OBJECTIVE: To compare the capacity of transvaginal Doppler ultrasound examination with that of gray scale sonography as an aid in distinguishing benign and malignant pelvic tumors of suspected adnexal origin. STUDY DESIGN: One hundred and fifty-one women scheduled for laparotomy or laparoscopic surgery because of a pelvic mass of suspected adnexal origin underwent ultrasound examination including

Background Low competence levels among nursing staff have been associated with lower quality of elderly care. However, interventions aimed at improving nursing staff competence have not always been evaluated for their possible impact on the quality of elderly care. An educational intervention in the form of a workplace “toolbox” was shown to have positive effects on nursing staff competence and wo

This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e(+/-) mu(-/+), e(+/-) tau(-/+), or mu(+/-) tau(-/+) using 20.3 fb(-1) of pp collision data at root s = 8 TeV collected by the ATLAS detector at the LHC. The numbers of observed candidate events are compatible with the standard model expectations. Limits are set on the cross se

Objective: To update evidence for available therapies in the treatment of hip and knee osteoarthritis (OA) and to examine whether research evidence has changed from 31 January 2006 to 31 January 2009. Methods: A systematic literature search was undertaken using MEDLINE, EMBASE, CINAHL, AMED, Science Citation Index and the Cochrane Library. The quality of studies was assessed. Effect sizes (ESs) an

Den här uppsatsen syftar till att undersöka hur migrantarbetares rättigheter är skyddade inom folkrätt och mänskliga rättigheter. Efter en kort introduktion till internationell migration som fenomen samt de relevanta folkrättsliga normerna övergår uppsatsen till att behandla utlänningars ställning inom mänskliga rättigheter, genom en undersökning av tre av FN:s konventioner för mänskliga rättighetThis thesis examines the international protection of migrant workers. After a brief description of the migration phenomenon and the corresponding international legal framework, the position of aliens under human rights law is addressed through a review of three human rights conventions adopted within the framework of the United Nations. Following that, focus is turned to the international conventi

This thesis aims to evaluating the actual performance of China’s “Feed-in-Tariff” system for wind energy, especially the updated version after 2009 which being part of the Chinese economic stimulus package that intended to help the recovery of the economy from global financial crisis. The research started by looking thoroughly into the evolution and mechanism of the system. Then through a case stu

Lithuania like other Central and Eastern European (CEE) countries has undergone major changes from the communist socio-economic order to the system based on democratic capitalism. This shift towards market economy and the collapse of communist ideology were also reflected in higher education (HE) reforms. Since political parties are the main actors in modern democracies, partisan politics could in

Around the world, the treatment of food waste is a major administrative and environmental problem throughout the food supply chain. Beijing, as any other mega city, is facing vast issues of sustainable food waste treatment in addition to efforts for food waste reduction. Presently the majority of Beijing's food waste is treated together with the mixed residual waste in landfills (53%) and inci

Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. In this Letter, results are presented of a search for events containing one or more such particles, which decay at a significant distance from their production point, using a final state containing charged hadrons and an associated muon. This analysis uses a data sample of proton-proton collisions at

BACKGROUND: There was a decrease 1982-2001 in smoking during early pregnancy in Swedish women. We sought to determine whether there was a parallel decrease in socio-economic inequality in smoking. METHODS: Registry data indicating educational level and smoking status at first antenatal visit in all 2,022,469 pregnancies in Sweden 1982-2001 was analysed. Prevalence differences, odds ratios based on

B vitamins and polymorphisms in genes coding for enzymes involved in one-carbon metabolism may affect DNA synthesis and methylation and thereby be implicated in carcinogenesis. Previous data on vitamins B2 and B6 and genetic polymorphisms other than those involving MTHFR as risk factors for gastric cancer (GC) are sparse and inconsistent. In this case-control study nested within the European Prosp

Family caregivers in palliative care have a need for knowledge and support from health professionals, resulting in the need for educational and supportive interventions. However, research has mainly focused on the experiences of family caregivers taking part in interventions. To gain an increased understanding of complex interventions, it is necessary to integrate the perspectives of health profes

BACKGROUND: Patterns of spatial variation in discrete phenotypic traits can be used to draw inferences about the adaptive significance of traits and evolutionary processes, especially when compared to patterns of neutral genetic variation. Population divergence in adaptive traits such as color morphs can be influenced by both local ecology and stochastic factors such as genetic drift or founder ev

Two searches for supersymmetric particles in final states containing a same-flavour opposite-sign lepton pair, jets and large missing transverse momentum are presented. The proton-proton collision data used in these searches were collected at a centre-of-mass energy root s = 8TeV by the ATLAS detector at the Large Hadron Collider and corresponds to an integrated luminosity of 20.3 fb(-1). Two lept

Trinidad and Tobago is a country with a long history in the hydrocarbon industry. This makes the country one of the wealthiest in the Caribbean region and most poised to be at the edge of innovation and sustainable technology use. However, unsustainable urban development practices have resulted in increasing negative impacts. Governments world-wide have been introducing policies and regulations to

BACKGROUND: The management of femoral neck fractures (FNF) in elderly patients depends on comorbidities, pre-fracture mobility, any hip joint disease, and life expectancy, with treatment typically involving either hemiarthroplasty (HA) or total hip arthroplasty (THA). While cemented femoral stem fixation is standard, there is no clear consensus regarding cemented versus cementless cup fixation in

Water is arguably the world’s most valuable endangered resource, the management of which has been subject of contentious debate that in recent years has gained growing political, economic and media attention. This study intends to make use of that momentum by constructing a framework for quantifying global water crisis risk that is applied to assess both the EU’s share of such risk and the success

In this thesis an optimization of a previously performed inclusive search for beyond Standard Model Physics in same-sign di-lepton final states is performed, but tuned for a doubly-charged Higgs boson decaying to same-sign di-muons. The doubly-charged Higgs boson is a proposed fundamental particle whose existence would provide evidence for theoretical extensions of the Standard Model (SM) of parti

The purpose of this thesis was to examine climate related human mobility in the Southern Africa Development Community (SADC). The adverse effect of climate change in SADC is mainly linked to increasing rainfall variability and a higher frequency or intensity of floods and droughts. These effects are a major challenge for human security. Climate change has emerged as one of the most pressing, unres
