One strategy for discriminating between explosions and natural events depends on accurate determinations of event locations, including focal depths. If a seismic event could be reliably determined to have a focal depth greater than a few kilometers, one could be confident that the event is not an explosion. But to determine focal depths accurately, one must first have a fairly accurate model of...

Lubricant selection and cleaner chemistry is oftentimes one of the most overlooked parts of industrial metal processing. Their selection can affect not only the ability to adequately clean parts; it can also potentially affect the success of a waste minimization effort to recycle the cleaner. Certain lubricants are more compatible with certain cleaning processes than others. This paper will dis...

We developed a new technique of inverting short-period (0.5–2 Hz) P waveforms for determining small earthquake (M 3.5) focal mechanisms and moments, where magnitude 4 events with known source mechanisms are used to calibrate the “unmodeled” structural effect. The calibration is based on a waveform cluster analysis, where we show that clustered events of different sizes, for example, M 4 versus ...

Autograft is considered ideal for grafting procedures, providing osteoinductive growth factors, osteogenic cells, and an osteoconductive scaffold. Limitations, however, exist regarding donor site morbidity and graft availability. Although allograft provides an osteoconductive matrix with some osteoinductivity, its availability is limited. To achieve optimal bone graft properties, researchers ar...

Cannabinoid compounds include phytocannabinoids, endocannabinoids, and synthetics. The two primary phytocannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), with CB1 receptors in the brain and peripheral tissue and CB2 receptors in the immune and hematopoietic systems. The route of delivery of cannabis is important as the bioavailability and metabolism are very different f...

Since the early 1990s, with changing market conditions and the opening up of its borders and markets to global tourism, commerce and trade, South Africa has become an attractive market for long-distance drug trafficking and has seen an increase in the activities of international drug syndicates. In general, the Southern African region became exposed to drugs previously rarely available on the m...

Tetranychus urticae Koch, is known as a two-spotted spider mite and the most obtrusive polyphagous non-insect pest that causes havoc on horticultural crops. Cucumber cultivation threatened by variety of infestations, among which mites cause damage to crop. The efficiency six different chemical acaricides against T. in cucumber grown polyhouse was examined. results acaricide evaluation trial rev...
