The overall power of the enforced oscillations shows a typical resonance behaviour around the natural, free running frequency. The intriguing observation that external temperature jump rhythms lead to resonance, not only of the basic oscillation but also of its harmonic overtones, is discussed in ...
it’s only natural to wonder why. Maybe you’re the only woman in your family who gets severe cramps. Maybe your painful periods didn’t start until your 20s. Some period pain is normal for most, but if your pain is very severe, it may be caused by an underlying condition. ...
Servo-vibrograph of Long Natural Period When a pendulum type vibrograph is used in measuring vibration, the longest measurable period is determined by the natural period of the pendulum. Therefore when the measured vibration is supposed to have a long period component, the nat... Kozo MATSUSHIMA...
7.2.11.4 Natural Roll Period The ratio c/a is equal to the natural circular roll frequency squared: (7.33)ω02=ca=g · Δ · GMΔ · iT'2=g · GMiT'2 In the nautical field, it is practical to refer to the natural roll period, T0, of the ship. The period is...

Find the period and frequency of the pendulum. A string vibrates with standing waves in 5 loops when the frequency is 600 Hz. What frequency will cause the string to vibrate in only two loops? What is the frequency (in Hz) of the eardrum's vibration...

Evidence for natural selection We have examined the ratio of non-synonymous to synonymous substitutions in the Beringian GSPs to detect the impact of the Beringian Isolation Period on the efficacy of purifying selection. Table 2 tabulates the percentages of Non-synonymous and Synonymous substitutions...
