Planering för plats för snöupplag med anslutande dagvattenanläggning

Hamidi, Anton January 2023 (has links)
The study has consisted of creating a place for snow storage with a connecting storm water facility. This is based on findings regarding concentrations of pollutants in Luleå's snow storages in combination with Luleå's standards for design of these storages. For Luleå Municipality, the stormwater issue is relevant as the number of floods will increase as Luleå expands. This results in a greater ratio of hard-made surfaces with increased surface runoff that create risks of flooding and property damage, something that will intensify even further with climate change. Besides this, the runoff concentration of pollutants that are transported out into recipients also increases. The study has been carried out in Luleå, via Luleå Municipality and LTU. The purpose of the study was to answer the following questions:"What concentrations of pollutants are found in Luleå's meltwater?", "What does Luleå' smanagement of snow storage look like, and why?", "Where can a snow storage be placed in Luleå to enable year-round recreation?” and "Which stormwater solution should be chosen to filter pollutants from this snow deposit?". This was answered via seven different means of gathering data: literature studies, field studies/observations, meetings/interviews & E-mail exchanges, selection of a stormwater facility, calculations, simulations, and conceptual design. Through these means, the study concluded that the concentrations of pollutants in meltwater are generally greater than in stormwater, that there are recommendations regarding the size, location and safety of Luleås snow storages, that any snow storage should preferably be located where motor traffic is not present and that its space should be usable year round with regard to recreation, and that a wetland is the most suitable facility for filtering the pollutants in the meltwater from this deposit. Overall, the results conveys that the spaces set aside for snow and meltwater treatment should enable year-round recreation, in addition to their technical functions. However, does the results show nothing in terms of management of extreme cases of rainfall nor any types flooding preventions relating to stormwater management. This paper does not provide any suggestions for a snow storage site nor a stormwater treatment facility for cities with a similar or different climate. The reason that onlyr ecreation and pollution treatment were considered is because these are the most relevant in this context, firstly since toxins are more prevalent in meltwater than in stormwater, and because recreation associated with snow is a given aspect of usage. Thus were a suitable frame of question and suitable means used to generate reasonable and acceptable results.

"Välkommen med din ansökan!" : En studie av saklighet och opartiskhet i tillsättningar av universitetslektorat vid svenska universitet / "Welcome with your application!" : A study of the objectivity and impartiality in appointments of lecturers at Swedish universities

Gustavsson, Ola January 2019 (has links)
This thesis is about hiring processes in the university sector. More particularly, the focus is to identify if the employment of lecturers obeys the principle of objectivity, impartiality and meritocracy. The thesis is based on a so-called mixed method research. Partly, the extent of compliance is tested in a quantitative survey of six Swedish universities, partly each one of the 73 employment notices is analyzed in a qualitative text analysis. The source of information is public government documents from the examined universities. The survey is limited only to include employments until further notice. Therefore, all sorts of temporary employments are excluded. The focus is on the academic subjects of social science, sociology and political economy. Furthermore, the thesis only investigates employments from the years of 2011-2019. To create an understanding in what way the state institutions should handle their exercise of power, the theory Quality of Government (QoG) is being used. The theory is also used for analysis and as an inspiration for the assay scheme, which is used to assess if the employments are considered “narrower” or “more open”. The variables used in the survey are; notification time, number of applicants, the use of peer review, language of the announcement, and a type of “employment conversion”, made possible by law. The result of the thesis shows that there is an extensive amount of employments which in one way or another violates the principle of impartiality. For example: 24 percent of the employments has less than 2 applicants. 17 percent of the employments is missing impartial peer reviews. 89 percent of the employments are only given noticed in Swedish. 29 percent of the announcement texts are written in a narrow, excluding way. To sum up, we can see indications of partial employments. There are distinctive variations between the universities and among the academic subjects. The most important conclusion of this thesis is that all partial employments are a problem, with shortcomings in quality and in public trust as consequences.
