Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until Migration. The juveniles fledged at the end of July and beginning of August and initiated Migration during October and beginning of November. The length of the post-fledging period, until Migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Jag har valt att skriva om Migrationen i USA mellan 1900 och 1950, detta eftersom dessa årtal var då Migrationen var som störst och den har också gått till historien som bokstavligt talat just en folkrörelse.Det har pågått en jämn ström av in- och utflyttning från södern men jag tänker fokusera på den Migration som skedde mellan 1900 och 1950.Det som är intressant med Migrationen är att den förändrade hela USA genom att den visade att svarta kunde förändra genom att förflytta sig eftersom man därigenom började ändra infrastruktuen och maktbalansen..

Uppsatsens syfte är att, med hjälp av postkolonial teori belysa matens roll i några personers Migration till Sverige. Nio stycken informanter har berättat om sina erfarenheter och minnen av hemlandets mat och maten i Sverige och på olika sätt diskuterat sin personliga och kollektiva utveckling ur ett matperspektiv. Resultatet visar att mat spelar en viktig roll för gemenskaps- och tillhörighetskänslan i sociala situationer samt att informanterna ibland upplever att de hamnar mellan två kulturella gemenskaper, ett slags ?third space? med möjlighet att föra dessa närmare varandra med hjälp av hybridisering. Mat blir då ett konkret sätt att både se och upptäcka den utvecklingen men också någonting att bygga nya gemenskaper runt..

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

There is an irregularity in the interregional Migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the Migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to otherMigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

This paper deals with archaeological prospection of an Iron Age farm site in Toland, Fresta parish, Uppland County in Sweden. The purpose of the paper has been to see whether the geophysical methods applied (GPR & EM-38) could produce useful results that could motivate its use in similar surveys in the future. Geochemistry has been used for the purpose of identifying possible activity areas on the site. The results have shown that it is possible with a GPR survey to identify postholes originating from the Migration Period longhouse at the site. The combining of several methods have been important for the identification and interpretation of several areas of interest..

An comparativa study of the Social Democrats and theModerates parties programme 1990-2013.?The purpose with the essay is to examine if the Social Democrats and the Moderates havegotten closer within labor market policies, education policies and also within the view ofMigration and integration.

I denna studie undersöks unga svenskars erfarenheter av temporär Migration till Oslo, Norge. Syftet med studien var att öka förståelsen för ungas temporära arbetsMigration; både beslutsprocessen inför eMigrationen, och vad som påverkar vistelsens varaktighet. Detta har undersökts genom djupintervjuer med sex respondenter som alla har gemensamt att de är från Västerbotten, har bott i Oslo, och sedan flyttat tillbaka till Sverige. Intervjuerna analyserades därefter med hjälp av en kvalitativ innehållsanalys.Resultatet visar att en av de viktigaste aspekterna i beslutsprocessen var respondenternas önskan om att tjäna pengar för att kunna resa. Migration kan därmed ses som ett medel för att förverkliga sina resedrömmar.

During the Migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting Migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, Migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

The following essay examines the conditions of whether a child perspective is recognised in the second authority of the new Swedish asylum process, the Migration Court of Law and inquire into the viewpoint of these decision makers as to what a child perspective in this context represents.The method used was a qualitative study that contained interviews with eight respondents, divided into four judges and four jurors. The material gained from the respondents was then analysed by using theories regarding a child perspective and theories that deal with interpretation of a text, ethics and court sociology.A few conditions of whether a child perspective is recognised has been revealed and we also found that the child perspective in theory is a wide perspective, that includes many aspects of how a child is recognised. In practice, however, the child perspective can be divided into two separate perspectives where one of them involves an adults view of a child?s perspective, and the other involves the perspective of a child, the child?s own view of its existence and perceived reality..

This thesis discusses the theory of securitization in relation to the issue of irregularMigration, from EU level to national level. By using discourse analysis, the purpose isto explore whether the discourse leads to practice when it comes to nationalimplementation of EU debates on return policy. The material used in this workconsists of policy documents regarding the Return Directive from the EuropeanCommission as well as the Reva Project in Swedish Migration policy. The mainobjective of the Reva Project is to make the process of returning irregular immigrantsmore effective and it has been strongly criticized, both by media and public opinion.The conclusion of this case study is that even if the security rhetoric may appearstronger on the EU level, the main elements of the security discourse are stillportrayed in the implementation on the national level. Based on this analysis we canmake the presumption that discourse develops into practice in the case of returnpolicy in the EU-member state relation..

Due to exploitation of the world?s rivers, the upstream Migration of anadromous species is frequently delayed or even prevented. To mitigate these problems and allow fish to migrate past obstacles, structures such as fish ladders have been developed. However, recent studies show that many of the present fish passage facilities are deficient. Monitoring and evaluation of passage facilities is therefore crucial to enable necessary adjustments.

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream Migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning Migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream Migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
