In settings where microscopy was not available, however, using rapid diagnostic tests led to a significant reduction in the overprescription of antimalarials, without any evidence of clinical harm, and to better targeting of antibiotics. Trial registration ClinicalTrials.gov NCT00493922.
Carbide (or more specifically tungsten carbide and titanium carbide) is a very common material on any sort of cutting tool: For example, saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide.
These kinds of saws can also be used (with the proper blade) on metals, plastic, and ceramics. Features to look for on a jig saw include variable speeds, an orbital blade motion, a laser line, dust blowers, and lights to illuminate your cut. Again, this kind of saw comes in either a battery powered or corded models.
