Hav och Strand : stenteknologi och marin anpassning på Gotland under Senboreal/Tidigatlantisk tid
The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..
Underlag för BREEAM-certifiering : Kristianstad Nya Galleria
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Att fly sin kropp. En studie om gränsöverskridning i Sara Stridsbergs prosa
Sara Stridsberg?s novels Happy Sally, Drömfakulteten and Darling River are all brimming withliterary images of movement and becoming. The physical aspects of being a female subject inbecoming highlights the enfleshed body as important. Themes such as sexuality, power andviolence can be traced in the beautiful but most disturbing narratives of Stridsberg.The purpose of this study is to show the reader how the literary female characters aretranscending the physical borders of their bodies in order to become something more than what thehuman form allows them to be. Heteronormative sexuality, sickness, closeness to water andanimaling are bound together by the way they enact the female characters to stretch beyond thesurfaces of their skins.
Varg i Sverige
Vargen har varit hatad i alla tider, en symbol för något ont. Den jagar gärna i flock och tar renar och river får. I den här artikelserien undersöks orsaken bakom licensjakten på varg 2010, det vill säga bristen på acceptans, och om det är ett argument för att skjuta 10 procent av vargstammen som idag anses vara akut hotad. Artikelserien ger också svar på varför en vargpopulation som är så inavlad som vår inte kommer klara sig långsiktigt, och vad som krävs för att få en hållbar stam..

Utvärdering av rörelsemönster hos öring (Salmo trutta) utifrån otolitmikrokemi
The classic view of trout (Salmo trutta) life history is that trout begins its life in freshwater, migrates to the ocean after about 1-4 years and then returns to freshwater to spawn. As trout fry have been caught at the mouth of the River Emån, near the Baltic Sea, researchers have speculated that some trout emigrate during their first year of life. The purpose of this study was to describe the variation in the length of time trout reside in freshwater before they migrate to the ocean for the first time. Another purpose was to investigate whether it was possible to discern where and how long the fish spent in freshwater and saltwater during different parts of their lives. Between 2007 and 2009, 23 adult trout were captured in the River Emån in southeastern Sweden.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Störs laxens lekvandring i en kraftverkspåverkad älvsträcka? :
The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence
area between the power-station outlet and the bypass-channel in river Umeälven (flow 430
m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes.
In 2004 the water flow in the bypass-channel was altered during the day with increased
flows during the nights while the water flow in 2005 mainly was altered between the
weekdays and weekends. Salmon showed altered migratory behaviour in this confluence
area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses
depending on flow-changes in both the bypass and the power station outlet. Increased
turbine flow through the power-station generally attracted salmon into the tunnel outlet area
while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the
confluence area showed an increased swimming activity up- and downstream due to time in
the day and flow-rates through the tunnel outlet. No changes in activity could be detected
due to increasing or decreasing flow through the hydro-power facility.

Passage efficiency and migration behavior for adult Atlantic salmon at a Half-Ice Harbor fish ladder
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.
Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen
During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.
GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :
Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments.
Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.
Hemingways kvinnor : stereotypa eller en spegling av sin tid?
This essay is about the female characters in the books of Hemingway. Are they as simple as some critics say, or are they more complex beings, and which ones of the women in the life of Hemingway, can be noticed in his female characters? In the work with this essay, biographies of Hemingway as well as a few of his novels have been studied. The selected novels are Farewell to Arms, Across the River and into the Trees, The Sun also rises and the short story The Snows of Kilimanjaro. The selection was based on the fact that these stories contain good female characters.
Whispers in the forest : a field study about communication within Vi-agroforestry
The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data.
I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003)
Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.
