A soil biodiversity survey coupled with the national soil quality monitoring network?

2021

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…

Tailoring of the solid state properties of Al-Nb mixed oxides: A photoelectrochemical study

2013

Al-Nb containing mixed oxides were grown by anodizing sputter-deposited Al-Nb alloys of different compositions. A photoelectrochemical investigation was carried out in order to estimate the band gap, flat band potential, and conductivity type of these oxides as a function of their composition. The dependence of the band gap on the composition of mixed sp-d metal oxides has been rationalized by using a semiempirical correlation between the difference of electronegativity and band gap of oxides proposed in the literature some years ago and recently tested for regular d-d metal mixed oxides. The band gap increase observed as a function of Al content into the oxides seems mainly depending on th…

Soundscape design through evolutionary engines

2008

Abstract Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: keysounds, key-signals and sound-marks. Sonic Localization Field is defined using a sound attenuation factor and ITD azimuth angle, respectively (Ii, Li). These pairs are used to build Spatial Sound Genotypes (SSG) and they are extracted from a waveform population set. An explanation on how our model was initially written in MATLAB is followed by a recent Pure Data (Pd) impleme…

bbFISH-ing in the sonication fluid

2019

Abstract By 2030, the annual number of combined total hip and knee arthroplasty is estimated to reach 3.5 to 4 million in the US alone. In the context of a constant increase of the number of primary and revision total hip and knee arthroplasty, an increased risk of complication is expected. Prosthetic joint infections (PJIs) represent major cause of healthcare expenditure and morbidity. PJI still remain the most common and feared arthroplasty complication. A rapid and correct diagnosis of infection is decisive for a correct therapeutical management. In this setting, the Academic Emergency Hospital Sibiu adopted and implemented, with the beginning of September 2016, a new strategy for the di…

From job crafting to home crafting: A daily diary study among six European countries

2019

The actions that individuals take to proactively craft their jobs are important to help create more meaningful and personally enriching work experiences. But do these proactive behaviors have implications beyond working life? Inspired by the suggestion that individuals aim for a meaningful life we examine whether on days when individuals craft their jobs, they are more likely to craft non-work activities. It also seems likely that characteristics of the home environment moderate these cross-domain relationships. We suggest that crafting crosses domains particularly when individuals gain resources through high autonomy and high workload at home. We partly supported our model through a daily…

Recurrent lumbar disc herniation: Is there a correlation with the surgical technique? A multivariate analysis

2019

Purpose: The recurrence of a lumbar disc herniation (LDH) is a common cause of poor outcome following lumbar discectomy. The aim of this study was to assess a potential relationship between the incidence of recurrent LDH and the surgical technique used. Furthermore, we tried to define the best surgical technique for the treatment of recurrent LDH to limit subsequent recurrences. Materials and Methods: A retrospective study was conducted on 979 consecutive patients treated for LDH. A multivariate analysis tried to identify a possible correlation between (1) the surgical technique used to treat the primary LDH and its recurrence; (2) technique used to treat the recurrence of LDH and the secon…

The effects of antimicrobial sprays and mouthrinses on supragingival plaque regrowth: a comparative study.

2006

BACKGROUND: Due to the side effects of chlorhexidine digluconate (CHX) mouthrinsing, a spray has been proposed as an alternative method of CHX delivery to the oral cavity. The aim of this study was to investigate the plaque inhibitory effects of CHX, cetylpyridinium chloride (CPC), and triclosan (TRN) delivered by sprays and mouthrinses. METHODS: The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 15 healthy volunteers in a 4-day plaque regrowth model. Products being tested (0.2% CHX, 0.12% CHX, 0.05% CPC, and 0.03% TRN) were used both as sprays and mouthrinses. A saline solution served as a negative control. On day 1, subjects received p…
