Background: Magnetization transfer (MT) saturation reflects the additional saturation of the MRI signal imposed by an MT pulse and is largely driven by the saturation of the bound pool. This reduction of the bound polarization by the MT pulse is less efficient than predicted by the differential B1-square law of absorption. Thus, B1 inhomogeneities lead to a residual bias in the MT saturation maps.
The purpose of this study is to look into patronage effects of extended supply outside peak hours on regional public transport services. Previous studies have shown that the service frequency is an attribute of great importance for regional passengers, but little is known about the details regarding peak and off-peak frequencies or service hours. The present study addresses this knowledge gap, dep
Convenience food products tend to alter their quality and texture while stored. Texture-giving food components are often starch-rich ingredients, such as pasta or rice. Starch transforms depending on time, temperature and water content, which alters the properties of products. Monitoring these transformations, which are associated with a change in mobility of the starch chain segments, could optim
There is general consensus among road safety researchers that the crash count is not linear with respect to the traffic volume. However, the now-preferred practice of estimating exponents on traffic volume not only results in parameters that cannot be confidently applied in other contexts, but also offers very little insight into the relationship. This paper describes a preliminary investigation o
Purpose/Background: Appendectomy is the standard treatment of acute appendicitis (AA) but conservative treatment has gained success. The need for follow-up after conservatively treated AA is unclear. Hypothesis/Aim: This study evaluates follow-up, recurrence and appendiceal malignancy in conservatively treated AA. Methods/Interventions: This retrospective study included patients with conservativel
Digital sustainability education (DSE) is becoming increasingly relevant in higher Education for Sustainable Development (ESD) and spreads globally. DSE is fueled by the Covid-19-pandemic and urges lecturers, students and universities alike to break new ground in academic teaching. DSE impacts established approaches to ESD and raises questions of ... appropriate online teaching concepts, tools and
This study aims at investigating the thematic patterns in media presentations of Swedish communal social services and the social service workers: how is the media discussion created and established? Which areas are paid the main attention? How is the field being portrayed in media? The study is based on a material found in Swedish newspapers published under a three-month period in the end of 2014.
Access to clean water for drinking and sanitation is a human right. Today water scarcity is a large problem and inequality in access to safe water is a striking truth. In Mozambique, the US foreign aid agency Millennium Challenge Corporation introduced the Rural Water Point Installation Program to increase access to safe water and sanitation – a step towards reducing poverty. 600 water points – in
The growing use of wind energy as major energy source, has led to the construction of large wind farms. The control of such wind farms is typically separated into control at wind turbine level and at wind farm level. The wind farm controller assures that the wind farm produces the demanded amount of power, by providing set-points for the turbines in the farm. The local turbine control assures that
For the performance of the Haldex Active Yaw Control, accurate information about vehicle's lateral dynamic is important. It is for practical reasons not possible to measure the vehicle's lateral velocity, wherefore this state has to be estimated. Previous work [1] with an observer based on a single track bicycle model show promising results but with limited accuracy at high lateral acceler
Our problem considered was whether a virtual environment could be used for development of visual servoing control algorithms.
We have used a virtual environment for the comparison of several kinds of controllers. The virtual environment is done in Java, and it consists of two industrial robots, IRB 2000 and IRB 6, a camera stereo system with two cameras mounted on the end-effector of the IRB 6,
This master thesis is about the regulation of temperature and flow of a steaming fluid when it passes through a heater. There are problems with the present regulation of temperature when the flow rate varies.
The study has dealt with two control methods to regulate temperature and flow of the infusion fluid. These methods are different from the method to date.
The first method is
Since the Financial and Eurozone crisis that erupted in 2009/2010, Germany has seen the rise of a new populist radical right party; the Alternative für Deutschland (AfD). In the years after its establishment in 2013, this party has experienced many electoral successes and entered not only thirteen federal state parliaments, but also the European Parliament in 2014. This development is atypical for
This essay deals with eight women, who all left their native country Bosnia because of the war. Before the flight, each individual is a human being with a role and a place in the structure of society. After the flight, she suddenly finds herself in an unknown community, after having lost her land, her culture, family, friends and identity. The purpose of this essay was to try to give a backdrop of
The aim of my essay was to compare women's and men's ways out of drug abuse, and with help from chosen theories and concepts explain and understand women's situation. My research started with a few questions concerning differences between women's and men's changing process and the role of the social network in this. I also wanted to find out how the women experienced other peop
