But our research, published Wednesday in Nature, pushes back the timing of this event to at least 65,000 years ago.

The radiation causes charge to remain within the grains in structurally unstable "electron traps".The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried.Research has primarily focused on debris impact loading and less emphasis has been placed into quantifying the loads and effects associated with debris damming, which occurs when solid objects accumulate at the front of structures.The formation of the debris dam has been shown to results in increased drag forces, backwater rise, and flow accelerations which can influence the stability of the structure.Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating.

It is useful to geologists and archaeologists who want to know when such an event occurred.Additionally, the study examined the influence of the blockage ratio on the backwater rise as well as the drag coefficient.Full article Cua Dai is one of the major estuarine areas in Central Vietnam that plays a significant role in local maritime transport, fisheries, and tourism activities.It uses various methods to stimulate and measure luminescence It includes techniques such as optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and thermoluminescence (TL)."Optical dating" typically refers to OSL and IRSL, but not TL.This event was remarkable on many fronts, as it represented the largest maritime migration yet undertaken, the settlement of the driest continent on Earth, and required adaptation to vastly different flora and fauna.
