Achilles\u27 heel of Grapevine Downy Mildew - The Contractile Vacuole as Target for Potential Control Strategies in Viticulture [PDF]
Downy Mildew (DM) is a major disease in viticulture since the 19th century, caused by the plant parasitic oomycete Plasmopara viticola, which has algal ancestors.

Is the cluster of galaxies "Abell 194" surrounded by an Einstein-Straus vacuole? [PDF]
It is suggested that an ``Einstein-Straus vacuole'' -- a region of space time with a metric obtained by solving the equations of general relativity of a mass condensation in an expanding universe with vanishing cosmological constant -- surrounds the cluster of galaxies ``Abell 194''.

Periacineta mexicana n. sp. (Ciliophora, Suctoria, Discophryida), Epizoic on Mexican Backswimmers of the Genus Buenoa (Insecta, Hemiptera, Notonectidae) [PDF]
A new species of suctorian in the genus Periacineta, epibiotic on aquatic bugs (Hemiptera, Heteroptera, Nepomorpha), is described on the basis of morphological characteristics of the cell body, lorica, tentacular placement, and stalk, and its 18S rRNA ...

The Vacuole Model: New Terms in the Second Order Deflection of Light [PDF]
The present paper is an extension of a recent work (Bhattacharya et al. 2010) to the Einstein-Strauss vacuole model with a cosmological constant, where we work out the light deflection by considering perturbations up to order M^3 and confirm the light bending obtained previously in their vacuole model by Ishak et al. (2008).

Rab11-like GTPase associates with and regulates the structure and function of the contractile vacuole system in \u3ci\u3eDictyostelium\u3c/i\u3e [PDF]
Screening of a cDNA library revealed the existence of a Dictyostelium cDNA encoding a protein 80% identical at the amino acid level to mammalian Rab11.

The riddle of the plant vacuolar sorting receptors [PDF]
Proteins synthesized on membrane-bound ribosomes are sorted at the Golgi apparatus level for delivery to various cellular destinations: the plasma membrane or the extracellular space, and the lytic vacuole or lysosome. Sorting involves the assembly of vesicles, which preferentially package soluble proteins with a common destination.

More on Lensing by a Cosmological Constant [PDF]
The question of whether or not the cosmological constant affects the bending of light around a concentrated mass has been the subject of some recent papers. We present here a simple, specific and transparent example where $\Lambda$ bending clearly takes place, and where it is clearly neither a coordinate effect nor an aberration effect.
