Introduction. cron is a UNIX tool that has been around for a long time, so its scheduling capabilities are powerful and proven. The CronTrigger class is based on the scheduling capabilities of cron.. CronTrigger uses "cron expressions", which are able to create firing schedules such as: "At 8:00am every Monday through Friday" or "At 1:30am every last Friday of the month".

Quartzite Versus Quartz and Marble . Quartzite is a metamorphic rock, while quartz is an igneous rock that crystallizes from magma or precipiates around hydrothermal vents. Sandstone under pressure becomes quartz arenite and quartzite, but quartzite does not become quartz. The construction industry further complicates the matter.

Horizontal GaN nanowires were grown on quartz substrates by the VLS method in a chemical vapor deposition (CVD) system, consisting of a quartz tube that was placed inside a three-zone tube furnace. The nitrogen source was NH 3 gas; H 2 was used as a carrier gas, and the pressure in the fused silica tube was held at 400 mbar during the synthesis.
