Abstract An ice sheet always experience more or less melting during the summer. How much melting that occurs, is mostly determined by the albedo. Albedo is defined as the amount of the incoming shortwave radiation that gets reflected by a surface. When the sunlight starts melting the ice and snow in the summer, the albedo gets lower. The lower albedo itself causes more absorption of radiation, wh
Eventuella beteendemässiga konsekvenser av pornografianvändande har undersökts flitigt under de senaste decennierna. Forskningen har dock inte inkorporerat kontextuella aspekter av pornografianvändande eller intresserat sig för möjliga samband med användarnas egen sexualitet. Denna studies första syfte var att undersöka pornografianvändande i en icke-klinisk population av 16- till 30-åringar i SveAn increasing body of research has accumulated over last decades investigating the possible behavioral outcomes and correlates of pornography use. However, research has not incorporated contextual aspects of pornography use or it’s relation with users’ own sexuality. The first aim of this study was to investigate several aspects of pornography use in a non clinical population of 16-30 year olds’ i
A poor air quality creates problems in growing and industrialized cities. It is known that there is a significant correlation between rising air pollutions and rising numbers of people getting sick of and killed by respiratory diseases. In this study, I investigate how it is possible to use green infrastructure to increase urban ecosystem services that reduce the level of air pollution within the
This thesis has two major purposes: (1) to create a 3D virtual “reconstructive” model of the peristyle with the nymphaeum wall (room b) of the house V 1,7 (House of the Bronze Bull) in Pompeii, and (2) to prepare a probability map based on this model that will show the reliability level for each individual part. The author underlines the importance of recording paradata of the entire workflow. The
In this thesis a chirally symmetric technicolor model is investigated as an extension to the Standard Model. The extension is based on low-energy QCD, with a linear sigma model used to induce the additional degrees of freedom corresponding to the lightest particles of the new techni-sector. The main goal is to incorporate the Standard Model Higgs into the new model, as to explain its vacuum expect
There are high requirements regarding the connection between a hollow-core slab and the supporting wall or beam. One requirement is that the Connection must be able to withstand design loads parallel to the slab. STARKA Betongelement AB provides this by casting concrete and a steel Connection detail in one of the voids in the hollow-core slab on site. There have been questions about the reliabilit
Until rather recently, safety from a traffic perspective has almost exclusively been described by accident statistic which in itself does not reveal the true safety issues. For this reason the use of traffic safety indicators has become more frequently used as a complement to describe the traffic safety situation. This thesis treats the behavioral differences of Norwegian and Danish cyclists from
Increasing heavy traffic on the roads raises demands on pavements and especially the binder of the pavements. The rutting and other deformations resistances are constantly improved. As a part of the development wax mixes and polymer modified variants are produced. These products are not anymore possible to classify with traditional test methods, requiring new measurement technique and new criteria
There are only a few construction projects that include a Logistic Manager today. In many cases the profit is hard to see, since the involving tasks in logistics are the same even if there is a Logistic Manager included in the project or not. It may seem like the job is already taken care of and that a Logistic Manager therefore would be unnecessary. Even though the project tasks are the same, the
Sammanfattning Den svenska bostadshyresmarknaden präglas av en öppenhet för alla grupper i samhället. Syftet med den svenska bostadspolitiken är att skapa social, ekonomisk och etnisk mångfald i alla stadsdelar genom att kunna erbjuda prisvärt boende samt hyra oavsett inkomst. För att nå detta mål, införde Sverige samma hyressättningssystem för alla typer av bostäder, oavsett om de tillhandahölls Summary The Swedish housing market is characterized by being accessible to all groups in society and by the objective of achieving an overall social cohesion in its rental market. The purpose of this is to further integration and counter segregation by creating diverse neighborhoods accessible to all groups in society regardless of social status and for a reasonable price. To reach this goal, Swed
The purpose of this paper is to investigate the response of the stock prices of firms based on NASDAQ Select Market, during the Credit Rating Announcements made by one of the major rating agencies, Standard and Poor’s, before and after the Great Financial Crisis of 2007-2008. The test procedure is the application of the event study by which we are going to investigate whether or how much the marke
Sedan 1995 har det inom den svenska aktiebolagsrätten funnits en regel om uppskjuten apport. Denna regel står att finna I aktiebolagslagens 2 kapitel 9§ a-c. Dessa bestämmelser syftar i första hand till att förhindra att reglerna om apport kringgås vid bildandet av ett bolag. Detta kringgående skulle ske genom att bolagets stiftare och ävenså aktieägare köper aktier i bolaget och betalar dessa kon
This paper examines the relationship between inflation expectations and consumption attitude regarding durable goods. It does so using cross-sectional data on Swedish households collected on behalf of Konjunkturinstitutet. We use an ordered probit model, with a number of controls, to obtain estimates of the aforementioned relationship. In contrast to established macroeconomic assumptions, our resu
Gambro is one of the biggest developers and manufactures of machines for hemodialysis treatments in the world. One component on their machines, the air level detector (ALD), has been identified to have a possibility to be further improved from usability perspective. The ALD is located at the front of the machine and has the function to hold the venous drip chamber in place and detect whether or no
Internet och den reella världen kan inte längre skiljas från varandra och föreställningen om den reella och virtuella världen som två separerade väsen kan inte längre ses som knivskarp. För de digitalt infödda ungdomarna är nätet idag en högst verklig plats där de umgås och visar upp sig själva. I den polymedia ekologi som tekniken och internet med alla dess olika plattformar medfört, erbjuds ungd
Public-Private Partnerships (PPP) have been embraced across the globe the past decades, with the driving forces varying across countries. Considering the relatively scarce usage of PPP in Sweden it appears highly relevant to identify the constraints for realising PPP projects. The outcome of such a study provides better understanding on what factors could constrain countries with low utilisation,
