Magasin för lagring av vatten och växtnäring

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Metodik för bestämning av åkerdikens status : fallstudie av ett dike i Munktorps socken

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Hur min dyslexi påverkar mitt författarskap

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald

Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.

Perspektiv på genusidentitet i förhistorien : Så resonerar forskarna

This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations.  The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.

Det vikingatida bågskyttet i Birka : Ett exempel på en framstående stridskonst med främmande inslag

This paper deals with archery in the Viking Age settlement of Birka and in particular the presence of Euro Asiatic, steppe nomadic archery equipment at the Birka Garrison and one Birka grave. The equipment contains for example closed quivers and a bow case. This paper also contains a discussion of archery battle techniques and tactics in Viking Age Birka and the implications of the above mentioned equipment to this discussion. The analysis insinuates the importance and status of archery in 10th century Birka..

Den strävsamma bonden och andra berättelser. En diskursiv studie av ska?nska hembygdsfo?reningars historiebruk.

The subject for this thesis is to examine the portrayal of the local farmer in four different museums in Scania. The purpose is to examine these two questions: 1. Which narrative and museal strategies are used in the portrayal of the local farmer by the local history societies? 2. How do the actors of the local societies relate to the living conditions and hierarchies of the rural society of Scania? The source material consists of guided tours and text material from the museums. The theoretical fields consists of history culture, use of history, historical narrative, museology and rural science act as our theoretical fields. Peter Aronsson, Anna Eskilsson and Maria Bjo?rkroth act as our main theoretical framework. Our research presents two central discourses in the portrayal of the local farmer.

Bronssvärd på Gotland : en typologi och genusdiskussion

On the island of Gotland in the Baltic sea there have been 18 archaeological find of bronze swords and five finds of bronze miniature swords and they have been dated to the bronze age periods II-VI. They have been found as ritual hoard offerings, as treasure hoards and in graves. These finds will be put in relation to each other and the bronze age landscape they have been found in. The purpose of this is to see if there is a pattern to be seen, if a specific sword-type can be found in a grave or hoard or if there?s a pattern to be seen in there placement in the landscape relating to other bronze age sites.

Selånger deltapark : Sundsvalls nya stadspark - en vision

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.

Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields

The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.

Trattbägarkeramiken och dess ritualer : En studie av keramikhanteringen vid megalitgravar i Sydskandinavien under neolitikum

This essay studies the funnel-beaker ceramic in connection with the megalith graves in South Scandinavia. In my work I have described the nature of ceramics and looked on the crockery types and ornamentation and then discussed the use of the material in a ritual perspective. In the first part I have focused on the critical aspects you have to think about when you do a study like this one. In the second part of this essay I have done a case study, with the ceramic material, in three passages graves in the area of Falbygden, Western Sweden and studied the ceramic material and the nature of it in South Scandinavia as well. Then in the third I discussed the potential use, there is two, of the ceramic material in general of South Scandinavia and looked at it in a ritual perspective..
