AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .

Varje år omkommer cirka 500 personer i trafiken och runt 20 000 personer skadas. Betydande riskfaktorer till trafikolyckor är alkohol och droger som blivit allt vanligare förekommande. Det uppskattas att mellan 12 500 ? 15 000 personer kör onyktra på landets vägar dagligen. Rattfylleristerna domineras av yngre och medelålders män och ungefär två tredjedelar av rattfylleristerna har ett alkoholproblem.

The public sector has through the years been exposed to a rather radical alteration. The aim with this alteration has been to make the public sector more effective. It?s a dynamic society that Norrbottens läns landsting (NLL) operates in today and it is therefore of great importance that the managers get a solid foundation to rely on, since they have a central role in the ambition for efficiency. Another reason to educating the managers is that NLL can secure the future pension losses.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Att tidsperceptionen är påverkbar har tidigare påvisats. Studien syftar till att undersöka huruvida tidsperceptionen påverkar fartperceptionen, med hypotesen att när interna taktgivaren går snabbare uppfattas farten som lägre. 28 försöksdeltagare fick under fyra betingelser (Lugn, Stressig, Egen musik och Tyst) utföra tids- och fartestimationer under bilfärd. Inga signifikanta resultat påvisades ifråga om vare sig tidsperceptionen eller dess inverkan på fartperceptionen. Däremot skilde sig prospektiv estimation av medelfart åt beroende på betingelsen.

Road transports stand for a great part of Sweden?s total CO2-emissions. Transports are expected to increase over the coming years, and with those the emissions. A greater environmental awareness leads to increased demands for environmentally friendly transport. The aim of this thesis is to study the consequences of changing transportation modes from road to railway.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Investors? use borrowing as a way to profit from leverage advantages in their portfolios.When investors borrow with their securities as safety for the loan and the value of thesecurities decrease the investor can get a portfolio with more credit than what is covered bythe value of the securities and risk huge losses. To what extent an investor is allowed toborrow with his portfolio as safety depends on the bank or broker and varies between theproviders. By studying available material and in addition to that making an empirical study Iattempt to find out the reason for the varying degrees of leverage possibilities between thebrokers and how the degree of maximum borrowing on the securities are decided. Thefindings show that decision of leverage degree on a security is made after first making aquantitative analysis of the stocks volatility and liquidity and thereafter make a qualitativeanalysis of the company.

Acquiring a former station building can mean that the property owners must familiarize themselves with a lot of planning and building regulations. After the new Planning and Building Act code into force in 2011, the responsibility lie on the developer to ensure laws and regulations. Based on the regulatory framework that is available occurs sometimes balance issues, between care requirements and building codes. The station building in Ormaryd was acquired in 2009 by two individuals who intended to accommodate office and retail space in the building. In doing so a new local plan of the area was established, including regulations on how the building could be used. By including Road safety and noise, the risk was not considered appropriate to use the station building for housing.

Studies have shown that stress is common in the nursing profession.Purpose: The aim was to investigate nurses' experience of stress in the work environment at the University Hospital in Uppsala and how nurses deal with this stress and whether the perceived stress experienced affect patient safety and in what way. Method: The study had a descriptive, qualitative design based on nine interviews. The selection criteria for the study was that participants were nurses and that they had worked at least one year within the profession and that they had experienced stress in their work environment. Data from the interviews was analyzed using the qualitative content analysis method by Graneheim and Lundman. Results: The analysis resulted in three categories: "Stress in the workplace?, "stress management" and "patient safety? and showed that all participants had experienced stress repeatedly in their workplaces.

What affect if an incident is reported?- an interview study with nursesABSTRACTEveryday in health care, there are incidents which can harm patients. However, reporting these incidents is not always a positive experience. The number of incident reports which are documented are a lot fewer than the number of incidents that actually occur. The purpose of the present study was to describe factors that affect nurses? decisions on whether to report an incident or not.

Passagerarna behöver mera tid än säkerhetsinformation eftersom passagerarna har så bråttom att komma ombord, boka bord och handla tax-free. Därmed missar passagerarna viktig säkerhetsinformation som alltid ges vid avgång via fartygets högtalarsystem. Det finns klar och tydlig säkerhetsinformation ombord. Det viktiga är sättet att ge information än att ge mera information. Idag informeras passagerarna via videoskärmar, utrymningskartor på hyttdörrar, via högtalarsystemet ombord, säkerhetsbroschyrer i hytter och information, välutbildad besättning och det är väl skyltat ombord.
