CHANGE IN BLOOD PRESSURE AND TOTAL CHOLESTEROL WITH RETIREMENT
American Journal of Epidemiology, 1984This study examines change in systolic blood pressure, diastolic blood pressure, and total serum cholesterol over a three-year span in two groups of men aged 55-74 years at follow-up: 1) 262 men who were working at baseline but retired at follow-up, and 2) 409 age peers who remained employed at both measurement times.

Journal of the Aeronautical Sciences, 1956
When a total pressure probe is used for measuring flows with transverse total pressure gradients, a displacement of the effective center of the probe toward the higher total pressure is sometimes observed. This paper gives the results of an investigation of the effect for certain transverse cylindrical and forward facing (or pitot type) total pressure ...

Pressurized Cement Fixation in Total Hip Arthroplasty
Clinical Orthopaedics and Related Research, 1988In a follow-up study of 108 total hip arthroplasties, the 92% excellent and good results after seven to 11 years of implantation are evidence in support of cement fixation. The precision of the cementing technique is essential for a high percentage of successful results after ten or more years.

Absolute Total Vapor Pressure of Gallium Dichloride
Journal of Chemical & Engineering Data, 2010The total vapor pressure of gallium dichloride was determined by the torsion method over the temperature range of (372 to 441) K, and its temperature dependence was represented by the equation log(p/Pa) = (14.23 +/- 0.30) - (5829 +/- 00)/(T/K). From this equation the second-law sublimation enthalpy of a mole of gaseous mixture was derived as Delta(sub ...

Developments in the measurement of total and partial pressure
Vacuum, 1986Abstract Clean vacua down to the 10 −8 Pa range can be produced without difficulty if such conditions are neede (e.g. for surface science studies). Limiting pressures of the order of 10 −5 Pa are sufficient in the majority of industrial systems. Except in special cases the reproducibility of the vacuum measurement is often more important than the ...

Intrafemoral Pressure in Total Hip Replacement
1990Intra-operative trans-oesophageal two-dimensional echocardiography was used to measure the risk of increasing intrafemoral pressure during total hip replacement. This study describes aspects of hip arthroplasty more related to cementation technique than the interface.

Omegatron for Total and Partial Pressure Measurement
Journal of Vacuum Science and Technology, 1970Partly because of a supposed simplicity, omegatrons have been used frequently in applications requiring a light-weight or low-volume mass spectrometer. The present gauge was suggested by the Klopfer ionization gauge, which is similar to an omegatron in its electrode arrangement.

Comparison of Total Body Tissue Interface Pressure of Specialized Pressure-Relieving Mattresses
Journal of Long-Term Effects of Medical Implants, 2004The pressure-relieving ability of three specialized support surface mattresses was investigated and compared to a standard hospital mattress by measuring total body tissue interface pressure in a laboratory experiment designed to simulate clinical conditions predisposing to formation of pressure ulcers.Pressure ulcers are commonly seen in the elderly ...

The transient total pressure method: an analysis
Fluid Phase Equilibria, 1986Abstract The Transient Total Pressure Method is a combined experimental and data analysis method the purpose of which is to determine simultaneously the phase equilibria and kinetic behavior of chemical systems undergoing spontaneous chemical reactions. This paper presents further discussion of the method.
