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.
Often, carbide is used to exterminate moles, and the store attendant can help you locate it as such. How one uses carbide to kill moles is left to the imagination. If this fails, attempt to locate a welding supply store.
