Purpose: Early assessment of radiotherapy (RT) quality in the ongoing EORTC trial comparing primary temozolomide versus RT in low-grade gliomas. Materials and methods: RT plans provided for dummy cases were evaluated and compared against expert plans. We analysed: (1) tumour and organs-at-risk delineation, (2) geometric and dosimetric characteristics, (3) planning parameters, compliance with dose prescription and Dmax for OAR (4) indices: RTOG conformity index (CI), coverage factor (CF), tissue protection factor (PF); conformity number (CN = PF× CF); dose homogeneity in PTV (U). Results: Forty-one RT plans were evaluated. Only two (5%) centres were requested to repeat CTV-PTV delineations. Three (7%) plans had a significant under-dosage and dose homogeneity in one deviated > 10%. Dose distribution was good with mean values of 1.5, 1, 0.68, and 0.68 (ideal values = 1) for CI, CF, PF, and CN, respectively. CI and CN strongly correlated with PF and they correlated with PTV. Planning with more beams seems to increase PTV Dmin, improving CF. U correlated with PTV Dmax. Conclusion: Preliminary results of the dummy run procedure indicate that most centres conformed to protocol requirements. To quantify plan quality we recommend systematic calculation of U and either CI or CN, both of which measure the amount of irradiated normal brain tissue. © 2010 Elsevier Ireland Ltd.

One of the most known disadvantages of the technique of lagoon is the generation of smells, often associated with the presence of hydrogen sulfide (H2S), itself generated by the process of sulfate-reduction. In this paper, we have built a stoichiometric model of sulfate-reduction by providing balanced equations against the elements, electrons, charge and energy. In our model, sulfate acts as an electron acceptor and organic compounds such as lactate, propionate, butyrate, ethanol and acetate are in turn sources of carbon and electron donors. This model allows to quantify the production of sulfide and predicts the variation of alkalinity during the process of sulfate-reduction. [less ▲]

Th e quarry of Romont (Eben/Bassenge, near the Belgian-Dutch border) intersects many endo and exokarsts developing essentially in coarse chalk (calcarenites) of the Maastricht Formation (Upper Cretaceous). It is an appropriate place to study deep and superficial karstification in highly porous rocks. Th e porosity partially inhibits the further development of closed caves (endokarsts) aft er they dewatered. Caves are later fi lled-up by collapsing or when they are cut by solution pipes (exokarsts), and thus partially sealed and preserved in a soft lithology. Th ese solution pipes are generated under river gravels and can go tens of meters deep through calcarenites. [less ▲]

Mediastin pathology includes primary lesion and lymph node invasion. The exploration of this anatomical region remains difficult and even hazardous, particularly to obtain histological biopsies. No invasive diagnostic exploration (thorax tomodensitometry and positron emission tomography) allows a histological precision, so mediastinoscopy remains the gold standard in the mediastinum investigation. However, it is not deprived of risk. Recently, guided biopsies and real-time transbronchial needle aspiration by endobronchial ultrasonography (EBUS) have been shown to increase the diagnostic yield over conventional bronchoscopic techniques. Therefore, EBUS is a suitable alternative to mediastinoscopy in the diagnosis of pulmonary or extra-thoracic malignancy, in the staging of mediastinal lymphadenopathy, and in the evaluation of mediastinal response after induction therapy. In the present paper, we present this new diagnostic approach and clarify the current indications of EBUS. [less ▲]

We prove that the equivalence between Vershik’s standardness criterion and the I-cosiness criterion for a filtration in discrete, negative time, holds separately for each random variable. This gives a strengthening and a more direct proof of the global equivalence between these two criteria. We also provide more elementary original propositions on Vershik’s standardness criterion, while emphasizing that similar statements for I-cosiness are sometimes not so obvious. [less ▲]

This study investigated the differences in pharmacokinetic, urodynamic and haemodynamic parameters in female Beagle dogs in which blood sampling and urethral pressure profiles were performed over 24 h periods, after single or three times daily (T0-T6h-T12h) administration of phenylpropanolamine (PPA). Maximal concentration (Cmax) was reached 2 h after PPA administration (Tmax). The half-life lasted 4 h and, because of bioaccumulation, three times daily administration induced an increase in Cmax. Compared to the control group, a significant increase in urethral resistance was observed at Tmax after 1 week of once daily administrations. After one week of administering PPA every 6 h during the daytime, but not during the night, and despite higher plasma concentrations, the urethral resistance did not increase at any time, compared to the control group. The increase in mean arterial pressure values was compensated by a decreased heart rate. The clinical efficacy of the temporary increase in urethral resistance following single daily administration of PPA in dogs suffering from urethral sphincter mechanism incompetence (USMI) needs to be further investigated in a randomised clinical trial.

Climatic variations happen at all time scales and since the origins of these variations are usually of very complex nature, climatic signals are indeed chaotic data. The identification of the cycles induced by the natural climatic variability is therefore a knotty problem, yet the knowing of these cycles is crucial to better understand and explain the climate (with interests for weather forecasting and climate change projections). Due to the non-stationary nature of the climatic time series, the simplest Fourier-based methods are inefficient for such applications (see e.g. Titchmarsh (1948)). This maybe explains why so few systematic spectral studies have been performed on the numerous datasets allowing to describe some aspects of the climate variability (e.g. climatic indices, temperature data). However, some recent studies (e.g. Matyasovszky (2009); Paluš & Novotná (2006)) show the existence of multi-year cycles in some specific climatic data. This shows that the emergence of new tools issued from signal analysis allows to extract sharper information from time series. Here, we use a wavelet-based methodology to detect cycles in air-surface temperatures obtained from worldwide weather stations, NCEP/NCAR reanalysis data, climatic indices and some paleoclimatic data. This technique reveals the existence of universal rhythms associated with the periods of 30 and 43 months. However, these cycles do not affect the temperature of the globe uniformly. The regions under the influence of the AO/NAO indices are influenced by a 30 months period cycle, while the areas related to the ENSO index are affected by a 43 months period cycle; as expected, the corresponding indices display the same cycle. We next show that the observed periods are statistically relevant. Finally, we consider some mechanisms that could induce such cycles. This chapter is based on the results obtained in Mabille & Nicolay (2009); Nicolay et al. (2009; 2010). [less ▲]
