This dual approach for contrast enhancement also succeeded in overcoming fluctuations in illumination caused by the alternating current power source.
In both the arid and semiarid regions gilgai patterns of swells and depressions caused by the alternate swelling and contraction following wetting and drying of clay soils—have developed.
Gordon et al. (2012) suggested that the variability of Makassar Strait Throughflow is caused by the alternate building/dissipating of a freshwater plug in the western Sulawesi Sea and Java Sea that are related to ENSO-dominated variability in the South China Sea Throughflow.
Fluctuations at three frequencies are found to dominate in different wake regions; the highest frequency is caused by the alternate vortex shedding from the lateral vertical edges of the prism, while the lowest frequency is connected with an oscillation of the streamwise vorticity structures detaching from the free-end.
Further, the lithotomy position might increases the risk of OASIS by causing a greater pressure towards the sphincter during the expulsion of the infant compared with alternate positions.
Vortices are shed sequentially from alternate sides of the cylinder, causing the cylinder to oscillate.
Rust fungi such as wheat stem rust can be carried between hosts by wind currents, and the parasite Schistosoma mansoni, which causes the disease schistosomiasis, alternates between Biomphalaria snails and humans by moving through water.
The inhibitory interactions that cause the percept to alternate between the two eyes' views operate on these temporally coarse form representations (as clearly suggested by Experiment 2 and 3).
Two secondary processes also are involved: (1) case hardening of steep, bare limestone surfaces by recrystallization caused by alternate wetting and drying, so that walls or knifelike edges result from weathering, and (2) continuous subsoil solution, if surfaces are nearly horizontal and runoff is diminished.
The pumping of the heart, or the heartbeat, is caused by alternating contractions and relaxations of the myocardium.
