Reingsresultat, drifterfarenheter och kostnadseffektivitet i svenska våtmarker för spillvattenrening

I denna studie har funktionen hos sju anlagda våtmarker för behandling av avloppsvatten i Sverige jämförts över tid med avseende på avskiljning av kväve, fosfor och BOD. Syftet var att undersöka våtmarkernas långsiktiga funktion, skötselåtgärder och relaterade kostnader. Våtmarkerna (1,6 - 28 ha stora) har varit i drift olika länge, mellan 7 och 17 år, och befintliga övervakningsdata samt intervjuer med ansvariga för respektive våtmark användes som grund för studien. Resultaten visade att våtmarkernas reningsfunktion generellt sett varit god utan någon tendens till en försämrad funktion över tid. Våtmarkerna belastades med 1100 - 9900 kg N/ (ha·år) och avskiljde mellan 420 och 2400 kg N/ (ha·år), beräknat som ett medelvärde per anläggning.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Vegetationsförändringar i Hornborgasjöns naturreservat : med fokus på restaureringems följder

Den här studien undersöker hur vegetationen förändras mellan 1979 och 2010 i området som idag är Hornborgasjöns naturreservat. Sjösänkningar i området ledde till att ett igenväxt träskområde ersatte en viktig vattenreservoar och närsaltfälla. Restaureringsarbetet under 80-talet var banbrytande och antagligen ett av vår tids mest omfattande naturvårdsarbete. Studien svarar också på om restaureringen uppnådde sitt mål och om resultatet blev som man tänkt sig.I arbetet skapades en aktuell vegetationskarta för 2010, denna jämfördes med en i arbetet digitaliserad vegetationskarta från 1979. Kartbilder skapades och justerades i ArcGIS och vegetationsytornas area framtogs för att möjliggöra en vegetationsanalys mellan kartorna.

De Nordeuropeiska långhögarna : Hus för de döda

The discovery and excavation of Long Barrows has been one of the major developments in the understanding of the Early Neolithic in Southern Scandinavia during the last decade. The Long Barrows are one of the oldest monumental burial forms that we see in northern Europe in the neolithic. They are also the first example of a common idea that is connected to a monumental burial form amongst the people. In this essay I attempt to show that there actually are quite a large number of Long Barrows in Scandinavia that show similarities with Long Barrows in well-known areas such as Kujavia (Poland) and Pommerania (Germany/Poland), in both architecture and location in the landscape. I also scrutinise some theories regarding this phenomenon and discuss, and i some cases, criticise them.

Bergen som vakar ?ver de d?da. En bebyggelsearkeologisk studie av tre fornborgar i Torslanda och Bj?rlanda

The hillforts of Bohusl?n are numerous, yet few have been studied, leaving gaps in our understanding of their dating, morphology, and connections to nearby prehistoric sites. With the help of settlement archaeology, the aim of this study has been to analyse three hillforts on Hisingen and answer these questions. This was done by observing the location and morphology of the hillforts and by analysing the age and functions of nearby prehistoric sites within a kilometer of the hillforts. The results indicate that Bj?rlanda 22:1 and Torslanda 56:1 were likely ritualistic enclosures, while Torslanda 15:1 had defensive functions.

CAMPUS BTH : ett gestaltningsförslag och en studie av begreppet campus

This text answers the questions how do we define what a campus is, how the concept of the campus came to exist and how it is used today, and how the Blekinge Institute of Technology (BTH) campus can be designed according to site conditions and the conclusions drawn from case studies at Chalmers University of Technology and Karlstad University. The purpose of the case studies is to gain insight into their campuses advantages and disadvantages. This finally results in an interpretation of how the Blekinge Institute of Technology campus can be planned. A campus is the area of land on which a college or university and its surrounding buildings resides on. Campus as a concept meant a field at first, it later evolved at American universities due to their design of college campuses.

Studenters uppfattningar om stödet från högskolebiblioteken vid studieformen Problembaserat lärande i distansstudier

The purpose of this thesis is to investigate how students who study with Problem-based learning PBL in a distance learning course perceive the support from the university library. I first went into adult education, PBL and distance studies, one at a time, and then took a look at the combination of problem-based learning in distance studies. During the investigation, I conducted five interviews using a phenomenographic method to understand how the students perceived the support they received from the university library. The university library gives a lot of support but what I noticed while I was writing was that it is difficult to reach the students with the information regarding the help that is available to them. I give some example on how to develop the support and find that the students have a wide range of different needs for support from the library depending on their individual situation, social context, academic ability, location and course of study.

Stenebergs sockerbruk: en fallstudie av en timmerstomme fr?n 1739

Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in 1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood. Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there exists today a surprisingly low amount of documentation of the building itself. In order to enhance the existing and lacking building documentation, this case study aims to shed light on the building's log-timber built frame, focusing on how it was constructed, how the long lengths of its walls were handled and what type of joinery and tools were used. A thorough investigation of the building is conducted on site, followed by gathering of information which is then presented through text and illustrations. The findings indicate the orientation of timbers, location of joints and scarfs as well as tool marks which together contribute to the forming of a basis of understanding of the building's construction..

Bortom graven : En rumslig studie av Tjustbygdens rösen

Bronze Age cairns have been interpreted as everything from navigation marks to marking liminal places in the landscape. It has also been stated that the main purpose of their location is to be visible. This is something that has been taken for granted. The main problem is the cairns have been considered as a homogenous monument. With the help of digital methods like GIS it is possible to test this kind of questions in quantitative way.

Halshuggna vs. Magbegravda : En undersökning mellan halshuggna personer och magplacerade personer under järnåldern i Sverige och Danmark.

Decapitated Vs. Stomach buried ? A study of decapitated people and stomach placed people in Iron Age in Sweden and Denmark. This essay is about decapitated persons in graves and those buried on their stomach in the Iron Age in Sweden and Denmark. The analysis is to compare these graves by six perspectives; location of the grave, construction of the grave, grave goods, sex, age and interpretations of the grave.

Hör upp!!

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..

Biblioteksanvändning på institutionen folkbibliotek : sedd genom en användarundersökning vid Alingsås huvudbibliotek

This paper deals with how people use public libraries. An attempt is made to distinguishbetween different user groups on the basis of how they use the library. The roles of thelibrary in relation to its users are also discussed.The paper is based on a user study with the cooperation of 195 users. The user studywas carried out at the Public Library of Alingsås 1994. As material for comparisonsimilar studies from Sweden, but even from Denmark, have been used.

Att leta efter kännskap : Hur lärare ser på utemiljön som en miljö för lärande

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

Hur värderar människor utemiljön och dess funktioner? : två fallstudier - Tarapoto, Peru, och Uppsala, Sverige

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

Eldsjälar, svartfötter och byråkrater : En undersökning av konflikten kring Tensta Konsthall

The purpose of this essay was to overview the conflicts regarding the exhibition space (Kunsthalle) Tensta Konsthall during 2003 and 2004, in order to gain an understanding of the following: why the conflict started, if anyone exceeded their authority, how the case has been reviewed in the press, what kind of value judgements lay behind the actions and why this case has received so much attention. By studying mainly press material and political documents it has been made clear that Tensta Konsthall?s location in an ill reputed suburb of Stockholm has been the cause for its exposure to different demands and expectations compared to other similar exhibition spaces. Further the essay deals with questions raised by the conflict in the intersection of culture and politics..
