The Panel on Plant Health performed a listing of non-EU viruses and viroids (reported hereinafter as viruses) of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L. and Vitis L. A systematic literature review identified 197 viruses infecting one or more of the host genera under consideration. Viruses were allocated into three categories (i) 86 non-EU viruses, known to occur only outside the EU or having only limited presence in the EU (i.e. reported in only one or few Member States (MSs), known to have restricted distribution, outbreaks), (ii) 97 viruses excluded at this stage from further categorisation efforts because they have significant presence in the EU (i.e. only reported so far from the EU or known to occur or be widespread in some MSs or frequently reported in the EU), (iii) 14 viruses with undetermined standing for which available information did not readily allow to allocate to one or the other of the two above groups. Comments provided by MSs during consultation phases were integrated in the opinion. The main knowledge gaps and uncertainties of this listing concern (i) the geographic distribution and prevalence of the viruses analysed, in particular when they were recently described; (ii) the taxonomy and biological status of a number of poorly characterised viruses; (iii) the host status of particular plant genera in relation to some viruses. The viruses considered as non-EU and those with undetermined standing will be categorised in the next steps to answer a specific mandate from the Commission to develop pest categorisations for non-EU viruses. This list does not imply a prejudice on future needs for a pest categorisation for other viruses which are excluded from the current categorisation efforts. (C) 2019 European Food Safety Authority.

Department of Chemistry, Government College, Burner, Barmer-344 001 Manuscript received 11 October 1982, revised 26 May 1986, accepted 18 June 1986 The mixed-ligand complexes of InIII with L-glutamate and L-methionine/L-valise/ L-proline have been investigated by polarographic technique. The cathodic reduction of mixed complexes involved three electrons, reversible and diffusion-controlled step. The logarthmic values of over all formation constants of In(L-glutamate)(L-methinni­nate), In(L-glutamate)(L-valinate) and In(L-glutamate)(L-prolinate) complexes were 16.78, 17.19 and 18 00, respectively. The positive values of logritham of mixing constant revealed that the mixed complexes were more stable than the parentbis­complexes.

Given a Banach space X, we say that a sequence {xn} in the unit ball of X is L-orthogonal if ∥x+xn∥→1+∥x∥ for every x∈X. On the other hand, an element x∗∗ in the bidual sphere is said to be L-orthogonal (to X) if ∥x+x∗∗∥=1+∥x∥ for every x∈X. The aim of this paper is to clarify the relation between L-orthogonal sequences and L-orthogonal elements. Namely, we study whether every L-orthogonal sequence contains L-orthogonal elements in its weak*-closure. We provide an affirmative answer whenever the ambient space has small density character. Nevertheless, we show that, surprisingly, the general answer is independent of the usual axioms of set theory. ; This work was supported by the Government of Spain, AEI/FEDER, EU [MTM2017-86182-P]; the Fundación Séneca, ACyT Región de Murcia [20797/PI/18]; the European Social Fund; the Youth European Initiative under the Spanish Séneca Foundation [21319/PDGI/19 to G.M.C.]; the Juan de la Cierva-Formación fellowship [FJC2019-039973/ AEI / 10.13039/501100011033 to A.R.Z.]; the Spanish AEI Project [PGC2018-093794-B-I00 / AEI / 10.13039/501100011033 (MCIU/AEI/FEDER, UE) to A.R.Z.]; and the Junta de Andalucía [A-FQM-484-UGR18 and FQM-0185 to A.R.Z.].
