•Selective detection of NO2 with MOX sensors with specific filters.•Specific filters for O3 trapping.•Functionalized nanoporous materials doped with indigo carmine for the selective trapping of ...O3.•Hydrophobicity character of the nanoporous matrix which brings to the filter the resistance to humidity.
Specific filters can be used up-stream with metal oxide (MOX) gas sensors to trap ozone and allow the selective detection of NO2. These filtering media are based on nanoporous matrices doped with indigo-carmine that reacts selectively with O3. The nanoporous materials, produced via the sol-gel process using functionalized silicon alkoxides as precursors, are tailored for the trapping of O3. Depending on the nature of the filter, it is possible to entirely trap O3 and allow NO2 to partially pass over a certain range of concentration. For air depollution purpose, selected filters that efficiently trap both O3 and NO2 were exposed to harsh conditions under high concentrations of O3 (350–475 ppb) and humidity (RH: 72%, T = 21 °C). Their trapping efficiency and lifetime are determined and compared with those of activated carbon.
The Worldwide LHC Computing Grid relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any ...network issues, including connection failures, congestion, traffic routing, etc. The WLCG Network and Transfer Metrics project aims to integrate and combine all network-related monitoring data collected by the WLCG infrastructure. This includes FTS monitoring information, monitoring data from the XRootD federation, as well as results of the perfSONAR tests. The main challenge consists of further integrating and analyzing this information in order to allow the optimizing of data transfers and workload management systems of the LHC experiments. In this contribution, we present our activity in commissioning WLCG perfSONAR network and integrating network and transfer metrics: We motivate the need for the network performance monitoring, describe the main use cases of the LHC experiments as well as status and evolution in the areas of configuration and capacity management, datastore and analytics, including integration of transfer and network metrics and operations and support.
To compare the effects of active range of motion versus neuromuscular electrical stimulation superimposed to active range of motion on the range of motion recovery at the proximal interphalangeal ...joint following sprain.
Twenty patients in need of physical therapy to recover proximal interphalangeal range of motion participated voluntarily. Ranges of motion at the proximal interphalangeal joint were measured before and after each treatment with a finger goniometer.
Both treatments allow recuperation of the range of motion on the proximal interphalangeal joint. Moreover, the effectiveness of the superimposed technique in improving the range of motion is significantly better than that observed after active range of motion on its own.
These findings highlighted the superimposed technique as an effective method, which could be integrated in rehabilitation protocols for recovering the proximal interphalangeal joint range of motion following sprain.
Comparer les effets de la mobilisation active volontaire à ceux de l’électrostimulation neuromusculaire surimposée à la mobilisation active volontaire sur la récupération des amplitudes de l’articulation interphalangienne proximale suite à une entorse.
Vingt sujets nécessitant une prise en charge kinésithérapique pour récupérer la mobilité de l’articulation interphalangienne proximale ont participé volontairement à cette étude. Les amplitudes articulaires ont été mesurées avant et après chaque traitement avec un goniomètre à doigt.
Chacun des deux traitements permet de récupérer les amplitudes articulaires de l’articulation interphalangienne proximale. En outre, l’efficacité de la technique surimposée est significativement supérieure à celle de la mobilisation active volontaire pour récupérer les amplitudes articulaires.
La technique surimposée participe à une meilleure récupération des amplitudes articulaires et pourrait être intégrée aux protocoles de rééducation des entorses de l’articulation interphalangienne proximale de la main.
