When a new linear accelerator is installed at a department it is of great importance that it is carefully controlled and calibrated before being put into clinical use. This is done with the acceptance test (AT). The mechanical parameters, the beam performance and the reproducibility of the dose output are tested. For each test there is a requirement which must be fulfilled for the machine to pass
The aim of this essay was to analyze how the child sex tourism is looked upon and how Swedish actors on the global arena act against the child sex tourism in Thailand. The United Nations define child sex tourism as "trips organized from within the tourism sector, or from outside this sector but using its structures and networks, with the primary purpose of effecting a commercial sexual relati
The aim of this masters’ thesis is to examine how libraries can better services for patrons with invisible disabilities. My hypothesis is that although libraries are legally obliged to pay special attention to persons with disabilities, in reality the special needs of persons with invisible disabilities are often ignored. Invisible disabilities are disabilities that are not immediately apparent. T
Between drug abuse and a more ordinary life – A qualitative study about former drug addicts experiences of past and present (translated title) The purpose of this study was to examine the experiences of a group of people after leaving a life of drug abuse behind to live a more ordinary life and to interpret these experiences in the light of interactional theory. The theoretic framework used was b
Risk measures such as Value at Risk are highly dependent on a sample of daily returns. The daily return can be measured in different intervals and this thesis examines how the choice of the daily return interval affects derivative pricing, risk measures, fund performance and products with collateral agreements. It is shown that the VaR measure varies significantly with the choice of daily return i
Background: p21-activated kinase 1 (Pak1) phosphorylates many proteins in both normal and transformed cells. Its ability to phosphorylate and thereby activate the estrogen receptor alpha (ER alpha) potentially limits the effectiveness of antiestrogen treatment in breast cancer. Here we studied associations between Pak1 expression and subcellular localization in tumor cells and tamoxifen resistance
Objective: We reviewed the literature on nodal staging in patients with bladder cancer treated with radical cystectomy and lymphadenectomy. Results: Fractionating the lymph node specimen significantly increases the node count, whereas results are contradictory as to whether that increase improves detection of positive nodes. Pathoanatomic data indicate that extending lymph node dissection to the a
Polymer-droplet interactions have been Studied in AOT/water/isooctane oil-continuous microemulsions mixed with an amphiphilic graft copolymer. or with the parent homopolymer (AOT = sodium bis(2-ethylhexyl) sulfosuccinate). The graft copolymer has an oil-soluble poly(dodecyl methacrylate) backbone and water-soluble poly(ethylene glycol) side chains. Pseudo-ternary polymer/droplet/isooctane phase di
This paper contains a joint ESHG/ASHG position document with recommendations regarding responsible innovation in prenatal screening with non-invasive prenatal testing (NIPT). By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive
During the last decade there has been an increase in the use of horizontal organizational relationships (HORs) such as strategic alliances, shared services, and outsourcing. Studies accentuate the unstable, fragile nature of HORS and the importance of directing attention to how these arrangements are formed and how and why they change. The aim in this study is to explore control problems of HORs a
The purpose of this essay was to investigate which factors the individuals found important in the process of becoming a person with a drug-free life. The framing of the questions we had were to get the experiences, thoughts and wishes of the drug users. The survey was based on thematised qualitative interviews and focused in the personal stories of the interviewees. We interviewed four women and f
The purpose of this thesis is to explore whether access to justice in Guatemala can be provided for the Mayan population by the use of their own justice system and what the consequences of its application would be. Prohibiting factors are economical, geographical, linguistic, cultural and institutional in nature. It is clearly the indigenous people that suffer most from the lack of the basic right
Brottet kontakt med barn i sexuellt syfte regleras i 6 kap. 10a§ BrB och tar sikte på situationen när en vuxen, i kontakt med ett barn under 15 år, föreslår eller stämmer träff med barnet i syfte att begå vissa i paragrafen uppräknade sexualbrott. Bestämmelsen har visat på en bristande förmåga att resultera i lagföring. En förklaring till detta är svårigheterna att upptäcka brottet vid en tidpunkThe crime of contact with a child for sexual purposes is governed by Chapter 6, paragraph 10a of the Swedish Criminal Code and regulates the situation when an adult, in contact with a child under the age of 15, proposes or agrees to meet with the child for the purpose of committing certain sexual offenses listed in the paragraph. The provision has shown a lack of ability to result in prosecution
Forecasting foreign exchange rates and financial asset prices in general is a hard task. The best model has often been shown to be a simple random walk, which implies that the price movements are unpredictable. In this thesis models that have been somewhat successful in the past are developed and investigated for different forecasting horizons. The aim is to find models that significantly dominate
Denna uppsats behandlar värderingen av erkännanden som bevis i grova brottmål. Inom svensk rätt råder fri bevisprövning vilket innebär att rätten ska pröva all inkommen bevisning i målet och värdera denna utifrån valfri metod. Detta innebär fortsättningsvis att det inte finns några regler som kan utesluta att endast ett erkännande ligger till grund för bedömningen. Bevisvärderingen av erkännanden
I denna uppsats utreds och analyseras hur rättsväsendet hanterar hatbrott begångna på internet. År 2013 rapporterade Brottsförebyggande rådet att personuppklarningen vad gäller hatbrott begångna på internet är mycket låg. Följaktligen fortsätter uppsatsen med att identifiera orsakerna till den låga personuppklarningen samt de brister rättsväsendet besitter på området. I avslutande del av uppsatsenThis paper is set out to investigate and analyze how the judicial system handles hate crime committed on the internet. In 2013 the Swedish national council of crime prevention (Brå) reported that the clearance rate in terms of hate crime committed on the internet is very low. Hence the paper continues with identifying the causes of the low clearance rate and the shortcomings the judicial system po

The results showed that higher degree of alexithymia was connected to more severe symptoms of exhaustion s
A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs. However, high-efficiency PAs tend to be non-linear, and PAs working in the linear region might ha
Objective. The aim of this study was to determine the prevalence of moderate ischemic mitral regurgitation (IMR) in the contemporary CABG population. We also aimed to correlate the effective regurgitant orifice area (ERO) of any regurgitant mitral valve in patients with coronary artery disease with the semiquantitative integrated scale of IMR. Design. From March 15 through June 15, 2006, 510 conse
