Self-grafting a simple method for vegetative propagation of apple clonal rootstocks

A simple method for measuring erythrocyte deformability.

To pass through the microcirculation red blood cells (RBCs) need to undergo considerable deformation. The increased rigidity of older cells is probably the main cause of their selective trapping by the spleen; and indirect evidence suggests that impaired deformability may be a critical factor in causing diminished peripheral blood flow (Chien et al, 1967; Schmid-Schonbein et al, 1969; Weed, 197...

Airline Departure Delay Prediction

As any frequent flier is no doubt aware, flight delays and cancellations are a largely inevitable part of commercial air travel. In the past ten years, only twice have more than 80% of commercial flights arrived on-time or ahead of schedule. Punctuality is an issue for all major carriers, with some struggling more than others: through September 2008, American Airlines flights were on time just ...
