Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys
This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

Klimatflyktingar, en fråga om samarbete? : En studie om internationellt samarbete i kontexten klimatflyktingar
I takt med att de globala klimatförändringarna fortsätter kommer konsekvenserna bli allt mer ödesdigra. Vissa av dessa konsekvenser förbises ofta i den globala debatten och i världspolitikens inflytelserika kretsar. Uppskattningar gör gällande att så många som 200 miljoner människor blivit förskjutna som en konsekvens av klimatförändringarna. Detta aktualiserar frågan om klimatflyktingar. Syftet med denna uppsats är att studera varför det internationella samarbetet gällande klimatflyktingar kan betraktas som begränsat.
Risk för exponering av växtskyddsmedel i växthusmiljö
Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
Medarbetares uppfattning av säkerhetsklimatet: Skillnader utifrån anställningsår och anställningsform avseende ledningens och arbetsgruppens säkerhetsarbete
Syftet med föreliggande studie var att undersöka om det fanns någon skillnad mellan de som varit anställd få respektive många år samt mellan de som arbetade dagtid och de som arbetade skift gällande uppfattningen av säkerhetsklimatet avseende både ledningen säkerhetsarbete och arbetsgruppens säkerhetsarbete på ett bruk inom massa- och pappersindustrin. Totalt deltog 92 medarbetarna i studien och dessa fick besvara frågeformuläret, Nordic Safety Climate Questionnaire (NOSACQ-50). Resultatet visade att de som arbetat många år uppfattade både ledningens och arbetsgruppens säkerhetsarbete som bättre än de som arbetat få år. Det visade sig även att de som arbetade dagtid uppfattade, om än bara i närheten till signifikant, ledningens säkerhetsarbete bättre än de som arbetade skift. Att ha en förståelse kring att det finns skillnader i uppfattningen av säkerhetsklimatet och vad dessa kan bero på kan vara av vikt för att skapa ett bättre säkerhetsarbete på företaget, något som diskuteras i uppsatsen..
Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Tiden, hälsan och familjen : En intervjustudie av tidsbrist och dess konsekvenser för hälsan
Aim and scientific issuesThe aim was to identify potential health risks, for full-time working parents with small children, caused by time shortage. The intention was to better understand and help this particularly time-pressured group in society to achieve a healthier lifestyle. The identification was built upon their own opinions about possible health risks and upon an interpretation of the health risks from a health promoter?s perspective.How do full-time working parents with young children handle time-shortage in a health perspective, specified in the categories: sleep, recovery, nutrition, physical activity, social health and mental health?What consequences for health does time?shortage have for full-time working parents with young children?What do parents with young children think could help them to obtain a better health in everyday life? MethodThe study was based on a literature overview and semi-structured interviews with 6 people who were strategically selected: the interview objects were all full-time working or studying, had one child under 7 and lived together with a partner. All interviews were recorded using two dictaphones and were implemented, transcribed and analyzed by both writers of this essay to increase the reliability of the results.ResultsTime shortage is shown to be handled especially through priorities in the respondent?s lives.
Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås
Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.

Vision Nollenergihus : Energiförsörjning av passivhus med sol- och vindenergi
Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.
