Salad savoy (Brassica oleracea L.) is a vegetable crop that is becoming a valued addition to fresh-cut salad mixes. This study was conducted to develop a modified atmosphere packaging system for fresh-cut salad savoy and to evaluate the effect of film oxygen transmission rate (OTR) on package atmospheres, and consequently product quality changes during storage. Two varieties of salad savoy (whi...

[1] Valley networks appear to be cut by liquid water, yet simulations suggest that early Mars could not have been warmed enough by a CO2-H2O greenhouse to permit rainfall. The vulnerability of an early atmosphere to impact erosion, the likely rapid scavenging of CO2 from the atmosphere by weathering, and the lack of detection of weathering products all support a cold early Mars. We explore the ...

The many low energy modes near a black hole horizon give the thermal atmosphere a divergent entropy which becomes of order A/4G with a Planck scale cut-off. However, Sorkin has given a Newtonian argument for 3+1 Schwarzschild black holes to the effect that fluctuations of such modes provide the horizon with a non-zero quantum mechanical width. This width then effectively enforces a cut-off at m...
