Restaurering av vattendrag :

SAMMANFATTNING Rinnande vatten har över en lång tid spelat en väsentlig roll för landskapets geomorfologiska processer och utgör viktiga livsmiljöer för djur och växtsamhällen. Vattendrag har bidragit till människans utveckling och välstånd. Sedan urminnes tider har vattendrags miljöer nyttjats som boplats, för vinning av energi, transport och fiske. Likt allt liv på vår planet är människan beroende av vatten. Betydelsen av vattendragen, som del av den hydrologiska cykeln, kan därför inte betonas nog. Genom mänsklig aktivitet har dock rinnande vattens egenskaper och landskapsbilden som helhet i många områden förändrats drastiskt.

Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Angel Thesis : En spel produktion

Detta projekt har varit ett som har haft både sina höga och låga punkter. Vi påbörjade detta projektet med viljan att skapa ett spel som var vårt, som representerade oss och som vi vill spela. Vad vi slutligen bestämde oss att göra var ett spel som fokuserade på story och spel-känsla som hade en mystisk stämning och sin egen stil. Detta tillsammans med ett par bra koncept och idéer så påbörjade vi att arbeta på Angel Thesis, ett action RPG. Vi har under projektets gång stött på många svårigheter, något som om och igen testat gruppens moral.

S:t Göransområdet : gestaltningsprogram för ett stadsutvecklingsområde på nordvästra Kungsholmen i Stockholm

North Western Kungsholmen in Stockholm is confronting big changes and Stockholmsstad is planning that the area will be an extended part of the existing structure in centralStockholm. Dwellings and offi ces are built and the population increase heavily. Th isresult in a need to look at how public green areas can develop and be designed. Th epurpose is to design a proposal for a master plan of S:t Göranområdets public greenareas. Exploateringskontoret, Stockholm stad, who has initialized the task, claim thatthere is a need of clarifying and shield the qualities in the green areas of today and howto create new green structure.The problem formulations which are current in this master thesis are:? Is there a need of a distinct identity for the green areas of S:t Göransområdet? If so,how is this created?? How can the green parks and nature areas inside S:t Göransområdet be improved anddevelop?? How can the connections between the green areas inside S:t Göransområdet beclarifi ed and how can they connect to the surroundings?To get inspiration and information for the design this thesis include a study of theincluding parts in the design process.

Luft/luftvärmepump : - Med möjlighet till återvinning

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

Felbegreppets tillämpning på skogsplantor

Uppsatsen behandlar felbegreppets tillämpning på skogsplantor. Lagstiftningen inom området skog och skogsplantor är relativt omfattande men skogsplantor är biologiska produkter varför lagstiftning inte helt kan förhindra att skador eller sjukdomar ändå uppstår. Det är helt enkelt inte möjligt att framställa skogplantor utan att en viss andel av dem är behäftade med fel. Då det är en mängd sammanverkande faktorer som kan bidra till skador eller plantors död kan det vara svårt att fastställa om orsaken till skadan/plantdöden var att hänföra till plantorna eller faktorer i uppväxtmiljön. Svårigheter att fastställa orsaken kommer därför bidra till svårigheter för skogsägarna i samband med reklamation.

Naturvärdesbedömning av naturreservatet Blänkabacken, i Örebro kommun : Inventering av signalarter med fokus på mossor och lavar som indikerar höga naturvärden i skogsmiljöer.

I dag råder det brist på död ved i Sveriges skogar. Detta på grund av det intensiva skogsbruket där man kalhugger och plockar bort all liggande ved. Dock är det viktigt med många döda träd i olika nedbrytningsstadier för många skogslevande arter. Svenska skogar har få urskogar där naturliga avdödningsprocesser av träd får ske och därför minskar den biologiska mångfalden i skogen. Tre arter som endast trivs i naturskog är tickorna ullticka, Phellinus ferrugineofuscus, gränsticka, Phellinus nigrolimitatus och vedticka, Phellinus viticola.

Förändring av radiocesiumtillståndet i jordbruksgrödor i Gävleborgs, Västmanlands och Uppsala län efter Tjernobylolyckan samt en fallstudie med stallbalansberäkningar på en mjölkgård :

Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.

Utbrändhet och Copingstrategier hos Sjuksköterskor och Distriktsköterskor inom Hemsjukvården

Att arbeta som sjuksköterska/distriktssköterska (SSK/DSK) innebär arbetsuppgifter som varierar mycket. Denna arbetsmiljö kan vara väldigt krävande och kan påverka SSK/DSK på ett negativt sätt vilket kan leda till fysisk och psykisk påverkan. Copingstrategier är hur personer hanterar krävande situationer, utan effektiva copingstrategier finns risk att personen drabbas av utbrändhet. Syftet med denna studie var att beskriva graden av skattad utbrändhet och vilka copingstrategier SSK/DSK använder sig av i sitt arbete inom hemsjukvården (HSV). Studien undersökte också om det fanns några skillnader gällande grad av utbrändhet och förekomst av copingstrategier beroende på vilket län SSK/DSK arbetade i samt om det fanns samband mellan copingstrategier och grad av utbrändhet hos SSK/DSK.

Metodutveckling för analys av PBDE och HBCD i sediment

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

Kentucky Inventory of Mindfulness Skills: validering av den svenska översättningen och en studie av anhöriga till borderlinepatienter.

This paper has two parts. In the first part we analyse the Swedish translation of KIMS and we compare it with the American version that Baer and colleagues developed(Baer et al, 2004). Our focus is the factor structure, internal consistency, scale correlations and validity in relation to the already validated translation of the MAAS. The second part has three issues: Does a group of relatives to persons with borderline personality disorder differ from a group of university employees with respect to different aspects of mindfulness? What are the correlations between KIMS and the symptom measure BSI-GSI for the group of relatives? Has the Family Connections program had any effect on the degree of mindfulness for the group of relatives? 123 university employees answered the KIMS questionnaire.
