Rates of Unemployment and Penetrating Trauma Are Correlated

Southern Medical Journal, 2003
Trauma surgeons have observed an increased rate of penetrating trauma during periods of increased unemployment.During a 10-year period, the rate of unemployment in a metropolitan area was compared with the rate of intentional penetrating trauma at two Level I trauma centers. The total number of trauma cases was recorded.

Comparative rates of dermal penetration of insecticides in mice

Toxicology and Applied Pharmacology, 1981
Abstract Dermal penetration of 14 radiolabeled insecticides into ICR mice was studied. Permethrin penetrated most rapidly ( T 0.5 = 5.9) while malathion penetrated least rapidly ( T 0.5 = 130 min). Within 5 min after application some toxicants were in the blood, and measurable quantities of radioactivity from the majority of toxicants tested were

Rate of Penetration of Ions into Erythrocytes

Acta Physiologica Scandinavica, 1942
Summary.The red corpuscles contain much larger amounts of acid soluble phosphorus compounds than the plasma. The difference is only maintained as long as an active process, an alternative phosphorylation and dephosphorylation, takes place in the corpuscles, a process which, was studied by measuring the rate of penetration of labelled phosphorus into ...

Optimal Market Penetration Rates of VICS

2011
VICS (Vehicle Information and Communication System) is a digital data communication system which provides prompt and useful information on current traffic conditions — such as traffic congestion, accidents, or link-travel time — to drivers via car navigation equipment. VICS was described in detail in Chapter 5.

Influence of Penetration Rate on Penetrometer Resistance

Journal of Geotechnical and Geoenvironmental Engineering, 2011
Penetration resistance in fine-grained soils varies with the rate of penetration. Considering undrained behavior as a reference, as the rate of penetration is reduced, soil resistance increases because of the effects of partial consolidation and soil strengthening immediately ahead of the probe.

Slow Rate Penetration of Packaging Films

Journal of Plastic Film & Sheeting, 1990
A detailed evaluation of the slow rate penetration resistance measure ment was conducted on twenty-two different monolithic, coextruded, or laminated flexible barrier packaging films using five different probe geometries. No universal change in penetration resistance with penetration rate was found.

Penetration-Rate Performance of Roller-Cone Bits

SPE Drilling Engineering, 1987
Summary The rate of penetration (ROP) obtained with a roller-cone bit is limited by either the cuttings-generation or cuttings-removal process. An ROP model that includes the effect of both the initial chip formation and cuttings-removal processes is presented.

Correlation of Standard Penetration Test Results with Vibracore Sampler Penetration Rates

1972
A correlation between the penetration rates of a vibratory underwater sampling device and blow counts from the conventional standard penetration test and the continuous-drive cone penetration test is described. Although limited test data are available, the correlation shows promise for low blow count underwater soil deposits. A practical example of the

Comprehensive Drill-Rate Management Process To Maximize Rate of Penetration

Proceedings of SPE Annual Technical Conference and Exhibition, 2006
Abstract The operator's drill rate management process is designed to maximize rate of penetration (ROP) in every foot of hole drilled. Due to its quantitative nature and the degree to which it is incorporated into all phases of the drill well process, the operator believes it to be the industry's first comprehensive ROP design process ...
