The O-arm system is a mobile intraoperative imaging system that is comprised of fluoroscopy and cone beam CT. The configuration of the O-arm system with absence of patient table and a broad beam width (165 mm in isocenter) brings new practical and physical requirements on how to perform dose measurements. The purpose of this study was to describe a method that overcomes this and makes it possible
A measurement of the parity-violating decay asymmetry parameter, ab, and the helicity amplitudes for the decay.Lambda(0)(b) -> J/psi(mu(+) mu(-)) Lambda(0)(p pi(-)) is reported. The analysis is based on 1400 Lambda(0)(b)and (Lambda) over bar (0)(b) baryons selected in 4.6 fb(-1) of proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By co
Fish are more sensitive to introduced disturbances from synthetic endocrine disrupting compounds during early life phases compared with mature stages. 17α-Ethinylestradiol (EE2), which is the active compound in human oral contraceptives and hormone replacement therapies, is today ever present in the effluents from sewage treatment plants. EE2 targets and interacts with the endogenous biological sy
A disadvantage of prostate-specific antigen (PSA) for the early detection of prostate cancer (PCa) is that many men must be screened, biopsied, and diagnosed to prevent one death.
Ancient DNA trapped in the matrices of ceramic transport jars from Mediterranean shipwrecks can reveal the goods traded in the earliest markets. Scholars generally assume that the amphora cargoes of 5th-3rd century B.C. Greek shipwrecks contained wine, or to a much lesser extent olive oil. Remnant DNA inside empty amphoras allows us to test that assumption. We show that short 100 nucleotides of an
Estrogen receptors (ers) not only are activated by hormones but also interact with many human-derived environmental contaminants. Here, we present evidence for four expressed er genes in Atlantic salmon cDNA - two more ers (erα2 and erβ2) than previously published. To determine if er gene expression differs between two adult life-stages we sampled 20 adult salmon from the feeding phase in the Balt
Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from >= 6 to >= 9 jets. No evidence is foun
For the first time, Pulsed Field Gradient-Nuclear Magnetic Resonance, a powerful noninvasive tool for studying the dynamics and structure of complex-gels, has been used to measure diffusion of probe molecules in aqueous solutions/gels of noncommercial purified pig gastric mucin (PGM), in a concentration range up to 5 wt%. Complementary data were obtained from rheology measurements. The combination
This thesis analyzes blood diamonds and the human rights issues surrounding them. The problems they pose and the promises and limitations of the Kimberly Process are covered along with the development and future impact of man-made diamonds on the demand side of the blood diamond problem. There are two main sections--the first covers blood diamonds and the second man-made diamonds. The introduction
Polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. The Baltic grey seal (Halichoerus grypus) and the Eurasian otter (Lutra lutra) are top predators and especially exposed to high levels of lipophilic pollutant in their diet due to biomagnification. In the current
This thesis aims to analyze female sexual and bodily rights in Lebanon from a queer perspective, focusing on issues such as space and visibility and the strategically neglecting of historical existence of female narratives, referred to as conceptual anorexia. The thesis was preceded by a field work conducted in Beirut where observations of the field and interviews with LGBTQ- and/or feminist activ
The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth
Cities are becoming smart to cope with the challenges associated with urban development. One of the cities trying to become smart is the City of Stockholm, which in 2017 adopted a strategy to become the world’s smartest and most connected city. However, becoming a smart city is not easy. The transformation requires a new organizational approach and innovation in management, which the City of Stock
I denna kandidatuppsats undersöks den använda retoriken av den Nationella Kampanjen för rätten till laglig, säker och gratis abort i Argentina. Syftet med studien är att under- söka om den reproduktiva styrningen håller på att förändras. Det valda empiriska materialet består av ett dokument som skrivits av den Nationella Kampanjen för rätten till laglig, säker och gratis abort i Argentina. UppsatsThis bachelor thesis investigates the rhetoric used by the National Campaign for the right to legal, safe and free abortion in Argentina. The purpose of the study is to research if the reproductive governance of Argentina is in transition. The empirical material selected consist of a document written by the National Campaign for the right to legal, safe and free abortion in Argentina. The theoreti
Denna fallstudie studerar och analyserar hur Arla bemöter negativa kommentarer på Instagramkontot Arla Sverige. Vi belyser hur Arla förhåller sig till teorier inom Is-sues Management i sin kommunikation på ett av sina Instagramkonton. Vi använder en netnografisk observation samt intervjumetod som insamlingsmetod. Den netnografiska metoden används för att samla in kommentarer från Instagramkontot AThis case study aims to investigate how Arla responds to negative comments posted to their social media in order to gain knowledge of how they take into consideration Issues Management in their social media communication. Through a netnographic observation and two in-depth interviews with Arlas press- and media manager we gather empirical material. The netnographic observation is used to gather co
Scenario: Using adaptive dynamic theory, expose a monomorphic prey population to two habitat types and a visual predator. Questions: What circumstances can lead to the evolution of polymorphic crypsis? How is the outcome affected by the dispersal pattern of the prey and predator, by the amount of predation, and by the trade-off strength between the habitats? Mathematical method: I modelled three d
This article reports on a search for dark matter pair production in association with bottom or top quarks in [Formula: see text] of [Formula: see text] collisions collected at [Formula: see text] TeV by the ATLAS detector at the LHC. Events with large missing transverse momentum are selected when produced in association with high-momentum jets of which one or more are identified as jets containing
It is relevant to consider uncertainty in individual predictions when quantitative structure-activity (or property) relationships (QSARs) are used to support decisions of high societal concern. Successful communication of uncertainty in the integration of QSARs in chemical safety assessment under the EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) system can be faci
