Fishways are installed worldwide to facilitate accessibility to functional habitats and to increase the ecological continuity of rivers. Their evaluations are increasing, but complete studies in the field with wild individuals are still scarce. In the lower Bocq River (Belgium), a pool type fishway was installed in 2011. A combined passive‐integrated‐transponder‐tag and radio‐telemetry system was designed and installed downstream of the dam and in the fishway to analyse fine‐scale individual fish behaviour. Three fish species (brown trout, European grayling, and barbel) were captured in the river; n = 125 fish were tagged and released downstream of the fishway. Behavioural metrics were proposed and used in order to attain a comprehensive view on the efficiency of the fishway, including attraction and entrance efficiency, searching and passage delays, and overall and adjusted passage efficiency. The results indicate a major problem in terms of attraction efficiency (48.9% for the trout, 20.5% for the grayling, and 41.2% for the barbel) and time to find the entrance of the fishway (mean 65.1 hr for the trout and 538.9 r for the grayling). For fish that succeed to approach the entrance of the fishway, the passage efficiency was 86.9% for the trout, 55.5% for the grayling, and 7.1% for the barbel. The time taken to cross the structure was reasonable for the salmonids (mean < 1.5 hr for trout and grayling) but very long (21 hr) for the barbel. Our results underline the necessity of a holistic approach to evaluate fishway efficiency using precise comprehensive metrics and hydraulic characterization. [less ▲]

The identification of pathogen-specific volatile metabolic "fingerprints" could lead to the rapid identification of disease-causing organisms either directly from <i>ex vivo</i> patient bio-specimens or from <i>in vitro</i> cultures. In the present study, we have evaluated the volatile metabolites produced by 100 clinical isolates belonging to ten distinct pathogen groups that, in aggregate, account for 90 % of bloodstream infections, 90 % of urinary tract infections, and 80 % of infections encountered in the intensive care unit setting. Headspace volatile metabolites produced in vitro were concentrated using headspace solid-phase microextraction and analyzed via two-dimensional gas chromatography time-of-flight mass spectrometry (HS-SPME-GC×GC-TOFMS). A total of 811 volatile metabolites were detected across all samples, of which 203 were: 1) detected in 9 or 10 (of 10) isolates belonging to one or more pathogen groups, and 2) significantly more abundant in cultures relative to sterile media. Network analysis revealed a distinct metabolic fingerprint associated with each pathogen group, and analysis via Random Forest (RF) using leave-one-out cross-validation (LOOCV) resulted in a 95 % accuracy for the differentiation between groups. The present findings support the results of prior studies that have reported on the differential production of volatile metabolites across pathogenic bacteria and fungi, and provide additional insight through the inclusion of pathogen groups that have seldom been studied previously, including <i>Acinetobacter</i> spp., coagulase-negative <i>Staphylococcus</i>, and <i>Proteus mirabilis</i>, as well as the utilization of HS-SPME-GC×GC-TOFMS for improved sensitivity and resolution relative to traditional gas chromatography-based techniques.

Enhancements of the Lyman-alpha dayglow have been occasionally observed with IUVS on board MAVEN during periods of increased solar wind activity. They are interpreted as signatures of the penetration of energetic protons and H atoms into the Martian atmosphere. We present the results of Monte Carlo simulations of the energy deposition of the proton/H atom beam and the subsequent Lyman-alpha emission. We compare the observed brightness and the altitude of the emission peak with those calculated based on in-situ measurements of the incident energetic protons. [less ▲]

The goal of this work is to develop a set of simple correlations in order to characterize the optimal off-design performance of an ORC power system. To this end, a 2kWe ORC test rig is investigated as case study and a validated off-design model is used to assess the highest net power generation achievable by the system over its complete range of operating conditions. The off-design model employed is charge-sensitive (i.e. it imposes the total mass of refrigerant in the system) which permits to predict the ORC state (i.e. its pressures, temperatures, mass flow rates, subcooling, etc.) based on the system boundary conditions only. Since such modelling approach and optimization process are time-consuming, a set of simple analytical equations is developed so as to easily predict the optimal performance of the ORC systems.

The capacity to perceive and respond to seasonal changes of day length is essential for flowering plants. Under favourable photoperiod, a mobile stimulus synthesized in leaves moves to the shoot apex and triggers the expression of genes required for the transition to flower initiation. Although transition from vegetative to reproductive state also encompasses a transcriptional response in roots, the internal signalling pathways and how root system architecture adjusts to this changing status remain elusive. Here we show in Arabidopsis that root growth rate increases upon a transfer to flowering-inductive long days while remaining constant under short days. To elucidate genetic components of this response, we performed a meta-analysis of available root-growth and flowering-related arrays and selected genes with overlapping transcriptional profiles for further analyses. Loss of function in a member of the basic leucine zipper transcription factor gene family, hereafter named Insensitive Root Growth-1 (IRG1), was found to suppress photoperiod-response of root growth with no defect in flowering time. We show that sucrose, but neither glucose nor mannitol in the growth medium under long days, is needed to trigger this response. In addition, extending the photoperiod with non-photosynthetic far red light had no effect on root growth of irg-1 mutant, alike wild type Col-0. The expression level of IRG1 in the roots remains low during the daytime and peaks late at night, suggesting that this gene is regulated by the clock’s evening loop. Taken together, our results suggest that IRG1 may be involved in sucrose-mediated stimulation of root growth during the night phase in Arabidopsis. The functional characterisation of IRG1 is currently underway. [less ▲]
