We aimed to estimate the optimal time of delivery and investigated the residual risk of fetal death after viability in otherwise uncomplicated monochorionic diamniotic twin pregnancies.A database of 576 completed multiple pregnancies that were managed in our tertiary referral fetal medicine department between 1996 and 2007 was reviewed and the uncomplicated 111 monochorionic and the 290 dichorionic diamniotic twin pregnancies delivered after 24 weeks were selected. The rate of fetal death was derived ...

The research on tourism is constant and unending; food and wine tourism research still represents a small part inside this wider field. Wine tourism and events are critical for sustainable development of rural areas. In this context, the emotional bond between the wine tourists the regions and the producers that they visit is created, not just through the wine as a product, but also through a set of hedonic features that are present in the visit and tasting experience. To reach the research objectives, ...

This study develops a scale to measure wine tourism experiences and was tested in Portugal, in two of the main wine tourism centres: Porto and Madeira. The wine experience scale combines experience traits with the traditional approach to scales related to wine tourism. The development of the scale follows the most recognised validated procedures. Data were collected from a total of 647 international wine tourists in the wine cellars of the two main fortified wine tourism regions visiting areas: ...

Tourism is a phenomenon that moves millions of people around the world, taking as a major driver of the global economy. Every year, much due to the frequent changes in the tourism environment, fosters competition between and within tourist destinations. In specific, the wine tourism activity involves the participation of a certain group of people, called wine tourists, who look for experiences related to wines and wineries at wine tourism destinations. Trends in global tourism demand suggest the ...

Abstract Historically known as the yellow fever mosquito, Aedes aegypti invaded Madeira Island in 2005 and was the vector of the island’s first dengue outbreak in 2012. We have studied genetic variation at 16 microsatellites and two mitochondrial DNA genes in temporal samples of Madeira Island, in order to assess the origin of the invasion and the population structure of this mosquito vector. Our results indicated at least two independent colonization events occurred on the island, both having a ...

Given the high prevalence of patients with hip deformities and no ongoing hip dysfunction, understanding the anatomic factors predicting the symptomatic state is critical. One such variable is how the spinopelvic parameters (SPPs) may interplay with hip anatomic factors.SPPs and femoral- and acetabular-specific parameters may predict which patients will become symptomatic. The purpose was to determine which anatomic characteristics with specific cutoffs were associated with hip symptom development ...

The calculation of an indicator values has challenges as the calculation may need to combine some aspects of quality while addressing different levels of abstraction. Knowledge graphs (KGs) have been used successfully to support flexible representation, which can support improved understanding and data analysis in similar settings.

No systematic analysis to date has yet compared studies among these groups to determine differences in radiographic signs of FAI. Methods A systematic review of existing literature was performed to determine the prevalence of radiographic signs of FAI among athletes, asymptomatic ...

Self-consistent theoretical models have been developed in order to investigate the early and remote flowing afterglows of a surface-wave Ar–O2 microwave discharge generated at 2.45 GHz in a 0.5 cm diameter tube at pressures between 1 and 12 mbar. The early afterglow that occurs downstream of the discharge fills up the tube that connects the discharge region with the large-volume processing reactor, where the late afterglow develops. The models provide the time-dependent density profiles of different ...

The main concerns associated with the establishment of a self-consistent model for N2 discharges and post-discharges at low pressures (typically p ∼ 1 Torr), as well as in mixtures of this gas with O2 and CH4 are analysed and discussed. The focus is given on the coupling of the various kinetics involved: electrons, vibrational molecules N2 , dissociated atoms N(4S), ionic species, and various atomic and molecular electronic states. The impact of N2–O2 and N2–CH4 systems on the applications is briefly ...

The effect of scene dimensionality on colour constancy was tested with real scenes and objects. Observers viewed a three-dimensional (3-D) scene, or its two-dimensional (2-D) planar projection, through a large beam-splitter that projected the virtual image of a real test object (a cube or its 2-D projection) so that it appeared part of the scene. Test object and scene could be illuminated independently with high chromatic precision. In each trial, the illuminance of the scene changed abruptly from ...

This work extends our previous analysis of the nitrogen pink afterglow, by comparing our model predictions with the recently reported measurements of metastable N(2P) atoms and N2(a1Πg) molecules. It is shown that both species reveal the presence of a characteristic maximum on their populations, occurring downstream from the discharge after an initial stage of decrease. Such behavior is a consequence of the V-V pumping-up mechanism taking place during the relaxation in the afterglow, which is followed ...

The effect of scene complexity on colour constancy was tested with a novel technique in which a virtual image of a real 3-D test object was projected into a real 3-D scene. Observers made discriminations between illuminant and material changes in simple and complex scenes. The extent of colour constancy achieved varied little with either scene structure or test-object colour, suggesting a dominant role of local cues in determining surface-colour judgments.

The kinetic modeling of low-pressure ( torr) stationary nitrogen discharges and the corresponding afterglows is reviewed. It is shown that a good description of the overall behavior of nitrogen plasmas requires a deep understanding of the coupling between different kinetics. The central role is played by ground-state vibrationally excited molecules, N2, which have a strong influence on the shape of the electron energy distribution function, on the creation and destruction of electronically excited ...

Color matching experiments use, in general, stimuli that are poor representations of the natural world. The aim of this work was to compare the degree of color constancy for a range of illuminant pairs using a new matching technique that uses both real objects and three-dimensional (3-D) real scenes. In the experiment, observers viewed a 3-D real scene through a large beamsplitter that projects on the right-hand side of the scene (match scene), the virtual image of a 3-D object (match object) such ...
