For many other roses, however, the seeds must be refrigerated for about four weeks at about 40 degrees, for what gardeners call stratification, a cold period, and again for about four months, at a somewhat higher temperature, for germination, with a light on in the refrigerator.
Over the silica support there is a slight stabilisation of the conversion as it occurs at a somewhat higher temperature than that observed with the bulk material ~18 °C.
Although the exact temperature range for this heat sensitivity has not been determined, prolonged exposure to temperatures in the range 100 150 °C and possibly somewhat higher temperature, should be avoided.
According to astronomer Daniela Calzetti of the Space Telescope Science Institute in Baltimore, Maryland, NICMOS is between 30% and 40% more sensitive than it used to be--thanks to a new coolant, it operates at a somewhat higher temperature, increasing the efficiency of the detectors.
The experimental phenomenon, that the alloys containing more detrimental constituents but aged at a somewhat higher temperature exhibit ductility and fracture toughness superior to those of the alloys containing less detrimental constituents but aged at lower temperatures, could be reasonably explained by the cooperative effect of the heat treatment steps.
In patients with high EA activity functional parameters were similar on admission to the other EA stratification groups except for a somewhat higher temperature.
Fats are usually solid at ordinary temperatures, such as 25 °C (77 °F), but they begin to liquefy at somewhat higher temperatures.
At somewhat higher temperatures, the rock would become an amphibolite, reflecting a mineralogy composed predominantly of the amphibole hornblende along with plagioclase and perhaps some garnet.
Somewhat higher temperatures are obtained using other methods.
Epitaxial TiC films with a good quality have been deposited at temperatures as low as 100°C with metal sputtering, while somewhat higher temperatures (>200°C) are required for the other metals.
Thorium oxide (or thoria) alloy electrodes were designed for DC applications and can withstand somewhat higher temperatures while providing many of the benefits of other alloys.
