The coupling efficiency of a phased multi-waveguide structure (the "Grill") designed to launch HF-waves at the lower hybrid resonance heat large toroidal plasmas, while satisfying accessibility condition, is studied. To find reflection and transmission coefficients, as well k||-spectrum excited field, waveguide represented superposition eigenmodes, matched field in plasma, which evaluated on assumption linear density profile near plasma edge.

Feedback-controlled puffing of neon and deuterium has been applied to control the edge-localized-mode behavior target plate power deposition during high-power $H$-mode discharges in ASDEX Upgrade. A regime found which more than 90% heating is lost through radiation divertor detachment occurs, without deterioration energy confinement. The plasma remains $H$ mode, exhibiting small-amplitude, high-frequency ELM's, do not penetrate plates strike zone region.
ASDEX Upgrade has recently finished its transition towards an all-W divertor tokamak, by the exchange of last remaining graphite tiles to W-coated ones. The plasma start-up was performed without prior boronization. It found that large He content in plasma, resulting from DC glow discharges for conditioning, leads a confinement reduction. After change D inter-shot quickly dropped and, parallel, usual H-Mode with H factors close one achieved. initial conditioning phase, oxygen concentrations...

Hepatitis E virus (HEV) is an emerging causative agent of acute hepatitis worldwide. To provide insights into the epidemiology HEV in Italy, a large-scale investigation was conducted urban sewage over nine years (2011–2019), collecting 1374 samples from 48 wastewater treatment plants located all 20 regions Italy. Broadly reactive primers targeting ORF1 and ORF2 were used for detection typing HEV, followed by Sanger next generation sequencing (NGS). Real-time RT-qPCR also to attempt...
Tungsten-coated tiles, manufactured by plasma spray on graphite, were mounted in the divertor of ASDEX Upgrade tokamak and cover almost 90% surface facing strike zone.

Early diagnosis of subclinical ketosis is fundamental in the production management dairy cattle. Without evident clinical signs, this pathological condition causes important economic losses for farmer and significant health repercussions cattle that could develop an altered immune function. Laboratory techniques, although accurate, are expensive, invasive, cannot be used real-time monitoring entire herd. On contrary, analysis volatile organic compounds (VOCs) contained breath affected by...
The optimal management of cattle nutrition promotes animal health and welfare, increases livestock farms’ productivity competitiveness, enhances environmental sustainability practices. Animal feeding operations play a crucial role as many factors can drive the theoretical ration formulated by nutritionists far from one animals ingest. Precision technologies (e.g., NIR sensors on milling cutter chopper-mixer wagon; computer vision systems installed in mixing tank) may allow for accurate...
Ammonia, methane, and carbon dioxide are the primary atmospheric emissions from cattle pig farms. Asignificant part of these is produced by decomposition slurry organic matter during manure storage andtreatment phases.
