Skred är en sluttningsprocess som orsakar stora materiella skador och som dödar många människor, runt om i världen. Med de svenska markförhållanden förekommer skred främst i lera, lågväxt vegetation och i sluttningar som överstiger 5.71 graders lutning. Syftet med denna studie är att ge en övergripande bild över skredproblematiken i Köpings kommun. Metoder som har använts är litteraturstudier, rumslig analys med geografiska informationssystem (GIS) och intervju med Köpings kommuns gatu- och parkchef.I Köpings kommun har det tidigare förekommit små skred som gett upphov till mindre omfattande konsekvenser. Det är sannolikt att skred kommer att inträffa vid slänter mot vattendrag i Köping och Kolsva.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Kantzoner mot vattendrag är av stor betydelse för att upprätthålla eller förbättra vattenkvaliteten i våra vattendrag. De strandnära zonerna fungerar som reservat i skogen med stor biologisk mångfald. De utgör barriärer för näringsämnen, löst organiskt kol, sediment, kvicksilver och andra miljögifter. Trädens rötter armerar jorden närmast vattendraget och minskar Erosion och sedimentation. Syftet med detta arbete har varit att beskriva varför kantzoner bör användas och hur bredden på kantzonen, med hjälp av en modell i ArcMap, kan anpassas efter förhållandena runt vattendraget.

Large amounts of phosphorus (P) are lost from the arable land due to water Erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the Erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land Erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Purpose: This study`s purpose is to investigate the role of a business incubator in the strategic decision situations during the process of a new venture startup. It also aims to explore the methods and instruments the incubator and its advisers applies during the process.Methodology: This study is built on the basis of a hermeneutic approach with qualitative method and abductive design. The empirical material collected consist of interviews from two case studies and secondary data collection from different related sources.Theoretical perspective: The theory in the study consists of the elements of previous research on innovation processes and entrepreneurship. To analyze the data, models and theories related to decision making, incubation, process theories and organizational theories.Empirical foundation: The empirical material consists of interviews and data from two completed case studies. Additionally consist a relatively large part of the empirical data out of a comprehensive information retrieval from various secondary sources such as internet, newsletters and annual reports.Conclusion: The assay was able to detect not just one, but a variety of roles that the incubator occupies at different stages of the innovation process.

The aim of this paper is exploring questions regarding the problem of absenteeism among high-school students in Sweden. Fifteen students attending an urban high-school have been interviewed about their views and experiences of absenteeism. The author analyzes the students? answers by taking into account two different sociological approaches which give two different explanations about the way young people experience and estimate education. The French sociologist Bourdieu theorized that differences in cultural capital influence the permanent internalization of patterns of thought and behavior.

Syftet med detta examensarbete är att belysa de otydligheter i förfrågningsunderlag och bygghandlingar som Skanska har stött på i samband med kalkylering/utförande av dammrenoveringsprojekt i Norrland. De aktuella projekten är inom ramen för det dammsäkerhetshöjande åtgärdsprogram som Vattenfall driver mellan 2002 och 2007. Otydligheterna har mest kretsat kring den bristande beskrivning av hur Erosionsskydden på kraftverkdammarnas uppströmsslänter ska utföras. Eftersom otydligheterna hitintills lösts på plats har Skanska även velat öka sina kunskaper om hur Erosionsskydd kan utföras. Bakgrunden till Vattenfalls dammsäkerhetshöjande åtgärder grundar sig i flödeskommitténs riktlinjer för dimensionerande flöden och deras beslut att tillämpa RIDAS, vilket leder till att en del av deras anläggningar inte uppfyller de nya föreskrifterna.

This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material.

The purpose of this essay is to examine and compare the news covering of Swedens three biggest cities (the metropolitan areas) and their surrounding areas with the covering of the rest of the country (the provincial areas) in two daily national newspapers, Aftonbladet and Dagens Nyheter. The aim has been to answer the following questions:- What amount of the news coverage in Aftonbladet and Dagens Nyheter concern the metropolitan areas compared to the provincial areas, and how do these two newspapers differ in the news covering of these areas?- Is there a difference in the news articles size and content, depending on weather they concern the metropolitan or the provincial areas?- How has the balance between news concerning metropolitan and provincial areas changed over the recent 20 years?The theories used in this study are News values, the media commercialization and Popular Journalism, and The Agenda Setting Theory. The method that has been used is a Quantitative Content Analysis.Despite the essays hypothesis, that the news coverage in the two newspapers would be dominated by material from the metropolitan areas, the result showed that a majority of the examined articles concern the provincial areas. It also showed that Aftonbladet has a bigger percentage of provincial news than Dagens Nyheter.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil Erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark Erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Många faktorer påverkar den orala hälsan, däribland kosten. Idag finns många olika kosttyper samt livsstilar, och något som ökar i Sverige är den vegetariska kosthållningen.
