F. F. F. F.—2000 A.d
During World War I there was much lamentation over the "defects of the draft," and the word "shocking" was in frequent use with reference to the condition of a large proportion of men of military age. When, more recently, it became necessary again for society to interpose a shield of human lives between itself and disaster, its cerebral cells once more became agitated over the report that its y...
متن کاملEdward F. Adolph Distinguished Lecture: The remarkable anti-aging effects of aerobic exercise on systemic arteries.
Cardiovascular diseases (CVD) remain the leading cause of morbidity and mortality in modern societies, and advancing age is the major risk factor for CVD. Arterial dysfunction, characterized by large elastic artery stiffening and endothelial dysfunction, is the key event leading to age-associated CVD. Our work shows that regular aerobic exercise inhibits large elastic artery stiffening with agi...
متن کاملThe Aging Voice: an Acoustic, Electro Analysis of Male and F
This study examines the differences between young and old adult voices. Acoustic cues in voices that enable listeners to recognize a speaker’s vocal age are specified as well as acoustic cues that straightly indicate the speaker’s chronological age. Electroglottographic data were used to directly examine glottal behaviour in aging voices. We found a strong spectral attenuation of high frequenci...
متن کاملInjury prevention in an aging workforce - F Drennan, D Richey -Professional Safety - Sep 03.PDF
The US is in the middle of a workers compensation and healthcare crisis. If it were not for Sept 11 and its aftermath, the crisis would likely be on the front page of every newspaper. More than 40 million Americans are without health insurance. The impact of the unhealthy lifestyles and natural aging of 80 million Americans born between 1946 and 1964 must not be underestimated. Businesses and A...
متن کاملAging Wiener-Khinchin theorem and critical exponents of 1/f^{β} noise.
The power spectrum of a stationary process may be calculated in terms of the autocorrelation function using the Wiener-Khinchin theorem. We here generalize the Wiener-Khinchin theorem for nonstationary processes and introduce a time-dependent power spectrum 〈S_{t_{m}}(ω)〉 where t_{m} is the measurement time. For processes with an aging autocorrelation function of the form 〈I(t)I(t+τ)〉=t^{Υ}ϕ_{E...
