During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

The aim of this study was to understand how care staff in residential care perceive and work with elderly mental health and how these perceptions and work is related to aging. We have gathered our empirical material through eight qualitative interviews and vignettes with care staff in residential care. The study was conducted in a municipality with 10 000 to 20 000 inhabitants in southern Sweden. The material was analyzed with use of ageism as a theoretical frame of reference. The results showed that the care staff had different perceptions of mental illness in general and regarding the elderly.

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

The main task of the criteria was to guide the search for the solution.

Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

The purpose of this study was to evaluate the effect of bilateral repetitive transcranial magnetic stimulation (rTMS) on language ability in eight participants with aphasia. All participants underwent two periods of treatment and five periods of evaluation. During one treatment period high frequency stimulation was given to the left hemisphere and low frequency stimulation to the right and in one other period placebo stimulation was given. Boston Naming Test and Token Test were used to assess the effects of treatment on naming ability and language comprehension. Results showed that no significant effects were found on group level.

In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..

This report addresses the growing need to adapt the medical healthcare to the new possibilities that can be accomplished by incorporating a web aspect to the personal treatment plans of patients. It describes what implementations that need to be considered in order to successfully convert to a partially web-based treatment.The report also reflects the potential economical gain that can be made by keeping the communication between the patient and the doctor frequent. It also takes into account the personal gain to the patient by increased feedback and easier ways to communicate with their attending physician and thereby increasing the quality of their healthcare and service.The construction of a prototype of the system required is also included in the report as a description of construction and functionality of the prototype along with results and estimated outcome..

Background   The patient's rights to self-determine their own health care is described in Swedish legislation and guidelines. However, due to infancy, unconsciousness, severe brain damage or certain diseases, some patients might be unable to make such decisions. Ethically difficult situations do occur, not infrequently associated with culture. Since the patient is vulnerable, there is a risk that the patient in the treatment and care can not be bothered to maintain right to autonomy and that the nurse violates patient integrity.Aim                 The aim of this study was to illustrate the nurse's dilemma when the patient refuses vital caring efforts.Method           A literature review of eight scientific articles with a qualitative approach was performed.Results           The results revealed the following domains to describe the nurse's dilemma when the patient refuses vital care interventions: patients? reasons for treatment refusal, the nurse's understanding of the patient's refusal of care and contradictory legislationConclusion     More knowledge and discussion of the patient's decision-making competence is needed for both the nursing profession and those who make decisions on legislation..

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

The aim of this study was to explore transsexuals? identity formation and experiences related to cross-sex hormone treatment, as well as to become absorbed in the narrative approach. To be able to participate in transsexuals? identity formation, life stories were well suited as a theoretical approach. Life stories can be seen as socially situated actions according to Mishler, where individuals? identity formation can be seen as both identity performances and identity claims.

In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts. In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate. The life cycle of P. brassicae is not well understood.
