The literature cites many alternative hosts of Phytophthora erythroseptica. However, evidence of host status is often insufficient, thus a polyphasic approach (morphological, molecular, histological and pathogenicity) is required. ABSTRACT Most published studies of Phytophthora erythroseptica, the major causal agent of pink rot of potato, have focused ...

Commodity risk assessment of Populus alba, Populus nigra and Populus tremula plants from the UK
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Populus alba, Populus nigra and ...

Modular Tunable α‐Helical Peptide Hydrogels for Neuronal Cells
Rationally designed peptides are used to alter the elastic properties of α‐helical hydrogels, to introduce adhesion peptides and growth factors, and to spatially pattern proteins. The modularity of the hydrogelating self‐assembling fiber (hSAF) system provides a flexible platform for manipulating primary neural cell behavior, with potential future ...

Molecular Gas in Elliptical Galaxies [PDF]
The distribution and kinematics of the molecular gas in elliptical galaxies give information on the origin and history of the gas and the rate of star formation activity in ellipticals. I describe some preliminary results of a survey which will more than double the number of elliptical galaxies with resolved molecular distributions.

Galaxy Merging and the Fundamental Plane of Elliptical Galaxies [PDF]
We present preliminary results of numerical simulations of dissipationless merging of stellar systems, aimed at exploring the consequences of merging between gas free, spheroidal systems. In particular, we study the dynamical and structural characteristics of hierarchical merging between equal mass stellar systems, and we compare the properties of the ...

Structure and Kinematics of Early-Type Galaxies from Integral Field Spectroscopy [PDF]
Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are expensive for large galaxy samples.

Dynamical Family Properties and Dark Halo Scaling Relations of Giant Elliptical Galaxies [PDF]
Based on a uniform dynamical analysis of the line-profile shapes of 21 mostly luminous, slowly rotating, and nearly round elliptical galaxies, we have investigated the dynamical family relations and dark halo properties of ellipticals.

Abstract The dynamics of giant planet magnetospheres is controlled by a complex interplay between their fast rotation, their interaction with the solar wind, and their diverse internal plasma and momentum sources. In the ionosphere, the Hall and Pedersen conductances are two key parameters that regulate the intensity of currents coupling the ...

SIMULATIONS OF LARGE-SCALE GASEOUS STRUCTURES WITH SPH
A computer programme based on the 3D SPH approach is described. Some numerical results are presented: the formation of gaseous ring around an SO galaxy due to the stripping of a gas-rich donor system.

Dynamical Models of Spherical Galaxies with Massive Halo [PDF]
Using the Schwarzschild's linear programming technique, we obtained the general solutions of the collisionless Bolzmann equation describing the spherical galaxy in dynamical equilibrium.
