Bulb Firmness of Hybrid Onions

Stop the Rot! Using Cultural Practices to Reduce Bacterial Bulb Decay in Onions

Narrow plant spacing reduced bacterial bulb decay by 53 to 64% Do you know how easy this is? A simple modification to adjust your planting configuration is all it would take to drastically reduce losses from bacterial bulb decay. Our studies showed that when plant spacing was reduced from 6 or 8 inches to 4 inches with 3 or 4 rows per 3-foot plastic mulch bed (row spacing: 4 rows = 6 inch; 3 ro...

Equilibrium Onions ?

– We demonstrate the possibility of a stable equilibrium multi-lamellar (“onion”) phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvature modulus. The onion phase is stabilized by non-linear elastic moduli coupled to a polydisperse size distribution (Apollonian packing) to allow space-filling without appreciable elastic distortion. This model is comp...

Unions of Onions

Let D be a set of n pairwise disjoint unit disks in the plane. We describe how to build a data structure for D so that for any point set P containing exactly one point from each disk, we can quickly find the onion decomposition (convex layers) of P . Our data structure can be built in O(n log n) expected time and has linear size. Given P , we can find its onion decomposition in O(n log k) time,...
