The Catalyst 3750 switches and the Cisco EtherSwitch service modules support stacking through Cisco StackWise technology. The Catalyst 3560, 2970, and 2960 switches do not support switch stacking. Unless otherwise noted, the term switch refers to a standalone switch and to a switch...
In its general purport, the term prebiotic refers to compounds or processes that are robust, energetically not excessively demanding, based on commonly available starting materials. Nucleosides can be obtained through de novo synthesis by the oxazoline chemistry15,16,17 or by the formamido pyrimidine...
The Catalyst 3560 and 2960 switches do not support switch stacking. Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack. These release notes include important information about Cisco IOS Release 12.2(46)SE and later and any limitations, restri...
If we do this on Mars, energy from the sun might be used as a catalyst (催化剂). The idea will also make space travel more eco-friendly. “If the CO2-based fuel could be used in a rocket launch, we could pr...
PURPOSE: To obtain a cordierite structure which has a low coefft. of thermal expansion, excellent thermal impact resistance and orientation characteristics, etc., and is adequate for a catalyst support, etc., by molding a cordierite forming batch mixture having a specific compsn. to a structure...
The present study refers to the use of an environmental pollutant generated during the removal of hexavalent chromium from aqueous media. This pollutant is a material with catalytic properties suitable for application in the oxidative degradation of prob
The first step of pyrimidine synthesis along the orotate pathway is studied to test the hypothesis of geochemical continuity of protometabolic pathways at the origins of life. Carbamoyl phosphate (CP) is the first high-energy building block that interven
