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).
Moderbolagets ansvar för dotterbolagets skulder : Avseende stödbrev och ansvarsgenombrott
Stödbrev utfärdas av ett moderbolag till en koncernextern part då ett avtal skall slutas mellan stödbrevsutfärdarens dotterbolag och stödbrevsmottagaren. Uppsatsen redogör för hur stödbrev fungerar och dess uppbyggnad. Det undersöks också vad det är för bakomliggande mekanism som förklarar hur avtal kommer till stånd och vilken betydelse det får att gemensam partsvilja mellan utfärdare och mottagare inte finns om stödbrevets rättsliga innebörd. Eventuellt kan Grönfors modell om avtalsgrundande rättsfakta vara en förklaring på avtalsverkningarna. Uppsatsen undersöker också institutet ansvarsgenombrott.
Närståendes upplevelser av sjuksköterskans stöd i samband med plötsligt dödsfall : En litteraturbaserad studie grundad på analys av kvalitativ forskning
Background: In Sweden about 19000 people fall victims of sudden death every year. This covers around 20% of all deaths. Relatives are those who are closest to the patient, regardless of the type of relationship. When a patient suddenly dies this affects the relatives and they can suffer from high risk of complicated grief reactions or crises. Being the nearest professional contact in these situations, the nurse has an important role in supporting and guiding the relatives.Aim: The aim of this literature review was to nominate the relatives' needs of support from the nurse when a loved person suddenly dies.Method: The literature review was based on seven articles with a quality approach.Results:The analysis resulted in four themes; "to be seen and confirmed", "information", "take farewell" and "follow-up ".To be able to give support both mentally and physically, it is important for the nurse to give proper attention to the relatives.
Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Hedgefonder : Hur kan dess risker och möjligheter förmedlas
We have in this essay studied the Swedish Hedge Fund Market available for the average Swedish private investor. We have closely looked at the risk measurements that are applicable on the evaluation of Hedge Funds today, and furthermore studied how they are communicated and what they actually contribute with in terms of risk and yield. Our survey attempts to clarify the shortcomings in the communication between the Hedge Fund Managers and their smaller investors. Do they really know where they put their money? The market is rapidly expanding and our goal was to find improved ways to inform about the Hedge Funds risks and opportunities.
Kan företag genom sin redovisningsinformation påverka volatiliteten i aktiekursen?: en studie av sambandet mellan informationskvalitet och risk
The purpose of this paper was to examine the potential presence of a relationship between the quality of corporate financial disclosure and the volatility in stock price in the Swedish market. This was carried out by investigating the hypothesis that an accurate annual report with high information quality results in a decrease in volatility. Previous studies have been done with this approach and in some cases the above stated hypothesis was found to be true. Thus, in the absence of a perfect efficient market the level of information quality may to some extent explain the volatility in stock price. However, the result of our study gave no evidence in support of this hypothesis.
Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen
The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige
In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable
concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population
consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas.
Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.
Clostridium difficile toxins in meat-producing guinea pigs in the highlands of Peru
The guinea pig is an important meat-producing animal in Peru as well as in several other South American countries. They are held in different kinds of systems, from the small backyard breeders with few animals to the large commercial farms with thousands of guinea pigs. One of the major issues at the farms is animals dying of unknown causes. Salmonellosis is often considered as a major cause, but samples for confirmation are rarely taken. It has been known for a long time that Clostridium difficile (C.

En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Riskbedömningsmodeller. Kan användandet minska frekvensen av postoperativt illamående och kräkning?
Inledning Postoperativt illamående och kräkning är ett välkänt problem efter sövning medgenerell anestesi och drabbar mellan 20 % och 30 % av alla patienter som blir sövda. För attminska de obehag och lidande som illamående och kräkning kan ge den postoperativapatienten vore det optimala att profylaktiskt behandla de patienter som löper en stor risk attdrabbas av postoperativt illamående och kräkning. För att avgöra hur hög risk patienten har attdrabbas av postoperativt illamående och kräkning beskrivs i litteraturen ett flertalriskbedömningsmodeller som sjuksköterskan kan använda sig av. Syfte att granska omanvändandet av en riskbedömningsmodell kan minska frekvensen av postoperativt illamåendeoch kräkning hos patienter som erhållit generell anestesi. Metod Litteraturstudie.
