Gas and Mode, Vertical and Rotational Effects with a Three Piston Gauge Apparatus
Autor: James W. Schmidt, B E Welch, Charles D. Ehrlich
Publikováno v: Metrologia. 30:599-602
A semi-automated three piston gauge apparatus has been used to measure gas species and mode effects in a low pressure pneumatic dead-weight piston gauge. Two gases, He and N2, were used in both gauge and absolute modes, as well as several "intermedia

Accounting for the effects of gas species on piston gauge calculated area: absolute mode
Autor: B E Welch, F E Jones
Publikováno v: Journal of Physics E: Scientific Instruments. 22:981-985
A model has been developed, and tested experimentally, to account for the apparent dependence of the effective cross-sectional area of pistons in gas-piston-gauge pressure standards on the particular gas with which the gauge is operated, in the absol

Effects of viscosity, temperature, and rate of rotation on pressure generated by a controlled‐clearance piston gauge
Autor: J K N Sharma, K. Jain, Vern E. Bean, Ruben J. Lazos, B. E. Welch
Publikováno v: Review of Scientific Instruments. 55:563-569
The calculation of the pressure generated by a controlled‐clearance piston gauge depends upon the jacket pressure corresponding to zero clearance between the piston and cylinder Pz. The dependence of Pz on the viscosity of the pressure transmitting

The Mercury Melting Line Up to 1200 MPa
Autor: J Houck, B. E. Welch, G F Molinar, V E Bean
Publikováno v: Metrologia. 16:21-29
The mercury melting line has been determined for pressures up to 1200 MPa. The change of electrical resistance in the mercury sample was used for detecting the equilibrium between the solid and liquid phases. Pressure measurements were made with high

Pressure and temperature measurements in the annulus between the piston and cylinder of a simple dead‐weight piston gauge
Autor: B. E. Welch, Vern E. Bean
Publikováno v: Review of Scientific Instruments. 55:1901-1909
Precise and accurate pressure measurements are obtained using appropriately designed and operated piston gauges. Elastic distortion of the piston and cylinder is the leading cause of inaccuracy in measurement of higher pressures. The distortion depen

Relationships of Body Fat to Motor Fitness Test Scores
Autor: C. E. Crisp, R. P. Riendeau, L. V. Crowley, J. E. Brockett, P. E. Griffin, B. E. Welch
Publikováno v: Research Quarterly. American Association for Health, Physical Education and Recreation. 29:200-203
The purpose of this study was to examine the relationships between per cent body fat and selected motor fitness tests. Significant negative correlations of from −0.29 to −0.68 were found between per cent body fat and the selected motor fitness te

Metabolic Interrelationship between Folic Acid, Vitamin B12, and the Citrovorum Factor
Autor: J. R. Couch, B. E. Welch, Sabit Gabay, R. W. Perrett, V. M. Doctor, C. L. Brown
Publikováno v: Experimental Biology and Medicine. 84:29-32
SummarySupplementing a low vit. B12-PGA chick diet with either increasing levels of vit. B12 (30 γ and 500 γ/kg) or increasing levels of PGA (2, 100, and 400 mg/kg) resulted in an increased capacity by the liver homogenates to convert added PGA to

Effect of the Level of Expiration on Body Density Measurement
Autor: C. E. Crisp, B. E. Welch
Publikováno v: Journal of Applied Physiology. 12:399-402
This experiment was designed to test the reproducibility of body density measurements following maximum and approximately one-half maximum expiration. A total of 26 adult males were tested. Duplica...

Oxygen-tolerant Strain of Chlorella sorokiniana
Autor: Fred W. Wagner, B. E. Welch
Publikováno v: Applied Microbiology. 17:139-144
An oxygen-tolerant strain (OTS) of Chlorella sorokiniana was isolated by growing and continuously subculturing the oxygen-sensitive strain (OSS) in growth medium bubbled continuously with 95% O 2 -5% CO 2 . Under these conditions, 6 to 8 hr were requ
