AIM: To prospectively validate two mathematical models for calculating the likelihood of endometrial malignancy in patients with postmenopausal bleeding (PMPB), sonographic endometrial thickness (ET) ≥4.5 mm and no fluid in the uterine cavity.METHODS: This is a prospective observational diagnostic validation study performed in a PMPB clinic in a university hospital. Of 860 consecutive patients, 35
Sociality in spiders has evolved independently multiple times, resulting in convergently evolved cooperative breeding and prey capture. In all social spiders, prey is captured by only a subset of group members and then shared with other, non-attacking group members. However, spiders' propensity to attack prey may differ among species due to species-specific trade-offs between risks, costs and bene
In this study, a synthesis process based on the microemulsion method (ME) was developed with the aim to produce controlled-size starch nanoparticles (SNPs). Several formulations were tested for the preparation of the W/O microemulsions varying the organic/aqueous phase ratios and co-stabilizers concentrations. SNPs were characterized in terms of size, morphology, monodispersity and crystallinity.
This article analyzes Buddhist variations of the so called temple oracle (qian divination) that can be traced historically in the form of sets of answers for people seeking counsel about their future. The ritual is commonly known as a habitual practice in popular religious temples today. Three different ritual texts elucidate modes in which the temple oracle has been woven into Buddhist practice:
Diversification of anaerobic digestion into higher value products, namely volatile fatty acids (VFAs), is receiving interest. One of the biggest challenges with this is recovery of the VFAs. Membrane extraction can be used, and a novel process configuration using a non-porous silicone membrane and water for an extractant is proposed here. This process would enable the
Based on artefactual field experiments, we investigate whether finance professionals differ from a sample of the working population in terms of industry-relevant preferences and personality traits. When adjusting for socioeconomic characteristics, we find only few and less marked differences: finance professionals are less risk averse, less trustworthy, show higher levels of psychopathy and are mo
This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the
This paper presents a solution to the problem of pose estimation in the presence of heavy radial distortion and a potentially large number of outliers. The main contribution is an algorithm that solves for radial distortion, focal length and camera pose using a minimal set of four point correspondences between 3D world points and image points. We use a RANSAC loop to find a set of inliers and an i
Introduction: Many countries in the world are still facing high maternal mortality rates and women still die due to preventable pregnancy- and birth-related causes. This could be prevented with an improvement in the quality of care and yet many countries, especially in the rural areas, have challenges in doing so. In order to understand why is care given in certain way, more qualitative studies ne
Increased awareness regarding nutrition, environmental sustainability, and animal welfare has sparked a trend to shift away from animal proteins. The phenomenon is referred to as the protein shift and has resulted in a higher demand for alternative protein sources. This dissertation aims to study potential opportunities and challenges of using recombinant food proteins expressed in Escherichia col
A significant proportion of the diversity of species seen today are insects and their host plants, and the evolutionary mechanisms behind their radiation have long captured the interest of biologists. The peacock flies of the large genus Tephritis (Tephritidae) use different host plants in the family Asteraceae for their reproduction. There is variation both in use of host plant species and in the
In an industrial plant availability is an important factor since increased availability often gives an increase of final production which in many cases means an increased profit for the company. It has been shown that good strategies for buffer management could increase the availability of an entire plant which motivates further research in this area. To be able to compute the optimal solution to
Non-coagulating milk is unwanted in cheese production because it impairs chymosin-induced coagulation properties in bulk milk. Milk samples were analysed to investigate the coagulation process in non-coagulating milk for comparison with milk samples that have a high coagulation ability. This was done by measuring two peptides after chymosin cleavage, namely para-κ-casein and caseinomacropeptide, i
AbstractEndocarditis, or heart valve infection, can be caused by a number of pathogens, many of which are Gram-positive bacteria. The diagnosis is based on imaging techniques such as echocardiography and on blood culture. The implementation of fast and accurate species identification methods, such as the matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF MS) in
Byggnadssektorn stod för 39 % av energi- och processrelaterade koldioxidutsläpp år 2018 och globala utsläpp från byggnader ökade med 2 % för det andra året i rad. Därför är det viktigt att ta fram lösningar på byggnadsdesign som minimerar klimatpåverkan från byggnader. Samtidigt som produktionen av bostäder och kommersiella byggnader måste vara kostnadseffektiv för att skapa boende och arbetsplatsThe building and construction sector accounted for 39% of energy and process-related carbon dioxide emissions in 2018 and global emissions from buildings increased by 2% for the second consecutive year. It is therefore important to find building design solutions that minimise the climate impact of buildings. At the same time, the production of residential houses and commercial buildings must be co
In the framework of the ATTRACT-uRANIA project, funded by the European Community, we are developing an innovative neutron imaging detector based on micro-Resistive WELL (μ-RWELL) technology. The μ-RWELL, based on the resistive detector concept, ensuring an efficient spark quenching mechanism, is a highly reliable device. It is composed by two main elements: A readout-PCB and a cathode. The amplifi
The thesis concerns inflation measuring and investigates how an alternative to the CPI or GDP-deflator inflation measures could be constructed. The theoretical foundations are based on the quantity theory of money. The measure is constructed as a weighted index where the weights are determined through a statistical method that assigns a weight to a good or a group of goods according to its volatil

This thesis addresses the problem of horizontal incoherence between the first and second pillar of the European Union in its external relations. Horizontal coherence is an important concept for the European Union's legitimacy and strength. Internally, coherence is essential for the Union's democratic legitimacy, as democratic influx comes from the Council. Externally, to the extent incoher
