An important piece of Latin America's artistic history lies anonymously in five metal containers exposed to moisture, rust and temperature changes in a storage lot a few miles outside this city.
Five governing parameters are selected, i.e. the water content, mass of sulfurized rust, operating temperature, air flow rate and oxygen concentration in the respiratory/safety valve.
This study suggests the use of the following measures: for abnormal conditions such as pipeline cracking/damage or rusting, high-temperatures caused by material leakage into the inner protective layer of pipelines should be prevented.
However, the rust cannot survive temperatures below 10C.
To screen for leaf rust resistance under low temperature conditions, one week old seedlings were inoculated with P. triticina pathotype 104 1,2,3,(6),(7),11 and incubated for 24 hrs at 20°C and high humidity before being moved to a growth cabinet set at a 10°C constant temperature and 16 hrs photoperiod.
The effect of temperature on yellow rust resistance genes is well-known (reviewed in [ 5]).
Future work is needed to confirm the presence of ferrosic hydroxides or natural green rusts in actively venting low temperature sulfur-free springs by collecting samples of the associated iron hydroxide material in anaerobic chambers.
Scientists suspect warmer temperatures have helped the rust spread, but they do not have any evidence to show that this is the case.
In Nicaragua, rising temperatures are spreading "coffee rust fungus", a disease which is killing thousands of trees and may render 80% of its the nation's coffee-growing areas unusable by 2050.
Using heavy gauge stainless steel for the fire box "floor" will give better results, since it is more resistant to high temperatures and will not rust out over time.
Several attempts to induce a resistance response to leaf rust in seedlings when grown at low temperature failed in RL6077.
