsammans med den med missbruksproblematiken. Ett återkommande och centralt begrepp i vårt resultat är begreppet skam som är en stark emotion som har påverkat våra informanter i deras vardagsverkligheter.

This report is the result of a project work carried out at Karlstad University in conjunctionwith the local consulting firm Camatec where most of the work has been performed.The work can be classified as a classic engineering work with supportive theories andcalculations which in this context is relevant.The engineering project has focused on developing new standards for a conveyor that is usedin the Värmland paper industry where large rolls of paper are produced. A conveyor can takeits appearance in many different forms but in this thesis it has been an exemplary look and ithas also become modulatable with a central section, a drive end and a turning end.The construction work has been build under CAD programs such as Pro Engineer, drawingshave been created and costings have been analyzed. Strength calculations have been made andcooperation from several different companies have erected to explore different solutions andideas for a modern and sustainable conveyor..

Mångfald och mångkulturella förhållanden nämns av Integrationsverket som viktiga inslag i det svenska samhället och man arbetar därför inom verket för att motverka etnisk diskriminering och rasism. Enligt Integrationsverket handlar frågan om etnisk mångfald ytterst om samhällets förmåga att leva upp till principen om allas lika värde oavsett etnisk, kulturell eller religiös bakgrund. Integrationsverket har en avgörande roll för integrationen i Sverige och centralt i verkets arbete är den etniska mångfalden och integrationen av utlandsfödda invånare. Nya invånare, som beviljats uppehållstillstånd, tilldelas av Integrationsverket en bok, ?Sverige ? en pocketguide?, med syfte att underlätta den första tiden i Sverige.

The topic of this thesis is immigration policy in the European Union with focus on the Schengen cooperation and illegal immigration. Immigration policies and other policy areas such as asylum and refugee policies have become hot topics on the EU agenda in recent years. Partly because of cooperations like Schengen, but also because a need of a common immigration and asylum policy has emerged.The purpose of the thesis is to give a better understanding of the relations that might be found between illegal immigration to the EU and the Schengen cooperation. Schengen plays an important role in dealing with international migration in the EU and will probably continue to do so in the future.The thesis is a comparative case study with Spain and Germany as the two specific cases. Their national immigration policies are examined and put in relation to the Schengen cooperation.

This essay focuses on how trafficking is defined and dealt with in recent European policies,and particularly how prostitution take part of these discursive developments. Treaties andagreements on trafficking in human beings and for sexual exploitation have been made bythe European Union and United Nations amongst others, which have been signed andratified by the EU countries in Action Plans. In this essay, five national Actions Plans, fromAustria, Great Britain, Poland, Spain and Sweden between 2007 and 2009, have beencompared in order to see similarities and differences in how the phenomenon of traffickingis done through language. Based on Discourse theory and focus on discursive struggles, theresult show a hegemony around trafficking as a social issue in the Action Plans studied,exploiting humans, mainly children and women, sexually, but also how trafficking is framedas a problem of the nation state and the domestic labour market. It is also illustrated howdifferent meanings of prostitution make the trafficking discourse antagonistic and contested.Finally, the essay discusses the trafficking discourse in relation to EU strivings towardsharmonisation and power imbalances of migration and economy in Europe..

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..

Uppsatsen är ett examensarbete på 15 hp inom produktdesignprogrammet på Malmö högskola. Projektet hanterar blöjors utformning med ett resulterande förslag på hur denna produkt kan förbättras, med en fördjupning inom hållbar utveckling. Resultatet blev en blöja med inlägg, för den mer omedvetna konsumenten, som minskar antalet byten och därmed mängden miljöpåfrestande material som behöver tillverkas och slängas I fördjupningen intervjuades Olof Kolte, framträdande industridesigner som verkar inom hållbar utveckling, och en litteratursökning på området utfördes. Förundersökningen angående blöjor baserades främst på kvalitativa intervjuer, och konceptualiseringen baserades främst på ett antal brainstorms och en metod som kallas bakåtmetoden, utvecklad av Edward de Bono, författare och konsult inom lateralt tänkande..

De mänskliga rättigheterna brister i sin universalism. Många människor som lever i demokratier nekas grundläggande rättigheter därför att de inte är medborgare i den stat där de bor. Anledningen till detta är att nationalstater, som har ansvar för att de mänskliga rättigheterna efterföljs, traditionellt endast anses ha ansvar för sina medborgare. Uppsatsen utreder och synliggör motsättningen mellan mänskliga rättigheters inkluderande och medborgerliga rättigheters exkluderande natur samt vilka konsekvenser detta får för icke-medborgare.Tre teorier om postnationellt medborgarskap presenteras och genom en mer utförlig diskussion av dessa idéer försöker vi i en konstruktiv ansats utforma en mer inkluderande medborgarskapsmodell i två nivåer; den globala och den nationella. I denna modell utgör de mänskliga rättigheterna en juridisk grund för ett medborgarskap för de människor som saknar det nationella.

Följande studie genomfördes för att undersöka koncentrationsförmågan hos 15-årigafotbollsspelare. 15-åriga barn kan uppleva stora skillnader i prestation inom sin idrott ochstudien utfördes för att försöka identifiera ålderseffekter och ifall dessa är orsaken till varförvissa fotbollsspelare är bättre på att koncentrera sig än andra. Relativ ålderseffekt menar attbarn som är födda tidigt på året ofta presterar bättre inom sin idrott än barn i samma ålder somär födda sent på året (Baker, Schorer, & Cobley, 2010).Totalt undersöktes 207 fotbollsspelande 15-åringar, av dessa var n= 78 flickor och n= 129pojkar. Dessa individer fick svara på en enkät, TAIS ? Test of Attentional and InterpersonalStyle (Nideffer, 1976) angående deras koncentrationsförmåga som sedan analyserades medhjälp av ett envägs ANOVA och Chi2test.Föreliggande studie visade inget samband mellan spelarnas koncentration och derasidrottsliga nivå.

Sustainable development has become more and more important over the past years. The term Corporate Social Responsibility (CSR) is closely connected to sustainable development and focuses on organizations responsibility towards the society and the environment in which it exists. Companies within the mining industry were among the first to initiate CSR-work due to the fact that they have a great impact at the local community, both socially and environmentally. Today they are still in the forefront of the development of CSR-questions in general, and community involvement and development in particular. Earlier studies made on this area have focused on the strategic level of community involvement and development.
