I denna rapport redovisas ett examensarbete av Yvonne Svensson i samarbete med Claes Edman, entreprenör. Projektets mål har varit att designa ett poolhus med inredningsförslag till uppdragsgivarens koncept Poolhus/poolskydd som ska vara så pass flexibel att den passar en bred kundgrupp. Konceptet är sekretessbelagt och kommer därför inte gå närmare in på konstruktionsfrågor gällande poolskyddsdelen. Poolhuset kommer att fungera som en gäststuga och har bastu, utomhusdusch, utomhuskök samt en veranda. Inspirationen till inredningen och formen till poolhuset är ifrån ett marint tema. I faktainsamlingen ges en överblick vem som är målgruppen genom en enkätinsamling och målgruppsanalys även en konkurrentanalys har genomförts. Här presenteras även en funktionsanalys och en diskussion om trender utförs. I idégenereringskapitlet presenteras framtagningen av koncept och de fem olika koncepten som redovisades för uppdragsgivaren halvvägs in i projektet. I kapitlet genomförande så redovisas det valda konceptets väg till resultatet. Till sist visas resultatet med hjälp av datorgenererade bilder, ritningar med mått samt bilder på en skalmodell som gjorts. Slutresultatet är ett poolhus som har ett mervärde som kommer att öka statusen och komforten för dem som har en pool. / The essay describes the bachelor project by Yvonne Svensson in collaboration with Claes Edman, entrepreneur. The projects goal was to design a pool house and to design an interior for this house inside and outside. The concept is confidential and for that reason I will not elaborate on the designs construction details. The pool house function is a guesthouse in the season and offseason it will function as a storage place and a lounge area. The house has a sauna, an outdoor shower, a porch and also an outdoor kitchen. The essay provides an overview of the target group and competitor analysis. Five different concepts will be reported and which of them I and my commission giver decided to continue to work with. The end product is a pool house that gives a value and comfort in the daily routine for them who has a pool.

Source term modeling is the key feature in predicting the consequences of releases from hazardous fluids. Aqueous ammonia serves the purpose of a reducing medium and is replacing anhydrous ammonia in most of the Selective catalytic reduction (SCR) units. This newly developed model can estimate the vaporization rate and net mass evaporating into the air from a multicomponent non- ideal chemical spill. The work has been divided into two parts. In the first step a generic, dynamic source term model was developed that can handle multicomponent non-ideal mixtures. The applicability of this improved pool model for aqueous ammonia spills was then checked to aid in the offsite consequence analysis of aqueous ammonia spills. The behavior of the chemical released depends on its various inherent properties, ambient conditions and the spill scenario. The different heat transfer mechanisms associated with the pool will strongly depend on the temperature of the liquid pool system at different times. The model accounts for all the temperature gradients within the contained pool and hence helps us establish better estimation techniques for source terms of chemical mixtures. This research work will help obtain more accurate and reliable liquid evaporation rates that become the critical input for dispersion modeling studies.

Much evidence now exists to show that unbalanced DNA precursor pools cause DNA replicational infidelity in vitro. However, there are relatively few data with in vivo systems. Experiments were performed therefore, to determine if unbalanced precursor pools could be induced in vivo and if so, what affect this would have on various genetic markers. The nucleoside thymidine was shown to be completely non-toxic to the rat when administered orally, negative in the dominant lethal assay and was only marginally clastogenic in the micronucleus test. Treatment of human lymphocyte chromosomes with the essential amino acid arginine, arrested cell division possibly due to a predominance of arginine-rich histones limiting the chromatin-condensation during mitosis. Thymidine administered i. p. to mice induced marked increases in the proportions of abnormal sperm and the same effect, to a lesser extent, was seen in rats. The affected germ-cell stages were the mid - to late pachytene spermatocytes. These affects were probably due to base-misincorporation occuring during unscheduled DNA synthesis. The purine nucleoside adenine caused dose-related increases in the frequency of abnormal sperm in mice. In rats, a proportion of animals given 150mg/kg adenine showed high levels of abnormal sperm whilst others were unaffected. Examination of mice in the generation revealed that the damage to the germ-cells was transmissible. The simultaneous administration of deoxycytidine with excess thymidine to mice partly inhibited the effects on sperm morphology indicating that those effects were due to precursor pool imbalance. In addition, an analytical technique was developed to measure nucleosides and bases in the testes using HPLC. The method proved to be rapid, reproducible and quantitative and showed that 1hr following i. p. injection, thymidine levels in the testes increased markedly and thereafter quickly return to control levels. Finally, experiments were initiated to investigate the mechanisms underlying the formation of morphogically abnormal sperm. Polyacrylamide gel electrophoresis was used to identify membrane proteins in sperm from both control and treated animals.

In this first manuscript, the research purpose was to explore stakeholders perceived roles in mobilizing pool safety knowledge and to understand the barriers associated with the uptake of pool safety initiatives. Six water safety experts were interviewed to gain insight into their perceptions and diverse roles. Using grounded theory, it was determined that stakeholders perceive they have a role in mobilizing pool safety knowledge. Three overarching themes emerged from the data which aligned with a proposed Drowning Prevention Spectrum: pool safety experts perceive their responsibility in mobilizing pool safety knowledge through their role in developing knowledge and skills as a safety educator; developing and promoting campaigns and products through their role as a marketer of behaviour change; and through their role in the development and enforcement of policies and legislation. Interviewees were also asked what they perceived as some of the major barriers to the uptake of pool safety information and initiatives. Interviewed stakeholders revealed that the main social ecological barriers included personal barriers (cost and time), social barriers (policy and awareness), and physical barriers (backyard aesthetics). The results of the first manuscript demonstrates that even though all interviewed stakeholders perceive they have a role in mobilizing pool safety knowledge, there are still barriers in the uptake of pool safety knowledge by citizens and pool owners. The second manuscript focused on using Weinreich’s (2010) process model and semi structured interviews with six pool safety experts as well as marketing experts to create a social marketing campaign to emphasize the risks associated with portable pools. This article goes through the six steps outlined by Weinreich (2010) as well as using theories in the development of the campaign messages. Through interviews, experts gave their opinions and suggestions on most effective campaign messages, images, target audience, and promotional channels. The mock campaign ads were then presented to the marketing team in whom they gave their ideas and suggestions on how to hook the target audience in wanting to learn more about portable pool safety. A final campaign was crafted and will be implemented in a future City of Ottawa initiative.

Due to increased adoption of irrigation and advancements in technology, producers in the Mississippi Delta have been unsustainably depleting the water stocks in the Mississippi River Valley Alluvial Aquifer (MRVAA). This research investigates the impacts of various regulatory threats uniformly applied to heterogeneously located producers to avert further overexploitation of the MRVAA. If a regulatory threat successfully incentivizes reduction of producers’ extraction rates, costly implementation of a binding limited-use regulation could be avoided. Laboratory experiments incorporating the major characteristics of the MRVAA were conducted to test two threatened uniform policies, limited-use and moratorium. The main finding of the research is that even with the threat of a moratorium, the regulatory trigger point was too lax to result in significantly slowing over exploitation of the water resource.

A study of pool boiling of a dielectric liquid (PF 5060) from single-layered enhanced structures was conducted. The parameters investigated were the heat flux, the width of the microchannels and the microchannel pitch. The boiling performance of the enhanced structures increases with increase in channel width and decrease in channel pitch. Simple single line curve fits are provided as a practical way of predicting the data over the entire nucleate boiling regime. The influence of confinement on the thermal performance of the enhanced structures was also assessed. The main parameter investigated was the top space (0 mm { 13 mm). High-speed visualization was used as a tool . For the total confinement ( = 0 mm), the heat transfer performance of the enhanced structures was found to depend weakly on the channel width. For >0 mm, the enhancement observed for plain surfaces in the low heat fluxes regime is not present for the present enhanced structure. The maximum heat flux for a prescribed 85 oC surface temperature limit increased with the increase of the top spacing, similar to the plain surfaces case. Two characteristic regimes of pool boiling have been identified and described: isolated flattened bubbles regime and coalesced bubbles regime. A semi-analytical predictive model applicable to pool boiling under confinement is developed. The model requires a limited number of empirical constants and is capable of predicting the experimental heat flux within 30%.
