Computed tomographic (CT) pulmonary angiography has been established as a first-line diagnostic technique in patients suspected of having pulmonary embolism. Risk stratification is important in patients with pulmonary embolism because optimal management, monitoring, and therapeutic strategies depend on the prognosis. Acute right-sided heart failure is known to be responsible for circulatory collapse and death in patients with severe pulmonary embolism. Acute right-sided heart failure can be assessed at CT pulmonary angiography by measuring the dimensions of right-sided heart cavities or upstream venous structures, such as the superior vena cava or azygos vein. The magnitude of pulmonary embolism can be calculated at CT pulmonary angiography by applying angiographic scores adapted for CT (Miller and Walsh scores) or dedicated CT scores (Qanadli and Mastora scores). The advent of CT pulmonary angiography performed with electrocardiographic gating permits new advances in assessment of acute right-sided heart failure, such as measurement of the ventricular ejection fraction. Although such findings may be useful for assessment of treatment effectiveness, their effect on prognosis in patients with severe pulmonary embolism is debated in the literature. (C) RSNA, 2006.

Erosion and deposition modelling should rely on field data. Currently these data are seldom available at large spatial scales and/or at high spatial resolution. In addition, conventional erosion monitoring approaches are labour intensive and costly. This calls for the development of new approaches for field erosion data acquisition. As a result of rapid technological developments and low cost, unmanned aerial vehicles (UAV) have recently become an attractive means of generating high resolution digital elevation models (DEMs). The use of UAV to observe and quantify gully erosion is now widely established. However, in some agro-pedological contexts, soil erosion results from multiple processes, including sheet and rill erosion, tillage erosion and erosion due to harvest of root crops. These diffuse erosion processes often represent a particular challenge because of the limited elevation changes they induce. In this study,we propose to assess the reliability and development perspectives of UAV to locate and quantify erosion and deposition in a context of an agricultural watershed with silt loam soils and a smooth relief. Erosion and deposition rates derived from high resolution DEM time series are compared to field measurements. The UAV technique demonstrates a high level of flexibility and can be used, for instance, after a major erosive event. It delivers a very high resolution DEM(pixel size: 6 cm) which allows us to compute high resolution runoff pathways. This could enable us to precisely locate runoff management practices such as fascines. Furthermore, the DEMs can be used diachronically to extract elevation differences before and after a strongly erosive rainfall and be validated by field measurements. While the analysis for this study was carried out over 2 years, we observed a tendency along the slope from erosion to deposition. Erosion and deposition patterns detected at the watershed scale are also promising. Nevertheless, further development in the processing workflow of UAV data is required in order to make this technique accurate and robust enough for detecting sediment movements in an agricultural watershed affected by diffuse erosion. This area of investigation holdsmuch potential as the images processing is relatively new and expanding. [less ▲]

In light of the principle of equality, German, Belgian and British election law contain some legal rules that tend to distribute the faculty to influence the composition of the elected assemblies equally among the governed people, and others that tend to distribute it unequally. The inequality caused by the latter group may be to some extent legally justified by concerns for the general interest, but also provides rulers with means that help them to remain in power, which is hardly justifiable from a legal perspective. In these legal systems, parties are expected to gain a significant portion of the people’s support: not only should the parliament (as a whole) and its members (as individuals) represent the governed people, but the parties themselves are expected to be sufficiently representative of the people in order to access the legislative assemblies. Notably, this thesis draws examples from the case law of the European Court of Human Rights, from which relevant decisions are mentioned here. [less ▲]

Root water and nutrient uptake and its relation to environmental factors is one of the least understood components in the terrestrial water balance and is of high importance for water resources management, ecology and agriculture. As the processes in the soil-plant continuum are complex and inextricably intertwined, alternative, non-invasive measurement methods are necessary to unravel spatial and temporal dynamics of the system. Electrical resistivity tomography (ERT) has been proposed as a promising technique, since bulk resistivity maps and their temporal evolution may serve as a proxy for changes in soil moisture and pore water salinity, amongst others. However, the variables affecting the measured bulk electrical resistivity often change simultaneously in natural environments and not all influencing factors are yet well understood (e.g. influence of root biomass). Therefore, the method needs field-specific calibration. In addition to limitations due to signal-to-noise ratio and data inversion strategies, this implies that ERT still needs further development and research efforts for its use to characterize the soil-plant continuum.

Detection of a reduction in forage intake is particularly relevant in grazing animals due to its negative effect on animal performance. Estimations of intake reduction using faecal markers can be inaccurate due to the time delay between a change in forage intake and the subsequent change in faecal output. This delay may vary depending on forage quality and marker type. A pen study was conducted for 29 days to test the efficacy of liquid (PEG = polyethylene glycol) and solid (alkanes and CrCl3 = chromium chloride) phase faecal markers to detect a reduction in intake by steers of diets that varied in forage quality. Ten Brahman cross steers (296 ± 16 kg) were allocated equally to diets of leafy, high quality buffel grass (Cenchrus ciliaris) hay and stemmy, low quality buffel grass hay. Hay was offered ad libitum from day 1 to 7, at 90% of voluntary intake from day 8 to 14 and then reduced by 8% each day from day 15 to 24. On day 5 each steer was dosed with two slow release alkane capsules; also, steers received a single daily dose of PEG and CrCl3 at 09:00 on days 5 to 24. Actual and marker derived estimates of forage intake over days 10 to 22 were assessed by repeated-measures analysis of variance. Overall marker recovery rates were satisfactory (0.92 to 1.03) and there was a significant (P < 0.001) progressive decrease in daily recovery rate over time for all markers and diets. Actual and marker-determined forage intake declined over the course of the experiment for both leafy and stemmy hay diets (P < 0.001) for all three markers. There was a lag of 3 to 5 days to detect a significant reduction in estimated intake by steers using markers. The lag period was similar for both liquid and solid phase markers. Results of this experiment indicated that decreases in forage intake by cattle could be detected using indigestible faecal markers, albeit in association with (i) progressively larger reductions in actual forage intake, and (ii) a time lag of 3 to 5 days between the decrease in actual intake and its statistical detection using faecal markers.

An employers’ alliance (EA) is a group of employers who team up to hire and share workers. It is presented as ‘flexicurity in action’, in other words, as a tool allowing employers and workers to find new win-win compromises at the company level. Even when motivated by the best of intentions and with all pre-conditions fulfilled, implementing such a new inter-organisational employment scheme might end in failure. We will describe such a failure with the help of a case study showing how employers considered the EA scheme as a possible solution for the informal multi-activity of their staff. We then explore some of the reasons for the failure in implementation and describe how a supporting third party function, which we call the terceisation function, could help the process to succeed and the EA to evolve towards a more equitable and sustainable flexicurity scheme.
