This article investigates the feasibility of using a simplified approach, based on measurement power ratio parameters, for harmonic emissions assessment at point common coupling (PCC). The proposed approach comes from concept factor correction and definitions IEEE Std. 1459-2010, where line utilization pollution levels are evaluated by means ratios between quantities apparent decomposition. In ...

The Asian citrus psyllid (ACP, Diaphorina citri, Hemiptera: Liviidae), is the principal vector of the phloem-limited bacteria strongly associated with huanglongbing (HLB), the world's most serious disease of citrus. Host plant resistance may provide an environmentally safe and sustainable method of controlling ACP and/or HLB. Two xCitroncirus accessions (hybrids of Poncirus trifoliata and Citru...

Chandra observations of the supermassive black hole in the nucleus of IC 1459 show a weak (LX=8×10erg s−1, 0.3-8 keV), unabsorbed nuclear X-ray source, with a slope Γ = 1.88±0.09, and no strong Fe-K line at 6.4 keV (EW<382 eV). This describes a normal AGN X-ray spectrum, but lies at 3×10−7 below the Eddington limit. The SED of the IC 1459 nucleus is extremely radio loud compared to normal radio...

Since the penetration of photovoltaic systems in the electrical network is increasing, the need to register and model the contribution of these energy sources, in terms of generated disturbances, quality and amount of available power, is becoming a crucial issue for optimal management of grid. So, this paper, starting from data experimentally recorded on a medium scale photovoltaic system that ...

We analyse long–slit spectra of four early–type galaxies which extend from ∼ 1 to ∼ 3 effective radii: IC 1459, IC 3370, NGC 3379 and NGC 4105. We have extracted the full line–of–sight velocity distribution (in the case of NGC 3379 we also used data from the literature) which we model using the two–integral approach. Using two–integral modelling we find no strong evidence for dark haloes, but t...
