Gold has both private uses (depletion uses and service uses) and government uses. It can be obtained from mines with high extraction costs (about $300 per ounce) or from aboveground stocks with no extraction costs. Governments still store massive stocks of gold. Making government gold available for private uses through some combination of sales and loans raises welfare from private uses by remo...

The vocal tract resonances of trained soprano singers were measured while they sang a range of vowels softly at different pitches. The measurements were made by broad band acoustic excitation at the mouth, which allowed the resonances of the tract to be measured simultaneously with and independently from the harmonics of the voice. At low pitch, when the lowest resonance frequency R1 exceeded f...

He was operated on on 2nd March, 1932, by the suprapubic method and 12 stones weighing 3 ounces were removed. Litholapaxy was not done because the man was very old and had bad cystitis. The largest number of stones so far removed is 9, according to Nelson's loose leaf surgery, while in this case 12 fair sized stones were removed. They were all smooth and faceted (see figure). The laboratory rep...

Associations have been found between birth weight and many diseases in adult life. In most countries, few birth records exist for older adults; therefore, birth weight is usually obtained by maternal recall or self-report. This study examined determinants of the availability and accuracy of self-report in middle-aged and elderly women. Birth weights, recorded at the time of birth, were found in...

Actual relationships of human size to strength have remained undetermined despite decades of research by many investigators because the determination necessitates valid theoretical formulation and selection through three essential criteria of a proper sample of subjects for empirical testing. The formula is: Vol.(Wt.) strength e k Rt. Champion weightlifters satisfy all criteria, and, by minor a...

We proposed a design for a LASER pico-projector with a low speckle contrast value and high contrast ratio that maintains system efficiency. The method for speckle contrast reduction utilizes two diffusers and a Voice Coil Motor (VCM) oscillator. The two different diffusers for a high contrast ratio and high system efficiency can be divided into two categories. In Category 1, the speckle contras...

Utterances of two adults males were analyzed and synthesized by a fast Fourier Transforms method. Each of the two voices was synthesized in each of the twenty-seven combinations of three levels each of rate, mean FO, and variance of FO (a total of fifty-four "voices" generated from two). The effects of the rate, mean FO, and variance of FO manipulations, the interactive effects of rate and vari...

BACKGROUND Research on cannabis use has emphasized frequency as a predictor of problems. Studies of other drugs reveal that frequency relates to psychological and physiological outcomes, but quantity also plays an important role. In the study of cannabis, quantity has been difficult to assess due to the wide range of products and means of consumption. METHODS The present study introduces thre...

21 st April, noon.?Half an ounce of madar juice was mixed with 8 ounces of milk and given to a puppy ; it drank only one mouthful; some more was forced down its throat ; perhaps half of the milk was swallowed. Shortly after taking the poison, saliva began to flow from its mouth. It seemed uncomfortable and restless ; power of motion and sensibility unaffected ; vomited once ; pupils natural. It...
