This means that the Earth's liquid outer core absorbs these waves and creates a shadow on the opposite side of the Earth from the epicenter where no s-waves are detected. S-waves are longitudinal, which means they travel perpendicular to the direction of the wave's path. Think about how ...
Physics, on the other hand, defines sound as a vibration that travels as an acoustic wave through a transmission medium such as liquid, gas, or as longitudinal and transverse waves in solids. Sound is the feedback of such waves and their interpretation by the brain in human physiology and...
A dose reduction of lithium of about 20% is often required in elderly patients compared to younger patients. However, for maintenance monotherapy in OABD lithium is effective and well tolerated and it still represents the preferred choice, if correctly used. However, special caution is required to...
Lastly, the tiger crane fly belongs to theGenus Nephrotoma. This genus is known for its distinct tiger-striped pattern found on the wings and abdomen, which serves as a camouflage in their natural habitat. Other features of Nephrotoma species include: Bold, longitudinal stripes on the thorax S...
Crazy But True Facts about the Pacific Ocean If you put the entire land surface of the Earth together, the Pacific Ocean would still be bigger. Its greatest longitudinal extent (the distance it covers according to the lines of longitude) measures about 12,000 miles (19,312 km) between ...
The Families and Childhood Transitions Study (FACTS) is a multidisciplinary longitudinal cohort study of brain development and mental health, with two waves of data collection currently funded, occurring 18-months apart, when child participants are aged approximately 8- and 10-years old. Methods/...
The Kalahari Desert is located in southern Africa, and covers parts of the countries of Namibia, Botswana and South Africa. The landscape of the Kalahari is characterized by vast savannas of red sand, longitudinal dunes, and a lack of surface water. Dotted throughout the landscape are “kopje...
Gravitational wave, the transmission of variations in the gravitational field as waves, first directly observed in 2015.
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of
Two waves of a longitudinal survey from 1996 to 1999 in rural Kenya are analyzed using fixed-effects regression. Social support for each function of condom use is measured with indicators of the proportion of individuals in the peer group that use condoms for a particular purpose or have a ...
